Technical Field

[0001] This utility model belongs to the technical field of subway platform screen door, and relates to a subway platform screen door top box cover plate, and more particularly to a subway platform screen door top box cover plate and a subway platform screen door maintenance structure. Background Technology

[0002] The subway platform screen door system is a core piece of equipment for ensuring passenger safety and improving operational efficiency. Subway platform screen doors consist of a door frame and sliding doors connected to the frame. Various key components, such as integrated drive motors, control modules, transmission mechanisms, and cables, are concealed within the frame. Covers are fixed to both the inner (track side) and outer (platform side) sides of the frame. The track-side cover is fixed and cannot be opened after installation, while the platform-side cover is movable and can be disassembled to expose the internal components for maintenance.

[0003] To ensure high-reliability sealing of the entire system and prevent dust and humid air from the track side from entering the precision equipment, the top of the gantry is also fixed with a non-openable cover. This cover connects to both the track-side and platform-side cover plates, and multiple sealing structures are installed at the connection points. Therefore, maintenance of the platform screen doors can only be performed by opening the platform-side cover plate. This design results in a limited opening range, making it difficult to access rear or more concealed equipment. Repairing equipment deep within the structure often requires disassembling multiple cover plates, a cumbersome process that can easily compromise the seal. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a subway platform screen door top box cover and a subway platform screen door maintenance structure. It solves the technical problem of difficult maintenance caused by the limited opening space of existing subway platform screen doors.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A subway platform screen door top box cover includes a rear sealing plate and a movable sealing plate. One end of the rear sealing plate has a protruding positioning part for fixing, and the movable sealing plate is connected to the other end of the rear sealing plate opposite to the positioning part, which can be flipped up and down. An elastic element is provided at the connection position between the movable sealing plate and the rear sealing plate. Under the elastic force of the elastic element, the movable sealing plate always maintains an upward rotation tendency. In use, the movable sealing plate can be pulled down to rotate its end to a horizontal position or below the horizontal position.

[0007] The top cover of this subway platform screen door has a separate structure consisting of a rear sealing plate and a movable sealing plate. The rear sealing plate is used to fix the door frame on the track side. After the positioning part of the rear sealing plate is fixed, it forms a seal with the cover plate on the track side. The movable sealing plate can rotate up and down to open the head space of the screen door, which greatly improves the range, angle and depth of the door frame on the platform side that can be opened during maintenance. The opening of the head space allows for maintenance of equipment at greater depths, making operation and maintenance convenient.

[0008] In the aforementioned subway platform screen door top box cover, the movable sealing plate is connected to the end of the rear sealing plate via an elastic hinge. The elastic element is a coil spring inside the elastic hinge, and the movable sealing plate can rotate upward to the open state under the drive of the elastic hinge.

[0009] The movable sealing plate of this application is connected to the rear sealing plate via a flexible hinge. When closing, the movable sealing plate is pulled down to overcome the spring force and close. When maintenance is required, simply remove the movable cover plate pressing on the movable sealing plate, and the movable sealing plate will automatically release and rise. This eliminates the need for disassembly, making it very convenient. Moreover, the automatically rising design of the movable sealing plate ensures that its automatic opening range remains constant, without interfering with personnel operation, further facilitating maintenance.

[0010] In the aforementioned subway platform screen door top box cover, the rear cover plate includes a top cover, an extension, and the aforementioned positioning part, all three being integrally formed. The extension is inclined, and the top cover and the positioning part are located at the highest and lowest points of the extension, respectively.

[0011] The positioning part on the rear cover plate of this application is used to fix it to the door frame. The extension part extends at an angle to raise the height of the top cover. This allows for a larger headroom range when the movable cover plate is connected to the top cover, making maintenance easier. At the same time, the presence of the top cover can shield the door frame on the track side, effectively preventing dust from entering and better protecting the internal equipment.

[0012] In the aforementioned subway platform screen door top box cover, the end of the top cover has a downwardly bent edge, the elastic hinge is fixed to the inside of the bent edge, and the movable sealing plate is located above the elastic hinge with its end portion entering the inside of the bent edge.

[0013] Flexible hinges and other connectors can be hidden under the top cover and movable sealing plate, reducing the exposure of parts when closed and effectively improving sealing performance.

[0014] In the aforementioned subway platform screen door top box cover, a sealing strip is fixed on the end of the movable sealing plate away from the elastic hinge, and the sealing strip covers the outer edge of the movable sealing plate.

[0015] The sealing strip on the end of the movable sealing plate of this application serves to seal the connection position when connected with the movable cover plate on the platform side, ensuring the sealing performance of the platform screen door before and after maintenance.

