Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a cable laying device for tunnel construction. Background Technology

[0002] Cables used in tunnel construction mainly include power cables (including high-voltage and low-voltage power cables, used for long-distance transmission of high-power electrical energy and for powering small equipment at close range, respectively), communication cables (used for communication signal transmission within the tunnel), and control cables (connecting control circuits for equipment within the tunnel). Using cable laying equipment ensures safe construction, preventing cables from being crushed by construction machinery or trampled by personnel, preventing them from becoming tripping hazards for construction workers, and reducing the risk of electric shock. It also improves construction efficiency; for example, cable conveyors can quickly and accurately lay cables, facilitating coordination with other construction processes. Furthermore, it ensures the quality of cable laying, standardizes laying paths, and avoids situations such as excessively small bending radii or overlapping laying.

[0003] The existing tunnel cable laying devices are usually installed at a fixed height, which makes it impossible to adjust the height according to actual needs during use. Moreover, since the cable is wrapped around the cable frame, it may shake or even fall off the traction device during use, resulting in reduced cable laying efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cable laying device for tunnel construction, which aims to improve the problems in the prior art where the height of cable laying cannot be adjusted according to the actual situation, and where the cable sways and falls off the traction device during laying, resulting in reduced cable laying efficiency.

One end of the connecting plate is fixedly connected to one side of the outer wall of the guide ring. The guide ring is threaded with a bolt three. One end of the bolt three is fixedly connected to a pressure plate. The guide ring is fixedly connected with a spring one. One end of the spring one is fixedly connected to an auxiliary plate. The upper surface of the rotating base is slidably connected to a housing one. The housing one is fixedly connected to a spring two. One end of the spring two is fixedly connected to a connecting column. One end of the connecting column is fixedly connected to a mounting bracket.

[0006] Furthermore, the transmission assembly includes a second rotating shaft, which is rotatably connected inside the rotating base. A first motor is fixedly connected to one side of the outer wall of the rotating base. The output end of the first motor is fixedly connected to one side of the outer wall of the second rotating shaft. A gear is fixedly connected to one end of the second rotating shaft. A rack plate is slidably connected inside the rotating base. The rack plate meshes with the gear. The upper surface of the rack plate is fixedly connected to the lower surface of the outer shell.

[0007] Furthermore, a second outer shell is rotatably connected to the lower surface of the rotating base, a support base is fixedly connected to the lower surface of the second outer shell, a second motor is fixedly connected to the upper surface of the support base, the output end of the second motor is fixedly connected to the lower surface of the rotating base, a shock absorber is fixedly connected to the lower surface of the support base, a support base plate is fixedly connected to one end of the shock absorber, a caster wheel is fixedly connected to the lower surface of the support base plate, and a stabilizing component for stabilizing the device is installed inside the support base plate.

[0008] Furthermore, the stabilizing component includes a second bolt, one side of which is threaded into the interior of the support base plate.

[0009] Furthermore, the upper surface of the rotating base is fixedly connected with symmetrical support arms, and each of the two support arms is rotatably connected with a rotating shaft. A cable rack body is fixedly connected to one side of the outer wall of the rotating shaft.

[0011] Furthermore, the pressure plate and auxiliary plate are made of soft rubber, and the spring is used to protect the cable from damage due to pressure.

[0012] Furthermore, the shock absorber consists of a spring and a damping rod, and is used to absorb vibrations and shocks to protect the device from damage.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by rotating the first bolt, which is threadedly connected to the collar, the collar is driven to move vertically, thereby driving the guide ring installed between the first and second connecting plates to move in the same direction, thus achieving the effect of adjusting the erection height. Furthermore, through the meshing connection between the gear and the rack plate, the rotation of the motor realizes the lateral movement of the rack plate, which in turn realizes the lateral movement of the outer shell, achieving the effect of following the lateral swaying of the cable. This solves the problems in the prior art where the height of the cable erection cannot be adjusted according to the actual situation, and where the cable sways and falls off the traction device during erection, resulting in a reduction in cable erection efficiency, thus improving the practicality of the device.

[0015] 2. In this utility model, the rotating base driven by motor two achieves the effect of changing the direction of the line change. The use of casters and bolts two allows the device to be easily moved to different construction positions while improving its own stability and preventing positional deviation that would affect construction. This solves the problem that the erection device is difficult to move and that it is difficult to change the direction of the line change according to actual needs in the tunnel, which affects the erection efficiency and improves the practicality of the device.

[0024] 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.

