Problems solved by technology
The inventor has found that at present, the wheel chocks used by the railway piggyback vehicles are fixed on the railway piggyback vehicles. Due to the wide variety of freight semi-trailers, different types of freight semi-trailers have different lengths, different wheelbases, and different wheel diameters. The railway piggyback transport vehicle can only meet the use requirements of specific types of freight semi-trailers, which greatly reduces the applicability of the railway piggyback transport vehicle

Embodiment 2
[0052] This example discloses a rail carrier back carrier, an active wheel block of the rail carrier back transport vehicle according to Embodiment 1, and a set of iron carrier back transport vehicles are installed on both sides of the rail carrier back transport vehicle. With active gear unit, the guide of the rail carrier back transport vehicle is adjacent to the inner side of the rail carrier back transport vehicle.
[0053] When the rail carrier back transport vehicle is used, the semi-trailer is transported to the rail carrier back transport vehicle. The staff lifts the handle, and the handle is rotated by the handle. At this time, the first pulley and the second slider are along the conduit circumference surface The axis rotates, the latter is disengaged from the positioning hole, and the block is moved in the direction of the guide axis. At this time, the first pulley and the second pulley slide in the direction of the conduit axis, the block moves to the set position, bloc...

The invention relates to a movable wheel chock device for a railway piggyback transport vehicle and a railway piggyback transport vehicle, comprising: a pedal, a conduit is fixed on one side of the pedal; a pad: connected to at least two rotating mechanisms through a connecting piece, and the rotating mechanism It includes a first rotating shaft fixedly connected to one end of the connecting piece, the other end of the first rotating shaft is fixed with a connecting plate, the first rotating shaft is rotatably connected to the first pulley, the connecting plate is fixed with a second rotating shaft, and the second rotating shaft is rotatably connected to the second pulley , the conduit is arranged between the first pulley and the second pulley and is in contact with the first pulley and the second pulley through an arc surface, the bottom of the pad is provided with a pin, and the pin can be inserted into the positioning hole provided by the pedal. The movable wheel chock of the present invention High flexibility and strong applicability.
Description
Technical field [0001] The present invention relates to a technical field of railway piggyback truck, in particular to a railroad-wheel piggyback truck with stop means piggyback truck and rail. Background technique [0002] Rail piggyback transport is a combined road and rail transportation, freight container or trailer open directly on to the piggyback or lifting truck for transport to reach the destination to open or hanging down from the car to the ground station field. The inventors have found that, at present, the railway wheel piggyback truck with fixed block railway piggyback truck, freight trailer since a wide range of different types of freight trailer different lengths, different wheelbase, different wheel diameter, the current piggyback rail vehicles can only meet the needs of specific types of freight semi-trailer, which greatly reduces the applicability of the railway piggyback truck. Inventive content [0003] Object of the present invention is to overcome the disa...
