As shown in fig. 1 and 2, the vertical elevator 100 of an embodiment of the present invention includes an elevator door 10 and a sill 30, the sill 30 is a long strip structure extending along a first direction, a groove extending along the first direction is disposed on the sill 30, and a width direction of the groove is a second direction perpendicular to the first direction. The bottom of the elevator door 10 is mounted with a holding device engaged with the groove of the sill 30 to smoothly move the elevator door 10 in the first direction along the sill 30.

Specifically, in the present application, the vertical elevator 100 includes two elevator doors 10 having the same shape, and the two elevator doors 10 move toward each other in a first direction until they are in a fully closed state, or move in a reverse direction in the first direction until they are in a fully opened state.

In order to clean the groove on the sill 30, the vertical elevator 100 further includes a cleaning device 50, the cleaning device 50 includes a receiving unit 52 and a dust collecting unit 54, the dust collecting unit 54 is used for collecting the foreign matters or dust in the groove to clean the sill 30, and transferring the collected foreign matters or dust to the receiving unit 52 for storage, so that the maintenance personnel only need to clean or replace the receiving unit 52 periodically, and do not need to use a dust collector or other work to perform dust collection treatment, thereby improving the cleaning efficiency and ensuring the safe operation of the elevator.

Specifically, the storage unit 52 is installed at one end of the elevator door 10 near the sill 30, and the storage unit 52 has a hollow housing-like structure having a storage cavity with one end open to store foreign materials and dust. The storage unit 52 may reciprocate along a first direction along with the elevator door 10, and when the elevator door 10 is switched from the fully closed state to the fully opened state, the storage unit 52 is located at the front end of the elevator door 10 in the moving direction.

Further, the storage unit 52 is detachably installed inside the edge of the elevator door 10, so that a maintenance person can conveniently replace or clean the storage unit 52. It is understood that the shape of the storage unit 52 is not limited and may be provided as needed to match elevator doors 10 of different shapes.

The dust collection unit 54 is installed at the elevator door 10 and located at a side of the storage unit 52 away from an edge of the elevator door 10, the dust collection unit 54 can reciprocate along a first direction along with the elevator door 10, and when the elevator door 10 is switched from a fully closed state to a fully opened state, the dust collection unit 54 is located at a front end of the elevator door 10 in a moving direction.

As shown in fig. 1 to 3, the dust collection unit 54 has a cleaning state to clean the doorsill 30 and a transferring state to transfer foreign substances and dust. When the dust collecting unit 54 is in the cleaning state, the dust collecting position 5436 is located in the sill 30, and the dust collecting position 5436 can sequentially collect the foreign matters and dust at different positions in the groove of the sill 30 along with the movement of the dust collecting unit 54. When the dust collection unit 54 is in the transfer state, the dust collection position 5436 is switched between a position within the groove of the sill 30 and a position toward the open end of the housing chamber, so that foreign substances and dust in the dust collection position 5436 fall into the housing unit 52 to be stored, or return to the groove after the transfer of the foreign substances and dust is completed to prepare for the next cleaning.

During the movement of the dust collection unit 54 in the first direction, the dust collection unit 54 is controllably switched between the sweeping state and the transferring state. Wherein, when the elevator door 10 is switched from the fully closed state to the fully opened state, the dust collection unit 54 is switched from the cleaning state to the transferring state. When the elevator door 10 is switched from the fully opened state to the fully closed state, the dust collection unit 54 is switched from the transit state to the cleaning state.

Thus, the cleaning device 50 can automatically clean the sill 30 along with the movement of the elevator door 10 without manual operation of the maintenance personnel, and the foreign matters and dust collected by the dust collection unit 54 can be automatically stored in the storage unit 52, and the maintenance personnel only need to regularly clean or replace the storage unit 52, thereby improving the cleaning efficiency and cleaning effect of the sill 30 and ensuring the stable and safe operation of the elevator door 10.

As shown in fig. 3 and 4, in some embodiments, the dust collecting unit 54 includes a rotating shaft 541, a gear 542, and a dust collecting member 543. The rotating shaft 541 is rotatably installed at the elevator door 10, and a central axis of the rotating shaft 541 extends in the second direction. The gear 542 and the dust collecting member 543 are respectively sleeved on the rotating shaft 541 and rotate synchronously with the rotating shaft 541. The dust collecting piece 543 is substantially "L" shaped, and includes a connecting section 5432 and a dust collecting section 5434 connected to each other, one end of the connecting section 5432 is sleeved on the rotating shaft 541, one end of the dust collecting section 5434 is connected to one end of the connecting section 5432 far away from the rotating shaft 541, and the other end of the dust collecting section 5434 extends obliquely towards the direction far away from the connecting section 5432 to form a dust collecting position 5436. In this way, the gear 542 can drive the rotating shaft 541 to rotate synchronously around the second direction, and further drive the dust collecting piece 543 to rotate synchronously around the second direction, so as to switch the dust collecting position 5436 between the position inside the sill 30 and the position facing the opening end of the accommodating cavity.

