Description

Technical Field

[0001] This invention relates to the field of oilfield production testing technology, and in particular to a well test wire rod lifting device and its working method. Background Technology

[0002] In the daily testing operations of oilfield well testing teams, the use of wirelines is a crucial step. However, due to the special working environment and high operational intensity, wireline wear and replacement have become significant issues. The primary purpose of the wireline is to retrieve testing instruments and tools, requiring it to possess sufficient strength and wear resistance. However, frequent use and operations under extreme conditions result in an average wireline lifespan of only six months. Besides normal wear and tear, the wireline may also need to be replaced prematurely due to sand hole defects or improper twisting during operation.

[0003] The steel wire has a diameter of 2.60 mm, and each reel is 1000 meters, 3000 meters, and 5000 meters long, with corresponding weights of 107 kg, 321 kg, and 515 kg. Because these wire reels are extremely heavy, at least four team members are required to work together to install or replace them. Furthermore, lifting these reels, which weigh several hundred kilograms, not only requires four people to operate simultaneously, but also carries the risk of slipping, undoubtedly posing a safety hazard at the work site and potentially leading to injuries such as being struck by falling steel wire.

[0004] Existing lifting equipment has the following problems: 1. When using portable lifting equipment to lift steel wire, there is a lack of fixation for the steel wire reel; 2. When using large lifting equipment to lift the steel wire reel, the footprint is large and the production cost is high. Summary of the Invention

[0005] (a) Technical problems to be solved This invention provides a well test wire rope reel lifting device and its working method to overcome the problems of existing technologies, such as the lack of a special design for fixing the wire rope reel in the lifting device, which makes it unsuitable for lifting wire rope reels; and the complex structure, high production cost, and large footprint of large lifting equipment, which make it unsuitable for wire rope reels.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides a well test wire rope reel lifting device, comprising: a platform, a triangular fixing bracket, and a base; The base has a platform and a rotating platform at its upper end. The base is connected to the platform by several pillars. The rotating platform is located on the right side of the platform. A rotating shaft is provided between the platform and the rotating platform. The rotating platform is provided with symmetrical support columns on both sides, and a rotating clamp and a fixed clamp are respectively provided on the two support columns. The base is equipped with a lifting mechanism and a transmission mechanism; The lower end of the rotating platform is provided with a guide groove, which is a hollow rectangular structure and limits the lifting mechanism. The base is provided with several transmission rod fixing seats, and the transmission mechanism is limited by the transmission rod fixing seats; A triangular fixing bracket is provided on one side of the platform, and several limiting strips are provided on the triangular fixing bracket, the platform, and the rotating platform respectively. The triangular fixing bracket is integrated with the platform.

[0007] Preferably, the upper end of the rotating platform is provided with two anti-roll limit strips, which are arranged parallel to each other on the rotating platform, and the two anti-roll limit strips limit the movement of the wire reel.

[0008] Preferably, the rotating clamp consists of two parts: one end is a frustum-shaped structure and the other end is a cylindrical structure, with the cylindrical structure embedded in the support column.

[0009] Preferably, one end of the cylindrical structure of the rotating clamp is provided with an external thread, and the outer wall of the cylindrical structure is provided with a through rotating handle.

[0010] Preferably, the rotating shaft is mounted on the base, and the rotating platform is rotatably connected to the rotating shaft.

[0011] Preferably, the lifting mechanism includes: a lifting device, a lifting rocker arm, and guide wheels; The lifting device is mounted on the base and is connected to the lifting rocker arm. One end of the lifting rocker arm is rotatably connected to the lifting device, and the other end is provided with a guide wheel, which is located in a guide groove.

[0012] Preferably, the transmission mechanism includes: transmission rod A, transmission rod B, universal joint, and handwheel; The transmission rod B is embedded in the lifting device. The right end of the transmission rod B is connected to a universal joint. The transmission rod B is connected to the transmission rod A through the universal joint. The right end of the transmission rod A is provided with a handwheel.

[0013] Preferably, transmission rod A and transmission rod B are respectively limited by transmission rod fixing seats, and transmission rod A and transmission rod B can rotate under the control of a handwheel.

[0014] Preferably, the lifting device is a worm gear transmission device, which can rotate the lifting rocker arm by turning the handwheel.

[0015] Preferably, the rotating clamp is rotatable on the support column.

