Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power inspection technology, and specifically relates to a power inspection auxiliary device. Background Technology
[0002] Power line inspection is a task used to regularly or in real-time monitor, inspect and maintain power facilities such as transmission lines, substations and power distribution equipment. Its core objective is to ensure the safe and stable operation of the power grid, prevent equipment failures (such as line breaks, insulation aging, and overheating of joints), and assess the operating status of the facilities.
[0003] While drones can be used for overhead cable inspections, they can only perform basic image acquisition. Detailed inspections and maintenance still require manual labor. Common overhead cables typically consist of four or six parallel cables, with spacers placed at intervals to restrict cable movement and ensure stable cable arrangement. Currently, manual inspections usually involve connecting a cable with a safety rope and safety buckle. Inspectors typically walk on the lower cable and hold onto the upper cable to move forward. This method is strenuous, unstable, and not conducive to fast and stable passage on overhead cables, resulting in relatively low inspection efficiency. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide an auxiliary device for power line inspection, which solves the problem that when conducting manual inspections, a cable is usually connected by a safety rope and safety buckle. The inspector usually steps on the lower cable and holds the upper cable to move forward for inspection. This method of moving forward is relatively strenuous and unstable, making it inconvenient to move quickly and stably on overhead cables, resulting in relatively poor inspection efficiency for overhead cables.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power inspection auxiliary device, comprising a base rod, with a through-groove groove at both ends of the upper side of the base rod, through which a nylon belt is threaded. The end of the nylon belt passes through the through-groove groove and is fixedly connected to itself. A hook is provided at the upper end of the nylon belt, the hook including a hook plate. A through-groove groove is provided on the lower side of the hook plate, through which the upper end of the nylon belt passes and is fixedly connected to itself. A fixing plate is fixedly provided on the upper side of the hook plate that is far apart from each other. A vertical plate is fixedly connected to the lower side of the fixing plate that is far apart from each other. Rollers are arranged side by side and rotatably on the upper side of the vertical plate and the hook plate that are close to each other.
[0006] The beneficial effects of this utility model are: it eliminates the need for inspectors to step on the cable to move forward; they can sit directly on the support pole and move forward by rolling on the rollers. This not only ensures stability but also facilitates movement, allowing inspectors to pass quickly and stably on the cable, thereby increasing the efficiency of cable inspection.
[0007] To prevent the cable from easily falling out of the hook;
[0008] As a further improvement to the above technical solution: an elastic baffle is fixedly provided on the lower side of the side of the upright plate near the hook plate, and the side of the elastic baffle away from the upright plate is close to the hook plate.
[0009] The beneficial effects of this improvement are as follows: by setting up an elastic baffle, when hooking, the elastic baffle is directly squeezed to deform it and the cable is inserted. When removing, the cable can be removed by pressing the elastic baffle to deform it. It can also prevent the cable from falling out of the hook.
[0010] In order to control the forward speed;
[0011] As a further improvement to the above technical solution: a bolt is inserted into the center of the upper side of each fixing plate, the lower end of the bolt passes through to the lower side of the fixing plate and is threaded to a friction plate, a spring is sleeved on the outer side of the bolt, a connecting block is fixedly installed on the side of the bolt near the hook plate, a connecting plate is fixedly installed on the lower side of the end of the connecting block away from the bolt, and a handle is fixedly installed on the lower side of the side of the connecting plates that are close to each other.
[0012] The beneficial effects of this improvement are as follows: When going downhill on a long slope, by pulling down the connecting plate with the handle, the connecting block drives the bolt to press down the friction plate, which can brake the roller by rubbing against it, thereby controlling the forward speed.
[0013] To increase its friction with the cable;
[0014] As a further improvement to the above technical solution: the outer side of the roller is covered with a hard rubber layer.
[0015] The beneficial effect of this improvement is that it increases the friction between the cable and the wire, making it less likely to slip relative to the cable.
[0016] To increase the stability of the bolt's vertical movement;
[0017] As a further improvement to the above technical solution: a limiting plate is fixedly provided on the upper side of the fixed plate near the edge of the hook plate, and a sliding groove is provided through the middle of the side of the limiting plate, and the connecting block is slidably engaged with the limiting plate through the sliding groove.
[0018] The beneficial effects of this improvement are as follows: the setting of a limiting plate and the sliding engagement of the connecting block with the limiting plate through the sliding groove are used to increase the stability of the bolt's up and down movement and make the bolt less prone to bending under lateral force.
[0019] To increase the wear resistance of the upper and lower joints of the nylon belt;
[0020] As a further improvement to the above technical solution: metal sheets are bonded to the inner sides of the bends at both ends of the nylon belt where it connects to the seat post and hook plate.
[0021] The beneficial effect of this improvement is that the metal sheet is added to increase the wear resistance of the upper and lower joints of the nylon belt.
[0022] To increase comfort to some extent;
[0023] As a further improvement to the above technical solution: silicone pads are adhered to the upper side of each seat post.
[0024] The beneficial effect of this improvement is that it increases comfort to a certain extent.
