Description

Technical Field

[0001] This application belongs to the field of in-situ leaching uranium well site mining technology, specifically relating to a device and method for lifting, lowering and bundling in-situ leaching uranium mining cables. Background Technology

[0002] In-situ leaching is an important uranium mining technology. Compared to traditional open-pit or underground mining, it involves injecting leaching solutions and gases (water, carbon dioxide, and oxygen) into underground ore formations through wells. This dissolves the uranium in the ore, which is then extracted to the surface by submersible pumps lowered into pumping wells for further processing. Therefore, submersible pumps in pumping wells are the most widely used downhole equipment. These pumps are lowered via riser pipes and cables, and once powered on, they begin operating to extract the leaching solution to the surface for further processing.

[0003] Given the operating characteristics of submersible pumps, they must be lowered to a distance below the well's liquid surface. This distance depends on the drop in the well's liquid level during operation, meaning a certain immersion depth must be maintained for the pump during operation. However, as underground mining has progressed deeper, the lowering depth of submersible pumps has increased from tens of meters in the initial stage to approximately 400 meters at its deepest point, due to varying water level parameters. Consequently, the workload of raising and lowering submersible pumps has also increased significantly.

[0004] Currently, the most widely used operating equipment is the manual winch, which is usually modified from a truck or heavy truck. The winch is installed above the cargo carrier and rotates via electric or hydraulic drive to lift or lower the liquid lift pipe. However, when lifting the pump, the lift pipe and cable are long. The lift pipe is wound on the winch, while the cable is placed on the ground or on the pump truck. The cable is quite heavy (1 kg / m, total weight 200 kg to 300 kg), requiring a dedicated person to organize it to prevent it from getting tangled or knotted. The overall workload is considerable. Another person is needed to untie the cable from the lift pipe, and the winch needs to be frequently started and stopped when lifting the pump. After the cable and riser pipe are connected to the submersible pump, the pump is lowered. Lowering is time-consuming, and the main load is borne by the riser pipe. To ensure the normal use of hundreds of meters of cable, the load is evenly distributed in sections. The riser pipe and cable need to be fixed every 3m to 10m. Currently, double fixing with nylon rope and electrical tape is generally used, and each binding takes about 20 to 30 seconds. If the cable is not properly bound, if it is too loose, multiple sections will overlap and become congested in the well shaft. When the pump is lifted, the cable is easily damaged and broken, causing unnecessary losses (about 30,000 yuan for 300m of cable). If it is too tight, it will increase the lowering construction time and be difficult to untie when lifting the pump. Lowering and lifting the submersible pump is time-consuming and labor-intensive, with high manpower consumption, which affects work efficiency. Summary of the Invention

[0059] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0060] like Figure 1 As shown, according to a first aspect of the embodiments of this application, a uranium leaching mining cable lifting and bundling device is proposed, comprising: a coiling device 11 and a bundling device 12; the coiling device 11 includes two winch mechanisms, a first winch mechanism 111 for coiling the lifting pipe 23, and a second winch mechanism 112 for coiling the cable 24; the bundling device 12 is disposed between the first winch mechanism 111 and the second winch mechanism 112, the lifting pipe 23 and the cable 24 pass through the same end of the bundling device 12, and the bundling device 12 connects the lifting pipe 23 and the cable 24 into a whole to form a cable assembly.

[0061] The in-situ leaching uranium mining cable lifting and bundling device provided in this embodiment includes a first winch mechanism 111, a second winch mechanism 112, and a bundling device 12. The lifting pipe 23 is wound around the first winch mechanism 111, and the cable 24 is wound around the second winch mechanism 112. The dual winch mechanism for the lifting pipe 23 and cable 24 allows for rapid winding and unwinding of the lifting pipe 23 and cable 24, preventing the cable 24 from tangling or knotting. For in-situ leaching mines with rugged locations, it eliminates the need to coil the cable 24 on the ground, avoiding soil contamination, reducing the working area, and preventing repeated lifting and lowering of the cable 24 from contaminating the leachate in the well. When it is necessary to lower the lifting pipe 23 and cable 24... The riser pipe 23 is led out from the first winch mechanism 111, and the cable 24 is led out from the second winch mechanism 112. The riser pipe 23 and the cable 24 are then passed through the same end of the bundling device 12. During the process of releasing the riser pipe 23 and the cable 24 from the first winch mechanism 111 and the second winch mechanism 112, the bundling device 12 is used to bundle the continuously released riser pipe 23 and the cable 24 together. This improves the automation level of well site operations, saves labor costs, significantly reduces labor intensity, improves the efficiency of submersible pump lowering, and at the same time significantly reduces the contact time between operators and the cable assembly, reduces the risk of radioactive element contamination, and improves the safety of submersible pump lowering operations.

