DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention is intended to solve the above-mentioned problems, and a plurality of wall adsorbing moving bodies move while adsorbing and fixing to a glass, wall surface, etc. of a building. Even if one of the suction parts is separated from the wall surface, the other suction parts automatically control the pressure so that the suction condition with the wall surface can be continued. At the same time, it is possible to adsorb a plurality of adsorbing portions separately without pressing against the wall surface, and it is possible to easily adsorb the adsorbing portions that have once come off to the original wall surface.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a moving body that moves along a wall surface with a plurality of suction portions on the wall surface and suctions the plurality of suction portions. In the one that is connected to the mechanism to obtain the suction force, a pressure opening / closing valve is formed between the suction portion and the suction mechanism, and the pressure opening / closing valve is urged outward by the pressing spring and the suction portion And a valve plate which is connected to the fixed wall in the extending direction of the adjustment chamber by a connecting rod and which is capable of opening and closing the communication passage between the suction mechanism and the adsorption portion. .

Alternatively, the plurality of suction portions may be fixed to a moving body that moves along the wall surface.

Further, a part of the plurality of suction portions may be a hand-held suction member that can be arbitrarily held by a worker who has boarded the moving body and sucked onto the wall surface.

Further, the hand-held suction member is provided with a suction body having a U-shaped cross section with a soft elastic suction ring provided on the outer periphery thereof, and a communication pipe having a communication passage communicating with the suction mechanism is connected to the suction body. An on-off valve that opens and closes the communication passage may be formed so as to be opened and closed from the outside.

Further, the valve plate of the pressure opening / closing valve may be formed as a mechanism that incompletely seals the suction part and the suction mechanism when closing.

Operation Since the present invention is configured as described above, the worker is suspended by a suspension mechanism such as a crane so that the moving body faces the wall surface, and an operator works on the rooftop of the building with the suction mechanism activated. If the user grasps and presses the moving body against the wall surface and presses the wall surface into contact with the adsorption part, a negative pressure is created in the adjustment chamber of the pressure on-off valve and in the communication passage, and the adjustment chamber resists the restoring force of the pressing spring due to the negative pressure. The valve body is contracted and the valve plate is opened, so that the suction portion is also in a negative pressure state and the moving body can be sucked onto the wall surface. Then, a part of the plurality of adsorbing parts comes into contact with the joints, steps, etc. of the wall surface to cause suction failure due to the introduction of outside air, and if separated from the wall surface, the outside air suddenly flows in from the separated adsorbing parts. The control chamber of the pressure on-off valve that communicates with the control chamber is brought to normal pressure, the control chamber is expanded by the restoring force of the pressing spring, and the fixed wall is pressed and moved outward. By this outward movement of the fixed wall, the valve plate connected to the fixed wall via the connecting rod is closed, and abrupt suction of outside air from the separated adsorbing portion is stopped, so that the other adsorbed on the wall surface. The adsorbing part of is not separated from the wall surface.

In addition, the suction part separated from the wall surface can be adsorbed to the wall surface again by an operator on the moving body moving the center of gravity of the moving body and pressing the separating / adsorbing part against the wall surface.

In order to perform even simpler suction, a hand-held suction member that is connected to a suction mechanism via a communication passage is used. In this method, the suction body of the hand-held suction member is pressed against the wall surface via the soft elastic suction ring, and the on-off valve of the hand-held suction member is opened.
If the negative pressure generated in the communication passage of the connecting pipe is also generated inside the suction body by the suction mechanism, the hand-held suction member can be sucked onto the wall surface. Then, the worker holds the hand-held suction member sucked on the wall surface by hand and pulls the moving body side of the suction portion separated from the wall surface toward the wall surface, so that the suction portion is easily sucked onto the wall surface and the moving body is held on the wall surface. Can be fixed to.

Also, if the valve plate of the pressure on-off valve is not completely sealed but incompletely sealed, a small amount of outside air is sucked from the adsorbing part opened through the valve plate closing part, and it is stronger than the restoring force of the pressing spring of the adjustment chamber. It is possible to maintain a negative pressure with a small force in the adsorption portion, the communication passage, the adjustment chamber, and the like. Therefore, when the opened adsorption part is adsorbed again on the wall surface, the negative pressure is easier to increase and a special valve plate opening / closing operation is performed, compared with the case where the valve plate is completely sealed and the communication passage and the adjustment chamber are in the normal pressure state. The valve plate of the pressure on-off valve can be quickly opened without performing the operation.

