Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a floor-penetrating device for a hoistway-free elevator. Background Art

[0002] As an indispensable equipment in modern buildings, elevators are powered by electric motors or hydraulic systems and run along vertical rails, providing people with a fast and convenient vertical transportation method. Its safety, efficiency and comfort make it an indispensable part of buildings, providing passengers with a comfortable riding experience, while also improving the overall efficiency and functionality of the building. The elevator floor-penetrating device is a device used to enable the elevator to reach the target floor directly in a multi-story building. It usually consists of an additional transmission mechanism and a guide system, which allows the elevator to cross multiple floors in the vertical direction without stopping. The main function of this device is to improve the operating efficiency and convenience of the elevator, reduce the waiting time of passengers, and optimize the use of building space. Through the elevator floor-penetrating device, passengers can reach their destination more quickly, improving the operating efficiency of the elevator system, while also enhancing the functionality and convenience of the building.

[0003] The prior art (publication number: CN 210117138U) discloses a floor-penetrating device for a shaftless elevator and a shaftless elevator, which relates to the technical field of shaftless elevators and solves the technical problem that the vertical height of the existing shaftless elevator flap is relatively high after opening, which easily affects the normal operation of the elevator. The floor-penetrating device for a shaftless elevator includes a folding cover plate and a pivot, the folding cover plate is composed of a plurality of folding units, each two adjacent folding units are hinged, and the folding unit adjacent to the pivot is pivotally connected to the pivot; the folding cover plate can cover the floor-penetrating opening of the elevator, and when the folding cover plate rotates along the pivot, the plurality of folding units are folded or unfolded to open or close the floor-penetrating opening;

[0004] Although the height of the folding unit of the above patent is low when the through-layer opening is opened, that is, the height of the folding cover is low after folding, which is not easy to affect the normal operation of the elevator, and the elevator running speed can be increased accordingly; and the torque on the pivot is reduced, which is conducive to the stable and reliable operation of the elevator without a shaft, but there are the following disadvantages. When in use, the folding cover is driven by two sets of motors to fold. However, if the two motors move asynchronously, the opening or closing of the folding cover may be uneven, thereby affecting the stability and safety of the elevator, increasing the cost and workload of maintenance and repair, and further improvement is needed. For this reason, we propose a through-layer device for a shaftless elevator. Utility Model Content
