A sealing means made of a transparent material that covers the entire surface, a gripping means that is fixed to a portion of the removing means that is not covered by the sealing means and that is partly configured as a handle that can be gripped by an operator, and one end Is composed of suction means consisting of a suction flexible tube, which is hermetically connected to a suction port drilled in the sealing means, and the other end is connected to a compressor, and the removing means is a polishing disk. A grinder serving as an action portion, and a wire rod serving as a seal member includes a first seal member in which a plurality of rigid and flexible wire members are closely planted, and a first seal that is closely planted adjacent to the first seal member. hand The second sealing means is composed of a plurality of wires that are slightly thinner than the first sealing means and slightly longer than the first sealing means, and the gripping means or the sealing means can be illuminated in the vicinity of the rotating disk for polishing of the working portion of the removing means The present invention relates to an asbestos removal tool that is equipped with a lighting device .

  In recent years, damage caused by asbestos that has been used in many buildings has been widely reported, and construction for removing asbestos from buildings has been actively carried out. However, the removal of asbestos is a risky construction, and workers are always exposed to the risk of sucking asbestos dust. For this reason, a method has been adopted in which the asbestos that has been rigorously hardened with protective clothing, tightly shielded the room under construction, and peeled off and deposited on the floor is sucked with a suction device. However, the conventional method of removing asbestos with a remover (a tool like a spatula) called “Kelen” held by the worker and cleaning and sucking the asbestos pieces that have fallen on the floor inevitably causes the asbestos powder to scatter in the room. In addition, there is a high possibility that the worker will accidentally suck. In addition, the work of completely sucking the asbestos powder scattered in the room is troublesome, and the protective clothing is also contaminated with the asbestos powder. In this way, asbestos peeling work has many difficulties, but this work must be continued until all asbestos is completely removed from all buildings in Japan. A lot of back-to-back work continues.

  In view of the circumstances as described above, various inventions and devices have been made so that asbestos removal work can be performed more rationally and safely. Those listed in Patent Documents 1 to 3 below are some of them. Among these, the “asbestos floor tile removing device” of Patent Document 2 below is a peeling device dedicated to asbestos as a flooring material, and “the removal method of buried asbestos pipe and device therefor” of Patent Document 3 below are embedded Method and apparatus limited to removal of asbestos tube. Therefore, here, the “asbestos removal apparatus, removal head, and removal tool” of Patent Document 1 described below, which seems to have the highest degree of sharing the gist and purpose of the present invention, will be described in detail.

Patent Document 1 “Asbestos removal device, removal head, and removal tool”
Is a large-scale device composed of a movable carriage, a multi-joint arm pivotably provided on the movable carriage, a removal head provided at the tip of the multi-joint arm, and a collection unit for collecting asbestos. The asbestos removal tool is used to remove the asbestos and to spray the foam made of the drug to suppress the powdering of the asbestos, and to suck and collect the asbestos. The periphery of the removal head is sealed with a brush seal in which thin fibers made of nylon or the like are bundled.

  The removal device or the removal tool of Patent Document 1 tries to avoid the worker from being directly exposed to the asbestos powder by separating the working part for peeling asbestos from the worker's hand by the articulated arm and the removal head. However, in order to realize the configuration, there are many challenges. One of them is that it requires a large moving carriage. In actual asbestos peeling sites, it is extremely rare to have a flat surface that can move a moving carriage smoothly, and there are severe irregularities, scattering of articles and demolition waste, and large movement with wheels. In most cases there is no space to move the carriage. Even if the movable carriage can be installed, it is considered that there are few cases in which the removal head can be pressed against the desired peeling target surface by expansion and contraction of the articulated arm. In the actual site, it is the present situation that the high part has a scaffolding and the worker rides on the scaffold and peels off, but supports the articulated arm that reaches the high part such as the ceiling of the gymnasium, for example Considering a moving carriage, it is understood that it is very large and unrealistic.

  Further, in an actual asbestos peeling site, asbestos adhesion is generally slightly different even on the same plane. If the thickness and adhesion of the asbestos layer are different, some or most of it may be peeled off, and there may be another layer of material between the asbestos layer and the enclosure. A uniform mechanical peeling action has little effectiveness. In addition, if the surface to be peeled is a perfect plane, there are few cases, and there are subtle irregularities and curves, and beams are protruding. Therefore, it is not possible to remotely remove the asbestos by remotely operating the removal head attached to the tip of the articulated arm against the surface to be peeled that shows such a variety of aspects. However, even if it can be used to some extent, asbestos remains in a considerable amount in various states, and as a result, the residual asbestos must be peeled off manually by workers.

  Further, in Patent Document 1, since the entire removal head is covered with an opaque case, the degree of asbestos removal cannot be confirmed with the eyes of an operator unless the removal head is moved. As described above, since the surface to be removed has various aspects, the worker is currently carrying out the removal work while confirming the removal state with his / her own eyes, but the removal head itself is opaque. In the state covered with the case, this confirmation work cannot proceed simultaneously with the removal work, which is a major obstacle to the progress of the removal work.

Patent Document 1 also discloses a method of injecting a foam of a drug in order to avoid asbestos powdering. Although this method is also used in the current manual operation, in the removal device or removal tool of Patent Document 1, this method is likely to cause a new obstacle in practice. That is, in the removal apparatus or removal tool of Patent Document 1, the periphery of the removal head is sealed with a brush seal. However, when no chemical foam is used, even if asbestos is powdered, Since the suction action of the recovery means works, the external air flows in from the brush seal, and the possibility that the asbestos powder leaks out from the brush seal is low. However, if the powder is surrounded by the foam of the medicine, the foam of the medicine remains attached to the surface to be removed, and leaks to the outside from the brush seal by the movement of the removal head. Since the drug foam contains asbestos powder, asbestos powdered by drying of the drug foam will be scattered in the air unless the adhered drug foam is completely removed, which is counterproductive. End up. In addition, the recovery means sucks asbestos surrounded by the foam of the drug, and it is imagined that the recovery hose and the internal mechanism of the recovery means are filled with highly viscous recovered material, resulting in malfunction. Not difficult. Therefore, the method of surrounding asbestos with a foam of medicine is effective to some extent in the current manual peeling, but it is very impractical to suck it mechanically. I don't get it.

