[0030] The purpose of this application is to overcome the above technical deficiencies and propose a detection device for an elevator triangular lock and an elevator landing door system, so as to solve the technical problems of the lack of early warning and monitoring means and the existence of safety risks in the prior art.

[0031] To achieve the above technical objectives, this application adopts the following technical solutions:

[0032] In a first aspect, this application provides a detection device for an elevator triangular lock, as Figure 1 and Figure 2 shown, Figure 1 is a schematic structural diagram of a detection device for an elevator triangular lock provided by an embodiment of this application;

[0033] Figure 2 is a side view of a detection device for an elevator triangular lock provided by an embodiment of this application.

[0034] A detection device for an elevator triangular lock, used to detect the on-off state of the elevator triangular lock 1, includes a reed switch sensor 2, a driving member 3, and a magnetic member 4:

[0035] The reed switch sensor 2 is spaced apart from the elevator triangular lock 1;

[0036] The driving member 3 is rotatably connected to the elevator triangular lock 1, and the rotation trajectory of the driving member 3 passes through the reed switch sensor 2; and

[0037] The magnetic member 4 is attached to one side surface of the driving member 3 facing the reed switch sensor 2.

[0038] In the embodiment of the present application, a magnetic member 4 is provided on the driving member 3, and a magnetic reed sensor 2 is provided on the rotation trajectory of the driving member 3. When using a triangular key to open the triangular lock, the driving member 3 of the triangular lock approaches the magnetic reed sensor 2. When the magnetic force of the external magnetic field generated by the magnetic member 4 on the driving member 3 reaches the elastic force of the reed of the magnetic reed switch, the reed of the magnetic reed switch is attracted and the circuit is turned on. During the continuous opening of the landing door, the circuit remains continuously turned on, causing the elevator to be self-locked and in the maintenance state to ensure the personal safety of maintenance personnel. Through the cooperation of the circuit with warning, positioning management and other measures, this embodiment can timely warn operators and is beneficial to reducing or avoiding accidents; this structure is simple and reliable, with mature technology, and is suitable for the on-site addition of reused elevators; this structure does not require connecting to the communication and electrical wiring of the elevator system, does not change the original wiring and software of the elevator, and is suitable for engineering units to monitor the use and management of special elevator keys; the system event information collection and digital information storage have positive significance for retaining evidence of the safe operation status of the elevator.

[0039] In some embodiments of the present application, the first end of the driving member 3 is connected to the rotation shaft of the elevator triangular lock 1, and the rotation trajectory of the second end of the driving member 3 is centered on the rotation shaft of the elevator triangular lock 1.

[0040] In this embodiment, a magnetic member 4 (for identity identification) is added to the driving member 3 of the triangular lock, a magnetic reed sensor 2 is arranged on one side of the action direction of the driving member 3, the magnetic reed sensor 2 is connected to a positioning management unit 6 through an electrical signal, and the positioning management unit 6 controls an alarm device 8.

[0041] When using a triangular key to open the triangular lock, the driving member 3 of the triangular lock approaches the magnetic reed sensor 2. When the magnetic force of the external magnetic field generated by the magnetic member 4 on the driving member 3 reaches the elastic force of the reed of the magnetic reed switch, the reed of the magnetic reed switch is attracted and the circuit is turned on. During the continuous opening of the landing door, the circuit remains continuously turned on.

[0042] One end of the driving member 3 is fixedly connected to the rotation shaft of the elevator triangular lock 1, so that the driving member 3 rotates synchronously with the triangular lock. The other end (the second end) of the driving member 3 moves in a circular motion centered on the rotation shaft when the triangular lock rotates. When using a triangular key to rotate the elevator triangular lock 1, the driving member 3 rotates with the rotation of the triangular lock. When the driving member 3 rotates, the fixed magnetic member 4 on it will move along a circular trajectory and approach the magnetic reed sensor 2 at a certain moment. When the magnetic member 4 is close enough to the magnetic reed sensor 2, the generated magnetic field will attract the reed of the magnetic reed switch, making the circuit turn on. After the circuit is turned on, it can trigger an alarm, recording or the elevator safety system, indicating that the elevator triangular lock 1 has been opened.

[0043] The driving member 3 is directly connected to the rotating shaft of the triangular lock, ensuring that the rotation of the driving member 3 is synchronized with the opening action of the triangular lock, and improving the accuracy of detection.