[0062] Furthermore, when the bundling device 12 bundles the lifting pipe 23 and the cable 24, the first winch mechanism 111 and the second winch mechanism 112 stop rotating to prevent the cable 24 from being damaged by friction with the bundling tape during the bundling process.

[0063] Furthermore, when it is necessary to lift the submersible pump, the first winch mechanism 111 and the second winch mechanism 112 are reversed to lift the cable assembly of the pipe 23, and the binding tape of the cable assembly near the winch mechanism is continuously cut to separate the lifting pipe 23 from the cable 24 and respectively wind it onto the first winch mechanism 111 and the second winch mechanism 112.

[0064] In some examples, the first winch mechanism 111 is made of steel with a strength superior to No. 45 steel. The first winch mechanism 111 includes a first winch body and a first winch shaft. The minimum inner diameter of the root of the first winch body is 1m, and the outer diameter of the first winch body is >2.8m. The outer diameter of the first winch body is determined according to the coil volume of the lifting pipe 23. The first winch shaft is made of round steel with a diameter of 60mm or more, and the first winch shaft is rigidly connected to the first winch body.

[0065] In some examples, the second winch mechanism 112 is made of steel of better quality than 45# steel. The second winch mechanism 112 includes a second winch body and a second winch shaft. The minimum inner diameter of the root of the second winch body is 0.5m, and the outer diameter of the second winch body is >1.8m. The outer diameter of the second winch body is determined according to the volume of the cable 24 coils. The second winch shaft is made of round steel with a diameter of 40mm or more, and the second winch shaft is rigidly connected to the second winch body.

[0066] Specifically, the strapping device 12 is the Zhiyue series KH-1216 automatic open-loop strapping machine sold by Suzhou Ganlu Electromechanical Technology Co., Ltd., which uses a hot-melt strapping method for strapping, and the strapping efficiency is adjustable. As the preferred option, the strapping efficiency is 1.2s / cycle.

[0067] like Figure 1 As shown, in one feasible embodiment, the in-situ leaching uranium mining cable lifting and bundling device further includes: a limiting arm 13; the limiting arm 13 is arranged on the bundling platform of the bundling device 12, the first end of the limiting arm 13 is rotatably connected to the bundling platform, and the limiting arm 13 rotates in the horizontal plane; there is a gap between the second end of the limiting arm 13 and the bundling platform, and the gap allows the cable assembly to pass through.

[0068] In this technical solution, the limiting arm 13 is an open-loop design. A rotatable limiting arm 13 is installed on the binding platform of the binding device 12. When the limiting arm 13 rotates to the position where the gap between its second end and the binding platform is minimal, the limiting arm 13 is in the coiling position. By allowing the lifting tube 23 and cable 24 to pass through the limiting arm 13, the limiting arm 13 can coil and limit the lifting tube 23 and cable 24, preventing excessive spacing between them and improving the binding effect of the strapping. When the limiting arm 13... When the second end of 3 rotates to the limit position far away from the bundling platform, the gap between the second end of the limiting arm 13 and the bundling platform reaches its maximum. The limiting arm 13 is in the cable installation position, which makes it easy to put the lifting pipe 23 and the cable 24 into the limiting arm 13 from the gap position between the second end of the limiting arm 13 and the bundling platform. This allows the lifting pipe 23 and the cable 24 to be bundled at any position, or the cable assembly to be removed from the limiting arm 13 at any position after bundling, thus improving the flexibility of the bundling operation of the lifting pipe 23 and the cable 24.

[0069] Furthermore, when lifting the cable assembly without needing to tie it, the limiting arm 13 is rotated horizontally to prevent the limiting arm 13 from being pulled and damaged.

[0070] In some examples, the pre-tightening force of the strapping device 12 is ≥80N, the strapping tape is made of PET plastic steel or OPP material, the width is >2cm, the thickness is >0.1mm, the single-cut hot melt strapping time is <5s, and the hot melt performance is good; when the soaking medium is mineral water, the performance is stable, the equivalent diameter of the strapping ring is >15cm (the maximum diameter of the cable is about 8cm), and there is a certain amount of swing space during lifting and lowering to prevent the limit arm 13 from being pulled and damaged.

