DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figure 1 and Figure 2 As shown, an electric power equipment maintenance device for a substation includes four moving wheels 1, the upper ends of the four moving wheels 1 are commonly fixedly connected to a support assembly 2, the upper end of the support assembly 2 is fixedly connected to a support assembly 2 4, the front end of the support assembly 2 4 is fixedly connected to an escalator 3, the upper end of the support assembly 2 4 is slidably connected to a matching assembly 6, and the upper front side of the matching assembly 6 is fixedly connected to a control end 5.

[0018] During the specific implementation process, the operator is required to push the device to the required maintenance location, and then climb to the inner cavity of support component 2 4 through the escalator 3, and control the start of the internal power source of support component 2 through the control end 5, and then support component 12 will lift support component 2 4 and move it upward. When support component 12 lifts support component 2 4 to a certain height, the components inside support component 12 can be used to limit the ground, thereby avoiding instability at the bottom when the device is too high. Furthermore, if the height of support component 2 4 lifted by support component 12 is not enough to support the maintenance personnel for maintenance, the operator can also control the matching component 6 through the control end 5 to lift it a second time, so that the maintenance personnel can adjust the maintenance height more flexibly, thereby improving the maintenance efficiency.

[0019] It should be further explained that the control terminal 5 mentioned above is a mature control technology in the prior art. In this solution, the controllable function thereof is utilized, and its structure and principle are not further elaborated.

[0020] For further information, please refer to Figure 3As shown, the support component 2 includes a base 21, and a slide groove 22 is opened on the left side of the front and rear sides of the base 21. The inner cavity of the slide groove 22 is slidably connected with an anti-slip component 23. The right side of the base 21 is rotatably connected to two rotating rods 24, and the sides of the two rotating rods 24 that are close to each other are rotatably connected to a rotating column 25. A hydraulic rod 1 28 is fixedly connected to the middle part of the outer surface of the rotating column 1 25, and the middle parts of the two rotating rods 1 24 are both rotatably connected to the connecting column 26, and the outer surfaces of the two connecting columns 26 are fixedly connected to the side close to each other with a rotating rod 27, and the upper ends of the two rotating rods 27 are rotatably connected to the rotating rod 4 211, and the middle parts of the two rotating rods 4 211 are both rotatably connected to the rotating rod 3 29, and the upper parts of the two rotating rods 3 29 are rotatably connected to the support seat 210 together, and the left parts of the front and rear sides of the support seat 210 are provided with a sliding groove 213, and the upper parts of the side close to each other of the two rotating rods 4 211 are rotatably connected to the rotating column 212 together, and the middle part of the outer surface of the rotating column 212 is fixedly connected to the upper part of the hydraulic rod 1 28, and the bottoms of the sides away from each other of the two rotating rods 27 are fixedly connected to sliding rods, and the two sliding rods are slidably connected to the inner surfaces of the two corresponding sliding grooves 1 22.

[0021] In the further implementation process, when the maintenance personnel control the hydraulic rod 1 28 to extend or retract through the control end 5, the support seat 210 can be raised. In the process of the support seat 210 rising, the rotation rod 3 29 and the rotation rod 4 211 cooperate to cross-lift. Further, in the process of the rotation rod 3 29 and the rotation rod 4 211 being cross-lifted, the rotation rod 2 27 and the rotation rod 1 24 that are rotatably connected to the bottom of the rotation rod 4 211 will be driven to cross, so that the support seat 210 can further raise the support component 2 4, so that the maintenance personnel can achieve multi-layer operations while approaching the target, thereby improving the overall utilization of the working space and the efficiency of collaboration.

[0022] It should be further explained that the above-mentioned hydraulic rod 28 is a very mature technical means in the prior art. In this solution, its function of raising or lowering is utilized, and its structure and principle will not be elaborated again.

[0023] Further, such as Figure 4 As shown, the anti-skid component 23 includes a U-shaped sliding plate 231, and the front and rear sides of the U-shaped sliding plate 231 are slidably connected to the inner surfaces of the two sliding grooves 22. A spring 233 is fixedly connected to the middle of the U-shaped sliding plate 231, and the upper end of the spring 233 is fixedly connected to the middle of the bottom end of the base 21. The left and right sides of the U-shaped sliding plate 231 are fixedly connected to two fixed plates 232.