From the above, the problems to be solved by the present invention are set as follows.
<Problem 1>
It is difficult to mechanize or automate asbestos removal work in view of the situation of asbestos removal work and the current situation that the surface to be removed is not uniform, but even if it can be mechanized or automated, Asbestos always remains on the surface to be removed. Therefore, asbestos removal work is not based on the direction of mechanization or automation, but based on a detailed removal method by current workers, which can respond promptly to the on-site situation, and further reduce the risk and burden on workers as much as possible. Develop a removal tool that can perform rational and efficient removal.
<Problem 2>
In order to prevent accidental suction by workers, it is desirable that the removed asbestos can be completely sucked in the sealed space of the removal tool. At this time, for the purpose of facilitating the operation of the suction device, when considering asbestos powdered and sucked, if it is covered with a drug foam, it will cause a malfunction of the suction device as described above, or from the seal On the contrary, there is a high possibility of leaking. Therefore, we do not take the method of coating with the foam of the drug, but develop a configuration that aspirates asbestos as powder as completely as possible. At this time, if the removed mass of asbestos is large, smooth suction may be hindered even if it is not viscous with the drug, or it may cause a malfunction of the suction device. Like that.
<Problem 3>
The confirmation of whether or not asbestos has been completely removed is basically determined by the operator with the eyes. Therefore, the working part itself from which asbestos is removed must be configured so that an operator can always easily check with eyes. In addition to this, the problem of the lighting device is also important. The asbestos removal work site may or may not have a lighting device. Further, even if there is an illumination device, it is often a shadow depending on the location of the removal target surface, and the removal target surface is often not seen well, so the illumination device always illuminates the removal target surface. It is desirable that there is.

The present invention has been made to solve the above-described problems, and provides the means for solving the problems described below.
<Solution 1>
A removing means for removing the asbestos surface, a sealing means made of a transparent material that has a sealing means made of a plurality of wires densely planted in a portion in contact with the asbestos surface and covers the entire working part of the removing means, and a removing means The gripping means is fixed to a portion not covered by the sealing means and a part of the gripping means is configured as a handle that can be gripped by an operator, and one end is hermetically connected to a suction port formed in the sealing means. The suction means is composed of a suction flexible tube connected to the compressor at the other end, the removing means is a grinder having a rotating disk for polishing as an action part, and the wire material as a sealing means is rigid. And a plurality of flexible wire rods densely planted, and a plurality of wire rods of the first seal means closely adjacent to the first seal device and slightly longer than the wire rod of the first seal device Book line Consists second sealing means consisting of the gripping means or sealing means, asbestos removal tool, characterized in that the illuminating device is installed which can illuminate the vicinity of the rotary disk for abrasive action part of the removal means.
<Solution 2>
When the axial direction of the rotary shaft of the rotary disk for abrasive action part of the removal means and the vertical direction, the tip portion of the sealing means made of a transparent material is formed on an angle of less than 90 ° in plan view The asbestos removal tool according to Solution 1, which is characterized.

  The present invention, in the asbestos removal work, while maintaining the fine removal work method that has been conventionally performed by the hand of the worker as it is, it is easy for the worker to use, is efficient, and there is a risk to the worker. It provides an asbestos removal tool that is kept as low as possible.

  First, the work that has been performed by a worker using a spatula-shaped tool called keren has been considered to be replaced with electric appliances to some extent to improve the efficiency of the removal work. At this time, what is most important is a removing means that directly touches the asbestos surface to peel and remove it. In other words, asbestos can be peeled and removed efficiently with the least burden on workers. Moreover, it is important that asbestos can be removed not as a large lump but as a powder because of the above-mentioned problems. As a result of experimenting with various types of tools in search of the removal means having such a function, a small grinder for home use was reached as the most suitable one for the above purpose.

  Small grinders for home use are commonly found in home centers (mass retailers such as do-it-yourself tools) in recent years as Sunday tools. The structure is very simple, and a rotating disk for polishing is mounted downward at the tip of the handle portion incorporating the motor. When the switch is turned on, the disk rotates at high speed. The rotating disk for polishing is made of a grindstone, and various kinds of roughness are prepared and can be easily exchanged. There are also rotating discs dedicated to polishing concrete surfaces.

  A good point of this small grinder is that it has a function and effect that are just right for the purpose of the present invention to pulverize and remove asbestos. When the rotating disc for polishing a small grinder is applied to the asbestos surface, the asbestos surface is finely powdered and peeled off. Any thickness of asbestos can be accommodated by inserting a rotating disk deeply into a thick asbestos surface and shallowly rotating a rotating disk into a thin asbestos surface. In addition, the various aspects of the hardness of the asbestos surface, the asbestos surface covered with something, or the surface of another material underneath the asbestos surface can be reduced by simply changing the roughness of the grindstone of the rotating disk. It turns out that it can respond. There are many types of grindstones for rotating disks, but it is a great merit that various kinds of these abundant rotating disks can be used by using a small grinder as the main body of the removing means.

