Description

[Technical field]

[0001] The present invention relates to rooftop equipment provided on the roof of a structure such as a building, and more particularly to rooftop equipment for wall surface work for moving a wall surface work device that performs work on a wall surface. [Background technology]

[0002] Conventionally, when performing work such as cleaning or painting on the walls of a structure such as a building, a method has been adopted in which a gondola is suspended along the wall from the roof of the building and workers board the gondola to perform the work (see, for example, Patent Document 1).

[0003] In this method of using a gondola, the gondola is suspended from the roof of a building and moved along the wall. In this case, rooftop equipment is usually provided on the roof to suspend and move the gondola, and the equipment consists of a rail and a cart that runs on the rail and supports the gondola.

[0004] However, when moving a gondola while suspending it, in order to ensure stable movement of the gondola and to prevent the gondola from falling, it is necessary to provide a relatively large cart and sturdy rails to support and move the cart, which increases the cost of the equipment.

[0005] In addition, once a large-scale cart and rails are installed on the roof, they are difficult to remove, which creates inconvenience when the roof is to be reused for some reason. Furthermore, in order to run a large-scale cart, a relatively large power supply facility that supplies a suitable power supply voltage (e.g., three-phase 200V) is also required, which is a factor in increasing the equipment costs.

[0006] One option is to assemble the cart for the rooftop equipment out of lightweight materials, such as temporary components. However, if the cart is too light, it may not be able to withstand the weight of the gondola and may float up and tip over, meaning that the cart may not be able to support the gondola properly and stably.

[0007] [Patent Document 1] JP 2000-352189 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 rooftop equipment for wall surface work that is low-cost, easy to construct, and capable of providing good support for wall surface work equipment. [Means for solving the problem]

[0009] The rooftop equipment for wall work provided by the present invention is a rooftop equipment for wall work for moving a wall work device for working on a wall of a building along the wall, and comprises a rail made of a plurality of steel members that can be freely connected and laid on the roof of the building, and a cart made of a plurality of temporary members, which supports the wall work device by suspending it via a wire and runs on the rail, the rail consisting of a first rail member provided on the wall side and a second rail member provided on the opposite side to the wall side, the second rail member having a main body portion formed in a shape where the back faces of a pair of C-shaped steel are joined together, and the cart has at least a pair of wheels that roll inside the main body portion.

[0010] In the rooftop equipment for wall work of the present invention, the cart is provided with a drive mechanism for running on the rails, and the drive mechanism is driven by the rotational force of an electric tool.When the drive mechanism is driven, the cart runs on the rails, thereby moving the wall work device in the left-right direction along the wall surface of the building.

[0011] In the rooftop equipment for wall work of the present invention, the cart is equipped with a winch for winding and paying out the wire, and the winch is driven to wind or pay out the wire, thereby moving the wall work device in the vertical direction along the wall surface of the building. Effect of the Invention

[0012] According to the present invention, the second rail member of the rails laid on the roof of the building has a body formed in a shape of the back faces of C-shaped steel joined together, and when the cart runs, a pair of wheels roll inside the body. Therefore, even if the rail is made of multiple steel materials that can be freely connected and the cart running on the rail is made of multiple temporary materials, the cart can be prevented from floating up or falling over, and the cart can run stably and well on the rail. Therefore, it is possible to provide a rooftop facility for wall surface work that is low-cost and easy to configure and can well support a wall surface work device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0015] 1 is a diagram showing the configuration of a wall surface work system to which the rooftop equipment for wall surface work according to the present invention (hereinafter simply referred to as "rooftop equipment") is applied, (a) being a front view and (b) being a side view. The wall surface work system is for carrying out work such as cleaning, repairing, painting, or imaging on the wall surface of a structure (such as a building) B, for example.

[0016] The wall surface work system is composed of rooftop equipment 1 provided on the rooftop of building B, a wire W suspended from the rooftop equipment 1 along the wall surface of building B, and a wall surface work device E connected to the wire W and performing work on the wall surface of building B. The wall surface work device E performs work such as cleaning, repairing, painting, and photographing on the wall surface of building B, but the work is not limited to these.

[0017] The rooftop equipment 1 consists of rails 2 laid on the floor surface of the roof of building B, and a cart 3 that runs along the rails 2. The cart 3 moves on the rails 2 to move a wall surface work device E supported by a wire W in the left-right direction along the wall surface of building B. In addition, the cart 3 moves the wall surface work device E in the up-down direction along the wall surface by winding up and paying out the wire W with a winch 6 (described later) mounted on the cart 3.

[0018] 2 and 3, the cart 3 is formed into a substantially rectangular parallelepiped frame by combining a plurality of types of temporary construction members. More specifically, the body of the cart 3 is made up of a plurality of support members 4 extending mainly in the vertical direction, and a plurality of horizontal members 5 connecting the support members 4 horizontally. A two-stage horizontal platform (not shown) is provided on the horizontal surface formed by the horizontal members 5, and the lower horizontal platform is provided with a winch 6 for moving the wall surface work device E in the vertical direction, and a winch battery 7 (see FIG. 3) for supplying power to the winch 6.

