Description

Technical Field

[0001] This invention relates to the field of power distribution network equipment technology, and more specifically, to a power distribution network planning device based on a power distribution network frame. Background Technology

[0002] The power distribution network cable laying planning device is a complete set of planning and construction auxiliary devices for intelligent route optimization of overhead cable route selection.

[0003] Chinese Patent Publication No. CN214590482U discloses a power distribution network planning device based on a power distribution network frame, including a fixed plate. A support device is fixedly connected to the top of the fixed plate, and a mounting frame is fixedly connected to the bottom of the fixed plate. A connecting frame is fixedly connected to the bottom of the mounting frame, and a fixing device is fixedly connected to the end of the connecting frame away from the mounting frame.

[0004] The aforementioned power distribution network planning device achieves the goal of setting up a fixed device, facilitating the clamping and fixing of the entire unit to the utility pole, placing the entire unit on the utility pole, and using the support device to support the wires, making it convenient for workers to erect the lines. At the same time, the support device can be adjusted to compress and fix the wires, improving the stability of the wire fixation. It is convenient for workers to select according to construction needs, improving work efficiency and meeting usage requirements. Traditional power distribution network cable erection planning and conveying equipment often uses two sets of oppositely arranged guide rollers to pull and convey the cable. Since the size and specifications of the guide rollers are fixed, when conveying small-diameter cables, the cables are prone to shaking and deviation within the gap between the two sets of guide rollers. Long-term reciprocating conveying will aggravate the wear on the cable surface and easily scratch the cable insulation surface, posing a significant safety hazard. In addition, the existing equipment guide roller conveying distance and anti-sway limiting structure are adjusted independently and step by step, and cannot be adjusted synchronously according to the actual diameter of the cable. The overall adjustment process is cumbersome and complex, which greatly reduces the efficiency of power distribution network cable erection and conveying operations. Summary of the Invention

An anti-sway plate is fixedly mounted on one end surface of each of the two connecting plates. A conveying cable is arranged on the surface of the two limiting shafts. After the two anti-sway plates move towards each other, they prevent the cable from swaying during conveying. An arc pressure plate is fixedly mounted on the top surface of each sliding rod.

[0008] Preferably, the surface of the rotating cylinder has multiple through holes that match the slide rod, the inner sides of the two fixed disks are fixedly mounted with rotating bases, and the two end surfaces of the rotating cylinder are fixedly mounted with rotating rings. The rotating rings are matched and rotatably connected with the rotating bases, and the rotating cylinder is rotatably connected with the fixed disks through the matching of the rotating rings and rotating bases.

[0009] Preferably, the two ends of the rotating drum are symmetrically provided with through grooves, and a matching slide plate is slidably connected inside each groove. The slide plate is fixedly connected to the movable rod. The two ends of the rotating drum are provided with circular grooves, and the two fixed plates are provided with through holes. The movable rod extends through the circular grooves and through the through holes to one side of the fixed plate.

[0010] Preferably, mounting brackets are fixedly installed on the surfaces of both fixed disks, through-type connecting rods are slidably connected to the surfaces of both mounting brackets, toothed plates are fixedly connected to one end of the surfaces of both connecting rods, and rotating seats are fixedly installed on the other end of the surfaces of both connecting rods. One end of the movable rod is rotatably connected to the rotating seat.

[0011] Preferably, two fixed seats are symmetrically arranged above the base. The interior of each fixed seat is rotatably connected to a gear that meshes with a toothed plate. The interior of each fixed seat is slidably connected to a toothed plate that meshes with the gear. One end of each toothed plate is fixedly connected to two connecting plates.

[0012] Preferably, two upright plates are symmetrically fixedly installed on the surface of the base, and the top surfaces of the two upright plates are respectively fixedly connected to two fixed seats. Two vertical plates are symmetrically fixedly installed on the surface of the base, and the two vertical plates are respectively fixedly connected to two fixed plates.

[0013] Preferably, each of the two connecting rods is fitted with a spring for resetting its movement. One end of the spring is fixedly connected to the rotating seat, and the other end of the spring is fixedly connected to the mounting bracket.

[0014] Preferably, an upper frame is fixedly mounted on the surfaces of the two fixed disks, and a lifting frame that can move vertically up and down is provided inside the upper frame. A spinning roller is rotatably connected to the inner side of the lifting frame.

[0015] Preferably, both sides of the upper frame are provided with through vertical slots, and a matching lifting plate is slidably connected inside each of the two vertical slots. One end of each of the two lifting plates is fixedly connected to the lifting frame. A second spring is elastically connected between the lifting plate and the vertical slot. One end of the second spring is fixedly connected to the inner wall of the vertical slot, and the other end of the second spring is fixedly connected to the lifting plate.

