Description

Technical Field

[0001] This invention relates to the field of power construction technology, and in particular to a cable duct laying device. Background Technology

[0002] A cable conduit is a tubular device used to protect cables. Its main function is to protect cables from mechanical damage, chemical corrosion, or other adverse environmental factors. It can effectively prevent cables from being damaged or broken and extend their service life. When installing cables, cable conduits need to be laid first, and cable conduits are often laid in multiple layers. Chinese patent publication number "CN116759950B" discloses a "cable conduit laying device, including a support frame, a laying docking module, and a grinding and gluing module. The support frame has a U-shaped structure, with the laying docking module installed on the right side inside the support frame and the grinding and gluing module installed on the left side inside the support frame." While it can complete the laying of cable conduits, it cannot effectively lay multi-layer cable conduits. When laying multi-layer cable conduits, it is often necessary to manually hoist the cable conduits from a high point to the recessed area, which can easily injure installers at the bottom and poses potential safety hazards. Furthermore, as the number of layers increases, installers need to lift the cable conduits to the installation position, which is time-consuming and labor-intensive, and not conducive to continuous cable conduit installation, resulting in low practicality and functionality. Summary of the Invention

[0006] As a further embodiment of the present invention, the half gear is symmetrically provided with two sets of half teeth on its outer side, and the number of teeth in each set of half teeth is half the number of teeth in the driven gear. The teeth of the half gear are the same in size and height as the teeth of the driven gear.

[0007] As a further embodiment of the present invention, the feeding chamber is arc-shaped, and the feeding chamber is adaptively matched with the movement trajectory of the gripper plate, wherein the gripper plate is U-shaped.

[0008] As a further embodiment of the present invention, one end of the fixed plate is provided with a laying adjustment structure, the laying adjustment structure includes a sliding plate and a plug-in plate, the sliding plate is fixedly installed at one end of the outer side of the fixed plate, a plurality of plug-in plates are sequentially inserted into the front part of the sliding plate near the middle position, a plurality of elastic pads are fixedly installed in the feeding chamber, the inner wall of the sliding plate and the rear part of the plug-in plate, a through groove is opened in the inner side of the sliding plate near the middle position, a sliding seat is slidably installed in the inner side of the through groove, a buffer pad is fixedly installed on the top of the sliding seat, and a plurality of blind holes are opened on both sides of the through groove on the outer side of the sliding plate; The sliding seat has two symmetrical cavities near the rear. A plug rod is inserted into the cavity. A round rod is fixedly installed at the center of one end of the plug rod. An ejector spring is wound around the outside of the round rod. The other end of the plug rod is adapted to the blind hole.

[0009] As a further embodiment of the present invention, one end of the ejector spring is fixedly installed on one end of the insert rod, and the other end of the ejector spring is fixedly installed on the inner wall of the cavity.

[0010] As a further embodiment of the present invention, one end of the insert is provided with a limiting piece, and the limiting piece is adapted to the cavity.

[0011] As a further embodiment of the present invention, the portion of the sliding seat located inside the slide plate is trapezoidal, and there is a gap between the portion of the sliding seat located inside the slide plate and the inner wall of the slide plate.

