BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall moving device for inspecting a wall finishing material while moving along an outer wall of a building.

[0002]

2. Description of the Related Art There is a wall moving device as an automatic device for inspecting a condition of a finishing material on an outer wall surface of a building, or for performing painting or repair. As the wall moving device, there is a device which is self-propelled while adsorbing on an outer wall surface by vacuum suction as developed by the present applicant, or a gondola type device in which a main body is suspended at a tip of a hanging rope.

The former has a structure in which a large number of suction disks are arranged in a caterpillar type on both sides of a main body, and the suction disks are sequentially moved on the wall surface while being suctioned to the wall surface. On the other hand, in the latter case, a fan propeller is provided on the back of the main body to prevent the main body of the device from separating from the outer wall surface, and the main body is made use of the thrust of the propeller or a vacuum suction force generated inside the main body by blowing air. This is to adhere to the outer wall. In this case, there is a device that changes the direction of air flow of the fan propeller and moves the suspended device along the outer wall surface to correct a lateral displacement due to the influence of wind or the like. The prior art described above is disclosed in Japanese Utility Model Publication No. 53-1922 and Japanese Patent Application Laid-Open No. 60-73966.

[0004]

However, in the former self-propelled structure using the suction disk, when the finishing material has irregularities such as a brick tile, the vacuum suction force is weak, and the driving mechanism for self-propelled operation is used. Has the drawback that its own weight is heavy and handling is difficult.

[0005] In the latter rope hanging method, both the vertical movement and the lateral movement must be performed by operating the hanging rope, and the moving operation is troublesome.
The work of correcting the position of the main body when a cross wind blows was also troublesome.

The present invention has been made to solve the above problems, and has as its object to provide a wall which can be configured to be lightweight and compact, can be easily moved, and can be easily adjusted in position when wind or the like blows. It is an object to provide a mobile device.

[0007]

In order to achieve the above object, the present invention provides a rope which is vertically stretched or suspended along an outer wall of a building, and which can be suspended in the rope and moved in a lateral direction. Wall moving device comprising a moving device body, the moving device body, a pair of rotatable fan propeller,
Driving means for separately driving each fan propeller and control means for controlling the driving of each driving means, wherein the fan propeller has a rotation axis on an axis orthogonal to the outer wall surface in the same horizontal plane. The control device moves the main body of the moving device in a desired direction by changing the number of rotations of each driving device. .

[0008]

The rotation speed of one fan propeller is made higher or lower than the rotation speed of the other fan propeller in consideration of the wind direction when the rotation speed of the pair of fan propellers is the same or the wind is blowing. By doing so, it is possible to maintain the balance state of the thrust in the left-right direction and stop the moving device body while adsorbing the main body to the outer wall surface. By positively unbalancing the rotational speeds of the pair of fan propellers, the moving device main body can be moved by a desired amount in a desired direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a longitudinal sectional view of a wall moving apparatus according to the present embodiment, and FIG. 2 is a transverse sectional view. A wire rope 3 is stretched vertically along an outer wall surface 1 of a building.
The moving device main body 5 is provided so as to be able to move up and down along.
The upper end of the wire rope 3 is attached to a moving mechanism 9 that can move freely along a rail 7 provided horizontally at the top (roof) of the building.

The apparatus main body 5 has a cover 1 forming a part of a spherical surface on a back surface of a flat case 11 facing the outer wall surface 1.
3 is covered. The case 11 is provided with a plurality of caster-type wheels 15 and is in contact with the outer wall surface 1. A duct 17 for rectifying the air flow of a fan propeller, which will be described later, is opened on the back surface of the cover 13, and a ladder 19 is provided in the duct 17.

An insertion hole 21 through which the wire rope 3 is inserted is formed in a vertical direction of the case 11. A plurality of guide rollers 23 are attached to the inserted wire rope 3.
Contact the drive roller 25 and the pinch roller 27
Pressed by. By the forward and reverse rotation of the drive motor 29 for rotating the drive roller 25, the apparatus main body can be moved up and down along the wire rope.

