Description

[Detailed Description of the Invention] Industrial Application Field The present application is a system for lifting and lowering a work gondola that is installed on a trolley that runs on rails laid around the roof of a building and that works on the outer wall of the building. The present invention relates to a hanging device for a working gondola to be lowered, and provides a hanging device for a working gondola that is particularly effective for working on the outer wall of a building whose outer wall surface is sloped in a diverging shape.

Conventional technology Conventionally, in order to suspend a work gondola from the rooftop for working on the exterior wall of a building, two booms that can be lifted up and down are mounted horizontally on a trolley that runs on rails laid around the rooftop. The work gondola is suspended by a hanging rope at its tip so that it can be raised and lowered, and the work gondola is moved closer to the outer wall by raising and lowering the boom. When moving from one exterior wall surface to the other exterior wall surface beyond a corner of a building, this was accomplished by using a combination of raising/elevating and rotating operations of the boom.

Problems to be Solved by the Invention However, according to this suspension device, the distance between the trolley and the work gondola can only be changed by raising and lowering the boom, and since it is necessary to operate two booms simultaneously, the structure In addition, there were inconveniences in use, such as the operation of moving the work gondola being troublesome and the rotation angle of the boom being restricted.

Means to Solve the Problem Therefore, the present application provides a system in which a boom is rotatably equipped on a cart, a self-propelled trolley is provided on a rail provided on the boom, and a work gondola is hung from the trolley in a rotatable manner. The gist of this is that the base of the boom is equipped with a swing mechanism on the top of the trolley that runs on the rails so that it can turn horizontally, and a guide rail is provided in the longitudinal direction of the boom. The present invention is characterized in that a self-propelled trolley is movably attached to the trolley, and the trolley is provided with a support arm for suspending a working gondola via a turning mechanism.

Effects and Examples FIG. 1 shows a side view of a work gondola C suspended by a hanging device A of the present invention installed on the roof of a building B having an inclined surface portion b.
1 is a self-propelled trolley that runs on rails 2 laid along the periphery of the roof of building B, and the base of a boom 4 is equipped on this trolley 1 via a large electric swing mechanism 3 so that it can rotate horizontally. and the boom 4
extends horizontally to the outside of Building B.
Reference numeral 5 denotes an H-shaped guide rail provided on the lower surface of the boom 4, which extends in the longitudinal direction of the boom 4, and a trolley 6 is attached to the guide rail 5 so as to be freely movable. As shown in FIGS. 3 and 4, this trolley 6 has wheels 8a and 8b that roll on the running surface of the guide rail 5 on a holding frame 7, a drive body 9 that drives one wheel 8a, and a small electric turning The swing mechanism 10 is provided with a support arm 12 that supports a hanging rope 11 on both ends of which the working gondola C is suspended. Winder 13 installed on the side
The work gondola C moves up and down by the rotation of this winder 13. In the figure, 14 is a balancer provided at the base end of the boom 4.

Therefore, in the hanging device of the present invention, by driving the driving body 9 and causing the trolley 6 to travel along the guide rail 5, the distance from the trolley 1 to the position of the work gondola C can be arbitrarily varied, and the work gondola C
can be freely brought close to the outer wall surface of the building, and by driving the winder 13 in this state, the working gondola C is raised and lowered along the outer wall surface.
Furthermore, by mutually driving the winder 13 and the drive body 9, the work gondola C can be moved along the slope b of the building, as shown by the imaginary line in FIG. Also, as shown in Figure 5,
When bringing the work gondola C close to the corner of the building B, the swing mechanism 3 is driven to horizontally rotate the boom 4, and the swing mechanism 10 is driven to change the direction of the gondola C. When moving from one outer wall surface to another outer wall surface, the trolley 6 is moved to the tip of the boom 4, the swing mechanism 3 is driven to swing, and the work is carried out by running the trolley 6 and driving the swing mechanism 10. The gondola C can be brought close to the outer wall surface as shown by the imaginary line in FIG.

Effects of the Invention Since the present application is constructed as described above, the distance from the truck to the work gondola can be freely varied only by running the trolley, and there is no need to look up and down the boom as in the conventional case. This makes it easy to operate and effective for working on the exterior walls of buildings with inclined surfaces.The boom can be rotated over a wide range and the direction of the work gondola can be changed at will, making it easy to work on complex exterior walls. It has the advantage of being convenient for working on external walls of buildings with double-sided structures and corners.
