Further, a linear guide 38 is connected via a connecting rod 37, and a rail bracket nut runner 39 is vertically movably mounted on the linear guide 38.

Further, a nut feeding device 40 is provided in the lower left and right inside of the rail guide gripping device 28, and a vertical movement direction position detecting device 41 is provided under the inner wall surface of the hoistway of the rail guide gripping device 28. There is. Further, on the back side of the rail guide gripping device 28 (on the side opposite to the inner wall surface of the hoistway to which the rail is attached), the position of the piano wire 23 in which the piano wire 23 stretched vertically in the hoistway is inserted is detected. A pair of reference detection devices 42 (see FIG. 4) are provided for this purpose.

By the way, in a building having a steel frame structure, a separator beam 44 is laid over the mounting position of the rail bracket, and the fastener beam 4 is preliminarily arranged at a position corresponding to the mounting position of the rail 61 on the separator beam 44.
5 is fixed by welding. This fastener 45
Work device fixing holes 46 are drilled in two places on the left and right,
In addition, the bolt 4 for fixing the rail bracket 47
8 are attached.

On the other hand, the rail bracket 47 has an L-shaped cross section as shown in FIG.
2 and two rail centering holes 50 are formed on each of the left and right sides.

When the rail is attached to the inner wall surface of the hoistway, the piano wire 23 is first stretched vertically from the ceiling to the floor manually. The piano wire 23 is used as a vertical reference when centering the rail 61 to be installed, and two piano wires are used for one row of rails. Further, the hoist 80 is installed in the machine room 71, and the rail suspension wire 2 wound around the hoist 80 is installed.
Drop 5 to the floor. Further, one lifting wire 22 is hung for each row of rails to be installed from the ceiling.

Therefore, first, manually connect the rails 61 and 62 in the lower part of the hoistway sequentially for the entire length or several rails,
Centering is performed, and they are integrally lifted by a winch 64 provided in the machine room 71. That is, the hoist 80
Manually attach the rail suspension wire 25 wound around the wire to the rail suspension wire 51, and further attach the rail suspension tool 51.
The uppermost rail is lifted by 4 and the next rail is leaned against it, and the two rails 61 and 62 are connected and lifted by the fish plate 52.
A rail bracket 47 is attached to each of the rails 61 and 62 in advance, and the separator beam 4 is actually attached by the clip 53.
Temporarily fix it to the position where it will be fixed to 4. Also, the rail bracket 47 is clipped to the second and subsequent rails 53.
Thus, it is temporarily fixed to a position slightly above the position where it is actually fixed to the separator beam 44.

Next, manually loosen the clip bolt 54 of the rail bracket 47 temporarily fixed to the bottom rail, and insert the rail centering hole 50 of the rail bracket 47 into the bolt 48 of the fastener 45. Lower them and temporarily fix them with nuts. At this time, the rail centering hole 50 is formed to be larger than the diameter of the bolt 48, and the rail bracket 47 has a horizontal direction (X direction) parallel to the inner wall surface of the hoistway and a direction (Y direction) orthogonal thereto.
Direction) and rotation about the vertical axis to some extent.
By using 3 as a vertical reference, the lowermost rail 61 is centered. And then the rail bracket 4
7 and the fastener 45 are fixed again with a nut, whereby the lowermost rail 61 is centered and fixed.

Therefore, the rail gripping tool 30a of the centering and fixing robot 21 for installing the elevator rail is left open in the left-right direction, and the rail 6 at the bottom of the rail gripping tool 30b is opened.
The centering and fixing robot 21 is pressed so that the upper surface of 1 touches. Then, when the rail gripping tool 30a is returned to the original state, the spring 31 pulls the rail gripping tool 30a, so that the side surface and the upper surface of the lowermost rail 61 are pressed as shown in FIG. 21 can be moved only along the rail 61. Then, at that position, the output values of the two reference detection devices 42 attached to the rail guide gripping device 28 are read to confirm the position of the piano wire 23.

Next, the centering / fixing robot 21 is guided by the rail 61 by the elevating device 21a to be lifted from the lowermost rail 61 to the rail above it. At this time, the locator pin 36 and the bracket nut runner 39 are arranged at positions where they do not interfere with the vertical movement.

In this way, when the centering and fixing robot 21 moves up and the vertical position detecting device 41 detects the vertical position of the fastener 45 to which the rail bracket 47 should be fixed, the vertical stop is stopped there. So table 3
5 and the lifting device 21a are used to move the locator pin 36 in the front-rear direction and the up-down direction, the working device fixing hole 46 of the fastener 45 is inserted into the locator pin 36, and the centering-fixing robot body 27 is fixed to the fastener 45. .

Next, the position of the piano wire 23 passing through it is read by the two reference detecting devices 42 attached to the rail guide gripping device 28, and the difference between this value and the initial value measured before rising is read. To calculate. Then, with respect to the centering fixed robot main body 27 fixed to the fastener 45, the front and rear (Y direction) and the left and right direction (X direction) are adjusted so that the position deviation of the rail guide holding device 28 previously calculated through the table 29 is eliminated. ) And around the vertical axis to center the second rail 61 gripped by the rail guide gripping device 28. In this case, the rail restraining hole 50 of the rail bracket 47 is made larger than the diameter of the bolt 48, and the rail bracket 47 can be moved within that range to correct the position of the rail 61. be able to.

Therefore, the bracket nut runner 34 is engaged with the clip bolt 54 of the clip 53 of the rail bracket 47 that has been temporarily fixed in advance to loosen the clip bolt 54, and the rail bracket 47 moves up and down. Make it move to Then, the table 33 is lowered with the clip bolt 54 held by the bracket nut runner 34. Here, the nut received from the nut supply device 40 by the clip nut runner 39 is inserted into the bolt 48, and the rail bracket 47 is screwed to the fastener 45.

The position of the rail can be corrected and fixed by repeating these operations thereafter. In this way, the rails 61 suspended in a row from the top are fixed to the steel structure building one by one in order from the bottom by adjusting the positions with the fixing brackets, or the rails 61 are fixed on the rails 61 already fixed. You can connect the rails one by one and fix them with the fixing brackets.

This work is carried out for four rails 61, 62, and the rails 61, 62 are reached up to the longitudinal intermediate portion of the hoistway 63.

The rope 78 wound between the car frame 75 and the counterweight 77 has a length such that the counterweight 77 is located at the lower part of the hoistway when the car moves to the middle part of the hoistway so that the car frame 75 does not come off the rail 61. I am doing it. In this state, the work of attaching the entrance / exit device (not shown) in the lower half of the hoistway is performed from above the car floor 76.

Next, as shown in FIG. 10, the car side upper rail 79 of the hoistway 63 is integrated in the same manner as the car side lower rail 61. This integrated car-side rail moves to the upper ends of the lower rails 61 and 62 whose lower ends are fixed by the hoist 80. Next, it moves to the upper end of the lower rail 61 which is centered and fixed to the car frame 75. The upper rail 79 is manually connected to the lower rail with the joint plate 69 from above the car frame 75. These are carried out for four rails, that is, the car side rail 61 and the counter weight side rail 62.

Next, the above-described rail centering / fixing robot 21 (not shown in FIG. 10) is arranged at the lower end of the uncentered upper rail 79, and the rail is fixed to the building side while rising along the rail. I will do it. The above work is carried out for the four rails, and the fixing to the upper part of the hoistway 63 is completed.

Next, at the end of the rope 78 of the hoist 80 disposed in the machine room 71 above the hoistway 63, the car room 8
