Abstract

The invention discloses an insulation threshold device of an urban rail transit platform door system. The insulation threshold device comprises a platform side step plate (1), a platform side insulation isolation plate (3), a platform side threshold base plate (5), a rail side step plate (2), a rail side insulation isolation plate (4) and a rail side threshold base plate (6), wherein the platformside step plate (1), the platform side insulation isolation plate (3), and the platform side threshold base plate (5) are connected together through first screws and nuts and the rail side step plate(2), the rail side insulation isolation plate (4) and the rail side threshold base plate (6)are connected together through second screws and nuts. The platform side threshold base plate (5) is insulated and isolated from the platform side step plate (1) through the platform side insulation isolation plate (3), and an insulation sleeve (7) is arranged at the joint of the platform side threshold base plate (5), the platform side insulation isolation plate (3) and the platform side step plate (1) to completely insulate the outer surface of a platform threshold; the rail side threshold base plate(6) is insulated and isolated from the rail side step plate (2) through the rail side insulation isolation plate (4), and the insulation sleeve (7) is also arranged at the joint of the rail side threshold base plate (6), the rail side step plate (2) and the rail side insulation isolation plate (4), so that the outer surface of the rail threshold is completely insulated and the insulation thresholddevice has a self-insulation function.

Description

technical field

[0001] The invention relates to a building component of an urban rail transit platform door system, in particular to a threshold device with self-insulating function installed at the urban rail transit platform door. Background technique

[0002] The insulation of the door body of the urban rail transit platform door to the ground is a difficult point in the platform door industry, and it is quite difficult to achieve complete insulation to the ground. The threshold of the platform door is used as a stepping support structure for passengers to get on and off the train. It is in direct contact with the passengers and is close to the train body. Although the entire platform door system has been insulated from the ground and connected to the rail at an equipotential connection, the effect cannot be fully guaranteed. Sometimes , There is a potential difference between the train body and the platform door body. At this time, if there are metal parts at the bottom ...

Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention. .

[0022] Such as figure 1 and figure 2 As shown, the insulation threshold device of the urban rail transit platform door system of the present invention includes a platform threshold insulation system and a track threshold insulation system platform door respectively located on both sides of the platform door 15 and spaced at a certain distance. The platform threshold insulation system includes a platform side step board 1 , a platform side insulation isolation plate 3 and a platform side threshold base plate 5 connected together by first screws and nuts. The track-side sill insulation system includes a...
