Description

Technical Field

[0001] This invention relates to the field of trenchless pipeline repair construction technology, and in particular to an auxiliary device for trenchless pipeline lining repair construction and its usage method. Background Technology

[0002] In the construction of stainless steel lining for trenchless pipeline repair, stainless steel segments need to be transported in from the outside, and then assembled into rings inside the pipeline to form a stainless steel lining. Finally, grouting is performed behind the wall to make the lining segment and the original pipeline form a composite whole, thereby achieving the purpose of pipeline repair.

[0003] However, in actual construction, the presence of a central guide pipe for temporary drainage within the pipeline results in a confined internal space. This central guide pipe can easily interfere with the transportation, splicing, and installation of the inner lining segments. Furthermore, the large size and weight of the inner lining segments make their transportation, splicing, and installation extremely difficult. Therefore, there is a need to provide an auxiliary device and its usage method for trenchless pipeline lining repair construction, which can solve the problems of difficult transportation and splicing of inner lining segments in existing technologies.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. The present invention is equipped with a transport track and a transport component. The transport component can move along a pair of tracks via a first track wheel for transporting inner liner segments above the central guide tube. The transport component can also raise and lower the inner liner segments via a lifting mechanism. During transport, the inner liner segments are lowered, and after being transported to the designated position, the inner liner segments are raised to the designated height. This ensures the safe transport and splicing of the inner liner segments in a confined space, avoids interference of the central guide tube with the transport of the inner liner segments, and makes the transport easier and more efficient.

[0042] 2. Because the present invention is equipped with a transport track and splicing components, the inner lining tube segments can be rotated to a position that is easy to weld by rotating the tube segment rotating disk through the rotation drive mechanism. This facilitates the welding and splicing of the inner lining tube segments in the narrow space above the central guide tube, avoids overhead welding, reduces welding difficulty, improves welding quality and welding efficiency, and requires less space for splicing, thus solving the problem of difficult splicing of inner lining tube segments.

[0043] 3. Because the present invention is equipped with a transport track and a splicing component, the splicing component can move synchronously along a pair of tracks during the installation process of the repair lining ring through the second track wheel, which facilitates the installation of the repair lining ring at the part of the pipeline to be repaired, facilitates the pipeline repair construction, reduces the construction space requirements for the installation of the repair lining ring, and thus reduces the construction difficulty of repairing the pipeline lining steel plate.

Detailed Implementation

[0059] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the auxiliary device and its method for trenchless pipeline lining repair construction proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0060] Please see the appendix Figure 1 Appendix Figure 13 To be continued Figure 15 An auxiliary device for trenchless pipeline lining repair construction includes a transport track 1, a transport component 2, and a splicing component 3. The transport track 1 is arranged parallel to the axial direction of the pipeline 6 and is located on top of the intermediate guide tube 5. The transport component 2 is movably mounted on the transport track 1, and the lining segments 4 are placed on the transport component 2 and move synchronously with the transport component 2. The splicing component 3 is movably mounted on the transport track 1 and can clamp the lining segments 4, so that several lining segments 4 are connected on the splicing component 3 to form a repair lining ring 400, which is then installed at the repair location of the pipeline 6.

[0061] The transport track 1 is used to guide and limit the movement of the transport assembly 2 and the splicing assembly 3, thereby ensuring the stable transport of the inner liner segment 4 between the intermediate guide tube 5 and the pipeline 6. The transport assembly 2 is used to carry the inner liner segment 4. After the inner liner segment 4 is hoisted into the well, it is placed on the transport assembly 2, and then transported to the splicing assembly 3 via the transport assembly 2. The splicing assembly 3 is positioned close to the location of the pipeline 6 to be repaired, and is used to weld and splice several inner liner segments 4 to form a repair inner liner ring 400, thereby facilitating the installation of the spliced ​​repair inner liner ring 400 to the location of the pipeline 6 to be repaired.

