Rigging anti-winding device for large crane

Abstract

The invention relates to the technical field of rigging, and discloses a rigging anti-winding device for a large crane. The device comprises two fixing pins corresponding to each other left and right, wherein the back faces of the two fixing pins are fixedly connected with connecting rods, and the ends, away from the fixing pins, of the connecting rods are fixedly connected with transmission cylinders. A hole is formed in the center of the front face of the transmission cylinder, a center shaft is arranged in the hole in a sleeved mode, the center shaft is fixedly connected with the inner wall of the back face of the transmission cylinder, the outer wall, in the transmission cylinder, of the center shaft is fixedly connected with a movable plate, a trapezoidal groove is sectioned in the center of the top face of the movable plate, and a push ball is placed in the trapezoidal groove. By arranging the transmission cylinder, a guide plate is automatically driven to move downwards from the upper portion of a hoisting cable under a centrifugal force effect generated when the crane drives the rigging to move transversely, the hoisting cable is guided by a magnetic force, and shaking of the hoisting cable due to inertia is reduced, so that the probability that the hoisting cables collide with one another and are entangled is greatly reduced, and the working efficiency is improved favorably.

Description

technical field [0001] The invention relates to the technical field of rigging, in particular to an anti-winding device for large-scale crane rigging. Background technique [0002] Crane rigging refers to a complete set of rigging that hooks or grabs the cargo and transmits the pulling force of the hoisting winch to lift and lower the cargo. It generally includes hook devices, blocks, hoisting ropes, and connecting parts such as shackles, eye plates, and collars. [0003] Because most of the goods to be hoisted by the crane are heavy, multiple metal slings are installed on the shackles. Metal slings are usually not entangled due to their heavy weight. , but when the crane drives the rigging to move laterally and then stops, the slings will shake and collide with each other under the action of inertia. Under the collision, there may be problems of entanglement and entanglement, resulting in the failure to hook objects normally and need to be manually Operations such as sepa...

[0003] Because most of the goods to be hoisted by the crane are heavy, multiple metal slings are installed on the shackles. Metal slings are usually not entangled due to their heavy weight. , but when the crane drives the rigging to move laterally and then stops, the slings will shake and collide with each other under the action of inertia. Under the collision, there may be problems of entanglement and entanglement, resulting in the failure to hook objects normally and need to be manually Separation and other operations, reducing work efficiency
