Embodiment Construction
[0041] Such as figure 1 As shown, the lift landing door 11 and the car door 8 clearance compensating device of the present invention are symmetrically installed on the back of the car door 8 . It includes a gap filling plate 1, a torsion spring 2, a wire rope guide wheel 3, a wire rope guide tube 4, a wire rope 5, a slider assembly 6, a hook assembly 7, and a contact switch 15.
[0042] Said caulking plate 1 is an L-shaped structure, which shares a shaft with the torsion spring 2, and is symmetrically installed on the closing sides of the left and right car doors 8. When the car door 8 is closed, the caulking plate 1 is parallel to the panel of the car door 8, and the elevator runs up and down safely; The gap 14 between 11 realizes this design purpose.
[0043] Such as figure 2 , image 3 As shown, when the elevator runs up and down, the car door 8 and the landing door 11 are closed, and the caulking plate 1 is in a closed state. When the leveling car door and landing do...

The invention provides an elevator car door and landing door gap compensation device, an elevator using the device and a method. The device is composed of a gap filling plate, a torsion spring, a steel wire rope assembly, a steel wire rope guide wheel, a steel wire rope guide pipe, a sliding block assembly, a hook assembly and the like; gap filling plate is arranged on the side of a car door, along with opening of an elevator door, the gap filling plate is gradually opened under the effect of the torsion spring until the gap between a car door and a landing door is completely filled up; when an elevator door is closed, a hook provides the pull force effect, the gap filling plate is gradually and rotatably closed, and elevator running safety and reliability are ensured. The device is of a pure mechanical structure, the structure is simple and rapid, the manufacturing cost is low, mounting is convenient and rapid, opening and closing of the gap filling plate are in flexible transition, the device is safe, reliable, free of noise and wide in application range.
Description
technical field [0001] The present invention relates to an accessory on the side of an elevator car, an elevator using the accessory, and a method of using the accessory. Background technique [0002] In the current elevator design, the car door and the landing door run in the sill, and a certain gap must be left between the car door sill and the landing door sill to ensure that the car runs smoothly up and down. When the elevator door is opened, the gap between the car door and the landing door is large, and the gap is within the reach of human hands. In order to prevent passengers or maintenance personnel from being accidentally pinched by the gap when the elevator door is open, the gap compensation device is added to improve the safety of the elevator. [0003] At the same time, due to the gap between the car door and the landing door, it has a certain impact on the integrity and aesthetics of the elevator landing door car door, reducing the passenger's sense of security...
