Supporting load detecting device for winch and detecting method of supporting load detecting device

Abstract

The invention discloses a supporting load detecting device for a winch. The supporting load detecting device comprises a reel and a belt type brake used for braking the reel and further comprises an extension plate, an anti-shearing block, a jacking hydraulic oil cylinder, a jacking hinge seat and a bottom plate used for bearing the fixed winch. The front side edge of the extension plate is connected with the reel wall of the reel. The lower end of the extension plate is connected with the upper end of the jacking hinge seat. The lower end of the jacking hinge seat abuts against the upper endof the jacking hydraulic oil cylinder. The lower end of the jacking hydraulic oil cylinder is connected with the bottom plate. The anti-shearing block is further connected with the reel wall of the reel and arranged above the extension plate. The invention further discloses a method for winch supporting load detecting. According to the supporting load detecting device, a lot of tedious early-stagepreparation works can be omitted, and supporting load detecting is conducted on the winch efficiently and simply.

Description

technical field [0001] The invention relates to a device for testing the supporting load capacity of a winch, and more particularly relates to a supporting load testing device for a winch and a testing method thereof. Background technique [0002] The winch is a large-scale equipment widely used in marine engineering, electric power, mining, cement, steel, chemical, paper and other industries. According to the design specifications, when the winch vertically lifts heavy objects as a crane, it must be equipped with a band brake for safety. [0003] The supporting load test is to check whether the band brake has full braking ability under the supporting load of the winch. The winch support load design specification generally stipulates that it is 80% of the breaking force of the wire rope, so the tension value is very large. The band brake is used to provide the brake for supporting the load. Before the winch leaves the factory, the capacity of the band brake needs to be teste...

AI Technical Summary

Problems solved by technology

[0006] 1. The space required for the test site is large;

[0007] 2. The winch is moved from the production workshop to the test site, requiring the use of large-scale handling equipment;

[0008] 3. The size of the winch has different specifications, and it takes a lot of financial, material and manpower to make bases and wire ropes of different specifications;

[0009] 4. The supporting load of each specification winch is different, and it needs to be equipped with standard counterweights of different specifications;

[0010] 5. Because the winch support load test is a hoisting test, and the weight of the standard counterweight is large, there is a large potential safety hazard
