Description

Technical Field

[0001] The present invention relates to cable laying technology, in particular to a power cable installation, traction and laying device. Background Art

[0002] In the construction of power projects, cable traction and laying is a key process. The quality of cable laying directly affects the stable operation of the power system and the service life of the cables. High-quality cable laying can ensure the efficiency and stability of power transmission, reduce power outages caused by cable failures, and ensure the normal operation of residents' lives and industrial production. Existing cable traction and laying devices are generally suitable for laying straight paths. In these devices, the cables can maintain a preset distance from the side walls of the groove during the laying process to reduce wear and ensure the accuracy of the laying. However, in actual power cable laying scenarios, the groove path is often not completely straight, but there are corner sections with various angles, especially corners of 30°-150° are more common.

[0003] When existing cable traction and laying equipment encounters such corner sections, the cable's inertia during traction causes radial deviation, causing the cable to cling to the groove sidewalls. This clinging phenomenon persists during subsequent traction and laying. Once the power cable is in operation, the friction between the cable and the groove sidewalls increases with natural environmental changes and possible external interference, leading to cable wear. Summary of the Invention

[0004] The purpose of the present invention is to provide a power cable installation traction and laying device to solve the problem in the prior art that when the cable traction and laying device encounters a corner section, the cable is radially offset toward the groove side wall due to traction inertia, and is easily worn by friction with the side wall during subsequent laying and use.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a power cable installation, traction and laying device, comprising a mobile trolley, a wire roller and a wire pay-off drive mechanism, wherein a through hole for the cable to pass through is provided on the body of the mobile trolley, the wire roller is rotatably mounted on the mobile trolley, one end of the wire roller is connected to the wire pay-off drive mechanism for driving the wire roller to rotate around its own axis, and further comprising:

[0010] The compensation mechanism is installed between the two guide mechanisms. The compensation mechanism includes a swing frame, a push rod, a sliding frame and two B guide wheels. The sliding frame is provided with an A slide groove. One side of the swing frame is fixedly connected to the bottom end of the rotating shaft. The push rod can rotate around the axis of the rotating shaft with the swing frame. The outer wall of the push rod is slidably connected to the A slide groove. The sliding frame is slidably installed on the bottom of the mounting plate, and the two B guide wheels are rotatably installed on the sliding frame.

[0011] Furthermore, the guide mechanism also includes a fixed frame, a rotating drive member A, an A slider and an A telescopic drive member. One side of the fixed frame is fixedly connected to the mounting plate, the output shaft end of the A rotating drive member passes through the fixed frame and is fixedly connected to the end of one of the A guide wheels, one end of the other A guide wheel is rotatably connected to the A slider, the A slider is slidably installed on the fixed frame, one side of the A slider is fixedly connected to the moving end of the A telescopic drive member, and the fixed end of the A telescopic drive member is fixedly connected to the fixed frame.

[0012] Furthermore, the adjusting component includes a screw A, a rotation drive assembly and two B sliders. The two B sliders correspond one-to-one to the two limiting wheels. One end of the two limiting wheels is rotatably connected to the corresponding B sliders. Two thread grooves with opposite rotation directions are provided on the screw A. The screw A is threadedly connected to the two B sliders through the two thread grooves thereon. One side of the two B sliders is slidably connected to the adjustment plate respectively. The outer side of the screw A is connected to the rotation drive assembly for driving the screw A to rotate around its own axis.

[0013] Furthermore, the rotary drive assembly includes a worm wheel and a worm, the worm wheel is fixedly sleeved on the outside of screw A, one side of the worm wheel is engaged with the worm, and the upper end outer wall of the worm is rotatably connected to the adjustment plate.

[0014] Furthermore, one end of the push rod away from the A slide groove is fixedly connected to the swing frame.

[0015] Furthermore, a C slider is fixedly connected to the end of the push rod away from the A slide groove, a B slide groove is provided on the swing frame, and the C slider is slidably installed in the B slide groove. One side of the C slider is connected to a moving drive component for driving the C slider to move along the length direction of the B slide groove.

