Description

Technical Field

[0001] This invention relates to the field of cable processing equipment for oil exploration, and in particular to a lifting ring injection molding equipment. Background Technology

[0002] Before using seismic detector strings for field exploration, the strings required pins to be threaded through lifting rings and connected to cables for suspension, lifting, winding, and unwinding. Currently, the lifting rings used to connect the cables are typically manufactured separately using molding / injection molding processes, resulting in a completely separate structure from the cable. The connection between the lifting ring and the cable relies entirely on manual installation. Specifically, the separately manufactured rubber lifting ring is manually wrapped around and placed at the designated position on the cable, and then manually secured to connect the ring and the cable. This separate lifting ring manufacturing method is cumbersome and has low production and assembly efficiency. Furthermore, during actual exploration operations, the separate lifting ring structure cannot withstand the bumps, pulling, and outdoor environmental corrosion of the exploration site, easily leading to loosening and detachment of the connection with the cable. This affects the service life of both the cable and the lifting ring, and cannot guarantee the reliability of the seismic detector string connection under complex field conditions. Summary of the Invention

[0003] The purpose of this invention is to provide a lifting ring injection molding equipment to solve the technical problems mentioned in the background section.

[0008] Furthermore, a wire feeding mechanism is provided at one end of the traction platform near the take-up device. The wire feeding mechanism includes a mounting base fixedly mounted at the end of the traction platform. Two vertical second lifting cylinders are symmetrically fixedly mounted on the mounting base. The telescopic ends of the two second lifting cylinders are jointly fixedly connected to the wire feeding frame. Multiple vertical wire feeding guide rollers are rotatably mounted at one end of the wire feeding frame, and two parallel wire feeding transverse guide rollers are rotatably mounted at the other end of the wire feeding frame.

[0009] Furthermore, a mounting plate is fixedly installed at one end of the traction table near the injection molding machine, and two horizontal guide rods are symmetrically fixed between the mounting plate and the mounting base.

The one-piece injection-molded lifting rings can directly and firmly bond with the cables, replacing the original separate installation method. This avoids the loosening and detachment problems associated with manual installation, ensuring the reliability of the geophone string connection under complex field conditions. It also eliminates the need for manual winding and fixing, improving construction and assembly efficiency. Simultaneously, the integrated injection-molded structure enhances the sealing and tensile strength of the lifting ring and cable, adapting to the bumps, pulls, and outdoor environmental corrosion of the exploration site, extending the service life of the cable and lifting ring, and meeting the practicality and durability requirements of seismic exploration operations for related components.

This creates a fully automated cable lifting ring injection molding production line, from unloading and injection molding to reloading. During production, lifting, traction, and positioning are completed without manual intervention. Cable tension is controllable, guidance is precise, and positioning is reliable. Furthermore, multiple lines operate in parallel with a compact cycle time, allowing for simultaneous injection molding of multiple cables, meeting the large-scale production needs of oil exploration cables. Therefore, this invention effectively solves the problems of high reliance on manual labor, poor continuity, and low efficiency in the processing and assembly of cable lifting rings in existing technologies, demonstrating clear industrial practical value and promising prospects for widespread application.

[0017] like Figures 1-7 As shown, a lifting ring injection molding equipment includes a cable feeding device, an injection molding device, and a cable take-up device arranged in sequence; the cable feeding device is used to feed the cable to be injected into the lifting ring to the injection molding device, and the cable take-up device is used to wind up the cable after the lifting ring injection molding is completed by the injection molding device.

[0018] The injection molding device includes an injection molding machine 1 and a traction table 2 disposed between the injection molding machine 1 and the take-up device. A lower mold 3 is fixedly installed on the upper part of the table of the injection molding machine 1. An upper mold 4 adapted to the lower mold 3 is slidably installed on the injection molding machine 1 above the lower mold 3. Two mold opening cylinders 5 for driving the upper mold 4 to move up and down are symmetrically fixedly installed on the top of the injection molding machine 1. Multiple molding grooves adapted to the lifting ring to be injected are opened at the opposite ends of the lower mold 3 and the upper mold 4, and multiple cable passage holes 6 are opened between the two ends of the lower mold 3 and the upper mold 4. In this embodiment, the number of cable passage holes 6 is four. The injection molding machine 1 in this embodiment has the same working principle as the injection molding machine in the prior art, so its specific structural features will not be described in detail in this specification.

[0019] As an improvement, the table of the injection molding machine 1 is provided with a wire feeding mechanism at one end near the wire feeding device. The wire feeding mechanism includes a wire feeding frame 7 fixedly installed at the end of the table of the injection molding machine 1 and a plurality of wire feeding vertical guide rollers 8 rotatably installed between the wire feeding frame 7 and the lower mold 3. Two parallel wire feeding horizontal guide rollers 9 are rotatably installed on the wire feeding frame 7. The two wire feeding horizontal guide rollers 9 and the plurality of wire feeding vertical guide rollers 8 can limit and guide the wire fed by the wire feeding device in both horizontal and vertical directions, so that the wire smoothly enters the wire passage hole 6 on the mold.

