[0001] The present application belongs to the technical field of equipment processing, in particular to a positioning device for float collar processing. BACKGROUND

[0002] In oil drilling operations, cementing work is very important, any mistake can make a good quality drilling into a well that is used even scrapped, so the float collar of cementing tool is very important, the main function of float collar is to guide the casing into the well smoothly, adjust the buoyancy of casing string when lowering the casing, prevent the cement from flowing back into the casing during cementing, the quality of float collar directly affects the quality of cementing.

[0003] Because the working environment of float collar device is relatively harsh, and the demand quantity is larger, batch production is needed, and the float collar device needs to completely block the inside of the casing, so the sealing performance is required to be good, and the filling block at the shaft center also needs to be positioned and processed, so as to ensure that the shaft center line is the same as the shaft center line of the pipeline, but the float collar device is easily affected by gravity during processing, so that the filling block with a certain weight is deviated from the pipe wall under the interference of gravity, thereby pressing the pipe wall, and the pipe wall will be slightly deformed after being pressed, thereby causing the deviation of the shaft center lines of the two, so the positioning and calibration device needs to be improved. SUMMARY

[0004] In view of the defects of the prior art, the technical scheme adopted by the present application to solve the technical problems is: a positioning device for float collar processing, including a control pad, a torque motor is connected to the shaft center of the top of the control pad, the top of the output shaft of the torque motor is inserted into the sliding plug through the slot, the surface of the sliding plug is rotatably connected to the processing device, the surface of the processing device is slidably connected to the protective shell, including a cutting component, which can cooperate with the processing device to cut the surface of the sliding plug, the surface of the cutting component is fixedly connected to the traction device, and the bottom of the traction device is fixedly connected to the top of the surface of the control pad; the protective shell includes a cutting groove shell, a limiting suction rod is fixedly connected to the middle of the inner cavity of the cutting groove shell, and inner rotary jibs are fixedly connected to the two sides of the inner cavity of the cutting groove shell, a friction rotating rod is rotatably connected to the shaft center of the inner rotary jib, and the surface of the friction rotating rod is rollingly connected to the surface of the traction device; before using the device, the sliding plug to be processed needs to be installed on the device, at this time, the torque motor is adjusted downward through the control pad, then the sliding plug is moved to the middle of the control pad along the guide sliding rail, at this time, the plug rod at the top of the torque motor is inserted into the slot at the bottom of the sliding plug, then the torque motor is raised upward by the control pad, so that the sliding plug is inserted into the inside of the processing device, then the matching sliding cylinder matched with the surface of the sliding plug is inserted into the top of the processing device, and the preparation work is completed.

[0005] Preferably, the processing device comprises an inner roller, the top end of the inner roller is fixedly connected with a top end sleeve, the top of the surface of the top end sleeve is fixedly connected with a bunching swivel, the top of the surface of the bunching swivel is rotatably connected with a side clamping plate, and the inner cavity of the inner roller is uniformly provided with a pressure receiving part on both sides. The top surface of the control cushion plate is fixedly connected with guide rails on both sides, the inner cavity of the control cushion plate is fixedly connected with a wire pulling vertical rod at both ends, the bottom end of the pressure receiving part is fixedly connected with the inner cavity of the control cushion plate through a vertical guide wire, and the top surface of the control cushion plate is uniformly provided with a one-way air vent. When the sliding plug is cut, the torque motor controls the sliding plug to continuously rotate, and the friction rotating rods on both sides rotate under the control of the inner rotating frame. Through the friction force on the outer surface, the surface of the external guide shell slides along the side slot of the inner roller and the slot shell. Since the inner rotating frames on both sides are synchronized, the moving distance of the external guide shells on both sides is the same. At this time, the side of the external guide shell far away from the wire pulling vertical rod is inserted into the side slot of the inner roller, the composite plug-in cylinder grinds the side surface of the sliding plug through the side cutting part, thereby reducing the diameter of the sliding plug blank, and gradually becoming a regular circle. After processing is completed, the torque motor pushes the sliding plug upwards, at which time the sliding plug can be directly inserted into the inner cavity of the matching sliding cylinder. Then, if the sliding plug can fit the inner cavity of the matching sliding cylinder, the sliding plug processing is completed, and the sliding plug and the matching sliding cylinder can be taken out at the same time. The device can cut and polish the sliding plug to make the sliding plug fit the inner cavity of the matching sliding cylinder, so as to accurately plug the port of the matching sliding cylinder. Moreover, when the sliding plug is processed, the sliding plug is located at the axial position of the device and rotates at all times, so the problem of deviation of the axial line of the matching sliding cylinder from the axial line of the sliding plug due to the influence of gravity does not occur.

