Description

Technical Field

[0001] The utility model relates to the technical field of rail transit platforms, in particular to a platform door top box and a platform door. Background Art

[0002] In rail transit, platform doors are a crucial line of defense for protecting passengers. Installed at the edge of the platform, between trains and passengers, they shield and guide passengers as they board and alight. Platform doors consist of a door body and a top box, which must be connected to the platform's civil air duct beams to limit the top of the platform door.

[0003] In the prior art, the top box of the platform door is usually connected to the air duct beam of the platform directly by connecting parts such as bolts, thereby directly connecting and sealing the top box and the air duct beam.

[0004] However, in the above-mentioned existing technology, affected by the actual construction quality, the surface where the air duct beam is connected to the platform door top box may be uneven, affecting the sealing effect. In addition, in some cases, the platform adopts prefabricated construction. In this case, it is difficult to subsequently drill holes at the bottom of the air duct beam, and the connection between the platform door top box and the air duct beam cannot be achieved through connecting parts. Utility Model Content

[0005] In view of this, the utility model provides a platform door with a sealing structure to solve the problem that the installation of the platform door is affected by the platform construction method and construction quality, resulting in poor sealing effect or inability to achieve fixed connection between the top box and the air duct beam.

[0006] In the first aspect, the utility model provides a platform door top box, comprising: a box body; a mounting frame, fixedly mounted on the box body and having a mounting plane, wherein the mounting plane is suitable for abutting and fixedly connected to the side wall of the air duct beam; a sealing frame, comprising a mounting plate and a sealing strip, wherein the lower end of the mounting plate is fixedly connected to the box body, and the upper end of the mounting plate is provided with a sealing strip, and the sealing strip abuts against the lower end surface of the air duct beam.

[0007] Beneficial effect: By setting up the mounting frame, the box body can be fixedly connected to the side wall of the duct beam, thereby realizing the fixation of the top box. When it extends to the lower side of the duct beam through the sealing frame, it abuts against the bottom of the duct beam through the sealing strip on the sealing frame. Since the sealing strip is elastic, it can fit well with the lower surface of the duct beam through elastic deformation, avoiding the situation where the uneven lower side wall of the duct beam affects the sealing effect between the duct beam and the top box. At the same time, it also avoids the situation where when the platform is constructed with prefabricated components, the lower side of the duct beam cannot be drilled in the subsequent construction, making it difficult for the top box to be fixedly connected to the duct beam.

[0008] In an optional embodiment, a folded edge is provided on the top of the mounting plate, and the folded edge extends upwardly and obliquely toward a side away from the box body, and the sealing strip is provided at the top end of the folded edge.

[0009] Beneficial effect: Since there is a folded edge on the top of the mounting plate, during the installation of the device, the setting of the folded edge can, on the one hand, adjust the position of the sealing strip so that the sealing strip extends to the lower side of the duct beam; on the other hand, the staff can slightly adjust the height of the sealing strip by adjusting the bending angle of the folded edge, thereby improving the fit between the sealing strip and the lower side wall of the duct beam and improving the sealing effect.

[0010] In an optional embodiment, the mounting plate abuts against the side wall of the box body and is detachably connected to the box body, and the sealing strip is detachably connected to the folded edge.

[0011] Beneficial effects: The detachable connection between the mounting plate and the box body facilitates the workers to fine-tune the inclination angle of the folded edge on site, and facilitates the workers to select mounting plates of different sizes according to actual conditions. The detachable connection between the sealing strip and the folded edge facilitates the workers to select sealing strips of different models and sizes according to actual construction conditions on site. At the same time, since the folded edge on the mounting plate is inclined away from the box body, the mounting plate, the sealing strip and the box body are separated, and the mounting plate and the folded edge can be removed from the box body as a whole during transportation, which facilitates the transportation and storage of components.

[0012] In an optional embodiment, a clamping portion is provided on the side of the folded edge away from the mounting plate, the thickness of the clamping portion is greater than the folded edge, and a plug-in groove is provided on the side of the sealing strip facing the mounting plate, and the plug-in groove is adapted to the clamping portion.

