Description

  The present invention relates to a curing method for asbestos treatment and an apparatus therefor, and more specifically, in the treatment of asbestos on the wall surface around the route of an elevator, the cables and rails arranged in the route are cured with respect to the treatment liquid of asbestos. The present invention relates to a curing method and an apparatus therefor.

WO00 / 46139

In recent years, the treatment of asbestos harmful to human bodies, which has been applied to existing buildings, has become a problem.
In elevators installed in high-rise buildings such as buildings, the wall surrounding the elevator's elevator path is no exception, and the treatment liquid is sprayed and solidified on the wall where asbestos is applied. Processing is desired.

  The inventor of the present application considered spraying the processing liquid from the elevator board when solidifying the asbestos on the wall surface surrounding the elevator lifting / lowering path. In this way, if the elevator board is used, the processing liquid can be sequentially sprayed on the wall surface by its elevation, and there is no need to separately install a scaffold or the like.

First, the example of the elevator used as the object which implements this invention is demonstrated.
The elevator E includes a hoistway e1 provided in a building such as a building, a riding guide rails e3 and e3 disposed on a peripheral wall e2 surrounding the hoistway e1, and a riding guide rail e3. A riding rod e4 which is guided by e3 and moves up and down, and a lifting device e5 which lifts and lowers the riding rod e4.
The riding rod e4 includes a ceiling portion e41, a floor portion e42, and a side surface portion e43, and has a box shape that is a space in which the riding rod interior is closed with respect to the outside of the riding rod. An automatic door e44 that opens and closes when the user gets on and off is provided on the side surface portion e43 of the riding rod.

The lifting / lowering device e5 includes a counterweight e51, counterweight guide rails e52 and e52, a rope hitch e53 provided at the upper end of one riding guide rail e3, and the other one of the car frame guide rails.

One end of the rope e57 is fixed to the rope hitch e53, is wound around the hoisting machine e54 via the car sheave e56 of the rider, and then the other one is passed through the counterweight sheave e58 of the counterweight e51. It is fixed to the rope hitch e54. In such a configuration, the riding e4 is moved up and down by driving the hoisting machine e54.
However, the lifting device e is not limited to the above-described one, and may employ other known configurations.

As shown in FIG. 2, in the elevator lifting / lowering path, a long arrangement t extending along the lifting / lowering path such as the guide rail and the power cable is disposed.
When the peripheral wall e2 asbestos treatment is performed by injecting a treatment liquid that solidifies asbestos from the elevator board e4 toward the peripheral wall e2 surrounding the elevator lifting path, The present invention provides a method for preventing the treatment liquid of asbestos from being applied to the object t, that is, a method for curing the long arrangement object t. Hereinafter, the curing method will be described in detail.

Asbestos injection from the rider e4 is performed by an operator who wears a mask or hooded work clothes and protects the body from asbestos with a spray device (spray gun) on the upper surface of the rider e4 ceiling. It is possible to ride and inject the processing liquid directly toward the peripheral wall e2, but the injection device 1 is installed on the upper surface of the ceiling e41 of the ride e4 and the injection operation is performed from within the ride e4. Alternatively, an injection robot may be installed on the upper surface of the ride e4 to automatically perform injection.
A preferred example of the injection device 1 will be described in detail later.