  Another feature of small household grinders is that they are designed to be extremely compact and lightweight. The asbestos removal tool is always held by the operator during the removal work. Especially when removing asbestos from the ceiling surface, the asbestos removal tool is turned upside down and the ceiling is lifted with the hand raised. The removal work must be continued against the surface. Therefore, the basic condition of the removal tool is required to be as light and compact as the removal performance. However, small household grinders are perfect for this purpose because they are designed to be extremely compact and lightweight so that even women can use it for do-it-yourself. In addition, small grinders for home use are, of course, constructed to operate with a 100V AC power supply that is usually drawn into any home, but this point is also great for removing asbestos. It will be an advantage. In other words, since a 100V AC power supply is installed in almost all buildings in Japan, it is not necessary to prepare a special power supply device for removing asbestos. This is a great advantage in terms of work mobility and cost.

  Therefore, the configuration of the present invention is based on a small grinder for household use as the removing means, and the rotating disk for polishing the grinder, that is, the action part of the removing means is shielded by the sealing means to be pulverized. Asbestos was made so that it was not scattered. Specifically, a rotating disk for polishing a small grinder is covered with a synthetic resin covering as a sealing means, but at that time, the rotating disk that serves as the working part of the removal work can always be visually confirmed. In addition, a transparent synthetic resin was used as the cover.

  Further, as a sealing means for sealing a portion where the covering member of the sealing means is in contact with the asbestos surface, a plurality of wires are densely planted in a brush shape so that asbestos powder does not leak outside the sealing means. The reason why the sealing means is a bundle of wires is to ensure that air flows in appropriately from between the wires densely planted in a brush shape when the inside of the sealing means is depressurized by suction by a compressor described later. . Accordingly, an air flow is always generated from the outside toward the inside of the sealing means in the sealing means portion, and the powder of asbestos is pushed back into the sealing means by this air flow and does not leak to the outside. . The material of the wire is not particularly limited as long as it has both rigidity and flexibility. Specifically, a wire made of synthetic resin such as nylon fiber, polyester fiber, acrylic fiber, horse, etc. It is possible to use animal hairs, and metal wires having rigidity and flexibility such as brass and stainless steel.

  Another reason for using a plurality of wire rods as the sealing means is that the surface to be removed is not necessarily smooth, and a state in which there are irregularities and curves is normal. That is, if the sealing means is, for example, in a packing shape, a gap is always formed when it is applied to a surface with unevenness or a curve. However, if the sealing means has a plurality of wires, the entire sealing means is well adapted to the uneven surface and the curved surface due to the flexibility of each wire, so that no gap is generated. In addition, when the operator presses the entire removal tool against the surface to be removed, it is also a great feature that the sealing means of the plurality of wire rods bends to serve as a cushion, and the operator's work becomes extremely easy.

  Further, as a dense planting structure of a plurality of wires of the sealing means, a second sealing means made of a plurality of slightly longer and thinner wires is implanted around the first sealing means made of a plurality of slightly thicker and shorter wires. Thus, it is possible to provide a characteristic that is not found in the sealing means composed of only a plurality of wires having a single thickness and length. That is, the first sealing means composed of a plurality of slightly thicker and shorter wires is mainly responsible for maintaining a certain degree of sealing performance and rigidity of the entire sealing means, so that the operator applies excessive force only to one end of the removal tool. Even if it has a repulsive action, excessive inclination of the entire removal tool is prevented. Also, when the operator excessively presses the entire removal tool against the surface to be removed, the entire removal tool is stopped at a fixed position by the rigidity of the first sealing means, and as a result, the removal means penetrates the asbestos layer. This prevents malfunctions that would cut down to the surface of the chassis. On the other hand, the second sealing means composed of a plurality of slightly longer and thinner wires is mainly responsible for flexibility and high-level sealing performance, and at the same time increases the sealing performance that is insufficient with only the first sealing means, and at the same time, cushioning action This reduces the reaction felt by the operator, so that the feeling of work becomes very good. This is a very important point because the present invention is a work that is performed by an operator holding the hand for a long time. In general, the second sealing means has a higher planting density than the first sealing means.

Next, the front end portion of the sealing means is configured to have an angle of 90 ° or less in plan view. This point also works extremely effectively for increasing the working efficiency. That is, by configuring the tip of the sealing means at an angle of 90 ° or less in a plan view, the entire sealing means can be formed into a substantially right triangle shape in a plan view, and at the corner portion of the asbestos surface that is the surface to be removed. Contact very properly. In the configuration of the present invention, it is important to bring the grinder rotating disk as the removing means as close as possible to the two sides constituting the corner portion at the corner portion of the asbestos surface. This can be achieved by forming a substantially right triangle. If the angle of the tip of the sealing means is too small, the rotating disk of the grinder is far from the corner of the asbestos surface, so the minimum value of the angle of the tip of the sealing means is considered to be about 80 °. That is, if all the corners of the work site are completely 90 °, the tip of the sealing means can be limited to 90 ° in plan view, but the corners may not be completely 90 ° depending on the situation of the site. There are many. Therefore, as a configuration that can cope with the case where the corner portion is slightly narrower than 90 °, it is conceivable that the angle of the front end portion of the sealing means is 90 ° to 80 °. It should be noted that it is sufficiently conceivable to set the angle of the tip of the sealing means to 80 ° or less for a site where there are obviously sharp corners. In this case, the minimum value will be about 30 ° considering the balance of the configuration with other parts.

  In one embodiment of the present invention, the gripping means that the operator grips with the hand, that is, the tip portion of the handle portion is inserted into the sealing means made of transparent resin, and the removal means is polished at the tip portion. An illuminating device that can illuminate the vicinity of the rotating disk for use is mounted. Thus, the operator can continue the operation while constantly monitoring the situation in which the polishing rotating disk is cutting the asbestos surface. This point is extremely important. In other words, as described above, the asbestos surface has an infinite manner depending on the thickness, hardness, relation to other layers, and the peeling state, and even on the same surface, the manner varies depending on the location. Therefore, it is necessary to finely adjust the depth and traveling direction of the rotating disk by operating the handle while constantly monitoring the cutting state of the rotating disk. At the work site, there are places where it is difficult to reach the illumination as described above depending on the work site. However, if the lighting device can always clearly grasp the cutting status of the rotating disk, the worker can efficiently use it without waste. You can proceed to work.

