Description

Technical Field

[0001] This utility model relates to the field of railway platform protection technology, specifically a one-button full release device for a railway platform lifting protection device. Background Technology

[0002] To ensure the normal operation of railway trains and passenger safety, improve the waiting environment, and enhance passenger comfort, protective devices such as platform screen doors are typically installed at the edge of the platform. Platform screen doors are devices installed along the track side of the railway platform to separate the platform area from the track area. When a train arrives, the electric doors open to allow passengers to board and alight.

[0003] Most existing protective devices operate through power supply systems. When the power supply system fails or is interrupted, the protective devices cannot function properly. Furthermore, the protective effects of these devices are relatively limited and their practicality is weak.

[0004] To address the aforementioned issues, a one-button full-release device for railway platform lifting protection is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a one-button full release device for a railway platform lifting protection device, which solves the problems in the background technology that most existing protection devices operate through a power supply system, and cannot achieve normal operation when the power supply system fails or is interrupted, and the protection effect of the protection device is relatively simple and not very practical.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a one-button full-release device for a lifting protective device for railway platforms, comprising columns, with placement slots on adjacent sides of two columns, and lifting components installed in each of the two placement slots. A fixed column is connected to the outside of the lifting component, and a fixed slot is installed on adjacent sides of the two fixed columns. A motor is fixedly connected above each of the two fixed slots, and a threaded rod is fixedly connected to the output end of the motor. A lifting plate is threaded between the outer rings of the two threaded rods, and a protective folding plate is fixedly connected to the top of the lifting plate. An operating platform is fixedly connected to the right side of the right column, and a storage slot is provided on the right side of the operating platform, containing a spare battery. An infrared sensor is fixedly connected to the front side of the left fixed column.

[0007] By adopting the above technical solution, the backup battery in the storage compartment can function when the main power supply fails. The backup battery is electrically connected to the controller, motor, electric actuator, and other electrical components. When the main power supply fails, the backup battery automatically switches to power supply, ensuring that the motor and electric actuator can still work normally after the emergency button is pressed. This achieves one-button full release of the protective device, ensuring that the protective device can function normally when the power supply system fails or is interrupted.

[0008] As a further description of the above technical solution: the lifting assembly includes an electric push rod, the bottom of which is fixedly connected to the inner wall of the placement slot, and a lifting column is fixedly connected to the output end of the electric push rod, with the outer side of the lifting column fixedly connected to a fixed column.

[0009] By adopting the above technical solution, the lifting component can drive the controller to easily lift two fixed columns simultaneously.

[0010] As a further description of the above technical solution: a speaker is fixedly connected to the front side of the operating console.

[0011] By adopting the above technical solution, passengers can be reminded to pay attention to safety through loudspeakers.

[0012] As a further description of the above technical solution: the fixing column is disposed in the placement groove, and the outside of the fixing column is slidably connected to the inner wall of the placement groove.

[0013] By adopting the above technical solution, the fixed column can be raised and lowered within the placement slot.

[0014] As a further description of the above technical solution: the top of the protective folding plate is fixedly connected to a fixing plate, and both ends of the fixing plate are fixedly connected to the upper inner side of the fixing column.

[0015] By adopting the above technical solution, the protective folding plate is composed of several folding plates that are rotated and connected together, which makes it easy to fold when shrinking.

[0016] As a further description of the above technical solution: a controller is fixedly connected to the front of the top of the control panel, and an emergency button is provided at the rear of the top of the control panel.

[0017] By adopting the above technical solution, the controller can synchronously control the movement of two motors and two electric push rods.

[0018] As a further description of the above technical solution: both of the fixed columns are fixedly connected to the top of a warning light.

[0019] By adopting the above technical solution, the warning light can serve as a warning.

[0020] As a further description of the above technical solution: the lifting column is set in the placement groove, and the outside of the lifting column is slidably connected to the inner wall of the placement groove.

[0021] By adopting the above technical solution, the lifting column can be raised and lowered within the placement slot.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model provides a one-button full-release device for a railway platform lifting safety device. The rotation of the threaded rod drives the lifting plate to rise and fall, and the protective folding plate to retract and unfold. Combined with the lifting assembly, it achieves the function of lifting and protecting the platform. Furthermore, in the event of a main power failure, the backup battery automatically switches power, ensuring that the motor and electric push rod continue to operate normally after the emergency button is pressed, achieving one-button full release of the safety device. This ensures the normal operation of the safety device even when the power supply system is interrupted or fails. Simultaneously, an infrared sensor detects human signals, and in conjunction with the controller, activates a speaker to sound an alarm, alerting passengers to safety. At the same time, warning lights on the tops of the two fixed posts illuminate, providing visual warning and enhancing the protective effect. Attached Figure Description

[0028] 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.

