Problems solved by technology

[0004] However, the coupler used as the traditional car coupling device is often large in size and complex in structure, so the distance between the cars is increased, which can neither meet the coupling of railway freight cars in the articulated bogie marshalling method, nor meet the outline of road vehicles. size requirements
As a result, the traditional coupler cannot be used as a coupling device between road and rail vehicles

Embodiment Construction

[0024] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but it does not constitute a limitation of the present invention, and is only used as an example. At the same time, the advantages of the present invention will become clearer and easier to understand through the description.

[0025] Such as Figures 1 to 3 As shown, one end of the movable coupler 1 is welded on the bottom of one end of the road and railway dual-purpose carriage, and the other end protrudes outward; the fixed coupler 2 is integrally welded on the bottom of the other end of the carriage. Two adjacent road and railway dual-purpose carriages are connected with the fixed coupler 2 through the movable coupler 1 . In the fixed coupler 2, there is an internal space for horizontally accommodating the other end of the movable coupler 1. The other end of the movable coupler 1 is provided with a first through hole 1.1 longitudinally, and t...

Abstract

The invention discloses a coupling device for a rail-road vehicle. The coupling device comprises a fixed vehicle hook and a movable vehicle hook. Two adjacent carriages are connected through the movable vehicle hook and the fixed vehicle hook. One end of the movable vehicle hook is fixed to the bottom of one carriage, and the other end of the movable vehicle hook stretches out outwards. The fixed vehicle hook is fixed to the bottom of the other end of the other carriage and is provided with internal space for transversely containing the other end of the movable vehicle hook. A first through hole is longitudinally formed in the other end of the movable vehicle hook, and a second through hole corresponding to the first through hole is longitudinally formed in the fixed vehicle hook. After the other end of the movable vehicle hook is inserted into the fixed vehicle hook, a connecting pin penetrates the first through hole and is hinged to the second through hole. A connecting rod assembly is arranged at the bottom of the connecting pin and controls the connecting pin to be inserted into or disengaged from the first through hole and the second through hole. The coupling device for the rail-road vehicle can meet the requirement for coupling of the rail-road vehicle and is easy to operate and safe and reliable in coupling.

Description

technical field [0001] The invention relates to a railway vehicle coupling device, in particular to a road and railway dual-purpose vehicle coupling device. Background technique [0002] The railway technology policy proposes to run various forms of freight trains, to carry out extended intermodal services, to promote centralized transportation and "door-to-door" transportation, and to increase the on-time arrival rate of goods. The implementation of railway freight organization reform will guide the development of railway freight in the direction of "door-to-door" logistics in the future. As the main way to achieve "door-to-door" transportation, the joint operation of road and railway cleverly integrates road and rail transportation to speed up the delivery of goods. [0003] Road-rail combined transport is a combination of road and rail transportation, that is, the use of road and rail dual-purpose vehicles for transportation. This kind of road and rail dual-purpose vehi...
