Safety braking protection system of aerial ropeway slipping rope

Abstract

The invention discloses a safety braking protection system of an aerial ropeway slipping rope. When an aerial ropeway runs, a monitoring control system picks up speed signals in real time through a speed measurement element and simultaneously remembers monitored states. When dangerous slipping occurs, actuating signals are sent to a steel wire rope capturing device, and simultaneously a voice alarm device gives an alarm. When an excessive speed phenomenon occurs, the actuating signals are sent to a wheel side braking device, and simultaneously the voice alarm device gives the alarm. The safety braking protection system of the aerial ropeway slipping rope integrates monitoring and protection and effectively prevents galloping and slipping rope accidents.

Description

technical field [0001] The invention relates to a transport mechanism drawn by wire ropes such as mining winches and cableways, in particular to an overhead cableway rope sliding rope and a safety braking protection system. Background technique [0002] The aerial ropeway drives the friction wheel on the reducer through the motor as the driving device, and uses the endlessly circulating steel wire rope as the traction load; the tail of the steel wire rope is tensioned by the tensioning device, and the rope pulley is supported along the way to maintain the degree and tension of the steel wire rope between the supporting wheels ; The rope grip device connects the passenger hanging chair with the steel wire rope and then makes a circular line to transport people. Due to its particularity, the safety performance requirements are strict. At present, the safety protection devices of aerial ropeways mainly include: [0003] The electro-hydraulic block-type working brake is instal...

AI Technical Summary

Problems solved by technology

However, under special circumstances, such as: the working brake fails, the coupling is disconnected from the reducer, and the internal gear pair or worm gear pair of the reducer is worn out. "Flying Car" Accident

[0004] In the process of emergency braking, the friction coefficient is reduced, and when the occupants are on one side, one side of the wire rope is overweight, and the tension on both sides of the driving wheel exceeds the limit friction traction between the driving wheel and the wire rope, which will lead to friction between the wire rope and the driving wheel. Slip phenomenon

For the steel wire sliding accident during the operation of the cableway, there is no anti-skid device on the market

[0005] In addition, some mines are equipped with monitoring and protection equipment for aerial ropeways, but they only issue early warnings in dangerous situations and cannot prevent accidents from happening

There is still no complete and reliable safety protection system on the market to solve the problems of wire rope sliding and working brake failure, resulting in many accidents of people being injured by aerial ropeways
