[0037] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0038] The following description, with reference to the accompanying drawings, describes the door device and mechanical linkage system according to the present invention.

[0039] like Figure 1 As shown, in this embodiment, a landing door device is proposed, which includes a door frame 1, a landing door 2, a door lock assembly 3, and a limiting member 4. The landing door 2 is installed on the door frame 1 and can open and close relative to the door frame 1. The door lock assembly 3 includes a bolt 32 and a connecting plate 31 installed on the inner and outer sides of the landing door 2 along the thickness direction of the landing door 2. The bolt 32 is slidably installed on the side of the connecting plate 31 opposite to the landing door 2, and the two bolts 32 can slide synchronously along the connecting plate 31 to unlock or lock the landing door 2. In this embodiment, by adopting the technical solution of two synchronously sliding bolts 32, the landing door 2 can be unlocked or locked on both the inner and outer sides, solving the problem in the prior art that the landing door 2 cannot be conveniently opened and closed from the inside, effectively improving the convenience of opening or closing the landing door 2, and ensuring construction safety. Furthermore, the landing door device also includes a limiting member 4 disposed on the connecting plate 31. A limiting groove 321 is formed on the side of the bolt 32 facing the limiting member 4. When the landing door 2 is unlocked, the limiting member 4 and the limiting groove 321 separate, and the limiting member 4 does not affect the sliding adjustment of the bolt 32 relative to the connecting plate 31. When the landing door 2 is locked, the limiting member 4 is inserted into the limiting groove 321 to lock the bolt 32, preventing the bolt from sliding axially and improving the locking stability of the landing door device.

[0040] like Figure 1 and Figure 2As shown, in the embodiment, the layer door device further comprises a limit switch 5 and a control unit, the control unit is electrically connected with the limit piece 4 and the limit switch 5, the limit switch 5 is used for sending a sensing signal according to the sliding position of the door bolt 32, and the control unit is used for controlling the limit piece 4 to lock the door bolt 32 when the door bolt 32 slides to the position. Specifically, when it is needed to lock the layer door 2, the door bolt 32 needs to be driven to move by an external force first, so that the door bolt 32 slides to the left relative to the connecting plate 31 and continuously approaches the limit switch 5 until the door bolt 32 abuts on the limit switch 5, at this time, the limit switch 5 will send a sensing signal to the control unit, and after the control unit receives the sensing signal, it is confirmed that the door bolt 32 has reached the specified position, then the limit piece 4 can be inserted into the limit slot 321 to avoid the axial sliding of the door bolt 32. At this time, the layer door 2 is locked, the cage can normally operate, and the safety of the cage operation can be effectively ensured, the safety hidden danger is eliminated, and the safety accident is avoided.

[0041] In the embodiment, the layer door device further comprises a position detection unit electrically connected with the control unit, the position detection unit is used for obtaining cage position information and sending a position signal, and the control unit is used for controlling the limit piece 4 to unlock the door bolt 32 when the cage is in position, so that the layer door 2 is opened. The position detection unit continuously monitors the relative position between the cage and the layer door 2, when the cage rises or falls to the position corresponding to the layer door 2, the position detection unit can send a position signal to the control unit, and after the control unit receives the position signal, it is determined that the cage and the layer door 2 have corresponded, at this time, the limit piece 4 can be pulled out of the limit slot 321 to avoid affecting the unlocking of the door bolt 32. In the embodiment, the limit piece 4 is an electromagnet, which is sensitive and has good locking effect. Of course, other structures can also be set according to actual needs, which can cooperate with the limit slot 321 to realize the limiting locking of the door bolt 32.

[0042] As shown in Figure 1 and Figure 4 In the embodiment, a limit hole 311 is formed in the connecting plate 31, the limit hole 311 is a strip hole and extends along the length direction and is used for inserting the door bolt 32. The side of the door bolt 32 facing the connecting plate 31 is in sliding fit with the limit hole 311, and the end of the left side of the connecting plate 31 is provided with a first guide sleeve 312 for the door bolt 32 to pass through, and the first guide sleeve 312 is welded on the connecting plate 31 and forms a guide hole for the door bolt 32 to insert through. The first guide sleeve 312 can guide the sliding of the door bolt 32 and effectively limit the radial deviation of the door bolt 32, thereby improving the stability of the locking of the layer door 2. Figure 4 The horizontal direction is the left-right direction in

[0043] As shown in Figure 1 and Figure 4As shown, in the first embodiment, there are two landing doors 2 arranged opposite each other. The opposite sides of the two landing doors 2 are pivotally connected to the door frame 1. The door lock assembly 3 also includes two positioning plates 33 installed on both sides of the landing doors 2 in the thickness direction. The connecting plate 31 and the positioning plate 33 are respectively installed on the two landing doors 2 and are located on the side of the two landing doors 2 that are close to each other. Under the drive of the staff, the door bolt 32 can slide along the connecting plate 31 toward the positioning plate 33, that is, slide and adjust in the left and right direction to lock or unlock the positioning plate 33 and the connecting plate 31. This embodiment is an implementation method in the case where there are two landing doors 2.

In the unlocked state, the bolt 32 will separate from the second guide sleeve 331. At this time, the bolt 32 can still be inserted into the first guide sleeve 312, as long as it does not affect the swing opening or closing of the landing door 2 relative to the door frame 1. The second guide sleeve 331 also has a guide hole for the bolt 32 to be inserted.
