Description

Technical Field

[0002] With the rapid development of society, people have higher and higher requirements for power supply reliability, and live working is one of the important means to improve reliability; the current equipotential live working tools mainly include flying cars, soft ladders, flip pulleys and related devices such as insulation matching; the pulley is a common live working tool in the equipotential operation process. When dealing with broken strands of wires, wire adhesion, foreign matter in wires, and installing or replacing spacers and shock-proof hammers, it is necessary to enter the strong electric field through an insulating soft ladder to implement equipotential operations. During the operation, when the pulley is used to hang the overhead wire, it is easy to fall off the hook of the insulating operating rod, resulting in high-altitude falling objects, especially for high-voltage transmission lines with an operating distance of more than 3m, 220kV or even 500kV. And the high-altitude falling objects and tool damage caused by the pulley hanging not only delay the progress of the maintenance work and increase the difficulty of the work, but also increase the safety hazards of ground workers.

The sizes of the wire inlet groove 2 and the wire outlet groove 4 are slightly larger than the obstacle, so that the obstacle can pass through the wire inlet groove 2 and the wire outlet groove 4. The wire outlet groove 4 and the wire inlet groove 2 are on the same straight line. The transmission line (not shown in the figure) enters from the wire inlet groove 2 and exits from the wire outlet groove 4. A protective plate 1 located above the wire inlet groove 2 and the wire outlet groove 4 is fixedly provided on the upper side of the suspension plate 1. 8. A single chip microcomputer 19 is arranged on the upper side of the protective plate 18. An ultrasonic sensor 20 is arranged on the side of the suspension plate 1 close to the line inlet slot 2. The ultrasonic sensor 20 can detect whether there is an obstacle in the transmission line. When an obstacle is detected, the signal will be fed back to the single chip microcomputer 19. The single chip microcomputer 19 controls the pulley to cross the obstacle. A manned bracket is arranged on the lower side of the suspension plate 1. The manned bracket includes a detachable lifting ring 10 on both sides of the suspension plate 1. The lifting ring 10 is detachably connected to the suspension plate 1 by bolts. The two lifting rings are connected to the suspension plate 1 by bolts. A vertical rod 11 is fixedly arranged on the lower side of the ring 10, and a handrail 12, a seat rod 13 and a footrest rod 14 are fixedly arranged between the two vertical rods 11 from top to bottom. The handrail 12, the seat rod 13 and the footrest rod 14 are fixed between the two vertical rods 11 by bolts. The handrail 12, the seat rod 13 and the footrest rod 14 are covered with rubber sleeves (not shown in the figure). The rubber sleeves can increase the friction between the personnel and improve the safety. The handrail 12 adopts a vertically arranged arc rod, and the seat rod 13 adopts a horizontally arranged arc rod. An arc-shaped rod, the pedal rod 14 adopts a horizontal straight rod, a battery box 15 is fixedly arranged between the bottoms of the two vertical rods 11, and a battery (not shown in the figure) is arranged in the battery box 15. The battery is used for power supply, and a switch (not shown in the figure) is arranged on the lifting ring 10. When in use, a person sits on the horizontal arc-shaped sitting rod 13, holds the handrail 12 with his hands, and steps on the pedal rod 14 with his feet, so that the person can sit stably on the manned support, which is convenient for the person to perform high-voltage operations and improves the safety of the operation.

[0035] like Figure 1 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 , Fig.13As shown, two groups of obstacle-crossing driving mechanisms 3 are arranged on the upper side of the suspension plate 1, the two groups of obstacle-crossing driving mechanisms 3 are identical, and the two groups of obstacle-crossing driving mechanisms 3 are arranged in sequence along the direction of the transmission line.

The driving wheels 302 are driven to rotate by the driving motor 301. Since the driving wheels 302 roll on the transmission line, the suspension plate 1 and the manned bracket on the lower side of the suspension plate 1 can be driven to move under the transmission line, which is convenient for personnel to perform live operations. The suspension plate 1 is provided with a through groove 101 that cooperates with the driving motor 301. The through groove 101 facilitates the passage of the driving motor 301. A lifting motor 306 is fixedly arranged on the upper side of the suspension plate 1. A gear 305 is fixedly provided at the output end of the lifting motor 306, and a rack 304 fixedly provided on one side of the lifting plate 303 is meshed with one side of the gear 305. A guide hole 102 that slides with the lifting plate 303 is provided on the suspension plate 1, and a buffer groove 1701 is provided on the lower side of the lifting plate 303. A buffer spring 1702 that is fixedly connected to the suspension plate 1 is fixedly provided at the bottom of the buffer groove 1701. The rack 304 on one side of the lifting plate 303 can be pressed tightly against the surface of the gear 305 through the buffer spring 1702. The lifting plate 303 is lifted up by the lifting motor 306, so that the driving motor 301 and the driving wheel 302 on one side of the lifting plate 303 are lifted up on the transmission line together, so that the driving wheel 302 can pass over the obstacle on the transmission line. The obstacle can be passed without stopping the pulley, thereby improving the use efficiency of the pulley.

