Device capable of quickly fixing travelling crane lifting hook

Abstract

The invention provides a device capable of quickly fixing a travelling crane lifting hook and overcomes the technical problem that the current device capable of quickly fixing the travelling crane lifting hook is time-consuming and labor-consuming in disassembly and assembly. The device capable of quickly fixing the travelling crane lifting hook comprises a U-shaped plate, two vertical plates and a semicircular annular plate, wherein the lower ends of the two vertical plates are fixedly connected with the U-shaped plate respectively; the two vertical plates are respectively perpendicular to the plane of the U-shaped plate; the upper ends of the two vertical plates are fixedly connected with two ends of the semicircular annular plate; a second semicircular hole matched with a first semicircular hole of the semicircular annular plate is formed in the middle part of the upper side of each vertical plate; the first semicircular holes and the second semicircular holes are combined to form a circular hole; first plug pin holes are respectively formed in the two vertical plates; plug pins are held in the first plug pin holes. The device capable of quickly fixing the travelling crane lifting hook is simple and practical in structure, and is safe and efficient, and has time-saving and labor-saving effects; when the device is an electric and rotary clamp equipped for the travelling crane, the travelling crane lifting hook can be reliably located by the plug pins; when molds are allocated and transported by the travelling crane, the travelling crane lifting hook can freely rotate; and the two manners can be quickly converted.

Description

technical field [0001] The invention relates to a fast fixing device for a driving hook in the hoisting field. Background technique [0002] At present, the crane equipped with electric rotatable electric clamps requires that the hook can be reliably positioned when the crane lifts the steel coil, and the rotation is not allowed, and the positioning device is used to ensure that the hook does not rotate; when the crane is transferred or the mold is turned over, the crane hook is required to be able to wind around the vertical line. The axis rotates freely. By installing or removing the hook fixing device, the rotation or fixing of the hook is realized. It takes 2 people 10-20 minutes for each replacement. Frequent disassembly and installation are time-consuming and laborious. This requires improving the positioning device to reduce Labor intensity, reduce replacement time, improve work efficiency. Contents of the invention [0003] The purpose of the present invention is ...
