Description

Crane wheel durable wear test device and method Technical Field The invention relates to the field of quay crane, in particular to a crane wheel durable wear test device and method. Background Crane wheels are a core component of the crane's operating components, and their interaction with the rail directly affects the crane's performance and safety. The performance detection of the wheels is mainly realized through static load tests and dynamic load tests. The static load test is used for testing the bearing capacity of the wheel in a static state, and the dynamic load test needs to simulate dynamic behaviors such as abrasion, fatigue and the like of the wheel in actual work, so that the dynamic load test is a key means for evaluating the durability of the wheel. At present, the mainstream dynamic load test method is to manufacture a simulated experiment crane, and lay a track on a special field to make the track run reciprocally according to a preset working condition, so as to obtain performance data of wheels in a moving state. However, this test method based on complete machine simulation has the following obvious drawbacks: First, the test is costly and environmentally poorly adaptable. The special experimental crane and the long-distance track field are built, so that not only is the initial investment huge, but also the large-area land resources are occupied for a long time. In addition, the test field arranged in the open is extremely easily influenced by weather conditions such as rain, snow, sand, and the like, so that the test process is interrupted or the data consistency is poor, and the continuity and stability of data acquisition are difficult to ensure. Second, test load adjustment is difficult. The wheel pressure of the experimental crane mainly depends on inherent factors such as the self hoisting weight and the weight of the whole crane, and cannot be flexibly adjusted according to the test requirements, so that the stress states of wheels under different load working conditions are difficult to simulate. Meanwhile, with increasing demands of crane users on the accuracy of key component data, especially aiming at attention of core data such as wheel abrasion life and the like, the traditional simulation test mode is difficult to meet market demands.
