Since the pressing force can be adjusted in more detail, it is possible to uniformly insert the repair material, excluding the area where the resin will not be impregnated, according to the length of the tube to which the repair material is to be injected. Since it is variable based on the measured values of a plurality of load cells, it is possible to reduce the input error of the repair material, and it is possible to selectively impregnate the inverted and non-inverted tubes by providing a pressurizing part to each of the stacked conveyors spaced apart upwards, The present invention relates to a tube impregnation device for conduit repair, which can save installation space of equipment for impregnating inverted and non-inverted tubes in one resin impregnation device.

In general, water and sewage pipes that move household water, sewage and rainwater are buried underground, so if they are buried for a long time, problems such as hardness decrease, cracks in the joints, leakage of water and foreign matter inflow due to deterioration and cracking occur. Sediment of sewage and rainwater is deposited by the pipe, and rust may occur due to corrosion inside the pipe.

In order to solve this problem, conventionally, buried water and sewage pipes were excavated to replace the whole, but the replacement of these pipes is consuming a lot of cost and time, so recently, a non-excavation type repair method that repairs without excavating a pipe is widely used. Has become.

This non-drilling pipe repair method proceeds by repairing cracks in the pipe by moving the tube to the inside of the pipe and then expanding and hardening it.It is largely reversed insertion type and traction depending on the method of moving the tube to the inside of the pipe. It is divided into insertion type.

The traction insertion method is a method in which a reinforcement in the form of a tube is pulled into an old pipe and then expanded in the outer diameter direction by applying pneumatic pressure to the inner diameter surface of the reinforcing member, and steam is applied into the reinforcement material to heat cure while the reinforcement is in close contact with the inner wall surface of the pipe. In the reverse insertion method, the reinforcement in the form of a tube is pulled to the inlet of the pipe, and then the reinforcement is inverted and expanded by pneumatic pressure, so that the reinforcing material is in close contact with the inner wall of the pipe, and steam is applied into the reinforcing material to heat cure.

All of these repair methods use a soft tube, and at this time, the soft tube is impregnated with a thermosetting resin or a UV curable resin.

Conventionally, a roller is provided on a conveyor to impregnate the tube with resin, and as the tube is moved between the roller and the conveyor, the resin injected into the tube is pushed to the rear by the roller and impregnated evenly throughout the tube. Utilized.

However, the tube needs a section in which a certain length of resin is not impregnated for packaging and shipment at that point and end point, or for coupling with various mechanical devices and pipes during construction. There was a problem of having to rely on the skill level of the worker because there is no means to determine whether or not.

Therefore, there is a need to develop a device capable of accurately impregnating a resin repair material with a desired length inside the tube.

The main motor 123 is preferably a DC step motor so as to control the exact amount of rotation, but it may be an AC motor when a separate rotation amount detecting means is provided, but is not limited thereto.

The main lifting shaft 124 rotates forward or reverse by receiving rotational force from the main motor 123, so that the main lifting block 122 is raised when the main motor is rotated, and the main lifting block 122 is lowered when rotating in the reverse direction. A thread is formed on the outer periphery.

The main lifting shaft 124 is coupled to the rotating shaft of the main motor 123 in the longitudinal direction, and the outer circumferential thread is engaged with the thread formed on the inner circumference of the main lifting block 122.

The main lifting block 122 serves to allow the main roller 121a to be rotatably mounted, and to allow the main roller 121a to rise or fall when the main motor 123 rotates.

To this end, the main lifting block 122 has a thread formed at the inner periphery of the groove drawn inward from the top to engage the thread of the main lifting shaft 124, and the main roller 121a is rotatably coupled at the lower end. The main lifting block 122 and the main motor 123 may be replaced with a lifting structure that provides the same function. For example, a pneumatic or hydraulic cylinder may be installed, and the main roller 121a may be elevated to adjust the distance between the main roller 121b and the main support roller 121b. Therefore, the main lifting block 122 and the main motor are used as terms representing the lifting structure.

The above-described main motor 123, the main lifting shaft 124, and the main lifting block 122 are provided in a pair in the direction of both sides of the end of the base conveyor 111 in one end direction, so that between the pair of main lifting blocks 122 It may be configured to be mounted on both ends of the main roller (121a).

