Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to an intelligent locking structure for safety footboards on rail transit platforms. Background Technology

[0002] With the development of train and railway technology, the types of rail transit have increased, and they are widely used in long-distance land transportation and urban public transportation. To ensure the safe operation of trains, a certain distance is maintained between the train and the platform. This poses a safety hazard for passengers getting on and off the train, especially for the elderly, children, the sick, and the disabled. Therefore, special stepping stones are usually used to facilitate passengers getting on and off the train and improve traffic efficiency.

[0003] The current platform steps lack a stable locking mechanism, and are prone to displacement after frequent stepping by passengers, affecting boarding and alighting efficiency and posing safety risks. Furthermore, the existing platform steps have poor self-protection capabilities and insufficient durability, making them unsuitable for long-term, frequent use, and thus have certain limitations.

[0004] To address this, a smart locking structure for safety footboards on rail transit platforms is proposed. Utility Model Content

[0031] like Figures 1 to 6 As shown, a specific embodiment of this utility model provides an intelligent locking structure for a safety pedal on a rail transit platform, including a safety pedal base 1, with an opening at the upper end of the safety pedal base 1, and a moving component, a locking component, and a control component disposed in the inner cavity of the safety pedal base 1;

[0032] The moving component includes a track base 2 and a worm gear ball screw 3 disposed inside the track base 2. A pedestrian step 4 is slidably disposed on the side wall of the worm gear ball screw 3. The track base 2 is symmetrically fixedly disposed on the lower wall of the inner cavity of the safety step base 1.

[0033] The locking assembly includes a slide base 5 and a locking slider 6 that is slidably disposed on the inner wall of the slide base 5.

[0035] By adopting the above technical solution, this utility model solves the problem of passengers easily falling when getting on and off the train by having the lower end of the pedestrian step 4 contact the ground. The moving component is structurally optimized and integrated with the safety step base 1. Compared with the traditional manual placement, it can adapt to the installation settings in various environments and is not easy to shift, which greatly reduces the problem of position displacement when stepping. The locking component can lock in time after the pedestrian step 4 is extended and retracted, which solves the problem of lacking a stable locking mechanism. The control component can control the extension and locking of the pedestrian step 4 in real time according to the train's arrival at the station, realizing the effect of extending when the door is open and retracting when the door is closed.

[0036] Specifically, such as Figure 1 As shown, the safety step base 1 is fixedly installed in the groove of the rail transit platform 10. Reflection sensors 11 are fixedly installed on the side walls of the rail transit platform 10 on both sides of the pedestrian step 4. Reflectors 12 are fixedly installed on both sides of the train door opposite the reflection sensors 11.

A multi-view vision camera 13 is installed on the side wall of the rail transit platform 10 to identify the outline of the door and the position of the step in real time, calculate the deviation, and ensure that the pedestrian step 4 is within the outline of the train door to avoid the pedestrian step 4 from extending out and affecting the safety of train operation.

[0038] Specifically, such as Figure 4 As shown, a drive shaft 14 is meshed on one side of the worm gear ball screw 3. The drive shaft 14 is fixedly mounted on the lower wall of the inner cavity of the safety pedal base 1. A drive motor 15 is detachably mounted in the motor mounting groove on the lower wall of the inner cavity of the safety pedal base 1. The drive motor 15 is meshed with the worm gear in the middle of the drive shaft 14.

[0039] By adopting the above technical solution, a drive motor 15 is detachably installed in the motor fixing groove on the lower wall of the inner cavity of the safety pedal base 1, which not only controls the extension and retraction of the pedestrian pedal 4, but also facilitates manual replacement and maintenance in the future.

[0040] Specifically, such as Figure 4 and Figure 5 As shown, the PLC controller 9 is electrically connected to the electromagnet device 8, the reflection sensor 11, the multi-view vision camera 13, and the drive motor 15.

[0042] Specifically, such as Figure 1 and Figure 5 As shown, the electromagnet device 8 is used to control the attraction and locking of the iron block of the slider 6, and transmits the on / off data to the PLC controller 9 in the form of an electrical signal. The reflection sensor 11 is used to detect the reflection signal from the reflector 12 in real time and transmit the reflection signal to the PLC controller 9. The multi-view vision camera 13 is used to identify the outline of the car door and the position of the pedestrian step 4 in real time, calculate the deviation, and transmit the calculated data to the PLC controller 9. The PLC controller 9 is used to analyze the data transmitted by each sensor and transmit the processed signal to the drive motor 15.

[0043] By adopting the above technical solution, the real-time detection feedback signals from the multi-view vision camera 13 and the reflection sensor 11 are sent to the PLC controller 9, which then processes and reacts to control the engagement of the electromagnet device 8 and the rotation of the drive motor 15.

[0044] Specifically, such as Figure 1 and Figure 5 As shown, the PLC controller 9 is a Siemens S7-1200, the electromagnet device 8 is a Magnet-Schultz MSH, the reflection sensor 11 is an E3Z-D6, and the multi-view vision camera 13 is a SICKTriSpector1000.

[0045] By adopting the above technical solutions, the sensors and controllers can work together precisely to achieve rapid processing and response in different environments.

A safety pedal sealing cover 17 is provided on the safety pedal base 1, which effectively reduces the entry of dust and rainwater.

[0048] Specifically, such as Figure 1As shown, the pedestrian step 4 has an anti-slip structure and is coated with a layer of rubber.

[0049] By adopting the above technical solution, the pedestrian step 4 is equipped with an anti-slip structure and coated with a layer of rubber, which greatly increases the friction resistance and prevents passengers from easily slipping due to extreme weather such as rain and snow.

[0050] Specifically, such as Figure 4 and Figure 6 As shown, the lower side wall of the slide base 5 is provided with a square opening for drainage, the lower surface of the inner cavity of the safety pedal base 1 is provided with a groove, and the lower end of the safety pedal base 1 is provided with a circular drain outlet.
