Description

Technical Field

[0001] This invention relates to the field of novel pipe fittings manufacturing technology, and in particular to a continuous winding glass fiber reinforced plastic jacking pipe forming production line and process. Background Technology

[0002] Continuously wound glass fiber reinforced plastic (CWFP) jacking pipe is a new type of composite material pipe with a three-dimensional reinforced structure, using glass fiber as the reinforcing material, resin as the matrix, and quartz sand as the filler. It is continuously and rapidly molded using 3D printing technology. Because CWFP pipes possess both the mechanical properties of metal pipes and the hydraulic and corrosion-resistant properties of plastic pipes, they are widely used in water supply and drainage engineering, petrochemical engineering, marine engineering, and agricultural and forestry water conservancy projects.

[0003] Pipe jacking is an underground pipeline construction method developed after shield tunneling. It eliminates the need for surface excavation and can traverse highways, railways, rivers, surface buildings, underground structures, and various underground pipelines. Pipe jacking utilizes the thrust of the main jacking cylinder and intermediate sections between pipe sections to push the tool pipe or tunneling machine through the soil from the working shaft to the receiving shaft, where it is then lifted. Simultaneously, the pipeline following the tool pipe or tunneling machine is buried between the two shafts, achieving a trenchless underground pipeline laying method.

Both the first and second fixing plates are provided with clamping plates for holding and fixing the jacking pipe, and a driving unit for driving the two clamping plates closer or further apart. The assembly also includes a first threaded rod disposed at the bottom of the second fixing plate and threadedly connected to the second fixing plate, and a first motor for driving the first threaded rod to rotate. Multiple rollers are evenly arranged on the inner sidewall of the clamping plates, and the lowest roller is driven by a motor. Preferably, the fitting includes an extension rod for picking up the sealing ring and having a vacuum suction cup at its end, a fixed frame for slidingly connecting the extension rod in the horizontal direction, and a buffer rod that is slidably connected to the fixed frame and moves synchronously with the extension rod through a gear and rack transmission.

[0009] Preferably, the pressure testing mechanism includes a placement platform for placing pipe fittings and having fixing holes on both sides, a sealing plate for placing water pressure testing equipment on both sides of the placement platform and having a water pressure testing device on top, a second threaded rod rotatably connected to the placement plate and having its two ends threadedly connected to the sealing plate, a third gear connected to the second threaded rod via a belt and located near the fixing holes, and a mounting frame located below the placement platform and causing the placement platform to rotate.

[0010] Preferably, the stacking mechanism includes a moving part for transferring pipe fittings and a stacking part for storing pipe fittings. The moving part includes a transfer frame disposed behind the pressure measuring mechanism, a slide rail slidably connected to the transfer frame, a third threaded rod rotatably connected to the slide rail at both ends and threadedly connected to the transfer frame, a fourth gear connected to one end of the third threaded rod via a belt and rotatably connected to one side of the slide rail, and a lifting platform for fixing the first linear motor and the transfer frame.

[0011] Preferably, the stacking component includes a stacking platform disposed on both sides of the slide rail, two sets of chains disposed on both sides of the stacking platform, a sprocket for driving the chains to rotate, multiple sets of connecting frames fixed on the chains, a support plate hinged to the connecting frames, a ratchet that drives the sprockets through a worm gear transmission, a second motor whose output shaft is fixedly connected to the internal teeth of the ratchet and mounted on the stacking platform, and a third rack fixedly connected to both sides of the lifting platform and capable of meshing with the external teeth of the ratchet.

[0012] Preferably, the hoisting mechanism includes a gantry for position movement and a clamping component disposed on the gantry moving block. The clamping component includes a control frame disposed on the gantry moving block, a fourth threaded rod rotatably connected to the control frame and driven by a motor, a lifting frame slidably connected to the control component and threadedly connected to the fourth threaded rod, a drive plate rotatably connected to the lifting frame and driven by a third motor, and a clamping arm disposed on the drive plate for clamping pipe fittings.

[0013] Preferably, the clamping member further includes a fourth rack and a fifth rack respectively disposed on both sides of the drive plate. During the movement of the lifting frame, the fourth rack can mesh with the third gear and the fifth rack can mesh with the fourth gear.

