Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings.

[0015] like figure 1 As shown, a crane hook anti-decoupling device according to the present invention includes a hook, a chute is processed on the hook, a spring and a slider are installed in the chute, there is a groove on the slider, and there is a circle above the groove The hole is used to fix the thin steel wire rope. The thin steel wire rope is used to connect the slider to the arc connecting rod. The connecting rod also has a round hole for fixing the thin steel wire rope. The other end of the connecting rod is fixed on the pin shaft to realize rotation.

[0016] like figure 2 As shown, the buckle has a built-in spring, and is connected with the connecting rod through the rotating shaft, and the connecting rod is connected with one end of the lever through the rota...

Abstract

The invention discloses an anti-unhooking device for a crane hook. According to the anti-unhooking device for the crane hook, a sliding groove is formed in a straight handle of the hook, a spring I and a sliding block are installed in the sliding groove, the sliding block is a straight rod with a rectangular section, a concave groove is formed in the lower end of the straight rod, a telescopic buckle is arranged on the inner side of the hook, a spring II is arranged in the buckle for supporting, an unhooking button is arranged on the outer side of the hook, the hook is provided with an arc-shaped connecting rod, and the tail end of the connecting rod is connected to the straight rod through a thin steel wire rope. The anti-unhooking device for the crane hook has the advantages that when a lifting rope is hung into the hook, the hook can be automatically closed, so that the lifting rope cannot slide off, and the safety of lifting work is ensured; and when lifting is finished and the lifting rope is taken down, the unhooking button is pressed down, so that the lifting rope can be quickly taken down, and therefore the working efficiency is high, and convenience and rapidness are achieved.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, in particular to an anti-decoupling device for a crane hook. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and transports heavy objects horizontally within a certain range. Its work is characterized by intermittent movements, that is, the corresponding mechanisms for retrieving, moving, and unloading in a working cycle work alternately. of. [0003] Cranes are common operating equipment in large-scale projects and play an important role. Once a safety accident occurs, it will cause serious consequences. During the hoisting operation of the crane, there is a possibility that the sling may fall off from the hook, thereby causing property damage and even casualties. In order to ensure the safety of the operation, a crane hook anti-decoupling device is proposed now. Contents of the invention [0004] Purpose of the invention: the...