[0062] By setting up the transport component 2, the problem of inconvenient transport of the inner lining segment 4 due to the narrow space between the middle guide tube 5 and the pipe 6 is solved; by using the splicing component 3 to temporarily fix and rotate the inner lining segment 4, the welding and splicing operations of adjacent inner lining segments 4 are facilitated, and the problem of difficult splicing of the inner lining segment 4 in a narrow space is solved.

[0063] Please see the appendix Figure 2 The transport track 1 includes guide rails 101 and supports 102; a pair of guide rails 101 are parallel to each other and are arranged along the axial direction of the pipe 6; several supports 102 are spaced apart along the axial direction of the pipe 6 at the top of the intermediate guide tube 5; the pair of guide rails 101 are installed on the top of the intermediate guide tube 5 through several supports 102; the transport component 2 and the splicing component 3 are movably arranged on the pair of guide rails 101.

[0064] Preferably, the support 102 can adopt a U-shaped structure, and the bottom of the support 102 is an arc-shaped structure that matches the outer diameter of the middle guide tube 5, so that the support 102 fits against the top surface of the middle guide tube 5 through the arc-shaped structure, with a large contact area and high installation stability, so as to ensure the stability of the installation and use of the transport component 2 and the splicing component 3 on the transport track 1.

[0065] Preferably, the guide rail 101 can adopt a T-shaped or other structural form according to actual usage requirements. The top two ends of the support 102 are used to support a pair of guide rails 101 respectively. The number of supports 102 can be adjusted according to the load-bearing requirements to ensure load-bearing safety.

[0066] Please see the appendix Figure 3 To be continued Figure 5 The transport component 2 includes a first track wheel 201, a lifting mechanism, a segment support plate 204, and a first frame 205; a plurality of first track wheels 201 are installed in pairs on both sides of the first frame 205, and a plurality of first track wheels 201 are rolled on a pair of guide rails 101; the segment support plate 204 is liftably mounted on the first frame 205 via the lifting mechanism, and the inner lining segment 4 is placed on the segment support plate 204.

[0067] Preferably, four first track wheels 201 are provided on both sides of the first frame 205. The four first track wheels 201 cooperate with a pair of guide rails 101 to realize the movement of the first frame 205 along the pair of guide rails 101.

[0068] Preferably, the segment support plate 204 has an arc-shaped structure that matches the inner lining segment 4, allowing the inner lining segment 4 to fit snugly on the segment support plate 204. Through surface contact, the inner lining segment 4 can be stably placed on the segment support plate 204 and move synchronously with the transport assembly 2. The lifting mechanism controls the height of the segment support plate 204, thereby controlling the height of the inner lining segment 4. The inner lining segment 4 is positioned at a certain height above the central guide tube 5, preventing interference from the central guide tube 5 and other components during transport. After being transported to its designated position, the mechanism lifts the inner lining segment 4, allowing the splicing assembly 3 to temporarily clamp and fix it.

[0069] Please see the appendix Figure 3 The lifting mechanism includes a push-pull rod 202 and a lifting rod 203; the push-pull rod 202 is an X-shaped rotating and folding structure, and a pair of push-pull rods 202 are symmetrically arranged on both sides of the first frame 205, and the segment support plate 204 is arranged on the top of the pair of push-pull rods 202; a pair of lifting rods 203 are respectively connected between the pair of push-pull rods 202 and the first frame 205.

[0070] Preferably, the lifting rod 203 can be a hydraulic lifting rod, such as a jack, and the appropriate specification of the hydraulic lifting rod can be selected according to the weight of the inner lining segment 4. A pair of lifting rods 203 are started synchronously to ensure the smooth lifting and lowering of the segment support plate 204, thereby ensuring that the inner lining segment 4 is stably lifted to the splicing assembly 3.

