[0003] Currently, during the cable laying process inside large communication pipelines, the relatively spacious interiors allow construction workers to enter for cable laying and maintenance. However, for smaller communication pipelines, the smaller dimensions not only prevent workers from entering but also hinder the manual drilling and laying of cables, making cable laying inside them more difficult. Therefore, a cable laying device for communication pipelines is proposed to address these issues. Utility Model Content

[0012] As a further supplement to this solution, a vertical plate is fixedly connected to the bottom inner wall of the box, and the end of the second rotating column away from the inner wall of the box is rotatably connected to the vertical plate.
[0013] As a further supplement to this solution, a second gear disk is fixedly connected to the outer circumference of the second rotating column, the second gear disk meshes with a first gear disk, the first rotating column is fixedly connected to the first gear disk, and the diameter of the first gear disk is larger than the diameter of the second gear disk.

[0016] In summary, the technical effects and advantages of this utility model are as follows:
[0017] 1. This utility model enables automatic cable laying, facilitating the laying of cables inside small and medium-sized communication pipelines by workers, greatly improving the efficiency of cable laying inside pipelines, and meeting people's usage needs. At the same time, during the laying process, since the cross-section of the four sets of rollers is an isosceles trapezoid and the four sets of rollers are in close contact with the inner circumference of the pipe body, it can not only effectively increase the friction between the rollers and the pipe body, enabling the device to move stably, but also prevent the device from tilting or leaning during horizontal movement, ensuring the stability of the device during the cable laying process inside the communication pipeline.
[0018] 2. In this utility model, the stabilization component allows the two sets of movable plates to be pushed before the device is placed inside the tube. This causes the two sets of movable plates to move closer to each other. At this time, the springs fixedly connected to one side of the movable plates are stretched. Then, the worker places the entire device inside the tube, and the stretched springs immediately return to their original position. This allows the two sets of movable plates to move away from each other until the stabilizing wheel presses against the inner wall of the tube. This ensures the vertical stability of the device during its movement inside the tube and achieves a good stabilization effect. Attached Figure Description

