Abstract

A kind of suspension hook that can voluntarily break off relations with lifting cargo, belongs to hoisting sling technical field, for can voluntarily separate with lifting cargo after lifting in place.Its technical solution is: suspension hook plate is elongate steel plate, the lower end of suspension hook plate is connected with crotch, and the connecting portion of suspension hook plate and crotch has lifting hole(eyelet), and suspension hook wirerope is through in lifting hole(eyelet), suspension hook wirerope is connected with the suspender of overhead traveling crane or crane, and the weight of suspension hook plate is greater than the weight of crotch.Behind the main lifting cargo in-position of the utility model, the crotch of suspension hook and the lifting wirerope of lifting cargo loosen, since the weight of suspension hook plate is greater than the weight of crotch, suspension hook can be fulcrum to one side to overturn of suspension hook plate using lifting hole(eyelet), crotch becomes laterally, and the wirerope under the cooperation of overhead traveling crane or crane automatically with lifting cargo is detached from.The utility model is ingenious in design, structure is simple, easy to use, and the decoupling device job step of staff is omitted, and so as to reduce staff, reduces labor intensity, improves production efficiency.

Description

A hook that can be decoupled from the hoisted cargo by itself

technical field

The utility model relates to a hook which can be separated from the hoisted goods by itself after being hoisted in place, and belongs to the technical field of hoisting slings.

Background technique

In factories, stations, docks, freight yards, freight stations and other places, a large number of lifting equipment undertake heavy lifting work. Generally speaking, when cranes or cranes are hoisting objects, the work of hanging and removing the hooks is required manually. With the development of production, the hoisting work of many enterprises is busy. Cranes and cranes have to carry out frequent hoisting operations, and each hoisting requires manual hooking and unhooking, which takes up a large number of operators. At the same time, the labor intensity of workers Very large, reducing productivity.

Utility model content

The technical problem to be solved by the utility model is to provide a hook that can be decoupled from the hoisted goods by itself. This kind of hook can be unhooked by itself after the hung goods reach the destination, thereby improving work efficiency and reducing operators.

The technical scheme that solves the above-mentioned technical problem is:

A hook that can be decoupled from the hoisted cargo by itself, which includes a hook plate, a curved hook, a hanging hole, and a hook wire rope. The hook plate is a long steel plate, and the lower end of the hook plate is connected with the hook. There is a lifting hole at the connecting part of the plate and the hook, and the hook wire rope is passed through the lifting hole. The hook wire rope is connected with the crown block or the spreader of the crane, and the weight of the hook plate is greater than that of the hook.

The above-mentioned hook that can be decoupled from the hoisted cargo by itself, the thickness of the steel plate of the hook plate is 30-60mm, the upper end of the hook plate is arc-shaped, and the side of the hook plate opposite to the opening of the hook is a smooth curve. The opposite side of the hook plate to the back of the crotch is a straight line.

The above-mentioned hook that can be decoupled from the hoisted cargo by itself, the hook is made of the same steel plate as the hook plate, and the outer circumference of the hook tip, hook body and hook tail is a smoothly connected circular arc.

The beneficial effects of the utility model are:

The top of the crotch hook of the utility model connects the hook plate, the weight of the hook plate is greater than the weight of the crotch, and the hook wire rope is worn in the hanging hole, and the hook wire rope is connected with the crane or the sling of the crane. After the hoisted goods arrive at the position, the hook of the hook and the hoisting wire rope of the hoisted goods are loosened. Since the weight of the hook plate is greater than that of the hook, and the center of gravity of the hook is located on the side of the hook plate, the hook will take the lifting hole as the fulcrum Turn over to the side of the hook plate, the hook becomes horizontal, and automatically separates from the wire rope for lifting the cargo with the cooperation of the crane or the crane.

The utility model is ingenious in design, simple in structure and convenient in use. After the hoisted goods are in place, they can be flipped and unhooked by themselves, omitting the steps of unhooking operations by staff, thereby reducing the number of staff, reducing the labor intensity of staff, and improving production efficiency.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a schematic diagram of the use state of the utility model.

The marks in the figure are as follows: hook plate 1, crotch 2, hoisting hole 3, hook wire rope 4, hoisting wire rope 5, sling 6.

Detailed ways

The utility model is made up of suspension hook plate 1, crotch 2, suspension hole 3, suspension hook wire rope 4.

As shown in the figure, the hook plate 1 is a long steel plate, and the lower end of the hook plate 1 is connected with the crotch 2 . The thickness of the steel plate of the hook plate 1 is 30-60mm. The hook plate 1 is designed in a curved shape, which is convenient for self-extraction. The upper end of the hook plate 1 is arc-shaped. Smooth curve, the opposite side of the hook plate 1 and the back of the crotch 2 is a straight line.

The figure shows that the crotch 2 is made of the same steel plate as the hook plate 1, and the outer circumferences of the hook point, the hook body and the hook tail of the crotch 2 are arc-shaped smoothly connected. The weight of the hook plate 1 is greater than that of the crotch 2.

Shown in the figure, the hook plate 1 and crotch 2 connecting parts have lifting holes 3, and the lifting hook wire rope 4 is passed in the lifting hole 3, and during hoisting, the lifting hook wire rope 4 is connected with the spreader 6 of crown block or crane.

Shown in the figure, when carrying out hoisting operation, need manually carry out hooking, crotch 2 is hooked up hoisting wire rope 5. After the hook wire rope 4 is connected with the crown block or the crane spreader 6, the crown block or the crane spreader 6 rises, the hook wire rope 4 lifts the hook through the lifting hole 3, and the hook 2 at the lower part of the hook bears the weight of the cargo , so the crotch 2 rotates to the normal hoisting position, and the crotch 2 carries out the hoisting operation below the hook plate 1.

The figure shows that if the hook 2 is in the no-load state, since the weight of the hook plate 1 is greater than that of the hook 2, the hook will turn over to the side of the hook plate 1 with the lifting hole 3 as the fulcrum, and the hook 2 will become For horizontal, reach the purpose that suspension hook breaks away from hoisting wire rope 5.

The figure shows that after the hoisted goods arrive at the position, the crane or the crane performs the hook drop operation. As the hoisted objects touch the placement surface, the hooks continue to drop. The hook 2 of the hook and the hoisting wire rope 5 of the hoisted goods are loosened. The weight of the plate 1 is greater than the weight of the hook 2, the hook will turn over to the side of the hook plate 1 with the lifting hole 3 as the fulcrum, the hook 2 becomes horizontal, and automatically rotates until the opening of the hook 2 is opposite to the hoisting wire rope 5 , the spreader 6 of mobile overhead crane or crane, drives suspension hook to the reverse movement of crotch 2, and crotch 2 of suspension hook can break away from hoisting wire rope 5, finishes the action of unhooking automatically.
