Description

Technical Field

[0001] The utility model relates to the technical field of underground coal mine operating equipment, and more specifically, to a cable winding and releasing vehicle for a fully mechanized mining working face chute. Background Art

[0002] At present, the fully mechanized mining face of coal mines mainly adopts fully mechanized mining units equipped with hydraulic supports, coal mining machines and scraper conveyors for coal mining operations. The chute is equipped with transfer machines, crushers, belt conveyors, etc. for coal transportation. The power supply equipment (mobile transformers, combination switches, etc.) for coal mining machines, scraper conveyors, transfer machines, crushers, etc. is generally placed on the equipment train. When the equipment on the working face is installed, high-voltage power supply cables need to be laid, and when the working face is advanced, the cables need to be recovered. The annual cable recovery and laying volume of a single coal mine reaches tens of thousands of meters.

[0003] Taking the mining process as an example, when the equipment train moves forward, the 10kv cable on the high-voltage side needs to be removed from the hook on the side of the lane and placed on the cable car of the equipment train, arranged neatly in the shape of "0" or "8". Each cable is about 500 meters long, and the cable diameter can reach Φ100mm. It is relatively thick, heavy and hard. The traditional method requires a winch to cooperate with manual carrying and pulling operations, and requires about 15 people to work at the same time. It requires a large number of people, high labor intensity, and low operating efficiency. The current cable reel usually has a high chassis, which is difficult to meet the operating requirements of low spaces. The cable reel is set horizontally, the cable storage distance is short, and manual cooperation is required to take and hang the cable, and the manual workload is still relatively heavy.
