Abstract

A kind of tip-up set structure, it is characterized in that: seat lower box adopts sectional materials cage and aluminium sheet structure, seat lower box and floor gap place establish one deck to prevent fires expandable sealant, one deck fire-retarding paint is sprayed at whole seat lower box sectional materials cage and aluminium sheet inner surface, in the bonding fire prevention expansion in inspection door doorframe place adhesive tape, between chair framework and side wall steel construction, arrange rubber slab and T-shaped bolt blend rubber overlap and wrap up, connected by double leval jib and air spring between seat panel calcaneum frame.The utility model to be prevented fires expandable sealant by establishing one deck at seat lower box and floor gap place, add on cover plate in whole seat lower box inner skeleton and spray one deck fire-retarding paint, in the bonding fire prevention expansion in inspection door doorframe place adhesive tape, achieve structure fire requirement in 20 minutes; By adding rubber slab and T-shaped practicable use rubber sleeve wraps up between chair framework and side wall steel construction, car external noise is avoided to pass to interior by car body and chair framework; Very little power is used just can seat panel to be dug fast by double leval jib air spring structure.

Description

A kind of tip-up set structure

Technical field

The utility model relates to a kind of tip-up set structural design of railcar.

Background technology

Guest room seat takes capital equipment as railcar passenger, at present, domestic existing seat is cantilever seat stationary structure, electrical equipment is arranged in seat lower box, seat casing is just equivalent to guest room partition, and the existing fire proof construction of partition is that phenolic resins pastes section material framework, and one deck ceramic fibre is installed at the phenolic resins back side, this structure occupies very large seat housing interior volume, can not meet the installing space of electrical equipment; Meanwhile, subway chair framework and side wall Steel Structure Installation mode are and are rigidly connected, and car external noise passes in car by steel structure of car body and chair framework, increase noise in car, and then affect the comfortableness taken; Current railcar tip-up set structure is also had to be the single shaft upset of backrest top, on the south Hong Kong six people seat be example, length is 2600mm, single shaft upset axiality is poor, clamping stagnation situation is often there is again in switching process, the weight of six people's stainless steel seats is probably 50kg simultaneously, needs two people seat can be dug, wastes time and energy.

South, Hong Kong Hong Kong subway is automatic driving vehicle, head car front position is without drivers' cab partition, originally the electrical equipment of guest room in drivers' cab partition and drivers' cab is arranged in without installation site, certainly will to develop a kind of Novel chair structure and place electrical equipment, electrical equipment in drivers' cab electricity partition is all placed in guest room under-seat casing, and demand fulfillment has the performance of 20 minutes structure fires and noise reduction sound insulation, but also maintenance of electrical equipment under wanting Convenient chair, therefore a kind of tip-up set structure of research and design meets structure fire, noise and to be convenient to the requirement of electric equipment maintenance imperative.

Utility model content

The purpose of this utility model is to provide a kind of tip-up set structure, can meet structure fire, noise and be convenient to the requirement of electric equipment maintenance.

For achieving the above object, the utility model provides a kind of tip-up set structure, it is characterized in that: seat lower box adopts sectional materials cage and aluminium sheet structure, seat lower box and floor gap place establish one deck to prevent fires expandable sealant, one deck fire-retarding paint is sprayed at whole seat lower box sectional materials cage and aluminium sheet inner surface, in the bonding fire prevention expansion in inspection door doorframe place adhesive tape, between chair framework and side wall steel construction, arrange rubber slab and T-shaped bolt blend rubber overlap and wrap up, connected by double leval jib and air spring between seat panel calcaneum frame.

The utility model to be prevented fires expandable sealant by establishing one deck at seat lower box and floor gap place, add on cover plate in whole seat lower box inner skeleton and spray one deck fire-retarding paint, in the bonding fire prevention expansion in inspection door doorframe place adhesive tape, achieve structure fire requirement in 20 minutes; By adding rubber slab and T-shaped practicable use rubber sleeve wraps up between chair framework and side wall steel construction, car external noise is avoided to pass to interior by car body and chair framework; For convenience to the electrical design repair and maintenance in seat lower box, seat panel can upwards be dug, and is realized, use very little power just can seat panel be dug fast by double leval jib air spring structure.

Detailed description of the invention

With reference to Fig. 1, seat lower box 1 be aluminium sheet structure, and seat lower box 1 and floor 2 seam crossing establish one deck to prevent fires expandable sealant 3,

With reference to Fig. 2, spray one deck fire-retarding paint at the inner right baffle-plate 4 of whole seat lower box, right baffle plate 5, inspection door 6, inspection door 7 inspection door 8 inner surface.

With reference to Fig. 3, the bonding 3mm fire prevention in mount pad 10 place expansion adhesive tape 11 in the middle of doorframe, partition door 6 and inspection door 7 are pressed in fire prevention expansion adhesive tape 11.

With reference to Fig. 4, the bonding 3mm fire prevention expansion adhesive tape 12 at mount pad 9 place, doorframe both sides, partition door 6 is pressed in fire prevention expansion adhesive tape 12.

With reference to Fig. 5, Fig. 6, between chair framework 17 and side wall steel construction 21, rubber slab is set, rubber slab comprises different-thickness rubber slab 16 and 15mm rubber slab 18, T-shaped bolt 13 uses rubber sleeve 20 to wrap up, cut off the noise transmitted outside car, its light plate 15 and steel plate 19 play the effect of support rubber plate, install seat sliding block 14 and T-shaped bolt 13 with the use of.

With reference to Fig. 7, for convenience to the electrical design repair and maintenance in seat lower box, seat panel 24 can upwards be dug, and realized by double leval jib 22 air spring 23 structure, use very little power just can seat panel be dug fast, 25 is chair frameworks.

Claims

1. a tip-up set structure, it is characterized in that: seat lower box adopts sectional materials cage and aluminium sheet structure, seat lower box and floor gap place establish one deck to prevent fires expandable sealant, one deck fire-retarding paint is sprayed at whole seat lower box sectional materials cage and aluminium sheet inner surface, in the bonding fire prevention expansion in inspection door doorframe place adhesive tape, between chair framework and side wall steel construction, arrange rubber slab and T-shaped bolt blend rubber overlap and wrap up, connected by double leval jib and air spring between seat panel calcaneum frame.