[0016] In the aforementioned subway platform screen door top cover, the bottom of the sealing strip has a downwardly protruding buffer portion, and the inner side of the buffer portion has a buffer cavity with a triangular outline.

[0017] The buffer section is used to contact the door frame, which serves both as a buffer and a seal. Its built-in buffer cavity deforms along with the sealing strip, and the overall buffer section can fill gaps and enhance sealing performance.

[0018] In the aforementioned subway platform screen door top box cover, the top of the sealing strip extends along the upper surface of the movable sealing plate to form an abutment portion.

[0019] The abutting part at the top of the sealing strip is used to contact the movable cover plate on the platform side to form a seal.

[0020] In the aforementioned subway platform screen door top cover, the opening angle of the movable sealing plate rotating upward is greater than 45°.

[0021] The large-angle opening of the movable sealing plate allows for a larger opening of the head space of the door frame, accommodating more in-depth maintenance work.

[0022] A maintenance structure for a subway platform screen door is disclosed. The subway platform screen door includes a door frame with an inner end near the track and an outer end near the platform. The maintenance structure includes a movable cover plate and a top box cover plate for the subway platform screen door. The positioning part on the rear cover plate is fixed to the inner end of the door frame. The movable cover plate is pulled down to abut against the outer end of the door frame. The upper edge of the movable cover plate presses against the outer edge of the movable cover plate, and the movable cover plate is fixed to the outer end of the door frame by bolts.

[0023] When in use, the positioning part of this top box cover is fixed to the door frame on the track side. The cover on the track side contacts the rear sealing plate at the positioning part to close the track side. The rear sealing plate extends towards the platform side. At the top of the platform door, i.e., at the extended end of the rear sealing plate, there is a movable sealing plate that can be flipped up and down. When the movable sealing plate rotates to a horizontal position or below the horizontal position, it covers the top of the door frame. At the same time, the upper edge of the movable cover on the platform side is bent and hooked onto the end of the movable sealing plate, pressing it against the door frame. Installation is completed simply by fixing the movable cover to the door frame. When maintenance is required, the movable cover is removed, and the corresponding movable sealing plate, no longer obstructed, will rotate upward to open the head space of the platform door. This greatly increases the opening size and depth of the maintenance port, greatly facilitating maintenance.

[0024] In the aforementioned subway platform screen door maintenance structure, the height at which the movable sealing plate connects to the rear sealing plate is higher than the height at which the upper edge of the movable cover plate presses against the outer edge of the movable sealing plate.

[0025] The beneficial effects of this utility model are: when this platform screen door is being maintained, only the movable cover plate on the platform side needs to be removed. The corresponding movable sealing plate will rotate upwards to open the head space of the platform screen door when it is no longer obstructed. This greatly increases the opening size and depth of the maintenance port, which greatly facilitates maintenance. Attached Figure Description

[0029] like Figure 1 and Figure 2The subway platform screen door top box cover shown includes a rear sealing plate 1 and a movable sealing plate 2. One end of the rear sealing plate 1 has a protruding positioning part 13 for fixing, and the movable sealing plate 2 is rotatably connected to the other end of the rear sealing plate 1 opposite to the positioning part 13. An elastic element is provided at the connection position between the movable sealing plate 2 and the rear sealing plate 1. Under the elastic force of the elastic element, the movable sealing plate 2 always maintains an upward rotation tendency. In use, the movable sealing plate 2 can be pulled down to rotate its end to a horizontal position or below the horizontal position. This subway platform screen door top box cover is a split structure of rear sealing plate 1 and movable sealing plate 2. The rear sealing plate 1 is used to fix to the door frame 5 on the track side. After fixing, the positioning part 13 of the rear sealing plate 1 forms a closed joint with the cover plate on the track side. The movable sealing plate 2 can rotate up and down to open the head space of the platform screen door, which greatly improves the range, angle and depth of opening of the door frame 5 on the platform side during maintenance. The opening of the head space allows for maintenance of equipment at greater depths, making operation and maintenance convenient. The subway platform screen door includes a door frame 5, which has an inner end on the side of the track and an outer end on the side of the platform. This maintenance structure includes a movable cover plate 6 and a subway platform screen door top box cover plate as described above. The positioning part 13 on the rear sealing plate 1 is fixed to the inner end of the door frame 5. By pulling down the movable sealing plate 2, it is made to abut against the outer end of the door frame 5. The upper edge of the movable cover plate 6 presses against the outer edge of the movable sealing plate 2, and the movable cover plate 6 is fixed to the outer end of the door frame 5 by bolts. When in use, the positioning part 13 of this top box cover is fixed to the door frame 5 on the track side. The cover on the track side contacts the rear sealing plate 1 at the positioning part 13 to close the track side. The rear sealing plate 1 extends towards the platform side. At the top of the platform door, i.e., at the extended end of the rear sealing plate 1, a movable sealing plate 2 that can be flipped up and down is rotatably connected. When the movable sealing plate 2 rotates to a horizontal position or below the horizontal position, it covers the top of the door frame 5. At the same time, the upper edge of the bent movable cover 6 on the platform side is hooked onto the end of the movable sealing plate 2, pressing it against the door frame 5. Installation is completed simply by fixing the movable cover 6 to the door frame 5. When maintenance is required, the movable cover 6 is removed, and the corresponding movable sealing plate 2, no longer obstructed, rotates upward to open the head space of the platform door. This greatly increases the opening size and depth of the maintenance opening, greatly facilitating maintenance.

