Description

Technical Field

[0001] The present invention relates to the field of rail transit platform door systems, and in particular to a novel insulating threshold of a platform door. Background Art

[0002] With the growing development of the urban rail transit industry, the insulation safety issues of platform door systems have become increasingly prominent. The insulation problem of platform door thresholds has always been a difficult issue in the industry. Due to the potential difference caused by stray current and static electricity between the train, platform, and platform door, when passengers enter the train through the platform door threshold, the step voltage generates current, which can cause discomfort or injury to the passengers.

[0003] Current technologies often insulate the platform door at the junction with the building, or insulate the lining, but this makes it difficult to achieve complete insulation from the ground. Because existing thresholds are mostly metal and non-insulated, dusty or humid environments can easily lead to electrical contact between the threshold surface, the pillars, and the ground, causing insulation failure. Therefore, it is necessary to develop a new type of insulated platform door threshold to improve insulation effectiveness. Summary of the Invention

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The novel platform door insulating threshold of the present invention includes a surface-insulated threshold comprising a platform-side threshold 11 and a track-side threshold 12. The gap between the platform-side threshold 11 and the track-side threshold 12 serves as a guide groove for the sliding door guide shoe. The sliding door guide shoe includes a guide shoe mounting frame 27 and sliding strips 210 on both sides. A gap compensation device 28 is provided on the rear surface of the track-side threshold 12. The gap compensation device 28 is formed by vulcanizing rubber and an inner lining steel plate. Column insulation blocks are provided at the locations where the threshold meets the columns 212 on both sides. The column insulation blocks are made of an insulating material such as FRP and insulate the threshold from the columns 212. A surface-insulated door body and column edging are installed on the upper portion of the threshold. The above structures together constitute the overall platform door insulation solution for areas accessible to the public.

[0024] The pillars 212 of the present invention include a left pillar 15 and a right pillar 16. The platform-side threshold 11 and the track-side threshold 12 are installed between the left and right pillars 15 and 16. The pillar insulation blocks include a left insulation block 13 and a right insulation block 14. The left insulation block 13 is installed between the platform-side threshold 11 and the left pillar 15, and the right insulation block 14 is installed between the platform-side threshold 11 and the right pillar 16. A gap-filling device 17 made of vulcanized rubber is installed on the side of the track-side threshold 12. The platform-side threshold 11 and the track-side threshold 12 include surface-insulated threshold panels, threshold liners, and removable threshold liners. The platform-side threshold 11 includes a platform-side threshold panel 21, a platform-side threshold liner 23, and a platform-side spliced ​​threshold liner 24. The track-side threshold 12 includes a track-side threshold panel 22, a track-side spliced ​​threshold liner 25, and a track-side threshold liner 26. The platform-side door sill 11 and the track-side door sill 12 are mounted to the column base plate 211 of the column 212 with fastening screws. The column base plate 211 is attached to the bottom support 29 with fasteners. The gap between the two door sills serves as a guide groove for the sliding door. The guide shoe, consisting of the guide shoe mounting bracket 27 and the slide bar 210, moves within this guide groove. Equipotential screws 24 are installed on the platform-side door sill 11 and the track-side door sill 12, while equipotential screws 13 are installed on the column base plate 211. The surfaces of the platform-side door sill panel 21 and the track-side door sill panel 22 are coated with a carborundum coating 6, which effectively increases the wear resistance and anti-slip properties of the contact surface. The platform side threshold panel 21 and the track side threshold panel 22 are connected to the platform side threshold lining 23 and the track side threshold lining 26, the platform side spliced ​​threshold lining 24 and the track side threshold spliced ​​lining 25 through the grooves at the bottom. The bottoms of the two linings are connected by the lining connecting plate 5. The structure is simple and stable, easy to disassemble and assemble, and highly maintainable.

[0025] The removable threshold liner of this invention features a simple structure and is easily disassembled, allowing for quick replacement and improved maintainability. The threshold panel is made of FRP, a composite material, to achieve surface insulation. Diamond or corundum is applied to the surface of the threshold panel to enhance wear resistance and increase surface roughness for anti-slip performance. The guide shoe mounting frame 27 is made of steel or aluminum to provide strength for guiding the sliding door, while the slide bars 210 attached to each side of the guide shoe mounting frame 27 provide wear resistance and insulation. The gap compensation device 28 is lined with steel and welded nuts and covered with vulcanized rubber, providing support strength for the interface where the gap compensation device 28 is installed. The front of the rubber strip is comb-shaped to minimize damage to the vehicle body in the event of a scratch. The column insulation block is installed on the steel pipe surface of the column, isolating the column steel structure from the threshold liner structure, thereby breaking the electrical connection between the column and the threshold. The door body and column edges are sprayed with surface insulation. In the event of insulation failure in a local area, it can still provide a certain degree of insulation protection in the area accessible to the public, thereby improving safety performance.

[0026] The present invention solves the insulation problem of platform door thresholds by surface insulation, achieving good insulation effect, high anti-slip performance on the threshold surface, simple structure, and easy maintenance. The present invention uses non-metallic composite materials as the base material for the threshold panel, completely insulating the threshold panel and improving the reliability of the threshold insulation performance. Sandblasting the surface of the threshold panel further improves the threshold's wear resistance and anti-slip performance. The connection between the threshold panel and the lining is optimized, and a removable threshold lining is innovatively added to simplify the structure, facilitate maintenance and replacement, and improve maintainability. The use of composite materials reduces the overall weight of the steel structure compared to traditional solutions, meeting lightweight design and green environmental protection requirements.