[0016] Preferably, the surface of the upper frame is threaded with a through-type threaded rod, and the bottom surface of the threaded rod is rotatably connected to the surface of the lifting frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) When this distribution network planning device based on the distribution network frame is in use, the rotating roller moves the cable to squeeze the arc pressure plate. The movement of the arc pressure plate moves the sliding rod downward, causing the squeezing plate to move downward and squeeze the two inclined seats. This causes the two movable rods to move in opposite directions. The two movable rods move in opposite directions and respectively move the sliding plate inside the slide groove. The two movable rods move in opposite directions and respectively move the two rotating seats. The movement of the rotating seats causes the connecting rod and the toothed plate to move and squeeze the spring. The two toothed plates move in opposite directions and respectively drive the two gears to rotate. This causes the two toothed plates to move towards each other. The two toothed plates move towards each other and cause the two connecting plates and the two anti-sway plates to move towards each other. The two anti-sway plates contact the cable surface. During the cable transportation process, the surfaces of the two limiting shafts limit the cable, and the two anti-sway plates prevent the cable from swaying during transportation. Compared with traditional distribution network planning and transportation equipment, the cable will not shake or deviate between the surfaces of the two limiting shafts, preventing long-term reciprocating transportation from aggravating the wear of the cable surface and avoiding scratches on the cable surface insulation layer.

[0019] 2) When using this power distribution network planning device based on the power distribution network frame, the limit shaft and the two anti-sway plates can be adjusted synchronously. This solves the problem of independent step-by-step adjustment of the guide roller conveying distance and the anti-sway limit structure in the existing equipment. The overall process is convenient and fast, which improves the efficiency of power distribution network construction and transportation operations.

[0020] 3) When this power distribution network planning device based on the power distribution network frame is in use, for cables with larger diameters, after the cable is squeezed by the spinning roller and contacts the surface of the first support platform, the arc pressure plate is squeezed and moves the sliding rod downward with a smaller displacement. This results in a smaller displacement of the two movable rods in opposite directions, and consequently, a smaller displacement of the two connecting plates and the two anti-sway plates towards each other. The two anti-sway plates then contact the surface of the cable with a larger diameter. For cables with smaller diameters, when the cable is squeezed by the spinning roller and contacts the surface of the third support platform, the arc pressure plate is squeezed and moves the sliding rod downward with a larger displacement. This results in a larger displacement of the two movable rods in opposite directions, and consequently, a larger displacement of the two connecting plates and the two anti-sway plates towards each other. The two anti-sway plates then contact the surface of the cable with a smaller diameter. This device is suitable for laying cables of different diameters. Moreover, the displacement between the two anti-sway plates can be adaptively adjusted according to the different diameters of the cables to ensure that the two anti-sway plates contact the cable surface, reducing swaying during cable transportation and increasing the practicality and functionality of the equipment.