Further, the cleaning device 50 further comprises a driving unit 56, the driving unit 56 is provided on the hoistway wall, the driving unit 56 comprises a rack 561 extending in the first direction, the rack 561 can be engaged with the gear 542 of the dust collection unit 54, so that the dust collection unit 54 can be driven to switch between a position in the sill 30 and a position toward the open end of the receiving chamber.

Specifically, when the dust collection unit 54 is separated from the driving unit 56, the dust collection position 5436 of the dust collection unit 54 is in the sill 30 to collect foreign substances and dust. When the dust collecting unit 54 is coupled with the driving unit 56, the driving unit 56 and the dust collecting unit 54 move relatively in the first direction, the gear 542 of the dust collecting unit 54 is engaged with the rack 561 of the driving unit 56, the gear 542 rotates under the action of the rack 561 to drive the dust collecting piece 543 to rotate because the rack 561 is fixed in the hoistway wall, and after the dust collecting position 5436 rotates above the opening end of the receiving cavity of the receiving unit 52, the foreign matters and dust in the dust collecting position 5436 fall into the receiving cavity under the action of gravity to finish the storage of the foreign matters and dust.

In some embodiments, the dust collection unit 54 further includes a pivoting arm 544 and a resilient member 545. One end of the rotating arm 544 is connected to an end of the dust collecting section 5434 far from the connecting section 5432, and the other end of the rotating arm 544 extends obliquely toward the connecting section 5432. The elastic member 545 is connected between the rotation arm 544 and the dust collecting section 5434, and the elastic member 545 functions to apply a pushing force to the rotation arm 544 away from the dust collecting section 5434. In this way, when the dust collection unit 54 moves in the first direction to clean the groove of the sill 30, the foreign objects in front of the dust collection unit 54 enter the dust collection positions 5436 under the guiding action of the rotating arm 544, and the foreign objects in the dust collection positions 5436 are blocked by the rotating arm 544 and cannot fall out of the dust collection positions 5436, thereby effectively improving the cleaning effect. It will be appreciated that the angle between the rotating arm 544 and the dust collecting section 5434 is greater than 0 ° and less than 90 °, and the specific angle can be set as desired to meet different needs.

In some embodiments, the dust collection unit 54 further includes bristles that cover a side surface of the dust collection section 5434 remote from the connection section 5432. Because the bristles are soft and can deform obviously, the anti-blocking function can be achieved, and meanwhile, dead-angle-free cleaning can be performed on the grooves.

The cleaning process of the sill 30 of the above-described vertical elevator 100 is as follows:

when the elevator door 10 is switched from the fully closed state to the fully open state, the dust collection unit 54 moves in the first direction to collect foreign substances and dust in the groove of the sill 30 to the dust collection position 5436. When the dust collection unit 54 moves to the elevator shaft wall, the dust collection unit 54 contacts the driving unit 56, and as the dust collection unit 54 continues to move in the first direction relative to the driving unit 56, the driving unit 56 drives the gear 542, the rotating shaft 541 and the dust collection piece 543 of the dust collection unit 54 to rotate in the second direction, so that the dust collection position 5436 rotates above the open end of the receiving cavity of the receiving unit 52, and the garbage in the dust collection position 5436 falls into the receiving cavity.

When the elevator door 10 is switched from the fully opened state to the fully closed state, the dust collection unit 54 moves in a reverse direction with respect to the driving unit 56, the driving unit 56 drives the gear 542, the rotating shaft 541 and the dust collection piece 543 of the dust collection unit 54 to rotate in a reverse direction in a second direction, so that the dust collection position 5436 rotates from above the open end of the receiving cavity into the groove of the sill 30, and then the dust collection unit 54 continues to move in the first direction and gradually moves away from the driving unit 56 until the elevator door 10 is in the fully opened state.

Thus, through the arrangement of the cleaning device 50, the vertical elevator 100 of the present application can automatically clean the sill 30 when the elevator door 10 is opened at every time, thereby preventing the sill 30 from accumulating foreign matters and dust, and a maintainer only needs to clean or replace the storage unit 52 at intervals, and does not need to clean the whole sill 30, thereby improving the cleaning efficiency and ensuring the normal opening and closing of the elevator door 10. In addition, the cleaning device 50 may take the role of a door holding device to prevent the elevator door 10 from being separated from the sill 30, thereby providing a further guarantee for the safe operation of the elevator door 10. In addition, since the dust collection unit 54 can collect and transfer foreign materials and dust only by opening and closing the elevator door 10, there is no need to additionally provide power input, and the transmission manner is durable and reliable.

It is understood that the cleaning device 50 can be used not only for cleaning the sill of the elevator door 10, but also for cleaning other automatic door structures, and will not be described in detail herein.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
