Is centered and fixed to the hoistway wall on the piano wire 1b side with respect to the other piano wire 1b, thereby forming a guide rail 5 standing upright over the entire length of the hoistway 3.

FIG. 12 is a flow chart showing the procedure of the work for vertically setting the guide rails 4, 5 in the hoistway 3. As shown in the figure, first, in step S1, a pair of piano wires 1a and 1b are hung from the machine room 2 into the hoistway 3 with reference to a predetermined position of the building. Next, step S2

In step S5, the upper end of the guide rail 4 (that is, the upper end of the rail member 4a) is held on the machine room floor 2a. Similarly, with respect to the rail member of the guide rail 5, by repeating the lifting operation and the connecting operation, the guide rail 5 extending over the entire length of the hoistway 3 is formed by an integrated product of a plurality of rail members 5a, 5b, .... The upper end of the guide rail 5 is held by the machine room floor 2a. Next, in step S6, the car frame 7 and the work floor 8 (see FIG. 1) slidably engaged with the lowermost rail members of the guide rails 4 and 5.
1 and 13) by driving the hoisting machine in the machine room 2, and in step S7, an operator on the work floor 8 centers and lifts each rail member of the guide rails 4 and 5. Secure to the road wall.

In performing such centering work, conventionally, a centering device 9 as shown in the perspective view of FIG. 13 and the plan view of FIG. 14 is used.

That is, the centering device 9 is used for the work floor 8
A bar-shaped base 10 installed on the top and extending in the horizontal direction, a gripping device 11 and a reference part 12 provided at one end of the base 10, and a gripping device 1 provided at the other end of the base 10.
3 and the reference unit 14 are generally configured. Here, the gripping device 11 includes a fixing member 11a that sandwiches a rail member (for example, the rail member 4a) that constitutes the guide rail 4.
And the movable member 11b and these members 11a and 11b
It is composed of a bolt 11c for tightening the space and gripping the rail member. The reference portion 12 has a reference surface 12a in the X direction (see FIG. 14) formed at one end thereof, and a reference line 12b in the Y direction (direction orthogonal to the X direction in the horizontal plane) on the upper surface thereof. Is attached. Similarly, the gripping device 13 includes a fixed member 13a and a movable member 13b that sandwich a rail member (for example, a rail member 5a) that constitutes the guide rail 5, and a bolt that clamps between the both members 13a and 13b to grip the rail member. 13c, the reference portion 14 has an X-direction reference surface 14a formed at one end thereof, and the Y-direction reference line 1 is formed on the upper surface thereof.
4b is attached.

Next, the centering and fixing work of the rail members 4a and 5a performed by using the centering device 9 having the above-mentioned structure will be described.

First, the guide portion 41a of the rail member 4a is grasped by the grasping device 11, and the fixing portion 42a of the rail member 4a is attached to the rail clip 15a in this state, whereby the rail side bracket 15b and the wall side bracket 15c. The rail member 4a is temporarily fixed to the hoistway wall 20 via. The rail clip 15a is integrated with the rail side bracket 15b, the rail side bracket 15b is bolted to the wall side bracket 15c, and the wall side bracket 15c is bolted to the hoistway wall 20. . Similarly, the guide portion 51a of the rail member 5a is grasped by the grasping device 13, and the fixing portion 52a of the rail member 5a is attached to the rail clip 16a in this state, so that the rail side bracket 16b and the wall side bracket 16c are interposed. Then, the rail member 5a is temporarily fixed to the hoistway wall 21.

Next, the operator moves the rail member 4a in the X direction while hitting the rail side bracket 15b with a hammer to set the distance from the piano wire 1a to the reference surface 12a to a predetermined dimension, and The rail member 4a is moved in the Y direction while hitting the wall-side bracket 15c with a hammer, and the distance from the piano wire 1a to the reference line 12b is set to a predetermined dimension. Similarly, the operator moves the rail member 5a in the X direction while striking the rail-side bracket 16b with a hammer to set the distance from the piano wire 1b to the reference surface 14a to a predetermined dimension, and with a hammer. The rail member 5a is moved in the Y direction while striking the wall-side bracket 16c so that the distance from the piano wire 1b to the reference line 14b is set to a predetermined dimension.

When the centering of the rail members 4a and 5a is completed in this way, the rail members 4a and 5a are respectively moved up and down by fully fastening the fixing bolts of the rail side brackets 15b and 16b and the wall side brackets 15c and 16c. It will be permanently fixed to the walls 20 and 21.