[0071] like Figure 1 As shown, in one feasible embodiment, the in-situ leaching uranium mining cable lifting and bundling device further includes: a limiting mechanism 14; the limiting mechanism 14 is disposed between the first winch mechanism 111 and the second winch mechanism 112, the lifting pipe 23 and the cable 24 pass through the same end of the bundling device 12, the limiting mechanism 14 makes rolling contact with the lifting pipe 23, so that the limiting mechanism 14 makes rolling contact with the cable 24, and the limiting mechanism 14 constrains the lifting pipe 23 and the cable 24.

[0072] In this technical solution, the lifting tube 23 and the cable 24 pass through the limiting mechanism 14, so that the limiting mechanism 14 can gather and limit the lifting tube 23 and the cable 24, and make the limiting mechanism 14 roll contact with the lifting tube 23 and the cable 24. This ensures that the binding device 12 will not fail or be damaged by pulling due to excessive spacing between the lifting tube 23 and the cable 24. While ensuring the limiting and restraining effect of the limiting mechanism 14 on the lifting tube 23 and the cable 24, the friction between the cable 24 and the limiting mechanism 14 is reduced, avoiding damage to the cable 24 under the squeezing of the limiting mechanism 14 and the lifting tube 23, and preventing damage to the cable 24 during the binding process.

[0073] like Figure 2 As shown, in one feasible embodiment, the limiting mechanism 14 includes: a support frame 141, a limiting outer ring 142, a hinge arm 143, an inner ring bracket 144, and a ball bearing 145; the first end of the hinge arm 143 is movably connected to the support frame 141, the second end of the hinge arm 143 passes through the limiting outer ring 142, and the hinge arm 143 is slidably connected to the limiting outer ring 142; the inner ring bracket 144 is disposed inside the limiting outer ring 142, and the inner ring bracket 144 is connected to the second end of the hinge arm 143; the ball bearing 145 is embedded in the side wall of the inner ring bracket 144 away from the limiting outer ring 142, and the ball bearing 145 rolls in contact with the inner ring bracket 144; wherein, there are three hinge arms 143, the included angle between two adjacent hinge arms 143 is 120 degrees, the inner ring bracket 144 corresponds one-to-one with the hinge arms 143, and there is a gap between two inner ring brackets 144.

[0074] In this technical solution, the limiting mechanism 14 has a double-layer structure. The outer layer is a fixed ring, and the inner layer consists of three inner ring brackets 144 controlled by three hinge arms 143 respectively. The hinge arms 143 pass through the limiting outer ring 142, and the hinge arms 143 are slidably connected to the limiting outer ring 142 so as to support the three hinge arms 143 through the limiting outer ring 142. The inner ring brackets 144 are supported by the corresponding hinge arms 143. The inner wall of the inner ring brackets 144 is embedded with ball bearings 145. The ball bearings 145 provide rolling support and constraint for the lifting pipe 23 and the cable 24, ensuring the flexibility of the lifting pipe 23 and the cable 24 in retraction and extension, and preventing the lifting pipe 23 and the cable 24 from pulling and damaging the binding device 12.

[0075] Furthermore, the included angle between two adjacent hinge arms 143 is 120°, and three corresponding inner ring brackets 144 are provided so that the constraint force of the inner ring brackets 144 on the lifting pipe 23 and the cable 24 can be distributed more evenly, preventing the cable 24 from being damaged due to concentrated pressure.

[0076] like Figure 2 As shown, in one feasible embodiment, the articulated arm 143 includes an elastic adjustment section 15 located outside the limiting outer ring 142, and the elastic adjustment section 15 is used to adjust the distance between the inner ring bracket 144 and the limiting outer ring 142.

[0077] In this technical solution, the length of the hinge arm 143 can be adjusted by extending and retracting the elastic adjustment section 15, thereby adjusting the distance between the inner ring bracket 144 and the limiting outer ring 142, thus adjusting the inner diameter of the constraint structure, so as to adjust the constraint pre-tightening force of the limiting mechanism 14 on the lifting pipe 23 and the cable 24. Before bundling, the lifting pipe 23 and the cable 24 are pre-tightened to ensure that the tightness of the cable assembly bundling is appropriate, avoiding excessively loose bundling that causes multiple sections of the cable 24 to overlap and become congested in the wellbore, thereby preventing the cable 24 from being pulled off and damaged when the pump is lifted. At the same time, it avoids bundling that is too tight or too dense, ensuring that the bundling tape can be easily untied during the pump lifting process.