[0025] Reference Figure 1 - Figure 4This utility model provides an embodiment of a cable laying device for tunnel construction, comprising a rotating base 1. In tunnel construction, due to the potentially complex shape and layout of the tunnel, the rotating base 1 can adjust the cable laying direction according to actual needs, improving construction flexibility. A mounting plate 1 (first mounting plate 5) and a mounting plate 2 (second mounting plate 6) are fixedly connected to the upper surface of the rotating base 1. A mounting column 12 is fixedly connected inside the mounting plate 15. A connecting plate 2 (second mounting plate 11) is slidably connected to one side of the outer wall of the mounting column 12. A guide ring 15 is fixedly connected to one end of the connecting plate 2 (second mounting plate 11). The guide ring 15 is a key component for cable passage; it guides the cable, ensuring it maintains the correct direction during laying and preventing entanglement or deviation. The predetermined path is rotatably connected to bolt 7 inside mounting plate 26. A collar 9 is threaded onto one side of the outer wall of bolt 7. By rotating bolt 7, collar 9 can move axially along bolt 7. A connecting plate 10 is fixedly connected to one side of the outer wall of collar 9, with one end of connecting plate 10 fixedly connected to one side of the outer wall of guide ring 15. Thus, by adjusting bolt 7, the position of guide ring 15 can be further precisely adjusted to accommodate cables of different diameters and different construction requirements. Bolt 3 13 is threaded inside guide ring 15, with a pressure plate 14 fixedly connected to one end of bolt 3 13. When the cable passes through guide ring 15, rotating bolt 3 13 causes pressure plate 14 to press the cable firmly, preventing the cable from loosening or slipping during installation. This design... The design ensures cable stability and improves the quality and safety of cable installation. A spring 17 is fixedly connected inside the guide ring 15, and an auxiliary plate 16 is fixedly connected to one end of the spring 17. The combination of spring 17 and auxiliary plate 16 acts as a buffer. When the cable passes through the guide ring 15, if the cable is subjected to external impact or vibration, spring 17 can absorb some energy, reducing damage to the cable. A housing 18 is slidably connected to the upper surface of the rotating base 1. A spring 20 is fixedly connected inside the housing 18, and a connecting post 19 is fixedly connected to one end of spring 20. A mounting bracket 21 is fixedly connected to one end of the connecting post 19. A guide roller 22 is rotatably connected inside the mounting bracket 21. The cable slides on the guide roller 22, reducing friction. To facilitate smoother cable installation, the rotating base 1 is equipped with a transmission assembly for moving the outer casing 18. The transmission assembly includes a rotating shaft 24, which is rotatably connected inside the rotating base 1. A motor 23 is fixedly connected to one side of the outer wall of the rotating base 1, and the output end of the motor 23 is fixedly connected to one side of the outer wall of the rotating shaft 24. A gear 25 is fixedly connected to one end of the rotating shaft 24. A rack plate 26 is slidably connected inside the rotating base 1 and meshes with the gear 25. The upper surface of the rack plate 26 is fixedly connected to the lower surface of the outer casing 18. Through the transmission of the gear 25 and the rack plate 26, the motor 23 can precisely control the movement of the outer casing 18, thereby adjusting the position of the guide roller 22 so that the cable will not fall when it sways.

[0026] Reference Figure 1 , Figure 5 and Figure 6 A second outer shell 28 is rotatably connected to the lower surface of the rotating base 1, allowing the rotating base 1 to adjust its angle more flexibly. A support base 27 is fixedly connected to the lower surface of the second outer shell 28, and a second motor 29 is fixedly connected to the upper surface of the support base 27. The output end of the second motor 29 is fixedly connected to the lower surface of the rotating base 1. A shock absorber 31 is fixedly connected to the lower surface of the support base 27. During cable laying, the device may be subjected to ground vibration and impact. The shock absorber 31 can effectively absorb these vibrations and impacts, protecting the various components of the device from damage. A support base plate 30 is fixedly connected to one end of the shock absorber 31, and a caster wheel 32 is fixedly connected to the lower surface of the support base plate 30. The caster wheel 32 allows the device to be easily moved to different construction positions. A stabilizing component for stabilizing the device is installed inside the support base plate 30. The stabilizing component includes a bolt 28. When the device is moved to the designated position, the bolt 28 can be rotated to stabilize the device. It extends downwards and contacts the ground, increasing the friction between the device and the ground, thereby improving the stability of the device. Bolt 28 is threaded on one side of its outer wall and connected to the inside of the support base plate 30. The upper surface of the rotating base 1 is fixedly connected to the left and right symmetrical support arms 2. The two support arms 2 are rotatably connected to the shaft 1 3 inside. The shaft 1 3 allows the cable frame body 4 to rotate, which facilitates the release and rewinding of the cable. The outer wall of the shaft 1 3 is fixedly connected to the cable frame body 4. The outer wall of the connecting column 19 is slidably connected to the inside of the outer shell 18. The outer wall of the connecting plate 2 11 is slidably connected to the inside of the mounting plate 1 5. The pressure plate 14 and the auxiliary plate 16 are made of soft rubber. The soft rubber material has a certain elasticity and friction, which can better fix the cable and avoid damage to the cable. Spring 17 is used to protect the cable from pressure damage. The shock absorber 31 is composed of a spring and a damping rod. The shock absorber 31 is used to absorb vibration and impact to protect the device from damage.

[0027] Working principle: Before using the device, place the cable on the cable rack body 4, and pull one end of the cable onto the guide roller 22. Start the motor 23, and its output end drives the rotating shaft 24 and gear 25 to rotate. The gear 25 and rack 26 are meshed, so the gear 25 drives the rack 26 to move synchronously. The upper surface of the rack 26 is fixed to the outer shell 18, so the movement of the rack 26 causes the outer shell 18 to slide on the upper surface of the rotating base 1, thus achieving the guiding effect of multi-directional cables. At the same time, the outer shell 18 is equipped with spring 20 and connecting column 19, so the guide roller 22 can move up and down with the help of connecting column 19 and spring 20, which can help the cable adapt to different height requirements. After the traction is completed, clamp the cable. First, rotate bolt 3 13 to put the cable into the guide roller. Inside the ring 15, rotate bolt 3 13 in the opposite direction to clamp the cable. Since the pressure plate 14 and auxiliary plate 16 are made of rubber, and with the buffering effect of spring 17, the cable is well protected. When it is necessary to adjust the height of the guide ring 15, i.e. the cable installation height, rotate bolt 7. Its rotation, through the threaded connection, can drive the collar 9 to move up and down, which in turn drives the connecting plate 10 and the guide ring 15 to move up and down, thus completing the adjustment of the installation height. The motor 29 can drive the rotating base 1 to rotate in the horizontal direction, so that the direction of cable replacement can be changed according to actual needs, making it more convenient to use. Multiple shock absorbers 31 are set under the support base 27 for vibration damping, and multiple bolts 2 8 can stabilize the overall device and prevent the device from sliding during installation.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
