Railway transportation vehicle unit of multi-specification large-tonnage precast girders

Abstract

The invention discloses a railway transportation vehicle unit of multi-specification large-tonnage precast girders. The railway transportation vehicle unit comprises a head vehicle and a tail vehicle, wherein the head vehicle adopts the same main-body structure as the tail vehicle; a plurality of fixing positions for bridge-girder supporting devices are arranged on the head vehicle, and a plurality of fixing positions for bridge-girder supporting devices are arranged on the tail vehicle; the transportation of multi-specification precast girders is realized by moving the fixing positions of the bridge-girder supporting devices on the head vehicle and the tail vehicle. The railway transportation vehicle unit disclosed by the invention can transport precast girders of 16m, 24m, 32m, and the like, which are close to length specifications, and has multiple functions; the head vehicle and the tail vehicle adopt steel-floor structures, positioning holes are formed in steel floors, the steel floors are made by a mold and have interchangeability, and the positions of steering wheel holders and the positions of the bridge-girder supporting devices are convenient to change; major configurations of the head vehicle, major configurations of the tail vehicle, and major configurations of a middle railway wagon adopt a convention mature technology, and are high in reliability; when the railway transportation vehicle unit does not transport girders, any of the head vehicle, the tail vehicle and the middle random vehicle can be used as a common flat vehicle, so that the application of the railway transportation vehicle unit is flexible.

Description

technical field [0001] The invention belongs to the field of railway vehicles and road and bridge construction, and relates to a multi-standard and large-tonnage prefabricated beam railway transport train set. Background technique [0002] At present, the domestic railway vehicles used to transport large-tonnage prefabricated beams are only suitable for transporting prefabricated beams with a span of 32 meters, and cannot transport prefabricated beams of other sizes. The function is single. With the rapid development of the world economy, more and more enterprises The requirements for the diversification and multi-function of rail vehicles are getting higher and higher, and the types and spans of prefabricated beams are also more and more diversified. How to realize the railway transportation of multi-standard and large-tonnage prefabricated beams needs to be solved urgently.

Problems solved by technology

[0002] At present, the domestic railway vehicles used to transport large-tonnage prefabricated beams are only suitable for transporting prefabricated beams with a span of 32 meters, and cannot transport prefabricated beams of other sizes. The function is single. With the rapid development of the world economy, more and more enterprises The requirements for the diversification and multi-functionality of rail vehicles are getting higher and higher, and the types and spans of prefabricated beams are also increasing. How to realize the railway transportation of multi-specification and large-tonnage prefabricated beams is an urgent problem to be solved.

[0003] Existing railway vehicles for transporting prefabricated beams cannot transport prefabricated beams of other specifications. For example, there is no suitable transportation device when transporting 16-meter prefabricated beams and 24-meter prefabricated beams. When transporting prefabricated beams other than 32 meters Difficulty, inefficiency of precast girder transport caused by limitations of precast girder rail transport vehicles
