Disclosure of Invention
The invention aims to provide a freight transportation motor train unit train body structure which comprises a train roof, an underframe, end walls and side walls, wherein the underframe comprises a floor and side beams, the train body side walls are composed of block side walls, large-opening-degree train doors are arranged among the block side walls to meet the requirement that goods are quickly lifted up and down in a passenger station, and reinforcing structures are arranged on the periphery of the large-opening-degree train doors to meet the requirements of train body strength and train body mode.
In order to achieve the purpose, the invention provides a freight transportation motor train unit train body structure, which comprises a train roof, a bottom frame, end walls and side walls, wherein the bottom frame comprises a floor and side beams, and is characterized in that: the side wall is the piecemeal side wall, the piecemeal side wall is formed by vertical aluminium alloy and aluminium alloy door stand fixed connection, sets up the big opening gate between two piecemeal side walls, and the reinforcing beam on the welding door between door stand upside and roof boundary beam, reinforcing beam and chassis boundary beam form gate frame rack structure jointly on side wall door stand, the door, and the door corresponds regional chassis boundary beam below fixed connection door stiffening beam. The large-opening doorway structure ensures the requirements of the strength and the mode of the vehicle body through the doorway frame type structure and the reinforcement beam under the door.
The under-door stiffening beam is used as a cross beam of the under-vehicle equipment hoisting structure and is integrated with the under-vehicle equipment hoisting structure. The reinforcing beam under the door plays a role in reinforcing the strength of the lower side of the doorway and also plays a role in conveniently installing equipment under the vehicle as part of a hoisting mechanism of the equipment under the vehicle.
The freight transportation EMUs body structure still include the reinforcement door foot, reinforcement door angle is connected between door stand and chassis boundary beam, reinforcement door angle door mouth side is the arc, prevents this position stress concentration, increases door angle intensity.
The door corner area of the reinforcing beam is in arc transition, the outline of the reinforcing beam is consistent with that of the side wall, on one hand, the strength of the door corner is increased, and on the other hand, the door corner area is connected with the side wall and the rear surface is in a plane.
The car body chassis comprises a coupler seat and two vertical plates, wherein the coupler seat is located at the end part of the car body chassis, the two vertical plates are located on the front side of the coupler seat, a flat plate is fixedly connected to the upper side of an area enclosed by the coupler seat and the two vertical plates on the front side of the coupler seat, and the flat plate and the two vertical plates form an inverted U-shaped structure. As no windshield is arranged between the freight transportation motor train unit bodies, dust, rain, snow and the like are prevented from falling in.
Compared with the existing passenger transport motor train unit, the requirement that goods are quickly transported up and down in a passenger transport station is met by arranging the large-opening-degree vehicle door between the block side walls, the frame structure formed by the door upright post, the door upper reinforcing beam and the underframe boundary beam is adopted, and the reinforcing beam is arranged below the door boundary beam, so that the strength of the large-opening-degree door vehicle body and the vehicle body mode meet the requirement.
