Tiejian Heavy Industry "Crafters' Spirit" Build China's First Full-computer Three-armed Rock Drilling Trolley

On March 19th, the first domestic full-computer three-armed rock drill trolley was rolled off by the company. This is the company's compliance with the "Internet +" smart manufacturing era needs, to adapt to market needs, promote the interconnection of man-machine, through data analysis and intelligent manufacturing, "the spirit of craftsmanship" build equipment manufacturing "new d". Its birth means that companies are implementing the national “Belt and Road” strategy with practical actions, entering the global rock drilling equipment industry from a high starting point, strengthening the Chinese market and becoming an international market.

This full-scale computerized drilling rig relies on intelligent data acquisition and control system to achieve precise positioning of the whole machine in the tunnel and multi-arm synchronous attitude adjustment, one-button activation, and multi-rigid arm automatic operation. The drilling rig is designed by inputting parameters such as drilling position, size, depth, and angle designed by the drilling plan, and automatic point-finding and high-accuracy automatic drilling operations are performed through a computerized target path planning and control system. In other words, the equipment is completely intelligent, and it is possible to shorten construction preparation time by more than 90% without manually measuring the contour of the tunnel and the location of the blasthole; the position, angle, and number of holes per hole in the hole map of the excavation section. Both the moving sequence and the direction light are automatically performed by the on-board computer according to a pre-optimized scheme. Positioning holes and drilling cycles for all drilling holes are completely automated by the computer. The drilling efficiency is high, and 5m drilling can be completed within 2 minutes. Depth; Fully computerized drilling rigs save over 50% of material cost by controlling over-under digging; the tunnel excavation profile is highly consistent with the excavation contour of the tunnel design, and the tunnel section profile is well formed; the car is equipped with a set of Complete geological analysis system and safety alarm system, real-time monitoring, recording and management of the entire drilling process information, and automatic analysis of geological conditions; equipment set intelligent drilling, bolt construction, contour scanning of the excavation surface, shotcrete thickness detection , long-distance communication and data exchange, advanced geological exploration and analysis, with grouting and pipe shed support, combined with drug charging, and mane in one of eight functions, breaking through A number of bottlenecks tunnel construction.

China's first full-computer three-arm rig

It is understood that today's tunnel excavation construction methods are mainly divided into shield method and drill and blast method. The shield tunnel construction method refers to the use of a shield machine for excavation, support, excavation, construction of a tunnel full Mechanized full-section construction method. Drilling and blasting method is a traditional tunnel construction method. Drilling and blasting are performed on the rock mass to achieve the purpose of excavation. The traditional drill and blast method has a low safety factor, heavy environmental pollution, and high labor intensity of workers. However, the construction is flexible. The cross-sectional shape of the tunnel is variable in size, strong in geological adaptability and relatively low in equipment cost. Therefore, it is used in the development of mountain tunnels and large underground spaces in China. Dominant.

In order to completely change this situation, Tiejian Heavy Industry has focused its attention on the world's advanced drilling rig equipment development. It has a high degree of mechanization and fast drilling speed. It is not only used for tunnel rock excavation, but also widely used for drilling. , spray anchor support, grouting reinforcement. At present, most of the hydraulic rock drilling rigs on domestic construction sites are imported from abroad. The first domestic rock drilling equipment that is currently off the assembly line is a high-end drilling rig suitable for China's national conditions and is nearly 30 percent cheaper than similar imported products. %, to meet the requirements of economy, application, advanced and reliable use, to realize the localization of digital drilling rigs, to reach the international advanced level, and to achieve another major breakthrough in the tunneling of “China’s wisdom”, filling in the construction machinery industry in China. The gaps in the construction equipment of the tunnel construction have increased the construction efficiency and construction quality. At the same time, it has also led the advancement of other tunnel mechanization equipment. It is of great significance to the revitalization of national industries, the promotion of mechanized construction and the development of high-end underground engineering and equipment.
