Insulating member of station door assembly

Abstract

The invention provides an insulating member of a station door assembly. The insulating member of the station door assembly comprises an insulating layer and a sectional bar for constructing the station door assembly, wherein the sectional bar is coated with an insulating layer. Door frame sectional bars of door frames are coated with insulating layers, and the door frames are interconnected through detachable fasteners, so that the replacement is easy; upright columns and composite insulating materials are subjected to global extrusion forming through steelwork, and weld segments are reserved,so that the problem that composite materials cannot meet the requirements on high temperature during the welding of upright column sectional bars and bottom plates is solved; the stress requirementsand reliability of the upright columns are met, and the insulating property of the upright columns cannot be affected. The condition that passengers get an electric shock due to touch with station doors can be avoided, and the performance is stable and reliable.

Description

technical field [0001] The invention relates to the design field of platform doors of subway stations, in particular to an insulating platform door assembly component. Background technique [0002] Since most of the current subway lines use steel rails as return rails, the train and the rails form an equipotential through the steel wheels, so that there is a potential difference between the platform door and the train. In order to ensure the safety of passengers and staff, the current method is The platform doors are connected to the rails with copper core cables to achieve the same potential between the doors and the platform doors. However, the platform doors need to prevent stray currents from flowing into the platform doors through the tracks and then into the structural steel bars. Therefore, the door body of the platform door should be installed insulated on the platform. [0003] In the past, the platform door insulation installation scheme of domestic and foreign su...

AI Technical Summary

Problems solved by technology

Insulation failure will cause stray current to flow through the door into the reinforcement and corrode the reinforcement

At the same time, the electrification of the door body will easily lead to sparks with the surrounding metals, posing hidden dangers to operational safety.

According to the above-mentioned schematic diagram of platform door insulation installation and door body structure, if the platform door insulation installation fails, passengers will directly touch the door frame and uprights when getting on and off the train, and the current door frames and uprights are made of metal, which will cause electric shock to passengers Danger
