    Innovative products to create famous brand of rock drilling machinery
    In 2008, Li Yongsheng led the team innovation starts high-speed rock drilling machine R & D tunneling, he solved a series of technical problems of high speed drilling machine, technology innovation more than 40, more than 10 patents. Drilling machine is a kind of engineering machinery, mainly used in tunneling and mining, construction, highway, railway, mine is essential in the construction of hydropower, its performance, directly determines the construction schedule, so it is a very important equipment in construction machinery. 
    Tunneling the company research and development with high speed drilling machine is currently on the market the highest recognition of rock drilling machinery products. Tunnel drilling equipment with high speed impact 2000 times per minute, the key parts to withstand high speed impact, torsion, the service condition is very bad, the key parts are damaged easily, so the service life of key parts are the key factors to the overall performance of high-speed drilling with the effect of tunnel excavation, is the bottleneck restricting the development of rock drilling machinery products. After hard work, in 2008 August to produce the first batch of rock drilling machine and put into Beijing Shanghai high-speed Tiexi thirsty construction site Ma section test, after repeated research trials, will greatly the service life of wearing parts to improve the drilling machine, in a leading position in domestic drilling machine industry.
    The piston is work key parts produce the impact energy of rock drilling machine, is one of the main vulnerable parts, piston service life directly determines the performance of the drill, Li Yongsheng personally to the construction site for the industrial test, the failure of the piston analysis one by one analysis, test and microstructure of hardened layer gradient, influence law analysis of carburized layer depth and microstructure of life, after parts materials testing, process optimization, industrial test, failure analysis, finally determined by carbon nickel chromium molybdenum vanadium steel alloy piston material, to replace the original medium carbon alloy steel, the service life of up to 6000 meters, much higher than the average service life of similar products in the domestic 2000 - 3000 meter.
    The spiral rod is one of the most vulnerable parts of rock drilling machine, it is in the process of working under the sliding friction, extrusion force and torque of the role. Therefore, the spiral rod service condition is very bad, the spiral rod at present domestic production are high strength, high hardness, high wear resistance, but the claw is easy to fracture problems, seriously affecting the service life of the spiral rod. After repeated tests, successfully solved the fracture problem of the spiral rod, the cumulative footage have reached more than 6000 meters, by the user's consistent high praise.
    Bit tail set is wearing parts of rock drilling machine, after the completion of processing is pressed into the rotating sleeve installed to use, drilling in the use of drill, drill tail sleeve and the drill rod shank matched, and the drill rod in continuous impact, rotary piston under the action of the brazing tail set, is of great impact force, lead shank sleeve six party serious wear and tear, reduce the service life of drill tail sleeve. He made of carburizing steel shank sleeve study employed at home and abroad, the surface hardness, hardness in the center and the effective depth of hardening layer and microstructure were analyzed, found the reason of the failure of drill tail set, after the material and process test, optimization of shank sleeve material and the best heat treatment process, after processing, the technical indicators are in line with the requirements of heat treatment technology is made, through industrial test proves that the service life of more than 6000 meters, reached the requirements of the program for tackling key problems.
