Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment transportation, in particular to an anti-dumping device for a high-voltage circuit breaker cabinet trolley. Background Art

[0002] With the increasing number of power grid substations, 10kV circuit breakers in substations basically use KYN28 type cabinets. When the circuit breaker in this cabinet is transferred from the cold standby position to the maintenance position, it is necessary to use a trolley to pull the circuit breaker from the test position to the trolley, and then pull the trolley away from the cabinet to realize the transfer and maintenance of the circuit breaker.

[0003] However, the existing trolley does not have an anti-dumping function. When the circuit breaker is placed on the trolley and the circuit breaker is to be switched from cold standby to overhaul, or from overhaul position to cold standby, the trolley does not move in a straight line during the pulling process due to work needs or uneven ground conditions. Sometimes it moves in an S shape, sometimes in a Z shape. Different operators have different operations and encounter different situations when pulling the trolley, which results in different trolley movement speeds and movement trajectories. In addition, the uneven ground and the surrounding environment may cause the circuit breaker trolley to topple over, thereby causing damage to personnel and equipment.

[0004] The weight of the circuit breaker is about 150 kg, and the weight of the trolley is about 20 kg. It is very laborious to pull the circuit breaker from the inside of the switch cabinet to the trolley or to push the circuit breaker from the trolley to the inside of the switch cabinet.

[0031] Working principle:

[0032] When the circuit breaker needs to be moved, the vehicle body 1 is moved to the front side of the switch cabinet, the switch cabinet is fitted between the vehicle body 1, and the height of the lifting platform 5 is adjusted by the lifting mechanism to make the height of the lifting platform 5 level with the height of the circuit breaker. The circuit breaker is pulled to the upper end of the evenly arranged rotating wheels 6, and the two fastening knobs are tightened so that the clamping strips 7 clamp the evenly arranged rotating wheels 6. In the process of pushing the vehicle body 1, if an uneven road surface is encountered, the two anti-tilt plates 3 on the front side wall of the vehicle body 1 can effectively bear the force, thereby preventing the trolley from tipping over and improving the driving stability.
