As the core component of the elevator safety system, the status of elevator floor door locks is directly related to the safety of elevator operation. However, in actual applications, elevator floor door locks may fail for a variety of reasons. If they are not detected and repaired in time, serious safety accidents may occur.

[0003] Traditional elevator floor door locks usually use lock hooks for fixed connection, which ensures that the elevator floor door can be firmly locked when closed to prevent it from being manually opened from the outside during the operation of the elevator. At present, the traditional elevator floor door lock fault detection method mainly relies on manual inspection and regular maintenance. This method requires maintenance personnel to regularly inspect and test the elevator floor door locks to ensure that they are working properly.

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiments of the present application disclose an elevator door lock fault detection system and method.

[0031] Reference Figure 1-Figure 3, an elevator door lock fault detection system, comprising an elevator floor door panel 1, a lock hook 2 is hinged on one side of the elevator floor door panel 1, and a mounting tube 3 is fixedly connected to one side of the elevator floor door panel 1, an elastic air bag 4 is fixedly connected inside the mounting tube 3, and an air pressure sensor 5 is fixedly connected inside the mounting tube 3, a storage slide 6 is opened at one end of the elevator floor door panel 1, a storage slide rod 7 is slidably connected inside the storage slide 6, an ejection mounting plate 8 is fixedly connected to one end of the storage slide rod 7, and a pressure sensor 9 is fixedly connected to the side of the ejection mounting plate 8 away from the inside of the storage slide 6, a transmission component for squeezing the elastic air bag 4 to produce contraction is installed at one end of the lock hook 2, and an ejection component for pushing the storage slide rod 7 to move along the length direction of the storage slide 6 is installed at one end of the lock hook 2, and an induction control component is installed on one side of the elevator floor door panel 1.

[0032] When in use, first, when the elevator floor door panel 1 is driven to close, the elevator floor door panel 1 drives the lock hook 2 to form a fixed connection with the lock buckle at one end of another elevator floor door panel 1, so that the lock hook 2 is deflected around the hinge axis by force and then resets, so that the lock hook 2 hooks the lock buckle, and at the same time, the lock hook 2 drives the transmission component to push the elastic airbag 4 to move inside the installation tube 3, thereby reducing the space inside the installation tube 3, and then increasing the air pressure inside the installation tube 3, and at the same time, an air pressure sensor 5 is set to monitor the air pressure change inside the installation tube 3 in real time; Then, when the lock hook 2 fails to hook the lock buckle, resulting in a malfunction in closing the elevator floor door panel 1, the rotation angle of the lock hook 2 around the hinge axis does not reach the set value, so that the lock hook 2 drives the transmission component to push the elastic airbag 4 into the installation tube 3. The moving distance is shortened, and the air pressure change inside the installation tube 3 does not reach the set value. At the same time, the air pressure change data inside the installation tube 3 is transmitted to the sensing control component in real time through the air pressure sensor 5 for analysis and processing, and then the sensing control component issues a warning to the staff and people close to the elevator; When the elevator floor door panel 1 is driven to drive the lock hook 2 to move closer to the other elevator floor door panel 1, and the lock hook 2 is deflected around the hinge axis under force and then reset to hook the lock buckle, the lock hook 2 drives the ejection component to push out the storage slide bar 7 along the length direction of the storage slide groove 6, and the storage slide bar 7 drives the ejection mounting plate 8 to pass through the storage slide groove 6 and move closer to the other elevator floor door panel 1. At the same time, the ejection mounting plate 8 pushes the pressure sensor 9 to form a conflict with one end of the other elevator floor door panel 1, so that the pressure sensor 9 transmits the pressure signal to the sensing control component. When the storage slide bar 7 pushes the pressure sensor 9 to move toward the other elevator floor door panel 1 along the length direction of the storage slide groove 6, and the pressure sensor 9 does not sense the pressure signal, the sensing control component determines that the two elevator floor door panels 1 are not close together and closed, thereby timely issuing a warning to the staff and the people close to the elevator, thereby facilitating the real-time monitoring of the closing and locking status of the two elevator floor door panels 1, effectively improving the monitoring efficiency of the device and reducing the operation risk of the elevator.

[0033] Reference Figure 1 and Figure 3 , Figure 4 The transmission assembly includes an eccentric wheel 10 fixedly connected to the hinged end of the lock hook 2 and the elevator floor door panel 1, a guide slide groove 11 is symmetrically opened at one end of the installation cylinder 3, a guide slide rod 12 is slidably connected inside the guide slide groove 11, and an extrusion plate 13 adapted to the eccentric wheel 10 is fixedly connected at the bottom of the two guide slide rods 12, and one end of the elastic airbag 4 extends out of the interior of the installation cylinder 3 and forms a conflict with the extrusion plate 13; The bottom of the extrusion plate 13 is rotatably connected to a contact wheel 14 , and the contact wheel 14 forms a rolling contact with the eccentric wheel 10 .

