Description

[Technical field]

[0001] The present invention relates to a wall surface work system for performing work such as cleaning and painting on the wall surfaces of a structure such as a building. [Background technology]

[0002] Conventionally, when performing work such as cleaning or painting on the wall surface of a structure such as a building, the following methods have been used: The first method is to set up temporary scaffolding around the building and have workers move around on the temporary scaffolding to perform work, the second method is to use an aerial work vehicle and have workers board the aerial work vehicle to perform work, and the third method is to suspend a gondola from the roof of the building along the wall surface and have workers board the gondola to perform work (for example, see Patent Document 1).

[0003] In the first method of setting up temporary scaffolding, a large number of temporary members are required to assemble the temporary scaffolding over almost the entire surface of the building wall, and the assembly work takes a long time. In addition, when the temporary scaffolding is constructed over multiple layers, workers need to move between layers frequently when performing cleaning work, which is laborious.

[0004] In the second method using aerial work vehicles, if the vehicle has a height limit, it cannot work on walls that are higher than a certain height limit. Therefore, a method using a large-sized vehicle for aerial work is also available, but a large vehicle for aerial work needs relatively long outriggers to prevent it from falling over, and this requires a large exclusive area.

[0005] Furthermore, in the third method of suspending a gondola, it is necessary to suspend the gondola from the roof of the building and move it along the wall. This requires the installation of a large-scale dolly and rails on the roof of the building, which increases costs. Also, once the large-scale dolly and rails are installed on the roof, they are difficult to remove, which causes inconvenience when the roof is to be reused for some reason.

[0006] As both methods have problems as described above, there has been a demand for a system for working on walls that is inexpensive and easy to configure. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2012-52305 A Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention was devised in light of the above-mentioned circumstances, and its object is to provide a wall work system that can perform work on the walls of buildings with a simple configuration and at low cost. [Means for solving the problem]

[0013] In the wall work system of the present invention, the control means is provided with a communication unit for communicating with the rooftop side cart and the ground side cart, the rooftop side cart is provided with a rooftop side communication unit for communicating with the communication unit, and the ground side cart is provided with a ground side communication unit for communicating with the communication unit, and the communication units are capable of communicating wirelessly with the rooftop side communication unit and the ground side communication unit, respectively. Effect of the Invention

[0014] According to the present invention, the wall surface work structure suspended by a wire stretched between the rooftop side cart and the ground side cart is moved left and right along the wall surface of the building by the rooftop side cart running along the rooftop side rail and the ground side cart running along the ground side rail.

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0018] 1 shows the configuration of a wall surface work system according to the present invention, where (a) is a front view and (b) is a side view. This wall surface work system is for performing work such as cleaning, repairing, painting, and imaging on the wall surface of a structure (such as a building) B.

[0019] The wall work system is roughly composed of a rooftop rail 1 laid on the floor surface of the roof of building B, a rooftop cart 2 running along the rooftop rail 1, a wall work body 3 that performs work on the wall of building B, a ground side rail 4 laid on the ground, a ground side cart 5 running along the ground side rail 4, a wire W stretched between the rooftop side cart 2 and the ground side cart 5, and a control device (described later) not shown.

[0020] The wall surface work system supports a wall surface work body 3 with a wire W stretched across a rooftop side cart 2 and a ground side cart 5, which move on rooftop side rails 1 and ground side rails 4, respectively, to move the wall surface work body 3 in the left-right direction along the wall surface of a building B. In addition, the wire W is wound up and unwound by a winch 35 (described later) mounted on the ground side cart 5, to move the wall surface work body 3 in the up-down direction along the wall surface.

[0021] A control device (not shown) is for controlling the operation of the rooftop cart 2 and the ground cart 5. The wall work vehicle 3 performs work such as cleaning, repairing, painting, and photographing the wall surface of the building B, but the work is not limited to these.

