Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit facilities, and particularly relates to a support device for a subway screen door. Background Art

[0002] The subway platform screen door is supported and driven during the opening and closing movement process through a support device arranged on the fixed door. At present, when this device realizes the closing of the screen door, it can only apply force in the sliding direction of the door body relative to itself. Therefore, it can only achieve sufficient pressing between two door bodies, but the door body cannot receive the force perpendicular to the fixed door, resulting in an insufficient sealing effect between the edge of the screen door and the fixed door. When the high-pressure air flow caused by the approaching train impacts, it will pass through the gap, thus generating noise. At the same time, when the air flow passes through the gap, it will cause the vibration of the door body, thus causing damage to the door body. Summary of the Utility Model

[0003] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

Detailed implementation manners

[0022] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0023] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0025] Furthermore, the present utility model is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present utility model, for the sake of convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0026] Referring to Figure 1 , an embodiment of the present utility model provides a subway platform screen door support device, including a force application element (not shown in the figure), and the force application element can adopt a cable drive mechanism. In addition, the device further includes the following parts:

[0027] The force application part 1 is used to be arranged on the platform screen door (hereinafter referred to as the door body) and is used to receive the lateral (referring to the door opening and closing direction) driving force applied by the force application element when opening and closing the door.

[0028] The pushing assembly 2 is used to be arranged on the door body and is used to apply a force to the fixed door or the building body.

[0029] Among them, the pushing component 2 and the force application part 1 are in linkage cooperation. Specifically, when the force received by the force application part 1 itself reaches a certain degree, the pushing component 2 synchronously acts, so as to apply force to the fixed door and the building body, so that the door body receives a reaction force to tightly press against the fixed door;

[0030] Based on the above, when the force application part 1 is installed in the present utility model, the force application part 1 is connected to the force application element. For example, when the force application element adopts a cable drive mechanism, the force application part 1 can be connected to the cable. When the cable moves, it drives the force application part 1 to move, so as to drive the door body to move horizontally to realize the opening and closing actions of the door body. During the process that the force application part 1 is stressed and drives the door body to close, when the two door bodies are closed in place, they can no longer move. At this time, since the force application part 1 cannot move, when it continues to be stressed, its own stress level will reach a certain degree, so that the pushing component 2 applies a pushing force to the fixed door and the building body, that is, the door body receives a reaction force, so as to tightly press against the fixed door, so that the edge of the door body is in full contact with the fixed door, thus effectively improving the sealing effect when closing, reducing the sound caused by the intrusion of high-pressure air flow, and effectively reducing the vibration received by the door body, thus playing a role in protecting the door body;

[0031] As above, when the door body realizes the opening action, the force application part 1 is subjected to a lateral force application effect opposite to the closing direction, so that the two door bodies move away from each other. During this process, the movement of the door body is not blocked, the force application part 1 will not reach the stress limit, and the pushing component 2 stops acting. Therefore, the pushing component 2 only acts when the door body is tightly closed and the force application element keeps applying force.

[0032] Further, referring to Figure 2 and Figure 3 , the pushing component 2 includes a contact plate 201 movably arranged on the door body and an airbag pad 202 arranged on the door body. Specifically, the airbag pad 202 contacts the contact plate 201. An installation groove is formed at the end of the door body. The contact plate 201 and the airbag pad 202 are both located in the installation groove. When the force application part 1 is stressed in place, the airbag pad 202 is filled with gas, so as to squeeze the contact plate 201 to move. The contact plate 201 contacts the fixed door and the building body during the movement process.

[0033] Further, referring to Figure 1 , regarding the way that the contact plate 201 contacts the fixed door and the building body, specifically, the present utility model further includes guide grooves 3 respectively arranged on the fixed door and the ground. One end of the contact plate 201 is located in the guide groove 3. Normally, there is no mutual force between the contact plate 201 and the guide groove 3. When the airbag pad 202 bulges, it squeezes the contact plate 201, so that when the contact plate 201 moves, a mutual force is formed between its end and the inner wall of the guide groove 3, so that the door body receives a reaction force.

[0034] Further, referring to Figure 2 and Figure 4 , the force - applying part 1 includes a cylinder barrel 101 fixed on the door body and a piston 102 arranged in the cylinder barrel 101. The piston 102 is used to receive the driving force applied by the force - applying element. For example, it can be connected to a rope. A first spring assembly 103 is connected between the piston 102 and the cylinder barrel 101. When in the normal state, the piston 102 does not compress the space in the cylinder barrel 101. The cylinder barrel 101 is communicated with the air - bag pad 202. Specifically, it can be connected through a pipeline, and the pipeline can be arranged in the door frame of the door body. When the piston 102 is subjected to force and the door body is not tightly closed, there is no resistance during the movement of the door body, and the door body can move. At this time, the whole formed by the piston 102 and the cylinder barrel 101 is not fully squeezed between the door body and the force - applying element, that is, the space in the cylinder barrel 101 is not compressed, and the air - bag pad 202 cannot bulge. When the door body moves to be tightly closed, the door body cannot move, and the whole is fully squeezed, so that the space in the cylinder barrel 101 is fully compressed by the piston 102, and the air - bag pad 202 bulges, thereby squeezing the contact plate 201 to act.

[0035] Further, referring to Figure 1 , to ensure that during the horizontal sliding installation of the door body, it can still perform a small - amplitude movement in the vertical direction relative to the fixed door when receiving a reaction force. Therefore, the present invention further includes a chute 4 arranged on the ground and a connecting part 5 slidably connected to the fixed door. Specifically, the width of the chute 4 is slightly larger than the thickness of the lower end of the door body. The lower end of the door body is located in the chute 4, so that its lower end can move in the chute 4. The upper end of the door body is movably connected to the connecting part 5. When the connecting part 5 slides horizontally, it can drive the door body to move horizontally. The movable connection between the upper end of the door body and the connecting part 5 and the movable setting of the lower end enable the door body to move a certain distance in the vertical direction of the fixed door when moving horizontally.

[0036] Further, referring to Figure 5 , the connecting part 5 includes a slider 501 and a connecting block 502. The slider 501 is responsible for maintaining a sliding fit with the fixed door, and the connecting block 502 is responsible for maintaining a fixed connection with the door body. A load - bearing end 502a is constructed on the connecting block 502. The load - bearing end can be designed as a column. The weighing end movably penetrates through the slider 501, and a second spring assembly 503 is connected between the connecting block 502 and the slider 501, so as to ensure that the connecting block 502 and the slider 501 can perform elastic activities, that is, to realize the movable connection between the door body and the whole connecting part 5. Through the elastic setting here, it can also ensure that when the door body moves normally, it can maintain a certain distance from the fixed door to prevent excessive tight fitting and resistance during the movement of the door body.

[0037] It should be understood that in the development of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without undue experimentation, such development efforts will be routine work of design, manufacture, and production.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
