The invention provides an assembler for preloading a microseismic sensor on an underground bolt in a coal mine, and belongs to the technical field of coal mine safety monitoring instruments and equipment. The explosion-proof shell is an external steel load-bearing structure with a hollow center and holes at the bottom, and meshing gears are mounted on the inner wall of the explosion-proof shell; the energy supply accessories are located inside the explosion-proof shell, including power supply, motor, and meshing gears, which are inner rotating chambers. The rotation provides kinetic energy; the outer wall of the internal rotation cavity is equipped with gears that can be meshed with the gears of the explosion-proof casing, and the inner wall is roughened, and the rotation can be realized by relying on the sliding track at the bottom of the casing and the energy supply accessories; the fastening clamp is located on the upper part of the explosion-proof casing. It is composed of fastening arm, chain, pull rod and high-strength spring to realize the fastening and sealing with the end of the mine bolt. The assembler liberates the dependence of sensor installation on manpower, improves the accuracy of sensor screw installation, anchoring strength and work efficiency, strengthens the stability of the overall structure, and can meet the requirements of the microseismic system for signal reception.
Description
technical field [0001] The invention relates to a device for installing a signal sensor of a microseismic system in a coal mine, which realizes the efficient and fast installation of the sensor in the coal mine, and promotes the recovery and reuse of the sensor, and in particular relates to an assembly of the microseismic sensor for the pre-tightening installation of the bolt under the coal mine device. Background technique [0002] Due to the frequent occurrence of coal mine rock burst accidents and water inrush accidents, according to the requirements of the National Energy Administration and the Safety Supervision Bureau, a microseismic system must be installed in the rock burst mine to monitor the stress and damage of the surrounding rock of the mine; and in coal mines In the Water Control Regulations, the microseismic system will also be set as a key technical means for water control. However, the cost of microseismic sensors is relatively high, with an average of 15,0...
