Light and fire-resistant partition door of metro driver cab

Abstract

The invention discloses a light and fire-resistant partition door of a metro driver cab. The light and fire-resistant partition door of the metro driver cab comprises a door frame and a door leaf. The door leaf is movably connected with the door frame through hinges and fasteners. The door leaf comprises a framework and core materials. The light and fire-resistant partition door of the metro driver cab is characterized in that the framework is made from aluminum alloy sections; the core materials are aluminum cellular boards; aluminum skins are bonded to the surfaces of the two sides of the core materials correspondingly; a groove is formed in the end face, facing the door frame, of the framework; an expandable graphite rubber strip I is arranged in the groove; an expandable graphite rubber strip II is arranged on a boss at the pressing junction of the door frame and the door leaf; and two layers of ultrathin steel structure fireproof coatings are sprayed on the passenger room side of the door frame and the passenger room side of the door leaf correspondingly. Compared with the prior art, the light and fire-resistant partition door of the metro driver cab has the beneficial effects that the lightweight characteristic is achieved, the weight can be reduced by 80 kg, an excellent structural fire-resistant function is achieved, and the fire-resistant capability can reach 30 min which is far longer than that of a standard requirement.

Description

technical field [0001] The invention belongs to the field of rail transit vehicle driver's cab partition doors, relates to a passage door between a driver's cab and a passenger compartment in a railway vehicle, and relates to a light-weight subway driver's cab fire-resistant partition door. Background technique [0002] At present, there are mainly two types of partition doors for rail vehicle cabs, one is an ordinary aluminum honeycomb structure partition door with poor fire resistance, and the other is a stainless steel structure partition door with relatively good fire resistance. The aluminum honeycomb structure door is light in weight and easy to install, but it cannot provide relatively safe driving conditions for drivers in case of fire, is not conducive to evacuation and escape of people under fire conditions, and does not meet the requirements of relevant fire protection standards for rail vehicles; and The partition door of stainless steel structure has a certain s...