[0029] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0030] Reference Figure 1-3 This utility model discloses a one-button full-release device for a lifting protective device on a railway platform, comprising a column 1, which serves as a support. Each of the two adjacent columns 1 has a placement groove 2, which serves as a limiting position. A lifting assembly is installed within each of the two placement grooves 2, and a fixed column 5 is connected to the outside of the lifting assembly. Each of the two fixed columns 5 has a fixed groove 6 on its adjacent side, which serves as a limiting and guiding position. A motor 7 is fixedly connected above each of the two fixed grooves 6, and a threaded rod 8 is fixedly connected to the output end of the motor 7, allowing the motor 7 to drive the threaded rod 8 to rotate. A lifting plate 9 is threadedly connected between the outer rings of the two threaded rods 8, allowing the lifting plate 9 to rise and fall when the two threaded rods 8 rotate simultaneously. A protective folding plate 11 is fixedly connected to the top of the lifting plate 9. The protective folding plate 11 is composed of several transparent folding plates that are rotatably connected and combined, facilitating folding during retraction. An operating table 12 is fixedly connected to the right side of the right column 1. A storage slot 13 is provided on the right side of the operating table 12. A spare battery 14 is installed in the storage slot 13. The spare battery 14 is electrically connected to the electrical components. An infrared sensor 19 is fixedly connected to the front side of the left fixed column 5 to monitor the area in front of the protective folding plate 11 in real time.

[0031] Reference Figure 2 The lifting assembly includes an electric push rod 3. The bottom of the electric push rod 3 is fixedly connected to the inner wall of the placement groove 2. The output end of the electric push rod 3 is fixedly connected to a lifting column 4. The outer side of the lifting column 4 is fixedly connected to a fixed column 5. The lifting column 4 is set in the placement groove 2, and the outer side of the lifting column 4 is slidably connected to the inner wall of the placement groove 2. The lifting assembly can drive the controller 15 to easily drive the two fixed columns 5 to lift at the same time.

[0032] Reference Figure 1-3A speaker 17 is fixedly connected to the front of the control panel 12, which can remind passengers to pay attention to safety. A fixed column 5 is installed in the placement slot 2, and the outside of the fixed column 5 is slidably connected to the inner wall of the placement slot 2, facilitating the raising and lowering of the fixed column 5 within the placement slot 2. A fixed plate 10 is fixedly connected to the top of the protective folding plate 11, and both ends of the fixed plate 10 are fixedly connected to the upper inner side of the fixed column 5, allowing it to fold when retracted. A controller 15 is fixedly connected to the top front of the control panel 12, which can synchronously control the movement of two motors 7 and two electric push rods 3. The controller 15 integrates a signal processing module, which generates the same control signal when it is necessary to control the synchronous rotation of the two motors 7. This signal contains instructions such as the speed and direction of the motors 7, and is transmitted to the two motors 7 simultaneously in the form of electrical or digital signals. Since the two motors 7 receive the exact same start, speed adjustment, and direction instructions, they can start rotating at the same speed and direction when their initial states are consistent, thus achieving synchronous operation. The controller 15 also sends completely identical control signals to the two electric actuators 3 through its internal multi-channel drive module, ensuring their synchronous start, stop, and speed adjustment. An emergency button 16 is located at the rear top of the control panel 12, and warning lights 18 are fixedly connected to the top of each of the two fixed columns 5, which serve as warning lights.

[0033] Working Principle: During normal use, the device is in a standard protective state. The lifting components in the placement slots 2 on the two columns 1 begin operation. After the electric push rod 3 starts, its output simultaneously drives the lifting column 4 to slide downwards within the placement slot 2. The fixed column 5, fixedly connected to the outside of the lifting column 4, also moves accordingly. By controlling the extension and retraction of the electric push rod 3, the fixed column 5 is adjusted to a suitable height. Then, the two motors 7 rotate synchronously, and the threaded rods 8 at the output ends of the motors 7 rotate accordingly. Since the threaded rods 8 are threadedly connected to the lifting plate 9, the lifting plate 9 moves downwards along the threaded rods 8 as the two threaded rods 8 rotate. When the lifting plate 9 moves downwards, the protective folding plate 11 unfolds, forming a complete protective barrier, providing protection. At this time, the infrared sensor 19 on the front side of the left fixed column 5 is in working condition, monitoring the area in front of the fixed column 5 in real time. If a passenger approaches the protective device, the infrared sensor 19 detects the human signal and transmits it to the controller 15 at the top front of the operating console 12. The controller 15 then controls the speaker 17 on the front side of the operating console 12 to sound an alarm, reminding the passenger to pay attention to safety. At the same time, the warning lights 18 on the top of the two fixed columns 5 illuminate for visual warning. In the event of a main power failure, the backup battery 14 in the storage compartment 13 comes into play. The backup battery 14 is electrically connected to the controller 15, motor 7, electric push rod 3, and other electrical components. When the main power fails, the backup battery 14 automatically switches power supply to ensure that the motor 7 and electric push rod 3 can still operate normally after the emergency button 16 is pressed. After the emergency button 16 is triggered, the signal is transmitted to the controller 15. The controller 15 first controls the motor 7 to reverse, causing the threaded rod 8 to rotate in the opposite direction, and the lifting plate 9 to rise rapidly, causing the protective folding plate 11 to fold up. At the same time, the controller 15 controls the electric push rod 3 in the lifting assembly to extend, raising the fixed column 5 and the protective folding plate 11 to a higher position as a whole. This achieves one-button full release of the protective device.
