In the process of stone construction, when a large amount of hard rock needs to be broken and blasting cannot be used, it is a headache for the construction party, except for the static blasting method of regular using large "breaking hammer" chiseling and "rock expansion agent. Many construction parties will also consider the use of "splitting machine", "splitting rod", "airborne hydraulic splitting machine" and other rock splitting, splitting of hydraulic equipment to improve crushing efficiency, reduce construction costs, but what kind of equipment power is stronger, higher output? Who will be eliminated in the end? In this regard, the reporter interviewed the rock hydraulic splitting equipment manufacturers "Chongqing static explosion Engineering Technology Co., Ltd." technical director Wang Yuan.
 
General introduction to reporters, this kind of equipment can actually be divided into three categories:
 
The first category,Small hydraulic splitting machine: also called hydraulic splitting gun, small hydraulic power station with a few hand-held hydraulic gun, more convenient. In the 1980 s, the Germans began to use the wedge block principle to manufacture this kind of equipment. It was imported for rescue in the early days in China. It was hydraulic demolition equipment. It was quite good for individual rock splitting and concrete breaking. Large-scale rock splitting appeared to have limited power. Domestic production started more than 10 years ago with reference. Basically, the drilling diameter was within 5cm. Although there were many domestic manufacturers, the technology was relatively mature, however, it is not used in rock mining, and it is rarely used in small-scale and small-volume projects.
 
 
The second category,Airborne hydraulic splitter: also called large-scale airborne splitter, which is also inserted into the hole by the principle of wedge (one middle wedge and two reverse wedges). The middle wedge moves forward between the two reverse wedges by the action of hydraulic pressure, releasing large energy from the inside to the outside, destroying its structure from the inside of the rock, and splitting the rock in a predetermined direction.
 
 
This kind of splitting machine/splitting machine is equivalent to making the hand-held splitting gun bigger, and the external hanging is hoisted on the excavator and connected to the hydraulic system of the excavator as the driving force. This equipment was developed by two companies (military and civilian) in Japan decades ago and entered the country more than 10 years ago. This is the real meaning of rock hydraulic splitting equipment used in mines and earth and stone construction. The diameter of the drilling holes is 11cm and 14cm (the diameter was very severe at that time), but soon the equipment also faced the problems of wedge group deformation, expansion and contraction failure, and fracture soon after encountering hard stones.
With the application of this equipment in Japan in China, many domestic manufacturers have sprung up after 2010, including Guangdong, Shanghai, Hebei, Hunan, Shandong, Shanxi...
In this process, there are also some evolutions, such as drilling and splitting (also produced in Japan), and some manufacturers are equipped with a small hydraulic power station separately. There is an independent hydraulic driving source without connecting the hydraulic pipe of the excavator. The disadvantage is that the overall mobility is poor and the power supply or power generation is separately connected. However, the use pressure of these two kinds of airborne splitting machines, splitting machines or mountain cutting machines is only tens of Mpa (single cylinder power and effect are limited).
Japanese enterprises have made great efforts to study this equipment for decades, but there is always a fatal defect: even if the wedge is made of very good steel in the country, once it encounters a hard stone, it will deform or even break if it cannot carry it for a few days (it cannot carry it for many days made in China). therefore, the cost of replacing this vulnerable part cannot be reduced all the time, resulting in the disappearance of this product.
Facts have proved that the wedge-type principle is still very stable and durable on Germany's small splitting guns, but the durability of large-scale airborne mountain-cutting equipment is always a bottleneck, but we have to admit that compared with domestic products, the two Japanese products are among the top in the world so far, and their technological maturity and stability are much better than those of domestic imitation. If Japan's steel quality and industrial technology are compared with China's, who is better to believe that everyone knows, Japan's steel durability is still difficult to guarantee products that can be used for a long time, and it is even more difficult for domestic products to be durable.
 
Recently, some people are asking about this equipment. Is Shanxi's view quite severe? Has the mountain-opening equipment been done for a long time?
A: Before 2016, it was a fruit company that sold fruits. Can it be a manufacturer of equipment for many years? There is no need to say more. The company's industrial and commercial change records and trademark information can be publicly inquired and directly exposed. Then I will teach you a good verification method. Don't you sell well? Is the equipment very powerful? Find a large mine or large construction site where the equipment has been used for many years in your local area and let me have a look. Can it be implemented?
 