[0030] Furthermore, the movable sealing plate 2 is connected to the end of the rear sealing plate 1 via an elastic hinge 3. The elastic element is a coil spring inside the elastic hinge 3. Under the drive of the elastic hinge 3, the movable sealing plate 2 can rotate upward to the open state. In this application, the movable sealing plate 2 is connected to the rear sealing plate 1 via the elastic hinge 3. When closing, the movable sealing plate 2 is pulled down to overcome the spring force and close. When maintenance is required, only the movable cover plate 6 pressing on the movable sealing plate 2 needs to be removed, and the movable sealing plate 2 will automatically release and rise. This eliminates the need for disassembly, which is very convenient. Moreover, the design of the automatically rising movable sealing plate 2 ensures that its automatic opening range remains constant, without interfering with personnel operation, further facilitating maintenance.

[0031] Furthermore, the rear cover plate 1 includes a top cover portion 11, an extension portion 12, and the aforementioned positioning portion 13, all three being integrally formed. The extension portion 12 is inclined, and the top cover portion 11 and the positioning portion 13 are located at the highest and lowest points of the extension portion 12, respectively. The positioning portion 13 on the rear cover plate 1 of this application is used to fix it to the door frame 5. The inclined extension of the extension portion 12 can raise the height of the top cover portion 11, thus allowing for a larger headroom range when the movable cover plate 2 is connected to the top cover portion 11, facilitating maintenance. At the same time, the presence of the top cover portion 11 can shield the door frame 5 on the track side, effectively preventing dust from entering and better protecting the internal equipment.

[0032] Furthermore, the top cover 11 has a downwardly bent flange 14 at its end. The elastic hinge 3 is fixed to the inside of the flange 14, and the movable sealing plate 2 is located above the elastic hinge 3 with its end portion inserted into the inside of the flange 14. The elastic hinge 3 and other connecting components can be hidden below the top cover 11 and the movable sealing plate 2, reducing the exposure of components after closing and effectively improving sealing performance. The elastic hinge 3 is an externally purchased component and is a conventional existing technology, which will not be elaborated upon further here.

[0033] Furthermore, a sealing strip 4 is fixed to the end of the movable sealing plate 2 opposite to the elastic hinge 3, and the sealing strip 4 covers the outer edge of the movable sealing plate 2. The sealing strip 4 on the end of the movable sealing plate 2 of this application serves to seal the connection position when connected with the movable cover plate 6 on the platform side, so as to ensure the sealing performance of the platform screen door before and after maintenance.

[0034] Furthermore, the bottom of the sealing strip 4 has a downwardly protruding buffer portion 41, and the inner side of the buffer portion 41 has a buffer cavity 42 with a triangular outline. The buffer portion 41 is used to contact the door frame 5, which serves both as a buffer and a sealing function. Its built-in buffer cavity 42 deforms along with the sealing strip 4 after deformation. The overall buffer portion 41 can fill gaps and enhance sealing performance.

[0035] Furthermore, the top of the sealing strip 4 extends along the upper surface of the movable cover plate 2 to form an abutment portion 43. The abutment portion 43 at the top of the sealing strip 4 is used to contact the movable cover plate 6 on the platform side to form a seal.

[0036] Furthermore, the movable sealing plate 2 can rotate upwards to an opening angle of 60°. The large opening angle of the movable sealing plate 2 allows for a larger opening of the head space of the door frame 5, accommodating more in-depth maintenance operations.

[0037] Furthermore, the connection point between the movable sealing plate 2 and the rear sealing plate 1 is at a height higher than the height at which the upper edge of the movable cover plate 6 presses against the outer edge of the movable sealing plate 2. This design allows the movable sealing plate 2 to be opened at a higher overall height, providing workers with more operating space and facilitating maintenance.