[0034] When in use, first, when the elevator floor door panel 1 is driven to close, the lock hook 2 is brought into conflict with the lock buckle, and the lock hook 2 is pushed to deflect around the hinge axis, so that the lock hook 2 drives the eccentric wheel 10 to rotate, and at the same time, the eccentric wheel 10 forms a rolling bottom with one end of the extrusion plate 13 through the conflict wheel 14, and the extrusion plate 13 pushes the guide slide bar 12 to move along the length direction of the guide slide groove 11, and at the same time, one end of the extrusion plate 13 squeezes the elastic airbag 4 into the interior of the mounting tube 3, thereby compressing the internal space of the mounting tube 3 and increasing the air pressure inside the mounting tube 3, so as to facilitate the squeezing of the elastic airbag 4 when the lock hook 2 deflects around the hinge axis, thereby effectively improving the practicability of the device.

[0035] Reference Figure 1-Figure 3 The hinged end of the lock hook 2 and the elevator floor door panel 1 extends to the inside of the storage slide groove 6 and is fixedly connected to the ejection gear 15. One end of the storage slide rod 7 is fixedly connected to the ejection rack 16, and the ejection rack 16 is meshed with the ejection gear 15.

[0036] When in use, when the lock hook 2 is driven to deflect around the hinge axis, the lock hook 2 drives the ejection gear 15 to rotate, and at the same time, the ejection gear 15 engages with the ejection rack 16, and drives the ejection rack 16 to push the storage slide bar 7 to move along the length direction of the storage slide groove 6. At the same time, the storage slide bar 7 pushes the ejection mounting plate 8 along the length direction of the storage slide groove 6 to drive the pressure sensor 9 to form a conflict with the other elevator floor door panel 1, so that the pressure sensor 9 is used to determine whether the two elevator floor door panels 1 are closed, thereby effectively improving the practicality of the device.

[0038] When in use, first, an inductive connection is formed with the elevator car through the wireless sensor 18. When the elevator car moves to a position aligned with the elevator floor door panel 1, induction is formed between the wireless sensor 18 and the car, and the induction signal is transmitted to the digital display controller 17. At this time, the digital display controller 17 receives the induction signals of the air pressure sensor 5 and the pressure sensor 9 to determine whether there is danger, thereby determining whether the elevator floor door panel 1 can be opened. Then, when the digital display controller 17 determines that the elevator floor door panel 1 is in a dangerous state, the digital display controller 17 remotely sends a danger alarm to the terminal device of the staff, and at the same time starts the buzzer alarm 19 to issue a danger alarm to people near the elevator floor door panel 1, thereby effectively improving the safety of the device.

[0042] When in use, a silicone waterproof coating is applied on the surface of the elastic airbag 4, the digital display controller 17, and the wireless sensor 18, so that a waterproof layer is formed on the surface of the elastic airbag 4, the digital display controller 17, and the wireless sensor 18, thereby effectively improving the corrosion resistance of the surface of the elastic airbag 4, the digital display controller 17, and the wireless sensor 18 and extending the service life of the device.

[0043] A method for detecting an elevator door lock fault, the method comprising the following steps: S1: First, drive the elevator floor door panel 1 to close, and drive the lock hook 2 to hook with the lock buckle at one end of another elevator floor door panel 1; S2: When the lock hook 2 is hooked around the hinge shaft and the lock buckle, the eccentric wheel 10 is driven to form a rolling conflict with the contact wheel 14, and the extrusion plate 13 is pushed to squeeze the elastic airbag 4. At this time, the air pressure sensor 5 is used to monitor the air pressure change inside the installation tube 3 in real time, and the air pressure change is compared with the set value to determine whether the lock hook 2 is working normally; S3: At the same time, when the lock hook 2 is hooked with the lock buckle around the hinge shaft, the ejection gear 15 is driven to engage with the ejection rack 16, and the ejection rack 16 drives the storage slide bar 7 to eject the ejection mounting plate 8 along the length direction of the storage slide groove 6, and at the same time, the ejection mounting plate 8 drives the pressure sensor 9 to form a conflict with the other elevator floor door panel 1, so as to use the pressure sensor 9 to determine whether the two elevator floor door panels 1 are closed, and determine whether the elevator floor door panel 1 has a closing failure.

