Description

Technical Field

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

[0002] Cable laying refers to the construction process of pulling cables from cable reels and laying them to designated locations according to pre-designed paths and requirements, using specific techniques and methods. It is of great significance. In power systems, much like blood vessels transporting blood in the human body, cable laying establishes channels for power transmission, ensuring the stable and efficient delivery of electricity from the generation end to various power-consuming terminals, meeting the electricity needs of production and daily life. In the field of communications, it acts as a highway for information transmission, providing reliable guarantees for data and signal transmission, enabling the rapid and accurate dissemination of information. Furthermore, proper cable laying can effectively reduce power loss and failure rates, improve the safety and stability of system operation, reduce subsequent maintenance costs, and ensure the long-term stable operation of the entire infrastructure.

[0003] In cable laying operations, construction workers often use various cable laying equipment such as cable laying rollers and cable conveyors. Existing cable laying roller frames are mostly through-shaft structures. For example, Chinese invention patent CN117049264A discloses a cable take-up and lay-down frame. When replacing the cable laying rollers in this type of cable take-up and lay-down frame, manual tools are required to remove the shaft to separate the cable laying rollers from the frame. This replacement process is cumbersome, wastes manpower, and is slow, reducing the efficiency of cable laying operations. Furthermore, existing cable conveyors are mostly tracked. For example, Chinese invention patent CN118666084A discloses a cable conveyor that clamps the cable with tracks on both sides. When the tracks rotate, the cable is conveyed. This type of cable conveyor has poor cable restraint; during conveying, the clamped portion of the cable easily detaches from the gap between the two tracks. Moreover, this type of cable conveyor has a complex structure and usually requires two motors to operate. Utility Model Content

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: Please see Figures 1-6The cable laying device includes a moving mechanism 1 and a cable feeding mechanism 4. The moving mechanism 1 includes a moving platform 101, on which a moving wheel 102 is rotatably connected. A support frame 103 is fixed on the moving wheel 102. A shaft 104 is rotatably connected to the top of the support frame 103. A hydraulic pump station 105 is fixed on the moving platform 101. An installation groove 106 is also provided on the moving platform 101. A slide rail 107 is also fixed on the moving platform 101. Through the moving platform 101 and the moving wheel 102, the operator can easily move the device. The hydraulic pump station 105 can provide power to the hydraulic cylinder of the device. A storage battery is also fixed inside the hydraulic pump station 105 to power the hydraulic pump station 105 and the motor.

[0016] like Figure 1 , Figure 3 and Figure 4 As shown, a cable laying mechanism 2 for laying cables is rotatably connected to the moving mechanism 1. The cable laying mechanism 2 includes a cable laying roller 201 inserted into a shaft 104. Reinforcing frames 202 are provided on both sides of the cable laying roller 201. A shaft hole 203 is opened in the center of the reinforcing frame 202. The shaft 104 is inserted into the shaft hole 203 on one side of the cable laying roller 201. The cable to be laid can be wound on the cable laying roller 201. The reinforcing frame 202 can improve the load-bearing capacity of the cable laying roller 201 and prevent deformation and damage. A movable frame assembly 3 for assisting in replacing the cable roller is slidably provided on the moving mechanism 1. The movable frame assembly 3 includes a hydraulic cylinder 301 fixed in the mounting groove 106. The output end of hydraulic cylinder 301 is fixedly connected to a movable frame 302. The bottom end of the movable frame 302 is provided with a slide groove 303. The top end of the movable frame 302 is fixed with a bearing 304. The inner ring of the bearing 304 is fixed with a shaft 305. The slide groove 303 is slidably connected to the slide rail 107. When hydraulic cylinder 301 extends, the movable frame 302 will slide along the slide rail 107, thereby increasing the distance between the movable frame 302 and the upright frame 103. At this time, the wire feeding mechanism 2 can be removed from the upright frame 103. When the operator needs to replace the wire feeding mechanism 2, the lifting device can be used to lift the wire feeding mechanism 2, and then hydraulic cylinder 301 can be opened to quickly remove and replace the wire feeding mechanism 2.