Online can find such equipment overwhelming business information, how to identify the equipment is good, the effect and output can be achieved?
Answer: One hole at a time to crack the stones separately. First of all, it is very difficult to achieve high output in this way. Don't just listen to the sales boast. Seeing is believing when you go to the scene. The sales tell you that their products are used in many places, but only let you look at the test results. This is not believed. The best way is to ask him if he has used this equipment for a long time or has been used for tens of tens of thousands of construction sites, because only one site has long-term use of this equipment on site, you can see the real effect and prove that this equipment can be durable for a long time. It didn't take a few days to buy more than 100,000 yuan and lost too many warehouses.
 
the third category,Plunger type hydraulic splitting machine/rock splitting machine: also called column type rock splitting rod and hydraulic rock splitting machine, it is composed of hydraulic pump station and hydraulic rod (one pump station can be equipped with 6 splitting rods). The ultra-high pressure oil output from the pump station drives the oil cylinder to generate huge driving force, and the rock can be split in a predetermined direction after being extended by the hydraulic piston, utilizing the physical and mechanical characteristics of rock compressive strength and great tensile strength.
It was produced and used in South Korea 1990 s and introduced into Hong Kong, Macao, Guangdong and other places around 2010. The diameter of South Korea hydraulic rods was very large at that time. The diameter of drilling holes was generally about 10.5cm. The degree of automation and stability were quite high, which was difficult for domestic manufacturers to achieve later (the larger the diameter of hydraulic rods, the stronger the technical strength, because it was not as simple as making iron bigger, it is a world-class problem to ensure the stability of the whole system while satisfying the sufficient pressure of the system and the rapid increase of pressure).
The rock crack formed by putting 6 hydraulic rods into it at a time must have a better effect than the wedge type "Class II" above, which is very easy to understand. At that time, each hydraulic rod was about tens of kilograms, which could be put into and extracted from the rock hole in a portable way, which was as convenient as the splitting gun "Class I". However, the plunger type hydraulic rod achieved a larger diameter, and its strength and effect became better. This formed an important factor that the plunger type "Class III" could surpass the wedge type "Class II". In addition, this technical principle was more stable, there is no fatal defect that the wedge block group is easy to deform and break.
In just a few years, there have been many production of this kind of equipment in China. The hole diameter of the splitting rod is mostly about 9cm or 11cm, which is difficult to surpass the South Korea in strength and quality (the fatal defect in China is that it is easy to leak oil, damage or have poor effect in a few days). Until 2014, Chongqing Static Explosion Company introduced the hydraulic splitting rod with a hole diameter of 18cm, the strength and effect are beyond (the increase of the diameter of the hydraulic rod and the diameter of the drilling hole is the performance of a major technological breakthrough, because the increase of the hydraulic rod requires the matching of a whole set of pressure systems, and it is great to be able to support the large-diameter hydraulic rod with hydraulic ultra-high pressure).
 
 
In 2015, the "Static Explosion Brand Super Rock Splitter" revolutionized the technical standards in this field. The diameter of the drilling hole reached 25cm, the weight of a single hydraulic splitting rod was 225.00 kg-500.00 kg (it needs to be hoisted, put in and extracted by a excavator), the use pressure exceeded 150Mpa, and the splitting force exceeded 10,000 tons. This large rock splitting machine/hydraulic splitting machine changed people's view on the low construction output of hydraulic splitting machines/airborne splitting machines at any time, it is an innovative product with independent intellectual property rights.
 
Generally, the splitting machines that we know and see are basically hand-held manual operations. This small splitting machine is not only small in strength, low in output, poor or ineffective on hard rocks (the cracks are shallow and the bottom will float obliquely outward, so we have to pick up the bottom constantly), but also often easy to damage, therefore, for so many years, it has not been used and popularly used (Guangdong and Shandong are the areas where small splitting machines began to be sold earlier in China, but they are basically unused in the local areas and are sold abroad. The reason can be imagined).
 
