[0002] The 10kV switchgear circuit breaker maintenance platform is one of the important tools for maintaining and repairing 10kV vacuum circuit breakers. It is responsible for carrying the heavy vacuum circuit breaker during daily cleaning and maintenance work, and it is also a platform for troubleshooting vacuum circuit breakers.

[0003] The existing technology has the following problems:

[0004] 1. The trolley is fixed, posing a safety hazard of personal injury during transport. The existing maintenance platform is 0.9m high, and the vacuum circuit breaker weighs 150kg, requiring four people to move it to the ground. During transport, the circuit breaker may tilt and slip due to varying forces, potentially injuring the circuit breaker itself and the personnel involved, thus posing a safety hazard.

[0005] 2. The trolley is bulky and difficult to carry, and the existing emergency repair process is complex, requiring a large amount of manpower and slowing down the repair speed. Currently, each site only stores one 10kV circuit breaker maintenance trolley. When a fault occurs, replacing the circuit breaker requires four steps and at least five people. Step 1: One person uses the maintenance platform to pull the circuit breaker out of the cabinet; Step 2: One person secures the maintenance platform, and four people move the faulty 10kV circuit breaker to the ground; Step 3: One person continues to secure the maintenance platform, and four people move the new circuit breaker from the ground to the maintenance platform; Step 4: Push the new circuit breaker into the compartment.

[0006] 3. The application scope of the trolley is narrow, and it is currently only suitable for the maintenance of 10KV switchgear circuit breakers.

[0007] Therefore, it is necessary to provide an electric maintenance platform vehicle for circuit breakers to solve the above problems. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The described embodiments are some embodiments of this application, but not all embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1 , Figure 2 , Figure 3 An embodiment of the present invention provides an electric maintenance platform vehicle for circuit breakers, comprising: a movable chassis, a lifting mechanism, a worktable, and a platform vehicle handrail. The lifting mechanism is mounted on the movable chassis, and the drive end of the lifting mechanism is fixedly connected to the bottom of the worktable. The lifting mechanism drives the worktable to rise and fall. The platform vehicle handrail is mounted on the movable chassis.

[0031] The workbench includes a base plate 12, a fixed baffle 2, and a movable baffle 1. The base plate 12 can be 1200 mm long and 700 mm wide. The fixed baffle 2 is fixedly installed on two opposite sides of the base plate. The two opposite fixed baffles are symmetrically provided with two or more grooves 3. The base plate 12 is provided with two parallel guide rails 14. Correspondingly, the movable baffle 1 is provided with grooves that match the guide rails. The movable baffle 1 can move along the guide rails 14 and can be fixed by the grooves 3 on the fixed baffle 2. When the grooves are provided at both ends of the fixed baffle, the movable baffle can be fixed at both ends.

[0032] In practical use, movable baffles can be installed in appropriate locations according to the specifications of the circuit breaker to prevent the circuit breaker from falling and causing personal injury, thus making the application of the trolley more widespread.

[0033] The lifting mechanism is a scissor hydraulic lifting structure, specifically including a folding lifting rod 4, a drive motor 6, a hydraulic rod 7, an oil tank 5, an oil pump, oil pipes, and valves. The hydraulic rod 7 is hinged at both ends and installed in the middle of the crossbeam of the folding lifting rod 4. The oil pump is connected to the oil tank and the hydraulic rod through oil pipes, and the drive motor is electrically connected to the oil pump.

[0034] In actual use, the drive motor drives the oil pump to do work on the hydraulic rod, and the extension and retraction of the hydraulic rod is controlled by the valve to realize the lifting and lowering of the worktable. When the worktable is lowered to the lowest point, it can be folded and stored.

[0035] In addition, the platform truck's handrail is equipped with a momentary lifting button 10, which can be used to control the lifting of the worktable.

[0036] The movable chassis is equipped with casters 8, and the casters 8 are equipped with wheel locking devices 9, which can facilitate the movement and fixation of the platform vehicle.

[0037] An embodiment of the present invention provides a method for using an electric maintenance platform vehicle for circuit breakers.

[0038] During emergency repairs, the electric maintenance platform vehicle for circuit breakers can be transported from an adjacent station to the faulty station. The electric maintenance platform vehicle for circuit breakers can be equipped with a movable baffle to work in conjunction with the 10KV circuit breaker. When a new circuit breaker is installed, it is ensured to be fixed securely and without any hidden dangers.

[0039] When a fault occurs, the electric circuit breaker maintenance platform truck is used in conjunction with the existing traditional 10kV switchgear maintenance platform. Replacing the circuit breaker requires two steps and two people. Step 1: One person uses the old maintenance platform to pull the faulty circuit breaker out of the cabinet; simultaneously, another person uses the new platform to pull the new circuit breaker out of the traditional maintenance platform. Step 2: Raise the electric circuit breaker maintenance platform truck and push the new circuit breaker into the cabinet.
