Description
Technical Field
The invention relates to the technical field of railway vehicles, in particular to a fireproof partition door structure.
Background
At present, the partition wall structure of the existing domestic locomotive only has the functions of communicating a cab with equipment rooms/passengers and observing. However, with the improvement of the safety performance requirement of the industry, the corresponding standards clearly suggest that the railway vehicle needs to be provided with a fireproof partition structure. The fireproof partition door is arranged between the cab and the equipment room/passenger room, and is particularly arranged at the joint of the cab area and the equipment room/passenger room, so that drivers and passengers can conveniently pass through the cab area and the equipment room/passenger room under normal conditions; however, in case of fire emergency, the fireproof partition is used for blocking the spread of flame within a certain time, giving the passengers the opportunity to escape, and meanwhile, the fireproof partition also needs to have the function of observing and watching.
Two important fire performance indexes of the fire partition are integrity and heat insulation respectively. Integrity refers to the ability of a fire partition structure to not burn through when the fire is set up on one side of the fire partition structure, resulting in the spread of the fire to the other side. Thermal insulation refers to the ability of a flame to rise on one side of a fire-resistant partition structure without the temperature on the other side of the partition structure rising above a value specified by a standard.
According to the classification of electric locomotives, the fire-proof partition of the locomotive body generally meets the requirements of fire-proof heat insulation and integrity for 15 minutes, and the theoretical temperature of the fire-exposed surface of the fire-proof partition is 738 ℃.
Failure of the refractory integrity is considered if:
a) flame appears on the back fire surface of the sample and continuously burns for more than 10 s; or
b) In the case where a probe is suitable for use,
c) a probe with the diameter of 6mm can enter the furnace through the sample and can move for a distance of at least 150mm along the direction of the crack; or
d) A probe having a diameter of 25mm can be passed through the sample into the furnace.
Failure of the fire-resistant insulation is considered if:
a) the average temperature rise of the back fire surface of the sample exceeds 140 ℃; or
b) Any thermocouple on the back fire surface of the sample, including a movable thermocouple, has the highest temperature rise of over 180 ℃; or
c) The integrity is lost.
At present, the fire-proof performance of the existing partition wall structure cannot meet the requirements.
Disclosure of Invention

In order to solve the technical problems, the invention adopts the following technical scheme:
a fireproof partition door structure comprises a door frame with a door opening and a door leaf hinged with the door frame, wherein the door leaf is used for opening or closing the door opening; the door leaf comprises a first door plate, a second door plate and a door framework, wherein the first door plate and the second door plate are arranged in parallel at intervals, the door framework is connected between the first door plate and the second door plate, the outer wall surface of the first door plate forms a fire receiving surface, sealing strips are arranged on the door edges of the first door plate and the second door plate, and the sealing strips extend to the door edges wrapping the corresponding door plates along the peripheries of the corresponding door plates; the sealing strip comprises a clamping part with a U-shaped cross section and a hollow sealing part connected with the clamping part, the door edge of the door plate is clamped in the U-shaped groove of the clamping part, and the hollow sealing part is used for being abutted against the door frame, so that sealing is established between the door edge and the door frame.

In order to facilitate the installation of the fire-resistant glass and the attractive appearance of glue, the back fire surface can adopt common toughened glass and is installed by using a flame-retardant sealing strip.
A baffle is riveted on the outer side of the refractory glass; the inner side is welded or riveted with the proportional mounting frame to form a closed box-shaped structure, so that the glass is prevented from falling off after the bonding glue is heated and loses efficacy.
The fireproof partition door has the advantages that the fireproof performance can meet the requirements of fireproof heat insulation and integrity specified in EN 45545-3, the passing and lookout functions are achieved, and the fireproof partition door has the advantages of being easy to achieve, simple to maintain, high in safety and the like.
