Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of lifting appliance structures, in particular to a kind of open wagon side door lifting appliance. BACKGROUND

[0002] As an important tool for freight transport, the opening and closing of the side door of railway open wagon is very important, and it is a must-check point for vehicle body maintenance. During the maintenance process of the side door of open wagon, it needs to be disassembled from the vehicle body, and then installed back to the original position after maintenance. The lifting process of disassembly and installation of the side door of open wagon uses chain hook, and relies on manual and overhead crane to cooperate with operation. This method not only consumes time and effort, but also has safety hazards in the disassembly process. Therefore, it is particularly important to design a safe and reliable side door lifting appliance. SUMMARY

[0003] The utility model aims at providing a kind of open wagon side door lifting appliance. The lifting appliance can prevent chain unhooking problem in the lifting process of side door, and ensure the safety of employees.

[0004] The technical scheme of the utility model: a kind of open wagon side door lifting appliance, including insertion pin, the middle surface of insertion pin is fixedly connected with mounting plate, and both form T-shaped structure, one chain is installed on the both sides of mounting plate, two chains are sliding door chain and lock door chain respectively, and the end of two chains is equipped with lifting ring.

[0005] In the foregoing open wagon side door lifting appliance, the mounting plate is also provided with a handrail.

[0006] In the foregoing open wagon side door lifting appliance, the insertion pin is T-shaped structure.

[0007] The utility model has the advantages that compared with prior art, the utility model can prevent chain unhooking problem in the lifting process of side door, and ensure the safety of employees. The lifting appliance has simple structure, is convenient to use, and is compatible with the lifting requirements of sliding door and lock door, with high working efficiency. Moreover, the lifting process is stable, and effectively reduces the safety risk in operation process. BRIEF DESCRIPTION OF DRAWINGS

[0012] The utility model will be further explained in connection with the drawings and examples, but not as the basis for limiting the utility model.

[0013] The utility model discloses an open wagon side opening door lifting appliance, including insert pin 1, the middle surface fixed connection of insert pin 1 has mounting plate 2, and both form T character type structure, and one chain is installed on the both sides of mounting plate 2, and two chains are sliding door chain 3 and lock door chain 4 respectively, and the end of two chains is equipped with the lifting ring 5.

[0014] The open wagon side opening door is divided into two kinds of structures of sliding door and lock door, and the open wagon side opening door surface is provided with annular recess, and the recess has certain depth, and the recess at the close outside of open wagon side opening door is welded with the backing plate, and the backing plate is welded and fixed with the side door hinge leaf. With the lifting sliding door as an example, the lifting ring 5 of sliding door chain 3 is connected with the crown hook, the insert pin 1 of sliding door chain 3 one side is inserted into the recess below the side door hinge leaf backing plate, and the lifting appliance is made to resist the side door hinge leaf backing plate, then the open wagon side opening door can be separated from the car body using the crown.

[0015] The handrail 6 is also installed on the mounting plate 2, which facilitates the carrying of the lifting appliance.

[0016] The insert pin 1 is T character type structure, the open wagon side opening door surface is provided with annular recess, and the recess has certain depth, after the T character type structure insert pin 1 is inserted into the recess, the mutual movable space between insert pin 1 and open wagon side opening door is small, guarantees that the open wagon side opening door does not shake during the lifting of open wagon side opening door, and the stability is good.

[0017] The lifting appliance of the utility model can improve work efficiency, and the lifting appliance has high adaptability (can respectively lift sliding door and lock door), is simple and convenient to use, and can be inserted; the lifting process is stable, and effectively reduces the safety risk in the operation process.
