Description

Technical Field

[0001] The present application relates to the technical field of electric wire maintenance, and more specifically, to a climbing robot for electric wire maintenance. Background Art

[0002] With the rapid economic growth, electricity and the Internet have become increasingly critical in modern people's work and life. The installation and maintenance of wires and cables have become vital tasks to ensure the smooth flow of electricity and the Internet. With the continuous development of power technology, many high-pole facilities related to commercial or municipal engineering, such as utility poles, have appeared in urban and rural areas. When the wires on the utility poles are damaged and need to be repaired, the traditional practice is to rely on manual labor with special tools to perform live operations. However, this method has some problems, including harsh working environment, high labor intensity, and strong electric fields that pose a threat to the personal safety of operators. In order to solve these problems, climbing robots are currently used to inspect and repair transmission lines.

[0003] When existing maintenance climbing robots climb on rainy days or in humid conditions such as rain, ice and snow, the climbing robots may lose their firm attachment to the poles and slip or detach, causing the robots to fall from the poles, posing serious safety risks and causing damage to the robots themselves, delaying the completion of maintenance, inspection or other tasks, and affecting overall efficiency. Utility Model Content

[0004] In order to solve the above problems, the present application provides a climbing robot for wire maintenance.

[0005] The present application provides a climbing robot for wire maintenance using the following technical solution:

[0006] A climbing robot for electric wire maintenance comprises a first climbing board, the bottom of which is provided with an anti-falling assembly;

[0007] The anti-falling component includes multiple groups, each group of anti-falling components includes a shell, a ratchet is arranged inside the shell, a spring is fixedly connected to one side of the shell, a pawl is rotatably connected to one end of the shell close to the ratchet, one end of the spring is fixedly connected to the pawl, and the ratchet cooperates with the pawl.

[0008] Through the above technical solution, the cooperation between the ratchet and the pawl can lock the rotating wheel when the first climbing board and the second climbing board slip. The friction generated between the rotating wheel and the pole can prevent the climbing robot from falling, thereby improving the stability and climbing efficiency in rainy and snowy weather.

[0009] Furthermore, one end of each pawl away from the ratchet is fixedly connected to an iron block, an electromagnet is provided between the iron block and the ratchet, and the electromagnet is magnetically connected to the iron block.

[0010] Through the above technical solution, when the electromagnet is energized, the iron block will be attracted by the electromagnet, and the pawl will rotate and disengage from the ratchet wheel, so that the ratchet wheel can rotate freely and descend.

[0011] Furthermore, the bottom of the first climbing board is fixedly connected to the two L-shaped rods, and one side of the first climbing board is provided with two fixing rings, one of which is fixedly connected to the two L-shaped rods, and the two fixing rings are connected by fixing bolts.

[0012] Through the above technical solution, the bolt connection facilitates the disassembly and installation of the fixing ring.

[0013] Furthermore, two rotating rods are rotatably connected to the inner sides of the two fixed rings, a rotating wheel is fixedly connected to the outer wall of each rotating rod, a rubber sleeve is fixedly connected to the outer wall of each rotating wheel, and a plurality of friction grooves are provided on the outer wall of each rubber sleeve.

[0014] Through the above technical solution, the rubber sleeve can provide a certain friction force to prevent sliding and instability.

[0015] Furthermore, one end of each rotating rod extends through the interior of the corresponding housing and is fixedly connected to the ratchet, and each electromagnet is fixedly connected to the corresponding housing.

[0016] Through the above technical solution, when the climbing robot is climbing, the rotating wheels will also rotate synchronously.

[0018] Through the above technical solution, when the motor is started, it will drive the connecting rod to rotate, and the rotation of the connecting rod pushes the second climbing board to slide upward on the sliding rod.

[0019] Furthermore, electric cylinders are provided at the bottom of the first climbing board and the top of the second climbing board, cross rods are provided at the output ends of the two electric cylinders, the shafts inside the two cross rods are rotatably connected to the first climbing board and the second climbing board respectively, and clamping arms are rotatably connected at both ends of the two cross rods.