[0014] As a further preferred embodiment, the production process of the continuously wound glass fiber reinforced plastic jacking pipe forming production line is characterized by comprising the following steps: Step 1, Production Steps: The continuous winding machine in the production mechanism produces and shapes the sleeve. During the production process, when the sleeve reaches a certain thickness, the first electric cylinder pushes the push plate to move, so that the rotating frame contacts the drive plate. The continuous winding machine rotates and the fixing block adheres the metal sheet to the surface of the incompletely formed sleeve to continue winding, thus embedding the metal sheet on the sleeve. At the same time, the cutting machine is used to cut the top pipe, and the cut pipe is fixed to the second fixing plate and the first fixing plate. The second fixing plate moves away from the first fixing plate. Step two, assembly step: The clamping arm on the hoisting mechanism clamps the sleeve and moves it between the first fixed plate and the second fixed plate via the gantry frame. During the movement, the sleeve adheres to the buffer rod, causing the buffer rod to move. The buffer rod drives the fixed frame to move towards the sleeve through the transmission of gears and racks. The sealing ring is picked up by a vacuum suction cup on the fixed frame and moved to the surface of the opening between the jacking pipe and the sleeve. After the movement is completed, the rollers inside the clamping plates on the first and second fixed plates rotate, driving the jacking pipe rotation rod. At the same time, the gantry frame moves the sleeve towards the first fixed plate and the second fixed plate towards the sleeve. The jacking pipe on the second fixed plate pushes the sealing ring into the sleeve, thus inserting the jacking pipe on the first and second fixed plates into the sleeve, completing the assembly of the pipe fittings. Step 3: Inspection Steps. The assembled pipe fittings are moved to the top of the inspection mechanism by the gantry frame and slowly descend. During the descent, the fourth and fifth racks are inserted into the fixing holes on both sides of the placement platform. At the same time, the fourth rack meshes with the third gear during the descent. The third gear drives the sealing plates at both ends to move closer to the middle and contact the openings at both ends of the pipe fitting, placing the pipe fitting on the placement platform. The third motor drives the drive plate to rotate, causing the pipe fitting and the placement platform to rotate. The water pressure testing equipment set on the sealing plate performs water pressure testing. Step four, stacking step: The pipe fittings that have completed the water pressure test are moved to the front of the stacking platform and lowered. The fifth rack meshes with the fourth gear, and the fourth gear drives the third threaded rod to rotate, driving the transfer frame to move below the pipe fittings. The pipe fittings are placed on the transfer frame, the control frame moves up, and the transfer frame is driven to move into the stacking platform. The stacking platform rises and then falls. The third rack meshes with the ratchet, driving the chain to rotate through the worm gear. The chain moves, causing the connecting frame and the pallet to rise. The pallets on both sides together lift the pipe fittings and move them upward, thus stacking the pipe fittings.

[0015] The beneficial effects of this invention are: (1) In this invention, by setting up a production mechanism, metal sheets are embedded in the sleeve during the continuous winding production process of the sleeve. The process of embedding the metal sheets does not affect the normal continuous winding production process, so that the metal sheets and the sleeve are tightly connected, ensuring the production quality of the sleeve. (2) In this invention, by setting up a combination mechanism, the automatic assembly of pipe fittings is realized. The force generated by the second fixing plate during the installation process promotes the process of the sleeve being installed onto the first fixing plate. The positioning work before installation is ensured by the mating parts, and the collision between the jacking pipe and the sleeve during installation is reduced. (3) In this invention, by setting up a stacking mechanism, the pipe fittings are stacked efficiently. The pipe fittings are lifted by the stacking components, and the pipe fittings are lifted up layer by layer in the installation order to achieve stacking. At the same time, the lifting control chain of the lifting platform is used to move the pallet that has been stacked with pipe fittings to rise, and new pipe fittings are added to the stacking queue. (4) In this invention, a hoisting mechanism is set up to achieve working connection with the assembly mechanism, pressure measuring mechanism and stacking mechanism. The movement of the hoisting mechanism promotes the operation of the assembly mechanism, pressure measuring mechanism and stacking mechanism, thereby improving work efficiency.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1 like Figure 1 As shown, a continuously wound glass fiber reinforced plastic jacking pipe molding production line includes: Production mechanism 1, which is used to produce and shape the sleeve. Assembly mechanism 2, located behind production mechanism 1, is used to assemble the jacking pipe and the sleeve. Pressure testing mechanism 3, which is located behind assembly mechanism 2 and is used to test the sealing performance of assembled pipe fittings. Stacking mechanism 4, which is located behind pressure measuring mechanism 3 and is used to stack the pipe fittings after testing. The hoisting mechanism 5 is located above the production mechanism 1 and is used to hoist the pipe fittings. It also works in conjunction with the combination mechanism 2, the pressure measuring mechanism 3 and the stacking mechanism 4.

