Embodiment approach 1

[0032] figure 1 It is a schematic diagram showing the surroundings of the car of the elevator apparatus according to Embodiment 1 of the present invention. In addition, for convenience, the frontal width direction of the entrance and exit of the passenger car is set as the X direction, and the direction perpendicular to the frontal width direction of the passenger car in the horizontal plane, that is, the depth direction is set as the Y direction. The direction is set to the Z direction.

[0033] exist figure 1 Among them, the car 100 includes a passenger car 1 and a car frame 2 elastically supporting the passenger car 1 via vibration-proof rubber 3 , vibration-isolating rubber 4 , and the like. The active guide roller 5 has: a support platform 6, which is fixed to the car frame 2; a guide rod 7, which can be swingably installed on the support platform 6; and the actuator 10 drives the guide rod 7 to actively control the contact condition between the guide rail 8 and the gu...

Abstract

In the driving guide roller and the elevator apparatus according to the present invention, one of the actuator movable part and the actuator fixed part includes: a yoke having a middle leg part and a pair of yokes arranged opposite to each other across the middle leg part. the pair of side legs, the yoke constitutes a closed magnetic circuit; and a pair of magnets, which are provided on the respective faces of the pair of side legs opposite to the middle leg, to generate a force that intersects with the swinging face of the guide bar. In the magnetic field, the other of the actuator movable portion and the actuator fixed portion includes: a bobbin having a spool portion into which the middle leg portion is inserted; and a coil wound around the The bobbin part is arranged in the magnetic field, and when the movable part of the actuator is displaced in a direction perpendicular to the swing surface, the bobbin and the magnet or the winding wire The tube is in contact with the yoke, making it possible to prevent the coil from coming into contact with the magnet.

Description

technical field [0001] The invention relates to a drive guide roller and an elevator device for suppressing car swaying. Background technique [0002] In an elevator apparatus, a guide portion of a driving guide roller provided in a car comes into contact with a guide rail provided in a hoistway extending in the vertical direction, whereby the car moves up and down along the guide rail. Guide rails have steps and bends due to installation errors, car loads, and year-to-year changes. As a result, when the car is raised and lowered, it is disturbed by the external displacement caused by the step difference and bending of the guide rail, and the vertical vibration as the vibration in the lifting direction and the lateral vibration as the vibration in the direction perpendicular to the lifting direction are generated, so that passengers will feel uncomfortable. Come uncomfortable. [0003] In the past, in order to alleviate the displacement input of the longitudinal vibration ...
