The present invention relates to a lining material inverting apparatus which inverts and inserts a tubular pipe lining material for repairing the line by lining the inner surface of an aging line.

When pipelines such as sewage pipes, gas pipes, communication cable pipes, and power cable pipes buried in the ground become obsolete, a pipe lining method is proposed to repair the pipelines by lining the inner surfaces of the pipelines without digging them from the ground. It is already provided for practical use.

As one of the tube lining methods, it is known that the outer surface is constructed by using a tube lining material formed by impregnating a non-cured liquid thermosetting resin into a tubular resin adsorbent coated with a plastic film in an airtight manner. The thermosetting resin impregnated in the tube lining material in the state in which the tube lining material is inverted and inserted into the pipeline by the fluid pressure, and the upper engine lining material is expanded by the fluid pressure and compressed onto the inner surface of the pipeline using a lining material inverting device. Is thermosetting.

Usually, the tube lining material is housed in a storage container in a flat and folded state, and one end of the tube lining material stored in the storage container is folded outward and attached to the outer end circumference of the inverted nozzle connected to the storage container for storage. The fluid pressure is applied to the vessel and inverted into the pipeline while inverting (Patent Document 1).

In addition, the tube lining material is wound in a reel on a roll and stored in a storage container.

In such a conventional lining material inverting apparatus, after the tube lining material is inverted and inserted into the pipeline, in order to thermoset the thermosetting resin impregnated in the tube lining material, the inverting nozzle is cut out from the inverting device body, and the inverting nozzle is covered with a cover. A supply hose for supplying fruit such as hot water and steam is introduced into the inside of the tube lining material from the top of the inversion nozzle.

However, the operation of introducing the hose from the top of the inverted nozzle to the inside is not easy, and when the hose is introduced from the top, it is difficult to observe the hose introduction state, so that the hose is often not well introduced into the tube lining material. In the state, there existed a problem that the thermosetting of the inverted tube lining material started. In addition, when introducing not only the fruit supply hose but also the discharge hose for discharging the fruit used for thermosetting into the tube lining material, the drainage hose is not well introduced into the tube lining material, and the fruit is insufficiently discharged. There was also a problem that it was difficult to circulate and use the fruit.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a lining material inverting device capable of satisfactorily introducing a hose for supplying or discharging a fruit for thermosetting the tube lining material into the inverted tube lining material. do.

The four corners of the storage container 20 are provided with top and bottom adjustment mechanisms 13 and 14 (two of which are not shown since the remaining two are not shown), whereby the storage container 20 can be kept horizontal. have.

As shown in FIG. 2, the receptacle nozzle 30 is detachably attached to the storage container 20 via a conduit 22 having a plurality of guide rollers 21 and an attachment tube 60. The inversion nozzle 30 consists of the nozzle part 30a which the cylindrical front end (lower end) opened, and the cone part 30b which is airtightly attached to the nozzle part 30a, and this cone part 30b has One end of the attachment pipe 60 is likewise hermetically attached. As will be described later, the attachment pipe 60 has an air supply hose, an air discharge hose, a fruit supply hose, its discharge hose, and the like from the side after the reversal insertion of the pipe lining material 1 into the pipeline is completed. It has a structure that can be introduced, and before each hose is attached, the hose fitting port is sealed and has an overall sealed structure.

A conduit 22 is hermetically attached to the attachment pipe 60, and a flange 22a is fixed to an end opposite to the attachment pipe 60 of the conduit 22. The flange 22a and the flange 23a attached to the side pipe 23 extending laterally of the storage container 20 are capable of being hermetically connected to each other through fixing means such as a plurality of bolts and nuts. When the inversion nozzle 30, the attachment pipe 60, the conduit 22, and the storage container 20 are coupled to each other, the entirety of the inversion nozzle 30 is open except that the front end (lower end) of the inversion nozzle 30 is opened. It is a sealed structure.

In addition, bearing portions 25 are attached to both sides of the storage container 20 to axially support the reels 24. The reel 24 is used to wind the tube lining material 1 in a roll shape, and is driven by an electric motor (not shown) to rotate clockwise in FIG. 2, whereby the tube lining material 1 is provided. Is wound on a reel 24 in roll form. Moreover, the wheel 24b provided with the some spoke 24a is affixed on both sides of the reel 24, and the winding of the pipe lining material 1 is assured by this.

In addition, when the tube lining material 1 wound around the reel 24 is pulled out of the storage container 20 and reversed as described later, the reel 24 is reversed by a torque acting on the reel 24. It rotates, rotates an electric motor, operates it as a generator, and braking is performed by drawing out a tube lining material.