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.10 , Fig.11 , Fig.12As shown, a long rod 5 is rotatably provided on one side of the suspension plate 1, and a first clamping wheel 6 cooperating with the transmission line is rotatably provided on one end of the long rod 5, and a short rod 7 is rotatably provided on one side of the suspension plate 1. The short rod 7 and the long rod 5 are both located on a side close to the outlet groove 4, and the length of the short rod 7 is less than the length of the long rod 5. A second clamping wheel 8 cooperating with the transmission line is rotatably provided on one end of the short rod 7, and a tension driving mechanism 9 for simultaneously driving the long rod 5 and the short rod 7 to open and close is provided on one side of the suspension plate 1. The tension driving mechanism 9 includes a fixed cylinder 901 fixedly provided on one side of the suspension plate 1, a screw rod 903 is rotatably provided on the inner side of the fixed cylinder 901, and an adjusting motor 902 for driving the screw rod 903 to rotate is fixedly provided on one side of the fixed cylinder 901, a threaded sleeve 904 is threadedly sleeved on the screw rod 903 and slidably connected to the inner side of the fixed cylinder 901, and a threaded sleeve 904 is rotatably provided on one side of the threaded sleeve 904. The first pull rod 905 is rotatably connected, and the other side of the threaded sleeve 904 is rotatably provided with a second pull rod 906 rotatably connected to the short rod 7. When in use, when the two driving wheels 302 on the suspension plate 1 are hung on the transmission line, the screw rod 905 is driven to rotate by adjusting the motor 902, so that the threaded sleeve 904 slides linearly on the inner side of the fixed cylinder 901, so that the threaded sleeve 904 drives the first pull rod 905 and the second pull rod 906 on both sides to move, so that the first pull rod 905 and the second pull rod 906 can respectively drive the long rod 5 and the short rod 7 to approach each other, so that the first clamping wheel 6 and the second clamping wheel 8 at one end of the long rod 5 and the short rod 7 are staggered and clamped on both sides of the transmission line, and the first clamping wheel 6 and the second clamping wheel 8 are staggered and matched with each other, so that the first clamping wheel 6 and the second clamping wheel 8 are decelerated on the transmission line, the speed of the pulley is controlled, and the safety of personnel is ensured.

[0037] like Figure 4 , Figure 5 , Figure 6 , Fig.11 , Fig.12 As shown, a dirt removal mechanism 16 cooperating with the transmission line is provided in the middle of the long rod 5 and the short rod 7. The dirt removal mechanism 16 includes a rib plate 1601 fixedly provided in the middle of the long rod 5 and the short rod 7. A threaded rod 1602 is threadedly provided on the rib plate 1601. A transfer base 1603 is rotatably provided at one end of the threaded rod 1602. An arc plate 1604 cooperating with the transmission line is fixedly provided on one side of the transfer base 1603. When in use, the long rod 5 and the short rod 7 are pulled closer to each other by the first pull rod 905 and the second pull rod 906 respectively, and the threaded rods 1602 on the long rod 5 and the short rod 7 are brought closer to each other at the same time, so that the arc plates 1604 at one end of the two threaded rods 1602 are brought closer to each other, so that the two arc plates 1604 are closely attached to the two sides of the transmission line. When the pulley moves, the two arc plates 1604 can be driven to slide on the surface of the transmission line, so that pollutants (such as bird droppings, plastic bags, etc.) on the surface of the transmission line are scraped off to prevent affecting the safety of the transmission line.

[0038] It should be noted that, when using this automatic pulley for overcoming obstacles during live working, first hang the inlet groove 2 and the outlet groove 4 at both ends of the lower side of the suspension plate 1 on the transmission line, so that the two driving wheels 302 located between the inlet groove 2 and the outlet groove 4 on the upper side of the suspension plate 1 can be hung on the transmission line. During transportation, the driving motor 301 drives the driving wheel 302 to rotate, so that the suspension plate 1 can be transported on the transmission line, and then the manned bracket on the lower side of the suspension plate 1 can be moved together, so that the person on the manned bracket can perform live working. When the ultrasonic sensor 20 detects an obstacle, it will feed back a signal to the single-chip microcomputer 19. If the pulley speed is too fast, the single-chip microcomputer 19 will control the adjusting motor 902 to make the adjusting motor 902 work, thereby driving the screw rod 903 to rotate, and then the threaded sleeve 904 slides linearly on the inner side of the fixed cylinder 901, so that the threaded sleeve 904 drives the first pull rod 905 and the second pull rod 906 on both sides to move , the first pull rod 905 and the second pull rod 906 can respectively drive the long rod 5 and the short rod 7 to approach each other, so that the first clamping wheel 6 and the second clamping wheel 8 at one end of the long rod 5 and the short rod 7 are staggered and clamped on both sides of the transmission line, so that the pulley slows down, and then the single-chip microcomputer 19 controls the lifting motor 306 near the side of the incoming line slot 2 to work, and the lifting motor 306 drives the gear 305 to rotate, thereby raising the rack 304, driving the lifting plate 303 to rise, so that the driving motor 301 and the driving wheel 302 on one side of the lifting plate 303 are raised together on the transmission line, so that the driving wheel 302 near the side of the incoming line slot 2 passes over the obstacle on the transmission line, and then the pulley slides for a distance, and the single-chip microcomputer 19 controls the lifting motor 306 near the side of the outgoing line slot 4 to work, and similarly makes the driving wheel 302 near the side of the outgoing line slot 4 pass over the obstacle on the transmission line, so that the entire pulley can quickly pass over the obstacle, thereby improving the efficiency and safety of the pulley.

[0039] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
