Description

Technical Field

[0001] The invention relates to the technical field of aluminum wire disc hoisting, in particular to a clamping mechanism and a hoisting device. Background Art

[0002] During the production process of aluminum wire reels, the aluminum wire reels need to be lifted by a crane and transported to the designated location. When the crane moves, the aluminum wire reels will swing back and forth with the lifting rope. After the crane moves to the designated location, it is necessary to wait for the aluminum wire reels to return to a stable state before further completing the transportation of the aluminum wire reels. The time waiting for the aluminum wire reels to return to a stable state is relatively long, which seriously affects the production efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a clamping mechanism and a lifting device to solve the problems existing in the above-mentioned prior art and to improve the transportation efficiency of the aluminum wire reel.

[0004] To achieve the above object, the present invention provides the following solutions:

[0005] The present invention provides a clamping mechanism of a lifting device, comprising a limiting sleeve, wherein the limiting sleeve is used to be fixedly arranged below the end of a crane boom, and the limiting sleeve gradually extends from top to bottom in a direction away from the axis of the limiting sleeve. The lifting rope of the crane can lift a wire reel and make the wire reel extend into the limiting sleeve and abut against the inner wall of the limiting sleeve, and the limiting sleeve can limit the movement of the wire reel in the horizontal direction.

[0006] Preferably, a guide plate is fixedly disposed inside the limiting sleeve, and a through hole for passing the suspension rope is formed on the guide plate.

[0007] Preferably, the limit sleeve includes a plurality of limit plates that can be arranged circumferentially around the suspension rope, and each of the limit plates includes a first limit plate unit, a second limit plate unit and an elastic member, one end of the first limit plate unit is used to be fixedly connected to the suspension arm, the other end of the first limit plate unit is fixedly connected to one end of the elastic member, and the other end of the elastic member is fixedly connected to the second limit plate unit.

During the movement of the crane, the wire reel is prevented from shaking back and forth. The crane moves to a designated position, and the wire reel is lowered to complete the transportation of the wire reel. Therefore, the clamping mechanism and lifting device provided by the present invention can improve the transportation efficiency of the aluminum wire reel. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The purpose of the present invention is to provide a clamping mechanism for a lifting device to solve the problems existing in the prior art and to improve the transportation efficiency of aluminum wire reels.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] This embodiment provides a lifting device clamping mechanism 100, such as Figure 1As shown, in this embodiment, a limit sleeve 1 is included, which is used to be fixedly arranged below the end of the crane boom. The limit sleeve 1 gradually extends from top to bottom in a direction away from the axis of the limit sleeve 1. The crane's lifting rope 3 can lift the wire reel and make the wire reel extend into the interior of the limit sleeve 1 and abut against the inner wall of the limit sleeve 1. The limit sleeve 1 can limit the movement of the wire reel in the horizontal direction.

[0021] By arranging a limiting sleeve 1 under the end of the boom, the lifting rope 3 can lift the wire reel upwards and make the wire reel extend into the limiting sleeve 1, so that the wire reel abuts against the inner wall of the limiting sleeve 1 to limit the movement of the wire reel. During the movement of the crane, the wire reel is prevented from shaking back and forth. There is no need to wait for the wire reel to return to a stable state. The crane moves to the specified position and lowers the wire reel to complete the transportation of the wire reel, thereby improving the transportation efficiency.

[0022] A guide plate 2 is fixedly arranged inside the limiting sleeve 1, and a through hole is opened on the guide plate 2 for passing the lifting rope 3, which is used to guide the lifting rope 3 so that the lifting rope 3 can lift the aluminum wire reel into the limiting sleeve 1, and when the aluminum wire reel is lowered, it can also prevent it from shaking in the horizontal direction.

[0023] The limiting sleeve 1 includes a plurality of limiting plates that can be circumferentially arranged around the lifting rope 3, each limiting plate includes a first limiting plate unit 11, a second limiting plate unit 13 and an elastic member 12. One end of the first limiting plate unit 11 is used to be fixedly connected to the lifting arm, the other end of the first limiting plate unit 11 is fixedly connected to one end of the elastic member 12, and the other end of the elastic member 12 is fixedly connected to the second limiting plate unit 13. By arranging the elastic member 12, the limiting plate has a certain deformation amount, so as to clamp the aluminum wire reel inside the limiting sleeve 1.

[0024] The elastic member 12 is a spring.

During the movement of the crane, the wire reel is prevented from shaking back and forth. There is no need to wait for the wire reel to return to a stable state. The crane moves to the specified position and lowers the wire reel to complete the transportation of the wire reel, thereby improving the transportation efficiency.