[0020] Through the above technical solution, when the climbing robot is repairing the utility pole, the clamping arm provides clamping and stable support for the utility pole.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] (1) The utility model can prevent the climbing robot from slipping and falling off when the electric pole is damp in rainy and snowy weather by setting an anti-fall component. Specifically, the rotating wheel rotates following the movement of the first climbing board and the second climbing board. Because the ratchet and pawl on one side of the rotating rod inside the rotating wheel can only transmit in one direction, the rotating wheel can be locked when the climbing board slips. The friction force generated between the rotating wheel and the electric pole prevents the climbing robot from falling, thereby improving the stability and climbing efficiency in rainy and snowy weather.

[0023] (1) When the climbing robot of the utility model descends, the electromagnet is energized, and the iron block is attracted by the electromagnet. At this time, the ratchet rotates and disengages from the ratchet wheel, and the ratchet wheel can rotate freely to achieve descent;

[0024] (2) The utility model can provide a certain friction force by setting the rubber sleeve on the outside of the rotating wheel to prevent sliding and instability. It can also better adapt to the shape of the surface of the utility pole and improve the gripping force of the rotating wheel on the utility pole. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0032] Reference Figure 1-Figure 5 , a climbing robot for electric wire maintenance, comprising a first climbing board 1, wherein an anti-falling component is provided at the bottom of the first climbing board 1;

[0033] The anti-falling assembly includes multiple groups, each group of anti-falling assembly includes a shell 13, a ratchet 14 is provided inside the shell 13, a spring 17 is fixedly connected to one side of the shell 13, and a pawl 16 is rotatably connected to one end of the shell 13 close to the ratchet 14, one end of the spring 17 is fixedly connected to the pawl 16, and the ratchet 14 cooperates with the pawl 16.

[0034] By setting up the anti-fall component, the climbing robot can be prevented from slipping and falling off when the utility poles become damp in rainy and snowy weather, thereby improving the stability and climbing efficiency in rainy and snowy weather.

[0035] Reference Figure 4-Figure 5 One end of each pawl 16 away from the ratchet 14 is fixedly connected to an iron block 18 , and an electromagnet 19 is provided between the iron block 18 and the ratchet 14 , and the electromagnet 19 is magnetically connected to the iron block 18 .

[0036] When the climbing robot descends, the electromagnet 19 is energized, and the iron block 18 will be attracted by the electromagnet 19. At this time, the pawl 16 rotates and then disengages from the ratchet 14, and the ratchet 14 can rotate freely to achieve descent.

[0037] Reference Figure 2-Figure 3 The bottom of the first climbing board 1 is fixedly connected to two L-shaped rods 9, and one side of the first climbing board 1 is provided with two fixing rings 10, one of which is fixedly connected to the two L-shaped rods 9, and the two fixing rings 10 are connected by fixing bolts, and the inner sides of the two fixing rings 10 are rotatably connected to two rotating rods 15, and the outer wall of each rotating rod 15 is fixedly connected to a rotating wheel 11, and the outer wall of each rotating wheel 11 is fixedly connected to a rubber sleeve 12, and the outer wall of each rubber sleeve 12 is provided with a plurality of friction grooves.

[0038] When it is necessary to climb a utility pole, first clamp and fix the utility pole with the clamping arms 8 on both sides of a cross rod 7. At this time, the fixing ring 10 on one side surrounds one side of the utility pole, and the other fixing ring 10 is installed with the fixing ring 10 surrounding one side of the utility pole through fixing bolts, so that the internal rotating wheel 11 is close to the surface of the utility pole.

[0039] The rubber sleeve 12 outside the rotating wheel 11 is made of rubber material, which can provide a certain friction force to prevent sliding and instability, and can also better adapt to the shape of the surface of the telephone pole and improve the gripping force of the rotating wheel 11 on the telephone pole.

