Description

Wall work device and method

The present disclosure relates to an apparatus and method for performing work such as inspection and painting on walls.

Conventionally, when performing some work (painting, assembling machines, inspection, etc.) on the walls of buildings, other structures, natural objects, etc., scaffolding is built along the walls so that people can come and go. It is common for a person to climb a scaffold and perform the above work. However, it takes a considerable amount of time and effort and cost to assemble a scaffold having sufficient strength for a person to safely work, and the work itself by hand also takes time and cost.

Therefore, it has been proposed to replace such work with a small flying device, and it is being put into practical use (for example, see Patent Documents 1 and 2 below).

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

1 to 3 show an example (first embodiment) of the form of the wall working device in the present disclosure. The wall working device 1 of the first embodiment includes a traveling body 2 and a pair of lifting support devices 3. While traveling the traveling body 2 along the wall surface W to be worked, the left and right lifting support devices The running body 2 is supported by a support operation cable 4 extending from the 3, and the position of the running body 2 is operated.

In this specification, the term “wall surface” refers to the outer surface of a building or a wall as a partition, a fence that separates an outdoor area, an inner wall of a machine or facility such as a power plant furnace, or a cliff in a natural structure. A plane, or any other plane oriented along a vertical plane. A "surface oriented along a vertical plane" does not only refer to a plane that is strictly perpendicular to the direction of gravity, but may also be a curved surface or inclined to some extent. Any planar structure that can be sensuously recognized as a wall surface or a surface similar thereto by humans can correspond to the "wall surface" in this specification.

The traveling body 2 is provided with wheels 2b as traveling portions at the four corners of a main body 2a formed by combining rod-shaped structural members in a rectangular shape. As shown in FIG. can run. Each wheel 2b is, for example, a ball caster attached to the back side of the running body 2 (here, the side facing the wall surface W with respect to the running body 2 is called the "back side", and the opposite side is called the "front side"). By rotating the wheels 2b, the traveling body 2 can freely travel in any direction along the wall surface. It should be noted that the term "running" as used in this specification does not only refer to running on wheels, but generally means moving along a wall surface. That is, in the implementation of the wall working apparatus, the mechanism for traveling is not limited to wheels as shown here when the traveling body travels along the wall surface. Further, as a specific configuration of the main body 2a and the traveling portion (wheels) 2b, various forms other than those described here can be adopted as long as the work can be performed without hindrance as will be described later.

A propeller 2c is provided on the front side of the running body 2 to generate a pressing force that presses the entire running body 2 toward the wall surface W. The propeller 2c is designed to blow air from the running body 2 to the front side by rotation, and the entire running body 2 is pushed to the back side by the reaction, thereby holding the running body 2 against the wall surface W. there is

Here, from the viewpoint of improving the responsiveness regarding the operation of the traveling body 2, it is particularly preferable to adopt a so-called variable pitch propeller as the propeller 2c. A variable-pitch propeller is a propeller that can freely change the pitch, and can change the magnitude and direction of thrust while keeping the rotation direction and rotation speed constant. That is, when the propeller 2c is a variable pitch propeller, the propeller 2c can change the magnitude of the pressing force against the wall surface W in various ways, and can also set the pressing force to zero while rotating in the same direction. Furthermore, a negative pressing force (a force directed away from the wall surface W) can also be generated.

In the case of the first embodiment, the mounting positions of the two support operation cables 4 on the running body 2 are the upper right and upper left of the main body 2a. For example, it is possible to connect two support operation ropes 4 to one point on the upper part of the main body 2a to suspend and support the running body 2, but in such a case, the running body 2 moves along the wall surface W As a result, there is a possibility that the traveling body 2 swings in the horizontal direction toward the wall surface W below the support point of the support operation cable 4 . Therefore, as shown in FIG. 1, if the support operation ropes 4 are connected to two different points and the running body 2 is suspended by the tension from the two points, the movement of the running body 2 is restrained at the two points. , thereby suppressing the occurrence of shaking in the horizontal direction.