However, the main motor 123, the main lifting shaft 124, the main lifting block 122 is provided alone, and the lower end of the main lifting block 122 is expanded in the lateral direction and then bent downward between the bent portions. It may be configured to be mounted on the main roller (121a). In this case, a sliding shaft that prevents rotation of the main lifting block 122 so that the left and right alignment of the main lifting block 122 is not disturbed when the main motor 123 rotates is provided through the main lifting block 122. The main lifting block 122 is configured to rise or fall along the sliding shaft when the main motor 123 rotates, but the left and right rotation is prevented by the sliding shaft.

The main roller 121a presses the first tube 10 when the first tube 10 passes, so that the repair material 1 injected into the first tube 10 can pass through a certain thickness. It serves, and for this purpose, it is rotatably mounted on the main lifting block 122.

It is preferable that a line connecting both ends of the main roller 121a in the longitudinal direction is in a state perpendicular to the longitudinal direction of the base conveyor 111.

On the other hand, the main roller (121a) may be configured to be directly adjacent to the upper surface of the base conveyor 111, but when provided in the one end direction more than one end of the base conveyor 111, that is, one end of the base conveyor 111 A main support roller 121b may be further provided to properly pressurize the first tube 10. And, at this time, the main support roller (121b) may be rotatably mounted to the main support (125).

This main roller (121a) is a separation distance from the upper surface of the base conveyor 111, or a separation distance from the main support roller (121b), the pressing force applied to the first tube (10) is adjusted, the main roller (121a) In order to determine the pressing force of the base load cell 140 is provided.

The base load cell 140 is provided at the lower end of the upper surface of the base conveyor 111 in the direction of the other end of the main pressing part 120 and serves to measure the weight applied to the base conveyor 111. This base load cell 140 is provided at the bottom of the top surface of the inclined base conveyor 111b and the bottom of the top surface of the parallel base conveyor 111a as shown in FIGS. 1 to 3 to measure the variable weight of the transfer roller, through which You can check the amount of remaining resin that is not impregnated in the introduced resin.

Meanwhile, a plurality of base load cells 140 may be provided and configured to measure weight applied to the base conveyor 111 at multiple locations. In this case, the base load cell 140 includes a first base load cell 141 and a second base load cell 142 spaced apart from the first base load cell 141 in the direction of the other end of the first base load cell 141. . More specifically, the first base load cell 141 is disposed at the point of the parallel base conveyor 111a that is flat on the ground, and the second base load cell 142 is disposed at the point of the inclined base conveyor 111b inclined to the ground. It is bent and installed at the point where the slope starts. The first base load cell 141 is installed in more than one, and is installed close to the bent portion of the parallel base conveyor 111a and is disposed with a mutual interval.

Accordingly, the base load cell 140 is installed near the bent base frame 110 and installed on different base conveyors 111a and 111b. This is because the resin (repair material) to be impregnated into the inclined inclined base frame 110b is driven around the inclined surface, and the weight of this part is measured to determine the amount of resin remaining without impregnation in the entire resin, and the remaining resin It is to adjust the main pressing part 120 so that the first tube can be uniformly impregnated with the exception of the impregnated surface.

The control unit serves to vary the pressing force of the main pressing unit 120 based on the measured value of the base load cell 140.

To this end, the control unit receives the measured values from the base load cell 140 and the base encoder, calculates the remaining transport length of the first tube 10 based on the measured values of the base encoder, and compares the calculated remaining transport length to the base load cell 140. ) By varying the pressing force of the main pressing part 120 as a ratio of the measured value, calculating the amount of the remaining first tube 10 and the amount of resin to be impregnated to calculate the entire tube (excluding the part where the repair material is not added) ) Is controlled so that the resin is impregnated as uniformly as possible.

For example, as a result of analyzing the measured value of the base encoder, it was found that the first tube 10 of 5 m was transferred out of the first tube 10 of 50 m, and the measured value of the base load cell 140 was 1/8. If it is reduced, since the repair material 1 remains 7/8 in the state that the remaining length of the first tube 10 is 9/10, if the first tube 10 is continuously transferred, the repair material 1 Does not reach the end of the first tube 10. Therefore, in this case, the controller drives the main motor 123 to rotate in reverse and lowers the main roller 121a to increase the pressure applied to the first tube 10. At this time, the driving amount of the main motor 123 is adjusted in real time so that the reduction ratio of the remaining transport length of the first tube 10 per unit time becomes the same as the reduction ratio of the remaining amount of the repair material 1.

