Description

Technical Field

[0001] This invention belongs to the field of auxiliary installation tools for live-line work, and specifically relates to an insulated umbrella rapid pole climbing installation device. Background Technology

[0002] In the field of live-line operation and maintenance of power distribution networks, the proximity of the work area to surrounding live conductors and phase-to-phase conductors during live-line work on overhead distribution lines poses a significant risk of electric shock and phase-to-phase short circuits, seriously threatening the personal safety of workers. To meet the safety protection requirements for live-line work, the industry commonly uses insulating umbrellas (also known as insulating partitions) as dedicated safety isolation and protection components. In live-line work scenarios, insulating umbrellas are temporarily installed and fixed below the crossarms of the towers, forming a reliable insulating barrier that effectively separates the work area from live parts, blocks phase-to-phase and phase-to-ground discharge channels, and prevents accidental contact with live conductors, induced electric shock, and phase-to-phase short circuits during work. They provide safe insulation protection for high-altitude live-line work and are an indispensable core safety protection tool in live-line maintenance, defect elimination, and renovation of power distribution networks.

[0003] Currently, the mainstream construction method for installing insulating umbrellas during live-line work on distribution networks relies entirely on manual pole climbing by workers. The existing conventional procedure is as follows: workers, carrying insulating umbrellas, installation accessories, and safety equipment, climb to the installation position below the crossarm of the tower using traditional pole climbing tools such as foot straps and safety belts. In this high-altitude, near-electric, and fully energized environment, they manually align and install the insulating umbrellas. After maintenance is completed, they manually climb the pole to remove the umbrellas. While this traditional manual pole climbing method can temporarily install and isolate insulating umbrellas, it has many inherent technical shortcomings in actual live-line work applications and is difficult to adapt to the current requirements for safe, efficient, and standardized operation management in live-line work on distribution networks.

[0004] First, manual pole climbing for installation is labor-intensive and inefficient, severely slowing down the overall live-line work progress. The insulating umbrellas have a certain volume, area, and weight, requiring workers to wear full sets of heavy live-line protective gear while climbing to the high-altitude crossarm work area. The working space below the crossarm is confined, restricting working posture, making the manual alignment, erection, and securing of the insulating umbrellas cumbersome and time-consuming.

[0005] Secondly, high-altitude manual installation of live electrical equipment carries extremely high safety risks and is very difficult to manage. The entire process of installing insulated umbrellas takes place in a near-electric, high-risk environment. Workers are suspended on poles and positioned at great heights, facing multiple safety hazards including falls, electric shocks from high voltage, and arc burns. Adverse weather conditions such as strong winds, rain, snow, and fog further reduce the safe working window and decrease the stability of high-altitude operations, greatly increasing the risk of accidents. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rapid pole climbing and installation device for insulated umbrellas, so as to solve the problems of high labor intensity, low work efficiency, and multiple safety risks such as high-altitude falls and high-voltage electric shock in the existing manual pole climbing and installation of insulated umbrellas.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An insulated umbrella rapid pole climbing and installation device includes a pole climbing robot and a clamping device disposed on the upper part of the pole climbing robot. The pole climbing robot includes a first climbing frame and a second climbing frame. One end of the first climbing frame and the second climbing frame are connected by a hinge, and the other end is connected by a fastening mechanism. The first climbing frame and the second climbing frame are each provided with a mounting base. At least two sets of walking mechanisms are rotatably connected to both sides of the mounting base in a vertical direction. Each set of walking mechanisms includes walking wheels symmetrically arranged on both sides of the mounting base. A drive mechanism for driving the walking mechanism to move along the pole is provided on one side of the second climbing frame.

[0008] The clamping device includes a mounting box and a V-shaped clamping block. Connecting frames are fixedly connected to both sides of the mounting box, and plugs are provided at the ends of the connecting frames. A partition is provided inside the mounting box, and a telescopic mechanism is provided on one side of the partition. The end of the telescopic mechanism is connected to the V-shaped clamping plate, and a power supply is provided on the other side of the partition. The V-shaped clamping block has slots on both sides that are compatible with the plugs. Electromagnets are provided at the bottom of both the V-shaped clamping block and the mounting box. The upper part of the first crawling frame and the second crawling frame is provided with pads that cooperate with the electromagnets. The top of the V-shaped clamping block and the mounting box is provided with connection holes for fixing the insulating umbrella.

