Description

Technical Field

[0001] This application relates to the field of cable auxiliary equipment, and more specifically, to a cable take-up and delivery device. Background Technology

[0002] Currently, the cable reels used for broadcasting both domestically and internationally are all of fixed size and specifications, with their dimensions and cable capacities limited to a few standard specifications. To accommodate cables of various lengths and diameters, it is necessary to purchase or even customize cable reels of multiple sizes and specifications. Due to technological upgrades causing changes in cable models and lengths, the original fixed-specification cable reels are no longer optimally compatible. Cables exceeding the required capacity need to be replaced with new, larger-capacity reels, rendering the original smaller reels unusable. Furthermore, when cables of shorter or smaller dimensions are wound onto large reels, it wastes transportation and storage space. When preparing cable reels for cables of unknown length, the inability to predict capacity necessitates preparing multiple sizes and specifications in advance, creating pressure and difficulties for procurement and warehouse management.

[0040] This invention discloses a cable winding and unwinding device to solve the problem that when the length of an existing cable changes, the cable reel needs to be replaced, resulting in increased costs and insufficient warehouse storage space.

[0041] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0042] In related technologies, when preparing cable reels for cables of unknown length, the capacity cannot be estimated, so cable reels of various sizes and specifications must be prepared in advance, which puts pressure on procurement and warehouse management.

[0043] Please see Figure 1 , 2 and 4, Figure 1 This is a schematic diagram of the structure of a cable winding and unwinding device provided in an embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the AA-direction structure; Figure 4 for Figure 1 A schematic diagram of the rear view structure;

[0044] In one specific embodiment, the cable winding and unwinding device provided in this application includes a fixed frame 1, two roller side guards 2, and several first telescopic members 3. The fixed frame 1 can be a rectangular frame structure or a U-shaped frame structure with an open top, as long as it can fix the roller side guards 2. The specific structure is not limited and is within the protection scope of this application. The roller side guards 2 are circular plate structures, and there are two roller side guards 2. The two roller side guards 2 are preferably arranged in parallel. The roller side guards 2 are rotatably connected to the fixed frame 1 so that they can rotate around their own axis. Among them, several first telescopic members 3 are arranged between the two roller side guard plates 2. The two ends of the first telescopic members 3 can be detachably fixedly connected to the roller side guard plates 2. It can be understood that the first telescopic members 3 are arranged parallel to the axis of the roller side guard plates 2. The first telescopic members 3 extend and retract to drive the roller side guard plates 2 to move towards or away from each other, reducing or increasing the distance between them. Each first telescopic member 3 is preferably arranged at the center of the roller side guard plate 2 and symmetrically arranged along the axis of the roller side guard plate 2. Each first telescopic member 3 is preferably arranged in a circle on the roller side guard plate 2, so that each first telescopic member 3 forms a winding cylinder, and the cable is wound around each first telescopic member 3. When the first telescopic member 3 extends, the two roller side guards 2 move in opposite directions, increasing the distance between them and expanding the winding space. This allows for winding of cables of varying lengths without the need to purchase additional cable reels of the corresponding specifications. The device can accommodate cables of different lengths, reducing operating costs and improving its applicability. When the first telescopic member 3 shortens, the two roller side guards 2 move towards each other, decreasing the distance between them. This allows for storage after the winding and unwinding operations are completed, reducing the space occupied and facilitating transportation and storage while saving warehouse space.

[0045] The cable winding and unwinding device provided in this application embodiment has the following technical advantages compared to the prior art:

[0046] In this application, two roller side guards 2 are rotatably connected to the fixed frame 1. The roller side guards 2 can rotate around their own axis. The two ends of the first telescopic member 3 are respectively connected to the roller side guards 2. The roller side guards 2 move towards each other or away from each other through the first telescopic member 3 to adjust the distance between the two roller side guards 2, increase the winding space of the roller side guards 2, and enable winding of cables with varying lengths. At the same time, when it is necessary to store them in the warehouse, the first telescopic member 3 can be adjusted to make the two roller side guards 2 move towards each other, reduce the warehouse space occupied by the roller side guards 2, improve space utilization, and facilitate transportation.

[0047] As known from relevant technologies, different optical cables have different specific requirements for the minimum diameter of the cable spool when winding and storing them. Cable spools smaller than the minimum diameter requirement of the optical cable cannot be used to wind and store the optical cable. Small-diameter cable spools cannot accommodate optical cables with large-diameter winding requirements, and different diameter cable spools need to be purchased or even customized for different optical cables. In order to further enable the storage of cables of different sizes, the two ends of the first telescopic member 3 are respectively hinged to the roller side guard plate 2. Thus, when the two ends of the first telescopic member 3 have been shortened to the minimum distance, rotating the roller side guard plate 2, since the two ends of the first telescopic member 3 are respectively hinged to the roller side guard plate 2, the torque is transmitted to the hinged ends of the first telescopic member 3, and each first telescopic member 3 twists around the axis of the roller side guard plate 2. At this time, the diameter of the winding cylinder formed by the outer circumference of each first telescopic member 3 is reduced, that is, smaller than the diameter of the winding cylinder formed when the first telescopic member 3 is parallel to the axis of the roller side guard plate 2. This increases the types of cable diameters that the cable storage device can wind, enabling it to wind small-diameter cables.