At this time, the first tube 10 is a tube used in a reversal repair method, and has a shape that is inverted compared to the completion of construction during manufacture and impregnation. That is, during manufacture and impregnation, the nonwoven fabric layer in which the repair material 1 is absorbed is located on the innermost side, and the coating layer forming the inner flow path after construction is located on the outermost side. The first tube 10 requires a section in which the repair material 1 is not input at one end due to packaging shipment, coupling with a reversing device during construction, and input distance to the pipe during construction, and the other end It requires a section in which the repair material (1) is not put in about 6-20m. Therefore, the remaining length of the transfer of the first tube 10 should be interpreted as meaning only the section in which the repair material 1 is to be introduced, excluding the section in which the repair material 1 is not added.

The length of the remaining tube and the amount of maintenance material (resin) are calculated by the control unit to adjust the pressing unit, and at the same time are displayed to the operator on the display 128. The display is preferably installed in a location where there are many work objects, and in the drawing, it is shown next to the lifting block.

On the other hand, it may be difficult to uniformly press the repair material 1 only with the main pressing unit 120. The main pressurization unit 120 presses the first tube 10 and pushes the repair material 1 in the direction of the other end, and the first tube 10 remains in the first tube 10 while only a certain amount of the repair material 1 remains in the first tube 10. Even if it is allowed to pass through the pressurizing unit 120, the repair material 1 is unintentionally pushed by the main pressurizing unit 120 in the direction of the other end of the main pressurizing unit 120 and loaded by the pressure of the repairing material 1 This is because it can pass through the main pressing portion 120 in an appropriate amount or more. This is a common example of this in everyday life, for example, when pressing a toothpaste with your finger, or when pushing air from one side to the other to drain air from a tube, toothpaste that is loaded in the direction you push it. Alternatively, a fluid that passes backward is present even in a place that has already been pushed out unintentionally by the pressure of a fluid such as air.

Therefore, in the present invention, the other end of the main pressurization unit 120 in order to reduce the pressure of the repair material 1 pushed by the main pressurization unit 120 before pressing the first tube 10 from the main pressurization unit 120 The auxiliary pressing unit 130 is provided in the direction and configured to press the first tube 10.

The first base load cell 141 and the second base load cell 142 are installed on the bent side of the auxiliary pressing unit 130 and the base conveyor 111, and the parallel base conveyor 111a and the inclined base conveyor 111b It is provided at the bottom of the upper surface and serves to measure the weight of resin (repair material) applied to the parallel base conveyor 111a and the inclined base conveyor 111b, respectively. Since the base conveyor 111 has a bent portion and resins are collected around it, the amount of resin that has not yet been impregnated in the entire resin can be measured through the weight of this portion. In addition, since it is possible to check the amount of the remaining tube that has moved from the base encoder and not impregnated, the tube is impregnated as uniformly and uniformly as possible in the tube based on the information on the amount of the tube to be impregnated and the amount of resin remaining.

In the case of an inverted tube, if resin is impregnated with resin in the part that is connected to the compressor so that steam can be introduced during work, and the part left to be cut after work, it is difficult to repair the unused part (6m ~ 20m). There should be no resin impregnation. However, since there is no structure to prevent the movement of the resin in the tube, the resin may flow into the tube as it is and may be completely impregnated, and in this case, the tube may be defective.

At the beginning, resin can be inserted and impregnated after the interval required for maintenance work, but it is very difficult to control the amount of resin impregnated so that the resin does not enter the last part of the tube. This is because resin is already inserted in the tube, so it is difficult to know how much the amount of resin inserted into the tube is impregnated, and the length of the tube is longer than the length of the conveyor belt, making it difficult to know the amount of the remaining tube under the conveyor belt in one place. Because.