[0031] Please see Figure 1 - Figure 9A power distribution network planning device based on a power distribution network frame includes a support frame 1 and multiple bases 2 fixedly mounted on its surface. Two fixed disks 3 are symmetrically arranged above each base 2, and a rotatable drum 4 is arranged between the two fixed disks 3. Two limiting shafts 5 are symmetrically fixedly mounted on the surface of the drum 4. The design of the two limiting shafts 5 allows for the conveying and limiting of cables 15 of different diameters. The surface of the limiting shafts 5 is provided with a first support platform 6, a second support platform 7, and a third support platform 8 that descend sequentially. The first support platform 6, the second support platform 7, and the third support platform 8 support the cables 15 of different diameters, preventing the cables 15 from swaying during conveying. Two movable rods 9 are symmetrically slidably connected inside the drum 4. Multiple inclined seats 10 are fixedly installed on one end surface of each of the rotating drums 4. Multiple sliding rods 11 are slidably connected to the surface of each of the rotating drums 4. The sliding rods 11 are used to guide the movement of the extrusion plate 12. An extrusion plate 12 for extruding the inclined seat 10 is fixedly installed on the bottom surface of any sliding rod 11. A connecting plate 13 that follows the movement of the movable rod 9 is provided on one side of each of the two fixed discs 3. The connecting plate 13 moves in the opposite direction to the movable rod 9. An anti-sway plate 14 is fixedly installed on one end surface of each of the two connecting plates 13. The anti-sway plate 14 prevents the cable 15 from swinging during the conveying process. The conveying cable 15 is provided on the surface of the two limiting shafts 5. The cable 15 is a conventional cable 15 in the prior art. After the two anti-sway plates 14 move towards each other, they prevent the cable 15 from swinging during the conveying process. Arc pressure plates 16 are fixedly installed on the top surface of the slide rod 11. The rotating roller 36, carrying the cable 15, moves to squeeze the arc pressure plates 16. The movement of the arc pressure plates 16 causes the slide rod 11 to move downward, causing the extrusion plate 12 to move downward and simultaneously squeeze the two inclined seats 10. This causes the two movable rods 9 to move in opposite directions. The two movable rods 9, moving in opposite directions, respectively cause the slide plate 21 to slide inside the slide groove 20. The two movable rods 9, moving in opposite directions, cause the two rotating seats 32 to move. The movement of the rotating seats 32 causes the connecting rod 24 and the toothed plate 25 to move and squeeze the spring 33. The two toothed plates 25, moving in opposite directions, respectively cause the two gears 27 to rotate, which in turn causes the two toothed plates 28 to move towards each other. The two toothed plates 28, moving towards each other, cause the two connecting plates 13 and the two Two anti-sway plates 14 move towards each other and contact the surface of the cable 15. During the cable 15 transport process, the surfaces of the two limiting shafts 5 limit the cable 15, and the two anti-sway plates 14 prevent the cable 15 from swaying during transport. Compared with traditional power distribution network construction and planning equipment, the cable 15 will not sway or deviate between the surfaces of the two limiting shafts 5, which prevents long-term reciprocating transport from aggravating the wear of the cable 15 surface and avoids scratches on the insulation layer of the cable 15 surface. At the same time, the limiting shafts 5 and the two anti-sway plates 14 can be adjusted synchronously, which solves the problem of independent step-by-step adjustment of the guide roller conveying distance and the anti-sway limiting structure in existing equipment. The overall process is convenient and fast, which improves the efficiency of power distribution network construction and transport operations.For cables 15 with larger diameters, when the cable 15 is pressed by the spinning roller 36 and contacts the surface of the first support platform 6, the arc pressure plate 16 experiences a smaller downward displacement due to the compression motion, which in turn causes the sliding rod 11 to move downwards. This results in a smaller displacement of the two movable rods 9 in opposite directions, and consequently, a smaller displacement of the two connecting plates 13 and the two anti-sway plates 14 in opposite directions. The two anti-sway plates 14 then contact the surface of the cable 15 with the larger diameter. For cables 15 with smaller diameters, when the cable 15 is pressed by the spinning roller 36 and contacts the surface of the third support platform 8, the arc pressure plate 16 experiences a smaller downward displacement due to the compression motion. The downward displacement of the sliding rod 11 is relatively large, resulting in a large displacement of the two movable rods 9 in opposite directions. This, in turn, causes a large displacement of the two connecting plates 13 and the two anti-sway plates 14 towards each other. The two anti-sway plates 14 contact the surface of the cable 15 with a smaller diameter, making it suitable for laying cables 15 of different diameters. Furthermore, the displacement between the two anti-sway plates 14 can be adaptively adjusted according to the different diameters of the cables 15, ensuring that the two anti-sway plates 14 contact the surface of the cable 15, reducing the swaying of the cable 15 during transport, and increasing the practicality and functionality of the equipment.

[0032] Please see Figure 7 - Figure 9 The surface of the rotating drum 4 has multiple through holes 17 that match the slide rod 11. The inner sides of the two fixed plates 3 are fixedly installed with rotating bases 18. The two ends of the rotating drum 4 are fixedly installed with rotating rings 19. The rotating rings 19 and rotating bases 18 are matched and rotatably connected. The rotating drum 4 is rotatably connected to the fixed plate 3 through the matching of rotating rings 19 and rotating bases 18. The design of rotating rings 19 and rotating bases 18 ensures the stable rotation of the rotating drum 4.

[0033] Please see Figure 6 - Figure 9 The two ends of the rotating cylinder 4 are symmetrically provided with through grooves 20. Each groove 20 is slidably connected to a matching slide plate 21. The matching design of the slide plate 21 and the groove 20 ensures the stable sliding of the movable rod 9. The slide plate 21 is fixedly connected to the movable rod 9. Both ends of the rotating cylinder 4 are provided with circular grooves 22. Both fixed plates 3 are provided with through holes 31. The movable rod 9 extends through the circular grooves 22 and the through holes 31 to one side of the fixed plate 3.

