Guiding rail assembly and cable dragging device of coal mining machine

Abstract

The invention provides a guide rail assembly and a coal mining machine cable dragging device.The guide rail assembly comprises a plurality of dragging rails which are sequentially connected, the dragging rails comprise the first dragging rails and the second dragging rails, at least one second dragging rail is arranged between every two adjacent first dragging rails, and the second dragging rails are arranged between the first dragging rails and the second dragging rails. Wherein the first dragging track comprises a first cable groove, a first bottom plate, a first guide rail and a second guide rail, the first guide rail and the second guide rail are detachably arranged on the upper surface of the bottom plate, and the second dragging track comprises a second cable groove, a second bottom plate, a third guide rail and a fourth guide rail. The third guide rail is detachably arranged on the upper surface of the second bottom plate, and the fourth guide rail is fixedly arranged on the upper surface of the second bottom plate. According to the guide rail assembly of the embodiment of the invention, the installation is convenient, the assembly difficulty is low, and a worker can conveniently install the driving chain and carry out maintenance and overhaul.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a guide rail assembly and a shearer cable dragging device. Background technique [0002] The shearer is one of the three machines currently supporting the fully mechanized coal mining face. The shearer will reciprocate during the coal mining process, and the cable of the shearer will move with the reciprocating motion of the shearer, and the cable will bend multiple times, that is, the cable will be superimposed multiple times in the vertical direction, and the cable will be repeatedly bent. The stacking limits the further reduction of the height of the bracket, and at the same time, multiple stacking will cause cable extrusion, excessive bending and twisting, excessive wear, stretching, leakage, falling, and flipping. The cables are guided by the drag rails, and the adjacent cable drag rails are connected by a guide device. [0003] In the related art, the guide device is ...

AI Technical Summary

Problems solved by technology

[0003] In the related art, the guide device is generally installed on the side wall of the cable trough, and the connection method usually adopts a fixed connection or a snap connection, but the fixed connection method is not convenient for installation and maintenance, and has poor practicability, and the snap connection has a great impact on each component. High machining accuracy requirements lead to increased production costs and maintenance costs, which is not conducive to popularization and use
