Problems solved by technology

[0004] However, the current stair structure takes up a large space, and the multiple first pillars 1 arranged at intervals at the bottom of the step assembly 3 make it impossible to place parts of double-deck rail cars in this space, and there are 6 inverters and vertical air ducts for double-deck rail cars. It can be installed on the side of the stairs, and multiple first pillars 1, second pillars 2 and step components 3 require relatively complicated operation procedures during the installation process, and the complicated installation procedures brought about by the complex structure and inevitable It is believed that the installation error makes the final installation effect and user experience of the staircase unsatisfactory

Embodiment 1

[0054] Figure 4 It is a structural schematic diagram of the staircase provided by Embodiment 1 of the present invention. Figure 5 It is a side view of the staircase provided by Embodiment 1 of the present invention. Image 6 It is provided by Embodiment 1 of the present invention Figure 4 Partial schematic diagram of part B in . Figure 7 It is provided by Embodiment 1 of the present invention Figure 4 Partial schematic of part C in . Figure 8 It is a structural schematic diagram of a staircase provided with handrails provided in Embodiment 1 of the present invention.

[0055] like Figure 4 to Figure 8 As shown, Embodiment 1 of the present invention provides a kind of staircase, and this staircase is used for the connection of the upper carriage and the lower carriage of double-deck rail passenger car. Most of the stairs currently used for double-deck rail cars include a vertically arranged first pillar and an obliquely arranged second pillar, the first pillar is s...

Embodiment 2

[0071] Figure 9 It is a structural schematic diagram of the staircase provided by Embodiment 2 of the present invention. like Figure 9 As shown, the second embodiment of the present invention also provides a staircase.

[0072]On the basis of the first embodiment above, in the staircase provided by this embodiment, the first fixed plate 10 and the second fixed plate 20 are arc panels, and the bending radii of the first fixed plate 10 and the second fixed plate 20 are the same and The bends are facing the same direction. It should be noted that in some double-deck rail passenger cars, the installation space at the ends of the upper and lower compartments is relatively narrow, and in order to adapt to the installation of the brake pipeline system, electrical equipment or fire-fighting facilities inside the compartment, the first When the fixed plate 10 and the second fixed plate 20 cannot be set to a linear plane plate, both can be set as an arc plate, Figure 9 A possible...

Embodiment 3

[0077] Figure 10 It is a schematic structural diagram of the interior of the compartment of the double-deck rail passenger car provided by Embodiment 3 of the present invention. Figure 11 It is provided by Embodiment 3 of the present invention Figure 9 Partial schematic diagram of part D in .

[0078] On the basis of above-mentioned embodiment one and embodiment two, as Figure 10 and Figure 11 As shown, the third embodiment of the present invention also provides a double-deck rail passenger car, including an upper compartment and a lower compartment vertically stacked up and down, and the same end of the upper compartment and the lower compartment are connected by at least one section of the above-mentioned stairs .

[0079] In the above-mentioned double-deck rail passenger car, it is optional that the ends of the same end of the upper compartment and the lower compartment are connected by multiple staircases, the multiple staircases are connected end to end, and the ...

Abstract

The invention provides a stair and a dual-layer railway vehicle. The stair is used for connecting an upper layer compartment and a lower layer compartment of the dual-layer railway vehicle. The staircomprises a first fixing plate, a second fixing plate and a step piece located between the first fixing plate and the second fixing plate. One ends, in the length direction, of the first fixing plateand the second fixing plate are in overlapped connection with a floor of the upper layer compartment, the other ends of the first fixing plate and the second fixing plate are in overlapped connectionwith a floor of the lower layer compartment, and an included angle is formed between the horizontal direction and the extending direction of the two fixing plates; the stair piece comprises a plurality of stair units, each stair unit comprises a treading face which is used for allowing a passenger to tread on and arranged in the horizontal direction and a supporting face for supporting the treading face, and the included angle between the treading face and the supporting face is larger than 0 degree and smaller than 90 degrees. The dual-layer railway vehicle comprises the stair. According to the stair and the dual-layer railway vehicle, the installation occupied space can be greatly reduced, the installation procedures are simplified, the installation precision is improved, and therefore the using comfort of a user is improved.

Description

technical field [0001] The invention relates to the technical field of rail passenger car design and manufacture, in particular to a staircase and a double-deck rail passenger car. Background technique [0002] Stairs are used as traffic links between floors in buildings and when the height difference is large. Although elevators and escalators are relatively common at present, in order to ensure the safety of personnel when escaping from a fire, stairs are still selected as the main transportation work. As one of the main means of transportation for short-distance or long-distance travel, increasing the capacity, improving space utilization, improving comfort, and reducing costs have always been the unremitting goals of railway passenger vehicles in the development process. Therefore, in order to meet The above requirements arise at the historic moment for double-deck high-speed EMUs. Stairs are the passages connecting the upper and lower floors inside double-deck rail car...
