DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building gondola facility for performing work on an outer wall of a building, such as a window cleaning operation.
More specifically, the present invention relates to a vehicle provided with a bogie provided with wheels for moving on rails laid on a rooftop floor.

[0002]

2. Description of the Related Art In this type of conventional gondola equipment for buildings, a bogie moves only on rails.

[0003]

According to the above prior art, since the truck is of a track type in which the truck moves on rails, the position and position of the truck are smaller than those of a trackless type in which the truck moves on the floor surface. The posture is stable, and there is an advantage that the position accuracy of the cage suspended and supported by the cart can be maintained well, and the workability and safety of the cage can be improved. But,
According to the prior art, when a truck is to be stored in a tower or a high-rise building, the rails must be drawn into the tower or the high-rise building, so that there are the following inconveniences. In other words, the rails extend between the tower and the high-rise building (indoors) and the roof (outdoors), and the structure of the joints between the tower and the high-rise buildings and the roof, the entrance and exit, and the waterproof structure become complicated. Make design and construction difficult. In addition, since rails must be provided as fixed equipment in towers and high-rise buildings, a special space for installing rails and passing carts is required in towers and high-rise buildings. Squeezing the internal space. This leads to a significant cost increase. Furthermore, in buildings, the rooftop is sometimes divided into two sections by towers and high-rise buildings. In such a case, rails are provided so as to cross the towers and high-rise buildings, and the two rooftop rails are unified. By doing so, it is possible to work on the outer wall of the building around the circumference while using only one truck,
In this case, since the rails enter the tower or the high-rise building, the cost is increased similarly to the above. But,
However, if the rails on the two roofs were separated, it would be necessary to have one truck on each of the two roofs in order to be able to work on the outer wall around the building. Invite you. in short,
According to the conventional technique, there is a drawback that the cost is increased when the truck is stored and when applied to a building divided into two roofs in a tower or a high-rise building. An object of the present invention is to eliminate the above disadvantages.

[0004]

A feature of the gondola equipment for a building according to the present invention is that the cart is equipped with a second wheel for moving on a floor, and a first wheel for moving on a rail by the wheel. This is characterized in that a movement mode switching means for switching between the mode and the second mode in which the second wheel moves on the floor surface is provided.

[0005] Then, the movement mode switching means moves the wheel or the second wheel to a first position where the vertical distance between the lower ends thereof is smaller than the height of the rail from the floor surface, and to the second position. Means for changing the position of the lower end of the two wheels to a second position where the lower end is located below and the vertical distance is greater than the height, or the lower end of the second wheel is located below the lower end of the wheel And the second wheel is disposed at a position where the vertical distance between the wheel and the lower end of the second wheel is smaller than the height of the rail from the floor, and a wheel on the rail at the longitudinal end of the rail. It is preferable that the entrance and exit road surfaces are provided in such a manner that the height of the road surface gradually decreases as the distance from the rail increases.

[0006]

Since the moving form of the carriage is switched between the first form moving on the rails and the second form moving on the floor, the outer wall is switched by switching to the first form. Work can be done in orbit, while the second
By switching to the form, trolleys can enter and exit the towers and high-rise buildings using the common entrances formed in them, and the movement of the trolleys inside the towers and high-rise buildings is formed within them Can be performed using
When storing a truck in a tower or a high-rise building, it is only necessary to secure a space large enough to accommodate the truck. In short, there is no need to draw rails into the tower or high-rise building when moving the trolley into or out of the tower or high-rise building, making the design and construction of the building difficult, or making the tower or high-rise building difficult. There is no unreasonable pressure on the internal space.

[0007] In particular, when means for changing the position of the wheel or the second wheel relative to the first position and the second position is employed as the movement mode switching means, the first position is set at the first position.
Since the mode can be switched by the carriage alone such that the second mode can appear at the second position, the rail can be simplified.

On the other hand, when means for providing an ingress / egress road surface with an inclined posture is employed as the movement mode switching means, the second wheel is grounded on the floor surface as the vehicle exits the rail of the truck using the ingress / egress road surface. And the wheels are lifted off the floor to switch from the first mode to the second mode, and the wheels are grounded on the rails as the bogie enters the rails using the approaching / exiting road surface. The wheels float from the floor and switch from the second configuration to the first configuration. As described above, since the moving configuration does not require a movable configuration for changing the position of the wheels or the second wheel up and down, the structure of the bogie can be simplified while switching the moving configuration.

[0009]

According to the present invention, therefore, the position accuracy of the cage at the time of work can be maintained well, and the workability and safety of the cage can be improved, while the bogie can be used as a tower or high-rise building. When storing in a tower or in a building with two rooftops divided into two towers or towers, there is no need to pull rails into the towers or towers when using a single truck. You can now avoid up.