[0022] The rooftop-side cart 2 is used to suspend and support the wall work body 3 from a height position on the roof of building B, and to move the wall work body 3 along the wall surface of building B. As shown in Figures 2 and 3, the rooftop-side cart 2 is formed into a roughly rectangular frame shape by combining multiple types of temporary construction members. More specifically, the main body of the rooftop-side cart 2 is made up of multiple support members 6 that extend mainly in the vertical direction, and multiple horizontal members 7 that connect the support members 6 horizontally.

[0023] Two-stage horizontal platforms (not shown) are provided on the horizontal surface formed by the multiple horizontal members 7, and the upper stage horizontal platform is provided with a rooftop-side control unit 8 that mainly drives and controls the travel of the rooftop-side cart 2. The lower stage horizontal platform is provided with a motor battery 9 that supplies power to a travel motor 26, which will be described later.

[0024] On either side of the rooftop cart 2, there are provided two protruding beam members 10 each consisting of two single pipes extending in parallel toward the wall of building B. Each protruding beam member 10 is connected to two support members 6 and extends horizontally from the roof to the wall. The tip of each protruding beam member 10 extends into the space beyond the wall of building B, and a pulley 12 is provided near the tip via a connecting member 11 extending diagonally downward. A wire W connected to the ground cart 5 and the wall work body 3 is hung between these pulleys 12.

[0025] Of the four support members 6 of the rooftop cart 2, the two support members 6 on the wall side are each provided at their lower ends with wheels 14 that are rotatable via support members 13 that are U-shaped in cross section. In addition, a drive mechanism 15 (see FIG. 3) for running the rooftop cart 2 is provided at the lower ends of the two support members 6 on the rear side (the drive mechanism 15 will be described later).

[0026] 4 is a side view of the rooftop rail 1 when the rooftop cart 2 is not on the rooftop rail 1. The rooftop rail 1 is composed of a pair of rails laid parallel to the wall direction on the roof of building B, and consists of a front rail 17 closer to the wall and a rear rail 18 farther from the wall.

[0027] The front rail 17 is formed by connecting multiple round steel members that are approximately cylindrical and extend in the running direction. The front rail 17 is supported by multiple support pieces 19 that extend perpendicular to the extension direction and have a generally L-shaped cross section. When the rooftop cart 2 runs, its wheels 14 roll on the front rail 17 (see Figures 2 and 3).

[0028] On the other hand, as shown in Figures 4 and 5, the rear rail 18 is formed in a shape in which the back faces of so-called C-shaped steel are joined together, and is composed of a main body 20 extending in the running direction of the rooftop cart 2, and a protrusion 21 provided on the upper part of the main body 20 and extending in the same running direction. The main body 20 is formed by connecting a plurality of the above-mentioned C-shaped steel. The rear rail 18 is supported by a plurality of support pieces 19, similar to the front rail 17. The protrusion 21 has a wavy rack 22 formed on its upper surface. A pinion 25 (described later) provided in the drive mechanism 15 of the rooftop cart 2 is engaged with this rack 22.

[0029] Fig. 6 shows the internal structure of the drive mechanism 15 of the rooftop-side cart 2, and shows the state when the rooftop-side cart 2 runs on the rooftop-side rail 1. Fig. 7 is a view seen from the rear of Fig. 6. The drive mechanism 15 of the rooftop-side cart 2 is roughly composed of a covering member 23 provided extending in the running direction so as to support the two rear support members 6, a pair of wheels 24 provided on the inside near both ends of the covering member 23, a pinion 25 meshed with the protrusion 21 of the rear rail 18, and a travel motor 26 for applying a rotational force to the pinion 25.

[0030] The covering member 23 is open at the bottom and is formed in a roughly U-shape in cross section, and as shown in Fig. 7, the lower ends of the two rear support members 6 are connected to the upper surface near both ends. The pair of wheels 24 are provided on the inside of the covering member 23 so as to be located below the two rear support members 6 in rear view (see Fig. 7). As shown in Fig. 6, each of the pair of wheels 24 consists of two wheels arranged with their outer surfaces facing each other, and the two wheels are provided to be rotatable around pivot shaft 24a and roll inside the main body 20 of the rear rail 18 when the rooftop cart 2 is traveling.