[0009] Furthermore, the traveling mechanism also includes a first coupling disposed at one end of the traveling wheel and a second coupling disposed at the other end of the traveling wheel. Both the first coupling and the second coupling are universal couplings of the cross shaft type. The first coupling is rotatably mounted on the mounting base. Short shafts are rotatably connected to the side walls at both ends of the first and second crawling frames, and the short shafts are connected to the second coupling. The traveling wheels on both sides of the mounting base are arranged at an angle, and the rim of each traveling wheel abuts against the outer cylindrical surface of the pole. The pressing direction of the traveling wheel on the pole is arranged radially along the pole. The short shaft at one end of the second crawling frame extends to the outside of the second crawling frame and is connected to a pulley. Adjacent pulleys are connected by a transmission belt. The driving mechanism includes a motor base disposed on one side of any traveling wheel and a drive motor mounted on the motor base. The output shaft of the drive motor is connected to the axle of the traveling wheel.

[0010] Furthermore, the first coupling has spline grooves at both ends, and the axle on one side of the traveling wheel is slidably fitted into the spline groove; the mounting base has a threaded hole in the middle, and adjusting screws are rotatably connected to the side walls of the first and second crawling frames, with the adjusting screws threaded into the threaded holes of the mounting base; guide rods are symmetrically fixed on the upper and lower sides of the mounting base, and the first and second crawling frames have through holes that fit with the guide rods with clearance, one end of the guide rod passes through the through hole and is connected to a fixed end plate, and an anti-loosening spring is sleeved on the outside of the guide rod, with one end of the anti-loosening spring abutting against the fixed end plate and the other end abutting against the outer wall of the first or second crawling frame.

[0011] Furthermore, both the first and second crawling frames are fixedly connected to ear plates on the side away from the hinge. The fastening mechanism includes a connecting shaft with limiting end plates at both ends to prevent the bushings from slipping off the ends of the connecting shaft. Two sets of spacer rings are symmetrically arranged in the middle of the connecting shaft. A bushing is slidably connected to each side of the connecting shaft. A tension spring is provided between the bushing and the corresponding spacer ring. Connecting rods are symmetrically hinged to both sides of the bushing. The ends of the two connecting rods on the same side of the connecting shaft are hinged to a hanging plate. An insert rod is fixedly connected to the lower part of the hanging plate. The lower end of the insert rod is inserted into the ear plate and threaded with an anti-loosening nut.

[0012] Furthermore, the spacer ring is threadedly connected to the connecting shaft and is used to adjust the initial preload of the tension spring.

[0013] Furthermore, both the first and second crawling frames are provided with buffer legs at their lower parts. Each buffer leg includes a fixed leg fixedly installed at the bottom of the first or second crawling frame and a sleeve that is gapped around the fixed leg. A fixed baffle is fixedly connected to the middle of the fixed leg. A buffer spring is fitted around the outside of the sleeve. The lower end of the buffer spring is connected to the bottom of the sleeve, and the upper end of the buffer spring is connected to the fixed baffle.

[0014] Furthermore, a counterweight rod is fixedly connected to one side of the V-shaped clamping block, and several detachable counterweight rings are threaded onto the counterweight rod.

[0015] Furthermore, the slot has an open top and a closed bottom structure. The slot as a whole has a right-angled trapezoidal structure with a wider top and a narrower bottom. The side wall of the slot near the V-shaped clamping plate has a right-angled waist. The shape of the plug is adapted to the slot.

[0016] Furthermore, the telescopic mechanism adopts a threaded self-locking electric push rod.

[0017] Furthermore, the V-shaped clamping plate has several through slots in the middle, and several eccentric wheels are rotatably connected inside the through slots. The rotation center of the eccentric wheels is set close to the V-shaped clamping block. After the pole is clamped, the minimum radial position of the eccentric wheel abuts against the outer wall of the pole.