Further, in the case of the first embodiment, the traveling body 2 is provided with a suction portion 5 for suctioning the wall surface W. As the suction unit 5, for example, the same device as a device sold under the name of "vacuum gripper", "vacuum suction gripper", "vacuum suction pad", or "suction lifter" is used, or a principle common to these devices is used. equipment can be used. That is, the suction unit 5 is configured as an air suction device that sucks air between itself and the wall surface W to generate a negative pressure, whereby the entire traveling body 2 to which the suction unit 5 is attached is held on the wall surface W. do. Alternatively, when a structure made of a magnetic material such as iron (for example, a furnace wall of a thermal power plant, etc.) is assumed as the wall surface W to be worked, the adsorption unit 5 may be configured as an electromagnetic adsorption device. . That is, the attraction part 5 is provided with an electromagnet, and when the electromagnet is energized, the wall surface W, which is a magnetic material, is attracted by an electromagnetic force. In addition, devices based on various mechanisms and principles can be employed as the adsorption unit 5 as long as they can be appropriately adsorbed to the wall surface W, such as a type that adsorbs to the wall surface W by electrostatic force.

If the adsorption unit 5 is a pneumatic adsorption device, a separate pump or tube is required for sucking air. , depending on the required attraction force, a separate power supply device and power cable for supplying power from the outside are required. In the wall working device 1 of the first embodiment, devices such as a pump and a power supply device used for the operation of the suction unit 5 can be loaded in the basket 3b as suction-related devices 5a. Further, the suction unit 5 mounted on the traveling body 2 and the suction-related device 5a loaded on the basket 3b can be connected by a tube as a connecting cable 6 or a power cable. The connecting cable 6 is a cable, a hose, a tube, or a bundle thereof that connects the equipment mounted on the traveling body 2 and the equipment loaded on the basket 3b.

Thus, in the first embodiment, the traveling body 2 is held against the wall surface W by both the pressing force of the propeller 2c and the adsorption force of the adsorption portion 5. As shown in FIG. In implementing the wall working apparatus, the traveling body may be provided with either the propeller or the suction unit depending on conditions such as the weight of equipment mounted on the traveling body.

In addition, working equipment 7 for working on the wall surface W is mounted on the traveling body 2 . The specific configuration of the work device 7 varies depending on the content of the work. 1, the working equipment 7 is a camera or other measuring equipment for acquiring an image of the wall surface W, and when assembling some parts or devices to the wall surface W, the working equipment 7 is a tool or the like. . The work equipment 7 is provided with a power cable for power supply, data acquired by the work equipment 7, and operation signals to be input to the work equipment 7, depending on the configuration of the work equipment 7 and the content of the work. A communication cable, a supply tube for supplying paint, and the like are connected as a connecting cable 6 .

The elevating support device 3 includes support columns 3a installed along the wall surface W on the left and right sides of the traveling body 2, and a basket 3b as an elevating body that moves up and down along the support columns 3a. A winder or the like (not shown) is installed at an appropriate position on the support column 3a, and the operation of the winder or the like allows the basket 3b to move up and down along the support column 3a. Although the basket 3b is exemplified here as the elevating body, the structure of the elevating body is not limited to this. For example, the elevating body may be configured as a platform that elevates along the support column 3a. Further, the mechanism for raising and lowering the elevating body is not limited to the winding machine, and for example, a self-elevating elevating device may be employed.

As the lifting support device 3, for example, devices similar to various devices sold as devices for scaffold work can be used. For example, the applicant of the present application has developed a "power mast" (trade name) and a "power lift" (trade name) that move a scaffold for wall work up and down along a support column, and support a basket for unloading on the scaffold for wall work. We sell a device called "Power Climber" (trade name) that moves up and down along a pillar, and these devices can be used as they are or partially modified to be used as a lifting support device for wall work equipment.

A hoist 8 as a payout device for the support operation ropes 4 that operate the traveling body 2 via the support operation ropes 4 is loaded on the basket 3b. The support operation rope 4 is a wire rope that supports the traveling body 2, and the hoist 8 is a device that pays out and winds up the support operation rope 4. As shown in FIG. The tips of a pair of support operation cords 4 drawn out from the positions of the left and right baskets 3b are connected to the running body 2, thereby supporting the running body 2 from the left and right and manipulating its position. A motor (not shown) for powering the hoist 8 is also loaded on the basket 3b. The hoisting machine 8 and the motor (not shown) may be installed at a position other than the basket 3b. It is convenient to load the hoist 8 in the basket 3b.

In addition, equipment (work-related equipment 7a) used in relation to work by the work equipment 7 mounted on the traveling body 2 is loaded in the basket 3b. For example, the work-related equipment 7a corresponds to the power supply of the work equipment 7, the communication cable when the work equipment 7 is operated by wire, and the paint tank when the work equipment 7 is a nozzle for painting. do. A connection cable 6 connects the work-related equipment 7a loaded in the basket 3b and the work equipment 7. As shown in FIG.

