Description
Technical field
The locking attachment device of the utility model a kind of fixed railway freight-car and highway semitrailer is related to a kind of when progress
The fixation locking attachment device of highway railway combined transport, railway freight-car and semitrailer, belongs to railway freight-car apparatus field and logistics transportation skill
Art field.
Background technology
In recent years, Traditional Transportation industry in China's is undergoing a change Traditional Transportation pattern to multimodal transport transition and upgrade
Change.Wherein, railway carries a kind of unlucky defeated important way for having become rail-road multimodal transport on the back, and workflow is filled from goods yard
Origin railway station is arrived after loading object, loading goods train semitrailer is transported to destination railway station, and long-distance fortune is completed by railway
It is defeated, semitrailer is unloaded from railway freight-car after arriving at railway station, link on-highway tractor allocates dispatching.
In order to ensure security and stability of the semitrailer in transport, dedicated fixed locking device can be set and connected admittedly
It is fixed.Application number CN201610782494.2, country origin China, Publication No. CN106428076A, publication date 2017.02.22.
1, the device can be accomplished by bevel gear transmission lengthwise position adjust, therefore can solve even if length over ends of body difference according to
Railway freight-car can be so put into be fixed, but the apparatus structure is complicated and structure is thin, it is complicated for operation；2, do not consider due to
Railway jolts when transport, can cause the semitrailer to have vertical power；3 at the same do not consider due to transport when railway bend, meeting
Generating centrifugal force causes closed-type semitrailer to deviate；If 4, the railway freight-car needs to carry out Container Transport, the height of the device
Hinder the position that container is put into lock；5, using traction pin connection semitrailer and railway freight-car, towing pin can be caused compared with
Big abrasion.
According to the GB1589 of latest edition《Automobile, trailer and truck combination contour dimension, axle load and quality limit value》Regulation,
The length limit of semitrailer is set as 13.75 meters；45 forty equivalent unit 40 length are 13.716 meters.To which semitrailer is in railway goods
" loaded " position and " loaded " position of 45 forty equivalent unit 40s on railway freight-car on vehicle is almost the same.Semitrailer is packed into railway freight-car
And when under severe duty, babinet lower plane and 45 forty equivalent unit 40 locking device loading ends there is only the difference in height of 14mm,
Currently on the market there are no by 45 forty equivalent unit 40 locking devices come the device of locking highway semitrailer.
Utility model content
The utility model is intended to provide a kind of fixation railway freight-car simple in structure, rigid is high and highway carry on the back it is unlucky defeated
The locking attachment device of semitrailer.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of fixed railway freight-car and highway half