[0024] Furthermore, during the implementation process, when the bottom of the rotating rod 27 slides a certain distance in the inner cavity of the slide groove 22, it will squeeze the slopes on the front and rear sides of the U-shaped sliding plate 231, so that the U-shaped sliding plate 231 drives the fixed plates 232 on the left and right sides to descend, thereby increasing the overall contact area between the limit assembly 23 and the ground, avoiding the bottom from shaking easily when the maintenance personnel are performing maintenance.

[0025] Furthermore, by increasing the contact area between the limit assembly 23 and the ground, the load can be effectively dispersed and the shaking or tilting caused by uneven pressure or external interference can be reduced, so that maintenance personnel can be more stable during maintenance.

[0026] For further information, please refer to Figure 5 and Figure 6 As shown, the support component 2 4 includes a shell 41, and four slide grooves 3 42 are opened on the inner surface of the shell 41. A hydraulic rod 2 43 is fixedly connected to the bottom of the front side of the inner surface of the shell 41, and a rack 44 is fixedly connected to the rear of the hydraulic rod 2 43. A gear 1 46 is meshed on the outer surface of the rack 44, and a connecting rod 47 is fixedly connected to the inner surface of the gear 1 46. U-shaped fixing plates 45 penetrate the left and right sides of the outer surface of the connecting rod 47, and the left and right ends of the connecting rod 47 are fixedly connected to the gear 2 48. Two matching columns 1 49 are fixedly connected to the middle of the bottom wall of the inner surface of the shell 41. The matching component 6 includes a matching plate 61, and the outer surface of the matching plate 61 Four sliding bars 62 are fixedly connected to the surface, and a fixed plate 2 63 is commonly fixedly connected to the bottom ends of the four sliding bars 62. A sliding guardrail 65 is fixedly connected to the upper end of the fixed plate 2 63. Two matching columns 2 64 are fixedly connected to the bottom end of the matching plate 61. The outer surfaces of the two matching columns 2 64 are slidingly connected to the inner surfaces of the two corresponding matching columns 1 49. The outer front surfaces of the two matching columns 2 64 are matched with two corresponding gears 2 48. The four sliding bars 62 are arranged in a ring array, and the four sliding grooves 3 42 are arranged in a ring array. The four sliding bars 62 are slidingly connected to the four corresponding sliding grooves 3 42.

[0027] Furthermore, during the implementation process, when the support seat 210 lifts the shell 41 to a certain extent, the operator can also control the hydraulic rod 2 43 to extend and retract through the control end 5, so that when the hydraulic rod 2 43 is extended or retracted, the rack 44 can be driven to cooperate with the gear 1 46, so that when the gear 1 46 rotates, the gear 2 48 fixedly connected at the front and rear ends can be driven to rotate. When the gear 2 48 rotates, it will drive the matching column 2 64 to rise or fall, so that the matching plate 61 fixedly connected to the upper end of the matching column 2 64 can rise or fall through the four sliding bars 62. Further, when the fixed plate 2 63 rises or falls, the mobile guardrail 65 and the control end 5 will rise or fall with the matching plate 61, so as to protect the maintenance personnel in real time and prevent the maintenance personnel from slipping and falling. It is further necessary to explain that the hydraulic rod 1 43 is a very mature technical means in the prior art. In this solution, its function of raising or lowering is utilized, and its structure and principle are not further described. It should be further explained that the inner surface of the first matching column 49 is completely penetrated so as to accommodate the outer surface of the second matching column 64. Furthermore, a groove is provided in the middle of the two matching columns 49, and one side of the groove is close to the front end of the housing 41. Furthermore, a plurality of mating half rings are fixedly connected to the outer surface of the mating column 1 49 , so that the two gears 48 can mesh with each other while rotating, so that the mating column 2 64 can drive the mating plate 61 to rise or fall.

[0028] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