In addition, the wall working device 1 is provided with a height sensor 13 for measuring the height of the basket 3b provided in the lifting support device 3. The height sensor 13 is, for example, a laser ranging sensor. In the case of the first embodiment, the height sensor 13 is provided at the height of the ground where the left and right lifting support devices 3 are installed in FIG. By irradiating light and detecting reflected light from the basket 3b, the height of the basket 3b can be grasped. Incidentally, the height sensor 13 may be attached to the side of the basket 3b instead of the height of the ground.

Also, at least one of the baskets 3b (in the case of the first embodiment, the basket 3b on the left side as you face it) is provided with a distance sensor 9 for detecting the distance to the other basket 3b. The distance sensor 9 is, for example, a laser-type distance measuring sensor. The distance between the

baskets

3b, 3b attached to the lifting support device 3 can be grasped. As the height sensor 13 and the distance sensor 9, as long as the height and distance can be properly grasped, instruments with other mechanisms (for example, an ultrasonic distance measuring sensor, etc.) may be used as appropriate. .

Each of the devices that constitute the wall surface working device 1 is controlled by the control unit 10 . The control unit 10 is a control device that monitors and controls the operation of each device that constitutes the wall surface working device 1. A motor (not shown) of a hoisting machine 8 that pays out and winds up the support operation cable 4, a propeller 2c and a suction unit 5 mounted on the traveling body 2, a work device 7, a suction-related device 5a, and a work-related device 7a. A control signal is input to such devices to control their on/off and operations. Further, measurement values of the distance sensor 9 and the height sensor 13 are input to the control unit 10 as data signals.

An operation unit 11 is connected to the control unit 10. An operator of the wall surface working device 1 inputs an operation signal to the control unit 10 through operation of the operation unit 11, and the control unit 10 responds to the operation signal. Each device is controlled accordingly. In addition, a display unit 12 such as a liquid crystal display is connected to the control unit 10 as necessary, and the operation status of each device (height and lifting speed of the basket 3b, position of the traveling body 2, adsorption unit 5 and work equipment 7) is displayed. operation status, the feeding status of the support operating rope 4 from the hoisting machine 8, etc.) may be displayed. As the operation unit 11, for example, a product commercially available as a controller for a game machine or the like can be used, or a touch panel type display such as a smart phone or a tablet can be used. When the operation unit 11 is configured as a touch panel display, the operation unit 11 can also function as the display unit 12 .

Next, the operation of the first embodiment described above will be explained.

When using the wall surface working device 1, first, the support columns 3a are installed on the left and right sides of the wall surface W to be worked. A hoist 8 is loaded on each of the baskets 3b attached to the support pillars 3a, and the running body 2 is attached to a pair of support operation cables 4 drawn out from the hoist 8. As shown in FIG. While the necessary work equipment 7 is mounted on the traveling body 2, the work-related equipment 7a and the suction-related equipment 5a are loaded in the basket 3b, and the space between the suction unit 5 and the suction-related equipment 5a and between the work equipment 7 and the work-related equipment is provided. A connection cable 6 connects between the devices 7a.

In this state, the hoist (not shown) of the lifting support device 3 is operated to raise the left and right baskets 3b along the support columns 3a. The traveling body 2 is suspended by the support operating ropes 4 drawn out from the hoisting machines 8 on the left and right sides, and rises together with the basket 3b.

When the running body 2 is lifted to an appropriate height, the support operating rope 4 is paid out and wound up from the hoist 8 loaded on the left and right baskets 3b, thereby manipulating the position of the running body 2. The height and position of the running body 2 in the vertical and horizontal directions with respect to the basket 3b are determined by the amount of extension of the support operation ropes 4 from the hoisting machines 8 on the left and right sides. That is, the smaller the extension amount of the support operation cable 4, the closer the running body 2 is to the basket 3b. Further, when the hoisting machine 8 is supported by the tension of the left and right supporting operating cables 4, if the amount of the supporting operating cable 4 paid out from the left hoisting machine 8 is larger than the paid-out amount of the right hoisting machine 8 The running body 2 is positioned rightward between the left and

right support columns

3a, 3a. It is positioned leftward between the

support columns

3a, 3a.

When performing such an operation, the position of the traveling body 2 on the wall surface W can be easily grasped by, for example, the following calculation.

