Description

Technical Field

[0001] This utility model belongs to the technical field of oil well workover equipment, specifically relating to a wire rope drive fixing device and a well workover tubing delivery device. Background Technology

[0002] In oilfield well workover operations, tubing needs to be transported back and forth between the pipe rack and the wellhead. Traditional tubing transport relies entirely on manual operation: when running the tubing down, workers push the tubing onto a simple pulley and then push the pulley to the wellhead. After the wellhead clamps engage the tubing and lift it up, the pulley moves forward with the tubing string. After the tubing detaches, the pulley must be manually pulled back to the starting position. When pulling the tubing up, the empty pulley must be manually pushed to the wellhead to catch the end of the tubing. After the end of the tubing falls into the pulley, the clamps are lowered, and the pulley moves back to the starting position. The tubing must then be manually removed from the pulley. This manual transport method suffers from high labor intensity, low efficiency, and significant safety hazards, especially in deep wells and heavy tubing operations. To avoid the problems of traditional manual transport, electric motors are now used instead of manual labor. However, the wire rope is prone to slack, leading to traction failure. Furthermore, the single-drum design requires frequent starting and stopping of the motor during tubing lifting and lowering, resulting in high energy consumption and rapid wire rope wear.

[0003] Existing technologies include research on automated tubing transport, such as patent CN220151298U - tubing transport device for well workover, which uses a double-cylinder hydraulic winch to drive a wire rope traction pulley. Although this reduces the burden of manpower, the hydraulic system has problems such as the risk of oil leakage and pollution, high noise, and complex maintenance. In addition, it needs to rely on an external hydraulic power source, which limits its adaptability to the field. Patent CN220353834U - automatic tubing transport device for well workover operations, which realizes tubing transport through a slide rail, motor and hydraulic hook device, but requires the laying of fixed tracks, has poor deployment flexibility, is difficult to adapt to complex well site terrain, and the hook mechanism has a complex structure and a high failure rate.

[0004] In summary, while existing pipeline conveying systems have made progress in reducing manpower requirements, they still generally face core problems such as power system issues, structural complexity, poor deployment flexibility, inefficient integration of automated processes, and consequently, high maintenance costs and potential safety risks. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0005] The purpose of this utility model is to provide a wire rope driven fixing device and a well workover tubing delivery device to solve the core problems mentioned in the background art, such as the power system, structural complexity, poor deployment flexibility, unsmooth connection of automated processes, and the resulting high maintenance costs and potential safety risks that current tubing delivery devices generally face.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire rope drive and fixing device, comprising a base frame with lifting lugs and a wire rope drum assembly fixed on the base frame. The wire rope drum assembly has a side from which the wire rope extends, defined as the rope outlet side. An adjusting rod is vertically fixed to the base frame on the rope outlet side. A horizontally extending guide rail is mounted on the adjusting rod. Two guide pulleys are slidably mounted on the guide rail. A cable drum assembly is located on the side of the wire rope drum assembly opposite to the rope outlet side. The assembly includes a roller, one end of which is supported on a base frame by a bearing and the other end of which is fixedly mounted with a handwheel. The cable roller assembly is fixed on the base frame. Each end of the base frame has a fixing pin on one side where an adjusting rod is fixed. The other side of the base frame opposite to the side where the adjusting rod is fixed has a cable connected to a tensioning pin. An electrical control mounting frame is fixed on the base frame near the drive end of the wire rope roller assembly. An electrical control box is mounted on the electrical control mounting frame and is connected to the wire rope roller assembly and the cable roller assembly via a cable.

[0007] Furthermore, the wire rope drum assembly includes a forward winding drum for forward winding of the wire rope, a reverse winding drum for reverse winding of the wire rope, and a servo motor. The output end of the servo motor is connected to a drive shaft, which passes through the center of the reverse winding drum and the forward winding drum in sequence. The reverse winding drum and the forward winding drum are fixed side by side on a fixed frame provided in the middle area of ​​the base frame. A rope presser is provided at the rope exit position of the reverse winding drum and the rope exit position of the forward winding drum. A crossbar is provided at the top of the fixed frame at the rope exit positions of the reverse winding drum and the forward winding drum, and the two rope pressers are slidably sleeved on the corresponding crossbars.

[0008] Furthermore, the end of the drive shaft near the servo motor is fixedly connected to the reverse winding roller; the end of the drive shaft away from the servo motor is provided with an axial hole, and the forward winding roller is detachably connected to the drive shaft through a clutch pin that can be inserted into the axial hole; the outer wall of the fixing frame near the end of the forward winding roller is provided with a pin holder for storing the clutch pin.