[0013] Beneficial effect: By providing a clamping portion and providing a plug-in groove on the sealing strip, the structural stability of the joint between the sealing strip and the folded edge is improved, and the sealing strip is reduced from falling off or loosening from this side, resulting in sealing failure.

[0014] In an optional embodiment, the plug-in slot is provided with multiple groups of limiting members arranged at intervals along the depth direction of the plug-in slot, and the limiting members include two elastic limiting petals arranged opposite to each other and abutting against each other. The multiple groups of limiting members divide the plug-in slot into multiple limiting cavities matching the clamping part.

[0015] Beneficial effect: By arranging multiple groups of limiting parts consisting of relatively arranged limiting petals in the plug-in slot, multiple limiting cavities are limited in the plug-in slot, and each limiting cavity can limit the clamping part, so that the sealing strip has multiple stably limited positions on the folded edge. The staff can adjust the position of the sealing strip as needed to better adapt to the height of the lower side wall of the duct beam, thereby improving the sealing effect.

[0016] In an optional embodiment, the clamping portion is formed by folding back an edge of the folded edge away from the mounting plate.

[0017] Beneficial effect: The method of folding the side edge back to form the clamping portion is convenient to process, and this side, the mounting plate and the clamping portion can be quickly processed and formed on the same plate, with low processing cost, which helps to increase component production.

[0018] In an optional embodiment, the box body includes a base frame, a front cover plate and a rear cover plate, the front cover plate and the rear cover plate are respectively fixedly connected to the base frame, the front cover plate is located on the side of the rear cover plate away from the track, the sealing frame is arranged at the upper end of the rear cover plate, and the mounting frame is arranged at the upper end of the base frame.

[0019] Beneficial effects: The base frame provides a structural basis for the connection between the front cover plate and the rear cover plate. The base frame is connected to the side wall of the air duct beam through the mounting frame, so that the front cover plate and the rear cover plate are respectively positioned relative to the air duct beam. The sealing frame is connected to the rear cover plate, thereby achieving sealing between the air duct beam and the box body.

[0020] In an optional embodiment, the mounting frame includes a first connecting plate and a second connecting plate vertically connected to each other, the first connecting plate is connected to the air duct beam, the second connecting plate is connected to the upper end of the base frame, and a reinforcing rib is fixed between the first connecting plate and the second connecting plate.

[0021] Beneficial effect: Through the setting of the first connecting plate and the second connecting plate, two mutually perpendicular mounting planes are formed on the mounting frame, thereby realizing the connection between the top of the base frame and the side wall of the air duct beam, and the setting of the reinforcing ribs improves the strength of the mounting frame, making the connection between the top box and the air duct beam more reliable.

[0022] In an optional embodiment, a cavity is provided inside the sealing strip, and the cavity extends along the length direction of the sealing strip.

[0023] Beneficial effect: Since a cavity extending along the length of the sealing strip is provided in the sealing strip, the deformation ability of the sealing strip is greatly improved. When the lower side wall of the air duct beam is quite uneven, the sealing strip can still maintain a good fit with the lower side wall of the air duct beam by deforming itself, thereby ensuring the sealing effect.

[0024] In a second aspect, the utility model further provides a platform door, comprising: a door body; the above-mentioned platform door top box, wherein the box body is arranged on the top of the door body and slides with the door body.

[0025] Beneficial effect: By adopting the above-mentioned top box structure, the platform door enables the top box to be smoothly installed on the prefabricated air duct beam whose bottom cannot be subsequently opened, and can be sealed with the uneven air duct beam on the bottom side, thereby improving the practicality of the structure.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0032] The following combination Figures 1 to 2 , describing the embodiments of the present utility model.

[0033] According to an embodiment of the present invention, a platform door top box is provided. Figure 1 and Figure 2, including: a box body 100; a mounting frame 200, fixedly mounted on the box body 100 and having a mounting plane, the mounting plane being suitable for abutting and fixedly connected to the side wall of the air duct beam 400; a sealing frame 300, including a mounting plate 301 and a sealing strip 302, the lower end of the mounting plate 301 being fixedly connected to the box body 100, the upper end of the mounting plate 301 being provided with a sealing strip 302, the sealing strip 302 abutting against the lower end surface of the air duct beam 400.

