Description

Technical Field

[0001] This utility model relates to the field of subway engineering technology, specifically to a subway platform screen door edge step with an anti-slip structure. Background Technology

[0002] During rush hour or in subway stations with high passenger volume, the platforms are often crowded with pedestrians getting on and off the train. To prevent pedestrians from accidentally falling from the platform onto the tracks, most subway systems in my country are equipped with platform screen doors, which are doors that can be opened and closed between the platform and the tracks.

[0003] To facilitate the sliding of the platform screen door panels, there is often a gap between the screen door and the platform floor. This requires the installation of edge pedals to support the panels after they are closed, thus maintaining the stability of the screen door mechanism. Most of these pedals have tracks for the panels to slide along, but they lack restrictions. If the screen door system malfunctions and closes prematurely, it may trap pedestrians getting on and off the train.

[0004] Now, a novel platform edge step with an anti-slip structure for subway platform screen doors is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a subway platform edge step with an anti-slip structure to solve the problem of lack of a limiting mechanism mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a subway platform screen door edge step with an anti-slip structure, comprising a floor, an assembly groove provided at the center of the floor, and a fixing plate installed in the assembly groove, a groove provided inside the top of the fixing plate, and limit blocks fixed longitudinally on both sides of the groove, a lifting plate movably inserted longitudinally in the groove, and vertical grooves provided on both sides of the lifting plate, with threaded sleeves fixed at the bottom of the vertical grooves, a motor installed in the lower left corner of the fixing plate, a horizontal groove provided between the left and right sides of the lower part of the fixing plate, and a worm gear movably connected between the left and right sides of the rear of the horizontal groove, worm wheels movably connected longitudinally on both sides of the front of the horizontal groove, and lead screws movably connected on both sides of the lower part of the groove.

[0007] As a further technical solution of this utility model, the top end of the lead screw is embedded in the vertical groove, and the bottom end of the lead screw is fixedly connected to the worm gear.

[0008] As a further technical solution of this utility model, the right side of the output end of the motor is fixedly connected to the worm, and the worm wheels on both sides are symmetrically engaged in front of the worm.

[0009] As a further technical solution of this utility model, a storage groove is provided inside the rear of the lifting plate, and slots are provided on both sides of the storage groove. An extension plate is movably connected between the slots on both sides. Two sets of cylinders are installed in the center of the lifting plate, and an inclined surface is provided between the left and right sides of the front end of the lifting plate.

[0010] As a further technical solution of this utility model, the piston rod of the cylinder is fixedly connected to the extension plate at the rear, and the extension plate moves back and forth along the inner wall of the slot.

[0011] As a further technical solution of this utility model, the top of the floor is fixed with a shell on both sides, and a shielding door is movably connected inside the shell. The top of the fixed plate is provided with two horizontal slides on both sides, and two sets of ball bearings are movably embedded inside the slides. The top of the lifting plate is provided with a slide between the left and right sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the platform edge step of the subway platform screen door with anti-slip structure not only prevents the platform screen door from closing prematurely and prevents pedestrians from bumping into it, but also ensures the safety of the platform screen door;

[0013] (1) By inserting a lifting plate longitudinally in the groove, when the symmetrical shielding doors slide into the outer shell, the motor in the lower left corner of the fixed plate can be started and the worm gear rotated. The worm gear meshes with the worm wheels on both sides, forcing the screw rods on both sides inside the groove to rotate in place. Then the lifting plate with the threaded sleeve is lifted, allowing people to step over it and enter the carriage. The lifting plate restricts the sliding of the shielding door on both sides to prevent it from closing accidentally. After the lifting plate is finished, it is lowered into the groove before the shielding door can be closed.

[0014] (2) An extension plate is movably connected between the slots on both sides. When the lifting plate is lifted, the two sets of cylinders inside the object are also activated. The piston rod is extended and pushed out along the slot to push the extension plate, so that the extension plate overlaps between the lifting plate and the door of the subway car. This prevents the object from falling accidentally due to the gap. Pedestrians step over the ramp, the lifting plate and the extension plate to enter the car, and the same applies when getting off the train, maintaining the connection between the subway and the platform when the subway stops.

[0015] (3) By providing two horizontal slides on both sides of the top of the fixed plate and one slide between the left and right sides of the top of the lifting plate, when the shielding door moves horizontally along the inner cavity of the outer shell, the lifting plate is in the groove of the fixed plate. The two slides on the top of both sides of the fixed plate are equipped with ball bearings, which can guide the shielding door to slide smoothly into the slide, thus maintaining the normal operation of the subway protection system.

