Enclosure type booth for ultrahigh pressure washer DETAILED DESCRIPTION OF THE INVENTION The present invention is applied, sends outside air intake fan from the ceiling, the steam generated in the washing and stripping operations with air exhaust fan underfloor It is configured to contaminate contaminants such as jet drainage, oil and paint fragments generated during cleaning and peeling work in the separation tank under the floor, and contaminate the above-mentioned work environment due to the operation of the ultra- high pressure washer. The problem with
That it has been eliminated all.

Further, it attached rectifying plate made of punching metal to entire ceiling surface of the enclosure type booth, the flow rate One one or equalizing the by rectifying the flow of air in the enclosure type booth, 0.5 m /
Seconds Ru also possible and Do Ttei be below. Ultra of such a configuration
Ultra high pressure gun of the present invention to be used in the enclosure type booth for high pressure washer is attached to the distal end of the balance hand through left and right pivot angle restricting jigs and vertical swing angle regulation jig, the rear end of the balance hand Attached to the three-dimensional movement mechanism via a parallel axis rotation restricting jig, and equipped with a protective plate near the mounting location of the ultra-high pressure gun, so that smooth cleaning and peeling work can be performed, Safety for workers can be sufficiently ensured.

FIG. 1 is an overall perspective view showing a partially cutaway booth 13 for an ultra-high pressure washer in which the ultra-high pressure gun of the present invention is used , and FIG. 2 is an ultra- high pressure gun 3 of the present invention. FIG. 5 is a perspective view showing a state of attachment to the balance hand 2. That is, in FIG. 1, reference numeral 1 denotes an automobile paint truck which is a part to be processed, 2 denotes a balance hand supporting an ultra-high pressure gun 3 of an ultra-high pressure washer, 4 denotes a worker, and 5 denotes a ceiling booth of an enclosed booth. Three intake fans are arranged in the drawing. Reference numeral 6 denotes an exhaust fan which exhausts the air in the enclosed booth from under the floor of the booth to the outside of the enclosed booth through an exhaust duct 14.
Reference numeral 7 denotes an expanded metal on which a component to be processed is placed, which constitutes a part of the floor 16 having a double structure. 8 is gallery,
Reference numeral 9 denotes a rectifying plate made of punched metal adhered to the lower surface of the ceiling 17 and also functions as a rectifying mechanism for intake air by the intake fan 5.

The current plate 9 made of punching metal is
Diameter 8 for general structural steel sheet (SS400) with thickness of 2.3mm
The punched holes of 10 mm are drilled at a pitch of 10 mm. 10 the separation tank, 11 carrying the part being processed, shea catcher Limiter for unloading, is 12 gutter 15 is discharged trough. The white arrows indicate the direction of the outside air flow in the enclosed booth.

As shown in FIG. 2, the ultra-high pressure gun 3 is attached to the tip of the balance hand 2 via a left-right turning angle regulating jig 18 and a vertical swing angle regulating jig 19.
The tip of the ultra-high pressure gun is not aimed at the operator. The rear end of the balance hand 2 is connected to a three-dimensional moving mechanism 20 via a parallel-axis rotation restricting jig 21.
To prevent entanglement.

The three-dimensional moving mechanism 20 includes a main body swivel 22,
Main body 2 pivotally supporting one end of parallel link 23a, 23b
4, a bracket 25 for pivotally supporting the other ends of the parallel links 23a and 23b, and a spring 26 connected between the parallel link 23b and the main body 24 reduces the driving force for the vertical operation of the balance hand 2. ing. The main body 24 is configured to be able to rotate indefinitely by the main body swivel 22, and the main body swivel 22 is fixed to an overhead traveling carriage (not shown) or the like.

