A mining monkey car that can be decelerated at the drop-off point

Abstract

The invention discloses a monkey car for mining that can be decelerated at the alighting point and its use method. It includes a top block, a pilot assembly and a deceleration device. Several oblique grooves are arranged on the bottom surface of the top block, and the deceleration device includes a sliding shaft. , a fixing mechanism, a friction deceleration mechanism, a traction rope and a rope grip, the friction deceleration mechanism includes a bracket, a chute for the slide shaft to slide is formed between the bracket and the first boundary surface, a rubber layer is provided on the bottom surface of the bracket, and the rubber A number of small holes are arranged on the top of the layer, and a steel column is arranged in each small hole. A spring is sheathed on the periphery of the steel column, and a steel ball is placed on the top of the spring. When the monkey car is running, the jack block runs on the friction deceleration mechanism under the action of the pilot assembly; the present invention can control the running speed of a single monkey car through the deceleration device, and provide short-term The deceleration effect ensures the personal safety of the operating workers, thereby reducing the incidence of accidents.

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
