[0042] By providing a placement groove 11 on the same side of the base 10 and the extension frame, the auxiliary device is installed on the outside of the lightning arrester 90 through the placement groove 11, which has good stability and is convenient for inspection and maintenance of the lightning arrester.

[0043] Example 2:

[0044] In this embodiment, see Figure 1-5 The extension frame includes a fixed frame 20 and a telescopic frame. The fixed frame 20 is fixedly mounted on the base 10, and the telescopic frame is movably mounted on the fixed frame 20. A lifting drive is connected to the telescopic frame to drive the telescopic frame up and down. The provision of the telescopic frame facilitates the extension of the extension frame. For example, when moving the auxiliary device, the telescopic frame retracts to lower the height for easier movement. When the lightning arrester 90 needs to be inspected and repaired, the telescopic frame extends to facilitate climbing height for maintenance.

[0045] For details, see Figure 1 、 3 The base 10 is a frame structure with a small top and a large bottom. The upper end of the base 10 is fixedly connected to the extension frame, and the lower end is equipped with casters 12. The provision of casters 12 facilitates the movement of the auxiliary device. Specifically, the casters 12 are casters with brakes. When a position limit is required, the brake is applied to limit the position, and when the position is required to move, the brake is released.

[0046] In this embodiment, the telescopic frame includes a first movable frame 30, which is mounted on the outside of the fixed frame 20. The lifting drive device includes a first reduction motor 60 and a first screw 61. The first reduction motor 60 is mounted on the base 10 or the lower end of the fixed frame 20. One end of the first screw 61 is fixedly connected to the output shaft of the first reduction motor 60, and the other end is rotatably connected to the upper end of the fixed frame 20. A first nut seat 31 is mounted on the first movable frame 30, and the first screw 61 is screwed to the first nut seat 31. The first reduction motor 60 drives the first screw 61 to rotate, thereby driving the first movable frame 30 to rise and fall.

[0047] In this embodiment, the first movable frame 30 is a C-shaped frame. A crossbar is also provided on the first movable frame 30 , which not only enhances the structural strength but also facilitates climbing.

[0048] In this embodiment, two sets of first reduction motors 60 and first screw rods 61 are symmetrically installed.

[0049] Example 3:

[0050] Based on Example 2, see Figure 1-3 The telescopic frame further includes a second movable frame 40 , which is sleeved on the outside of the first movable frame 30 .

[0051] Specifically, the second movable frame 40 includes a lower groove plate 41, a guide rod 42 and an upper groove plate 43, and the guide rods 42 are respectively installed at the four corners between the lower groove plate 41 and the upper groove plate 43; the upper end of the first movable frame 30 is equipped with two fixed slides 32 at upper and lower intervals corresponding to each guide rod 42, and each guide rod 42 is slidably connected to the two fixed slides 32 at the corresponding position.

[0052] Furthermore, the lifting drive device also includes a second reduction motor 70 and a second screw 71. The second reduction motor 70 is installed at the lower end of the first movable frame 30. One end of the second screw 71 is fixedly connected to the output shaft of the second reduction motor 70, and the other end is rotatably connected to the top of the first movable frame 30. A second nut seat 47 is installed on the lower groove plate 41, and the second nut seat 47 is threadedly engaged with the second screw 71.

[0053] The second reduction motor 70 drives the second screw 71 to rotate, thereby driving the second movable frame 40 to move up and down.

[0054] In this embodiment, the lower groove plate 41 and the upper groove plate 43 are C-shaped structures.

[0055] Furthermore, in order to facilitate climbing on the second movable frame 40 , pedals 44 are slidably and adjustably mounted on two adjacent guide rods 42 on the second movable frame 40 .

[0056] Specifically, when the second movable frame 40 moves down and is recovered, the pedal 44 slides on 42 and is stacked on one side of the upper groove plate 43; when the second movable frame 40 moves up and extends, the pedal 44 falls naturally. After the personnel climbs onto the first movable frame 30, the pedal 44 is fixed on the guide rod 42 in sequence according to the required height limit.

[0057] In one of the schemes, see Figure 1 Slide sleeves 45 are mounted on both ends of the pedal 44. Thumb screws 46 are screwed onto the slide sleeves 45. When the thumb screws 46 abut against the guide rod 42, the pedal 44 and the guide rod 42 are fixed in place. Before retracting the second movable frame 40, the thumb screws 46 at both ends of the pedal 44 are loosened in sequence from top to bottom. During maintenance, after the second movable frame 40 is extended, the pedal 44 is fixed to the guide rod 42 by tightening the thumb screws 46 from bottom to top.

[0058] Example 4:

The rope 82 is sleeved on the fixed pulley 81. One end of the rope 82 is mounted with the hook 83. By manually pulling the other end of the rope 82, the hook 83 is lifted, making it easier to provide tools and materials to the top of the lightning arrester 90 through the hook 83.

[0064] Furthermore, a hoisting device 84 is also installed on the base 10, and the other end of the rope 82 is wound around the hoisting device 84. The hoisting device 84 can be electric or manual. In this embodiment, the electric hoisting device 84 is preferred.

[0065] The working principle or action process of the utility model is as follows:

[0066] When used for maintenance, the auxiliary device is moved by the casters 12 on the base 10. When it is moved to the side of the lightning arrester 90, the placement groove 11 is aligned with the lightning arrester 90, and then the auxiliary device is pushed. The auxiliary device is installed to the outside of the lightning arrester 90 through the placement groove 11, and then the brake on the caster 12 is locked.

[0067] The first reduction motor 60 is activated to rotate the first screw 61, driving the first movable frame 30 upward. The second reduction motor 70 is then activated to rotate the second screw 71, driving the second movable frame 40 upward. After the second movable frame 40 is extended, a person climbs onto the first movable frame 30 and secures the pedals 44 to the guide rods 42 in sequence, tightening the thumb screws 46 from bottom to top.

[0068] After the personnel climb onto the second movable frame 40 through the pedal 44, they install the clamp 51 to hold the lightning arrester 90 through bolts, and connect the clamp 51 to the second movable frame 40 through the connecting piece 52, wherein the connecting piece 52 is distributed on the left and the right.

[0069] When tools and materials need to be provided to the top of the arrester 90 during maintenance, the tools and materials are fixed with a sling and hooked on the hook 83, and the hoisting device 84 is started to lift the tools and materials.