[0018] The beneficial effects of this invention are: (1) This invention utilizes a pole-climbing robot in conjunction with a clamping device to replace the traditional manual pole-climbing operation mode of wearing protective equipment and carrying an umbrella. It eliminates the tedious process of manually aligning, setting up, fastening, and disassembling the insulating umbrella at high altitudes, reduces the labor intensity of the operation, improves the efficiency of disassembling and assembling the insulating umbrella, and ensures the safety of workers working near electricity at high altitudes.

[0019] (2) This solution sets a first coupling and a second coupling on both sides of the traveling wheel, and both the first coupling and the second coupling are universal couplings of cross shaft. The position of the mounting seat is adjusted with the adjusting screw so that the traveling wheel is perpendicular to the outer circle of the pole. Compared with the parallel arrangement of the traveling wheels, the effective contact area between the traveling wheel and the pole is increased, ensuring the fit and friction between the traveling wheel and the pole, while avoiding uneven wear of the traveling wheel.

[0020] (3) The fastening mechanism adopts a self-tensioning structure. It uses the elastic pushing effect of the tension spring to keep the fastening mechanism in a tensioned state. It can adaptively extend and retract according to the size difference of the outer diameter of the pole to ensure the pre-tightening force between the walking wheel and the pole, thereby avoiding the situation of loosening and slipping during the climbing process of the pole climbing robot and ensuring the stability of the pole climbing operation.

[0021] (4) By setting buffer legs, when the pole climbing robot slips, loosens, or fails to clamp, it will fall unexpectedly. The sleeve will contact the ground or support surface first. The buffer spring will generate compression deformation between the fixed baffle and the bottom of the sleeve, converting the rigid impact energy generated by the fall into the elastic potential energy of the spring, thereby achieving buffering and unloading, offsetting the impact load of the fall, and avoiding damage to the pole climbing robot.

[0022] (5) A counterweight rod is set on one side of the V-shaped clamping block, and multiple counterweight rings are threaded onto the counterweight rod. During the process of the robot carrying the insulating umbrella climbing, the overall center of gravity of the device is balanced by increasing or decreasing the number of counterweight rings or adjusting the position of the counterweight rings, so as to ensure that the whole machine has a correct climbing posture and balanced force, and avoid tilting or swaying during the climbing process. When the device climbs to the position, the clamping device holds the pole and completes the fixing of the insulating umbrella, the position of the counterweight rings on the counterweight rod is changed to make the clamping device generate an eccentric load, forming a self-locking effect, which ensures the reliability of the clamping device.

[0036] The following will be combined with the appendix Figures 1-12The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0038] like Figure 1 , Figure 2 As shown, an insulating umbrella rapid pole-climbing installation device includes a pole-climbing robot 2 and a clamping device 4 disposed on the upper part of the pole-climbing robot 2, such as... Figure 4 As shown, the pole-climbing robot 2 includes a first climbing frame 21 and a second climbing frame 22. One end of the first climbing frame 21 and the second climbing frame 22 are connected by a hinge, and the other end is connected by a fastening mechanism 24, as shown. Figure 5 As shown, both the first climbing frame 21 and the second climbing frame 22 are provided with mounting bases 25. At least two sets of walking mechanisms are rotatably connected to both sides of the mounting base 25 in the vertical direction. Each set of walking mechanisms includes walking wheels 26 symmetrically arranged on both sides of the mounting base 25. The second climbing frame 22 is provided with a drive mechanism on one side for driving the walking wheels 26 of the walking mechanism to rotate, thereby causing the pole climbing robot 2 to climb or descend along the pole axis.

