Mining overhead man-riding device capable of being decelerated at get-off point and use method of mining overhead man-riding device

Abstract

The invention discloses a mining overhead man-riding device capable of being decelerated at a get-off point and a use method of the mining overhead man-riding device. The mining overhead man-riding device comprises an ejection block, a guide assembly and a deceleration device. Multiple inclined grooves are formed in the bottom face of the ejection block. The deceleration device comprises a sliding shaft, a fixing mechanism, a friction deceleration mechanism, traction ropes and rope clips. The friction deceleration mechanism comprises a carrying block, a sliding groove for the sliding shaft to slide is formed between the carrying block and a first boundary face, a rubber layer is arranged on the bottom face of the carrying block, multiple first small holes are formed above the rubber layer, each first small hole is internally provided with a steel column, the periphery of each steel column is sleeved with a first spring, and a steel ball is placed at the top of each first spring. When the overhead man-riding device runs, the ejection block runs on the friction deceleration mechanism under the effect of the guide assembly. The running speed of the single overhead man-riding device can be controlled through the deceleration device, a temporary deceleration effect is achieved in the get-on and get-off processes of an operator, the personal safety of the operator is guaranteed, and therefore the occurrence rate of accidents is reduced.

Description

technical field [0001] The invention relates to the technical field of mining monkey car riding safety, in particular to a mining monkey car that can be decelerated at an alighting point and a method for using the same. Background technique [0002] With the continuous development of coal mines, there is an urgent need for a transportation tool that can reduce the labor intensity of workers and transport workers safely and comfortably. The monkey car has been adopted by coal mines and has been widely used because of its advantages of small equipment investment, small floor space, low operating cost, stable and reliable operation, etc. However, at present, the depth of mine mining is increasing, the workload of coal mining is gradually increasing, and the degree of mining mechanization is also significantly improving. In order to meet the needs of work intensity, operators need to ride monkey cars many times. It is necessary to get on and off the car many times in the inclin...

Problems solved by technology

However, at present, the depth of mine mining is increasing, the workload of coal mining is gradually increasing, and the degree of mining mechanization is also significantly improving. In order to meet the needs of work intensity, operators need to ride monkey cars many times. It is necessary to get on and off the car many times in the inclined alley, although the safety equipment in the prior art provides multiple protections for the personal safety of workers, such as overspeed protection, emergency stop protection for all roadway emergencies, wire rope broken rope protection, and rope drop protection Wait, but the current technology still lacks protective measures for workers getting on and off the car halfway, that is, the monkey car still runs at the original speed when the worker gets off the car halfway, which can easily cause the worker to fall and get injured
