The invention discloses a rail transit platform door structure with a secondary insulating function, which comprises a left sliding door, a right sliding door, a left column, a right column, a threshold, and a lintel, wherein both the left column and the right column comprise a column square tube and a column wrapping plate, and the column wrapping plate is wrapped on the outer surface of the column square tube; the threshold comprises a threshold liner plate and a threshold panel, and the threshold panel is wrapped on the outer surface of the threshold liner plate; the lintel is arranged on amain body structure above a platform door through a lintel mounting plate in a connecting way, and a top box front cover plate is arranged above the lintel; the lintel, the column wrapping plate andthe threshold panel are made of sheet metal to form a metal outer surface capable of being contacted by passengers in a platform door passage area, and the lintel, the column wrapping plate and the outer surface of the threshold panel are coated with a first insulating layer. According to the rail transit platform door structure with the secondary insulating function provided by the invention, the dangers such as electric shocks and accidents of discomfort caused by the potential difference between the metal outer surface capable of being contacted by passengers and the body when the passengers pass by vehicles going in or out of the platform door passage area can be avoided.
Description
technical field [0001] The invention relates to the technical field of rail vehicle components, in particular to a rail transit platform door structure with a secondary insulation function. Background technique [0002] In the platform door system of rail transit, it is usually required that the platform door is insulated from the civil structure (that is, primary insulation) so that an equipotential is formed between the platform door, the track, and the carriage, so as to avoid accidents when passengers enter and exit the vehicle through the platform door passage area. The potential difference between the metal outer surface of the passenger's accessible part and the human body will cause dangerous or uncomfortable accidents such as electric shock. [0003] However, in the actual operation of rail transit, sometimes seepage and water leakage occur due to accidents in the civil structure of the platform, etc., causing the primary insulation between the platform door and the...
