[0028] See also Figure 1-5 The utility model provides a technical solution: a lifting device for transformer maintenance, comprising two support rods 1, the surface of the support rods 1 is provided with an adjustment mechanism for adapting to various terrains, and the adjustment mechanism comprises:

[0029] The telescopic unit 2 is mounted on the surface of the support rod 1. The telescopic unit 2 includes a slot 21 provided at the bottom of the support rod 1.

A plurality of teeth 24 are fixedly connected to the surface of the slide plate 23 at equal intervals.

[0030] The extension unit 3 is installed in the inner cavity of the slot 21 and is used for the sliding of the slide bar 22. The slide bar 22 is connected by sliding in the inner cavity of the slot 21. The top of the slide bar 22 is fixedly connected to a slide plate 23. The surface of the slide plate 23 is equidistantly fixedly connected to a plurality of teeth 24. The extended end of the rotating shaft 311 is fixedly connected to a gear 312. The surface of the gear 312 is meshed with the teeth 24. This solves the problem that the escalator used during maintenance will fall to one side when facing an unhardened road surface, which brings resistance to maintenance, increases maintenance time, affects local electricity consumption, and affects people's livelihood. It achieves the balance of the two sides by lengthening the side with softer ground, and it can also be freely extended and retracted. According to the actual situation, the slide bar 22 is used as a support foot to lengthen the height for adjustment.

[0031] In this embodiment, the stretching unit 3 includes:

[0032] The transmission assembly 31 is installed in the inner cavity of the card slot 21 for sliding the slide bar 22. The transmission assembly 31 includes a rotating shaft 311 rotatably connected to the surface of the support rod 1. One end of the rotating shaft 311 penetrates the surface of the support rod 1 and extends. The extended end of the rotating shaft 311 is fixedly connected to a gear 312. The surface of the gear 312 meshes with the teeth 24.

[0033] The limiting assembly 32 is installed in the inner cavity of the slot 21 and is used to limit the position of the gear 312 .

[0034] In this embodiment, the limiting assembly 32 includes a trapezoidal groove 321 opened on the surface of the support rod 1, and the interior of the trapezoidal groove 321 is rotatably connected to a rotating rod 322, and the rotating rod 322 is fixedly connected to a baffle 323 on the surface of one end in the slot 21, and a plurality of limiting blocks 324 are fixedly connected to the surface of the baffle 323.

[0035] In this embodiment, a spring 4 is fixedly connected to the surface of the baffle 323 , and two ends of the spring 4 are fixedly connected to the inner cavity of the slot 21 and the surface of the baffle 323 , respectively.

[0036] In this embodiment, the other end of the rotating shaft 311 is fixedly connected to a handle 5 , and the handle 5 is round. A pointing block 6 is installed on the surface of the round handle 5 .

[0037] In this embodiment, connecting rods 7 are equidistantly fixedly connected to the opposite sides of the two support rods 1, and trapezoidal blocks 8 are rotatably connected to the opposite sides of the two support rods 1, and the trapezoidal blocks 8 are located below the connecting rods 7. By fixing connecting rods 7 equidistantly on the opposite sides of the two support rods 1, and trapezoidal blocks 8 are rotatably connected to the opposite sides of the two support rods 1, and the trapezoidal blocks 8 are located below the connecting rods 7, the problem that the ground is slippery after rain and the ground cannot withstand the pressure of the ladder during maintenance work, causing the ladder to sink, resulting in the ladder being not long enough or unstable, is solved. The wide ground of the trapezoidal blocks 8 is used to increase the force-bearing area to withstand the pressure of people on the escalator surface, better adapt to harsh conditions, and the trapezoidal blocks 8 can be rotated in a small range and adjusted according to the angle of the ladder to facilitate maintenance. At the same time, the contents not described in detail in this specification belong to the prior art known to technical personnel in this field.

[0038] During operation, when encountering an uneven ground caused by collapse on one side, the rotating rod 322 is pressed by hand, and the rotating rod 322 rotates in the inner cavity of the trapezoidal groove 321 to drive the baffle plate 323 to rotate, and the baffle plate 323 rotates to squeeze the spring 4 to deform, and the baffle plate 323 drives the limit block 324 to rotate, and the limit block 324 follows the baffle plate 323 to rotate until it is no longer engaged with the surface of the gear 312, and then the handle 5 is turned to one side, and the handle 5 rotates to drive the rotating shaft 311 to rotate, and the rotating shaft 311 drives the gear 312 to rotate, and the gear 312 rotates through the teeth 24 engaged with the surface to drive the slide plate 23 to slide in the inner cavity of the slot 21, and the sliding of the slide plate 23 drives the sliding rod 22 to slide, and the sliding rod 22 slides. 22 slides to the outside and contacts the ground. The sliding of the slide bar 22 makes this side continue to penetrate into the ground. After reaching a balance with the other side, stop turning the handle 5 and stop pressing the rotating rod 322. The spring 4 loses its extrusion and its restoring force drives the baffle plate 323 to rotate. The baffle plate 323 drives the limit block 324 to rotate so that the limit block 324 engages with the surface of the size to complete the limit. Then the staff can use heavy pressure to keep both sides stable before using them. After the above steps, when both sides sink, the side with the largest area of ​​the trapezoidal block 8 is in contact with the ground through heavy pressure. At this time, the force area is increased, which can prevent further sinking and help the staff complete the emergency repair smoothly.
