Description

Technical Field

[0001] The present application relates to the technical field of cable laying, and in particular to a cable laying device for a cable trench. Background Art

[0002] Cable trenches are underground pipes used to lay and replace power or telecommunication cable facilities. They are also the enclosure structure for the laid cable facilities. Cable trenches are generally made of concrete or brick, and the top is covered with a cover. To prevent water seepage from corroding the cables, racks are installed on both sides of the cable trench, and the cables are placed in layers on the racks.

[0003] At present, cable laying is mainly done manually. The commonly used laying method is: a cable drum with the cable to be laid is set up at one end of the cable trench, and the end of the cable is clamped and dragged by auxiliary tools to pull the cable out of the drum for laying. In this process, workers need to constantly adjust the position of the cable to place it on the placement rack, which is labor-intensive. Since some placement racks are multi-layer structures, workers are more laborious when making adjustments. In addition, when dragging the cable, the cable skin is easily scratched by the placement rack, which affects the service life of the cable.

[0004] Furthermore, in the process of adjusting the cable position, workers need to enter the cable trench to work. Since there are placement racks on both sides of the cable trench, they are easily scratched by the placement racks while walking, which poses a great safety hazard. Summary of the invention

[0046] See also Figure 1-7 , the cable laying device for the cable trench comprises a frame 1, a moving mechanism 2, a cable drum 4, a first adjusting mechanism 5, a guiding mechanism 6, a second adjusting mechanism 7, and a fixing mechanism 8;

[0047] A moving mechanism 2 is installed at the bottom of the rack 1, and the rack 1 can be moved forward along the cable trench 9 through the moving mechanism 2, so as to facilitate cable laying;

[0048] A cable drum 4 is rotatably mounted on the rack 1. Before use, the length of the cable 41 to be laid is determined first, and then the cable 41 is wound around the cable drum 4, waiting for the laying operation. A first adjustment mechanism 5 for adjusting the longitudinal height position of the cable 41 and a second adjustment mechanism 7 for adjusting the lateral laying position of the cable 41 are installed at the bottom of the rack 1. The laying position of the cable can be adjusted by the first adjustment mechanism 5 and the second adjustment mechanism 7, thereby meeting the requirements of multi-layer cable laying;

[0049] Furthermore, a guide mechanism 6 for supporting and guiding the cable 41 is installed at the bottom of the second adjustment mechanism 7. The guide mechanism 6 can reduce the sliding friction during the cable laying process, ensure the integrity of the cable skin, and thus ensure the service life of the cable. In addition, the length of the guide mechanism 6 can be adjusted according to the size of the cable trench 9.

[0050] Fixing mechanisms 8 corresponding to the side walls of the cable trench 9 are symmetrically installed on both sides of the frame 1. When a long-term cable laying operation is carried out, the laying work cannot be completed in a single operation. When the workers take a break, the position of the frame 1 can be fixed by the fixing mechanism 8 to avoid natural sliding of the device and ensure the safety of the laying operation.

[0051] See also Figure 3 The moving mechanism 2 includes a first motor 21, a moving shaft 24, and a roller 25. The bottom of the frame 1 is rotatably mounted with front and rear moving shafts 24. Both sides of the moving shaft 24 are fixedly connected with rollers 25. The rollers 25 are provided with limit protrusions 26 for limiting the moving direction. When moving normally, the rollers 25 contact the top of the cable trench 9. When the moving direction deviates, the limit protrusions 26 contact the side walls of the cable trench 9, thereby correcting the moving direction, so that the device can move along the direction of the cable trench 9.

[0052] Furthermore, a second gear 23 is fixedly connected to the movable shaft 24, a first motor 21 is fixedly mounted on the frame 1, and a first gear 22 meshing with the second gear 23 is fixedly connected to the output shaft of the first motor 21. The roller 25 can be driven to rotate by the first motor 21, so that the device automatically moves along the cable trench 9.

[0053] Furthermore, since some laying sections are complicated, automatic advancement cannot meet the usage requirements. Therefore, a push handle 11 is provided at the rear of the rack 1, and workers can use the push handle 11 to push the rack 1 to move, thereby meeting the special needs of cable laying.

