Abstract

The utility model provides a fire-proof vehicle body belonging to the technical field of vehicles, which aims to solve the problem of fire protection on vehicles. The utility model adopts the technical scheme that the vehicle body is made up of a vehicle housing and an interior trim, wherein, a fire-proof door is arranged on the end walls at the two ends of the vehicle housing, flame-retardant fibers are arranged on the inner walls of the end walls, a fire-proof coating is arranged on the inner wall of the side wall of the vehicle housing, and a fire-proof partition screen is arranged in the interlayer between the top plate of the passenger compartment and the top plate of the vehicle housing. The utility model takes various fire-resisting measures to control the spreading of fires in a maximal manner, thereby saving time for passengers to escape for life and for fire fighters to extinguish the fires, which in turn can effectively reduce losses caused by fires.

Description

A kind of fire prevention vehicle body

Technical field

The utility model relates to a kind of vehicle body that can effectively slow down the railway vehicle of fire spread, belongs to the vehicle technology field.

Background technology

Railway vehicle is notable features such as freight volume is big, conveying efficiency height because of having, and are the topmost vehicle always.Because the passenger train running velocity is fast, seat, ceiling and other ornament materials of train are combustible material mostly, in case catch fire, fire meeting rapid spread, be difficult to control, occupant's density is big in addition, fire attack difficulty height in the operational process, and consequence is often very serious, therefore, the fire retardancy to railway vehicle has proposed higher requirement.

Although passenger train vehicle body interior material and each subsystem have all been taked necessary fire precaution, but, existing passenger train vehicle body takes all factors into consideration because lacking in the design production process, local fire is easy to spread to other position, causes the whole fire resistance of passenger vehicle unsatisfactory.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of whole fire resistance good fire prevention vehicle body.

Problem described in the utility model realizes with following technical proposals:

A kind of fire prevention vehicle body, be made of car body shell and interior trim, the headwall at described car body shell two ends is provided with fire protection gate, and the headwall inwall is provided with fire resistance fibre, car body shell side inner wall has fire protection coating, is provided with fire prevention in the interlayer between guest room top board and car body sheath top plate and cuts off.

Above-mentioned fire prevention vehicle body, described fire protection gate are to open pull door, are made up of doorframe and fireproof glass, and a described side to open pull door is an automatically-controlled door, and opposite side is a manually operated door.

Above-mentioned fire prevention vehicle body, described fire protection coating are positioned at the side window below.

The utility model is being taked multiple fire precaution simultaneously on the body structure: fire protection gate on the headwall inwall and fire resistance fibre are used to stop fire to spread to adjacent car; Fire prevention between guest room top board and the car body sheath top plate in the interlayer cuts off can prevent that pyrotechnics from spreading along interlayer; The side wall of side window bottom, the zone of car body moment of flexure maximum is coated with fire protection coating in these zones when being presence of fire, and the fire protection coating heat absorption is expanded during presence of fire, thereby delays the time that the car body weak part loses rigidity.The utility model stops fire spread to greatest extent by taking multiple fire precaution, races against time for passenger escape and putting out a fire to save life and property of fire, the loss that can effectively reduce fire and caused.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Each label is among the figure: 1, headwall, 2, fire protection gate, 3, fire protection coating, 4, fire prevention cuts off, 5, fire resistance fibre, 6, fastening nail, 7, side wall, 8, fireproof glass, 9, doorframe, 10, the car body shell, 11, side window, 12, seat.

The specific embodiment

The utility model is from the fire protection requirement of EMU level, start with from the automobile interior position, a whole set of practicable interior fire proof construction is provided, solve the fire safety problem of vehicle, slow down spreading of fire, guarantee train after fire takes place, can move 15 minutes, improve passenger and crew member's safety factor with the speed of 80KM/h.

Referring to Fig. 1, Fig. 2, the utility model comprises in the fire precaution of taking on the body structure: fire protection gate 2 and fire resistance fibre 5 are set on headwall 1 inwall; Fire protection gate 2 is to open pull door, is made up of doorframe and fireproof glass, and a described side to open pull door is an automatically-controlled door, and opposite side is a manually operated door.When car operation, automatically-controlled door is a normally off, the state of manually operated door for often opening.Normally closed automatically-controlled door not only effectively reduces the noise in the car, in the time of also can catching fire in the compartment of unmanned nurse, effectively stops fire spreading to other compartments.And the manually operated door of often opening can improve passenger's evacuation speed when fire takes place.Two adjacent gangway doors are made as manual form and automatic form, can effectively prevent spreading of fire, have considered passenger's evacuation speed again.Fire prevention is set in the interlayer between the top board of guest room top board and car body shell 10 cuts off 4; Side wall 7 inwalls in side window 11 bottoms are coated with fire protection coating 3.

Referring to Fig. 3, Fig. 4, in side wall 7 bottoms of window area and the side door zone of a car, the maximal bending moment zone of car body when being presence of fire.Be coated with fire protection coating 3 in these zones, during presence of fire, fire protection coating 3 heat absorptions are expanded, thereby delay the time that loses rigidity of car body weak part.

Referring to Fig. 5, Fig. 6, at headwall 1 inwall of vehicle fire resistance fibre 5 is installed, fire resistance fibre 5 is fixed by fastening nail 6, matches with fire protection gate 2, can effectively delay fire spreading to adjacent car.

Still, the fire prevention partition 4 that a fire proofing is made is housed in the interlayer between guest room top board and car body shell 10 top boards, can prevents that pyrotechnics from spreading along interlayer referring to Fig. 1.

Referring to Fig. 7, open pull door is made up of doorframe 9 and fireproof glass 8.Wherein a side is an automatically-controlled door, and opposite side is a manually operated door.Two kinds of doors are fire protection gate, and they have approximate framework, flame resistant glass and hermetically-sealed construction.Every kind of Men Jun is designed to have 15 minutes fire resistance property, when closing for two, can improve the vehicle body fire savety greatly.

Interior trim fire proof construction of the present utility model is installed on the end top and the sidepiece of vehicle, in the anti-fire action of performance separately, complements each other again, has carried out the protection of integrated form from stoping fire spread, protection car body fermentation such as rigidity when the fire.
