no. 1 Embodiment approach
[0023] figure 1 It is a figure showing the schematic structure of the machine-room-less elevator of 1st Embodiment.
[0024] The elevator 1 has a hoistway 2 installed in a building, and a car 11 and a counterweight 12 are supported inside the hoistway 2 so as to be movable up and down via guide rails. Furthermore, a hoist 14 having a traction sheave 13 is installed on the upper portion of the hoistway 2 .
[0025] The car 11 and the counterweight 12 are suspended in the hoistway 2 via a plurality of main steel cables 10 . Furthermore, figure 1 Only one main steel cable 10 is shown in the figure, and the illustration of other main steel cables 10 is omitted.
[0026] The one end 3a and the other end 3b of the main wire rope 10 are fixed to the upper end of the hoistway 2 via rope locks 4a, 4b, respectively. In addition, the intermediate portion 3 c of the main wire rope 10 is continuously wound around a pulley 15 provided on the car 11 , a traction sheave 13 provided on the...
no. 2 Embodiment approach
[0080] Next, a second embodiment will be described.
[0081] In the above-mentioned first embodiment, the encoder 22 is provided on the car 11, and the pulse signal output from the encoder 22 is counted. A rotary encoder is used as the encoder 22, but a linear encoder (not shown) that magnetically or optically outputs pulses in the hoistway 2 along the ascending and descending direction of the car 11 may also be used.
[0082] Here, as the pulse generating unit, as long as it has a structure that generates a pulse signal substantially synchronously with the feeding amount of the main steel cable 10, that is, as long as it generates a pulse signal as the car 11 and the counterweight 12 move up and down. structure, the effect is the same. Therefore, the existing encoder installed in the elevator 1 for detecting the car position and speed can be used.
[0083] Next, the configuration in the case where an existing encoder is used as the pulse generator of this system will be des...
