Safe monkey vehicle device convenient to use

Abstract

Due to the fact that floor of a roadway of an underground coal mine is uneven and rugged, when the bottom of a monkey vehicle is far away from the floor of the roadway, the feet of a passenger cannot make contact with a pedal rod of the monkey vehicle when getting on the monkey vehicle, no stable supporting points exist, and the passenger cannot get on the monkey vehicle; when the passenger gets off the monkey vehicle, because the soles of the passenger of the monkey vehicle cannot make contact with the ground, no reliable landing points exist, and the passenger cannot easily get off the monkey vehicle; if the passenger gets on or off the monkey vehicle forcibly when the monkey vehicle moves forwards, a falling injury accident can easily happen, the passenger can easily collide with a miner at the moment of getting away from the monkey vehicle, and the accident may be more serious. The novel monkey vehicle device is used for solving the problems. When a person gets on the monkey vehicle, the pedal rod is pulled downwards due to force so that the person can conveniently get on the monkey vehicle; when the person sits on a lifted seat, a spring device contracts, a spring pulls the pedal rod up through a connecting plate, friction and collision between the pedal rod and the floor of the roadway are avoided; when the person gets off the monkey vehicle, the gravity of the person transfers from the seat to the soles, the pedal rod moves downwards, and it is ensured that the person gets off the monkey vehicle safely.

Description

technical field [0001] The invention relates to a new type of safe transportation tool for auxiliary transportation of personnel in underground mines, which is a convenient and safe monkey car device for getting on and off the car and belongs to the safety field of underground transportation. Background technique [0002] At present, most mines in my country use monkey carts as a means of transportation to transport underground workers. Due to the unevenness and fluctuation of the floor of the underground roadway in coal mines, when the bottom of the monkey cart is higher than the bottom of the roadway, the feet of the passengers cannot touch the pedals of the monkey cart when getting on the car, so there is no reliable support point and the passengers cannot get on. When getting off the car, the passengers of the monkey car cannot fully touch the ground due to the lack of a stable landing point, making it difficult or even impossible to get off the car at this time. It tak...

AI Technical Summary

Problems solved by technology

Due to the unevenness and fluctuation of the floor of the underground roadway in coal mines, when the bottom of the monkey cart is higher than the bottom of the roadway, the feet of the passengers cannot touch the pedals of the monkey cart when getting on the car, so there is no reliable support point and the passengers cannot get on. When getting off the car, the passengers of the monkey car cannot fully touch the ground due to the lack of a stable landing point, making it difficult or even impossible to get off the car at this time. It takes a lot of time to get off the car, which reduces the work efficiency of the workers; if the passengers forcefully get on the car or jump off the monkey car when the monkey car is moving, it is very easy to cause a fall accident, and the monkey car will be damaged at the moment of getting rid of the monkey car. Swaying from side to side, it is easy to collide with miners and cause injury, leading to further expansion of the accident

On the other hand, if the distance between the monkey trolley and the roadway floor is too small, it is easy to rub and collide with the roadway floor or the rails, shorten the service life of the monkey trolley, and cause a large amount of economic losses
