Novel continuous mining machine power cable take-up and pay-off device

Abstract

The invention discloses a novel continuous mining machine power cable take-up and pay-off device. The novel continuous mining machine power cable take-up and pay-off device comprises a cable hook. A crusher suspended slideway is fixed on a top cover of the crusher, and a continuous mining machine suspended slideway is fixed on a top plate of the continuous mining machine through a connecting mechanism; a plurality of cable hooks arranged in rows are fixed on the roadway top plate between the crusher and the continuous mining machine; and a power cable sequentially penetrates through the crusher suspended slideway, the cable hooks and the continuous mining machine suspended slideway. The device has the advantages that the power cable of the continuous mining machine passes through the suspended slideway of the crusher, is erected on the cable hook, and is sent out from the suspended slideway of the continuous mining machine into the wire inlet cavity of the continuous mining machine, thereby effectively avoiding the condition that the power cable falls to the ground, eliminating the possibility that the power cable is scratched by ironware and sharp objects, avoiding the risk of electric shock caused by electric leakage of the power cable, and greatly improving the power supply safety of the continuous mining machine, random automatic folding and unfolding are achieved, only one person is needed for auxiliary monitoring, and the labor intensity of workers is remarkably reduced.

Description

Technical field: [0001] The invention relates to the technical field of coal mine electromechanical equipment, in particular to a novel continuous mining machine power cable retracting device. Background technique: [0002] In underground coal mines, the roadway excavation process of continuous miner is a roadway machine excavation process with relatively high excavation efficiency; the main equipment matched with continuous miner is shuttle car, crusher and large bolter; crusher is relatively fixed equipment , lapped with the tail of the trough belt machine; the continuous miner, the shuttle car and the large bolter are mobile equipment, and the power cable of about 80 meters is moved with the machine. The power cable of the follower is on the ground. In order to prevent the power cable from being crushed by the continuous miner itself and the shuttle car, one person is required to follow the continuous miner during operation, and pay attention to placing the power cable ag...

AI Technical Summary

Problems solved by technology

[0003] There are the following main problems in the conventional method of manually arranging the power cables of the continuous miner: first, the frequency of manually arranging and retracting the power cables of the continuous miner is relatively high, which significantly increases the labor intensity of the operators; It is more likely that the cable will be scratched by iron and sharp objects, and troubleshooting is also more difficult; third, the actual amount of power cables used by the continuous miner cannot be estimated, and the pre-stored power cables on the continuous miner are very messy and difficult to control. The cable brings great difficulties; fourth, after the power cable of the continuous miner is randomly damaged, the risk of electric leakage and electric shock is significantly increased; fifth, when the power cable is reeled on the continuous miner, it is a high-altitude operation, and the labor intensity is relatively high , the safety risk of the power cable being injured by the operator and the power cable being crushed by the continuous mining machine are relatively high; sixth, the field of vision is relatively weak during the excavation period, and there is a safety risk of being hit by the personnel who follow the machine to arrange the power cable