[0033] In this embodiment, the pipe fittings are assembled by setting up the assembly mechanism 2 and the stacking mechanism 4. After assembly, a sealing test is performed to prevent the pipe fittings from having poor sealing. After the test is completed, the pipe fittings are stacked efficiently.

[0034] In detail, the sleeve in the pipe fitting is produced by production mechanism 1, in which metal sheets are embedded. After the sleeve is formed, it is moved to assembly mechanism 2 and combined with the top pipes at both ends. The two top pipes and one sleeve are combined to form a complete pipe fitting. The assembled sleeve is tested for sealing to ensure the airtightness of the pipe fitting. The pipe fitting that has passed the test enters stacking mechanism 4 for orderly stacking. During the entire production and assembly process, the pipe fitting is moved by hoisting mechanism 5.

[0035] It should be noted that the production mechanism 1 completes the production of the sleeve in the pipe fitting, and the assembly mechanism 2 cuts the jacking pipe in the pipe fitting. It is an improvement on the existing method of repairing continuously wound glass fiber reinforced plastic pipe, so that the pipe fitting can achieve the original effect with only two jacking pipes, one sleeve and one sealing ring.

[0036] It is worth mentioning that by setting up multiple mechanisms on the production line, the assembly line production of pipe fittings can be realized, thereby improving the uniformity and standardization of pipe fitting production.

[0037] Furthermore, such as Figure 2 , Figure 3 As shown, the production mechanism 1 includes a continuous winding machine 11 for forming sleeves and a placement assembly 12 for placing metal sheets on the continuous winding machine 11. The placement assembly 12 includes: A fixing block 121 is disposed on one side of the continuous winding machine 11 and is used to pick up and move the metal sheet. A vacuum suction cup is provided on the fixing block 121. A rotating frame 123 is slidably connected to a movable block at its outer end and is rotatably connected to a push plate 122 about the rotating shaft of the continuous winding machine 11. A cavity is provided inside the rotating frame 123. Push plate 122, which is slidably connected to the telescopic rod of the first electric cylinder 127; The control rod 124 has its two ends respectively mounted on the rotating frame 123 and the fixed block 121, and has two short shafts hinged in the middle. The control rod 124 is located in the cavity of the rotating frame 123. A drive disk 125 is slidably connected to a rotating frame 123 and a spring is provided between the drive disk 125 and the rotating frame 123. Push rod 126 is mounted on drive disc 125 and extends into cavity of rotating frame 123. Push rod 126 is located in the middle of two short shafts of control rod 124. In this embodiment, by setting a fixing block 121 and a rotating component, the metal sheet is pre-embedded, so that the metal sheet can be set into the sleeve in advance during the winding process without affecting the original winding process.

[0038] In detail, the continuous winding machine 11 winds and shapes the sleeve. When the shape reaches a certain thickness, the telescopic rod of the first electric cylinder 127 extends, pushing the push plate 122 to move towards the continuous winding machine 11. The rotating frame 123 on the push plate 122 and the drive plate 125 move towards the continuous winding machine 11 at the same time. The drive plate 125 contacts the continuous winding machine 11 and simultaneously adheres to the rotating frame 123, causing the rotating frame 123 to rotate with the continuous winding machine 11. The push rod 126 fixed on the drive plate 125 pushes the control rod 124, causing the two short shafts on the control rod 124 to bend and pull the fixing block 121. The fixing block 121 moves towards the center of the rotating shaft, causing the metal sheet to adhere to the surface of the sleeve for continued winding and shaping. After the metal sheet is fixed, the telescopic rod of the first electric cylinder 127 shortens, the drive plate 125 disengages from the continuous winding machine 11, and the fixing block 121 disengages from the metal sheet, completing the pre-embedding of the metal sheet.

