DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator installation template provided for covering an opening formed in a machine room floor above a hoistway and used for elevator installation.

[0002]

2. Description of the Related Art FIG. 2 is a longitudinal sectional view showing a conventional installation template provided on a machine room floor above a hoistway, and FIG. 3 is a plan view showing the installation template of FIG. 2 and its periphery. . On the upper part of the hoistway 1 of the elevator shown in FIG.
A machine room 2 in which machine room equipment such as a traction machine and a machine beam is installed is provided, and an opening 4 is formed in a floor 3 of the machine room 2. In the hoistway 1, a piano wire 5 for centering reference of a not-shown hoistway installation device installed in the hoistway 1 is stretched. On both sides of the opening 4, as shown in FIG.
Suspension holes 10 and 11 for suspending the suspension 9 respectively are provided. A rope insertion hole 20 through which a governor rope (not shown) is inserted is formed near the suspension hole 10.

A conventional installation template 6 provided in such an elevator is installed on the floor 3 of the machine room 2 so as to cover the opening 4. As shown in FIG. 3, the installation template 6 has a generally square shape corresponding to the shape of the opening 4, and includes three divided portions 6a integrally connected by bolts (not shown). 6b and 6c. A pair of insertion holes 7 through which the piano wire 5 is inserted are formed in the central divided portion 6b. Further, each part of the hanging holes 10 and 11 is a plate 12,
13. Each plate 12, 1
3 is provided with insertion holes 14 and 15 through which the centering piano wires of the car guide rails 8 and 9 are inserted.

[0004] In such a conventional installation template 6, first, the machine room equipment described above is carried into the machine room 2 from the hoistway 1 through the opening 4, and then installed on the floor 3 of the machine room 2. The template 6 is temporarily placed, and the insertion hole 7 is
After the positioning of the installation template 6 is performed by adjusting the position of the installation template 6, the installation template 6 is fixed to the floor 3.
Next, the center line 16 of the installation template 6 is centered on the basis of the insertion hole 7, and the plates 12, 13 are positioned on the basis of the center line 16 and fixed to the floor 3. Then, one of the guide rails 8 for the car is centered and fixed on the basis of a piano wire (not shown) which is inserted through the insertion hole 14 of the one plate 12 and hangs down in the hoistway 1, and is similarly fixed. Then, the guide rail 9 for the other car is centered and fixed with respect to a piano wire (not shown) which is inserted into the insertion hole 15 of the other plate 13 and hangs down in the hoistway 1. In addition, a straight line 17 connecting the other insertion holes 14 and 15 is drawn, and reference lines 18 and 19 for installing a governor machine (not shown) are drawn based on the straight line 17 and the center line 16. The governor machine is positioned with reference to 18 and 19.

[0005]

By the way, in the above-mentioned conventional installation template 6, the guide rails 8 for the car,
When centering 9, an operation of centering the center line 16 with reference to the insertion hole 7 of the piano wire 5 and an operation of positioning the plates 12 and 13 with reference to the center line 16 are required. Therefore, there is a problem that it takes much time to center the guide rails 8 and 9 for the car. Further, when centering a governor machine (not shown), the work of drawing the center line 16 and the straight line 17 and the reference lines 18 and 1 are also performed.
Since the work of drawing 9 is required, there is a problem that it takes much time to center the governor machine.

The present invention has been made in view of such a situation in the prior art, and an object of the present invention is to provide an elevator installation template capable of quickly aligning a guide rail and a governor machine. To provide.

[0007]

In order to achieve this object, the present invention is directed to a plurality of shafts provided to cover an opening formed in a machine room floor above a hoistway, and through which a centering reference piano wire is inserted. In an elevator installation template having holes of
A first hole located above a guide rail erected in the hoistway, and a second hole disposed near the first hole and through which a centering reference piano wire of the guide rail is inserted. A hole, a centering edge for engaging with a predetermined portion of the governor machine installed in the machine room, and a third hole through which a governor rope to be wound around the governor machine is inserted. .

[0008]

Since the present invention is constructed as described above, first, a machine room equipment such as a control panel, a traction machine, a governor machine, and a machine beam is carried into the machine room from the hoistway through the opening, and then the mounting mold is mounted. Place the plate on the machine room floor,
After performing the positioning by moving the installation template in the left-right and front-rear directions so that the second hole matches the reference line of the building,
While suspending the guide rail through the first hole,
The centering reference piano wire is inserted into the second hole and stretched in the hoistway, and the guide rail is centered on the basis of the piano wire. This eliminates the need for the centering of the guide rail, the work of centering the center line of the template with reference to the insertion hole of the piano wire, and the work of positioning and arranging another plate. Therefore, the guide rail can be centered quickly.

Further, as described above, after the installation template is arranged on the floor of the machine room so that the second hole matches the reference line of the building, the installation template is provided on the installation template. By engaging a predetermined portion of the governor machine with the centering edge of the governor machine, the governor machine is arranged at a predetermined position, that is, the governor machine is positioned. Thus, when the governor machine is centered, there is no special need to draw a reference line, so that the governor machine can be quickly centered.
