Novel apparatus for detecting pulling force of hoisting-chain

Abstract

The invention relates to an apparatus for detecting pulling force of a hoisting-chain. The apparatus comprises a fixed station, a hydraulic cylinder and a chuck; multiple support columns are arrangedbelow the fixed station and support bars are arranged between adjacent support columns, one end of the up end of the fixed station is provided with the hydraulic cylinder, and the other end is provided with the chuck; the chuck is fixed on the fixed station through a fixed plate, the chuck and the fixed plate are connected by employing a telescoping structure, the other side of the fixed plate isprovided with a hinge jointing piece, and the hinge jointing piece and the chuck are fixedly connected. The apparatus is advantageous in that compared with prior detecting apparatuses, fixed connection between the chuck and the fixed plate of the novel apparatus for detecting pulling force of the hoisting-chain is changed by the telescoping connection between the chuck and the fixed plate, spacingbetween the chuck and the fixed plate can be adjusted, furthermore spacing between the chuck and the hydraulic cylinder can be adjusted, in order to satisfy detection of the hoisting-chains of different lengths; the hoisting-chains of different lengths can be detected, detection apparatuses are not needed to replace, and detection cost is substantially reduced.

Description

technical field [0001] The invention relates to the technical field of wire rope tension detection, in particular to a novel lifting chain tension detection device. Background technique [0002] In hoisting tools such as crane hooks and chain hoists, different types, materials, and steel wire ropes of manufacturers often have different stress limits. It is impossible to use the same standard to measure all similar products. Batches of products are first inspected to understand the limit of the force of the batch of products. This often causes a waste of production time, and there is a hidden danger in production safety if it is not detected. [0003] In view of the above phenomenon, the patent CN 202938951 U discloses a lifting chain tension detection device, which includes a fixed platform, a hydraulic cylinder and a chuck. One end of the end face is provided with a hydraulic cylinder, the other end is provided with a chuck, the chuck is fixed on the fixed table through t...

This often causes a waste of production time, and there will be hidden dangers to production safety if it is not detected

[0003] In view of the above phenomenon, the patent CN 202938951 U discloses a lifting chain tension detection device, which includes a fixed platform, a hydraulic cylinder and a clamp. One end of the end face is provided with a hydraulic cylinder, and the other end is provided with a chuck. The chuck is fixed on the fixed platform through a fixed plate. Different batches of imported products are inspected to understand product performance for safe production; however, the inspection device still has certain defects: because the distance between the chuck and the hydraulic cylinder is fixed, it can only be used for lifting chains of the same length. Therefore, to detect lifting chains of different lengths, it is necessary to replace the detection device, which greatly increases the detection cost
