Description

Technical Field

[0001] The embodiments of the present application relate to the field of rail transit technology, and in particular to a blocking device and a high-speed railway platform safety screen door. Background Art

[0002] In recent years, with the continuous progress of urbanization, urban traffic pressure has become increasingly greater, resulting in more and more cities choosing to use rail transit to alleviate the necessary traffic pressure. The urban rail transit system refers to a transportation system that uses vehicles to run on fixed rails in the city and is mainly used for urban passenger transportation. On the platform of urban rail transit, passengers often wait on the platform before the train enters the station, and the number of passengers is often large. It is easy to cause safety accidents due to crowded platforms. In order to prevent passengers from falling from the platform, it is necessary to install safety screen doors on the platform. After the train enters the station and stops, the safety screen doors will be opened to allow passengers to get on and off the train.

[0003] In order to prevent the occurrence of the above situation, the high-speed railway platform safety shield door in the prior art includes a rolling curtain that can be folded or unfolded, and a number of LED light strips are installed on the surface of the rolling curtain. Before the train enters the station, the rolling curtain is unfolded and the LED light strip is turned on. The strong warning light emitted by the LED light strip is used to warn passengers waiting on the platform to prevent passengers from approaching the gap between the platform and the train, thereby preventing safety accidents of passengers falling.

[0004] However, the high-speed railway platform safety screen doors in the prior art use soft material such as rolling curtains. When passengers are crowded, the rolling curtains are easily damaged after being subjected to force and cannot effectively block the passengers, resulting in the disadvantage that passengers may fall onto the track in the gap between the platform and the train and cause unexpected safety accidents.

[0041] Example 1

[0042] As a basic implementation of the utility model, Figure 1 , 3A blocking device as shown in Figure 4 comprises a mounting frame 2, the mounting frame 2 comprises a first mounting plate 21 and a second mounting plate 23 which are arranged opposite to each other, the mounting frame 2 is used to install components such as a guide portion 5 and a scissor-type connecting rod mechanism 6; a guide portion 5, the guide portion 5 is arranged between the first mounting plate 21 and the second mounting plate 23, and both ends of the guide portion 5 are respectively fixedly connected to the first mounting plate 21 and the second mounting plate 23; a plurality of connecting portions 4, the plurality of connecting portions 4 are arranged on the guide portion 5 and are respectively slidably matched with the guide portion 5, that is, the connecting portions 4 can slide on the guide portion 5 along the direction of the guide portion 5; a plurality of blocking portions 1, the plurality of blocking portions 1 are correspondingly arranged on the plurality of connecting portions 4, that is, when the connecting portions 4 slide, the blocking portions 1 can be driven to move;

[0043] The scissor-type linkage mechanism 6 is arranged between the first mounting plate 21 and the second mounting plate 23, and one end of the scissor-type linkage mechanism 6 is fixedly connected to the first mounting plate 21. The scissor-type linkage mechanism 6 includes a plurality of intersecting units 61 hinged to each other in sequence, and a plurality of connecting parts 4 are correspondingly arranged on the plurality of intersecting units 61. The scissor-type linkage mechanism 6 is composed of a plurality of intersecting units 61 hinged to each other in sequence, so that the scissor-type linkage mechanism 6 can be extended and retracted under the action of an external driving force, and the plurality of connecting parts 4 can be driven to move when the scissor-type linkage mechanism 6 is extended and retracted by correspondingly connecting the plurality of connecting parts 4 with the plurality of intersecting units 6.

[0044] At the same time, in order to facilitate the design of the overall device structure, the guide portion 5 and the scissor-type connecting rod mechanism 6 are respectively and sequentially arranged between the first mounting plate 21 and the second mounting plate 23;

[0045] The driving mechanism 7 is arranged on the scissor-type linkage mechanism 6. The driving mechanism 7 includes a screw rod 72. The two ends of the screw rod 72 are respectively rotatably matched with the first mounting plate 21 and the second mounting plate 23, that is, the two ends of the screw rod 72 rotate relative to the first mounting plate 21 and the second mounting plate 23; a screw nut 73, the screw nut 73 is arranged on the screw rod 72, and the screw nut 73 is threadedly matched with the screw rod 72, that is, when the screw rod 72 rotates, the screw nut 73 can be driven to move on the screw rod 72 along the direction of the screw rod 72; one end of the screw nut 73 is connected to the cross unit 61; a driving motor 71, the driving motor 71 is connected to one end of the screw rod 72 That is, the driving motor 71 drives the screw rod 72 to rotate. Since the screw nut 73 is threadedly matched with the screw rod 72, when the screw rod 72 rotates, the screw nut 73 can be driven to move on the screw rod 72 along the direction of the screw rod 72. Since the screw nut 73 is connected to the cross unit 61, when the screw nut 73 moves, the scissors-type linkage mechanism 6 can be driven to extend and retract. At the same time, since multiple connecting parts 4 are connected to multiple cross units 6, multiple blocking parts 1 are connected to multiple connecting parts 4, and multiple connecting parts 4 are slidably matched with the guide parts 5, the extension and retraction of the scissors-type linkage mechanism 6 can drive the multiple blocking parts 1 to expand or retract along the extension and retraction direction of the scissors-type linkage mechanism 6.

First, the scissor-type linkage mechanism 6 is composed of a plurality of mutually hinged cross units 61, so that the scissor-type linkage mechanism 6 can be extended and retracted, and the connecting part 4 is correspondingly installed on the cross unit 61, one end of the scissor-type linkage mechanism 6 is fixedly connected to the first mounting plate 21, the driving mechanism 7 is connected to the scissor-type linkage mechanism 6, and a blocking part 1 is further provided on the connecting part 4, and the connecting part 4 is slidably matched with the guide part 5. In this way, when the driving mechanism 7 drives the scissor-type linkage mechanism 6 to extend and retract, the scissor-type linkage mechanism 6 can drive the connecting part 4 connected to the cross unit 61 to slide along the guide part 5, and further drive the connecting part 4 The connected blocking portion 1 moves along the telescopic direction of the scissors-type connection mechanism 6, thereby being unfolded (i.e., the blocking portion 1 moves downward along the telescopic direction of the scissors-type connection mechanism 6 until the scissors-type connection mechanism 6 is in a fully extended state) and folded (i.e., the blocking portion 1 moves upward along the telescopic direction of the scissors-type connection mechanism 6 until the scissors-type connection mechanism 6 is in a fully retracted state). Before the train enters the station, the blocking portion 1 is unfolded, and the blocking portion 1 can withstand a certain force, so when the blocking portion 1 is in the unfolded state, it can effectively block passengers when passenger congestion occurs, preventing passengers from falling onto the track in the gap between the platform and the train and causing unexpected safety accidents.

[0070] First, the lifting device 200 drives the blocking device 100 to rise to a certain height, and then the blocking device 100 works to put the blocking part 1 in a retracted state (that is, first the motor 71 is driven to drive the screw rod 72 to rotate relative to the first mounting plate 21 and the second mounting plate 23. When the screw rod 72 rotates, it can drive the screw nut 73 to move upward along the direction of the screw rod 72.
