Description

Crane steel wire rope anti-loosening detection device Technical Field The utility model belongs to the technical field of crane safety detection, and particularly relates to a crane steel wire rope anti-loosening detection device. Background In the operation of the hoisting device, the wire rope is used as a key component for bearing and transmitting force, and the tensioning state of the wire rope is directly related to the safety and stability of the hoisting operation. Especially under the use scene of repeatedly lifting and frequently hoisting, the wire rope can be loosened with the pulley due to reasons such as abrasion, slipping or rope winding angle change, and further the unstable operation of equipment is caused, and even hoisting accidents occur. Therefore, in the operation process of the crane, the real-time detection of the loosening state of the steel wire rope is of great significance. The existing crane steel wire rope monitoring device mostly uses a tension sensor or a photoelectric switch as a core, is usually arranged between a steel wire rope and a winding drum, is mainly used for monitoring overall tension change, and is difficult to sensitively detect local loosening conditions at two ends of a pulley. Especially, under the structure that a plurality of pulleys are connected in parallel at certain hanging points, although the steel wire rope is in a tensioning state, slight bulge or external support deformation can occur at the positions of the pulleys at two ends of the steel wire rope, and the traditional device cannot effectively recognize the deformation. In addition, part of the existing schemes have complex structures, are difficult to debug, lack an intuitive alarm feedback mechanism, and are not beneficial to quick judgment and response of on-site staff.
