Description

Technical Field

[0001] This invention belongs to the field of cable laying technology, specifically a cable laying device for cable laying projects. Background Technology

[0002] In cable laying projects, commonly used laying devices mainly consist of a carrier plate and a wire roller. The wire roller is fixedly installed on the carrier plate. During operation, the carrier plate is pushed or pulled to move along the preset laying path, which drives the wire roller to rotate synchronously, so that the cable is released from the wire roller and the laying is completed. This structure is widely used in various cable laying scenarios because of its simple structure and low manufacturing cost.

[0003] However, the aforementioned traditional laying devices have many defects in actual use, which seriously affect the laying quality and cable service life. On the one hand, when the carrier plate moves, the rotation of the roller will be subject to resistance generated by bearing friction, its own inertia and braking mechanism. This resistance will be transmitted to the cable, causing the cable to always bear a continuous horizontal traction force. Under this tension, the cable is taut and dragged, causing sliding friction with the ground. Long-term dragging will cause wear, scratches or even damage to the cable outer sheath, which not only increases construction losses, but also reduces the cable insulation performance and leaves safety hazards.

[0004] On the other hand, continuous horizontal tension will stretch the cable during the laying process, resulting in significant residual tensile internal stress and tension after laying. Cables in a taut state are prone to conductor creep, increased resistance, thinning of the insulation layer, accelerated aging, and sheath cracking under stress during long-term use. At the same time, residual tension will reduce the cable's adaptability to environmental changes. When encountering temperature changes, foundation settlement, or slight displacement of the laying path, the cable will be further pulled, which can easily lead to internal wire breakage, joint detachment, and other faults. It is especially unsuitable for laying long-distance, high-voltage, and important lines.

[0005] Therefore, the present invention provides a cable laying device for cable laying projects. Summary of the Invention

[0025] The beneficial effects of this invention are as follows:

[0026] 1. This invention, by incorporating a unidirectional limiting elastic limiting plate, a reciprocating installation cylinder, and a step-by-step laying structure, fundamentally solves the problem of continuous cable traction and dragging friction with the ground in traditional cable laying. During the laying process, the cable is only pulled out in sections and laid naturally, no longer bearing continuous horizontal tension. This effectively avoids wear, scratches, and damage to the outer sheath, improving construction safety and cable integrity. At the same time, this laying method eliminates the residual tensile stress and tension of the cable after laying, keeping the cable in a naturally relaxed state. This avoids problems such as conductor creep, insulation thinning, and accelerated sheath aging, significantly improving the cable's adaptability to temperature changes and foundation settlement, reducing the risk of faults such as wire breakage and joint detachment, and significantly extending the cable's service life. It is especially suitable for long-distance, high-voltage, and important line laying operations.

[0027] 2. This invention integrates stable cable guidance and automatic unlocking by incorporating a flexible clamping guide ring, a synchronously triggered striking shaft, and a mechanical rotating striking structure. During the resetting process of the mounting cylinder, mechanical vibration quickly releases the momentary contact between the limiting plate and the cable, preventing the cable from being accidentally pulled back and ensuring continuous and reliable stepping action. At the same time, the guide structure provides flexible positioning for the cable, effectively avoiding deviation, bending, and jamming during laying. Combined with a precise and controllable reciprocating drive component, the length of each cable laid is uniform and stable, eliminating the need for additional electrical control detection and complex braking systems. The overall structure is simple, stable in operation, and has a low failure rate, significantly improving laying accuracy and construction efficiency. It is suitable for various complex construction environments and has strong practicality and promotional value. Attached Figure Description

[0037] 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.

[0038] like Figures 1 to 7 As shown, the cable laying device for cable laying engineering of the present invention includes a bearing part, a limiting mechanism, a control mechanism and a guiding mechanism.

[0039] The supporting part includes a pallet 1 and a horizontal roller 6. Rollers are provided at the bottom of the pallet 1 to facilitate the movement of the pallet 1. The horizontal roller 6 is rotatably arranged on the upper end face of the pallet 1. The horizontal roller 6 is used to support the winding roller of the cable. Before laying, the horizontal roller 6 is first passed through the winding roller.

