Passenger room underframe internal installation structure easy to dismount for urban rail vehicle

Abstract

The invention discloses a passenger room underframe internal installation structure easy to dismount for an urban rail vehicle. The passenger room underframe internal installation structure easy to dismount for the urban rail vehicle comprises a floor installation base, cold-proof materials, aluminum honeycomb floors, floor cloth and floor pressing bars. The internal installation structure further comprises a profile installation base. The section of the profile installation base is in an L shape. The profile installation base comprises a high step and a low step and is installed at the end of a vehicle body underframe. An end electrical cabinet is fixed to the upper end face of the high step of the profile installation base. The aluminum honeycomb floor at the end is in lap joint with the low step of the profile installation base through the stepped lap joint surface of the aluminum honeycomb floor, and the other aluminum honeycomb floors are in lap joint in sequence through the stepped lap joint surfaces of the aluminum honeycomb floors. The section of each floor pressing bar is in an inverted J shape, and the curved walls of the floor pressing bars are pressed on a lateral wallboard. Compared with the prior art, the passenger room underframe internal installation structure easy to dismount for the urban rail vehicle has the beneficial effects that the installation ways of the lateral wallboard, the end electrical cabinet and the aluminum honeycomb floors in a door area are changed through the structure, the problem that dismounting and mounting of the vehicle body underframe are troublesome is solved, and using is extremely convenient and fast.

Description

technical field [0001] The invention is applicable to the interior installation of the passenger compartment chassis of urban rail vehicles, and relates to an easily disassembled passenger compartment chassis interior structure of urban rail vehicles. Background technique [0002] The internal structure of the passenger compartment chassis of urban rail vehicles mainly includes floor mounts, cold-proof materials, aluminum honeycomb floor, floor cloth, and floor beading. [0003] Such as figure 1 As shown, in the interior structure of the underframe of the passenger compartment of the urban rail vehicle in the prior art, the floor mounting seat is installed on the underframe of the car body or in the profile slot of the underframe of the car body by bonding or clamping. The aluminum honeycomb floor is paved on the floor mounting base, and the two sides are fixed on the floor mounting base by rivets or bolts. The aluminum honeycomb floors are connected by screws. The floor ...

Problems solved by technology

[0004] like figure 2 As shown, another function of the floor bead is to install the side wall panel. The lower part of the side wall panel is inserted into the slot of the floor bead. The disadvantage of this structure is that once the floor bead needs to be removed, the side wall panel must be removed first.

[0005] like image 3 As shown, when installing the aluminum honeycomb floor in the door area and the aluminum honeycomb floor in the window area, install the aluminum honeycomb floor in the door area first, and then install the aluminum honeycomb floor in the window area. Removal of adjacent window area aluminum honeycomb floor

[0006] like Figure 4 As shown, the end electrical cabinet is directly fixed on the profile of the aluminum honeycomb floor. The disadvantage of this connection method is that once the end aluminum honeycomb floor needs to be removed, the end electrical cabinet needs to be removed first.

[0007] In order to solve the problem of troublesome installation and disassembly of the underframe, it is not necessary to remove the side wall panels and end electrical cabinets when replacing the interior parts of the underframe in the passenger room, and it is not necessary to remove the aluminum honeycomb floor in the adjacent window area when removing the aluminum honeycomb floor in the door area.
