Description

  Embodiments described herein relate generally to a hoist / lifter and an elevator manufacturing method.

  The elevator includes a basket room, a counterweight, a rope connecting the basket room and the counterweight, and a hoisting machine that winds up the rope.

  The hoisting machine is installed above the elevator hoistway. Therefore, when manufacturing an elevator, it is necessary to lift the hoisting machine from the lowermost floor of the hoistway to the installation place on the uppermost floor.

  Conventionally, a wire fixed to a pedestal on which the winder is placed is wound up by a winch to lift the winder.

  However, depending on the position of the scaffolding and the tower in the hoistway, it may be difficult to lift the hoisting machine to the installation location due to the scaffolding and the tower.

  FIG. 5 is a diagram showing the pedestal 101 and the first moving device 102A. In FIG. 5, the illustration of the frame 102 is omitted. As shown in FIG. 5, the pedestal portion 101 includes a flange portion 101 </ b> B that protrudes in the direction of the frame 102 on the side surface portion.

  The first moving device 102A includes a bearing 102B that grips the flange portion 101B from above and below. Accordingly, the pedestal portion 101 is positioned in the vertical direction by the first moving device 102A, and can slide in the horizontal direction from the center of the hoistway toward the wall of the hoistway where the counterweight is installed in proximity. Become.

  The pedestal unit 101 includes a second moving device 101A on a flat surface on which the hoisting machine 301 is placed. The second moving device 101A has, for example, a plurality of bearings. The second moving device 101A may be a belt conveyor.

  In the second moving device 101A, the second moving device 101A mounts the hoisting machine 301 in a slidable manner.

  FIG. 6 is a diagram showing a case where the lifting machine 1 is located near the lowest floor of the hoistway. As shown in FIG. 6, the hoisting machine 301 is placed on the pedestal 101. The lifting machine 1 is supported by a pair of rails 201 for positioning a counterweight by a roller guide 103A.

  One end of a wire 401 is attached to the hanging base 104, and the other end of the wire 401 is attached to a tower. A winch 402 is provided in the middle of the wire 401.

  When the winch 402 winds up the wire 401, the lifting machine 1 moves in the hoistway toward the uppermost floor.

  FIG. 7 is a diagram illustrating a case where the lifting machine 1 is located near the tower 202 on the top floor of the hoistway. As shown in FIG. 7, when the installation position of the hoisting machine 301 is at the upper part of the tower 202, it is necessary to lift the hoisting machine 301 while avoiding the tower 202.

  In this case, the first moving device 102A moves the hoisting machine 301 together with the pedestal 101, in the direction avoiding the tower 202, that is, in the horizontal direction from the wall surface of the hoistway where the counterweight is installed close to the center of the hoistway. Then, the wire 401 is moved in the direction of the arrow X 1, and the wire 401 is wound up by the winch 402.

  Therefore, the hoisting machine 301 can lift up to a height that matches the upper surface of the tower 202.

  A third moving device 203 such as a bearing is installed at the installation position of the hoisting machine 301 of the tower 202.

  FIG. 8 is a diagram illustrating a state where the hoisting machine 301 is moved to the installation position. As shown in FIG. 8, in the hoisting machine 301, the counterweight is moved closer to the installation position from the top of the pedestal 101, that is, from the center of the hoistway, by the second moving device 101A and the third moving device 203. Are moved in the direction of the arrow X2 in the horizontal direction toward the wall surface of the hoistway installed.

  When the hoisting machine 301 reaches the installation position, the hoisting machine 301 is lifted with a jack, the third moving device 203 is removed, and the hoisting machine 301 is lowered again with the jack to the installation position.

  FIG. 9 is a flowchart showing an installation process of the hoisting machine 301 using the lifting machine 1. As shown in FIG. 9, in step 901, the worker first installs the lifting machine 1 near the lowest floor of the hoistway. That is, the roller guide 103 </ b> A is installed on the rail 201 for positioning the counterweight, and is attached to the rail 201 so that the lifting machine 1 can move up and down along the rail 201.

  In step 902, the worker hangs the suspension base 104 from the tower 202 by the wire 401 by connecting the suspension base 104 and the tower 202 by the wire 401 through the winch 402.

  In step 903, the worker places the hoisting machine 301 on the pedestal 101 of the lifting machine 1.

  In step 904, the operator lifts the lifting machine 1 by winding the wire 401 with the winch 402.

  In step 905, the worker moves the pedestal 101 by the first moving device 102 </ b> A in the horizontal direction from the wall surface of the hoistway where the counterweight is installed close to the center of the hoistway, and the tower 202 is moved. To avoid.

  In step 906, the operator further raises the lifting machine 1 by winding the wire 401 with the winch 402.

  In step 907, the operator installs the hoisting machine 301 at the installation position with the second moving device 101 </ b> A and the third moving device 203 installed in the tower 202 close to the counterweight from the center of the hoistway. Move horizontally toward the wall of the hoistway.

  In step 908, the worker lifts the hoisting machine 301 with a jack, removes the third moving device 203, and lowers the hoisting machine 301 again.

  As described above, the lifting machine 1 of the present embodiment moves the pedestal portion by the first moving device 102A in a direction avoiding obstacles such as the tower 202, and lifts the hoisting machine 301 to the height of the installation position. The hoisting machine 301 is moved to the installation position by the second moving device 101A.

  Therefore, even if there is an obstacle such as a scaffold or a tower in the hoistway, there is an effect that the hoisting machine can be easily lifted to the installation location.

  Although several embodiments have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