[0031] The pinion 25 is provided rotatably about a rotation shaft 27 inside the covering member 23 so as to be located near the center of the covering member 23 when viewed from behind (see FIG. 7). The rotation shaft 27 is supported by a pair of bearings 28.

[0032] The travel motor 26 is attached to the inner side surface of the covering member 23, and its axis is connected to the rotating shaft 27. The travel motor 26 rotates when power is supplied from the motor battery 9 described above, and the rotating shaft 27 and pinion 25 also rotate accordingly, and the pinion 25 moves on the rack 22 of the protrusion 21. The rotational force of the travel motor 26 causes the wheels 14 of the rooftop cart 2 to roll on the front rail 17, and the pair of wheels 24 to roll inside the main body 20 of the rear rail 18, causing the rooftop cart 2 to travel along the rear rail 18.

[0033] In this way, the protrusion 21 of the rear rail 18 and the pinion of the drive mechanism 15 are in contact with each other in a so-called rack and pinion relationship, so that the rooftop cart 2 is positioned on the rooftop rail 1 with high precision.

[0034] Fig. 8 is a front view showing the configuration of the ground-side cart 5, and Fig. 9 is a side view of the same. The ground-side cart 5 is used to move the wall surface work body 3, which is suspended and supported by the rooftop-side cart 2, in the left-right direction along the wall surface of the building B. The ground-side cart 5 is also used to move the wall surface work body 3 in the up-down direction using a winch 35 (described later).

[0035] The ground-side rail 4 is configured in a manner similar to the roof-side rail 1 described above, and consists of a pair of rails laid parallel to the wall direction near the wall of building B, with a front-side rail 30 made of round steel on the side away from the wall, and a rear-side rail 31 made of C-shaped steel on the side closer to the wall.

[0036] The ground side cart 5, like the rooftop side cart 2, is formed into a substantially rectangular parallelepiped frame shape by combining a plurality of support members 32 and a plurality of horizontal members 33. The ground side cart 5 is provided with a two-stage horizontal platform (not shown), and the upper horizontal platform is provided with a ground side control unit 34 that mainly drives and controls the travel of the ground side cart 5 and controls the movement of the wall surface work body 3. The lower horizontal platform is provided with a winch 35 for moving the wall surface work body 3 in the vertical direction, a winch battery 36 for supplying power to the winch 35, and a motor battery 38 for supplying power to a travel motor 37 for traveling the ground side cart 5.

[0037] Fig. 10 is a schematic perspective view seen from above the wall surface, showing the winding configuration of the wire W around the drum 39 of the winch 35. Here, as shown in Fig. 10, the winch 35 is a so-called dual-pulling type, and is capable of winding and unwinding two wires W around the substantially cylindrical drum 39. When the wire W1 on one side is in a winding state, the wire W2 on the other side is in a unwinding state.

[0038] More specifically, the wire W1 on one side is hung over a first pulley 41 (see Figs. 8 and 9) that converts its movement between the vertical direction and the horizontal direction, and is hung over a second pulley 42 (see Fig. 9) that converts its horizontal movement to an orthogonal direction, and is wound around the drum 39 of the winch 35. The wire W2 on the other side is hung over a third pulley 43 (see Fig. 8) that converts its movement between the vertical direction and the horizontal direction, and is hung over a fourth pulley 44 that converts its horizontal movement to an orthogonal direction, and is wound around the drum 39 of the winch 35.

[0039] The winch 35 is driven by power supplied from a winch battery 36, and can rotate forward and reverse in response to a control signal from the ground-side control unit 34. For example, when the winch 35 is rotated forward (see arrow A in FIG. 10), the wire W1 on one side is wound up, which moves the wall work body 3 downward along the wall surface. When the winch 35 is rotated reversely (see arrow B in FIG. 10), the wire W1 on one side is unwound, which moves the wall work body 3 upward along the wall surface.

