Steel wire rope detection device for crane

The invention relates to the field of detection devices, in particular to a steel wire rope detection device for a crane. Comprising a base, a first mounting plate is fixed to the upper end of the base, a conduction assembly is slidably arranged on the first mounting plate, a pressing block is fixed to the lower end of the conduction assembly, a groove corresponding to the pressing block is formed in the base, and a pressure sensor is fixed in the groove; a clamping rotating device is slidably arranged in the vertical direction of the cleaning cylinder and fixed to the upper end of the conduction assembly, a deoiling solvent spraying assembly is elastically and rotatably arranged in the cleaning cylinder, and the clamping rotating device is allowed to drive the deoiling solvent spraying assembly to rotate intermittently in the rotating process. In the oil removal process of a steel wire rope sample, the steel wire rope can rotate in the direction opposite to the winding direction of the steel wire rope, then