[0044] Since the rotation trajectory of the driving member 3 is fixed, the reed switch sensor 2 can accurately detect the approach of the magnetic member 4, thereby reliably triggering the switch action.

[0045] As Figure 3 shown, Figure 3 is a connection schematic diagram of a detection device for an elevator triangular lock provided by an embodiment of the present application.

[0046] In some embodiments of the present application, a positioning management unit 6 is further included. The positioning management unit 6 is electrically connected to the reed switch sensor 2. When the magnetic member 4 abuts against the reed switch sensor 2, the positioning management unit 6 is turned on; when the magnetic member 4 is spaced from the reed switch sensor 2, the positioning management unit 6 is turned off.

[0047] In this embodiment, the electrical signals generated by the above action process are converted through analog-to-digital conversion, and the collected digital signals are received by the positioning management unit 6. The positioning management unit 6 defaults that an event has occurred and controls the alarm auditory and visual signals set at nearby positions to emit warning signals.

[0048] The positioning management unit 6 is connected to the reed switch sensor 2 through a circuit and can receive the signals transmitted by the reed switch sensor 2.

[0049] When the elevator triangular lock 1 is in the locked state, the magnetic member 4 on the driving member 3 maintains a certain distance from the reed switch sensor 2, and the reed switch sensor 2 is in the off state. Therefore, the positioning management unit 6 is also in the off state.

[0050] When using the triangular key to open the elevator triangular lock 1, the driving member 3 rotates, and the magnetic member 4 moves accordingly and gradually approaches the reed switch sensor 2.

[0051] When the magnetic member 4 is close enough to the reed switch sensor 2, the reed switch sensor 2 is triggered, and its reed is attracted and the circuit is turned on.

[0052] After the circuit of the reed switch sensor 2 is turned on, the positioning management unit 6 is also turned on, indicating that the magnetic member 4 has abutted against the reed switch sensor 2.

[0053] When the positioning management unit 6 is turned on, it can trigger the safety warning system to remind the maintenance personnel or management personnel that the elevator triangular lock 1 has been opened.

[0054] The positioning management unit 6 can record the opening and closing times of the elevator triangular lock 1, which is helpful for historical data analysis and management.

[0055] By integrating into a wider monitoring system, the positioning management unit 6 can achieve remote monitoring of the status of the elevator triangular lock 1, facilitating centralized management.

[0056] In some embodiments of the present application, the reed switch sensor 2 includes a reed switch, leads, and a housing. The housing is sleeved outside the reed switch. The reed switch is electrically connected to the positioning management unit 6 through the leads. The extending direction of the reed of the reed switch faces away from the magnetic member 4.

[0057] In some embodiments of the present application, the reed switch is of the normally open type.

[0058] When the triangular lock is reset and the landing door is fully closed, at this time, the driving member 3 of the triangular key leaves the reed switch, the external magnetic field force disappears, the reeds of the reed switch separate, and the circuit is disconnected.

[0059] The system software enters the next cycle and initializes.

[0060] The reed switch is of the normally open type (NO), which means that when there is no external magnetic field, the reeds of the reed switch are separated and the circuit is in an open state.

[0061] When the magnetic member 4 is close enough to the reed switch sensor 2 so that the magnetic field strength is sufficient to overcome the elastic force of the reeds, the reeds of the reed switch are attracted and the circuit is turned on.

[0062] After the circuit is turned on, the reed switch transmits a signal to the positioning management unit 6 through the leads, and the positioning management unit 6 is thus turned on, indicating that the elevator triangular lock 1 has been opened.

[0063] The landing door 5 is closed, the triangular lock is re-locked, the magnetic member 4 moves away from the reed switch sensor 2, the reeds of the reed switch return to the separated state, the circuit is disconnected, and the positioning management unit 6 is also disconnected accordingly.

[0064] The normally open reed switch remains in the open state when there is no magnetic field and is only turned on when the magnetic member 4 approaches, which improves the safety of the system and prevents false triggering.

[0065] The reeds of the reed switch face away from the magnetic member 4, reducing false operations caused by magnetic field fluctuations or external interference.

[0066] The presence of the housing protects the reed switch from dust, humidity, and physical impact, extending the service life of the sensor.