Let d be the distance between the winders 8 provided in the baskets 3b of the left and right lifting support devices 3 (see FIG. 4). Let l ₁ and l ₂ be the distances from the left and right winders 8 to the traveling body 2 . Assuming that the heights of the left and right winders 8 are h ₁ and h ₂ respectively, the following equation holds for the coordinates (x, y) of the traveling body 2 on the wall surface W between the left and right lifting support devices 3 .
x ² + (h ₁ −y) ² = l ₁ ² (1)
(d−x) ² +(h ₂ −y) ² =l ₂ ² (2)

The distances l ₁ and l ₂ can be grasped through the pay-out length of the support operating rope 4 from each winch 8 , and the pay-out length of the support operating rope 4 is determined by an encoder (not shown) provided in each winch 8 . can be grasped by The heights h ₁ and h ₂ can be grasped by the measured values of the height sensor 13 (see FIG. 1). Therefore, the coordinates (x, y) of the traveling body 2 can be obtained by solving the above equations (1) and (2) as simultaneous equations. In FIG. 4, the traveling body 2 and the hoisting machine 8 are indicated by dots for the sake of simplifying the calculation, but since the actual traveling body 2 and the hoisting machine 8 have sizes, they may be used in actual operation. These may be added as appropriate.

In addition, the distance d between the winders 8 is constant if each support column 3a of the lifting support device 3 is always regarded as a vertical rigid body. The tension of the support operating rope 4 bends, which may cause the distance d to fluctuate. When it is necessary to grasp the precise position of the traveling object 2 and it is necessary to take into consideration the variation of this distance d, the distance d between the cages 3b can be measured accurately by the distance sensor 9 (see FIG. 1) attached to the cages 3b. , this may be taken into account when calculating the coordinates of the traveling body 2 . Moreover, in that case, the position of the basket 3b with respect to the wall surface W or the installation surface of the support column 3a may be measured and taken into consideration. When measuring the position of the basket 3b with respect to the wall surface W or the installation surface of the support column 3a, the functions of the distance sensor 9 and the height sensor 13 may be used, or sensors (not shown) may be provided separately.

In the calculation procedure above, the position of the origin was set at the root of the support column 3a on the left side in the figure when expressing the coordinates of the traveling body 2, but the position of the origin is not limited to this and may be set as appropriate.

Here, when the running body 2 is operated, there may be some difference in height between the left and right winders 8 and the running body 2, but if the difference is too large, the running body 2 is supported from the left and right. The horizontal component of the tension of the support operation cable 4 becomes small, and there is a possibility that the operation of the lateral position of the running body 2 by the support operation cable 4 becomes difficult. In addition, since the length of the connecting cable 6 is also limited, it is not preferable that the difference in height between the left and right winders 8 and the traveling body 2 becomes too large. On the other hand, if the difference in height between the hoist 8 and the running body 2 is too small, the tension of the support operating rope 4 required to support the weight of the running body 2 increases, causing the support column 3a to bend greatly. may occur. Therefore, when operating the running body 2, care should be taken so that the height difference between the basket 3b and the running body 2 is within an appropriate range.

The traveling body 2 is held on the wall surface W by the operation of the propeller 2c and the suction unit 5, and its position in the vertical and horizontal directions with respect to the wall surface W is manipulated by the support operation rope 4 as described above. to run. Then, various operations such as inspection and painting are performed on the wall surface W by the work equipment 7 .

A series of operations such as adjustment of the height of the basket 3b, adjustment of the position of the traveling body 2 by the support operation rope 4, and various operations by the work equipment 7 can be executed by inputting an operation signal from the operation unit 11. During the work, the operating conditions of various devices are displayed on the display unit 12, and in addition to visually observing the traveling body 2 and the lifting support device 3, the detailed operating conditions can also be grasped from the visual information displayed on the display unit 12. be able to. It should be noted that the operation unit 11 may handle only some of the various operations described above. For example, the lifting and lowering of the basket 3b may be performed through another controller provided in the lifting support device 3. FIG.

During operation of the wall working device 1, if the traveling body 2 needs to be moved significantly on the wall surface, the pressing force of the propeller 2c and the adsorption force of the adsorption portion 5 can hinder the movement. In such a case, the operation of the propeller 2c and the adsorption unit 5 is turned off (or the output is reduced), and the height of the cage 3b and the extension length of the support operation rope 4 are adjusted in a state in which the pressing force and the adsorption force are cut (reduced). By doing so, the traveling body 2 can be moved more smoothly and quickly. Here, if the propeller 2c is configured as a variable pitch propeller, it is possible to reduce the pressing force while maintaining the rotation without turning off the operation of the propeller 2c. The propeller 2c and the traveling body 2 can be operated well.

