Further, one end of the long plate of L-shaped plate is fixedly installed with a door lock switch fixed support 12, the door lock switch fixed support 12 is fixedly installed with a door lock electrical switch 13, and the door lock electrical switch 13 is used for detecting whether the door leaf is in the locking state.

[0041] As shown in Figure 3 Door lock locking assembly 17 includes door lock fixing piece 3 and door lock piece 5, and the door lock fixing piece 3 is a three-dimensional structure with three mutually perpendicular surfaces, and the three surfaces of the three-dimensional structure are bottom panel, front panel and side panel respectively, wherein the bottom panel is fixedly installed on the top of the door leaf, and preferably, the bottom panel is fixedly connected with the top of the door leaf 18 through the door leaf lifting reinforcing plate 4 to enhance the stability of the connection between the two; asFigure 5 As shown, the front panel of the door lock fixing member 3 has a side U-shaped opening, and the door lock fastener 5 is rotatably installed inside the door lock fixing member 3 and directly opposite the side U-shaped opening.

[0042] like Figure 4 As shown, the door lock fastener 5 is perpendicularly arranged to the door lock mounting plate 11. The door lock fastener 5 includes a pivot and a switch plate. The pivot is perpendicular to the door lock fixing member 3. The switch plate is rotatably connected to the door lock fixing member 3 through the pivot. A door lock contact plate bracket 6 is fixedly installed inside the switch plate. A door lock switch contact plate 7 is provided on the door lock contact plate bracket 6. The front end of the switch plate is provided with a protrusion 21 that bends inward (i.e., towards the U-shaped opening side of the door lock fixing member). The protrusion 21 is connected to the inner side panel of the door lock fixing member 3 through a compression spring 2. When the sides are connected, the compression spring 2 is in a static state, neither compressed nor stretched. The rear end of the switch plate is provided with a short baffle 22 that bends outward (i.e., in the opposite direction to the U-shaped opening side of the door lock fixing member). The short baffle 22 is directly above the blocking member 23 of the door lock hanging plate 11. The short baffle 22 abuts against the blocking member 23, thereby realizing the door lock. In addition, the door lock switch contact plate 7 is in contact with the door lock electrical switch 13. At this time, the door lock electrical switch 13 is in a closed state, indicating that the current state is the door lock.

[0043] With the above settings, the vertical elevator can be locked when it is not started. That is, the blocking member 23 on the inner side of the door lock mounting plate 11 and the short baffle 22 at the rear end of the switch plate cooperate with each other. The blocking member 23 can abut against the short baffle 22 to prevent the door locking member 5 from moving upward. Furthermore, since the door lock mounting plate assembly is installed on the door frame and the door lock locking assembly is installed on the door leaf, the position between the door leaf and the door frame can be fixed, and the automatic door leaf of the elevator can be locked. At this time, the door lock switch contact plate 7 is in contact with the door lock electrical switch 13, the door lock electrical switch 13 is in the closed state, and the door leaf is detected to be in the locked state.

[0044] Furthermore, the two ends of the compression spring 2 are respectively fixed to the inner side of the side panel and the outer side of the protrusion. To ensure that the position of the door locking component is fixed when the compression spring contracts and returns to its original position, this utility model also provides a compression spring guide screw 1, which passes through the interior of the compression spring 2. Preferably, as follows... Figure 4 As shown, a screw is used as the spring guide screw 1.

The anti-loosening nut can be used to limit the spring and adjust the pressure.

[0045] likeFigure 5 As shown, in the door lock device proposed in this utility model, the door lock locking assembly 17 further includes a door lock connecting rod 8 and a door lock connecting rod fixing member 9. The door lock connecting rod fixing member 9 is an N-shaped plate, which is fixedly installed at the bottom of the door panel. The door lock connecting rod 8 rotates coaxially with the rotating shaft of the door lock fastening member 5. Specifically, the upper end of the door lock connecting rod 8 is fixedly connected to the rotating shaft in the door lock fastening member 5 (e.g., by welding), and the lower end passes through the door lock connecting rod fixing member 9. The tail of the door lock connecting rod 8 is fixed with a locking member 10 using a set screw (or screw). The vertical position and left and right rotation angle of the locking member 10 are adjustable. Figure 7 As shown, in the locked state, the locking member 10 protrudes from the door lock connecting rod fixing member 9, as... Figure 8 As shown, this can prevent the upper door from opening upwards, thus locking the lower door. When the door locking component 5 rotates to unlock the upper door, the door lock connecting rod 8 rotates coaxially, causing the locking component 10 at its tail to rotate into the door lock connecting rod fixing component 9. At this time, the lower door can be unlocked and opened upwards. Through the above settings, the mechanical locking device of the lower door moves synchronously with the door lock locking component 17, thereby achieving the locking of multiple doors.

