[0001] The utility model relates to the technical field of auxiliary disassembly and assembly of a clamp brake unit, in particular to an auxiliary support tooling for a clamp brake unit. Background Art

[0002] When the train undergoes depot repair work, it is necessary to disassemble and install the cylinder of the clamp brake unit. However, the single cylinder body of the clamp brake unit is relatively heavy (100 - 120 KG), and the conventional lifting and disassembly methods cannot be used when disassembling and installing it from the bogie. The following difficulties exist during installation and disassembly:

[0003] 1. The cylinder of the clamp brake unit adopts a top - suspension installation method, and the brake cylinder is designed to be compact, making the hoisting difficult.

[0004] 2. The single cylinder body of the clamp brake unit is heavy. When disassembling by manpower, there is a risk of dropping, and when installing by manpower, it cannot be lifted.

[0005] 3. The parked clamp brake unit cylinder and the motor gearbox are on the same side, and the installation gap is small, so it is easy to interfere with the gearbox during disassembly and installation.

[0006] 4. The bottom of the clamp brake unit cylinder is a clamp guide rod, and the rear part is a clearance adjustment device. The whole is an irregular plane and cannot be stably placed, resulting in easy loss of balance during movement, causing equipment damage or personal injury. Content of the Utility Model

[0007] Aiming at the deficiencies of the above - mentioned prior art, the utility model provides an auxiliary support tooling for a clamp brake unit, which can stably place the cylinder of the clamp brake unit and facilitate the disassembly and installation of the cylinder of the clamp brake unit.

[0022] As Figure 1 and Figure 2 shown, a clamping brake unit auxiliary support tooling includes a fixed frame 1. At the four corners of the bottom of the fixed frame 1, moving wheels 2 are provided. On the fixed frame 1, a support frame 3 is provided. At the top of the support frame 3, a mounting seat 4 for embedding and placing a clamping brake cylinder 5 is provided. The mounting seat 4 is custom-made by copying the bottom of the clamping brake cylinder 5 through 3D scanning.

[0023] The fixed frame 1 is a U-shaped frame, and the support frame 3 is placed in the middle of the U-shaped frame. On the fixed frame 1, a baffle 6 for restricting the movement of the support frame 3 is provided. The baffle 6 includes a set of front and rear baffles arranged on the inner side of the middle of the U-shaped frame. On both sides of the front baffle 601 and the rear baffle 602, a set of left and right side plates 603 are provided. The U-shaped steel frame is provided with a baffle to restrict the movement of the support frame. The support frame is an aluminum alloy seat and is a load-bearing member. When the brake cylinder is stressed on the tooling, the center of gravity is at the center point of the frame. Therefore, there is no need to worry about the risk of the cylinder body falling during the movement. During non-frame repair inspections, when disassembling and assembling a single brake cylinder, the support frame can be separately removed and used in cooperation with a hydraulic trolley, which is not only applicable to the disassembly and assembly of this tooling. The non-fixed design of the support frame 3 and the U-shaped frame facilitates the maintenance of the tooling, and the position can be finely adjusted during use, etc.

[0024] At the rear end of the mounting base 4, there are two first grooves 401 for receiving the fixing bolts at the tail end of the clamp brake cylinder. At the middle and front end of the mounting base 4, there are support parts 402 for receiving two stress points at the lower part of the clamping arm respectively. There is a second groove 403 left in the middle of the mounting base 4 for placing the guide rod. The mounting base 4 is a nylon base and can be completely embedded in the lower part of the brake cylinder. The stress points are two fixing bolts at the tail end of the brake cylinder and four stress points at the lower part of the clamping arm. And a certain clearance is set for the customized nylon base to facilitate the embedding of the brake cylinder.

[0025] The moving wheel 2 is a nylon wheel with a shock-absorbing spring, which can reduce the damage to the tooling to a certain extent when the bogie is lifted and misoperated. When the bogie is accidentally pressed on the tooling, it can buffer to a certain extent to ensure that the tooling does not undergo physical deformation.
