Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable laying guidance technology, and in particular to a retractable underground cable laying guide frame. Background Technology
[0002] With the acceleration of urbanization and the continuous improvement of urban infrastructure such as electricity and communications, the scale and number of underground cable laying projects are also growing. The laying environment of underground cables is complex and diverse, requiring them to cross various pipes of different diameters and directions, such as urban underground utility tunnels and cable trays inside buildings.
[0003] Traditional cable laying guide frames are relatively fixed in design and difficult to adapt to complex and changing environments. When encountering inclined slopes, their lack of structural flexibility and adaptability fails to provide proper cable guidance, leading to cable friction and collisions with the guide frame, resulting in jamming. This not only reduces construction efficiency but also requires more manpower to resolve the jamming issue, increasing construction difficulty and costs. Moreover, cables may be damaged during jamming, affecting their lifespan and performance, posing safety hazards to subsequent power or communication transmission. Therefore, we propose a retractable underground cable laying guide frame to solve these problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a retractable underground cable laying guide frame.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A retractable underground cable laying guide frame includes a base plate. A carrier box is fixed to the upper center of the base plate. A sliding groove is provided on one side of the carrier box, and a buffer mechanism is provided in the sliding groove. An installation rod is detachably connected to the upper end of the buffer mechanism. The upper end of the installation rod passes through the side wall of the carrier box and extends to the upper end of the carrier box. A U-shaped support frame is rotatably connected to the upper end of the installation rod. A stud is threaded onto the buffer mechanism. Both sides of the stud pass through the two end side walls of the carrier box and extend to the two sides of the carrier box. Support rods are movably installed at both ends of the stud. Multiple through holes are provided at equal intervals along the vertical direction on the support rod. A U-shaped auxiliary conveyor frame is rotatably connected to the upper end of the support rod. A conveyor roller is rotatably connected to the U-shaped auxiliary conveyor frame.
[0007] The buffer mechanism includes a first slider and a second slider installed in a slide groove. Two springs are connected between the first slider and the second slider. Two dampers are installed at the bottom of the slide groove, and the upper ends of the dampers are connected to the lower ends of the second slider.
[0008] The first slider has a threaded through hole in the middle, and the stud is threaded through the threaded through hole. The carrier box has openings on both sides, and the two ends of the stud pass through the openings and extend to both sides of the carrier box.
[0009] The stud passes through one of the through holes on a support rod on the same side, and multiple nuts are threaded onto the stud. Two nuts on the same side abut against the two ends of a support rod on the same side.
[0010] Mounting holes are provided at the four corners of the upper end of the base plate.
[0011] The U-shaped support frame is provided with a flexible layer.
[0012] In this utility model, when performing auxiliary traction:
[0013] 1. Installation preparation: When cable laying and traction are required at the ramp location, first, according to the actual construction location, install and fix the entire guide frame in the corresponding position through the mounting holes on the base plate to ensure the stability of the guide frame.
[0014] 2. Inclination Adjustment: Based on the inclination of the ramp, insert one end of the stud into the corresponding through hole on the support rod to adjust its height. By selecting different through holes, the two U-shaped auxiliary conveyor frames and one U-shaped support frame can be arranged in different inclination patterns to adapt to cable conveying on an incline. If conveying on flat ground, the position of the stud can be adjusted to make the two U-shaped auxiliary conveyor frames and one U-shaped support frame arranged in parallel, improving the stability and smoothness of the conveying.
[0015] 3. Spacing adjustment: According to the load-bearing requirements of the cable, the spacing between the U-shaped auxiliary conveyor frame and the U-shaped support frame can be adjusted by adjusting the position of the stud in the through hole to ensure the firmness and stability of the load-bearing capacity;
[0016] 4. Cable conveying: After completing the above adjustments, place the cable on the U-shaped auxiliary conveyor frame and the U-shaped support frame. The cable is conveyed by the rotation of the conveyor rollers. The flexible layer on the U-shaped support frame can reduce the friction between the cable and the support frame and protect the cable surface.
[0017] 5. Buffering and shock absorption: During cable transportation, when encountering vibration or impact, the buffering mechanism starts to work. The first and second sliders slide in the groove, and the spring and damper work together to buffer and absorb vibration and impact, further improving the stability of the transportation.
[0018] This utility model has the following advantages:
[0019] 1. The retractable underground cable laying guide frame can be flexibly adjusted according to different laying environments and cable routes, avoiding cable jamming at inclined slopes, making cable transportation smoother and greatly improving construction efficiency.
[0020] 2. The guide frame can adapt to pipes of different diameters and directions, as well as various laying environments such as inclined and horizontal, and has strong adaptability;
[0021] 3. By adjusting the inclination and spacing of the U-shaped auxiliary conveyor frame and the U-shaped support frame, as well as the buffering and shock absorption effect of the buffer mechanism, the stability and firmness of the cable conveying are ensured, and safety hazards are reduced.
[0022] 4. By combining two conveyor rollers and a flexible layer, the smoothness of conveying is improved, the damage to the cable during the conveying process is reduced, and the service life of the cable is extended.
