Description

A kind of overturning lining repair equipment and method for pipeline repair and reinforcement

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 4, 2024, with application number 202410155945.4 and invention name “A flip lining repair equipment and method for pipeline repair and reinforcement”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of pipeline repair, and in particular to an overturning liner repair device and method for pipeline repair and reinforcement. Background Art

[0003] The room-temperature in-situ curing method is a trenchless repair technology for buried pipelines that has gradually begun to be used in recent years. It uses a 180-degree flip to place a hose impregnated with a matrix into the damaged original pipeline. Under expansion pressure, the inverted hose is tightly combined with the damaged original pipeline into a whole, and then left to cure at room temperature, thereby achieving the purpose of repair and reinforcement.

[0004] The use of room-temperature in-situ curing method to repair and reinforce pipelines involves multiple equipment and multiple links, so it often takes a long time to complete the construction.

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0062] Referring to Figures 1 to 16, an embodiment of the present invention provides a reversible lining repair equipment for pipeline repair and reinforcement, comprising a work vehicle 100, a power supply unit 700, a matrix mixing device 200, a hose impregnation and flattening device 300, a hose reversing device, and a mobile support 140. The work vehicle 100 is a vehicle that carries other equipment. Workers driving the work vehicle 100 can achieve the overall transfer of the reversible lining repair equipment, for example, from one construction site to another. The work vehicle 100 has a box-shaped body and a vehicle-mounted support frame 101 located at the rear of the vehicle. The box-shaped body provides a first storage space, which is provided with a dry hose material storage area, a matrix material storage area, and a guide sleeve storage area. It is easy to understand that the dry hose material storage area is used to store dry hoses 800 to be used, the matrix material storage area is used to store matrix materials 900 to be used, and the guide sleeve storage area is used to store guide sleeves 110 to be used. It should be noted that in order to show the equipment inside the vehicle, parts of the vehicle compartment are made transparent in Figures 1 and 2. The first accommodation space provided by the vehicle compartment should be able to be closed. For example, when the work vehicle 100 is in motion, the vehicle compartment door (not shown) should be closed to keep the vehicle compartment closed. Specifically, the vehicle compartment door is generally located at the rear of the vehicle compartment, and opening the door allows workers to enter and exit the vehicle compartment.

[0063] The power supply unit 700, the matrix mixing device 200 and the hose impregnation and flattening device 300 are all located in the above-mentioned first accommodation space. The matrix mixing device 200 is located in the first accommodation space near the front side of the vehicle, and the hose impregnation and flattening device 300 is located in the first accommodation space near the middle of the vehicle body. The position of the power supply unit 700 in the first accommodation space can be flexibly set as needed. For example, the power supply unit 700 can be set near the front side of the vehicle. The power supply unit 700 is used to provide power to the electrical equipment of the flip lining repair equipment.

[0064] The hose flipping device is used to flip and propel the hose, and includes a flipper 400 and an air pump 500. The air pump 500 can provide air pressure to push the hose forward. The mobile bracket 140 includes a bracket body and wheels 142 arranged at the bottom of the bracket body. It is easy to understand that the wheels 142 allow workers to easily push the bracket body to achieve the mobile function. The vehicle-mounted support frame 101 and the mobile bracket 140 are both used to support the flipper 400, corresponding to different construction methods. That is, the top of the vehicle-mounted support frame 101 is provided with a first mounting seat for detachably connecting to the flipper 400, and the top of the bracket body is provided with a second mounting seat for detachably connecting to the flipper 400. As shown in Figures 3 and 16, in the first construction method, the flipper 400 is fixedly mounted on the vehicle-mounted support frame 101, and in the second construction method, the flipper 400 is fixedly mounted on the mobile bracket 140.

[0065] The matrix mixing device 200 is used to provide mixed matrix material for impregnation. As shown in Figure 4 , a mixing chamber 201 of the matrix mixing device 200 is provided with an agitator driven by a stirring motor 204. The mixing chamber 201 is also provided with a discharge port 202. The discharge port 202 directly directs the mixed matrix into a dry hose 800 pre-placed on the hose impregnation and flattening device 300, thereby obtaining a State I hose 801. In a preferred embodiment, the inversion lining repair equipment further includes a vacuum device 600, which is located within the aforementioned first storage space and connected to the matrix mixing device 200 via a pipeline. As shown in Figure 4 , the mixing chamber 201 is provided with a vacuum connection port 203, which is connected to the vacuum connection port 203 via a pipeline. The vacuum device 600 is used to remove bubbles generated during the matrix stirring process, thereby improving the quality of the matrix provided by the matrix mixing device 200. Specifically, the mixing bin 201 is generally configured as an upright cylindrical barrel, with the stirring motor 204 located at the top of the mixing bin 201. A plurality of legs may be provided at the bottom of the mixing bin 201 to ensure that the mixing bin 201 is at a certain height relative to the floor of the vehicle compartment. In this way, the matrix in the mixing bin 201 can flow out of the discharge hole 202 under the action of gravity and be directly poured into the dry hose 800. Of course, in other embodiments, a discharge pipeline may be connected to the discharge hole 202, and a discharge pump may be provided on the discharge pipeline to transport the matrix in the mixing bin 201 into the dry hose 800.

