[0001] The utility model relates to the technical field of parts testing, in particular to a locomotive traction connecting piece strength testing structure. Background Art

[0002] As we all know, during the operation of railway locomotives, traction connectors bear the key mission of transmitting huge traction force. Their strength is directly related to the safety and reliability of train operation. The locomotive traction connector strength test structure is an important facility specifically used to evaluate the mechanical properties of such connectors. It is usually composed of a loading system, a measuring system, a fixing device and other parts. The loading system can simulate the traction loading conditions in the actual operation of the locomotive. The measuring system accurately monitors key data such as stress and strain of the connector during the force process. The fixing device ensures that the connector is in a stable state during the test. Through this test structure, it can effectively detect whether the traction connector meets the design strength requirements, providing a strong guarantee for the safe and stable operation of railway locomotives.

[0003] Existing equipment often only has one function, that is, it can only test one of the bending strength and torsional strength of the connector. This requires workers to prepare at least two machines, which not only increases the cost of the equipment, but also takes up more space.

[0004] The existing patent (publication number: CN215492905U) discloses a connector strength testing device, including a rectangular workbench, four bases, a connecting shaft with a rectangular cross-section, a column, a vise, a column, a connecting shaft with a circular cross-section, a drive wheel, a drive belt, a vise, a drive wheel, a torque sensor, a rotating shaft, three bearing seats, a reduction gear, a motor and a motor base; this utility model has the advantages of flexible use, and therefore can be widely used in the field of mold engineering.

[0005] In response to the above problems, existing patents have provided solutions. However, when conducting strength tests on connectors, due to the lack of a structure for simulating the multi-directional stresses on the connectors during locomotive travel, it is impossible to simulate the strength of the connectors during travel, which reduces the flexibility of testing the strength of locomotive traction connectors.

[0006] Therefore, a locomotive traction connector strength test structure is proposed. Utility Model Content
