This effect is particularly noticeable in high-speed elevators installed in high-rise buildings, which require extremely strict installation precision. Moreover, since the centering and positioning work is performed in a dimly lit and narrow hoistway, the work is dangerous, time consuming, and troublesome. For this reason, various guide rail centering devices have already been proposed in order to simplify the centering and positioning work as much as possible. A typical example is the device shown in Japanese Utility Model Publication No. 57-2883.

The guide rail centering device is shown in FIG.

In the figure, reference numeral 1 denotes an elevator hoistway, and left and right guide rails 3 are attached to the inner wall of the hoistway through rail brackets 2 over the entire height, respectively, in a temporarily tightened state. In order to center and position the left and right guide rails 3, templates (not shown) are set at the top and bottom of the hoistway 1, and stretched between the upper and lower templates to center a piano wire, etc. The guide rail centering device 6 is installed between the left and right guide rails 3 while the guide rail centering device 6 is installed vertically at predetermined reference positions corresponding to the upright positions of the left and right guide rails 3 in the hoistway 1. do.

This guide rail centering device 6 has ruler plates 8 fixed to both left and right ends of a base body 7. One side of the left and right ruler plates 8 has a reference surface 8a that joins to the tip and -side surfaces of the guide rails 3 in order to regulate the mutual spacing and inclination of the left and right guide rails 3, and the other side has a notch recess 8b and an index line 8C that align with the centering reference line 5.

Furthermore, gripping tools 9 are provided for attaching and holding the left and right ruler plates 8 to the left and right guide rails 3.

That is, the ruler plates 8 at both left and right ends of the guide rail centering device 6
The left and right guide rails 3 with the reference surfaces 8a and 8b temporarily tightened
The left and right ruler plates 8 are attached to the left and right guide rails 3 by locking and tightening the gripping tool 9 on the flange-side edge of the guide rail 3 in this state. The installation will hold. This holds the left and right guide rails 3 at a predetermined distance from each other, regulates the inclination, and integrates both.

In this state, move and adjust the left and right guide rails 3 together with the centering device 6, and make fine adjustments so that the centering reference line 5 enters the notch recess 8C of the left and right ruler plate 8 and matches the index line 8d. do. This means that the left and right guide rails 3 have been centered in the predetermined positions, and the left and right guide rails 3 are completely tightened and fixed to the rail bracket 2 to complete the installation work. Thereafter, the centering device 6 loosens and removes the gripping tools 9 at both left and right ends.

Further, as an example of centering the left and right guide rails 3 one side at a time, there is a centering device 10 shown in FIG. 7. This is a U-shaped block-shaped gripper 1 that is applied to the guide rail 3.
Has 1. This gripping tool 11 is held attached to the guide rail 3 by tightening the fixing bolt 12. This gripping tool 11 has two reference surfaces 11a that are joined to the side surface and the top surface of the guide rail 3. Further, a ruler plate 13 extending to one side is fixedly attached to the upper surface of the gripping tool 11. The ruler plate 13 is provided with four notches 13a at the tip thereof to receive the centering reference line 5, and three index lines 13b displayed on the upper surface of the periphery of the recess 13a.

Even in this case, move and adjust the temporarily tightened guide rail 3 so that the centering reference line 5 enters the recesses 13a on both sides of the ruler plate 13 on the gripper 11, and in that state, move the guide rail 3. The guide rail 3 is then centered by further fine adjustment until the centering reference line 5 is aligned with the extension of each index line 13b within the four parts 13a.

(Problem to be Solved by the Invention) By the way, in the conventional elevator equipment centering device as described above, the recess 8b of the ruler plate 8 or 13.

The index line 8c of the centering reference line 5 is located within the centering reference line 13a.

The centering accuracy of the guide rail 3 is influenced by the degree of coincidence with respect to the guide rail 13b. For this reason, in the case of high-speed elevators that require high precision, the centering reference line 5 is
Although it is necessary to make fine adjustments so that the four parts 8a completely match the index lines 8b, there is a problem in that this work requires a lot of time and nerves. In other words, since the inside of the elevator hoistway 1 is under construction, there is not enough lighting and the environment is dim, so the centering reference line 5 with respect to the index lines 8c and 13b
It is extremely difficult and difficult to visually determine the degree of agreement between the two, and operators must rely on their intuition. Moreover, many of the workers are elderly and have poor eyesight. For this reason, the centering reference line 5 within the four parts 8b and 13a is the index line 8b.

Fine adjustment of the centering so as to accurately match 12b is very troublesome and requires a lot of time and careful attention.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a highly accurate elevator equipment centering device that allows the centering of elevator equipment such as guide rails to be performed very simply, accurately, and efficiently in a short period of time. purpose.

