Description
Technical Field
[0001] This utility model relates to the technical field of drum equipment, and in particular to a rope guide for double-layer winding of steel wire rope on a drum. Background Technology
[0002] In lifting and traction equipment, drums achieve lifting or traction of heavy objects by winding steel wire ropes. To increase the steel wire rope storage capacity of the drum, double winding has become a common method. However, existing drums lack dedicated rope guides or have significant defects when double-winding steel wire ropes, affecting work efficiency and safety: poor adaptability, unable to accommodate different sizes of steel wire ropes; the core components of existing rope guides form a fixed guiding space for the steel wire rope, making it impossible to flexibly adjust according to different diameter steel wire ropes. When changing to different specifications of steel wire rope, workers need to purchase the corresponding size rope guide body, which not only increases equipment purchase costs but also requires frequent rope guide replacements, reducing work efficiency. Lack of buffer protection, severe wear between the steel wire rope and the rope guide; during high-speed winding, the steel wire rope will experience severe friction with the inner wall of the guide. Existing rope guides are mostly made of hard metal structures without buffer protection design. With prolonged use, not only are scratches and broken wires easily appearing on the surface of the wire rope, but the inner wall of the rope guide also suffers wear, leading to a decrease in guiding accuracy, shortening the service life of both and increasing equipment maintenance costs. Installation and adjustment are inconvenient, and adapting to different drums is difficult. Traditional rope guides mostly use a fixed installation structure, requiring precise alignment with the drum during installation, and cannot be fine-tuned according to parameters such as the drum's diameter and length. When changing to different drum specifications, the rope guide needs to be disassembled, drilled, and reinstalled, making the operation cumbersome, with poor adaptability, and unable to meet the diverse double-layer winding requirements of drums.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: because the space enclosed by the traditional semi-circular plate, long frame and short frame is fixed in size, it cannot be adapted and adjusted according to the different sizes of steel wire ropes. As a result, workers need to purchase the corresponding rope guide body for steel wire ropes of different specifications, which significantly increases the purchase cost of the rope guide body. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the space enclosed by the traditional semi-circular plate, long frame and short frame is fixed and cannot be adapted and adjusted according to the different sizes of the wire rope. To this end, we propose a rope guide for double-layer winding of wire rope on a drum.
[0005] To achieve the above objectives, this application adopts the following technical solution: a rope guide for double-layer winding of steel wire rope on a drum, comprising a rope guide body, a semi-arc plate slidably connected to the arc surface of the rope guide body, a telescopic plate fixedly connected to one end of the semi-arc plate, a sliding plate fixedly connected to one end of the semi-arc plate, a long frame slidably connected to the surface of the telescopic plate, a short frame slidably connected to the surface of the sliding plate, three screw holes opened on the arc surface of the long frame, a screw threaded into the inner wall of the screw holes of the long frame, and a limit hole opened on the arc surface of the short frame. The inner wall of the guide is threaded with a limiting rod. The arc surface of the guide body has several fixing grooves. The screw is threaded to the inner wall of the fixing groove of the guide body. The limiting rod is threaded to the inner wall of the fixing groove of the guide body. The arc surfaces of the long frame and the short frame are fixedly connected with square plates. The arc surface of the semi-arc plate is fixedly connected with two L-shaped plates.

[0007] Preferably, the arc surface of the semi-arc plate is fixedly connected to two fixing plates, and a round rod is fixedly connected to one side of the two fixing plates that are close to each other.
[0008] Preferably, one end of the threaded rod is fixedly connected to a rotating plate, and the size of the telescopic plate is adapted to the size of the inner surface of the long frame.

