Description

Technical Field

[0001] The present application relates to the technical field of door leaf locking, and in particular to a protection device for a door leaf locking system of a subway protective door. Background Art

[0002] Currently, in urban rail transit construction, subway platforms are commonly equipped with protective door systems to ensure public safety and meet emergency response needs. These systems typically consist of door frames, door leaves, and locking mechanisms, with the safety and reliability of the locking mechanisms being crucial to the entire protection system.

[0003] Existing solutions primarily include spring-loaded, hydraulic, and electromagnetic locking mechanisms. Spring-loaded locking mechanisms utilize spring force for rapid closing, but are susceptible to deformation due to prolonged stress. Hydraulic locking mechanisms rely on hydraulic power, providing a strong closing force, but in extreme cases, hydraulic fluid leakage can lead to loss of locking function. Electromagnetic locking mechanisms rely on electricity, and while they react quickly, they fail to function properly in power outages, increasing safety risks. Furthermore, these common locking mechanisms often present challenges such as high maintenance complexity and short service lives.

[0004] Although the above-mentioned common locking mechanisms each have their own characteristics, they also have obvious shortcomings. First, due to their complex structure, they often require regular maintenance during actual use, which increases operating costs. Second, most of them lack effective self-protection mechanisms. Once they encounter emergencies (such as natural disasters such as earthquakes and fires), it is difficult to ensure continuous and reliable locking performance. Finally, they are not adequately designed for the special vibration characteristics of the subway environment, which can easily cause locking failures and endanger the lives of passengers.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0030] Reference Figure 1-4 A protection device for the locking system of a subway protective door comprises a supporting frame 1, a shock-absorbing gasket 2 is fixedly installed on the bottom of the supporting frame 1, a door leaf body 4 is rotatably connected to the inner wall of the supporting frame 1, a linkage arm 5 is fixedly installed on the outer side of the door leaf body 4, and two output ends of the linkage arm 5 are respectively fixedly connected to a secondary lock body 6 and a main lock body 7, a miniature air pressure sensor 9 and a temperature sensor 10 are fixedly installed in the inner cavity of the main lock body 7, a small hydraulic system 11 is fixedly installed in the inner cavity of the secondary lock body 6, and a monitoring camera 13 is fixedly installed on the outer side of the supporting frame 1.

[0031] See Figure 1 A number of positioning holes 3 are provided at the bottom of the shock-absorbing gasket 2, and a number of positioning holes 3 pass through the shock-absorbing gasket 2 to the inner wall of the supporting frame 1. The positioning holes 3 match the embedded parts of the subway platform foundation, so that the shock-absorbing gasket 2 can effectively absorb the impact force from the outside world, and the positioning holes 3 can facilitate the precise installation between the supporting frame 1 and the platform.

[0032] See Figure 3 and Figure 4 The outside of the main lock body 7 and the auxiliary lock body 6 are rotatably connected with an inspection plate 8, so that the inspection plate 8 can be used to seal the outside of the main lock body 7 and the auxiliary lock body 6, thereby ensuring that foreign objects from the outside will not enter the interior. Opening the inspection plate 8 facilitates the inspection and maintenance of the equipment in the inner cavity of the main lock body 7 and the auxiliary lock body 6.

[0033] See Figure 3 and Figure 4A magnetic strip 12 is fixedly installed on the side of the inspection panel 8 close to the auxiliary lock body 6 and the main lock body 7. A card slot that matches the shape and position of the magnetic strip 12 is opened on the side of the auxiliary lock body 6 and the main lock body 7 close to the inspection panel 8. The auxiliary lock body 6 and the main lock body 7 are both made of magnetic materials, so that the magnetic strip 12 can be stably adsorbed on the inner wall of the card slot by using the magnetic attraction principle, and then the inspection panel 8 can be stably connected to the auxiliary lock body 6 and the main lock body 7, thereby ensuring that the inner cavity of the auxiliary lock body 6 and the main lock body 7 is in a sealed state.

[0034] See Figure 2 and Figure 3 The outer side of the door body 4 is fixed with a fixed cover 14 by several symmetrically arranged bolts 15, and the linkage arm 5 is arranged in the inner cavity of the fixed cover 14, so that the linkage arm 5 can be stably installed on the outer side of the door body 4 using the fixed cover 14 and several bolts 15, thereby ensuring that the door body 4 will not shake easily during operation.

[0035] See Figure 3 The auxiliary lock body 6 and the main lock body 7 are both inserted into the inner side of the support frame 1 on the side away from the linkage arm 5, so that the auxiliary lock body 6 and the main lock body 7 can be used to firmly connect the support frame 1 and the door leaf body 4. The main lock body 7 has the function of directly closing the door leaf, and the auxiliary lock body 6 serves as the second line of defense to enhance the overall safety.

[0036] See Figure 1 The supporting frame 1 is welded from 6061-T6 aluminum alloy plates, the diameter of the linkage arm 5 is not less than Φ25mm, the miniature air pressure sensor 9 model is SP-100 series, the temperature sensor 10 model is PT100 standard resistance type, and the small hydraulic system 11 specification is YH25-40 / 10 type. The maximum output pressure can reach 10MPa, so that the miniature air pressure sensor 9 and the temperature sensor 10 can automatically adjust the closing force under different climatic conditions to ensure that it is always in the best working state. Through the small hydraulic system 11, when the auxiliary lock body 6 cannot operate normally due to unexpected reasons, the small hydraulic system 11 immediately starts to assist in completing the locking action.

[0037] See Figure 1 The surveillance camera 13 is connected to the cloud server network through a wireless network, allowing operation and maintenance personnel to remotely monitor the working status of each door through dedicated software and provide early warning of potential fault points. Compared with the traditional manual inspection mode, this method not only greatly improves management efficiency, but also reduces the risk of human error.

[0038] Working principle: Under normal circumstances, when the door closing signal is detected, the main lock body 7 will quickly contract to generate a closing force, pushing the door leaf 4 to close in place. At this time, the driving linkage arm 5 moves synchronously to drive the secondary lock body 6 into a ready state. If a special situation occurs, such as the main lock body 7 is damaged, the micro air pressure sensor 9 and temperature sensor 10 in the main lock body 7 will promptly feedback information to the control system, triggering a backup plan, and immediately activating the small hydraulic system 11 of the secondary lock body 6 to start pressurizing, forcing the door leaf to be pushed and pulled completely closed. The shock-absorbing gasket 2 can effectively absorb the impact force from the outside, and the positioning hole 3 provided can facilitate the precise installation between the support frame 1 and the platform. By rotating the inspection plate 8 until the magnetic strip 12 is out of the inner wall position of the slot, it is convenient to inspect and maintain the components in the inner cavity of the main lock body 7 and the secondary lock body 6. The monitoring camera 13 allows the operation and maintenance personnel to remotely monitor the working status of each door through special software, and give early warning of potential fault points. Compared with the traditional manual inspection mode, this method not only greatly improves management efficiency, but also reduces the risk of human error.