[0034] Please see Figure 6 - Figure 9Both fixed plates 3 are fixedly mounted with mounting brackets 23, and both mounting brackets 23 are slidably connected with through-type connecting rods 24. One end of each connecting rod 24 is fixedly connected with a toothed plate 25, and the other end of each connecting rod 24 is fixedly mounted with a rotating seat 32. One end of the movable rod 9 is rotatably connected to the rotating seat 32. The rotating seat 32 and one end of the movable rod 9 are rotatably connected, which not only completes the pressing of the movable rod 9 on the rotating seat 32, but also completes the rotation of the movable rod 9 inside the rotating seat 32.

[0035] Please see Figure 1 - Figure 7 Two fixed seats 26 are symmetrically arranged above the base 2. The inside of each fixed seat 26 is rotatably connected to a gear 27 that meshes with a toothed plate 25. The inside of each fixed seat 26 is slidably connected to a toothed plate 28 that meshes with a gear 27. One end of each toothed plate 28 is fixedly connected to two connecting plates 13.

[0036] Please see Figure 1 - Figure 5 Two upright plates 29 are symmetrically fixedly installed on the surface of the base 2. The top surfaces of the two upright plates 29 are respectively fixedly connected to two fixed seats 26. Two vertical plates 30 are symmetrically fixedly installed on the surface of the base 2. The two vertical plates 30 are respectively fixedly connected to two fixed plates 3.

[0037] Please see Figure 7 Both connecting rods 24 are fitted with springs 33 for resetting their movement. Springs 33 are used to reset the movement of connecting rods 24. One end of spring 33 is fixedly connected to rotating seat 32, and the other end of spring 33 is fixedly connected to mounting bracket 23.

[0038] Please see Figure 1 -4. The surfaces of the two fixed plates 3 are jointly fixedly mounted with an upper frame 34. The upper frame 34 is equipped with a lifting frame 35 that can move vertically up and down. The inner side of the lifting frame 35 is rotatably connected to a spinning roller 36.

[0039] Both sides of the upper frame 34 are provided with through vertical slots 37. The interior of each vertical slot 37 is slidably connected with a matching lifting plate 38. One end of each lifting plate 38 is fixedly connected to the lifting frame 35. A second spring 39 is elastically connected between the lifting plate 38 and the vertical slot 37. One end of the second spring 39 is fixedly connected to the inner wall of the vertical slot 37, and the other end of the second spring 39 is fixedly connected to the lifting plate 38. The design of the second spring 39 makes the lifting frame 35 more smooth and stable during the lifting process.

[0040] The upper frame 34 has a threaded connection to a through threaded rod 40, and the bottom surface of the threaded rod 40 is rotatably connected to the surface of the lifting frame 35.