[0039] like Figures 9 to 11 As shown, the clamping device 4 includes a mounting box 42 and a V-shaped clamping block 41. Connecting frames 43 are fixedly connected to both sides of the mounting box 42. The ends of the connecting frames 43 are provided with plugs 431. The mounting box 42 has a partition 421 inside. A telescopic mechanism 44 is provided on one side of the partition 421. The end of the telescopic mechanism 44 is connected to a V-shaped clamping plate 45. A power supply 46 is provided on the other side of the partition 421. The V-shaped clamping block 41 has slots 411 on both sides that are compatible with the plugs 431. Electromagnets 414 are provided at the bottom of both the V-shaped clamping block 41 and the mounting box 42. The upper parts of the first crawling frame 21 and the second crawling frame 22 are provided with pads 29 that cooperate with the electromagnets 414. The top of the V-shaped clamping block 41 and the mounting box 42 are provided with connecting holes for fixing the insulating umbrella 1.

[0040] During installation of the insulating umbrella 1, the hinged first climbing frame 21 and second climbing frame 22 are first opened and fitted onto the outside of the pole. The pole-climbing robot 2 is then secured by the fastening mechanism 24. Next, the clamping device 4 is magnetically attached to the top of the pole-climbing robot 2 via the electromagnet 414 at the bottom and the pad 29 at the top. The split insulating umbrella 1 is then fixed to the top of the clamping device 4 through the connecting hole. The drive motor 28 is started, and the belt drive structure drives the walking wheels 26 to rotate synchronously, propelling the pole-climbing robot 2 to carry the clamping device 4 and the insulating umbrella 1 along the pole. The pole automatically climbs to the designated position; once in position, the telescopic mechanism 44 drives the V-shaped clamping plate 45 to extend, cooperating with the V-shaped clamping block 41 to clamp the pole and achieve high-altitude fixation of the clamping device 4. Subsequently, the electromagnet 414 is de-energized to release the magnetic attraction, and the pole-climbing robot 2 automatically falls back to the ground, completing the unmanned high-altitude deployment of the insulating umbrella 1. When the insulating umbrella 1 is dismantled, the pole-climbing robot 2 automatically climbs again to connect with the high-altitude clamping device 4. The electromagnet 414 is energized to attract and fix it, and the telescopic mechanism 44 retracts to release the pole clamping state, allowing the clamping device 4 and the insulating umbrella 1 to fall back to the ground as a whole, completing the dismantling operation.

[0041] like Figure 3 , Figure 5 As shown, the walking mechanism further includes a first coupling 261 disposed at one end of the walking wheel 26 and a second coupling 262 disposed at the other end of the walking wheel 26. Both the first coupling 261 and the second coupling 262 are universal couplings of the cross shaft type. The first coupling 261 is rotatably mounted on the mounting base 25. Short shafts 263 are rotatably connected to the side walls at both ends of the first crawler frame 21 and the second crawler frame 22, and the short shafts 263 are connected to the second coupling 262. The walking wheels on both sides of the mounting base 25 The 26 wheels are arranged at an angle, with the rim of each wheel abutting against the outer cylindrical surface of the pole, and the pressing direction of the wheels 26 against the pole is arranged radially along the pole; the short shaft 263 at one end of the second climbing frame 22 extends to the outside of the second climbing frame 22 and is connected to a pulley 264, and adjacent pulleys 264 are connected by a transmission belt; the driving mechanism includes a motor base 27 disposed on one side of any of the wheels 26 and a drive motor 28 mounted on the motor base 27, and the output shaft of the drive motor 28 is connected to the axle of the wheel 26.

[0042] In this scheme, the universal joint of the cross shaft is used to make the traveling wheels 26 on both sides of the mounting base 25 arranged at an angle, so that the traveling wheels 26 are perpendicular to the outer circle of the pole. Compared with the traveling wheels 26 arranged in parallel, the effective contact area between the traveling wheels 26 and the pole is increased, ensuring the fit and friction between the traveling wheels 26 and the pole, while avoiding uneven wear of the traveling wheels 26.

