Both the first folding plate 11 and the second folding plate 21 are C-shaped. At least a portion of the driving member 12 is located within the space enclosed by the first folding plate 11, and at least a portion of the first slide rail 13 is located within the space enclosed by the second folding plate 21. A pull rope is connected to the slider, so that the platform gate body formed by the pull rope moves up and down with the second folding plate and the slider. Both the first slide rail 13 and the second slide rail 23 are vertically extending slide rails.

[0031] In this utility model, the fixed part 1 is a fixed column installed on the platform ground, and the movable part 2 is a structure that lifts and lowers on the fixed part 1. The movable part 2 is equipped with a slider 22, and a platform door pull rope is connected to the slider 22. The two platform door columns and the platform door pull rope between them form a platform door structure. Unlike conventional columns, the main body of the fixed part 1 and the movable part 2 in this application are both folded plate parts. The main body of the fixed part 1 is the first folded plate part 11, and the main body of the movable part 2 is the second folded plate part 12, which is used to drive the movable part 2 to lift and lower. The driving component 12 is located within the space enclosed by the first folding plate 11, while the first slide rail 13, which connects the fixed part 1 and the movable part 2, is located within the space enclosed by the second folding plate 21. This reduces the space required for the installation of the driving component 12 and the slide rail, making the entire platform door column thinner and occupying less space. Furthermore, the structure of the folding plate still ensures the overall strength of the fixed part 1 and the movable part 2. The platform door column can be safely and stably installed outside the tactile paving without interfering with it. In other words, the platform door column can be added based on the existing platform structure plan.

[0032] Specifically, the first folding plate part 11 of the fixed part 1 comprises two first side plates 112 which are substantially parallel and a first main plate 111 for connecting the two first side plates 112, the driving part 12 is located between the two first side plates 112, in fact, the driving part 12 is a driving motor and is located at the top end of the first main plate 111, the motor is connected with the movable part 2 through a chain 15, and the motor drives the movable part 2 to ascend and descend; the second folding plate part 21 of the movable part 2 comprises two second side plates 212 which are substantially parallel and a second main plate 211 for connecting the two second side plates 212, and at least a part of the first slide rail 13 is located between the two second side plates 212, the second side plate 212 is connected with the first slide rail 13, and the sliding of the movable part 2 is limited.

[0034] Before the platform door is opened, the second folding plate part 21 is the same in height as the first folding plate part 11, and the second folding plate part 21 is located at the side of the first folding plate part 11; when the platform door is opened, the second folding plate part 21 as a whole rises along the first slide rail 13, the sliding block 22 rises along the second slide rail 23 on the second folding plate part 21, the pull rope on the sliding block 22 is lifted, and the passenger is facilitated to get on and off the train.

[0035] In this way, the space for installing the driving part 12 and the slide rail is reduced, the whole platform door stand column is thinner, and the thickness can reach 20 cm; a safety white line is arranged on the side close to the platform edge of a general blind line, and the safety white line is 0.6 meters away from the platform edge; after the platform door column of the utility model is installed, the platform door column is arranged close to the safety white line, that is, the use of the blind line is not affected, the outside of the platform door column is still 40 cm away from the platform edge, is not affected by the wind force of high-speed rail entering the station, and the space for emergency escape can still be reserved.

[0036] Embodiment two, still as Figs. 1 to 4As shown, only one embodiment of the utility model, in the embodiment on the basis, the utility model discloses a folding plate type platform door stand column structure, the driving shaft 14 of drive piece 12 is engaged with chain 15, one end of chain 15 is connected with second folding plate piece 21, the one end of chain 15 away from second folding plate piece 21 is connected with counterweight 16, drive piece 12 is motor, and driving shaft 14 is motor shaft, and the outside of motor shaft is provided with gear, and the middle part of chain 15 is engaged with gear, and the both ends of chain 15 are connected to second folding plate piece 21 and counterweight 16 respectively, at least a part of counterweight 16 is located between two first side plates 112, and second folding plate piece 21 is arranged on the side of first main plate 111 away from first side plate 112, when motor drives motor shaft to rotate and drives second folding plate piece 21 to rise, counterweight 16 will descend to compensate gravity, and the motor with smaller output power can drive second folding plate piece 21 to rise, and the opening of safety door is completed.

[0037] The first sliding rail 13 is located on the side of the first main plate 111 away from the drive piece 12, and the number of the first sliding rail 13 is two;A connecting block 17 is arranged between the two first sliding rails 13;The side of the first sliding rail 13 away from the connecting block 17 is connected with the second side plate 212.

[0038] In the utility model, the second folding plate piece 21 includes two substantially parallel second side plates 212 and a second main plate 211 for connecting the two second side plates 212, at least a part of the first sliding rail 13 is located between the two second side plates 212, and the second sliding rail 23 is located on the side of the second main plate 211 away from the second side plate 212.

[0039] In addition, the second main plate 211 is provided with a rotating roller 24 and a connecting belt 25 connected with the rotating roller 24, one end of the connecting belt 25 is connected with the connecting block 17, the end of the connecting belt 25 away from the connecting block 17 is connected with the sliding block 22, the middle part of the connecting belt 25 is connected with the rotating roller 24, the rotating roller 24 is equivalent to a fixed pulley, and the both ends of the connecting belt 25 are connected to the connecting block 17 and the sliding block 22 respectively, so that when the second folding plate piece rises along the first sliding rail, the connecting belt 25 pulls the sliding block 22 to rise along the second sliding rail 23.

[0040] That is to say: when the second folding plate piece 21 (and the rotating roller 24) rises, the position of the connecting block 17 fixed on the first folding plate piece 11 does not change, that is, the connecting block 17 "descends" relative to the rotating roller 24, so that the sliding block 22 located on the side of the rotating roller 24 away from the connecting block 17 rises relative to the second folding plate piece 21 (the rotating roller 24), so that the sliding block 22 and the pulling rope on the sliding block 22 further rise, and the opening of the safety door is completed.

[0041] The sliding block 22 is provided with a pull rope connecting buckle 221 for connecting with the pull rope, and the end of the pull rope of the safety door is connected to the pull rope connecting buckle 221.

[0042] Here, the number of the sliding blocks 22 is at least two, and there are multiple pull ropes between the two platform door stand columns, the multiple parallel pull ropes form the door body structure of the safety door, a connecting rope is arranged between the two adjacent sliding blocks 22, and the connecting rope is connected with the lowermost sliding block 22.

[0043] Therefore, when the safety door is lowered, the connecting rope is pulled straight under the gravity, and the distance between the multiple sliding blocks 22 is the length of the connecting rope; when the safety door is raised, the connecting rope overcomes the gravity of the sliding blocks 22 and pulls all the sliding blocks 22 upward.

[0044] Finally, the first folding plate member 11 and the second folding plate member 21 are integrally formed members, the integrally formed members are stable in structure and convenient to prepare, the first folding plate member 11 and the second folding plate member 21 are good in stability and can effectively support the safety door structure.
