Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator installation device that performs installation work without using a scaffold dedicated to installation or a movable workbench.

The installation method for elevators in medium and high-rise buildings was to temporarily install a mobile workbench in the hoistway.

This conventional installation method will be explained with reference to FIG.
In the figure, reference numeral 1 denotes a mounting base, which is fixed to the upper part of the hoistway, and an electric winch 2 is fixed to this mounting base 1.

Also, the guide rope 3 runs vertically from the mounting base 1 to the bottom of the hoistway.
is set up. Then, using the guide rope 3 as a guide, a mobile workbench 5 equipped with an emergency stop (not shown) connected to a speed governor 4 installed in the hoistway is assembled, and the mobile workbench 5 is moved using an electric winch 2. * Although illustrations are omitted, *Fixing and centering the crotch guide rail, installing landing parts, or piping and wiring work in the hoistway, and then moving the electric winch 2, mounting base 1, guide rope 3, etc. The workbench 5 and speed governor 4 are removed, and the car frame and counterweight are installed. However, this construction method required a lot of labor to temporarily install and remove the heavy electric winch 2 and mounting platform 1 above the hoistway, and was also highly dangerous.

Furthermore, since the movable workbench 5 needs to be sized to match the cross-sectional shape of the hoistway, it is necessary to prepare many types of movable workbench 5, which requires a large amount of expense to store and manufacture. Furthermore, after installing the landing parts, piping and wiring to the hoistway, the mobile workbench 5,
The guide rope 3 and speed governor 4 had to be removed, which required a great deal of effort, resulting in a drawback that it required a lot of cost and time. This invention solves the above-mentioned drawbacks by installing an electric winch at the bottom of the hoistway.*
It is an object of the present invention to provide an elevator installation device that can be easily installed using a crotch elevator car frame.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, the same reference numerals as in FIG. top 6
2 is an electric winch fixed to the lower part of the hoistway 6, and 2a is a wire robe of this,
Reference numeral 9 denotes a workbench with a car movably engaged with the guide rail 7, 10 a main machine stand installed on the top 6a, and 11 a workbench installed on this with the brake 11a released. A pulley device consisting of an installed hoisting machine, 11b a pulley consisting of a drive network pulley of the installed hoisting machine, 12 a well-known deflection wheel, 13 an operation button temporarily installed on the workbench 9 and connected to the winch 2,
Reference numeral 14 denotes an emergency stop device that is provided on the workbench 9 and performs a braking operation according to the operation of the speed governor 4.

That is, the wire robe 2a is wound around a pulley 11b and connected to the workbench 9, and only the upper and lower ends are fixed to the hoistway 6, and the workbench 9 is attached to a temporarily erected guide rail 7.
will be guided.

The winch 2 is controlled by a worker operating the operating button 13 on the workbench 9 to raise and lower the workbench 9. With this, the centering and fixing work of the middle part of the guide rail 7 is performed, and then, although not shown in the drawings,
Work such as installation of landing parts, installation of equipment in the hoistway 6, piping, wiring, etc. is performed. So. Then, the work platform 9 is fixed by operating the emergency stop device 14, a counterweight (not shown) is assembled at the bottom of the hoistway 6, and the pulley device 11 is fixed.
．． That is, the brake 11a of the permanent hoist is operated to apply the permanent wire lobe to the drive net car, and the work platform 9, that is, the permanent car and the counterweight are connected. In this way, since the guide rails, hoisting machine, car, etc. for the permanent installation are used as installation equipment, the preparation, temporary installation, and removal of temporary equipment exclusively for installation can be omitted, and the elevator can be easily installed. I can do it. Moreover, the trouble of installing and removing the heavy winch 2 at the top 6a of the hoistway 6 can be omitted, and the efficiency of the installation work can be improved. It should be noted that even if the pulley device 11 in this embodiment is composed of a temporarily installed appropriate pulley, substantially the same effect as in the embodiments shown in FIGS. 2 and 3 can be obtained.

As explained above, in this invention, only the upper and lower ends of the guide rails for permanent installation connected in series are fixed and temporarily erected in the hoistway, and a work platform consisting of a car for permanent installation is moved on this. The wire lobes of a winch fixed at the bottom of the hoistway are connected to the work platform via a pulley device installed at the top of the hoistway, and the winch is controlled to raise and lower the work platform for various installations. It is something that performs work.

As a result, the main installation equipment is used for the main parts of the installation equipment such as the guide rail and workbench, so it is possible to omit the preparation, temporary installation and removal of equipment dedicated to installation, and it is also possible to easily install the winch. To realize an elevator installation device which can be temporarily installed and removed, which is simple, allows efficient work, and saves costs.
