Description

The present invention relates to a fireproof coating spraying apparatus.

(Prior art) Currently, the semi-dry spraying method is mainly used for spraying refractory coatings. Thus, the operation environment of the semi-dry refractory coating spraying becomes poor due to scattering of materials and the like, which may affect not only the workers but also workers of other types of work around them and, in some cases, even nearby people.

In the case of the wet type, the working environment is favorable without spray material being scattered, but the spread rate is low because the cost is high and the construction efficiency is low. The reason why the construction efficiency is poor is that the weight of the spray gun and the weight of the material are heavier than in the case of the semi-dry type.

For this reason, spraying robots have been proposed to effectively perform the fireproof coating spraying operation.

(Problems to be Solved by the Invention) However, this robot is intended for a semi-dry type fireproof covering material, and since the work itself is performed by the robot, there is no problem for workers, but there is no material scattering prevention device, so the robot is scattered. The fallen material is still cleaned manually, and the work environment problem has not been solved.

Although the robot is fully automated, the robot is not in practical use at present because much labor is required to teach-in the work as full preparation for full automation.

The present invention has been proposed in view of such circumstances,
It is an object of the present invention to provide a fireproof coating spraying apparatus that can efficiently perform a wet type fireproof coating spraying operation and improve the environment of the fireproof coating operation.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a fireproof coating spraying device according to the present invention is provided on a platform mounted on a traveling vehicle via a lifting device, with a wet type equipped with a booster. The lifter comprises a master lifter and a slave lifter on which a refractory coating material spray nozzle is mounted, and a control device for controlling the movement of each nozzle of both lifters on six axes.

(Operation) Since the present invention is configured as described above, the traveling trucks of the master lifter and the slave lifter are moved to a required fireproof coating spraying work site, and the elevating device is operated to operate the elevating device. The nozzle for spraying the wet type refractory coating material mounted on the mounted base is positioned at a predetermined position, and the control device controls the movements of the nozzles mounted on each of the lifters on six axes to control both sides of the member to be refractory coated. The refractory coating work by wet method is performed more symmetrically.
Further, at the time of spraying a steel beam on a wall surface or the like, only the spray nozzle on the master lifter side is operated by the switching operation by the control device.

Further, since a booster is provided for the nozzle, a large-diameter and heavy-weight nozzle is not felt heavy.
By having the degree of freedom of the shaft, it is possible to perform the same spraying operation with front and rear with a light nozzle in response to every movement with respect to the spraying.

(Example) Hereinafter, the present invention will be described with reference to an illustrated example.

(M) is a master lifter, and (S) is a slave lifter, and the gantry (3) is connected to the traveling devices (1) (1 ') via, for example, a pantograph-type lifting device (2) (2').
(3 ') is supported. Each of the frames (3) and (3 ') is equipped with a large-diameter wet-type fire-protective coating material spray nozzle (4) (4') equipped with a hydraulic, pneumatic or electric booster and the like. 4) (4 ') Material supply hose (5)
(5 ') is connected.

A driver's seat (6) is provided on a mount (3) of the master lifter (M), and the master lifter (M) and the slave lifter (S) are operated by operating a control device from the driver's seat (6). It is controlled so as to make a symmetrical movement or to operate only the master lifter (M). Each of the nozzles (4) and (4 ') is controlled by a control device so that X,
The operation is performed with six degrees of freedom in the Y and Z axis directions, around the X axis (Q _x ), around the Y axis (Q _y ), and around the Z axis (Q _z ).

Since the illustrated embodiment is configured as described above,
The operator in the driver's seat (6) operates the traveling device (1), the nozzle (4), and the hose (5) on the master lifter (M) side, and shifts the slave lifter (S) side to the master lifter (M) side. The wet refractory coating material is sprayed on both sides of the steel beam (7) in such a manner as to perform an operation symmetrical to the above.

Thus, as shown in FIG. 2, the nozzle has six degrees of freedom and can respond to any movement by a booster.
The operator can perform the spraying operation with a light nozzle by the same operation as in the past.

As shown in FIG. 3, for the steel beam (9) on the wall (8), the spray mode is switched by the control device from the double-sided blow mode to the single-sided blow mode.
The spraying operation can be performed by the master lifter (M).

 (10) in the figure is a pillar.

(Effects of the Invention) As described above, according to the present invention, the fireproof coating operation is performed using the wet fireproof coating material by the master lifter and the slave lifter mounted with the nozzle for spraying the wet fireproof coating material. The working environment is improved, and the nozzle is provided with a booster, so that a large-diameter nozzle can be used, and the amount of material supplied can be increased. Together with this, the work efficiency is dramatically improved.

Further, since the master lifter and the slave lifter are operated synchronously by the control device or are also operated by the master lifter alone, work efficiency is remarkably improved. The force is reduced.
