[0056] Referring to Figures 1 to 11 As shown, the present application provides a high-strength modular fully-enclosed platform door system, which comprises a steel structure module 1 and a door body module 2. The steel structure module 1 comprises a plurality of top connecting devices 11 and a plurality of columns 12, each of the top connecting devices 11 is used to be connected to a civil beam 7, and each of the columns 12 is used to be connected to a civil platform 8, the column 12 has a top slot, and the top connecting device 11 has a plug 113, the plug 113 of each top connecting device 11 is respectively and slidably plugged into the top slot of the corresponding column 12, and the door body module 2 is arranged on the steel structure module 1.

[0057] The top of the steel structure module 1 of the high-strength modular fully-enclosed platform door system of the present application is directly connected to the civil beam 7, and the bottom is directly connected to the civil platform 8, so that the stress of the wind pressure load, the crowd extrusion load and the like borne by the system is transmitted to the civil structure to ensure the overall stability.

Through the fully-enclosed design, the influence of the "train wind" on the passengers is reduced, and the riding comfort is improved.

[0058] The high-strength modular fully-enclosed platform door system of the present application extends along the entire civil platform 8 and is connected to the civil beam 7 and the civil platform 8 respectively at the top and the bottom, realizes the fully-enclosed design, isolates the platform and the track area, blocks the exchange of cold and hot air, reduces the air conditioning load, has energy saving and environmental protection, improves the comfort of passengers, and saves energy.

[0059] In some possible embodiments, in order to improve the space utilization rate of the platform, the steel structure module 1 can be installed close to the platform edge, thereby maximizing the saving of the platform area, improving the space utilization efficiency, reducing the civil cost of the station, and improving the economic benefits.

[0060] In some possible embodiments, the column 12 comprises a tube body having a tube cavity and a tube opening communicating with the tube cavity, and a gasket 121 connected to the tube body and covering the tube opening, the gasket 121 having the top slot communicating with the tube cavity. The gasket 121 can be made of metal material and welded to the column 12, and the inner diameter of the top slot on the gasket 121 matches the outer diameter of the bolt 113, so as to avoid the column 12 from shaking in the horizontal direction relative to the top connecting device 11.

[0061] In some possible embodiments, the top connecting device 11 comprises an upper connecting piece 111 and a lower connecting piece 112, the upper connecting piece 111 being used to connect and fix with the civil beam 7, and the lower connecting piece 112 being connected to the upper connecting piece 111 and movable and fixable relative to the upper connecting piece 111 in a plane perpendicular to the column 12, and the bolt 113 being arranged on the lower connecting piece 112.

[0062] The upper connecting piece 111 and the lower connecting piece 112 realize the relative movement in the horizontal plane, and can be adjusted in the X direction and the Y direction, so as to absorb the error of the civil structure, facilitate the assembly, reduce the assembly requirement, and improve the assembly efficiency.

[0063] In some possible embodiments, the upper connecting piece 111 has a first plate body 1111 and a second plate body 1112, the first plate body 1111 and the second plate body 1112 being connected vertically, the first plate body 1111 being provided with a first slot 11111 for being connected to the civil beam 7 by a fastener, the second plate body 1112 being provided with a plurality of second slots 11121, the lower connecting piece 112 being provided with a third slot, and any two of the first slot 11111, the second slot 11121 and the third slot being perpendicular, and a plurality of fasteners being respectively arranged in the opposite second slot 11121 and the third slot, so as to connect the second plate body 1112 and the lower connecting piece 112. The fastener can be a bolt.

[0064] The first slot 11111 is arranged, so as to realize the position adjustment of the top connecting device 11 in the Z direction. The application realizes the adjustment function in the three-dimensional space by arranging the slots in three directions on the upper connecting piece 111 and the lower connecting piece 112, so as to absorb the error of the civil structure.

[0065] The column 12 can include a tube (steel tube) and an elongated rod welded by a steel plate, and the column 12 bottom plate can be bolted to the civil platform 8. The column 12 top is connected to the top connecting device 11 to form an integral whole, and a simply supported beam model is formed in the structure stress to ensure the stiffness and strength of the steel structure. The top connecting device 11 and the column 12 structure top are reserved with space, and when the civil beam 7 naturally settles, the overall steel structure is not affected. See Figure 2 As shown, along the platform edge, the column 12 is vertically arranged at the required interval, and the column 12 and the column 12 gap are installed with the transverse lintel structure 13 and the door sill structure 14.

The fixed door separates the public area of the platform from the tunnel area. The emergency door 23 is provided at the fixed area position and adopts a vertical hinged door form. It is locked when it is closed in normal operation and separates the public area from the track area. When the train cannot be aligned with the sliding door 22 when entering the station, it can be used as an emergency evacuation channel for passengers. In order to meet the design strength and stiffness requirements of large wind pressure and large load without permanent deformation, the door body module 2 is made of homogeneous tempered safety glass and door frame skeleton structure by adhesive bonding. In order to improve the air tightness of the system and block the exchange of cold and hot air, the door body is filled with sealant, rubber and other materials around the door body.

[0067] Each sliding door 22 is provided with a locking device and an unlocking device. The sliding door 22 is provided with a manual unlocking handle on the track side and a key unlocking switch on the platform side. When the system level control and the platform level control fail (such as power supply or control system failure, the door cannot be automatically opened), passengers can manually open the door from the track side, and staff can manually open the door from the platform side with a key. The locking device is automatically released when the sliding door 22 is automatically opened, and the locking device can be manually unlocked by the door handle or key in case of failure. The locking device reliably locks the sliding door 22 after the sliding door 22 is closed, and the locking device can also report a locking signal and effectively unlock in case of power failure.