And a valve plate (10) that opens and closes the control chamber (8), and the adjusting chamber (8) is provided between the fixed wall (11) provided in the extension direction and the base (12) on the side of the communication passage (5). ), It is elastically urged in the outside direction and communicates with the suction portion (4) side of the communication passage (5), and the outer peripheral wall (14) is formed by a bellows so that it can be expanded and contracted. One end of the connecting rod (15) is fixed to the fixed wall (11) in the extending direction of the adjusting chamber (8), and the valve plate (10) is rotatably fixed to the other end of the connecting rod (15). At the same time, the valve plate (10) is attached to the suction mechanism (6).
One end of the valve plate (10) is axially fixed to the communication passage (5) connecting the suction portion (4) and the suction portion (4), and the other end of the valve plate (10) is formed in the communication passage (5). 16) is a butted communication passage (5), but the communication passage (5) is formed by the valve plate (10).
It is preferable that the closure is not completely sealed but has some breathability and is incompletely sealed.

Further, a part of the plurality of suction portions (4) is formed by a hand-held suction member (17) that can be arbitrarily held by a worker (2) who has boarded the moving body (1) and sucked onto the wall surface (3). Is also possible. As shown in FIG. 3, this hand-held suction member (17) is provided with a soft elastic suction ring (18) of neoprene sponge on its outer peripheral ring to form a suction member (20) having a U-shaped cross section. A connecting pipe (22) also serving as a handheld is connected to the communication port (21) of (20), and a communication passage (5) communicating with the suction mechanism (6) is connected to this connecting pipe (22). An opening / closing valve (23) for opening and closing the communication port (21) to which the connecting pipe (22) is connected is provided.
The end of the connecting shaft (24) having one end connected to 3) is projected outward from the connecting pipe (22) through the sleeve (25),
The connecting shaft (24) is pressed between the protruding end (26) and the sleeve (25) in the outward direction, and the spring (27) for closing the on-off valve (23) is positioned. Further, one end of the opening / closing lever (28) is connected to the projecting end portion (26) of the connecting shaft (24) by the connecting shaft (24).
By pressing 8), the on-off valve (23) is formed so as to be openable and closable from the outside via the connecting shaft (24). Further, the top plate (30) of the suction body (20) is provided with an introduction hole (31) capable of introducing a very small amount of outside air to introduce the outside air into the suction body (20) when the on-off valve (23) is closed. However, it can be detached from the wall surface (3).

When using the above-described structure for cleaning windows of buildings (32), repairing wall surfaces (3), etc., as shown in FIG. 5, it is suspended by a suspending mechanism (33) such as a crane and the moving body. While the suction mechanism (6) is operating with (1) facing the wall surface (3), the worker (2) is caught by the roof tree (34) of the building (32) and the moving body (1). Is pressed against the wall surface (3). When the wall surface (3) and the adsorption portion (4) are brought into pressure contact with each other as shown in FIG. 1, the inside of the adjustment chamber (8) of the pressure on-off valve (7) and the inside of the communication passage (5) are made into a negative pressure state, Since the adjusting chamber (8) contracts due to the negative pressure against the restoring force of the pressing bar (13), the connecting rod (15) presses the valve plate (10) and rotates from the connecting rod (15). As a result, the valve plate (10) is opened, so that the suction portion (4) is also in a negative pressure state and the moving body (1) can be sucked onto the wall surface (3). Then, when the wall surface (3) is moved, a part of the plurality of suction portions (4) is moved to the wall surface (3).
When it is separated from the wall surface (3) due to suction failure caused by the introduction of outside air due to contact with the joints, steps, etc., the separated adsorption part (4)
The outside air is suddenly introduced from the inside of the pressure chamber, and the pressure inside the adjusting chamber (8) of the pressure on-off valve (7) communicating with the adsorption portion (4) is brought to normal pressure, and the adjusting chamber (8) is pressed to restore the restoring force of the spring (13). Then, it is expanded as shown in FIG. 2 and the fixed wall (11) is pressed and moved outward. By this outward movement of the fixed wall (11),
Since the valve plate (10) connected to the fixed wall (11) through the connecting rod (15) is closed to stop the sudden suction of the outside air from the adsorbed portion (4) which has been separated, the wall surface (3) is closed. The suction force of the other suction portion (4) that has been sucked is eliminated and is not separated from the wall surface (3).

