Description

Technical Field

[0001] This utility model relates to the technical field of railway protection, and in particular to a railway intrusion prevention alarm device. Background Technology

[0002] In passenger stations, subway stations, and other similar platforms, to prevent waiting passengers from getting too close to the platform edge and being swept onto the railway tracks by trains, high-speed trains, or subways, thus endangering their lives, intrusion alarm devices are usually installed at the platform edge. These devices not only prevent waiting passengers from getting too close to the platform edge, but also promptly trigger an alarm if someone is found to be near the edge, alerting both the waiting passengers and staff.

[0003] In existing technologies, intrusion alarm devices typically employ a door barrier structure. Specifically, a barrier structure is installed along the edge of the platform to prevent waiting passengers from getting too close to the platform edge or falling onto the railway tracks. Multiple sliding doors are installed between the barrier structures, corresponding to the train's entrances and exits, facilitating passenger boarding and alighting. However, this structure still has some problems that need improvement during use:

[0004] 1. When the above-mentioned device is in use, it is usually fixedly installed at the edge of the platform. Therefore, when the opening and closing door of the above-mentioned device malfunctions and is under maintenance, the opening and closing door may become unusable during the maintenance period, which will prevent waiting passengers and passengers on the train from entering and exiting through the opening and closing door. If the maintenance time is long, it will be inconvenient for people to enter and exit, and may lead to overcrowding in the train and on the platform.

[0005] Therefore, there is an urgent need for an intrusion alarm device that provides good protection while not obstructing personnel access during maintenance. Utility Model Content

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0046] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0047] Furthermore, the terms “, second”, “third”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0048] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0049] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0051] It should be understood that in order to prevent waiting passengers from entering the railway, door barriers are usually fixed at the edge of the platform, such as the door barriers at the edge of the subway platform. Therefore, when the opening and closing of the above-mentioned device malfunctions and the opening and closing is being repaired, the opening and closing may become unusable during the repair period, which will prevent waiting passengers and passengers on the train from entering and exiting through the opening and closing. If the repair time is long, it will make it more inconvenient for people to enter and exit, and may lead to more congestion in the train and on the platform.

[0052] To address the aforementioned issues, this embodiment provides a railway intrusion prevention alarm device, primarily comprising multiple gate stop units 1, multiple limiting slide bars 3, and two displacement ends 4. This device protects waiting passengers from accidentally entering the railway. Furthermore, if a gate stop unit 1 malfunctions, maintenance can be performed simultaneously without obstructing the entry and exit of waiting and disembarking passengers.

[0053] In this embodiment, as Figure 1 As shown, multiple door stop units 1 are arranged sequentially at intervals along a straight line at the edge of the platform. Specifically, each door stop unit 1 includes two housings 11, which are symmetrically arranged and opposite to each other. The multiple housings 11 of the multiple door stop units 1 are arranged sequentially at intervals along a straight line at the edge of the platform.

[0054] The shell 11 can be a rectangular or cylindrical structure. In this embodiment, the shell 11 is a rectangular shape. Specifically, the outer walls of the shell 11 are perpendicular to the horizontal ground, and the lower side of the shell 11 is detachably connected to the ground.

[0055] In this embodiment, a passageway 2 is provided between the two shells 11 of the same door stop circle for workers to pass through.

[0056] In this embodiment, as Figures 1-6 As shown, the upper and lower sides of the sidewall of the housing 11 facing the passageway 2 are provided with protrusions 111. The two protrusions 111 are arranged opposite and symmetrically on the sidewall of the housing 11, and are located on the side of the sidewall of the housing 11 facing the railway. Specifically, the two protrusions 111 adopt a rectangular structure. Both protrusions 111 are perpendicular to the sidewall of the housing 11, and the upper and lower sidewalls of the two protrusions 111 are parallel to the horizontal ground. The centerlines of the upper and lower sidewalls of the two protrusions 111 are located in the same plane, and this plane is perpendicular to the sidewall of the housing 11, so that the position of the two protrusions 111 is close to the railway side.

