Description

Technical Field

[0001] The utility model relates to the field of platform door installation structures, in particular to a bottom supporting mechanism for rail transit platform doors. Background Art

[0002] The bottom support mechanism for rail transit platform doors is a specially designed mechanism used to support and stabilize the platform doors to ensure their safety and stability during use. The bottom support mechanism for rail transit platform doors is a complex and sophisticated mechanical system. Its design and use need to consider many factors, including the weight, size, frequency of use of the platform doors, and the safety of passengers. With the advancement of technology and continuous innovation, the design of these support mechanisms is also constantly being optimized and improved.

[0003] The existing bottom support mechanism of rail transit platform doors has some obvious defects during the installation process. The traditional method is mainly to install it through bolt piles fixed on the ground, which requires the installation holes at the bottom of the shielding door to be accurately aligned with the bolt piles. However, since the platform shielding door weighs three or four hundred kilograms, this step becomes extremely difficult. The huge weight of the shielding door not only makes accurate alignment a challenge, but any slight deviation may lead to installation failure, and then reinstallation is required, which undoubtedly increases the difficulty and time cost of the operation. At the same time, the staff needs to move and position such a heavy shielding door during the installation process, which not only poses a severe challenge to their physical fitness, but also poses a potential safety hazard. Careless operation may cause injury to staff or damage to equipment. In order to solve these problems, a new type of bottom support mechanism for rail transit platform doors is urgently needed to simplify the installation process, reduce the difficulty of operation, and improve the safety and efficiency of the installation process. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a bottom support mechanism for rail transit platform doors, so as to solve the technical problem that the traditional bottom support mechanism for rail transit platform doors is difficult to install.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bottom support mechanism for a rail transit platform door, comprising a platform and a platform door, wherein a mounting groove is provided in the middle of the top of the platform, a side groove is provided on one side of the mounting groove, and the side groove penetrates to the outside of the platform, the platform door comprises a main body, a base is provided at the bottom of the main body, and the base is plugged into the mounting groove;

[0006] A slot is provided on one side of the base, and the side slot is opposite to the slot;

[0007] A fixing mechanism is arranged at the back of the side groove, and the fixing mechanism comprises a fixing plate. An inserting plate is arranged on the outer surface of the fixing plate. The inserting plate is plugged into the side groove and the slot, and the inserting plate is used to fix the platform door.

[0008] By adopting the above technical solution, the design of the fixing mechanism adopts a plug-in method to connect the platform and platform door. Compared with traditional bolt connection or welding, this connection method is simpler and faster. When installing or disassembling the platform door, you only need to insert or pull out the base into or out of the installation slot, and then fix or unlock it through the plug plate to complete the installation or disassembly process. This design greatly simplifies the installation and disassembly steps, improves work efficiency, and also facilitates the daily maintenance and replacement of the platform door.

[0009] Furthermore, the main body and the base are made of aluminum alloy, and the fixing mechanism is made of stainless steel.

[0010] By adopting the above technical solution, the stainless steel material has good corrosion resistance. The use of stainless steel in the fixing mechanism can effectively resist corrosion factors in harsh environments, such as rain, dirt, etc., thereby extending the service life of the platform door. At the same time, aluminum alloy also has a certain corrosion resistance, which enables the main body and base to remain stable under changing climatic conditions and reduce maintenance costs.

[0011] Furthermore, two side grooves are provided, and the two side grooves are mirror-imaged along the length center line of the platform.

[0012] By adopting the above technical solution, the symmetry of the platform door structure is achieved by mirroring two side grooves along the center line of the platform length. This symmetry not only improves the aesthetics of the platform door, but also ensures its uniform distribution when subjected to force. Structural symmetry helps reduce structural distortion or damage caused by unbalanced forces, thereby extending the service life of the platform door.

[0013] Furthermore, the fixing plate and the top rear end of the platform are provided with first fixing holes, and the two first fixing holes are positioned relative to each other.

[0014] By adopting the above technical solution, the mirrored side grooves make the installation process of the platform door simpler and more intuitive. The installers only need to install it according to the principle of symmetry without complicated measurements and adjustments. This design reduces installation time and labor costs and improves installation efficiency. At the same time, it also reduces the risk of installation errors and ensures the installation quality and safety of the platform door.

[0015] Furthermore, second fixing holes are provided on the back of the fixing plate and the back of the platform, and the two second fixing holes are opposite to each other.

