Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and particularly relates to a flexible floor door structure matched with a cage. Background Art

[0002] Construction elevators (hereinafter referred to as elevators) are commonly used in building construction to be responsible for vertical transportation of goods and people between various processes of buildings. The elevator mainly uses a cage (hereinafter referred to as the elevator cargo compartment) to load people and goods, and is driven by an elevator drive mechanism for lifting and lowering. A cage door for people and goods to enter and exit is provided on the elevator cargo compartment, and floor doors are provided on each floor of the building to cooperate with the cage door. Initially, the cage door and the floor door of the construction elevator were independent of each other, and a separate power system was required to be responsible for the lifting and lowering of the cage door and the floor door, wasting a lot of resources, resulting in low production efficiency and poor safety performance. To solve the above problems, a design was made according to the mechanical linkage on the cage door. Through the cooperation of the components on the linkage structure with the linkage block on the floor door, the rise of the cage door is used to drive the rise of the floor door, and the floor door descends by its own weight. However, the existing floor doors matched with the cage have the following deficiencies: the floor door is a single-piece rigid structure. To ensure the height space (the space starting from the floor surface upwards) when opening the door, the door frame needs to be lifted and lowered to at least twice the height of the floor door, resulting in a relatively high height of the door frame, and this linkage method cannot be used for opening in buildings with a floor angle. In addition, there are also examples where the floor door is a two-piece rigid structure. Although this meets the requirement of the height space when opening the door, the structure is relatively complex. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a flexible floor door structure matched with a cage, which uses a wire rope mesh surface to replace the door panel of the floor door, and through the flexible structure, the floor door can be lifted and lowered even when the height of the door frame is relatively low.

[0004] The utility model adopts the following technical solutions:

[0005] A flexible floor door structure matched with a cage includes an upper door frame beam, side tracks, a counterweight linkage group, a lower door frame beam and a wire rope mesh surface. The upper door frame beam, the side tracks and the lower door frame beam are welded to form a door frame body. The counterweight linkage group is connected to the lower end of the wire rope mesh surface. At least part of the wire rope mesh surface and the counterweight linkage group can slide relative to the side tracks. The upper end of the wire rope mesh surface is fixedly connected to the upper door frame beam. The wire rope mesh surface includes stainless steel wire ropes and circular ring connectors. The stainless steel wire ropes are arranged in an arc or inclined shape to form a mesh structure, and the circular ring connectors are connected between adjacent stainless steel wire ropes.

[0006] Preferably, the side track includes a side track main body and a stroke limiting block located within the side track main body, and one side of the counterweight linkage group has a limiting end that matches the stroke limiting block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] For the convenience of understanding the technical solution of the present utility model, the following is a detailed description in combination with the attached drawings and specific embodiments.

[0018] Example 1

[0019] As Figures 1-5 shown, a flexible floor door structure cooperating with a cage includes an upper door frame beam 1, side tracks 2, a counterweight linkage group 3, a lower door frame beam 4, and a wire rope mesh surface 5;

[0020] As Figure 1 shown, the upper door frame beam 1, the side tracks 2, and the lower door frame beam 4 are welded to form a door frame body;

[0021] The counterweight linkage group 3 is connected to the lower end of the wire rope mesh surface 5 and can move along with the movement of the lower end of the wire rope mesh surface 5; the upper end of the wire rope mesh surface 5 is fixedly connected to the upper door frame beam 1, and at least part of the wire rope mesh surface 5 and the counterweight linkage group 3 can slide relative to the side tracks 2. The wire rope mesh surface 5 includes stainless steel wire ropes 6 and ring connectors 7. The stainless steel wire ropes 6 are arranged in an arc or inclined shape to form a mesh structure. The ring connectors 7 are connected between adjacent stainless steel wire ropes 6. The mesh structure formed by connecting the stainless steel wire ropes 6 through the ring connectors 7 has a certain elasticity and can be compressed in the vertical direction.

[0022] As Figure 1 shown, the flexible floor door structure has a first state. In the first state, the limiting end 8 cooperates with the stroke limiting block 11 for limiting, and the wire rope mesh surface 5 and the counterweight linkage group 3 cannot move. The first state is the closed door state.

[0023] As Figure 2 shown, the flexible floor door structure has a second state. In the second state, the limiting end 8 contacts and cooperates with the stroke limiting block 11 for limiting, and the stainless steel wire ropes 6 of the mesh structure are in a compressed state. The second state is the open door state.

[0024] When the door needs to be opened, the driving device on the cage door 15 pops out and contacts the counterweight linkage group 3, and then the cage door opens (rises upward). The driving device on the cage door moves upward, driving the wire rope mesh surface 5 and the counterweight linkage group 3 to move upward, so that the floor door is in the open state. When the floor door is in the open state, the stainless steel wire ropes 6 are in a compressed state. The wire rope mesh surface is composed of flexible stainless steel wire ropes 6 and ring connectors 7 and can be stretched and compressed in the up and down directions.

[0025] When the door needs to be closed, the cage door 15 closes, that is, the driving device 14 on the cage door 15 moves downward. The wire rope mesh surface 5 and the counterweight linkage group 3 are closed synchronously with the cage door under the action of gravity and the elastic force of the stainless steel wire ropes 6. When the cage door is completely closed, the floor door is closed at the same time, and the driving device 14 on the cage door retracts to realize the closing of the floor door.

[0026] Example 2

[0027] As Figures 3-5 shown, the difference between Embodiment 2 and Embodiment 1 is that the side track 2 includes a side track main body 12 and a stroke limit block 11 located inside the side track main body 12. The stroke limit block 11 has a notch. One side of the counterweight linkage group 3 has a limit end 8 that matches the stroke limit block 11. The counterweight linkage group 3 further includes a cage door linkage button 9 and a counterweight main body 10. The cage door linkage button 9 is arranged on the side of the counterweight main body 10 facing the cage door. The limit end 8 is a door closing self-locking button and is located on the end face of the counterweight main body 10.

[0028] When the door needs to be opened, the driving device on the cage door 15 pops out and contacts the cage door linkage button 9 of the counterweight linkage group 3. The cage door linkage button 9 triggers the retraction of the limit end 8, so that the counterweight linkage group 3 can slide upward along the side track 2. Then the cage door opens, and the driving device 14 on the cage door moves upward to drive the wire rope mesh surface 5 and the counterweight linkage group 3 to move upward, so that the floor door is in an open state. When the floor door is in an open state, the wire rope mesh surface 5 is in a compressed state. The wire rope mesh surface is composed of flexible stainless steel wire ropes 6 and circular ring connectors 7 and can be stretched and compressed in the up and down directions.

[0029] When the door needs to be closed, the cage door 15 closes, that is, the driving device 14 on the cage door moves downward, and the wire rope mesh surface 5 and the counterweight linkage group 3 are closed synchronously with the cage door under the action of gravity. When the cage door is completely closed, the floor door closes at the same time. The driving device on the cage door retracts, and the cage door linkage button 9 pops out, causing the limit end 8 to pop out synchronously. The linkage limit end 8 is stuck into the notch of the stroke limit block 11 to realize the self-locking closing of the floor door.

[0030] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is subject to the scope defined by the claims. Several improvements and refinements made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as within the protection scope of the present invention.
