Coal removal device of crawler walking hydraulic support

Abstract

The invention relates to a coal removal device of crawler walking hydraulic support. The main structure of the coal removal device comprises a case, a flow distribution plate, left and right push plates, a case door, a cover plate, a connecting plate, a positioning plate, a traction ear, a clapboard, left and right case cavities, an electrical control mechanism, a cable rolling mechanism, a cable frame, a hydraulic mechanism and pin bores. The device is designed according to the actual situation of shortwall coal mining under the coal mine and the structural features of the hydraulic support and makes full use of limited space of the support; the coal removal device is provided at the front part of the support base; meanwhile, the electrical control mechanism, the cable rolling mechanism and the hydraulic mechanism are arranged in the case of the coal removal device. Therefore, float coal, coal gangue and rock can be removed by the coal removal device at the front part during walking, and all mechanisms in the case run normally; and thus, ground obstacles in alleys can be removed and all mechanisms are not damaged. The device has advanced and reasonable design, compact structure, and is safe, stable and reliable, and also has a multi-use case; and the device removes obstacles fast and conveniently, rolls cables automatically and lays cables fast and thus is an ideal coal removal device of the hydraulic support.

Description

technical field [0001] The invention relates to a coal cleaning device of a crawler-type hydraulic support, which belongs to the technical field of parts design and manufacture of underground support supports in coal mines. Background technique [0002] The crawler walking hydraulic support is the supporting equipment for short-wall mechanized coal mining in coal mines. [0003] In the tunnels of coal mines, due to the harsh geological conditions and undulating ground, falling coal gangue, rocks and floating coal accumulate in front of the supports, which often hinder the progress of the supports. In addition, the explosion-proof cables used in hydraulic supports also need to be automatically retracted. The hydraulic control components and electrical control components also need to be protected. The hydraulic supports currently used have no function of cleaning floating coal rocks, and have not effectively cleaned up the explosion-proof cables and protected the electrical co...

Problems solved by technology

[0003] In the tunnels of coal mines, due to the harsh geological conditions and undulating ground, there are falling coal gangue, rocks and floating coal accumulated in front of the supports, which often hinder the progress of the supports. In addition, the explosion-proof cables used in hydraulic supports also need to be automatically retracted. The hydraulic control components and electrical control components also need to be protected. The hydraulic supports currently used have no function of cleaning floating coal rocks, and have not effectively cleaned up the explosion-proof cables and protected the electrical components. Hydraulic support has potential safety hazards