[0071] Please see the appendix Figure 6 To be continued Figure 9 The splicing assembly 3 includes a rotation drive mechanism, a segment rotating disk 303, segment clamps 306, a support mechanism, second track wheels 309, and a second frame 310. Several second track wheels 309 are installed in pairs on both sides of the second frame 310, and several second track wheels 309 are rolled on a pair of guide rails 101. The segment rotating disk 303 is arranged around the outer periphery of the central guide tube 5. The rotation drive mechanism is installed on the second frame 310 and is connected to the segment rotating disk 303 for transmission. Several segment clamps 306 are respectively spaced on the segment rotating disk 303, and the inner liner segments 4 are clamped by the segment clamps 306. A pair of support mechanisms are symmetrically arranged on both sides of the second frame 310, and each set of support mechanisms is supported between the central guide tube 5 and the segment rotating disk 303.

[0072] Preferably, the segment clamps 306 are positioned at 90° intervals on the segment rotating disk 303 to clamp four inner liner segments 4, allowing the four inner liner segments 4 to be spliced ​​together to form a repair inner liner ring 400. A rotation drive mechanism drives the segment rotating disk 303 to rotate, thereby rotating the inner liner segments 4 to a position conducive to welding. This minimizes the impact of limited space on the splicing operation of the inner liner segments 4, while also avoiding overhead welding operations, thus ensuring welding quality and efficiency.

[0073] Preferably, the outer diameter of the segment rotating disk 303 is slightly smaller than the inner diameter of the repair liner ring 400, so that after the liner segments 4 held by the four segment clamps 306 are spliced ​​into the repair liner ring 400, the diameter of the repair liner ring 400 meets the repair requirements of the pipeline 6.

[0074] Preferably, four second track wheels 309 are provided on both sides of the second frame 310. The four second track wheels 309 cooperate with a pair of guide rails 101 to realize the movement of the second frame 310 along the pair of guide rails 101. The second frame 310 moves synchronously with the installation process of the repair liner ring 400.

[0075] The segment clamp 306 is used to temporarily clamp and fix the inner liner segment 4, so that the inner liner segment 4 is fixed on the segment rotating disk 303 and rotates synchronously with it. The support mechanism is used to support the segment rotating disk 303, transfer the weight of the segment rotating disk 303 and the weight of the inner liner segment 4 clamped on it to the middle guide tube 5, and ensure the splicing stability of the inner liner segment 4.

[0076] Please see the appendix Figure 6 To be continued Figure 9 The rotation drive mechanism includes a drive component 301, a drive gear 302, and a control and power input element 308. The drive component 301 is mounted on the second frame 310, and the drive component 301 is connected to an external power supply and control system through the control and power input element 308. The drive gear 302 is coaxially mounted on the output shaft of the drive component 301, and a gear ring 311 is formed on the inner wall of the segment rotating disk 303, so that the drive gear 302 is meshed and connected to the segment rotating disk 303 through the gear ring 311.

[0077] Preferably, the drive unit 301 can be a motor with forward and reverse rotation functions. The motor power can be selected according to the weight of the inner lining segment 4 to ensure that the segment rotating disk 303 and the inner lining segment 4 / repair inner lining ring 400 can rotate stably during splicing and installation operations.

[0078] The output shaft of the motor can be connected to the drive gear 302 via a coupling. The motor controls the drive gear 302 to rotate forward or backward, thereby driving the segment rotating disk 303 and the inner lining segment 4 to rotate to a suitable welding position through the meshing of the drive gear 302 with the gear ring 311, or driving the segment rotating disk 303 and the repair inner lining ring 400 to rotate to a suitable installation position.

[0079] Please see the appendix Figure 6 To be continued Figure 9 Each set of support mechanisms includes a side wing leg 304, a support pulley 305, and a support rod 312; one end of the side wing leg 304 is connected to the side of the second frame 310, and the other end of the side wing leg 304 is connected to the support rod 312; one end of the support rod 312 abuts against the outer wall of the central guide tube 5, and the other end of the support rod 312 is rotatably mounted on the axis of the support pulley 305 through a rotating bearing, and the support pulley 305 rolls against the inner wall of the segment rotating disk 303.

