Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a tube inverting tube reversing apparatus for tube-guiding receptacle, more particularly, it is possible to reverse the reinforcement tube without installing the winding roller in which the reinforcement tube is wound in a separate chamber, The present invention relates to a tube reversing tube accommodating tube for accommodating a tube.

Generally, when various kinds of pipelines such as water, sewage, gas, electricity, communication, oil pipeline, seawater pipe are deteriorated or broken, various types of industrial piping such as piping of reinforcing tubes into pipelines and curing with steam heat to form new pipes There is a hardened pipe lining method. In order to perform such a method, a reinforcing tube reversing device for inverting the reinforcing tube while pushing the reinforcing tube toward the inside of the pipe is indispensably required.

Hereinafter, a conventional reinforcement tube reversing device will be described in detail with reference to the accompanying drawings.

1 is a schematic view of a conventional reinforcement tube reversing device.

1, the reinforcing tube 30 wound around the take-up roller 40 is inserted into the duct 10 through the manhole 20 to reinforce the inside of the duct 10 using the reinforcement tube 30, ). The winding roller 40 is installed in the chamber 50 so that the reinforcing tube 30 can be brought into close contact with the inner wall of the conduit 10, Blow high pressure air into the inside. The reinforcing tube 30 is in contact with the inside of the conduit 10 while being inverted by the high-pressure air introduced into the chamber 50.

When the reinforcing tube 30 is in close contact with the inner wall of the conduit 10, high-temperature steam is introduced into the reinforcing tube 30 to cure the reinforcing tube 30. By using the reinforcement tube reversing device as described above, it is possible to reinforce the pipeline 10 without replacing the existing pipeline 10 or excavating the ground, thereby reducing the cost of repairing the pipeline 10 The time required for repairing the pipeline 10 can be shortened.

However, in such a conventional reinforcing tube reversing device, a chamber 50 having a very large size is indispensably required to blow high-pressure compressed air into the reinforcing tube 30, and the internal pressure of the chamber 50 The capacity of the air compressor 60 is required to be increased. In the case of using a conventional reinforcing tube reversing device, only the reinforcing tube 30 wound on the take-up roller 40 can be drawn into the duct 10, Since the pipe 30 can not be drawn into the chamber 50 when the pipe 30 is wound, the pipe 10 having a very long length can not be repaired at a time.

In order to cure the reinforcing tube 30, a separate steam supply pipe (not shown) must be inserted into the manhole 20 to introduce high-temperature steam into the reinforcing tube 30. In this case, The steam is not smoothly filled at the end of the reinforcing tube 30, so that the hardening of the reinforcing tube 30 may be non-uniform for each part. In the prior art, when the reinforcement tube 30 is completely cured, the steam filled in the reinforcement tube 30 is directly discharged to the atmosphere. In this case, since the steam emitted is visually confirmed, .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a reinforcement tube reversing device according to the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 2 and 3 are an exploded perspective view and a cross-sectional view of the reinforcement tube reversing device according to the present invention, and FIG. 4 is a cross-sectional view showing a shape in which a reinforcement tube is mounted on the reinforcement tube reversing device according to the present invention.

The reinforcement tube reversing device according to the present invention is a device for inverting the reinforcement tube 30 into the pipeline 10 embedded in the ground and then curing the reinforcement tube 30 so that the pipeline 10 is inserted into the reinforcement tube 30 Even if the winding roller 40 wound with the reinforcing tube 30 is not positioned inside the high-pressure chamber, the compressed air is introduced into the reinforcing tube 30, So that it can be reversed.

That is, the reinforcing tube reversing device according to the present invention includes a main pipe 100 having a hollow pipe shape, a putting guide pipe 200 and a discharge guide pipe (not shown) coupled to both ends of the internal flow path of the main pipe 100 300, and a reinforcing tube 30, and is made of a material having a ductility and a restoring force equal to or greater than a reference value, so that the inner end of the introduction guide pipe 200 and the inner end of the discharge guide pipe 300 A pressure leakage preventive tube 400 connecting the inner ends of the main pipe 100 and the main pipe 100 and having a tip end connected to the end of the main pipe 100 on the side where the discharge guide tube 300 is coupled, A pipe 500, and an anti-air supply pipe 510 for supplying compressed air to the inner space of the end pipe 500.

