Steel wire rope protection device of titled creeper of hoisting machine

Abstract

The invention discloses a steel wire rope protection device of a titled creeper of a hoisting machine, comprising two parallel side plates, wherein the side plates are respectively provided with a group of upper slideways and a group of lower slideways; a tightening rope wheel and a loosening rope wheel are arranged between the two parallel side plates; a wheel shaft of the tightening rope wheel is matched with the upper slideways and slides along the upper slideways; a wheel shaft of the loosening rope wheel is matched with the lower slideways and slides along the lower slideways; a steel wire rope passes through the surfaces of the tightening rope wheel and the loosening rope wheel; the wheel shaft of the tightening rope wheel is provided with a U-shaped fixed frame, the opened end of which is fixedly connected with the wheel shaft and the closed end of which is horizontally connected with a guide rod; a pressure spring is sleeved on the guide rod, and the outer end of the guide rodpasses through a fixed plate and is connected with a approach switch; the wheel shaft of the loosening rope wheel is provided with a U-shaped fixed frame, the open end of which is fixedly connected with the wheel shaft and the closed end of which is horizontally connected with a tension spring, the other end of the tension spring is connected with a fixed support, and the outer end of the wheel shaft of the loosening rope wheel is connected with the other approach switch. In the invention, the power off of a system is controlled through the switching on or off of the approaching switches, so that the aim of protecting equipment and the steel wire rope is achieved.

Description

[0001] Technical field: [0002] The invention relates to a material lifting system for an inclined climbing car of a hoist, in particular to a steel wire rope protection device for an inclined climbing car of a hoist, which prevents broken ropes and reverse winding faults caused by failure of upper and lower limit switches during the operation of the climbing car. Background technique: [0003] At present, the drum wire rope lifting system is used in the inclined climbing car of the hoist. In the control system, the travel switch is routinely used to set the upper and lower limit positions of the hopper. During operation, the failure of the upper and lower limit switches often leads to failure. The wire rope is broken when the hopper is pulled over, and when the downlink fails, the reverse winding rope will be damaged and the wire rope will be damaged. Contents of the invention [0004] In order to avoid the failure of the upper and lower limit travel switches of the exis...