[0018] Compared with the prior art, the power cable installation, traction and laying device provided by the present invention, when encountering a corner section, the limiting wheel causes the adjustment plate to rotate around the axis of the rotating shaft, thereby driving the swing frame to rotate, the push rod pushes the inner wall of the sliding frame to drive the sliding frame to move, and the sliding frame drives the two B guide wheels to move laterally, forming a dynamic guide track, so that the cable is away from the side wall inside the groove corner section, thereby significantly reducing the friction between the cable and the groove side wall, effectively avoiding the wear of the cable caused by friction, and extending the service life of the cable;

[0019] By setting an adjustment component, the two limiting wheels are driven to move and move away from each other until they respectively abut against the side walls of the groove for laying cables. The adjustment can be flexibly adjusted according to the width of the groove for laying different cables, ensuring that the limiting wheels always maintain good contact with the side walls of the groove, providing a basis for subsequent guiding and anti-wear functions.

[0020] The A telescopic drive member drives the A slider to slide, adjusting the distance between the two A guide rollers. The A rotary drive member rotates the A guide roller, creating a traction-assisted force that facilitates smooth cable laying. Simultaneously, as the B guide roller pushes against the cable, the A rotary drive member in the guide mechanism, away from the trolley, controls the A guide roller to rotate. Clamped between the two A guide rollers, the cable is guided in a direction opposite to the trolley's movement, preventing the cable from being pulled toward the inner wall of the groove due to the lateral pushing force of the B guide roller, further ensuring the quality of cable laying.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figures 1 to 6 A power cable installation, traction and laying device includes a mobile trolley 100, a wire roller 200 and a wire-paying drive mechanism 210. The body of the mobile trolley 100 is provided with a through hole 110 for the cable to pass through. The wire roller 200 is rotatably mounted on the mobile trolley 100. One end of the wire roller 200 is connected to the wire-paying drive mechanism 210 for driving the wire roller 200 to rotate around its own axis. The wire-paying drive mechanism 210 is a B rotary drive member. The output shaft end of the B rotary drive member is connected to one end of the wire roller 200 through a transmission belt. The output shaft end of the B rotary drive member and the end of the wire roller 200 are both fixedly sleeved with a transmission wheel. The two transmission wheels are sleeved with the same transmission belt. The device also includes:

[0032] A mounting plate 120 is provided at the end of the mobile trolley 100, with one side of the mounting plate 120 fixedly connected to the body of the mobile trolley 100;

[0033] The adjustment plate 300 is disposed on a side of the mounting plate 120 away from the moving vehicle 100. One end of the adjustment plate 300 is fixedly connected to a rotating shaft 310. The lower outer wall of the rotating shaft 310 is rotatably connected to the mounting plate 120.

[0034] The limiting mechanism 400 is mounted on the adjustment plate 300 and includes an adjustment component 410 and two limiting wheels 420. One end of each limiting wheel 420 is connected to the adjustment component 410. The adjustment component 410 is used to drive the two limiting wheels 420 to move away from each other until they abut against the side walls of the groove where the cable is laid.

[0035] Two guide mechanisms 500 are respectively mounted on the bottom of the mounting plate 120 , and the guide mechanisms 500 include two A guide wheels 510 ;

[0036] The compensation mechanism 600 is installed between the two guide mechanisms 500. The compensation mechanism 600 includes a swing frame 610, a push rod 620, a sliding frame 630 and two B guide wheels 640. The sliding frame 630 is provided with an A slide groove 650. One side of the swing frame 610 is fixedly connected to the bottom end of the rotating shaft 310. The push rod 620 can rotate around the axis of the rotating shaft 310 with the swing frame 610. The outer wall of the push rod 620 is slidingly connected to the A slide groove 650. The sliding frame 630 is slidably installed at the bottom of the mounting plate 120, and the two B guide wheels 640 are rotatably installed on the sliding frame 630.

[0037] Existing cable pulling and laying devices can only maintain a preset distance between the cable and the groove sidewall in a straight path. When encountering a 30°-150° angle section, the cable will produce radial deviation due to pulling inertia, and the cable will easily stick to the groove sidewall. This will cause friction between the cable and the groove sidewall during subsequent pulling and laying and later use, causing cable wear.