In addition, the storage container 20 is provided with a duct 26 for sending a fluid pressure (compressed air) for inverting the tube lining material 1 to the storage container 20, and further below the storage container 20. The door 27 which can be opened and closed is hermetically attached, and the worker can open the door 27 by pulling a handle to inspect the inside of the storage container 20.

In addition, the tube lining material 1 wound around the reel 24 is a well-known tube lining material, Comprising: The outer surface is comprised by impregnating the non-hardened liquid thermosetting resin in the tubular resin absorbent material hermetically covered with a plastic film. . As the plastic film, films such as polyethylene, vinyl chloride, vinylon, polyurethane, nylon, polypropylene, and polyethylene-nylon copolymer are used, and nonwoven fabrics such as polyester, nylon, acrylic, and vinylon are used as the tubular resin absorbent. do. As the uncured liquid thermosetting resin impregnated with the tubular resin adsorbent, thermosetting resins such as unsaturated polyester resins and epoxy resins are used. The inner surface of the tube lining material 1 may also be hermetically covered with the same plastic film as the outer surface.

In this embodiment, the pipe lining material 1 is inserted in the pipe line 3 which is inverted from the manhole 2 extending in the vertical direction and extends in a direction (horizontal direction) that is substantially orthogonal to the manhole 2. do. Therefore, the pipe lining material 1 inverted by the reversal nozzle 30 is bent by approximately 90 degrees at the lower part of the manhole 2 and inserted into the conduit 3, so that a large friction occurs at the direction change part and thus the It was becoming resistance. Therefore, in the present invention, the pressing apparatuses 40 and 50 are used to facilitate the change of direction (flexion) of the pipe lining material.

The crimping device 40 includes an attachment plate 41 attached to the lower portion of the manhole 2, as shown in Figs. 3 (a), (b), and 4 (a) and (b), and this attachment. An adjustment member 43 having a screw shaft 42 fixed to the plate 41, adjustment rods 43a and 43b screwed with the screw shaft 42, and fixed to the adjustment member 43. The end portion 44a on the side opposite to the fixed end of the pressing member 44, having a pressing member 44, is rotatably attached to the receiving member 45 fixed to the pressing plate 46 for pressing the tube lining material 1. Are bearing. The attachment plate 41 is comprised as a disc which has a curvature substantially corresponded to the curvature of the inner surface of the manhole 2, and the crimping plate 46 is inverted and made into the cylindrical shape of the outer surface of the tube lining material 1 It is a plate-shaped member curved at a curvature substantially corresponding to the curvature.

As shown in Fig. 4A, the attachment plate 41 of the pressing device 40 is attached to the inner wall of the manhole 2, and the pressing plate 46 is brought into close contact with the tube lining material 1, so that the operator adjusts it. When the adjusting member 43 is rotated in the clockwise direction through the rods 43a and 43b, the adjusting member 43 is screwed with the screw of the screw shaft 42, whereby the adjusting member 43 and the fixing member 43 are fixed thereto. The crimping member 44 moves in the horizontal direction (the right direction in Figs. 3 and 4) as shown in Fig. 4B. Since the end portion 44a of the pressing member 44 is axially rotatably supported by the receiving member 45 fixed to the pressing plate 46, the pressing plate 46 is turned to the right by rotating the adjusting member 43. Direction, and the pipe lining material 1 can be crimped to the right direction. Moreover, by rotating the adjusting member 43 in the reverse direction, the pressing plate 46 can be moved in the reverse direction (left direction).

The crimping device 50 includes an air cylinder 51 having a piston 52 and a piston rod 53, as shown in Figs. 5 (a), (b), and 6 (a) and (b). Of the support member 54 with the screw receiving member 56 screwed to the tip of the piston rod 53, the pressing member 55 fixed to the support member 54, and the support member 54. It has a guide roller 58 attached below through the strut 57. The pressing member 55 has a shape obtained by dividing the truncated cone up and down by about one third in the vertical direction, and has a curvature capable of wrapping the inverted tube lining material. And the bus bar 55a of the truncated cone seen when the crimping | compression-bonding member 55 is seen from the side surface is inclined at a predetermined angle, and it is easy to bend a pipe lining material to the direction of a pipe line.

In the crimping device 50 having such a configuration, as shown in Fig. 6 (a), the crimping member 55 inserts the tube lining material 1 into which the reversal nozzle 30 extends, i.e., is inserted inverted in the vertical direction. ), The presser 50 is moved on the conduit 3, and in this state, when compressed air is supplied to the cylinder chamber on the right side as shown in Fig. 6 (b), the piston 52 And the piston rod 53 moves in the left direction, and the support member 54 and the crimping member 55 fixed thereto are guided into the guide roller 58 in the conduit 3 so that the conduit 3 extends. The tube lining material 1 can be bent from the vertical direction to the horizontal direction by moving in the horizontal direction. When compressed air is supplied to the cylinder chamber on the left side of the air cylinder 51, the pressing member 55 can move to the position shown in Fig. 6A.

