Description

Technical Field

[0001] The present invention relates to a flexible composite pipeline repair device, belonging to the technical field of pipeline repair. Background Art

[0002] Due to advantages such as light weight, corrosion resistance, and fatigue resistance, flexible composite pipelines are widely used in fields such as oil and gas transportation, chemical industry, municipal water supply and drainage, etc. However, during long-term use of flexible composite pipelines, due to factors such as mechanical damage, chemical corrosion, and aging, the pipelines may have certain leaks, which will affect the safety and service life of the pipelines to a certain extent.

[0003] At present, for the damage repair of flexible composite pipelines, two main methods are mainly adopted, namely overall replacement and manual repair. Among them, overall replacement is mainly used for important main pipelines with large flow rates. Since the main pipelines undertake the important task of transporting fluids or gases, higher quality requirements are imposed on the pipelines. Usually, the leaking pipelines are dug out and replaced as a whole to ensure the long-term stable operation of the main pipelines.

[0004] Manual repair is mainly used for branch pipelines with small flow rates or for emergency use. Since the use frequency of branch pipelines is relatively low, they can be put back into use after manual repair, which can effectively reduce costs. However, since manual repair highly depends on the repair experience of repair personnel, there are problems such as low repair efficiency and unstable quality. Moreover, when repairing pipelines, due to the certain weight of the pipelines, multiple people are required to cooperate for operations such as flipping, and there is also the problem of high labor intensity.

[0005] For example, an oil and gas pipeline damage repair device disclosed in a Chinese utility model patent with the publication number CN220286791U includes a fixed bracket. The fixed bracket includes a top plate and a bottom plate. Four corners at the bottom of the top plate are fixedly connected with connecting rods, and the bottom ends of the four connecting rods extend into the interior of the top plate. A fastening component is arranged between the fixed bracket and the top plate, and a disassembly and assembly component is arranged inside the bottom plate. The disassembly and assembly component includes installation cavities opened on the left and right sides inside the bottom plate. A cam is arranged in the middle of the inner cavity of the installation cavity. The bottom end of the cam is rotatably connected with the inner wall of the installation cavity. Arc-shaped plates are arranged at the front and rear ends of the cam. One side of the two arc-shaped plates facing each other is in contact with the two ends of the cam. The top ends of the two cams are fixedly connected with L-shaped rotating rods, and the two L-shaped rotating rods extend to the outside of the bottom plate, which is convenient for operators to install and use and improves work efficiency.

[0006] The above reference example plugs leaks by squeezing the upper fastening plate and the lower fastening plate on the pipeline surface, and relies on the linkage adjustment of multiple components such as cams and L-shaped rotating rods to adjust the fastening pressure. The operation steps are cumbersome, and the requirements for personnel operation skills are high, which is time-consuming and laborious. Therefore, improvement is urgently needed.

[0047] The present invention will be described in more detail below in conjunction with embodiments.

[0048] Embodiment 1

[0049] Please refer to Figures 1 to 6 , the flexible composite pipeline repair device of this embodiment includes a support frame 200. There are two support frames 200 arranged at intervals in the horizontal direction. The pipe body 100 is rotatably installed between the two support frames 200. The support frame 200 plays a supporting role for the pipe body 100 and also allows the pipe body 100 to rotate, facilitating the subsequent application of repair glue.

[0050] In order to facilitate changing the position of the pipe body 100, driving slide rails 300 for driving the horizontal movement of the support frame 200 are arranged at the bottom ends of the two support frames 200. The driving slide rails 300 can be driven by a cylinder or by electricity, facilitating the subsequent repair of different positions of the pipe body 100.

[0051] Among them, a repair mechanism 400 is also arranged between the two support frames 200.

[0052] Specifically, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the repair mechanism 400 includes a liquid storage box 19, a repair plate 17 and a liquid brushing mechanism.

[0053] Among them, the liquid storage box 19 is provided with an open top, facilitating the brush bristles 18 at the bottom end of the repair plate 17 to enter the liquid storage box 19 to dip the repair glue.

