The invention relates to the technical field of rail vehicle construction, in particular to an overhead line system operation ladder trolley for a railway vehicle. The overhead line system operation ladder trolley comprises an operation platform, a climbing device, a spring device, adjusting devices and a vehicle box, wherein the vehicle box is arranged on a track in a sliding mode, the operationplatform, and the climbing device and the spring device are arranged in the vehicle box; the spring device comprises a compression spring, wherein the bottom end of the compression spring is connectedwith the bottom of the vehicle box in an abutting mode, the top end of the compression spring abuts against the bottom end of the operation platform, the stretching length of the compression spring can be adjusted by the adjusting devices, the climbing device can stretch and contract along with the stretching and retracting of the compression spring, the top end of the operation platform is connected with the bottom end of the operation platform, the bottom end of the vehicle box is connected with the bottom of the vehicle box, and a cover plate capable of being opened and closed is arrangedat the top of the vehicle box. The overhead line system operation ladder trolley for the railway vehicle can adapt to overhead line systems with different heights, the operation efficiency is improved, the space occupied by the whole ladder trolley is reduced, and the ladder trolley is more convenient to place, carry and transfer.
Description
technical field [0001] The invention relates to the technical field of rail vehicle construction, in particular to a catenary work ladder car for rail vehicles. Background technique [0002] Catenary operating ladder trolley is an indispensable and important equipment for the construction and maintenance of electrified railways. The height of the catenary is different in different railways, and sometimes there will be ups and downs and curved turning sections, so the height safety of the catenary work ladder car is different. The current catenary operation ladder car mainly has the following problems: [0003] (1) The height of the traditional ladder car is not easy to adjust. When the clearance of the tunnel is different, it is necessary to equip the ladder car with different heights, which not only reduces the operating efficiency, but also increases the operating cost; [0004] (2) The traditional ladder car has a narrow chassis and a high body, and it often runs and wo...
