Anti-rotation positioning device for lifting hook

Abstract

The invention relates to a positioning device, in particular to an anti-rotation positioning device for a lifting hook. According to the anti-rotation positioning device for the lifting hook, the state of the lifting hook can be automatically adjusted when cargoes are lifted and put down, and the cargoes can be hooked conveniently. According to the technical scheme, the anti-rotation positioning device for the lifting hook comprises a connecting seat, a connecting plate, a bearing seat, a driving shaft, a first pressure plate, a second pressure plate and the like, two connecting plates are symmetrically and fixedly connected to the connecting base, a bearing base is fixedly connected to the two connecting plates jointly, a driving shaft is rotationally connected to the bearing base, a first pressing disc is fixedly connected to the driving shaft, a second pressing disc is connected to the driving shaft, and the driving shaft is sleeved with a reset spring used for pushing the first pressing disc and the second pressing disc to reset upwards. Through cooperation of the lifting hook, the connecting block, the limiting mechanism, the limiting groove and the hexagonal prism, the defects that in the prior art, the state of the lifting hook cannot be automatically adjusted when goods are lifted and put down, and the adjusting efficiency is low 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 the most common type of spreader in the 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 rotating connection, and the hook can swing, and the hook can be rotated by rotating the hook. The position where the goods are located, the swinging hook is convenient for the hook to hook the goods; but when the rotating hook is lifting the goods, because some goods are heavy or large in size, it is easy to drive the hoist during the moving process. The hook rotates, causing the cargo to be unstable during transportation, and it is easy to cause the cargo to collide with the surrounding facilities, or even injure the staff, which makes the lifting operation, which already has a certain...

Problems solved by technology

[0006] In order to overcome the fact that the hook in the prior art cannot automatically adjust the state of the hook when lifting and lowering the goods, the efficiency of the adjustment is low, and when the volume of the goods is large The disadvantages of inconvenient adjustment and inconvenient hooking of goods, the technical problem is: to 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