[0039] It should be noted that the FRP continuous winding machine 11 is mainly used for winding the external protective layer of insulated pipes and for anti-corrosion of the outer wall of steel pipes. It is a piece of equipment used in the production of FRP storage tanks and pipes. The winding machine mainly consists of three parts: first, the main spindle system, driven by a main spindle motor; second, the trolley system, driven by a trolley motor, which moves the trolley along the axis on the machine bed, causing the guide wire head to make linear reciprocating motion; and third, the control system, a microcomputer control system that automatically controls the entire production process through parameter settings.

[0040] The main shaft system of the continuous winding machine 11 is equipped with a pattern plate for fixing the inner core mold. The first electric cylinder 127 is installed on the housing of the continuous winding machine 11. After the first electric cylinder 127 is started, the drive disc 125 contacts the pattern plate on the continuous winding machine 11 to drive the placement component 12 to work.

[0041] The setting of the drive disc 125 makes the metal sheet setting process more efficient. The metal sheet will not affect the normal sleeve production process before it is embedded, and the metal sheet is rotating together with the continuous winding machine 11 during the embedding process, thereby improving production efficiency.

[0042] It is worth mentioning that by setting elastic elements between the drive plate 125 and the rotating frame 123, and between the rotating frame 123 and the fixed block 121, the fixed block 121 can be rapidly detached after the metal sheet is embedded, thus avoiding the fixed block 121 from affecting the winding molding process.

[0043] Furthermore, such as Figure 4-6As shown, the assembly mechanism 2 includes a cutting machine 21 for slitting the jacking pipe and an assembly 22 for assembling the jacking pipe and the sleeve. The assembly 22 includes a first fixing plate 221, a second fixing plate 222, and a mating component 223 for assembly. The first fixing plate 221 and the second fixing plate 222 are each provided with a clamping plate 2211 for clamping and fixing the jacking pipe and a driving unit for driving the two clamping plates 2211 to move closer or further apart. The assembly 22 also includes a first threaded rod 224 provided at the bottom of the second fixing plate 222 and threadedly connected to the second fixing plate 222, and a first motor 225 for driving the first threaded rod 224 to rotate. The inner sidewall of the clamping plate 2211 is evenly provided with a plurality of rollers 226, and the lowest roller 226 is driven by a motor.

[0044] In this embodiment, by setting a first fixing plate 221 and a second fixing plate 222, the cutting machine 21 is used to cut and move the jacking pipe. After the jacking pipe is cut and the root is split, the first fixing plate 221 fixes the jacking pipe and moves it away. Then the second fixing plate 222 fixes the jacking pipe that has been cut again. There is a gap between the two jacking pipes that can accommodate the sleeve so that they can be combined.

[0045] In detail, when the jacking pipe moves onto the first fixed plate 221 or the second fixed plate 222, the drive unit drives the clamping plate 2211 to clamp and fix the jacking pipe. The first motor 225 drives the first threaded rod 224 to rotate. The first threaded rod 224 drives the second fixed plate 222 to disengage from the first fixed plate 221. When the sleeve moves between the first fixed plate 221 and the second fixed plate 222, the motor drives the roller 226 to rotate, causing the jacking pipe clamped by the clamping plate 2211 to rotate. At the same time, the first motor 225 moves in conjunction with the gantry frame 51 to move the sleeve toward the first fixed plate 221. The first fixed plate 221 moves toward the sleeve, inserting the two jacking pipes into the sleeve.

[0046] It should be noted that a locking block is required in the middle of the sleeve to place the sealing ring and allow the top tubes at both ends to extend to the same length. The locking block can be directly set on the inner core mold of the sleeve winding.

[0047] For the jacking pipe of the input assembly mechanism, a continuous winding machine 11 is also used for production. After the produced jacking pipe is left to stand for 3-4 hours, it is cut by a cutting machine 21. After cutting, the two ends of the jacking pipe need to be ground, coated with resin, and lubricated to facilitate the subsequent assembly process. Specifically, after grinding, resin is applied to both ends of the jacking pipe. Before applying resin, the ends need to be inspected to check if the wall thickness is uniform and if the chamfer is normal. When applying resin, it should be applied in small amounts multiple times, evenly. After the resin cures, there should be no resin nodules, no height differences, and no burrs at the ends. After the resin dries, lubricant is also applied to the pipe ends.

[0048] It is worth mentioning that by setting rollers 226 on the clamping plate 2211, the jacking pipe can rotate on the clamping plate 2211, and the rotation of the jacking pipe makes it easier to combine the jacking pipe and the sleeve.

