[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6 The present invention provides the following technical solution:
[0027] A high-altitude power maintenance equipment includes a base plate 1, a protective basket 5 placed on top of the base plate 1, electric telescopic rods 4 fixedly connected to the four corners of the top of the base plate 1, a support mechanism 2 provided at the bottom of the base plate 1, and a rotating door mechanism 3 provided at the front of the protective basket 5.
[0028] The support mechanism 2 includes a fixed column 201, a fixed frame 202, an elastic pad 203, several limiting cones 204 and rollers 205. The top of the fixed column 201 is fixedly connected to the bottom of the base plate 1. The fixed column 201 is movably connected inside the fixed frame 202. The top of the fixed frame 202 is fixedly connected to the top of the rollers 205. The bottom of the elastic pad 203 is fixedly connected to the top of the rollers 205. The bottom of the fixed column 201 is in contact with the top of the elastic pad 203.
[0029] Specifically, such as Figure 3 and Figure 6 As shown, a support arm 16 is provided at the bottom of the base plate 1, the top of the limiting cone 204 is fixedly connected to the bottom of the support arm 16, a rotating block 15 is provided at the bottom of the support arm 16, the top of the rotating block 15 passes through the support arm 16 and is fixedly connected to the bottom of the base plate 1, and the surface of the rotating block 15 is movably connected to the interior of the support arm 16.
[0030] Specifically, such as Figure 2 and Figure 6 As shown, a limit button 14 is provided at the bottom of the support arm 16. The top of the limit button 14 passes through the support arm 16 and extends into the interior of the base plate 1. The surface of the limit button 14 is threadedly connected to the interior of the support arm 16.
[0031] Specifically, such as Figure 1 and Figure 5 As shown, a connecting block 10 is fixedly connected to the top of the telescopic end of the electric telescopic pole 4, and a fixing block 11 is fixedly connected to each of the four corners of the top of the protective basket 5. The side of the connecting block 10 closest to the fixing block 11 is fixedly connected to the fixing block 11.
[0032] In this embodiment: the small protective basket 5 and base plate 1 can be easily moved into a confined space by holding the handle 6. Then, the limit button 14 is turned so that the limit button 14 is disengaged from the base plate 1, and the support arm 16 can be unfolded to the outside of the base plate 1. At this time, the staff enters the protective basket 5 and presses down on the protective basket 5 and the base plate 1, so that the fixed column 201 squeezes the elastic pad 203, so that the limit cone 204 is in close contact with the ground, thus stabilizing and supporting the base plate 1 and the protective basket 5. By simultaneously controlling the extension ends of the four electric telescopic rods 4 to extend upward, the protective basket 5 and the interior of the protective basket 5 can be lifted. No large power vehicle is required to provide power, which is convenient for the maintenance of power lines in confined spaces.
[0033] Specifically, such as Figure 4 As shown, the revolving door mechanism 3 includes a rotating rod 301, two handles 302, a first limiting block 303, and a door panel 304. The bottom of the rotating rod 301 passes through the door panel 304 and is fixedly connected to the bottom of the inner wall of the protective basket 5. The surface of the rotating rod 301 is movably connected to the interior of the door panel 304. The rear side of the first limiting block 303 is fixed to the front side of the door panel 304.
[0034] Specifically, such as Figure 4 and Figure 5 As shown, the protective basket 5 has two fixedly connected second limiting blocks 13 on both sides of the front side, and the bottom plate 1 has two limiting pins 12 on both sides of the top. The limiting pins 12 are movably inserted between the first limiting block 303 and the second limiting block 13.
[0035] In this embodiment: by pulling the limit pin 12 upward to extend the first limit block 303 and the second limit block 13, the handle 302 can be held to rotate the door panel 304 around the rotating rod 301, which facilitates maintenance personnel to enter the protective basket 5. Then, by resetting the limit pin 12, the door panel 304 can be closed.
[0036] Specifically, such as Figure 1 As shown, hangers 8 are fixedly connected to both sides of the top of the base plate 1, and a hanging ring 7 is fixedly connected to the top of the hanger 8. A handrail 6 is fixedly connected to the rear side of the top of the protective basket 5.
[0037] Specifically, such as Figure 3 As shown, both the protective basket 5 and the door panel 304 have through holes 9 inside. There are several through holes 9, which are evenly distributed inside the protective basket 5 and the door panel 304.
[0038] In this embodiment: by using external hoisting equipment and external connecting ropes to connect with the lifting ring 7, it is convenient to hoist the base plate 1 and the protective basket 5 together for long-distance transportation or for higher lifting. The through hole 9 facilitates airflow and prevents the protective basket 5 from being affected by wind and thus its stability.
[0039] Working principle: By pushing the handle 6, the rollers 205 rotate, allowing the relatively small base plate 1 and protective basket 5 to be moved into confined spaces for preparation. Then, by rotating the limit button 14, which is threadedly connected to the inside of the support arm 16, the limit button 14 can be moved out of the base plate 1, allowing the support arm 16 to rotate to the outside of the base plate 1. It should be noted that there are four rollers 205, evenly distributed at the four corners of the bottom of the base plate 1. There are six support arms 16, evenly distributed at the bottom of the base plate 1. By pulling the limiting pin 12 upward to extend the first limiting block 303 and the second limiting block 13, the handle 302 can be used to rotate the door panel 304 around the rotating rod 301, facilitating maintenance personnel to enter the protective basket 5. Then, by resetting the limiting pin 12, the door panel 304 can be closed. After the worker enters the protective basket 5, pressing down on the basket 5 and its bottom causes the fixing post 201 to move downward and press down on the elastic pad 203. At this time, the limiting cone 204 will... By lowering the arm to make close contact with the ground, the base plate 1 and the protective basket 5 can be stably limited. The extended support arm 16 can stably support the base plate 1 and the protective basket 5. By simultaneously controlling the extension ends of the four electric telescopic rods 4 to extend upwards, the protective basket 5 and its interior can be lifted. No large power vehicle is required to provide power, and the protective basket 5 and the base plate 1 can be stably supported by gravity. This further reduces the size and facilitates the maintenance of power lines in confined spaces. By using external hoisting equipment and external connecting ropes to connect with the lifting ring 7, it is convenient to hoist the base plate 1 and the protective basket 5 together for long-distance transportation or for higher lifting. This solves the problem that some existing lifting structures for high-altitude power maintenance rely on large power vehicles for power. When power maintenance is needed in narrow alleys, passages between buildings in residential areas, and urban streets, these lifting devices are difficult to access. Even if they can be accessed, space limitations may prevent the working arm from being extended to a suitable position for power maintenance work, which limits their use.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