[0019] The winch 6 is for moving the wall surface work device E up and down along the wall surface by winding and unwinding the wire W. The winch 6 can rotate a built-in drum (not shown) forward and backward in response to a control signal from, for example, a remote control (not shown) connected to the winch 6 by wire or wirelessly. The remote control is provided with an up switch, a down switch, a stop switch, etc.

[0020] The winch 6 is driven by power supplied from a winch battery 7 and is capable of rotating forward or reverse. For example, when the up switch on the remote control is operated, the winch 6 rotates forward and the wire W is wound up. When the down switch on the remote control is operated, the winch 6 rotates reversely and the wire W is unwound.

[0021] A protruding beam member 8 made of a single pipe extending horizontally toward the wall surface of building B is provided on the side of the cart 3. The protruding beam member 8 is connected to two of the four support members 4 of the cart 3. The tip of the protruding beam member 8 extends into a space beyond the wall surface of building B, and a pulley 10 is provided near the tip via a connecting member 9 extending downward. The wire W reeled out from the winch 6 is hung on a pulley 12 provided on the horizontal member 5 of the cart 3 via a connecting member 11, and is also hung on the pulley 10 and connected to the wall surface work device E.

[0022] Of the four support members 4 of the dolly 3, the two support members 4 on the wall side are each provided at their lower ends with wheels 15 that are rotatable via support members 14 that are U-shaped in cross section. In addition, a drive mechanism 16 (see FIG. 3) for running the dolly 3 is provided at the lower ends of the two support members 4 on the rear side (the drive mechanism 16 will be described later).

[0023] Fig. 4 is a side view of the rail 2, and Fig. 5 is a rear view of the rail 2, both of which are views of the case where the trolley 3 is not on the rail 2. The rail 2 is composed of a pair of rails laid parallel to the wall direction on the roof of the building B, and is made up of a front rail 17 closer to the wall and a rear rail 18 farther from the wall.

[0024] The front rail 17 is formed by connecting multiple round steel members that are approximately cylindrical and extend in the traveling direction. The front rail 17 is supported by multiple support pieces 19 that extend perpendicular to the extension direction and have a approximately L-shaped cross section. When the bogie 3 travels, its wheels 15 roll on the front rail 17 (see Figures 2 and 3). The support pieces 19 may be attached to the floor surface of the roof by bolts or the like, or may be supported in a fixed position by weights or the like.

[0025] On the other hand, the rear rail 18 is composed of a main body 20 extending in the running direction of the bogie 3, 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 in a shape in which the back faces of a pair of so-called C-shaped steel are joined together, and is formed by connecting a plurality of pairs of these C-shaped steel in the running direction. 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 (see the circle in FIG. 5). A pinion 25 (described later) provided in the drive mechanism 16 is engaged with this rack 22.

[0026] As described above, the dolly 3 is set up by combining multiple types of temporary members, so the material costs are relatively low, and since it can be easily assembled into the desired shape by workers, the assembly work costs are not bulky. Also, since the rails 2 are made of round steel materials and C-shaped steel as described above, the material costs and work costs can be reduced, similar to the dolly 3. Therefore, the rooftop equipment consisting of the rails 2 and the dolly 3 can be easily installed on the rooftop of the building B and easily removed.

[0027] Therefore, unlike the method of suspending the gondola explained in the "Background Art" section, there is no need to install a large-scale rooftop facility consisting of a cart and rails to support the gondola on the roof of the building. This makes it possible to significantly reduce the equipment costs associated with installing a large-scale rooftop facility.

[0028] Fig. 6 shows the internal structure of the drive mechanism 16 of the carriage 3, and shows the state when the carriage 3 runs on the rail 2. Fig. 7 is a view seen from the rear direction of Fig. 6 (note that an electric driver D (described later) is omitted in Fig. 7). The drive mechanism 16 is roughly composed of a covering member 23 extending in the running direction, a pair of wheels 24 provided inwardly near both ends of the covering member 23, and a pinion 25 that meshes with a protrusion 21 of the rear rail 18.

[0029] The covering member 23 is formed in a generally U-shape with an open bottom in cross section, and as shown in Fig. 7, the lower ends of the two rear support members 4 are connected and supported on the upper surface near both ends. The pair of wheels 24 are arranged inside the covering member 23 so as to be located below the two rear support members 4 in rear view (see Fig. 7). More specifically, each of the pair of wheels 24 is made up of two wheels 24 arranged with their outer surfaces facing each other as shown in Fig. 6, and the two wheels 24 are each supported so as to be rotatable about a rotation shaft 26, and roll inside the main body 20 of the rear rail 18 when the bogie 3 is traveling.

[0030] The pinion 25 is supported rotatably about a rotating 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 rotating shaft 27 is supported by being suspended from the covering member 23 by a pair of bearings 28, and is connected to a driver receiver 30 provided on the side of the covering member 23.

[0031] 6, for example, a rechargeable electric screwdriver D is attached to the screwdriver receiver 30. That is, the operator attaches the electric screwdriver D to the screwdriver receiver 30 and operates it to rotate the electric screwdriver D.