[0034] In this embodiment, by providing a mounting frame 200, the box body 100 can be fixedly connected to the side wall of the air duct beam 400, thereby realizing the fixation of the top box. When it extends to the lower side of the air duct beam 400 through the sealing frame 300, the sealing strip 302 on the sealing frame 300 abuts against the bottom of the air duct beam 400. Since the sealing strip 302 is elastic, it can elastically deform to fit well with the lower surface of the air duct beam 400, thereby avoiding the situation where the uneven lower side wall of the air duct beam 400 affects the sealing effect between the air duct beam 400 and the top box. At the same time, it also avoids the situation where, when the platform is constructed with prefabricated components, the lower side of the air duct beam 400 cannot be drilled in subsequent construction, making it difficult for the top box to be fixedly connected to the air duct beam 400.

[0035] Specifically, in the above embodiment, there is no restriction on the specific forms of the mounting frame 200 and the sealing frame 300. The mounting frame 200 can connect the side wall of the air duct beam 400 with the box body 100, and the sealing frame 300 can be connected to the box body 100 and installed with the sealing strip 302.

[0036] In addition, it should be noted that the sealing strip 302 can be integrally formed with the mounting plate 301. For example, the mounting plate 301 is made of a rubber plate, and the sealing strip 302 is made of a rubber material and is provided on the mounting plate 301. The sealing strip 302 can also be separately provided from the mounting plate 301. For example, the sealing strip 302 is connected to the mounting plate 301 through a connector or by bonding.

[0037] In one embodiment, a folded edge 3011 is provided on the top of the mounting plate 301 . The folded edge 3011 extends obliquely upward toward a side away from the box body 100 . The sealing strip 302 is provided on the top of the folded edge 3011 .

[0038] In this embodiment, since a folded edge 3011 is provided on the top of the mounting plate 301, during the installation of the device, the setting of the folded edge 3011 can, on the one hand, adjust the position of the sealing strip 302 so that the sealing strip 302 extends toward the lower side of the air duct beam 400; on the other hand, the staff can slightly adjust the height of the sealing strip 302 by adjusting the bending angle of the folded edge 3011, thereby improving the fit between the sealing strip 302 and the lower side wall of the air duct beam 400 and enhancing the sealing effect.

[0039] In one embodiment, the mounting plate 301 abuts against the side wall of the box body 100 and is detachably connected to the box body 100 , and the sealing strip 302 is detachably connected to the folded edge 3011 .

[0040] Specifically, this embodiment does not limit the specific form of the detachable connection between the sealing strip and the folding edge 3011. In some embodiments not shown, for example, the sealing strip can be bonded to the folding edge 3011, or it can be connected to the mounting plate 301 through a connector.

[0041] In this embodiment, the mounting plate 301 is detachably connected to the box body 100, which makes it convenient for the staff to fine-tune the inclination angle of the folded edge 3011 on site, and makes it convenient for the staff to select mounting plates 301 of different sizes according to actual conditions. The detachable connection between the sealing strip 302 and the folded edge 3011 makes it convenient for the staff to select sealing strips 302 of different models and sizes according to actual construction conditions on site. At the same time, since the folded edge 3011 on the mounting plate 301 is inclined away from the box body 100, the mounting plate 301, the sealing strip 302 and the box body 100 are separated, and the mounting plate 301 and the folded edge 3011 are removed from the box body 100 as a whole during transportation, which facilitates the transportation and storage of components.

[0042] In one embodiment, a clamping portion 3012 is provided on the side of the folded edge 3011 away from the mounting plate 301 , and the clamping portion 3012 is thicker than the folded edge 3011 . A plug-in groove 3021 is provided on the side of the sealing strip 302 facing the mounting plate 301 , and the plug-in groove 3021 is adapted to the clamping portion 3012 .

