Abstract

The invention relates to the technical field of repairing and maintaining, and specifically relates to a repairing tool for a bracket crane. The repairing tool for the bracket crane comprises a rack,a pulling mechanism, a power mechanism, a straightening mechanism and a shearing mechanism, wherein the pulling mechanism comprises two conveying rollers for conveying a steel wire rope; the conveyingrollers are rotatably connected to the rack; the power mechanism comprises a moving plate, and a mover for driving the moving plate to linearly reciprocate; the straightening mechanism comprises a straightening cylinder, a piston and a piston rod; the shearing mechanism comprises a supporting part and a shearing blade; the shearing blade is fixedly connected to the moving plate; the supporting part is fixed to the rack; the upper surface of the supporting plate and a center line of a second straightening groove are on the same horizontal plane. The repairing tool is capable of automatically straightening and shearing the steel wire rope.

Description

technical field [0001] The invention relates to the technical field of maintenance, in particular to a maintenance tool for a jib crane. Background technique [0002] The jib crane mainly uses the side of the jib to rotate around the vertical axis to cooperate with lifting goods. It is flexible to use and meets the loading and unloading requirements. Its forms include fixed, mobile and floating. The maintenance of the jib crane is a very important link, which affects the service life and safety of the crane. Among them, the strength of the crane wire rope will become smaller as the service time prolongs, and the load-bearing capacity will become weaker. Therefore, it is often necessary to replace the wire rope when repairing the crane. [0003] Most of the wire ropes on the market are wound on the drum, so the wire rope needs to be straightened before using the wire rope. At present, when replacing the wire rope, the most common method is to manually straighten the wire rop...
