no. 1 approach example

[0028] 1-1. Structural Example of Elevator

[0029] First, refer to Figure 1 ~ Figure 3 The structure of the elevator of 1st Embodiment (henceforth "this example") is demonstrated.

[0030] figure 1 It is a schematic configuration diagram showing a configuration example of the elevator of this example. figure 2 It is a top view showing the elevator of this example.

[0031] figure 1 The illustrated elevator 1 is a so-called multi-car elevator in which an elevator car representing an example of an elevator body moves up and down in one hoistway formed in a building structure. in addition, figure 1 The shown elevator 1 is a circular elevator in which the lifting body circulates between two pulleys.

[0032] Such as figure 1 As shown, elevator 1 has: a plurality of elevator cars 120A, 120B (two in this example) carrying people or goods; two main ropes 130A, 130B; two upper pulleys 150A, 150B; and two lower The pulleys 160A, 160B. In addition, the elevator 1 further incl...

no. 2 approach example

[0125] Next, refer to Figure 10 An elevator according to a second embodiment will be described.

[0126] Figure 10 It is an explanatory diagram showing the retraction mechanism of the second embodiment.

[0127] The elevator of this second embodiment differs from the elevator 1 of the first embodiment in the structure of the retraction mechanism and the first member of the drive unit. Therefore, here, the retraction mechanism and the driving unit will be described, and the same reference numerals will be attached to the parts common to the elevator 1 according to the first embodiment, and overlapping descriptions will be omitted.

[0128] Such as Figure 10 As shown, the drive units 40A to 40C have the first member 41 and the second member 22 facing each other across the main cables 130A and 130B. In addition, retraction mechanisms 50A to 50C are respectively provided in the drive units 40A to 40C. The retraction mechanisms 50A to 50C are arranged on the opposite side o...

Abstract

Provided is an elevator and a control method of an elevator capable of passing a thick portion of a main rope through a drive device. An elevator (1) includes a main rope (130A) circulating between two pulleys (150A, 160A); an elevating body (120A) connected to the main rope (130A); and a linear drive device (10) for generating thrust on the main rope (130A). The linear drive device (10) includesa drive unit (10A) and a retraction mechanism (11A). The drive unit (10A) includes a first member (21) and a second member (22). The retraction mechanism (11A) brings the first member (21) closer to and away from the main rope (130A). The retraction mechanism (11A) retracts the first member (21) away from the main rope (130A) when the thick portion (5) formed in the main rope (130A) passes betweenthe first member (21) and the second member (22).

Description

technical field [0001] The present invention relates to an elevator in which a lifting body such as an elevator car and a counterweight circulates between two pulleys and a control method for the elevator. Background technique [0002] As a driving method for moving the lifting body such as the elevator car and counterweight, in addition to the traction method using a hoist, it has also been proposed to make the main cable itself generate a driving force by flowing an induced current in the main cable connected to the lifting body ( Thrust) linear drive elevator. [0003] As a conventional linear drive type elevator, there is an elevator described in Patent Document 1, for example. Patent Document 1 describes an elevator that is fixed to a building and includes a cylindrical primary winding through which a main rope passes, and a main rope serving as a secondary conductor. [0004] In addition, in recent years, there has been demand for a circular elevator in which an elev...