[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0032] like Figure 1— Figure 4As shown: A power inspection auxiliary device includes a base pole 1. Both ends of the upper side of the base pole 1 have through-grooves 2. A nylon strap 3 is threaded through the through-grooves 2 onto the base pole 1. The end of the nylon strap 3 passes through the through-grooves 2 and is fixedly connected to itself. A hook 4 is provided at the upper end of the nylon strap 3. The hook 4 includes a hook plate 41. The lower side of the hook plate 41 has through-grooves 42. The upper end of the nylon strap 3 passes through the through-grooves 42 and is fixedly connected to itself. A fixing plate is fixedly provided on the upper side of the hook plate 41 that is far apart from the other sides. 43. Each of the fixed plates 43 has a vertical plate 44 fixedly connected to its lower side at the ends that are far apart from each other. Rollers 45 are arranged side by side and rotate on the upper side of the vertical plate 44 and the hook plate 41 that are close to each other. This allows the inspector to move forward without stepping on the cable, but instead sit directly on the seat 1 and roll forward using the rollers 45. This is not only stable but also convenient, facilitating quick and stable passage for the inspector on the cable, thus increasing the efficiency of the inspector's cable inspection. An elastic baffle 46 is fixedly installed on the lower side of the vertical plate 44 near the hook plate 41. The elastic baffle 46 is located on the side of the vertical plate 44 away from the vertical plate 44 and close to the hook plate 41. When hooking, the elastic baffle 46 is directly squeezed. The elastic baffle 46 deforms, causing the cable to be inserted. To remove it, press the elastic baffle 46 to deform it and remove the cable. It also prevents the cable from falling out of the hook 4. A bolt 47 is inserted into the center of the upper side of each fixing plate 43. The lower end of the bolt 47 passes through the lower side of the fixing plate 43 and is threaded with a friction plate 49. A spring 48 is sleeved on the outer side of the bolt 47. A connecting block 410 is fixedly installed on the side of the bolt 47 closest to the hook plate 41. A connecting plate 411 is fixedly installed on the lower side of the end of the connecting block 410 away from the bolt 47. The connecting plates 411 are close to each other. Handles 412 are fixedly installed on the lower side of each side. When descending a long slope, the connecting plate 411 is pulled down by the handles 412, and then the connecting block 410 drives the bolt 47 to press down the friction plate 49. The friction plate 49 can brake the roller 45 by rubbing against it, thereby controlling the forward speed. The outer side of the roller 45 is covered with a hard rubber layer to increase its friction with the cable and make it less likely to slip relative to the cable. A limit plate 413 is fixedly installed on the upper side of the fixed plate 43 near the edge of the hook plate 41. A sliding groove is opened through the middle of the side of the limit plate 413. The connecting block 410 is slidably engaged with the limit plate 413 through the sliding groove.The connecting block 410 slides and engages with the limiting plate 413 via a groove, increasing the stability of the bolt 47's vertical movement and preventing it from bending under lateral forces. Metal sheets 31 are bonded to the inner sides of the bends at both ends of the nylon strap 3 where it connects to the seat post 1 and hook plate 41. These metal sheets 31 increase the wear resistance of the upper and lower connections of the nylon strap 3. Silicone pads 5 are bonded to the upper side of the seat post 1, increasing comfort to some extent.
[0033] Working principle and usage process of this utility model:
[0034] In use, the hooks 4 of this device are hooked onto the two parallel cables on the upper side, and the rollers 45 press directly on the upper side of the cables. The hook plate 41 and the upright plate 44 are located on both sides of the hooked cables. The inspector sits directly on the upper side of the seat 1, with his feet straddling the two parallel cables below. At this time, the inspector holds the upper end of the nylon belt 3 with both hands and pushes the nylon belt 3 left and right. The nylon belt 3 drives the hooks 4 to roll forward along the cables via the rollers 45. In addition, when inspecting, the inspector generally prefers to start from... When inspecting cables from high towers to low ones, the cables are generally in a downward-sloping state. When encountering a long downhill slope, the inspector can sit directly on the support pole 1 and slide along the cable using the roller 45 to move forward quickly. When encountering a cable barrier, the inspector can simply remove the hook 4 from the cable. There is no need for the inspector to step on the cable to move forward; they can sit directly on the support pole 1 and roll forward using the roller 45. This method is not only stable but also convenient, allowing the inspector to move quickly and stably along the cable, thereby increasing the efficiency of the cable inspection. In addition, an elastic baffle 46 is fixedly installed on the lower side of the side of the upright plate 44 near the hook plate 41. The side of the elastic baffle 46 away from the upright plate 44 is close to the hook plate 41. When hooking, the elastic baffle 46 is directly squeezed to deform it, and the cable is inserted. When removing, the cable can be removed by pressing the elastic baffle 46 to deform it. It can prevent the cable from falling out of the hook 4. In addition, when going down a long slope, the connecting plate 411 is pulled down by the handle 412, and then the connecting block 410 drives the bolt 47 to press down the friction plate 49. The roller 49 can be braked by friction roller 45 to control the forward speed. In addition, the outer side of roller 45 is covered with a hard rubber layer to increase its friction with the cable and make it less likely to slip relative to the cable. In addition, a limiting plate 413 is provided, and the connecting block 410 is slidably engaged with the limiting plate 413 through a sliding groove to increase the stability of the bolt 47 moving up and down and make the bolt 47 less likely to bend under lateral force. In addition, a metal sheet 31 is provided to increase the wear resistance of the upper and lower connection of the nylon belt 3. In addition, silicone pads 5 are adhered to the upper side of the seat bar 1 to increase comfort to a certain extent.
