[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiment is only one embodiment of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0026] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] In the following description, references to "one embodiment", "an embodiment", "an example", "an example", etc. indicate that the embodiment or example described in this way may include specific features, structures, characteristics, properties, elements or limitations, but not every embodiment or example necessarily includes the specific features, structures, characteristics, properties, elements or limitations. In addition, repeated use of the phrase "according to one embodiment of the present application" may refer to the same embodiment, but does not necessarily refer to the same embodiment.

[0028] like Figure 1-4 As shown, the present invention discloses a laying device and a laying method for communication cables, which include a support member 1 and a separator 2. The number of the support members 1 is multiple, and the multiple support members 1 are connected end to end. The support member 1 includes a bracket 11 and a rotating shaft 12. The two adjacent brackets 11 are detachably connected. The two ends of the rotating shaft 12 are rotatably connected and detachably connected to the two sides of the bracket 11, respectively. The rotating shaft 12 is used to install the cable reel 3. The separator 2 includes a mounting frame 21 and a plurality of rollers 22. The mounting frame 21 is detachably connected to the bracket 11 at the most front end or the most rear end. The plurality of rollers 22 are distributed at intervals in the longitudinal direction and are rotatably connected and detachably connected to the mounting frame 21, respectively. In this embodiment, three support members 1 are arranged from left to right, and the three support members 1 are connected end to end. The separator 2 is installed on the bracket 11 at the leftmost end, that is, the mounting frame 21 is adapted to the left end of the bracket 11 and is detachably connected. The two ends of the roller 22 are respectively connected with the limiting sleeve by snapping or threading, so that the roller 22 can be removed from the installation frame 21, and the spacing between the rollers 22 can be adjusted according to actual conditions, so as to facilitate better laying of communication cables.

[0029] In actual use, the base can be buried underground, that is, according to the design requirements, a hole of appropriate size is dug at the designated location to ensure that the shape, size and depth of the hole meet the requirements for the burial of the base. At the same time, the sundries and gravel in the hole are cleaned to ensure that the base can be placed stably, and the base is placed in the hole. This can prevent the device from shaking or tilting due to vibration or external force during use.

[0030] When in use, remove the three rotating shafts 12, pass through the inner rings of the three cable drums 3 respectively, and then install the rotating shafts 12 together with the cable drums 3 on the bracket 11. The three cables are placed on the three rollers 22 respectively, and then the three cables are installed on the external wire-laying trolley 6 in turn for use. The wire-laying trolley 6 is equipped with a driving system, such as a motor 43 or a hydraulic motor, which is used to drive the rotating shaft 12 to rotate, thereby realizing the automatic laying of the cables. The wire-laying trolley 6 is a prior art and will not be described in detail here. If the working conditions of the wire-laying trolley 6 are not met, a manual wire-laying trolley 6 can be used to manually lay the wires. In addition, a wire-laying sleeve can be used to fix the head ends of the three cables at the starting point of cable laying, and then the device can be placed on a flatbed trailer for mobile wire-laying and laying.

[0031] A plurality of support members 1 are connected end to end to form a support frame with adjustable length. This design allows the length of the device to be flexibly adjusted according to the specific needs of the laying site. Both ends of the rotating shaft 12 are rotatably connected to the bracket 11 and are detachable, which is convenient for installing and replacing the cable drum 3. During the cable laying process, the rotating shaft 12 can rotate smoothly, thereby driving the cable drum 3 to rotate and realize continuous output of the cable. At the same time, the spaced distribution of the rollers 22 helps to keep the cables neatly arranged and prevent entanglement and knotting.

[0032] The present invention provides a modular design and detachable connection of a separator 2 and a plurality of support members 1, so that the device can be quickly assembled and disassembled, thereby improving the efficiency and flexibility of laying communication cables. The design of the roller 22 reduces the friction between the cable and the device, thereby speeding up the laying speed. At the same time, multiple communication cables can be laid simultaneously according to the actual situation on site, thereby greatly shortening the laying time and improving the work efficiency.

[0033] In one embodiment, two adjacent brackets 11 are bolted together, and the mounting frame 21 is bolted to the bracket 11. That is, the two adjacent brackets 11 and the mounting frame 21 are both connected by high-strength bolts.

[0034] In one embodiment, both sides of the bracket 11 are provided with mounting openings 15 that are open upwards, and the two ends of the rotating shaft 12 are respectively arranged in the two mounting openings 15. The support member 1 also includes a plurality of rollers 13, which are symmetrically arranged on both sides of the bottom of the rotating shaft 12 and are rotatably connected to the bracket 11, and the plurality of rollers 13 are respectively rotatably connected to the rotating shaft 12. In this embodiment, four rollers 13 are provided, corresponding to the two ends of the rotating shaft 12 and the two sides of the bracket 11, and the four rollers 13 are all installed on the inner side of the bracket 11. When installing the rotating shaft 12, it is only necessary to put the rotating shaft 12 into the mounting opening 15 so that the two ends of the rotating shaft 12 are respectively placed on the rollers 13 on both sides of the bracket 11.

[0035] The rollers 13 can support the weight of the rotating shaft 12 and the cable drum 3, reducing the burden on the bracket 11. At the same time, since the rollers 13 are symmetrically arranged, they can also help maintain the balance of the rotating shaft 12 and the cable drum 3 during the rotation process. At the same time, the rolling contact between the rollers 13 and the bracket 11 and the rotating shaft 12 has less friction resistance than the sliding contact, which makes the rotating shaft 12 rotate more smoothly and reduces energy loss and wear.