[0009] Furthermore, the positions of the two guide pulleys correspond to the wire rope exit directions of the forward-winding drum and the reverse-winding drum, respectively. One guide pulley is slidably mounted on the guide rail frame at a position corresponding to the wire rope exit direction of the forward-winding drum, and the other guide pulley is slidably mounted on the guide rail frame at a position corresponding to the wire rope exit direction of the reverse-winding drum.

[0010] In addition to the above technical solutions, there is also a workover tubing delivery device with the wire rope drive fixing device. The workover tubing delivery device also includes a derrick, a pulley assembly fixed on the derrick, and a hook pulley assembly. The hook pulley assembly is hooked onto a wire rope led out by the wire rope drive fixing device. The wire rope has a rope clamp in the section between the derrick and the hook pulley assembly. The wire rope passes around the pulley assembly.

[0011] Furthermore, the hook-tube pulley assembly includes a pulley seat and a hook. The upper end of the hook is rotatably connected to the pulley seat and the lower end of the hook is provided with a hook portion for hooking the oil pipe. The side of the hook is provided with an operating handle. A hanging pulley is installed on the pulley seat and the hanging pulley is slidably hooked onto the wire rope.

[0012] Furthermore, the pulley assembly includes a shift fork fixing plate and a derrick pulley seat. The derrick pulley seat is hinged to the bottom of the shift fork fixing plate, and a pulley is installed on the derrick pulley seat. Each end of the shift fork fixing plate is threaded with a fastening bolt for fixing the shift fork fixing plate to the derrick. The top of the shift fork fixing plate is threaded with a limit bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model adopts a modular design concept, independently designing and fixing key components such as the wire rope drum assembly, cable drum assembly, and electrical control system onto the base frame. This reduces the coupling between components, facilitating individual replacement and maintenance, thereby significantly enhancing the adaptability and maintainability of the equipment, reducing maintenance costs and downtime. By installing an adjusting rod vertically fixed to the base frame on the rope outlet side of the wire rope drum assembly, and mounting a horizontally extending guide rail and sliding guide pulley on the adjusting rod, precise guidance and tension control of the wire rope are achieved. This ensures that the wire rope remains taut throughout the conveying process, preventing slack and deviation, thus significantly improving operational stability and safety. Based on this, an electrical control box is used... The all-electric drive system enables integrated electrical control of the wire rope drum assembly and cable drum assembly, allowing operators to remotely control the equipment via the control box. This also effectively avoids oil leakage and pollution problems caused by the hydraulic system, reduces working noise, improves the working environment, and simplifies the maintenance of the electrical control system. It greatly improves the convenience of operation and the smoothness of automation, reducing the need for manual intervention. Through careful design of the base frame and the layout of each component, as well as the lifting lugs with overall convenient transportation design elements, the equipment achieves a high degree of compactness. This allows the equipment to maintain high performance while also having good transportation convenience, enabling rapid deployment to various well site environments and improving the flexibility and adaptability of the equipment.

[0015] 2. This utility model uses a servo motor to drive the transmission shaft, causing the forward and reverse winding double drums to rotate synchronously. This ensures that the wire rope remains taut during the lifting or lowering of the tubing, completely eliminating the risk of traction failure caused by slack in a single drum. This allows for continuous lifting and lowering of the tubing, reduces the number of motor start-stop cycles, achieves efficient energy management, and extends the service life of the wire rope. It also significantly improves operational efficiency and flexibility. Furthermore, a clutch pin controls the engagement and disengagement of the forward winding drum and the transmission shaft, allowing the forward winding drum to rotate freely without the servo motor's drive. This enables the workover equipment to quickly adjust the wire rope's condition when malfunctions occur or when the workover is completed, without disassembling the entire drum assembly. This simplifies the operation process, reduces maintenance costs and time, and significantly improves the reliability of the workover equipment. A sliding rope presser, fixed to the frame by a corresponding crossbar, is installed at the rope exit position of both the forward and reverse winding drums. This ensures that the wire rope remains taut and orderly arranged during drum rotation, preventing tangling and improving the stability and safety of the equipment.

[0016] 3. This utility model, by positioning two guide pulleys corresponding to the wire rope output directions of the forward and reverse winding drums respectively, and slidably mounting them on the guide rail frame, allows for precise control of the wire rope output direction by adjusting the position of the guide pulleys according to actual working needs. This effectively reduces wire rope wear and vibration, and improves the service life and operating efficiency of the wire rope. The design of the fixing pin and cable connection tension pin achieves stable fixation and flexible adjustment of the base frame, enabling the equipment to adapt to different terrains and derrick sizes, improving its adaptability and stability, and maintaining efficient operation even in complex well site environments. The drums in the cable drum assembly are supported by bearings and have fixed handwheels, allowing operators to manually rotate the drums when needed, facilitating cable winding and management, and improving the convenience and safety of cable management.