Below, the process of lining a pipeline using a pipe lining material is demonstrated.

The reversing apparatus is normally mounted in a truck, and one end of the tube lining material 1 is fixed to the reel 24, the electric motor is driven to be wound in a roll shape on the reel 24, and the storage container 20 is provided. ) Is stored. As shown in Fig. 2, the other end 1a of the tube lining material 1 is guided to the vicinity of the opening of the reversal nozzle 30, and is folded outward, so as to be sealed by a band or the like on the outer periphery of the opening end of the reversal nozzle 30. Is attached. The inversion device is arranged at a position in which the inversion nozzle 30 is perpendicular to the manhole 2 while being mounted on a truck, and forms a scaffold 4 to support the inversion nozzle 30.

Then, compressed air is supplied into the storage container 20 through the duct 26, and this fluid pressure (compressed air pressure) acts on the folded end 1a of the tube lining material 1, thereby providing the tube lining material 1 ) Is rewound from the reel 24, taken out from the storage container 20, inverted by the inversion nozzle 30, and inserted downward in the manhole 2 in the vertical direction. At this time, the electric motor operates as a generator, and the braking is applied to the reverse rotation of the reel 24, that is, to withdraw the tube lining material 1.

The tube lining material 1 inverted and inserted into the manhole 2 is inserted into the pipe line 3 bent in the horizontal direction with respect to the vertical direction in which the inversion nozzle 30 extends. In the bent portion where the manhole 2 and the conduit 3 intersect, when the thickness of the lining material is large or when the weight is increased by the large-diameter lining material, a large friction occurs and becomes resistance to reversal. By using the crimping device 40 and the crimping device 50, the insertion of the pipe lining material 1 into the pipe 3 is assured.

Therefore, the crimping device 40 has the attachment plate 41 attached to the inner wall of the lower part of the manhole 2, and the crimping device 50 supplies the compressor etc. which supply compressed air to the air cylinder 51, and the like. 2 and 7 together with the box 5 housed therein, the upper right end of the crimping member 55 is disposed at a position in the conduit 3 close to the inner wall surface of the manhole 2.

The operator rotates the pressing plate 46 by rotating the adjusting member 43 when the pipe lining material 1 is inverted and inserted into the manhole and moved to the position of the pressing plate 46 of the pressing apparatus 40. As shown in Fig. 4 (b), the pipe lining material 1 is brought into close contact with the right inner wall surface of the manhole 2 by moving in the right direction.

Thus, the tube lining material 1 biased to the right direction is guided along the bus bar direction inside the curved pressing member 55 of the pressing apparatus 50, as shown in FIG. Thus, compressed air is supplied into the air cylinder 51, the pressing member 55 is continuously moved to the left, and the pipe lining material 1 is pressed in the insertion direction (horizontal direction) of the pipe. By this crimping, the pipe lining material 1 is smoothly bent from the vertical direction to the horizontal direction, and is inserted into the pipe line 3 by changing the direction. This state is shown by two types of virtual lines in FIG.

Instead of continuously moving the pressing member 55 by the air cylinder, the pressing member 55 may be moved to the left in a stepwise manner to confirm that the pressing member 55 is reliably switched, and then the movement of the pressing member 55 may be stopped. In addition, when only the crimping device 50 can smoothly change the direction of the tube lining material 1, the use of the crimping device 40 can be omitted. However, when the crimping device 40 is used, the pipe lining material 1 is crimped in the direction opposite to the insertion direction into the conduit before bending, as indicated by the upward arrow in FIG. In addition to the pressing in the insertion direction (lower arrow), the bending of the tube lining material is smooth and secure. Furthermore, by changing the attachment position of the attachment plate 41 of the crimping device 40 according to the thickness, diameter, etc. of the tube lining material 1, it is possible to adjust the position in the up-down direction, so that the pressing force acting in the reverse direction is applied. You can change the position to make the turn more certain. By this structure, even a large diameter pipe lining material (for example, 350-800 mm in diameter) can be smoothly diverted.

In addition, when the plastic film is not coated on the outer surface (inner surface before inversion) of the inverted tube lining material 1, the impregnated thermosetting resin is exposed, so that the pressing plate 46 and the pressing member 55 are exposed. When the resin may adhere to the inner surface of the substrate, the protective cover may be detachably installed on the inner surfaces of the pressing plate 46 and the pressing member 55 to change the protective cover every time it is used.

In this way, the pipe lining material 1 is changed in the direction in which the pipe line 3 extends, and is inserted in the pipe line 3 sequentially while being reversed. If necessary, the pressing plate 46 and the pressing member 55 are returned to their original positions.

