[0002] Flexible composite pipes possess a range of advantages, including corrosion resistance, long single-section length, easy bending, light weight, and ease of transportation and construction, making them a crucial component of pipeline materials used in oil and gas fields both domestically and internationally. The sealing performance of pipe joints is a critical factor in ensuring the integrity of flexible composite pipe pipelines, and the flexible composite pipe joint crimping machine is a key piece of equipment for guaranteeing a tight connection between the flexible composite pipe and the joint.
[0003] Existing crimping machines for installing flexible composite pipe joints require multiple operators. After crimping, the machine must be lowered, the hoisting ropes removed and looped around the pipe, and then the machine hoisted back to another location. This process necessitates multiple operators, especially when inserting the pipe into the joint, which requires assistance from several people and various tools. This time-consuming and labor-intensive process reduces work efficiency. Therefore, these problems urgently need to be addressed. Summary of the Invention

Therefore, after each crimping is completed, there is no need to remove the outer clamping mold. This process saves time and effort and improves work efficiency.

The device is equipped with a connector clamp for installing the connector, and an outer clamp mold is coaxially embedded in the outer clamp mold mounting plate. Three horizontally arranged hydraulic cylinders II are evenly distributed and spaced along the circumferential direction between the outer clamp mold mounting plate and the support mounting plate. The piston rod of each hydraulic cylinder II extends horizontally to the left and vertically out of the outer clamp mold mounting plate, and is connected to the connector clamp mounting plate, thereby coaxially installing the connector in the connector clamp.

[0026] The drive assembly of this invention includes a lifting plate 1, a connecting shaft, a lifting ring 2, and a hydraulic cylinder I 3; as shownFigs. 1~3 As shown, the lifting plate 1 is a vertically arranged M-shape, and its three lower ends are rotatably connected to the middle position of the upper surface of the connecting plate II 6 and the upper side position of the two inclined surfaces through horizontally arranged connecting shafts. Lifting rings 2 are also symmetrically installed at intervals on the upper surface of the lifting plate 1, and the lifting operation of the clamping machine is carried out through the lifting rings 2. The front and rear ends of the upper surface of the lifting plate 1 extend in the front and rear directions, and a hydraulic cylinder I 3 is vertically arranged between its extended part and the upper inclined surface of the corresponding clamping plate II 23. The tail of each hydraulic cylinder I 3 is vertically hinged to the corresponding position of the front and rear ends of the lifting plate 1, and its piston rod is vertically hinged downward to the corresponding position of the upper inclined surface of the corresponding clamping plate II 23.

Its piston rod extends horizontally to the left, vertically extending from the left side of connecting plate II6 and connecting plate I4, and is fixedly connected to connecting plate I4 via a locking cap 10. The tails of the other two hydraulic cylinders II9 are horizontally positioned between each clamping plate II23 and its corresponding clamping plate III24. Furthermore, its tail ends are fixedly connected to the corresponding right side of the corresponding card plate II 23 and the corresponding left side of the corresponding card plate III 24, respectively.

At the lower end of the long side of the front side plate I22, relative to the positions of the two rear side insert plates I13, slots I are vertically embedded and matched with the insert plates I13. When the two plates I22 are rotated and closed, the two rear side insert plates are inserted into the corresponding slots I, thereby engaging the lower ends of the long sides of the two plates I22 together. At the lower end of the long side of the rear side plate II23, relative to the positions of the two rear side plates I22 and II23, semi-circular insert plates I13 are symmetrically arranged vertically at intervals on the left and right sides.

