DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0028] Most of the current subway platform doors are made of stainless steel, which has the following defects:

[0029] (1) Generally, the surface of stainless steel is brushed in its natural color, which is monotonous and cannot be well matched with the decoration style of the platform door.

[0030] (2) Stainless steel door frames are generally welded and need to be polished after welding. They are prone to deformation due to internal stress factors, and it is difficult to ensure the external dimensions of the door body.

[0031] (3) Stainless steel doors are heavy, the system has high requirements for sliding door control, and the door is prone to resistance when opening under high wind pressure.

[0032] (4) The subway generally chooses a 1500V DC traction power supply system for its power supply system, and designs the rails as return rails. When the subway is in normal working condition, the rails may generate a voltage of up to 90V. At the same time, because the train and the rails are at the same potential, in order to ensure that passengers will not be harmed by the potential difference when getting on and off the train, the platform doors are required to be installed with insulation to the ground, and the platform door body and column surface are also required to be insulated. The conventional practice for stainless steel surfaces is to brush insulating varnish or apply insulating film on the surface, but both are difficult to construct and the insulation is prone to failure, which will cause safety hazards during the long-term operation of the subway.

[0033] Based on this, the present invention provides an aluminum alloy subway platform door device, which can solve the problems existing in the above-mentioned stainless steel subway platform doors.

[0034] An embodiment of the present invention relates to an aluminum alloy subway platform door device. The implementation details of the aluminum alloy subway platform door device of this embodiment are specifically described below. The following content is only the implementation details provided for easy understanding and is not necessary for implementing this solution.

[0035] The specific structure of the aluminum alloy subway platform door device of this embodiment can be as follows Figure 1 shown, and Figure 1 , a front view and a top view of an aluminum alloy subway platform door device are shown, and the aluminum alloy subway platform door device comprises: a threshold 1, a door lintel 2, a door body 3, and a column assembly 4 connected to the threshold 1, the door lintel 2 and the door body 3. The column assembly 4 can be used to support the threshold 1, the door lintel 2 and the door body 3, thereby enhancing the structural stability of the platform door and ensuring that the platform door can move smoothly along a predetermined track during opening and closing.

[0036] The threshold 1, the door lintel 2, the door frame of the door body 3 and the column assembly 4 of this embodiment are all made of aluminum alloy and are formed by stretching. Since the aluminum alloy is light in weight and easier to control, when the wind pressure in the subway tunnel is too high, the sliding door is not prone to failure of opening the door and encountering resistance. Moreover, the threshold 1, the door lintel 2, the door frame of the door body 3 and the column assembly 4 are all formed by stretching, so that the size of the aluminum alloy subway platform door device of this embodiment is easy to ensure.

[0037] At the same time, the aluminum alloy subway platform door device has various components made of aluminum alloy, namely the threshold 1, the lintel 2, the door frame of the door body 3 and the column assembly 4, and its inner and outer surfaces are both anodized and wood grain transfer processed, and its outer surface is insulated, and the insulation value is ≥0.5MΩ. Due to the use of anodizing (insulation) plus wood grain transfer (insulation) process, the surface insulation effect can be improved, and this double insulation process can ensure that the insulation value of the platform door surface is far greater than the requirement of 0.5MΩ, and the insulation is not easy to fail, ensuring the safety of the subway during long-term operation.

[0038] In a specific implementation, the threshold 1 can be made of an aluminum alloy profile as a whole. After the inner and outer surfaces of the aluminum alloy profile are anodized, the inner and outer surfaces of the threshold 1 are insulated, and the insulation value is ≥0.5MΩ, which is obtained by testing with a 500V megohmmeter. In other embodiments, the threshold 1 can also be composed of a carbon structural steel lining and a stainless steel outer plate.

[0039] The lintel 2 includes a lintel lining and a lintel outer covering plate. The lintel outer covering plate is arranged around the lintel lining and connected to the lintel lining by screws or rivets. The lintel lining is made of high-quality carbon structural steel, and the lintel outer covering plate is made of aluminum alloy and formed by stretching or bending. At the same time, the inner and outer surfaces of the lintel outer covering plate are both anodized and wood grain transferred, so that the inner and outer surfaces of the lintel outer covering plate are insulated, and the insulation value is ≥0.5MΩ.

[0040] The structure of the door body 3 is as follows Figure 2 As shown, Figure 2 The front view and top view of the door body 3 are shown. The door body 3 is composed of a door frame 31 and a tempered glass 32 bonded to the door frame 31. The four corners of the door frame 31 are hidden inside with connecting corners 311 and connecting plates 312. Figure 3 shown, and Figure 3 Schematic diagrams of various directions of a corner of the door frame 31 are shown in FIG.

[0041] The connecting angle bracket 311 is a rectangular groove, which is clamped in the horizontal frame at the corner of the door frame 31, and the size of the connecting angle bracket 311 matches the size of the cross section of the horizontal frame; and the connecting plate 312 is clamped in the vertical frame at the corner of the door frame 31 at a position that is consistent with the height of the connecting angle bracket 311, and the size of the connecting plate 312 matches the size of the cross section of the vertical frame. Therefore, the connecting angle bracket 311 and the connecting plate 312 further support the horizontal and vertical frames at the four corners of the door frame 31 inside the door frame 31, thereby ensuring the flatness and verticality of the four right angles of the door frame 31.

