Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is particularly useful when repainting the top and bottom surfaces of a metal folded plate roof such as a polymeric type.
To provide a scraper that can remove folded plate roofs simply, quickly and reliably without damaging the surface of the roof.

[Conventional technology and its problems]

Conventionally, when repainting the surface of a folded metal roof, a worker would scrub the surface with a wire brush to remove the paint film. However, with this method, it takes an extremely long time to work over a wide area of the surface of a folded-plate roof, and it is especially time-consuming to work on a wide area of the surface of a folded-plate roof. In such cases, there are not only horizontal places but also sloped places, and even in the horizontal places, the height is different between the high top of the mountain and the low bottom. There is a difference, and it is extremely difficult to work with.
There were problems such as an even greater burden on the workers.

Also, if you use a rotary disc sander to polish the surface of a folded-plate roof and remove the coating, the efficiency will be doubled compared to using a wire brush, but the pressure applied to the folded-plate roof will be too strong. This will also remove the inner layer of the folded plate roof (for example, the Fe in galvanized iron plates), which may lead to early rusting or, in the worst case, create holes in the metal plate of the folded plate roof. There was a serious problem.

Similar problems occur when working with a wire brush while applying strong pressing force.

As mentioned above, removing the paint film from the surface of a folded-plate roof can take a long time and is tiring, making it extremely difficult to remove just the paint film while keeping the pressing force of the disc sander constant. There was a problem.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor has devised the present invention by installing a cup-shaped pedestal on the inside of the pedestal for the inclined part on both sides of the cart, which has wheels on both sides in the front and rear and width directions. A cleaning brush for the inclined part is rotatably provided to form the cleaning part for the slope, and a cup-shaped cleaning brush for the top is rotatably provided on a substantially horizontal plane on the lower surface side of the top pedestal at the upper part of the cart. A cup-shaped bottom cleaning brush is provided on the bottom side of the bottom pedestal at the bottom of both sides of the cart so as to be rotatable on a substantially horizontal plane. A cleaning machine may be provided in which a motor drive unit for appropriately rotating the cleaning brush and the bottom cleaning brush is provided, and the pedestals for both inclined portions are formed in a symmetrical substantially V-shape on both sides in the width direction of the cart, or in the above configuration, The part of the pedestal for both slopes where the cleaning brush for sloped parts is installed can be slid vertically, and the cleaning brush for sloped parts can be moved up and down by swinging the operating rod part of the handle with an operating rod installed at the rear of the cart. Or, in the above-mentioned structure, the pedestal for both inclined parts can be made swingable on the vertical plane in the width direction of the cart, and can be fixed at an appropriate slope. By making the scraping machine movable in the width direction of the cart, the scraping parts for both bottom parts can be easily removed, especially when repainting the mountain parts of metal roofs such as folded plate roofs.

The metal roof can be removed quickly and reliably without damaging the surface of the metal roof, thus solving the above-mentioned problems.

〔Effect of the invention〕

First, in the invention described in claim 1, wheels 2, 2. Trolley A equipped with...
Cup-shaped slope part cleaning brushes 7.7 are rotatably provided inside the slope part pedestals 3.3 on both sides to form the slope part cleaning part B, and the top pedestal 10 is attached to the upper part of the carriage.
A cup-shaped top cleaning brush 11 is provided rotatably on a substantially horizontal plane to form a top cleaning part C on the lower surface side of the car. A cup-shaped bottom cleaning brush 15.15 is provided rotatably on a substantially horizontal plane to form a bottom cleaning part 1, and these cleaning brushes 7 for the inclined part and the top cleaning brush 11 are provided.
, motor drive units 8, 13, and 18 for rotating the bottom part holder 15 according to jM are provided, respectively, and the inclined part pedestal 3,
3 is a kerating machine formed in a substantially V-shape symmetrically on both sides of the cart A in the width direction, firstly, the kerating work can be done easily and quickly, and secondly, it can prevent damage to the folded plate roof E. It has the effect of being able to do cleaning work without having to give it.

To explain these effects in detail, in the first aspect of the invention, the cart A is provided with a slope part B, a top part C9 and a bottom part, each of which is rotatably provided with a cleaning brush for the slope. 7. Cleaning brush for the top 11. The bottom cleaning brush 15 is rotated by the motor drive unit 8, 13, 18, and the cleaning machine of the present invention is placed so as to straddle the mountain part 19 of the folded plate roof E, so that the slope part 19a on both sides of the mountain part 19 is removed. , 19a is the cleaning brush 7° for the slope,
7, the top part 19b of the mountain part 19 is coated with the top scrubbing brush 11, and the bottom part 20.20 is coated with the bottom scrubbing brush 1.5.15 to easily and quickly coat each part of the folded plate roof E at the same time. can be removed.