[0011]

By the way, in the centering and fixing work of the elevator guide rail performed by using the above-mentioned conventional centering device 9, each rail member is attached to the hoistway wall 2.
The rail side bracket 15 is temporarily fixed to 0 and 21.
While the b, 16b and the wall side brackets 15c, 16c are hit with a hammer or the like, a position adjustment work for setting the distance between the reference piano wire and the rail member to a predetermined dimension must be performed. Since it takes a lot of time, there is a problem that work efficiency is poor.

In principle, the hoistway walls 20 and 21 facing each other must be finished in a state where their parallelism is maintained, but in reality, a part of the hoistway walls is slightly inclined with respect to the vertical plane. In many cases, the parallelism between the wall-side brackets 15c and 16c attached to the hoistway walls 20 and 21 having poor parallelism also deteriorates. A pair of rail members (for example, rail members 4a and 5) temporarily fixed to the same height via the rail-side brackets 15b and 16b.
a) The two are twisted with each other. Then, in order to attach the centering device 9 to the pair of rail members having such a twisted relationship, the guide portion (for example, the guide portion 41) thereof is attached.
a, 51a) is gripped by the gripping devices 11 and 13, there is a possibility that the guide portions are bent due to excessive bending stress, and in that case, the centering and fixing are completed and the gripping device 11 is terminated. Since the bending of the guide portion of the rail member returns to its original position when the rails 13 and 13 are removed, the centering position is misaligned and the centering accuracy is inevitably deteriorated.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide an elevator guide rail centering device capable of accurately centering the guide rail in a short time. .

[0014]

Further, on the gauge member 35, the gauge member 35
A bubble tube 50 for confirming the horizontality of the reference members 41a and 41b is fixed.

Next, the centering work of the elevator guide rail performed using the above-mentioned centering device will be described.

Now, assuming that the rail members 4a and 5a are to be centered, first, on the handrail 51 of the work floor 8 installed in a car frame (not shown), as shown in FIG. On the other hand, the tension holding device 30 in which the extension members 33a and 33b are fully retracted and shortened is attached, but at this time, the rail gripping devices 451 and 452 are in an open state in which the rail members 4a and 5a are not yet clamped.
Then, after moving the car frame so that the rail gripping devices 451 and 452 come to the predetermined positions where the rail members 4a and 5a are installed and fixed, the jack bolts 31a are attached to the hoistway wall 20 as shown in FIG. Extension member 33a until abutting
Is made to protrude from the base member 300, the extension member 33a is made non-slideable by the rotation operation of the lever 32a, and the extension member 33b is made to protrude from the base member 300 until the jack bolt 31b comes into contact with the hoistway wall 21. The extension member 33b cannot be slid by rotating the lever 32b. As a result, the base member 300 and the extension members 33a and 33b are integrated with each other to form the hoistway wall 2.
Since it is held between 0 and 21, by rotating the jack bolts 31a and 31b so as to project from the extension members 33a and 33b in this state, the hoistway walls 20 and 21
The tip ends of the jack bolts 31a and 31b are strongly pressed against and the tie holding device 30 is securely fixed between the hoistway walls 20 and 21 by its own traction force.

After that, the procedure as shown in FIGS.
Rail member 4a by rail gripping devices 451 and 452,
5a is clamped and held, and via the tension holding device 30 held by the tension force between the hoistway walls 20 and 21,
These rail members 4a and 5a are indirectly connected to the hoistway wall 2
It is fixed to 0 and 21. That is, when the rail gripping device 451 is described, at first, as shown by a chain line in FIG. 5, the pair of rear surface contact portions 39a are in an open state, and the rear surface contact portions 39a are indicated by arrows in FIG. 60
Direction, and then pulling the lever portion of the tension clamp 44a to move each back contact portion 39a in the direction of arrow 61 in FIG. 6, the rail member 4a also pulled in the direction of arrow 61 becomes the reference member 41a. Press against.
Next, by rotating the pinching screw 49a and moving it in the direction of the arrow 62 in FIG. 7, the rail member 4a is pinched between the guide surface contact portion 40a and the reference member 41a, so that the rail member 4a can As shown in FIG.
It is in a state of being pinched and held by a, the guide surface contact portion 40a, and the reference member 41a. The rail member 5a is also clamped and held by the rail gripping device 452 in the same manner.

The rail members 4a and 5a thus held by the rail holding devices 451 and 452 are stretched and held by the holding device 3.
When a series of work for indirectly fixing to the hoistway walls 20 and 21 via 0 is completed, these rail members 4a and 5a
Perform position adjustment work for centering.

