Description

Technical Field

[0001] This utility model relates to the field of cable winding equipment technology, specifically a cable winding device for power construction. Background Technology

[0002] In the field of power construction, efficient cable winding and proper management are crucial. With the continuous expansion of power infrastructure construction, various power projects are frequently carried out, involving a large amount of cable laying and recycling work during the construction process.

[0003] Traditional power construction cable winding equipment often struggles to effectively adjust cable tension during winding. If the cable tension is too low, the cable is prone to loose winding on the winding rollers, resulting in uneven winding, affecting subsequent use and transportation, and potentially causing the cables to squeeze each other, damaging the insulation layer and reducing cable lifespan. If the cable tension is too high, it may overstretch the internal structure of the cable, leading to conductor breakage and other problems, severely affecting the cable's electrical performance. Therefore, we propose a new type of power construction cable winding equipment. Utility Model Content

A dynamic spring is sleeved on the outer surface of each of the two connecting rods, and the two ends of the dynamic spring are respectively fixedly installed at the bottom end of the connecting plate and the upper end of the connecting block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention allows for flexible adjustment of the tension force during cable winding by changing the position of the tension rollers. Depending on the cable specifications and material, the spacing or angle of the tension rollers can be adjusted in real time to maintain a uniform and appropriate tension on the cable.

[0017] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a power construction cable winding device, including a base 1, a U-shaped bracket 2 and two vertical plates 4 fixedly connected to the upper end of the base 1, a tensioning structure 3 provided inside the U-shaped bracket 2, a winding rod 5 rotatably connected to the side end between the two vertical plates 4, one end of the winding rod 5 extending to the outer end of one of the vertical plates 4 and provided with a rotating structure, and an anti-loosening structure 6 provided at the upper end of the base 1; the tensioning structure 3 includes a threaded rod 32, which is threadedly connected to the upper end of the U-shaped bracket 2 and passes through the upper side wall of the U-shaped bracket 2, and the bottom end of the threaded rod 32 is connected to a connecting plate 31 through a bearing, a limiting rod 37 is fixedly installed at the upper end of the connecting plate 31 and passes through the upper side wall of the U-shaped bracket 2, and a tensioning roller 34 is connected to the connecting plate 31 through a dynamic adjustment structure.

[0020] In an optional embodiment: the dynamic adjustment structure includes two connecting rods 35, which are slidably connected to the upper end of the connecting plate 31. Limiting plates 36 are fixedly installed at the upper ends of the two connecting rods 35, and connecting blocks 33 are fixedly installed at the bottom ends of the two connecting rods 35. Dynamic springs 38 are sleeved on the outer surfaces of the two connecting rods 35. The two ends of the dynamic springs 38 are respectively fixedly installed at the bottom end of the connecting plate 31 and the upper end of the connecting blocks 33. The two ends of the tension roller 34 are rotatably connected to the opposite sides of the two connecting blocks 33.

[0021] It should be noted that the dynamic spring 38 adjusts the position of the tension roller 34 in real time by extending and retracting, forming a dynamic closed loop of tension change → tension roller 34 displacement → spring deformation change → elastic force adaptive adjustment → tension restoration balance. This process does not require external power or control system intervention and relies entirely on the passive elastic characteristics of the dynamic spring 38 to achieve real-time adjustment.

[0022] In an optional embodiment: the rotating structure includes a motor 8, which is fixedly installed on the side of the vertical plate 4. A sprocket 10 is fixedly installed on the output end of the motor 8 and one end of the winding rod 5. A chain 9 is connected between the two sprockets 10.

[0023] It should be noted that the chain 9 and sprocket 10 are meshing drives. The tooth ratio of the sprocket 10 at the drive wheel motor 8 end and the sprocket 10 at the driven wheel take-up rod 5 end determines a fixed transmission ratio, which ensures that the speed of the take-up roller is strictly proportional to the output speed of the motor 8. When an overload occurs during the take-up process, such as the roll jamming or a sudden increase in tension, the chain 9 and sprocket 10 may slip slightly due to insufficient friction, thus preventing the motor 8 from being damaged due to overload.

