Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for driving a gondola that is moved up and down along the outer wall of a building to clean the outer wall and window glass of the building. When cleaning glass, in order to ensure safety and efficiency, a gondola is installed that moves up and down along the outside of the building, and a worker rides inside the gondola, or an automatic cleaning device is installed to achieve the desired purpose. ing.

Traditionally, the exterior walls of buildings have vertical lines in their design.
! Many of them are arranged in 4 scales, and the window frames on each floor are aligned vertically.Furthermore, the vertical guide rails for raising and lowering the gondola are installed along the entire height of the building, so the guides protruding from the gondolas are installed on these guide rails. The wheels are fitted, and the gondola is supported accurately and at any position in the height direction of the building by the guide rail wheels, so the gondola can be safely raised and lowered and also cleaned.

However, recently, a design has been proposed that emphasizes the horizontal lines of the exterior of the building, and in such a design, straight guide rails or guide grooves are not provided in the entire height direction of the building, and as shown in the figure, there are It will be provided in the shape of a broken line on the outer wall surface. Therefore, with conventional gondola support systems and drive methods, it is a detour to safely move the gondola up and down along the outer wall of the building.

In view of this, the present invention has been developed so that even if the guide rails are not in a straight line in the entire height direction of the building but are in the form of a broken line, the recessed window portions and the protruding outer wall portions are alternately arranged in the height direction of the building when the gondola is raised and lowered. In a building where the gondola is raised and lowered along the outer wall of the building, suction devices installed at the top and bottom of both the left and right sides are used to adsorb the gondola to the outer wall of the building. By selectively raising, lowering or stopping the side suction devices, at least two left and right suction devices are used to adsorb the gondola to the outer wall of the building, and the gondola is safely brought out by large guide arms protruding from the top and bottom of the gondola. The gist of the present invention is that the window cleaning device is installed on a gondola that moves up and down to automatically clean the window.

The present invention will be explained below based on illustrated embodiments.

In the figure, 1 is the main body of a building cleaning machine that runs on a rail R installed on the roof of a building so that the gondola can move up and down and move along the building wall. A lifting device, a traveling device for the main body, etc. are provided.

An arm 2 is provided projecting from the upper part of the main body 1, a wire rope 4 for hanging a gondola is extended by a sheep 6 provided at the tip of the arm, and a required gondola 5 is provided at the lower end of the rope 4. The gondola 5 may be a manned type with a worker on board, or an unmanned type and equipped with an automatic cleaning device. This gondola 5 is raised and lowered along the outer wall of building B using a wire loop 4, and as the main body 1 moves, the gondola 5 also moves laterally. is depressed compared to wall surface B'b, and in this building, guide grooves 6 are provided only on wall surface Bb. Therefore, in order to safely launch the gondola along the exterior wall of Building B, a special device is required to align the gondola with the exterior wall of the building, a device to prevent sideways vibration due to wind, etc., and a guide to always raise and lower the gondola vertically. equipment etc. are required. That is, the gondola of the present invention has guide arms 7 that protrude from the upper and lower parts of the gondola in the direction in which it is suspended.
a, 7bt-protrudes, this upper and lower guide arm 7a
, 7=b at least one or both of the windows on each floor B
Guide wheels 8a and ab protruding from the arms are fitted and supported in guide grooves 6 on the outer wall surface Bb of the floor vertically sandwiching the gondola, and the gondola is supported in the vertical direction, and is used for winding and unwinding the wire lobe. These guide wheels 8a and 8b allow the gondola to fully rise and fall, and also support the gondola so that it does not sway even in extreme winds.One of the guide wheels 8a contacts the inner surface of the guide groove 6, and fully restricts the lateral swing of the gondola. The other 8b is in contact with the bottom of the guide, and maintains a necessary gap between the building's outer wall and the gondola 8 to allow the gondola to move up and down and clean the windows even when the gondola is adsorbed to the building's outer wall. It is. With these upper and lower guide arms and the guide wheels protruding from the arms, the gondola is always supported by the guide groove no matter where it is in the height direction of the building, so that it can move up and down safely and smoothly. Eggplant.

Further, the gondola 5 is provided with a window cleaning device 9 that moves up and down in the vertical direction of the gondola. The configuration of this window cleaning device 9 is not limited as long as it can wipe away the thin window glass from the building's outer wall (Bl) and perform the required cleaning with a blade, rotating brush, etc. In particular, when this cleaning device passes through the building exterior wall Bbt, it is moved back so that the tip of the device does not come into contact with the exterior wall surface, and the window Ba
1C4j The gondola is moved forward so as to contact the window glass with the required pressure, and the gondola is raised and lowered in the height direction of the window independently of or synchronously with the elevation of the gondola.
When aK is reached, this window cleaning device M moves forward and descends or rises in the height direction of the window and within that range to perform the required cleaning. The gondola is accurately held along the outer wall of the building during window cleaning and when going up and down, and this is done by suction devices 10a and 10b provided on both sides and above and below the gondola. The upper side 10a of this suction device on both sides is fixed to the gondola so that it always suctions the outer wall surface of the building, and the other lower side suction device 10't) is fixed to the gondola in the vertical direction with respect to the gondola. It is designed to slide. For this reason, as shown in Fig. 6, the gondola moves up and down along the outer wall of the building, and the window parts Ba and the outer wall Bb are arranged alternately, so that even when the two parts are not flush, the horizontal lines of the building are emphasized. Even if the window Ba is recessed in the horizontal direction and the entire building has convex portions (wall surfaces) and concave portions G (window portions) arranged alternately in the vertical direction, any two suction devices 10a and 10b are always activated. Building exterior wall RCG & will be installed. Next, the operation of supporting the g& layer by the suction device during the ascent and descent of the gondola will be explained with reference to FIG. FIG. 6(1) shows a state in which window cleaning has been completed, the cleaning head has retreated, and then the gondola is lowered completely to the window on the lower floor. The lower adsorption device 1ob't is located at 'F descent t4 at approximately the same speed as the descent speed of this gondola.
- When the gondola is lowered, the lower suction device iob reaches the raised position as shown in FIG. position and suction becomes impossible, but the lower side I & layer device iob located at the wall surface Bb position
In this state, the gondola is further lowered completely, and as shown in FIG. 6 (3), both the upper and lower suction devices 10a and 10b are attached to the outer wall surface Bt of the same floor.
When 1C is adsorbed, the lower lf & of the gondola and the lower suction device 10b of the gondola both start to descend, and as shown in (4) in the same figure (5), the upper suction device is attached to the wall of the upper floor. When the lower G&layer table device is brought to a state where it is largely adsorbed to the wall of the lower floor, the lower F! While moving the gondola forward and bringing it into contact with the window glass, the cleaning device is lowered completely to clean the mess. After cleaning is completed, the cleaning head is moved back and raised to restore its original position.Then, the gondola is lowered again and the gondola is lowered again (see Figure 6). Return #1.? in the order of υ~(5),
The system automatically cleans windows from the top of the building to the bottom. Further, when the gondola reaches the ground, it is then moved laterally by one pitch to raise the gondola, and when the gondola is raised, the cleaning work pipe is also carried out in the same manner.

According to the present invention, when the gondola equipped with the cleaning device is fully raised and lowered, the lower suction device that attracts the gondola to the building's outer wall surface is selectively raised, lowered, or stopped as the gondola is raised and lowered, and the gondola is moved up and down to the building's outer wall surface. Even when the gondola has convex portions and concave portions arranged alternately in the vertical direction, it is always suction-supported to the outer wall of the building by at least two suction devices, so that the gondola can be raised and lowered safely and reliably. It has the advantage of being able to