In the present invention, the amount of resin inserted into the tube, but not yet impregnated, can be accurately confirmed at the portion of the bent base conveyor 111 where the resin is collected, and the amount of the tube not impregnated in the base encoder can be known, so that the main pressure By controlling the portion 120 and the auxiliary pressing portion, uniform resin impregnation is possible in the region where the portion not to be impregnated in the remaining tube is controlled.

The control unit varies the pressing force of the main pressing unit 120 and the auxiliary pressing unit 130 based on the measured values of the first base load cell 141 and the second base load cell 142.

To this end, the control unit receives a measured value from the first base load cell 141 and the second base load cell 142 and the base encoder, calculates the remaining transport length of the first tube 10 based on the measured value of the base encoder, As the ratio of the measured values of the first base load cell 141 and the second base load cell 142 to the calculated remaining transport length, the remaining resin is added to the tube while varying the pressing force of the main pressing unit 120 and the auxiliary pressing unit 130 Allows to be uniformly impregnated within.

Since the role of the auxiliary pressurization unit 130 is to reduce the pressure of the repair material 1 that must be handled by the main pressurization unit 120, the control unit controls the pressing force of the auxiliary pressurization unit 130 below the main pressurization unit 120 It is desirable to be operated to do so.

On the other hand, the first tube 10 is a tube used for repairing an inverted pipe, and in the present invention, a configuration for impregnating the second tube 20, which is a tube used for repairing a non-reversing pipe, is also provided.

However, the bent portion of the upper frame 210 is made to be inclined only when the resin is inserted with the hinge 228 as the center, and is of a hinge type that rotates to be parallel to the ground after the insertion is completed. Such a hinge 228 rotates upward by a forward rotation of a motor (not shown) and parallel to the ground by a reverse rotation.

On the other hand, the upper pressing part 220 has a shape that can be moved in one or the other direction along the upper conveyor 211. For this purpose, an upper rail 227 provided in a longitudinal direction on one side of the upper frame 210 and the upper An upper driving part 226 which is moved along the rail 227 in the direction of one end or the other end, and an upper support 225 coupled to the upper driving part 226 to which the upper pressing part 220 is coupled are provided.

The upper support 225 serves to fix the upper pressing part 220, and for this purpose, it is coupled to one side of the upper driving part 226 and provided.

The upper load cell 230 is provided at the lower end of the upper surface of the upper conveyor 211 at the other end of the upper conveyor 211 and serves to measure the weight applied to the upper conveyor 211. Such an upper load cell 230 may be provided between the transfer rollers as shown in FIGS. 1, 4 to 6 and may be provided to contact the lower end of the upper surface of the upper conveyor 211, or provided at the bottom of the bearing on the mounting portion of the transfer roller. It may be provided to measure the variable weight of the conveying roller.

Meanwhile, a plurality of upper load cells 230 may be provided and configured to measure weight applied to the upper conveyor 211 at a plurality of positions. In this case, the upper load cell 230 is preferably provided in two places at one end and the other end of the upper conveyor 211.

The control unit receives the measured values from the upper load cell 230 and the upper encoder, calculates the remaining transport length of the second tube 20 based on the measured values of the upper encoder, and calculates the remaining transport length compared to the upper load cell 230 The pressing force of the upper pressing unit 220 can be varied as a ratio of the measured value of.

Alternatively, the control unit receives the measured value from the upper encoder, calculates the remaining transport length of the second tube 20 based on the measured value of the upper encoder, and applies the pressing force of the upper pressing unit 220 based on the calculated remaining transport length. Can be changed. This may be different from controlling the pressing force of the main pressing unit 120 and the auxiliary pressing unit 130 as a ratio of the remaining transport length of the first tube 10 and the measured value of the base load cell 140, which is the second tube. It is due to the characteristics of (20).

The second tube 20 is a tube used in a non-inverting repair method, and has the same phase when manufacturing, impregnation, and construction are completed. That is, when manufacturing, impregnation and construction are completed, the coating layer 21 forming the inner flow path is located at the innermost side, and the nonwoven fabric layer 22 is provided outside the coating layer 21, and is protected on the outside of the nonwoven fabric layer 22 Layer 23 is located. Unlike the first tube 10, the second tube 20 requires a section in which the repair material 1 is not injected at both ends of one side and the other side about 0.5 to 1 m. Therefore, the second tube 20 is larger than the first tube 10 even if the pressing force of the upper pressing unit 220 is finally adjusted after the end of the second tube 20 is seated on the upper conveyor 211 It becomes a composition without difficulty. For example, the amount of the repair material 1 to be initially input relative to the total length of the second tube 20 can be estimated experimentally, and corresponding to the total length of the second tube 20 and the input amount of the repair material 1 The initial pressing force of the upper pressing part 220 may be determined.

