- the wheel 92 is provided with four second contact rollers 87.
- the outer periphery of each second contact roller 87 Is made of a high friction material.
- the outer periphery of each second contact roller 87 is in contact with the driving cord 33.
- Each second contact roller 87 is disposed inside the wheel 92 and is disposed around the powerful driving cord 33.
- Each second contact roller 87 regulates the displacement of the driving cord 33 in the direction perpendicular to the axis of the second rotating body 89 with respect to the second rotating body 89.
- Each second contact roller 87 is rotatable about a second rotation axis 95 that is inclined with respect to the center line of the drive cord 33 when vertically projected onto the drive cord 33. Yes.
- the inclination angle formed between the second rotary shaft 95 and the center line of the driving rope 33 when each of the second contact rollers 87 is vertically projected onto the driving rope 33 is set to [rad]. .
- Each second contact roller 87 rotates while contacting the driving cord 33 so as to leave a spiral trajectory on the outer peripheral surface of the driving cord 33 by rotating the second rotating body 89. It is getting moved.
- the first rotator 78 and the second rotator 89 are rotated in directions opposite to each other around the axis of the cylindrical portion 72. Further, the rotation speed of the first rotating body 78 and the rotation speed of the second rotating body 89 are the same.
- each first contact roller 76 and the rotation shaft 95 of each second contact roller 87 are the center of the drive cord 33 when vertically projected onto the drive cord 33. Inclined in opposite directions with respect to the line. Further, when each of the first and second contact rollers 76 and 87 is vertically projected onto the driving rope 33, each of the first rotating shaft 85 and the second rotating shaft 95 and the driving rope 33 are The absolute values of the inclination angles formed by the center line are the same.
- the first and second driving devices 73 and 74 are respectively rolled while the first contact rollers 76 and the second contact rollers 87 are in contact with the driving cord 33,
- the driving rope 33 is moved together with the counterweight 7 with respect to the driving rope 33 in the length direction.
- Other configurations are the same as those in the second embodiment.
- a base 71 having a cylindrical portion 72 is provided on the counterweight 7, and a first drive device 73 is provided on the inner side of the cylindrical portion 72, and a second Since the first and second drive devices 73 and 74 are formed as a single body by providing the drive device 74 on the outer side of the cylindrical portion 72 so as to surround the cylindrical portion 72, the fifth embodiment and Similarly, the first and second drive devices The movement of the devices 73 and 74 with respect to the driving cord 33 can be further stabilized, and the installation space for the driving device can be reduced.
- the driving rope 33 is penetrated as a penetrating body in the first and second driving devices, but the main suspending force 6 and the counterweight 7 are suspended.
- the cable 4 may be passed through the first and second drive devices as a penetrating body.
- the first and second drive devices are provided on the support member in the hoistway 1.
- Embodiments 5 and 6 the driving rope 33 stretched in the hoistway 1 is used as a track body, but the cylinder 41 in Embodiment 3 or the driving in Embodiment 4 is used. Use the rod-shaped member 51 as a track!
- each contact roller only touches the penetrating body.
- Each contact roller may be pressed against the penetrating body. That is, the contact roller may be urged by a spring (elastic body) in a direction in contact with the penetrating body. In this way, the sliding of the contact roller with respect to the penetrating body can be further suppressed, and the force 6 and the counterweight 7 can be raised and lowered more stably.
- a spring elastic body
