The present invention has been made in view of such a situation in the prior art, and has as its object to reduce the operating cost with a simple configuration and to provide a passenger who can smoothly install a passenger conveyor. An object of the present invention is to provide a conveyor installation device.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an apparatus for installing a passenger conveyor in which a frame forming a main body of the passenger conveyor is integrally lifted and installed at a predetermined position. A column that can be raised and lowered on the floor near the getting-on / off section and that can be tilted in the direction of the frame, and a column holding portion that is connected to the floor at one end and that is connected to the column at the other end and that can expand and contract. A lifting machine provided on an upper portion of the support, for lifting the frame via a suspension, and a support for supporting the support when the support is attached to the floor and tilted toward the floor. Means.

[0007] In the present invention having the above-described structure, the column which is erected upright on the floor near the entrance / exit of the passenger conveyor is held by the column holding portion, and the column is expanded and contracted by the column holding portion. In a state of being tilted and tilted in the direction of the frame, it can be lifted through a suspension body by a hoist provided on the upper part of the column. Thus, the installation device has a simple configuration, and the operation cost can be reduced. Further, when the above-mentioned strut is inclined to the floor side for attachment or detachment, since the hoist and the strut are supported by the supporting means in a state where the crane is separated from the floor surface, an attachment portion between the crane and the strut is provided. Can be prevented, and the installation work of the passenger conveyor can be performed smoothly.

After the frame 3 is installed at a predetermined position between the upper floor 1 and the lower floor 2 in this manner, as shown in FIG.
When the other frame 3a is installed between the lower floor 301 and the upper floor 201, as described above, the fitting 27
Are hanging holes 27b at positions protruding from the short width of the frame 3.
, So that the chains 28,
When the chain 28a is fixed, as shown in FIG. 7, these chains 28, 28a can be hung on both sides of the installed frame 3, so that the hoists 14, 14
a through the chains 28, 28a to other frames 3
a can be lifted.

After the installation of the frames 3 and 3a is completed as described above, as shown in FIG.
The hoisting machine 14 is supported by the supporting means 38 provided on the floor 1a.
The column 12 is removed from the floor 1a while being supported so as to be separated from the floor, and similarly, the installation device 11 on the lower floor 2 side
The supporting column 12a is removed from the floor 2a while the lifting machine 14a is supported so as to be separated from the floor 2a by a supporting means provided in the floor.

In this embodiment constructed as described above, a lifting machine 14 is provided above the column 12 on the upper floor 1 side.
2 is held by the column holder 13, and the column 12 is tilted by the expansion and contraction of the column holder 13, so that the lifting machine 14 can be moved in the longitudinal direction of the frame 3. That is, since the configuration is simple, the cost can be reduced. In addition, as long as there is space for installing the column 12 and the column holding portion 13, the installation device 10 on the upper floor 1 can be installed, and the installation device 11 on the lower floor 2 is the same.
It can be used in relatively narrow installation sites.

Further, in this embodiment, since the column 12 is supported by the support means 38 so that the lifting machine 14 on the upper floor 1 is separated from the floor 1a as shown in FIG. Work for attaching the support 12 to the fulcrum portion 15 without damaging the attachment portion between the support 12 and the support 12a.
Can be performed smoothly from the floor surface 1a.
Further, the same applies to the installation device 11 on the lower floor 2 side.

In this embodiment, even when the frames 3 and 3a are vertically overlapped as shown in FIG. 7, it is not necessary to change the fixing positions of the installation devices 10 and 11, so that a plurality of frames 3 and 3a are required. , 3a can be installed efficiently.

In this embodiment, when the lifting machine 14 is displaced from the vertical line passing through the suspension point of the frame 3 in the short direction of the frame 3, the lifting machine 14 is slid along the beam 20. By being located on the vertical line,
The frame 3 can be lifted vertically by the hoisting machine 14. Further, the width of the end of the frame 3 varies depending on various models, but by sliding the two lifting machines 14 installed on the beam 20, the two widths of the two ends are adjusted according to the width of the end. The distance between the hoists 14 can be adjusted to lift two different places at the end. Thereby, the installation work can be performed in a stable state without the frame 3 tilting in the short direction.

Further, in the present embodiment, generally used members such as the screw rod 23 and the turnbuckle 24 are used as the expansion and contraction member for expanding and contracting the column holding portion 13, so that the cost can be reduced from this point as well. be able to.

In the present embodiment, the installation devices 10 and 11 are installed on the upper floor 1 and the lower floor 2, respectively.
