Specifically, as shown in FIG. 2, the processing apparatus 1 injects the closing portion 2 detachably disposed on the upper surface of the ceiling portion e45 of the elevator board e4 and the asbestos processing liquid onto the wall surface. And an injection unit 3. The injection unit 3 corresponds to the injection device in the claims. The closing part 2 corresponds to the closing member of claim 1 and the closing part of claims other than claim 1.
The closing part 2 closes or covers the existing opening e45 on the ceiling of the ride. In this embodiment, the closing part 2 supports the injection part 3.

The closing part 2 includes a closing body 20 and a placement part 21.
The closed body 20 has a contour shape similar to the contour shape of the opening e45 of the ride e4 in plan view, and can be inserted into the opening e45 to close the opening e45.
Specifically, in this embodiment, the closing body 20 is formed in a hollow box shape with a foam material having a strength capable of supporting a periscope unit to be described later, for example, an opening e45. Is opened in a circular shape, the closing body 20 is formed as a cylindrical hollow body, and is formed in a polygonal column shape when the shape of the opening e45 is a polygon. Therefore, when the opening e45 is rectangular in plan view, the shape of the closing body 20 in plan view is also set to be rectangular.
The closing body 20 includes a through hole 22 to which a later-described periscope unit is attached.
The through-hole 22 penetrates the closing body 20 up and down. The through-hole 22 has a circular outline in plan view.

In this embodiment, bearing portions 4 and 4 are provided at the upper end opening and the lower end opening of the through-hole 22, respectively. However, the number and arrangement of the bearing portions 4 are not limited to the above and can be changed.

  The closing body 20 includes an exposed portion that is exposed upward from the outer upper surface of the ceiling portion e41 of the riding rod e4, and the placement portion 21 is a protruding portion that extends laterally from the exposed portion. In this embodiment, the mounting portion 21 is a bowl-shaped body formed integrally with the closing body 20 by the hard foam material that constitutes the closing body 20. However, the present invention can also be implemented by forming the mounting portion 21 separately from the closed body 20 and fixing it to the closed body 20. Moreover, said saddle-like body may be provided with the site | part notched about the circumferential direction. Furthermore, the mounting portion 21 can be formed as a plurality of protrusions instead of being formed in a bowl shape.

The body 20 is supported. Therefore, the mounting portion 21 is not limited to the above-described saddle-like body, and can be formed as a plurality of protrusions provided on the opposite side across the opening e45 as described above. By forming such a protrusion so as to protrude from the side surface of the exposed portion of the closing body 21 and adopting the above arrangement, the closing body 20 can be supported in the same manner as the hook-shaped portion.
In the above, the lower surface of the mounting portion 21 is a contact portion that contacts the ceiling portion e41 of the ride.

  In the above, both the mounting portion 21 and the closing body 20 are preferably formed of a material having cushioning properties in terms of airtightness, and as described above, formed of a hard foam material. preferable. For example, urethane foam can be used for the placement portion 21 and the closing body 20. In addition, the mounting part 21 and the closing body 20 can be implemented even if they are formed of metal such as iron or aluminum, wood, or plastic. In this case, as shown in FIG. 3C, it is preferable that the sheet 21a made of a foam material is separately provided on the lower surface of the mounting portion 21 as a contact portion. Further, as shown in FIG. 3C, if the sheet 21a is disposed so as to be hung on the side of the closing body 20, the sealing performance of the opening e45 can be further improved.

As shown in FIG. 2, the injection unit 3 includes a periscope unit 30, an injection device 5, a liquid tank 6 that is a processing liquid storage unit that solidifies asbestos, and an air tank 7 that stores compressed air (air). . Both tanks 6 and 7 are arranged in the riding rod e4.

However, the number of each crosspiece 23 is not limited to the above. Moreover, although the same number may be sufficient as the 1st crosspiece 23a and the 2nd crosspiece 23b, it can implement even if it is a different number.
In this embodiment, the first crosspiece 23a and the second crosspiece 23b intersect at a right angle, but the present invention can be implemented even at other angles.