The injection guide pipe 200 and the discharge guide pipe 300 are coupled such that their outer surfaces are in close contact with the longitudinal inner side surfaces of the main pipe 100. The inner diameter of the inner pipe toward the inside of the main pipe 100 Is smaller than the inner diameter of the main pipe (100). The pressure outflow preventing tube 400 connecting the inner end of the injection guide pipe 200 and the inner end of the discharge guide pipe 300 is maintained at a distance from the inner side of the main pipe 100 .

4, the end of the reinforcing tube 30 for repairing the conduit 10 sequentially passes through the injection guide tube 200, the pressure leakage preventing tube 400, and the discharge guide tube 300, That is, turned upside down, and tightly joined over the entire outer edge of the end pipe 500. [ Accordingly, when high-pressure air is introduced through the semi-dedicated air supply pipe 510 and the inner pressure of the end pipe 500 is increased, the reinforcement tube 30 is continuously inverted and pushed to the tip side (right side in FIG. 4) .

In order for the reinforcing tube 30 to be reversed more quickly and reliably, the inner pressure of the end pipe 500 must be increased. The high-pressure air introduced into the end pipe 500 is reinforced with the pressure- When the air flows out through the space between the tubes 30 to the rear end side (left side in FIG. 4), there is a problem that the inner pressure of the end pipe 500 is lowered, that is, the reinforcing tube 30 is not reversed.

The reinforcing tube reversing device according to the present invention can prevent the high pressure air in the end pipe 500 from being discharged to the outside through the pressure relief tube 400, And is pressed against the outer surface. That is, the reinforcement tube reversing device according to the present invention preferably includes an air supply pipe 110 for sealing to provide compressed air to the inner space of the main pipe 100.

Since both sides of the inner flow path of the main pipe 100 are blocked by the introduction guide pipe 200 and the discharge guide pipe 300, high pressure air is introduced into the main pipe 100 through the air supply pipe 110 for sealing The inner pressure of the main pipe 100 is increased and the pressure leakage preventing tube 400 is closely attached to the outer surface of the reinforcing tube 30 passing through the pressure leakage preventing tube 400. When the pressure relief tube 400 is in close contact with the outer surface of the reinforcement tube 30 as described above, the high pressure air in the end tube 500 is discharged through the space between the pressure relief tube 400 and the reinforcement tube 30 There is an advantage that the reinforcing tube 30 can be reversed more quickly and reliably.

Since the frictional force between the pressure relief tube 400 and the reinforcement tube 30 increases when the pressure relief tube 400 is in close contact with the outer surface of the reinforcement tube 30, There may be a case where it can not pass smoothly through the inside of the tube 400. The reinforcing tube reversing device according to the present invention is characterized in that the reinforcing tube reversing device according to the present invention includes a reinforcement tube 30 which is inserted into the pressure outflow preventive tube 400 so as to reduce frictional force between the pressure relief tube 400 and the reinforcing tube 30, An oil application unit (not shown) for applying lubricating oil may be further provided. It is preferable that the lubricating oil is applied to the outer surface of the reinforcing tube 30 and the type of the lubricating oil is appropriately selected according to various conditions such as the material and shape of the reinforcing tube 30 and the pressure leakage preventing tube 400.

5 is a use state diagram of the reinforcement tube reversing device according to the present invention.

Since the pressure for reversing the reinforcing tube 30 is not formed around the take-up roller 40 but is formed inside the end pipe 500 through which the reinforcing tube 30 passes, 5, the winding roller 40 on which the reinforcing tube 30 is wound can be exposed to the atmosphere without being located in a separate chamber.

That is, when the reinforcing tube reversing device according to the present invention is used, even if a very large amount of the reinforcing tube 30 is wound around the winding roller 40, it does not affect the reversal of the reinforcing tube 30 at all. It is possible to invert a large amount of the reinforcing tube 30 while flowing the reinforcing tube 30 to the inside of the conduit 10, that is, it is possible to repair the very long conduit 10 at a time.

In order to raise the pressure inside the chamber 50 beyond the reference value, as in the conventional reinforcement tube reversing device shown in FIG. 1, a large amount of compressed air is supplied to the chamber 50, (50), it takes a lot of cost and time. However, since the reinforcing tube reversing device according to the present invention can stably reverse the reinforcing tube 30 by raising the inner pressure of the end pipe 500, which is very small in size compared to the chamber 50, The amount of the compressed air is remarkably reduced and the cost and time required for reversing the reinforcing tube 30 can be saved.

