Embodiment Construction

[0106] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0107] see Figure 1-5 shown;

[0108] Invented double-deck EMU chassis, including:

[0109] Two end chassis 1;

[0110] Two partition walls 2;

[0111] a floor 3 for connecting the two partition walls 2; and

[0112] Two side beams 4, which are used to connect the two end chassis 1; also include

[0113] a transition connection structure, which is used to connect the partition wall 2 and the end chassis 1;

[0114] One side of the transition connection structure is fixedly connected to the end chassis 1 in a plug-in manner, and the other side is fixedly connected to the partition wall 2 in an overlapping manner, so that the end chassis 1 and the partition wall 2 can be divided into blocks.

[0115] Specifically, see figure 1 As shown, in ...

Abstract

The invention discloses a double-decker multiple unit base frame, a base frame assembly position-fixing device and a base frame assembly position-fixing method, and belongs to the technical field of high-speed railway vehicle manufacturing. The double-decker multiple unit base frame comprises two end base frames, two partition walls, a floor for connecting the two partition walls, two edge beams for connecting the two end base frames, and transition connecting structures for connecting the partition walls and the end base frames, wherein one side of each of the transition connecting structuresis fixedly connected to the corresponding end base frame in an inserted manner, and the other side thereof is fixedly connected to the corresponding partition wall in a lap joint manner, so that themodularization of the end base frames and the partition walls is achieved. The base frame assembly position-fixing device comprises a platform, wherein the platform is provided with two supporting mechanisms, two assembling mechanisms, a plurality of supporting and clamping mechanisms, four position-fixing devices capable of forming a rectangle, and supporting and pressing mechanisms for connecting the partition walls and the transition connecting structures. The double-decker multiple unit base frame, the base frame assembly position-fixing device and the base frame assembly position-fixing method have the beneficial effects of reducing the assembling difficulty of the base frame, shortening the manufacturing period of base frame assembly, and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of manufacturing high-speed rail vehicles, in particular to a double-layer EMU underframe, an underframe composite positioning device and a positioning method thereof. Background technique [0002] At present, the double-deck EMU is a new type of EMU developed to meet the needs of large passenger flow in urban rail transit and trunk railways. It has the characteristics of large transportation volume, fast speed, safety and reliability; [0003] In the prior art, in order to ensure the space requirements of double-deck EMUs, the underframe of double-deck EMUs adopts a horizontal design structure, and the end underframes, partition walls, and horizontal floors are plug-in structures. figure 1 As shown, one end of the partition wall is inserted into the end chassis, and the other end is inserted into the floor. Due to the wide width of the vehicle body, it is difficult to assemble the partition wall, the end ch...