The placing portion 21 is placed on the sheet-like body including the closing portion 20 on the outer upper surface of the riding rod e4.
When the direction in which the first bars 23a, 23a extend is the front-rear direction and the direction in which the second bars 23b, 23b extend is the left-right direction, the length of the first bars 23a, 23a is It is larger than the width, and the length of the second bars 23b, 23b is larger than the left and right widths of the sheet-like body.
Both ends of each crosspiece 23 are provided with grounding portions 23e that protrude downward from other portions of the crosspiece 23. In this embodiment, the lower end surface of the ground contact portion 23e is the abutting portion, and abuts against the outer upper surface of the riding rod e4 as shown in FIG.

It is preferable that the length of each bar 23 can be adjusted according to the size of the opening.
In other words, for each crosspiece 23, one that can be expanded and contracted is employed. Specifically, as shown in FIG. 5C, which is a cc end view of FIG. 5B, each crosspiece 23 is accommodated in a hollow first bar 23c and the first bar 23c. And separate second bars 23d and 23d. Then, the crosspiece 23 can be extended by pulling out the second bar members 23d and 23d from both ends of the first bar member 23c, and conversely, the second bar members 23d and 23d are pushed into the first bar member 23c. Thus, the crosspiece 23 can be shortened. As shown in FIG. 5C, a C-type channel material can be employed as the first bar 23c.
The grounding portions 23e and 23e are provided at the tips of the exposed portions of the second bar members 23d and 23d. As shown in FIG. 5D, the downward projecting width w2 of the ground contact portion 23e is set so that there is no gap between the contact portion and the upper surface of the ride e4. Specifically, the grounding portion 23e is formed so that the width obtained by adding the thickness w1 of the sheet-like body and the thickness of the hollow first bar 23c is equal to the protruding width w2.

The covering 20 formed by the sheet-like body is provided with a through-hole 22 that penetrates vertically (front and back). Above the through-hole 22, a central portion 23 f of the cross beam presented by the crosspieces 23, 23, that is, a space surrounded by the cross beam is arranged. The periscope unit 30 is passed through the through hole 22 and the central portion 23f.

Using the above apparatus, an operator rides on the elevator rod e4 and turns the wall-surface periscope portion 30 while looking through the observation port of the periscope portion 30 from the inside of the ride rod e4 to operate the spray gun. As a result, the asbestos treatment liquid can be sprayed onto the wall surface around the lifting path.
During the operation, the vertical position of spraying can be changed by raising and lowering the elevator board.
Since the opening e45 that is already installed in the ride is closed by the above-described closing portion, the worker can proceed with work safely from asbestos.

In the embodiment shown in FIGS. 1 to 5, the closing portion 2 supports the injection portion 3, but the closing portion 2 supports the injection portion 3 only by closing the opening e <b> 45. Even if not, it can be implemented. For example, the closing part 2 is made of only cloth or other sheet-like body, and the closing part 3 is provided with a hole for projecting the injection port of the injection part 3 to the outside of the ride, It can also be implemented as a case where the worker has the injection unit 3 and inserts the injection port side into the hole and protrudes outside the riding board to perform the processing operation.
Moreover, in the above, the injection part 3 integrated the periscope part 30 and the injection apparatus 5, but the periscope part 30 and the injection apparatus 5 are separately attached to the closing part 2. Can also be implemented. However, by attaching the injection device 5 to the periscope unit 30, the direction of the injection port can be changed by the turning operation of the periscope unit 30, and the operation is easy to perform.
In the embodiments shown in FIGS. 5B to 5D, matters other than the matters specifically mentioned are the same as those in the embodiments shown in FIGS. Any one of those shown in FIG. 2 and those shown in FIG. 5A can be used).
In each of the embodiments described above, instead of the periscope unit described above, a TV camera is installed on the outside of the ride e4, that is, on the top surface of the ride e4, and a monitor is installed in the ride as a visual recognition means. Further, the present invention can be carried out as spraying of a processing liquid and observing a wall surface. In this case, the camera may be provided with the anti-fogging means.
Furthermore, in the processing method shown in FIGS. 1 to 5, the injection device is provided at one place, but it can also be implemented by providing two or more injection devices at different positions on the ride e4. . In other words, the present invention can be carried out by arranging a plurality of injection devices within a range that can be accommodated in an existing opening.

