An automatic decoupling device for a crane

Abstract

The invention relates to the technical field of cranes, and discloses an automatic decoupling device for a crane, which comprises a hook, a mounting bracket is sleeved on the top of the hook, and a return spring is fixedly connected to the inner top wall of the mounting bracket. The bottom of the return spring is fixedly connected with a slider, the bottom of the slider is rotatably connected with a connecting rope, the bottom of the connecting rope is rotatably connected with an arc block, the right side of the hook is provided with an anti-dropping rod, the A second connecting block is fixedly connected to the left side of the anti-dropping rod, a movable rod is arranged on the top of the anti-dropping rod, a push rod is rotatably connected to the right side of the mounting frame, and a rotating rod is fixedly connected to the left side of the push rod. piece. By pushing the push rod upward, the push rod drives the rotating block to rotate counterclockwise, so that the rotating block is separated from the movable rod, and the anti-dropping rod slides down to block the opening of the hook, thus achieving the use of the anti-dropping rod to close the opening of the hanging hook. The blocking effect prevents the heavy object from being detached from the hook when it is thrown during the lifting process.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an automatic decoupling device for cranes. Background technique [0002] Crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as cranes, cranes, and aerial cranes. crane. [0003] The current crane generally does not have an anti-decoupling setting when handling heavy objects. When it is transported horizontally, there is a risk of decoupling, which is relatively dangerous, and after the transportation is completed, the workers are generally manually unloading the rope on the heavy object from the hook, which is time-consuming. laborious, so we propose an automatic decoupling device for cranes. SUMMARY OF THE INVENTION [0004] (1) Technical problems solved [0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic decoupling device for a crane,...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic uncoupling device for cranes, which has the advantages of being able to prevent unhooking of heavy objects when carrying heavy objects and automatically unhooking after the end, and solves the problem that the general crane is not equipped and cannot be unhooked when carrying heavy objects. There is a risk of decoupling and after the handling is completed, workers need to manually remove the rope on the heavy object from the hook, which is time-consuming and laborious
