Description

Technical Field

[0001] The utility model relates to the field of rail transportation, in particular to a running structure on a platform plate. Background Art

[0002] Full-height platform doors, as public safety devices, are widely used on elevated and underground platforms of subways, light rail, intercity railways, and other rail transit systems. They offer energy-saving, environmentally friendly, and safety features. Installed along the platform edge, they separate the train from the platform waiting area. Installing a safety door system not only prevents passengers from falling or jumping onto the tracks and causing danger, but also shortens boarding and alighting times, ensuring orderly and convenient boarding and alighting for passengers, thereby improving operational efficiency. Currently, full-height platform doors primarily feature two support and travel mechanisms.

[0003] The first structure uses columns fixed to the platform. Each sliding door unit requires two columns. A guide rail assembly is installed above the columns. The sliding door is hung on the guide rail via a suspension device, and the lower part is restrained by the cooperation of the guide shoe and the threshold seam. The columns primarily serve as the support structure of the fully shielded safety door system to maintain the stability and safety of the door body. During the design and installation of the fully shielded door, the columns must be precisely positioned according to design requirements, the positioning plate must be set, and basic connection work must be carried out to ensure that they will not deform or collapse when subjected to the weight of the door body and various forces during use. At the same time, they must also meet certain structural strength and stability requirements. Although this structure also applies the weight of the door body to the platform, it cannot be installed on the entire platform side due to the obstruction of the columns. As a result, not only is the construction cumbersome, but there are also problems such as the difficulty of installing sliding doors continuously on the platform side.

[0004] The second design secures the upper support assembly to the upper civil engineering beam, then installs the guide rail assembly on top. The sliding door is then hung on the rail via a suspension device, with the lower portion secured by a guide shoe that fits into the threshold gap. This structure eliminates the columns, making it possible to install sliding doors on the entire platform side. However, all the weight is applied to the upper beam, placing significant stress on it and posing a safety hazard.

[0005] To this end, there is an urgent need for a technical solution that does not require the installation of columns on the platform board, can apply the gravity of the sliding door to the platform board, and can enable the sliding door to move at an unlimited distance, thereby breaking the application barriers of fully shielded safety doors. Utility Model Content

[0006] The utility model provides a running structure on the platform plate, which does not require the installation of columns on the platform plate, thereby ensuring the continuity of the running structure's movement on the platform, while reducing the stress on the upper beam, overcoming the technical barriers to the installation of fully shielded safety doors, and making the running structure stable in operation and prevent overturning, which has important practical significance.

[0007] To achieve the above-mentioned objectives, the utility model provides a running structure on a platform plate, wherein the running structure includes one or more bottom running support assemblies, running limit guide grooves, upper guide rail assemblies and / or upper support assemblies; the bottom running support assembly is connected to the platform plate, and the running limit guide grooves are installed on the bottom running support assembly; the upper support assembly is fixed on the platform, and the upper guide rail assembly is installed on the upper support assembly; the running structure moves along the X-axis direction in the running limit guide grooves, and the movement in the Y-axis and / or Z-axis directions is limited; the running structure moves along the X-axis direction of the upper guide rail assembly, and the rotation in the X-axis direction is limited.

[0008] The running structure provided by this utility model not only eliminates the need for columns installed on the platform board, as is required for traditional platform doors, but also allows the sliding door to run on the platform board, moving an unlimited distance along the X-axis, thereby allowing the entire side of the platform to be configured as a sliding door. At the same time, the gravity of the running structure can be applied to the platform board, reducing the stress on the upper beam and overcoming the current installation barriers of fully shielded platform safety doors. Furthermore, the technical solution provided by this utility model limits the movement of the sliding door in the Y- and Z-axis directions and prevents the sliding door from tipping over under stress, thereby resolving a significant technical issue plaguing the installation and use of fully shielded safety doors in the rail transit industry.

[0028] In the running structure provided by the present invention, the running limit guide groove 3 is installed on the bottom running support assembly 2, the upper support assembly 6 is fixed to the platform, and the upper guide rail assembly 5 is installed on the upper support assembly 6. The running structure moves along the X-axis in the running limit guide groove 3, and its movement in the Y-axis and / or Z-axis directions is limited.

The top screw 6c is connected to the upper L-shaped bracket 6a through threaded engagement and supports the civil engineering connecting plate 6b. The top screw 6c can be rotated with a wrench to adjust the size of the upper support assembly 6 in the Z-axis direction.

[0035] The bottom support plate 2b of the bottom running support assembly 2 is connected to the platform plate by fixing anchor bolts 1, and the adjustment gasket 2a is filled between the bottom support plate 2b and the platform plate. By changing the number and thickness of the adjustment gasket 2a, the height of the bottom running support assembly 2 in the Z-axis direction can be adjusted. A waist hole is opened in the bottom support plate 2b along the Y-axis direction so that the bottom support plate 2b can be appropriately adjusted along the Y-axis direction. A waist hole is opened in the track mounting plate 2c along the X-axis direction and connected to the bottom support plate 2b by bolts so that the track mounting plate 2c can be appropriately adjusted along the X-axis direction. This realizes the three-dimensional adjustment of the running limit guide groove 3 installed on the bottom running support assembly 2 in the X, Y, and Z axis directions.

[0036] Therefore, the three-dimensional adjustment of the running structure provided by the utility model in the X, Y and Z axis directions is achieved.