  A further feature of the present invention is that asbestos is pulverized and this is airtightly connected to a suction port having one end drilled in a sealing means and the other end is connected to a compressor by a suction flexible tube. The point is to remove by suction. That is, the powdered asbestos is all sucked by the suction flexible tube and does not contaminate the outside air. For this reason, in the present invention, as usual, there has been no measure of enveloping asbestos with the foam of the drug. In other words, the method of wrapping asbestos with the foam of the drug will cause the viscous performance to deteriorate significantly because the viscous mass passes through the inside of the suction flexible tube, and in some cases, the suction action itself may be hindered. Is also possible. Furthermore, as described above, the drug foam containing asbestos leaks from the wire rod of the sealing means and eventually remains on the surface to be removed. Therefore, although it is the opposite of the normal idea, we considered as a basic policy that asbestos was pulverized as much as possible, and this was completely aspirated under the condition that the suction means and the sealing means were fully acting. . All the configurations of the present invention are configured in accordance with this basic policy, including the removing means, the sealing means, and the sealing means of the sealing means.

According to the invention of Solution 1 of the present invention, the removal means for removing the asbestos surface and the sealing means comprising a plurality of wires closely planted in a portion in contact with the asbestos surface are provided. A sealing means made of a transparent material to cover, a gripping means that is fixed to a portion of the removal means that is not covered by the sealing means, and a part of which is configured as a handle that can be gripped by an operator, and one end of the sealing means Since it is composed of suction means consisting of a suction flexible tube that is airtightly connected to the suction port drilled in the other end and connected to the compressor at the other end, it is efficient with the least burden on the operator The asbestos surface can be peeled and removed well. Moreover, in the solution 1 , asbestos is removed not as a large lump but as a powder, so that the asbestos powder is always sucked in the best condition without imposing an excessive burden on the suction flexible tube and the compressor. Yes.

  Further, since the sealing means is composed of a plurality of wire rods, it is ensured that air appropriately flows in between the plurality of densely planted wire rods when the inside of the sealing means is decompressed by suction by a compressor. As a result, an airflow is always generated from the outside toward the inside of the sealing means, and the asbestos powder that has been peeled and crushed is pushed back into the sealing means by this airflow and does not leak to the outside. Furthermore, even if the removal target surface (asbestos surface) has irregularities and curves, the entire sealing means is well adapted to the irregularities and the curved surface due to the flexibility of each wire, so that no gaps are generated. In addition, when the operator presses the entire removal tool against the surface to be removed, the sealing means composed of a plurality of wire rods bends and acts as a cushion, thereby bringing about an effect that the work becomes extremely easy.

Further, since the sealing means that covers the entire action part of the removing means is made of a transparent material, the operator can remove the action part that peels and pulverizes the asbestos surface (the solution means 1 is a small disk for polishing). ) Is always visible. As a result, work can be performed while immediately responding to changes in the thickness of the asbestos surface, subtle irregularities, and surfaces made of other materials, etc. It became possible to do in. The operator can repeat the peeling and crushing operation many times until the residual asbestos is removed cleanly on the portion where the asbestos surface remains while visually recognizing the action portion. This is an effect peculiar to the present invention in which the operator holds the hand and the sealing means is made of a transparent material, for example, an effect that can never be achieved by a removal tool or the like by remote control.

According to the invention of Solution 1 of the present invention, since the removing means is a grinder having a rotating disk for polishing as an action portion, the asbestos surface is pulverized and removed. As a result, the load on the suction means is extremely small, and the capacity of the suction means can be reduced. In addition, large peeling pieces are not clogged inside the suction means, and the peeled pieces and powder that are made viscous as in the case of using a drug do not interfere with the suction ability of the suction means. In addition, since the working part is a rotating disc for polishing, it is possible to handle any thickness of asbestos surface by inserting the rotating disc deeply into the thick asbestos surface and shallowly turning the rotating disc into the thin asbestos surface. It is. Furthermore, the roughness of the grindstone of the rotating disk can be changed in various ways in which the hardness of the asbestos surface has changed, the asbestos surface is covered with something, or there is another surface under the asbestos surface. It is possible to cope with this by just

  Further, by using a small household grinder as the grinder for the removal means, the entire removal tool can be designed to be extremely light and compact. Therefore, even if the worker holds the hand for a long time, the work can be proceeded with a minimum feeling of fatigue. Further, even in a site where the action part must be held upward like a ceiling, the lightweight and compact configuration has a great effect on ease of work and reduction of fatigue. In addition, since a 100 V AC power supply that is standard equipment in any building can be used, no special power supply equipment is required for the work. Furthermore, for small grinders for home use, various types of grindstones are prepared as rotating discs for polishing and can be easily replaced, so it is possible to respond immediately to various aspects of asbestos surfaces. is there.

According to the invention of Solution 1 of the present invention, a wire that is a sealing means is densely planted adjacent to the first sealing means in which a plurality of rigid and flexible wires are densely planted, and the first sealing means. Since the second sealing means is composed of a plurality of wires that are slightly thinner than the wires of the first sealing means and slightly longer than the wires of the first sealing means, it consists of only a plurality of wires having a single thickness and length. The effect which is not in the sealing means can be produced. That is, the first sealing means composed of a plurality of slightly thicker and shorter wires is mainly responsible for maintaining a certain degree of sealing performance and rigidity of the entire sealing means, so that the operator can apply force only to one end of the asbestos removal tool. Even if it passes, it has a repulsive action, and an excessive inclination of the asbestos removal tool as a whole is prevented. Also, if the operator excessively presses the entire asbestos removal tool against the asbestos surface, the rigidity of the first sealing means stops the entire asbestos removal tool at a fixed position, and as a result, the removal means removes the asbestos layer. A malfunction that penetrates and scrapes down to the surface of the housing is prevented. On the other hand, the second sealing means composed of a plurality of slightly longer and thinner wires is mainly responsible for flexibility and high-level sealing performance, and at the same time increases the sealing performance that is insufficient with only the first sealing means, and at the same time, cushioning action This reduces the reaction felt by the operator, so that the feeling of work becomes very good. This point is extremely important because the present invention is a work that is held by a worker for a long time.