[0049] Furthermore, such as Figure 7 As shown, the mating component 223 includes an extension rod 2231 for picking up the sealing ring and having a vacuum suction cup at its end; a fixing frame 2232 that allows the extension rod 2231 to slide horizontally; a buffer rod 2233 that is slidably connected to the fixing frame 2232; a first rack 2234 fixed to the extension rod 2231; a second rack 2235 fixed to the buffer rod 2233; a first gear 2236 meshing with the first rack 2234; and a second gear 2237 that is connected to the first gear 2236 via a belt and meshes with the second rack 2235. In this embodiment, by setting the fixing frame 2232 and the buffer rod 2233, the sleeve position is positioned and the sealing ring is placed at the same time, making the assembly process more efficient and avoiding collision damage between the top pipe and the sleeve.

[0050] In detail, when the gantry 51 hoisting sleeve moves towards the middle of the first fixed plate 221 and the second fixed plate 222, the buffer rod 2233 first contacts the sleeve. As the sleeve moves, the buffer rod 2233 moves, the second rack 2235 drives the second gear 2237 to rotate, the second gear 2237 drives the first gear 2236 to rotate, and the first gear 2236 drives the first rack 2234 and the extension rod 2231 to move towards the sleeve. The sliding stroke of the buffer rod 2233 contacts and stops moving, causing the sleeve to stop moving and keeping the sleeve in a fixed position. At the same time, the sealing ring on the extension rod 2231 moves to the opening of the sleeve. As the second fixed plate 222 moves, the jacking pipe pushes the sealing ring into the sleeve.

[0051] It is worth mentioning that the setting of the buffer rod 2233 and the extension frame keeps the position of the sleeve fixed, aligning the sleeve with the jacking pipe. Furthermore, the connection between the buffer rod 2233 and the extension frame ensures that the setting of the sealing ring is always fixed, thus aligning the sleeve with the jacking pipe.

[0052] Furthermore, such as Figure 8 As shown, the pressure testing mechanism 3 includes a placement platform 31 for placing pipe fittings and having fixing holes 311 on both sides, a sealing plate 32 for placing water pressure testing equipment on both sides of the placement platform 31 and above it, a second threaded rod 33 rotatably connected to the placement plate and threaded to the sealing plate 32 at both ends, a third gear 34 connected to the second threaded rod 33 by a belt and located near the fixing holes 311, and a mounting bracket 35 located below the placement platform 31 and causing the placement platform 31 to rotate.

[0053] In this embodiment, water pressure testing of the pipe fitting is achieved by setting a sealing plate 32 and a placement platform 31. The two ends of the pipe fitting are blocked by the sealing plate and water pressure testing is performed. By rotating the placement platform 31 installed on the mounting bracket 35, the pipe fitting can rotate during the testing process, further enhancing the testing effect.

[0054] In detail, the third gear 34 drives the second threaded rod 33 to rotate, and the second threaded rod 33 drives the sealing plates 32 at both ends to move closer to the middle. The sealing plates 32 fit into the two ends of the pipe to seal, and after sealing, a water pressure test is performed.

[0055] It should be noted that the side of the sealing plate 32 that contacts the pipe fitting should be properly sealed to prevent water leakage at the gap between the sealing plate 32 and the pipe fitting.

[0056] It is worth mentioning that by rotating the placement platform 31, the pipe fitting can be rotated during the water pressure test. This rotation allows the surface of the pipe fitting to withstand greater pressure, thus improving the test results.

[0057] Furthermore, such as Figure 9 As shown, the stacking mechanism 4 includes a moving part 41 for transferring pipe fittings and a stacking part 42 for storing pipe fittings. The moving part 41 includes a transfer frame 411 disposed behind the pressure measuring mechanism 3, a slide rail 412 slidably connected to the transfer frame 411, a third threaded rod 413 rotatably connected to the slide rail 412 at both ends and threadedly connected to the transfer frame 411, a fourth gear 414 connected to one end of the third threaded rod 413 via a belt and rotatably connected to one side of the slide rail 412, and a lifting platform 415 for fixing the first linear motor and the transfer frame 411.

[0058] In this embodiment, by setting the transfer frame 411 and the fourth gear 414, the position of the transfer frame 411 can be moved, so that the transfer frame 411 can be associated with the movement of the hoisting mechanism 5, and the rotation of the fourth gear 414 drives the transfer frame 411 to move the pipe.

