Train wheel lifting appliance

Abstract

The invention provides a train wheel hanger, which includes a suspension chain and a hanger. The hanger includes a pull rod, a bracket, an adapter rod and a support rod. The upper end of the pull rod is connected with the suspension chain. The connecting platform of the shaft connecting hole, the lower end of the support rod is vertically and fixedly connected with a slide rail, the vertically movable sleeve of the slide rail is connected with a movable clip seat, and a screw fixed arm is installed at the lower end. The train wheel spreader provided by the invention can be used on different types of wheels through simple adjustment, adapts to changes in the shape and size of the wheels, and is used for hoisting train wheels of different shapes and sizes. The connection mode between the parts of the spreader is relatively coordinated, the operation is simple, and the wheels are convenient and easy to circulate in the process. The contact area with the hoisted parts is large, the spreader is clamped firmly, and the wheel will not be damaged after clamping.

Description

technical field [0001] The invention relates to a wheel spreader, in particular to a train wheel spreader, and belongs to the technical field of mechanical equipment lifting devices. Background technique [0002] During the processing of train wheels, it is necessary to clamp, lift, place, and loosen the wheels, and then repeat the clamping and lifting work. Due to the high safety performance requirements of train wheels, during the production, processing, press-fitting and use of wheels The requirements for the wheels are very strict. In order to meet the clamping requirements of the machine tool, realize the normal circulation of the wheels in the process, and prevent the workpiece from being bumped and damaged, it is necessary to configure the corresponding spreader. [0003] The train wheel spreader adopted in the prior art has a structure that the lifting claws are respectively fixed on the same main shaft with a pin shaft, and each lifting claw can rotate freely aroun...

AI Technical Summary

Problems solved by technology

The spreader can only be used for a specific type of train wheel, and cannot be adapted to different types of wheels. The connection mode between the parts is not coordinated, and the contact area with the suspended part is small, which often causes quality problems on the surface of the workpiece, and also There are security risks

[0004] On the whole, the train wheel spreader of the prior art mainly has the following defects: the one, the design of the train wheel is constantly changing, and the existing train wheel spreader can only be used for specific types of train wheels and cannot adapt to Different types of wheels cannot adapt to changes in the shape and size of the wheels; second, the spreader is cumbersome to operate, and the wheels are difficult to circulate in the process; third, the contact area with the suspended parts is small, and the spreader is not clamped firmly. Forced clamping can lead to wheel damage
