Technical Field

[0001] The invention belongs to the technical field of cable installation, and relates to a cable installation structure for electric power construction. Background Art

[0002] During the cable laying process, the cable needs to be pulled along a specific path. When laying the cable, the cable needs to be bent to a certain extent at the bend. The cable is easy to scrape against the corner when passing through the bend, causing damage to the cable insulation layer and even causing the cable to be sprained.

[0003] Therefore, when laying cables, at least one worker needs to be arranged to assist in laying out the cables at the corners, which increases the manpower input. In addition, the corners of the cable trench are usually narrow, making it inconvenient to carry out work there, resulting in low laying efficiency.

[0004] A combined turning guide device for cables with announcement number CN111525452B includes a turning guide assembly, which includes a plurality of detachable turning guide units. By arranging a plurality of detachable turning guide units, the plurality of turning guide units are sequentially connected end to end. By increasing or decreasing the number of turning guide units and adjusting the angle between two adjacent turning guide units, the plurality of turning guide units are connected to form an arc-shaped structure matching the turning radius of the cable, and the cable moves forward with the arc-shaped structure as a guide track. In the actual use of the device, the connection position of the turning guide unit needs to be repeatedly adjusted, which is inefficient and not conducive to improving the efficiency of cable installation.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Figure 1-Figure 8 As shown, the technical solution adopted by the present invention is as follows: a cable installation structure for power construction includes a second support 7 and a guide mechanism arranged on the second support 7. A rotating rod is vertically fixed on the second support 7, and two connecting plates 2 are rotatably installed on the rotating rod. A positioning hole 28 is opened on each connecting plate 2. The connecting plate 2 is limited by screwing the fastening screw into the positioning hole 28, so that the connecting plate 2 is fixed relative to the second support 7. One end of each connecting plate 2 away from the second support 7 is connected to the first support 1. A tensioning mechanism is arranged on the first support 1.

[0021] Specifically, the tensioning mechanism includes a first conveyor belt 4 and a second conveyor belt 26. The second conveyor belt 26 is arranged on the first support 1. A mounting block 3 is detachably mounted on the first support 1, and mounting holes 27 are provided on the first support 1 and the mounting block 3, and the mounting block 3 is fixed to the first support 1 by bolts. The first conveyor belt 4 is mounted on the mounting block 3, and the first conveyor belt 4 and the second conveyor belt 26 on the same side are arranged opposite to each other. The cable 6 passes between the first conveyor belt 4 and the second conveyor belt 26. A plurality of rubber protrusions 5 are fixedly mounted on the first conveyor belt 4 and the second conveyor belt 26, and the first conveyor belt 4 and the second conveyor belt 26 clamp the cable 6 through the rubber protrusions 5.

[0022] The guide mechanism includes a guide roller 9, a fixed cylinder 8 and a rotating cylinder. The fixed cylinder 8 is fixedly mounted on the second support 7. Multiple rotating cylinders are rotatably arranged on both sides of the fixed cylinder 8. Guide rollers 9 are rotatably arranged on the tops of the fixed cylinder 8 and the rotating cylinder. The cable 6 passes around the outside of the guide roller 9, and a groove for accommodating the guide roller 9 is provided on the guide roller 9. The guide roller 9 is used to support the cable 6 and has a guiding function for the cable 6. The fixed cylinder 8 and multiple rotating cylinders are arranged in an arc shape. The radius of the arc is the guide radius of the guide mechanism, and the cable 6 bends along the guide mechanism. The rotating cylinder is rotated while revolving, thereby changing the guide radius, and then making the guide radius adapt to the angle of the turning point.

[0023] The fixed cylinder 8 and the adjacent rotating cylinder are connected via a first connecting rod 29 . One end of the first connecting rod 29 is rotatably arranged relative to the fixed cylinder 8 , and the other end of the first connecting rod 29 is rotatably connected to the corresponding rotating cylinder.

[0024] A first transmission assembly is provided between the fixed cylinder 8 and the adjacent rotating cylinder. The first transmission assembly includes a large gear 12 and a small gear 13. The large gear 12 is coaxially fixed relative to the fixed cylinder 8. Specifically, one of the two large gears 12 is coaxially fixedly connected to the fixed cylinder 8. A first fixed plate 10 is fixedly connected to the second support 7, and the other large gear 12 is fixedly connected to the first fixed plate 10. The small gear 13 is coaxially fixedly connected to the corresponding rotating cylinder. The small gear 13 meshes with the corresponding large gear 12. The pitch circle diameter of the large gear 12 is twice the pitch circle diameter of the small gear 13.

