Description

[Detailed Description of the Invention] The present invention relates to a work gondola suspension device for suspending a work gondola along the wall of a building for cleaning, painting, etc.

Generally cleaning walls of structures such as buildings and tanks,
When performing repair work such as painting or restoration, a work gondola is suspended along the wall of the building.

However, attached structures such as eaves, rain gutters, and handrails are often installed near the boundary between the roof and wall of a building, and these attached structures can become an obstacle to the building's wall. In many cases, it was difficult to hang work gondolas.

Therefore, in view of the above-mentioned conventional drawbacks, the present invention aims to provide a suspension device for a working gondola that can easily suspend the working gondola even if there is an obstacle near the boundary between the roof and wall of a building. purpose. To achieve this purpose, the present invention has a structure in which, in a work gondola suspension device that suspends a work gondola along the wall of a building, a balance weight is connected to a balance wire that hangs the work gondola, and the work gondola is suspended from the roof of the building. A fulcrum leg that supports the roof and is equipped with a roller for moving the roof, and a fulcrum leg that suspends the work gondola and supports it on the wall of the building and is equipped with a roller for moving the wall. It is characterized in that it consists of a saddle-shaped frame connected to straddle an obstacle provided on an object, and the balance weight is supported by a support device that can move in a direction parallel to the wall surface.

Embodiments of the present invention will be described below based on the drawings.

The suspension device of the present invention is constructed using Yajirobee's principle, and a first embodiment thereof is shown in FIG. 1, and a second embodiment is shown in FIG. 2.

The first embodiment is constructed with a saddle-shaped frame 4 that can cope with the case where the obstruction of the building is an eaves 2A of the roof 1 or a rain gutter 2B provided on the eaves 2A. This saddle-shaped frame 4 has ends of a fulcrum leg 6 supported on the roof 1 of a building and a tension leg 7 supported in a tension manner on a wall surface 3, such as an eaves 2A, a rain gutter 2B, etc. that protrudes from the roof 1. They are formed in a so-called saddle shape in which they are connected to each other across an obstacle. A balance weight 18 is suspended from the upper end of the fulcrum leg 6 of the saddle-shaped frame 4 on the opposite wall side of the building. A balance wire 9 is attached, and a pulley 10 for suspending the gondola is attached to the other supporting leg 7.
A working gondola 14 is installed by passing the wire 13 across the
It is configured so that it can be suspended. Further, a roller 5 for moving the roof and a roller 8 for moving the wall surface are attached to the tip of the fulcrum leg 6 and the tip of the tension leg 7, and the roller 5 for moving the roof is attached to the fulcrum leg 6. A driving moving motor 11 is installed, and the saddle-shaped frame 4 can be moved horizontally along the wall surface 3 (from the back side to the front side of the paper in the figure) by driving the moving motor 11.

In such a device, the working gondola 14 is suspended in a state balanced by the balance weight 18 using the fulcrum leg 6 as a fulcrum according to Yajirobe's principle. In this case, the roof moving roller 5 and the wall moving roller 8 are
Since the configuration is balanced according to Yajirobee's principle, each can be configured with one piece. In addition, there are one and two rollers for roof movement and wall movement,
If it is composed of a combination of 2 and 1 or 2 and 2,
It is also possible to create a more stable structure.

In the second embodiment, when the obstacle provided in the building is a handrail 2C, the saddle-shaped frame 4' is configured to straddle the handrail 2C. This saddle-shaped frame 4' differs from the first embodiment in that the fulcrum leg 6 and the tension leg 7 are different from the handrail 2C.
Arm 1 is connected across the
2 protrudes almost horizontally, and a pulley 10 for suspending the gondola is attached to this arm 12. In the figure, 9 is a balance wire, 11 is a moving motor, and 14 is a working gondola.

As shown in FIG. 3, the above-mentioned suspension devices 4 and 4' have a working gondola 14 suspended on one wall and placed on the roof of the building, and a movable gondola 14 on the opposite wall of the building. A pulley 17 provided at the tip of a pole 16 erected on the support cart 15
It is used by supporting the balance wire 9 and suspending the balance weight 18. When working,
In the state shown in FIG. 3, the work gondola 14 is moved up and down along the wall surface 3 by a drive motor provided in the work gondola 14 to perform cleaning or other work. Further, when horizontally moving the work gondola 14, the moving motor 11 of the saddle-shaped frames 4, 4' drives the roof moving roller 5 of the fulcrum leg 6, and at the same time, the balance weight 18 is moved to the support cart 15.
This is done by moving equivalently by .

As explained above, according to the present invention, the fulcrum leg, which serves as a fulcrum on the roof of a building, and the tension leg, which extends from the wall surface, are connected to the roof/wall surface of the building by utilizing Yajirobee's principle. By constructing the structure with a saddle-shaped frame connected to straddle obstacles installed near the boundary, the work gondola can be suspended without being affected by incidental structures such as eaves, rain gutters, and handrails. Also, it is possible to avoid the risk of damaging the above-mentioned auxiliary structures as in the conventional case.