By using a laying adjustment structure in conjunction with a material conveying structure, the cable pipes delivered by the material conveying structure can be transported to the cable laying depression. Furthermore, the electric telescopic platform can position the cable pipes on the sliding seat at an angle above the laying position, reducing the difficulty of handling the cable pipes and quickly transporting them from the starting point to the cable laying depression, thereby improving laying efficiency and reducing transportation time. Operators only need to pull out the plug plate to quickly place the cable conduit on the cable conduit mounting rack, reducing complicated operation steps and time, improving overall laying efficiency. The close cooperation between the laying adjustment structure, material conveying structure and electric telescopic platform can reduce the workload of operators and reduce direct contact between operators and cable conduits, thus reducing potential safety risks. When laying multiple layers of cable conduits, operators can adjust the combined height of the plug-in plate and the position of the sliding seat to match the height of the cable conduit inside the chute with the height of the laying layer. Operators can make flexible adjustments according to the actual situation, saving time for lifting the cable conduit and enabling faster and more efficient laying of multiple layers of cable conduits. This reduces adjustment and calibration time and further improves work efficiency. The device is simple to operate and easy to use. It can adjust the distance according to the length of different cable pipes, improve the efficiency of laying multi-layer cable pipes, reduce potential threats during cable pipe laying, and enhance the practicality and functionality of the laying device.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-13 As shown, a cable duct laying device includes a counterweight 1, an electric telescopic platform 2 slidably mounted on the top of the counterweight 1, a control handle 3 mounted on the rear of the counterweight 1, and a material conveying structure 4 provided on the top of the electric telescopic platform 2. The material conveying structure 4 includes two upright plates 5, which are symmetrically fixedly installed on the top of the electric telescopic platform 2. A connecting seat 6 is fixedly installed on the top of the electric telescopic platform 2 near the rear. A rotating seat 7 is rotatably installed between the upright plate 5 near the front of the electric telescopic platform 2 and the connecting seat 6 near the top. A horizontal plate 8 is fixedly installed on the outside of the rotating seat 7. A gripper 9 is fixedly installed at one end of the horizontal plate 8. A fixing plate 10 is fixedly installed on the top of the upright plate 5 near the rear of the electric telescopic platform 2, and a square groove is opened inside the fixing plate 10. A half gear 11 is fixedly installed at the rear of the rotating seat 7, and the half gear 11 is located inside the connecting seat 6. A driven gear 12 is rotatably mounted near the top and meshes with a half gear 11. A short connecting rod 13 is fixedly mounted at the rear of the driven gear 12 and is located outside the connecting seat 6. A long connecting rod 14 is rotatably mounted at one end of the short connecting rod 13. A slider 15 is rotatably mounted at one end of the long connecting rod 14 and is located inside the square groove. A feeding seat 16 is fixedly mounted at the rear of the slider 15. A feeding chamber 17 is opened near the bottom of the feeding seat 16. An infeed chamber 18 is opened near the top of the feeding seat 16. A baffle 19 is rotatably mounted at one end of the top of the infeed chamber 18 via a rotating shaft.

[0019] In this embodiment, a drive motor is fixedly installed at the front of the upright plate 5 near the top of the front of the electric telescopic platform 2, and the output shaft of the drive motor passes through the upright plate 5 and is fixedly connected to the rotating seat 7.

[0020] The drive motor can drive the rotating seat 7 to rotate, which in turn can drive the unloading cable pipe to rotate through the gripper 9, and send the cable pipe into the inside of the feeding seat 16, and into the inside of the feeding chamber 17 through the feeding chamber 18. Since the half teeth on the half gear 11 are symmetrically arranged, when the gripper 9 grabs the cable pipe, the half gear 11 and the driven gear 12 are about to disengage. Under the action of the long connecting rod 14 and the short connecting rod 13, the feeding seat 16 is about to be displaced to the initial position. When the gripper 9 grabs the cable pipe and drives the cable pipe to the obliquely upward position, the feeding seat 16 is at the starting position, and the half teeth on the half gear 11 no longer contact the driven gear 12.

[0021] In this embodiment, two sets of half teeth are symmetrically arranged on the outside of the half gear 11, and the number of teeth in each set of half teeth is half the number of teeth in the driven gear 12. The teeth of the half gear 11 and the teeth of the driven gear 12 are the same in size and height.

[0022] As the gripper 9 continues to move, it feeds the cable into the feed chamber 18. The cable then pushes aside the baffle 19 and enters the middle of the feed chamber 18. At this point, the half tooth on the half gear 11 contacts the driven gear 12 again, causing the driven gear 12 to rotate. Since the number of teeth in each set of half teeth is half the number of teeth in the driven gear 12, the half tooth will cause the driven gear 12 to rotate half a turn. Driven by the short connecting rod 13 and the long connecting rod 14, the feed seat 16 moves along the square groove via the slider 15. At this point, the baffle 19 blocks the cable, causing the feed seat 16 to pull the cable away from the gripper 9. This allows the gripper 9 to continue rotating under the drive of the rotating seat 7. When the feed seat 16 moves to the maximum position of the square groove, the cable slides into the feed chamber 17 and moves to the bottom of the feed chamber 17 under the back-and-forth action of the elastic pads 23 on both sides.

