Description

Technical Field

[0001] This utility model relates to the field of subway platform door technology, specifically to an anti-collision subway platform door. Background Technology

[0002] Railways are high-speed, high-capacity, electrically powered rail transit systems built in cities. Trains run on fully enclosed tracks. Lines in the city center are mostly located in underground tunnels, while lines outside the city center are generally located on elevated bridges or at ground level. Subways are urban rail transit systems that encompass various underground and above-ground right-of-way areas in urban areas, characterized by high density and high capacity. While existing subway platform doors can provide some isolation, they lack effective anti-collision designs and cannot effectively reduce injuries caused by collisions. On subway platforms, crowding and collisions are prone to occur when passengers get on and off the train, especially during peak hours, when this risk is even more pronounced. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide an anti-collision subway platform door, which has the advantage of preventing damage to the main body of the platform door from collisions. It solves the problem that although existing subway platform doors can play a certain role in isolation, they lack effective anti-collision design and cannot effectively reduce the damage caused by collisions. On subway platforms, crowding and collisions are prone to occur when passengers get on and off the train, especially during peak hours, when this risk is more prominent.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a collision-resistant subway platform door, comprising an upper beam, a lower beam, and a platform door body. The upper beam is located at the top of the platform door body, and the lower beam is located at the bottom of the platform door body. Movable plates are movably connected to both the top and bottom of the upper beam. A collision-resistant plate is fixedly connected to the inner side of the movable plate, and a side plate is fixedly connected to the outer side of the collision-resistant plate. The top and bottom of the side plate are fixedly connected to the inner side of the movable plate. Two sliding components are fixedly connected to both the top and bottom of the movable plate. Rolling mechanisms are provided at both the top and bottom of the outer side of the platform door body.

[0005] In a preferred embodiment of this invention, the sliding component includes a sliding plate, and two sliding grooves are provided at the bottom of the upper beam and the top of the lower beam, with the surface of the sliding plate slidably connected to the inner wall of the sliding groove.

[0006] In a preferred embodiment of this invention, the rolling mechanism includes a mounting groove, an mounting base is fixedly connected to the inner side of the inner wall of the mounting groove, and a roller is movably connected to the inner wall of the mounting base via a pivot pin.

[0007] As a preferred embodiment of this utility model, guide rods are fixedly connected to the four corners of the rear side of the platform door body, and four movable slots are opened on the inner side of the anti-collision plate. The other end of the guide rod passes through the anti-collision plate and extends into the interior of the movable slot, and the guide rod is movably connected to the anti-collision plate.

[0008] As a preferred embodiment of this utility model, the top and bottom of the inner side of the side plate are provided with rolling grooves, the surface of the roller is movably connected to the inner wall of the rolling groove, the surface of the guide rod is fixedly connected to a limiting ring, and the surface of the limiting ring is movably connected to the inner wall of the movable groove.

[0009] As a preferred embodiment of this utility model, a shock-absorbing brick is fixedly connected to the rear side of the platform door body, and a fitting groove is provided on the front side of the anti-collision plate.

[0010] As a preferred embodiment of this utility model, the bottom and top of the platform door body are provided with anti-wear grooves, and a warning plate is embedded on the front side of the platform door body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up anti-collision plates and side plates, allows the anti-collision plates to act as a buffer when the platform door body moves backward and comes into contact with the anti-collision plates after a collision. The side plates can guide the platform door body moving forward and backward. This solves the problem that although existing subway platform doors can play a certain role in isolation, they lack effective anti-collision design and cannot effectively reduce the damage caused by collisions. On subway platforms, crowding and collisions are prone to occur when passengers get on and off the train, especially during peak hours, and this risk is more prominent. This invention achieves the effect of avoiding damage to the platform door body from collisions.

[0013] 2. By setting up a sliding component, the left and right movement of the anti-collision plate can drive the movable plate to move left and right. The left and right movement of the movable plate can drive the slide plate to slide left and right inside the slide groove. The slide groove can limit the front, back, up and down movement of the movable plate and the anti-collision plate, thereby improving the stability of the movement of the movable plate.

[0014] 3. By setting up a rolling mechanism, the mounting groove can fix and limit the mounting seat, and the roller can be movably connected by the axle pin. The front and back movement of the platform door body can drive the roller to roll on the inside of the side plate, thereby improving the front and back movement efficiency of the platform door body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a collision-resistant subway platform door, including an upper beam 1, a lower beam 2, and a platform door body 3. The upper beam 1 is located at the top of the platform door body 3, and the lower beam 2 is located at the bottom of the platform door body 3. Movable plates 4 are movably connected to the top and bottom of the upper beam 1. A collision-resistant plate 5 is fixedly connected to the inner side of the movable plate 4, and a side plate 6 is fixedly connected to the outer side of the collision-resistant plate 5. The top and bottom of the side plate 6 are fixedly connected to the inner side of the movable plate 4. Two sliding components 7 are fixedly connected to the top and bottom of the movable plate 4. Rolling mechanisms 8 are provided on the top and bottom of the outer side of the platform door body 3.