[0040] The ground-side cart 5, similar to the rooftop-side cart 2, is provided with rotatable wheels 46 via support members 45 at the lower ends of the two support members 32 on the opposite side to the wall side, and a drive mechanism 47 for running the ground-side cart 5 is provided at the lower ends of the two support members 32 on the wall side. The configuration of the drive mechanism 47 is similar to that of the drive mechanism 15 of the rooftop-side cart 2.

[0041] The running motor 37 is rotated by a motor battery 38, and the rotational force of this running motor 37 causes the wheels 46 to roll on the front rail 17 of the ground rail 4, while a pair of wheels 24 of the drive mechanism 47 roll on the inside of the main body 20 of the rear rail 18, causing the ground cart 5 to run along the ground rail 4.

[0042] 11 is a diagram showing the electrical configuration of the wall surface work system. In this wall surface work system, the operation of the rooftop side cart 2 and the ground side cart 5 is controlled by a control device 50. The control device 50 is composed of a personal computer or the like installed in an operation room or the like provided on the ground, and has a control unit 51 that generally manages the operation of the rooftop side cart 2 and the ground side cart 5.

[0043] Connected to the control unit 51 are a communication unit 52 for wirelessly communicating data with a communication unit 55 (described later) of the rooftop cart 2, a communication unit 53 for wirelessly communicating data in the same manner as with the ground cart 5, and an operation unit 54 equipped with switches for moving the wall work body 3. Although not shown, the operation unit 54 is equipped with a right direction switch for moving the wall work body 3 to the right along the wall surface, a left direction switch for moving it to the left, an up direction switch for moving it upwards, a down direction switch for moving it downwards, etc.

[0044] The rooftop side cart 2 is equipped with a rooftop side control unit 8, which is connected to a communication unit 55 for wirelessly communicating data with the communication unit 52 of the control device 50, and a motor battery 9 for supplying power to the driving motor 26.

[0045] In addition, the ground side trolley 5 is equipped with a ground side control unit 34, and the ground side control unit 34 is connected to a communication unit 56 for wireless data communication with the communication unit 53 of the control device 50, a motor battery 38 for supplying power to the traveling motor 37, and a winch battery 36 for supplying power to the winch 35.

[0046] Next, the operation of the above configuration will be described.

[0047] In this wall surface work system, the operation of the rooftop side cart 2 and the ground side cart 5 is controlled by the control unit 51 of the control device 50, and the wall surface work body 3 is moved in the left-right and up-down directions along the wall surface.

[0048] That is, when the worker moves the wall surface working body 3 to the right, he operates the right direction switch provided on the operation unit 54 of the control device 50. This causes the control unit 51 to transmit right direction control signals to the rooftop side cart 2 and the ground side cart 5 via the communication units 52 and 53, respectively, based on the right direction control signal from the operation unit 54.

[0049] When the rooftop-side control unit 8 of the rooftop-side cart 2 receives the rightward control signal via the communication unit 55, it sends a drive signal to the motor battery 9 and a control signal indicating the rotation direction of the traveling motor 9 corresponding to the rightward movement of the wall work body 3. This causes the traveling motor 26 to be rotationally driven in the rotation direction indicated by the control signal, and the rooftop-side cart 2 travels to the right on the rooftop-side rail 1 as shown in Fig. 12 (see arrow C in Fig. 12).

[0050] Furthermore, when the ground-side control unit 34 of the ground-side cart 5 receives the control signal for the rightward direction via the communication unit 56, it sends a drive signal to the motor battery 38 and a control signal indicating the rotation direction of the traveling motor 37 corresponding to the rightward movement of the wall surface working body 3. As a result, the traveling motor 37 is rotationally driven in the rotation direction indicated by the control signal, and the ground-side cart 5 travels to the right on the ground-side rails 4 (see arrow D in FIG. 12).

