Description

  The present invention relates to an elevator seismic rail support device that supports an elevator car that moves up and down or a guide rail that guides a counterweight against shaking during an earthquake.

  The guide rail is attached to the building's housing via the sliding support device, and even if the building's housing is displaced laterally, the sliding support device operates so that the guide rail does not follow the displacement, and the elevator car becomes the guide rail. It can be moved along (see, for example, Patent Document 1).

JP-A-9-278314

However, if the two guide rails arranged on the left and right sides of the car are separately supported by dampers, the two guide rails will move in the same direction as, for example, the front side of the car and the back side of the car as the earthquake shakes. It is sufficient to shake, but when one moves to the front side and the other moves to the opposite side, a large torsional force acts on the car, and in some cases, the car is destroyed.
In addition, if the left and right guide rails are swung away from the hoistway wall, they may be disengaged from the cage of the guide rail from the cage guide device.

  The present invention has been made to solve the above-described problems, and provides an elevator seismic rail support device that supports a guide rail that guides a car without twisting it even if a shake occurs during an earthquake. With the goal.

  An elevator seismic rail support device according to the present invention is an elevator seismic rail support device that supports a rail bracket of a guide rail that guides an elevator elevator car. An integrated frame to which the guide rail is attached, a support member attached to the wall of the hoistway, a link device that supports the integrated frame with respect to the support member, and a spring-equipped hydraulic damper.

  The elevator seismic rail support device according to the present invention has a guide rail for guiding a car attached to a substantially U-shaped integrated frame surrounding the car from three sides, and is linked to a support member attached to the inner wall of the hoistway. Since the guide rail is flexibly supported by the mechanism and the hydraulic damper with the spring, and the guide rail swings integrally with the integral frame and moves in the same direction, there is an effect that the guide rail does not twist the car.

To do. And the guide rail 5 is attached to the substantially U-shaped integral frame 3 surrounding the cage | basket | car 1 from three directions.
And the elevator seismic-rail support apparatus which concerns on Embodiment 1 of this invention is the support member 9,10,11,12 attached to the inner wall 2 of a hoistway, the support member 9,10,11,12, and the car 1, , A link mechanism 8 that connects the support members 9, 10, 11, 12 and the integrated frame 3, and a spring-loaded hydraulic damper 7.

The integral frame 3 is substantially U-shaped and includes three frames 3a, 3b, and 3c. And the guide rail 5 is being fixed to the frame 3a and the frame 3c by the rail clip 5a. The corners of the integrated frame 3 are reinforced by the reinforcing plate 3d.
In the link mechanism 8, the link 8a and the link 8b are rotatably supported by link pins 8c. The link mechanism 8 is rotatably supported by the pins 8d with respect to the support members 9, 10, 11, and 12, and the integrated frame 3 Alternatively, the reinforcing plate 3d is rotatably supported by a pin 8e.
