Description

Technical Field

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

[0002] Cables are conductor assemblies used to transmit electrical energy, signals, or data, and are widely used in power, communications, transportation, construction, and other fields. During cable laying, cable laying racks are typically used to support and guide the cables, ensuring their smooth placement in the designated location. Cable laying racks not only reduce frictional resistance during cable laying, preventing cable damage, but also improve the efficiency and safety of the laying work, ensuring construction quality. Therefore, cable laying racks play a crucial auxiliary role in cable laying projects.

[0003] Existing cable laying racks typically employ roller structures or bracket supports to assist in cable laying. For example, some racks have multiple rollers on the frame to reduce frictional resistance during cable laying and improve wiring efficiency through roller rotation; others use V-shaped or U-shaped support structures to stably place cables on the brackets, preventing tangling or damage during laying. However, in some existing cable laying racks, the connection between the rollers and the brackets is quite secure, requiring the cables to be pre-wound onto the rollers before moving the equipment to assist in cable laying, which is cumbersome and affects work efficiency. Therefore, a new cable laying rack for assisting cable laying is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cable laying frame for auxiliary cable laying, which aims to improve the problem of the existing technology where the roller is fixed and the cable is not easy to replace quickly after laying.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[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. 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.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a cable laying frame for auxiliary cable laying, including a trolley 1, a motor 2 fixedly connected to the side wall of the trolley 1, a fixed plate 3 fixedly connected to the output end of the motor 2, a roller 4 provided on the top of the trolley 1, a positioning hole 5 opened on one side of the roller 4, the side wall of the fixed plate 3 slidably connected to the positioning hole 5, a quick-installation mechanism provided on the top of the trolley 1, and a pressing mechanism provided on the top of the trolley 1; the quick-installation mechanism includes a screw 9, a bearing 10 and a locking block 11, a fixed frame 7 fixedly connected to the top of the trolley 1, a rotating plate 8 rotatably connected inside the fixed frame 7, the screw 9 threadedly connected to the inside of the rotating plate 8, the inner ring of the bearing 10 fixedly connected to the side wall of the screw 9, the locking block 11 fixedly connected to the outer ring of the bearing 10, a groove 6 opened on the other side of the roller 4, the locking block 11 slidably connected to the inside of the groove 6, and a handle 12 fixedly connected to the end of the screw 9 away from the roller 4;

[0031] When installing the roller 4, first align the positioning hole 5 inside the roller 4 with the fixing plate 3. After alignment, insert the fixing plate 3 into the positioning hole 5 so that it fits tightly against the roller 4, thus achieving initial fixation of the roller 4 and providing basic support for subsequent installation. Next, by flipping the rotating plate 8, it is deflected in the fixing frame 7. When the locking block 11 is aligned with the groove 6, by rotating the handle 12, the screw 9 is moved along the set trajectory, so that the locking block 11 is gradually embedded into the groove 6. This not only fixes the roller 4 a second time, but also effectively prevents the equipment from loosening or shifting due to vibration or external force during operation, thereby improving the reliability of installation and the safety of equipment operation.

[0032] Reference Figure 1 and Figure 4 The pressing mechanism includes a sleeve 14, a slide rod 15, and a pressure plate 18. A side plate 13 is fixedly connected between the trolley 1 and the fixed frame 7. The side wall of the sleeve 14 is fixedly connected to the side wall of the side plate 13. The slide rod 15 is slidably connected inside the sleeve 14. The side wall of the pressure plate 18 is fixedly connected to the side wall of the slide rod 15. A spring 17 is installed inside the sleeve 14. One end of the spring 17 is fixedly connected inside the sleeve 14, and the other end of the spring 17 is fixedly connected to the side wall of the slide rod 15. A motor 19 is fixedly connected to the side wall of the trolley 1. A vertical plate 20 is fixedly connected to the top of the trolley 1. The output end of motor 19 is fixedly connected to a lead screw 21, which is rotatably connected to the side wall of the upright plate 20. A guide rod 22 is fixedly connected between the trolley 1 and the upright plate 20. A sliding frame 23 is slidably connected to the side wall of the guide rod 22. The sliding frame 23 is threadedly connected to the side wall of the lead screw 21. A limit ring 16 is fixedly connected to the top of the sliding frame 23. When motor 19 is started, the lead screw 21 will rotate, and the sliding frame 23 will reciprocate under the restriction of the guide rod 22 to guide the cable and prevent the cable from twisting and tangling during the cable laying process.

[0033] After the roller 4 is installed, the cable wound on the roller 4 will apply a certain squeezing force to the pressure plate 18, so that the slide bar 15 on its rear side will slide smoothly into the sleeve 14 along the guide direction. At the same time, it will compress the spring 17. As the spring 17 is gradually compressed, the elastic potential energy accumulated inside it will increase and provide a reaction force, thereby effectively supporting the pressure plate 18 and keeping it in close contact with the outer surface of the cable. This continuous contact force can prevent the cable from shifting or becoming unevenly wound due to loosening.

[0034] Working principle: When installing roller 4, first align the positioning hole 5 inside roller 4 with the fixing plate 3, then insert the fixing plate 3 into the positioning hole 5 to pre-fix roller 4. Then, rotate the rotating plate 8 to make it deflect in the fixing frame 7. When the locking block 11 is aligned with the groove 6, rotate the handle 12 to drive the screw 9 to move and gradually insert the locking block 11 into the groove 6, thus fixing the position of roller 4 again and completing the installation of roller 4. After the roller 4 is installed, the cable wound on roller 4 will squeeze the pressure plate 18, causing the slide rod 15 on its rear side to slide into the sleeve 14 and activate the spring 17. The cable is compressed, and the reaction force of the spring 17 supports the pressure plate 18, keeping it in close contact with the outside of the cable to prevent it from loosening. When using the equipment for cable laying, one end of the cable is passed through the inside of the limiting ring 16, and then the worker holds this end of the cable and walks forward to lay the cable. While walking, motor 12 and motor 29 are started at the same time. Motor 12 drives the fixed plate 3 to rotate, which in turn drives the roller 4 to perform the cable laying operation. Motor 29 drives the lead screw 21 to rotate, which causes the sliding frame 23 to move back and forth to guide the cable and prevent the cable from twisting and tangling.

[0035] 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.