[0041] The usage steps of this invention are as follows: When using this power distribution network planning device based on a power distribution network frame, during the overhead transmission and installation of cable 15, firstly, one end of cable 15 is passed between the two limiting shafts 5 and the spinning roller 36. Then, the threaded rod 40 is rotated, and the threaded rod 40 rotates downward, causing the lifting frame 35 to move downward. The downward movement of the lifting frame 35 causes the two lifting plates 38 to move downward inside the vertical groove 37, compressing the second spring 39. The downward movement of the lifting frame 35 also causes the spinning roller 36 to move downward. After the spinning roller 36 moves downward and contacts the surface of cable 15, as the spinning roller 36 continues to move downward, the spinning roller 36 moves with cable 15 to squeeze the arc pressure plate 16. The movement of the arc pressure plate 16 causes the sliding rod 11 to move downward, causing the squeezing plate 12 to move downward and squeeze the two The inclined seat 10 causes the two movable rods 9 to move in opposite directions. These opposite movements cause the slide plate 21 to slide inside the slide groove 20. The opposite movements of the two movable rods 9 also cause the two rotating seats 32 to move. The rotating seats 32 then cause the connecting rod 24 and the toothed plate 25 to move, compressing the spring 33. The opposite movements of the two toothed plates 25 then cause the two gears 27 to rotate, resulting in the two toothed plates 28 moving towards each other. The two toothed plates 28 moving towards each other cause the two connecting plates 13 and the two anti-sway plates 14 to move towards each other. The two anti-sway plates 14 contact the surface of the cable 15. For cables 15 with larger diameters, when the cable 15 is compressed by the spinning roller 36 and contacts the surface of the first support platform 6, the arc pressure plate 16 is compressed. The downward displacement of the sliding rod 11 is relatively small, resulting in a small displacement of the two movable rods 9 in opposite directions. Consequently, the opposing displacement of the two connecting plates 13 and the two anti-sway plates 14 is also relatively small. The two anti-sway plates 14 contact the surface of the cable 15 with a larger diameter. For the cable 15 with a smaller diameter, when the cable 15 is squeezed by the spinning roller 36 and contacts the surface of the third support platform 8, the arc pressure plate 16 is squeezed. The downward displacement of the sliding rod 11 is relatively large, resulting in a large displacement of the two movable rods 9 in opposite directions. Consequently, the opposing displacement of the two connecting plates 13 and the two anti-sway plates 14 is also relatively large. The two anti-sway plates 14 contact the surface of the cable 15 with a smaller diameter. After the two anti-sway plates 14 contact the surface of the cable 15... At this time, pulling the end of the cable 15 causes the spinning roller 36 and the two limiting shafts 5 to rotate. The rotation of the two limiting shafts 5 causes the rotating drum 4 to rotate, and the rotation of the rotating drum 4 causes the rotating ring 19 to rotate within the rotating seat 18. The rotation of the rotating drum 4 also causes the sliding rod 11 and the sliding plate 21 to rotate (multiple sliding rods 11 rotate, causing multiple arc pressure plates 16 to rotate. Multiple arc pressure plates 16 are provided. During the cable 15 conveying process, the cable 15 squeezes one arc pressure plate 16 and does not detach. As the rotating drum 4 rotates, another arc pressure plate 16 rotates and is already squeezed by the surface of the cable 15. When the cable 15 squeezes one arc pressure plate 16 and detaches, the other arc pressure plate 16 has already been squeezed by the surface of the cable 15, preventing the squeezing from being interrupted during the rotation of multiple arc pressure plates 16).This causes the two movable rods 9 to rotate with the rotating drum 4. At this time, the ends of the movable rods 9 rotate inside the rotating seat 32, ensuring the smooth transport of the cable 15. This scheme uses the spinning roller 36 to move the cable 15 and squeeze the arc pressure plate 16. The movement of the arc pressure plate 16 causes the sliding rod 11 to move downward, causing the pressing plate 12 to move downward and squeeze the two inclined seats 10. This causes the two movable rods 9 to move in opposite directions. The two movable rods 9 moving in opposite directions respectively cause the sliding plate 21 to slide inside the slide groove 20. The two movable rods 9 moving in opposite directions also cause the two rotating seats 32 to move. The movement of the rotating seats 32 causes the connecting rod 24 and the toothed plate 25 to move and squeeze the spring 33. The two toothed plates 25 move in opposite directions. The motion drives the two gears 27 to rotate, which in turn causes the two toothed plates 28 to move towards each other. This movement of the two toothed plates 28, in turn, causes the two connecting plates 13 and two anti-sway plates 14 to move towards each other. The two anti-sway plates 14 contact the surface of the cable 15. During the cable 15 transport process, the surfaces of the two limiting shafts 5 limit the cable 15, and the two anti-sway plates 14 prevent the cable 15 from swaying during transport. Compared to traditional partial distribution network installation and transport equipment, the cable 15 will not experience swaying or deviation between the surfaces of the two limiting shafts 5, preventing long-term reciprocating transport from accelerating wear on the cable 15 surface and avoiding scratches on the insulation layer of the cable 15. Simultaneously, it can effectively protect the limiting shafts 5 and the two anti-sway plates 14. The synchronous adjustment of the swing plate 14 solves the problem of independent step-by-step adjustment of the guide roller conveying distance and the anti-sway limiting structure in existing equipment. The overall process is convenient and fast, improving the efficiency of power distribution network construction and transmission operations. For cables 15 with larger diameters, when the cable 15 is squeezed by the spinning roller 36 and contacts the surface of the first support platform 6, the arc pressure plate 16 is squeezed and moves the sliding rod 11 downward with a small displacement. This results in a small displacement of the two movable rods 9 in opposite directions, which in turn results in a small displacement of the two connecting plates 13 and the two anti-sway plates 14 in opposite directions. The two anti-sway plates 14 contact the surface of the cable 15 with a larger diameter. For cables 15 with smaller diameters, when the cable 1... When the 5th element is pressed against the surface of the third support platform 8 by the spinning roller 36, the arc pressure plate 16 moves downwards with the sliding rod 11 due to the pressure, resulting in a large displacement. This causes the two movable rods 9 to move in opposite directions with a large displacement, which in turn causes the two connecting plates 13 and the two anti-sway plates 14 to move towards each other with a large displacement. The two anti-sway plates 14 contact the surface of the cable 15 with a smaller diameter, making it suitable for laying cables 15 of different diameters. Moreover, the displacement between the two anti-sway plates 14 can be adaptively adjusted according to the different diameters of the cables 15, ensuring that the two anti-sway plates 14 contact the surface of the cable 15, reducing the swaying of the cable 15 during transportation, and increasing the practicality and functionality of the equipment.