[0016] By adopting the above technical solution, by setting relatively positioned first fixing holes at the top rear ends of the fixing plate and the platform, precise alignment between the fixing plate and the platform can be ensured during the installation process. This design simplifies the installation steps and improves the installation accuracy, thereby ensuring the stability and safety of the platform door. The precise positioning also facilitates the subsequent installation of the fixing bolts, making the entire installation process more efficient and accurate.

[0017] Furthermore, the first fixing hole and the second fixing hole are both threadedly connected with fixing bolts, and the fixing plate is detachably connected to the platform via the fixing bolts.

[0018] By adopting the above technical solution, a stable connection between the fixed plate and the platform can be ensured by means of threaded fixing bolts. The threaded connection has good tensile strength and shear strength, and can effectively resist external forces to prevent the platform door from loosening or shifting. This connection method ensures the stability and safety of the platform door and provides passengers with a reliable safety barrier.

[0019] Furthermore, the fixing plate is snap-connected with the edge of the platform.

[0020] By adopting the above technical solution, the stability of the entire supporting mechanism can be enhanced by connecting the fixed plate and the edge of the platform by snap-fitting. This connection method can effectively prevent the fixed plate from being displaced or loosened due to external force, ensuring that the platform door always remains stable, thereby improving the safety and comfort of passengers.

[0021] Furthermore, a movable groove is provided inside the main body, and a movable door is slidably connected inside the movable groove.

[0022] By adopting the above technical solution, through the sliding connection design between the movable groove and the movable door, the movable door can slide open and close smoothly in the movable groove. This design makes the door opening and closing action faster and smoother, thereby reducing the waiting time for passengers and improving the traffic efficiency. Especially during peak hours, it can quickly evacuate people and reduce congestion.

[0023] Furthermore, a warning light is arranged on the top of the main body, and the warning light is used to prompt the opening and closing of the movable door.

[0024] By adopting the above technical solution, the advantage of arranging a warning light on the top of the main body is that it can intuitively and timely remind passengers and staff of the current status of the movable door.

[0025] Furthermore, the platform door is electrically connected to an external power source.

[0026] By adopting the above technical solution, the electrical connection between the platform door and the external power supply ensures continuous and stable power supply to the platform door and its related electrical equipment.

[0027] In summary, the utility model mainly has the following beneficial effects:

[0028] 1. The utility model provides a fixing mechanism, a platform door, a base, and a slot, and provides a plug-in connection method between the installation slot and the base, so that the platform door can be conveniently and quickly installed on the platform. This design simplifies the installation steps, improves the installation efficiency, and ensures the stability and safety of the platform door. Moreover, by setting the relative positions of the side slots and the slots, and the plug-in connection method between the plug-in plates in the fixing mechanism and them, the platform door can be firmly fixed. This design not only enhances the stability of the platform door, but also effectively prevents the platform door from shaking or shifting during use, thereby ensuring the safety of passengers. Two side slots are provided, and they are mirror-imaged along the length center line of the platform. This design enables the platform door to better maintain balance and stability when subjected to external forces, further improving its safety. The above-mentioned setting solves the problems of difficult alignment, complicated operation and potential safety hazards caused by the heavy weight of the platform door in the traditional bolt pile installation method, and provides a simpler, more efficient and safer solution for the installation of rail transit platform doors.

[0029] 2. The utility model provides a fixing plate, in which the first fixing hole is designed so that the fixing plate and the top rear end of the platform can be firmly connected by bolts. This design not only enhances the stability of the bottom support mechanism of the platform door, but also facilitates the fixing operation during installation and disassembly, thereby improving work efficiency. Moreover, by opening a second fixing hole on the back of the fixing plate and the back of the platform, the stability of the support mechanism is further enhanced. This double fixing design ensures that the platform door can remain stable under various circumstances and greatly reduces safety risks. The fixing plate is connected to the edge of the platform by a snap-fitting method. This design not only increases the overall stability of the structure, but also effectively prevents the platform door from shifting or shaking during use. The snap-fitting method is simple and quick, which further improves the efficiency of installation and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0036] The following describes an embodiment of the utility model based on its overall structure.

