Description

Technical Field

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

[0002] Traditional elevator landing door systems all have a small door cover structure, where the landing door device is fixed to the designed small door cover, which is then fixed to the elevator shaft door wall. The advantage of this solution is that after the elevator door is installed, the small door cover is used as the entrance of the elevator door, because the structural dimensions of the small door cover are pre-designed, ensuring that after the installation, all safety requirements for opening the elevator door are in line with the design, and the gap between the small door cover and the shaft is completed through secondary decoration. This structure has very low requirements on the shaft material form and shaft tolerance, and all problems can be solved through secondary decoration.

[0003] Due to the development of the times and the guidance of national environmental protection requirements such as energy conservation and emission reduction, new prefabricated buildings are becoming more and more popular, such as factory steel structure assembly, which has a short manufacturing cycle, high economy, and pollution-free construction. In the field of elevators, steel hoistways are also becoming more and more popular, especially in the field of villa elevators and home elevators in low-rise buildings. It is becoming more and more common to use steel or aluminum profile elevator hoistways in low-rise buildings. Customers do not need to reserve traditional concrete hoistways in the building. If elevators can be installed in such building structures, it can not only save the installation time of the elevator, but also eliminate the use of small door frames, saving time, labor and cost. Summary of the invention

[0027] Reference Figure 1-4 The elevator of this embodiment includes components of conventional elevators such as a car, a vertical beam, a traction system, and a landing door system. The landing door system in this embodiment includes a bottom support 3, a top support 1, a landing door 5, a switch mechanism 4 located above the landing door 5, a guide mechanism 6 located below the landing door 5, a connector 7 for connecting the switch mechanism 4 to the top support 1, an entrance frame 2, and a column 8. The switch mechanism 4 is used to drive the landing door 5 to open and close. The guide mechanism 6 is fixedly connected to the bottom support 3, and the connector 7 and the switch mechanism 4 are fixedly connected to the top support 1; the entrance frame 2 and the column 8 are both arranged in the vertical direction, and a sealing plate 9 is provided between the entrance frame 2 and the column 8.

[0028] Both ends of the top support member 1 and the bottom support member 3 are fixed on the column 8, the top of the inlet frame 2 is fixed on the bottom surface of the top support member 1, and the bottom of the inlet frame 2 is fixed on the top surface of the bottom support member 3. The sealing plate 9 is arranged in the gap formed after assembly. The sealing plate 9 is made of glass, PVC, stainless steel or aluminum profile.

[0029] The column 8, the top support member 1 and the bottom support member 3 are part of the building structure itself. By converting part of the building structure itself into the bottom support member 3, the top support member 1 and the column 8, the installation and use of the floor station door system are more convenient, and the door frame structure in the existing elevator can be eliminated, further saving costs.

[0030] The top support member 1 is provided with a first through slot 101 and a second through slot 102, and the first through slot 101 and the second through slot 102 are provided along the opening and closing direction of the landing door 5. The horizontal height of the first through slot 101 is higher than the horizontal height of the second through slot 102. The first through slot 101 is used to install the connector 7, and the second through slot 102 is used to install the switch mechanism 4. The switch mechanism 4 and the connector 7 are also fixedly connected to increase the strength. The through slot on the top support member 1 is used to fix the switch mechanism 4, and the through slot on the bottom support member 3 is used to fix the guide mechanism 6. The through slots are both provided along the opening and closing direction, and the fixing points can be adjusted according to the actual width and installation requirements.

[0031] like Figure 3-4As shown, there is at least one through slot on the bottom support member 3 for installing the guide mechanism 6. In some embodiments, through slots are provided on the upper surface and the bottom surface of the bottom support member 3 close to the guide mechanism 6 to further enhance the stability of the guide mechanism 6.

