て負圧領域を規定するものである。The above-mentioned conventional device has the following problems to be solved. First
The problem is that the suction force of the suction transfer device is proportional to the area of the negative pressure region at the same degree of vacuum, and therefore the suction force becomes very large when the negative pressure region is large, and the object surface is In the case of a thin steel plate, the steel plate is bent by the action of the suction force and is damaged. Further, when the surface of the object is covered with a material such as mortar, the material such as mortar is peeled off due to the action of the suction force. In such a case, it is necessary to reduce the area of the negative pressure region of the suction moving device. Next, when the surface of the object is covered with a fiber or a porous material, a measure is taken to prevent the material from being peeled off by the action of the adsorption force as in the case of the first problem. There is a case where it is desired to suction and clean a substance such as dirt that has entered the porous portion of the object surface, but the second problem is that when the suction air volume of the vacuum pump used for suction cleaning is limited,
If the volume of the voids in the porous portion is large, the velocity of the outside air sucked through the voids is reduced, and thus the suction cleaning ability is reduced. In such a case, it is necessary to shorten the length of the portion where the seal member blocks the outside air as much as possible.
The seal member of the suction moving device is mounted on the main casing, and its free end is brought into contact with the surface of the object to prevent the inflow of outside air as much as possible, and thus the seal member and the main casing and the surface of the object are Cooperate with each other to define the negative pressure region.

題を述べた。Therefore, the technical problem to be solved by the present invention is as follows. A first technical problem to be solved is to provide an adsorption transfer device having an annular negative pressure region in order to reduce the area of the negative pressure region of the device. A second technical problem to be solved is that the outer seal member arranged on the outer peripheral portion of the annular negative pressure region has a free end portion for blocking outside air by closely contacting with the surface of the object, while the inner seal member arranged on the inner peripheral portion is arranged. Although the seal member has a free end portion that comes into close contact with the surface of the object, the inner seal member has a shape that covers the entire space inside the negative pressure region of the ring, so that the outside air is blocked. An object of the present invention is to provide a suction movement device including an outer seal member and an inner seal member. The third technical problem is the same with respect to the pressure of the space inside the annular negative pressure region, that is, the pressure for pressing the inner seal member against the object surface, as compared with the pressure of the fluid surrounding the device. Alternatively, the contact pressure between the inner seal member and the surface of the object is reduced by maintaining the pressure at a low pressure and higher than the pressure in the annular negative pressure region, and thus the inner seal member and the surface of the object are reduced. It is an object of the present invention to provide an adsorption movement device that can move smoothly along the surface of an object because the contact pressure of the object is reduced. A fourth technical problem to be solved is to provide an adsorption movement device provided with a nozzle port of a rotary nozzle unit for ejecting a fluid such as high-pressure water or compressed air into a negative pressure region formed in an annular shape. . In the above, in the device that is attracted to the surface of an object and moves along the surface of the object due to the generation of negative pressure inside, the problems of the prior art are pointed out, and the problems to be solved by the present invention are described. .

水または圧縮空気などの流体を噴出することができる。As a first action, in the device of the present invention, when the pressure in the first region is maintained at a pressure lower than the pressure of the surrounding fluid in the device, the negative pressure in the first region causes the action. The device adsorbs to the surface of the object. In this case, since the shape of the negative pressure area is annular, the area of the negative pressure area is smaller than that in the case of a circular shape. That is, comparing the case where the shape of the negative pressure region is circular and the case where it is circular, if the diameter of the outer circumference of the annular shape and the diameter of the outer circumference of the circular shape are the same, the area is more circular small. Therefore, it is possible to prevent the material such as mortar from peeling off from the surface of the object due to the action of the suction force. As a second action, in the device of the present invention, the outer seal member arranged on the outer peripheral portion of the annular negative pressure region has a free end portion for blocking outside air by closely contacting with the object surface, while the inner peripheral portion has Although the inner seal member to be arranged has a free end portion that comes into close contact with the object surface,
The inner seal member has a function of blocking the outside air by forming a shape that entirely covers the space inside the annular negative pressure region. The pressure in the second region defined by the cooperation of the inner cylindrical partition and the inner sealing member is maintained at the same pressure as or slightly lower than the pressure of the surrounding fluid of the device. As described above, since the outside air does not flow from the second region into the first region, the suction air volume of the vacuum pump used for suction cleaning is limited, and the volume of the voids in the porous portion of the object surface is limited. In the case of a large value, the decrease in the velocity of the outside air sucked through the gap is prevented as much as possible, and thus the decrease in the suction cleaning ability is prevented as much as possible. Thirdly, the pressure of the space inside the annular negative pressure region, that is, the pressure for pressing the inner seal member against the object surface is the same as or lower than the pressure of the fluid surrounding the device. The contact pressure between the inner seal member and the object surface is reduced by maintaining the pressure higher than the pressure in the annular negative pressure region, and thus the contact pressure between the inner seal member and the object surface. Is reduced so that the device can move smoothly along the object surface. As a fourth action, since the nozzle port of the rotary nozzle unit is provided in the negative pressure region formed in the ring shape, a fluid such as high pressure water or compressed air is ejected toward the object surface in the negative pressure region. can do.