[0016] On the other hand, the present invention also provides a method for operating the device, including: Step S1: Fix the base of the well test wire rope lifting device to the ground with bolts to ensure the stability and safety of the entire device; Step S2: Place the wire reel on the front end of the triangular fixing bracket, roll the wire reel to place it on the rotating platform through the triangular fixing bracket and the platform in sequence, and limit it with the anti-roll limit strip to ensure the stability and safety of the wire reel during the rotation of the rotating platform; Step S3: By rotating the handwheel, the transmission rod B, transmission rod A and universal joint are driven. At the same time, the universal joint rotates and drives the lifting rocker arm through the lifting device to lift the rotating platform upward. Step S4: When the center of the wire reel placed on the rotating platform is aligned with the fixed clamp, stop rotating the handwheel to ensure that the center of the wire reel is accurately aligned with the fixed clamp for subsequent clamping operations. Step S5: Rotate the gripper by turning the handle to secure the wire reel to the fixed gripper; Step S6: When the wire reel is clamped on the rotating clamp and the fixed clamp, turn the handwheel in the opposite direction to lower the rotating platform, ensuring that the rotating platform descends slowly to avoid damage to the wire reel or injury to the operator due to excessive descent speed. Step S7: Replace the wire on the wire reel. After replacement, turn the handwheel. When the rotating platform contacts the wire reel, release the rotating clamp so that the wire reel falls onto the rotating platform. Ensure that the wire reel falls smoothly and avoid damage to the wire reel or rotating platform due to impact.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it is necessary to understand that the orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "inner," "outer," "top," and "bottom" are based on the orientations or positional relationships shown in the accompanying drawings. They are intended only to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the components referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] like Figure 1-4 As shown, the present invention provides a well test wire reel lifting device, comprising: a platform 1, a triangular fixing bracket 5, and a base 10; The base 10 has a platform 1 and a rotating platform 11 on its upper end. The base 10 is connected to the platform 1 by several pillars. These pillars not only provide stable support, but also ensure the safety of the platform 1 during use. The rotating platform 11 is located on the right side of the platform 1. A rotating shaft 16 is provided between the platform 1 and the rotating platform 11. The rotating shaft 16 is located on the base 10. The rotating platform 11 is rotatably connected to the rotating shaft 16. The platform 1 is equipped with a triangular fixing bracket 5 on one side. The triangular fixing bracket 5 is integrated with the platform 1 to form a stable structure. The triangular fixing bracket 5 is a triangular ramp on one side of the platform 1. The main function of the triangular fixing bracket 5 is to serve as a channel for the rolling of the wire reel. The triangular fixing bracket 5 provides a ramp that facilitates rolling, which greatly reduces the labor intensity of the operators and improves work efficiency. The triangular fixed bracket 5, platform 1, and rotating platform 11 are each provided with a number of limiting strips 6. The limiting strips 6 are respectively located on both sides of the triangular fixed bracket 5, platform 1, and rotating platform 11. The limiting strips 6 prevent the wire reel from slipping off the triangular fixed bracket 5, platform 1, and rotating platform 11 when it is rolling. The design of the limiting strips 6 effectively prevents the wire reel from slipping off due to accidents during the movement, ensuring the safety and reliability of the operation.

[0023] The rotating platform 11 has symmetrical support columns 7 on both sides. A rotating clamp 4 and a fixed clamp 3 are respectively mounted on the two support columns 7. The rotating clamp 4 consists of two parts: a frustum-shaped structure at one end and a cylindrical structure at the other. The fixed clamp 3 also consists of two parts: a frustum-shaped structure at one end and a cylindrical structure at the other. The fixed clamp 3 is fixed to the support column 7, and the cylindrical structure is embedded in the support column 7. One end of the cylindrical structure of the rotating clamp 4 has an external thread. By rotating the threaded cylindrical structure, the position of the rotating clamp 4 can be adjusted to accommodate wire reels of different diameters. The outer wall of the cylindrical structure has a through-hole rotating handle 8. By rotating the handle 8, the operator can more easily adjust the position of the rotating clamp 4, improving the convenience and efficiency of operation.