[0043] The first coupling 261 has spline grooves at both ends, and the axle on one side of the traveling wheel 26 is slidably fitted into the spline groove; for example Figure 6 As shown, the mounting base 25 has a threaded hole 251 in the middle. Adjusting screws 252 are rotatably connected to the side walls of the first crawling frame 21 and the second crawling frame 22. The adjusting screws 252 are threadedly engaged with the threaded hole 251 of the mounting base 25. Guide rods 253 are symmetrically fixed on the upper and lower sides of the mounting base 25. The first crawling frame 21 and the second crawling frame 22 are provided with through holes that are clearance-fitted with the guide rods 253. One end of the guide rod 253 passes through the through hole and is connected to a fixed end plate. An anti-loosening spring 254 is sleeved on the outside of the guide rod 253. One end of the anti-loosening spring 254 abuts against the fixed end plate, and the other end abuts against the outer wall of the first crawling frame 21 or the second crawling frame 22.

[0044] This structure utilizes the spline groove at the end of the first coupling 261 to slide with the axle of the traveling wheel 26, allowing the axle to achieve axial sliding compensation within the spline groove, providing displacement margin for the angle adjustment of the traveling wheel 26. By rotating the adjusting screw 252 on the side wall of the climbing frame, the mounting base 25 is driven to move in position, thereby synchronously adjusting the included angle of the traveling wheels 26 on both sides of the mounting base 25. This allows the contact angle and clamping distance of the traveling wheels 26 to be adapted and adjusted according to the diameter of the utility pole, ensuring that utility poles of different thicknesses can achieve multi-point contact and clamping, thus enhancing the adaptability of the device.

[0045] The guide structure of the guide rod 253 improves the stability of the position adjustment of the mounting base 25 and avoids the mounting base 25 from tilting; together with the elastic pre-tightening anti-loosening structure of the anti-loosening spring 254, the loosening problem caused by the thread clearance of the adjusting screw 252 can be eliminated, ensuring the stability of the mounting base 25 after adjustment.

[0046] like Figure 4 As shown, both the first crawler frame 21 and the second crawler frame 22 have ear plates 23 fixedly connected to the side away from the hinge, such as... Figure 8 As shown, the fastening mechanism 24 includes a connecting shaft 241. The connecting shaft 241 has limiting end plates at both ends to prevent the bushings 242 from slipping off from both ends of the connecting shaft 241. Two sets of spacer rings 247 are symmetrically arranged in the middle of the connecting shaft 241. A bushing 242 is slidably connected to each side of the connecting shaft 241. A tension spring 246 is provided between the bushing 242 and the corresponding side spacer ring 247. Connecting rods 243 are symmetrically hinged to both sides of the bushings 242. The ends of the two connecting rods 243 on the same side of the connecting shaft 241 are hinged to a hanging plate 244. A plug rod 245 is fixedly connected to the lower part of the hanging plate 244. The lower end of the plug rod 245 is inserted into the ear plate 23 and threaded with an anti-loosening nut.

[0047] In this scheme, the elastic pushing action of the tension spring 246 is used to keep the fastening mechanism 24 in a tensioned state. It can adaptively extend and retract according to the size difference of the outer diameter of the pole, ensuring the preload between the walking wheel 26 and the pole, thereby avoiding loosening and slippage during the climbing process of the pole climbing robot 2 and ensuring the stability of the pole climbing operation.

[0048] like Figure 8 As shown, the spacer ring 247 is threadedly connected to the connecting shaft 241. By changing the position of the spacer ring 247 on the connecting shaft 241, the distance between the spacer ring 247 and the bushing 242 is changed, thereby compressing or releasing the tension spring 246, thus adjusting the initial preload of the tension spring 246. Furthermore, by reducing the preload of the tension spring 246, i.e., by bringing the two spacer rings 247 closer together and moving the inserts 245 at both ends further apart, the assembly of the fastening mechanism is facilitated. After assembly, the spacer rings 247 can be adjusted to the appropriate position according to the required preload.

[0049] like Figure 4 , Figure 7 As shown, both the first crawling frame 21 and the second crawling frame 22 are provided with buffer legs 3 at their lower parts. The buffer legs 3 include a fixed leg 31 fixedly installed at the bottom of the first crawling frame 21 or the second crawling frame 22 and a sleeve 33 that is gapped outside the fixed leg 31. A fixed baffle 32 is fixedly connected to the middle of the fixed leg 31. A buffer spring 34 is sleeved outside the sleeve 33. The lower end of the buffer spring 34 is connected to the bottom of the sleeve 33, and the upper end of the buffer spring 34 is connected to the fixed baffle 32.