[0078] In some examples, the central angle of each inner ring bracket 144 is ≤110°, and space is reserved for the inner ring brackets 144 to approach each other during bundling, so that the three inner ring brackets 144 can close and tighten, thereby increasing the constraint force on the lifting pipe 23 and the cable 24; the limiting outer ring 142 has the same thickness as the inner ring brackets 144 and is ≤25mm, and the diameter of the ball 145 is ≥6mm. Let the diameter of the circle formed by the three inner ring brackets 144 be d, 25mm≤dmax-dmin≤5mm; the inner diameter of the limiting outer ring 142 is 120% to 150% of the maximum width of the cable assembly.

[0079] In some examples, the elastic adjustment section 15 uses a threaded adjustment energy storage spring produced by Zhejiang Jinbawang Spring Co., Ltd. The threaded adjustment energy storage spring uses a combination of threaded rod and threaded block. By rotating the threaded rod, the contraction and extension of the connecting spring are realized, thereby adjusting the elastic force. The threaded adjustment energy storage spring is used in conjunction with an electromagnetic device, and the extension and retraction of the threaded rod are controlled by a solenoid valve to realize the electronic control adjustment of the elastic force.

[0080] Specifically, the normal force of the elastic adjustment section 15 is ≥100N.

[0081] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the in-situ leaching uranium mining cable lifting and bundling device further includes: a cutter 16, which is disposed on the limiting mechanism 14 and is used to cut the bundling tape; the cutter 16 includes a handle 161 and a cutter head 162; the first end of the handle 161 is adjustablely disposed on the limiting mechanism 14; the cutter head 162 is fixedly connected to the second end of the handle 161.

[0082] In this technical solution, when the pump is lifted, the first winch mechanism 111 and the second winch mechanism 112 reverse their directions. The lifting pipe 23 and the cable 24 are wound onto the first stirring mechanism and the second winch mechanism 112 respectively under the support of the inner ring bracket 144 and the ball bearing 145. During winding, a certain space is formed between the lifting pipe 23 and the cable 24. The cutter 16 rotates downward, that is, the handle 161 drives the cutter head 162 to rotate downward, so that the cutter head 162 moves with the cable assembly to automatically cut the binding tape, so that the automatic lifting of the submersible pump can be carried out smoothly, further reducing the intensity of manual labor and improving the efficiency of pump lifting.

[0083] In this technical solution, when the cable assembly is lifted, the lifting pipe 23 and the cable 24 pass through the limiting mechanism 14 and are wound up by two winches respectively. The lifting pipe 23 and the cable 24 separate to form a gap. The adjusting cutter 16 rotates downward and falls down, cutting the binding tape as the cable assembly moves. When the cable assembly is lowered, the adjusting cutter 16 rotates upward and lifts up. The cable assembly passes normally through the constraint of the limiting mechanism 14 and is automatically bound by the binding device 12.

[0084] In some examples, the blade 162 includes a blade made of stainless steel hook blade that can easily cut PET or OPP strapping. The blade is removable and replaceable to ensure the durability of the strapping cutting structure. The handle 161 is welded or riveted to the blade 162. The handle 161 is made of stainless steel and has a length ≥20cm and a diameter ≥1cm.

[0085] like Figure 1As shown, in one feasible embodiment, the in-situ leaching uranium mining cable lifting and bundling device further includes: a first drive assembly 18, a first torque sensor 19, a second drive assembly 20, and a second torque sensor 21; the first drive assembly 18 includes a first drive shaft, which is connected to the first winch shaft of the first winch mechanism 111, so as to drive the first winch mechanism 111 to rotate through the first drive assembly 18; the first torque sensor 19 is disposed on the first winch mechanism 111, and the first torque sensor 19 monitors the torsional torque of the first winch shaft; the second drive assembly 20 includes a second drive shaft, which is connected to the second winch shaft of the second winch mechanism 112, so as to drive the second winch mechanism 112 to rotate through the second drive assembly 20; the second torque sensor 21 is disposed on the second winch mechanism 112, and the second torque sensor 21 monitors the torsional torque of the second winch shaft.

