Description

Technical Field

[0001] This application relates to the field of testing tooling technology, such as a coupler support seat jamming testing tooling. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] The coupler and buffer device is an important component of a rolling stock. Its function is to securely connect the locomotive and rolling stock, and between rolling stock themselves, while maintaining a certain distance between them, thus transmitting and mitigating the longitudinal traction and impact forces generated during train operation or shunting. When a rolling stock enters the depot or undergoes factory maintenance, the coupler and buffer device is periodically inspected along with the entire rolling stock. The purpose of this inspection is to restore its original design performance and ensure that all components and their clearances are within specified limits, guaranteeing that the entire rolling stock functions properly before its next scheduled maintenance, thereby ensuring railway transportation safety.

[0004] Currently, the tools used for coupler support seat jamming tests are a two-meter-long crowbar and a one-ton small hydraulic jackhammer. When using the two-meter crowbar for jamming tests on temporary repair vehicles, it is easy for the crowbar to slip when pressed down, making it difficult to guarantee personal safety. When using the one-ton hydraulic jackhammer for jamming tests on section repair vehicles, repeated pressing operations are required, which is cumbersome, time-consuming, and labor-intensive. In addition, the inner side of the top of the impact seat is designed with a certain slope, and the head of the hydraulic jackhammer is easy to slip when pressed down, posing a certain safety risk. Summary of the Invention

[0005] This application provides a fixture for testing the jamming of a coupler support seat. The base and top plate significantly increase the contact area, preventing slippage. The axial limiting design of the guide rod and floating top rod eliminates the risk of lateral slippage associated with traditional pry bars. During the test, the direction of force applied is precisely matched to the movement trajectory of the coupler support seat. The operating handle allows for a single downward stroke to meet the test requirements, greatly improving operating efficiency compared to a hydraulic pick. The fixture is lightweight, simple in structure, and easy to learn; it can be operated independently by a single person, saving time and effort; the operation is absolutely safe and fully meets the requirements for on-site support seat jamming tests.
