Embodiment Construction

[0009] figure 1 It is an elevator device without a machine room. The device according to the invention can also be used in elevator installations with a machine room. The elevator driving device with pulleys is not shown in the figure, and the elevator car 2 is connected with the counterweight (not shown) through the pulleys to guide the cables to move up and down in the elevator passage 1 . The elevator car 2 can move along guide rails 3 . The elevator controller 4 installed on one of the floors controls the movement of the elevator driving device and the elevator car 2 and ensures the safety of the elevator operation. Elevator car 2 serves floors E1 and E2. In the exemplary embodiment shown, the elevator installation has two floors, but in practice it can also have more floors. The safety circuit of the elevator installation includes a series of circuits in contact with landing doors (not shown), the upper limit switch 5 and the lower limit switch 6 of the elevator passa...

Abstract

The position of the elevator car (2) in the hoistway is important for the elevator control (4). Therefore, there is a need for an apparatus for generating channel information. In an embodiment of the invention, the device comprises an encoding device (11) connected to a long toothed belt (10) stretched over the height of the passage for detecting the movement of the elevator car (2) absolute position. The coding device (11) installed on the elevator car (2) has a toothed wheel (12). When the elevator car (2) moves in the elevator passage (1), the toothed wheel can be (11) DRIVE. The guide rollers (13) ensure the safe meshing of the toothed wheels (12) in the toothed wheel mechanism (12) of the long toothed belt (10). Each end of the long toothed belt (10) is associated with a transverse support element (14). A toothed strap reinforcement acting as a tension cord ensures that the necessary strap tension is maintained.

Description

technical field [0001] The present invention relates to a device for generating passage information in an elevator passage, in which there is a barcode throughout the passage, wherein the barcode can be read by a sensor mounted on a movable elevator car in the elevator passage and converted into Operating parameters of the elevator car. Background technique [0002] No. 4,433,756 discloses a device for generating passage information, with which device the absolute position of an elevator car can be determined. A stretchable perforated strip tensioned throughout the passage is scanned with an optical readout device mounted on the elevator car. The perforated strip has two recording tracks, one recording track representing the car position in binary code and the other recording track having equally spaced openings throughout the strip. The first recorded track is scanned with one optical readout device and the second recorded track is scanned with two optical readout devices...
