Problems solved by technology

To realize and study the anti-sway of the crane, it is necessary to do a good job in the anti-sway design of the mechanical aspect firstly, considering the three aspects of the spreader, cart and trolley; secondly, to do a good job in the design of the electrical aspect, and finally realize the precise control of the device, However, the price of electrical anti-sway is too high, so a lower-priced anti-sway device for lifting equipment will have a good market prospect
[0003] In view of the above problems, the existing patent publication number CN207330161U discloses an anti-sway device, but this device exists only by adjusting the angle of the hook so that the weight slides to one side of the hook. limited effect

Embodiment 1

[0020] see Figure 1~3 , in an embodiment of the present invention, an anti-sway device for lifting equipment includes a body 1, a suspension ring 5 is provided at the upper end of the body 1, and the suspension ring 5 is used to connect a lifting mechanism, and a boom 2 is provided at the lower left end of the body 1, and the boom 2 is provided at the lower left end of the body 1. 2. The lower right side is connected with the hook 4 through the connecting block 3. The hook 4 is in the shape of a semicircle. The body 1 above the hook 4 is provided with a pressing mechanism, and the hanging point of the heavy object is pressed tightly on the hook 4 through the pressing mechanism. , so as to avoid the shaking problem.

[0021] The pressing mechanism includes a sliding cavity 20 positioned at the lower end of the body 1, a sliding block 9 is slidably fitted in the sliding cavity 20, a limiting mechanism is arranged between the sliding block 9 and the sliding cavity 20, and the li...

Embodiment 2

[0027] Described hook 4 is also provided with anti-off mechanism, and anti-off mechanism comprises telescopic cavity 22 that is positioned at hook 4 ends, and telescopic rod 16 is slidably fitted in telescopic cavity 22, and telescopic rod 16 lower end is connected with the bottom of telescopic cavity 22 by reset spring 17. Connect and fix, the upper left side of the telescopic chamber 22 is provided with a traction hole, the lower left side of the telescopic rod 16 is tied with a wire rope 18, the wire rope 18 passes through the traction hole, and is connected and fixed with the upper left side of the hook 4, when no heavy objects are suspended, Under the action of the return spring 17, the telescopic rod 16 is received inside the telescopic cavity 22. When hanging heavy objects, under the action of gravity, the steel wire rope 18 is pressed down. 22 rises, thereby prevents heavy object from breaking away from hook 4, has improved the safety of device further.

Abstract

The invention discloses a shake prevention device for hoisting equipment. The device comprises a body; a hand ring which is used for connecting a hoisting mechanism is arranged at the upper end of thebody; a suspender is arranged at the left lower end of the body; the hook which is semi-circular is connected with the lower side of the suspender through a connection block; a compression mechanismis arranged on the body above the hook; and a weight suspension point is pressed on the hook through the compression mechanism, so that the problem of swinging is avoided and then strong practicability is provided.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to an anti-sway device for lifting equipment. Background technique [0002] A good crane anti-sway device can avoid a series of accidents such as collisions, and greatly improve the operating efficiency of the crane and the safety of the crane operation process. To realize and study the anti-sway of the crane, it is necessary to do a good job in the anti-sway design of the mechanical aspect firstly, considering the three aspects of the spreader, cart and trolley; secondly, to do a good job in the design of the electrical aspect, and finally realize the precise control of the device, But the electric anti-sway price is too high, therefore, a kind of lifting equipment anti-sway device with lower price will have a good market prospect. [0003] In view of the above problems, the existing patent publication number CN207330161U discloses an anti-sway device, but this device ex...