[0066] After the dry hose 800 is infused with the mixed matrix, a State I hose 801 is obtained. The hose impregnation and flattening device 300 is used to flatten and impregnate the State I hose 801, thereby obtaining the State II hose 802. As shown in Figure 5, in a preferred embodiment, the hose impregnation and flattening device 300 comprises a frame, a first roller assembly, and a second roller assembly. The frame is provided with a transmission line running from the front to the rear of the work vehicle 100. The second roller assembly is located downstream of the first roller assembly on the transmission line, meaning that the State I hose 801 passes through the first roller assembly first and then the second roller assembly. The first roller assembly comprises at least two paired smooth rollers 302, and the second roller assembly comprises at least two paired grooved rollers 305. The smooth rollers 302 are used to flatten the hose and impregnate the matrix and hose, while the grooved rollers 305 provide a secondary, full impregnation of the matrix and hose, further ensuring the bond between the two.

[0067] The first pressing roller group and the second pressing roller group are driven by a power device such as a motor. In a preferred embodiment, the hose impregnation and flattening equipment 300 is provided with a first pressing roller adjustment device 303 and a second pressing roller adjustment device 306, wherein the first pressing roller adjustment device 303 can provide the first pressing roller group with the power required to rotate the smooth round roller 302, and is used to adjust the roller gap size of the smooth round roller 302; the second pressing roller adjustment device 306 can provide the second pressing roller group with the power required to rotate the grooved roller 305, and is used to adjust the roller gap size of the grooved roller 305.

[0068] Further preferably, a third roller group consisting of smooth round rollers 302 can be provided downstream of the second roller group to further flatten the hose. To facilitate adjustment of the orientation of the hose 801 in State I, the hose dipping and flattening apparatus 300 can be provided with a hose support 304. The hose 801 in State I is supported by the hose support 304 after exiting the first roller group and then entering the second roller group. To reduce the movement resistance of the hose 801 in State I, the hose support 304 can include a rod and a roller mounted on the rod. The friction between the roller and the rod is much smaller than the friction between the roller and the hose 801 in State I. This reduces the movement resistance of the hose 801 in State I and reduces wear on the hose.

[0069] Further preferably, the transmission line of the hose impregnation and flattening apparatus 300 includes a first transmission section located upstream of the first roller group and a second transmission section located downstream of the second roller group. Both the first and second transmission sections are equipped with multiple unpowered conveying rollers 301. The end of the first transmission section away from the first roller group is arranged in an upward-curving, extending shape. Specifically, the unpowered conveying rollers 301 can include a rod and a roller mounted on the rod. The friction between the roller and the rod is much lower than the friction between the roller and the State I hose 801. As shown in Figures 1 and 5, because the end of the first transmission section away from the first roller group is arranged in an upward-curving, extending shape, the substrate in the State I hose 801 is less susceptible to backflow, thereby preventing the substrate from flowing out of the State I hose 801 away from the first roller group.

[0070] As shown in Figures 1 and 2, in a preferred embodiment, a vacuum suction pipeline device 106 is provided in the vehicle compartment, and the vacuum suction pipeline device 106 is connected to the vacuum extraction device 600, and is used to extract excess gas in the state I hose 801 that is being impregnated and flattened, so that the matrix can better fill the impregnated hose.

[0071] 6 to 13 , in a preferred embodiment, the turning machine 400 includes a sealing cylinder segment 410, a pressurizing cylinder segment and a sealing assembly 420, wherein the sealing assembly 420 is located between the sealing cylinder segment 410 and the pressurizing cylinder segment, one end of the sealing cylinder segment 410 is provided with an end plate 411 with an inlet pipe port 412, the interior of the sealing cylinder segment 410 is provided with at least one sealing body, and the sealing body can be deformed to make sealing contact with the hose; one end of the pressurizing cylinder segment is provided with a circular pipe outlet, and the outer wall of the pipe outlet is provided with an inflatable annular first expansion body 442; the sealing assembly 420 includes a first sealing plate 425, a second sealing plate 426 and a sealer 427, the sealer 427 is clamped between the first sealing plate 425 and the second sealing plate 426, the first sealing plate 425 and the second sealing plate 426 are both provided with a flat port for the hose to pass through, and the sealer 427 is provided with an inflatable second expansion body 428.