[0024] In an optional embodiment: the anti-loosening structure 6 includes two telescopic rods 62, which are fixedly installed on the upper end of the base 1. An anti-loosening stop plate 61 is fixedly installed on the upper end of the two telescopic rods 62. An anti-loosening spring 63 is sleeved on the outer surface of the two telescopic rods 62. The two ends of the anti-loosening spring 63 are respectively fixedly installed on the bottom end of the anti-loosening stop plate 61 and the upper end of the base 1.

[0025] It should be noted that, under the elastic force of the anti-loosening spring 63, the anti-loosening plate 61 continuously applies pressure perpendicular to the winding rod 5, squeezing the newly wound cable onto the previous layer surface, forcing it to adhere to the drum or the already wound layer, forming a regular spiral arrangement.

[0026] In an optional embodiment: a handle 39 is fixedly installed on the upper end of the threaded rod 32, and the outer surface of the handle 39 is provided with anti-slip texture.

[0027] It should be noted that controlling the rotation of the threaded rod 32 by turning the handle 39 is ergonomic.

[0028] In an optional embodiment: two symmetrically arranged limiting plates 7 are fixedly installed on the outer surface of the winding rod 5, and the longitudinal section of the two limiting plates 7 is circular.

[0029] It should be noted that the limiting plate 7 forms the left and right boundaries on both sides when the cable is wound up through a plane perpendicular to the axis of the winding rod 5, forcing the cable to be neatly wound along the axis of the drum, avoiding the cable edge from "running off course", stacking misalignment or even falling off due to uneven tension or equipment vibration.

[0030] In an optional embodiment: the upper longitudinal section of the anti-loosening plate 61 is arc-shaped, and the outer surface of the anti-loosening plate 61 is provided with anti-slip texture.

[0031] It should be noted that the radius of curvature of the arc-shaped cross section matches the outer diameter of the cable, so that the upper end of the anti-loosening plate 61 forms a line contact or a small area surface contact with the cable surface, rather than a rigid point contact. This avoids the cable sheath from being indented, deformed, or even damaged due to local stress concentration caused by traditional right-angle or flat plates.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] During winding, one end of the cable is wrapped around the outer surface of the winding rod 5. Then, the motor 8 is started, and the output end of the motor 8 rotates, causing the sprocket 10 fixedly installed at its output end to rotate. Under the action of the chain 9, the sprocket 10 installed at one end of the winding rod 5 will also rotate, further causing the winding rod 5 to rotate. When the winding rod 5 rotates, it can pull the cable to continuously overlap and wrap around the surface of the winding rod 5. When the cable tension needs to be adjusted according to the cable requirements, the threaded rod 32 is rotated in both directions. When the threaded rod 32 rotates, it can move up or down, thereby causing the connecting plate 31 to move up and down relative to the upper end of the U-shaped bracket 2, thereby adjusting the position of the tension roller 34, so that the cable maintains a uniform and appropriate tension, avoiding cable damage due to excessive tension or cable loosening due to insufficient tension. The static tension is set by stacking. Then, during the winding process, if the cable speed and the winding equipment speed are mismatched and suddenly accelerate or decelerate, it will cause periodic fluctuations in tension. The dynamic spring 38 adjusts the position of the tension roller 34 in real time by extending and retracting, forming a dynamic closed loop of tension change → tension roller 34 displacement → spring deformation change → elastic force adaptive adjustment → tension recovery balance. This process does not require external power or control system intervention and relies entirely on the passive elastic characteristics of the dynamic spring 38 to achieve real-time adjustment. The tension roller 34 is designed to be adjustable in vertical position and is connected by the dynamic spring 38. The two functions are complementary and irreplaceable. The anti-loosening structure 6 continuously applies pressure perpendicular to the axis of the winding rod 5, squeezing the newly wound cable onto the previous layer surface and forcing it to adhere to the drum or the already wound layer, forming a regular spiral arrangement.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
