Abstract

The invention discloses an operation method for moving a fully-mechanized coal winning machine in a large-dip-angle downhill roadway. The operation method comprises the following steps: (1) disassembling a left walking forward operation pipeline interface and a right walking forward operation pipeline interface on an operation table of the fully-mechanized coal winning machine; (2) respectively connecting two phi16mm high-pressure rubber pipes to a left walking forward operation pipeline interface and a right walking forward operation pipeline interface; (3) intersecting the two high-pressure pipelines with the diameter phi being 16 mm in the step (2) into a high-pressure pipeline with the diameter phi being 10 mm through a tee joint with the diameter phi being 16 mm to 10 mm; (4) connecting the high-pressure pipeline which is converged in the step (3) and has the diameter phi of 10mm to a main inlet pipeline interface of a remote control operation quadruple plate valve; and (5) adjusting the position of the roadheader at the upper opening of the inclined roadway; the self-walking difficulty and the self-moving gliding risk of the fully-mechanized excavating machine are avoided, the fully-mechanized excavating machine is remotely operated to walk, and the danger coefficient of operating and moving the fully-mechanized excavating machine is greatly reduced.

Description

technical field [0001] The invention relates to an operation method for moving a fully-mechanized excavator in a downhill roadway with a large inclination angle, and belongs to the technical field of coal mine production. Background technique [0002] In coal mine excavation construction needs to use fully mechanized excavator for excavation. The maximum slope of the fully mechanized excavator is 18°. There is a risk of self-moving and sliding. The driver of the fully-mechanized excavator operates and moves the fully-mechanized excavator on the machine, and the risk factor is high. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an operation method for moving the fully-mechanized excavator down the mountain roadway with a large inclination angle, without the difficulty of self-walking of the fully-mechanized excavator and the risk of self-moving and sliding of the fully-mechanized ...