[0086] In this technical solution, the first torque sensor 19 measures the torque of the winch shaft of the first winch mechanism 111, which is driven by the first drive assembly 18 to realize the automatic release or retraction of the lifting tube 23; the second torque sensor 21 measures the torque of the winch shaft of the second winch mechanism 112, which is driven by the second drive assembly 20 to realize the automatic release or retraction of the cable 24, so as to precisely control the release and retraction speed and timing of the lifting tube 23 and the cable 24. Based on the measurement values ​​of the first torque sensor 19 and the second torque sensor 21, the output torque of the first drive assembly 18 and the second drive assembly 20 is adjusted, so that the lifting tube 23 and the cable 24 can move synchronously, avoiding the cable 24 from being pulled or piling up in a certain place, and ensuring the flatness of the cable assembly after binding.

[0087] As a preferred option, both the first torque sensor 19 and the second torque sensor 21 are torque sensors with temperature compensation function to adapt to different working conditions in winter and summer in the leaching mine. The measurement error of the torque of the winch shaft is ≤0.2% and the linearity is <0.3%, ensuring that changes in torque load will not cause the error of lifting / lowering the lifting pipe 23 and the cable 24 to gradually increase.

[0088] like Figure 1 As shown, in one feasible embodiment, the in-situ leaching uranium mining cable lifting and bundling device further includes: a data acquisition control box 22, which acquires the torsional torque data of the first torque sensor 19 and the torsional torque data of the second torque sensor 21; the data acquisition control box 22 controls the rotational speed of the first drive component 18 and / or the second drive component 20 based on the torsional torque data of the first torque sensor 19 and the torsional torque data of the second torque sensor 21.

[0089] In this technical solution, the acquisition control box 22 acquires the torsional torque data measured by the first torque sensor 19 and the second torque sensor 21. The acquisition control box 22 adjusts the rotation speed of the corresponding drive component based on the data acquired by the two torque sensors, thereby improving the synchronization of the release and retraction of the lift tube 23 and the cable 24.

[0090] As a preferred option, the acquisition frequency of the acquisition control box 22 is ≥50Hz to ensure the timeliness of the acquisition control box 22 in adjusting the output torque of the first drive component 18 and the second drive component 20, improve the synchronization of the lifting tube 23 and the cable 24 in winding and unwinding, and avoid the cable 24 from accumulating or being pulled too hard.

[0091] like Figure 3 As shown, according to a second aspect of this application, a method for lifting, lowering, and bundling uranium mining cables is proposed, applicable to the uranium mining cable lifting, lowering, and bundling device as described in any of the above technical solutions. The method includes:

[0092] Step 100: Lead out the lifting pipe 23 and cable 24 on the coiling device 11, so that the lifting pipe 23 and cable 24 pass through the binding device 12. During the lowering process of the lifting pipe 23 and cable 24, they pass through the binding device 12. The binding device 12 automatically binds the passing lifting pipe 23 and cable 24 without affecting the normal lowering of the lifting pipe 23 and cable 24.

[0093] Step 200: Connect the lift pipe 23 to the submersible pump and the cable 24 to the motor. The lift pipe 23 bears the main load when the submersible pump is lifted and lowered, and the cable 24 supplies power to the motor of the submersible pump.

[0094] Step 300: Adjust the speed of the first winch mechanism 111 and the second winch mechanism 112 so that the release speed of the lifting tube 23 is consistent with that of the cable 24.

[0095] Step 400: The bundling device 12 bundles the lifting pipe 23 and the cable 24 together to form a cable assembly;

[0096] Step 500: After the liquid pumping operation is completed, control the first winch mechanism 111 and the second winch mechanism 112 to reverse. The first winch mechanism 111 winds up the lifting pipe 23, and the second winch mechanism 112 winds up the cable 24 to lift the submersible pump.

[0097] Step 600: Cut the strapping tape on the cable assembly to separate the lifting tube 23 from the cable 24, ensuring that the lifting tube 23 and the cable 24 are wound separately.