In the case 11, a pair of fan propellers 31 are provided. Fan propeller 3
The positions of the rotation shafts 1 and 31 are fixed such that their rotation axes have a C-shape having a predetermined angle symmetrical with respect to an axis perpendicular to the outer wall surface in the same horizontal plane. The fan propeller 31 is rotated by driving a fan motor (drive unit) 33 controlled by a control unit (not shown). The angle of the fan propeller 31 with respect to the moving device main body 5 may be an optimal value set in advance in consideration of the weight of the entire moving device main body 5, the working environment, and the like (for example, 30 to 75 degrees with respect to an axis perpendicular to the outer wall surface). Degree). The air blown by each fan propeller 31 is
7, and the ladder 19 can increase or decrease the thrust in the contact direction or the lateral direction. In addition,
In the present embodiment, the angle of the rudder 19 can also be changed by a control servo motor (not shown). The drive of the drive motor 29, the fan motor 33, and the like is controlled by control means (not shown). A movement signal from an operation unit (not shown) is transmitted to the control unit by remote control.

In addition, devices for inspecting, painting or repairing the outer wall surface 1 are arranged inside the case 11 according to the intended use, but the description of these devices is omitted. Further, cables for power supply, data collection and remote control are drawn out from the device main body 5, or a wireless transmitter or the like is built in, so that traveling adjustment of the device main body 5, data collection, etc. can be controlled at a remote position. However, these cables and wireless transmitters are not shown.

In the above configuration, the apparatus main body 5 is vertically moved by rotating the drive roller 25 by the drive motor 29 to move up and down along the wire rope 3. The movement in the left-right direction is performed by the moving mechanism 9 provided at the top of the building, if the moving mechanism 9 has a function of performing the lateral movement. However, the moving mechanism 9 itself may not be provided with a function of moving in the lateral direction, and may be moved in the lateral direction only by the fan propeller 31 of the moving device main body 5. In other words, when the fan motors 33 and 33 have the same rotation speed, when there is no wind, the moving device main body 5 can be stopped in a state where it is attracted to the outer wall surface. And
By reducing the rotational speed of one of the fan propellers 31 (for example, the right side in the figure) with respect to the other, or by completely cutting off the current, the driving force of the left and right fan motors 33 is positively unbalanced so that the lateral Fine adjustment of the positioning in the direction can be performed. Thus, the moving device main body 5 moves in the lateral direction while moving like a pendulum while being suspended from the moving mechanism 9 by the wire rope 3. In this case, by controlling the angle of the rudder 19, the amount of movement of the moving device main body 5 in the lateral direction can be finely adjusted. This makes it possible to smoothly move in the lateral direction (see FIGS. 2B and 3B). In this way, the moving mechanism 9 itself does not have a special lateral moving function, so that the size and weight can be reduced, and the cost of the entire apparatus can be reduced.

Further, when the apparatus main body 5 is displaced leftward in the figure due to the influence of the cross wind 37 (FIG. 3B).
As in the case of the previous movement, the rotational displacement of the pair of right and left fan propellers 31, 31 can be unbalanced to immediately correct the positional deviation (FIG. 7A). In this case, the position correction by the cross wind may be performed manually, or the moving device body may be provided with a wind detection unit and a wind direction detection unit or a displacement detection unit, and may be automatically performed based on the detection results. .

The duct 17 need not be provided with a ladder 19. That is, if the capacity of the fan motor 33 can be sufficiently increased, the thrust can be increased or decreased without the rudder 19.

In the above embodiment, the moving mechanism 9 is used.
Although the moving mechanism 9 has been described as not having a moving function itself, in other embodiments, the moving mechanism 9 has a moving function. It is also possible to use the fan propeller 19 only for correcting the lateral displacement due to the above.

Furthermore, without providing the moving mechanism 9, a rope is laid laterally on the top of the building, and the horizontal rope is suspended at the upper end of the rope that suspends the moving device body 5. A configuration in which only a ring is provided may be employed. In this case, the moving device main body 5 can move in the lateral direction only by the rotation of the fan propeller 31, and the movement is guided by the lateral rope.

[0020]

As described above, according to the wall moving apparatus of the present invention, the moving apparatus main body can be moved in the horizontal direction by positively unbalancing the rotational speeds of the pair of fan propellers arranged in a C shape. Positioning can be performed. For this reason, fine adjustment of the position in the lateral direction and lateral displacement due to the influence of wind or the like can be easily corrected.