[0026] 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.
[0027] Example: Reference Figures 1-5 The device shown is for laying communication pipelines and includes a housing 1. The outer walls of both sides of the housing 1 are rotatably connected to first rotating columns 9. Both ends of the first rotating columns 9 extend to the outside of the housing 1. Both ends of the first rotating columns 9 are fixedly connected to rotating shafts 20. One end of the rotating shafts 20 is fixedly connected to a roller 2. The inside of the housing 1 is fixedly connected to partitions 19. There are two sets of partitions 19. The two sets of partitions 19 and the inner wall of the housing 1 form a storage cavity. The inside of the storage cavity is fixedly connected to a battery pack 18.
[0028] The housing 1 is equipped with a drive assembly for rotating the first rotating column 9.
[0029] A stabilization assembly is installed on the top of housing 1;
[0030] A control panel 8 is fixedly connected to the top outer wall of the housing 1;
[0031] One end of the housing 1 is fixedly connected to a connecting seat 3, and a connecting rope 4 is provided on one side of the connecting seat 3. By tying the connecting rope 4 to the communication cable to be laid, the cable can be automatically laid, which facilitates the laying of cables inside small and medium-sized communication pipelines by the staff, greatly improves the laying efficiency of cables inside the pipeline, and meets people's needs.
[0032] Preferably, there are four sets of rollers 2, and the cross-section of the four sets of rollers 2 is an isosceles trapezoid. The outer circumference of the rollers 2 is in contact with the inner circumference of the tube 27, which can effectively increase the friction between the rollers 2 and the tube 27, enabling the device to move stably. At the same time, it can also prevent the device from tilting or leaning during horizontal movement, thus ensuring the stability of the device during the laying of cables inside the communication pipeline.
[0033] Preferably, the drive assembly includes a motor 15 fixedly connected to the inner wall of the top of the housing 1. A third rotating column 13 is fixedly connected to the output end of the motor 15. A first helical gear 14 is fixedly connected to the outer circumference of the third rotating column 13. The first helical gear 14 meshes with a second helical gear 16. A second rotating column 12 is fixedly connected to the inner circumference of the second helical gear 16. One end of the second rotating column 12 is rotatably connected to the inner wall of one side of the housing 1. A vertical plate 17 is fixedly connected to the inner wall of the bottom of the housing 1. The end of the second rotating column 12 away from the inner wall of the housing 1 is rotatably connected to the vertical plate 17. By starting the motor 15, the third rotating column 13 can be driven to rotate. The third rotating column 13 drives the first helical gear 14 to rotate. Through the meshing of the first helical gear 14 and the second helical gear 16, the second rotating column 12 can be driven to rotate by the rotation of the second helical gear 16.
[0034] Preferably, a second gear disk 11 is fixedly connected to the outer circumference of the second rotating column 12. The second gear disk 11 meshes with the first gear disk 10. The first rotating column 9 is fixedly connected to the first gear disk 10. The diameter of the first gear disk 10 is larger than the diameter of the second gear disk 11. The rotation of the second rotating column 12 can drive the second gear disk 11 to rotate. At the same time, the second gear disk 11 and the first gear disk 10 mesh with each other, thereby driving the first gear disk 10 to rotate. When the first gear disk 10 rotates, it can drive the first rotating column 9 to rotate, thereby providing rolling power to the roller 2. At the same time, the diameter of the first gear disk 10 is larger than the diameter of the second gear disk 11, which can play a good deceleration effect and avoid the roller 2 from rotating too fast and becoming unstable.
[0035] Preferably, the stabilization component includes a housing 5 fixedly connected to the top outer wall of the housing 1. A fourth rotating column 25 is rotatably connected to both inner walls of the housing 5. A rotating sleeve 24 is fixedly connected to the outer circumference of the fourth rotating column 25. A movable plate 23 is fixedly connected to the outer circumference of the rotating sleeve 24. A connecting block 21 is fixedly connected to one end of the movable plate 23 away from the rotating sleeve 24. A rotating shaft 22 is fixedly connected to both ends of the connecting block 21. A stabilizing wheel 7 is rotatably connected to one end of the rotating shaft 22. The outer circumference of the stabilizing wheel 7 contacts the inner circumference of the tube 27. A through groove 6 is provided on the top outer wall of the housing 5. One end of the movable plate 23 passes through the inside of the through groove 6. A spring 2 is fixedly connected to one outer wall of the movable plate 23. 6. The end of the spring 26 away from the movable plate 23 is fixedly connected to the top inner wall of the housing 5. Before the operator places the device inside the tube 27, the two sets of movable plates 23 can be pushed first to move the two sets of movable plates 23 closer to each other. At this time, the spring 26 fixedly connected to one side of the movable plate 23 will be in a stretched state. Then the operator puts the entire device into the tube 27. The stretched spring 26 will immediately return to its original state, so that the two sets of movable plates 23 can move away from each other until the stabilizing wheel 7 is pressed against the inner wall of the tube 27. This ensures the vertical stability of the device during the movement inside the tube 27 and achieves a good stabilization effect.
[0036] The working principle of this utility model is as follows: Before placing the device inside the pipe body 27, the two sets of movable plates 23 can be pushed to move them closer to each other. At this time, the spring 26 fixedly connected to one side of the movable plate 23 will be in a stretched state. Then, the worker puts the entire device into the pipe body 27. Subsequently, the stretched spring 26 will immediately return to its original state, thereby allowing the two sets of movable plates 23 to move away from each other until the stabilizing wheel 7 presses against the inner wall of the pipe body 27. This ensures the vertical stability of the device during its movement inside the pipe body 27, achieving a good stabilization effect. During the installation process, since the cross-section of the four sets of rollers 2 is an isosceles trapezoid and all four sets of rollers 2 are in close contact with the circumferential inner wall of the pipe body 27, it can not only effectively increase the friction between the rollers 2 and the pipe body 27, enabling the device to move stably, but also prevent the device from tilting or leaning during horizontal movement, ensuring the stability of the device during the cable laying process inside the communication pipeline.
