Description

[Detailed Description of the Invention] Industrial Application Field The present invention is capable of moving a gondola carrying a building window cleaner, wall repair worker, etc. while stably adhering and fixing it to a building's window glass, wall surface, etc. This invention relates to a wall suction and movement device that does this.

BACKGROUND OF THE INVENTION Conventionally, gondolas for transporting building window cleaners, wall repair workers, etc., while adsorbing and fixing them to building window glass, walls, etc., have been proposed, for example, in Japanese Patent Application Laid-open No. 1983-1999. 2
There is an invention described in Publication No. 68784, but in this invention, the annular seal body for maintaining airtightness moves while sliding on the wall surface, so the seal body is made of a hard rough surface such as brick, mortar, or concrete. On the wall of the building where
This has the disadvantage that the annular seal body wears out in a very short period of time, rendering it unable to perform its sealing function.

In order to eliminate this drawback, Japanese Patent Application Laid-Open No. 62-25528
There is also an invention described in Publication No. 8 in which an adsorbent is placed on the inner surface of a belt-shaped running belt, but this invention has a plurality of adsorption openings separated by a separation wall, so this separation is difficult. When the wall passes through the suction hole formed in the running zone, it is closed, reducing the suction ability of this part and weakening the suction force to the wall of the device, making it possible to stably attach it to the wall of the gondola, etc. It had the disadvantage that it was difficult to maintain it properly.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems.When moving along the wall of a building using a gondola, etc., the seal part of the traveling belt that sticks to the wall The purpose is to avoid wear, and to always obtain stable adhesion force to walls, etc., without changing even when the running zone moves.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a running belt made of a soft elastic material in which a plurality of adsorption chambers each having an adsorption opening on the wall surface are divided at appropriate intervals by partition walls. is formed into a ring shape, and an annular sliding belt made of a material with good surface sliding properties is fixed to the inner surface of this running belt. To,
A single annular suction opening made of a sealing member made of a soft elastic material is brought into airtight and slidable contact to form a suction with a U-shaped cross section. A vacuum hose is connected to create a negative pressure state, and a running roller is rotatably connected and fixed via a rotating shaft to a fixed frame that is provided without interlocking with the running belt and the sliding belt. The running roller receives the adsorption pressure of the adsorbent, prevents the adsorbent from strongly adhering to the running belt via the sliding belt, and presses the seal member against the sliding surface with enough contact pressure to maintain airtightness. It may be something that

Further, a support roller may be formed inside the suction body, and by abutting the support roller against the sliding belt, the sliding belt and the running belt may be prevented from being bent into the suction chamber.

In addition, the sealing member is made by inserting a resilient material made of a soft elastic material into a ring frame with a U-shaped cross section made of a hard material, allowing it to slide for 1 m, and sliding it on the sliding surface of the resilient member that comes into contact with the sliding belt. It may be a fixed sliding piece with good mobility.

The sealing member is made of a hard material with a resilient material made of a soft elastic material fixedly inserted into an annular inner frame with a U-shaped cross section, and in contact with the sliding belt. An adjustment piece made of a soft elastic material may be inserted slidably into the annular frame and between the upper end of the annular inner frame and the annular frame.

Function Although the present invention is constructed as described above, in order to use it, the pulling row 1 for suspending and moving the device is fixed to the fixed frame of the device, and at the same time, a person [m Connect and fix the gondola for riding. Then, by pressing the adsorption opening of the adsorption chamber facing the wall of a building, etc., and operating a pressure reducing device such as a vacuum pump connected to a vacuum hose, the pressure inside the adsorbent is reduced to a negative pressure state. This negative pressure state reduces the pressure inside the adsorption chamber of the running belt through the ventilation hole of the sliding belt, so the running belt is attracted to the building wall, glass surface, etc., and the gondola connected to the fixed frame swings like a pendulum. It does not shake or separate from the wall surface, making it possible to securely attach it to the wall surface. In addition, since this suction is performed by connecting - suction openings to a plurality of vents, as in the past, the separation wall of the suction openings passes through the suction vents formed in the running zone. There is no need to close this, reduce the suction ability of this part, weaken the suction force to the wall of the device, and make it difficult to stably hold the wall of the gondola or the like.

In addition, if this adsorption simply reduces the pressure inside the adsorbent,
The suction force of the reduced pressure causes the adsorbent to bite into the running belt, making it difficult to move the running belt. However, since the adsorbing member is connected to the running roller through a fixed frame, the roller is easily moved by rotation. , the above-mentioned biting force of the adsorbent is transmitted, the adsorbent does not bite into the running belt, and only the sealing member contacts the sliding belt with enough pressure to maintain airtightness, and only the depressurizing effect inside the adsorbent is applied to the running belt. The pressure is transmitted to the reduced pressure chamber, and a reliable reduced pressure adsorption effect can be obtained.

Then, when the traction lobe is pulled upward while the traveling belt is attracted, the fixed frame moves upward, and when it is loosened, the fixed frame moves downward under its own weight. During this movement, the adsorbent and running roller, which are connected and fixed to the fixed frame, are pulled, and the sealing member slides on the easily sliding surface of the sliding belt while maintaining airtightness, but the running belt slides on the wall surface. Since the running roller only rolls as the position of the running roller moves, there is no wear on the running belt made of a soft elastic material, allowing stable use over a long period of time.

In addition, by providing a plurality of running rollers at appropriate intervals on the inner periphery of the belt at both ends of the running belt in the moving direction, the forming interval of the running belt can be increased to a certain size or more for insertion of adsorbents, etc. Even in the case where one running roller is installed at both ends in the moving direction, the area occupied by the running roller can be made smaller, and the device can be made more compact.

Further, by forming a support roller inside the suction body and abutting this support roller against the sliding belt, it is possible to prevent the sliding belt and the running belt from being bent in accordance with the reduced pressure in the suction chamber.

In addition, the sealing member is made of a soft elastic material and is slidably inserted into an annular frame with a U-shaped cross section made of a hard material. If a sliding piece with good mobility is fixed, the contact pressure of the elastic material to the sliding belt as the vacuum increases or decreases will be automatically adjusted such that the contact pressure of the elastic material against the sliding belt increases as the vacuum increases, and becomes weaker as the vacuum weakens. The presence of the piece not only improves sliding performance with the sliding belt, but also prevents the elastic material from being pulled out from the annular frame, which occurs when the medium friction force is large.

In addition, the sealing member is fixedly inserted into an annular inner frame made of a hard material and having a U-shaped cross section, and a resilient material made of a soft elastic material is fixedly inserted into the sealing member so as to be in contact with the sliding belt. Assuming that the elastic material is slidably inserted into the annular frame and an adjustment piece made of soft elastic material is inserted between the upper end of the annular inner frame and the annular frame, the dimensions of the elastic material must be precisely adjusted to correspond to the annular frame. Even if it is not formed, the position of the annular inner frame within the annular frame can be adjusted as desired within the adjustment range of the adjustment piece, making it possible to absorb some manufacturing errors in the sealing member.
