Description

Technical Field

[0001] The utility model relates to the technical field of traction beam disassembly and assembly, in particular to overall replacement equipment for traction beams of CRH5A type EMU bogies. Background Art

[0002] When the traction beam of the CRH5A EMU bogie is replaced as a whole, the traction beam is usually jacked up, and maintenance personnel enter the bottom of the traction beam to remove the bolts on the traction beam one by one. The narrow space for movement will increase the difficulty of disassembling and assembling the traction beam, and extend the working time of disassembling and assembling the traction beam.

[0003] In view of the above problems, we propose the overall replacement equipment for the traction beam of the CRH5A EMU bogie. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The equipment for replacing the traction beam of the bogie of CRH5A EMU includes:

[0007] Shipping seat plate, support frame, hydraulic cylinder and inverted cone tooling;

[0008] The bottom of the shipping seat is connected to a plurality of supporting rollers;

[0009] The support frame comprises a support frame, two support rods are connected to both sides of the support frame, and a plurality of fixing rods are fixed inside the support frame.

[0010] Preferably, the bottom of the support rod and the support frame are connected to the shipping seat plate with a plurality of fixing bolts, and the support frame and the support rod are fixed to the shipping seat plate by the plurality of bolts.

[0011] Preferably, the support frame and the top of the support rod are connected with mounting bolts, and the support frame and the top of the support rod are fixed by the mounting bolts.

[0012] Preferably, the outer sleeve of the hydraulic cylinder is provided with a plurality of clamps, and the clamps are in a "U"-shaped structure.

[0013] Preferably, locking nuts are sleeved on both ends of the clamp passing through the interior of the fixing rod.

[0014] Preferably, the hydraulic cylinder and the support frame are mounted via a plurality of clamps.

[0015] Preferably, the hydraulic cylinder and the inverted cone tooling are fixed by bolts.

[0016] Preferably, a handle frame is fixed above the shipping seat plate by bolts.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model can dismantle the traction beam. The use of the equipment can avoid people from using hand-supported traction beams and tools, which can not only solve the problem of uncoordinated manual strength, but also greatly ensure the safety hazards caused by workers standing under the traction beam during operation.