And, as a result of calculating the measured value of the upper encoder as shown in FIG. 5C, the control unit determines that the end of the second tube 20 is located between the end of the upper conveyor 211 in the direction of the other end and the upper load cell 230, The second tube 20 is pressed while moving the upper pressing part 220 in the direction of the other end. And, as shown in Figure 6d, when the repair material 1 pushed in the other direction by the upper pressing part 220 reaches the upper load cell 230 provided at the other end of the upper conveyor 211, the measurement from the upper load cell 230 The measured value increases gradually. In this state, when the upper pressurizing part 220 is further moved in the other direction, the measured value measured from the upper load cell 230 reaches the highest point and then descends, and at this point, the repair material 1 falls above the upper load cell 230. It is determined that it is located at and releases the pressing force of the upper pressing part 220. That is, the upper roller 221 is raised to prevent the upper roller 221 from contacting the second tube 20 any more. Thereafter, the control unit drives the upper driving unit 226 as shown in FIG. 6E so that the upper pressing unit 220 can be moved to the end in the direction of the other end of the upper conveyor 211 through the upper side of the upper load cell 230. Likewise, the pressing force of the upper pressing part 220 is raised again so that the upper roller 221 can press the second tube 20. Finally, the control unit drives the upper driving unit 226 so that the upper pressing unit 220 can be moved in one direction, and the pressing force of the upper pressing unit 220 at this time is based on the measured value of the upper load cell 230. Is calculated.

However, it is also possible that the upper load cell 230 is configured in plural as well as the lower load cell, and in this case, one upper load cell 230 and the upper pressing unit 220 in the direction of the other end of the initial position of the upper pressing unit 220 Adjacent to the provided, the other upper load cell 230 is provided near the other end of the upper conveyor 211 as described above, and the control unit transfers the second tube 20 based on the measured value of the upper encoder. The length is calculated and is operated to vary the pressing force of the upper pressing unit 220 as a ratio of the measured value of the upper load cell 230 provided adjacent to the upper pressing unit 220 to the calculated remaining transport length.

The state of use of the present invention may be divided into an impregnation configuration of the first tube 10 and an impregnation configuration of the second tube 20.

Looking at the impregnation configuration of the first tube 10, after mounting the first tube 10 on the upper surface of the base conveyor 111, by driving the base conveyor 111, one end of the first tube 10 is auxiliary pressurized. It should be located in the vicinity of the part 130. Then, after stopping the driving of the base conveyor 111, the repair material 1 is placed inside the first tube 10, that is, between the nonwoven fabric layers, using the repair material 1 injection hose h as shown in FIG. 3A. Inject. Then, the base conveyor 111 is driven again so that one end of the first tube 10 can be moved to the lower portion of the auxiliary pressing unit 130.

In addition, the control unit initially sets the pressing force of the main pressing unit 120 and the auxiliary pressing unit 130 according to the length of the first tube 10 and the amount of the injected repair material 1. Thereafter, the control unit varies the pressing force of the main pressing unit 120 and the auxiliary pressing unit 130 based on the measured values of the base encoder, the first base load cell 141 and the second base load cell 142.

Next, looking at the impregnation configuration of the second tube 20, after mounting the second tube 20 on the upper surface of the upper conveyor 211, the upper conveyor 211 is driven to one end of the second tube 20 It is positioned in the vicinity of the upper pressing part 220. And, after stopping the driving of the upper conveyor 211, as shown in FIG. 5A, between the nonwoven fabric layer 22 and the protective layer 23 of the second tube 20 using the repair material 1 injection hose h. Inject the repair material (1). At this time, the nonwoven fabric layer 22 of the second tube 20 is provided on the outside of the coating layer 21 differently from the first tube 10, so when looking at the cross section of the second tube 20 folded flat, it is protected from the upper direction. Layer 23-non-woven fabric layer 22-coating layer 21-coating layer 21-non-woven fabric layer 22-protective layer 23 in this order. Accordingly, the repair material 1 must be injected into the upper and lower portions of the nonwoven fabric layer 22 in the form as shown in FIG. 5A so that the repair material 1 can be injected into the entire nonwoven fabric layer 22.