[0059] In detail, the hoisting mechanism 5 moves the pipe above the slide rail 412, the pipe descends, the hoisting mechanism 5 drives the fourth gear 414 to rotate, the fourth gear 414 drives the third threaded rod 413 to rotate, causing the transfer frame 411 to move. The transfer frame 411 is moved below the pipe, the hoisting mechanism 5 places the pipe on the transfer frame 411 and then rises, and the fourth gear 414 is driven to reverse again, so that the transfer frame 411 moves the pipe into the stacking component 42.

[0060] It should be noted that the fourth gear 414 drives the third threaded rod 413 to rotate, thereby moving the transfer frame 411. It is necessary to consider that the transmission ratio between the third threaded rod 413 and the fourth gear 414 needs to meet a certain value.

[0061] It is worth mentioning that the movement of the transfer frame 411 is associated with the hoisting mechanism 5 through the setting of the fourth gear 414, so that the transfer frame 411 and the hoisting mechanism 5 cooperate to complete the movement of the pipe fitting.

[0062] Furthermore, such as Figure 10-12 As shown, the stacking component 42 includes a stacking platform 421 disposed on both sides of the slide rail 412, two sets of chains 422 disposed on both sides of the stacking platform 421, a sprocket 423 driving the chains 422 to rotate, multiple sets of connecting frames 429 fixed on the chains 422, a support plate 430 hinged to the connecting frame 429, a worm gear 424 connected to the sprocket 423 via a belt and rotatably connected to the stacking platform 421, a worm 425 meshing with the worm gear 424 and rotatably connected to the stacking platform 421, a ratchet 426 whose internal teeth are fixedly connected to the worm 425, a second motor 427 whose output shaft is fixedly connected to the internal teeth of the worm 425 and mounted on the stacking platform 421, and a third rack 428 fixedly connected to both sides of the lifting platform 415 and capable of meshing with the external teeth of the ratchet 426.

[0063] In this embodiment, by setting a third rack 428 and a chain 422, multiple transmission structures are used to lift and stack the pipes. When a pipe is fed into the transfer frame 411, the chain 422 is driven to rotate synchronously, and the pallet 430 is used to lift the pipe and move it upward in sequence.

[0064] In detail, the lifting platform 415 lifts the pipe fitting a certain distance and then lowers it. During the descent, the third rack 428 drives the ratchet 426 to rotate, the ratchet 426 drives the worm gear 425 to rotate, the worm gear 425 drives the worm wheel 424 and the sprocket 423 to rotate, the sprocket 423 drives the chain 422 to rotate, and the connecting frame 429 and the pallet 430 on the chain 422 move upward to lift the pipe fitting located on the transfer frame 411. As subsequent pipe fittings are input, the previously placed pipe fitting can continue to move upward.

[0065] It should be noted that the pallet 430 is hinged to the upper part of the connecting frame 429, and the lower end of the connecting piece constrains the connecting frame 429, so that the pallet 430 can remain stable during the lifting process.

[0066] It is worth mentioning that the ratchet 426 is driven by the second motor 427, which can drive the sprocket 423 to reverse. The chain 422 is used to move the pipe that has been lifted to the top down for easy access later. At the same time, the worm gear is used to achieve self-locking of the device and prevent it from falling under the pressure of the pipe above.

[0067] Furthermore, such as Figure 13As shown, the hoisting mechanism 5 includes a gantry frame 51 for realizing position movement and a clamping member 52 disposed on the moving block of the gantry frame 51. The clamping member 52 includes a control frame 521 disposed on the moving block of the gantry frame 51, a fourth threaded rod 522 rotatably connected to the control frame 521 and driven by a motor, a lifting frame 523 slidably connected to the control member and threadedly connected to the fourth threaded rod 522, a drive plate 525 rotatably connected to the lifting frame 523 and driven by a third motor 524, and a clamping arm 526 disposed on the drive plate 525 for clamping pipe fittings.

[0068] In this embodiment, the position of the pipe is moved by setting up a lifting frame 523 and a drive plate 525.

[0069] In detail, the sleeve is clamped by the clamping arm 526, the fourth threaded rod 522 is driven by the motor to rotate, causing the lifting frame 523 to move up and down, and the pipe is rotated by the drive plate 525.