[0072] Before the hose is turned over and pushed forward, one end of the hose is first passed through the turning machine 400 from the pipe inlet 412, and then passed through the sealing cylinder section 410, the sealing assembly 420 and the pressurizing cylinder section in sequence and then passed out from the pipe outlet. Then, the end of the hose is turned over and put on the first expansion body 442 and fixed. In this way, a confined space is formed between the hose, the sealing assembly 420 and the pressurizing cylinder section. When the hose is turned over and pushed forward, the air pump 500 continuously injects air into the confined space, thereby using air pressure to push the hose forward and complete the turning during the forward process. Since the first expansion body 442 can be expanded by inflation to form different outer diameters, it can better adapt to a variety of hoses of different specifications. When one end of the hose is turned over and fixed to the first expansion body 442, in addition to using the first expansion body 442 to support the hose to fix the hose, a hoop or cable tie can also be set on the back side of the first expansion body 442 to further fix the hose. The second expansion body 428 of the sealer 427 can be expanded by inflation to form an inward squeeze, that is, the second expansion body 428 increases in volume and contacts the hose more closely. As shown in FIG12 , the second expansion body 428 can be specifically configured as a trapezoidal body.

[0073] As shown in Figure 7, in this embodiment, two end plates 411 are joined together to form a pipe inlet 412 in the middle. The body of the sealing cylinder segment 410 is provided with a flange structure that connects to the end plates 411. The end plates 411 are bolted to the body of the sealing cylinder segment 410. Specifically, the body of the sealing cylinder segment 410 can be configured as a rectangular parallelepiped. The sealing cylinder segment 410 is internally provided with at least one sealing element. This, together with the sealer 427 of the sealing assembly 420, forms a multi-sealing effect, significantly improving airtightness. As shown in Figure 8, in a preferred embodiment, the interior of the sealing cylinder segment 410 is sequentially provided with a first sealing element 415 and a second sealing element 416 along the direction from the pipe inlet 412 toward the pipe outlet. The first sealing element 415 comprises a pair of sealing rollers with adjustable spacing. A sealing curtain is connected between the sealing rollers and the inner wall of the sealing cylinder segment 410. The second sealing element 416 comprises a pair of inflatable third expansion elements. The third expansion body can expand by being inflated to form an inward squeeze, that is, the third expansion body is in closer contact with the hose after the volume increases.

[0074] As shown in Figures 6 and 7 , the pressurizing section preferably includes a cylindrical section 430 and a conical section 440. The cylindrical section 430 and the conical section 440 are connected at their larger ends by fasteners or are integrally formed. The conical section 440 has the aforementioned outlet at its smaller end. In a preferred embodiment, the tilting machine 400 includes a body, a base, and an adjustment mechanism. The body includes the aforementioned sealing section 410, the pressurizing section, and the sealing assembly 420. The base is provided with a fixing hole 470 for connecting to the aforementioned first and second mounting seats. The adjustment mechanism connects the body and base of the tilting machine 400 to adjust their relative position. The adjustment mechanism includes a handwheel 450 and a lifting rod connected to the handwheel 450. The lifting rod is connected to the body. A worker can raise or lower the lifting rod by turning the handwheel 450, thereby changing the distance between the body and base of the tilting machine 400. Further preferably, the sealing cylinder segment 410 and the pressurizing cylinder segment are each connected to an adjusting mechanism, and the sealing cylinder segment 410 and the pressurizing cylinder segment are respectively hinged to the upper end of the lifting rod. By operating the handwheels 450 of these two adjusting mechanisms, the pitch angle of the fuselage relative to the base can be adjusted, so that the flip machine 400 can better adapt to the requirements of the construction site for the fuselage angle.