[0080] Preferably, the side outrigger 304 can adopt an arc-shaped structure to avoid collision with the central guide tube 5. At the same time, the side outrigger 304 and the second frame 310 can be detachably or rotatably connected. When the second frame 310 moves, the support mechanism is not installed or the support mechanism is rotated upward to prevent wear between the support link 312 and the central guide tube 5. When splicing the inner liner segment 4 and installing the repair inner liner ring 400, the support mechanism is installed or rotated downward to abut against the central guide tube 5 to provide reliable support on both sides for the segment rotating disk 303, the inner liner segment 4 and the repair inner liner ring 400, ensuring the stability and safety of the construction process.

[0081] By setting up the support link 312, the weight of the segment rotating disk 303 and the inner lining segment 4 is transferred to the middle guide tube 5. A pair of support mechanisms and the drive gear 302 form three support points. The three support points distributed in an isosceles triangle can maximize the stability of the segment rotating disk 303, the inner lining segment 4 and the repair inner lining ring 400 and avoid instability.

[0082] By setting up the support pulley 305, the support pulley 305 rolls into contact with the inner wall of the segment rotating disk 303, resulting in low friction and reducing frictional resistance while ensuring stable support.

[0083] Please see the appendix Figure 6 To be continued Figure 9 The segment rotating disk 303 is an open annular structure, and a connecting rod 307 is detachably installed at the opening of the segment rotating disk 303, so that the segment rotating disk 303 and the connecting rod 307 form a closed loop structure.

[0084] The opening width of the segment rotating disk 303 is not less than the outer diameter of the intermediate guide tube 5, so as to facilitate the fitting of the segment rotating disk 303 to the outer circumference of the intermediate guide tube 5. After installation, the opening of the segment rotating disk 303 is closed by the connecting rod 307 to form a closed-loop structure, thereby improving the integrity and load-bearing capacity of the closed-loop structure.

[0085] Preferably, the segment rotating disk 303 is slightly larger than 3 / 4 of the ring to ensure that the four segment clamps 306 are arranged at equal intervals of 90° on the segment rotating disk 303, and the connecting rod 307 is slightly smaller than 1 / 4 of the ring.

[0086] Please see the appendix Figure 1 To be continued Figure 16 A method for using an auxiliary device for trenchless pipeline lining repair construction includes the following steps:

[0087] Step 1: Install transport track 1 parallel to the pipeline axis along the entire length of the pipeline. Transport track 1 is installed on the top of the middle guide tube 5.

[0088] Specifically, several brackets 102 are fixedly installed on the top of the central guide tube 5 along the axial direction of the central guide tube 5, and a pair of guide rails 101 are installed on the several brackets 102, with the pair of guide rails 101 arranged parallel to each other.

[0089] The support 102 can be installed on the central guide tube 5 by welding, screwing, or other methods, as long as the installation is stable and the load-bearing capacity is safe.

[0090] Please see the appendix Figure 9 Step 2: Place the splicing component 3 on the transport track 1 and slide it along the transport track 1 to the splicing position of the inner lining segment 4.

[0091] The splicing position of the inner lining segment 4 is located next to the installation position of the repair inner lining ring segment 400, so that after the repair inner lining ring segment 400 is spliced, it can be directly installed into the position inside the pipe 6 that needs to be repaired.

[0092] Step 2 includes the following sub-steps:

[0093] Step 2.1: The second frame 310 of the splicing component 3 is placed on a pair of guide rails 101 via a number of second track wheels 309.

[0094] Step 2.2: Disassemble the connecting rod 307 and fit the segment rotating disk 303 onto the outer periphery of the middle guide tube 5. The segment rotating disk 303 is engaged with the drive gear 302.

[0095] At this time, the weight of the segment rotating disk 303 is supported by the drive gear 302 and transmitted to the top of the intermediate guide tube 5.

[0096] Step 2.3: Install the connecting rod 307 to the opening of the segment rotating disk 303, so that the connecting rod 307 and the segment rotating disk 303 form a closed loop structure.

