Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of maintenance tools, in particular to a vehicle roof climbing ladder. Background Art
[0002] As we all know, the electric current that high-speed trains rely on for operation is transmitted through the high-speed railway contact network on the top of the locomotive. When there is heavy snow, the snow on the top of the high-speed train will freeze under the influence of cold air, which will cause poor contact between the train pantograph and the contact network. When there is strong wind, the strong wind will blow foreign objects onto the contact network, causing the high-speed train to stop operating, requiring operators to climb up to inspect the contact network.
[0003] Most of the existing technologies use hanging ladders or herringbone ladders. By placing the hanging ladder or herringbone ladder on one side of the high-speed train and fixing it to be stable, the operator can climb up to inspect the top of the high-speed train. Patent document number CN210164418U discloses a special high-speed rail fault handling ladder, including a folding ladder body that can lean against the side wall of the high-speed rail, an extension bracket connected to the upper part of the folding ladder body and can be overlapped on the top of the high-speed rail, and a soft belt with one end detachably connected to the lower part of the folding ladder and the other end provided with a hook. The folding ladder is placed on the side of the high-speed train by abutting the extension bracket with the top of the high-speed train carriage. However, the stability of the folding ladder placed on the side of the high-speed train is still poor, and there is still a large safety hazard when the operator stands on the top of the folding ladder.