[0038] To this end, the present application sets a mobile trolley 100 as a carrying platform, and the cable passes through the through hole 110, between the two A guide wheels 510 on the side close to the mobile trolley 100, between the two B guide wheels 640, and between the two A guide wheels 510 in another guide mechanism 500 in sequence. The wire roller 200 realizes active wire pay-off through the wire pay-off drive mechanism 210;

[0039] Before laying the cable, the two limiting wheels 420 are driven by the adjusting component 410 to move and move away from each other until they respectively abut against the side walls of the groove for laying the cable, so that the limiting wheels 420 can adapt to the width of different cable laying grooves. When the mobile trolley 100 moves, if it encounters a corner section, under the action of the limiting wheels 420, the adjusting plate 300 rotates around the axis of the rotating shaft 310, and the adjusting plate 300 drives the rotating shaft 310 to rotate. When the rotating shaft 310 rotates, it drives the swing frame 610 to rotate, and the push rod 620 rotates with the swing frame 610. The push rod 620 pushes the inner wall of the A slide 650 to drive the sliding frame 630 to move, and the sliding frame 630 drives the two B guide wheels 640 to move horizontally, forming a dynamic guide track. In the corner section of the groove, the cable is kept away from the side wall on the inner side of the groove corner section, thereby effectively reducing the friction between the cable and the groove side wall, which causes cable wear.

[0040] In one embodiment of the present invention, the guide mechanism 500 further includes a fixed frame 520, a rotary drive member A 530, a slider A 540, and a telescopic drive member A 550. The telescopic drive member A 550 is a pneumatic cylinder or a hydraulic cylinder. One side of the fixed frame 520 is fixedly connected to the mounting plate 120. The rotary drive member A 530 is a servo motor. The output shaft end of the rotary drive member A 530 passes through the fixed frame 520 and is fixedly connected to the end of one of the guide wheels A 510. One end of the other guide wheel A 510 is rotatably connected to the slider A 540. The slider A 540 is slidably mounted on the fixed frame 520. One side of the slider A 540 is fixedly connected to the movable end of the telescopic drive member A 550. The fixed end of the telescopic drive member A 550 is fixedly connected to the fixed frame 520.

[0041] Specifically, the A telescopic driving member 550 drives the A slider 540 to slide, thereby adjusting the distance between the two A guide wheels 510, and the A rotary driving member 530 drives the A guide wheel 510 to rotate, thereby generating a traction auxiliary force.

[0042] During the traction and laying process, the lateral pushing force of the B guide wheel 640 can easily pull the laid cables, causing the cables to stick to the inner wall of the groove. Therefore, when the B guide wheel 640 pushes the cables, the A rotating drive member 530 in the guide mechanism 500 away from the moving trolley 100 is controlled to drive the A guide wheel 510 to rotate. Under the clamping of the two A guide wheels 510, the cables are guided to move in the direction opposite to the moving direction of the moving trolley 100, avoiding the lateral pushing force of the cable B guide wheel 640 pulling the cables in the opposite direction.

[0043] In one embodiment of the present invention, the adjustment component 410 includes an A screw 411, a rotation drive assembly, and two B sliders 412. The two B sliders 412 correspond one-to-one to the two limiting wheels 420. One end of the two limiting wheels 420 is rotatably connected to the corresponding B sliders 412. The A screw 411 is provided with two sections of thread grooves with opposite rotation directions. The A screw 411 is threadedly connected to the two B sliders 412 through the two sections of thread grooves thereon. One side of the two B sliders 412 is respectively slidably connected to the adjustment plate 300. The outer side of the A screw 411 is connected to the rotation drive assembly for driving the A screw 411 to rotate around its own axis.

[0044] Specifically, two sections of thread grooves with opposite rotation directions (left-hand thread and right-hand thread) are machined on the A screw 411. When the rotary drive assembly drives the A screw 411 to rotate around its own axis, the two sections of thread rotation directions are opposite, and the two B sliders 412 make opposite linear motions along the screw axis under the action of thread meshing (one moves to the left and the other moves to the right). The B slider 412 is slidably connected to the adjustment plate 300 through a slide rail or guide groove to ensure the linear accuracy of the movement trajectory and avoid deflection and jamming, thereby realizing the opposite movement of the two limiting wheels 420 to adapt to grooves of different widths.