When the negative pressure generating means (not shown) is activated, a fluid such as the atmosphere inside the first region 11 is discharged to the outside through the connecting pipe portion 211 and the suction hose (not shown), and the first region 11 is discharged. The pressure is reduced as required. Thus, when the first region 11 is depressurized, the pressure of a fluid such as the atmosphere surrounding the device causes the outer cylindrical partition 21 to move toward the object surface 1 due to the fluid pressure difference between the inside and outside of the first region 11. To the four wheels 4
1 is transmitted to the object surface 1, and the apparatus is thus attracted to the object surface 1. When the wheels 41 are rotationally driven by a driving means such as a geared motor (not shown), the apparatus moves along the object surface 1. To do. The first area 1
When the pressure inside 1 is maintained at the desired pressure, the pressure of the fluid surrounding the device, such as the atmosphere, is increased by the free end of the outer seal member 31 due to the fluid pressure difference inside and outside the first region 11. Section and the free end of the inner seal member 32 are pressed in the direction of the object surface 1 and thus prevent the surrounding fluid from flowing into the first region 11 as much as possible. Regarding the flow path of the surrounding fluid, the surrounding fluid passes through the slight gap between the free end of the outer sealing member 31 and the object surface 1 to the first region 1
1, then passes through the connecting pipe portion 211 and the suction hose (not shown) to reach the negative pressure generating means (not shown). The high-pressure water or compressed air ejected from the rotating nozzle 7 collides with the object surface 1 to remove substances such as dirt adhering to the object surface 1, and then rides on the flow of the surrounding fluid to generate negative pressure ( (Not shown).

に移動することができる。The effects of the above-described apparatus of the preferred embodiment of the present invention will be described. Since the suction force of the suction moving device is proportional to the area of the negative pressure region, the suction force becomes very large when the area of the negative pressure region is large, and the steel sheet has a suction force when the object surface is a thin steel plate. The action will bend and cause damage. Further, when the surface of the object is covered with a material such as mortar, the material such as mortar is peeled off due to the action of the suction force. In such a case, it becomes necessary to reduce the area of the negative pressure region of the adsorption transfer device. The apparatus of the preferred embodiment of the present invention is provided with a first area 11 which is an annular negative pressure area in order to reduce the area of the negative pressure area of the apparatus. Comparing the case where the shape of the negative pressure region is annular and the case where it is circular, if the diameter of the outer circumference of the annular shape is the same as the diameter of the outer circumference of the circular shape, the area is smaller when the shape is annular. Since the rotating diameter of the nozzle 7 is sufficiently large, the reduction of the area of the negative pressure region does not hinder the work efficiency. Next, a preferred embodiment of the present invention in the case where the object surface 1 is made of a fiber or a porous material having a large void volume and it is desired to suction and clean a substance such as dirt that has entered the void portion of the object surface 1. The effect of the device will be described. Since the inner seal member 32 of the preferred embodiment device covers all of the object surface 1 inside the annular negative pressure area, outside air from the negative pressure area from the negative pressure area or first area 11 Does not flow into the interior of. Therefore, even when the suction air volume of the vacuum pump used for suction cleaning is limited and the volume of the void in the porous portion of the object surface 1 is large, the velocity of the outside air sucked through the void does not decrease. It is prevented as much as possible, so that the reduction in suction cleaning ability is prevented as much as possible. Next, in the apparatus of the preferred embodiment of the present invention, since the nozzle opening of the rotating nozzle 7 is provided in the first region 11 formed in an annular shape, the object surface 1 is formed on the object surface 1 in the first region 11. A fluid such as high pressure water or compressed air can be jetted. In addition,
In the apparatus of the preferred embodiment of the present invention, the connecting pipe portion 51 is connected to a negative pressure regulating valve (not shown) and a negative pressure generating means (not shown) via a hose (not shown), Two
It is also possible to keep the pressure in region 12 below the pressure of the fluid surrounding the device and above the pressure in first region 11. In this case, the contact pressure between the inner seal member 32 and the object surface 1 is reduced. Thus, the frictional resistance between the inner seal member 32 and the object surface 1 is reduced so that the apparatus of the preferred embodiment of the present invention can move smoothly along the object surface 1.
