Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an asbestos part removal device that automatically removes constructed parts.

"Prior Art" Conventionally, this type of work could only be done manually by an operator. To carry out such work, a diluted diffusion inhibitor made of a surfactant is sprayed 24 hours in advance, and the worker uses a metal spatula-shaped tool or a wire plan-shaped tool to remove the asbestos. Although it is a scraping part, it is designed to be removed with a vacuum cleaner.

It was necessary to double-enclose the work area with plastic film to prevent contamination, and it was also necessary to wear an airline mask while working. The water is drained and washed, and after drying, a surfactant is applied as a fixing solution. Therefore, the scraping operation requires a lot of labor and is very expensive. Some ignorant workers may work without any protection, which can be extremely dangerous.

[Problems to be Solved by the Invention] The present invention provides an asbestos part removal device that can automatically remove asbestos parts and prevent asbestos fibers from spreading.

[Means for Solving the Problems] The present invention is a device for removing asbestos parts of a structure made of sprayed asbestos material, and includes a base that can be moved on the floor by power, and a base that is supported by the base. a main body disposed toward the construction area consisting of an asbestos portion located above; a pressing device that applies a pressing force upward to the main body; and a pressing device provided on the main body and driven by an electric motor to scrape off the construction area. To provide an asbestos partial removal device characterized by including a scraping device that operates to remove debris and a dust collector that filters the debris scraped by the scraping device.

In addition, a plurality of nozzles 59 are provided, and water is supplied from a vibro 0 connected to the pipe 49, and the water is sprayed onto the area that has been scraped for cleaning. The washed water is sent to a dust collector 53 via a vibro 1 branched from the pipe 51 and treated at the same time.

62 is a wiping device, and a recess 63 is formed in the upper surface of the main body 15. A roller 65 consisting of two sponges with a portion extending outward from the surface is rotatably supported in this recess so as to wipe the cleaned surface. Reference numeral 66 denotes a rotatably supported metal roller that makes strong contact with each of the rollers 65 to squeeze out moisture from the rollers 6 and 5. 67 is a pipe for discharging water from the recess 63, and is branched from the vibro 1.

Reference numeral 68 denotes a fixing solution application device that applies a fixing solution made of a surfactant to the surface where the asbestos portion has been removed and the cleaning and wiping portion has been finished. Since this fixer remains active after application, it prevents asbestos fibers remaining for some reason from scattering. O70 is a recess formed on the surface of the main body 15.

Reference numeral 71 designates a plurality of nozzles that eject fixer fluid toward the construction area, and the fixer fluid is supplied from a tank 72 via a pump 73, a hose 75, and a pipe 76.

A sponge roller 77 is arranged in the recess 70 and rotatably supported, and is used to press the sprayed fixing liquid uniformly. Reference numeral 78 denotes a rotatably supported metal roller that makes strong contact with this roller, and squeezes out the fixing liquid from the sponge. The fixing liquid accumulated in the recess 70 is transferred to the tank 7 via a pipe 80 and a hose 81.
2 and can be used repeatedly.

Numerous slits 82 are formed on both sides of the surface of the main body 15 and in the vicinity of the scraping device 28, 83 is a bottom plate that covers the bottom of the main body 15, and 85 is a pipe 8 that opens through this bottom plate.
A hose 87 connected to 6 is a dust collector that sucks the air inside the main body 15 through this hose and filters it with a heper filter. This dust collector sucks air through the slit 82 and prevents dust and the like from coming out from the vicinity of the scraping device 28 of the main body 15. Moisture coming out of the dust collector 87 is stored in the tank 56.

Reference numeral 88 denotes a pipe that branches into many parts and passes through the bottom plate 83, and a nozzle 90 is provided at the upper end of each branched part, so that water is supplied from the pump 46 through a valve 91 and a hose 92. ing. This water supply is carried out to clean the inside of the main body 15 after the work is completed, and is carried out while the dust collector 87 is being driven.

When performing construction with the structure as described above, the asbestos partial removal device is appropriately arranged and the fluid pressure operation device 16 is installed.
to raise the main body 15. In this case, the attachments attached to the main body 15, such as the blade 18 and the scraping device 28,
When the main body 15 comes into contact with the main body 15 and is pressed with an appropriate force, the rising of the main body 15 stops. Next, the electric motors 12, 33, 42 and pumps 26, 46, 73 are driven, and the dust collectors 37, 53 are driven.
．． 87 is driven to advance the base 10 and remove the asbestos portion. When the base 10 reaches the end, the main body 15 is lowered, the base 10 is moved appropriately by hand, and the same operation is repeated.

Various modifications can be made to the embodiments of the invention. For example, the blade 18, the cleaning device 57, the wiping device 62, the fixer coating device 68, and the parts attached thereto may be omitted, and only the scraping device 28 and devices attached thereto may be provided. In such a case, the other parts may be processed in a conventional manner. Further, it is also possible to make a modification such as rotating a highly rigid wire brush to scrape without providing the spiral scraping member 31 of the scraping claw device 28. In addition, the main body 15 has three or more supports 1
Although it is preferable that the support be supported by four supports, it may also be configured to be supported by only one support.

The asbestos part removal device according to another embodiment of the present invention shown in FIG. 4 is used only to scrape off asbestos parts such as almost horizontal ceilings, and is pressed upward by a fluid pressure operating device (not shown). The main body 15 is fixed to the upper end of the supporting column 14. The main body has a circular upper end and a hollow interior, and is provided with a scraping claw device 28 driven by an electric motor 93 via a shaft 94. This scraping claw device has a scraping plate 97 in which a scraping member 95 of a certain degree of rigidity made of a plurality of elastic metal plates and a scraping member 96 of a wire brush are attached alternately in a radial manner. A plurality of holes 98 are provided so that vacuum suction can be carried out through a hose 99 from a dust collector (not shown).

Therefore, the scrapings will be sucked in. 100
This is a plan-shaped flock made of synthetic resin or the like embedded in the upper end of the main body 15 to prevent asbestos fibers from scattering. When using such a device, a diffusion preventive agent may be sprayed on the construction area 17 24 hours in advance, and after the work, the area is washed with water, dried, and then a fixing agent is applied. In this embodiment, if necessary, a means is provided for fixing the main body 15, which is rotatably fixed around the upright axis of the support 14, so that it can be tilted to the support 14 about an axis horizontal to the support 14, so that the structure can be constructed in an inclined manner. It is also possible to perform the work of the department. Scraping work can be done by attaching a mounting plate with only a rigid scraping member attached to it and a removing board with only a flexible wire brush-like scraping member attached, which can be exchanged. C,
It may be configured to spray water onto the area where the scraping operation is to be performed.

[Effects of the invention] The invention has the effect of significantly reducing labor and costs.