[0020] A traction seat 10 is horizontally slidably mounted on the traction platform 2. Two first lifting cylinders 11 are fixedly mounted on the bottom of the traction seat 10. The telescopic ends of the two first lifting cylinders 11 are fixedly connected to the bottom of a clamping seat 12 located above the traction seat 10. A cable clamping mechanism is provided on the clamping seat 12. In this embodiment, a sliding groove 13 is formed on the upper surface of the clamping seat 12. The cable clamping mechanism includes a plurality of fixed clamping blocks 14 fixedly mounted at intervals above the sliding groove 13 and a plurality of sliding clamping blocks 15 slidably mounted in the sliding groove 13 and corresponding one-to-one with each of the fixed clamping blocks 14. The portions of two adjacent sliding clamping blocks 15 located inside the sliding groove 13 are fixedly connected. A horizontal clamping cylinder 16 is fixedly mounted on the side of the clamping seat 12. The telescopic end of the clamping cylinder 16 extends into the interior of the clamping seat 12 and is fixedly connected to the sliding clamping block 15 located at the end. The four cables that have completed the injection molding of the lifting ring pass through the corresponding fixed clamping blocks 14 and sliding clamping blocks 15 on the clamping seat. After the clamping cylinder 16 extends, the sliding clamping block 15 and the fixed clamping block 14 clamp the cables together. Then, the two first lifting cylinders 11 extend synchronously, so that the clamping seat 12 moves upward and lifts the cables upward, so that the lifting ring that has completed injection molding in the injection molding machine is separated from the molding groove in the mold. The traction seat 10 slides linearly on the traction table 2, thereby pulling the cables to move towards the take-up device.

[0021] A cable delivery mechanism is provided at one end of the traction platform 2 near the take-up device. The cable delivery mechanism includes a mounting base 17 fixedly installed at the end of the traction platform 2. Two vertical second lifting cylinders 18 are symmetrically fixedly installed on the mounting base 17. The telescopic ends of the two second lifting cylinders 18 are fixedly connected to the cable delivery frame 19. Multiple vertical cable delivery guide rollers 20 are rotatably installed at one end of the cable delivery frame 19, and two parallel cable delivery horizontal guide rollers 21 are rotatably installed at the other end of the cable delivery frame 19. The multiple vertical cable delivery guide rollers 20 and the multiple horizontal cable delivery guide rollers 21 can respectively guide and limit the cable released from the injection molding machine in the vertical and horizontal directions, so that the cable is smoothly transported to the take-up device. When the two first lifting cylinders 11 extend, the two second lifting cylinders 18 extend synchronously, causing the mounting base 17 to move upward. The two horizontal cable delivery guide rollers 21 cooperate with the clamping seat 12 to lift the cable.

[0022] A mounting plate 22 is fixedly installed at one end of the traction platform 2 near the injection molding machine 1. Two horizontal guide rods 23 are symmetrically fixedly installed between the mounting plate 22 and the mounting base 17. Two guide sleeves 24, which are symmetrically fixedly installed at the bottom of the traction base 10 and respectively slide with the two horizontal guide rods 23, thereby realizing the sliding installation of the traction base 10 on the traction platform 2. A first driven sprocket 25 is rotatably installed between the two horizontal guide rods 23 on the mounting base 17. A second driven sprocket 26 is rotatably installed between the two horizontal guide rods 23 on the mounting plate 22. A driving sprocket 26 is rotatably installed at the bottom of the traction platform 2, and a traction motor 28 for driving the driving sprocket 27 to rotate is fixedly installed thereon. A traction chain 29 is wound around the driving sprocket 27, the first driven sprocket 25, and the second driven sprocket 26. The front and rear ends of the traction base 10 are respectively fixedly connected to the two ends of the traction chain 29. When the traction motor 28 drives the drive sprocket 27 to rotate in the forward direction, the drive sprocket 27, The chain drive mechanism, consisting of the first driven sprocket 25, the second driven sprocket 26, and the traction chain 29, causes the traction chain 29 to drive the traction seat 10 to move towards the mounting seat 17. That is, the traction seat 10 pulls the cable a certain distance towards the take-up device. When the designated position is reached, the clamping cylinder 16, the two first lifting cylinders 11, and the two second lifting cylinders 18 retract and reset. The traction motor 28 drives the drive sprocket 27 to rotate in the opposite direction, causing the traction seat 10 to move and reset towards the injection molding machine. The injection molding machine 1 then performs the next lifting ring injection molding process on the cable. This cycle is repeated to achieve automatic and continuous lifting ring injection molding operations on the entire cable.