[0097] When rotating the segment rotating disk 303, prevent the segment rotating disk 303 from disengaging from the drive gear 302. Since the connecting rod 307 occupies a small size in the closed-loop structure, it can ensure that the welding positions of the four inner lining segments 4 are all rotated to the top of the middle guide tube 5, thereby facilitating the welding and splicing operation of the inner lining segments 4.

[0098] Step 2.4: The splicing assembly 3 is moved as a whole along a pair of guide rails 101 by several second track wheels 309 to the splicing position of the inner lining segment 4.

[0099] Step 2.5: Place one end of the support connecting rod 312 of the pair of support mechanisms against the outer walls of the two sides of the middle guide tube 5, and place the support pulleys 305 of the pair of support mechanisms against the inner walls of the segment rotating disk 303.

[0100] With a pair of support mechanisms set on both sides of the second car body 310, the support connecting rod 312 is supported on the central guide tube 5, and the support pulley 305 abuts against the inner wall of the segment rotating disk 303 to prevent the segment rotating disk 303 from swaying left and right, thereby ensuring the stability of the subsequent splicing of the inner lining segment 4.

[0101] Step 3: Place the transport component 2 on the transport track 1, place the inner lining tube 4 on the transport component 2, and transport it along the transport track 1 to the splicing component 3 via the transport component 2.

[0102] Specifically, the first frame 205 is placed on a pair of guide rails 101 via several first track wheels 201, and then an inner lining tube 4 is attached to the tube lining support plate 204. The transport component 2 and the inner lining tube 4 are moved together along the transport track 1 via the first track wheels 201 to the splicing component 3.

[0103] When transporting the inner liner segment 4, the push-pull rod 202 of the transport component 2 is folded, thereby reducing the height and center of gravity of the inner liner segment 4. This ensures the transport stability of the inner liner segment 4 and avoids collisions between the inner liner segment 4 and equipment or components inside the pipe 6, thus improving the transport safety of the inner liner segment 4. At the same time, it also reduces the transport space requirement between the pipe 6 and the intermediate guide tube 5.

[0104] Please see the appendix Figure 10 Step 4: Temporarily fix the inner lining segment 4 with the splicing component 3, and rotate the inner lining segment 4 to the welding position.

[0105] Preferably, the welding position can be located at the top of the middle guide tube 5. The splicing end of the inner liner segment 4 is rotated to the top of the middle guide tube 5, which makes it easier for construction personnel to set up a welding operation platform on the top of the middle guide tube 5 for welding adjacent inner liner segments 4, avoiding overhead welding operation, and helping to ensure welding quality and welding efficiency.

[0106] Step 4 includes the following sub-steps:

[0107] Step 4.1: The lifting rod 203 pushes the push-pull rod 202, so that the pair of push-pull rods 202 lift the segment support plate 204 to the height of the segment clamp 306.

[0108] To avoid collisions, the transport height of the inner liner segment 4 is relatively low. After being transported to its position, it is necessary to provide power through the lifting rod 203 to unfold the X-shaped push-pull rod 202. The push-pull rod 202 can adopt the existing technology of scissor bracing to lift the inner liner segment 4 to the height of the segment clamp 306 through the segment support plate 204, so as to ensure that the segment clamp 306 can reliably clamp the inner liner segment 4.

[0109] Step 4.2: Temporarily fix the inner lining segment 4 using segment clamp 306.

[0110] The segment clamp 306 can adopt a conventional segment clamping structure to stably clamp the inner liner segment 4. Preferably, one inner liner segment 4 can be clamped and fixed by one segment clamp 306. If the inner liner segment 4 is large in size or heavy in weight, the number of segment clamps 306 can be increased.

[0111] Step 4.3: The control and power input element 308 controls the start of the drive unit 301, so that the drive unit 301 drives the drive gear 302 to rotate.

