Description

Monorail crane driving part braking self-adaptive device Technical Field The invention belongs to the technical field of mine transportation, and particularly relates to a braking self-adaptive device of a driving part of a monorail crane. Background Underground transportation refers to the operation of transporting ore and waste rock from a mine site of a stope to a shaft yard, skip well bin or the ground by mechanical equipment. The transportation mode is divided into rail transportation and trackless transportation. Rail transportation is commonly used for an electric locomotive to pull a train of mine cars along a rail. In the underground auxiliary transportation vehicle of the coal mine, the monorail crane locomotive has the advantages of strong loading capacity, continuous transportation without transferring, and the like, and is widely applied to various large coal mines. The driving part is an important component of the monorail crane, the driving part bears the weight of the driving part by the bearing wheels, the traction force is generated by rolling friction between the driving wheels of the driving mechanism and the track, and the braking force is generated by sliding dry friction between the brake pad of the braking mechanism and the groove at the bottom of the track groove. Along with the improvement of the national importance degree of coal mine safety production, the safety performance requirement of the monorail crane is higher and higher, and the locomotive running process not only needs to have larger traction force, but also needs to have reasonable and reliable braking force, so that the safety of the monorail crane operation is ensured. The prior patent application publication number is CN112810634A, the patent name of the invention is that a hydraulic motor in a driving support is used for providing power and braking force for running of the monorail crane driving device, a driving wheel driven by the hydraulic motor is tightly pressed against a track of a monorail crane guide rail under the action of a clamping force, friction force between the driving wheel and the track provides power for running of a locomotive, a brake cylinder of a brake device is provided with a rod cavity, an oil inlet brake spring is contracted for energy storage, a brake block is separated from the track, and the monorail crane driving device realizes running, otherwise, the brake cylinder releases hydraulic oil, the brake spring stretches by self elasticity and enables the brake block to tightly press the track, so that the braking of the monorail crane driving device is realized, the braking performance is strong, the integral stability and safety performance are effectively improved, and the integral working efficiency is improved. However, the researches show that the scheme has certain defects in use; 1. The braking mode has the defects that the existing monorail crane is divided into a driving wheel braking mode and a brake pad emergency braking mode (the patent scheme), the driving wheel braking mode reduces the friction between the driving wheel and a track through the reduction of the rotation speed of a driving motor, and the braking mode is low in efficiency, and also causes serious abrasion of the driving wheel so as to influence traction force; 2. the emergency braking is a braking method adopted under the condition that the speed is too high due to the fact that conventional braking is invalid, the emergency braking is oil cylinder unloading, brake pads and a track are locked under the action of the pre-tightening force of a spring, the braking force cannot be adjusted according to real-time working conditions, the emergency braking locking of the brake pads can enable the monorail crane to rapidly slow down, the swing amplitude of a locomotive on the track is too large, and transportation accidents occur. In summary, the braking structure of the existing monorail crane system has certain drawbacks and does not meet the requirements of people, and therefore, a braking self-adaptive device of a driving part of the monorail crane is developed.
