Railway transportation and highway transportation are two kinds of main means of transportation in existing land transportation system.Wherein, articulated car
It is the common haulage vehicle of one of railway transportation, bearing capacity is strong, can greatly improve the efficiency of railway transportation；It is public
The defeated main form using semitrailer of road transport, semitrailer can easily realize installation and removal between truck, and transport is very
It is convenient.
With the development of transport service, inevitably to be docked between Transportation modes.Existing railway transportation with
Docking between highway transportation is the efficiency ten by will be loaded on rolling stock after the cargo unloading on highway semitrailer
Divide low.And since articulated car is merely able to transferring containers, also need to be loaded into after unloading cargo from semitrailer
It can be placed on articulated car and be transported after in container, the quite time-consuming effort of whole process.
To improve the efficiency of railway transportation and highway transportation in docking, piggyback service and highway semitrailer are transported
Combining is that a great development direction of current railway transportation in order to adapt to develop railroad well car occurs, can be transported
Container and energy conveying semi-trailer, still, how by semitrailer, fixation is urgent problem on depressed center car.
Railroad well car includes end flat and the central depression that is formed between end flat from the side, energy
Enough it is suitable for the transport of containers of various specifications.Central fovea can be directly placed it in the shorter container of transportation lengths
In concave portion, the both ends of container can be individually positioned on end flat in transportation lengths longer container.Semitrailer
Length be less than railroad well car central depression, semitrailer can be directly placed on to the central fovea of railroad well car
In concave portion, still, after semitrailer is put into railroad well car, since the height of semitrailer tire is higher than depressed center car center
Recessed portion so that the towing pin of semitrailer is located at the top on depressed center car both ends floor, thus using being set on the floor of both ends
The mode for setting the semi-mounted traction seat in conventional road transport will not be able to effectively fix the towing pin of semitrailer；This
Outside, traditional semi-mounted traction seat be carried out by artificial pull joystick lock and unlock operation, and in railway transportation its
Operating space is limited, and inconvenience carries out manual operation；In addition, if directly the traction base of semitrailer in highway transportation is arranged in concave bottom
Transport of the depressed center car to container will be will affect on the both ends floor of flatcar, so that the Loading conditions of depressed center car are limited.
In order to overcome the drawbacks described above under the prior art, the purpose of the present invention is to provide one kind to be used for railroad well car
The locking device and railroad well car of conveying semi-trailer, locking device of the invention are remaining the original function of depressed center car
Under the premise of, the Loading conditions of depressed center car have been expanded, have enabled depressed center car directly to implement to transport to semitrailer, to keep away
Exempt from the loading and unloading when railway transportation and highway transportation are docked to cargo, greatly improves the efficiency of transport.
The contents of the present invention are described below in conjunction with attached drawing is detailed, so that those skilled in the art can be more
The detailed understanding contents of the present invention.
