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 and 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 rop...

Abstract

One kind of no mechanical room elevator is provided, which has more effective spaces over and below the elevator car and minimized size of elevating passage for installation and maintenance. In the elevator, the winch suspends and drives two sides of the elevator car via the slings, and the slings set on two sides of the elevator car are wound through the pulley and deflecting pulley onto the winch in the sling winding ratio of 1 to 1. The slings wound onto the winch are combined as one sling set with sling winding ratio in the balance weight side of 2 to 1. In addition, the winch, the pulley and the deflecting pulley are configured 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 and 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 and 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 t...
