Description

Technical Field

[0001] This utility model belongs to the field of cable installation and construction, and specifically relates to a cable laying traction device. Background Technology

[0002] With the accelerating pace of urbanization, the workload of cable laying has increased significantly. Traditionally, cable laying involves using steel wire ropes to bind and pull the cable, which can easily cause surface wear and reduce its lifespan. Existing cable laying traction devices typically use two traction rollers to hold the cable for pulling and transmission. However, at high speeds, this can lead to cable swaying, affecting traction stability. Furthermore, different cable sizes require manual adjustment when pulling different sized cables, greatly impacting the efficiency and quality of cable laying. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model aims to provide a cable laying traction device. This device can adapt to the laying and installation of cables of different sizes, and can effectively avoid the swaying problem during cable traction and transmission through the cable management component, thereby significantly improving the cable laying efficiency and the stability of device operation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cable laying traction device includes a traction assembly mounted on a movable base, on which a cable management assembly is also mounted. The traction assembly includes two parallel side plates, with a lifting frame vertically slidably mounted between the two side plates. A lifting drive mechanism for driving the lifting frame to move up and down is mounted on the side plates. Two traction wheels are vertically arranged side by side on the lifting frame, with the upper and lower ends of the traction wheels respectively mounted on an upper slider and a lower slider, both of which are horizontally slidably mounted on the lifting frame. A traction motor is mounted on one of the lower sliders, and the traction motor is poweredly connected to the corresponding traction wheel. Corresponding connecting blocks are fixed above the two upper sliders, and inclined surfaces are provided on opposite sides of the two connecting blocks, forming an inverted octagonal design. A top block is provided between the two connecting blocks, with inclined edges at both ends along the inclination direction of the two inclined surfaces and slidably connected to the corresponding inclined surfaces. A telescopic cylinder is mounted on the top of the lifting frame, with the piston rod of the telescopic cylinder vertically downward and fixed to the top block.

[0006] Preferably, the lifting drive mechanism includes a lead screw and a lifting motor vertically mounted on the outer wall of one of the side plates, the lifting motor being poweredly connected to the upper end of the lead screw; vertical slots are vertically opened on the two side plates, and the limiting blocks fixed to the side ends of the lifting frame are slidably engaged in the corresponding vertical slots; the limiting blocks near the lead screw are threaded onto the lead screw.

[0007] Preferably, a horizontal lower sliding groove is provided below the lifting frame, and two lower sliding blocks are slidably engaged in the lower sliding groove; an upper sliding groove is provided above the lifting frame, and two upper sliding blocks are slidably engaged in the upper sliding groove.

[0008] Preferably, a T-shaped groove is formed on the inclined surface of the connecting block along its inclined direction, and a T-shaped block that mates with the T-shaped groove is fixed at the end of the top block, and the T-shaped block is slidably engaged in the T-shaped groove.

[0009] Preferably, the cable management assembly includes a cable management frame and a rotating ring. The cable management frame has a horizontally opened circular cable entry hole. The rotating ring is concentrically rotatably mounted on one side of the cable entry hole and is connected to a rotation drive assembly on the cable management frame. Multiple sleeves are rotatably mounted on the rotating ring, and a movable plate is slidably fitted inside each sleeve. One end of the movable plate is rotatably connected to the cable management frame, and the other end is movably disposed at the cable entry hole. A guide roller is installed on the movable plate along its length near the cable entry hole.

[0010] Preferably, the rotary drive assembly includes a rotary drive motor and a worm gear, the worm gear being mounted on the cable management frame and powered by the rotary drive motor; the outer circumference of the rotating ring is provided with meshing teeth, and the worm gear meshes with the meshing teeth.

[0011] Preferably, the sleeves are set at equal included angles.

[0012] Preferably, an annular guide rail is concentrically installed at the threading opening, and the swivel ring is slidably mounted on the guide rail.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This application significantly improves the stability of the lifting frame when it moves up and down by sliding the limiting block with the vertical grooves on the two side plates. By using the lifting motor to drive the lead screw to rotate, the lifting frame can be moved up and down through the limiting block, thereby adjusting the height of the two traction wheels. This makes the traction space of the traction wheels correspond horizontally with the cable management assembly, enabling the device to adapt to the traction operation of cables of different diameters.

[0015] 2. This application utilizes the sliding fit between the T-slot and the T-block to improve the stability when the top block slides against the two connecting blocks; the telescopic cylinder drives the top block to move up and down, and the cooperation between the inclined surfaces of the two connecting blocks and the inclined edge of the top block can move the two connecting blocks away from or closer to each other. In turn, the upper slider drives the two traction wheels below to move synchronously, thereby adjusting the distance between the two traction wheels. This allows the device to be used for traction of cables of different diameters.

[0016] 3. When the rotary drive motor drives the worm to rotate, the meshing of the worm and the meshing teeth can drive the rotating ring to rotate synchronously. The sleeve pushes the movable plate to rotate and swing around the end hinge point, so that the guide roller installed on the movable end of the movable plate can abut against the outer wall of the cable. This allows the device to clamp cables of different diameters and effectively limit and guide the cable during cable traction and pulling. This can effectively prevent the cable from swinging back and forth at the traction wheel during the traction action, thus affecting the stability of the traction operation.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0021] like Figure 1-3 As shown, this utility model proposes a cable laying traction device, including a traction assembly, which is mounted on a movable base 1. A cable management assembly is also mounted on the movable base 1. The traction assembly includes two parallel side plates 3, with a lifting frame 4 vertically slidably mounted between the two side plates 3. A lifting drive mechanism for driving the lifting frame 4 to move up and down is mounted on the side plates 3. The lifting drive mechanism includes a lead screw 51 vertically mounted on the outer wall of one of the side plates 3 and a lifting motor 52, with the lifting motor 52 being poweredly connected to the upper end of the lead screw 51. Vertical grooves 30 are vertically formed on the two side plates 3, and limiting blocks 41 fixed to the side ends of the lifting frame 4 are slidably engaged in the corresponding vertical grooves 30. The limiting block 41 near the lead screw 51 is threaded onto the lead screw 51.