[0045] In one embodiment of the present invention, the rotary drive assembly includes a worm gear 413 and a worm 414. The worm gear 413 is fixedly sleeved on the outside of the screw A 411. One side of the worm gear 413 is meshed with the worm 414. The upper outer wall of the worm 414 is rotatably connected to the adjustment plate 300.

[0046] Specifically, the worm gear 413 is driven to rotate by rotating the worm 414. The operator rotates the worm 414 (manually or electrically) so that its spiral tooth surface makes continuous point contact with the meshing teeth of the worm gear 413, converting the rotational motion of the worm 414 into the rotational power of the worm gear 413. The worm gear 413 drives the A screw 411 to rotate, thereby realizing the position adjustment of the two limiting wheels 420.

[0047] In one embodiment of the present invention, one end of the push rod 620 away from the A slide groove 650 is fixedly connected to the swing frame 610 .

[0048] In one embodiment of the present invention, a C slider 660 is fixedly connected to the end of the push rod 620 away from the A chute 650. A B chute 670 is defined on the swing frame 610. The C slider 660 is slidably mounted in the B chute 670. One side of the C slider 660 is connected to a movement drive assembly for driving the C slider 660 to move along the length direction of the B chute 670.

[0049] In one embodiment of the present invention, the mobile drive assembly includes a C rotary drive member 680 and a B screw 690. The outer wall of the B screw 690 is threadedly connected to the C slider 660. The outer walls of the two ends of the B screw 690 are respectively rotatably connected to the swing frame 610. One end of the B screw 690 is fixedly connected to the output shaft end of the C rotary drive member 680. The C rotary drive member 680 is fixedly mounted on the swing frame 610. The C rotary drive member 680 adopts a servo motor or a cylinder.

[0050] Specifically, the C rotary drive member 680 drives the B screw 690 to rotate, and through the threaded engagement with the C slider 660, pushes the C slider 660 to move linearly along the B slide groove 670, thereby adjusting the position of the push rod 620, that is, adjusting the distance between the push rod 620 and the rotating shaft 310, so that the moving distance of the sliding frame 630 can be adjusted to adapt to the different curvature radii of the groove corners, which is more in line with actual paving conditions.

[0051] In one embodiment of the present invention, the outside of the limiting wheel 420 is covered with a wear-resistant layer (not shown in the figure), and the wear-resistant layer can be made of polyurethane elastomer (PU) to reduce the wear of the main component (limiting wheel 420) and extend the service life of the equipment.

[0052] In one embodiment of the present invention, an angle sensor is further provided. The angle sensor is mounted on the mounting plate 120 and is used to measure the rotation angle of the rotating shaft 310. The angle section during cable laying is obtained through the measurement data of the angle sensor.

[0053] The angle sensor (such as a rotary encoder or a potentiometer) monitors the rotation angle of the rotating shaft 310 in real time through non-contact or contact measurement. When the adjustment plate 300 rotates around the rotating shaft 310 along the curved path of the groove, the sensor converts the mechanical angle into an electrical signal; the sensor signal is transmitted to the control system (such as a PLC or an embedded controller). According to the detected rotation angle, the control system synchronously adjusts the stroke of the push rod 620 of the compensation mechanism 600, the direction speed of the line roller 200 driven by the wire-releasing drive mechanism 210, and the guide wheel speed of the guide mechanism 500 to form a closed-loop control.

[0054] In one embodiment of the present invention, a corresponding control unit can be provided for use in conjunction with the present invention. The control unit can be connected to the electrical components of the present application using any controller, thereby controlling the opening and closing operations of the electrical components. This part is prior art, and a single-chip microcomputer can be provided as a control unit for demonstration. The single-chip microcomputer in this embodiment is a typical embedded microcontroller (Microcontroller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware required) and cost savings. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0055] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
