Embodiment Construction

[0025] A preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the present invention provides a method for repairing the front transport groove of the continuous miner, comprising the following steps:

[0027] Step 1: utilize gas cutting gun to carry out gas cutting and cutting to the front transport groove of described continuous mining machine, separate the groove body and wear-resistant plate of the front transport groove of described continuous mining machine;

[0028] Step 2: grinding the section formed by the gas cutting of the tank body into the first slope;

[0029] Step 3: replacing a new wear-resistant plate, and grinding the position of the new wear-resistant plate opposite to the first slope into a second slope;

[0030] Step 4: arranging the first slope of the tank body opposite to the second slope of the new wear-resistant plate to form a welding joint, ...

Abstract

The invention discloses a method for repairing a front delivery channel of a continuous miner. The method comprises the following steps: step 1, a gas cutting torch is used for gas cutting of the front delivery channel of the continuous miner so as to separate a channel body of the front delivery channel of the continuous miner from a wear-resisting plate; step 2, a fracture surface formed after gas cutting of the channel body is polished into a first slope; step 3, the wear-resisting plate is replaced by a new one, and the position, opposite to the first slope, of the new wear-resisting plate is polished into a second slope; step 4, the first slope of the channel body and the second slope of the new wear-resisting plate are arranged to be opposite to each other so as to form a welded junction, and a welding rod is used for conducting welded connection on the welded junction. According to the method for repairing the front delivery channel of the continuous miner, the first slope and the second slope are polished between the channel body and the new wear-resisting plate so that an operator can conveniently conduct welded connection on the front delivery channel of the continuous miner from the outside in an aligned mode; besides, the channel body and the new wear-resisting plate are fixed through a shaft sleeve in a spot welding mode before being welded, so that welding deformation is avoided.

Description

technical field [0001] The invention relates to a repair method, in particular to a method for repairing the front transport groove of a continuous miner. Background technique [0002] The continuous mining machine is a single-chain scraper conveyor, which consists of a main shaft, a sprocket, a chute, a scraper, a chain, a tail drum, a chain tightening device, a tail swing, and a lifting hydraulic cylinder, among which the chute includes the front conveyor There is a wear-resistant plate on the bottom of the trough, the rear trough, and the front trough. The thickness of the wear-resistant plate is about 6mm. After long-term use, the wear-resistant plate will be severely worn and must be repaired in time, otherwise it will be damaged. The chain jamming phenomenon occurs so that the machine is shut down for maintenance, which seriously affects the production schedule of the mine. In the existing technology, the repair of the wear-resistant plate of the front transport tank ...