[0036] In one embodiment, the support member 1 also includes two limit covers 14, which are respectively mounted on both ends of the rotating shaft 12 and are respectively rotatably connected to the rotating shaft 12. The two limit covers 14 are respectively bolted to the bracket 11, that is, both ends of the limit covers 14 are connected to the bracket 11 through high-strength bolts.

[0037] Since the cable drum 3 and the cable are heavy, if the rotating shaft 12 is not effectively fixed, it may fall off due to uneven force or improper operation, causing safety hazards. The limit cover 14 is sleeved on both ends of the rotating shaft 12 and bolted to the bracket 11 to form a stable protective structure, ensuring the stability and safety of the rotating shaft 12.

[0038] In one embodiment, both ends of the rotating shaft 12 are provided with an annular limiting groove 16, and the annular limiting groove 16 is adapted to the roller 13. It provides a precise positioning and fixing point for the roller 13. When the roller 13 is installed on both sides of the bottom of the rotating shaft 12 and is rotatably connected with the bracket 11, a part of the roller 13 will be embedded in the annular limiting groove 16. In this way, the roller 13 can be stably rotated under the guidance of the rotating shaft 12 without deviation or shaking, which helps to maintain the stability and balance of the cable drum 3 during the rotation process.

[0039] In one embodiment, a rotating member 4 is also included, and the rotating member 4 includes a fixed seat 41 and a turntable 42. The bottom of the turntable 42 is rotatably connected to the fixed seat 41, and the top of the turntable 42 is detachably connected to the bracket 11. In this embodiment, a groove is opened on the top of the turntable 42, which is adapted to the bottom of the bracket 11 and is connected with high-strength bolts. The design of the rotating member 4 enables the bracket 11 (as well as the rotating shaft 12, the cable drum 3, etc. installed on the bracket 11) to rotate around the fixed seat 41. This rotational freedom greatly enhances the flexibility of the device, allowing the operator to adjust the laying direction and angle of the cable according to actual needs. Whether it is straight laying or curved laying, it can be achieved by adjusting the rotation angle of the bracket 11.

[0040] In one embodiment, the fixed seat 41 includes a seat body 411 and a rotating frame 412, the rotating frame 412 is rotatably connected to the seat body 411 and detachably connected to the turntable 42, and a motor 43 is installed in the seat body 411, and the motor 43 is used to drive the turntable 42 to rotate. In an embodiment, the output shaft of the motor 43 is spline-connected to the rotating frame 412. The motor 43 is installed in the seat body 411, and the rotating frame 412 is detachably connected to the turntable 42. The motor 43 directly drives the rotating frame 412 to rotate through the spline connection. This design makes the entire drive system easy to maintain and upgrade. When the motor 43 or the rotating frame 412 fails, it can be easily removed for repair or replacement.

[0041] In one embodiment, both ends of the rotating shaft 12 are provided with a limit ring 5, and the limit ring 5 includes a circular ring portion 51 and a fastening portion 52, the circular ring portion 51 is connected to the rotating shaft 12 by a clamp, and the fastening portion 52 is threadedly connected to the circular ring portion 51. The length and diameter of the cable drum 3 will change according to the actual type of communication cable. After the staff puts the cable drum 3 on the rotating shaft 12, they install two limit rings 5 ​​from both ends of the rotating shaft 12, adjust the cable drum 3 to a suitable position, fix the two limit rings 5 ​​on the rotating shaft 12 by a clamp, and then rotate the fastening portion 52 of the limit ring 5 to be close to the end face of the cable drum 3, and the cable drum 3 is fixed.

[0042] This design can adapt to cable reels 3 of different specifications and ensure their stable rotation, which improves the flexibility and versatility of the equipment, reduces maintenance costs and improves work efficiency

[0044] S1: According to the number of cable drums 3 to be installed at the same time, a corresponding number of support members 1 are selected, and two adjacent support members 11 are connected by high-strength bolts. After multiple support members 1 are connected end to end in sequence, the installation frame 21 is installed on the first or last end of the support 11 to form a support frame with adjustable length. Finally, multiple support members 11 are installed on the turntable 42.

[0045] In actual use, the base can be buried underground, that is, according to the design requirements, a hole of appropriate size is dug at the designated location to ensure that the shape, size and depth of the hole meet the requirements for the burial of the base. At the same time, the sundries and gravel in the hole are cleaned to ensure that the base can be placed stably, and the base is placed in the hole. This can prevent the device from shaking or tilting due to vibration or external force during use.

[0046] S2: Pass the rotating shaft 12 through the inner ring of the cable drum 3 with the communication cable, and put the limit ring 5 on both ends of the rotating shaft 12. Move the limit ring 5 inward until the fastening part 52 of the limit ring 5 contacts the cable drum 3, then tighten the clamp on the annular part 51, and then rotate the fastening part 52 to press against the cable drum 3, so that the limit ring 5 is fixed on the rotating shaft 12. Then install the cable drum 3 inside the bracket 11, that is, lift and move the cable drum 3 and the rotating shaft 12, so that the two ends of the rotating shaft 12 are located in the installation openings 15 on both sides of the bracket 11, so that the two ends of the rotating shaft 12 are placed on multiple rollers 13, and the annular limit grooves 16 on the rotating shaft 12 are adapted to the rollers 13. Finally, the limit cover 14 is put on both ends of the rotating shaft 12, and the limit cover 14 is connected to the bracket 11 by high-strength bolts. Repeat this step for multiple cable drums 3, so that the cable drum 3 is installed on the corresponding support 1.