[0098] The method for lifting, lowering, and bundling uranium mining cables provided in this application embodiment involves the following: the lifting pipe 23 is raised and lowered via the rotation of the first winch mechanism 111, and the cable 24 is raised and lowered via the rotation of the second winch mechanism 112. The dual winch mechanism for the lifting pipe 23 and cable 24 allows for rapid raising / lowering of both, preventing the cable 24 from becoming tangled or knotted. In cases of rugged terrain in uranium mining, the cable 24 does not need to be coiled on the ground, avoiding soil contamination, reducing the working area, and preventing repeated lifting and lowering of the cable 24 from contaminating the leaching fluid. The lifting pipe 23 is led out from the first winch mechanism 111, and the cable 24 is led out from the second winch mechanism 112, with both pipes passing through the same end of the bundling device 12. Before the riser pipe 23 and cable 24 are connected, the speed of the first winch mechanism 111 and the second winch mechanism 112 are adjusted to ensure the synchronicity of the movement of the riser pipe 23 and cable 24. Then, the riser pipe 23 and cable 24 are bundled into a cable assembly by the bundling device 12 to prevent the cable 24 from being partially piled up or pulled due to asynchronous movement between the cable 24 and the riser pipe 23. This prevents the cable 24 from being damaged during the automatic bundling process. The bundling device 12 bundles the continuously released riser pipe 23 and cable 24 into a whole, improving the automation level of well site operations, saving labor costs, significantly reducing labor intensity, improving the efficiency of submersible pump lowering, and at the same time significantly reducing the contact time between operators and the cable assembly, reducing the risk of radioactive element contamination and improving the safety of submersible pump lowering operations.

[0099] In one feasible implementation, the bundling device 12 bundles the lifting pipe 23 and the cable 24 together to form a cable assembly, including the following steps:

[0100] The acquisition control box 22 controls the first winch mechanism 111 and the second winch mechanism 112 to stop rotating;

[0101] The acquisition control box 22 controls the extension of the elastic adjustment section 15, reduces the inner ring diameter of the limiting mechanism 14, and constrains the lifting tube 23 and the cable 24;

[0102] The acquisition control box 22 controls the bundling device 12 to bundle the lifting pipe 23 and the cable 24.

[0103] In this technical solution, each time the cable is bundled, the acquisition control box 22 controls the two winch mechanisms to stop rotating. At the same time, the acquisition control box 22 sends an operation signal to control the three elastic adjustment sections 15 to extend synchronously, so as to reduce the inner diameter of the inner ring and constrain the lifting pipe 23 and the cable 24. Then, the acquisition control box 22 sends a bundling signal to the bundling device, and the bundling device 12 automatically bundles the lifting pipe 23 and the cable 24. The bundling device 12 heat-melts both ends of the bundling tape and cuts the bundling tape, so that the bundling tape is separated from the bundling device 12.

[0104] Furthermore, after one bundle is completed, the acquisition control box 22 sends a signal to control the three elastic adjustment sections 15 to close, so that the elastic adjustment sections 15 automatically retract, facilitating the smooth passage of the cable assembly through the limit mechanism 14. Then, the two winch mechanisms are started to continue lowering the lifting pipe 23 and cable 24 until the acquisition control box 22 controls the two winch mechanisms to stop again during the next bundle.

[0105] Furthermore, the number of times the binding device 12 binds when the winch mechanism stops rotating can be set according to actual needs, that is, the number of times it binds at the same position.

[0106] As a preferred option, when the submersible pump is lowered to a depth of more than 200m, securing the cable assembly twice at the same location can ensure that the cable assembly does not slip off.

[0107] Furthermore, the first winch mechanism 111 is driven by the first drive assembly 18, and the first torque sensor 19 monitors the torque of the first winch mechanism 111. The second winch mechanism 112 is driven by the second drive assembly 20, and the second torque sensor 21 monitors the torque of the second winch mechanism 112. The acquisition control box 22 adjusts the first drive assembly 18 and the second drive assembly 20 according to the collected monitoring data from the first torque sensor 19 and the second torque sensor 21, thereby adjusting the speed and start / stop of the first winch mechanism 111 and the second winch mechanism 112, so as to ensure the synchronicity of the movement of the lifting pipe 23 and the cable 24.

[0108] In some examples, when lowering the submersible pump, the binding device 12 and the limiting mechanism 14 work together to lift the handle 161 or remove the blade to ensure the safety of the lifting pipe 23 and cable 24. During the lowering process, the lifting pipe 23 and cable 24 are first led out from the two winch mechanisms, passing through the limiting mechanism 14, and then exiting through the limiting arm 13 of the binding device 12. The lifting pipe 23 is then connected to the submersible pump, and the cable 24 is connected to the motor. After completion, the pump is lowered into the well. The speed of the two winch mechanisms is adjusted, and then the lifting pipe 23 and cable 24 are bound according to the speed adjustment mechanism. Each time binding is performed, the two winch mechanisms need to stop rotating. At this time, the acquisition and control box 22 sends an operation signal to control the three elastic adjustment sections 15 of the limiting mechanism 14 to extend synchronously, thereby reducing the inner ring diameter of the limiting mechanism 14 and constraining the lifting pipe 23 and cable 24. Within 1 second after the limit mechanism 14 is adjusted, the acquisition and control box 22 sends a strapping signal to the strapping device 12. The strapping tape shrinks evenly along the inner ring of the strapping device 12 until the pretension of the strapping tape reaches the preset value. After the two ends of the strapping tape are heat-fused, it is automatically cut off, completing one strapping operation. As a preferred option, the preset value of the pretension of the strapping tape is 60N to 80N.

