Description

Technical Field

[0001] This utility model relates to the field of cable laying, specifically to a cable laying winding device. Background Technology

[0002] In the process of cable transportation, storage, laying and recycling, winding devices are essential equipment. They can neatly wind long-distance cables into coils, reduce space occupation, facilitate handling and on-site transfer, and allow for smooth release of cables during construction. Therefore, a cable laying winding device is needed.

[0003] Existing cable laying winding devices are prone to causing the drum to reverse due to the cable's own weight during operation, resulting in the cable becoming loose. Cables have a fixed minimum bending radius, and excessive bending can lead to problems such as insulation layer cracking, internal conductor breakage, or armor layer deformation. Therefore, there is an urgent need for a cable laying winding device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a cable laying winding device to solve the problems that existing cable laying winding devices are prone to the drum reversing due to the cable's own weight during use, causing the cable to loosen. The cable has a fixed minimum bending radius, and excessive bending can lead to insulation layer cracking, internal conductor breakage, or armor layer deformation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable laying winding device, comprising a mounting frame, with abutment frames installed on both sides of the mounting frame, an adjusting rod welded to the inner wall of the abutment frame, an adjusting sleeve installed on the outer wall of the adjusting rod, a first spring abutting the outer wall of the adjusting sleeve, a rotating toothed rod installed on the adjusting sleeve, a rotating shaft abutting one end of the abutment frame, rotating beads fitting against the inner wall of the mounting frame, and a cable body installed on the outer wall of the rotating shaft.

[0006] The inner wall of each mounting bracket is equipped with a support frame, one end of which abuts against a second spring, and one end of the second spring abuts against a tensioning frame. The outer wall of each tensioning frame is equipped with a rotating cylinder.

[0007] Preferably, the mounting bracket is movably connected to the abutment bracket, and the abutment bracket is symmetrically arranged about the central axis of the mounting bracket.

[0008] Preferably, the adjusting rod is threadedly connected to the adjusting sleeve, and the outer wall of the adjusting rod is threaded.

[0009] Preferably, the rotating gear is movably connected to the contact frame, and the rotating gear is engaged with the adjusting sleeve.

[0010] Preferably, the rotating shaft is formed into a rotating structure with the mounting frame via rotating beads, and the rotating beads are arranged in a ring array on the outer wall of the rotating shaft.

[0011] Preferably, the support frame is engaged with the mounting frame, and the support frame is symmetrically arranged about the central axis of the mounting frame.

[0012] Preferably, the rotating drums are arranged at equal intervals on the outer wall of the tensioning frame, and the tensioning frame is arranged parallel to the second spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model features a manually rotating gear. Because the gear and adjusting sleeve are meshed, the rotation of the gear is converted into the axial lifting motion of the adjusting sleeve. When the gear is rotated clockwise, the adjusting sleeve moves downwards along the teeth, compressing the first spring below. When rotated counterclockwise, the adjusting sleeve moves upwards, releasing the compression of the first spring and reducing its elasticity. Through this meshing transmission, the compression of the first spring can be precisely adjusted, thereby changing the magnitude of its output elasticity, which is crucial for subsequent engagement. The first spring's elastic force is transmitted to the contact frame through the adjusting sleeve, pushing the contact end of the contact frame closer to the rotating shaft and tightly fitting it. A stable contact pressure is formed between the contact frame and the rotating shaft. The contact locking effect generated by this pressure will form a one-way locking effect on the rotating shaft. During the laying of the cable body, its own weight will exert a downward pulling force on the rotating shaft, attempting to drive the rotating shaft to reverse. The contact locking force of the contact frame on the rotating shaft just cancels out this reverse pulling force, preventing the rotating shaft from undergoing any reverse displacement. 2. This utility model uses an installation frame to lock and fix the support frame. The inclined design of the tightening frame dynamically fits the rotating drum, and the inclination angle matches the cable body's outgoing trajectory, avoiding sharp-angle bends in the cable body and keeping the bending angle within a safe range. The rolling contact of the rotating drum replaces sliding friction, reducing wear on the cable body surface and dispersing local stress through flexible support. This effectively reduces stress accumulation inside the cable body during the laying process. In long-term laying operations, excessive stress accumulation can easily lead to damage to the internal structure of the cable. This design avoids this problem from the source and extends the cable's service life. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The embodiments of this utility model will be described below based on its overall structure.