[0032] like Figure 3-4 As shown, the connecting member 7 in this embodiment includes a vertical portion fixedly connected to the top support member 1 and a bent portion fixedly connected to the switch mechanism 4. When installed, the vertical portion is in contact with one side of the top support member 1; the guide mechanism 6 is connected to the bottom support member 3 through an L-shaped connecting member, one side of the L-shaped connecting member is in contact with one side of the bottom support member 3, and the guide mechanism 6 is respectively in contact with the top support member 1 and the bottom support member 3 through the upper and lower connecting members to control the distance between the landing door 5 and the entrance frame 2.

[0033] like Figure 1 and 3 As shown, the top support member 1 in this embodiment includes a first beam 111 and a second beam 112, a first through slot 101 is provided on a surface of the first beam 111 close to the connecting member 7, and a second through slot 102 is provided on the top surface of the second beam 112. The top support member 1 is composed of two separate first beams 111 and second beams 112, and a sealing plate 9 made of the same material as the above is provided between the first beam 111 and the second beam 112. The bending portion of the upper connecting member 7 is located in the gap between the first beam 111 and the second beam 112, and the bending direction of the bending portion is toward the switch mechanism 4.

[0034] like Figure 4 As shown, in some other embodiments, the top support member 1 is integrally provided, and the first through slot 101 and the second through slot 102 are provided on one side of the integrally provided top support member 1 close to the connecting member 7. The bending direction of the bending portion of the upper connecting member 7 is toward the top support member 1.

[0035] like Figure 1 , 3 -4, the through groove also includes a third through groove opened at the lower part of the top support member 1 near the landing door 5, and the third through groove is used to further fix the switch mechanism 4.

[0036] like Figure 3 and 4 As shown, the guide mechanism 6 in this embodiment includes a sill fixed on the bottom support member 3 and a slider fixed on the landing door 5. The sill is provided with a slide groove, and the slider is accommodated in the slide groove. The bottom of the landing door 5 is provided with a notch on the side away from the entrance frame 2, and the top of the slider is fixed in the notch through a connecting block, which can strengthen the connection strength between the landing door 5 and the sill and further reduce the occupied space of the landing door system.

[0037] The distance between the landing door 5 and the entrance frame 2 is ≤6mm ( Figure 2-4 In the prior art, a small door pocket or secondary decoration is used to control the gap. By adopting the above structure of the present invention, the distance between the landing door 5 and the entrance frame 2 can also be ≤6mm without using a small door pocket.

[0038] like Figure 1-4 As shown, the distance between the two entrance frames 2 is M, which is the elevator door opening width, and the distance between the bottom surface of the top support member 1 and the top surface of the sill is N, which is the elevator door opening height.

[0039] This application uses the good flatness and straightness of the frame shaft itself to cancel the small door cover structure of the elevator floor door and change it to a door cover-free structure. The design has support parts that can be installed and connected, and the positions of the through grooves and columns are arranged. The switch mechanism and the floor station door are connected to the top support parts through the connecting parts to ensure that the distance between the floor station door and the entrance frame is kept within the standard requirements when opening and closing the door, which meets the safety design.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] 1. The small door frame structure has been cancelled, reducing the manufacturer's product cost. Each elevator can save several sets of small door frames according to the floor station, which has better economy.

[0042] 2. The width of the frame door opening is the same as the door opening width, which saves the cost of secondary decoration of the door opening and the small door frame when there is a small door frame.

[0043] 3. The structure without door frame looks simple and beautiful. Passengers only see the frame and elevator door. The traditional secondary decoration structure with door frame may have different surface materials of secondary decoration, frame materials and small door frame materials, which leads to visual confusion and poor aesthetics.

[0044] 4. The arrangement of small door frames occupies a certain depth of the elevator shaft, wasting shaft space. Using no door frames can leave space for the car and provide better riding comfort. Especially in villas with relatively compact space, it is particularly important to save useless space and expand effective space.

[0045] 5. The columns, top supports and bottom supports are part of the building structure itself. By converting part of the building structure itself into the bottom supports and top supports, the installation and use of the landing door system are more convenient.

[0046] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