[0054] The liquid storage box 19 stores repair glue for repairing the pipe body 100, and the repair glue is selected as epoxy resin glue.

[0055] A brush hair 18 is provided at the bottom end of the repair plate 17, and the brush liquid mechanism is used to periodically drive the brush hair 18 at the bottom end of the repair plate 17 to apply the repair glue to the surface of the pipe body 100.

[0056] Specifically, the brush liquid mechanism includes a base 1 and a driving device. A support assembly and a limiting assembly are vertically and fixedly installed at the top end of the base 1. The support assembly and the limiting assembly are arranged away from the pipe body 100 in sequence. The support assembly includes two support rods 2 arranged horizontally at intervals. Both of the two support rods 2 are arranged directly below the pipe body 100. The limiting assembly includes two limiting rods 5 arranged horizontally at intervals.

[0057] Wherein, sliders 12 are rotatably installed at the top ends of the opposite sides of the two limiting rods 5. A pair of vertical rods 10 are fixedly connected to the top end of the repair plate 17. A sliding groove 11 is formed in the vertical rods 10 along the length direction. The sliders 12 are slidably clamped in the sliding grooves 11. A connecting rod transmission mechanism is hinged between one of the support rods 2 and one of the limiting rods 5 on the same side. One end of the connecting rod transmission mechanism is in transmission connection with the driving device, and the other end is hinged to the vertical rod 10. The driving device lifts the vertical rod 10 through the connecting rod transmission mechanism.

[0058] Specifically, the connecting rod transmission mechanism includes a first hinge rod 7, a second hinge rod 8, a third hinge rod 9, and a fourth hinge rod 1301. The connecting rod transmission mechanism further includes a transmission assembly vertically and fixedly installed at the top end of the base 1. The transmission assembly includes two transmission rods 4 arranged horizontally at intervals. The transmission rods 4 are arranged between the support rod 2 and the limiting rod 5. A driving rod 6 is rotatably penetrated and installed between the two transmission rods 4;

[0059] One end of the fourth hinge rod 1301 is fixedly sleeved with a transmission rod 13. The free end of the transmission rod 13 rotatably penetrates the support rod 2 and is in transmission connection with the driving device. The other end of the fourth hinge rod 1301 is hinged to one end of the first hinge rod 7. The other end of the first hinge rod 7 is hinged to one end of the second hinge rod 8. The other end of the second hinge rod 8 is fixedly sleeved with the end of the driving rod 6. One end of the third hinge rod 9 is fixedly sleeved with the driving rod 6. The other end of the third hinge rod 9 is hinged to the vertical rod 10.

[0060] Please refer to Figure 2 and Figure 3 , it can be seen from the above description that when the driving device is started, the driving device can drive the transmission rod 13 to rotate. The rotation of the transmission rod 13 can drive the fourth hinge rod 1301 to swing. When the fourth hinge rod 1301 swings, the free end of the fourth hinge rod 1301 can drive the first hinge rod 7 to move, and the free end of the first hinge rod 7 can push the second hinge rod 8 to swing downward.

[0061] Since the ends of the second hinged rod 8 and the driving rod 6 are fixedly connected, when the second hinged rod 8 swings downward, the driving rod 6 will rotate synchronously. Since one end of the third hinged rod 9 is fixedly connected to the driving rod 6, the driving rod 6 can drive the free end of the third hinged rod 9 to swing upward, so that the third hinged rod 9 can lift the vertical rod 10.

[0062] Since the free end of the third hinged rod 9 performs a circular swinging motion, when the vertical rod 10 is lifted, the vertical rod 10 gradually changes from being lifted upward to moving horizontally with the cooperation of the slide groove 11 and the slider 12, so that the bristles 18 at the bottom end of the repair plate 17 can be horizontally attached to the tube body 100, and the repair glue on the bristles 18 can be applied to the surface of the tube body 100 to repair the surface of the tube body 100.

