Description

Flatbed for track maintenance operation Technical Field The utility model belongs to the technical field of flat cars, and particularly relates to a flat car for track maintenance operation. Background The flat car for track maintenance operation is a special vehicle for transporting maintenance equipment, tools and materials in the field of track traffic such as railways, subways and the like, mainly runs on a track line and provides material transportation support for operations such as line maintenance, equipment replacement, daily inspection and the like. At present, the platform lorry for track maintenance operation on the market mainly comprises a bearing platform and a moving structure, wherein the bearing platform is used for storing articles, and then the device is enabled to move on a track through the moving mechanism. However, in practical use, a commercial flatbed for track maintenance operation has the following drawbacks: Firstly, the bearing platform area of the existing flat car is fixed, when a large amount of articles (such as long rail pieces and multiple mechanical devices) are required to be transported, the bearing area cannot be adjusted and expanded through the structure of the existing flat car, a plurality of car bodies can be rigidly assembled together (such as in a bolt connection or in a hinge connection) through special tools, the operation is complex and time-consuming, secondly, after the plurality of car bodies are assembled, a connecting gap exists between the adjacent platforms, and the connecting position of the car bodies can form a stepped structure (namely, a height difference or an uneven surface), and the stepped structure can influence the storage of the articles. Therefore, it is necessary to provide a pallet truck for track maintenance work.
