Detailed Description
Example 1
Embodiment 1 provides a floor-mounted driven high-speed rail platform door, as shown in fig. 1 to 6, including a plurality of movable door unit groups 100 continuously arranged along a platform direction, each movable door unit group 100 including a first movable door 101, a second movable door 102, a third movable door 103, and a fourth movable door 104 sequentially arranged in a closed state;
the first movable door 101 and the third movable door 103 are arranged on the rear row, namely the track side, and the second movable door 102 and the fourth movable door 104 are arranged on the front row, namely the platform side;
as shown in fig. 3 to 4, the first movable door 101 driving device 201 and the third movable door 103 driving device 203 are disposed at the bottom of the front row and staggered up and down, and the second movable door 102 driving device 202 and the fourth movable door 204 driving device 204 are disposed at the bottom of the front row and staggered up and down.
For example, as shown in fig. 4, the first movable door 101 driving device 201 is disposed at the lower rear row, the second movable door 102 driving device 202 is disposed at the lower front row, the third movable door 103 driving device 203 is disposed at the upper rear row, and the fourth movable door 104 driving device 204 is disposed at the upper front row. Alternatively, the first movable door 101 driving device 201 is disposed at the lower rear row, the second movable door 102 driving device 202 is disposed at the upper front row, the third movable door 103 driving device 203 is disposed at the upper rear row, and the fourth movable door 104 driving device 204 is disposed at the lower front row. Those skilled in the art will understand that: the driving devices of the front row of movable doors and the rear row of movable doors are staggered front and back, and the movable doors at intervals in the same row are staggered up and down. Thus, the independent driving of 4 movable doors in each movable door unit group 100 is realized, and the respective driving devices do not interfere with each other. Based on the above concept, one movable door unit group consists of 4 frame movable doors, and if a movable door is added to each movable door group, a driving device needs to be added in the depth direction, so that an overlarge space below the platform ground is occupied; if two sliding doors form a unit group, more sliding door unit groups 100 need to be coded and controlled, which results in a reduction in control efficiency. In addition, every 4 movable doors are grouped, and the shared structural components can be grouped as units for prefabrication and assembly on site during construction, so that the structural stability and the construction efficiency are considered.
The first movable door 101 and the fourth movable door 104 are configured to be movable by 1 or 2 movable door widths toward the central position of the movable door unit group in which the movable door is located under the driving of the driving device; that is, the first movable door 101 may be parked at the positions of the first, second and third movable doors 101, 102 and 103 in the platform door closed state, and the fourth movable door 104 may be parked at the positions of the second, third and fourth movable doors 102, 104 and 104 in the platform door closed state.

Fig. 7-13 are schematic views of various door-opening states formed by two adjacent movable door unit groups. The width of each two movable doors corresponds to one opening width. When the front row of movable doors and the rear row of movable doors are overlapped, the movable door with the upper serial number is the front row of movable doors, and the movable door with the lower serial number is the rear row of movable doors.
In fig. 7, the first movable door 101 of the left movable door unit group 100 moves 2 positions to the right and overlaps the second movable door 102 moving 1 position to the right, and the door moving 1 position to the right overlaps the fourth movable door 104 to form a door opening scene 1.
In fig. 8, the second movable door 102 of the left movable door group 100 moves 1 position to the left to overlap with the first movable door 101, and the third movable door 103 moves 1 position to the right to overlap with the fourth movable door 104 to form a door opening scene 2.
In fig. 9, the second movable door 102 of the left movable door group 100 is moved 1 position to the left to overlap the first movable door 101, and the third movable door 103 is moved 1 position to the left to overlap the fourth movable door 104 moved 2 positions to the left to form the door opening scene 3.
In fig. 10, the fourth movable door 104 of the left movable door group 100 moves 1 position to the left to overlap with the third movable door 103, and the first movable door 101 of the right movable door group 100 moves 1 position to the right to overlap with the second movable door 102 thereof to form the door opening scene 4.

The guide slider 411 is a slider with an upper portion concave, the guide rail is a guide rail with a lower portion convex, and the upper end of the guide rail is fixed on the bottom surface of the platform ground layer. The slide block and the guide rail in the shape can lead the guidance to be more stable and transfer partial load of the platform door to the platform ground layer.
The bottom space includes a platform side space and a track side space; the driving device of the movable door in the row at the platform side is arranged at one side of the platform side space close to the track, and the driving device is connected with the tail end of the bending part of the guide plate, so that the thickness of the bottom space of the platform door in the direction vertical to the platform can be reduced.
The driving device of the movable door in the row at the track side is arranged at one side of the track side space close to the track, and the driving device is connected with the tail end of the vertical section of the guide plate.
Each movable door adopts an independent driving device; the driving device is arranged at the bottom of the movable door and comprises a driving motor, a driving gear driven by the driving motor, a synchronous belt connected with the driving gear and a driven wheel connected with the synchronous belt. The driving motor can select a servo motor, and the moving distance of the movable door can be ensured to meet the precision requirement by the transmission mode of the gear matched with the synchronous belt. The movable door is connected with a synchronous belt of the driving device through a connecting rod.
The bottom space is constructed by embedding a steel structure. The mode that adopts the pre-buried steel construction subassembly in bottom between platform ground and the dodge gate can provide platform door installation effectiveness or the efficiency of existing platform door transformation to and the stability of platform door use.
Guide wheels capable of rolling along the ground are arranged at two ends of the guide plate 410 at the lower part of the movable door body.
The lower part of the bottom space of the platform door is an inclined plane facing the track side, so that the platform door is convenient for drainage.