[0025] The first fixed plate 10 is fixedly mounted with a motor 11, and the motor 11 has a self-locking function. The motor shaft of the motor 11 is coaxially fixedly connected with a first bevel gear 22. The second support 7 is fixedly connected with a second fixed plate 24. The second fixed plate 24 is rotatably mounted with a second bevel gear 23 meshing with the first bevel gear 22, and the second bevel gear 23 is meshed with a third bevel gear 25. The fixed cylinder 8 is coaxially fixedly connected with a first rotating shaft, and the third bevel gear 25 is rotatably mounted on the first rotating shaft. The first bevel gear 22 and the third bevel gear 25 are both coaxially arranged with the fixed cylinder 8.

[0026] Among the two first connecting rods 29 , one end of one of the first connecting rods 29 is coaxially fixedly connected to the first bevel gear 22 , and one end of the other first connecting rod 29 is coaxially fixedly connected to the third bevel gear 25 .

[0027] Two adjacent rotating cylinders are connected by a second connecting rod 14. Of the two adjacent rotating cylinders, the rotating cylinder close to the fixed cylinder 8 is fixedly connected to one end of the second connecting rod 14, and the rotating cylinder away from the fixed cylinder 8 is rotatably connected to the other end of the second connecting rod 14. The second connecting rod 14 is located below the corresponding rotating cylinder.

[0028] A second transmission assembly is provided between two adjacent rotating cylinders. Under the action of the second transmission assembly, the two adjacent rotating cylinders rotate synchronously. The second transmission assembly includes a first sprocket 17, a second sprocket 18 and a chain 19. Between two adjacent rotating cylinders, the first sprocket 17 is coaxially fixedly connected to one of the rotating cylinders, the second sprocket 18 is coaxially fixedly connected to the other rotating cylinder, and the chain 19 is transmission-connected between the first sprocket 17 and the second sprocket.

[0029] When the motor 11 is started, the two first connecting rods 29 rotate around the axis of the fixed cylinder 8, and the two first connecting rods 29 rotate in opposite directions, and the multiple rotating cylinders revolve around the axis of the fixed cylinder 8. Under the action of the first transmission assembly, the rotating cylinders adjacent to the fixed cylinder 8 rotate simultaneously.

[0030] It should be noted that there is a certain interval between the fixed cylinder 8 and the rotating cylinder, and between adjacent rotating cylinders.

[0031] Working principle: For the convenience of description, the rotating cylinder adjacent to the fixed cylinder 8 is named as the first rotating cylinder 15, and the rotating cylinder adjacent to the first rotating cylinder 15 is named as the second rotating cylinder 16. The first rotating cylinder 15 is coaxially fixedly connected with the second rotating shaft 21, and the second rotating cylinder 16 is coaxially fixedly connected with the third rotating shaft 20. One end of the second connecting rod 14 between the first rotating cylinder 15 and the second rotating cylinder 16 is fixedly connected to the second rotating shaft 21, and the other end is rotationally connected to the third rotating shaft 20. The pinion 13 is coaxially fixedly connected to the second rotating shaft 21. The first sprocket 17 and the second sprocket 18 corresponding to the second rotating cylinder 16 are both coaxially fixedly connected to the third rotating shaft 20. The distance between the fixed cylinder 8 and the first rotating cylinder 15 and the distance between adjacent rotating cylinders are equal.

[0032] When in use, the angle between the two connecting plates 2 and the guiding radius of the guiding mechanism are adjusted so that the connecting plates 2 and the guiding mechanism cooperate with the turning, so that the cable 6 is bent and deformed at the turning and smoothly transitions at the turning.

[0033] The angle between the two connecting plates 2 is adjusted according to the angle of the turning point, and then the fastening screws are screwed into the positioning holes 28 to fix the connecting plates 2 relative to the second support 7 .

[0034] The guide mechanism is adjusted according to the angle of the turning point. Specifically, the motor 11 is started, the first bevel gear 22 rotates, the third bevel gear 25 rotates, and the first bevel gear 22 and the third bevel gear 25 rotate in opposite directions. The first bevel gear 22 and the third bevel gear 25 both drive the corresponding first connecting rod 29 to rotate, and the two first connecting rods 29 both rotate around the axis of the fixed cylinder 8. The first connecting rod 29 drives the first rotating cylinder 15 to revolve around the axis of the fixed cylinder 8, and the first rotating cylinder 15 drives the second rotating cylinder 16 to revolve around the axis of the fixed cylinder 8 through the second connecting rod 14. Similarly, the multiple rotating cylinders on both sides of the fixed cylinder 8 revolve around the axis of the fixed cylinder 8.

