Abstract

The invention relates to a multi-output type coal mining machine traveling mechanism with adjustable height and belongs to the field of coal mine mining equipment. The multi-output type coal mining machine traveling mechanism comprises a box body, a spline shaft, a driving gear, a traveling wheel A, a traveling wheel B, pushing jacks and a pin row, wherein the spline shaft is connected with the driving gear; the spline shaft is used as an input shaft; an idle wheel shaft is fixedly mounted on the box body; a bearing B is coaxially mounted on the idle wheel shaft; the outer side of the bearingB is sleeved with an idle wheel; the idle wheel is meshed with the driving gear as well as a transmission gear A and a transmission gear B which are arranged on two side; a driving shaft A and a driving shaft B are movably mounted on the box body; two ends of each of the driving shaft A and the driving shaft B are sleeved with bearings A; a sliding component sleeves outside each bearing A; the transmission gear A and the transmission gear B are fixedly mounted on the outer sides of the driving shaft A and the driving shaft B; axial pulling rods are mounted between the traveling wheels and thetransmission gears; the traveling wheel A is in meshed contact with pin teeth of the pin row. Through the multi-output type coal mining machine traveling mechanism, the problems of poor mobility of the coal mining machine, serious abrasion of the traveling wheels and frequent halt and maintenance can be improved; and the risk that the top beam is cut by the roller can be reduced.

Description

technical field [0001] The invention relates to a height-adjustable multi-output shearer walking mechanism, which belongs to the technical field of mine mining equipment. Background technique [0002] As the key equipment of the general mining and fully mechanized mining face, the working performance of the drum shearer has a very important influence on the safe and efficient mining of coal mines. The traction system is an important part of the shearer. It is not only responsible for the movement of the shearer during mining operations, but also the size and change of its traction speed are of great significance to the working performance of the whole machine and the efficiency of coal mining. With the emergence of high-yield and high-efficiency working faces and the substantial increase in the power of coal mining machines, and in order to ensure the safety and reliability of mining working faces, chainless traction systems using wheel-rail meshing walking mechanisms have g...
