Abstract

The invention belongs to the technical field of rail transit equipment, and particularly relates to a through passage floor device mainly structurally comprising a floor support assembly, a corridor floor assembly and a gangway foot plate assembly and is designed into an ultrathin structure so as to fully utilize the limited space at the bottom of a low-floor vehicle, and a floor surface stretches across a through passage and a vehicle body corridor. three rotation points are formed in the center position of a floor and the floor support assembly; the corridor floor support is made of nylon and has mute and wear-resisting effects; the floor support assembly is provided with an angular contact spherical sliding bearing and a spherical bearing; displacement actions such as rotation, side rolling and jolting required by vehicle movement are met; sealing rubber strips are mounted on all separation faces of a spherical bearing installation cavity in the floor supporting assembly, two sealing rubber strips are mounted below a corridor floor cover plate, waterproof sealing can be achieved, and no noise exists. The through passage floor device is simple in structure, the overall height of the floor system is reduced on the premise that the line requirement is met, and the use requirement of a low-floor vehicle model is met.

Description

Technical field: [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a through-passage floor device, which is relatively low in height and is suitable for low-floor through-passage vehicles. Background technique: [0002] The through passage is an internal passage for passengers to walk freely from one compartment of rail transit vehicles to another and make passengers feel safe and comfortable. The floor system is one of the important components of the through passage. Passengers rely on the floor when passing through two carriages. The carrying capacity of the system is realized. [0003] The floor system in the prior art, Chinese patent 201910610547.6 discloses a through-passage floor of a tram, comprising: a first fixing plate installed at the end of the first compartment; a semicircular structure, the The linear end of the semicircle structure is connected with the first fixed plate; the second fixed plate is inst...