[0057] In this embodiment, as Figure 1 As shown, a rotating stop 12 is provided between the two protrusions 111. The two ends of the rotating stop 12 are rotatably connected to the protrusions 111 respectively, and there is a gap between the two rotating stops 12, so that the two rotating stops 12 can rotate without obstructing each other. At the same time, it can also block people from entering and exiting.

[0058] The rotating stop 12 includes a rotating rod 121 and a rotating motor 122. Specifically, the rotating rod 121 has a cylindrical structure and is positioned between two protrusions 111. The axis of the rotating rod 121 is perpendicular to the horizontal ground, and the axis of the rotating rod 121 is in the same plane as the axis of the two protrusions 111. The rotating motor 122 is positioned on the upper side of the protrusion 111 on the side wall of the housing 11. One end of the rotating rod 121 is rotatably connected to the lower protrusion 111, and the other end passes through the upper protrusion 111 and is connected to the rotating motor 122. The rotating motor 122 drives the rotating rod 121 to rotate, thereby allowing the rotating rod 121 to rotate relative to the protrusion 111.

[0059] Among them, such as Figures 1-6 As shown, the rotating rod 121 has multiple stops 123 on its body. The multiple stops 123 are arranged sequentially at intervals along the axial direction of the rotating rod 121. The axial direction of the multiple stops 123 on the same rotating rod 121 is perpendicular to the axial direction of the rotating rod 121. The axes of the multiple stops 123 are all located in the same plane with the axis of the rotating rod 121. The number of multiple stops 123 on both sides of the same passageway 2 is the same, and they are arranged opposite each other and symmetrically. Specifically, the height of the two stops 123 symmetrically arranged on both sides of the same passageway 2 is the same, and one end is opposite to the other.

[0060] The device also includes a control terminal, which can be a component structure such as an electrical control cabinet, remote control, control panel, or control computer. The rotating motor 122 is electrically or wirelessly connected to the control terminal. In this embodiment, when it is necessary to block people from entering or exiting the passageway 2, multiple barriers 123 are arranged opposite each other to block people from entering or exiting the passageway 2. When people need to enter or exit the passageway 2, the control terminal controls the rotating motor 122 to rotate, causing one rotating motor 122 inside the passageway 2 to rotate 90 degrees clockwise and the other rotating motor 122 to rotate 90 degrees counterclockwise. This causes the two rotating rods 121 to rotate 90 degrees clockwise and counterclockwise respectively, thereby driving the barriers 123 on both sides of the passageway 2 to rotate 90 degrees clockwise and counterclockwise respectively, thus blocking the passageway. Multiple barriers 123 on both sides of passage 2 have one end facing the same direction and their axis is aligned with the direction in which people enter passage 2, thus opening passage 2 and allowing people to enter and exit smoothly. When people have finished boarding and alighting and the vehicle is about to leave the platform, the control terminal controls the rotating motor 122 to rotate, causing one rotating motor 122 inside passage 2 to rotate 90 degrees counterclockwise and the other rotating motor 122 to rotate 90 degrees clockwise. This causes the two rotating rods 121 to rotate 90 degrees counterclockwise and clockwise respectively, thereby driving the barriers 123 on both sides of passage 2 to rotate 90 degrees counterclockwise and clockwise respectively. Thus, the multiple barriers 123 on both sides of passage 2 are set up one-to-one to block passage 2, thereby preventing people from entering and exiting passage 2.

[0061] In this embodiment, the control terminal controls the rotating motor 122 to rotate at a fixed angle, which is existing technology and will not be described in detail.

[0062] In this embodiment, as Figure 1 As shown, two adjacent door stop units 1 are close to each other and two adjacent housings 11 are provided with multiple limiting slide rods 3. The two ends of the limiting slide rods 3 can slide through the two housings 11 respectively and are respectively set in the two passage openings 2. The axis of the limiting slide rods 3 is perpendicular to the side wall of the housing 11, so that the multiple limiting slide rods 3 can block the space between the two adjacent door stop units 1 and prevent waiting passengers from entering the railway.

