Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for changing the direction of a gondola used when cleaning the exterior walls and window glass of a building at a corner of a building. This is to ensure that the gondola can be fully repaired even on the corner wall without using any.

Conventionally, when cleaning building exterior walls and window glass, a gondola is moved up and down along the entire building exterior wall from a moving body installed on the rooftop automatically, or a worker rides on the gondola and performs the desired work. is being carried out. L Z)-L When this gondola is bent to face the outer wall of a building, that is, at a corner of the building, the direction of the traveling body must be changed so that the gondola follows the outer wall of the building.

Therefore, in the past, at the corner of a rooftop, the rails supporting the traveling body were curved into an arc shape so that the traveling body could easily change its direction, and at least a space between two orthogonal rails was used. A large turntable is placed on which the entire traveling body can be transferred, and the turntable rotates to move in that direction. It is being converted. For this reason, the traveling body at the corner of the building will completely change direction at a position slightly away from the corner of the building's outer wall, and the gondola will move away from the outer wall surface at the corner of the building.

Therefore, if there are windows that extend to the corners of a building and require cleaning, it will be impossible to do so with an automatic machine and the work will have to be done by a worker.V! Even if the gondola is mounted on the building, the gondola is separated from the building's outer wall, forcing the worker to lean over and work, which is extremely dangerous work.

In view of this, the present invention aims to ensure that the gondola follows the outer wall of the building even at the corner of the building, and to change the direction of travel and rest using a simple device, and is based on the embodiment shown below. I will explain.

In the figure B1. B2 indicates the outer wall surface of the building; L1 is the building corner angle St-1 whose direction is different at each corner of the building;
As shown in the figure. On the roof of this building, there is an inner fixed rail la parallel to each of its outer walls.

lb and the outer fixed rails 2a and 2b'i are laid at a predetermined interval between both the inner and outer fixed rails.

This is fixed at a predetermined position on the rooftop via pace S as in the past. Fixed rails la, 2a and 1b.

2b and 2b are different in direction from each other as shown in Figure 1.2, and are almost perpendicular to each other, but at the corner where both rails intersect, there is a building q) that matches the angle formed by the outer wall of the building. Eggplant.

And these fixed rails la, lb, and 2a on both the inside and outside.

The tip of 2b is connected to the rail la9ga along wall B1 and wall B
It is cut in an oblique direction so as to be parallel to the bisecting axis of the angle that intersects with the rails 11) and 21) along the rails 11) and 21).

A gondola direction changing device is disposed in the middle where the rails la, 2a and tb, zb intersect.

As shown in detail in FIGS. 3 and 3, this consists of two guide rails 4.
4 is laid, or the level of this guide rail 4 is lower than the level of the above-mentioned inner and outer fixed rails.

A movable trolley 6 is provided on the parallel guide rails 4.4 so as to be freely movable. This truck is provided with a plurality of wheels 6 so as to support the truck body and the load tube of the gondola traveling body temporarily transferred onto the vehicle. The carriage is supported by and rolls, causing the carriage to reciprocate. In addition, the guide rollers 7 are protruded from the cart so as to come into contact with the side surfaces of the guide rails, which prevents the cart from tilting while the moving cart 50 is traveling and allows the cart to travel while always maintaining an accurate position.

On the movable trolley 6, pipes are connected between the inner fixed rails 1a and 1b and the outer fixed rails 2a and 2b, which are arranged so as to intersect at an angle of 90 degrees L<ri, and form a single rail. Alternatively, a rail is provided so that the traveling body is guided to the corner of the building. This rail is the fixed rail la on both Pg sides.

Two types are provided: an inner turning rail 8a that is curved in an arc shape between 111 and an inner transfer rail 8b that has a straight line LfC with one end slightly curved on the opposite side that abuts against the inner fixed rail. Rail sb [each inner fixed rail la
, lb, and are combined in a cross shape so that one end of each is abutted against each other. And this rail 8a.

8b is the same as the level of the inner fixed rails la, lbσ), and the distance between the axis of the end of the inner circle revolving rail and the axis of the end of the inner circle @ transfer rail 8b is equal to 111r1, and the outer pot as described later is The distances between the respective end axes of the turning rail 9a and the outer transfer rail 9b are also made equal.

There are also two inner transfer rails ab that intersect with each other.

A turntable 8Ctl which can be rotated manually or otherwise is provided at the fork point of 8b, and both rails 8b and 8b are cut out at the turntable 8C, and the rail 8b and 8b are cut out on the turntable 8C. By rotating the IP turntable, the turning rail 5a provided so as to be at the same level is aligned with the notch of one of the rails 8b to form a single line. This means that the running body is from the inner fixed rail la@
Or, adjust by rotating the turntable depending on which direction you want to run from the tb side. In Figure 2, L7 is made to run from the inner fixed rail 1a side.
'(Indicates the case.

It is curved to the outside turning rail 9a provided on the movable cart and fixed on the inside and outside! The curvature of this rail 9& is the same as that of the inner turning rail 8.
I! This internal disaster rail 8a shall be greater than L.
, 9a, the running body is fixed rail la, lb from the 2a side,
2b@ or in the opposite direction. An L-shaped external transfer rail 9b is provided on the outside of the outer swing rail 9a.
Both ends of b are connected at fixed positions at the same level as the ends of the inner and outer fixed rails.

This outer transfer rail 9b is the outer fixed rail 2a.

When the inner transfer rail 8b is connected to the end of the inner fixed foot rail 8b, the inner transfer rail 8b is also connected to the end of the inner fixed foot rail la, It), and when the outer swing rail is connected to the outer fixed rail end, the inner swing rail is also connected. The relative position tv of each rail 8a, 8b+9a, 9b shall be determined so that it is linked to the inner fixed rail.

When the gondola is moved to the outer wall of the entire building, for example, to the corner of B1 using the device formed as described above, the inner and outer transfer rails 8 b and 9 b'f are used as shown in FIG.
Constant lay in both the medial and lateral directions la.

When six mobile carts are moved so as to be connected to 21L, rails la, 8t) The gondola can now be advanced to the position shown in Figure 1. Similarly, the gondola can be advanced to the corner of the building's outer wall surface B2. The wheel position of the traveling body at this time is 1tt, which is shown by the inclined portion in FIG.

When moving the gondola from B1 to B2 or from B2 to B1111j, that is, to imitate the direction, the gondola at the corner of the building's outer wall is moved back a little to make the traveling body move away from the top of the moving truck. Next, the direction of the gondola is easily changed by moving the movable cart in the direction of the arrow in FIG. 2 and linking the inner and outer intramedullary fixed rails and the inner and outer inner turning rails.

According to the present invention, the gondola can be guided to the corner of the outer wall of the building by providing a movable trolley equipped with a turning rail and a transfer rail without using a large turntable between the rails that intersect in different directions. There is an advantage in that the direction of the gondola can be easily and reliably changed by simply moving the movable cart and changing the rail system by connecting it to the fixed rail.
