DETAILED DESCRIPTION

[0021] The following will fully and clearly describe the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. The embodiment described in this scheme is only one embodiment, not all embodiments. All embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0022] See also Figure 1-Figure 3 A maintenance platform for operation and maintenance of substation equipment comprises a base frame 1, characterized in that a maintenance platform 2 is fixedly installed on the top of the base frame 1, a guide rail 3 is fixedly connected to the inside of the base frame 1, and a slide 4 is slidably connected to the outer surface of the guide rail 3 through a telescopic mechanism, and a fixed frame 11 is fixedly connected to the end of the slide 4 away from the base frame 1, and a frame shaft 12 is fixedly connected to the outer surface of the fixed frame 11, and a buckle plate 13 is movably connected to the outer surface of the frame shaft 12 through an elastic limiting mechanism.

[0023] During operation, a maintenance platform for substation equipment operation and maintenance can extend and retract the fixed frame 11 to different distances under the action of the sliding telescopic mechanism, so that the buckle plate 13 is buckled on the grid frame bars at different distances, and the bottom frame 1 stabilizes the maintenance platform 2.

[0024] The telescopic mechanism also includes a screw rod 5 rotatably connected to the inside of the bottom frame 1, a knob 6 arranged at the bottom of the screw rod 5, an L-shaped shift frame 7 is threadedly sleeved on the outer surface of the screw rod 5, and the outer surface of the shift frame 7 is slidably connected to the rear side of the inside of the bottom frame 1, and the outer surface of the shift frame 7 is fixedly penetrated with left and right lower plate shafts 8, and the left and right lower plate shafts 8 are symmetrically penetrated on both sides of the screw rod 5.

[0025] The outer surface of each lower plate shaft 8 is rotatably connected with a connecting plate 9 , and two left and right upper plate shafts 10 are fixedly penetrated through the inner side of the slide 4 , and the outer surface of each upper plate shaft 10 is rotatably connected with the top of the connecting plate 9 .

[0026] Through the above technical scheme, the shift frame 7 will cause the top and bottom of the connecting plate 9 to rotate respectively, the upper plate shaft 10 and the lower plate shaft 8 during the movement process. The outer surface of the lower plate shaft 8 is rotatably connected to the connecting plate 9, and the upper plate shaft 10 is fixedly penetrated on the inner side of the slide 4, and the outer surface of the upper plate shaft 10 is rotatably connected to the top of the connecting plate 9.

[0027] Through the above technical solution, the connecting plate 9 can push and pull the slide 4 through the upper plate shaft 10 during the deflection process, so that it slides along the guide rail 3.

[0028] Specifically, the elastic limiting mechanism includes a fixing rod 14 fixedly connected to the outer surface of the fixing frame 11 , the fixing rod 14 is connected to the upper end of the strong spring 15 , and the bottom end of the strong spring 15 is movably arranged on the inner side of the buckle plate 13 .

[0029] Through the above technical solution, the end of the buckle plate 13 is designed to be concave, and under the pulling of the strong spring 15, the buckle head at the end of the buckle plate 13 can be buckled on the power grid support relatively stably.

[0030] Specifically, a handle 16 is fixedly connected to the outer surface of the pinch plate 13 , and a limiting frame 17 is fixedly connected to the outer surface of the fixing frame 11 .

[0031] Through the above technical solution, the limiting frame 17 is used in conjunction with the buckle plate 13, and has the effect of phase limiting the buckle of the power grid support, thereby reducing the deviation and shaking of the buckle plate 13 after buckling.

[0032] When the maintenance platform is in use, the positions of the two sets of fixing frames 11 can be adjusted through the telescopic mechanism according to the spacing of the upper rack bars of the power grid support. That is, the knob 6 can be rotated to drive the screw rod 5 to rotate. The screw rod 5 will drive the shift frame 7 to move up and down along the inner side of the bottom frame 1 during the rotation process, and drive the connecting plate 9 to deflect. During this period, the top and bottom of the connecting plate 9 will rotate along the upper plate axis 10 and the lower plate axis 8 respectively, and the connecting plate 9 will push and pull the slide 4 through the upper plate axis 10 during the deflection process, so that the slide 4 slides laterally along the guide rail 3, and the fixing frame 11 at the end of the slide 4 changes its position accordingly. Afterwards, under the elastic pulling of the strong spring 15, the buckle plate 13 rotates clockwise along the frame axis 12 until the buckle head of the buckle plate 13 is stably buckled on the frame of the power grid support. The bars are on the grid support, and the relative limiting of the limit frame 17 on the grid support bars can indirectly stabilize the bottom frame 1 and the inspection platform 2 relatively stably, so that the operation and maintenance equipment can be inspected and maintained on the inspection platform 2. When disassembling, it is only necessary to push the handle 16 upward to make the buckle plate 13 rotate counterclockwise along the frame axis 12. During this period, the buckle plate 13 will stretch the strong spring 15 until the buckle head of the buckle plate 13 is no longer buckled on the grid support bar, so that the entire inspection platform can be quickly removed. In general, this improvement scheme effectively solves the problems of insufficient stability and potential safety hazards in the operation and maintenance of traditional high-altitude power grid racks, improves the stability, safety and efficiency of operations through technical means, and provides reliable tools and support for the maintenance and maintenance of power grid equipment.

[0033] The above embodiments are used to illustrate the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