[0044] The implementation principle of the elevator door lock fault detection system and method of the present embodiment is as follows: first, when the elevator floor door panel 1 is driven to close, the elevator floor door panel 1 drives the lock hook 2 to form a fixed connection with the lock buckle at one end of another elevator floor door panel 1, so that the lock hook 2 is deflected around the hinge axis and then reset, so that the lock hook 2 hooks the lock buckle, and at the same time, the lock hook 2 drives the transmission component to push the elastic airbag 4 to move toward the inside of the installation tube 3, thereby reducing the space inside the installation tube 3, and then increasing the air pressure inside the installation tube 3, and at the same time, an air pressure sensor 5 is set to monitor the air pressure change inside the installation tube 3 in real time; Then, when the lock hook 2 fails to hook the lock buckle, resulting in a malfunction in closing the elevator floor door panel 1, the rotation angle of the lock hook 2 around the hinge axis does not reach the set value. At this time, the lock hook 2 drives the eccentric wheel 10 to rotate, and at the same time, the eccentric wheel 10 forms a rolling bottom through the abutting wheel 14 and one end of the extrusion plate 13, and the extrusion plate 13 pushes the guide slide bar 12 to move along the length direction of the guide slide groove 11, and at the same time, one end of the extrusion plate 13 squeezes the elastic airbag 4 into the interior of the installation tube 3, thereby compressing the internal space of the installation tube 3 and increasing the air pressure inside the installation tube 3. At the same time, because the rotation angle of the lock hook 2 around the hinge axis does not reach the set value, the extrusion plate 13 pushes the elastic airbag 4 to retract into the interior of the installation tube 3. The moving distance is shortened, and the air pressure change inside the installation tube 3 does not reach the set value. At the same time, the air pressure change data inside the installation tube 3 is transmitted to the digital display controller 17 in real time through the air pressure sensor 5 for analysis and processing, and then a warning is issued to the staff and people close to the elevator through the buzzer alarm 19; When the elevator floor door panel 1 is driven to drive the lock hook 2 to approach the other elevator floor door panel 1, and the lock hook 2 is deflected around the hinge axis by force and then reset to hook the lock buckle, the lock hook 2 drives the ejection gear 15 to rotate, and the ejection gear 15 is meshed with the ejection rack 16, and drives the ejection rack 16 to push the storage slide bar 7 to move along the length direction of the storage slide groove 6, and at the same time, the storage slide bar 7 drives the ejection mounting plate 8 to pass through the storage slide groove 6 to approach the other elevator floor door panel 1, and at the same time, the ejection mounting plate 8 pushes the pressure sensor 9 to form a conflict with one end of the other elevator floor door panel 1, so that the pressure sensor 9 transmits the pressure signal to the sensing control component. When the storage slide bar 7 pushes the pressure sensor 9 to move toward the other elevator floor door panel 1 along the length direction of the storage slide groove 6, and the pressure sensor 9 does not sense the pressure signal, the sensing control component determines that the two elevator floor door panels 1 are not close to each other, thereby timely issuing a warning to the staff and the people close to the elevator; Then, when it is necessary to test the normal function of the air pressure sensor 5, manually pull the buckle 20 to move upward along the length direction of the guide slide rod 12, and drive the extrusion plate 13 to squeeze the contact wheel 14 and retract it into the interior of the mounting tube 3, then rotate the buckle 20 around the hinge axis to form a hook with the L-shaped buckle head 21, and then loosen the buckle 20 so that the extrusion plate 13 squeezes the elastic airbag 4 to retract into the interior of the mounting tube 3 to a fixed distance, and then wait for the monitoring value of the air pressure sensor 5 to stabilize, and compare it with the preset value, so as to facilitate the rapid detection of the normal monitoring function of the air pressure sensor 5.

At this time, the air pressure sensor (5) is used to monitor the air pressure change inside the installation tube (3) in real time, and the air pressure change is compared with the set value to determine whether the lock hook (2) is working normally; S3: When the lock hook (2) is hooked around the hinge shaft and the lock buckle, the ejection gear (15) is driven to mesh with the ejection rack (16), and the ejection rack (16) drives the storage slide bar (7) to eject the ejection mounting plate (8) along the length direction of the storage slide groove (6), and at the same time, the ejection mounting plate (8) drives the pressure sensor (9) to form a conflict with another elevator floor door panel (1), so as to use the pressure sensor (9) to determine whether the two elevator floor door panels (1) are closed, and determine whether the elevator floor door panel (1) has a closing failure.