First, centering reference lines 5 made of conductive material such as piano wire are vertically provided at predetermined reference positions corresponding to the upright positions of the guide rails 1, as in the conventional art.

On the other hand, as the guide rail centering device 20, a U-shaped block-shaped gripping tool 21 abuts against the guide rail 3 and is held in place by tightening a fixing bolt 22.

This gripping tool 21 has two reference surfaces 21a that are joined to the side surface and the top surface of the guide rail 3. Also, this gripping tool 2
1 has a pair of upper and lower extending plate portions 21b and 21c extending horizontally on the opposite side from the fixing bolt 22. Insulating plates 23 and 24 are attached to the opposing surfaces of the upper and lower extending plate portions 21b and 21c by bolts and nuts 25, respectively, and ruler plates 27 and 24 are attached to these insulating plates 23 and 24 by adhesives, screws, etc., respectively. 28 is attached. The pair of upper and lower ruler plates 27 and 28 are each made of a conductive material, but are electrically insulated (separated) from each other by the insulating plates 23 and 24. This upper and lower ruler board 27.2
Each of the numerals 8 has a rectangular shape, and approximately half of each of them protrudes rearward from the extending plate portions 21b and 21c of the gripping tool 21.

V-shaped notches 27a and 28a are formed in the central fixed position portions of the rearwardly protruding tips of the upper and lower ruler plates 27 and 28 to align with the centering reference line 5.

On the other hand, the gripping tool 21 includes the upper and lower ruler plates 27.2.
When the centering reference line 5 enters and comes into contact with the notches 27a and 28B of 8, an electric closed circuit is formed and an indicator 30 is provided that lights up to indicate that the guide rail 3 has been centered. There is. This indicator 30 uses a lamp (e.g. a light emitting diode) 31, and this lamp 31 is assembled from the upper surface of the upper extending plate portion 21b of the gripper 21, and this power source (dry cell etc.) 32 is connected to the gripper 21. It is attached inside the tool 21. The anode side of this power supply 32 is electrically connected! !
The other terminal of the lamp 31 is connected to the upper ruler plate 27 via the electric wire 34, and the lower ruler plate 28 is connected to the cathode side of the power source 32 via the electric wire 35. It is connected to the. The electric circuit 4o shown in FIG. 4 is now configured, and the upper and lower ruler plates 27, 28 and the centering reference line 5 are used as a kind of opening/closing switch.

Thus, by using the centering device 20 configured as described above, the hoistway 2
To center the guide rail 3 that has been temporarily erected in the interior, first, as in the past, centering reference lines 5 are vertically set at predetermined reference positions corresponding to both sides of the erected position of the guide rail 1. Meanwhile, the gripping tool 21 is attached to the guide rail 3 by tightening the fixing bolt 22.

In this state, the guide rail 3 is moved and adjusted together with the gripper 21, and the extension plate portion 21b of the gripper 21 is moved.

．． When the centering reference line 5 enters and makes contact with the notch 27 a s 28 a of 28, the upper and lower ruler plates 27 and 28 become electrically conductive through the reference line 5, and the electric circuit 4o of the display 30 becomes electrically conductive. In the closed state, the lamp 31 lights up. At this point, the guide rail 3 has been accurately centered. Therefore, when the worker visually confirms that the lamp is lit, he stops adjusting the movement at that point and fully tightens the guide rail 3 to the rail bracket 2.

As described above, the guide rail 3 with respect to the centering reference line 5
Since the correctness or failure of centering can be easily confirmed at a glance by lighting the lamp 31, centering work can be performed easily and accurately even in the dimly lit hoistway 1. In other words, the inefficient work of placing the centering reference line 5 into a small recess on the ruler plate and matching it with the index line, which is very difficult to see, requires nerves, and is difficult to distinguish, as in the past, is no longer necessary. rail 3
The centering work can be performed very simply, accurately, and efficiently in a short time.

In the above embodiment, an example was shown in which centering of the guide rails 3 is carried out on one side, but the present invention can also be applied to a case where the left and right guide rails 3 are simultaneously centered as shown in FIG. In this case, two sets of the centering devices 20 described above are used, and these are fixed to both left and right ends of the base body 50, respectively. The left and right gripping tools 21, 21 are mounted and held on the left and right guide rails 3.3, respectively. This makes it possible to efficiently adjust the centering of the respective guide rails 3, 3 while correctly regulating the mutual spacing and inclination of the left and right guide rails 3, 3.

Further, in the above embodiment, an example was shown in which the present invention was applied to the centering work of the guide rail 3, but it can also be applied in substantially the same way to the centering work when installing elevator equipment such as doorway sills.