[0070] It should be noted that when the pipe fitting is subjected to water pressure testing, the pipe fitting is placed on the placement platform 31. At this time, the third motor 524 drives the drive plate 525 to rotate, which in turn drives the pipe fitting to rotate, thus assisting in the water pressure testing of the pipe fitting.

[0071] Furthermore, such as Figure 13 As shown, the clamping member 52 also includes a fourth rack 527 and a fifth rack 528 respectively disposed on both sides of the drive plate 525. During the movement of the lifting frame 523, the fourth rack 527 can mesh with the third gear 34, and the fifth rack 528 can mesh with the fourth gear 414.

[0072] In this embodiment, by setting the fourth rack 527 and the fifth rack 528, the hoisting mechanism 5 can cooperate with the pressure measuring mechanism 3 and the stacking mechanism 4, and the hoisting mechanism 5 facilitates the working process of the pressure measuring mechanism 3 and the stacking mechanism 4.

[0073] In detail, when the pipe moves into the pressure testing mechanism 3, the pipe descends, the fourth rack 527 drives the third gear 34 to rotate, and drives the sealing plate 32 to seal the pipe. At the same time, the fourth rack 527 and the fifth rack 528 are inserted into the fixing hole 311, so that the driving plate 525 directly drives the placement platform 31 to rotate, avoiding excessive pressure on the surface of the pipe.

[0074] When the pipe fittings are stacked, the fifth rack 528 meshes with the fourth gear 414, driving the transfer frame 411 to move, thus facilitating the smooth transport of the pipe fittings by the transfer frame 411. It should be noted that by setting the fourth rack 527 and the fifth rack 528 respectively, compared with setting a single rack to drive the third gear 34 and the fourth gear 414 in sequence, it is beneficial to maintain the stability of the clamping member 52 and facilitates the direct transmission of force in the detection mechanism.

[0075] Example 2 Furthermore, such as Figure 14 As shown, the production process of the continuously wound glass fiber reinforced plastic jacking pipe forming production line includes the following steps: Step 1, Production Steps: The continuous winding machine 11 in production mechanism 1 produces and shapes the sleeve. During the production process, when the sleeve reaches a certain thickness, the first electric cylinder 127 pushes the push plate 122 to move, so that the rotating frame 123 contacts the drive disk 125. During the rotation process, the continuous winding machine 11 makes the fixing block 121 attach the metal sheet to the surface of the incompletely formed sleeve and continue winding, so as to embed the metal sheet on the sleeve. At the same time, the cutting machine 21 is used to cut the top pipe and fix the cut pipe to the second fixing plate 222 and the first fixing plate 221. The second fixing plate 222 moves away from the first fixing plate 221. Step two, assembly step: The clamping arm 526 on the hoisting mechanism 5 clamps the sleeve and moves it between the first fixed plate 221 and the second fixed plate 222 via the gantry frame 51. During the movement, the sleeve adheres to the buffer rod 2233, causing the buffer rod 2233 to move. The buffer rod 2233 drives the fixed frame 2232 towards the sleeve through the transmission of the gear rack. The fixed frame 2232 uses a vacuum suction cup to pick up the sealing ring and moves it to the surface of the opening between the top pipe and the sleeve. After the movement is completed, the rollers 226 inside the clamping plates 2211 on the first fixed plate 221 and the second fixed plate 222 rotate, driving the top pipe rotation rod. At the same time, the gantry frame 51 drives the sleeve to move towards the first fixed plate 221 and the second fixed plate 222 towards the sleeve. The top pipe on the second fixed plate 222 pushes the sealing ring into the sleeve, thus inserting the top pipe on the first fixed plate 221 and the second fixed plate 222 into the sleeve, completing the assembly of the pipe fittings. Step 3: Inspection Step. The assembled pipe fitting moves to the top of the inspection mechanism under the movement of the gantry 51 and slowly descends. During the descent, the fourth rack 527 and the fifth rack 528 are inserted into the fixing holes 311 on both sides of the placement platform 31. At the same time, the fourth rack 527 meshes with the third gear 34 during the descent. The third gear 34 drives the sealing plates 32 at both ends to move closer to the middle and contact the openings at both ends of the pipe fitting, placing the pipe fitting on the placement platform 31. The third motor 524 drives the drive plate 525 to rotate, causing the pipe fitting and the placement platform 31 to rotate. The water pressure testing equipment set on the sealing plate 32 performs water pressure testing. Step four, stacking step: The pipe fittings that have completed the water pressure test are moved to the front of the stacking platform 421 and lowered. The fifth rack 528 meshes with the fourth gear 414. The fourth gear 414 drives the third threaded rod 413 to rotate, driving the transfer frame 411 to move below the pipe fittings. The pipe fittings are placed on the transfer frame 411. The control frame 521 moves upward, driving the transfer frame 411 to move into the stacking platform 421. The lifting platform 415 rises. After rising to a certain height, it descends. The third rack 428 on the lifting platform 415 meshes with the ratchet 426, driving the worm gear 425 to rotate. The worm gear 425 drives the worm wheel 424 to rotate. The worm wheel 424 drives the sprocket 423 to rotate and makes the chain 422 rotate. The chain 422 moves, causing the connecting frame 429 and the pallet 430 to rise. The pallets 430 on both sides lift the pipe fittings and move them upward, realizing the stacking of the pipe fittings.