In the position adjusting work, first, the adjusting screw portion 37 of the first position adjusting device 42 is rotated to displace the slide member 38 in the left-right direction (X direction) of FIGS. 1 and 3. A gauge member 35 is connected to the slide member 38, and rail gripping devices 451 and 452 and reference members 41a and 4 provided on the gauge member 35 are connected.
Since the rail members 4a and 5a are clamped and held on the rail member 1b, when the adjusting screw portion 37 is rotated to displace the slide member 38, the rail members 4a and 5a are also displaced. The X dimension on the side of the hoistway wall 20 shown (the distance between the piano wire 1a and the reference plate 43a) and the hoistway wall 21
The position can be easily adjusted so that the X dimension on the side (the distance between the piano wire 1b and the reference plate 43b) becomes equal.

Next, the second position adjusting device 481,
By turning the adjusting screw portions 48a and 48b of 482 and appropriately rotating the gauge member 35 with respect to the slide member 38 in the clockwise direction or the counterclockwise direction in the horizontal plane,
The rail member 4a held by the gauge member 35,
5a is displaced in the vertical direction (Y direction) of FIGS. Therefore, the Y dimension on the side of the hoistway wall 20 shown in FIG. 9 (piano wire 1a and marking wire 43c attached to the reference plate 43a)
And the Y dimension on the side of the hoistway wall 21 (piano wire 1b).
And the marking line 43d attached to the reference plate 43b) can be easily adjusted so that both are within the allowable value, and the rail members 4a and 5a can be held in a state of being centered in the Y direction. However, since the adjustment amounts of the second position adjusting devices 481 and 482 are not the same, the rotation of the gauge member 35 in the horizontal plane may cause a slight deviation in the previously adjusted setting position in the X direction. , Y-direction position adjustment is performed, and then the X-direction position is finely adjusted again to correct the deviation. As a result, the rail members 4a and 5a are held in the hoistway while being centered in the X and Y directions.

When the predetermined centering position to be installed and fixed is determined in this way, the rail member 4 held there is determined.
The bracket is assembled according to a and 5a, and the work of permanently fixing the rail members 4a and 5a to the hoistway walls 20 and 21 is performed. The details of the main fixing work will be described for the rail member 4a. As shown in FIG. 10, first, the rail side bracket 61 is attached to the centered rail member 4a using the rail clip 62, and the rail side bracket 61 is attached. After the wall side bracket 63 is attached to the hoistway wall 20, the wall side bracket 63 is fixed to the hoistway wall 20 by the anchor bolts 64 that are pre-mounted on the hoistway wall 20. At this time, if the mounting portion of the hoistway wall 20 is finished with a slight inclination with respect to the vertical plane, a gap G is created between the wall side bracket 63 and the hoistway wall 20, as shown in FIG. Therefore, in that case, the operator may fix the wall-side bracket 63 after filling the gap G with a liner or the like. The main fixing work of the rail member 5a that has been centered is also performed in the same manner.

As described above, in the above-described centering device, the first position adjusting means 4 is held while the base member 300 is held by the tension force between the hoistway walls 20 and 21 facing each other.
2, the slide member 38 is appropriately displaced with respect to the base member 300 in the X direction, and the second position adjusting means 481 and 482 grip the pair of left and right rail members (for example, the rail members 4a and 5a). Since the 35 can be appropriately displaced in the Y direction with respect to the slide member 38, the pair of rail members can be centered while maintaining a desired relative positional relationship. Therefore, compared to the conventional centering work in which the position of each rail member is adjusted by hitting the bracket temporarily fixed to the hoistway wall with a hammer etc., the work efficiency is significantly improved, and the installation work of the elevator guide rail is improved. It can be done in a short time. Further, when the above-described centering device is adopted, even when the hoistway walls 20 and 21 are not finished well, the rail member can be centered without exerting an undesired bending stress. Accuracy can be secured and reliability can be improved.

[0032]

As described above, the centering device for the elevator guide rail according to the present invention maintains the desired relative positional relationship between the pair of left and right rail members installed and fixed at the same height. Since centering can be performed easily, it is an excellent effect that work efficiency is significantly improved compared to the conventional centering work in which the position of the rail member is adjusted while hitting the temporarily fixed bracket with a hammer or the like. Play. Further, when the centering device according to the present invention is adopted, even when the hoistway wall is not finished well,
Since highly accurate centering can be performed without applying an undesired bending stress to the rail member, the reliability is improved.
