Two-way opening elevator

Abstract

The invention discloses a two-way opening elevator. The two-way opening elevator comprises a car system which comprises a square bottom tray (1). Vertical uprights (2) are arranged on four corners of the bottom tray (1), a top crossbar is arranged on the top of the vertical uprights (2), and the bottom tray (1), the vertical uprights (2) and the top crossbar are integrated to be an outer frame of the car system. Inner surfaces of the vertical uprights are arc shaped, arc-shaped car walls (3) are disposed in the vertical uprights and are provided with two identical notches the sizes and positions of which correspond to two doors of an elevator floor, and the two doors of the elevator floor are disposed on a hoistway of the elevator and correspond to two adjacent edges of the bottom tray (1). A cylindrical car door (4) is arranged between the vertical uprights (2) and the car wells (3) and is opened with a notch the size of which corresponds to that of the door of the elevator floor, and the car door (4) rotates on the vertical uprights (2) and the car walls (3). When the notch turns to a position corresponding to the door of the elevator floor, opening in one way is realized.

Description

technical field [0001] The invention relates to an elevator, in particular to an elevator with two-way doors. Background technique [0002] In order to adapt to various buildings, various elevators with multi-directional door openings have appeared on the market. The door opening position of the existing elevator car is usually set in one direction or two opposite directions of the elevator car, and there are also a small number of elevator car door opening positions in two directions perpendicular to each other or the elevator car in the direction of the three positions. [0003] However, for the door-opening elevators in two adjacent directions, due to the structural limitations of the double-door door machine, it is more difficult to realize. Moreover, the use of two or more door operators is likely to cause problems with the counterweight of the elevator car. Therefore, it is necessary to adjust the counterweight to make the elevator car return to balance, but this wil...

Problems solved by technology

[0003] However, for the door-opening elevators in two adjacent directions, due to the structural limitations of the double-door door machine, it is more difficult to realize

Moreover, the use of two or more door operators is likely to cause problems with the counterweight of the elevator car. Therefore, it is necessary to adjust the counterweight to make the elevator car return to balance, but this will inevitably increase the weight of the elevator car, which will cause serious damage to the elevator traction machine. Increased burden and increased energy consumption
