[0002] The known intelligent elevator folding door falls naturally into place by its own weight, and cannot realize mechanical locking and electrical control. Each floor of the construction site is equipped with a landing door. When the construction elevator cage runs to the floor, the landing door is driven by the mechanism on the elevator cage door to open upwards. When the cage door is closed, the landing door falls by its own weight to close. This solution cannot realize the mechanical interlocking of the landing door and the cage door. The landing door is blocked from falling by its own weight or opened manually, which will cause the landing door to fail, endangering construction safety. Utility Model Content

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] The following describes the electromechanical interlocking mechanism of the folding door of an intelligent elevator according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0024] like Figure 1-6As shown, the electromechanical interlocking mechanism of the folding door of the intelligent elevator in the embodiment of the utility model includes a door frame 1, a folding door 2, an electromagnetic lock 3, a floor call device 4, an electromagnetic lock bayonet 5 and a lifting block 6, a strong magnetic contact 7, a passive magnetic induction proximity switch 8 and an electromagnetic lock control module 70.

[0025] Among them, the folding floor door 2 is movably arranged in the floor door frame 1, the electromagnetic lock 3 and the passive magnetic induction proximity switch 8 are arranged side by side on the floor door frame 1, the electromagnetic lock bayonet 5 and the strong magnetic contact 7 are correspondingly arranged on the folding floor door 2, the floor caller 4 is installed on the floor door frame 1, and the floor caller 4 and the electromagnetic lock 3 and the passive magnetic induction proximity switch 8 are electrically connected.

[0026] It should be noted that the electromagnetic lock 3 and the passive magnetic induction proximity switch 8 are installed side by side on the door frame 1 of the landing door, the electromagnetic lock bayonet 5 and the strong magnetic contact 7 are correspondingly installed on the folding landing door 2, and the electrical control signal is fed back through the electromagnetic lock 3 and the passive magnetic induction proximity switch 8 and the floor caller 4. The electromagnetic lock 3 and the passive magnetic induction proximity switch 8 are electrically connected to the floor caller 4 of each floor, so as to ensure that the electromagnetic lock 3 is opened when the cage is leveled, and the electromagnetic lock 3 is locked after the landing door falls into place when the cage door is closed, and the cage can move up and down at this time.

[0027] The electromagnetic lock bayonet 5 is arranged on the door frame 1 of the landing door, and the electromagnetic lock 3 is engaged with the electromagnetic lock bayonet 5 , the lifting block 6 is arranged on the folding landing door 2 , and the electromagnetic lock control module 70 is electrically connected with the electromagnetic lock 3 .

[0028] It should be noted that after the cage runs to the level position of the floor door frame 1, the electromagnetic lock pin shrinks and is pulled out of the electromagnetic lock bayonet 5 described in this embodiment. At this time, the cage mechanical lock and the lifting block 6 cooperate to drive the folding floor door 2 to open.

[0029] Specifically, the electromechanical interlocking of the floor door is realized, the power is turned on, and the electromagnetic lock 3 is connected to the floor caller 4. When the floor caller 4 receives the signal that the cage is about to stop, it is transmitted to the electromagnetic lock 3. The electromagnetic lock 3 receives the signal and the cage automatically runs to the floor. After the cage is leveled, the passive magnetic induction proximity switch 8 gives a signal and the electromagnetic lock pin 5 contracts. The mechanism (fork) on the cage door drags the lifting block 6 to open the floor door, thereby realizing the electromechanical interlocking between the cage and the floor door. When the cage door falls and closes, the floor caller 4 needs to send a call signal. The folding floor door 2 falls by its own weight as the fork descends. When the cage door is completely closed, the folding floor door 2 also falls into place. At this time, the electromagnetic lock 3 is locked, and the cage executes other call signal instructions to leave the floor. If the folding floor door 2 is not closed in place, the passive magnetic induction proximity switch 8 does not give a signal, and the electromagnetic lock 3 cannot be locked, and the cage cannot execute other call instructions.

[0030] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the electromagnetic lock control module 70 includes a frequency converter 701, a limit switch 702, a floor call module 703, a limit module 704, a resistor box 705, an encoder 706, an elevator drive module 707, a material door drive module 708, a grating control module 709 and a sensor module 7010.