[0063] At the same time, the liquid brushing mechanism is also used to periodically rotate the tube body 100 .

[0064] Specifically, the liquid brushing mechanism further includes an elastic sleeve ring 3 .

[0065] See also Figure 3 The elastic sleeve ring 3 is sleeved on the outside of the tube body 100, and the elastic sleeve ring 3 is movably clamped on the top of the support rod 2 close to the connecting rod transmission mechanism. Eight toggle grooves 301 are evenly opened along the circumferential direction on the outer edge of the elastic sleeve ring 3. The inner end of each toggle groove 301 is arranged toward the center of the elastic sleeve ring 3, and an arc groove 302 is also arranged between any two toggle grooves 301, and each arc groove 302 is evenly spaced along the circumferential direction.

[0066] The number of the toggle grooves 301 can be set according to the degree of damage of the tube body 100. If the damage of the tube body 100 is serious and there are many parts, the number of the toggle grooves 301 can be increased so that the tube body 100 can be rotated one circle and the number of glue repairs can be increased as much as possible.

[0067] See also Figure 4 A swing rod 14 is fixedly sleeved on the transmission rod 13, and the free end of the swing rod 14 is vertically arranged upward, and a toggle rod 15 is vertically fixedly sleeved on the free end of the swing rod 14, and the toggle rod 15 is movably clamped at the inner end of any one of the toggle grooves 301. In this embodiment, the toggle rod 15 and the toggle groove 301 are in a movably clamped relationship, mainly to use the toggle rod 15 to toggle the elastic sleeve ring 3 to rotate periodically. Every time a toggle groove 301 is toggled, the elastic sleeve ring 3 rotates a fixed angle, thereby driving the tube body 100 sleeved in the elastic sleeve ring 3 to rotate a fixed angle.

[0068] At the same time, the transmission rod 13 is also integrally provided with an arc block 16 adapted to the arc groove 302. The arc block 16 is arranged directly below the elastic sleeve ring 3, and the arc block 16 is arranged in the opposite direction to the swing rod 14. After the toggle rod 15 exits the toggle groove 301, the arc block 16 gradually fits with the arc groove 302 but does not contact it under the rotation of the transmission rod 13. Since the arc groove 302 and the arc block 16 are adapted to each other, the arc groove 302 can be limited during the rotation of the arc block 16, thereby preventing the elastic sleeve ring 3 from rotating due to external force, thereby ensuring the stability of the elastic sleeve ring 3.

[0069] When the repair position of the tube body 100 needs to be changed, the driving slide rail 300 can be controlled to drive the tube body 100 to move laterally. Since the elastic sleeve ring 3 is sleeved on the tube body 100 to drive the tube body 100 to rotate, in order to prevent the elastic sleeve ring 3 from changing position with the lateral movement of the tube body 100, the toggle rod 15 passes through the toggle groove 301 and is fixedly sleeved on the limit block 1501, and the diameter of the limit block 1501 is greater than the width of the toggle groove 301.

[0070] By setting the limit block 1501 , after the toggle rod 15 is inserted into the toggle groove 301 , the elastic sleeve ring 3 can be engaged by the limit block 1501 and the swing rod 14 to prevent it from moving with the lateral movement of the tube body 100 .

[0071] In this embodiment, the inner ring of the elastic sleeve ring 3 is an elastic ring, which clamps the tube body 100 to facilitate the rotation of the tube body 100. The outer ring of the elastic sleeve ring 3 is a metal ring, which is convenient for engaging with the limit block 1501 and the swing rod 14.

[0072] A support ring 201 is fixedly connected to the top of the other support rod 2 , and the support ring 201 is rotatably sleeved outside the tube body 100 .

[0073] Embodiment 2

[0074] See also Figures 6 to 10 The flexible composite pipeline repairing device of this embodiment is based on the above-mentioned embodiment 1. Three liquid spraying pipes 20 are connected to the side of the liquid storage box 19 away from the pipe body 100, and the free end of each liquid spraying pipe 20 is connected to a liquid spraying mechanism.