Moreover, in order to make the wall surface (3) again adsorb the suction portion (4) separated from the wall surface (3), the worker (2) on the mobile body (1) moves the center of gravity of the mobile body (1). This can be done by pressing the separating / adsorbing part (4) against the wall surface (3).

Further, for more simple suction, a hand-held suction member (17) connected to a suction mechanism (6) through a communication passage (5) as shown in FIG. 3 is used. In this method, the suction body (20) of the hand-held suction member (17) is pressed against the wall surface (3) through the soft elastic suction ring (18), and the spring (27).
The opening / closing lever (28) is pressed with a force larger than the pressing force of (1), the connecting shaft (24) is operated inward, the opening / closing valve (23) of the hand-held suction member (17) is opened, and the suction mechanism ( If the negative pressure generated in the communication passage (5) of the connecting pipe (22) by 6) is also generated in the suction body (20), the hand-held suction member (17) is sucked onto the wall surface (3). Can be made. Then, the worker (2) holds the hand-held suction member (17) sucked on the wall surface (3) by hand, and attaches the suction portion (4) side of the moving body (1) separated from the wall surface (3). If it is pulled in the direction of the wall surface (3), the suction part (4) can be easily
Can be adsorbed on the wall surface (3) to fix the moving body (1) to the wall surface (3). Further, in order to separate the hand-held suction member (17) from the wall surface (3), the connecting shaft (24) is slid outward by the restoring force of the spring (27) to open the on-off valve (2).
3) is closed, suction from the communication passage (5) is stopped, and the negative pressure generated inside the suction body (20) is also reduced by suction body (2).
0) through the introduction hole (31) or the valve seat (16), the gap between the adsorption ring (18) and the like, the inside pressure of the suction body (20) becomes normal pressure, and the hand-held suction member (17) is It can be separated from the wall surface (3).

Further, if the valve plate (10) of the pressure on-off valve (7) is not completely sealed but incompletely sealed, a small amount of outside air is sucked from the adsorption part (4) opened through the valve plate (10) closing part. Then, a negative pressure having a force smaller than the restoring force of the pressing bar (13) of the adjustment chamber (8) is applied to the adsorption chamber (4), the communication passage (5), and the adjustment chamber (8).
It is possible to keep it inside. Therefore, when the opened adsorption part (4) is adsorbed again on the wall surface (3), the valve plate (10) is completely sealed and the inside of the communication passage (5) and the adjustment chamber (8) are closed.
Compared with the case where the inside is in a normal pressure state, the negative pressure of the adsorbing part (4) is easily increased, and the valve plate (10) of the pressure on-off valve (7) can be quickly opened without performing a special valve plate (10) opening / closing operation. The valve can be opened.

Further, in the embodiment shown in FIG. 1, the suction force of all the suction portions (4) provided in the moving body (1) is generated by one suction mechanism (6), but another different embodiment. If the suction mechanism (6) has a small capacity, a plurality of suction portions (4) are connected to the suction mechanism (6), but all suction portions (4) provided in the moving body (1) are connected. Instead of generating a suction force, as shown in FIG. 4, a plurality of suction mechanisms (6) connected to a plurality of suction portions (4) may be provided in the moving body (1).

EFFECTS OF THE INVENTION Since the present invention is configured as described above, a window wiping worker of a building, a moving body on which a repair worker for a wall is placed, a moving body equipped with a window cleaning device by an unmanned robot, and a fire extinguisher are mounted. When the wall surface moving body is provided with a plurality of suction portions for the wall surface, and the plurality of suction portions are connected to one suction mechanism, the suction portions contact the joints, steps, etc. of the wall surface, Even if the adsorption part is separated from the wall surface, there is no separation of other adsorbing parts that are adsorbing due to the presence of the pressure on-off valve.
Enables safe and stable work. Also, when adsorbing one or a plurality of separated adsorption parts to the wall surface again,
It is possible to press the suction portions one by one against the wall surface. In addition, a single suction mechanism enables stable suction at a low cost while using a plurality of suction portions.

Further, if one of the suction portions is a hand-held suction portion, this can be performed very easily when the separated suction portion is sucked again onto a wall surface without a clue.
