Problems solved by technology

The existing docking between railway transportation and road transportation is to unload the goods on the road semi-trailer and then load them on the railway vehicle, which is very inefficient
And because the railway flat car can only transport containers, after the goods are unloaded from the semi-trailer, they need to be loaded into the container before they can be placed on the railway flat car for transportation. The whole process is very time-consuming and labor-intensive.

Abstract

The invention provides a locking device used for a transporting semitrailer of a railway depressed center flat car and the railway depressed center flat car. The locking device comprises a rotary armwhich is arranged on end floor of the depressed center flat car, wherein the first end of the rotary arm is equipped with a locking part which is connected with a traction pin of the semitrailer; thelocking part is a groove formed in the first end of the rotary arm, and the groove is provided with an opening end; a locking mechanism for closing or opening the opening end is arranged at the opening end; the middle part of the rotary arm is equipped with a rotary shaft mounting hole perpendicular to the rotary arm; a rotary shaft is arranged in the rotary shaft mounting hole; the rotary arm canrotate around the rotary shaft in the horizontal direction; the lower end of the rotary shaft is connected to the end floor through a first drive part; and the first drive part can drive the rotary arm to move in the vertical direction. The locking device can realize directly fixing the semitrailer onto the railway depressed center flat car, so that loading and unloading of goods during butt-joint are avoided, and transporting efficiency is greatly improved.

Description

technical field [0001] The invention relates to the manufacturing technology of rail vehicle components, in particular to a locking device for a semi-trailer transported by a railway concave-bottomed flat car and a railway concave-bottomed flat car. Background technique [0002] In the existing land transportation system, railway transportation and road transportation are two main modes of transportation. Among them, the railway flat car is a commonly used transport vehicle in railway transportation. It has a strong carrying capacity and can greatly improve the efficiency of railway transportation; road transportation mainly adopts the form of semi-trailer, which can be conveniently connected with trucks It can be installed and disassembled, and the transportation is very convenient. [0003] With the development of the transportation industry, it is inevitable that there will be docking between various transportation methods. The docking between existing railway transport...
