[0034] Embodiment 1.

[0035] In one embodiment of the present invention, Figures 1-2 As shown, a floor door linkage device is provided, including a cage (not shown), a floor door frame 10, a floor door 20, an electromagnetic lock 30, a mechanical lock 40, a signal verification switch and a locking verification switch 60.

[0036] The cage is arranged in the hoistway, and the landing door frame 10 is arranged at a position of the floor plate 90 corresponding to the hoistway.

[0037] The floor door 20 is disposed on the floor door frame 10 and is locked by the mechanical lock 40 .

[0038] The signal verification switch is arranged on the cage and / or the floor door 20 .

[0039] The electromagnetic lock 30 is disposed on the floor door frame 10 and is used to lock the floor door 20 . The locked floor door 20 can be opened after the signal verification switch transmits an electrical signal.

[0040] The locking verification switch 60 is arranged on the floor door frame 10 and / or the floor door 20, and is linked with the cage door 100 of the cage and the electromagnetic lock 30. Specifically, the locking verification switch 60 is linked with the door machine 120 of the cage door 100.

[0041] When the cage door 100 is opened, the electromagnetic lock 40 is opened, the locking verification switch 60 is disconnected, and the floor door 20 can be opened; when the floor door 20 is closed, the locking verification switch 60 is started, the cage door 100 can be closed, and the electromagnetic lock 30 locks the floor door 20 again.

[0042] The working process of the floor door linkage device of the embodiment of the utility model is as follows: after the cage of the construction elevator is lifted to the level floor, the cage door 100 opens automatically. When the cage door 100 opens to a specified width, the signal verification switch arranged on the cage and / or the floor door 20 obtains a signal that the cage door 100 opens to a specified width, and outputs the signal to the electromagnetic lock 30 arranged on the floor door frame 10. The electromagnetic lock 30 opens automatically, and the electromagnetic lock 30 releases the lock on the floor door 20. The construction personnel manually turns the mechanical lock 40 on the floor door 20, opens the mechanical lock 40 and opens the floor door 20 at the same time. After the floor door 20 is opened, the locking verification switch 60 is disconnected, and the cage door 100 is controlled to always remain in an open state. When the construction personnel manually close the floor door 20, the mechanical lock 40 is locked, and the locking verification switch 60 is actuated. At this time, the cage door 100 will automatically close with a delay. When the cage door 100 closes to a specified width, the electromagnetic lock 30 of the floor door 20 is actuated to lock the floor door 20. In this way, the construction elevator can only operate after the floor door 20 and the cage door 100 are completely closed. If one of the floor door 20 or the cage door 100 is not completely closed and locked, the construction elevator cannot operate, ensuring safe and reliable production.

[0043] Further, the signal verification switch is a magnetic induction switch 50, and a magnetic stripe 110 (not shown) is provided on the cage door 100. The magnetic induction switch 50 is provided on the floor door 20 to sense the magnetic stripe 110 and transmit the sensing signal to the electromagnetic lock 30. Specifically, as the cage rises or falls, the magnetic stripe 110 provided on the cage door 100 will reach a certain height, and then the magnetic induction switch 50 on the floor door 20 can sense the magnetic stripe 110 to send a signal.

[0044] In this embodiment, an anti-pinch device (not shown) is provided on the cage door 100. The anti-pinch device can prevent people or objects from being pinched during the process of entering and exiting the cage, thereby improving the safety of use.

[0045] The floor door 20 is provided with a door handle 80 for opening the mechanical lock 40. The door handle 80 is used to operate the opening or closing of the mechanical arm.

[0046] More specifically, the floor door 20 includes a left door leaf and a right door leaf, and the left door leaf and the right door leaf are doors defined by relative positions. When one side is defined as the left door leaf, the other side is the right door leaf. The left door leaf and the right door leaf are respectively arranged on the left and right sides of the floor door frame 10, and are locked by the mechanical lock 40.

[0047] The signal verification switch is arranged on at least one of the cage, the left door leaf and the right door leaf.

[0048] The electromagnetic lock 30 is disposed on the floor door frame 10 and is used to lock the left door leaf and the right door leaf. The locked left door leaf or the right door leaf can be opened after the signal verification switch transmits an electrical signal.

[0049] The locking verification switch 60 is arranged on the left door leaf and the floor door frame 10 at a position corresponding to the right door leaf, and is linked with the cage door 100 and the electromagnetic lock 30 .

[0050] When the cage door 100 is opened, the electromagnetic lock 40 is opened, the locking verification switch 60 is disconnected, and the left door leaf and the right door leaf can be opened; when the left door leaf and the right door leaf are closed, the locking verification switch 60 is activated, the cage door 100 can be closed, and the electromagnetic lock 30 locks the left door leaf or the right door leaf again.

[0051] Furthermore, one of the left door leaf and the right door leaf is provided with a door stopper so as to close the other door leaf when one of the door leaves is closed.

[0052] Embodiment 2.

[0053] The difference between this embodiment and the above-mentioned embodiment 1 is that the signal verification switch is an automatic reset travel switch, and the automatic reset travel switch is arranged on the door machine 120 of the cage. After the cage door 100 touches the automatic reset travel switch, the automatic reset travel switch transmits the touch signal to the electromagnetic lock 30.

[0054] Embodiment three.

[0055] The present embodiment provides an intelligent hoisting machine for construction in a shaft, which includes the floor door linkage device of the above-mentioned embodiment 1 or embodiment 2. The intelligent hoisting machine for construction in a shaft of the present embodiment uses the above-mentioned floor door linkage device, and can also ensure that the construction hoist can only operate after the floor door 20 and the cage door 100 are completely closed. If one of the floor door 20 or the cage door 100 is not completely closed and locked, the construction hoist cannot operate, thereby ensuring safe and reliable production.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
