Description

Technical Field

[0001] The present invention relates to the technical field of electric power maintenance, in particular to a high-altitude safety protection device for electric power maintenance. Background Art

[0002] Power maintenance refers to the daily maintenance and fault repair of power equipment. During power maintenance construction, it is often necessary to climb to the height of the power pole to carry out maintenance and repair work on power equipment, wires, etc. Usually, maintenance personnel will climb to the high altitude position of the power pole through the power pole climbing foot buckle, and carry out maintenance work after tying the safety rope.

[0003] According to a safety protection device for high-altitude operations in construction disclosed in patent No. CN115162761A, when one end of the safety rope is broken, the ratchet on the top of the installation groove will first contact the conveyor belt on the reset conveyor belt, increasing the friction between the safety rope and the conveyor belt, reducing the moving speed of the safety rope, and at the same time sounding the alarm. The conveying wheel and the extrusion groove will clamp the safety rope in the middle, and the ratchet in the extrusion groove will pierce and jam the safety rope, ensuring that the safety rope will not continue to move, thereby ensuring the safety of the safety rope during high-altitude operations.

[0004] However, during the implementation of the above solution, it is not convenient for maintenance personnel to fix the fixed end of the safety rope when climbing the utility pole. When maintenance personnel carry out maintenance work on power equipment and wires at a high place on the utility pole, during the process of climbing the utility pole, since the fixed end of the safety rope cannot be fixed in the middle position of the utility pole, the safety rope is generally wrapped around the utility pole, and the maintenance personnel lean back to increase the friction between the safety rope and the utility pole. After climbing to the highest position of the utility pole, the safety rope is fixed near the cross arm of the utility pole. However, if the safety rope is not fixed during the maintenance personnel's climbing process, the safety rope and the utility pole may easily fall off due to slipping, heat stroke or shock, causing the maintenance personnel to fall and get injured.

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 making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] The embodiment of the present invention provides a high-altitude safety protection device for power maintenance, such as Figure 1-7 As shown, it includes a fixed frame 1 and a mobile box 5. The fixed frame 1 is provided with a storage box adapted to the mobile box 5, so that the mobile box 5 can be placed in the storage box on the fixed frame 1 when not in use. A safety protection mechanism 2 is provided above the fixed frame 1. The safety protection mechanism 2 includes a take-up roller 21 rotatably connected to the inner wall of the fixed frame 1. The rotation of the take-up roller 21 is powered by a first forward and reverse motor provided externally. The fixed frame 1 is provided with a first battery to provide power for the first forward and reverse motor, and the first forward and reverse motor has a self-locking function.

[0032] The outer surface of the take-up roller 21 is fixedly connected to a safety rope 22, and a safety buckle is provided at the end of the safety rope 22 away from the take-up roller 21, which can be clamped by maintenance personnel. The outer surface of the mobile box 5 is fixedly connected to a support column 23, and the bottom surface of the support column 23 is fixedly connected to a pulley group 24. The pulley group 24 consists of a pulley and a bracket, and the pulley of the pulley group 24 is rotatably connected to the bracket of the pulley group 24.

[0033] The safety rope 22 is transmission-connected to the pulley block 24. The upper surface of the support column 23 is hinged with a hinged rod 25 through a pin shaft. The top end of the hinged rod 25 is fixedly connected to a buckle cover 26. The outer surface of the moving box 5 is hinged with a first electric push rod 27 through a pin shaft. The first electric push rod 27 can drive the hinged rod 25 to rotate when it is extended or retracted. The end of the first electric push rod 27 away from the moving box 5 is hinged to the outer surface of the hinged rod 25 through a pin shaft. The outer surface of the moving box 5 is fixedly connected to two symmetrical support rods 28. The ends of the two support rods 28 away from the moving box 5 are fixedly connected to the outer surface of the support column 23. The support rods 28 support the support column 23, making the support column 23 more stable.

[0034] Example 2:

[0035] Two symmetrical moving mechanisms 3 are provided inside the moving box 5. The moving mechanism 3 includes a first moving frame 31 and a second moving frame 32. The inner wall of the second moving frame 32 is rotatably connected to two first rotating rods 33. The outer surface of each first rotating rod 33 is fixedly connected to two symmetrical first rollers 34. The rotation of the first rollers 34 is powered by a second forward and reverse motor provided externally. The outer surface of each first rotating rod 33 is fixedly connected to a sprocket 35. The two sprockets 35 are connected by a chain transmission. Under the transmission action of the two sprockets 35 and the chain, the two first rotating rods 33 rotate synchronously.