[0063] Among them, such as Figure 3-Figure 8 As shown, the housing 11 is provided with a plurality of through sliding rod holes 112, and the sliding rod holes 112 are arranged sequentially at intervals along the vertical direction. The sliding rod holes 112 are adapted to the limiting sliding rods 3, so that the limiting sliding rods 3 can pass through the sliding rod holes 112 and slide along the axial direction of the sliding rod holes 112. In this embodiment, the axial direction of the sliding rod holes 112 is perpendicular to the side wall of the housing 11, and the axis of the sliding rod holes 112 is located in the same plane as the center line of the two side walls of the housing 11. This allows the axes of the plurality of limiting sliding rods 3 to pass through the center line of the side wall of the housing 11, thereby making the force on the housing 11 more uniform when it is displaced relative to the limiting sliding rods 3.

[0064] In this embodiment, as Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, the device also includes multiple displacement ends 4. Specifically, each displacement end 4 includes a support plate 41 and multiple rollers 42. The support plate 41 has multiple rollers 42 on its lower side and its upper side is adapted to the lower end of the housing 11. Both displacement ends 4 can be detachably connected to the lower ends of the housing 11 to move the housing 11.

[0065] The number of displacement ends 4 is an integer multiple of four. Specifically, the number of displacement ends 4 can be four, eight, or twelve. In this embodiment, the number of displacement ends 4 is four. When the door stop unit 1 malfunctions, two displacement ends 4 can be connected to the lower sides of the two housings 11 of the malfunctioning door stop unit 1, and then the other two displacement ends 4 can be connected to the lower sides of the housings 11 of the other two adjacent door stop units 1, so that the four housings 11 are at the same height. Then, the malfunctioning door stop unit 1 is pushed so that it moves axially toward the housing 11 of another door stop unit 1 along the limiting slide bar 3. After moving a certain distance, the displacement ends 4 are removed and then repaired. At the same time, since the housings 11 of the malfunctioning door stop unit 1 are moved toward both sides of the passageway 2, the door stop unit 1 will not block the passageway 2 from entering and exiting when it is being repaired. This avoids the situation where it is difficult for people to enter and exit when the door stop unit 1 malfunctions, thus preventing congestion in the carriage and on the platform.

[0066] In this embodiment, the housing 11 is detachably connected to the ground, and the displacement end 4 is detachably connected to the housing 11, so that the displacement end 4 can be connected to the housing 11 of the faulty door stop unit 1, thereby displacing the housing 11 along the limiting slide bar 3 toward a position away from the passageway 2, so as to facilitate the maintenance of the housing 11 and other components, and will not obstruct the entry and exit of personnel, thereby avoiding congestion of personnel in the carriage and platform.

[0067] In some embodiments, as Figure 1-Figure 5 As shown, the axial direction of the stop bar 123 is perpendicular to the side wall of the housing 11 facing the passageway 2, and one end of the stop bar 123 is threadedly connected to the rod body of the rotating rod 121, so that the stop bar 123 and the rotating rod 121 are detachable. This allows the housing 11 to be displaced, reducing its mass by removing the stop bar 123, thus making the displacement of the housing 11 easier. At the same time, the stop bar 123 can be replaced by disassembly, making the cleaning, maintenance and repair of the stop bar 123 easier, and avoiding the situation where the door stop unit 1 cannot be used normally when the stop bar 123 is being maintained.

[0068] In some embodiments, as Figures 1-6 As shown, multiple limiting slide rods 3 are perpendicular to the side wall of the housing 11, and the centerline of the side wall of the housing 11 and the axis of the limiting slide rod 3 are located in the same plane perpendicular to the side wall of the housing 11. The rotating rod 121 is set on one side of the centerline of the side wall of the housing 11 and faces the outside of the platform. Both ends of the limiting slide rod 3 are provided with nuts 5, and the side of the nuts 5 abuts against the surface of the side wall of the housing 11, thereby stabilizing the position of the limiting slide rod 3 and preventing the limiting slide rod 3 from being easily removed between the two housings 11 under normal circumstances.

