Dragging part of torque shunting thin coal layer mining machine

Abstract

The invention discloses a dragging part of a torque shunting thin coal layer mining machine. The dragging part comprises a dragging shell, a dragging motor, a dragging speed reduction box, a torque shunting gear transmission mechanism, a gap bridge, a traveling shell, a torque shunting gear transmission mechanism and a traveling wheel. When the dragging part of the torque shunting thin coal layer mining machine works, the output shaft of the traction motor transmits power to the dragging speed reduction box and then transmits the power to the traveling wheel through a multi-stage cylindrical gear and a planetary gear after being subjected to transmission speed reduction; the traveling wheel is meshed with a pin row arranged on an emptying side; and due to the rotation of the traveling wheel, the thin coal layer mining machine can travel. The dragging part is driven by the motor, can meet a requirement on underwell explosion prevention and is simple and compact in overall structure; through the arrangement of torque shunting gear transmission mechanism and gap bridge, the coal passing space is enlarged; a coal layer with the height of 0.65 to 1.3 meters can be mined; a demand for mining the underwell thin coal layer can be met; and the mining efficiency of the underwell thin coal layer and the coal resource production capacity can be improved.

Description

technical field [0001] The invention relates to a traction part of a drum shearer, in particular to a traction traveling mechanism suitable for mining thin coal seams in coal mines. Background technique [0002] With the increase of coal mining in our country year by year, the reduction of medium-thick coal seam reserves and the increasingly scarce resources, the mining of thin coal seams has attracted more and more attention from the state and coal production enterprises. Due to poor conditions for thin coal seams, mining is difficult, mechanization is difficult, efficiency is low, cost is high, and the working environment is poor, many thin coal seams have not been mined and utilized due to technical reasons, resulting in a waste of coal resources. In order to ensure the sustainable development of my country's coal resources, mining thin coal seams is a reasonable and effective way. Therefore, it is necessary to develop thin coal seam mining technology and d...