[0023] In summary, this utility model avoids cable jamming at inclined slopes, making cable transport smoother and greatly improving construction efficiency. It can also adapt to pipes of different diameters and orientations, as well as various laying environments such as inclined and horizontal, demonstrating strong adaptability. Furthermore, it can improve the smoothness of transport, reduce damage to cables during transport, ensure the stability and firmness of cable transport, and reduce safety hazards.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Reference Figure 1-4 The retractable underground cable laying guide frame includes a base plate 7. A bearing box 8 is fixed in the middle of the upper end of the base plate 7. A slide groove 18 is provided on one side of the bearing box 8. A buffer mechanism is provided in the slide groove 18. An installation rod 10 is detachably connected to the upper end of the buffer mechanism. The upper end of the installation rod 10 passes through the side wall of the bearing box 8 and extends to the upper end of the bearing box 8. A U-shaped support frame 3 is rotatably connected to the upper end of the installation rod 10. A stud 11 is threaded onto the buffer mechanism. The two sides of the stud 11 pass through the two end side walls of the bearing box 8 and extend to the two sides of the bearing box 8. Support rods 5 are movably installed at both ends of the stud 11. Multiple through holes 13 are provided at equal intervals along the vertical direction on the support rods 5. When selecting the through holes 13, the inclination angle of the ramp must be accurately measured. The appropriate through holes 13 are selected according to the angle to ensure that the two U-shaped auxiliary conveying frames 1 and one U-shaped support frame 3 form a high-low arrangement that adapts to the inclination of the ramp, so that the cable can be smoothly conveyed in the inclined state.
[0031] The upper end of the support rod 5 is rotatably connected to a U-shaped auxiliary conveyor frame 1, and a conveyor roller 4 is rotatably connected to the U-shaped auxiliary conveyor frame 1. The conveyor roller 4 can reduce friction during cable conveying, making cable conveying smoother.
[0032] The buffer mechanism includes a first slider 14 and a second slider 15 installed in the slide 18. Two springs 16 are connected between the first slider 14 and the second slider 15. Two dampers 17 are installed at the bottom of the slide 18. The upper end of the damper 17 is connected to the lower end of the second slider 15. The spring 16 is elastic and can deform when subjected to vibration or impact, thus playing a preliminary buffering role. The damper 17 can gradually dissipate the energy stored in the spring 16, further enhancing the buffering effect and ensuring the stability of cable transmission.
[0033] The first slider 14 has a threaded through hole in the middle, and the stud 11 is threaded through the threaded through hole. Both sides of the carrier box 8 have openings 9. The two ends of the stud 11 pass through the openings 9 and extend to both sides of the carrier box 8, so that the stud 11 can move stably in the carrier box 8 and facilitate connection with the support rod 5.
[0034] The stud 11 passes through one of the through holes 13 on a support rod 5 on the same side. Multiple nuts 12 are threaded onto the stud 11. Two nuts 12 on the same side abut against the two ends of a support rod 5 on the same side. By tightening or loosening the nuts 12, the position of the support rod 5 can be fixed or adjusted, thereby realizing the height and telescopic adjustment of the guide frame.
[0035] Mounting holes 6 are provided at the four corners of the upper end of the base plate 7. The mounting holes 6 are used to install and fix the entire guide frame in the construction position to ensure that the guide frame will not be displaced during operation. Expansion bolts are used for installation.
[0036] The U-shaped support frame 3 is provided with a flexible layer 2, which can be made of soft materials such as rubber, which can effectively reduce the friction between the cable and the support frame and protect the cable surface from damage.
[0037] In this utility model, when performing auxiliary traction:
[0038] 1. Installation preparation: When cable laying and traction are required at the ramp location, first, according to the actual construction location, install and fix the entire guide frame in the corresponding position through the mounting holes 6 on the base plate 7 to ensure the stability of the guide frame.
[0039] 2. Inclination Adjustment: Based on the inclination of the ramp, insert one end of the stud 11 into the corresponding through hole 13 on the support rod 5 to adjust its height. By selecting different through holes 13, the two U-shaped auxiliary conveyor frames 1 and the U-shaped support frame 3 can be arranged in different inclination patterns to adapt to cable conveying on an incline. If conveying is carried out on flat ground, the position of the stud 11 can be adjusted so that the two U-shaped auxiliary conveyor frames 1 and the U-shaped support frame 3 are arranged in parallel, improving the stability and smoothness of the conveying.
[0040] 3. Spacing adjustment: According to the load-bearing requirements of the cable, the spacing between the U-shaped auxiliary conveyor frame 1 and the U-shaped support frame 3 can be adjusted by adjusting the position of the stud 11 in the through hole 13 to ensure the firmness and stability of the load-bearing.
[0041] 4. Cable conveying: After completing the above adjustments, place the cable on the U-shaped auxiliary conveyor frame 1 and the U-shaped support frame 3. The cable is conveyed by the rotation of the conveyor roller 4. The flexible layer 2 on the U-shaped support frame 3 can reduce the friction between the cable and the support frame and protect the cable surface.
[0042] 5. Buffering and shock absorption: During cable transportation, when encountering vibration or impact, the buffering mechanism starts to work. The first slider 14 and the second slider 15 slide in the groove 18. The spring 16 and the damper 17 work together to buffer and absorb vibration and impact, further improving the stability of the transportation.
[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
