Generally speaking, mounting brackets, sills, doorway frames, accessories, etc. are installed from the hoistway side to floor-side entrances to the hoistway, but most of the installation work for these doorway parts is done using the hoistway. There is.

At present, the installation of doorway parts is carried out as shown in FIGS. 1 and 2.

As shown in FIG. 1, scaffolding 2 is set up in a cross-shaped structure within a hoistway 1, a scaffold board 2F is fixed thereto, and entrance/exit parts are attached. That is, anchor bolts 5 for fixing the mounting bracket 4 to the wall of the hoistway 1 are driven in, the threshold 5 and the pocket 7 for the entrance/exit door are lifted with an electric winch (not shown), etc., and these are attached to the hoistway. Center the piano wire 3 suspended in the ceiling 9 and fix it in place, and then carry the doorway frame 8 assembled on each floor (landing) into the hoistway 1 and align it from the floor side and from above the scaffolding board 2F. It was taken out and fixed.

However, the above work was carried out on unsafe scaffolding.
Moreover, since the work must be done at high places and movement on the scaffolding is dangerous, it is difficult to ensure safety, and as a result, the work of centering and installing the doorway parts takes a long time and requires a great deal of effort.

On the other hand, Fig. 2 shows a case where the hoisting machine 9, control panel 10, and speed governor 11 are installed in the machine room MR at the top of the hoistway 1, and the centering and fixing of the guide rail 12 is completed. be. In this case, using the guide rail 12, a wire rope 15 connecting the car frame 13 and the counterweight 14 is wound around the hoisting machine 9 and moved up and down, and the car frame 13 is used to transport the entrance/exit parts. I decided to install it. In this case, the reference for attachment is the car side sill 16.

According to this operation, relatively large parts can be assembled on the standard floor and transported by the car frame 13, making it easy to transport the parts and move the work position. However, in this case, the work cannot be carried out unless the hoisting machine 9 and the control panel 10 are installed in the machine room MR, which results in a longer work time for the entire elevator installation work, and the centering and installation of the doorway frame 8, etc. was exactly the same as the work shown in Figure 1, and there was a need for further improvement.

Centering devices 30C and 30D are provided at two locations A and 30B on a vertical line of the engagement piece 29C. Each of the above devices is arranged on the left and right sides of the work platform frame 19.

Reference numeral 31 denotes an automatic construction device installed toward the floor side entrance of the work platform frame 19, which performs various operations such as drilling holes in the hoistway wall surface 1W, cleaning, supplying bolts, and driving bolts. 32 is a level attached to the work platform frame 19.

Reference numeral 33 denotes a component lifting device, which is composed of a component holding section 34 and a guide section 35, and is suspended by a wire rope 36. The holding part 34 has a component gripping tool 3.
4A and 34B, and the guide portion 35 engages with the guide rail 12. The upper end of the wire rope 36 is connected to a guide device 37 on the work frame 19.
It is wound around an electric winch 39 on the work platform frame 19 via a guide pulley 38 fixed to the ceiling of the hoistway, the machine room, or the work platform frame 19.

Centering installation devices 40A and 40B are provided facing the floor side entrance of the work platform frame 19 and facing the component gripping tools 34A and 34B. The centering installation devices 40A, 40B are connected to the component gripping tools 34A, 34B, and are configured to be hydraulically movable in the direction of connection.

Next, the operation of the installation device configured as above will be explained. It is assumed that the guide rails 12, 12' have already been installed.

For example, when installing necessary entrance/exit parts for a floor-side entrance on the fifth floor, the work platform frame 19 is raised using the guide rails 12, 12' as guides. At this time, if the guide rail is accurately fixed according to the standard, it is necessary for the laser oscillator 17 to oscillate the laser beam 18 using this guide rail as a vertical reference line. However, the laser beam 18 is required when the robot moves up using a guide rail that needs to be readjusted after the installation is completed.

When the work platform frame 19 is raised, the hydraulic telescopic lifting legs 27 and 28 of the lower fixing devices 25 and 26 are extended. The laser oscillator 17 and the light receiver on the workbench frame 19 are designed and arranged so as to substantially coincide with each other on a vertical line.

Next, the engaging piece 29A of the upper fixing device 24 is extended to clamp the guide rail 12, and the work platform frame 19 is fixed. In this state, the elevating legs 27, 28 are retracted, and in the retracted position, the engaging pieces 29B, 29C are extended to clamp the guide rails 12, 12'. The work platform frame 19 is now separated from the pit 1P of the hoistway 1 (FIG. 3). After that, the upper fixing device 2
4 engagement piece 29A from the guide rail 12,
The elevating legs 27 and 28 are extended again, and then the upper fixing device 24 is fixed to the guide rail 12. By repeating the above operations, the work platform frame 19 is raised to a position where the automatic construction device 31 faces the set position of the anchor bolt 5 of the floor side entrance on the fifth floor. At this time,
The upper fixing device 24 is separated from the guide rail 12,
Guide rails 12, 1 with lower fixing devices 25, 26
It is holding 2'.

In this state, the hydraulic positioning device 22 is operated,
The plunger 23 is pushed against the hoistway wall surface 1W.
Then, the control device 21 calculates the horizontal movement direction and movement distance of the work platform frame 19 from the current value from the light receiver 20, and
sends respective signals to the control valve opening/closing circuits of the work platform frame 19 by adjusting the amount of extension of each plunger 23.
Move in two horizontal directions. This operation continues until the center of the light receiver 20 coincides with the laser beam 18, and after that, a predetermined pressure is applied to each plunger 23 to lock it and determine the vertical position. Of course, before starting this vertical positioning work, it is necessary to slightly move the lifting legs 27 and 28 so that the work platform frame 19 is level using the spirit level 32 to complete the horizontal centering work. Nor.