[0075] Among them, the liquid spraying mechanism includes a base plate 2102, on which an extrusion cylinder 21 and an extrusion mechanism 23 are installed. The extrusion cylinder 21 is connected to a liquid inlet pipe 22, and the free end of the liquid inlet pipe 22 is connected to the raw material end providing the repair glue. The raw material end transports the repair glue to the extrusion cylinder 21 through the liquid inlet pipe 22 by pumping. A one-way valve is installed in the liquid inlet pipe 22 and each liquid spraying pipe 20. The setting of the one-way valve can prevent the repair glue from flowing back.

[0076] The repair glue in the liquid storage box 19 can be replenished at any time by the provision of the liquid spraying mechanism.

[0077] Specifically, an extrusion piston 24 and an extrusion piston 25 are connected inside the extrusion cylinder 21 in a sliding and sealing manner, and the extrusion piston 24 and the extrusion piston 25 are respectively arranged on both sides of the connecting hole between the spray pipe 20 and the extrusion cylinder 21, and the extrusion mechanism 23 is used to drive the extrusion piston 24 and the extrusion piston 25 to move relative to each other.

[0078] Through the relative movement of extrusion piston 1 24 and extrusion piston 2 25, the repair glue in the extrusion cylinder 21 can be sprayed into the liquid storage box 19 by compressed injection, so that the repair glue sprayed into the liquid storage box 19 can spray the bristles 18, which can not only assist the bristles 18 to adhere to the repair glue, but also can spray off the residue or oxidized waste left after the bristles 18 are applied to the tube body 100, thereby preventing the impurities remaining on the bristles 18 from affecting the repair of the tube body 100.

[0079] See also Figure 8 One side of the extrusion piston 24 is fixedly connected to an extrusion rod 241, and one side of the extrusion piston 25 is fixedly connected to an extrusion rod 251. The free end of the extrusion rod 251 slides and seals through the end of the extrusion cylinder 21 and is connected to the extrusion mechanism 23 in a transmission manner. The free end of the extrusion rod 241 slides and seals through the extrusion piston 25 and the extrusion rod 251 and is connected to the extrusion mechanism 23 in a transmission manner. The extrusion mechanism 23 is used to drive the extrusion rod 241 and the extrusion rod 251 to move relative to each other. The extrusion rod 241 is used to drive the extrusion piston 24 to slide in the extrusion cylinder 21, and the extrusion rod 251 is used to drive the extrusion piston 25 to slide in the extrusion cylinder 21.

[0080] By providing the squeezing mechanism 23 , the squeezing rod 1 241 and the squeezing rod 251 can be driven to move relative to each other, so that the squeezing piston 1 24 and the squeezing piston 2 25 can be made to move relative to each other, thereby compressing the space between the squeezing piston 1 24 and the squeezing piston 2 25 , and the repair glue can be sprayed out from the spray pipe 20 .

[0081] By bidirectionally arranging the extrusion piston 1 24 and the extrusion piston 2 25 and making the extrusion piston 1 24 and the extrusion piston 2 25 move relative to each other for compression, the compression efficiency can be significantly improved, and the energy of the repair glue sprayed into the liquid storage box 19 can be further increased, thereby better cleaning and gluing the bristles 18.

[0082] Two side connecting rods 242 are symmetrically installed on both sides of the extrusion rod 251 extending out of one end of the extrusion cylinder 21. The extrusion mechanism 23 includes two extrusion units. For details, please refer to Figure 10 The two extrusion units are symmetrically arranged and are respectively arranged on both sides of the extrusion rod 241.

[0083] Among them, the extrusion unit includes a bending rod 32 and a connecting rod driving mechanism. The bending rod 32 is vertically fixed at the top end of the bottom plate 2102, and the top end of the bending rod 32 is bent inward. The bending rod 32 mainly plays a role in supporting the entire connecting rod driving mechanism.