[0024] The base 10 is equipped with a lifting mechanism and a transmission mechanism. Several transmission rod fixing seats 18 are installed on the base 10. These fixing seats are used to limit and position the transmission mechanism to ensure the stability and reliability of the transmission mechanism during operation. The transmission mechanism consists of transmission rod A13, transmission rod B14, universal joint 15, and handwheel 9. Transmission rod B14 is embedded in the lifting device 17, and its right end is connected to a universal joint 15, which in turn connects to transmission rod A13. A handwheel 9 is installed on the right end of transmission rod A13. The operator can drive transmission rod A13 and transmission rod B14 to rotate by turning the handwheel 9. Transmission rod A13 and transmission rod B14 are respectively limited by transmission rod fixing seat 18 to ensure their smoothness and accuracy during rotation. The lifting mechanism includes a lifting device 17, a lifting rocker arm 12, and a guide wheel. The lifting device 17 is mounted on the base 10 and connected to the lifting rocker arm 12. One end of the lifting rocker arm 12 is rotatably connected to the lifting device 17, and the other end is equipped with a guide wheel. This guide wheel is located in the guide groove 19 at the lower end of the rotating platform 11. The guide groove 19 is a hollow rectangular structure, and its function is to restrict and guide the movement of the lifting mechanism to ensure the stability and accuracy of the lifting mechanism during operation. The lifting device 17 adopts a worm gear transmission device. By turning the handwheel 9, the lifting rocker arm 12 can be driven to rotate, thereby realizing the lifting function. With this design, the operator can control the movement of the transmission mechanism and the lifting mechanism by turning the handwheel 9, so as to realize the rotation function of the rotating platform 11, which reduces the labor intensity of the operator and improves work efficiency and safety.

[0025] The lower end of the rotating platform 11 is equipped with a guide groove 19, which is a hollow rectangular structure. Its main function is to limit and guide the lifting mechanism, ensuring the stability and accuracy of the lifting mechanism during operation. The guide groove 19 effectively restricts the movement trajectory of the lifting mechanism, preventing the lifting mechanism from deviating or shaking during operation, and improving the reliability and safety of the entire device. At the upper end of the rotating platform 11, two anti-roll limit strips 2 are installed, which are arranged parallel to each other on the rotating platform 11. Their main function is to limit the wire reel placed on the rotating platform 11, preventing the wire reel from rolling or sliding on the rotating platform 11. By setting these two anti-roll limit strips 2, the stability and safety of the wire reel on the rotating platform 11 can be ensured, avoiding the wire reel from accidentally slipping off during the rotation of the rotating platform 11, thus improving the safety and reliability of operation.

[0026] The following is a detailed description of the actual working scenario of a well test wire rope lifting device.

[0027] like Figure 5 As shown, the present invention provides a method for operating a well test wire rope reel lifting device, comprising: Step S1: Fix the base 10 of the well test wire rope lifting device to the ground with bolts to ensure the stability and safety of the entire device; Step S2: Place the wire reel at the front end of the triangular fixing bracket 5, and roll the wire reel to place it on the rotating platform 11 through the triangular fixing bracket 5 and platform 1 in sequence. The anti-roll limit strip 2 limits the wire reel to ensure the stability and safety of the wire reel during the rotation of the rotating platform 11. Step S3: By rotating the handwheel 9, the transmission rod B14, transmission rod A13 and universal joint 15 are driven. As the universal joint 15 rotates, the lifting device 17 drives the lifting rocker arm 12 to lift the rotating platform 11 upward. Step S4: When the center of the wire reel placed on the rotating platform 11 is aligned with the fixed clamp 3, stop rotating the handwheel 9 to ensure that the center of the wire reel is accurately aligned with the fixed clamp 3 for subsequent clamping operations. Step S5: Rotate the handle 8 to rotate the clamp 4, so that the rotating clamp 4 and the fixed clamp 3 are fastened together. Step S6: When the wire reel is clamped on the rotating clamp 4 and the fixed clamp 3, turn the handwheel 9 in the opposite direction to lower the rotating platform 11, ensuring that the rotating platform 11 descends slowly to avoid damage to the wire reel or injury to the operator due to excessive descent speed. Step S7: Replace the wire on the wire reel. After replacement, turn the handwheel 9. When the rotating platform 11 contacts the wire reel, release the rotating clamp 4 so that the wire reel falls onto the rotating platform 11. Ensure that the wire reel falls smoothly and avoid damage to the wire reel or the rotating platform 11 due to impact.
