Description
Technical field
The utility model belongs to technical field of crane equipment, is specifically related to a kind of crane hook anti-rotation positioning device.
Background technology
The suspension hook group of hoisting crane has traditional and two kinds, grasp type, traditional suspension hook group is a kind of suspension hook comparatively commonly used, when hoisting heavy, because of center of gravity or the steel rope inclination of weight, after lifted weight thing leaves ground, hoisting heavy can be caused ceaselessly to rotate along with the rotation of suspension hook group, easy generation is collided with, even cause potential safety hazard, in order to overcome above-mentioned Problems existing, prior art adopts and is provided with location anchor ear in hook neck position, the anti-rotation locating effect of suspension hook group is reached by folding and unfolding latch, although this technology overcomes the problem that suspension hook group rotates, but this machinery location anti-rotation device price is high, significantly add use cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides the crane hook anti-rotation positioning device that a kind of structure is simple, esy to use, safe and reliable, cost performance is high.
The purpose of this utility model is achieved in that a kind of crane hook anti-rotation positioning device, it comprises lifting plate, described lifting plate middle position is provided with through hole, the lower inside of described lifting plate is provided with crossbeam, described crossbeam is connected with hook body, and described hook body top is provided with raceway groove, is provided with groove above described raceway groove, be connected with bearing pin outside described groove, between described bearing pin and lifting plate, be connected with spring.
The shape of described through hole is circular.
The shape of described groove and the matching form of bearing pin close.
The structure of described bearing pin is middle thin, the structure that two ends are thick.
The two ends of described spring respectively with bearing pin, lift plate and fixedly weld.
The beneficial effects of the utility model: the utility model adopts symmetrical structure, groove is provided with in hook body both sides, two grooves are all connected with bearing pin, compact conformation, effectively make use of the inner space of lifting plate, self function and the aesthetic measure of lifting plate is not affected after installation, this device is easily manufactured, can be mass, use this device, the relatively whole project of its cost of manufacture can be ignored, there is higher economic benefit, this suspension hook anti-rotation positioning device, after installing, make bearing pin alignment indentation, just anti-rotating function can be realized, when needs suspension hook rotates, extract two bearing pins simultaneously, it is simple that total the utility model has structure, easy to use, safe and reliable, the advantage that cost performance is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of crane hook anti-rotation positioning device of the utility model.