Next, according to the invention of the solution means 1 of the present invention, the illumination means that can illuminate the vicinity of the rotating disk for polishing of the action part of the removing means is attached to the gripping means or the sealing means. Regardless of the situation, the operator can continue the work while always paying attention to the situation in which the polishing rotating disk is cutting the asbestos surface. As mentioned above, there are places where it is difficult to reach the lighting at the work site depending on the work site. However, if the lighting device can always clearly grasp the cutting status of the rotating disk, the worker can efficiently use it without waste. You can proceed to work.

Next, according to the invention of the solution means 2 of the present invention, when the axial direction of the rotating shaft of the rotary disk for polishing of the action part of the removing means is the vertical direction, the front end portion of the sealing means made of a transparent material is Since it is configured at an angle of 90 ° or less in a plan view, the entire sealing means has a substantially right triangle shape in a plan view, and abuts extremely appropriately on the corner portion of the asbestos surface that is the removal target surface. In the configuration of the present invention, it is important to bring the rotating disk of the grinder, which is the removing means, as close as possible to the two sides constituting the corner portion at the corner portion of the surface to be removed. This can be achieved by making it a substantially right triangle. In addition, it becomes possible to cope with the case where the corner portion of the asbestos surface is slightly below 90 ° by configuring the tip portion of the sealing means at an angle of 90 ° to 80 ° in plan view. Further, it is possible to cope with a site where the corner portion of the asbestos surface is acute when the minimum value of the angle of the tip portion of the sealing means is about 30 °.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

<Configuration of Example 1>
As shown in FIGS. 1 to 5, the asbestos removal tool 1 according to the first embodiment includes a removing unit 2 that simultaneously peels and pulverizes the asbestos surface AS, and a plurality of wires that are densely planted in a portion in contact with the asbestos surface AS. And a sealing means 3 made of a transparent material that covers the entirety of the action part 21 of the removing means 2 and a part fixed to a portion of the removing means 2 that is not covered by the sealing means 3. (Not shown) gripping means 4 configured as a handle 41 that can be gripped by a hand, one end is hermetically connected to suction ports H1 and H2 drilled in the sealing means 3, and the other end is a compressor (see FIG. The suction means 5 is composed of the suction flexible tubes 51, 52, 53 connected to (not shown).

  The removing means 2 is a small grinder G composed of an action part 21 and a handle part 22. A motor (not shown) is built in the handle part 22, and a shaft 21 b is suspended from the action part 21 by the driving force of the motor. To rotate the polishing rotating disk 21a screwed in a horizontal state to the lower end of the shaft 21b. The grinder G is a small grinder for home use that is usually marketed in retail stores, and its configuration is a well-known technique, and thus detailed description thereof is omitted. The rotating disk 21a can be easily attached to and detached from the shaft 21b, so that the operator can easily replace the rotating disk 21a with another appropriate rotating disk according to the state of the asbestos surface AS. Note that SW is a power switch of the grinder G, and the sealing means 3 is configured not to cover the power switch SW.

  The sealing means 3 hermetically seals the entire action part 21 of the removing means 2 at least so as not to leak asbestos powder. The sealing means 31 made of a transparent material and the asbestos surface AS of the shielding body 31 are sealed. It is comprised from the sealing means 32 which consists of several wire rods densely planted in the part which contact | connects. Among these, the cover 31 has a triangular shape that protrudes downward in plan view as is apparent from FIGS. 2 and 7, and the tip 31 a is configured to be 90 °. In the first embodiment, the angle of the tip portion 31a is 90 °. However, in an actual site, it is considered that there may be a case where the angle of the corner portion of the asbestos surface AS is slightly narrower than 90 °. An angle between degrees will be appropriate. If the angle of the tip 31a is too small, the rotating disk 21a is far from the corner portion of the asbestos surface AS, and therefore, the 80 ° position is considered to be the minimum value. The left side surface 31b and the right side surface 31c of the cover 31 are gently curved, and the back surface 31d is flat. The upper surface 31e has a dome shape, and a lower portion of a tip portion 42 of the gripping means 4 described later is fitted and fixed in the upper surface 31e. The tip portion 31a, the left side surface 31b, the right side surface 31c, the back surface 31d, and the top surface 31e, except for the right-angled portion of the tip portion 31a, are continuously formed as a single piece by being curved. Further, although the lower surface of the covering 31 is in an open state, a continuous flange F is integrally formed on the lower end portion of the tip portion 31a, the left side surface 31b, the right side surface 31c, and the back surface 31d so as to be inward. On the lower surface of F, sealing means 32 made of a plurality of wires W1, W2 (see FIG. 14a) is implanted. A transparent synthetic resin is used as the material of the cover 31, but an opaque material can be used for the flange F. The flange F is integrally fixed to the lower end portions of the tip portion 31a, the left side surface 31b, the right side surface 31c, and the back surface 31d. Further, as shown in FIGS. 3 and 10, the flange F fixed to the lower end portion of the back surface 31 d has a shape in which the central portion swells rearward. This is to prevent the rotating disk 21a from colliding with this portion.