At the lower ends of the long sides of the two locking plates I22 and the lower ends of the long sides of the two locking plates II23, pin holes I14 that match pin shaft I15 are opened horizontally and coaxially. Each pin hole I14 passes horizontally through the corresponding insert plate I13, and the pin shaft I15 is coaxially inserted into the corresponding pin hole I14 to lock and fix the two locking plates I22 or the two locking plates II23 that are rotated and closed together. like Figs. 1~3As shown, semi-circular insert plates II16 are vertically arranged on the lower left side of the long side of the rear side plate III24 and on the lower right side of the long side of the front side plate III24. Each insert plate II16 is located within the coverage area of the corresponding plate III24 and is integrally formed with the corresponding plate III24. When the two plates III24 are rotated and closed, the two insert plates II16 are attached together, and a pin hole matching the pin shaft II17 is horizontally opened in the middle position. Then, the pin shaft II17 is coaxially inserted into the corresponding pin hole II, thereby locking and fixing the two plates III24 that are rotated and closed together.
[0030] like Figs. 1~3 As shown, a hydraulic cylinder III18 is horizontally arranged on the outer longitudinal side of the upper side bushing 11 located between the clamping plate II23 and the corresponding clamping plate III24. A figure-eight shaped mounting plate is also provided on the left and right sides between the tail of each hydraulic cylinder III18 and the corresponding bushing 11. One end of each mounting plate is coaxially sleeved and fixed on the corresponding bushing 11, and the other end is coaxially sleeved and fixed on the tail of the corresponding hydraulic cylinder III18, thereby fixing the hydraulic cylinder III18 and the corresponding bushing 11 together. The piston rod of each hydraulic cylinder III18 is respectively spaced on the outer side of the corresponding clamping plate III24, and extends horizontally to the right out of the vertical plane where the right side of the corresponding clamping plate III24 is located.
[0031] The hydraulic cylinders I3, II9, and III18 involved in this invention are all existing general-purpose products, and they are all controlled by a controller so that the actions of hydraulic cylinders I3, II9, and III18 can be precisely controlled according to the crimping operation between pipeline 21 and connector 20. This is a conventional control setting for hydraulic cylinders, which is a technology known to those skilled in the industry. Therefore, the principle of how to achieve synchronous hydraulic cylinder actions will not be elaborated here.
[0032] The present invention discloses a crimping method for a crimping machine used for installing flexible composite pipe connectors, such as... Figs. 1~3 Figs. 1~3 As shown, it includes the following steps: Step 1: First, select the corresponding connector 20, connector clamp 5, and outer clamping mold 7 according to the different specifications of flexible composite pipes. Then, divide the connector clamp 5 into three equal parts and embed them coaxially into the corresponding one-third circular groove I, and screw them to the connecting plate I4 or the corresponding clamping plate I22 respectively. Next, divide the outer clamping mold 7 into three equal parts and embed them coaxially into the corresponding one-third circular groove II, and screw them to the connecting plate II6 or the corresponding clamping plate II23 respectively.
[0033] Step 2: Then, the piston rods of the two cylinders I3 extend synchronously, causing the two clamping plates I22, II23, and III24 to rotate and close synchronously. Then, the two clamping plates I22 and II23 are locked and fixed by inserting pin I15, and the two clamping plates III24 are locked and fixed by inserting pin II17.
[0034] Step 3: Then, install the connector 20 coaxially into the connector clamp 5, and extend its clamping end horizontally to the right to the clamp plate II 23.
[0035] Step 4: Then extend the piston rods of the two hydraulic cylinders Ⅲ18 and connect them to the clamps on the pipeline via ropes. At this time, the piston rods of the hydraulic cylinders Ⅲ18 retract, causing the pipeline 21 to coaxially pass through the one-third circular groove Ⅲ and the outer clamping mold 7 to the left, and then coaxially insert into the connector 20.
[0036] Step 5: Then, the piston rods of the three hydraulic cylinders II9 retract synchronously, causing the connector 20 to move horizontally to the right along with the connector clamp 5 until the connector 20 pushes past the outer clamping mold 7 and reaches the designated position, at which point the clamping is completed.
[0037] Step Six: Then, the piston rods of the three hydraulic cylinders II9 extend synchronously, causing the connector clamp 5 to move horizontally to the left along with the connecting plate I4 and the clamping plate I22. Then, the pins I15 and II17 are pulled out. Then, the piston rods of the two hydraulic cylinders I3 retract synchronously, causing the two clamping plates I22, the two clamping plates II23, and the two clamping plates III24 to rotate and open synchronously. At this time, the crimping machine can be lifted and moved to another position by the lifting ring 2 to perform the next crimping operation.
[0038] The beneficial effects of this invention are: (1) The present invention has a simple structure and is easy to operate. By extending or retracting the piston rod of the oil cylinder I3, the two clamping plates I22, two clamping plates II23 and two clamping plates III24 are driven to rotate and close or rotate and open synchronously. Thus, after each clamping is completed, there is no need to disassemble the outer clamping mold 7. This process saves time and effort and improves work efficiency. (2) By setting up a hydraulic cylinder III18 and connecting its piston rod to a clamp on the pipeline via a rope, the piston rod of the hydraulic cylinder III18 can be retracted to drive the pipeline 21 to be coaxially inserted into the connector 20. This process saves time and effort and improves work efficiency. (3) By replacing the connector clamp 5 and the outer clamping mold 7, this invention can be applied to the crimping operation of flexible composite pipe connection joints of different specifications, and has a wide range of applications; (4) By using the fixed shaft 12 and the bushing 11, the present invention can ensure the stability of the horizontal movement of the connecting plate I4 toward the connecting plate II6, thereby ensuring the crimping effect.