[0048] like Figure 2 , 3 As shown, the two roller side guards 2 can achieve asynchronous rolling rotation within a certain angle range. When the relative rotation of the two roller side guards 2 reaches the maximum angle difference, the diameter of the cable winding shaft formed by the first telescopic member 3 is minimized, and the length of the first telescopic member 3 is also minimized. At this time, the size and diameter of the cable shaft reach the minimum limit, which can meet the winding and storage of small cables and facilitate the storage of empty cable shafts.

[0049] like Figure 7 , 8 As shown, Figure 7 A cross-sectional view of a cable retraction device in its normal operating state, as provided in an embodiment of this application; Figure 8 This is a schematic diagram of the lateral structure of a cable winding device provided in this application embodiment under normal conditions. As the relative angle difference between the two roller side guards 2 of the cable shaft gradually decreases, the winding diameter of the rollers gradually increases, which can meet the different requirements of different optical cables for winding diameter.

[0050] like Figure 5 , 6 As shown, Figure 5 A cross-sectional view of a cable retraction device in an extended state, provided in an embodiment of this application. Figure 6 This is a schematic diagram of the lateral structure of a cable winding and unwinding device in an extended state, provided in an embodiment of this application. When the relative angle difference between the two roller side guards 2 is zero, the first telescopic member 3 is parallel to the axial direction of the roller side guard 2. At this time, the diameter of the cable shaft roller reaches its maximum, and the cable shaft can meet the winding and storage needs of most cable lengths.

[0051] When the angle between the two roller side guards 2 of the cable reel roller is zero, the width of the entire cable reel can be increased by extending the length of the first telescopic member 3. By gradually increasing the distance between the two roller side guards 2 and the length of the second telescopic member 12, the cable winding and storage capacity on the roller can be infinitely varied from minimum to maximum.

[0052] In this embodiment, universal joints 4 are respectively provided at both ends of the first telescopic member 3, and a hinge seat 5 is provided on the roller side guard plate 2. The hinge seat 5 is provided with a mounting groove for mounting the universal joint 4. The specific structure of the universal joint 4 and the hinge seat 5 can be set with reference to the prior art, and will not be described in detail here. In other embodiments, other hinge structures can also be used to achieve the hinge between the first telescopic member 3 and the roller side guard plate 2, all of which are within the protection scope of this application. Among them, each first telescopic member 3 is located at the center of the roller side guard plate 2 and is symmetrically arranged with the axis of the roller side guard plate 2 as the center, so that each first telescopic member 3 surrounds to form a cylinder, which facilitates the winding of cables.

[0053] Based on the above embodiments, the first telescopic component 3 is a telescopic roller, which includes a cylinder and a slide rod. One end of the slide rod is connected to the roller side guard plate 2 through a universal joint 4, and the other end of the slide rod is fitted inside the cylinder and slides longitudinally in the cylinder. The other end of the cylinder is connected to the roller side guard plate 2 through a universal joint 4.

[0054] Based on the above embodiments, the fixed frame 1 includes two vertical support frames 11 arranged opposite each other to form a limiting cavity. The vertical support frames 11 are arranged in parallel, and the roller side guard plate 2 is located in the limiting cavity. The roller side guard plate 2 is rotatably connected to the vertical support frame 11 on the corresponding side, specifically through a bearing 6. The vertical support frame 11 includes a central mounting frame 111, a top support frame 112, and a bottom support frame 113. The central mounting frame 111 is fitted onto the shaft end on the outer side of the roller side guard plate 2, and a bearing 6 is provided between the shaft end of the roller side guard plate 2 and the central mounting frame 111. The outer side of the roller side guard plate 2 has an outwardly protruding shaft end, and a bearing 6 is fitted onto the shaft end. The inner ring of the bearing 6 is fixed to the shaft end, and the outer ring of the bearing 6 is fixed to the central mounting frame 111. The structures of the top wall support frame and the bottom support frame 113 are preferably the same, and can be set as a rectangular or triangular frame structure. The top support frame 112 and the bottom support frame 113 are respectively fixedly connected to the central mounting frame 111, and are preferably arranged centrally symmetrically. A second telescopic member 12 is provided between the top support frame 112 of the two vertical support frames 11. Two second telescopic members 12 are provided at both ends along the length direction of the top support frame 112. Similarly, two second telescopic members 12 are provided between the bottom support frame 113 of the two vertical support frames 11. The two second telescopic members 12 are located at both ends along the length direction of the bottom support frame 113.

[0055] Specifically, a roller 114 is provided at the bottom end of the bottom support frame 113. Preferably, rollers 114 are provided at both ends of the bottom support frame 113 along its length. The rollers 114 and the bottom support frame 113 are detachably fixedly connected. The rollers 114 preferably have a braking function. Their specific structure can be set according to the existing technology.

[0056] Furthermore, the top support frame 112 and the bottom support frame 113 have the same structure, including a first connecting rod 1111, a second connecting rod 1112, and a support rod 1113. The first ends of the first connecting rod 1111 and the second connecting rod 1112 are fixedly connected to the central mounting frame 111, and the second ends of the first connecting rod 1111 and the second connecting rod 1112 are respectively connected to the two ends of the support rod 1113. The support rod 1113 is arranged perpendicular to the axial direction of the roller side guard plate 2. The first connecting rod 1111, the second connecting rod 1112, and the support rod 1113 form a triangular structure to improve the stability of the device.

[0057] The width of the cable spool in the above-mentioned device can be varied to meet the storage requirements of different storage spaces; the capacity of the cable winding and storage on the cable spool can be varied and supports stepless adjustment, which can adapt to the winding and storage needs of various cables with different diameters and lengths; the winding diameter of the cable in the cable spool can be varied to adapt to the different winding diameter requirements of different optical cables.