  As shown in FIG. 9, circular suction ports H <b> 1 and H <b> 2 and a substantially square mounting hole HG are formed in the back surface 31 d of the cover 31. Although the suction ports H1 and H2 are the same size, the suction port H1 is drilled on the left side of the back surface 31d and the suction port H2 is drilled on the right side of the back surface 31d, but the suction port H1 has a flange HF1 projecting rearward. Is provided integrally with the back surface 31d, and a flange HF2 protruding rearward is provided integrally with the back surface 31d at the suction port H2. Further, since the mounting hole HG is a structure for inserting the handle 22 of the grinder G of the removing means 2, the mounting hole HG has the same shape as the cross-sectional shape perpendicular to the longitudinal direction of the handle 22 of the grinder G. In the asbestos removal tool 1 of Example 1, the cross-sectional shape perpendicular to the longitudinal direction of the handle 22 of the grinder G is a substantially square shape with each side slightly bulging outward, so the mounting hole HG has the same shape. It is configured.

  A packing P for stably inserting the handle portion 22 of the grinder G is fitted to the peripheral edge portion HGr (see FIG. 10) of the mounting hole HG. The structure of the packing P is as shown in FIG. 11, and a concave portion Pc is formed in the outer peripheral portion Pa. As shown in FIG. 10, the peripheral portion HGr of the mounting hole HG of the back surface 31d is fitted in the concave portion Pc. As a result, the packing P is fixed to the peripheral edge portion HGr of the mounting hole HG. The inner peripheral portion Pb of the packing P has the same shape as the cross-sectional shape perpendicular to the longitudinal direction of the handle portion 22 of the grinder G, and is slightly smaller than the cross-sectional shape. Therefore, the handle portion 22 is inserted into the packing P. Then, the handle 22 is fixed to the back surface 31d via the packing P by the elastic force and repulsive force of the packing P. That is, the entire grinder G is fixed to the cover 31 of the sealing means 3.

The sealing means 32b is configured. That is, the first sealing means 32a and the second sealing means 32b are adjacent to each other. Further, when the wire W1 constituting the first sealing means 32a and the wire W2 constituting the second sealing means 32b are compared, the wire W2 is slightly thinner in diameter but slightly longer than the wire W1. The diameter of the wire W2 is considered to be 50 to 80% of the diameter of the wire W1, and the length of the wire W2 is considered to be about 105 to 125% of the length of the wire W1. Further, when comparing the planting densities of the first seal means 32a and the second seal means 32b, the planting density of the second seal means 32b is higher. 15a to 15c show different arrangement methods of the first sealing means 32a and the second sealing means 32b.

  Next, the configuration of the gripping means 4 will be described. As shown in FIGS. 1 to 9, the gripping means 4 includes a handle 41 from the center to the rear, a tip 42 connected to the front of the handle 41, and a holder connected to the lower rear end of the handle 41. 43, the handle 41, the tip portion 42, and the holder portion 43 are all formed as one body, and in particular, the handle 41 and the tip portion 42 are formed as one continuous member that is visually continuous.

The tip portion 42 which is connected to the handle 41 and is hollow inside is fitted and fixed at the lower portion inside the upper surface 31e of the covering 31 of the sealing means 3, and the action portion 21 of the removing means 2 is polished at the most distal portion. The illumination device 42a is mounted at an angle so that the vicinity of the rotary disk 21a can be illuminated. Reference numeral 42b denotes a switch of the lighting device 42a, which is attached to the upper surface of the tip portion 42, and 42c denotes a switch box attached to the inside of the tip portion 42. The cord C2 connecting the lighting device 42a and the switch box 42c enters the switch box 42c, and further, from the rear end of the switch box 42c, becomes a power cord C3 and passes through the cavity inside the tip portion 42 and the handle 41, and the handle 41 It is led out from the rear end. In addition, although the method of adhering the front end portion 42 and the covering body 31 is adhesion in the asbestos removal tool 1 of the first embodiment, the front end portion 42 and the covering body 31 are firmly attached by screwing or welding. Any method can be used as long as it can be fixed.

  As shown in FIGS. 1 to 9, 13 a, and 13 b, the holder portion 43 includes a pipe holder portion 43 a that is an upper portion and a grinder holder portion 43 b that is a lower portion. The pipe holder portion 43a is a substantially cubic member formed integrally with the rear end portion directly below the rear end portion of the handle 41. The pipe holder portion 43a is made of a hard resin, and has a circular hole H5 on the back surface and a circular shape on the left side surface. A hole H3 and a circular hole H4 are formed on the right side. The circular holes H3, H4, and H5 communicate with each other inside the pipe holder portion 43a. As seen in the cross-sectional view of the pipe holder portion 43a in FIG. Yes. Further, a flange HF3 protrudes rearward around the circular hole H3, a flange HF4 protrudes leftward around the circular hole H4, and a flange HF5 protrudes rightward around the circular hole H5.

Since the grinder holder portion 43b is a member for fixing the handle portion 22 of the grinder G as seen in FIGS. 1 to 9, the pipe holder as shown in FIGS. 5, 9, 13a and 13b. The left belt LB extends integrally from the lower left side of the portion 43a and the right belt RB extends integrally from the lower right side of the pipe holder portion 43a. The lower end of the left belt LB and the lower end of the right belt RB are A space S (see FIGS. 13a and 13b) composed of the left belt LB and the right belt RB comes into contact with the lower portion and becomes a fastening portion U. The shape is equal to the cross-sectional shape perpendicular to the longitudinal direction of the handle portion 22 of the grinder G. I am doing. A rubber lining GS is integrally attached to the inner side LB1 of the left belt LB, the inner side RB1 of the right belt RB, and the lower surface 43c of the pipe holder portion 43a. Since it is crimped | bonded to the surface of the handle | grip part 22 of the grinder G inserted and fitted in, the handle | grip part 22 of the grinder G can be stably fixed to the grinder holder part 43b. The handle 22 is fixed by finally firmly fastening the four bolts and nuts BN of the fastening part U and fixing the lower end of the left band LB and the lower end of the right band RB together. It is.

