Single-gantry automatic rotation lifting appliance

Abstract

The invention discloses a single-gantry automatic rotation lifting appliance, belonging to the technical field of automobile body lifting appliances. The single-gantry automatic rotation lifting appliance comprises a lifting appliance moving-conveying device which is arranged on a rail, wherein a balancing device is fixedly connected below the lifting appliance moving-conveying device; a rotating ring is connected below the balancing device in a matching manner; the rotating ring is provided with a synchronous belt with racks, and a positioning locking mechanism; the rotating ring freely rotates relative to the balancing device under the meshing action between the racks on the synchronous belt and synchronous gears on the balancing device. The single-gantry automatic rotation lifting appliance has the advantages that the structure is simple, the installation and use are convenient, and the stability and safety of the lifting appliance in the rotation process are effectively guaranteed by means of arranging a centralizing wheel, a circular rail supporting wheel, a synchronous belt pressing wheel, a rolling wheel and a guiding wheel in a balancing frame.

Description

technical field [0001] The invention relates to a car body rotating hanger, which belongs to the technical field of car body hangers, in particular to a single gantry type automatic rotating hanger. Background technique [0002] In the field of automobile production, especially in the assembly workshop, it is often necessary to lift the car with the help of a spreader to carry out various process treatments, assembly of various process accessories and the next process of the car body. transportation. The spreaders used in the current assembly line of automobiles are generally fixed. When workers assemble the chassis parts of the car body, they often need to shuttle at the bottom of the car body to work with their heads up. Security risks. Therefore, it is extremely important to design a car body hanger that can rotate automatically and is easy to operate to reduce the labor intensity of workers and improve work efficiency. [0003] In the Chinese utility model patent spec...

AI Technical Summary

Problems solved by technology

Although this utility model proposes a rotary body sling that can rotate the car body in order to solve the problem that the current sling cannot rotate the car body, the sling is expensive to manufacture and needs to manufacture the arc rack separately; An arc-shaped rack is fixed on both sides of the car body positioning seat to realize the overturning of the car body, so the hoist is bulky and inconvenient to install and transport. Most importantly, the utility model does not provide a The spreader of the gantry overturning body cannot effectively realize the stable rotation of the body under the premise of ensuring the structure of the spreader is simple and the installation is convenient