Detailed Implementation
[0014] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0015] Reference Figure 1-7As shown, this utility model provides a technical solution: a rope guide for double-layer winding of steel wire rope on a drum, comprising a rope guide body 1, a semi-arc plate 2 slidably connected to the arc surface of the rope guide body 1, a telescopic plate 3 fixedly connected to one end of the semi-arc plate 2, a sliding plate 4 fixedly connected to one end of the semi-arc plate 2, a long frame 5 slidably connected to the surface of the telescopic plate 3, and a short frame 6 slidably connected to the surface of the sliding plate 4. The arc surface of the long frame 5 has three screw holes, and a screw 7 is threadedly connected to the inner wall of the screw holes of the long frame 5. The arc surface of the short frame 6 has a limiting hole, and a limiting rod 20 is threadedly connected to the inner wall of the limiting hole of the short frame 6. The arc surface of the rope guide body 1 has several fixing grooves, and the screw 7 is threadedly connected to the inner wall of the fixing groove of the rope guide body 1. The limiting rod 20 is threadedly connected to the inner wall of the fixing groove of the rope guide body 1. The inner wall of the fixing groove of body 1 is threaded. Square plates 8 are fixedly connected to the arc surfaces of both the long frame 5 and the short frame 6. Two L-shaped plates 9 are fixedly connected to the arc surface of the semi-arc plate 2. Each L-shaped plate 9 has four threaded grooves on its surface. A connecting plate 10 is fixedly connected to one side of the square plate 8. A threaded rod 11 is threaded into the inner thread of the connecting plate 10. The threaded rod 11 is threaded to the inner wall of the threaded groove of the connecting plate 10. This achieves the effect of adjusting the space enclosed by the semi-arc plate 2, the long frame 5, and the short frame 6. This avoids the problem that the space enclosed by the traditional semi-arc plate 2, the long frame 5, and the short frame 6 is fixed and cannot be adapted to different sizes of wire ropes, thus requiring workers to purchase separate rope guide bodies 1 for different specifications of wire ropes. This increases the purchase cost of the rope guide body 1. A first spring 12 is fixedly connected to the inner surface of the long frame 5, and the other end of the first spring 12 is fixedly connected to the telescopic plate 3. A second spring 13 is fixedly connected to the inner surface of the short frame 6, and the other end of the second spring 13 is fixedly connected to the sliding plate 4. The spring has an initial elastic force. When the limit on the semi-arc plate 2 is released, the spring in the stretched state will quickly release the elastic force, driving the semi-arc plate 2 to quickly return to the initial position, providing convenience for subsequent operation by the staff. Two fixed plates 14 are fixedly connected to the arc surface of the semi-arc plate 2. A round rod 15 is fixedly connected to the side of the two fixed plates 14 that are close to each other. The fixed plates 14 and the round rod 15 cooperate with each other to provide a stable force when the staff drives the semi-arc plate 2 to move. A pivot point is established, and a rotating plate 16 is fixedly connected to one end of the threaded rod 11. The dimensions of the telescopic plate 3 are adapted to the dimensions of the inner surface of the long frame 5. The purpose of installing the rotating plate 16 is to allow the operator to quickly drive the threaded rod 11 forward or backward without relying on additional tools. Friction pads 17 are fixedly connected to the arc surfaces of the round rod 15 and the rotating plate 16. The dimensions of the threaded rod 11 are adapted to the dimensions of the threaded groove of the L-shaped plate 9. The friction pads 17 are elastic and soft, which can increase the friction between the operator's hand and the round rod 15 and the rotating plate 16 to prevent slippage during operation, and also buffer the direct contact between the hand and the round rod 15 and the rotating plate 16, providing the operator with a more comfortable grip and force application experience. A triangular plate 18 is fixedly connected to one side of the square plate 8.Two guide plates 19 are fixedly connected to one side of the square plate 8. The triangular plate 18 and the guide plates 19 can effectively guide the workers clearly in the direction of movement of the semi-circular plate 2.
[0016] Working principle: When workers need to deliver steel wire ropes of different sizes, they first pass the steel wire rope through the gap between the long frame 5 and the short frame 6, allowing it to enter the space enclosed by the semi-arc plate 2, the long frame 5, and the short frame 6, thus compressing the semi-arc plate 2. Then, the workers push the friction pad 17 on the arc surface of the round rod 15 upwards. The friction pad 17 drives the round rod 15 to move, which in turn drives the fixed plate 14 upwards. The fixed plate 14 then drives the compressed semi-arc plate 2 upwards. During this upward movement, the semi-arc plate 2 simultaneously drives the telescopic plate 3 and the sliding plate 4 upwards, stretching the first spring 12 and the second spring 13. During this process, the L-shaped plate 9 moves synchronously with the semi-arc plate 2 until the space enclosed by the semi-arc plate 2, the long frame 5, and the short frame 6 is adapted to the current size of the steel wire rope. Finally, simply rotate the friction pad 17 on the arc surface of the rotating plate 16. The friction pad 17 drives the rotating plate 16 to rotate, and the rotating plate 16 further drives the threaded rod 11 forward until the threaded rod 11 enters the threaded groove of the L-shaped plate 9, completing the limiting of the semi-arc plate 2. At this time, the space enclosed by the semi-arc plate 2, the long frame 5, and the short frame 6 is exactly matched with the size of the steel wire rope being exported. This achieves the effect of adjusting the size of the space enclosed by the semi-arc plate 2, the long frame 5, and the short frame 6. This avoids the problem that the space enclosed by the traditional semi-arc plate 2, the long frame 5, and the short frame 6 is fixed and cannot be adapted to different sizes of steel wire ropes. As a result, workers need to purchase the corresponding rope guide body 1 for different specifications of steel wire ropes, which significantly increases the purchase cost of the rope guide body 1.
[0017] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