When the injection of the repair material 1 into the second tube 20 is completed in this way, the control unit drives the upper conveyor 211 so that one end of the second tube 20 can be moved to the lower portion of the upper pressing unit 220. To be.

Then, the control unit initially sets the pressing force of the upper pressing unit 220 according to the length of the second tube 20 and the amount of the injected repair material 1. Thereafter, the control unit varies the pressing force of the upper pressing unit 220 based on the measured values of the upper encoder or the upper encoder and the upper load cell 230.

On the other hand, the control unit estimates the end position of the second tube 20 based on the remaining transport length calculated based on the measured value of the upper encoder, and the end position of the second tube 20 is the end of the upper conveyor 211 in the direction of the other end. When it is determined that it is between the and the upper load cell 230, the driving of the upper conveyor 211 is stopped.

In addition, the control unit drives the upper driving unit 226 as shown in FIG. 5C so that the upper pressing unit 220 can be moved in the direction of the other end of the upper conveyor 211. At this time, as shown in FIGS. 5D and 5E, when the measured value of the upper load cell 230 provided in the direction of the other end of the upper conveyor 211 gradually rises and falls, the controller releases the pressing force of the upper pressing part 220 The roller 221 is spaced apart from the second tube 20. And, after moving the upper driving part 226 to the end in the other end direction of the upper conveyor 211, the upper pressing part 220 increases the pressing force so that the upper roller 221 can press the second tube 20 again. do. In addition, the control unit drives the upper driving unit 226 as shown in FIG. 5F so that the upper pressing unit 220 moves in one direction and returns to the initial position. The pressing force at this time is calculated based on the measured value of the upper load cell 230, and is accumulated above the upper load cell 230 of the second tube 20 when the upper pressing part 220 is moved in one direction and moved to the initial position. The repair material 1 that was used is calculated to the extent that it can be uniformly present inside the second tube 20.

In addition, the impregnation operation of the first tube 10 and the impregnation operation of the second tube 20 may be performed simultaneously, and at this time, the first tube 10 and the upper conveyor discharged in the one end direction of the base conveyor 111 The second tubes 20 discharged in the direction of one end of 211 are discharged in the same direction. In this case, since the first tube 10 and the second tube 20 may be entangled with each other, a base loading portion in which the first tube 10 is loaded is provided in one direction of the base frame 110, and the base loading portion It is preferable that an upper loading portion is provided so as to be spaced apart from the base loading portion in the upper portion so that the second tube 20 is configured to be separately loaded. At this time, obviously, the upper loading part should be located above the upper roller 221. In addition, the upper loading portion may be configured in a lift shape so that the loaded second tube 20 can be carried out, so that it can be elevated.

In the present invention made of the above-described configuration, since the pressing force of the pressing unit is adjusted based on the amount of the remaining repair material 1 measured in the load cell, the area where the resin will not be impregnated according to the length of the tube to which the repair material 1 is to be introduced is excluded. And there is an effect that the repair material (1) can be added uniformly.

In addition, the present invention adjusts the pressing force of the pressurization unit as a ratio of the remaining length of the tube to the remaining maintenance material 1, so that the repair material 1 can be accurately inserted according to the length of the tube to which the repair material 1 is to be introduced. It works.

Further, according to the present invention, since the tube is pressurized as a plurality of pressurizing units, and the pressurizing force of each pressurizing unit is varied based on the measured values of the plurality of load cells, there is an effect of reducing the input error of the repair material 1.

In addition, in the present invention, since it is possible to selectively impregnate the reversing and non-reversing tubes by providing a pressing unit to each of the stacked conveyors spaced apart from above, it is possible to impregnate the reversing and non-reversing tubes in one resin impregnation device. It has the effect of saving the installation space of the equipment for use.