[0017] 4. This utility model integrates the wire rope drive fixing device with the derrick, pulley assembly, and hook pulley assembly into a well workover tubing delivery device, realizing fully automated tubing delivery between the tubing rack and the wellhead. This effectively reduces manual intervention, improves the safety and accuracy of operations, and reduces labor intensity and costs. By using rope clips on the wire rope and a rotatable hook with an operating handle on the hook pulley assembly, the safe hooking and stable operation of the tubing during delivery are ensured, effectively preventing tubing from falling off or being damaged, thus improving the safety and reliability of operations. The modular design of the pulley assembly, using a fork fixing plate and derrick pulley seat, allows the pulley assembly to be fixed to the derrick with fastening bolts and limit bolts, facilitating quick installation and adjustment of the pulley assembly. This adapts to different derrick sizes and operational requirements, improving the equipment's versatility and flexibility. Attached Figure Description

The output end of the servo motor 203 is connected to a drive shaft 7. The drive shaft 7 passes through the center of the reverse winding drum 202 and the forward winding drum 201 in sequence. The reverse winding drum 202 and the forward winding drum 201 are fixed side by side on a fixed frame 8 set in the middle area of ​​the base frame 1. A rope presser 9 is set at the rope exit position of the reverse winding drum 202 and the rope exit position of the forward winding drum 201. A crossbar 801 is set at the top of the fixed frame 8 at the rope exit positions of the reverse winding drum 202 and the forward winding drum 201, respectively. The two rope pressers 9 are slidably sleeved on the corresponding crossbar 801.

[0032] The positions of the two guide pulleys 6 correspond to the rope exit directions of the wire rope 3 of the forward winding drum 201 and the reverse winding drum 202, respectively.

[0036] Please see Figures 7-10 This embodiment provides a well workover tubing delivery device, including the wire rope drive and fixing device in embodiment 1. Therefore, the well workover tubing delivery device can obtain any of the beneficial effects of the wire rope drive and fixing device described above, which will not be repeated here.

[0037] In addition to the wire rope drive and fixing device in Embodiment 1, it also includes a derrick 18, a pulley assembly 19 fixed on the derrick 18, and a hook pipe pulley assembly 20. The hook pipe pulley assembly 20 is hooked onto the wire rope 3 led out by the wire rope drive and fixing device. The wire rope 3 is provided with a rope clip 21 in the section between the derrick 18 and the hook pipe pulley assembly 20 to realize the positioning of the hook pipe pulley assembly 20. The wire rope 3 passes through the pulley assembly 19.

[0038] The hook-tube pulley assembly 20 includes a pulley seat 2001 and a hook 2002. The upper end of the hook 2002 is rotatably connected to the pulley seat 2001 and the lower end of the hook is provided with a hook for hooking the oil pipe 25. The side of the hook 2002 is provided with an operating handle 22. A hanging pulley 2003 is installed on the pulley seat 2001 and the hanging pulley 2003 is slidably hooked onto the wire rope 3.

The derrick pulley seat 1902 is hinged to the bottom of the shift fork fixing plate 1901, which can always keep the force direction of the oil pipe 25 consistent with the movement direction. A pulley 1903 is installed on the derrick pulley seat 1902.

Different sizes of derricks can be fixed by adjusting the fastening bolts 23, and it can be quickly and firmly connected to the derrick 18. The top of the shift fork fixing plate 1901 is threaded with a limit bolt 24.

[0040] Based on the wire rope drive fixing device and well workover tubing delivery equipment described in Embodiments 1 and 2 above, the working principle and usage process of this utility model are as follows: Figures 1-10 As shown, after the steel wire rope drive fixing device is assembled, the operator will install the entire device on the well workover tubing delivery equipment. The purpose is to realize the fully automated delivery of tubing 25 between the tubing rack 26 and the wellhead, effectively reducing manual intervention, improving the safety and accuracy of the operation, and reducing labor intensity and cost, thereby ensuring overall work efficiency.