[0036] The inner wall of the first mobile frame 31 is rotatably connected to a second rotating rod 36, and the outer surface of the second rotating rod 36 is fixedly connected to two symmetrical second rollers 37. The second rollers 37 play a positioning role for the mobile box 5, so that the mobile box 5 will not shake when moving on the telephone pole. The side of the first mobile frame 31 away from the second mobile frame 32 is fixedly connected to two second electric push rods 38. The ends of the two second electric push rods 38 away from the second mobile frame 32 are fixedly connected to the inner wall of the mobile box 5. Controlling the extension and retraction of the second electric push rods 38 can drive the first mobile frame 31 to move.

[0037] Two telescopic rods 39 are fixedly connected to a side of the first mobile frame 31 close to the second mobile frame 32, and the ends of the two telescopic rods 39 away from the first mobile frame 31 are fixedly connected to the outer surface of the second mobile frame 32.

The two first springs 310 are respectively sleeved on the outside of the two telescopic rods 39. The setting of the first springs 310 ensures that the second mobile frame 32 is always subjected to a force close to the electric pole when the moving box 5 moves, thereby causing friction between the first roller 34 and the electric pole.

[0038] Example 3:

[0039] A disassembly mechanism 4 is provided on the outside of the mobile box 5. The disassembly mechanism 4 includes a baffle 42 and two symmetrical guide rails 41. A second battery is provided on the baffle 42, which can provide power to the first electric push rod 27, the second electric push rod 38 and the second forward and reverse motor, and the electrical connection between the second battery and the first electric push rod 27, the second electric push rod 38 and the second forward and reverse motor is detachable. A counterweight is provided on the baffle 42 so that the center of gravity of the mobile box 5 is on the electric pole.

[0040] The two guide rails 41 are fixedly connected to the outer surface of the moving box 5, and the inner walls of the two guide rails 41 are slidingly connected to the outer surface of the baffle 42. The outer surface of the baffle 42 is provided with two symmetrical limiting holes 43. The outer surfaces of the two guide rails 41 are fixedly connected with a second spring 44. When the limiting rod 46 is inserted into the limiting hole 43, the second spring 44 is in a normal state. When the limiting rod 46 is pulled out of the limiting hole 43, the second spring 44 will be stretched. The second spring 44 can prevent the limiting rod 46 from being unintentionally detached from the limiting hole 43.

[0041] The two second springs 44 are fixedly connected to the operating disc 45 at one end away from the guide rail 41, and the two operating discs 45 are fixedly connected to the side of the guide rail 41 close to the limit rod 46. The two limit rods 46 pass through the two guide rails 41 at one end away from the operating disc 45 and extend into the interior of the two guide rails 41 respectively. The two limit rods 46 are slidingly connected to the two guide rails 41 respectively, and the two limit rods 46 are respectively adapted to the two limit holes 43. Inserting the limit rod 46 into the baffle 42 can prevent the baffle 42 from being unintentionally detached from the two guide rails 41.

[0042] Working principle:

[0043] During use, when it is necessary to inspect the power equipment on the utility pole, the fixed frame 1 is pushed to the utility pole so that the utility pole is located between the two moving mechanisms 3, and the operating disc 45 is pulled to stretch the second spring 44. At the same time, the limiting rod 46 leaves the internal space of the guide rail 41, and the baffle 42 is inserted between the two guide rails 41. At the same time, the operating disc 45 is released, and the limiting rod 46 is pushed to be inserted into the limiting hole 43 under the elastic force of the stretched second spring 44, controlling the second electric push rod 38 to extend, and the first moving frame 31 and the second moving frame 32 move toward the direction of the utility pole. After the first roller 34 contacts the utility pole, the first moving frame 31 continues to move toward the direction of the utility pole, so that the first spring 310 is compressed, and the telescopic rod 39 is in the shortest limit state. At the same time, the second roller 37 contacts the utility pole for positioning, and the external The second forward and reverse motor drives the first roller 34 to rotate, thereby moving the mobile box 5 upward on the telephone pole, and the pulley group 24 moves upward, driving the middle part of the safety rope 22 to move upward, controlling the first electric push rod 27 to shorten, causing the hinged rod 25 to rotate, and at the same time driving the buckle cover 26 to move above the top of the telephone pole, and controlling the mobile box 5 to move downward again, thereby buckling the buckle cover 26 on the top of the telephone pole. At this time, the safety buckle on the safety rope 22 is clamped on the maintenance personnel. When the maintenance personnel climb up, the wire take-up roller 21 is controlled to rotate to slowly retract the safety rope 22. The safety buckle on the safety rope 22 will slowly rise with the maintenance personnel. The first forward and reverse motor provided on the safety rope 22 has a self-locking function. When the maintenance personnel accidentally fall during the climbing process, the safety rope 22 can protect the maintenance personnel.
