Description
Technical Field
The invention relates to a side wall structure of a rail vehicle, and belongs to the field of rail vehicle bodies.
Background
The mechanical room is a space for installing and integrating various vehicle-mounted equipment on the locomotive, and therefore, the mechanical room needs to be sealed to prevent rain and snow from entering. The mechanical room is a closed space consisting of an underframe, a cab partition wall, a rear end wall, left and right side walls and a top cover, wherein the underframe, the cab partition wall, the rear end wall, the left and right side walls are welded together, and the top cover is connected with other parts through bolts.
The traditional locomotive side wall is a fixed welding structure formed by assembling and welding a stand column, a cross beam, an upper chord beam, a side wall upper structure and a skin together, and when the side wall and an underframe of the structure are assembled and welded, the condition that welding cannot be performed between the side wall stand column and the underframe edge beam due to shielding of an equipment installation framework above the underframe is often caused. Moreover, the fixed sidewall structure is inconvenient for installation, maintenance and repair of equipment in the mechanical room.
The utility model discloses a chinese utility model patent CN201120008034.7 discloses a locomotive side wall, the main points of this patent lie in all being divided into two blocks that the length is equivalent to the side wall of every side of locomotive, wherein, a side wall is fixed side wall, another side wall is the activity side wall, the gyro wheel is installed to activity side wall bottom, when the activity side wall is pushed this one side of fixed side wall, form two side wall structures with fixed side wall, at this moment the activity side wall is in the open mode, when the activity side wall is pushed back the opening side, just be in the enclosed condition between locomotive machinery. However, such a movable sidewall has two obvious limitations: firstly, the bearing capacity of the movable side wall is very weak, and the movable side wall can hardly bear the longitudinal force of the locomotive. Secondly, the movable side wall is originally designed to facilitate the installation, maintenance and overhaul of equipment between machines, but because the width of the side wall can be only half of that of the fixed side wall, the equipment between machines on the side of the fixed side wall is still inconvenient to install, maintain and overhaul.
When the conventional means meets the condition that welding cannot be performed between the side wall stand column and the side beam of the bottom frame, the conventional means is used for excavating the fixed skin of a welding region to form a hole, then welding is performed, and after the welding is finished, the hole in the fixed skin is plugged.
