Abstract

PURPOSE:To eliminate the necessity of an upper template so as to reduce the cost of a centering device by leading a centering piano wire through a centering square hole and a retaining hole formed in the upper surface section of a return wheel beam so as to allow the wire to plumb from a predetermined portion on the upper surface section. CONSTITUTION:A centering piano wire 10 extending downward from a square hole 8 is drawn by a plumb-bob 11 connected to the lower end part of the piano wire 10 so as to plumb from a return wheel beam 1 down to the pit part of an elevator way 5. Further, the upper section of the piano wire is led through the square hole 8 and a retaining hole 9. This piano wire 10 is set after the return wheel beam 1 being centered and installed on a building beam 2 at a predetermined position through the intermediary of an attaching plate 1a by means of a bolt 4a and a nut 4b. By setting the return wheel beam in this way, the position of the piano wire 10 is automatically determined, and thereafter, left and right guide rails 7 are centered with reference to the piano wire 10. Then, the upper and lower end parts of the guide rails are fixed to the return wheel beam 1 and the bottom part 5b of an elevator way 5, and further, elevator hall equipments are fixed with reference to the piano wire.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is mainly used in small elevators such as home elevators, and is a centering piano wire that is used as a reference when installing guide rails and hall equipment. This invention relates to a centering device for installing an elevator that hangs down from the top of a hoistway.

[Prior Art] As a centering device for elevator installation, there is a device in which a centering piano wire, which is used as a reference when installing guide rails and hall equipment, is suspended from the top of a hoistway. As such an installation centering device, as shown in Japanese Utility Model Publication No. 59-43344, in order to hang the piano wire,
There was one in which a dedicated upper template was provided at the top of the hoistway, and the upper end of the piano wire was connected to the upper template.

[Intelligence to be Solved by the Invention] As mentioned above, in the conventional centering device for elevator installation, a special upper template is produced for hanging the piano wire for centering, and these templates are It is necessary to attach it to a predetermined position at the top of the hoistway, and there is a problem in that it requires a lot of cost to produce and attach the template.

This invention was made to solve the above-mentioned problems, and by eliminating a dedicated upper template, it is possible to install an elevator in which centering piano wire can be hung from the top of the hoistway at a low cost. The purpose of this invention is to provide a centering device for

[Means for Solving the Problems] The present invention provides a centering device for installing an elevator that includes a winding drum hoist and a return car beam installed at the top of a hoistway. A centering square hole and a centering stop hole are provided as a pair on the top surface, and a locking tool provided at the upper end of the centering piano wire is locked around the stop hole, and the piano wire is It is hung through the stopper hole and the square hole.

[Function] The elevator installation centering device according to the present invention utilizes a return wheel beam that is always provided in an elevator having a winding drum type hoist, and has a centering square hole and a centering hole in the upper surface of this beam. By providing the exit stop hole, the centering piano wire can be suspended from a predetermined position at the top of the hoistway even if the conventionally used upper template is eliminated.

[Embodiment] Hereinafter, an embodiment in which the present invention is applied to a small elevator such as a home elevator will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a return car beam with a mounting plate 1a fixed to a base plate 3 fixed to a construction site 2 with bolts 4a and nuts 4b, and the return car beam 1 is attached to the top 5a of a hoistway 50. Mounting frame 1 arranged and provided on the return vehicle beam L
A return wheel 6 is rotatably attached to c. Reference numerals 7 denote left and right guide rails, and the upper ends of these guide rails 7 are connected to the above-mentioned vehicle beam 1 with square root bolts 13a and nuts 13b.
The lower end portion is fixed to the bottom 5b of the hoistway 5 and stands upright on the bottom 5b.

Also, although not shown, it was installed at the bottom of the hoistway.
Similar to conventional elevators of this type, the car is guided by guide rails and moved up and down the hoistway by the drive of the hoisting machine. .

In this embodiment, a centering square hole 8 and a centering stop hole 9 are provided in the upper surface portion 1b of the above-mentioned return vehicle beam 1, which is also shown in FIG.
The left and right two pairs are the left.

They are formed at intervals B and G positions corresponding to the right guide rail 7. The centering piano wire IO extending below the square hole 8 is suspended from the return car beam 1 to the pit portion of the hoistway 50 by a plumb bob 11 connected to the lower end of the piano wire IO. Further, the upper part of the piano wire IO is passed through the square hole 8 and the stop hole 9, and a locking tool 12 such as a nut connected to the upper end of the piano wire 10 is inserted downwardly around the stop hole 9 in the upper surface part ib. The upper part of the piano wire 10 is supported by the upper surface part 1b of the turning beam l.

The setting work of the piano wire 10 is carried out by the construction industry 2.
Mounting plate 1. This is done after centering and installing with bolts 4a and nuts 4b through a.

By doing so, the position of the piano wire 10 is inevitably determined when the return wheel beam l is set. After that, the left and right guide rails 7 are centered using the piano 1i1110 as a reference, and the top of the guide rails 7 is aligned.

Turn the lower end part as described above and turn the vehicle beam 1. Bottom 5 of hoistway 5
b, and then fix the hall equipment using the piano wire as a reference.

[Effects of the Invention] As explained above, according to the present invention, in the centering device for installing an elevator including a drum hoist and a return car beam installed at the top of the hoistway, the above-mentioned A centering square hole and a centering stop hole are provided on the upper surface of the return wheel beam, and the piano wire for centering can be passed through these holes and suspended from a predetermined position on the upper surface, which is different from the conventional one. This function can be performed by the return beam without using an upper template exclusively for centering, and therefore the production cost of the template and the installation cost for setting it can be saved. This has the advantage that the piano wire can be suspended from the top of the hoistway at a low cost.
