Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traffic installation devices, in particular to an anti-stepping device for gaps between urban rail transit platforms. Background Art
[0002] Because train bodies sway side to side during travel, the national standard "Metro Design Code" (GB50157-2013) stipulates that the safety gap between the platform edge and the door of a stationary vehicle should be 70 mm (for built-in or external doors) or 100 mm (for sliding doors) in straight sections. In curved sections, the clearance should be increased by no more than 80 mm to the specified value for straight sections. While this gap ensures the safe passage of trains, it also poses a risk to passengers, potentially causing their feet to be caught between the train and the platform door, resulting in personal injury.
[0003] Nowadays, most platform door thresholds are equipped with anti-stepping rubber strips. When the anti-stepping rubber strips are too wide, although they can reduce the occurrence of passengers stepping on the air, they will exceed the equipment limits required by the train too much, and there may be a risk of the strips rubbing against the vehicle during operation; when the anti-stepping rubber strips are too narrow, passengers may step on the air when getting on and off the train. When passengers are squeezed into the gap between the train and the platform door threshold, the anti-stepping rubber strips mostly need to be removed from the track area, which will bring great pressure to operations and rescue.

[0029] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0030] In the description of this utility model, if the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" appear, the directions or positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this utility model. Furthermore, if the terms "first," "second," and "third" appear, they are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0031] Example 1:
[0032] like Figure 1 、 2As shown, the support assembly is used to fill the gap between the platform 112 and the train components, providing a smooth passage for passengers. Specifically, the support assembly includes a bracket 107, a transition plate 101, and a push rod 105. Interconnecting hinged seats are provided at the upper end of the bracket 107 and at the edge of one side of the transition plate 101. The transition plate 101 and the bracket 107 are hingedly connected via hinged seats provided on their respective bodies using pins. The push rod 105 provides power for switching the transition plate 101 between the horizontal and vertical positions. An optional transmission method between the push rod 105 and the transition plate 101 is as follows: the end of the cylinder of the push rod 105 is hinged to the platform 112, and the end of the telescopic rod of the push rod 105 is hinged to the bottom of the transition plate 101 and the side of the train. When the push rod 105 is extended, the transition plate 101 moves to the horizontal position. When the push rod 105 is retracted, the transition plate 101 moves to the vertical position.
[0033] like Figure 6 As shown, the warning light 111 serves as a warning to passengers getting on and off the train. To facilitate observation by passengers getting on and off the train, the warning light 111 is arranged on the side of the transition plate 101 close to the train side. Specifically, the warning light 111 includes a base plate, and a plurality of light beads are evenly distributed on the surface of one side of the base plate.
[0034] In order to prevent the lamp beads from short-circuiting due to moisture or water, a waterproof coating is provided on the periphery of the warning light 111. The waterproof coating can be encapsulated with transparent silicone. Apply the silicone evenly on the surface of each lamp bead and the base, and cover the entire lamp bead area. After the silicone is cured, a tight protective layer can be formed. In addition, the silicone has a high transmittance to light and will not affect the luminescence of the lamp beads. A transparent acrylic cover can also be used for encapsulation. Install a customized transparent acrylic cover on top of the base, seal the edges with sealing strips or glue to ensure that the internal space is isolated from the outside world. This method can be installed and disassembled for maintenance more conveniently, and the acrylic material has good light transmittance.
[0035] like Figure 7 As shown, the control unit is used to receive signals from the dispatching system indicating train entry and exit, and to control the push rod 105 to perform actions based on the train entry and exit signal feedback, as well as to control the flashing of the indicator light 111. Specifically, the control unit is provided with a plurality of I / O interfaces. The control push rod 105 is electrically connected to the I / O interfaces of the control unit. The indicator light 111 is connected in parallel to the power supply via a relay. The control unit controls the flashing of the indicator light 111 by controlling the opening and closing of the relay.
[0036] During use, when the control unit receives a signal from the dispatching system indicating that a train has entered the station and has stopped, it sends a signal to the push rod 105, causing it to push out and move the transition plate 101 to a horizontal position. Simultaneously, the control unit sends a signal to the relay, closing it and causing the warning light 111 to flash.
[0037] When the control unit receives the train entry and exit signal from the dispatching system, it sends a signal to the push rod 105 to retract the push rod 105, so that the transition plate 101 moves to a vertical state. At the same time, the control unit sends a signal to the relay to disconnect the relay, turning off the warning light 111.
[0038] It is understandable that the functions of the control unit are realized by the control unit hardware itself and the program installed in the control unit. It should be noted that the writing of the program is based on the above-mentioned description of the working principle of the anti-stepping device for the gap between the urban rail transit platforms. Among them, when writing the program, the specific assembly language, called functions, and data debugging methods used are all existing technologies. The program installed in the control unit of this application is only a condition for the normal operation of this application and is not the content protected by this application.