[0031] Among them, the frequency conversion machine 701 is electrically connected to the electromagnetic lock 3 and the passive magnetic induction proximity switch 8, the frequency conversion machine 701 is electrically connected to the limit switch 702, and the frequency conversion machine 701 is electrically connected to the floor call module 703. The frequency conversion machine 701 is electrically connected to the limit module 704, the frequency conversion machine 701 is electrically connected to the resistor box 705, and the frequency conversion machine 701 is electrically connected to the encoder 706. The frequency conversion machine 701 is electrically connected to the elevator drive module 707, the frequency conversion machine 701 is electrically connected to the material door drive module 708, the frequency conversion machine 701 is electrically connected to the grating control module 709, and the frequency conversion machine 701 is electrically connected to the sensor module 7010.

[0032] It should be noted that the floor call module 703 includes an external call box corresponding to the floor call device 4 on each floor, and each external call box controls the electromechanical interlocking of the left door and the right door respectively. The limit module 704 includes the door opening limit switch and the door closing limit switch of the feed door, the door opening limit switch and the door closing limit switch of the discharge door, and includes the upper limit switch and the lower limit switch, the deceleration limit switch, the anti-top limit switch and the skylight limit switch. The material door drive module 708 includes the feed door motor and the discharge door motor, and the feed door and the discharge door are driven to open and close through the material door drive module 708. The grating control module 709 includes the feed door grating and the discharge door grating. The sensor module 7010 includes the sensor pin shaft 1 and the sensor pin shaft 2.

[0033] In one embodiment of the present invention, Figure 1 As shown, the electromagnetic lock 3 and the floor caller 4 are electrically connected to the same power supply.

[0034] It should be noted that the electromagnetic lock 3, the passive magnetic induction proximity switch 8 and the floor caller 4 are electrically connected to the same power supply. The electromagnetic lock 3 and the passive magnetic induction proximity switch 8 are connected to the floor caller 4. When the floor caller 4 receives the signal that the cage is about to stop, it passes it to the electromagnetic lock 3. The electromagnetic lock 3 receives the signal and the cage automatically runs to that floor.

[0035] In one embodiment of the present invention, Figure 1As shown, there are multiple groups of electromagnetic locks 3 and passive magnetic induction proximity switches 8, which are respectively arranged on the door frames 1 corresponding to each floor, and are connected in series.

[0036] It should be noted that an electromagnetic lock 3 and a passive magnetic induction proximity switch 8 are respectively provided on the folding door 2 of each floor, and the electromagnetic lock 3 and the passive magnetic induction proximity switch 8 are electrically connected to the floor call device 4, so that the lifting of the cage and the opening and closing of the floor door are controlled by the frequency conversion integrated machine 701.

[0037] In one embodiment of the present invention, Figure 6 As shown, the electromagnetic lock control module 70 also includes an alarm module, and the alarm module is electrically connected to the frequency conversion integrated machine 701.

[0038] It should be noted that during operation, if the electromagnetic lock 3 is opened manually or the folding door 2 is forcibly opened, the electrical system will alarm and control the cage to stop running immediately.

[0039] The control steps of the electromechanical interlocking device for the floor door of the utility model intelligent construction elevator are as follows: realize the electromechanical interlocking of the floor door, turn on the power, connect the electromagnetic lock 3 and the passive magnetic induction proximity switch 8 to the floor caller 4, and when the floor caller 4 receives the signal that the cage is about to stop, it is transmitted to the electromagnetic lock 3. The electromagnetic lock 3 receives the signal and the cage automatically runs to the floor. After the cage is leveled, the electromagnetic lock pin shrinks, and the cage door mechanism (shift fork) drags the lifting block 6 to open the floor door, thereby realizing the electromechanical interlocking between the cage and the floor door. When the cage door falls and closes, the floor caller 4 needs to send a call signal. The folding floor door 2 falls by its own weight as the shift fork descends. When the cage door is completely closed, the folding floor door 2 also falls into place. At this time, the electromagnetic lock 3 is locked, and the cage executes other call signal instructions to leave the floor. If the folding floor door 2 is not closed in place, the electromagnetic lock 3 cannot be locked, and the cage cannot execute other call instructions. If the folding door 2 is not closed properly, the electromagnetic lock 3 cannot be locked, and the cage cannot execute other call instructions; during operation, if the electromagnetic lock 3 is opened manually or the folding door 2 is forcibly opened, the electrical system will alarm and control the cage to stop running immediately.

[0040] In summary, the electromechanical interlocking mechanism of the intelligent elevator folding floor door of the utility model embodiment realizes the electromechanical interlocking of the floor door, simplifies the manufacturing and installation process, saves costs, improves the safety protection level, and achieves a unified effect, so that different models can be interchangeable. The design meets the technical and safety requirements of construction elevators related to intelligent construction elevators and construction elevators for both people and goods.