[0023] The wire feeding device includes multiple wire feeding frames 30, the same number as the cable passage holes 6. Each wire feeding frame 30 is rotatably mounted with a wire feeding shaft 31 for mounting a wire spool. Each wire feeding frame 30 is rotatably mounted with a wire feeding drive shaft 32 on its side. One end of the wire feeding drive shaft 32 is connected to the output end of a wire feeding reducer 33 fixedly mounted on the outside of the wire feeding frame 30. A wire feeding motor 34 is mounted on the input end of the wire feeding reducer 33. The other end of the wire feeding drive shaft 32 is connected to the wire feeding shaft 31 by belt drive. After the wire feeding motor 34 is started, it causes the wire feeding shaft 31 to rotate, feeding the cable to be injected with the lifting ring on the wire spool toward the injection molding machine.

[0024] The take-up device includes multiple take-up frames 35, the same number as the cable passage holes 6. Each take-up frame 35 is rotatably mounted with a take-up shaft 36 for mounting a cable spool. Each take-up frame 35 is rotatably mounted with a take-up drive shaft 37 on its side. One end of the take-up drive shaft 37 is connected to the output end of a take-up reducer 38 fixedly mounted on the outside of the take-up frame 35. A take-up motor 39 is mounted on the input end of the take-up reducer 38. The other end of the take-up drive shaft 37 is connected to the take-up shaft 36 via belt drive. When the take-up motor 39 is started, it causes the take-up shaft 36 to rotate, winding the cable with the lifting ring injection molded onto the cable spool of the take-up shaft 36.

[0025] In addition, to ensure cable tension throughout the entire operation, cable storage devices are respectively installed between the cable feeding device and the injection molding device, and between the cable take-up device and the injection molding device. Each cable storage device includes two cable storage racks 40 fixedly installed on the ground. Guide wheels 41 are rotatably mounted on the upper part and both sides of each cable storage rack 40. Two sets of vertical guide rods 42 are vertically and symmetrically fixedly installed inside each cable storage rack 40. Lifting blocks 43 are slidably mounted on the same set of vertical guide rods 42. Cable storage wheels 44 are rotatably mounted on the outer side of each lifting block 43. Upper contact switches 45 are fixedly installed above the two lifting blocks 43 on the lower part of the cable storage rack 40 below the two guide wheels 41 on one side of the rack. Lower contact switches 46 are fixedly installed below the two lifting blocks 43 on the lower part of the cable storage rack 40.

[0026] The cable fed by the cable feeding device to the injection molding device passes sequentially through the guide wheel 41 on the upper part of the corresponding cable storage rack 40, the guide wheel 41 near the cable feeding device, the cable storage wheel 44, and the guide wheel 41 near the injection molding machine. During the cable feeding process, the cable storage wheel 44 will drive the cable downward under the gravity of the lifting block 43, thereby ensuring the tension during the cable feeding process and reserving the cable passage length required for the next lifting ring injection. When the lifting block 43 contacts the lower contact switch 46, the corresponding cable feeding motor 34 stops feeding. After the injection molding machine completes the lifting ring injection process on the part of the cable located in the mold, the traction seat 10 pulls the cable towards the take-up device. During this process, the cable pulls the lifting block 43 and the cable storage wheel 44 upward. When the lifting block 43 contacts the upper contact switch 45, the cable is pulled by the traction seat 10 to the part in the mold for the next lifting ring injection position. The traction seat 10 quickly returns to its original position and clamps the cable through the cable clamping mechanism. At this time, the cable feeding motor starts again to feed the cable. The cable storage rack 40 performs the above actions again to reserve the cable passage length required for the next lifting ring injection. This cycle is repeated to realize the automatic adjustment of cable tension and operation reserve during the cable feeding process.

[0027] Conversely, the cable wound by the take-up device, processed by the injection molding device, corresponds sequentially to the guide roller 41 on the upper part of the cable storage rack 40, the guide roller 41 near the injection molding machine, the cable storage roller 44, and the guide roller 41 near the take-up device. During the cable winding process, the cable moving towards the take-up device pulls the lifting block 43 and the cable storage roller 44 upwards until the lifting block 43 contacts the upper contact switch 45, at which point the take-up motor 39 stops winding. After the injection molding machine completes the lifting ring injection processing of the part of the cable in the mold, the traction seat 10 pulls the cable towards the take-up device. Under the gravity of the lifting block 43, the cable storage roller 44 drives the cable downwards, thus ensuring the tension of the cable released by the injection molding device. When the lifting block 43 contacts the lower contact switch 46, the take-up motor starts again to perform the take-up operation. This cycle achieves automatic adjustment of cable tension during the take-up process.
