Description

Technical Field

[0001] The utility model relates to the field of engineering machinery, in particular to a boom lateral bending detection device. Background Art

[0002] The crane jib, commonly known as the boom or jib, is a critical load-bearing component. It can be a single section or a nested series of sections. Structural stability is a crucial factor in determining mechanical performance. Instability in the boom structure (for example, severe lateral bending) can easily lead to accidents such as jib breakage and tipping, resulting in serious damage.

[0003] During daily hoisting operations, lateral bending of the boom often occurs, especially in cranes with booms longer than 80 meters. The specific reasons for lateral bending of the boom are: (1) The gap between the sliders of each boom section is too large, which will cause the boom sleeve to swing left and right; or the position of the slider at the head is incorrect, which will cause the boom to deviate to one side. In addition, the current boom is generally multi-section. Once the slider of a certain boom section is not debugged accurately, the lateral bending will be more obvious after the boom is extended; (2) Due to process problems during the manufacturing process of the boom, the boom itself will undergo stress reaction during pressing and welding, which will cause micro-deformation of the boom. Although it cannot be seen with the naked eye, it will cause obvious lateral bending of the boom when assembled on the crane; (3) The skewed docking of the boom tail and the asymmetric gap of the slider at the tail will cause the boom to be deflected under force. Therefore, the hinge shaft and turntable at the boom tail are also prone to lateral bending when installed; (4) For cranes with straight booms, single-section booms, and multi-section booms, structural deformation is also a cause of lateral bending of the boom.

[0004] Therefore, how to accurately detect the lateral bending of the boom is a problem that needs to be solved urgently. Utility Model Content
