Lifting appliance for loading and unloading special vehicle balance elbow

Abstract

The invention relates to a lifting appliance for loading and unloading a special vehicle balance elbow. The lifting appliance comprises a compensator (1), a C-shaped frame (2) and a balance pry bar (3), wherein the compensator (1) can compensate in-place deviation, and the C-shaped frame (2) can shorten a resistance arm at one side of the vehicle balance elbow; the C-shaped frame (2) is connectedwith the compensator (1) and the balance pry bar (3) through connecting rings (4); and the lifting appliance is connected with lifting equipment through the compensator (1). According to the lifting appliance, only one person and a small field are needed, the operation for loading and unloading the balance elbow can be easily and safely completed, the manpower site is saved, the use is simple andconvenient, the lifting is safe and reliable, and the adaptability is strong.

Description

technical field [0001] The invention relates to the technical field of special vehicle manufacturing, in particular to a spreader for loading and unloading a balance elbow of a special vehicle. Background technique [0002] The balance elbow is a key component of the running system of special vehicles, and is used for the connection between the wheels and the vehicle body. Due to its weight and location, installation and disassembly are very difficult: because of its large weight, lifting equipment such as cranes and cranes must be used; because its location is located on the side deck below the protruding fenders on both sides of the special vehicle body, When disassembling, if ordinary lifting chains or slings are used, long and thick metal rods (or tubes) must be used together, and multiple people need to press down hard to maintain the balance of the metal rods (or tubes) without causing damage. The balance elbow slips off, causing production accidents. At the same tim...

AI Technical Summary

Problems solved by technology

Due to its weight and location, installation and disassembly are very difficult: because of its large weight, lifting equipment such as cranes and cranes must be used; because its location is located on the side deck below the protruding fenders on both sides of the special vehicle body, When disassembling, if ordinary lifting chains or slings are used, long and thick metal rods (or tubes) must be used together, and multiple people need to press down hard to maintain the balance of the metal rods (or tubes) without causing damage. Make the balance elbow slip off, causing production accidents

At the same time, when installing the balance elbow, the position must be very accurate, and ordinary lifting chains and other spreaders are all rigid parts. If you want to lift the balance elbow to a very accurate position and height, it is difficult to achieve it by simply controlling the crane. The installation operator and the crane operator have repeatedly coordinated and cooperated to achieve

In short, the use of ordinary spreaders requires sufficient manpower, a large enough space, careful operation and full cooperation, which has caused great difficulties in the manufacture and maintenance of special vehicles.