Also, on the wall surface W, there may be obstacles that hinder the traveling of the traveling body 2, such as protrusions such as pillars. At that time, if the propeller 2c is a variable pitch propeller, it is possible to generate a negative pressing force to move the traveling body 2 away from the wall surface W, avoid the obstacle without detouring, and move it quickly.

When various types of work are performed on the wall surface W using the wall surface working apparatus 1, there is no need to set up scaffolding for people to come and go along the wall surface W. Since it is sufficient to install the support pillars 3a, it is possible to greatly reduce the labor and time involved in installing the scaffolding compared to the case where the work is done manually. In addition, when performing actual work such as inspection and painting on the wall surface W, there is no need for a person to move up, down, left and right using a platform or a scaffold, and the amount of work can be reduced and the construction period can be shortened. can be done. In addition, since it is not the person who directly performs the actual work on the wall surface W, but the running body 2, when supporting the running body 2 on the wall surface W, the support required is greater than when a person performs the actual work. Low strength. Therefore, it is possible to reduce the labor and time involved in the work of assembling the scaffolding as described above, and further reduce the cost required for installing the support pillars 3a themselves.

In the wall working device 1 of the first embodiment, it is difficult to work by the traveling body 2 in the vicinity of the support column 3a. Alternatively, the work may be performed by changing the installation position of the support column 3a.

In addition, the wall working device 1 of the first embodiment can also perform work that requires supporting a certain amount of weight on the wall W. For example, in the technology using a flight device as described in Patent Documents 1 and 2 above, the weight of work equipment that can be used depends on the carrying capacity of the flight device. It was only a simple work such as acquiring an image of W, and was not suitable for work using heavy equipment. In the case of the wall working device 1 of the first embodiment, most of the weight of the traveling body 2, the suction portion 5 mounted on the traveling body 2, and the working equipment 7 is due to the flight ability of the traveling body 2 and the wall surface W. Since it is supported by the tension of the support operation ropes 4 attached to the running body 2 rather than by the holding force, it is possible to support a larger weight. Furthermore, the suction-related equipment 5a used for the operation of the suction unit 5 and the work-related equipment 7a used for the work by the work equipment 7 are appropriately loaded in the basket 3b, and are connected by the connecting cable 6. , the weight necessary for the operation of the suction part 5 and the work by the work equipment 7 is shared between the traveling body 2 and the basket 3b, and the suction part 5 and the work equipment 7 are operated while the load applied to the traveling body 2 is reduced. can be made In this way, a wide range of work can be carried out with moderately heavy equipment.

FIG. 5 shows another form (second embodiment) of the wall working device in the present disclosure. The wall working device 1 of the second embodiment has the same basic configuration as that of the first embodiment shown in FIG. In addition to the supporting and operating ropes 4 , two auxiliary ropes 14 are connected to the running body 2 . Auxiliary ropes 14 are paid out from feeding devices 15 provided at the lower right and lower left positions of wall surface working device 1 (in addition to hoist 8 for feeding supporting operation ropes 4), and the tip ends of main body 2a of traveling body 2. They are connected to the lower right and lower left, respectively. In addition, although the position of the feeding device 15 for feeding the auxiliary rope 14 is near the base portions of the left and right support columns 3a in FIG.

The role of the auxiliary cable 14 in the wall working apparatus 1 of the second embodiment is to apply tension to the running body 2 from a direction different from that of the support operation cable 4, thereby suppressing the movement of the running body 2 and stabilizing its position. It is to let As in the first embodiment (see FIG. 1), when the running body 2 is supported only by the support operation ropes 4 extending from the left and right sides, the running body 2 swings back and forth against the wall surface W like a pendulum. There is a risk that this will cause trouble in the work. Therefore, as in the second embodiment, in addition to the support operation cable 4, if the auxiliary cable 14 is connected to the running body 2 and tension is applied from the auxiliary cable 14 in a direction different from that of the support operation cable 4, the running body 2 can be suppressed.

As the feeding device 15 for feeding the auxiliary rope 14, for example, a tensioning device such as the linear body feeding device described in Patent Document 3 can be used. Such a tensioning device includes a reel for feeding and winding the rope, and a motor for controlling the tension applied to the rope according to changes in the tension applied to the rope. , to constantly apply tension to said rope. Such a mechanism permits movement of a device such as a drone connected to the cable, while suppressing sudden maneuvers of the device.