When the pipe lining material 1 is inverted and inserted into the pipe line 3 over a predetermined length, the reversal nozzle 30 and the attachment pipe 60 are accommodated in the storage container 20 (the conduit 22 and the storage container 20). In some cases).

As shown in Figs. 9 and 10, the attachment pipe 60 is a cylindrical member having flanges 60a and 60b above and below, and the flange 60a is airtight through a plurality of clamps 73. It is hermetically attached to the flange 80a of the cover 80, and the flange 60b of the attachment pipe 60 is connected to the flange 30c of the nozzle cone 30b through a plurality of bolt nut fixing means 72. ) Is hermetically attached.

On the side of the attachment pipe 60, there are attached ducts 61 and 62 for guiding the fruit supply hose 70 and the fruit discharge hose 71 therein, and an air supply hose for supplying compressed air ( An attachment hole 63 for attaching an illustration (not shown) and an attachment hole 64 for attaching an air discharge hose (not shown) for discharging air are formed. Both the ducts 61 and 62 and the attachment holes 63 and 64 are hermetically sealed with a cap or the like before each hose is attached.

After the reversal nozzle 30 and the attachment pipe 60 are separated from the storage container 20, the pressure cover 80 is attached to the upper portion of the attachment pipe 60, and compressed air is supplied therein. Since the pressure cover 80, the attachment pipe 60, and the reversal nozzle 30 have a closed structure as a whole, the pipe lining material 1 attached to the reversal nozzle 30 is expanded and the inner wall surface of the conduit 3 is expanded. It will be in close contact with.

In this state, as shown in Fig. 10, the fruit supply hose 70 and the fruit discharge hose 71 are introduced into the manhole 2 and the conduit 3 from the sides of the attachment pipe 60 through the ducts 61 and 62. It introduces and connects the other end of the fruit supply hose 70 to a fruit supply source (not shown). Since the window 81 having the transparent acrylic plate 82 is attached to the upper portion of the pressure cover 80, the worker has a pipe line in which the fruit supply hose 70 and the fruit discharge hose 71 are reversed through the window. Check whether it is smoothly introduced into the pipe lining material. At this time, since the hoses 70 and 71 are introduced from the side of the attachment pipe 60 not from the top, the hose introduction state through the window 81 is easily monitored or confirmed.

After confirming that each of the hoses 70 and 71 are inserted into the pipe, the fruit is supplied to the pipe lining material 1 through the fruit supply hose 70. As the fruit, there is hot water or steam, and as shown in Fig. 8, hot water or steam is sprayed to the inverted tube lining material 1 in a mist state through the jet port 70a formed in the hose 70. Thereby, the tube lining material 1 is heated, and since the thermosetting resin impregnated in the tube lining material 1 is heat-cured by heat, the inner surface of the pipe line 3 is lined by the thermosetting pipe lining material 1. To be restored. After the tube lining material 1 is thermoset, air is discharged to the outside through the air discharge hose.

Moreover, in the case of hot water, it can also be showered without making it into a mist state, and hot water or steam is discharged from the tip of the hose 70, without blowing out as a mist, and hot water or steam is introduced into the inside of the tube lining material. The tube lining material may be thermally cured by being filled.

The hot water used for heating is discharged to the outside through the discharge hose 71, can be circulated to return to the fruit supply source.

In addition, as shown by an imaginary line in FIG. 9, the attachment pipe 60 can attach ducts 65 and 66 of a different diameter so that the fruit supply (discharge) hose of a different diameter can be attached. Further, a plurality of air supply hose attachment holes and air discharge hose attachment holes may be formed on the side of the attachment pipe 60.

In the above embodiment, the crimping device 50 may be a hydraulic cylinder instead of an air cylinder, or the crimping member 55 may be moved using another driving source, for example, a motor.

Moreover, the compressed air for reversely inserting the tube lining material is not supplied from the duct 26 provided in the storage container 20, but through the air supply hose attached to the attachment hole 63 formed in the attachment pipe 60. You may supply.

In addition, the pressure cover 80 may cover the whole upper part of the attachment pipe | tube 60 as a flat transparent acrylic plate instead of the bowl shape shown in FIG. In this case, a large transparent window can be obtained, and the introduction state of the hose or the like can be better observed or monitored.

According to the present invention, after the reverse insertion of the tube lining material into the pipeline, the attachment pipe is separated from the storage container, the upper part of the attachment pipe is covered with a lid, and then the fruit supply hose is reversed from the side of the attachment pipe. Since it is made to be introduced inside, it is easy to insert a hose and the upper part of an attachment pipe has only the cover which covers an attachment pipe, and the effect that a hose introduction state can be monitored well from the upper part of an attachment pipe is acquired. .
