Description

Technical Field

[0001] This utility model relates to the field of electric hoist technology, specifically to an electric hoist wire rope winding device. Background Technology

[0002] An electric hoist is a lifting device installed on overhead cranes and gantry cranes. Electric hoists are characterized by their small size, light weight, simple operation, and ease of use. They are used in industrial and mining enterprises, warehouses, docks, and other places. Electric hoists are divided into two types: wire rope electric hoists and chain electric hoists. Chain electric hoists are further divided into imported and domestic models. Wire rope electric hoists are available in single-speed and dual-speed lifting models. Mini electric hoists, winches, and multi-functional hoists feature a dual-control hydraulic system. Overflow regulating valves and magnetic contact pressure gauges allow for precise pressure control. The electrical control system employs low-voltage control, increasing the safety of the control system.

[0003] As modern industry demands ever higher lifting height, operational efficiency, and safety lifespan, traditional electric hoist wire rope winding devices have been found to suffer from problems during winding. These problems include wire rope misalignment and interlocking of strands, which can lead to instantaneous breakage under gravity, thus reducing the device's effectiveness. Therefore, we provide an electric hoist wire rope winding device to solve these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an electric hoist wire rope winding device to solve the problems mentioned in the background art and overcome its technical defects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an electric hoist wire rope winding device, including a guide frame, with mounting plates fixedly connected to both the front and back of the guide frame, a positioning frame inside the guide frame, and rollers fixedly installed on the outer surface of the positioning frame, the rollers being adapted to the guide frame, two limiting discs below the guide frame, a connecting cover fixedly connected to the side of the two limiting discs that are close to each other, a connecting block fixedly connected to the upper surface of the connecting cover, the bottom end of the positioning frame fixedly connected to the upper surface of the connecting block, bearings fixedly embedded on the side of the two limiting discs that are close to each other, a rotating rod rotatably connected to the inner rings of the two bearings, a drive motor fixedly installed on the left side of one of the limiting discs, the left end of the rotating rod fixedly connected to the output end of the drive motor, and wire rope wound on the outer surface of the rotating rod.

[0006] Preferably, each of the mounting plates has three mounting holes on its upper surface, and each mounting hole has a threaded inner ring.

[0007] Preferably, two stabilizing plates are fixedly connected to both the front and back of the guide frame, and the top of each stabilizing plate is fixedly connected to the bottom surface of the mounting plate.

[0008] Preferably, a reinforcing ring is fixedly connected to the upper surface of the connecting block, and the inner ring of the reinforcing ring is fixedly connected to the outer surface of the positioning frame.

[0009] Preferably, each of the two limiting discs has an arc-shaped groove on one side that is close to each other, and a sliding block is slidably connected inside each arc-shaped groove.

[0010] Preferably, a guide block is provided between the two limiting discs, and two sliding holes are provided on the right side of the guide block. A guide hole is provided on the upper surface of the guide block, and the guide hole is adapted to the wire rope.

[0011] Preferably, each of the sliding holes is slidably connected to a sliding rod, and the left and right ends of the sliding rod are respectively fixedly connected to the side of the sliding block that is close to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model include:

[0013] The drive motor rotates the rotating rod, which rotates smoothly within the limit plate using bearings, while the guide block slides within the arc-shaped groove. This ensures that the wire rope is always in the correct position, preventing deviation and effectively avoiding misalignment and strand interlocking during wire rope winding. The rollers on the positioning frame roll within the guide frame, working in conjunction with the connecting block and reinforcing ring to enhance the stability of the device. This effectively solves the problems of wire rope misalignment and strand interlocking during winding, and the wire rope's tendency to break instantly under gravity. Attached Figure Description

[0020] 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.

[0021] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0022] An electric hoist wire rope winding device includes a guide frame 1. Mounting plates 2 are fixedly connected to both the front and back of the guide frame 1. A positioning frame 5 is provided inside the guide frame 1. Rollers 6 are fixedly mounted on the outer surface of the positioning frame 5 and are adapted to the guide frame 1. Two limiting discs 7 are provided below the guide frame 1. Connecting covers 8 are fixedly connected to the sides of the two limiting discs 7 that are close to each other. Connecting blocks 9 are fixedly connected to the upper surface of the connecting covers 8. The bottom end of the positioning frame 5 is fixedly connected to the upper surface of the connecting blocks 9. Bearings 13 are fixedly embedded on the sides of the two limiting discs 7 that are close to each other. A rotating rod 12 is rotatably connected to the inner rings of the two bearings 13. A drive motor 19 is fixedly mounted on the left side of one of the limiting discs 7. The left end of the rotating rod 12 is fixedly connected to the output end of the drive motor 19. Wire rope 18 is wound around the outer surface of the rotating rod 12.

[0023] In this embodiment, each mounting plate 2 has three mounting holes 3 on its upper surface, and each mounting hole 3 has a threaded inner ring. Two stabilizing plates 4 are fixedly connected to the front and back of the guide frame 1. The top of each stabilizing plate 4 is fixedly connected to the bottom surface of the mounting plate 2. The device can be installed through the mounting holes 3, which also increases the stability of the mounting plate 2 and the guide frame 1. A reinforcing ring 10 is fixedly connected to the upper surface of the connecting block 9. The inner ring of the reinforcing ring 10 is fixedly connected to the outer surface of the positioning frame 5. The reinforcing ring 10 ensures the stability of the connecting block 9 and the positioning frame 5.

[0024] In this embodiment, each of the two limiting discs 7 has an arc-shaped groove 14 on one side that is close to each other. A sliding block 15 is slidably connected inside each arc-shaped groove 14. A guide block 17 is provided between the two limiting discs 7. Two sliding holes 11 are provided on the right side of the guide block 17. A guide hole 20 is provided on the upper surface of the guide block 17, and the guide hole 20 is adapted to the wire rope 18. A sliding rod 16 is slidably connected inside each sliding hole 11. The left and right ends of the sliding rod 16 are fixedly connected to the side of the sliding block 15 that is close to each other. The rotating rod 12 is driven to rotate by the drive motor 19, and rotates smoothly in the limiting disc 7 using the bearing 13. The guide block 17 slides in the arc-shaped groove 14 to ensure that the wire rope 18 is always in the correct position, preventing the wire rope 18 from deviating. This effectively avoids the problem of the wire rope 18 being confused and the strands interlocking when it is wound up.

[0025] Working principle: In use, first connect the drive motor 19 to the power supply and control it through the control switch. After the drive motor 19 starts, its output end drives the rotating rod 12 to rotate. The rotating rod 12 rotates between the two limit plates 7 through the bearing 13, thereby realizing the winding action of the wire rope 18. The wire rope 18 passes through the guide hole 20 on the guide block 17. The guide block 17 slides in the arc-shaped groove 14 through the sliding rod 16 and the sliding block 15, thereby ensuring that the wire rope 18 always stays in the correct position during the winding process. The left and right ends of the sliding rod 16 are fixedly connected to the side of the sliding block 15 that is close to each other. The sliding block 15 slides in the arc-shaped groove 14, thereby realizing the movement of the guide block 17.

[0026] The rollers 6 on the positioning frame 5 roll within the guide frame 1, ensuring that the positioning frame 5 moves smoothly during the winding process. The stability of the device is further enhanced by the cooperation of the connecting block 9 and the reinforcing ring 10, ensuring that the wire rope 18 will not deviate or become disordered during the winding process. Through the synergistic effect of the above structures, problems such as disorder and interlocking of strands in the wire rope 18 during winding are effectively avoided, significantly improving the performance of the device.

[0027] 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.