[0006] Preferably, the number of limiting suction rods is two, one end of the limiting suction rod away from the slot shell is inserted into one side of the surface of the inner roller, the top of the inner cavity of the inner roller is inserted with a matching sliding cylinder, the surface of the side clamping plate is pressed against the surface of the matching sliding cylinder, and the surface of the sliding plug is the same in diameter as the inner cavity of the matching sliding cylinder. The device cuts and polishes the surface of the sliding plug through the cutters on both sides and the top. When the cutter cuts metal, the kinetic energy of the flying metal chips is large, which can easily cause injury and safety hazards. The device blocks the slot shell and the inner roller, the side slots of the slot shell and the inner roller are plugged by the cutters during cutting, thereby avoiding the problem of chip injury, and the slot shell and the inner roller can gather the chips on the upper surface of the control cushion plate for centralized cleaning, thereby optimizing the working environment.

[0007] Preferably, the traction device comprises an external guide shell, a composite insertion sleeve is slidably connected to the inner cavity of the external guide shell near one side of the sliding plug, a control traction rod is inserted into the top inner cavity of the composite insertion sleeve, a plug-in rod is fixedly connected to the bottom end of the control traction rod, a constant value pull rope is fixedly connected to the middle surface of the control traction rod, an external motor is inserted into the top inner cavity of the constant value pull rope, a buffer stop rod is fixedly connected to the inner cavity of the external guide shell away from the composite insertion sleeve, and a guide push plate is rotatably connected to the surface of the composite insertion sleeve. During cutting processing, the distance of the side blade inserted into the inner cavity of the inner roller needs to be adjusted, otherwise the side blade is easy to polish the sliding plug too much, at this time the control traction rod is not connected with the threaded drum through the plug-in rod, but under the rotating action of the external motor, the control traction rod starts to rotate, and then the constant value pull rope is wound on the outer surface, at this time under the traction of the constant value pull rope, the bottom end of the control traction rod pulls the composite insertion sleeve as a whole along the inner cavity of the external guide shell to the side close to the buffer stop rod, so as to pull the side blade through the composite insertion sleeve, thereby realizing the fine adjustment of the side blade.

[0008] Preferably, the constant value pull rope is fixedly connected to the inner cavity of the line vertical rod away from the control traction rod, a threaded drum is arranged at the top inner cavity of the composite insertion sleeve, a butt pie plate is slidably connected to the top inner cavity of the threaded drum, an inner rotor is fixedly connected to the shaft of the inner cavity of the butt pie plate through a fixed groove, and a one-way rotating fan is fixedly connected to the top end of the output shaft of the inner rotor. When the control traction rod is inserted into the inner cavity of the threaded drum through the plug-in rod at the bottom, the control traction rod can directly twist the threaded drum through the plug-in rod, so that the threaded drum spirally descends along the inner cavity of the composite insertion sleeve, thereby pushing the cutting part to descend, and the blade on the upper part of the cutting part grinds the top surface of the sliding plug. Moreover, after the plug-in rod is inserted into the inner cavity of the threaded drum and butts against the butt pie plate, the inner rotor also works under electricity, and the one-way rotating fan blows downward, at this time the butt pie plate descends to compress the spring sleeve below, thereby opening the bottom opening of the composite insertion sleeve, and the external guide shell has only one side groove guide opening, and the side groove guide opening is opposite to the sliding plug, so that the wind force is introduced to the sliding plug.

