Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for installing an entrance / exit part of an elevator, and more particularly to a device for installing an entrance / exit part of an elevator suitable for installing an entrance / exit part such as a sill arranged at a landing of an elevator.

[0002]

2. Description of the Related Art As a conventional installation device for an entrance / exit of an elevator, a device disclosed in, for example, Japanese Patent Application Laid-Open No. 61-217485 is known, which is shown in FIG. The figure is a side view showing a state during installation work of an entrance / exit component of an elevator. A guide bar 2 is erected on a car floor 1, and a first gripping portion is movably mounted on the guide bar 2 in its axial direction. Three
The second grip 4 is attached, the first grip 3 holds the sill 5 for guiding the hall door, and the second grip 4 holds the pocket 6 for holding the hall door.

Sill 5 and pocket 6 which are doorway parts
To install on the side of the building, hold the sill 5 with the first grip 3 and hold the pocket 6 with the second grip 4, and move the car floor 1 up and down to the floor where the doorway parts are installed and stop. After that, the first gripping part 3 is moved along the guide bar 2 to adjust the height of the sill 5 to the hoistway wall 7 of the installation floor.
7 is made to coincide with the reference position measured using the building reference black ink 8 as a reference, and then the brackets 9 and 10 are fixed to the hoistway wall 7 as shown in the lower part of FIG. 7, and the sill 5 is attached and fixed thereto. Then, the car floor 1 is moved to the vicinity of the height position of the sill 5 where the fixing is completed and stopped. In this state,
The height position from the sill 5 is measured using a scale or the like to determine the position of the pocket 6, and the pocket 6 is moved along with the second grip portion 4 along the guide bar 2 to the determined predetermined position, and the predetermined position is determined. At the position, the pocket 6 was fixed to the hoistway wall 7 via the bracket 11.

[0004]

However, in the conventional installation of the entrance / exit parts of the elevator, as described above, when the sill 5 and the pocket 6 are installed, the car is frequently moved up and down, or a scale or the like is used to determine a predetermined distance from the reference line. Since the work to measure the installation position of was required, the efficiency of the installation work was poor.

It is an object of the present invention to provide a device for installing elevator doorway parts, which enables highly accurate and efficient installation of a sill and a pocket.

[0006]

In order to achieve the above object, the present invention relates to an elevator entrance / exit part installation apparatus for installing an entrance / exit part arranged at a landing of an elevator using a car. A first gripping device capable of moving in the ascending / descending direction of the car, a second gripping device capable of gripping different entrance / exit components and movable in the ascending / descending direction of the car, and the first gripping device; A driving means for interlocking the second gripping devices with each other at a predetermined interval is provided.

[0007]

As described above, the elevator entrance / exit installation device according to the present invention is configured so that, for example, the sill is held by the first gripping device and the pocket is held by the second gripping device while the car is held at the predetermined floor. When the position of the sill held by the first holding device is made to coincide with the reference position of the hoistway wall by raising and lowering to the landing position and stopping, the second holding device is raised by the driving means, a predetermined interval is maintained. Since the first gripping device connected by the above can be raised and held at a predetermined position, the sill and the pocket can be fixed to the hoistway wall in that state. In this way, the car can be raised and lowered basically only once, and it is no longer necessary to raise and lower it as frequently as in the past, and the position of the pocket does not need to be measured with a scale, etc., and installation of entrance and exit parts such as sill and pocket Can be performed with high accuracy and efficiency.