[0032] When the electric screwdriver D is driven to rotate, the rotary shaft 27 and the pinion 25 rotate accordingly, and the pinion 25 moves on the ridge 21 meshed therewith. That is, the configuration of the pinion 25 and the ridge 21 converts the rotational motion of the pinion 25 into the linear motion of the ridge 21. Therefore, a moving force is applied to the covering member 23 in the traveling direction. As a result, the pair of wheels 24 roll on the inside of the main body 20 of the rear rail 18, and the wheels 15 of the cart 3 roll on the front rail 17. Thus, the cart 3 runs on the rail 2.

[0033] As described above, in this embodiment, the main body 20 of the rear rail 18 is formed in a shape in which the back faces of C-shaped steel are joined together, and when the cart 3 runs, a pair of wheels 24 roll inside the main body 20. Therefore, even if the rail 2 and the cart 3 are made of temporary materials and the cart 3 suspends the wall surface work device E by the wire W supported by the protruding beam member 8, the cart 3 can be prevented from floating up or tipping over. Therefore, the cart 3 can run on the rail 2 stably and well.

[0034] In addition, in this embodiment, the cart 3 runs on the rails 2 by rotating the electric screwdriver D, and as described above, if a rechargeable electric screwdriver D is used, there is no need to provide any new power supply equipment for running the cart 3.

[0035] Furthermore, in this embodiment, the protrusion 21 of the rear rail 18 and the pinion of the drive mechanism 16 are engaged in a so-called rack and pinion relationship, so that the carriage 3 can be positioned on the rail 2 with high precision in the traveling direction.

[0036] Next, the operation of the above configuration will be described.

[0037] In the rooftop equipment 1 of the present invention, when a worker wants to run the cart 3 on the rail 2, he attaches the electric screwdriver D to the screwdriver receiver 30 of the covering member 23 and drives it in a predetermined rotational direction. When the electric screwdriver D is driven to rotate, the rotational driving force is applied to the pinion 25, and the rotational motion is converted into linear motion by the pinion 25 and the protrusion 21 meshed therewith. This causes the covering member 23 to move along the rear rail 18.

[0038] This movement of the covering member 23 causes the pair of wheels 24 to roll on the inside of the main body 20 of the rear rail 18, and also causes the wheels 15 of the cart 3 to roll on the front rail 17. This causes the cart 3 to run on the rail 2 (see arrow A) as shown in Figure 8. When the cart 3 runs on the rail 2, the wall surface work device E suspended from the cart 3 by a wire W also moves along the wall surface in the same direction as the cart 3 (see arrow B in the figure).

[0039] Furthermore, when the worker rotates the electric screwdriver D in the opposite direction to the above, the rotational drive force of the electric screwdriver D in the opposite direction is applied to the pinion 25. Then, the rotational motion is converted into linear motion by the relationship between the pinion 25 and the protrusion 21, and the covering member 23 moves along the rear rail 18 in the opposite direction to the above. As a result, the cart 3 travels along the rail 2 in the opposite direction to the direction shown in Fig. 8. Accordingly, the wall surface work device E suspended from the cart 3 also moves along the wall surface in the opposite direction.

[0040] In this way, the wall surface work device E is moved leftward or rightward along the wall surface by rotating the electric screwdriver D. At this time, the winch 6 of the dolly 3 remains stopped, so the wall surface work device E is reliably moved horizontally while maintaining its height direction.

[0041] Next, when the worker wishes to move the wall surface work device E upward, he operates the upward switch provided on the remote control of the winch 6. This causes the remote control to send a drive signal and a control signal indicating the forward rotation direction of the winch 6 to the winch battery 7. This causes the winch 6 to be driven to rotate in the forward rotation direction, and the wire W is wound up. Therefore, the wall surface work device E suspended by the wire W moves upward along the wall surface (see arrow C in FIG. 9).

[0042] On the other hand, when the worker wishes to move the wall surface work device E downward, he operates the downward switch provided on the remote control of the winch 6. The procedure thereafter is the same as that when the above-mentioned upward switch is operated, and the winch 6 is driven to rotate in the reverse direction indicated by the control signal, and the wire W is paid out. Therefore, the wall surface work device E suspended by the wire W moves downward along the wall surface.

[0043] In this way, the wall surface work device E is moved upward or downward along the wall surface by controlling the rotation of the winch 6. At this time, since the dolly 3 remains stopped, the wall surface work device E is reliably moved in the height direction.

[0044] In the above operation, the worker may operate the electric screwdriver D while operating the remote control of the winch 6, thereby moving the wall surface work device E in either the left or right direction while simultaneously moving it in either the up or down direction.

[0045] The scope of the present invention is not limited to the above-mentioned 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 rooftop equipment for wall work in the above-mentioned embodiment are not limited to the above-mentioned embodiment, and can be appropriately modified in design.

[0046] In addition, in the above embodiment, the support piece 19 supporting the front rail 17 and the rear rail 18 is attached to a flat roof surface. However, for example, if the roof floor surface is a folded roof, the support piece 19 may be attached to the roof floor surface using a so-called seam mounting bracket. [Explanation of symbols]