[0084] In this embodiment, the connecting rod driving mechanism includes a first hinge member 26. One end of the first hinge member 26 is hinged to the side connecting rod 242, and the other end of the first hinge member 26 is coaxially hinged with a second hinge member 27 and a third hinge member 29.

[0085] Among them, the free end of the second hinge member 27 is hinged to a fixed hinge member 28 vertically and fixedly installed inside the bending rod 32.

[0086] The free end of the third hinge member 29 is coaxially hinged with a fourth hinge member 30 and a fifth hinge member 31.

[0087] Among them, the free end of the fourth hinge member 30 is hinged to a linkage rod 33. The middle of the linkage rod 33 is fixedly connected to the end of the first extrusion rod 241. Specifically, both ends of the linkage rod 33 are hinged to the fourth hinge members 30 of two connecting rod driving mechanisms.

[0088] At the same time, a collar 3201 is integrally connected to the top end of the bending rod 32. A rotating pin is rotatably sleeved on the collar 3201. The free end of the fifth hinge member 31 is fixedly sleeved on the bottom end of the rotating pin. After the top end of the rotating pin extends out of the collar 3201, it is fixedly sleeved with a meshing gear 34. The meshing gears 34 of two extrusion units mesh with each other.

[0089] Among them, the second hinge member 27 and the third hinge member 29 rotate synchronously, and the fifth hinge member 31 and the third hinge member 29 rotate synchronously. That is, the hinged ends of the second hinge member 27 and the third hinge member 29 are fixedly sleeved by a pin shaft, and the hinged ends of the fifth hinge member 31 and the third hinge member 29 are fixedly sleeved by a pin shaft. When the third hinge member 29 rotates, it can drive the second hinge member 27 and the fifth hinge member 31 to rotate synchronously.

[0090] In this embodiment, the hinge point of the second hinge member 27 and the fixed hinge member 28 is arranged directly below the collar 3201.

[0091] In this embodiment, a driving device is installed at the bottom end of one of the fixed hinges 28, which is used to drive the second hinge 27 to swing. Since the second hinge 27, the third hinge 29 and the fifth hinge 31 rotate synchronously, they can drive the first hinge 26 to reciprocate along the length direction of the extrusion rod 241, and can also drive the connecting rod 33 to reciprocate, so that the side connecting rod 242 can drive the extrusion rod 251 to move, and at the same time, the connecting rod 33 can drive the extrusion rod 241 to move, and the two meshing gears 34 are meshed with each other, so that the driven meshing gear 34 can drive the first hinge 26, the second hinge 27, the third hinge 29 and the fourth hinge 30 of the other extrusion unit to move synchronously, and then synchronously drive the connecting rod 33 and the other side connecting rod 242 to move.

[0092] At the same time, since the second hinge 27 and the third hinge 29 rotate synchronously, the fifth hinge 31 and the third hinge 29 rotate synchronously, when the third hinge 29 rotates, the first hinge 26 and the fourth hinge 30 always maintain relative movement, that is, the first hinge 26 and the fourth hinge 30 approach each other or move away from each other, so that the extrusion rod 1 241 and the extrusion rod 2 251 approach each other or move away from each other, realizing repeated compression inside the extrusion cylinder 21, and continuous compression operation can be achieved.

[0093] Furthermore, four supporting legs 2101 are fixedly connected between the extrusion cylinder 21 and the bottom plate 2102, and the supporting legs 2101 are evenly distributed on both sides of the extrusion cylinder 21. The arrangement of the supporting legs 2101 can ensure the stability of the extrusion cylinder 21, which is suitable for promotion and use.

[0094] The working principle of the present invention is as follows: when the tube body 100 needs to be repaired, the tube body 100 is first placed on one of the support frames 200 by hoisting, and then one end passes through the support ring 201 and the elastic sleeve ring 3 in sequence, and then the end of the tube body 100 is placed on another support frame 200, and it is ensured that one of the toggle grooves 301 on the elastic sleeve ring 3 is clamped between the limit block 1501 and the swing rod 14.