[0037] Embodiment 1;

[0038] A bottom support mechanism for a rail transit platform door, such as Figure 1-Figure 4 As shown, it includes a platform 1 and a platform door 4. A mounting groove 2 is provided in the middle of the top of the platform 1. A side groove 3 is provided on one side of the mounting groove 2, and the side groove 3 extends to the outside of the platform 1. The platform door 4 includes a main body 401. A base 404 is provided at the bottom of the main body 401. The base 404 is plugged into the mounting groove 2. A slot 405 is provided on one side of the base 404. The side groove 3 is opposite to the slot 405. A fixing mechanism 5 is provided at the back of the side groove 3. The fixing mechanism 5 includes a fixing plate 501. An inserting plate 502 is provided on the outer surface of the fixing plate 501. The inserting plate 502 is connected to the fixing plate 501. The side groove 3 and the slot 405 are plugged into each other, and the plug plate 502 is used to fix the platform door 4. The platform door 4 is plugged into the installation groove 2 through the base 404, and then fixed by inserting the plug plate 502 into the side groove 3 and the slot 405. This multiple plug-in and fixation design significantly enhances the stability of the platform door 4. The plug plate 502 not only fixes the platform door 4 from the outside of the platform 1, but also further strengthens the fixing effect from the inside by plugging into the slot 405. This structure enables the platform door 4 to withstand greater external forces and impact forces, thereby improving the safety of the platform.

[0039] See also Figure 1 , Figure 2 , Figure 3 The material of the main body 401 and the base 404 is aluminum alloy, and the material of the fixing mechanism 5 is stainless steel. Aluminum alloy has the characteristics of light weight and high strength. Therefore, the main body 401 and the base 404 are made of aluminum alloy, which can significantly reduce the overall weight of the platform door while maintaining sufficient structural strength. This is not only convenient for installation and movement, but also can reduce the long-term load-bearing pressure on the platform structure. The fixing mechanism 5 is made of stainless steel, which provides excellent corrosion resistance and strength, ensuring the stability and safety of the platform door.

[0040] See also Figure 1 , Figure 2 , Figure 3 There are two side grooves 3, which are mirror-imaged along the length center line of the platform 1. The mirror-imaged arrangement of the two side grooves 3 can ensure that the platform door can be evenly stressed and balanced during installation. This design helps prevent the platform door from tilting or twisting due to uneven stress, thereby improving the overall stability of the platform door. Balance is very important for the platform door because it is directly related to the safety of passengers and the normal operation of the platform door.

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A first fixing hole 503 is provided at the top rear end of the fixing plate 501 and the platform 1, and the two first fixing holes 503 are relatively positioned. The relative position design of the first fixing holes 503 helps to enhance the stability of the overall structure of the platform door. When the fixing bolts tightly connect the fixing plate 501 and the platform 1 together through the two relatively positioned holes, they form a solid connection point, which can effectively resist the influence of external forces on the platform door. This design improves the stability and durability of the platform door and provides passengers with a safer and more reliable riding environment. Embodiment 2:

When the fixing bolts tightly connect the fixing plate 501 and the platform 1 together through the two relatively positioned holes, they form a solid connection point that can effectively resist the influence of external forces on the platform door. This design improves the stability and durability of the platform door and provides passengers with a safer and more reliable riding environment.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4The first fixing hole 503 and the second fixing hole 504 are both threadedly connected with fixing bolts, and the fixing plate 501 and the platform 1 are detachably connected by the fixing bolts. The detachable connection method makes the connection between the fixing plate 501 and the platform 1 more flexible. When the platform door needs to be repaired, replaced or upgraded, the staff can easily remove the fixing bolts to easily separate the fixing plate and the platform. This design not only simplifies the maintenance process, improves work efficiency, but also reduces maintenance costs. At the same time, it also provides convenience for future upgrades and renovations of the platform door.

[0044] See also Figure 1 , Figure 2 , Figure 3 The fixing plate 501 is snap-fitted to the edge of the platform 1. The snap-fit ​​design makes the installation of the fixing plate 501 simple and quick. Compared with traditional bolt connection or welding, the snap-fit ​​method does not require complicated tools and cumbersome operating steps, and the installation of the fixing plate can be completed quickly. This not only improves the installation efficiency, but also reduces the installation cost, which brings convenience to the installation and maintenance of rail transit platform doors.

[0045] See also Figure 1 , Figure 2 , Figure 3 A movable groove 402 is provided inside the main body 401, and a movable door 403 is slidably connected inside the movable groove 402. Since the movable door 403 is connected to the movable groove 402 by sliding, this structure is relatively simple and easy to disassemble. Once the movable door fails or needs to be cleaned, the staff can easily take the door out of the movable groove for repair or cleaning without large-scale disassembly of the entire platform door, thereby greatly reducing the maintenance cost and difficulty.

[0046] See also Figure 1 , Figure 2 , Figure 3 A warning light 406 is provided on the top of the main body 401. The warning light 406 is used to prompt the switch of the movable door 403.
