Description

  The present invention relates to an adjustable fixing device for an elevator guide rail and an elevator system including the same.

  In Patent Document 1, a reinforcing material is provided in the rail gauge direction of a pair of guard rails for the purpose of increasing the seismic strength of existing elevator guide rail fixing brackets with low man-hours and low noise, and providing an elevator that is safe against earthquakes. The technology to add is described.

Japanese Utility Model Publication No. 4-56179

  The guide rails of the elevator are laid along the vertical direction in the building hoistway.

  Conventionally, as a method of fixing the guide rail to the building, the rail bracket is fixed to the building concrete wall via a fixing material called a rail bracket with an anchor bolt, or the rail is attached to the building beam or the fastener plate attached to the building beam. The bracket is fixed by welding. Since the car moves up and down along the guide rails of the elevator, the installation accuracy of the guide rails greatly affects the riding comfort of the elevator. When installing the rail bracket, the rail bracket is fixed to the building after centering the rail, but once the rail bracket is fixed to the building hoistway wall or fastener plate, it is difficult to remove the rail bracket. . For this reason, much time and labor are required for the installation work of the rail bracket. When the rail is tilted and installed, there is a problem that the rail bracket must be once removed and the guide rail and the rail bracket must be installed again.

  In addition, when an earthquake occurs after the guide rails are installed (after the elevator is moved), elevators such as a car or counterweight may collide with the guide rails, causing displacement in the elevator guide rails. is there. In addition, buildings with seismic isolation structures may be displaced by earthquakes or winds. Since the guide rail is fixed to the building via the rail bracket, the guide rail follows the displacement of the building and the guide rail itself is displaced. Even if the guide rail is firmly fixed to the building, if the building itself is displaced, the rail is displaced.

  In order to correct the displacement generated in the guide rail, as described above, in the current structure, the building and the guide rail need to be separated and corrected once. For this reason, there is a problem that the rail bracket fixed to the building by anchor bolts or welding is once removed, the guide rail is centered again, and the new rail bracket is used to re-fix the building to the building.

  In the reinforcing apparatus for an elevator guide rail fixing bracket described in Patent Document 1, the reinforcing material is long and may occupy a wide area in the hoistway. The technique of this document reinforces the guide rail fixing bracket, but does not allow the position of the guide rail to be adjusted.

  Therefore, the object of the present invention is to provide a guide rail when there is a problem with the installation of the guide rail of the elevator and the guide rail is displaced or when the guide rail is displaced due to an earthquake or wind. Without removing the bracket, it is possible to easily adjust and correct the deviation or displacement and return it to its original state.

  The present invention includes a pedestal fixed to the wall surface of the hoistway, a movable plate installed on the pedestal, a rail fixing member installed on the movable plate, and a positioning member having a rotating shaft fixed to the pedestal. In the elevator guide rail adjustable fixing device installed on the rail bracket for fixing the elevator guide rail, the position of the movable plate can be adjusted with respect to the base by the positioning member.

  According to the present invention, the distortion of the guide rail of the elevator can be easily removed, and safe operation of the elevator system can be ensured without removing the rail bracket.

  The present invention includes a pedestal fixed to the wall surface of the hoistway, a movable plate installed on the pedestal, a rail fixing member installed on the movable plate, and a positioning member having a rotating shaft fixed to the pedestal. In the adjustable fixing device for the elevator guide rail installed on the rail bracket for fixing the guide rail of the elevator, the position of the movable plate can be adjusted with respect to the pedestal by the positioning member.

  Thereby, the displacement of the guide rail can be easily corrected and adjusted, and safe operation of the elevator system including the adjustable fixing device for the guide rail can be ensured.

  Hereinafter, embodiments will be described with reference to the drawings.

  FIG. 1 shows the overall configuration of an elevator system.

  In this figure, the elevator system is composed of a car 6, a wire rope 51 that suspends the car 6, a counterweight 7, a hoisting machine 8 that winds the wire rope 51, a control unit 9, etc., and is installed in the hoistway 1. ing.

  The car 6 moves up and down along a guide rail 2 (car side guide rail) laid in the vertical direction on the hoistway 1. The guide rail 2 of the car 6 is fixed to a building concrete wall (inner wall of the hoistway 1) with an anchor bolt via a fixing material called a rail bracket 4 (car side rail bracket). Or the guide rail 2 is being fixed to the building plate or the fastener plate attached to the building beam by welding.

  Here, a plurality of rail brackets 4 are provided, and the guide rails 2 are fixed to the building concrete wall at a plurality of locations in the vertical direction. Similarly, the guide rail 3 (the counterweight side guide rail) of the counterweight 7 is also fixed via the rail bracket 5 (the counterweight side rail bracket).

  When an earthquake occurs, the car 6 and the counterweight 7 vibrate on the guide rails 2 and 3, and an abnormal force is applied to the guide rails 2 and 3. This force may cause displacement of the guide rails 2 and 3. In addition, when the building has a seismic isolation structure, the building is displaced above and below the seismic isolation layer by an earthquake or wind. Since the guide rails 2 and 3 are fixed to the building via the rail brackets 4 and 5, the guide rails 2 and 3 are also displaced in accordance with the displacement of the building.

  FIG. 2 is a perspective view showing a state where the guide rails of the elevator are displaced.

  In this figure, the guide rail 2 (elevator guide rail) is deformed at the center due to the displacement of the upper and lower parts of the building, and the rail bracket 4 is also displaced.

  In the present embodiment, since the rail bracket 4 has an adjustment function, the deformation of the guide rail 2 and the displacement of the rail bracket 4 as described above can be corrected.