[0040] The upper end face of the support plate 1 is fixedly installed with a support column 3 for supporting the horizontal roller 6. A groove for placing the horizontal roller 6 is provided above the support column 3. A cover plate 4 is detachably installed on the upper end face of the support column 3. A groove adapted to the horizontal roller 6 is opened at the bottom of the cover plate 4. By assembling the cover plate 4 with the support column 3, the position of the horizontal roller 6 is fixed, thereby facilitating the rotation of the roller.

[0041] So that the pressure roller 5 for pressing the cable can be flexibly installed on the upper end surface of the pallet 1. After the roller is installed, the outer wall of the pressure roller 5 fits against the cable on the outer ring of the roller, so as to achieve the effect of pressing and prevent the cable from loosening when unwinding.

[0042] The limiting mechanism includes a mounting cylinder 16, a mounting cover 17, and a limiting plate 18. The mounting cylinder 16 is slidably disposed above the support plate 1. The mounting cover 17 is fixedly installed on the outer wall of the mounting cylinder 16. Multiple mounting covers 17 are provided. In this embodiment, three mounting covers 17 are provided. The three mounting covers 17 are evenly distributed in a ring along the axis of the mounting cylinder 16.

[0043] The limiting plate 18 is made of elastic material, and one end is rotatably connected to the inner wall of the mounting cover 17 through an elastic element. The elastic element is a torsion spring. The limiting plate 18 is inclined, and the other end extends into the inner cavity of the mounting cylinder 16. The torsion spring controls the end of the limiting plate 18 to tend to converge toward the middle of the mounting cylinder 16 in real time.

[0044] Before laying, the cable is first passed through the mounting cylinder 16. Under the action of the torsion spring, the ends of the three ring-shaped elastic limiting plates 18 always converge toward the center of the mounting cylinder 16 and contact the outer wall of the cable. When the cable moves toward the roller, it will push the limiting plates 18 to rotate into the mounting cover 17, so that the limiting plates 18 and the cable will generate sliding friction, and the cable can pass through smoothly. When the cable moves in the opposite direction, it will drive the limiting plates 18 to rotate toward the center of the mounting cylinder 16. The inclined structure of the limiting plates 18 forms a self-locking mechanism with the cable, clamping the cable and thus achieving one-way locking.

[0045] The control mechanism is used to control the reciprocating sliding of the mounting cylinder 16. The cable passes through the reciprocatingly movable mounting cylinder 16. When the mounting cylinder 16 moves away from the wire roller, the limiting plate 18 inside it locks in one direction and clamps the cable, pulling out a section of the cable on the wire roller. Then, the support plate 1 moves along the laying path and lays the pulled-out cable on the ground. When the mounting cylinder 16 returns to the direction closer to the wire roller, the limiting plate 18 releases its clamp, and the mounting cylinder 16 can slide smoothly. This process is repeated to achieve step-by-step laying.

[0046] The reciprocating movement of the installation cylinder 16 enables a step-by-step process of pulling the cable first and then laying it. This avoids dragging and friction between the cable and the ground during the laying process, effectively protecting the cable sheath from damage. At the same time, it eliminates the residual internal stress and tension caused by traditional traction laying, allowing the cable to be laid in a naturally relaxed state, improving the cable's service life and operational stability. Furthermore, the amount of cable laid is controllable, effectively preventing cable slack accumulation or excessive tension, making the laying process smoother and the construction quality higher.

[0047] The support mechanism includes a mounting ring 21 and a clamping plate 23. The clamping plate 23 is elastically disposed on one side of the mounting ring 21. The mounting ring 21 is fixedly disposed above the support plate 1, and its axis coincides with the axis of the mounting cylinder 16. The cable first passes through the mounting ring 21 and is clamped by the clamping plate 23. Multiple clamping plates 23 are evenly arranged in a ring along the axis of the mounting ring 21.