[0023] In this embodiment, the feeding chamber 18 is arc-shaped, and the feeding chamber 18 is adaptively matched with the movement trajectory of the gripper 9, which is U-shaped.

[0024] The U-shaped gripper 9 can prevent the cable pipe from coming out of the gripper 9 during movement. The feeding chamber 18 is adaptively matched with the movement trajectory of the gripper 9, which allows the gripper 9 to send the cable pipe into the feeding chamber 18.

[0025] In this embodiment, a laying adjustment structure 20 is provided at one end of the fixed plate 10. The laying adjustment structure 20 includes a sliding plate 21 and a plug-in plate 22. The sliding plate 21 is fixedly installed at one end of the outside of the fixed plate 10. Several plug-in plates 22 are sequentially inserted into the front part of the sliding plate 21 near the middle. Several elastic pads 23 are fixedly installed on the feeding chamber 17, the inner wall of the sliding plate 21, and the rear part of the plug-in plate 22. A through groove 24 is opened in the inside of the sliding plate 21 near the middle. A sliding seat 25 is slidably installed in the inside of the through groove 24. A buffer pad 26 is fixedly installed on the top of the sliding seat 25. Several blind holes 27 are opened on both sides of the through groove 24 on the outside of the sliding plate 21. Two cavities 28 are symmetrically opened inside the sliding seat 25 near the rear. A plug rod 29 is snapped into the cavity 28. A round rod 30 is fixedly installed at the center of one end of the plug rod 29. An ejector spring 31 is wound around the outside of the round rod 30. The other end of the plug rod 29 is adapted to match the blind hole 27.

[0026] After the cable pipe enters the bottom of the feeding chamber 17, it will continue to move slowly to the top of the sliding seat 25 and contact the buffer pad 26 under the action of the elastic pads 23 fixedly installed on both sides of the inner wall of the slide plate 21 and the outside of the plug plate 22. It will then be blocked by the plug plate 22. At this time, the operator can slide the cable pipe onto the cable pipe mounting frame for laying by pulling out the blocking plug plate 22.

[0027] In this embodiment, one end of the ejector spring 31 is fixedly installed on one end of the insert rod 29, and the other end of the ejector spring 31 is fixedly installed on the inner wall of the cavity 28.

[0028] The ejector spring 31 provides elasticity to help the insert rod 29 insert into the blind hole 27, thereby fixing the slide seat 25.

[0029] In this embodiment, a limiting piece is provided at one end of the insert 29, and the limiting piece is adaptively matched with the cavity 28.

[0030] By pulling the round rod 30, the insertion rod 29 can be disengaged from the blind hole 27, thereby adjusting the position of the sliding seat 25 inside the through groove 24. Releasing the handle allows the insertion rod 29 to be inserted into the blind hole 27 under the elastic force of the ejection spring 31. By adjusting the number of plug plates 22, the final position of the cable pipe can be controlled to adapt to the installation height of different layers of cable pipes.

[0031] In this embodiment, the portion of the sliding seat 25 located inside the slide plate 21 is trapezoidal, and there is a gap between the portion of the sliding seat 25 located inside the slide plate 21 and the inner wall of the slide plate 21. A handle is fixedly installed at one end of each of the two round rods 30.

[0032] Since there is a gap between the part of the sliding seat 25 located inside the slide plate 21 and the inner wall of the slide plate 21, the sliding seat 25 can be moved inside the through groove 24 without being blocked by the elastic pad 23. The trapezoidal sliding seat 25 can facilitate the laying of cable pipes in designated positions.

[0033] In this embodiment, several rotating blocks are rotatably installed on both sides of the counterweight 1, and the rotating blocks are fitted with tracks.

[0034] The track allows the device to move on muddy ground, making it easy to adjust its position.

[0035] In this embodiment, the top of the plug-in plate 22 is provided with a protrusion, and the bottom of the plug-in plate 22 and the front of the slide plate 21 near the middle position are provided with grooves. The protrusion and the groove are adapted to each other, and the slide plate 21 is adapted to the feeding cavity 17.

[0036] By using the engagement of protrusions and grooves, the plug-in plates 22 can be combined and connected, making it easy to adjust the combined height of the plug-in plates 22 and lay different layers of cable pipes.