[0039] In order to ensure the speed of the action and the extension and retraction range of the telescopic rod when the transition plate 101 is adjusted in the horizontal and vertical positions, the push rod 105 in this embodiment can be an electric push rod.
[0040] To ensure moisture-proof and waterproof requirements, the control unit can be installed in a 304 stainless steel box, and the box meets the IP54 requirements of GB / T4208-2017.
[0041] When the warning light 111 is connected, an aviation plug connector with a waterproof function is used for connection.
[0042] Example 2:
[0043] On the basis of Example 1, Figure 1In the illustrated embodiment, another optional method for transmission between the push rod 105 and the transition plate 101 is provided. Specifically, a slideway 106 is provided at the bracket 107. The slideway 106 is slidably connected to the slider 104 and the connecting rod 103. The two ends of the connecting rod 103 are respectively hinged to the slider 104 and the transition plate 101 through a hinge seat. During use, the push rod 105 pushes the slider 104 to move along the slideway 106 to achieve horizontal and vertical adjustment of the transition plate 101. Because the slider 104 is constrained by the slideway 106, the slider 104 has only one degree of freedom to slide along the slideway 106. Therefore, when the hinge precision of the transition plate 101 and the bracket 107 is low and there is a certain amount of clearance, the telescopic rod of the push rod 105 is prevented from being deviated from its telescopic direction due to the load of the transition plate 101, causing the telescopic rod of the push rod 105 to bend and deform.
[0044] Example 3:
[0045] On the basis of Example 2, Figure 1 In the illustrated embodiment, when passengers boarding or exiting the vehicle step on either side of the transition plate 101, in order to transmit the force exerted on the transition plate 101 to the slider 104, a secondary rod 102 extending toward the transition plate 101 is provided at the connecting rod 103. The ends of each secondary rod 102 are hingedly connected to the transition plate 101. To ensure that the mechanism's freedom of movement is unrestricted when adjusting the horizontal and vertical positions of the transition plate 101, the hinge points between each secondary rod 102 and the transition plate 101, and the hinge points between the connecting rod 103 and the transition plate 101, are collinear.
[0046] Example 4:
[0047] Based on any one of embodiments 1-3, in order to increase the friction between the surface of the transition plate 101 and the passengers getting on and off the bus, an anti-slip structure is provided on the upper portion of the transition plate 101. The anti-slip structure can be in the form of an anti-slip coating or anti-slip texture.
[0048] Example 5:
[0049] On the basis of any one of Examples 1-4, Figure 3 In the illustrated embodiment, to adapt the transition plate 101 to different gaps between platforms 112, the transition plate 101 is constructed in a split configuration, with mounting holes 108 provided on each plate. The mounting holes 108 on one plate are through-hole shaped, while the mounting holes 108 on the other plate are rounded. The two plates of the transition plate 101 are fastened together using bolts through the mounting holes 108 in their respective bodies. During installation, the bolts remain fixed to the plate containing the through-hole mounting holes 108, while the bolts slide through the rounded holes on the other plate, securing the two plates in place according to the width of the gap between the platform 112 and the train.
[0050] Example 6:
[0051] On the basis of Example 5, Figure 4 In the illustrated embodiment, to enhance the strength of each plate body of the transition plate 101 , a reinforcing rib 109 is provided on the upper surface of each plate body, and a gap is provided between the reinforcing rib 109 of any plate body and the main body of the plate body to accommodate the other plate body.
[0052] Example 7:
[0053] Based on any one of Examples 1-6, when the transition plate 101 runs to the vertical position, the connecting rod 103 or the push rod 105 and the transition plate 101 are collinear, that is, when the dead point position appears, the force exerted by the connecting rod 103 or the push rod 105 on the transition plate 101 passes through the center of rotation of the transition plate 101, and will not be able to generate an effective torque to rotate the transition plate 101 to the horizontal position.
[0054] To prevent the occurrence of a dead point, bracket 107 is equipped with a contact sensor, which is electrically connected to the control unit and provides feedback on the vertical position of transition plate 101. The contact sensor is positioned to ensure that transition plate 101 reaches its vertical position and has not yet reached a dead point when the contact sensor is triggered. Upon receiving the trigger signal from the contact sensor, the control unit issues a command to the push rod 105 to stop retraction.
[0055] The contact sensor may be in the form of a contact switch or a reed switch.
[0056] Example 8:
[0057] On the basis of any one of Examples 5-7, Figure 5 In the illustrated embodiment, in order to facilitate the installation of the warning light 111 , a slot 110 for securing the warning light 111 is provided on the plate body close to the side of the train.
[0058] The embodiments described above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention based on the technical solution and utility model concept of the present invention, which should be covered within the protection scope of the present invention.
