Description

Technical Field

[0001] The utility model relates to the field of rail detection, in particular to a visual detection device for heavy rails of a bridge crane. Background Art

[0002] Bridge crane rails are fixed to steel track beams via rail clamps, providing continuity, stability, and safety for supporting and guiding the wheels. During the production process of heavy-duty foundry cranes lifting ladles of molten iron and steel in steel mills, the rails are susceptible to metal fatigue, resulting in weakened strength and fatigue cracking due to numerous factors, such as large fluctuations in lifting loads, high operating speeds, frequent use, and structural elastic deformation. This presents a significant safety hazard during the operation of heavy-duty foundry cranes. The crane rails' placement along the centerline of the steel structure's flanges, harsh environmental conditions, and proximity to overhead structures make routine inspections difficult, hindering the timely detection and elimination of dangerous cracks in the rails. These challenges primarily arise from the following: First, the unique design and installation location of the rails limit routine inspections to the top and right side of the rail, with the left and underside surfaces consistently overlooked. Second, cracks have repeatedly been concentrated on the underside of the rail, requiring inspectors to squat or lie prone to inspect the abnormality there. The cracks then rapidly develop, posing a significant safety hazard. The third difficulty is that the factory has complex and harsh environmental conditions such as insufficient light, high altitude, and heat waves. The inspectors are inefficient and cannot detect the occurrence and development of rail cracks in time, which brings major safety risks to the safe operation of the casting crane.

[0003] If such difficult problems can be effectively solved, it will not only allow equipment inspectors to detect track cracks in advance during daily equipment inspections, especially cracks on the left side and lower side rails, so that they can be discovered and dealt with in a timely manner, preventing equipment safety hazards caused by rail cracks and affecting safe production; it will also effectively reduce the increased labor intensity caused by factors such as long-term bending and tilting of the head, and indirectly play a role in preventing occupational diseases. In view of the many problems and safety hazards mentioned above, it is necessary to develop a visual inspection device for heavy-duty rails specifically for bridge cranes. Utility Model Content