[0109] In some examples, when the submersible pump is lifted, the securing device 12 is not activated, and the limiting arm 13 can be rotated 90° to avoid contact with the cable assembly, preventing deformation and damage to the limiting arm 13. When the cable assembly is pulled out of the well and is within the positioning mechanism, the acquisition control box 22 de-energizes the elastic adjustment section 15, which remains in its natural state and does not retract. The limiting mechanism 14 is at its maximum inner diameter. After passing through the limiting mechanism 14, the cable assembly is secured by two strands... The winch mechanism retracts to create space by pulling the cable tie apart through the cable assembly. Then, the cutter handle 161 is controlled downwards, making it parallel to the axis of the limiting mechanism 14 to cut the cable tie. After cutting, the cutter 16 is raised, making the cutter handle 161 perpendicular to the axis of the limiting mechanism 14. By continuously raising and lowering the cutter handle 161, the cutter head 162 is prevented from remaining between the cable assemblies, thus preventing accidental cutting of the lifting pipe 23 and cable 24, until the lifting pipe 23 and cable 24 are rewound. If the cutter head 162 accidentally cuts the cable 24 and lifting pipe 23, the winch mechanism can be shut down immediately, the fault rectified, and operation resumed.

[0110] Specifically, the handle 161 is driven by an electric push rod, which is electrically connected to the acquisition control box 22. The angle of the handle 161 is adjusted by the acquisition control box 22. The handle 161 can also be driven manually to further prevent the cutter head 162 from accidentally cutting the cable 24 and the lifting tube 23.

[0111] In one feasible implementation, the control method for the winch mechanism includes:

[0112] Monitor the torque F1 of the first winch mechanism and the torque F2 of the second winch mechanism;

[0113] When 0 N·m < F1 < 1000 N·m, calculate the load difference rate (L) between the first winch mechanism and the second winch mechanism;

[0114] If L<0%, control the first winch mechanism to wind up at a speed of 2m / s for 2s, and control the binding device to bind once every 2s to 3s;

[0115] If 0% ≤ L ≤ 95%, control the first winch mechanism at 0.5 m / s 2 The acceleration speeds up the roll, and the binding device is controlled to bind once every 8 to 10 seconds;

[0116] If L>95%, control the first winch mechanism at 0.2m / s 2 The acceleration decelerates until L≤95%, at which point the control strapping device stops strapping.

[0117] In this technical solution, the torque F1 of the first winch mechanism and the torque F2 of the second winch mechanism are monitored. When 0 N·m < F1 < 1000 N·m, it indicates that the load on the first winch mechanism is low. This may be because the second winch mechanism is too tight and bears most of the load, or because the lifting pipe has just been connected to the submersible pump and the two winch mechanisms have not yet started to rotate. Therefore, it is necessary to make a judgment based on the load difference rate (L) of the two winch mechanisms. When L < 0%, it indicates that the second winch mechanism bears a larger load than the first winch mechanism. However, since it is still within a safe range, adjustment is needed to balance the load of the two winch mechanisms. At this time, the data acquisition and control box sends a signal to control the first winch mechanism to reverse at a speed of 2 m / s within 0.5 s, continuing for 2 s, until the L value increases. Then, the data acquisition and control box sends a signal to control the binding device to perform a binding action every 2 to 3 s. During binding, the data acquisition and control box controls both winch mechanisms to stop working. At this time, the binding density is relatively high, which can ensure the binding is stable and reduce the load on the second winch mechanism, thereby increasing the L value. When 0 ≤ L ≤ 95%, it indicates that the first winch mechanism bears a larger load than the second winch mechanism, but the overall load is not large. At this time, the data acquisition and control box controls the first winch mechanism to reverse at a speed of 0.5 m / s within 1 s. 2 The acceleration is slowly increased for 2 seconds until the L value increases. Then, the acquisition and control box sends a signal to control the bundling device to perform bundling. During bundling, the acquisition and control box controls the bundling frequency to decrease, performing one bundling every 8 to 10 seconds, with a bundling spacing of approximately 5 meters. When L > 95%, it indicates that the first winch mechanism bears most of the load, but to ensure that the cable on the second winch mechanism does not become loose or tangled, the first winch mechanism needs to decelerate, reducing the L value. The acquisition and control box controls the first winch mechanism to rotate at 0.2 m / s. 2 The acceleration decelerates until the L value drops below 95%; then, the first winch mechanism is controlled by the acquisition and control box to move at 0.5 m / s². 2 The acceleration is slow and the rotation is slowed for 2 seconds. During this stage, the load is small, and no bundling operation is performed. In the stage where 0 N·m < F1 < 1000 N·m, the maximum speed of both the first and second winch mechanisms is ≤0.8 m / s, and the L value is controlled at around 95%. This ensures both the overall winding and unwinding speed and allows the cable to be wound and unwound normally, preventing the cable from being damaged due to excessive tightness or becoming loose and tangled.