[0067] In some embodiments of the present application, the positioning management unit 6 includes a positioning chip, a storage chip, a digital-to-analog converter, and a general interface. The reed switch sensor 2 is electrically connected to the positioning chip, the storage chip, the digital-to-analog converter, and the general interface.

[0068] In some embodiments of the present application, a control module 7 and an alarm device 8 are further included. The control module 7 is electrically connected to the general interface, and the alarm device 8 is signal-connected to the control module 7.

[0069] In some embodiments of the present application, a communication module 9 and a remote management platform 10 are further included. The communication module 9 is electrically connected to the general interface, and the remote management platform 10 is signal-connected to the communication module 9.

[0070] In this embodiment, the positioning management unit 6 includes a positioning and storage chip, a digital-to-analog converter, and a GPIO interface. When the reed switch operates, an alarm device 8 installed near the landing door is controlled to emit audible and visual signals.

[0071] The circuit is turned on, and an electrical signal is sent to the positioning management unit 6. Through digital-to-analog conversion, the position information of the opened landing door and the time occurrence information are recorded and stored by the positioning management unit 6. The control module 7 of the system sends an instruction to the alarm device 8, and the alarm device 8 emits audible and visual signals. The communication module 9 reports event data to the remote management platform 10, which can be used for information storage and remote monitoring.

[0072] The circuit is turned off, and the system software controls the termination of the alarm signal. The system waits for the next cycle.

[0073] The positioning chip is used to determine the position information of the elevator triangular lock 1. The storage chip is used to store the unlocking records and timestamps of the elevator triangular lock 1. The digital-to-analog converter converts the analog signal of the reed switch sensor 2 into a digital signal for easy processing and transmission. The general interface serves as a bridge connecting the reed switch sensor 2 with other units (such as the control module 7 and the communication module 9).

[0074] The control module 7 is electrically connected to the general interface, receives signals from the positioning management unit 6, and processes them according to preset logic. The alarm device 8 is signal-connected to the control module 7. When an abnormal unlocking behavior is detected, the control module 7 will trigger the alarm device 8 to emit an alarm.

[0075] The communication module 9 is electrically connected to the general interface and is used to send the status information of the elevator triangular lock 1 to the remote management platform 10. The remote management platform 10 is signal-connected to the communication module 9, can monitor the status of the elevator triangular lock 1 in real time, and receive alarm information from the elevator.

[0076] During the use of the elevator, the opening of the landing door triangular lock poses a great safety risk. Especially in power outages and dark environments, accidents of personnel falling to death caused by careless operation or unauthorized opening of the landing door occur from time to time. By adopting measures such as warning and positioning management, it is possible to timely warn the operators, which is conducive to reducing or avoiding accidents.

[0077] The existing hall door opening alarm device 8 has a complex hardware structure and high installation and maintenance costs. This structure is simple and reliable, with mature technology, and is suitable for on-site addition to existing elevators.

[0078] This system does not require communication and electrical wiring with the elevator system, and does not change the original wiring and software of the elevator. It is suitable for engineering units to monitor the use and management of special elevator keys.

[0079] The system event information collection and digital information storage are of positive significance for retaining evidence of the safe operation status of the elevator.

The elevator triangular lock 1 and the detection device for the elevator triangular lock are both provided on the landing door 5.

[0081] In some embodiments of the present application, the landing door 5 has a mounting hole, the elevator triangular lock 1 passes through the mounting hole and is connected to the landing door 5. The elevator triangular lock has a keyhole, and the keyhole faces the outside of the landing door 5. The reed switch sensor 2 in the detection device for the elevator triangular lock is located inside the landing door 5.

[0082] In this embodiment, by providing a mounting hole on the landing door 5, the elevator triangular lock 1 is in a locked state when the landing door 5 is closed, and the keyhole faces the outside of the landing door 5, enabling maintenance personnel or authorized personnel to conveniently use the triangular key to open the triangular lock from the outside of the elevator, preventing unauthorized personnel from opening the landing door, thereby improving the safety of the elevator.

[0083] In this embodiment, the reed switch sensor 2 is installed inside the landing door 5, invisible from the outside, and not affected by external environmental factors (such as dust and humidity), ensuring the reliability of detection.

[0084] By detecting the unlocking state of the elevator triangular lock 1 through the reed switch sensor 2, the safety status of the elevator can be monitored in real time, and once an abnormality is found, measures can be taken immediately.
