Fully mechanized face hydraulic support pushing push rod pose sensing device, fully mechanized face hydraulic support pushing push rod mechanism and method

Abstract

The invention discloses a fully mechanized face hydraulic support pushing push rod pose sensing device, a fully mechanized face hydraulic support pushing push rod mechanism and a method. The sensing device comprises a fully mechanized face, the fully mechanized face comprises a plurality of hydraulic support bases, and a pushing push rod of each hydraulic support base is connected with a middle groove of a scraper conveyor; left and right sides of each pushing push rod are provided with a left pose sensing unit and a right pose sensing unit which are used for sensing the pose of the pushing push rod in real time; and a central signal processing unit senses the deviation degree of the pushing push rod according to the displacement fed back by the left pose sensing unit and the displacementfed back by the right pose sensing unit, and performs adjustment through an execution mechanism. The pose of the pushing push rod is sensed in real time and adjusted in real time, so that it is guaranteed that the pushing push rod is located in the middle, and the mechanism is simple, quick in response, high in precision and high in cost performance.

Description

technical field [0001] The present invention relates to a fully mechanized mining face push rod position and posture sensing device, a fully mechanized mining face hydraulic support push rod mechanism and method, in particular to an automatic perception of the position and posture of the hydraulic support base of a fully mechanized mining face in a coal mine, belonging to The base of the hydraulic support moves to the field of automatic perception of pose. Background technique [0002] The hydraulic support base is one of the key electromechanical equipment in the fully mechanized mining face. The realization of the automatic follow-up control of the hydraulic support base is to realize the "fewer people" and "unmanned" mining of the fully mechanized mining face, improve the working conditions of workers, and reduce labor costs. A necessary condition for strength. During the use of the hydraulic support base in the fully mechanized mining face, it has to withstand various c...

Problems solved by technology

[0004] One end of the pushing hydraulic cylinder of the base of the hydraulic support is connected by a hinge of the pin shaft, and the pushing hydraulic cylinder only provides thrust or pulling force, and cannot be guided. Therefore, during the moving process of the hydraulic support base, the pushing push rod is easily affected by the scraper in its working plane. Affected by factors such as the working resistance of the trough in the middle of the conveyor, there will be left and right swings, which will shift the middle position, resulting in the inclination of the trough in the middle of the scraper conveyor, resulting in uneven scraper conveyor body in the fully mechanized mining face, affecting the scraper conveyor The straightness of the fuselage makes the straightness of the fuselage unable to meet the requirements of production and use, resulting in the breakage of the scraper chain, the wear of the middle groove of the scraper conveyor and the serious deformation of the fuselage, which in turn causes a series of failures, and even the entire coal mining process Can not operate normally, there is a huge security risk

[0005] At present, during the autonomous follow-up process of the existing coal mine hydraulic support base, the pose of the push rod is not sensed, and the influence of the push rod pose on the middle groove of the scraper conveyor is ignored, so a good working surface cannot be guaranteed.
