Double-deck container flat car

Abstract

The invention discloses a double-deck container flat car, which comprises a car coupler buffer device, a semi-trailer bearing seat, a car body, a bogie, a braking device and a container fixing and locking mechanism, wherein the car body comprises a large underframe and a traction device; the cross section and the vertical section of the large underframe are of an all-steel welding concave structure, and an upper port of the concave structure forms a well-mouth shaped structure of the large underframe; the large underframe comprises side walls and a concave bottom; underframe bearing seats are symmetrically arranged in the middle and at two ends of the large underframe, and the bearing seats are connected with the side walls and the concave bottom. The concave bottom well type structure furthest utilizes line limits and designs a car bottom bearing surface to an allowable minimum value; the bottom of the whole car, the traction device and an upside beam form the concave bottom structure; the container fixing and locking mechanism and corresponding observation ports can carry double-deck multi-sized containers conveniently and safely; and the flat car has light self weight and large loading and can simultaneously meet the transportation mode of multi-size containers and greatly enhance the capacity of railway transportation in multimodal transportation.

Description

technical field [0001] The invention belongs to the field of railway transport equipment manufacturing, and in particular relates to a railway freight flat car, in particular to a railway freight flat car for loading double-layer containers or road semi-trailers. Background technique [0002] In order to achieve sustainable development of my country's railways, in addition to focusing on speed-up and heavy-load cargo transportation, it will develop in the direction of high value-added container transportation. In some developed countries, the volume of railway container transport has accounted for more than 1 / 4 of the total railway freight volume, while my country's railway container transport accounts for about 2.3% of the railway freight volume. With the deepening of my country's reform and opening up and the further development of the economy, railway transportation is gradually becoming in line with international standards. The iron standard 5t and 10t containers will b...

AI Technical Summary

Problems solved by technology

[0005] Existing railway container vehicles are usually of flat structure and can only carry single-layer containers; some can carry double-layer containers, but cannot carry road semi-trailers. Double-layer container vehicles suitable for COFC and TOFC transportation methods have not yet been seen.
