2. Description of the Related Art In recent years, buildings, apartments, schools, hospitals,
There is a tendency to increase the number of buildings having a steel structure used for various purposes such as parking lots and warehouses. In a construction site of such a building, a work of spraying a fire-resistant coating material on steel frames constituting the building is performed.

[0003] In such a case, in the conventional spraying operation of the refractory coating material, an operator holds the tip of a nozzle from which the refractory coating material is sprayed, and sprays it on a work scaffold installed around a building or the like. I was working. Then, another worker other than the worker performing the spraying operation has moved the scaffold and routed a hose for supplying the fireproof covering material.

[0004]

The above-mentioned conventional spraying operation of the refractory coating material is a work at a high place on a scaffold. However, this scaffold is a small and movable one having a narrow work floor. Was common.

[0005] In addition, a worker who sprays must wear protective clothing or a mask to protect himself from the rebound of the sprayed coating material and the generation of dust. For this reason, such work becomes heavy labor. Therefore, there is a problem that the work time that can be performed in one day is necessarily limited, so that labor saving of the spraying work has been strongly desired.

[0006] On the other hand, the spraying operation of the refractory coating material to the mold steel or the non-uniform portion has a large spray area depending on the site, and therefore, there is a limit in automation by a robot or the like. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a spraying device for building refractory coating material capable of performing a spraying operation quantitatively and automatically.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. A bogie 1 having wheels 5 supported by bearings at both ends and having a concave center is provided at the lower part of the device. The carriage 1 is free to travel when the wheels 5 are driven by the drive motor 3. The cart 1 can be fixed at a fixed position by a brake device (not shown).

The running direction of the wheels 5 is changed by the rotation of the bearings by the operation of the steering motors 7, 7 mounted on both ends of the bogie 1. On the carriage 1, an elevating device 9 that expands and contracts in the vertical direction is provided adjacent to the steering motors 7,7. With this elevating device 9, a boom as a support 11 extending in the same direction as the traveling direction of the carriage 1 is provided so as to be able to elevate and lower. As the elevating device 9, for example, a ball screw device or a hydraulic cylinder that supports the support body 11 at the upper two places and is rotated by the elevating motor 13 can be used.

A first rail 15 is provided on the support 11 along the longitudinal direction. This first rail 15
The first roller 17 is movably provided inside the U-shaped cross section of the arrow.

On the other hand, a second rail 19 is provided on the first rail 15 so as to intersect with the first rail 15. The second rail 19 is provided with a base 21 projecting from the bottom thereof.
It is supported by rollers 17. This second rail 19
Also has a U-shaped cross section, and the second roller 23 is movably housed inside. The nozzle device 25 is mounted on the second rail 19. This nozzle device 25 has a second
It is supported on the base portion 27 by the roller 23.

The first roller 17 is driven by a first moving motor 28, and the second roller 23 is driven by a second moving motor 30, respectively. Therefore, the second rail 19 travels on the first rail 15 and can move in a direction parallel to the traveling direction of the bogie 1, and the nozzle device 25 travels on the second rail 19 and is orthogonal to the above. It can move in any direction.

The support 11 having the first rail 15
Is rotatable around one of the lifting / lowering devices 9 within a predetermined angle θ (FIG. 3). The nozzle device 25 has a vertically extending arm 29, and a nozzle 33 is attached to the upper end of the arm 29 via a frame 31. This arm 29 is extendable in the vertical direction (Y direction). Further, the frame 31 rotates around the Y axis,
Rotation around an axis (an axis perpendicular to the paper surface) is possible.

The nozzle 33 is capable of horizontal swing (rotation about the Y axis) and vertical swing (rotation about the Z axis) with respect to the frame 31. It also has a spraying mechanism (not shown) so that the refractory coating material supplied by a supply hose (not shown) can be blown by a predetermined gas pressure.

The nozzle device 25 has a total of five degrees of freedom due to the operation of the frame 31 and the nozzles 33 and the travel on the second rail 19. The control device according to the present embodiment includes a control device provided in a control panel 35 installed in a concave portion of the bogie 1, and a control device that is operated by an operator to issue a command to the control device by wire or wirelessly. Consists of

The control device includes a driving motor 3 for the carriage 1, a steering motor 7, a lifting motor 13 for the lifting device 9,
The motors 28 and 30 for moving the rails 15 and 19 and the nozzle device 25 are controlled.

The control device has a lever that moves in the same manner as the frame 31 and the nozzle 33 of the nozzle device 25. When the operator operates this lever, the nozzle device 25 performs the same movement as the operation. You can steer to do it.

The control device can be programmed in advance with a spraying operation consisting of a simple repetitive operation, and can automatically spray. Hereinafter, the operation of the present embodiment will be described.

First, an operator operates the drive motor 3 to move the carriage 1 to a predetermined place and fix it by a control device (not shown). Thereafter, the support 11 is moved up and down by the operation of the elevating device 9, and the two moving motors 2 are moved.
The second rail 19 and the nozzle device 25 are moved by the operations of 8, 30. Thereby, the nozzle device 25 reaches a predetermined position. Then, the lever provided on the steering device is moved so as to actually operate the nozzle itself.

In this manner, as described above, the direction and attitude of the nozzle can be changed by the nozzle device 25 that is variable in the range of five degrees of freedom. The spray of the refractory coating material is performed from the nozzle 33 while appropriately performing such a change.

As described above, the traveling and lifting device 9 of the carriage 1
The nozzle device 25 can reach a predetermined position by the lifting and lowering of the support 11, the movement of the second rail 15 by the first movement motor 28, and the movement of the nozzle device 25 by the second movement motor 30. It is.

In addition, since the nozzle 33 can be sprayed while freely moving with the above-mentioned five degrees of freedom in accordance with the movement of the lever of the control device, even a portion of a steel structure having a complicated shape can be easily coated with the fireproof coating material. Spraying can be performed.

If the spraying is not for a complicated part but is a simple repetitive operation, a command for automatic control is input to the steering device. By operating a program pre-installed in the control device, the nozzle device 25 can be moved in a horizontal plane along the rail 19, and spraying can be automatically performed while expanding and contracting the frame 31 of the nozzle device 25.

When the spraying operation by the simple repetitive operation by programming is completed, the carriage 1 is moved, and the automatic spraying by the repetitive operation is performed again. As described above, according to the present embodiment, the worker does not need to step on the scaffold, and can be remotely controlled by the control device at a place slightly away from the spraying place. Therefore, no scaffolding is required, and there is no need to wear protective clothing and masks. At the same time, it is not necessary to interrupt the spraying work by moving the scaffolding, etc., so that the number of workers can be reduced and labor can be reduced.

In this embodiment, the operator performs the operation while visually confirming the spraying operation by the nozzles, as compared with the case where the spraying operation is completely automated. Therefore, even when the shapes of the steel structures to be sprayed are different from each other, the same device can be used without requiring trouble such as changing programming for controlling the operation.