[0075] In a preferred embodiment, the control panel 460 of the turning machine 400 is arranged on the top of the sealing cylinder section 410. Specifically, a base that can rotate horizontally can be set on the top of the sealing cylinder section 410, and the control panel 460 is set at a certain angle to the base. As shown in Figure 6, the lower end of the control panel 460 is hinged to the base, and the back of the control panel 460 is connected to the base through an adjustable length diagonal brace device. With this arrangement, the control panel 460 can be adjusted by rotating up and down and twisting left and right, thereby making it easier for staff to operate components such as switches on the front of the control panel 460. As shown in Figure 13, in this embodiment, the control panel 460 is provided with a display 461, a wiring hole 462, a main air intake valve 463 and several control switches, wherein the main air intake valve 463 is connected to the air pump 500 through a pipeline, the first control switch 464 is the total air intake pressure control switch, and the other control switches are pressure control switches for each air branch. For example, the second control switch 465 is connected to the fifth pressurization hole 432 provided in the pressurization cylinder segment through a pipeline to provide the internal pressure of the pressurization cylinder segment; the third control switch 466 and the fourth control switch 467 are respectively connected to the first pressurization hole 417 and the second pressurization hole 418 of the second sealing body 416 through pipelines; the fifth control switch 468 and the sixth control switch 469 are respectively connected to the third pressurization hole 421 and the fourth pressurization hole 422 of the sealing assembly 420 through pipelines to provide expansion pressure for the second expansion body 428. The seventh control switch 4610 is connected to the sixth pressurizing hole 441 fixed on the pressurizing cylinder segment through a pipeline to provide expansion pressure for the first expansion body 442 . As shown in FIG. 8 , the first expansion body 442 is connected to the sixth pressurizing hole 441 through a pipeline.

[0076] The cable collection hole 462 provides an installation channel for cables connecting the control panel 460 and external devices. Specifically, the cables pass through the cable collection hole 462, enter the control panel 460, and are electrically connected to the control panel 460's circuit board. For example, the turning machine 400 is equipped with several pressure sensors, and the cables connecting these pressure sensors to the control panel 460 pass through the cable collection hole 462. As shown in Figures 6 to 12, in this embodiment, the first pressure sensor 413 and the second pressure sensor 414 are used to detect the internal pressure of the first sealing body 415, the third pressure sensor 423 and the fourth pressure sensor 424 are used to detect the internal pressure of the second expansion body 428, and the fifth pressure sensor 433 is used to detect the internal pressure of the pressurized cylinder segment. The internal pressure of the pressurized cylinder segment is used to realize the flipping and propulsion of the hose, that is, the internal pressure of the pressurized cylinder segment provides the air pressure power required for the flipping of the hose. Therefore, the internal pressure of the pressurized cylinder segment is usually relatively high. In order to further ensure the safety of the equipment, the pressurized cylinder segment is generally provided with an anti-expansion hole 431. As shown in Figure 6, the anti-expansion hole 431 is in a normally closed state. When the internal pressure of the pressurized cylinder segment reaches a certain threshold, the anti-expansion hole 431 opens to relieve pressure.

[0077] As shown in Figures 14 and 15 , in a preferred embodiment, the support body of the mobile support 140 includes a lifting mechanism 143 for adjusting the vertical distance between the second mounting base and the wheels 142. The height of the second mounting base can be adjusted via this lifting mechanism 143. Specifically, this lifting mechanism 143 can be configured as a scissor-type lifting mechanism 143. As shown in Figure 15 , the bottom of the second mounting base is provided with multiple positioning slots 144. When the lifting mechanism 143 is engaged in different positioning slots 144, the angle between the two scissor arms varies, thereby changing the overall height of the lifting mechanism 143. Further preferably, the mobile bracket 140 can be provided with wheels 142 only on one side of the bracket body, and foot pads on the opposite side. For example, in the present embodiment, the wheels 142 are only provided on the side of the bracket body close to the pusher. In this way, the staff can first apply a force to the pusher to rotate around the wheels 142 to make the foot pad on the other side leave the ground, and then apply a forward or backward force to the pusher to move the mobile bracket 140. When the mobile bracket 140 moves to the target position, the foot pad side of the bracket body is lowered to make the foot pad contact with the ground, and the friction between the foot pad and the ground is used to better maintain the mobile bracket 140 at the target position.

[0078] As shown in Figures 14 and 15, in a preferred embodiment, the push handle of the mobile bracket 140 includes a telescopic arm 146 with adjustable length. This makes it easier for workers of different heights to operate the mobile bracket 140, and the mobile bracket 140 can be stored to reduce its volume. Two unpowered rollers 141 can be set in parallel on the push handle of the mobile bracket 140 to guide and level the hose. That is, in State II, the hose 802 first passes between the two unpowered rollers 141 and then passes into the turning machine 400. As shown in Figures 7 and 15, in this embodiment, the bracket body is connected to the fixed mounting hole 470 on the base of the turning machine 400 via a fixing rod 145, thereby mounting the turning machine 400 on the mobile bracket 140.