Since the size of the internal pressure of the end pipe 500 and the size of the internal pressure of the main pipe 100 are different from each other, a compression pump for supplying compressed air to the end pipe 500 through the anti- It is preferable that the compression pump 80 for supplying the compressed air to the main pipe 100 through the air supply pipe 110 and the air supply pipe 110 for sealing is independently controlled.

6 is a cross-sectional view of a second embodiment of a reinforcement tube reversing device according to the present invention.

After the reinforcing tube 30 is adhered to the entire inner wall of the pipeline 10 requiring repair, the supply of compressed air to the inside of the end pipe 500 is stopped to stop the reversing of the reinforcing tube 30. However, since the reversing of the reinforcing tube 30 is not stopped immediately after stopping the supply of the pressurized air, and the reversal continues to some extent until the internal pressure of the reinforcing tube 30 falls below the reference value, Resulting in waste.

The reinforcing tube reversing device according to the present invention is used to prevent the waste of the reinforcing tube 30, that is, to prevent the reversing of the reinforcing tube 30 immediately when the user desires, And may be provided with a shielding door 600 capable of being transported in a direction transverse to the inside of the vehicle. 6, when the shielding door 600 is operated to cross the inside of the end pipe 500, the reinforcing tube 30 passing through the inside of the end pipe 500 is inserted into the inside of the end pipe 500 (The lower side in FIG. 6), so that the reversing of the reinforcing tube 30 can be immediately stopped.

At this time, although the shielding door 600 is shown as being raised and lowered by the rack and pinion in this embodiment, the transfer of the shielding door 600 can be changed and applied in various ways.

In order to allow the operator to visually confirm whether the reversal tube is normally reversed, the perspective glass 700 may be mounted inside the distal pipe 500. The user views the inside of the reinforcing tube 30 while visually checking the internal state of the reinforcing tube 30 through the perspective mirror 700, .

7 and 8 are a cross-sectional view and a use state view of a reinforcing tube reversing device according to a third embodiment of the present invention.

The reinforcing tube 30 which is inverted by the compressed air and brought into close contact with the pipeline 10 is cured by the high temperature steam supplied to the inside. When the high temperature steam is supplied around the manhole 20, The tube 30 can be completely cured, but the reinforcing tube 30 at a point remote from the manhole 20 can be hardened.

In order to solve the above problems, the reinforcing tube reversing device according to the present invention is configured such that the outlet end of the steam supply pipe 800, which provides high-temperature steam when the reinforcing tube 30 is inverted to the rear end, As shown in FIG. That is, in the reinforcement tube reversing apparatus according to the present invention, the steam supply pipe 800 may be connected to the rear end of the reinforcement tube 30 as shown in FIG. The steam supply pipe 800 is connected to the reinforcing tube 30 by various kinds of connection means as well as the connection link 810 shown in the present embodiment as long as the outlet through which the steam is discharged can be separated from the reinforcing tube 30 .

The steam supply pipe 800 is connected to the rear end of the reinforcing tube 30 such that the inlet guide pipe 200, the pressure outflow prevention tube 400, the discharge guide pipe 300, The steam supply pipe 800 is positioned at the innermost inner space of the reinforcement tube 30 when the reinforcement tube 30 is extended to the end so that the high temperature steam supplied through the steam supply pipe 800 The reinforcing tube 30 is gradually filled from the inside toward the manhole 20 side so that the entire reinforcing tube 30 can be uniformly cured.

At this time, when the steam pushed toward the manhole 20 is released to the atmosphere, the steam emission can be visually confirmed, and thus there is a problem that not only the appearance is bad but also various complaints are generated. Therefore, as shown in FIG. 8, the reinforcing tube reversing device according to the present invention further includes a steam recovery pipe 900 for recovering the steam in the reinforcing tube 30 located in the vicinity of the manhole 20 to the boiler 910 . The steam recovered by the boiler 910 is set to pass through the water in the boiler 910. Moisture contained in the steam is collected in the boiler 910 and only air is discharged into the atmosphere. It is not confirmed by the naked eye, and there is an advantage that the aesthetic problems and complaints mentioned above are all solved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention.