 
Chongqing static explosion mechanization engineering co., ltd. has completely solved the disadvantages of poor stability and high failure rate common to domestic rock splitting equipment before using the "static explosion brand super rock splitting machine" after so many years and over one million cubic meters of different rock construction (only when it is used repeatedly every day can it continuously solve various problems). At present, it absolutely surpasses all the cracking equipment on the market, and its strength and efficiency completely surpasses and kills all portable hydraulic splitters and airborne wedge splitters at home and abroad.
 
Reporter asked: hydraulic rod, splitting rod diameter small, light weight can be portable to use more convenient, drilling hole diameter 9 to 12cm drilling rig to find some, many mines and site owners have their own, this is a good match ah? Too big will not be inconvenient to use, drilling equipment is not easy to find it?
Mr. Wang replied: Everyone hopes that with small and light equipment, a large amount of cracking stones can be done very well. We also want to, but in fact we can't do it!
We have also upgraded step by step from the early small diameter hydraulic rod to the current maximum drilling diameter of 25cm. If the small one can solve the problem, who will spend so much money and so many years to develop a large diameter rock cracking machine?
There are a lot of small-diameter manufacturers, and the price is very cheap, but hard stones can't produce results, and they can't produce output. This is not the delay of high failure rate. On the contrary, it is difficult for you to find a large diameter, because no manufacturer has this technology. It is a world-class problem to achieve such a high hydraulic pressure and such a fast speed, and to ensure that the whole system is stable and does not leak oil.
If it is too big, it is more troublesome to use a digging machine to hang it, and drilling is also more troublesome, don't we know? Let's think about it, what is the ultimate goal of this equipment used for? Is it to make the effect of stone cracking better, the efficiency of breaking stone faster, and reduce the unit price cost per cubic meter?
That's right! The purpose of making the equipment large is forced by the construction. Compared with the small diameter, the large diameter can widen the interval of drilling holes a lot. The large diameter can make the gap of stone top crack larger and the effect is better. In this way, the crushing output will be much higher. The final cost calculation between the two is carried out. The construction cost per cubic meter is much lower for the large diameter, for those who know a little about this aspect of construction, how will they choose after comparison? No doubt...
Domestic down-the-hole drills for drilling have a diameter of 12 to 14cm, which is the limit. This is because they do not have the matching requirement to drill larger holes, which does not mean that they cannot be solved. We have specifications of 18 and 25cm in diameter. Here, the matching of down-the-hole drill modification and drill specifications has long been a problem. Although drilling large holes is slower, the number of holes will be reduced a lot.
Most of the equipment on the market is for sale, and it can only be sold if it is well drilled and matched. The "Static Explosion Brand Rock Splitter" is completely customized to reduce the unit price cost per cubic meter and advance the construction period during construction.
 
The reporter asked: There are many people selling these equipment, tens of thousands or hundreds of thousands. Is it good to use, the effect and output?
Mr. Wang replied: 1. Don't just listen to the sales introduction. You should go to the construction site and look at the test results. You can't see the equipment that is easy to break down. You must confirm that this kind of equipment has been used on the construction site for many years to solve the hard stones. Only then can you dare to buy it.
2. It depends on whether the parameters of the equipment are at the top of the industry, whether it is speed, strength or effect. Only by comparing more can we see the difference. Only by buying the most powerful equipment can we have the highest output.
3. For the real construction people, it is not how much it costs to buy, but how much the output of this equipment can make the cost of each side cheaper. Tens of thousands, hundreds of thousands, can not buy out the output, oil leakage, broken, it can only be cheap to collect scrap iron.
Too many of these equipment were lost in the warehouse in a few days. It cannot be confirmed that the equipment has been constructed on this construction site for more than tens of thousands of square meters. Please do not believe and buy it easily.
 
It is self-evident to see whether the "static explosive brand rock splitting machine" can eliminate those small "splitting machines", "splitting rods" and wedge-type "airborne hydraulic splitting machines/mountain splitting machines" here, but there are still many people who are old in construction, and they still want to try all kinds of methods and equipment. I hope our experience can make everyone take fewer detours and spend less money.