[0043] In this embodiment, by providing a snap-fit ​​portion 3012 and providing an inserting groove 3021 on the sealing strip 302, the structural stability of the installation joint between the sealing strip 302 and the folding edge 3011 is improved, and the sealing strip 302 is reduced from falling off or loosening from this side, resulting in sealing failure.

[0044] In one embodiment, the plug-in slot 3021 is provided with multiple groups of limiting members arranged at intervals along the depth direction of the plug-in slot 3021. The limiting members include two elastic limiting petals 3022 that are arranged opposite to each other and abut against each other. The multiple groups of limiting members separate the plug-in slot 3021 into multiple limiting cavities 3023 that match the clamping portion 3012.

[0045] In this embodiment, by arranging multiple groups of limiting members consisting of relatively arranged limiting petals in the plug-in slot 3021, multiple limiting cavities 3023 are limited in the plug-in slot 3021. Each limiting cavity 3023 can limit the clamping portion 3012, so that the sealing strip 302 has multiple stably limited positions on the folded edge 3011. The staff can adjust the position of the sealing strip 302 as needed to better adapt to the height of the lower side wall of the air duct beam 400, thereby improving the sealing effect.

[0046] In one embodiment, the clamping portion 3012 is formed by folding back an edge of the folded edge 3011 away from the mounting plate 301 .

[0047] In this embodiment, the method of folding the side of the folded edge 3011 to form the clamping portion 3012 is convenient to process, and this side, the mounting plate 301 and the clamping portion 3012 can be quickly processed and formed on the same plate, with low processing cost, which helps to increase component production.

[0048] In one embodiment, the box body 100 includes a base frame 101, a front cover plate 102 and a rear cover plate 103. The front cover plate 102 and the rear cover plate 103 are respectively fixedly connected to the base frame 101. The front cover plate 102 is located on the side of the rear cover plate 103 away from the track. The sealing frame 300 is arranged at the upper end of the rear cover plate 103, and the mounting frame 200 is arranged at the upper end of the base frame 101.

[0049] In this embodiment, the base frame 101 provides a structural basis for the connection between the front cover plate 102 and the rear cover plate 103. The base frame 101 is connected to the side wall of the air duct beam 400 through the mounting frame 200, so that the front cover plate 102 and the rear cover plate 103 are respectively positioned relative to the air duct beam 400. The sealing frame 300 is connected to the rear cover plate 103, thereby achieving sealing between the air duct beam 400 and the box body 100.

[0050] In one embodiment, the mounting frame 200 includes a first connecting plate 201 and a second connecting plate 202 vertically connected to each other, the first connecting plate 201 is connected to the air duct beam 400, the second connecting plate 202 is connected to the upper end of the base frame 101, and a reinforcing rib 203 is fixed between the first connecting plate 201 and the second connecting plate 202.

[0051] In this embodiment, by setting the first connecting plate 201 and the second connecting plate 202, two mutually perpendicular mounting planes are formed on the mounting frame 200, thereby realizing the connection between the top of the base frame 101 and the side wall of the air duct beam 400, and the setting of the reinforcing ribs 203 improves the strength of the mounting frame 200, making the connection between the top box and the air duct beam 400 more reliable.

[0052] In one embodiment, a cavity 303 is defined inside the sealing strip 302 , and the cavity 303 extends along the length direction of the sealing strip 302 .

[0053] In this embodiment, since a cavity 303 extending along the length direction of the sealing strip 302 is provided in the sealing strip 302, the deformation ability of the sealing strip 302 is greatly improved. When the lower side wall of the air duct beam 400 is quite uneven, the sealing strip 302 can still maintain a good fit with the lower side wall of the air duct beam 400 by deforming itself, thereby ensuring the sealing effect.

[0054] According to an embodiment of the present invention, on the other hand, a platform door is provided, comprising: a door body; the above-mentioned platform door top box, wherein the box body 100 is arranged on the top of the door body and slides with the door body.

[0055] In this embodiment, the platform door adopts the above-mentioned top box structure, so that the top box can be smoothly installed on the prefabricated air duct beam 400 where no holes can be opened at the bottom, and can be sealed with the uneven bottom side of the air duct beam 400, thereby improving the practicality of the structure.

[0056] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