[0069] In some embodiments, as Figure 6 , Figure 11 , Figure 12 and Figure 13 As shown, it also includes multiple door stop spring ropes 6. Each end face of the limiting slide bar 3 is provided with a hanging block 31, and the hanging block 31 is provided with a hanging hole 311. Each end of the door stop spring rope 6 is provided with a hook 61. The door stop spring rope 6 can be detachably connected to two limiting slide bars 3 arranged opposite each other in the same passageway 2 through the hooks 61 at both ends. Specifically, when the two shells 11 or one of the shells 11 in the same door stop unit 1 are displaced, the two ends of the multiple door stop spring ropes 6 are respectively connected to the multiple limiting slide bars 3 on both sides of the passageway 2 to form a temporary door stop structure. Since the structure of hooks 61 and hanging holes 311 is adopted, the connection and disassembly are relatively simple, so it will not consume much manpower.

[0070] In some embodiments, as Figures 1-6 As shown, the shell 11 has connecting plates 13 on both sides of its extension direction along the platform. The lower side wall surfaces of the two connecting plates 13 are parallel to the lower side wall surface of the shell 11 and are located on the same plane. The two connecting plates 13 are provided with connecting bolts 14. The shell 11 is fixed to the ground by the connecting bolts 14. The connecting bolts 14 are used to connect the shell 11 to the ground at a preset position, so that the ground is stably set on the horizontal ground.

[0071] In some embodiments, as Figures 1-6 As shown, the shell 11 has two support plates 15 on its two side walls perpendicular to the platform extension direction. Both support plates 15 are perpendicular to the side walls of the shell 11, and the lower surfaces of both support plates 15 are far from the ground. The upper surface of the support plate 41 has a groove 411, which is adapted to the end face of the lower end of the shell 11. When the support plate 41 is supported on the shell 11, the upper side walls on both sides of the groove 411 are respectively supported on the lower side walls of the two support plates 15, so that the displacement end 4 is adapted to the shell 11 and provides stable support for the shell 11.

[0072] In this embodiment, as Figures 7-10 As shown, both support plates 15 are provided with insertion holes 151. The upper side wall of the support plate 41 is provided with two insertion slots 412 corresponding to the two insertion holes 151. The two insertion slots 412 are respectively located on both sides of the groove opening of the groove 411. A removable insertion rod 8 is inserted into the insertion slot 412. The two insertion rods 8 are respectively adapted to the two insertion holes 151. When the housing 11 is displaced, the insertion rod 8 is inserted into the insertion hole and the insertion slot 412, so that the displacement is relatively stable. After the displacement is completed, the insertion rod 8 can be pulled out.

[0073] In this embodiment, as Figure 1 , Figure 3 and Figure 6As shown, a circular groove 16 is provided on the upper side of the support plate 15, and a push rod 7 is provided in the circular groove 16. The push rod 7 is adapted to the circular groove 16. When the housing 11 is displaced, the push rod 7 is inserted into the circular groove 16, which makes it easier for personnel to push the housing 11.

[0074] In some embodiments, as Figure 1 As shown, the housing 11 is equipped with a warning light 17. A detection element 9 is provided between the two adjacent housings 11 of the door stop unit 1. Specifically, a detection element 9 is provided between the opposite side walls of the two housings 11. One side wall of the housing 11 is equipped with an infrared receiver 92, and the other housing 11 is equipped with an infrared transmitter 91. The infrared receiver 92 and the infrared transmitter 91 are arranged opposite each other. The infrared transmitter 91 always emits infrared rays toward the infrared receiver 92. They are all located on the upper side of all the limit slide bars 3. The infrared receiver 92, the infrared transmitter 91, and the warning light 17 are all electrically or wirelessly connected to the control terminal. When a person climbs the limit slide bar 3 and crosses the door stop unit 1, the person blocks the space between the infrared transmitter and the infrared receiver 92. The infrared receiver 92 sends a signal to the control terminal, and the control terminal controls the warning light 17 to flash, thereby alerting the site staff and letting them know the location where the door stop device has been crossed.
