Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting guide device for an elevator guide rail.

[0002]

2. Description of the Related Art Generally, an elevator is provided with a pair of guide rails 3 and 4 for guiding a car 1 and a counterweight 2 as they ascend and descend, respectively, in a hoistway as shown in FIG. At the time of installation, the guide rails 3 and 4 are erected upright in order from the lower part of the hoistway.

By the way, in this erection work, guide rails are erected in order from the lower part of the hoistway, and centered and fixed to the hoistway wall (fastener in the case of a steel frame structure) at a certain pitch. .. The bottom guide rail is erected and centered and fixed using a scaffold (not shown), while the guide rails above it support the gondola or car suspended above the hoistway. A frame with a work floor is lifted in sequence while being raised, and centered and fixed to the hoistway wall.

Next, a method of hoisting the guide rails in this standing work will be described with reference to FIG. The operator 7 is guided by the left and right guide rails 5 that have been already fixed upright, and is mounted on the work floor 6 assembled to the car frame, and then the rope 8 connected to the guide rail lifting winch (not shown) Guide rail 9 to be connected (hereinafter,
(The guide rail 9) is hung, and both the work floor 6 and the guide rail lifting winch are operated to control them so that they have almost the same speed, and the guide rail 9 collides with other equipment installed in the hoistway. To prevent this, the operator 7 lightly supports and raises. When one speed becomes faster than the other speed during this ascending, first stop both, then raise the delayed one and stop when reaching the desired position, and then both By driving, the guide rail 9 is raised to a predetermined position.

After ascending to the predetermined position in this way, both of them are stopped, and the bottom 9a of the guide rail 9 is lifted by the guide rail lifting winch to a position where the bottom 9a of the guide rail 9 is aligned with the upper end of the upper end 5a of the guide rail 5 which has already been set up. Let Thereafter, the worker 7 manually moves the guide rail 9 to the upper end 5a of the guide rail 5 which has been erected upright, and fastens the two with fastening bolts.

[0006]

However, in the conventional method of hoisting the guide rail, the worker must support the guide rail by hand when raising the guide rail as described above, which is very dangerous. is there. In particular, it is practically difficult to make the speed of the work floor and the speed for lifting the guide rails exactly the same. Since the guide rails move up and down relatively, it is very difficult and dangerous to stop and operate the guide rails repeatedly by hand to lift them up to a predetermined position while supporting them by hand. In order to prevent the guide rail from colliding with other equipment even if the operator's hand is separated from the guide rail for some reason, the position of the hoisting part above the hoistway where the guide rail is hoisted is There is a problem that it can not be set to the center of gravity position, and after lifting the guide rail to a predetermined position, it can not be easily moved when trying to move it on the already installed guide rail. In addition, there was a problem that the connection work could not be performed smoothly.

The present invention has been made to solve the above-mentioned problems. The purpose of the present invention is to eliminate the need for the operator to manually guide when the guide rail to be connected is hoisted and to have a predetermined height. When moving this guide rail that was hoisted up to a predetermined position on the hoistway wall,
It is an object of the present invention to provide a guide device for lifting a guide rail of an elevator, which enables the guide rail to be erected very easily and safely with almost no need for the work of guiding by a worker.

[0008]

In order to achieve the above-mentioned object, the present invention provides a substrate mountable on a frame that moves up and down in a hoistway, and is rotatably mounted on the upper part of the substrate.
A pulley device that rotatably supports a pulley that guides a rope that lifts a guide rail, and a guide roller device that rotatably supports a roller that is mounted on a substrate below the pulley device and that engages with the tooth surface of the guide rail that is lifted. It is composed of and.

[0009]

[Operation] When the guide rails are sequentially erected from the bottom on the hoistway wall, by attaching the lifting guide device to the work floor or gondola-like frame that hoists in the hoistway,
The winch for lifting the guide rail can be installed above the center of gravity of the guide rail for standing upright. Further, when the guide rail to be connected next is lifted, the pulley of the guide roller device is engaged with the tooth surface of the guide rail by rotating the pulley device toward the substrate side. The operator does not have to support it by hand,
Even if there is a difference in the relative speed between the guide roller and the frame, it is absorbed by the rotation of the roller, so that both the frame and the guide rail can be raised without any trouble. Furthermore, when positioning the hoisted guide rail above the guide rail that has already been erected, remove the rope from the pulley so that the guide rail is above the guide rail that has already been erected by the action of the center of gravity. Move to. Therefore, also in this case, the operator does not need to guide the guide rail.