[0022] This application significantly improves the stability of the lifting frame 4 when it moves up and down by sliding the limiting block 41 with the vertical grooves 30 on the two side plates 3. By using the lifting motor 52 to drive the lead screw 51 to rotate, the lifting frame 4 can be driven to move up and down through the limiting block 41, thereby adjusting the height of the two traction wheels 6, so that the traction space of the traction wheels 6 corresponds horizontally with the cable management assembly, enabling this device to adapt to the traction operation of cables of different diameters.

[0023] Two traction wheels 6 are vertically arranged side by side on the lifting frame 4. The upper and lower ends of the traction wheels 6 are respectively mounted on upper slider 61 and lower slider 62, which are both horizontally slidably mounted on the lifting frame 4. Specifically, a lower sliding groove 402 is horizontally opened at the bottom of the lifting frame 4, and the two lower sliders 62 are slidably engaged in the lower sliding groove 402; an upper sliding groove 401 is horizontally opened near the top of the lifting frame 4, and the two upper sliders 61 are slidably engaged in the upper sliding groove 401. A traction motor 621 is installed on one of the lower sliders 62, and the traction motor 621 is poweredly connected to the corresponding traction wheel 6; the traction motor 621 drives the traction wheel 6 to rotate, providing power for cable traction.

[0024] This application improves the stability of the two traction wheels 6 when they move horizontally by cooperating with the upper sliding groove 401 and the lower sliding groove 402 with the corresponding upper slider 61 and lower slider 62.

[0025] Two connecting blocks 63 are fixedly mounted above the two upper sliding blocks 61. The two connecting blocks 63 have inclined surfaces on opposite sides, forming an inverted octagonal design. A top block 64 is located between the two connecting blocks 63. The two ends of the top block 64 have inclined edges along the inclination direction of the two inclined surfaces and are slidably connected to the corresponding inclined surfaces. A telescopic cylinder 65 (which can be a hydraulic cylinder structure) is installed on the top of the lifting frame 4. The piston rod of the telescopic cylinder 65 is vertically fixed downwards to the top block 64. A T-slot 630 is formed on the inclined surface of the connecting block 63 along its inclination direction. A T-block 641, which mates with the T-slot 630, is fixed to the end of the top block 64 and slidably engages within the T-slot 630.

[0026] This application utilizes the sliding fit between the T-slot 630 and the T-block 641 to improve the stability of the sliding contact between the top block 64 and the two connecting blocks 63. The telescopic cylinder 65 is used to move the top block 64 up and down. The cooperation between the inclined surfaces of the two connecting blocks 63 and the inclined sides of the top block 64 can move the two connecting blocks 63 away from or closer to each other. Then, the upper slider 61 drives the two traction wheels 6 below to move synchronously, realizing the adjustment of the distance between the two traction wheels 6. This allows the device to be used for traction of cables of different diameters.

[0027] The cable management assembly includes a cable management frame 2 and a rotating ring 21. The cable management frame 2 has a horizontally opening with a circular cable entry port 20. The rotating ring 21 is concentrically mounted on one side of the cable entry port 20. Specifically, an annular guide rail can be concentrically mounted at the cable entry port 20, and the rotating ring 21 is slidably mounted on the guide rail to improve the stability of the rotating ring 21 during rotation. The rotating ring 21 is connected to a rotation drive assembly on the cable management frame 2. Multiple sleeves 22 are rotatably mounted on the rotating ring 21, and the sleeves 22 are set at equal included angles. A movable plate 23 is slidably fitted inside each sleeve 22. One end of the movable plate 23 is rotatably connected to the cable management frame 2, and the other end is movably located at the cable entry port 20. A guide roller 24 of a certain length is mounted on the movable plate 23 along its length near the cable entry port 20, and the guide roller 24 abuts against the outer wall of the cable passing through the cable entry port 20. The rotary drive assembly includes a rotary drive motor 251 and a worm gear 25. The worm gear 25 is mounted on the cable management frame 2 and is powered by the rotary drive motor 251. The outer circumference of the rotating ring 21 is provided with meshing teeth 211, and the worm gear 25 meshes with the meshing teeth 211.

[0028] When the rotary drive motor 251 drives the worm 25 to rotate, the meshing of the worm 25 with the meshing teeth 211 drives the rotating ring 21 to rotate synchronously. The sleeve 22 pushes the movable plate 23 to rotate and swing around the end hinge point, so that the guide roller 24 installed at the movable end of the movable plate 23 can abut against the outer wall of the cable. This allows the device to clamp cables of different diameters and effectively limit and guide the cable during cable traction and pulling. This effectively prevents the cable from swinging back and forth at the traction wheel 6 during the traction action, thus affecting the stability of the traction operation.

[0029] When using this utility model, after passing the cable through the traction port, start the rotary drive motor 251 to make the guide roller 24 on the movable plate 23 clamp the outer wall of the cable. Then drive the lifting motor 52 to adjust the height of the lifting frame 4 and the traction wheel 6, pass the cable through the two traction wheels 6, drive the telescopic cylinder 65 to make the two traction wheels 6 close together to clamp the cable, and start the traction motor 621 to realize the cable traction operation.