A transparent protective plate 30 is attached to the tip of the balance hand 2 to which the ultrahigh-pressure gun 3 is attached, and cuts off between the worker 4 and the parts to be processed. As a matter of course, the protective plate 30 has an opening 31 that allows the ultrahigh-pressure gun 3 to swing left and right and swing up and down. The transparent protective plate 30 may be a plastic plate such as an acrylic plate or a safety glass having a scattering prevention function, but the present invention is not limited thereto.

Although not shown, an emergency stop button for urgently stopping the ultra-high pressure washing operation is provided at a specific location of the balance hand 2 close to the ultra-high pressure gun 3, and the activation of the ultra-high pressure gun 3 is made a double trigger. The safety can be further enhanced by taking into account the fact that the operation is performed. By using ultra high pressure gun of the present invention having the above configuration will be described using an example of a work of peeling away the paint adhering to the automobile painting trolley.

[0014] The shutter 11 of the enclosed booth 13 is opened, and the automobile coating trolley 1 to which the paint to be processed is adhered is carried into the enclosed booth 13 and the double-structured floor 1 is opened.
After being placed on the expanded metal 7 constituting a part of 6, the shutter 11 of the enclosed booth 13 is closed. Next, the intake fan 5 and the exhaust fan 6 are operated to make the air in the enclosed booth circulate. As a result, the air in the enclosed booth is divided into an intake fan 5, a flow straightening plate 9 made of punching metal, a slit of expanded metal 7,
Exhaust duct 1 passes through heavy structure floor 16 and exhaust fan 6
Distribution channels for evacuating the outer enclosure type booth 13 through 4 Ru is configured <br/> formed.

In this state, the operator 4 freely drives the ultra-high pressure gun 3 of the present invention held by the balance hand 2 to proceed with the work of peeling off the paint adhered to the automobile paint truck 1. Since the balance hand 2 is maintained in an equilibrium state by the spring 26, the movement of the balance hand 2 in the vertical direction is realized with a very small driving force. The rear end of the jig 21 is restricted to a rotation range in the direction of arrow A, for example, within 360 ° by the parallel-axis rotation restricting jig 21, so that the ultrahigh-pressure hose 3a is prevented from being entangled with the kink phenomenon. Not only can the ultra-high pressure hose be completely free from damage, but also smooth operation can be realized. In addition, the movement of the ultra-high pressure gun 3 is regulated to a turning angle of, for example, 90 ° by the right and left turning angle restricting jig 18 and to a 45 ° turning angle by the vertical turning angle restricting jig 19, for example. The tip of the high-pressure gun can be prevented from facing the operator, and the safety is further improved.

A part of the mist of the water vapor and the contaminants generated during the operation flows through the air flow from the ceiling 17 to the double-layered floor 16 according to the above-mentioned distribution route.
It is sucked by the exhaust fan 6 through the gallery 8 under the floor from the slit of the expanded metal 7 on which the automobile paint truck 1 is placed, and is released from the exhaust duct 14 to the atmosphere. The paint drainage and the peeled paint piece enter the gutter 12 through the gallery 8 and the slit of the expanded metal 7 on the floor surface, further enter the separation tank 10, and are separated into the spray drainage and the peeled paint piece, and peeled off. The paint pieces are sealed in the separation tank 10.

The jet drainage and the like separated in the separation tank 10 are discharged to the outside through a discharge gutter 15. By rectifying the rectifying plate 9 made of perforated metal on the entire surface of the ceiling 17 of the enclosed booth 13, a rectifying effect in which air flows uniformly downward inside the enclosed booth 13 is obtained.
The flow velocity of the air inside can be set to 0.5 m / sec or less.

Further, the protective plate 30 (800 mm × 500 m
m, a transparent acrylic plate having a thickness of 5 mm) can protect workers.

[0019]

As described above, according to the ultrahigh-pressure gun according to the present invention.
For example , smooth washing can be performed while maintaining the same working speed as before.
In addition to being able to realize the cleaning / peeling work, the mounting structure has a restricted movement, and the provision of a protective plate can further improve the safety for workers.