[0112] The power supply provides working power to the drive unit 301 through the control and power input element 308. The control system controls the rotation direction and speed of the motor through the control and power input element 308, so that the drive gear 302 drives the segment rotating disk 303 in a specified direction and speed.

[0113] Step 4.4: The drive gear 302 meshes with the gear ring 311 to drive the segment rotating disk 303, so that the segment rotating disk 303 drives the inner liner segment 4 to rotate to the welding position through the segment clamp 306.

[0114] The drive gear 302 meshes with the gear ring 311, which provides high transmission stability and prevents slippage and loosening, ensuring stable rotation of the inner liner tube 4 and preventing it from wobbling behind the inner liner tube 4 due to the shift of the center of gravity.

[0115] Please see the appendix Figure 11 To be continued Figure 14Step 5: Weld two adjacent inner lining tube pieces 4, so that several inner lining tube pieces 4 are spliced ​​on the splicing assembly 3 to form a repair inner lining ring piece 400.

[0116] The inner lining segments 4 are spliced ​​together using conventional welding methods to form the repair inner lining ring segments 400, which will not be described in detail here.

[0117] Step 5 includes the following sub-steps:

[0118] Step 5.1: Transport component 2 returns, repeat steps 3 and 4, and transport the next inner liner segment 401 to the splicing component 3.

[0119] The transportation method of the inner lining segment 401 via the transport component 2 is the same as in step 3, and will not be repeated here. The transport component 2 transports the inner lining segment 4 back and forth, forming a streamlined collaborative operation with the splicing component 3, which reduces the difficulty of transporting and assembling the inner lining segment 4 and improves construction efficiency.

[0120] Step 5.2: Temporarily fix the next inner lining segment 401 with segment clamp 306, and make the next inner lining segment 401 adjacent to the inner lining segment 4 to facilitate welding and splicing.

[0121] Step 5.3: Weld and fix the next inner lining segment 401 to the inner lining segment 4, as shown in the attached figure. Figure 11 As shown.

[0122] Step 5.4: Repeat steps 5.1 to 5.3, sequentially transporting and welding several inner lining segments 4 to form a repaired inner lining ring 400, as shown in the attached figure. Figure 12 To be continued Figure 14 As shown.

[0123] Please see the appendix Figure 15 Step 6: Replace the support in the middle guide tube 5 and install the repair liner ring 400 to the part of the pipe 6 to be repaired.

[0124] Specifically, support columns 501 are provided between the bottom two sides of the intermediate conduit 5 and the inner wall of the pipe 6, as shown in the attached figure. Figure 16 As shown, replacement support columns (not shown in the figure) are set between the bottom two sides of the middle guide tube 5 and the inner wall of the installed repair liner ring 400, and the support column 501 at the repair liner ring 400 to be installed is removed. The repair liner ring 400 is then installed at the installation position and connected to the installed repair liner ring 400 as a whole.

[0125] Since the weight of the entire auxiliary device and the repair liner ring 400 needs to be borne by the central guide tube 5, the support columns 501 are set between the bottom sides of the central guide tube 5 and the inner wall of the pipe 6 to improve the stability of the central guide tube 5 and thus ensure the safety of construction.

[0126] However, the support column 501 interferes with the movement and installation of the repair liner ring 400. Therefore, it is necessary to replace the support first, and then install the repair liner ring 400 while ensuring safety. During the support replacement, the support column 501 that interferes with the installation of the repair liner ring 400 is first removed, and a replacement support column is installed between the already installed repair liner ring 400 and the middle guide tube 5. This replacement support column will not interfere with the subsequent installation of the repair liner ring 400, thus ensuring the construction safety of the repair liner ring 400 to be installed.

[0127] Step 7: Release the temporary clamping of the splicing component 3 on the repair liner ring 400, and move the splicing component 3 to the next welding position.

[0128] Step 8: Repeat steps 2 through 7 until pipe 6 is repaired.

[0129] When installing the repair lining rings 400 in sequence, adjacent repair lining rings 400 can be connected by staggered joints to improve the structural strength of the entire repair lining.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