[0054] See also Figure 4 Two columns 3 are symmetrically arranged on the frame 1, a rotating shaft 31 is rotatably installed between the two columns 3, a cable drum 4 is fixedly connected to the rotating shaft 31, a first sprocket 32 ​​is fixedly connected to the end of the rotating shaft 31, a second motor 33 is installed on the frame 1, a second sprocket 34 is fixedly connected to the output shaft of the second motor 33, the first sprocket 32 ​​and the second sprocket 34 are connected by a chain 35, and the cable drum 4 is driven to retract and release the cable by controlling the forward and reverse rotation of the second motor 33, so as to facilitate the laying operation.

[0055] See also Figure 5The first adjustment mechanism 5 includes a base frame 51, an adjustment frame 53, an outer ring 55, an inner ring 57, and a first guide wheel 58. Two beams 14 are fixed in parallel on the frame 1. One end of the base frame 51 is fixedly connected to the beam 14, and the other end is slidably connected to two adjustment frames 53. An outer ring 55 is fixedly installed between the bottoms of the two adjustment frames 53. The middle of the outer ring 55 is fixedly connected to an inner ring 57 through a first connecting rod 56. The inner ring 57 is a regular hexagon, and six first guide wheels 58 are evenly installed on the inner ring 57. A second positioning hole 52 is provided at the end of the base frame 51, and first adjustment holes 54 are evenly arranged vertically on the adjustment frame 53. The sliding adjustment frame 53 is used to align the first adjustment holes 54 at different positions with the second positioning holes 52 and then fix them through a latch, so as to adjust the height position of the first guide wheel 58. When in use, the cables on the cable reel 4 are passed through the center of the inner ring 57 and the guide mechanism 6 in turn, and then laid on the placement rack 91. The inner ring 57 can be used to limit the cable to prevent the cable 41 from swinging during laying and getting entangled on the placement rack 91, thereby ensuring the smooth progress of the laying operation. The first guide wheel 58 can reduce the sliding friction between the cable laying and the device, thereby ensuring the integrity of the outer skin of the cable 41.

[0056] See also Figure 3 A slide groove 12 is provided on the frame 1, a second adjustment mechanism 7 is installed in the slide groove 12, a guide mechanism 6 is installed at the bottom of the second adjustment mechanism 7, and first positioning holes 13 for fixing the position of the second adjustment mechanism 7 are evenly provided on the frame 1.

[0057] See also Figure 6 The second adjustment mechanism 7 includes a slider 71, a connecting rod 72, a connecting seat 73, a base rod 74, a height adjustment rod 75, and an angle adjustment rod 76. The slider 71 is slidably connected in the slide groove 12. A connecting rod 72 is vertically rotatably installed on the slider 71. The upper end of the connecting rod 72 is fixedly connected to a third gear 721. The lower end of the connecting rod 72 is fixedly installed with a connecting seat 73. Two base rods 74 are symmetrically fixed on the connecting seat 73. A height adjustment rod 75 is slidably connected in the base rod 74. A guide mechanism 6 is installed at the end of the height adjustment rod 75; a third positioning hole 741 is opened on the base rod 74, and second adjustment holes 751 are evenly opened vertically on the height adjustment rod 75. By sliding the height adjustment rod 75, the second adjustment holes 751 at different positions are aligned with the third positioning hole 741, and then fixed by a latch, so that the height position of the guide mechanism 6 is adjusted to meet the multi-layer laying requirements of the cable 41.

[0058] An angle adjustment rod 76 is also rotatably installed on the top of the slider 71, and a fourth gear 761 meshing with the third gear 721 is fixedly connected to the bottom of the angle adjustment rod 76. The connecting rod 72 is rotated by rotating the angle adjustment rod 76, thereby driving the guide mechanism 6 to rotate, and adjusting the orientation angle of the guide mechanism 6 to correspond to the placement rack 91, so as to facilitate cable laying; an adjustment disk 762 is fixedly installed on the top of the angle adjustment rod 76, and the angle adjustment rod 76 can be adjusted more labor-savingly through the adjustment disk 762.

[0059] Furthermore, a limit rod 78 is provided on the slider 71, and two limit rods 78 are provided in parallel. A through hole corresponding to the limit rod 78 is provided on the limit block 79. When the second adjustment mechanism 7 needs to be fixed, the limit block 79 is plugged into the limit rod 78, and the fourth gear 761 is clamped by the limit block 79 to fix it. When the second adjustment mechanism 7 needs to be adjusted, the limit block 79 can be removed. When the limit block 79 is clamped and fixed, the position of the fourth gear 761 needs to be fine-tuned. Since the transmission ratio between the third gear 721 and the fourth gear 761 is relatively large, fine-tuning the fourth gear 761 will not affect the use of the guide mechanism 6.

