DETAILED DESCRIPTION
[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the embodiments of the utility model will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the utility model, many technical details are proposed in order to make the readers better understand the utility model. However, even if there is no such technical details and various changes and modifications based on the following embodiments, the technical scheme claimed by the utility model can be realized. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation mode of the utility model, and the embodiments can be combined and quoted with each other under the premise of no contradiction.
[0028] Most of the current subway platform doors adopt stainless steel door bodies, which have the following defects:
[0029] (1) The surface of the general stainless steel is stainless steel color wire drawing treatment, which is monotonous in color and cannot be well matched with the decoration style of the platform door.
[0030] (2) The stainless steel door frame generally adopts a welding process, and needs to be polished after welding. Due to the internal stress factor, it is easy to deform and difficult to ensure the shape size of the door body.
[0031] (3) The stainless steel door body is heavy, the system has high requirements for the control of the sliding door, and the phenomenon of door opening resistance is easy to occur under high wind pressure.
[0032] (4) The subway generally selects a 1500V direct current traction power supply system in the power supply system, and designs the steel rail as a return rail. When the subway is in a normal working state, the steel rail may generate a voltage of up to 90V. At the same time, because the train and the steel rail belong to the same potential relationship, in order to ensure that passengers will not be harmed due to the potential difference during the process of getting on and off the train, it is required that the platform door is installed with ground insulation, and the surface of the platform door body and the stand column is also required to be insulated. The conventional method for the stainless steel surface is to brush insulating varnish or paste insulating film on the surface, but both are not easy to construct and the insulation is easy to fail, which will cause safety hazards during the long-term operation of the subway.
[0033] Based on this, the utility model provides an aluminum alloy subway platform door device, which can solve the problems existing in the above-mentioned stainless steel subway platform door.
[0034] One embodiment of the utility model relates to an aluminum alloy subway platform door device, and the implementation details of the aluminum alloy subway platform door device of the embodiment will be specifically described below. The following content only provides implementation details for the convenience of understanding, and is not necessary for implementing the scheme.
[0035] The specific structure of the aluminum alloy subway platform door device of the embodiment can be as shown in Figure 1 , and Figure 1The image shows a front view and a top view of an aluminum alloy subway platform screen door assembly. This assembly includes a threshold 1, a lintel 2, a door body 3, and a column assembly 4 connected to the threshold 1, lintel 2, and door body 3. The column assembly 4 supports the threshold 1, lintel 2, and door body 3, enhancing the structural stability of the platform screen door and ensuring smooth movement along a predetermined track during opening and closing.
[0036] In this embodiment, the threshold 1, lintel 2, door frame 3, and column assembly 4 are all made of aluminum alloy and are formed by stretching. Because aluminum alloy is lightweight and easier to control, the sliding door is less prone to obstruction when the wind pressure in the subway tunnel is too high. Furthermore, the use of stretching forming for the threshold 1, lintel 2, door frame 3, and column assembly 4 ensures that the dimensions of the aluminum alloy subway platform door device in this embodiment are easily guaranteed.
[0037] Meanwhile, all components of this aluminum alloy subway platform door device, namely the threshold 1, lintel 2, door frame 3, and column assembly 4, are made of aluminum alloy. Both their inner and outer surfaces undergo anodizing with wood grain transfer printing, and their outer surface is insulated with an insulation value ≥0.5MΩ. The use of anodizing (insulation) combined with wood grain transfer printing (insulation) enhances surface insulation, and this double insulation process ensures that the surface insulation value of the platform door far exceeds the 0.5MΩ requirement, preventing insulation failure and guaranteeing safety during long-term subway operation.
[0038] In a specific implementation, the threshold 1 can be made of aluminum alloy profile. 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 liner and a stainless steel outer cladding plate.
[0039] The lintel 2 includes an inner lintel and an outer lintel panel. The outer lintel panel is positioned around the inner lintel and connected to it via screws or rivets. The inner lintel is made of high-quality carbon structural steel, while the outer lintel panel is made of aluminum alloy and formed through stretching or bending. Both the inner and outer surfaces of the outer lintel panel undergo anodizing with a wood grain transfer printing process, ensuring insulation between the inner and outer surfaces with an insulation value ≥0.5MΩ.

Therefore, the connecting corner code 311 and the connecting plate 312 further support the horizontal and vertical frames of the four corners of the door frame 31 inside the door frame 31, thereby ensuring the flatness and perpendicularity of the right angles of the four corners of the door frame 31.
[0042] The clamping position of the connecting plate 312 in the vertical frame is consistent with the clamping position of the connecting corner code 311 in the horizontal frame, and the connecting corner code 311 and the connecting plate 312 are fixedly connected through the connecting screw 313, which can further fix the horizontal frame and the vertical frame of the corner of the door frame 31 and ensure the connection strength of the door frame. In addition, the connecting corner code 311, the connecting plate 312 and the connecting screw 313 are all hidden inside the door frame 31, and the hidden splicing design does not expose the connecting components, and the outer surface of the door frame 31 is smooth and flat after installation, which can improve the consistency of the door body and the appearance quality.

[0045] In each door body 3, the upper horizontal frame, lower horizontal frame, left vertical frame, right vertical frame, kick plate 33 and connecting corner bracket 311 are all made of aluminum alloy and are formed by stretching. The inner and outer surfaces of the upper horizontal frame, lower horizontal frame, left vertical frame, right vertical frame and kick plate 33, which are made of aluminum alloy, are all treated with anodizing and wood grain transfer, so that the inner and outer surfaces of the upper horizontal frame, lower horizontal frame, left vertical frame, right vertical frame and kick plate 33 are insulated and the insulation value is ≥0.5MΩ.
[0046] Among them, the connecting corner bracket 311 is also made of aluminum alloy and is formed by stretching, while the connecting plate 312 is made of high-strength carbon steel with a thickness between 4mm and 8mm.

Furthermore, both the inner and outer surfaces of the aluminum alloy inner column cladding plate 42 and the outer column cladding plate 43 are anodized with a wood grain transfer finish, ensuring insulation of both surfaces with an insulation value ≥0.5MΩ.
[0048] It should also be noted that all components of the aforementioned platform screen doors are made of aluminum alloy. Aluminum alloy has better adhesion than stainless steel. In addition, the wood grain transfer process can match the decoration style of the subway station, using different wood grain patterns, which makes the appearance beautiful and enhances the overall effect of the platform screen doors.