Next, the suction means 5 that sucks the asbestos powder inside the sealing means 3 will be described in detail. As shown in FIGS. 1 to 5, the suction means 5 includes three suction flexible tubes 51, 52, and 53 made of a film-like synthetic resin. As shown in FIGS. 2 and 3, one end of the suction flexible tube 51 is hermetically connected to the suction port H <b> 1 formed in the back surface of the covering 31 of the sealing means 3, and the other end is the holder portion 43. The pipe holder portion 43a is airtightly connected to a circular hole H3 formed in the left side surface. That is, since the inner peripheral surface of the suction flexible tube 51 is slightly smaller in size than the outer peripheral surface of the flange HF1 of the suction port H1, it fits into the flange HF1 while enlarging one end of the suction flexible tube 51. However, in order to ensure further airtightness and stable fixing, the connecting portion is tightened by the fastening ring R1. The fastening ring R1 is an annular member whose one end is fastened by a bolt nut BN. Similarly, the other end of the suction flexible tube 51 is hermetically connected to the flange HF3 of the circular hole H3 of the pipe holder portion 43a, and the connecting portion is further connected by a fastening ring R3 having the same configuration as the fastening ring R1. Tightened.

As shown in FIGS. 2 and 3, one end of the suction flexible tube 52 is hermetically connected to the suction port H <b> 2 formed in the back surface of the cover 31 of the sealing means 3, and the other end is the holder portion 43. The pipe holder portion 43a is hermetically connected to a circular hole H4 formed in the right side surface. That is, since the inner peripheral surface of the suction flexible tube 52 is slightly smaller in size than the outer peripheral surface of the flange HF2 of the suction port H2, it fits into the flange HF2 while enlarging one end of the suction flexible tube 52. However, in order to ensure further hermeticity and stable fixation, the connecting portion is tightened by the fastening ring R2 having the same configuration as the fastening ring R1. Similarly, the other end of the suction flexible tube 52 is hermetically connected to the flange HF4 of the circular hole H4 of the pipe holder portion 43a, and the connecting portion is further connected by a fastening ring R4 having the same configuration as the fastening ring R1. Tightened. In the asbestos removal tool 1 according to the first embodiment, the suction flexible tubes 51 and 52 have the same size and are arranged substantially symmetrically. Further, the suction flexible tube 53 has the same size. The configuration of the suction flexible tubes 51, 52, and 53 is the same as that of a flexible tube (known technique) used as a suction hose in various sites, and thus detailed description thereof is omitted. .

As shown in FIGS. 2 and 3, the suction flexible tube 53 is hermetically connected at one end to a circular hole H5 formed in the back surface of the pipe holder portion 43a of the holder portion 43, and the other end is not shown. Connected to the compressor. That is, since the inner peripheral surface of the suction flexible tube 53 is slightly smaller than the outer peripheral surface of the flange HF5 of the suction port H5, the suction flexible tube 53 is fitted to the flange HF5 while enlarging one end of the suction flexible tube 53. However, in order to ensure further airtightness and stable fixing, the connecting portion is tightened by the fastening ring R5. The fastening ring R5 has substantially the same configuration as the fastening ring R1, but is different in that a bulging portion R5a for binding the power cord C3 is provided on the upper part. As is clear from the above configuration, the suction flexible tubes 51, 52, 53 are in communication with each other through a communication hole H6 formed in the pipe holder portion 43a.

1 to 5, C1 is a power cord that extends from the rear end of the grinder G to a power source (not shown). C3 is a power cord that extends from a switch box 42c inside the distal end portion 42 of the gripping means 4 to a power source (not shown). The power cords C1 and C3 are fastened together with a suction flexible tube 53 by a fastening ring R6. The fastening ring R6 has substantially the same configuration as the fastening ring R1, but includes a bulging portion R6a for binding the power cord C3 at the upper portion and a bulging portion R6b for binding the power cord C1 at the lower portion. Is different. The power cords C1 and C3 and the suction flexible tube 53 are bundled by a plurality of fastening rings (not shown) having the same configuration as the fastening ring R6.

<Operation of Example 1>
The operation of the asbestos removal tool 1 of Example 1 will be described below with reference to the drawings. The asbestos removal tool 1 shown in FIGS. 1 to 5 is used by an operator (not shown) holding the handle 41 of the holding means 4 with one hand. At this time, when removing asbestos on the ceiling surface, the asbestos removal tool 1 is used in a form in which the state shown in FIG. When removing asbestos on the wall surface, the state shown in FIG. 1 is turned over by 90 °, and the rotating disk 21a is used in a state parallel to the wall surface. Moreover, when removing the asbestos of a floor surface, it uses in the state of FIG. In any use state, the end (not shown) of the suction flexible tube 53 is connected to a compressor (not shown), and the power cords C1 and C3 are used in a state of being connected to a power source (not shown). The suction action of the compressor is always on.

  When the rotating disk 21a of the action unit is appropriately brought into contact with the asbestos surface AS, the operator turns on the power switch SW of the grinder G. Then, the rotating disk 21a for polishing of the action part 21 starts to rotate. When the operator puts a force on the handle 41 and presses the entire asbestos removal tool 1 against the asbestos surface AS, the rotating disk 21a peels and pulverizes the asbestos surface AS. The inside of the cover 31 is scattered by the suction action of the suction flexible tubes 51, 52, and 53, so that asbestos powder is drilled on the back surface 31 d of the cover 31. Then, the air is sucked into the pipe holder 43a from the suction ports H1 and H2, and further sucked into the compressor (not shown) by the suction flexible tube 53 through the communication hole H6. At this time, the suction flexible tubes 51 and 52 are airtightly connected to the communication hole H6 between the shield 31 and the pipe holder portion 43a, and the suction flexible tube 53 is also airtightly connected to the pipe holder portion 43a. Since it is connected to the hole H6, the asbestos powder does not leak into the atmosphere.