In the curing method of asbestos treatment according to this embodiment, when spraying the above-described treatment liquid, as shown in FIG. 2, the upper surface of the ride e4 (upper surface of the ceiling portion e41) along the longitudinal direction of the elongated object t A hollow covering member 8 that can be extended upward is provided on the elevator board e4.
Specifically, as shown in FIG. 3A, the covering member 8 includes a hollow main body 80 of the covering member 8, and a notch portion cut out along the longitudinal direction of the covering member 8 from the upper end to the lower end of the main body 80. The one provided with 81 and closing means 82 is employed.
As shown in FIG. 3A, the main body 80 has an accordion-like shape that alternately includes a large diameter portion having a large outer diameter and a small diameter portion having a smaller outer diameter than the large diameter portion in the axial direction. . That is, the main body 80 of the covering member 8 includes a plurality of peaks in a side view. In other words, the main body 80 includes a plurality of constricted portions in the axial direction.
And as the said main body 80 of the coating | coated member 8, what shrink | contracts by receiving force in the direction compressed about a longitudinal direction while employ | adopting the attachment or removal with respect to the elongate arrangement | positioning t is employ | adopted. The main body 80 of the covering member 8 accommodates at least a portion to be cured in the longitudinal direction of the long object t.
Specifically, the length of the main body 80 is preferably set to 2.5 m to 5 m in the spraying of the asbestos solidifying agent using the above-described spray gun. However, such numerical values can be changed.
The main body 80 of the covering member 8 can be formed of plastic. In this embodiment, the covering member 8 employs a member that has elasticity to be shrunk by receiving a force in a compressing direction in the longitudinal direction and to recover by being released from such a force. In this embodiment, the main body 80 is formed in a bellows shape as shown in FIG.
As the main body 80 of the covering member 8, a self-supporting one is adopted, and the lower end is installed on the riding rod e4, so that it can be arranged on the upper surface of the riding rod e4. ), The covering member 8 includes a support member 83 serving as a support, which is separate from the main body 80 arranged on the riding rod e4. The main body 80 does not have self-supporting properties, and the support member 83 Even if the upper end of the main body 80 is attached to the upper end of the main body 80 and is suspended, it can be implemented. A magnet may be provided at the lower end of the support member 83 and the support member 83 may be installed on the upper surface of the ride e4.

  The covering member 8 can accommodate the long object t in the long object t through the notch 81, and the long arrangement that has been accommodated through the notch 81 after use. The fixture t can be taken out.

As shown in FIG. 3 (B), as the closing means 82, a thing that is provided in the main body 80 of the covering member 8 by the notch portion 81 and that locks both ends 8c and 8d in the circumferential direction r is used, and is arranged in a long shape. After the object t is accommodated, the end portions 8c and 8d in the circumferential direction r are joined.
As shown in FIGS. 3A and 3B, a wire fastener including an element 82a (service tooth) and a slider 82b (opening / closing component) can be used as the closing means. The element 82a is provided at the end portions 8c and 9d along the notch 81, and can be opened and closed by the slider 82b having a puller.
Moreover, a well-known surface fastener can also be employ | adopted for a fastener other than said general wire fastener.
In addition to the fastener, a magnet may be used for the closing means 82. In this case, a magnet is attached to one end of the circumferential direction r, and a metal or magnet attracted to the magnet is attached to the other end of the end.
Further, the closing means 82 can be a snap. In this case, one of a pair of male and female snaps is attached to one of the end portions in the circumferential direction r, and the other one of the male and female snaps is attached to the other one of the end portions.
When the elongate arrangement t to be cured is a guide rail, it is directly attached to the peripheral wall e3, or a support that supports the guide rail to the peripheral wall e3 at predetermined intervals in the vertical direction (like a railroad track) And a member corresponding to a sleeper). In such a case, both ends 8c and 8d of the covering member 8 main body 80 in the circumferential direction r are locked to each other and the notch 81 cannot be closed. In such a case, the cutout portion 81 is opened to cover the long object t, and the peripheral wall and the above support are removed by the open cutout portion 82 when the ride is lifted. That's fine. In this case, the covering member 8 does not require the closing means 82.

