Coal mining machine travelling monitoring system based on hydraulic limiting device

Abstract

The invention discloses a coal mining machine travelling monitoring system based on a hydraulic limiting device. The coal mining machine travelling monitoring system comprises an upper monitoring computer, a hydraulic limiting device arranged on a coal mining machine body and a travelling monitoring box arranged in a cab. The hydraulic limiting device comprises a V-shaped support and two hydraulic limiting mechanisms arranged on the V-shaped support; the V-shaped support is composed of two sliding beams, and a pushing hydraulic cylinder is arranged between the middles of the two sliding beams; each hydraulic limiting mechanism comprises a hydraulic supporting column, a limiting base and a hydraulic telescopic cylinder; an electronic circuit board of the travelling monitoring box is provided with a first controller, a second controller, a first data storage unit and a second data storage unit; and the pushing hydraulic cylinder is controlled by the first controller, and the hydraulic telescopic cylinder and a supporting hydraulic cylinder of each hydraulic limiting mechanism are controlled by the second controller. The coal mining machine travelling monitoring system is simple in structure, reasonable in design, simple and convenient to operate, good in using effect and capable of solving the problems of relatively poor stability and relatively low safety of the machine body in the large-inclination-angle coal mining process.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a monitoring system for coal shearer walking based on a hydraulic limit device. Background technique [0002] Nowadays, with the development of the coal industry, the shearer has more and more functions, and its own structure and composition are becoming more and more complicated, so the reasons for the failure are also complicated. While improving the performance of the shearer itself, the safety monitoring function of the traveling mechanism of the shearer is also very demanding, so the stable state of the traveling mechanism directly affects the stable operation of the entire shearer, and the shearer The mechanical structure of the traveling mechanism and the performance requirements of the traveling motor are very high. However, most of the existing coal mining machines are not equipped with a dedicated walking monitoring system. During the actual coal mining process, the drivers rely ...
