Abstract

The invention discloses a large-opening-degree sliding plug door system for a high-speed freight transportation motor train unit. The large-opening-degree sliding plug door system comprises a bearing drive mechanism, a gantry, a door sash, an external operating mechanism and a lower swing arm assembly. The bearing drive mechanism is fixedly connected with the door sash through the gantry and is located above the door sash, the external operating mechanism is installed on the side face of the door sash and used for controlling the door sash to be opened from the outer side of a vehicle body, and the lower swing arm assembly is arranged below the inner wall of the door sash and used for supporting the door sash for opening or closing. The large-opening-degree sliding plug door system is simple in structure and convenient to assemble, is provided with the lower swing arm assembly below the inner wall of the door sash and used for supporting the door sash for opening or closing, improve the stability of the door sash and can achieve transportation of cargoes of 1500 mm*2600 mm, the bearing drive mechanism greatly saves the space in the vehicle, a rodless air cylinder is adopted for driving, and the large-opening-degree sliding plug door system is high in security coefficient, small in later-period maintenance work amount, stable in operation, simple in structure and easy to achieve and has a good application prospect.

Description

technical field [0001] The invention relates to a large-opening sliding door system for a high-speed freight train set, belonging to the technical field of the train set door system. Background technique [0002] At present, there is no sliding door system for freight trains on the market. The door leaf opening of the existing high-speed passenger sports car sliding door system is small, generally around 800mm, which can only be used during passenger transportation and cannot be realized. For the transportation of large single cargo, limited by the opening of the door leaf, it is impossible to load and unload a large amount of cargo per unit time, which greatly reduces the working efficiency of the high-speed cargo sports car group. Moreover, the principle of pneumatic or electric is used to realize the opening and closing movement of the door , poor safety and reliability. Contents of the invention [0003] The purpose of the present invention is to solve the problem tha...