The production process of a continuous winding glass fiber reinforced plastic jacking pipe forming production line according to any one of claims 1-7, characterized in that, Includes the following steps: Step 1, production steps, the continuous winding machine (11) in the production mechanism (1) produces and shapes the sleeve. During the production process, when the sleeve reaches a certain thickness, the first electric cylinder (127) pushes the push plate (122) to move, so that the rotating frame (123) contacts the drive disk (125) during the rotation of the continuous winding machine (11) and the fixing block (121) attaches the metal sheet to the surface of the sleeve that is not fully formed and continues to wind, so as to embed the metal sheet on the sleeve. At the same time, the cutting machine (21) is used to cut the top pipe and fix the cut pipe to the second fixing plate (222) and the first fixing plate (221) in turn. The second fixing plate (222) moves away from the first fixing plate (221). Step two, assembly step: The clamping arm (526) on the hoisting mechanism (5) clamps the sleeve and moves it between the first fixed plate (221) and the second fixed plate (222) through the gantry frame (51). During the movement, the sleeve is in contact with the buffer rod (2233), causing the buffer rod (2233) to move. The buffer rod (2233) drives the fixed frame (2232) to move towards the sleeve through the transmission of the gear rack. The fixed frame (2232) uses a vacuum suction cup to pick up the sealing ring and move the sealing ring to the top pipe. The movement is completed with the surface of the sleeve opening. The rollers (226) inside the clamping plate (2211) on the first fixed plate (221) and the second fixed plate (222) rotate, driving the jacking pipe rotating rod. At the same time, the gantry (51) drives the sleeve to move toward the first fixed plate (221) and the second fixed plate (222) to move toward the sleeve. The jacking pipe on the second fixed plate (222) pushes the sealing ring into the sleeve, realizing the insertion of the jacking pipe on the first fixed plate (221) and the second fixed plate (222) into the sleeve, completing the combination of the pipe fittings. Step 3, Inspection Step: The assembled pipe fitting moves to the top of the inspection mechanism under the movement of the gantry (51) and slowly descends. During the descent, the fourth rack (527) and the fifth rack (528) are inserted into the fixing holes (311) on both sides of the placement platform (31). At the same time, the fourth rack (527) meshes with the third gear (34) during the descent. The third gear (34) drives the sealing plates (32) at both ends to move closer to the middle and contact the openings at both ends of the pipe fitting, placing the pipe fitting on the placement platform (31). The third motor (524) drives the drive plate (525) to rotate, causing the pipe fitting and the placement platform (31) to rotate. The water pressure testing equipment set on the sealing plate (32) performs water pressure testing. Step four, stacking step: The pipe fittings that have completed the water pressure test are moved to the front of the stacking platform (421) and moved down. The fifth rack (528) meshes with the fourth gear (414). The fourth gear (414) drives the third threaded rod (413) to rotate and drive the transfer frame (411) to move below the pipe fittings. The pipe fittings are placed on the transfer frame (411). The control frame (521) moves up and drives the transfer frame (411) to move into the stacking platform (421). The lifting platform (415) rises and then falls. The third rack (428) meshes with the ratchet (426) and drives the chain (422) to rotate through the worm gear. The chain (422) moves and causes the connecting frame (429) and the pallet (430) to rise. The pallets (430) on both sides lift the pipe fittings together and move them up, thus realizing the stacking of the pipe fittings.
