[0010] The bottom of the counterweight box is provided with a fixing hole, and a fixing bolt for fixing the counterweight block in the counterweight box is arranged in the fixing hole.

[0011] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0012] By setting a counterweight box under the working platform and installing movable counterweight blocks inside the counterweight box to adjust the bottom center of gravity, the overall stability of the working platform is enhanced. By setting a slide rail, the upper working platform can be moved easily, making it convenient for operators to carry out maintenance operations on the transformer. This utility model has a simple and reasonable structure and effectively increases the stability of the working platform. Attached Figure Description

[0018] like Figures 1-4 As shown, a high-altitude work safety platform for substation maintenance includes a work platform 3 with a counterweight box 1 at the bottom. The work platform 3 and the counterweight box 1 are connected by a connecting rod 8. The counterweight box 1 has a sliding counterweight block 10 inside. The counterweight box 1 has openings at both ends for the counterweight block 10 to slide out. The top of the counterweight block 10 has a sliding groove 11. A vertically upward limiting rod 16 is slidably connected inside the sliding groove 11. Mounting frames 14 are symmetrically arranged at the four corners of the bottom of the counterweight box 1. The mounting frames 14 are equipped with wheels 15. The connecting rod 8 is equipped with a handle 9. The work platform 3 is equipped with a ladder 2 for operators to use. The ladder 2 allows operators to climb onto the work platform 3 for maintenance operations. Since the bottom center of gravity may be unstable when the operator moves above the work platform 3, another worker can adjust the bottom center of gravity by moving the counterweight block 10 below, thereby enhancing the overall stability.

[0019] The top of the connecting rod 8 is provided with slide rods 5 extending to both sides, the top of the slide rods 5 is provided with slide rails 6, the bottom of the operation platform 3 is provided with sliding blocks 7 in the slide rails 6, the operation platform 3 slides above the slide rails 6 through the sliding blocks 7, sometimes the upper part of the transformer substation needs to be overhauled, so the operation platform 3 needs to be moved as a whole to the outside, therefore, the slide rails 6 are arranged to move the operation platform 3.

[0020] The top of the operation platform 3 is provided with guardrails 4, the side of the counterweight box 1 and the bottom of the ladder 2 are correspondingly provided with positioning holes 12, positioning bolts 13 for fixing the ladder 2 and the operation platform 3 are arranged in the positioning holes 12, the ladder 2 is fixed with the counterweight box 1, so that the operation platform 3 after moving is fixed.

[0021] Both ends of the counterweight block 10 are provided with handles (not shown in the figure) for the operator to pull, the handles are arranged to facilitate the operator below to move the counterweight block 10.

[0022] The guardrails 4 are provided with openings for the operator to go up and down, the openings are provided with guardrail doors (not shown in the figure) which can be closed, the guardrail doors are arranged to further protect the maintenance operator above the operation platform 3.

[0023] The bottom of the counterweight box 1 is provided with a fixing hole, the fixing hole is arranged with a fixing bolt 17 for fixing the counterweight block 10 in the counterweight box 1, as shown in the figure, the counterweight block 10 is fixed in the counterweight box, so that the counterweight block 10 is prevented from extending out of the counterweight box 1 during movement. Figure 4