[0048] The mounting ring 21 and the elastic clamping plate 23 are coaxially mounted on the support plate 1 to guide and flexibly clamp and position the cable. When the mounting cylinder 16 moves towards the wire roller, it can keep the cable in a stable and straight guiding posture, avoiding cable deviation, bending or jamming, thereby ensuring that the cable can pass through the mounting cylinder 16 smoothly and stably, and ensuring continuous and reliable step-laying process.

[0049] A mounting plate 10 is fixedly installed on the side wall of the support column 3. A horizontal plate 2 is elastically installed on the inner wall of the mounting plate 10. The mounting plate 10 provides support for the horizontal plate 2. The outer wall of the mounting ring 21 is fixedly connected to the outer wall of the horizontal plate 2. The horizontal plate 2 provides support for the mounting ring 21.

[0050] A mounting bracket 22 is fixedly installed on the outer wall of the horizontal plate 2. A connecting plate 24 is rotatably installed on the outer wall of the mounting bracket 22 via a torsion spring. The other end of the connecting plate 24 is fixedly connected to the outer wall of the clamping plate 23, thereby locking the passing wire in one direction. This prevents the cable from sliding on the mounting ring 21 when the mounting cylinder 16 moves toward the cable, further maintaining the stability of the cable laying.

[0051] In a preferred embodiment of the present invention, the control mechanism includes a slide rail 11, a slider 20, a connecting rod 15, a support block 19, a drive motor 8, and a transmission screw 12, wherein the drive motor 8 is preferably a servo motor to facilitate adjustment of the rotation direction of the output shaft.

[0052] The slide rail 11 is fixedly installed on the side wall of the support column 3, and the slider 20 is slidably installed on the inner wall of the slide rail 11. The outer wall of the slider 20 is fixedly connected to the outer wall of the connecting rod 15. The slider 20 is slidably adjusted to drive the connecting rod 15 to slide synchronously.

[0053] The upper end face of the connecting rod 15 is fixedly connected to the bottom surface of the support block 19, and the outer wall of the mounting cylinder 16 is fixedly connected to the upper end face of the support block 19. When the slider 20 slides, the connecting rod 15 drives the support block 19 and the mounting cylinder 16 to slide synchronously.

[0054] The drive motor 8 is fixedly installed on the outer wall of the slide rail 11, and the transmission screw 12 is rotatably installed on the inner wall of the slide rail 11. The drive motor 8 controls the rotation of the transmission screw 12. The output shaft of the drive motor 8 is connected to the axial end of the transmission screw 12 through a belt and a pulley, thereby realizing the control of the rotation of the transmission screw 12 by the drive motor 8.

[0055] The transmission screw 12 passes through the slider 20 and is connected to the slider 20 through internal and external thread engagement. Rotating the transmission screw 12 causes the slider 20 to slide, thereby controlling the reciprocating sliding of the mounting cylinder 16.

[0056] A support bar 14 is fixedly installed on the upper end face of the slide rail 11, and a support cylinder 25 is fixedly installed on the outer wall of the support bar 14, so that the support bar 14 provides support for the support cylinder 25.

[0057] The axis of the support cylinder 25 coincides with the axis of the mounting cylinder 16. As the mounting cylinder 16 moves away from the wire roller, it gradually moves into the inner cavity of the support cylinder 25. The bottom surface of the mounting cylinder 16 is provided with a notch for the support block 19 to pass through, so that the mounting cylinder 16 can enter the inner cavity of the support cylinder 25.

[0058] The outer wall of the support cylinder 25 is elastically fitted with a striking shaft 26 for striking the mounting cover 17. After the mounting cylinder 16 enters the inner cavity of the support cylinder 25, the mounting cylinder 16 begins to move toward the wire roller. At this time, the striking shaft 26 is controlled to strike the outer wall of the mounting cover 17. When the mounting cylinder 16 moves toward the wire roller, if the limiting plate 18 and the cable are not separated in time due to excessive clamping, the vibration of the mounting cover 17 causes the mounting cylinder 16 and the limiting plate 18 to vibrate. The vibration can eliminate the instantaneous contact friction between the limiting plate 18 and the cable, allowing the limiting plate 18 and the cable to quickly disengage and avoid slippage. This ensures that the mounting cylinder 16 is smoothly reset and the cable is not driven back, thereby ensuring the stability and reliability of the step-laying operation.

