Protective device of elevating mechanism of stacker-reclaimer

Abstract

The invention discloses a protective device of an elevating mechanism of a stacker-reclaimer, which aims at overcoming the shortcomings that a bucket wheel of the traditional stacker-reclaimer makes an elevating motion by using only one wire rope, and the sudden fracture of the wire rope can easily cause safety accidents to people or the device, influence the regular production and increase the repair cost. In the invention, the elevating mechanism is provided with two parallel wire ropes, the top of a stand column and a bucket wheel arm support are respectively provided with two parallel sets of pulley blocks corresponding to the wire ropes, wherein the head ends of the wire ropes are respectively fixed on two coaxial rollers of a hoister, the tail ends of the wire ropes are fixed on a hoister platform, and a balancing device which is connected with the tail ends of the two wire ropes is installed on the hoister platform. When one wire rope suddenly fractures, the other wire rope alone can maintain the balance of the bucket wheel arm support, can not cause damage to the stacker-reclaimer or result in personal safety accidents, and can gain time for the replacement of the wire rope, thereby greatly lowering the repair cost, and ensuring the safe and regular production.

Description

technical field [0001] The invention belongs to a protection device, in particular to a device for preventing accidents after a rope break of a pitch mechanism of a stacker-reclaimer. Background technique [0002] The bucket wheel of the stacker-reclaimer is the main working part of the machine. The bucket wheel needs pitching movement during work. The pitching mechanism of the stacker-reclaimer is set up for the pitching movement of the bucket wheel during work. The structure of the pitching mechanism is that one end of the wire rope is wound on the drum of the hoist and fixed, and the other end is passed around the top of the stacker-reclaimer column and the pulley block on the bucket wheel arm frame, and then fixed on the hoist in the stacker-reclaimer column. on the platform. The drum of the hoist rotates positively and negatively, so that the bucket wheel can be lifted and lowered. [0003] In the freight yard, the busy loading and unloading work of the stacker-reclai...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the fact that the steel wire rope used for the pitching motion of the bucket wheel of the existing stacker-reclaimer is single, and once it breaks suddenly, it is easy to cause safety accidents for people and machines, affect normal production, and increase repair costs. Disadvantages, provide a protective device for the stacker-reclaimer pitch mechanism