[0050] Under normal operating conditions, the sleeve 33 and the buffer spring 34 are in a normal assembly state, which does not affect the robot's normal climbing and fitting operations. When the pole climbing robot 2 experiences slippage, loosening, or clamping failure and falls unexpectedly, the sleeve 33 will first contact the ground or support surface. The buffer spring 34 will generate compression deformation between the fixed baffle 32 and the bottom of the sleeve 33, converting the rigid impact energy generated by the fall into the elastic potential energy of the spring, thereby achieving buffering and unloading, offsetting the impact load of the fall, and preventing damage to the pole climbing robot 2.

[0051] like Figure 9 , Figure 10 As shown, a counterweight rod 412 is fixedly connected to one side of the V-shaped clamping block 41, and several detachable counterweight rings 413 are threaded onto the counterweight rod 412.

[0052] During the robot's ascent carrying the insulating umbrella 1, the overall center of gravity of the device is precisely balanced by increasing or decreasing the number of counterweight rings 413, thus counteracting the eccentric torque of the device and ensuring that the robot's climbing posture is upright and the force is balanced, preventing tilting or swaying during the ascent. After the device has climbed to the correct position, the clamping device 4 has gripped the pole and secured the insulating umbrella 1, when the operator is working at height, the position of the counterweight rings 413 on the counterweight rod 412 is changed by rotating the counterweight rings 413, causing the clamping device 4 to generate an eccentric load. This creates an adaptive force-increasing and self-locking effect where the greater the eccentric load, the tighter the grip, ensuring the reliability of the clamping device 4.

[0053] like Figure 10 As shown, the slot 411 has an open top and a closed bottom. The slot 411 is a right-angled trapezoid with a wider top and narrower bottom. The side wall of the slot 411 near the V-shaped clamping plate 45 has a right-angled waist. The shape of the plug 431 is adapted to the slot 411. The right-angled trapezoidal structure of the slot 411 guides the plug 431, facilitating quick alignment and assembly between the plug 431 and the slot 411. The right-angled waist near the V-shaped clamping plate 45 prevents the connecting frame 43 from separating from the V-shaped clamping block 41 after the clamping device 4 clamps the pole, ensuring the reliability of the clamping device 4.

[0054] like Figure 11 As shown, the telescopic mechanism 44 adopts a threaded self-locking electric push rod. After the clamping device 4 clamps the pole, the telescopic mechanism 44 does not need to be continuously powered, which avoids the clamping device 4 from failing due to power failure and further enhances the reliability of the clamping device 4.

[0055] like Figure 12 As shown, the V-shaped clamping plate 45 has several through slots 451 in the middle. Several eccentric wheels 452 are rotatably connected inside the through slots 451. The rotation center of the eccentric wheels 452 is set close to the V-shaped clamping block 41. After the pole is clamped, the minimum radial position of the eccentric wheel 452 abuts against the outer wall of the pole.

[0056] In the initial state of the device, the eccentric wheel 452 hangs down naturally under its own weight, which does not affect the normal alignment and clamping action of the clamping device 4. When the telescopic mechanism 44 drives the V-shaped clamping plate 45 to move closer to the pole and complete the clamping operation, the eccentric wheel 452 contacts the outer wall of the pole and is subjected to the squeezing force, and is forced to rotate around its own rotation center. Finally, it fits against the outer wall of the pole at the position of minimum radial distance. Since the pole has an inherent taper that is thinner at the top and thicker at the bottom, if the clamping device 4 has a downward tendency due to its own weight, wind force or other external forces, the eccentric wheel 452 will further clamp the outer wall of the pole with the downward displacement, forming a passive self-locking effect of the more it falls, the tighter it locks, which further ensures the stability of the installation of the insulating umbrella 1.

[0057] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