[0060] See also Figure 6 A plug hole is opened on the slider 71, and first positioning holes 13 corresponding to the plug holes are evenly opened on the frame 1. When in use, the slider 71 is slid to align the plug holes with different first positioning holes 13, and the slider 71 can be fixed by the insertion rod 77, so that the position of the fixed guide mechanism 6 can be adjusted.

[0061] See also Figure 7 The guide mechanism 6 includes a guide frame 61, a pulley 62, a second guide wheel 63, and a second connecting rod 64. The guide frame 61 is a directional structure. The pulleys 62 are rotatably mounted on the upper and lower sides of the guide frame 61, and the second guide wheels 63 are rotatably mounted on the left and right sides.

[0062] Furthermore, adjacent guide frames 61 are connected by a second connecting rod 64 to form a guide channel. When laying, the cable 41 passes through the guide channel. The guide frame 61 can support and limit the cable 41 to prevent the cable 41 from being entangled on the placement rack 91 due to sagging or swinging.

[0063] When laying, the cable 41 passes through the guide mechanism 6 and only bends in the horizontal direction. The pulley 62 is only used to reduce the friction of the cable 41, and there is no need to guide the cable 41. The second guide wheel 63 has both the effects of reducing friction and guiding. Therefore, the diameter of the second guide wheel 63 is required to be larger so that it can support the cable 41 to avoid contact between the cable 41 and the guide frame 61 during guidance, thereby preventing the guide frame 61 from scratching the cable skin.

[0064] See also Figure 3 The fixing mechanism 8 includes a threaded barrel 81, a screw rod 82, and a pressure plate 83. The threaded barrel 81 is symmetrically arranged on the left and right sides of the frame 1. The screw rod 82 is connected in the threaded barrel 81 by threads. A connecting seat 84 is arranged on the side of the pressure plate 83. The end of the screw rod 82 is rotatably connected to the connecting seat 84, so that when the screw rod 82 rotates, the pressure plate 83 will not rotate with it. When it is necessary to suspend the laying operation, the screw rod 82 is rotated to extend it, so that the pressure plates 83 on both sides press against the side walls of the cable trench 9, thereby fixing the frame 1 to prevent the device from sliding naturally.

[0065] On the basis of the above embodiment, since different cable trenches 9 have different sizes, the device can adapt to cable trenches 9 of different widths by replacing movable shafts 24 of different lengths. Furthermore, by increasing or decreasing the number of guide frames 61, the length of the guide mechanism 6 can be changed to adapt to different laying requirements.

[0066] Specific working process:

[0067] Determine the length of the cable 41 to be laid, and control the second motor 33 to drive the cable drum 4 to rotate, so that the cable 41 to be laid is wound on the cable drum 4;

[0068] The device is mounted on the cable trench 9, and the adjusting frame 53 is slid to make the height position of the inner ring 57 correspond to the placement frame 91; the height adjusting rod 75 is slid to make the guide mechanism 6 located at the laying layer, and the direction of the guide mechanism 6 is changed by rotating the adjusting disk 762 so that its port is located above the placement frame 91;

[0069] Pull the end of the cable 41 to pass through the inner ring 57 and the guide mechanism 6 in sequence, and then fix the end of the cable 41 on the placement rack 91 through a clamp to complete the preparation work;

[0070] The first motor 21 is started to drive the device to move forward slowly, and the second motor 33 is started at the same time, so that the cable drum 4 continuously releases the cable 41. It should be noted that the forward speed of the device should be consistent with the release speed of the cable 41, so as to avoid pulling the cable 41 during laying and ensure the integrity of the cable;

[0071] As the device moves forward, the cable 41 passes through the inner ring 57 and the guide mechanism 6, and is placed on the placement rack 91 for automatic laying operations, which reduces the labor intensity of the workers;

[0072] Furthermore, when the operation needs to be suspended, the first motor 21 and the second motor 33 are stopped, and the screws 82 on both sides of the frame 1 are rotated so that the pressing plate 83 presses against the side wall of the cable trench 9, thereby fixing the frame 1 to prevent the frame 1 from sliding naturally.

[0073] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms include, include or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0074] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