[0018] Please see Figure 1-6A cable laying winding device includes a mounting frame 1, with contact frames 2 mounted on both sides of the mounting frame 1. The mounting frame 1 and the contact frames 2 are movably connected, and the contact frames 2 are symmetrically arranged about the central axis of the mounting frame 1. An adjusting rod 3 is welded to the inner wall of the contact frame 2, and an adjusting sleeve 4 is mounted on the outer wall of the adjusting rod 3. The adjusting rod 3 and the adjusting sleeve 4 are threaded together, and the outer wall of the adjusting rod 3 is threaded. A first spring 5 abuts against the outer wall of the adjusting sleeve 4, and a rotating toothed rod 6 is mounted on the adjusting sleeve 4. The rotating gear 6 is movably connected to the contact frame 2, and the rotating gear 6 is meshed with the adjusting sleeve 4. One end of the contact frame 2 abuts against the rotating shaft 7. The inner wall of the mounting frame 1 is fitted with rotating balls 8. The rotating shaft 7 and the mounting frame 1 form a rotating structure through the rotating balls 8. The rotating balls 8 are arranged in a ring array on the outer wall of the rotating shaft 7. The cable body 9 is installed on the outer wall of the rotating shaft 7. By manually rotating the rotating gear 6, since the rotating gear 6 and the adjusting sleeve 4 are in a toothed meshing fit, the rotational movement of the rotating gear 6 will rotate the rotating shaft 7. The axial lifting and lowering motion of the adjusting sleeve 4 is transformed into the downward movement of the toothed rod 6 when the adjusting sleeve 4 moves downward along the toothed groove, generating a compressive force on the first spring 5 below. When rotating counterclockwise, the adjusting sleeve 4 moves upward, releasing the compressive force of the first spring 5 and reducing the elastic force. Through this meshing transmission, the compression of the first spring 5 can be precisely adjusted, thereby changing the magnitude of its output elastic force and providing suitable pressure for subsequent locking. The elastic force of the first spring 5 is transmitted to the contact frame 2 through the adjusting sleeve 4, pushing the contact end of the contact frame 2 closer to the rotating shaft 7 and tightly fitting it. A stable contact pressure is formed between the contact frame 2 and the rotating shaft 7. The contact locking effect generated by this pressure will form a one-way locking effect on the rotating shaft 7. When the cable body 9 is laid, its own weight will generate a downward pulling force on the rotating shaft 7, attempting to drive the rotating shaft 7 to reverse. However, the locking force of the contact frame 2 on the rotating shaft 7 precisely cancels out this reverse pulling force, preventing the rotating shaft 7 from any reverse displacement.

[0019] Please see Figure 1-6A cable laying winding device includes a mounting frame 1 with support frames 10 installed on the inner wall of the mounting frame 1. The support frames 10 are engaged with the mounting frame 1 and are symmetrically arranged about the central axis of the mounting frame 1. One end of each support frame 10 abuts against a second spring 11, and one end of each second spring 11 abuts against a tightening frame 12. Rotary drums 13 are installed on the outer wall of each tightening frame 12 at equal intervals. The tightening frame 12 is parallel to the second spring 11. The mounting frame 1 secures and locks the support frames 10 in place. The inclined design of the tightening frame 12 and the dynamic fit of the rotating drum 13 match the cable body 9's exit trajectory, preventing the cable body 9 from making sharp-angle bends and keeping the bending angle within a safe range. The rolling contact of the rotating drum 13 replaces sliding friction, which reduces wear on the surface of the cable body 9 and disperses local stress through flexible support, effectively reducing stress accumulation inside the cable body 9 during the cable laying process. In long-term cable laying operations, excessive stress accumulation can easily lead to damage to the internal structure of the cable, while this design avoids this problem from the source and extends the cable's service life.

[0020] Working principle: When in use, take out the mounting bracket 1 and place it in the designated position. Then, use the support bracket 10 to lock and fix the mounting bracket 1. Next, use the contact bracket 2 to rotate and adjust the rotating gear 6. Adjust the rotating gear 6 to the adjusting sleeve 4 to the designated height. Press the first spring 5 to remove the cable body 9. Finally, pull and lay the cable body 9. This completes the use of the device.