During the above operation, the asbestos treatment liquid is prevented from being applied to the elongated object t extending along the lifting path, such as a power cable or a guide rail, which is disposed in the lifting path of the elevator, that is, The long arrangement t is preferably cured.
Hereinafter, such a curing method will be described.

As shown in FIG. 6, this asbestos curing method is a hollow covering member 8 that can be extended upward from the upper surface of the ride e4 (upper surface of the ceiling portion e41) along the longitudinal direction of the elongated object t. Is provided on the elevator board e4.
Specifically, as shown in FIG. 7A, 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 the main body 80 of the covering member 8, a body that can be attached to and detached from the long object t and contracts by receiving a force in a compressing direction in the longitudinal direction is 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 e 4 so that it can be arranged on the upper surface of the riding rod e 4. ), 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. 7 (B), as the closing means 82, a thing which is provided in the main body 80 of the covering member 8 by the notch portion 81 and which 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. 7A and 7B, 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 the long object t is to be cured, as shown in FIG. 6, a sub-cover member 9 is prepared, and the elongate object t 4 elongates from the lower end of the cover member 8. 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. 7C, 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 is turned and fastened to the bellows valley portion.
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. 8 (A) to 8 (C), 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. 8A, 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. 8 (B), the main body of the coating | coated member 8 is extended according to the fall of the riding rod e4. FIG. 8C shows a state in which the upper end of the main body 80 of the covering member 8 is separated from the ceiling of the lifting path and moved 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. 8, 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. 8C is changed to the state shown in FIG. 8A through the state shown in FIG. 8B.
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 compressive 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 supporting member 83 as shown in FIG.7 (D), the thing which expands and contracts is employ | adopted as the said supporting member 83, and it shall be able to respond to the raising / lowering of said riding board.

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. 9B, each cylindrical body has a configuration in which the upper end is sealed by the upper surface portion 80d and the lower end is opened with the axial direction as the vertical direction.
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 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. 9A and 9B is maintained.
In this embodiment, unlike the covering member 8 shown in FIG. 7A, 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. 9B 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 is brought into contact with and pressed against the ceiling so that the main body 80 contracts to the state shown in FIG.
Also in the embodiment shown in FIG. 9, the configurations other than those specifically mentioned are the same as those of the other embodiments described above.

Furthermore, 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 80. 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.

Still another embodiment will be described.
In the embodiment shown in FIG. 9 and FIG. 10 (A), each cylindrical body constituting the main body 80 of the covering member 8 includes a notch 81, and the long object t is provided from the notch 81. It was supposed to put in and out. In addition, as shown in FIG. 10 (B), each cylindrical body constituting the main body 80 of the covering member 8 has a plurality of shapes formed by dividing the cylindrical body in the circumferential direction r of the cylindrical body. It is possible to employ a member that includes a cylinder constituent member and a closing portion that combines the cylinder constituent members and fixes them as one cylindrical body.
In the embodiment shown in FIG. 10B, each cylindrical body is composed of two semi-cylindrical cylinder constituent members 80x and 80y obtained by vertically dividing the cylinder in the axial direction. However, the cylindrical component member is not limited to the one in which the cylinder is divided into two in this way, that is, two cylindrical component members that constitute the cylindrical body, but three or more cylindrical component members It can also be implemented as a single cylindrical body.
As the closing portion, as in the embodiment shown in FIG. 9, those that can be adopted in the embodiment of FIG. 7A can be adopted. In the embodiment shown in FIG. A thing using a magnet is employable as a closure part.