[0118] In one feasible implementation, the control method for the winch mechanism further includes:

[0119] Monitor the torque F1 of the first winch mechanism and the torque F2 of the second winch mechanism;

[0120] When F1 ≥ 1000 N·m, calculate the load change rate (Ca):

[0121] Ca = Average amplitude of load increase / Average amplitude of load decrease

[0122] If Ca ≥ 5, tighten the second winch mechanism to make 300 N·m < F2 ≤ 500 N·m, and control the strapping device to strap once every 5 s;

[0123] If 1 ≤ Ca < 5, control the second winch mechanism to accelerate the lowering to make 200 N·m < F2 ≤ 300 N·m, and control the strapping device to strap once every 8 s;

[0124] If Ca < 1, control the first winch mechanism to accelerate the winding up at an acceleration of 0.5 m / s 2 to maintain 100 N·m ≤ F2 ≤ 200 N·m, and control the strapping device to strap once every 10 s.

[0125] In this technical solution, when F1 ≥ 1000 N·m, it indicates that the lifting pipe and the cable are in a normal winding and unwinding state, and the load of the lifting pipe is normal. However, it is still necessary to calculate the load fluctuation coefficient (Ca) and adjust the speed to ensure the safe winding and unwinding of the lifting pipe and the cable. If Ca ≥ 5, it means that within this 1 s, the load of the first winch mechanism increases sharply. The second winch mechanism needs to be tightened appropriately to share the load of the first winch mechanism, and maintain the torque of the second winch mechanism at 300 N·m < F2 ≤ 500 N·m to control the tightness of the cable. If F2 ≥ 5000 N·m, the control box collects and urgently shuts down the second winch mechanism, and controls the strapping device to perform an automatic strapping operation once every 5 s. If 5 ≥ Ca ≥ 1, it means that within this 1 s, the load of the first winch mechanism increases slowly but is still in a normal state. Accelerate the lowering of the second winch mechanism to relax the cable and reduce the load of the second winch mechanism. During this period, maintain the torque of the second winch mechanism at 200 N·m < F2 ≤ 300 N·m, and at the same time keep the increment of F2 less than 500 N·m. If the increment of F2 exceeds 500 N·m, control the second winch mechanism to reduce and decrease the load of the second winch mechanism. At the same time, the strapping device performs an automatic strapping operation once every 8 s. If Ca < 1, it means that within this 1 s, the load of the lifting pipe decreases and is in the upward lifting state. At this time, control the first winch mechanism to accelerate the winding up at an acceleration of 0.5 m / s 2 until Ca ≥ 1; during this process, maintain the torque of the second winch mechanism at 100 N·m ≤ F2 ≤ 200 N·m to prevent the cable on the second winch mechanism from loosening, and the strapping device performs an automatic strapping operation once every 10 s.

[0126] In some examples, the load fluctuation coefficient (Ca) is calculated as follows: the sampling frequency of the torque sensor is f = NHz, meaning N parameters are collected per second, and the calculation period is 1 second. That is, within one calculation period, there are N+1 sampling points. The difference between the next sampling point and the previous sampling point is a calculation result. A positive result indicates an increase, and a negative result indicates a decrease. The N calculation results are divided into an increase group and a decrease group according to their signs. The average of the absolute values ​​of the two groups is then calculated to determine the Ca value.
