Abstract

The invention provides a position adjusting device and an elevator device, wherein the position adjusting device can facilitate maintenance in the elevator device, and the elevator device is provided with the position adjusting device. The position adjustment device is provided with an upper vibration-proof member fixed to a position lower than a first device fixed to a hoistway and arranged to a position upper than a second device adjacent to a control cable, and a lower vibration-proof member arranged to a position lower than the second device. The upper vibration isolator and the lower vibration isolator each have a base portion fixed to the hoistway, and a rotating portion capable of changing a rotational position relative to the base portion and contacting the control cable. The distance between the second device and the control cable when the respective rotation portions of the upper vibration isolator and the lower vibration isolator are located at a second rotation position different from the first rotation position is longer than the distance between the second device and the control cable when the respective rotation portions of the upper vibration isolator and the lower vibration isolator are located at the first rotation position.

Description

Position adjusting device and elevator device Technical Field The present invention relates to a position adjustment device and an elevator apparatus. Background Patent document 1 discloses a lead wire supporting device for an elevator. The leads are also referred to as control cables. The lead supporting device of patent document 1 includes a lead fixing member that fixes one end of a lead, and a lead vibration preventing member that holds the lead below the lead fixing member. The lead vibration isolation member includes a fixing portion that is fixed in the hoistway, and a rotating portion that is coupled to the fixing portion, is rotatable relative to the fixing portion, and includes a holding portion that holds the lead. Prior art literature Patent document 1 Japanese patent laid-open No. 2009-126640 In patent document 1, one end of a lead wire, i.e., a control cable, is connected to a junction box fixed in a hoistway. Although not described in patent document 1, other devices may be provided below the junction box. In this case, since the control cable passes through the front surface of the equipment provided below the junction box, there is a problem that maintenance work of the equipment is difficult to perform. Disclosure of Invention The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a position adjustment device capable of facilitating maintenance in an elevator apparatus, and an elevator apparatus provided with the position adjustment device.