A threaded sleeve 15 is fixed at the bottom of the vertical groove 14. A motor 5 is installed in the lower left corner of the fixing plate 4. A horizontal groove 6 is provided between the left and right sides of the lower part of the fixing plate 4, and a worm gear 7 is movably connected between the left and right sides of the rear of the horizontal groove 6. Worm wheels 8 are movably connected longitudinally on both sides of the front of the horizontal groove 6. A lead screw 23 is movably connected on both sides of the lower part of the groove 9.

[0023] The top of the lead screw 23 is embedded in the vertical groove 14, the bottom of the lead screw 23 is fixedly connected to the worm wheel 8, the right side of the output end of the motor 5 is fixedly connected to the worm 7, and the two worm wheels 8 are symmetrically meshed in front of the worm 7.

[0024] Specifically, such as Figure 1 and Figure 2As shown, when the symmetrical shielding doors 11 slide into the outer shell 1, the motor 5 at the lower left corner of the fixing plate 4 can be activated and the worm gear 7 can be rotated. The worm gear 7 meshes with and pushes the worm wheels 8 on both sides, forcing the lead screws 23 on both sides inside the groove 9 to rotate in place. Then, the lifting plate 13 with the threaded sleeve 15 is lifted, allowing people to step over it and enter the carriage. The two sides of the lifting plate 13 restrict the sliding of the shielding doors 11 to prevent them from closing accidentally.

[0025] The interior of the lifting plate 13 is provided with a storage groove 20, and the two sides of the storage groove 20 are respectively provided with slots 17. An extension plate 16 is movably connected between the two slots 17. Two sets of cylinders 19 are installed in the center of the lifting plate 13. An inclined surface 18 is provided between the left and right sides of the front end of the lifting plate 13. The piston rod of the cylinder 19 is fixedly connected to the extension plate 16. The extension plate 16 moves back and forth along the inner wall of the slot 17.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, when the lifting plate 13 is lifted, the two sets of cylinders 19 inside the object are also activated at the same time. The extension plate 16 is pushed out along the slot 17 by the telescopic piston rod, so that the extension plate 16 overlaps between the lifting plate 13 and the door of the subway car, so as to prevent the object from falling accidentally due to the gap. Pedestrians enter the car after stepping over the ramp 18, the lifting plate 13 and the extension plate 16, and the same applies when getting off the train.

[0027] The top two sides of the floor 2 are respectively fixed with the outer shell 1, and the shielding door 11 is movably connected inside the outer shell 1. The top two sides of the fixed plate 4 are respectively horizontally provided with the second slide rail 22, and the second slide rail 22 is movably embedded with two sets of ball bearings 21. The top left and right sides of the lifting plate 13 are provided with the first slide rail 12.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, when the shielding door 11 moves left and right along the inner cavity of the outer shell 1, the lifting plate 13 is in the groove 9 of the fixing plate 4. The slide rails 22 on both sides of the top of the fixing plate 4 are equipped with ball bearings 21, which can guide the shielding door 11 to slide smoothly into the slide rail 12, maintaining the normal operation of the subway protection system. It can also ensure the stability of the shielding door 11 structure when the lifting plate 13 sinks.

[0030] Furthermore, the cylinder 19 includes a cylinder barrel, piston, piston rod, end cap, seal, solenoid valve, air source, and air passage. The cylinder 19 is a fully disclosed prior art, and the air source supply method is implemented in a conventional manner, so it will not be described in detail.

[0031] Working principle: When this utility model is in use, as the shielding door 11 moves left and right along the inner cavity of the outer shell 1, the lifting plate 13 is positioned in the groove 9 of the fixing plate 4. The slide rails 22 on both sides of the top of the fixing plate 4 are equipped with ball bearings 21, which guide the shielding door 11 smoothly into the slide rails 12. When the symmetrical shielding doors 11 slide into the outer shell 1, the motor 5 in the lower left corner of the fixing plate 4 is activated and the worm gear 7 is rotated. The worm gear 7 engages with and pushes the worm wheels 8 on both sides, forcing the lead screws 23 on both sides inside the groove 9 to rotate in place, thereby lifting the lifting plate 13 with the threaded sleeve 15, allowing people to... Stepping over this object to enter the carriage, the lifting plate 13 restricts the sliding of the platform screen door 11 on both sides to prevent it from closing accidentally. After the lifting plate 13 is lowered into the groove 9, the platform screen door 11 can be closed. When the lifting plate 13 is raised, the two sets of cylinders 19 inside the object are also activated, and the extension plate 16 is pushed out along the slot 17 by the telescopic piston rod. The extension plate 16 overlaps between the lifting plate 13 and the door of the subway car to prevent the object from falling accidentally due to the gap. Pedestrians enter the carriage after stepping over the ramp 18, the lifting plate 13 and the extension plate 16, and the same applies when getting off.
