Stone coal machine anti jamming hydraulic system won the national utility model patent

Recently, the “Industrial Anti-drilling Hydraulic System” independently innovated by Shimei Mining Machinery Co., Ltd. was granted a utility model patent by the State Intellectual Property Office. This system is applicable to large-torque tunnel drilling rigs and completely solved the problem of stuck-drilling during the drilling process of drilling rigs. Problems, advanced technology in the industry.
According to technical personnel, tunnel boring machines are mainly used for the detection of underground gas and water in coal mines to prevent the occurrence of gas accidents such as outbursts and flooding. It can also be used for ground geological exploration, building foundation reinforcement and other surface engineering drilling, with a wide range of applications. However, in drilling operations, due to poor working conditions or complicated geological conditions, the rotary motor of a tunnel boring machine is often subjected to abrupt changes in work load, and stuck drilling occurs, which can easily cause hole accidents and seriously affect drilling. Quality, reduce production efficiency.
In order to overcome this problem, the scientific and technical personnel of the stone coal machinery company developed a hydraulic system for anti jamming. This system uses a universal hydraulic element. When it is subtly cooperated, the rotary motor is subjected to a sudden increase in the load during work. The energy storage of the feedback signal and the drive of the reversing valve enable the instantaneous reversal of the feed cylinder, which allows the system to resume normal operation and ensure the efficiency of drilling rig drilling. The system is installed on a series of high-torque pit rigs produced by Shimoji Co., Ltd. It is stable, easy to adjust, and reliable in anti-jamming. (This article comes from a stone coal machine)
