Simulation experimental device for push-loose process of scraper conveyor under downhole complex ground condition

Abstract

The invention discloses a simulation experimental device for the push-loose process of a scraper conveyor under the downhole complex ground condition. A pushing mechanism in the experimental device isa key part for connecting the scraper conveyor with a hydraulic support base, the front end of the pushing mechanism is connected with the conveyor through a joint, the pushing mechanism is connectedwith the hydraulic support base through the front end of a piston rod of a pushing jack, and a cylinder body of the pushing jack is hinged to the pushing mechanism. Through the pushing mechanism, push-loose work can be simulated to conduct push-loose on the scraper conveyor, the track line of the scraper conveyor is detected, and a track is corrected; and the experimental device effectively simulates the real environment, data obtaining is more convenient, operation is convenient, and the simulation experimental device can be used in teaching demonstration.

Description

technical field [0001] The invention relates to an experimental device for the pushing process of an underground scraper conveyor in a coal mine, in particular to an experimental device for simulating the pushing process in a fully mechanized mining face and related test processes. Background technique [0002] Coal mine fully mechanized mining equipment is moving from the current automation to intelligent and unmanned. Therefore, it is particularly important to keep abreast of the operating status of fully mechanized mining face equipment, especially coal shearers, scraper conveyors and hydraulic supports. The research on the positioning and attitude determination of machine, scraper conveyor and hydraulic support mainly focuses on the research on the positioning and attitude determination of a single machine. There are still relatively few studies on joint positioning and attitude determination of coal mining machines, scraper conveyors and hydraulic supports, and the on...

Problems solved by technology

[0002] Coal mine fully mechanized mining equipment is moving from the current automation to intelligent and unmanned. Therefore, it is particularly important to keep abreast of the operating status of fully mechanized mining face equipment, especially coal shearers, scraper conveyors and hydraulic supports. The research on the positioning and attitude determination of machine, scraper conveyor and hydraulic support mainly focuses on the research on the positioning and attitude determination of a single machine. There are still relatively few studies on joint positioning and attitude determination of coal mining machines, scraper conveyors and hydraulic supports, and the only few have not deeply analyzed the connection constraint relationship between the three machines and applied them to joint positioning, and seldom consider geological terrain Conditions, in order to study the posture of the shearer, scraper conveyor and hydraulic support and solve some technical problems under the consideration of the joint relationship between the shearer, the scraper conveyor and the hydraulic support, and solve some technical problems, and establish a relevant model based on the actual situation. Simulations to build relevant theoretical structures

[0003] There are still many related experimental devices, such as the combined hydraulic support push test device applied by Huaibei Anlai Electromechanical Equipment Co., Ltd.; the experimental device disclosed in the publication number 103630414B can complete the partial load test of the push mechanism, and the structure is relatively simple, but the function is relatively Single, can only complete specific experiments, poor comprehensiveness

[0004] There is also a hydraulic support test bench and its hydraulic conveying device applied by Zhengzhou Coal Machinery Machinery Equipment Co., Ltd., the publication number is 205471526U. Automated and has no associated sensor elements to analyze test results