[0046] like Figure 2 As shown, the door lock mounting plate assembly also includes an emergency unlocking assembly, which includes an emergency unlocking rod 16 and an emergency unlocking pull rope 15. One end of the emergency unlocking rod is rotatably mounted on the outside of the fixed plate, and the other end is connected to the emergency unlocking pull rope 15. The other end of the emergency unlocking pull rope 15 is connected to a rotating component, which is mounted on a triangular lock 14 and rotates synchronously with the lock cylinder inside the triangular lock 14. The triangular lock 14 is mounted on the door frame, and its lock hole is located on the surface of the door frame. In case of an emergency, the triangular lock 14 on the elevator door frame can be manually opened using the emergency unlocking key. During the opening process, the internal lock cylinder of the triangular lock 14 is rotated, thereby pulling the emergency unlocking rope 15 and the emergency unlocking lever. Since the emergency unlocking lever is located on the outside of the fixed plate, during the pulling process, the emergency unlocking rope 15 contacts the door locking member 5 and drives the door locking member 5 to rotate to the right. The front end of the door locking member 5 horizontally presses the compression spring 2 to the left to retract. At this time, the short baffle at the rear end of the switch plate separates from the blocking member in the door lock hanging plate 11, the door lock switch contact plate 7 separates from the door lock electrical switch 13, the door lock electrical switch 13 is disconnected, and an opening and unlocking signal is generated. At this time, the door lock device can be manually unlocked, and the elevator automatic door can move upward and open.

[0047] The specific working process of this utility model is as follows:

[0048] Electric door knife devices in existing vertical elevator automatic door systems, such as Figure 8As shown, the up and down movement of the door blade 24 is controlled by the door blade opening and closing limit switch 25 installed on the door blade sliding platform. When the door blade rotates counterclockwise to the unlocking state, the door blade is in a vertical state with the door leaf. At this time, the door blade limit switch on the fixed sliding platform acts to drive the door blade to move upward. In this process, as shown in Figure 6 As shown, the door blade 24 rotates and enters the side U-shaped opening of the front panel of the door lock fixing part 3, and the front end protruding part 21 of the rear switch plate of the side U-shaped opening is in contact with the door blade during the rotation, and moves to the inside of the side U-shaped opening (i.e. moves horizontally to the left) with the rotation, the compression spring 2 is squeezed to contract, the compression spring guide screw 1 inside the compression spring 2 further protrudes, and during the rotation, the rear end short stop plate 22 of the switch plate is separated from the blocking part 23 inside the door lock hanging plate 11, the door lock switch contact plate 7 is separated from the door lock electrical switch 13, the door lock electrical switch 13 is disconnected, the door leaf is detected to be in an unlocked state (i.e. in a non-locking state), and the door is opened and unlocked. Since the door lock electrical switch is connected to the control system of the elevator, the signal detected by the door lock electrical switch is input into the control system of the elevator. At this time, the elevator can normally run up and down.

[0049] Further, with the upward movement of the door blade that penetrates into the side U-shaped opening, the door lock locking assembly 17 and the door leaf fixed below it are driven upward to achieve the unlocking and opening of the vertical elevator door leaf.

[0050] At the same time, as shown in Figure 7 When the door lock connecting rod 8 rotates coaxially with the door lock fixing part 5, the locking part 10 at the tail of the door lock connecting rod 8 rotates into the door lock connecting rod 8 fixing part, at this time, the lower door leaf can be unlocked and opened upward.

[0051] When the door is closed, the door lock locking assembly 17 falls with the door leaf. When the door leaf falls to the closed position under the action of gravity, the door blade rotates back to the original position, at this time, the compression spring 2 resets to make the door lock fixing part 5 rotate to the right to keep a 90° vertical locking state with the door lock hanging plate 11, i.e. the rear end short stop plate 22 of the switch plate interacts with the blocking part 23 in the door lock hanging plate 11 again, at this time, the door lock electrical switch 13 contacts with the door lock switch contact plate 7, the door lock electrical switch 13 is in a closed state, the door leaf is detected to be in a locking state, at this time, the elevator control system controls the elevator to stop running. At the same time, the door lock connecting rod 8 rotates coaxially with the door lock fixing part 5, the locking part 10 at the tail of the door lock connecting rod 8 rotates back to the original position, at this position, the locking part 10 can block the upward opening of the next door leaf, i.e. the locking of the next door leaf is achieved.

[0052] Further, when an unexpected situation causes the electrical switch to fail, the emergency unlocking key is used to manually open the triangular lock 14 on the elevator door frame, and during the opening process, the triangular lock 14 inside the lock core is rotated, and then the emergency unlocking pull rope 15 and the emergency unlocking rod are pulled. During the pulling process, the emergency unlocking pull rope 15 contacts the door lock fastener 5 and drives the door lock fastener 5 to rotate to the right, and the front end of the door lock fastener 5 horizontally presses the compression spring 2 to the left to contract. At this time, the short baffle at the rear end of the switch plate is separated from the blocking piece in the door lock hanging plate 11, the door lock switch contact plate 7 is separated from the door lock electrical switch 13, the door lock electrical switch 13 is disconnected, and an unlocking signal is generated. At this time, the manual unlocking of the door lock device can be realized, and the elevator automatic door can be moved upward to open.

[0053] The door lock device of the vertical elevator automatic door system provided by the utility model adopts a horizontal sliding type, gravity locking, and spring auxiliary locking mode, realizes mechanical locking of the vertical elevator automatic door, has compact structure, stable operation, few transmission parts, convenient maintenance, and compared with the traditional elevator door lock device, effectively reduces the use amount of switches, and has low installation precision requirement; in addition, the door lock electrical switch is additionally installed for detecting door leaf closing verification, and the door lock electrical switch can be used for AC / DC circuit control, so as to be connected with the vertical elevator automatic door system; the mechanical locking mode is adopted, simultaneous locking of multiple doors is realized, the reliability of the electrical switch operation is ensured, and the mechanical locking can also avoid the damage of other parts caused by the failure of the electrical switch due to unexpected situations.

[0054] Although the specific embodiments of the utility model are described above with reference to the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or deformations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