[0035] like Figure 8 As shown, when the guide radius needs to be reduced, the plurality of rotating cylinders are all rotated inwardly around the axis of the fixed cylinder 8.

[0036] When the first rotating cylinder 15 revolves around the axis of the fixed cylinder 8, the first rotating cylinder 15 rotates at the same time due to the meshing of the large gear 12 and the small gear 13. Since the pitch circle diameter of the small gear 13 is half of the pitch circle diameter of the large gear 12, the angular velocity of the first rotating cylinder 15 is twice the angular velocity of its revolution. For example, if the first rotating cylinder 15 revolves around the axis of the fixed cylinder 8 by 3 degrees, the angle of the first rotating cylinder 15 rotation is 6 degrees.

[0037] When the first rotating cylinder 15 rotates, the first rotating cylinder 15 drives the second rotating cylinder 16 to revolve around the axis of the first rotating cylinder 15 through the second connecting rod 14, and the multiple rotating cylinders on the side of the first rotating cylinder 15 away from the fixed cylinder 8 all revolve around the axis of the first rotating cylinder 15. If the angle of the first rotating cylinder 15 rotating is 6 degrees, then the angle of the multiple rotating cylinders on the side of the first rotating cylinder 15 away from the fixed cylinder 8 all revolve around the axis of the first rotating cylinder 15 is 6 degrees.

[0038] When the first rotating drum 15 rotates, under the action of the second transmission assembly, the second rotating drum 16 rotates synchronously with the first rotating drum 15 .

[0039] When the second rotating drum 16 rotates, a plurality of rotating drums on the side of the second rotating drum 16 away from the fixed drum 8 simultaneously revolve around the axis of the second rotating drum 16 and drive the corresponding rotating drums to rotate through the second transmission assembly.

[0040] Therefore, when each rotating drum rotates, it drives a plurality of rotating drums located on the side of the rotating drum away from the fixed drum 8 to revolve, and at the same time drives the corresponding rotating drum to rotate through the second transmission assembly.

[0041] The guide radius is adjusted by rotating the first connecting rod 29 around the axis of the fixing cylinder 8 at a suitable angle, so that the cable 6 can smoothly transition at the bend when the cable 6 is deformed along the guide mechanism.

[0042] Then, the mounting block 3 is disassembled, the cable 6 is mounted on the two second conveyor belts 26 and the cable 6 is bypassed from the guide mechanism, and then the mounting block 3 is fixed to the first support 1, and the first conveyor belt 4 and the second conveyor belt 26 clamp the cable 6. Then, the first conveyor belt 4 and the second conveyor belt 26 are started, so that the first conveyor belt 4 and the second conveyor belt 26 drive the cable 6 to move outward, thereby tightening the cable 6. In the process of tightening the cable 6, the multiple guide rollers 9 have the function of supporting and limiting the cable 6, so that the cable 6 is bent and deformed along the guide mechanism, so that the bending radius of the cable 6 is adapted to the turning point, so that the cable 6 smoothly transitions at the turning point.

[0043] Example 2: Fig. 9As shown, on the projection of the horizontal plane, M is the projection of the rotating rod, N is the axis of the fixed cylinder 8, O is the center of the arc formed by the guide mechanism, P is the axis of the first rotating cylinder 15, and the guide radius is named R. Then, the angle between the two connecting plates 2 is 2×∠QMN. It can be obtained that R: sin∠QMN=MN+R. Since the angle between the two connecting plates 2 is adapted to the turning angle, the value of ∠QMN can be measured. Then the R value can be obtained. In △OPN, R: sin∠ONP=PN: sin∠NOP, and since 2×∠ONP+∠NOP=180°, PN is related to the distance between the axis of the first rotating cylinder 15 and the second rotating cylinder 16, and can be specifically measured. Further, the value of ∠ONP can be obtained. Initially, the fixed cylinder 8 and the plurality of rotating cylinders are on the same straight line, and further, it is obtained that the angle of rotation of the first connecting rod 29 around the axis of the fixed cylinder 8 is: 90°-∠ONP.

[0044] By controlling the rotation angle of the first connecting rod 29 around the axis of the fixing cylinder 8, the guiding radius of the guiding mechanism is adapted to the turning point, thereby facilitating a smooth transition of the cable 6 at the turning point.
