Embodiment Construction

[0016] Embodiments of the elevator without a machine room according to the present invention will be described below with reference to the drawings.

[0017] figure 1 It is a plan view of an elevator without a machine room according to an embodiment of the present invention, figure 2 for figure 1 main view.

[0018] exist figure 1 with figure 2 , the elevator car 102 and the counterweight 103 move up and down in the hoistway 101 . A guide device (not shown) is installed above and below the sides of the elevator car 102 and the counterweight 103, and guided by the guide device, the elevator car 102 moves up and down along the elevator car guide rails 104a, 104b. Like the elevator car 102, the counterweight 103 smoothly moves up and down along the counterweight guide rails 105a, 105b in the hoistway without inclining the elevator car.

[0019] In addition, in the elevator car 102, the side portions near the center of gravity pass through fixed ropes 106a, 106b (one ro...

Abstract

To provide an elevator without a machine room, which can ensure more effective space above and below the elevator car, and can be installed, repaired and maintained with the size of the hoistway which is the minimum necessary for the size of the elevator car . In the elevator without a mechanical room, the hoist (111) is suspended to drive the two sides of the side of the elevator car (102) by means of slings (106a, b), wherein the slings are arranged on the left and right sides of the elevator car. The left and right slings (106a, b) are respectively wound on the winch through the pulleys (108a, b) and deflection pulleys (110a, b), and the winding ratio of the slings on the side of the elevator car is 1:1. The left and right slings that have been wound on the hoist are used as a set of slings so that the winding ratio of the slings on the counterweight side (103) is 2:1, and the hoist and the pulley and The configuration position of the diverting pulley is outside the vertical projection of the elevator car.

Description

technical field [0001] The present invention relates to a machine room-less elevator in which both sides of the side of the elevator car are suspended by slings, and the ratio of sling winding (roping) on ​​the side of the car to the side of the counterweight is different. Background technique [0002] As existing elevators such as image 3 with Figure 4 The shown elevator without a machine room (for example, refer to Japanese Patent Laid-Open No. 2000-351552, which is Patent Document 1). image 3 is the top view of the existing elevator without machine room, and Figure 4 for image 3 main view. [0003] exist image 3 with Figure 4 Among them, 1 represents the wall surface of the hoisting passage where the elevator car 2 and the counterweight 3 go up and down, 4 represents the sling, 5 and 6 represent the diverting pulleys, 8 represents the beam supporting the diverting pulleys 5 and 6 arranged at the top of the hoisting passage, 9 Represents the motor, 10 represents...