[0037] It should be noted that the present invention is a cable pipe laying device. In use, two of the laying devices are first driven into the concave side of the cable pipe laying area. The distance between the two devices is adjusted according to the required length of the cable pipe to be laid. The position of the gripping plate 9 is adjusted by the electric telescopic platform 2 so that the gripping plate 9 is in the position where the truck unloads the cable pipe. The combined height of the plug plate 22 is adjusted by the cooperation of the protrusion and the groove so that the combined height of the plug plate 22 and the sliding seat 25 are in a suitable position. The cable pipe is unloaded into the gripper plate 9, the drive motor is turned on to drive the rotating seat 7 to rotate, and then the gripper plate 9 drives the cable pipe to rotate. The cable pipe is then fed into the feeding seat 16 and enters the feeding chamber 17 through the feeding chamber 18. The half teeth on the half gear 11 are symmetrically arranged. When the gripper plate 9 grips the cable pipe, the first set of half teeth of the half gear 11 is about to disengage from the driven gear 12, that is, the feeding seat 16 is about to reset. Under the action of the long connecting rod 14 and the short connecting rod 13, the feeding seat 16 is about to move to the starting position of the square groove. When the gripper plate 9 grips the cable pipe and drives the cable pipe to the obliquely upward position, the feeding seat 16 is already at the starting position of the square groove, and the first set of half teeth on the half gear 11 no longer contacts the driven gear 12, so that the feeding seat 16 can remain in the initial position for a period of time, allowing the gripper plate 9 to smoothly feed the cable pipe into the feeding seat 16. Afterwards, the gripper 9 continues to move, sending the cable into the feed chamber 18. The cable then pushes open the baffle 19 and enters the middle position of the feed chamber 18. At this time, the second set of half teeth on the half gear 11 begins to contact the driven gear 12, thereby driving the driven gear 12 to rotate. Since the number of teeth in each set of half teeth is half the number of teeth in the driven gear 12, the half teeth will drive the driven gear 12 to rotate half a turn. With the cooperation of the short connecting rod 13 and the long connecting rod 14, the slider 15 drives the feeding seat 16 to move along the square groove to the farthest distance. At this time, the baffle 19 will block the cable, causing the feeding seat 16 to drive the cable away from the gripper 9. This allows the gripper 9 to continue rotating under the drive of the rotating seat 7 without being blocked by the cable. When the feeding seat 16 moves to the maximum position of the square groove, the cable will slide into the feed chamber 17 and move to the bottom of the feed chamber 17 under the back-and-forth action of the elastic pads 23 on both sides. When the feeder 16 moves to its maximum position, the second set of half teeth will disengage from the driven gear 12, allowing the feeder 16 to maintain its maximum position for a period of time, so that the cable can smoothly enter the interior of the slide plate 21. After the gripper 9 continues to move to the lower half of the device, the first set of half teeth will engage with the driven gear 12, driving the feeder 16 to reset. When the gripper 9 rotates a full circle and returns to the starting position, the feeder 16 will be in the position about to reset, which marks the end of one cable conveying cycle. After the cable pipe enters the bottom of the feeding chamber 17, it will continue to move slowly to the top of the sliding seat 25 and contact the buffer pad 26 under the action of the elastic pads 23 fixed on both sides of the inner wall of the slide plate 21 and the outside of the plug plate 22. It will be blocked by the plug plate 22. The distance of the laying adjustment structure 20 can be adjusted by the electric telescopic platform 2 so that the cable pipe can be at an angle above the laying position. At this time, the operator can slide the cable pipe onto the cable pipe mounting frame for laying by pulling out the blocking plug plate 22. When laying multi-layer cable conduits, the insert rod 29 can be disengaged from the blind hole 27 by pulling the round rod 30, thereby adjusting the position of the sliding seat 25 inside the through groove 24. Releasing the handle allows the insert rod 29 to be inserted into the blind hole 27 under the elastic force of the ejector spring 31. By adjusting the number of plug plates 22, the final position of the cable conduit can be controlled to adapt to the installation height of different layers of cable conduits, and the cable conduit laying work can be completed quickly.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