  Further, on the lower surface of the covering 31, leakage of asbestos powder into the atmosphere is also prevented by the action of the sealing means 32. The sealing means 32 is composed of a plurality of wire rods W1 and W2 densely planted in a brush shape, but since the pressure reducing action is always working through the suction flexible tubes 51 and 52 inside the shield 31, External air must flow from the gaps between the plurality of wires W1 and W2 of the sealing means 32. Therefore, an air flow from the outside to the inside is always generated in the sealing means 32, and asbestos powder in the covering body 31 is pushed back toward the inside of the covering body 31 before the sealing means 32 by the action of this air flow. Therefore, leakage from the sealing means 32 to the outside is prevented. In addition, since the rotating disk 21a of the action part 21 finely pulverizes asbestos almost completely, the above-mentioned action in the sealing means 32 is almost completely performed. Moreover, in the asbestos removal tool 1 of Example 1, since the means for making asbestos viscous, such as a chemical solution, is not used, the asbestos powder is sucked into the suction flexible tubes 51 and 52 in a powder state. It is not possible for the asbestos that has become viscous to leak from the sealing means 32 as in the case of using.

  An operator (not shown) rotates the disc according to the state of the asbestos surface AS while monitoring the thickness and hardness of the asbestos surface AS or the mixing condition of other substance layers by visual observation and the reaction felt by the handle 41. The abutting (pressing) state of 21a to the asbestos surface AS is changed, and the work is proceeded by selecting a state where the asbestos surface AS can be powdered most appropriately. At this time, since the covering 31 is made of a transparent material, the operator can work while visually confirming the state in which the rotating disk 21a peels and pulverizes the asbestos surface AS. Thereby, the asbestos surface AS can be peeled and removed almost completely. That is, if the residual asbestos can be confirmed by visual observation, the asbestos surface AS can be peeled and removed evenly by repeatedly applying the rotating disk 21a to the portion. Furthermore, it is good if the working chamber is always sufficiently bright and the vicinity of the rotating disk 21a is sufficiently visible, but in many cases it is not. If the operator feels that the vicinity of the rotating disk 21a is too dark, the lighting device 42a is turned on and the vicinity of the rotating disk 21a is brightly illuminated by turning on the switch 42b on the upper surface of the tip 42 of the gripping means 4. Therefore, the accurate removal work can be continued. When the removal operation is stopped, the rotary disk 21a is stopped by turning off the power switch SW of the grinder G. Further, the rotating disk 21a can be replaced with another rotating disk (not shown) depending on the state of the asbestos surface AS. Since this replacement work can be performed in exactly the same manner as the replacement work for the rotating disk of a small household grinder, description thereof will be omitted.

  Further, when the worker makes various contact / press operations on the asbestos removal tool 1 against the asbestos surface AS, the sealing means 32 is densely planted with a plurality of rigid and flexible wire rods W1. Since the first sealing means 32a and the second sealing means 32b made of a plurality of wires W2 slightly narrower and slightly longer than the wire W1 of the first sealing means 32a densely planted adjacent to the first sealing means 32a are provided. (Refer to FIG. 14a to FIG. 15c), it is possible to achieve an effect that is not found in sealing means (not shown) composed of only a plurality of wires having a single thickness and length. That is, the first sealing means 32a composed of a plurality of slightly thicker and shorter wires W2 is mainly responsible for maintaining a certain degree of sealing performance and rigidity of the entire sealing means 32, so that an operator (not shown) can remove asbestos. Even if too much force is applied to only one end of the tool 1, it has a repulsive action, and an excessive inclination of the asbestos removing tool 1 as a whole is prevented. Further, even when the operator excessively presses the entire asbestos removal tool 1 against the asbestos surface AS, the entire asbestos removal tool 1 is stopped at a fixed position by the rigidity of the first sealing means 32a, and as a result, the action portion The malfunction that the rotating disk 21a of 21 penetrates the asbestos surface AS and cuts to the housing surface (not shown) is prevented. On the other hand, the second sealing means 32b made of a plurality of slightly longer and thinner wires W2 is mainly responsible for flexibility and advanced sealing performance, and at the same time improves the sealing performance that is insufficient only by the first sealing means 32a. The cushioning action reduces the reaction felt by the operator's hand, so that the work feeling is very good. This point is extremely important because the asbestos removal tool 1 is a work that is performed by an operator holding it for a long time.

  By working in the manner as described above, most of the asbestos surface AS used on the ceiling, wall and floor of the building can be peeled and removed in a substantially complete state, and the asbestos powder is in the atmosphere. It is properly sucked without splashing. Even after stripping and removing with the asbestos removal tool 1, a slight asbestos surface remains in the corner of the building, but since the tip of the covering 31 of the sealing means 3 is configured at a right angle, the amount of residual asbestos is very small. It becomes. This small amount of residual asbestos is peeled and removed by the operator's manual work, but the labor is minimal.

  As described above, the present invention provides an easy-to-use and efficient asbestos removal tool that immediately responds to the actual situation in the field, and reduces the risk and burden experienced by workers in the asbestos peeling and removal work. In addition, it has a remarkable effect. Further, the present invention can deal with not only asbestos but also various other material layers by simply replacing the rotating disk of the working part with an appropriate one. For example, for coated surfaces of mortar and concrete, a rotating disk made of a material that can be peeled off from each surface may be used. Further, by using a rotating disk made of an appropriate material for peeling off various paint surfaces, etc. Applicable. In any case, the material layer peeled and pulverized by the action part of the removing means is almost completely sucked and removed by the suction means, so that the peeled powder is prevented from being scattered in the atmosphere. It greatly contributes to ensuring safety and environmental protection.
