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 t

Embodiment 1

[0056] Embodiment one is basically as figure 1As shown: the present embodiment provides a road-rail dual-purpose transport vehicle group, which includes at least two road-rail dual-purpose semi-trailers 1, at least one articulated bogie 2 and two end bogies 3, the road-rail dual-purpose semi-trailer The number of trailers 1 is N and they are arranged sequentially along their traveling direction. N road-rail dual-purpose semi-trailers 1 are grouped into a group of railway transportation through two end bogies 3 and (N-1) intermediate joint bogies 2. For unit trains, the number N of road-rail dual-purpose semi-trailers 1 in the transport car group can be increased or decreased according to the organization of the supply of goods. The combination of road-rail dual-purpose semi-trailers 1 is convenient and flexible, and it is convenient and flexible to meet the needs of the railway transportation of goods. needs, it is beneficial to improve transportation performance, reduce trans...

Embodiment 2

[0061] Embodiment 2 is basically the same as Embodiment 1, the difference is that: as a preference of Embodiment 1, the train set connecting plate 221 provided in this embodiment is specifically a dumbbell-shaped symmetrical flat plate structure, and a fixed mounting seat 23 is arranged in the middle , the car group connecting plate 221 is fixed on the knuckle bogie 2 frame through the fixed mounting seat 23, to ensure the stability of the center support at the two ends of the car group connecting plate 221; and the car group at both ends of the car group connecting plate 221 Mounting holes are all arranged on the connecting section; and the upper end surface and the lower end surface of the connecting hanger 222 of the train group are provided with the corresponding round pin 223 holes of the train group connecting the hanging plate 221 end mounting holes, so that the train The car group connecting hanging sections at both ends of the group connecting hanging plate 221 are res...

Embodiment 3

[0067]The third embodiment is basically the same as the second embodiment, the difference is: please refer to Figure 7 to Figure 10 As shown, the end bogie 3 provided in this embodiment includes an end welding frame 31, specifically, the end connecting device 32 includes an end connecting plate 321, an end connecting seat 322 and an end connecting round pin 323 , the end connecting plate 321 includes a fixed section and an end connecting section, the end connecting plate 321 is connected with the end welding frame 31 through the fixing section, and the end connecting seat 322 is located on the road-rail dual-purpose semi-trailer of the transport vehicle group 1. In the front end beam 111 at the end, one end of the end bogie 3 is inserted into the end connection seat 322 through the end connection section, and passes through the end connection plate through the end connection round pin 323 from bottom to top 321 and the end connect the hanger seat 322 upper end connection seat...

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...
