Description

Technical Field

[0001] This utility model relates to the field of electric hoist technology, and specifically to an anti-slip mechanism for the wire rope of an electric hoist. Background Technology

[0002] Electric hoists are widely used for lifting heavy objects. They use wire rope wound on a drum, and the rotation of the drum enables the wire rope to be wound up and down, thereby lifting the heavy object. Some electric hoists fix one end of the wire rope to improve efficiency, and the hook slides on the wire rope to achieve the lifting effect by winding up and down the wire rope. In the existing technology, the fixed end of the wire rope of the electric hoist is fixed by the gap between the wedge block and the outer clamp. However, this method can cause the wire rope and the wedge block to move upward when the wire rope is not tensioned. When the force is applied downward again, the wire rope can easily get stuck between the side of the wedge block and the inner wall of the clamp, causing damage to the wire rope and posing a danger to the lifting process. Therefore, this technical solution is proposed to improve the method. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology in which the fixed end of the wire rope of the electric hoist is prone to upward movement and noise damage, and to provide an anti-spinning mechanism for the wire rope of the electric hoist.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an anti-slip mechanism for wire rope of an electric hoist, comprising an electric hoist body, a drum cover provided on the outside of the electric hoist body, a retainer provided on the side wall of the drum cover, a wedge-shaped block for winding the wire rope provided inside the retainer, a stop block provided above the retainer, and the distance between the stop block and the retainer is adjustable.

[0005] Furthermore, an opening for the movement of the wire rope is provided on the other side of the drum cover, and a connecting frame is provided on the upper part of the drum cover.

[0006] Furthermore, the stop block includes a connecting block connected to the roll cover, the connecting block having an oblong hole, the lower part of the connecting block having a right-angle plate, and the tail of the right-angle plate covering the upper part of the sleeve.

[0007] Furthermore, the aperture of the card sleeve is larger at the top and smaller at the bottom.

[0008] Furthermore, the wedge block is a raindrop shape with a larger top and a smaller bottom, the span of the wedge block is greater than the width of the sleeve, the side of the wedge block is provided with a groove for accommodating the wire rope, and the bottom of the wedge block is provided with a clip for clamping the wire rope.

[0009] The beneficial effects of this utility model embodiment are as follows: A retaining sleeve is fixedly installed on the side wall of the drum cover. The inside of the retaining sleeve is used to place and fix the wedge-shaped block wound with the wire rope. The retaining sleeve is designed with a structure where the diameter is larger at the top and smaller at the bottom, which helps the wire rope to be more tightly fixed in the retaining sleeve under the action of the wedge-shaped block. This makes the pulley hook below have a blocking effect when descending, preventing it from falling off. A stop block is set above the retaining sleeve. The design of the stop block utilizes the structural characteristics of the drum cover. It is connected to the drum cover through a connecting block. The connecting block is provided with a waist-shaped hole, which allows the stop block to be flexibly adjusted in the tangential direction of the drum cover, thereby adapting to wire ropes of different diameters and tensions. At the same time, the connecting block can also be disassembled, which is convenient for replacing the wire rope installation frame. A right-angle plate is set at the lower part of the connecting block. The tail of the right-angle plate just covers the upper part of the retaining sleeve, forming an effective physical barrier to prevent the wire rope from moving upward after it is not tensioned or unloaded, reducing the probability of jamming between the wedge-shaped block and the retaining sleeve, and improving the safety of use.

[0017] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] See Figures 1 to 6This utility model discloses an anti-slip mechanism for the wire rope of an electric hoist, mainly composed of an electric hoist body, a drum cover 1, a clamping sleeve 2, a wedge block 303, and a stop block 3. The electric hoist body serves as the supporting foundation of the entire mechanism. The drum cover 1 is provided on its exterior to protect the drum and the internal wire rope. A connecting frame is provided on the upper part of the drum cover 1 to provide the necessary installation space for the electric hoist body. A clamping sleeve 2 is fixedly installed on the side wall of the drum cover 1. The wedge block 303, which is wound around the wire rope, is placed and fixed inside the clamping sleeve 2. The clamping sleeve 2 is designed with a structure where the diameter is larger at the top and smaller at the bottom, which helps the wire rope to be more tightly fixed in the clamping sleeve 2 under the action of the wedge block 303. This makes the pulley hook below have a blocking effect when descending, preventing it from falling off and reducing the possibility of slippage.

[0019] As the core component for fixing the wire rope, the wedge block 303 is designed in a raindrop shape, wider at the top and narrower at the bottom, with a span slightly larger than the width of the clamp 2. This ensures that the wire rope can fit tightly against the inner wall of the clamp 2 when tensioned, forming a reliable fixation. The side of the wedge block 303 is provided with a groove for accommodating the wire rope. The shape and size of the groove match the wire rope to ensure that the wire rope can be stably placed inside the wedge block 303. In addition, a clip 4 for clamping the wire rope is provided below the wedge block 303, further enhancing the fixing effect of the wire rope. After a period of use, it is convenient to replace or maintain the wire rope, improving the performance.

[0020] To prevent the wire rope from moving upwards when it is not tensioned, a stop block 3 is installed above the ferrule 2. The design of the stop block 3 utilizes the structural features of the drum cover 1 and is connected to the drum cover 1 via a connecting block 301. The connecting block 301 has a waist-shaped hole, which allows the stop block 3 to be flexibly adjusted in the tangential direction of the drum cover 1 to accommodate wire ropes of different diameters and tensions. At the same time, the connecting block 301 can also be disassembled for easy replacement of the wire rope installation frame. A right-angle plate 302 is installed at the lower part of the connecting block 301. The tail of the right-angle plate 302 covers the upper part of the ferrule 2, forming an effective physical barrier to prevent the wire rope from moving upwards when it is not tensioned or unloaded, reducing the probability of jamming between the wedge block 303 and the ferrule 2 and improving safety in use.

[0021] On the other side of the drum cover 1, an opening is provided for the movement of the wire rope so that the wire rope can smoothly enter and exit the drum cover 1 to realize the hoisting operation. A movable frame 101 that moves with the wire rope is provided at the opening. The movable frame 101 is slidably set at the opening to assist the wire rope and prevent the wire rope from getting tangled during the rising or falling process, thereby improving the use effect. A limiter is provided on the upper part of the pulley hook to ensure safe use.

[0022] In practical applications, when the wire rope is wound around the wedge block 303 and tensioned, the wedge block 303 fits tightly against the clamp 2 under the tension of the wire rope, forming a reliable fixation. Simultaneously, the presence of the stop block 3 effectively prevents the wire rope from moving upwards in an untensioned state, avoiding the risk of the wire rope getting stuck between the side of the wedge block 303 and the inner wall of the clamping platform. When it is necessary to adjust the tension of the wire rope or replace it, simply adjusting the position of the stop block 3 or loosening the clamp 4 easily loosens or disassembles the wire rope, solving the problems of easy movement and damage of the wire rope in existing technologies, and improving the safety and stability of hoisting operations.
