Background

The oil pressure vibration absorber is an important vibration attenuation component on a suspension device of a locomotive and a vehicle, achieves the aim of vibration attenuation by forming hydraulic damping force through stretching and compressing a piston rod to reciprocate, has good vibration attenuation damping effect and flexible vibration attenuation effect, and is a key component for improving the stability and the safety of high-speed running of the locomotive and the vehicle.

The oil pressure shock absorber needs to be disassembled and cleaned in the daily locomotive maintenance process, the upper and lower mounting rubber sleeves of the shock absorber need to be taken down during the disassembly, the shock absorber outer cover is disassembled, the joint body locking screw is loosened or the split pin is punched, and the upper joint body is loosened. The screw cap is constructed as shown in fig. 1 and 2, and is fixed on the inner wall of the reserve tube by a screw and pressed on the sealing cap, so that the vibration absorber is placed in a clamp and clamped by a bench clamp, and the screw cap is loosened by a special spanner. And finally, scrubbing the upper joint body, the outer cover, the oil storage cylinder and the gland, cleaning other parts in a special cleaning agent by using a brush, and cleaning all the parts by using compressed air and then reinstalling the parts.

At present, traditional manual wrench is mostly used to oil damper's dismouting, and it is hard to dismantle the in-process, and is difficult for steady loading and unloading, leads to the spiral shell lid to screw up the back, appears that the spiral shell lid exceeds more than oil storage jar 2mm or piston rod and sealed lid and contacts, and it is not right to take place cylinder equipment position, causes inside hydraulic oil to reveal, needs the reassembly this moment.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a wrench for disassembling and assembling a locomotive hydraulic shock absorber, which can solve the problems that the existing device for disassembling and assembling the hydraulic shock absorber mostly uses a traditional manual wrench, is troublesome and labor-consuming in the disassembling process and is not easy to assemble and disassemble stably, so that after a screw cap is screwed down, the screw cap is higher than an oil storage cylinder by more than 2mm or a piston rod is contacted with a sealing cover, the assembling position of a cylinder barrel is not right, and the leakage of internal hydraulic oil is caused to cause the need of reassembly and the like.

In order to solve the problems, the technical scheme of the utility model is as follows: the disassembly and assembly wrench for the locomotive oil pressure shock absorber comprises a working part and a wrench rod part, wherein the working part is formed by welding a wrench working head and a triangular reinforcing plate into a whole; the size and the position of the threaded hole are matched with four screw cap holes on an end cap body of the oil pressure shock absorber, and the threaded hole is matched with the four screw cap holes during working; the reinforcing plate is connected with the trigger lever portion.

In the above technical solution, a more specific solution is: the wrench rod part is made of cylindrical steel materials, the wrench rod part comprises a connecting part connected with the reinforcing plate and a handheld part at the tail end, and grid knurls are processed on the handheld part.

Further: the wrench working head is circular.

Further: the wrench working head is in a half-crescent shape.

Further: the positioning bolt adopts a standard part, and the model specification is M10X40 mm.

Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:

the hydraulic oil damper cylinder assembly comprises a working part and a pull rod part, wherein the pull rod part is made of cylindrical steel, a grid knurling is processed on a holding part at the tail end of the pull rod part, the hydraulic oil damper cylinder assembly is prevented from slipping when a force is applied, two symmetrical threaded holes matched with four holes in an end cover of an oil pressure damper are formed in the working head of a wrench in position, and positioning bolts are assembled in the threaded holes; the maintenance time of workers is greatly reduced, the failure time of the locomotive is invisibly reduced, the transportation efficiency is ensured, the safety environment is improved, and the effect is very good.
