Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a platform door top box movable panel assembly. Background Art

[0002] With the development of subway construction, the requirements for the structure and installation of platform screen doors and safety doors are getting higher and higher. The existing platform door top box movable panel usually adopts a sliding support with a limit plate. The opening and closing of the movable panel is realized by the extension and contraction of the sliding support, and the opening position of the movable panel can be fixed and limited by the limit plate, that is, the user manually moves the limit plate to snap into the outer rod of the sliding support connecting the movable panel, so that the sliding support is limited and the movable panel is fixed, which is more troublesome to operate. In addition, the movable panel is a thin and long member with low rigidity. Generally, sliding supports are used on both sides for connection. When opening the movable panel, multiple people are required to operate at the same time. If the operation is not careful, it is easy to have only one side of the sliding support limited, while the other side is still in a free state, which affects the structural safety and makes the sliding support under the structural force in an unfavorable position, which is easy to be damaged due to the actual load exceeding the design load; and when the movable panel is integrated with a display screen and other devices, it requires operators to spend a lot of effort to open and close the movable panel using traditional sliding supports.

[0016] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated below in conjunction with schematic diagrams, but is not limited thereto.

[0017] Reference Figures 1 to 3 , Figures 1 to 3 A specific embodiment of the platform door top box movable panel assembly of the utility model is shown. In the embodiment shown in the drawings, the platform door top box movable panel assembly includes a movable panel 2 and a gas pressure support 1, the movable panel 2 is covered on the platform door top box bracket 4, and the top end is hinged to the platform door top box bracket 4; one end of the gas pressure support 1 is hinged to the platform column 5 and can rotate relative to the platform column 5, and the other end is connected to the movable panel 2, and the piston rod 12 of the gas pressure support 1 extends when the movable panel 2 is opened. Based on the above design, the gas pressure support 1 extends when the movable panel 2 is opened, and compresses when the movable panel 2 is closed and retracted; and when the movable panel 2 needs to be opened, the user only needs to exert a little force to pull the movable panel 2 apart a distance, and the piston rod 12 of the gas pressure support 1 is pushed out. At this time, the thrust direction of the gas inside the gas pressure support 1 is the direction of pushing the movable panel 2 to open. Under the action of the gas pressure support 1, the movable panel 2 will open automatically, and finally stop and remain at the extreme position of the gas pressure support 1, revealing the maintenance space inside the platform door top box. It does not require multiple people to operate, is safe and labor-saving, and the movable panel 2 is always supported by the gas pressure support 1, eliminating the risk of accidental closing of the movable panel 2.

[0018] In certain embodiments, such as Figure 1 and Figure 3 As shown, the gas pressure support 1 includes a piston cylinder 11 filled with gas and a piston rod 12 connected to the piston cylinder 11. The piston cylinder 11 and the piston rod 12 are also connected to a cylinder end connector 13 and a rod end connector 14, respectively. The other ends of the cylinder end connector 13 and the rod end connector 14 are hinged to the movable panel 2 and the platform column 5, respectively. In this embodiment, nitrogen with a certain pressure can be filled into the piston cylinder 11, and a piston ring can be installed at the connection between the piston cylinder 11 and the piston rod 12, so that a closed space is formed inside the piston cylinder 11. The piston rod 12 can be extended by the gas in the piston cylinder 11, and will only retract when constrained by an external force. It can be understood that the air pressure in the cylinder does not change much within the stroke range of the piston rod 12, so the force within its stroke range does not change. The specifications of the gas pressure support 1 and the internal gas pressure can be set according to the structural size and opening space of the movable panel 2.

[0019] In certain embodiments, such as Figure 1 and Figure 2As shown, a fixing part 51 is installed on the platform column 5, and the fixing part 51 includes a first fixing plate 511 and a second fixing plate 512 bent outward from one side of the first fixing plate 511, the first fixing plate 511 is fixed to the surface of the platform column 5, and the second fixing plate 512 is perpendicular to the surface of the platform column 5, and the rod end connector 14 is hinged to the second fixing plate 512 through a rotating shaft.

[0020] Furthermore, in this embodiment, a fixed wing 21 is installed on the movable panel 2, and the fixed wing 21 is perpendicular to the surface of the movable panel 2, and the cylinder end connector 13 is hinged on the fixed wing 21. Based on the above design, the cylinder end connector 13 and the rod end connector 14 on the gas pressure support 1 are respectively hinged on the fixed wing 21 and the second fixed plate 512, and the fixed wing 21 and the second fixed plate 512 are respectively perpendicular to the surface of the movable panel 2 and the platform column 5. In the process of closing the movable panel 2, the piston rod 12 of the gas pressure support 1 is gradually retracted, and the cylinder end connector 13 and the rod end connector 14 can rotate relative to the platform column 5 and the movable panel 2 respectively. When the movable panel 2 is completely closed, the gas pressure support 1 is roughly parallel to the platform column 5 and the surface of the movable panel 2. At this time, the thrust direction of the gas inside the gas pressure support 1 is the vertical direction, and the top of the movable panel 2 is hinged on the platform door top box bracket 4, and an outward thrust is required to open it. At this time, the gas pressure support 1 can hinder the opening of the movable panel 2.

[0021] Understandably, the movable panel assembly of the platform door top box of the utility model has its own power assist, and no ladder is needed when in use. It can be opened on the platform, and the heavier movable panel 2 is driven by the gas pressure support 1 to open until it is opened to the maximum angle, exposing the complete maintenance space inside the platform door top box. That is, when the movable panel 2 needs to be opened, the user applies a little force to pull the movable panel 2 away by a distance, and the thrust direction of the gas inside the gas pressure support 1 is the direction of pushing the movable panel 2 to open. The piston rod 12 of the gas pressure support 1 extends, and the movable panel 2 continues to open automatically under the action of the thrust, and finally stops and remains at the extreme position of the gas pressure support 1 (such as Figure 2 As shown), the risk of accidental closing of the movable panel 2 is avoided; when the movable panel 2 needs to be closed, the movable panel 2 is pulled toward the platform column 5, and the piston rod 12 of the gas pressure support 1 is compressed. After the movable panel 2 is closed, the gas pressure support 1 can prevent the movable panel 2 from opening.

[0022] In summary, the air pressure support of the movable panel assembly of the platform door top box of the utility model can assist in the opening of the movable panel, so that the opening angle of the movable panel is larger, and after opening the movable panel, it can also avoid the maintenance operation risks caused by accidental closure of the movable panel due to unexpected factors.

Any technical deductions, replacements, improvements, etc. that are identical or similar to the utility model scheme or made based on it should be regarded as within the scope of protection of this patent.
