Road and railway transportation wagon group and marshalling method thereof

Abstract

The invention discloses a road and railway transportation wagon group and a marshalling method thereof, and relates to the technical field of railway wagons. The road and railway transportation wagongroup comprises at least two road and railway semitrailers, at least one joint bogie and two end bogies; each joint bogie is located between every two adjacent road and railway semitrailers and is connected with the road and railway semitrailers on the two sides of the joint bogie through wagon group coupling devices; the end bogies are located at two ends of a wagon group; one end of each end bogie is coupled with the corresponding road and railway semitrailer through an end coupling device, and the other end is coupled with a railway locomotive or a railway wagon through a coupler bufferingdevice. Through implementation of the technical scheme, the technical problems that invalid dead weight in existing road and railway transportation wagon groups is relatively heavy, vehicle end clearances are relatively large and train longitudinal force transfer is non-uniform can be solved effectively, quick marshalling coupling of the wagon group can be realized, the invalid dead weight of thewagon group can be reduced, the vehicle end clearance can be reduced, the train longitudinal force transfer can be uniform, and the wagon group performance and the transportation economical efficiencycan be improved effectively.

Description

technical field [0001] The invention relates to the technical field of railway wagons, in particular to a road-rail dual-purpose transport wagon set and a marshalling method thereof. Background technique [0002] Multimodal transport can give full play to the overall advantages and combined efficiency of various modes of transport. Through the rapid reverse transportation of transport units, the number of loading and unloading of goods in different modes of transport can be reduced, and seamless "door-to-door" services can be provided for cargo owners. Representative In the direction of comprehensive transportation development. The existing road-railway trucks include two special bogies and a road-railway semi-trailer. To marshal with semi-trailers, it is necessary to connect the coupler buffer devices of adjacent special bogies to each other to form a transport car group. [0003] However, the inventors of the present application found that the above-mentioned prior art h...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems of the existing road-rail dual-purpose transport car group with heavy dead weight, large gaps between vehicles, the existing special bogies that can only be marshalled in one direction and the longitudinal force transmission in the car group is uneven, the present invention The purpose is to provide a road-rail dual-purpose transport vehicle group. The first purpose is to simplify the internal connection device of the road-rail dual-purpose vehicle group, reduce the ineffective weight of the vehicle group, reduce the gap between vehicles, increase the number of vehicle formations, and improve transportation economy. The second purpose is to effectively realize the joint marshalling of the special bogie in the car group in any two directions with the semi-trailer for road and rail, improve the speed of marshalling, and facilitate the use and management of the transport car group; the third purpose is to effectively ensure the The height of the connecting centers inside the rail dual-purpose transport vehicles is consistent, the longitudinal force of the train is transmitted evenly, and there will be no additional resistance in the horizontal direction of the vehicle group, which can effectively avoid multiple gradient transfers in the height of the longitudinal force of the train and reduce the attenuation of the longitudinal force. Further reduce transport energy loss to improve transportation economy, and the train has good operating performance; the fourth purpose is to effectively improve the formation and connection efficiency of road-rail dual-purpose transport vehicles, and meet the nods of railway operating conditions for road-rail dual-purpose transport vehicles , head shaking and roll degrees of freedom require