Furthermore, wheels 2, 2. ... is provided, the folded plate roof El can be easily moved, and the paint film can be removed over a wide range extremely simply and quickly.

Conventionally, the so-called scouring process for removing old paint film from the surface of metal folded plate roofs involved applying a wire brush to the surface of the folded plate roof and scrubbing to remove the paint film. Roofs require an extremely large amount of time and labor, especially in the case of polymerized folded plate roofs.
Because there are mountainous areas and not only horizontal areas but also sloping areas, manual cleaning work is required.
This made it more difficult and troublesome, reducing work efficiency. However, with the keren machine of the invention, folded plate roof E
By being able to easily and quickly clean the 19 peaks, the labor and time required for conventional cleaning work can be reduced at once.

Next, the top cleaning brush 11. Bottom cleaning brush 1
5 is at a predetermined position with respect to the cart A, so when the cleaning machine of the present invention is placed so as to straddle the peak 19 of the folded plate roof E, the top cleaning brush 11. The bottom cleaning brush 15 can maintain substantially constant ground pressure (pressing force) on the top 19b and bottom 20 of the mountain portion 19, respectively, and the slope cleaning brush 7.7 is also provided in a V-shape in the width direction of the truck A. Since it is rotatably provided on the pedestals 3, 3 for inclined parts, the cleaning brush 7.7 for double-ended inclined parts can be attached to the double-ended inclined parts 19a, 1 of the mountain part 19.
Since it can be grounded roughly along line 9a, by operating these simultaneously, it is possible to remove the coating film of the folded plate roof E such as the polymer type with an approximately even thickness, and avoid excessive scraping during the cleaning work. Therefore, damage to the surface of the folded plate roof E can be prevented.

In other words, in the past, such cleaning work required the worker to
The coating was removed by rubbing a wire brush on the roof or using a rotary disc sander to polish the surface of the folded plate roof, so it was difficult to rub or press it against the folded plate roof. If the pressure is too strong, it will not only remove the paint film but also damage the metal plate body (F) of the folded plate roof.
(e, etc.), causing rust to develop on the roof surface very early, and in the worst case, causing serious problems such as making holes in the metal plates of the folded-plate roof. was there. This happens because it is extremely difficult for workers to manually use a wire brush or disc sander for long periods of time with a constant pressing force, but the sanding machine of the present invention , by adjusting the grounding conditions of the slope part cleaning brush 7°7, the top cleaning brush 11, and the bottom cleaning brush 15, 15 to the folded plate roof E, or by making the ground pressure almost constant,
Conventional problems can be solved all at once.

Next, in the invention set forth in claim 2, in the invention set forth in claim 1, the portion of the slope portion pedestal 3゜3 where the slope portion cleaning brush 7.7 is provided is slidable in the vertical direction. By using a cleaning machine in which the cleaning brush 7.7 for the slope can be moved up and down by swinging the operating rod part 9b of the handle 9 with an operating rod provided at the rear of the truck A, the mountain of the folded plate roof E can be removed. Even if the height of the sloped part 19a of the part 19 is higher than the diameter of the sloped part cleaning brush 7, it is possible to completely contact the sloped part 19a by swinging the sloped part cleaning brush 7. This allows for extremely orderly cleaning work.

That is, the height of the mountain portion 19 of the folded plate roof E may be high depending on the type, and the slope portion 19a may also increase in size in the height direction and become larger than the diameter of the cleaning brush 7 for the slope portion. However, in the present invention, by making the portions of both slope portion pedestals 3, 3 of the slope portion cleaning portion B slidable in the vertical direction where the slope portion cleaning brushes 7.7 are provided, the slope portion cleaning brushes 7. .7 is the double-ended oblique part 19a of the mountain part 19
.

This inclined portion 19a can be moved along the height direction of the inclined portion 19a.
, 19a can be reliably cleaned in the height direction. Further, the upward and downward movement of the cleaning brush 7.7 for the inclined portion is performed by swinging the operation rod part 9b of the handle 9 with the operation rod.
Since it is interlocked with the operation of the sloping part cleaning brush 7, it is possible to easily move the slope part cleaning brush 7 in the vertical direction by simply operating the operating handle 9 from the rear of the cart A.

The other constituent elements are the same as those in the above-mentioned item 1 invention, and the same effects can be achieved.
