Inner clamping type hoisting device for braking drum of automobile

Abstract

The invention relates to an inner clamping type hoisting device for a braking drum of an automobile. The inner clamping type hoisting device is used for hoisting the braking drum. The hoisting device comprises a hoisting shaft, clamping plates, a sleeve, a pulling rod, a locating ring, hinge pins, a hoisting ring and a handle, wherein the hoisting ring for hoisting the hoisting shaft is mounted at the upper end of the hoisting shaft; two clamping plates with symmetric positions are mounted at the lowermost end of the hoisting shaft; the sleeve and the locating ring sleeve the hoisting shaft; the sleeve can be mounted and located through the locating ring; the pulling rod is arranged between the sleeve and the clamping plate; the sleeve and the pulling rod as well as the pulling rod and the clamping plate are respectively connected through the hinge pins; the sleeve and the clamping plates are integrally connected through the pulling rod; the clamping plates at two sides are overturned up and down by using a central line of the hoisting shaft as an axis and are extended and clamped into an inner circle of the braking drum so as to hoist the braking drum. The inner clamping type hoisting device enters and is clamped inside the inner circle of the braking drum; after hoisting, the hoisting device can be used for automatically adjusting the center of the gravity; the operation is simple and convenient, the labor intensity is alleviated, the hoisting is stable, and falling can be avoided during hoisting, so that the potential risk can be eliminated.

Description

technical field [0001] The invention relates to a hoisting device for an automobile brake drum, in particular to a hoisting device of an inner card type of an automobile brake drum, which belongs to the technical field of hoisting. Background technique [0002] In the prior art, the suspenders for hoisting the brake drum are all small suspension hooks. When hoisting, the hook is put into the inner circle of the brake drum, and the surface of the hook pulls the inner surface of the brake drum to complete the loading and unloading. The disadvantages of this kind of sling are: the contact surface of the hook is small, it is easy to decouple, causing safety hazards, and the lifting efficiency is low; the hook is limited by the size of the brake drum, and when the size of the brake drum is small, the hook is not easy to Put it into the inner circle of the brake drum, and it is inconvenient to take it. When the size of the brake drum is large, the weight of the brake drum is grea...

AI Technical Summary

Problems solved by technology

The disadvantages of this kind of sling are: the contact surface of the hook is small, it is easy to decouple, causing safety hazards, and the lifting efficiency is low; the hook is limited by the size of the brake drum, and when the size of the brake drum is small, the hook is not easy to Put it into the inner circle of the brake drum, and it is inconvenient to take it. When the size of the brake drum is large, the weight of the brake drum is greater than the rated load of the spreader, which is not conducive to safe operation

[0003] At present, for large-scale brake drums, ropes are often used for hoisting, and the service life and hoisting efficiency are not high, which does not meet the needs of mass loading and unloading.
