[0026] The utility model solves the problem that when the top platform is raised, it will be affected by wind and vibration and cause shaking, which reduces the stability of the platform and cannot ensure the safety of the operation. In addition, when the workers working at height need tools, they need to go up and down frequently, which increases the risk of high-altitude operation, causes work interruption, increases maintenance time, and reduces work efficiency. Figure 1-Figure 3 The shown embodiment is a lifting platform for repairing electrical equipment in a substation, comprising a base plate 1, a top plate 3 being provided on the top surface of the base plate 1, two first fixing frames 11 being symmetrically fixedly connected to one side of the top surface of the base plate 1, the first fixing frame 11 being rotatably connected to a first support rod 2, a second support rod 21 being rotatably connected to the middle part of the first support rod 2, the first support rod 2 and the second support rod 21 being cross-arranged, a second fixing frame 22 being fixedly connected to one end of the top of the second support rod 21, and the top end of the second fixing frame 22 being fixedly connected to one side of the bottom surface of the top plate 3; when repairing electrical equipment at high places, a lifting platform is required for repair.

[0027] In the present utility model, a first limit plate 51 and a second limit plate 52 are fixedly connected to both sides of the top surface of the base plate 1, and a screw rod 53 is rotatably connected between the first limit plate 51 and the second limit plate 52. A motor 5 is fixedly connected to the middle of the top surface of the base plate 1, and the rotating shaft of the motor 5 passes through the first limit plate 51 and is fixedly connected to the end of the screw rod 53. A wire hole is provided in the middle of the connecting rod 23 at the bottom, and the screw rod 53 is matched with the wire hole for connection; when lifting, the motor 5 is turned on, and the motor 5 rotates to drive the screw rod 53 to rotate, and the rotation of the screw rod 53 drives the connecting rod 23 at the bottom to move, and the movement of the connecting rod 23 drives the sliding frame 24 at the bottom to move, thereby completing the lifting work. The first limit plate 51 and the second limit plate 52 play a limiting role. There is a base at the bottom of the motor 5, and the motor 5 is mounted on the top surface of the base plate 1 through the base.

[0028] It should be noted that two strip rods 25 are fixedly connected to the top surface of the bottom plate 1 and the bottom surface of the top plate 3 on the side away from the first fixed frame 11, and the first support rod 2 and the second support rod 21 are rotatably connected to the end away from the first fixed frame 11. The outer periphery of the connecting rod 23 is fixedly connected to a sliding frame 24, and the two sliding frames 24 are respectively slidably connected to the corresponding strip rods 25; during the movement of the connecting rod 23, one end of the first support rod 2 and the second support rod 21 rotates on the connecting rod 23, and at the same time, the first support rod 2 and the second support rod 21 complete the folding and unfolding actions, thereby completing the lifting work.

[0029] When in use, the maintenance personnel stands on the top surface of the top plate 3 and rotates the first support rod 2 and the second support rod 21. The ends of the first support rod 2 and the second support rod 21 rotate on the first fixing frame 11 and the second fixing frame 22 respectively. The first support rod 2 and the second support rod 21 are unfolded to lift the top plate 3. The first support rod 2 and the second support rod 21 are adjusted according to the height of the electrical equipment.

[0030] Through the cooperation of the first support rod 2 and the second support rod 21, the maintenance personnel can be quickly lifted to the required height. The maintenance personnel can be easily lifted to the required height, reducing physical labor such as climbing, reducing labor intensity, and improving work efficiency.

[0031] The cross structure of the first support rod 2 and the second support rod 21 has excellent stability and load-bearing capacity, ensuring the safety of maintenance personnel during operation.

[0032] In the present utility model, an opening 31 is provided on the side of the top plate 3 away from the first fixing frame 11, and a tool box 41 is inserted into the opening 31. An electric cylinder 42 is fixedly connected to the top surface of the bottom plate 1 away from the first fixing frame 11, and the top end of the piston rod of the electric cylinder 42 is fixedly connected to the bottom surface of the support plate 4; when transferring tools or supporting the top plate 3, the electric cylinder 42 is opened, and the electric cylinder 42 drives the support plate 4 to move through the piston rod, and the movement of the support plate 4 drives the tool box 41 to move. When the tool box 41 is inserted into the opening 31, the maintenance personnel above can take the tools in the tool box 41.

[0033] It should be noted that a rotating plate 33 is rotatably connected inside the opening 31, and guardrails 32 are fixedly connected around the top surface of the top plate 3; the guardrails 32 can prevent maintenance personnel from falling from the top plate 3, protecting the safety of maintenance personnel, and the rotating plate 33 can open and close the opening 31.

[0034] It should also be noted that a support plate 4 is provided on the side of the bottom surface of the top plate 3 away from the first fixed frame 11, the top surface of the support plate 4 is movably connected to the bottom surface of the top plate 3, and a tool box 41 is fixedly connected to the top surface of the support plate 4; when the top plate 3 is raised to the specified height, the support plate 4 is moved upward, and the movement of the support plate 4 drives the tool box 41 to move upward, and the support plate 4 contacts the bottom surface of the top plate 3 to support the top plate 3.

[0035] When the top plate 3 is raised, its center of gravity is relatively high and it will be affected by external factors such as wind and vibration and will shake. The setting of the support plate 4 can provide more support points for the top plate 3, enhance the load-bearing capacity of the platform, thereby effectively reducing the shaking of the top plate 3, improving the stability and safety of the top plate 3, and ensuring the safety of the operation.

[0036] The support plate 4 can be raised and lowered synchronously when the first support rod 2 and the second support rod 21 are raised and lowered, ensuring that the platform moves smoothly in the vertical direction, avoiding tilting, and ensuring the accuracy and precision of the operation.

[0037] Furthermore, when maintenance personnel at a high place need tools, the support plate 4 moves downward, and the maintenance personnel below places the required tools into the tool box 41, and the support plate 4 then raises the tool box 41 to the position of the top plate 3. Maintenance personnel do not need to frequently go up and down the top plate 3 to retrieve tools, which saves maintenance time and improves work efficiency.

[0038] When maintenance personnel are working at height, frequently raising and lowering the top plate 3 will increase the safety risk of falling. The cooperation between the tool box 41 and the components can obtain the required tools without interrupting work, reducing the risk of working at height and maintaining the continuity and efficiency of work.

[0039] When maintenance personnel are working at height, ground personnel can pass tools or materials through the support plate 4, which improves collaboration efficiency and avoids the trouble of searching for tools or materials during the operation.

[0040] In the present invention, the guardrail 32 is provided with a gate-type fence that can be opened and closed, which is a mature technology in the prior art and will not be described in detail here.

[0041] It should be noted that rollers 12 are provided at the four corners of the bottom surface of the base plate 1; the equipment can be moved to the electrical maintenance location by the rollers 12. There is a brake structure on the rollers 12. The brake structure is a mature technology in the prior art. It is not shown in the figure and will not be repeated here. The rollers 12 can use an electric structure, and the specific structure is not limited.