[0041] When tubing 25 needs to be lowered, the operator must first arrange the tubing 25 for well workover on the tubing rack 26. Then, the base frame 1 of the wire rope drive fixing device is fixed to the tail end of the tubing rack 26 by the fixing pin 102 and the tensioning pin 104. Then, one end of the wire rope 3 is wound forward onto the forward winding drum 201, while the other end is wound sequentially around the guide pulley 6 in the direction of the rope exit of the forward winding drum 201, the hanging pulley 2003 of the hook tube pulley assembly 20, the pulley 1903 of the pulley assembly 19, and the corresponding reverse winding pulley. The guide pulley 6 on the rope-out direction of the drum 202 is wound in the opposite direction onto the reverse winding drum 202, so that the hanging pulley 2003 can move as the servo motor 203 drives the wire rope 3 to be wound and unwound under the limit of the rope clamp 21. Then, the hook of the hook 2002 of the hook tube pulley assembly 20 hooks the tail end of an oil pipe 25 in the pipe rack 26. The servo motor 203 is controlled to rotate forward by the remote control operating the control box 17. At this time, the wire rope 3 will rotate forward synchronously under the drive of the servo motor 203 to the forward winding drum 201 and the reverse winding drum 202. The system achieves forward deployment and retraction (i.e., forward winding drum 201 is responsible for releasing the wire rope 3, and reverse winding drum 202 is responsible for retracting the wire rope 3). The hook-and-pipe pulley assembly 20 carries the tubing 25, moving it towards the derrick 18 as the wire rope 3 is deployed and retracted, until the head of the tubing 25 is engaged with the hoist at the wellhead. The tubing 25 is then lifted upwards via the hoist. The servo motor 203 is then controlled to rotate in the reverse direction via the remote control control box 17. At this time, the wire rope 3 rotates synchronously in the opposite direction as the forward winding drum 201 and the reverse winding drum 202 are driven by the servo motor 203. The reverse winding and unwinding mechanism (i.e., the reverse winding drum 202 is responsible for unwinding the wire rope 3, and the forward winding drum 201 is responsible for winding the wire rope 3) forces the rope clamp 21 to move towards the base frame 1 along with the reverse winding and unwinding of the wire rope 3 to the tail of the pipe rack 26 (i.e., the initial position). Meanwhile, the oil pipe 25 on the hook pipe pulley assembly 20 will move along the wire rope 3 to the wellhead under the driving force. The wellhead worker will disengage the hook 2002 from the tail of the oil pipe 25, so that the hanging pulley 2003 can slide along the wire rope 3 by its own weight to the tail of the pipe rack 26 (i.e., the initial position).

[0042] When tubing 25 needs to be pulled up, the operator first uses the remote control to operate the control box 17 to control the servo motor 203 to rotate forward. At this time, the wire rope 3 will be pulled up and down in the forward direction under the synchronous forward rotation of the forward winding drum 201 and the reverse winding drum 202 driven by the servo motor 203 (i.e., the forward winding drum 201 is responsible for releasing the wire rope 3, and the reverse winding drum 202 is responsible for taking in the wire rope 3). The hook pulley assembly 20 located at the tail of the pipe rack 26 will move towards the derrick 18 to the wellhead waiting position as the wire rope 3 is pulled up and down in the forward direction. When the tubing 25 at the wellhead is ready, the tail end of the tubing 25 is lowered into the hook of the hook 2002. Then, the operator uses the remote control to operate the control box 17 to control the servo motor 203 to rotate forward. When the servo motor 203 rotates in the reverse direction, the wire rope 3 will be wound and released in the opposite direction under the synchronous reverse rotation of the forward winding drum 201 and the reverse winding drum 202 driven by the servo motor 203 (that is, the reverse winding drum 202 is responsible for releasing the wire rope 3, and the forward winding drum 201 is responsible for winding the wire rope 3). This forces the rope clamp 21 to move towards the base frame 1 and to the tail of the pipe rack 26 as the wire rope 3 is wound and released in the opposite direction. At the same time, the wellhead hoist will lower the tubing 25. Under its own weight, the tubing 25 will slide towards the base frame 1 with the hook and pipe pulley assembly 20 until it slides to the tail of the pipe rack 26. After the wellhead hoist is removed, the hook 2002 can be detached from the tail end of the tubing 25.

[0043] When the tubing transfer is completed or the workover tubing delivery equipment malfunctions, the operator only needs to pull out the clutch pin 10 and store it on the pin holder 11. This will allow the forward winding drum 201 to be disengaged from the drive of the servo motor 203 and rotate freely. At this time, the wire rope 3 led out from the wire rope drive fixing device will be wound onto the forward winding drum 201 under the free rotation of the forward winding drum 201, or wound onto the reverse winding drum 202 by the drive of the servo motor 203. This prepares for the next tubing 25 transfer or timely maintenance of the workover tubing delivery equipment, ensuring the safety of the workover tubing delivery equipment maintenance.
