Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for centering a guide rail for a counterweight of an elevator.

[Conventional technology]

When installing an elevator, it is necessary to attach the car guide rail and the counterweight guide rail to the wall of the hoistway in a centered manner.

Previously proposed elevator installation methods (Japanese Patent Laid-Open No. 55
48182), this centering work is performed using piano wire. That is, as shown in Figure 2,
First, in the machine room 13 provided on the top floor of the building, the center of the first car and the center of the guide rail for the car counterbalance weight are set, and centering with respect to the machine room 13 is performed.

Next, piano wire, which is used as a reference for setting the guide rail for the passenger seat and counterweight, is stretched from the machine room 13 toward the bottom of the hoistway. After this work, the car guide rail 7 is connected and lifted up with a winch, and its upper end is fixed to the floorboard of the machine room 13 with the piano wire as a reference.

In this way, the lower end of the car guide rail 7 whose upper end is fixed to the floorboard of the machine room 13.

Center the seat based on the piano wire within the range where the seat is assembled. The portion of the car guide rail 7 that has been centered is fixed to the wall surface of the hoistway in a centered state via the guide rail mounting bracket 5.

Through this work, after centering and fixing the lower end of the car guide rail 7 to the hoistway wall surface, the hoisting machine 8 is placed in the machine room 13.
．． Install the machine room related quantities such as the control panel 9, and connect and configure the low-speed motion diversion circuit.

Next, the car floorboard 1. Then, the counterweight 10 is carried into the hoistway and assembled, and the rope 11 is passed over.

The operating cable 12 is stretched from the machine room 13 to the car floor plate 1, and a worker gets on the car floor plate 1. In this state, the car floor plate 1 is driven upward at a low speed. A worker performs centering of the fifth car guide rail 7 at predetermined intervals using the piano wire as a reference, and fixes the guide rail to the hoistway wall via the guide rail mounting bracket 5. The car floor plate 1 is driven at low speed over the entire area of the hoistway, and the centering work of the car guide rail 7 over the entire area of the hoistway is completed.

After the centering work of the guide rail 7 for the car is completed, the first car floor plate 1 is lowered to the lower surface of the hoistway, and the work for centering the guide rail 4 for the counterweight is performed.

Using piano wire, which is used as a reference for setting the counterweight guide rail 4 stretched from the machine room 13 to the lower surface of the hoistway, center the counterweight guide rail 4 in exactly the same way. will be carried out.

[Problem that the invention seeks to solve]

In the above-mentioned conventionally proposed elevator installation method, even when centering the guide rail for the counterweight, it is necessary to stretch a reference piano wire and perform centering using this piano wire. The work of stringing the piano wire was not easy, and as a result, the work of installing the elevator was complicated.

An object of the present invention is to provide a simple method for installing a guide rail for an elevator counterweight.

[Means for solving problems]

The above purpose is to grip the two counterweight guide rails with a gripping tool that simultaneously regulates the mutual spacing and degree of facing, and then aligns the gripping tool with a reference plane formed on the floorboard of the car to center the guide rails. and then the guide rail attachment is achieved by fixing with brackets.

[Effect]

In the present invention, after centering the car guide rail, the reference plane formed on the outer frame of the car floor plate is always at a constant distance from the position of the car guide rail, so there are two After gripping the counterbalance weight guide rail with a gripping tool that simultaneously regulates the mutual spacing and degree of facing of the counterbalance weight guide rails, the guide rail can be moved to a predetermined position without twisting, i.e., by moving it in line with the reference plane. It can be fixed upright with the facing degree corrected.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

In this figure, 1 is an elevator car floor plate, 15 is an outer frame attached to the periphery of the car floor plate 1, 2, 2
′ is a reference surface constructed as a precision finished surface on the outer surface of the outer frame 15 in accordance with a predetermined distance that is the mutual spacing between the two counterweight guide rails 4 and 4′; , 4' and guide rail mounting are gripping tools for installing the bracket 5.5'.

This gripping tool 3 has metal fittings 3a, 3a' that grip the sliding portions of the guide rails 4, 4' after insertion, and a presser plate 3b that holds down the guide rails 4, 4'.

3b', handles 3c, 3c' that completely fasten the holding plates 3b, 3b', stoppers 38, 38' that regulate the mutual spacing between the guide rails 4°4', and reference surfaces 2, 2'. It is composed of ruler surfaces 3d and 3d' that are arranged symmetrically on the left and right.

In this invention, before the centering work of the counterweight guide rails 4° 4', the centering work of the car guide rails 7, 7' is performed in the same manner as in the previously proposed method described above. .

Therefore, with the car guide rail 7.7' centered via the guide rail mounting bracket 5.5',
It is fixed to the hoistway wall surface 6.

For this purpose, a reference surface 2.2' formed on the outer frame 15 is
No matter where the car floor plate 1 is located in the hoistway,
It is always at a constant distance from the car guide rail 7.7'.

When centering the counterweight guide rails 4, 4', the car floor plate 1 is lowered to the lowest position in the hoistway. In this state, the counterweight guide rail 4.4
' is fixed at its upper end at a preset reference position in the machine room 13.

A working tool gets on the car floor plate 1, and the car floor plate 1 is driven upward at a low speed. The worker should use the metal fitting 3a to hold the gripping tool 3.
, 3a', a stopper 3e for regulating the sliding portion of the counterweight guide rails 4, 4', and for regulating the mutual distance between the two guide rails 4, 4'.

After inserting up to 3e', firmly tighten the handles 3c and 3c' via the holding plates 3b and 3b'.
The counterweight guide rails 4, 4' and the gripping tool 3 are firmly connected. Ruler surfaces 3b, 3b' of the connected gripping tools
By aligning 2 and 2' with 2 and 2', centering of the counterweight guide rails 4 and 4' is completed, and the guide rails are raised via the guide rail mounting brackets 5 and 5'. The bracket 1 is fixed to the wall 6 of the section.

The centering work of the counterweight guide rails 4, 4' is performed in this way over the entire area of the hoistway, and the counterweight guide rails 4, 4' are installed on the hoistway wall surface 6.

By connecting the counterweight guide rails 4, 4' and the gripping tool 3, the mutual spacing and facing position of the two guide rails 4, 4' can be easily regulated at the same time.
' is at the reference position with respect to the car guide rail 7.7', so the reference plane 2°2' and the ruler surfaces 3d, 3 of the gripping tool 3
By aligning d', the counterweight guide rail can be efficiently placed in the predetermined position, and the mutually opposing bottoms of the two counterweight guide rails can be installed with high precision without twisting. can be done.

〔Effect of the invention〕

According to the present invention, centering and installation of a counterweight guide rail can be performed with high precision and efficiency without stretching piano wire in the hoistway.
