Description

Technical Field

[0001] The utility model belongs to the field of rail transit platform doors, and in particular relates to a sealing and insulating installation structure of platform doors. Background Art

[0002] With the rapid development of rail transit, full-height platform doors are used more and more widely. Usually, there is a gap between the columns of full-height platform doors and the top beam of the platform, which will transmit the noise, cold and hot air currents in the track into the platform. Rear sealing plates are required for sealing and isolation. However, the position of the rear sealing plate is a semi-concealed equipment, and it is particularly difficult to achieve its insulation and sealing.

[0003] At present, the sealing of the rear cover plate of the full-height platform door mostly adopts the method of connecting the upper cover plate to the platform top beam by bolts, and connecting the lower cover plate to the door machine beam by bolts. The upper and lower cover plates are fixedly connected by a sealing strip. This structure may cause the connection between the upper and lower cover plates to fail due to vibration caused by multiple trains passing by, and assembly errors are easily generated in the process of connecting the platform top beam with multiple bolts, resulting in low installation efficiency. Summary of the invention

[0007] The inclined support plate is an integrally formed structure, and is provided with an upper transverse connecting portion and a lower transverse connecting portion which are parallel to the platform top beam.

[0008] The rear sealing plate is provided with a first mounting hole, which is a strip-shaped hole.

[0009] The sealing strip is an airbag structure, which is composed of a plurality of airbags that penetrate axially and are closed at both ends. The upper part of the sealing strip is provided with two raised sealing lips, the middle part is provided with a cavity, and the lower part is provided with a locking part.
