Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment, and in particular to a railcar locking flaw detector support frame. Background Technology
[0002] In modern automated testing systems, flaw detector support frames are a crucial testing component widely used in various contact tests. The design of flaw detector support frames must meet the requirements of high precision, high stability, and ease of operation to adapt to the needs of different testing scenarios. Traditional flaw detector support frames are typically positioned and fixed manually or through simple mechanical structures. This method often suffers from insufficient locking force, inaccurate positioning, and complex operation when dealing with high-precision test objects such as rails. As a critical component of transportation systems, the quality of welding and the absence of hidden defects in rails are crucial for ensuring safe operation. Therefore, when testing railcars, a flaw detector support frame that can stably and reliably lock the railcar is needed to ensure accurate contact between the probe and the test point. While some flaw detector support frame designs exist for large test objects, these designs are often complex in structure, expensive, and limited in application, mostly only suitable for use with one or more probes on the same horizontal plane, making them unsuitable for use with objects like rails that have specific shapes and functions. Therefore, in order to solve the above problems, it is necessary to optimize the structure of the flaw detector support frame to improve its overall performance and application range.
