Description

Lifting type suspension cage for large coal bunker of mine

The technical field is as follows:

the utility model relates to a mine lifting means technical field specifically is a lift formula cage with big coal bunker of mine.

Background art:

the coal bunker is constructed underground. Is built in underground mines. The transportation is extremely inconvenient. The transportation is mainly through the well head. That is, materials and personnel tools need to be transported into the coal bunker, and the personnel tools only need to enter the coal bunker through the direction of the wellhead.

The step ladder is built at the wellhead, but personnel lean on the step of crawling in the construction from top to bottom, and material, multiplexer utensil are put by the rope hoist, and the process is many, the operation is slow, and personnel consume physical power big, occupation time is many, expand brush speed slowly, the safety control degree of difficulty is big, work efficiency is low from top to bottom through the step. It is therefore necessary to build a conveyance at the wellhead. The tool needs to have the following necessary features.

Firstly, need safety, after the personnel enter into at the bottom of the coal bunker, just only can come out from the coal bunker well head again, nevertheless if in case meet the vehicle that the power failure got into and will take place paralysis, take place paralysedly after, lead to the unable business turn over of personnel that enter into the coal bunker bottom, extremely dangerous. Therefore, a person entering the bottom of the coal bunker is required to be a vehicle which can still smoothly come out from the wellhead of the coal bunker under the condition of power failure.

Secondly, the vehicle needs to be compact. The mining area of the underground coal mine is limited, and the difficulty of underground expanding the field is very large.