Moreover, since the injection of the processing liquid by the injection unit 3 is performed above the ceiling of the riding rod e4, that is, the injection port 51a is located at a higher position than the riding rod e4. The covering member 8 does not scatter on the side of the eaves e4, and the covering member 8 can reliably cure the long arrangement t. On the other hand, since the position of the injection port 51a of the injection unit 3 is lowered or the injection port 51a is injected downward, just in case, the cable t1 and the guide rail t2 are also provided on the side of the riding rod e4. If it is intended to cure the long object t, as shown in FIG. 2, a sub-cover member 9 is prepared, and a ride e4 of the long object t below the lower end of the cover member 8 is prepared. It is possible to cure the portion along the side surface.
The secondary covering member 9 is attached to the upper end of the main body 90 and has a semi-cylindrical shape obtained by vertically dividing the covering member 8 in the axial direction, and the main body 90 is detachably fixed to the rod e4. And a support member 84. In this embodiment, the main body 90 of the sub-coating member 9 is also formed in a bellows shape. As shown in FIG. 3C, the support member 84 has a C-shape in plan view. The support member 84 passes the elongated object 8 inside the C-shape (arc portion 84a). The support member 84 includes magnets 84b and 84b at both ends of the C-shape, and extends to the upper end of the side portion of the riding rod e4. Removably attached.
Thus, the main body 90 of the sub-cover member 9 is supported while being suspended from the support member 84, and covers a portion along the side of the ride e4 of the long object t.
Unlike the covering member 8, the sub-covering member 9 does not include a closing portion, and the end portion in the circumferential direction of the sub-covering member 9 is kept open.
And the coating | coated member 8 is arrange | positioned on the support material 84 installed in the side part upper end of the riding rod e4. In this case, instead of placing the covering member 8 directly on the upper surface of the riding board, the covering member 8 is placed on the support member 84.
However, the main body 90 of the sub-cover member 9 and the main body 80 of the cover member 8 may be fixed to the support member 84 from the beginning.
In addition, the auxiliary covering member 9 can be formed integrally with the covering member 8, and the arc portion 84a of the support member 84 can be turned and fastened to the valley portion of the bellows, that is, the constricted portion of the bellows.
However, in the case where the notch 81 is opened without providing a closing means for the covering member 8 in order to dodge the above-mentioned peripheral wall and the above-mentioned support for the guide rail, the sub-covering member described above is used. 9 cannot be provided.

As shown in FIGS. 4A to 4C, the elevator board e4 can sequentially drop the riding board e4 from the uppermost position of the lifting path to spray the processing liquid. As shown in FIG. 4A, at the uppermost position of the lifting path, the main body 80 of the covering member 8 is sandwiched between the ceiling portion e41 of the riding rod e4 and the ceiling (upper end wall e6) of the lifting path and contracts. It is in a state. In this state, the covering member 8 covers a portion of the long object t between the ceiling portion of the riding rod e4 and the ceiling of the lifting path. And as shown to FIG. 4 (B), the main body of the coating | coated member 8 is extended according to the fall of the riding rod e4. FIG. 4C shows a state in which the upper end of the main body 80 of the covering member 8 moves away from the ceiling of the lifting path and moves downward together with the ride e4 due to the lowering of the ride e4. Thus, by descending the riding rod e4, the solidified liquid can be sprayed on the surrounding wall surface sequentially from the upper side to the lower side, and the long arrangement object t can be cured by the above curing apparatus.
In FIG. 4, the solidified liquid can be sprayed while lowering the riding rod from the upper side to the lower side. On the contrary, the riding rod is raised to spread the solidifying liquid from the lower side to the upper side. It can also be done sequentially. In this case, even if the main body 80 of the covering member 8 is sandwiched between the ceiling of the route and the upper surface of the riding place due to the rising of the riding rod, the reverse operation, that is, the covering member 8 main body 80 is contracted. can do. That is, contrary to the above, the state shown in FIG. 4C is changed to the state shown in FIG. 4A through the state shown in FIG. 4B.
As described above, the length h1 of the main body 80 of the covering member 8 is 2.5 m to 5 m in a state where no compression force is applied, and in the most contracted state shown in FIG. The length h0 of the main body 80 may be reduced to the same distance as the distance between the riding rod and the ceiling of the route, and is usually preferably 1 m.
In the above, it is preferable that the treatment liquid is sprayed while observing the target surface by stopping every time the platform is lowered by 500 to 1000 mm. However, such a setting can be changed.
In addition, when using the support member 83 as shown to FIG. 3D, the thing which expands and contracts is employ | adopted as the said support member 83, and it shall be able to respond | correspond to the raising / lowering of said riding.

Another embodiment of this curing method will be described.
As shown in FIG. 5 (A), this curing method employs the body 80 of the covering member 8 constituted by a plurality of cylindrical bodies 80a, 80b, 80c.
The cylindrical bodies 80a, 80b, and 80c have different diameters, and the cylindrical bodies 80a, 80b, and 80c are overlapped. Each cylindrical body can be formed of plastic. In the state of being stacked in this way, the covering member 8 accommodates the elongated object t inside the cylindrical body 80a located on the innermost side.
In the above, by arranging the inner cylindrical body with respect to the outer cylindrical body or the outer cylindrical body with respect to the inner cylindrical body in a state of being drawn upward, the elongated arrangement t Cover at least the curing part.
In this embodiment, the main body 80 of the covering member 8 is composed of three cylindrical bodies. However, the number of cylindrical bodies is not limited to such a number, and is two. However, it can be carried out even with four or more.
Moreover, although each said cylindrical body is a cylindrical shape, even if it is a rectangular cylinder shape which has a polygonal cross section, it can implement.