[0095] After the tube body 100 is placed and its stability is confirmed, the transmission rod 13 can be driven to rotate by the driving device. The rotation of the transmission rod 13 can drive the fourth hinged rod 1301 to swing. When the fourth hinged rod 1301 swings, the free end of the fourth hinged rod 1301 can drive the first hinged rod 7 to move, and the free end of the first hinged rod 7 can push the second hinged rod 8 to swing downward. Since the second hinged rod 8 and the end of the driving rod 6 are fixedly sleeved, when the second hinged rod 8 swings downward, the driving rod 6 will rotate synchronously. Since one end of the third hinged rod 9 is fixedly sleeved with the driving rod 6, the driving rod 6 can drive the free end of the third hinged rod 9 to swing upward, so that the third hinged rod 9 can lift the vertical rod 10.

[0096] Since the free end of the third hinge rod 9 makes a circular swinging motion, when the vertical rod 10 is lifted, the vertical rod 10 gradually changes from lifting upward to lateral movement under the cooperation of the chute 11 and the slider 12. Furthermore, the bristles 18 at the bottom end of the repair plate 17 can be horizontally attached to the pipe body 100, and the repair glue on the bristles 18 can be applied to the surface of the pipe body 100 to repair the surface of the pipe body 100.

[0097] Meanwhile, the transmission rod 13 rotates to drive the swing rod 14 and the arc-shaped block 16 to rotate. The swing rod 14 rotates to drive the toggle rod 15 to rotate. Due to the relationship that the toggle rod 15 and the toggle groove 301 are movably clamped, the elastic socket ring 3 can be periodically rotated by the toggle rod 15. Each time a toggle groove 301 is toggled, the elastic socket ring 3 rotates by a fixed angle. Thus, the pipe body 100 sleeved in the elastic socket ring 3 can be rotated by a fixed angle. With the setting of the link transmission mechanism, the repair plate 17 and the bristles 18, after the pipe body 100 rotates by a fixed angle each time, the repair glue can be applied to the pipe body 100 for repair. It can not only repair the surface of the pipe body 100 in all directions, effectively reduce the operation burden of the repair personnel, but also achieve uniform coating repair of the surface of the pipe body 100.

[0098] At the same time, through the setting of the liquid spraying mechanism, the repair glue in the liquid storage box 19 can be replenished at any time. By driving the second hinge 27 to swing through the driving device, since the second hinge 27, the third hinge 29 and the fifth hinge 31 rotate synchronously, it can not only drive the first hinge 26 to make a reciprocating motion along the length direction of the extrusion rod one 241, but also drive the linkage rod 33 to make a reciprocating motion. Thus, the side connecting rod 242 can drive the extrusion rod two 251 to move, and at the same time, the linkage rod 33 can drive the extrusion rod one 241 to move. And the two meshing gears 34 are meshed with each other, so that the driven meshing gear 34 can drive the first hinge 26, the second hinge 27, the third hinge 29 and the fourth hinge 30 of another extrusion unit to move synchronously, and further synchronously drive the linkage rod 33 and another side connecting rod 242 to move.

[0099] Meanwhile, since the second hinge 27 and the third hinge 29 rotate synchronously, and the fifth hinge 31 and the third hinge 29 rotate synchronously, when the third hinge 29 rotates, the first hinge 26 and the fourth hinge 30 always maintain relative movement, that is, the first hinge 26 and the fourth hinge 30 approach or move away from each other, so that the first extrusion rod 241 and the second extrusion rod 251 approach or move away from each other, realizing repeated compression inside the extrusion cylinder 21, and continuous compression operation can be achieved. The repair glue in the extrusion cylinder 21 is sprayed into the liquid storage box 19 by means of compressed spraying, so that the repair glue sprayed into the liquid storage box 19 can spray and wash the bristles 18, which can not only assist the bristles 18 to adhere to the repair glue, but also spray and wash away the residues or oxidized waste chips left after the bristles 18 smear the pipe body 100, preventing the impurities remaining on the bristles 18 from affecting the repair of the pipe body 100.