[0040] Reference Figure 4-Figure 5One end of each rotating rod 15 extends through the interior of the corresponding housing 13 and is fixedly connected to the ratchet 14 , and each electromagnet 19 is fixedly connected to the corresponding housing 13 .

[0041] When the first climbing board 1 climbs upward, it will drive the rotating wheel 11 to rotate, and the rotation of the rotating wheel 11 will drive the ratchet 14 to rotate. Because the ratchet 14 and the pawl 16 are one-way transmission, when the first climbing board 1 and the second climbing board 2 suddenly slip or separate, it can prevent the first climbing board 1 and the second climbing board 2 from falling backward.

[0042] Reference Figure 1-Figure 2 A motor 3 is provided on the top of the first climbing board 1, and a connecting rod 4 is fixedly connected to the output end of the motor 3. One end of the connecting rod 4 is connected to the second climbing board 2. Sliding rods 5 are fixedly connected to the four sides of the first climbing board 1. The second climbing board 2 is slidably connected to multiple sliding rods 5. Electric cylinders 6 are provided at the bottom of the first climbing board 1 and the top of the second climbing board 2. Cross rods 7 are provided at the output ends of the two electric cylinders 6. The shafts inside the two cross rods 7 are rotatably connected to the first climbing board 1 and the second climbing board 2 respectively, and clamping arms 8 are rotatably connected to both ends of the two cross rods 7.

[0043] When it is necessary to repair the wires on the utility pole, first the clamping arm 8 at the bottom of the first climbing board 1 clamps the utility pole, then the motor 3 is started, and the output end of the motor 3 drives the connecting rod 4 to rotate, and the connecting rod 4 rotates to push the second climbing board 2 to slide upward on the sliding rod 5. At this time, the electric cylinder 6 on the second climbing board 2 is started to pull the cross rod 7 to move backward, and the front end clamping arm 8 of the cross rod 7 will clamp inward, and then the motor 3 is started again. Because the second climbing board 2 is in a fixed state, the motor 3 drives the first climbing board 1 to move upward through the connecting rod 4 when it is started, and then the utility pole is clamped by the clamping arm 8 of the first climbing board 1, and the first climbing board 1 and the second climbing board 2 move upward alternately to achieve climbing of the utility pole.

[0044] Working principle: When repairing a telephone pole, first, the clamping arm 8 at the bottom of the first climbing board 1 clamps the telephone pole. At this time, the fixing ring 10 on one side surrounds one side of the telephone pole. The other fixing ring 10 is installed with the fixing ring 10 surrounding one side of the telephone pole through the fixing bolts, so that the internal rotating wheel 11 is close to the surface of the telephone pole. Then, the motor 3 is started, and the upper sliding rod 5 of the second climbing board 2 is pushed to slide upward through the connecting rod 4. Then, the electric cylinder 6 on the second climbing board 2 is started, and the cross rod 7 is pulled to make the clamping arm 8 clamp the telephone pole. Then, the motor 3 is started again. Since the second climbing board 2 is fixed, the first climbing board 1 is driven to move upward through the connecting rod 4, and the clamping arm 8 of the first climbing board 1 also clamps the telephone pole. In this way, the first climbing board 1 and the second climbing board 2 are moved up alternately to realize climbing of the telephone pole. While climbing, the rotating wheel 11 will also rotate synchronously;

[0045] When encountering rainy and snowy weather and the telephone poles are damp, since the ratchet 14 and pawl 16 inside the rotating wheel 11 are one-way transmission, if the first climbing board 1 and the second climbing board 2 suddenly slip or disengage, the rotating wheel 11 will be locked, and the friction generated between the rotating wheel 11 and the telephone pole prevents the climbing robot from falling, thereby increasing the stability of the climbing robot in damp conditions and preventing accidental backward movement. When it is necessary to descend, the electromagnet 19 is energized, the iron block 18 will be attracted by the electromagnet 19, and the pawl 16 will rotate at this time, thereby disengaging from the ratchet 14, and the ratchet 14 can rotate freely to achieve descent.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
