Embodiment

[0026] A kind of elevator hall door system in this embodiment, such as Figure 6 As shown, it includes an upper sill 6 with guide rails and two hall doors. The hall door of this embodiment is a side-opening form, and the two hall doors adopt an embedded structure. The two hall doors are the first hall door with a long opening and closing stroke and the second hall door with a short door opening and closing stroke. The first hall door is composed of a first door panel 21 and a first hanging plate 31 arranged on the top of the first door panel. The second hall door is composed of a first door panel 22 and a first hanging plate 32 arranged on the top of the first door panel, and two pulleys 4 are installed in parallel distribution at the upper edges of the first hanging plate and the second hanging plate. like Figure 8 As shown, the upper sill includes a body, which is bent along the length direction and has an L-shaped structure in cross-section. In this way, an upper flat pla...

Abstract

The invention relates to an elevator hoistway door system and solves the problems that an existing elevator hoistway door system has low utilization rate for the space of a shaft and due to adoption of a steel wire rope for linkage, the existing elevator hoistway door system has a complex structure and is inconvenient to install. The elevator hoistway door system comprises a hoistway door and an upper sill with guide rails; the hoistway door comprises door sheets and hanging plates connected to the upper parts of the door sheets; sliding wheels are respectively arranged on two hanging plates; the two hanging plates are connected to the guide rails in a sliding manner by the sliding wheels; two door sheets are of an embedded structure; and traction mechanisms are arranged between the two hanging plates. The hoistway door adopts the embedded design, so that the two door sheets only occupy the space of one door sheet originally and a door opening only needs to be formed on one side of a lift car, so that the space is saved and the utilization rate of the shaft is improved. The traction mechanisms capable of drawing each other are arranged between the hanging plates corresponding to the two door sheets, so that a complex steel wire rope linkage mechanism in an existing upper sill is omitted and the elevator hoistway door system has a simpler structure, and is low in cost, light in weight and easy to install on site.

Description

[0001] technical field [0002] The invention relates to the technical field of elevators, in particular to an elevator hall door system with small footprint, light weight, simple structure and convenient installation. Background technique [0003] At present, the elevator door opening methods commonly used in the market are: middle split door, side door, middle split bifold door, etc. The middle split door means that the two door panels are opened from the center of the door to both sides at the same time, and closed from both sides to the center of the door when the door is closed. The side opening door is composed of two door panels, one fast and one slow. When opening the door, it opens from one side of the door opening to the other side, and the opposite is true when closing the door. The principle of opening and closing doors of the elevator door system is powered by the car door system to drive the hall door system. Realize the function of opening and closing the doo...
