A hook anti-rotation positioning device

Abstract

The invention relates to a positioning device, in particular to a hook anti-rotation positioning device. The technical problem is: to provide a hook anti-rotation positioning device that can automatically adjust the hook state when lifting and laying down the goods, and is convenient for hooking the goods. The technical scheme is: an anti-rotation positioning device for a hook, comprising a connecting seat, a connecting plate, a bearing seat, a driving shaft, a first pressing plate, a second pressing plate, etc.; two connecting plates are symmetrically fixed on the connecting seat , the two connecting plates are jointly fixed with a bearing seat, the bearing seat is rotatably connected with a driving shaft, a first pressure plate is fixed on the driving shaft, a second pressure plate is connected on the driving shaft, and a sleeve on the driving shaft is used to push Return springs that return the first pressure plate and the second pressure plate upward. Through the cooperation of the hook, the connecting block, the limiting mechanism, the limiting groove and the hexagonal column, the disadvantages of the prior art, such as the inability of the hook in the prior art to automatically adjust the state of the hook when hoisting and putting down the goods, and the low adjustment efficiency are overcome. .

Description

technical field [0001] The invention relates to a positioning device, in particular to a hook anti-rotation positioning device. Background technique [0002] The hook is one of the most common spreaders in machinery. [0003] In the hoisting operation in the prior art, in order to facilitate the hanging of the goods on the hook, the hook is usually installed on the hoisting machine in a rotational connection, and the hook can swing, and the hook can be rotated by rotating the hook. The position of the quasi-goods, the swinging hook is convenient for the hook to hook the goods; however, when the rotating hook is hoisting the goods, because some goods are heavier or larger, it is easy to drive the hoist during the moving process. The hook rotates, which makes the goods unstable during transportation, which can easily cause the goods to collide with surrounding facilities, or even bruise the staff, which makes the lifting operation with a certain risk factor even more hidden. ...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the shortcomings that the hook in the prior art cannot automatically adjust the state of the hook when lifting and lowering the goods, the adjustment efficiency is low, and it is inconvenient to adjust and hook the goods when the goods are large in size, the technical problem is as follows: : Provide a hook anti-rotation positioning device that can automatically adjust the state of the hook when lifting and lowering the goods, and is convenient for hooking the goods