[0059] In a preferred embodiment of the present invention, a platform 28 is fixedly installed on the outer wall of the support cylinder 25, and an mounting plate 34 is rotatably installed on the side wall of the platform 28 via a torsion spring. The platform 28 provides support for the mounting plate 34, and after the mounting plate 34 is rotated, the elastic force of the torsion spring controls the mounting plate 34 to return to its original position.

[0060] A drive pin 27 is fixedly installed on the outer wall of the striking shaft 26, and a control post 33 for actuating the drive pin 27 is fixedly installed on the axial end of the mounting plate 34. Multiple control posts 33 are evenly arranged along the axis of the mounting plate 34.

[0061] Rotating the mounting plate 34 drives the control column 33 to rotate, which in turn lifts the transmission pin 27 until the control column 33 and the transmission pin 27 separate. At this point, the striking shaft 26 is reset by spring force, thereby achieving the striking of the mounting cover 17.

[0062] A connecting strip 7 is fixedly installed on the outer wall of the support strip 14, and a rotating arm 32 is rotatably installed on the other end of the connecting strip 7. The connecting strip 7 provides installation and support for the rotating arm 32.

[0063] A driven roller 35 is rotatably mounted on the side wall of the mounting plate 34. A connecting rope 29 is fixedly mounted on the outer wall of the driven roller 35. An active roller 30 is rotatably mounted on the outer wall of the rotating arm 32. The other end of the connecting rope 29 is fixedly connected to the outer wall of the active roller 30. Rotating the rotating arm 32 causes the active roller 30 to deflect. At this time, the driven roller 35 is rotated through the connecting rope 29, thereby controlling the rotation of the mounting plate 34. When the rotating arm 32 is reset, the driven roller 35 is controlled by the spring force of the torsion spring to reset synchronously with the mounting plate 34. At this time, the driven roller 35 winds up the connecting rope 29.

[0064] A guide plate 31 is fixedly installed on the outer wall of the support bar 14. A slide rod 13 is elastically installed on the inner wall of the guide plate 31. A spring is provided on the outer wall of the slide rod 13. The other end of the spring is fixedly connected to the outer wall of the guide plate 31. After sliding and adjusting the slide rod 13, the spring force controls the slide rod 13 to return to its original position.

[0065] One end of the slide rod 13 passes through the guide plate 31 and is fixedly installed with a U-shaped frame 9. When the slide rod 13 slides, it drives the U-shaped frame 9 to slide synchronously.

[0066] The side wall of the rotating arm 32 is provided with a waist-shaped groove, and the outer wall of the U-shaped frame 9 is fixedly installed with a pin for sliding cooperation with the waist-shaped groove. By sliding the U-shaped frame 9, the rotating arm 32 is driven to slide, thereby assisting the rotating arm 32 to reset.

[0067] When the mounting cylinder 16 slides into the inner cavity of the support cylinder 25, the mounting cylinder 16 gradually presses against one end of the rotating arm 32, causing the rotating arm 32 to deflect and drive the active roller 30 to rotate. The driven roller 35 and the mounting plate 34 are pulled to rotate through the connecting rope 29. The control column 33 on the mounting plate 34 moves the transmission pin 27 on the striking shaft 26 to achieve the striking of the mounting cover 17.

[0068] Subsequently, the mounting cylinder 16 begins to move towards the wire roller, no longer pressing against the rotating arm 32. The slide rod 13 pushes the U-shaped frame 9 to reset under the action of the spring, driving the rotating arm 32 back to its original position. The mounting plate 34 rotates rapidly under the action of the torsion spring, and the striking shaft 26 strikes the mounting cover 17 again under the action of the elastic force, causing the mounting cylinder 16 and the limiting plate 18 to vibrate, ensuring that the limiting plate 18 is reliably separated from the cable, and realizing automatic and synchronous mechanical striking unlocking.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