[0022] refer to Figure 2 The sliding component 7 includes a slide plate 71. Two grooves 72 are provided at the bottom of the upper beam 1 and the top of the lower beam 2. The surface of the slide plate 71 is slidably connected to the inner wall of the groove 72.

[0023] As a technical optimization of this utility model, by setting the sliding component 7, the left and right movement of the anti-collision plate 5 can drive the movable plate 4 to move left and right. The left and right movement of the movable plate 4 can drive the slide plate 71 to slide left and right inside the slide groove 72. The slide groove 72 can limit the movement of the movable plate 4 and the anti-collision plate 5 in front, back, up and down, thereby improving the stability of the movement of the movable plate 4.

[0024] refer to Figure 3The rolling mechanism 8 includes a mounting groove 81, and a mounting seat 82 is fixedly connected to the inner side of the inner wall of the mounting groove 81. A roller 83 is movably connected to the inner wall of the mounting seat 82 through a shaft pin.

[0025] As a technical optimization of this utility model, by setting a rolling mechanism 8, the mounting groove 81 can fix and limit the mounting seat 82, and the roller 83 can be movably connected by the axle pin. The back and forth movement of the platform door body 3 can drive the roller 83 to roll on the inside of the side plate 6, thereby improving the back and forth movement efficiency of the platform door body 3.

[0026] refer to Figure 3 and Figure 4 Guide rods 9 are fixedly connected to the four corners of the rear side of the platform door body 3. Four movable slots 10 are opened on the inner side of the anti-collision plate 5. The other end of the guide rod 9 passes through the anti-collision plate 5 and extends into the interior of the movable slot 10. The guide rod 9 is movably connected to the anti-collision plate 5.

[0027] As a technical optimization of this utility model, by setting a guide rod 9 and a movable groove 10, the movable groove 10 can limit the guide rod 9 in the up, down, left and right directions. The up, down, left and right limit of the guide rod 9 can limit the platform door body 3 in the up, down, left and right directions, thereby improving the stability of the movement of the platform door body 3, and at the same time facilitating the stable movement of the shock-absorbing brick 13 into the interior of the fitting groove 14.

[0028] refer to Figure 3 and Figure 4 The top and bottom of the inner side of the side plate 6 are provided with roller grooves 11. The surface of the roller 83 is movably connected to the inner wall of the roller groove 11. The surface of the guide rod 9 is fixedly connected to the limit ring 12. The surface of the limit ring 12 is movably connected to the inner wall of the movable groove 10.

[0029] As a technical optimization of this utility model, by setting the groove 11 and the limiting ring 12, the groove 11 can limit the movement of the roller 83, thereby improving the rolling stability of the roller 83, and the limiting ring 12 can limit the guide rod 9, thereby preventing the guide rod 9 from separating from the anti-collision plate 5.

[0030] refer to Figure 3 and Figure 4 The platform door body 3 is fixedly connected to the rear side with shock-absorbing bricks 13, and the front side of the anti-collision plate 5 is provided with a fitting groove 14.

[0031] As a technical optimization of this utility model, by setting up shock-absorbing bricks 13 and fitting grooves 14, the platform door body 3 can move backward to drive the shock-absorbing bricks 13 to move into the interior of the fitting grooves 14. At this time, the shock-absorbing bricks 13 can play a role in shock absorption and anti-collision for the platform door body 3.

[0032] refer to Figure 3The bottom and top of the platform door body 3 are provided with anti-wear grooves 15, and a warning plate 16 is embedded on the front side of the platform door body 3.

[0033] As a technical optimization of this utility model, by setting the anti-wear groove 15 and the warning plate 16, the anti-wear groove 15 can reduce the friction between the platform door body 3 and the platform door body 3 when it is moved by a collision, and the warning plate 16 can be set with prompt text to remind pedestrians to pay attention to safety and prevent collisions.

[0034] The working principle and usage process of this utility model are as follows: When the platform screen door body 3 is impacted by an external force, the platform screen door body 3 moves backward. At the same time, the movement of the platform screen door body 3 can drive the shock-absorbing brick 13 to move backward. When the shock-absorbing brick 13 moves into the interior of the fitting groove 14, it can play a role in shock absorption and anti-collision for the platform screen door body 3. The anti-collision plate 5 can separate the platform screen door body 3 from the subway to avoid safety accidents. At this time, the guide rod 9 can guide the platform screen door body 3. The roller 83 can improve the movement efficiency of the platform screen door body 3. Meanwhile, the surface of the warning plate 16 can be set with warning text to remind pedestrians to pay attention to safety and prevent collisions, which plays a certain anti-collision effect on the platform screen door body 3.

[0035] In summary, this type of anti-collision subway platform door, by setting up anti-collision plate 5 and side plate 6, can buffer the impact when the platform door body 3 is impacted and moves backward to contact the anti-collision plate 5. The side plate 6 can guide the platform door body 3 moving forward and backward. This solves the problem that although existing subway platform doors can play a certain role in isolation, they lack effective anti-collision design and cannot effectively reduce the damage caused by collisions. On subway platforms, crowding and collisions are prone to occur when passengers get on and off the train, especially during peak hours, when this risk is more prominent.