[0042] The clamping position of the connecting plate 312 in the vertical frame is highly consistent with the clamping position of the connecting angle bracket 311 in the horizontal frame. The connecting angle bracket 311 and the connecting plate 312 are fixedly connected by connecting screws 313, which can further fix the horizontal frame and vertical frame at the corner of the door frame 31, thereby ensuring the connection strength of the door frame. Furthermore, since the connecting angle bracket 311, the connecting plate 312 and the connecting screws 313 are all hidden inside the door frame 31, this hidden splicing design does not expose the connecting parts. After installation, the outer surface of the door frame 31 is smooth and flat, which can improve the consistency of the door body and the appearance quality.

[0043] It is understandable that if Figure 1 As shown, an aluminum alloy subway platform door device includes two door bodies 3, namely a left door body and a right door body, and both the left door body and the right door body include the above structure. Figure 2 As shown, the door frame 31 of each door body 3 includes an upper transverse frame, a lower transverse frame, a left vertical frame and a right vertical frame, and is assembled by the upper transverse frame, the lower transverse frame, the left vertical frame and the right vertical frame.

[0044] A skirting board 33 is provided between the threshold 1 and the door frame 31 of each door body 3. Figure 2 and Figure 4 As shown, the skirting board 33 and the lower transverse frame of the door frame 31 are provided with matching slots to clamp the skirting board 33 on the lower transverse frame of the door frame 31. The skirting board 33 is made of aluminum alloy and formed by stretching. Therefore, each door body 3 is assembled by the upper transverse frame, the lower transverse frame, the left vertical frame, the right vertical frame, the skirting board 33, the connecting angle code 311, the connecting plate 312 and the connecting screw 313.

[0045] In each door body 3, the upper horizontal frame, the lower horizontal frame, the left vertical frame, the right vertical frame, the skirting board 33 and the connecting angle code 311 are all made of aluminum alloy and formed by stretching; and the inner and outer surfaces of the upper horizontal frame, the lower horizontal frame, the left vertical frame, the right vertical frame and the skirting board 33 made of aluminum alloy are anodized and wood grain transfer treated, so that the inner and outer surfaces of the upper horizontal frame, the lower horizontal frame, the left vertical frame, the right vertical frame and the skirting board 33 are insulated, and the insulation value is ≥0.5MΩ.

[0046] The connecting angle code 311 is also made of aluminum alloy and formed by stretching, while the connecting plate 312 is made of high-strength carbon steel with a thickness between 4 mm and 8 mm.

[0047] The specific structure of the column assembly 4 is as follows Figure 5As shown, it includes a column 41, a column inner plate 42 and a column outer plate 43. The column inner plate 42 and the column outer plate 43 are arranged around the column 41, and the column inner plate 42 and the column outer plate 43 are connected to the column 41 by screws or rivets 44 in the figure. Among them, the material of the column 41 is high-quality carbon structural steel, and the material of the column inner plate 42 and the column outer plate 43 is aluminum alloy, and is formed by stretching. At the same time, the inner and outer surfaces of the column inner plate 42 and the column outer plate 43 made of aluminum alloy are both anodized and wood grain transfer treated, so that the inner and outer surfaces of the column inner plate 42 and the column outer plate 43 are insulated, and the insulation value is ≥0.5MΩ.

[0048] It should also be noted that the various components of the above-mentioned platform doors are made of aluminum alloy. The surface adhesion of aluminum alloy is better than that of stainless steel. At the same time, the wood grain transfer process can be matched with the decoration style of the subway station. Different wood grain patterns are used, which has a beautiful appearance and enhances the overall effect of the platform door.

[0049] In this embodiment, the materials of the threshold, lintel, door frame of the door body and the column assembly of the subway platform door device are all aluminum alloy, and connecting angle codes and connecting plates are hidden inside the four corners of the door frame. The connecting angle code is a rectangular groove, which is clamped in the horizontal frame at the corner of the door frame, and the size of the connecting angle code matches the size of the cross-section of the horizontal frame; the connecting plate is clamped in the vertical frame at the corner at a position consistent with the height of the connecting angle code, and the size of the connecting plate matches the size of the cross-section of the vertical frame; the connecting angle code and the connecting plate are fixedly connected by connecting screws to fix the horizontal frame and the vertical frame at the corner of the door frame.

[0050] Among them, the setting of the connection angle bracket and the connection plate can further support the four corners of the door frame inside the door frame, which not only improves the connection strength of the door frame, but also ensures the flatness and verticality of the door frame corners. The design of aluminum alloy material can reduce the weight of the platform door body and is easy to control, thereby ensuring the strength of the door body and avoiding the phenomenon of the platform door encountering resistance when the wind pressure in the subway tunnel is too high. In addition, the connection angle bracket, connection plate and connection screws are all hidden inside the door frame. This hidden splicing design does not expose the connection parts. After installation, the outer surface of the door frame is smooth and flat, which can improve the consistency of door body forming and appearance quality.

[0051] Those skilled in the art can understand that the above embodiments are specific embodiments of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the embodiments of the present invention. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the embodiments of the present invention, so the protection scope of the embodiments of the present invention shall be based on the scope defined in the claims.