As shown in FIG. 5B, each cylindrical body has a configuration in which the upper end is sealed by the upper surface portion 80d with the axial direction being the vertical direction, and the lower end is opened.
The upper surface portion 80d of the cylindrical body includes a through portion 80d penetrating vertically, and the cylindrical body accommodated therein can be exposed upward from the through portion 80d.
A hooking portion 80e is provided around the lower end of the cylindrical body so as to protrude outward in the radial direction of the cylindrical body from the outer peripheral surface of the cylindrical body. The hook portion comes into contact with the lower surface of the upper surface portion 80d of the other cylindrical body when it is pulled out of the other cylindrical body in the cylindrical body housed in the other cylindrical body, and is pulled upward. It is something to prevent. In this embodiment, the hook portion 80e is a hook-like portion formed on the outer periphery of the lower portion of the cylindrical body. However, the hooking portion 80e can be implemented as a protrusion that protrudes radially outward from the outer peripheral surface of the cylindrical body.

Each cylindrical body is provided with the notch 81 cut out along the axial direction of the cylindrical body from the upper end to the lower end of the cylindrical body, that is, the longitudinal direction of the covering member 8, and the closing means. ing. As the closing means, the above-described line fastener, surface fastener, snap, or one using a magnet described in the description of the embodiment shown in FIG.
In this embodiment, the closing means using the aforementioned magnet is employed.
Each cylindrical body can be deformed by being formed of elastic plastic. By such deformation, the cutout portion 81 is spread against the magnetic force of the magnet, so that the long arrangement is provided. Take t in and out.

In this embodiment, the cylindrical bodies 80a and 80b of the main body 80 are friction resistances between the penetrating portion 80f and the outer peripheral surfaces of the cylindrical bodies 80a and 80b in a state of being pulled out from the other cylindrical bodies 80b and 80c. Thus, the state drawn from the other cylindrical bodies 80b and 80c shown in FIGS. 5A and 5B is maintained.
In this embodiment, unlike the covering member 8 shown in FIG. 3A, after the main body 80 is contracted from the extended state, if the operator does not pull out again, the main body 80 may be in the extended state. Can not. For this reason, in the dispersion | spreading operation | work of a process liquid, it is necessary to move the riding rod e4 from the downward direction upwards. That is, before the work, when the body 80 of the covering member 8 is extended to the state shown in FIG. 5B and the ceiling (upper end wall e6) of the lifting path approaches due to the rising of the riding rod e4, the ceiling and The main body 80 contracts to the state shown in FIG. 5C by abutting and being pushed by the ceiling.
In the embodiment shown in FIG. 5 as well, configurations other than those specifically mentioned are the same as those of the other embodiments described above.

In the embodiment shown in FIG. 5, in order to prevent the processing liquid from splashing into the cylindrical body and entering the inside of the main body 80 from the through portion 80f of the cylindrical body, FIG. The main body 80 can be covered with a separate bag 85 shown in FIG.

Although not shown in the figure, the above-mentioned line fasteners, hook-and-loop fasteners, magnets or snaps are provided on a pair of opposite sides of the sheet, and both sides are fastened, and a sheet is used as a ring to form a bag. do it.
Further, such a bag body 85 can be used as a main body of the covering member 8, and a portion of the covering member 8 covered by the bag body 85 can be provided to support the bag body. In this case, the portion accommodated in the bag body 85 of the covering member 8 does not need to cover the long object t, and may be one having only a configuration that expands and contracts. For example, in the bag body 85, it can also be implemented with the elongated arrangement t located outside the member housed in the bag body 85 of the covering member 8, and in this case, each part of the member is a cylinder. There is no need to form it as a body.
For example, as shown in FIG. 6C, as the covering member 8, a bag body 8a that opens up and down, a top plate 8b that closes the upper opening of the bag body, and a base 8c that is installed on the upper surface of the ride e4, A thing provided with the top plate 8b and the expansion-contraction member 800 interposed between the top plate 8b and the base | substrate 8c is employable.
