Description

Technical Field

[0001] The invention relates to the technical field of locomotive and vehicle maintenance, in particular to a railway locomotive and vehicle maintenance operation platform. Background Art

[0002] After a railway locomotive has been in use for a period of time, in order to ensure the running safety of the locomotive, it will undergo daily inspection and maintenance. When inspecting and maintaining the locomotive, preventive regular inspections, parts replacement repairs, and specialized and centralized repairs of major components are usually adopted.

[0003] For example, a railway locomotive vehicle maintenance platform with publication number CN219567491U is used to inspect and repair the locomotive through a detachable lifting support device and a working platform. The position of the locomotive on the lifting plate can be positioned under the action of an extension rail and a limit rod. At the same time, the installed lifting latch rod and abutment plate facilitate the movement of the working platform.

[0004] When the above device is in use, when inspecting the bottom of the vehicle, the staff needs to lie flat on the work platform to inspect the bottom of the vehicle, and the staff lying flat needs to raise their hands for inspection. If the hands are raised for a long time, the staff's arms will feel sore and swollen, and they need to rest before continuing the inspection. At the same time, after the inspection of a certain part of the bottom of the vehicle is completed, the staff needs to leave the work platform, adjust the work platform from under the work platform, and then lie on the work platform to inspect the locomotive. This operation is more troublesome and the adjustment position can only be judged by visual inspection, which is inconvenient for the staff to adjust to an accurate position. When the locomotive is inspected, its wheels are not locked. When it is inspected in a place with a certain slope, the locomotive is prone to slide under its own gravity, which will cause certain dangers to the safety of the staff who are repairing.
