Description

Technical Field

[0001] The invention relates to the field of elevators, and in particular to a landing door system. Background Art

[0002] More and more buildings are using sightseeing elevators, and the requirements for the glass area of ​​the glass landing doors in the landing door system are getting higher and higher. Even frameless fully transparent glass landing doors are required to meet better sightseeing effects. Since ordinary landing doors are equipped with lock core holes to install lock cores to unlock the landing door devices in the landing door system, when frameless fully transparent glass landing doors are used, if a hole is opened on the glass to set the lock core, it will greatly affect the sightseeing effect, because the unlocking method is generally wire rope unlocking or top rod unlocking. If it is set on the glass landing door, it will be completely exposed to the passengers, which is very unsightly. Therefore, general elevator manufacturers set the lock core on the door brow. However, when it is set on the door brow, the biggest problem is that when the height of the landing door is high, it will be extremely inconvenient for maintenance personnel to unlock it, and it may even cause accidents of falling into the shaft.

[0021] like Figure 1 As shown, the landing door system provided in this embodiment includes a glass landing door 7, a landing door device 20, a landing door hanging device 21, a landing door guiding device 6 and a landing door unlocking device 30;

[0022] The floor door hanging device 21 hangs the glass floor door 7 on the floor door device 20, and the floor door device 20 has a door lock device 22 for locking and unlocking the floor door device 20; the door lock device 22 is Figure 1 Not shown in Figure 2 It can be seen from the partially enlarged landing door device 20 that the landing door device 20 is fixedly installed on the upper part of the hoistway wall at the landing door.

[0023] The floor door guide device 6 is installed at the lower part of the glass floor door 7 and is used to guide the glass floor door 7; the floor door guide device 6 includes a first guide member 6a and a second guide member 6b, the first guide member 6a is located at the outer part of the floor door, and the second guide member 6b is located at the middle part of the floor door; the floor door unlocking device 30 is installed at the first guide member 6a.

[0024] In this embodiment, there are exemplarily two glass layer doors 7, and a first guide member 6a and a second guide member 6b are installed at the lower part of each layer door. The layer door unlocking device 30 is exemplarily installed at the first guide member 6a at the lower part of the left glass layer door 7. In addition, the layer door unlocking device 30 can also be installed at the first guide member 6a at the lower part of the right glass layer door 7.

[0025] More specifically, if Figures 3 to 6 As shown, the landing door unlocking device 30 includes a mounting seat 1, a lock core 2, a stop bolt 8, a first nut 12, a second nut 11, a third nut 13 and an unlocking wire 5;

[0026] The lower part of the glass door 7 is provided with a first through hole 7a and a second through hole 7b where the first guide member 6a is installed. The first guide member 6a has a rotation-stopping hole 6a1 and a third through hole 6a2. The mounting seat 1 passes through the first through hole 7a and the rotation-stopping hole 6a1 (such as Figure 7 ), the first guide member 6a is fixed to the back of the lower part of the glass layer door 7 by the first nut 12, the anti-rotation bolt 8 passes through the second through hole 7b and the third through hole 6a2, and the first guide member 6a is further fixed by the second nut 11 to prevent the first guide member 6a from rotating;