[0017] like Figure 1 and Figure 5 As shown, a wire feeding mechanism 4 is fixed on the moving mechanism 1. The wire feeding mechanism 4 includes a base plate 401 fixed on the moving platform 101, and a mounting bracket 402 is fixed on the base plate 401. Mounting brackets 402 are arranged in pairs; each mounting bracket 402 has support holes; a wire feeding wheel 403 is rotatably connected to the support holes of the mounting bracket 402, with both ends of the wire feeding wheel 403 extending out of the support holes; a pulley 404 is provided at the end of the wire feeding wheel; adjacent pulleys 404 are sequentially connected by a belt 407, and the wire feeding wheels 403 form a synchronous pulley group by the belt; a reducer 405 is also provided on the mounting bracket 402, with the output shaft of the reducer 405 connected to the wire feeding wheel 403; the input shaft of the reducer 405 is connected to the output shaft of the wire feeding motor 406.

[0018] There are four wire feeding wheels 403. The two middle wire feeding wheels 403 have pulleys fixed at both ends. The first wire feeding wheel 403 and the last wire feeding wheel 403 have pulleys fixed on one side. When the wire feeding motor 406 is turned on, the wire feeding motor 406 drives the first wire feeding wheel 403 to rotate through the reducer 405. The first wire feeding wheel 403 can drive each wire feeding wheel 403 to rotate synchronously through the pulley 404 and the belt 407.

[0019] like Figure 1 and Figure 6 As shown, the moving mechanism 1 is also fixed with a wire pressing mechanism 5 for pressing cables. The wire pressing mechanism 5 includes a gantry frame 501 fixed on the moving platform 101. A hydraulic cylinder 502 is fixed to the top of the gantry frame 501. The piston rod of the hydraulic cylinder 502 passes through the top of the gantry frame 501. The front end of the piston rod of the hydraulic cylinder 502 is connected to the pressure plate. Two guide rods 504 are fixed on both sides of the top piston rod of the pressure plate 503. Multiple wire pressing wheels 505 are rotatably connected to the bottom end of the pressure plate 503. The wire pressing wheels 505 and the wire feeding wheels 403 are distributed in an alternating manner. The vertical projection position of the wire pressing wheels 505 is aligned with the gap between two adjacent wire feeding wheels 403. When the pressure plate 503 presses down, the wire pressing wheels 505 will press down into the gap between the wire feeding wheels 403. The wire pressing wheels 505 and the wire feeding wheels 403 are both covered with a rubber layer, and the shape of the wire pressing wheels 505 and the wire feeding wheels 403 is thinner in the middle and thicker at both ends. The device is nearly dumbbell-shaped. When the pressure roller 505 and the feed roller 403 press down on the cable, the expanded portions at both ends of the pressure roller 505 and the feed roller 403 can block the cable, thereby preventing the cable from slipping or coming off. When the operator uses this device to lay the cable, the cable is pulled onto the feed roller 403, and then the hydraulic cylinder 2 502 is activated. At this time, the hydraulic cylinder 2 502 pushes the pressure plate 503 and the pressure roller 505 down, and the pressure roller 505 and the feed roller 403 can clamp the cable together. At this time, the operator starts the feed motor 406, and the feed roller 403 will rotate and feed the cable. The staggered distribution of the pressure roller 505 and the feed roller 403 can effectively increase the friction between the cable and the mechanism, preventing the cable from slipping. A guide sleeve 506 is fixed on the gantry frame 501, and the guide rod 504 is slidably connected to the gantry frame 501 through the guide sleeve, which can ensure the stability of the pressure plate 503 during the lifting process.

[0020] When in use, the worker moves the device to the cable laying site using the moving mechanism 1, and releases the cable using the cable laying mechanism 2, the cable feeding mechanism 4 and the cable pressing mechanism 5, thereby assisting in cable laying. When the cable laying mechanism 2 needs to be replaced, the worker can replace it using the movable frame assembly 3.

[0021] This utility model cable laying device allows workers to easily move the device via a mobile platform and wheels. A hydraulic pump station provides power to the device's hydraulic cylinders, and a battery is also installed inside the pump station to power the pump station and motor. When the piston rod of the hydraulic cylinder extends, the movable frame slides along the slide rail, increasing the distance between the movable frame and the upright. At this time, the cable laying mechanism can be removed from the upright. When workers need to replace the cable laying mechanism, a hoisting device can be used to hold the mechanism, and then the hydraulic cylinder can be activated to quickly remove and replace the cable laying mechanism.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