When the above horizontal centering and vertical positioning operations are completed, the upper fixing device 24 is held by the guide rail 12 by extending the engagement piece 29A. At this time,
If the position of the mounting bracket (not shown) of the guide rail 12 is aligned with the stop position of the work platform frame 19, the engaging pieces 29A, 29B, and 29C can be placed on the mounting bracket. Guide rail 12,1
2', the support of the work platform frame 19 becomes more stable.

Once the work platform frame 19 is fixed, the automatic construction device 3
1 is moved to the anchor bolt installation position, the horizontal distance from the work platform frame 19 to the hoistway wall surface 19 and the depth of the bolt hole are measured, and a hole for the anchor bolt 5 is drilled. After drilling the hole, compressed air is blown from the same device to clean the hole, and the anchor bolt 5 is inserted into the hole and the driving operation is performed.

Next, transportation and installation of the entrance/exit parts will be explained. After driving the anchor bolt 5,
The parts lifting tool 33 is lowered to the floor where the doorway parts are being assembled and the doorway parts are placed thereon. In this embodiment, the doorway frame 8 to which the mounting bracket 4 and the sill 6 are temporarily fixed is connected to the component grasping tools 34A, 34 of the component lifting tool 33.
Supported by B. Thereafter, the electric winch 39 is driven to wind up the component gripping tool 33. At this time, the component lifting tool 33 is moved to the guide rail 1 by the guide portion 35.
2, so it will not be harvested in the middle of winding. When the parts lifting device 33 is hoisted into a predetermined position, the electric winch 39 is stopped and locked. This operation may be performed, for example, by detecting when the stopper portion 33A of the component lifting tool 33 engages with the work platform frame 19, and by immediately turning off the electric power to the electric winch 39 and activating the controller.

After confirming that the component lifting tool 33 has stopped at the fixed position and the electric winch 39 has stopped, the control device 21 issues a command to the centering and installation devices 40A and 40B to contact the component grasping tools 34A and 34B of the component lifting tool 33. Move it to. Then, the component grasping tools 34A, 34B and the centering/installation devices 40A, 40B are connected, and the engagement between the component grasping tools 34A, 34B and the component lifting tool 33 is released. And the centering installation device 40A, 4
The amount of movement of 0B is determined by calculating and determining the installation position of the entrance/exit frame 8 using the control device 21, and controlling it by sending a signal to a hydraulic control circuit (not shown). The doorway frame 8 is moved to the installation reference position. After moving to a predetermined position, the temporarily fixed mounting bracket 4 is fixed to the anchor bolt 5, and the doorway frame 8 and the sill 6 are fixed to the fixed mounting bracket 4. At this time, the positions of the entrance/exit frame 8 and the threshold 6 are set by the centering installation device 40.
This is the reference position supported by A and 40B, and the deviation from the installation position of the mounting bracket 4 can be adjusted by intervening a spacer when fixing the mounting bracket 4, or by installing a long hole in the mounting bracket that can absorb the above deviation. This can be dealt with by setting it in 4.

After installing the entrance/exit parts, the centering installation device 40
Apply negative pressure to A, 40B to confirm that the entrance/exit parts are fixed, then release the negative pressure and remove the parts gripping tools 34A, 34.
Release the grip on B and return the component lifting tool 33 to its home position. Then, the connection with the centering installation devices 40A and 40B is released to complete the installation of the doorway components on the fifth floor. Thereafter, by repeating these operations, the entrance/exit parts for all floors are installed.

In this way, according to the embodiment of the present invention, the work frame 19
The lifting and lowering of the anchor bolts 5, the installation of the anchor bolts 5, the transportation of the entrance/exit parts, and the centering are performed mechanically using the work platform frame 19, thereby automating the centering work. Only fixing is required, and the work is simple and can be done in a short time. Furthermore, since this work can be performed on the work frame 19, safety is high even when working at high places.

Furthermore, since the device of this embodiment is equipped with elevating legs, there is no need to wait for the hoist to be installed in the machine room before performing installation work, unlike in the prior art.

Incidentally, in the above-mentioned embodiment, the work is carried out using guide rails 12 and 12' which need to be readjusted, but when the work platform frame 19 is raised, the work is carried out while readjusting the guide rails at the same time. You can also. In this case, the upper and lower fixing devices 24 to 26 are the guide rails 12 and 1.
Rather than ascending while holding the guide rail 2', it ascends while engaging with a guide rail mounting bracket (not shown) fixed to the hoistway wall. Then, a centering device 30A provided on the work platform frame 19
~30D, the guide rail for readjustment is grasped and positioned, and then fixed to the mounting bracket.

Incidentally, although the above embodiment uses a laser beam as the vertical reference line, it is also possible to use a suspended piano wire as in the conventional method.

Further, in the embodiments described above, each device is driven using hydraulic pressure, but the content of the present invention does not change even if a rack-and-pinion system or a motor gear system is used.

As explained above, according to the present invention, most of the installation work of entrance/exit parts can be mechanized, so the work time is shortened, the operator's movement is limited to a small area, and the work platform frame 1
It is safe because the work will be done on the 9th floor.

In addition, the installation accuracy of entrance/exit parts is highly accurate and uniform.
