Abstract

PURPOSE:To enable a gondola that has been lowered away from the projecting portion of a building to be moved again toward a wall face by disposing a boom on a frame in such a manner as to be horizontally slidable, and allowing the boom to suspend the gondola by means of wire. CONSTITUTION:A boom 9 is horizontally slidably passed through insertion portions 8, 8 set at the same height as a frame 7, and a gondola 2 is suspended from the end of the boom 9 by means of wire; i.e., the gondola 2 is provided in such a manner to be movable as the boom 9 is slid by the movement of a movement means 10 provided at that insertion portion 8 which is nearer to the extended side of the boom. If a wall face is projecting, the gondola 2 is moved forwards and lowered to avoid that projection, and when moved below the projection, the gondola 2 can be returned to the wall face up to a position where the wire approaches the projection, and so the serviceability of the gondola device can be enhanced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gondola device used when working on a wall surface of a building.

[0002]

2. Description of the Related Art Conventionally, when a work is performed on the wall surface of a building from the outside, a movable gondola device composed of a gondola and a carriage is often used, and the gondola is extended from the opening of the body. This gondola device is installed on the inside of the building so that the gondola suspended by wires can be raised and lowered.

[0003]

However, as shown in FIG. 6, in the above-described conventional gondola device a, the boom c for suspending and supporting the gondola b is fixed to the carriage d. If there is a balcony or other overhanging part on the outer wall, it may not be possible to lower the gondola and you may not be able to use this gondola device, or even if you can lower the gondola,
As shown in FIG. 7, the work is difficult to perform because the gondola b is separated from the wall surface. And instead of this gondola device, there is also a method of attaching a trolley beam to the outer circumference of the middle floor so that the gondola can travel, or taking out an arm from the main beam and suspending the gondola with the arm protruding outward. However, installation and removal of the equipment for supporting the gondola is extremely complicated, which requires time and effort.

In view of the above-mentioned circumstances, it is an object of the present invention to make it possible to move the lowered gondola to the wall surface side again while avoiding the projecting portion of the building. The task is to make it easy.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems. A boom is slidably arranged horizontally on a carriage, and a moving means for sliding the boom is provided. It is intended to solve the above-mentioned problems by providing a gondola device characterized by suspending a gondola via a wire. In addition, a plurality of bogies are arranged side by side and connected between the bogies. It is intended to provide a gondola device in which a plurality of carriages are detachably connected via a member.

[0006]

In the present invention, since the boom is provided so as to slide, by advancing the boom, it is possible to avoid the overhang even if there is overhang and to lower the gondola. By retreating, the gondola can be brought closer to the wall. Also, it is equipped with a plurality of carriages, and it becomes possible to separate the plurality of carriages that support the gondola up and down when necessary.

[0007]

EXAMPLES The present invention will be described in detail with reference to the examples shown in FIGS. In the figure, reference numeral 1 denotes a gondola device, and the gondola device 1 comprises one gondola 2 and a pair of carriages 3 supporting the gondola 2. Although some of the figures show only one half of the gondola device 1, the other half not shown has the configuration described below. The trolley 3 is provided with a frame 7 formed by assembling a plurality of pillars 6 in a mountain shape on a pedestal 5 equipped with wheels and capable of raising and lowering the jack-ups 4 at four corners, and the frame 7 has the same height. Booms 9 are horizontally slidably attached to the two insertion portions 8 set in the portions. A moving means 10 for sliding the boom 9 using a motor as a drive source is provided in the insertion portion 8 on the forward side (boom insertion direction), and the operation of the moving means 10 causes the boom 9 to move forward. You will come back.

A gondola 2 is suspended from the boom tip through a wire. That is, the above-mentioned moving means 1
By the movement of 0, the boom 9 slides,
This gondola 2 is provided so as to be able to move in the horizontal direction, and if there is an overhang on the wall surface, lower the gondola while it is moved forward to avoid the overhang. When the gondola moves downward from the overhang, the gondola can be returned to the wall surface side until the wire approaches the overhang.

As shown in the figure, the gondola 2 is provided with a hoisting machine 11 for winding and unwinding a wire connected to a boom 9, and the operation of raising and lowering the gondola 2 is controlled by the operation from the gondola side. Is provided. As described above, in the embodiment, the hoisting machine 11 for raising and lowering the gondola 2 is installed on the gondola 2, but the hoisting machine itself is installed on the trolley 3 side and the wire is unwound through the slidable boom 9. It may be rolled up or rolled up. A drive mechanism and a steering mechanism for moving the cart 3 are provided below the platform 5 of the cart 3. The configuration is shown in FIG. 5, where 12 is a steering unit and 13
Is a steering / drive wheel, and 14 is a drive device for operating the wheel 13.

FIG. 4 shows a connected state of the pair of carriages 3 when supporting the gondola 2, and the pair of carriages 3 are connected by a plurality of stays 15 which are connecting members bridged between the bases 5. The gondola 2 is supported by the pair of carts 3 in this connected state. Since the carriage 3 has the drive mechanism and the steering mechanism as described above, various movements and orientation adjustments of the entire apparatus are performed by combining movements of the coupled carriages 3. When the rearrangement is performed, the stays 15 are removed and the stays 15 are divided into individual units, which are moved or loaded on a lift.

[0011]

As described above, in the gondola device of the present invention, the boom is horizontally slidably arranged on the carriage and the moving means for sliding the boom is provided, and the boom is connected via the wire to the gondola. It is characterized by suspending. This allows the boom to move forward even if there are overhangs on the wall and then lower the gondola to avoid the overhang, and pulling back on the boom pulls the gondola onto the wall until the wire approaches the overhang. It is possible to improve the utilization of the gondola device. Furthermore, since the boom is slid horizontally, it can be used on a floor with a small vertical height compared to a boom lift type gondola device installed on the rooftop floor.

Further, since the gondola is supported by a plurality of separably connected bogies, each bogie can be made smaller and lighter in weight, and a plurality of bogies can be separated to move or lift them. Can be loaded, making it extremely easy to rearrange the gondola device. In addition, the distance between the bogies can be increased, and the stability of the gondola increases, and the movement of each bogie in the connected state causes various traveling patterns, enabling complex traveling operations and extremely easy position adjustment of the gondola It has a practical effect.