[0079] As shown in Figures 1 and 2, in a preferred embodiment, a mobile rack storage cabinet 102 is installed within the vehicle compartment. The mobile rack 140 can be stored in the mobile rack storage cabinet 102 when not in use. To better utilize the space within the vehicle compartment, the mobile rack storage cabinet 102 can be configured as a wall-mounted cabinet. In this embodiment, a dry hose material cabinet 104 provides a dry hose material storage area. Dry hoses 800 waiting to be used are placed in the dry hose material cabinet 104 for quick access by staff. The dry hose material cabinet 104 is preferably configured as a wall-mounted cabinet to maximize space utilization within the vehicle compartment. The base material storage area and the guide sleeve storage area can be located directly on the vehicle compartment floor. For example, multiple barrels of base material 900 can be placed in rows along the side walls of the vehicle compartment. Furthermore, the guide sleeves 110 are typically made of flexible plastic tubes, making them foldable and retractable. Based on this feature, a guide sleeve material cabinet similar to the dry hose material cabinet 104 or the mobile rack storage cabinet 102 can be installed within the vehicle compartment to provide a guide sleeve storage area. The vehicle-mounted support frame 101 is preferably configured as a posture-adjustable support frame. For example, the vehicle-mounted support frame 101 has at least one of the following adjustment functions: it can be extended horizontally, raised and lowered in height, and rotated horizontally within a certain angle range (such as 90°, 180°, 360°, etc.).

[0080] Further preferably, the vehicle compartment is equipped with at least one of the following: lighting equipment 103 for providing sufficient light; a constant temperature control system 105 for maintaining a constant temperature environment within the vehicle compartment; and a tool cabinet 107 for storing tools needed during construction. The substrate generally requires a low temperature during use, and the constant temperature control system 105 can better meet the substrate's performance requirements.

[0081] In this specification, the structure of each part is described in a progressive manner, and the structure of each part focuses on the differences from the existing structure. The overall and partial structures of the flip lining repair equipment can be obtained by combining the structures of the above multiple parts.

[0082] Based on the inversion lining repair equipment provided by the present invention, the present invention also provides an inversion lining repair method for pipeline repair and reinforcement, which specifically includes the following steps:

[0083] S1: Drive the work vehicle 100 to the construction site and stop it, with the rear of the vehicle facing the working well 120 on the ground, and install the turning machine 400 on the vehicle support frame 101 or the mobile bracket 140;

[0084] S2: Take the required matrix from the matrix material storage area and place it into the matrix mixing device 200 for uniform mixing;

[0085] S3: A dry hose 800 is taken from the dry hose material storage area and laid in the hose dipping and flattening device 300. The matrix is ​​injected into the dry hose 800 through the discharge hole 202 of the matrix mixing device 200, and the dry hose 800 is rolled by the roller group of the hose dipping and flattening device 300 to obtain a hose to be used;

[0086] S4: Pass one end of the unused hose through the turning machine 400 and then turn it over and fix it on the outlet side of the turning machine 400;

[0087] S5: Take the guide sleeve 110 from the guide sleeve storage area, place one end of the guide sleeve 110 into the working well 120 and align it with the pipeline to be repaired 130, and align the other end with the outlet side of the turning machine 400;

[0088] S6: Start the air pump 500 to push the standby hose forward through air power, and the standby hose enters the pipeline to be repaired 130 through the guide sleeve 110.

[0089] As shown in Figures 3 and 16 , when construction site space permits, the work vehicle 100 can be parked directly at the work pit 120, with the turning machine 400 mounted on the vehicle-mounted support frame 101. If construction site space is limited and the work vehicle 100 cannot reach the work pit 120, the turning machine 400 can be mounted on a mobile support 140, which can then be pushed to the work pit 120. The configuration of the mobile support 140 improves the adaptability of the turning lining repair equipment to various environmental conditions.

[0090] The ready-to-use hose obtained in step S3 is State II hose 802 in Figure 1. State II hose 802 is flipped after turning machine 400 and, under the action of air pressure, advances along guide sleeve 110, ultimately entering pipeline 130 to be repaired. After the hose is flipped, the matrix impregnated within the hose is positioned on its outer surface, thereby bonding and securing it to the inner wall of pipeline 130 to be repaired. State IV hose 804 is securely connected to pipeline 130 via the matrix. To facilitate reuse of guide sleeve 110, it is typically made of a special plastic, such as tetrafluoroethylene, to prevent bonding to the matrix. State III hose 803, therefore, does not bond to guide sleeve 110. It should be noted that in the final stage of pipeline repair and reinforcement, State III hose 803 should be separated from State IV hose 804.

[0091] In a preferred embodiment, the step S2 includes: vacuuming the matrix mixing device 200 during the mixing process to remove gas from the matrix after mixing. The step S3 includes: continuously extracting gas from the hose by negative pressure suction during the rolling process.