[0051] As described above, when the rooftop cart 2 runs to the right on the rooftop rail 1 and the ground cart 5 runs to the right on the ground rail 4, the wall work body 3 suspended from them by the wire W also moves to the right along the wall surface (see arrow E in Figure 12).

[0052] In this case, a control signal from the control device 50 is sent synchronously to the rooftop cart 2 and the ground cart 5, so that the rooftop cart 2 and the ground cart 5 also move synchronously in response to this, thereby ensuring that the wall work body 3 is moved reliably to the right while maintaining a horizontal state.

[0053] In this way, the rooftop cart 2 and the ground cart 5 move synchronously, which makes it possible to prevent undue tension from being applied to the wire W supporting the wall surface working body 3. In addition, since the vertical orientation of the wire W can be maintained, the positioning accuracy of the wall surface working body 3 relative to the wall surface can be improved.

[0054] On the other hand, when the worker moves the wall surface working body 3 to the left, he operates the left direction switch provided on the operation unit 54 of the control device 50. The procedure thereafter is the same as the procedure after the right direction switch is operated as described above, and this ensures that the wall surface working body 3 is moved reliably to the left while maintaining a horizontal state.

[0055] Next, when the worker moves the wall surface working body 3 upward, he operates the upward switch provided on the operation unit 54 of the control device 50. This causes the control unit 51 to transmit an upward control signal only to the ground side cart 5 via the communication unit 53 based on the upward control signal from the operation unit 54.

[0056] When the ground-side control unit 34 of the ground-side cart 5 receives the upward control signal via the communication unit 56, it sends a drive signal to the winch battery 36 and a control signal indicating the rotation direction of the drum 39 of the winch 35 corresponding to the upward movement of the wall surface working structure 3. This causes the drum 39 of the winch 35 to be rotationally driven in the rotation direction indicated by the control signal, and the wire W is paid out. As a result, the wall surface working structure 3 suspended by the wire W moves upward along the wall surface (see arrow F in FIG. 13).

[0057] On the other hand, when the worker moves the wall surface working structure 3 downward, he operates the downward switch provided on the operation unit 54 of the control device 50. The procedure thereafter is the same as that when the above-mentioned upward switch is operated, and the drum 39 of the winch 35 is rotated in the rotation direction indicated by the control signal, and the wire W is wound up. Therefore, the wall surface working structure 3 suspended by the wire W moves downward along the wall surface.

[0058] In this way, the rotation of the winch 35 of the ground-side cart 5 is controlled, so that the wall surface working body 3 is moved upward or downward along the wall surface. At this time, the rooftop-side cart 2 and the ground-side cart 5 each remain stopped, so that the wall surface working body 3 is reliably moved in the vertical direction.

[0059] As described above, the wall surface working body 3 can be moved independently to the right or left and upward or downward, but as shown in Fig. 14, the wall surface working body 3 may be moved by combining left-right and upward / downward movements. That is, the control device 50 may supply power synchronously to the travel motor 26 of the rooftop side cart 2, the travel motor 37 of the ground side cart 5, and the winch 35. This allows the wall surface working body 3 to move on the wall surface in a generally mountain-like shape or along an arbitrary trajectory (for example, a curved or circular shape). These movements are possible, for example, by using software programmed in the control unit 51 of the control device 50.

[0060] The scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, the shape, size, and quantity of each component of the wall surface work system in the above embodiment are not limited to the above embodiment, and can be appropriately modified in design.

[0061] In addition, in the above embodiment, the winch 35 for moving the wall surface working body 3 in the vertical direction is provided on the ground side cart 5, but instead, the winch 35 may be provided on the rooftop side cart 2.

[0062] In addition, in the above embodiment, the wall surface working body 3 is suspended and supported by two wires W, but as shown in Fig. 15, the wall surface working body 3 may be suspended by a single wire W. In this case, the rooftop side cart 2 and the ground side cart 5 may each be provided with a winch for winding up and paying out the wire W. [Explanation of symbols]