[0009] Preferably, the surface of the threaded drum is threadedly connected with the inner cavity of the composite plug-in sleeve through the threaded groove, the bottom end of the plug-in rod is slidably connected with the top of the inner cavity of the composite plug-in sleeve through the penetrating insertion port, the bottom end of the plug-in rod is extruded with the top of the counter-plate through the conductive sheet, and the bottom end of the counter-plate is slidably connected with the bottom of the inner cavity of the composite plug-in sleeve through the spring sleeve. The lateral cutting shell on both sides of the device is controlled to move by the control traction rod. Since the length of the constant value pull rope is fixed, the position of the lateral cutting shell can be intuitively fed back through the length of the constant value pull rope. After the composite plug-in sleeve is connected with the control traction rod, it can automatically blow air to the sliding plug during the machining process along the side cutting groove of the composite plug-in sleeve, so as to cool and clean the cutting surface of the lateral cutting shell and the surface of the sliding plug, thereby avoiding the problem of metal deformation caused by cutting internal energy.

[0010] Preferably, the cutting component comprises a connecting plate, a bent connecting rod is fixedly connected to one side of the inner cavity of the connecting plate close to the sliding plug, a top end blade is fixedly connected to the top end of the bent connecting rod, an adapter sleeve is fixedly connected to the bottom end of the bent connecting rod, a lateral cutting shell is fixedly connected to the surface of the bent connecting rod, fixed protrusions are uniformly arranged on one side of the inner cavity of the lateral cutting shell close to the sliding plug, a vertical pressing rod is slidably connected to the side of the inner cavity of the lateral cutting shell away from the fixed protrusions, a traction sliding rod is fixedly connected to the bottom end of the vertical pressing rod, and an impact rod is slidably connected to the inner cavity of the traction sliding rod. The bent connecting rod is pulled downward by the adapter sleeve, at which time the top end blade descends to contact the upper surface of the sliding plug with the sharp blade on the lower surface, thereby achieving polishing work. When the top end blade descends, the lower surface of the top end blade presses the top end of the vertical pressing rod, so that the vertical pressing rod slides downward along the inner cavity of the lateral cutting shell. At this time, the vertical pressing rod pushes the traction sliding rod below, and the lateral impact rod is extruded with the surface of the fixed protrusion when descending, and then separates from the fixed protrusion. Under the action of the elasticity in the inner cavity of the traction sliding rod, the inner cavity of the lateral cutting shell is impacted, so that the lateral cutting shell vibrates from inside to outside, thereby avoiding the problem that the cutting debris is adhered to the outer surface of the lateral cutting shell. One end of the impact rod is slidably connected with the inner cavity of the traction sliding rod through the spring groove, the other end of the impact rod is extruded with the surface of the fixed protrusion, one side of the lateral cutting shell close to the sliding plug is extruded with the side of the sliding plug, and the bottom end of the composite plug-in sleeve is rotationally connected with the inner cavity of the adapter sleeve.

[0011] Preferably, the top blade comprises a cutter clamp shell, a bridge spring is slidably connected to the top of the inner cavity of the cutter clamp shell, a cutting piece is slidably connected to the bottom of the inner cavity of the cutter clamp shell through a sliding groove, a stabilizing plate is slidably connected to the top of the surface of the cutting piece, built-in pry bars are rotatably connected to the two ends of the stabilizing plate, a butt joint pressing rod is rotatably connected to the end of the built-in pry bar away from the stabilizing plate, and the bottom end of the butt joint pressing rod is in mutual extrusion with the top end of the vertical pressing rod. The top blade of the device is arranged in an assembled manner, after the cutting piece is passivated, the passivated cutting piece can be taken out from the inner cavity of the cutter clamp shell, and then a new cutting piece is replaced, and the bottom end of the butt joint pressing rod is in mutual extrusion with the top end of the vertical pressing rod when the top blade works, at this time, the butt joint pressing rod slides along the inner cavity of the cutter clamp shell, so that the end of the built-in pry bar away from the stabilizing plate is rotated upward, at this time, the other end of the built-in pry bar presses the stabilizing plate downward, so that the cutting piece below is pressed tightly. The top blade of the device can polish the upper surface of the sliding plug, avoid that the side surface of the sliding plug gathers residues to the top of the sliding plug during cutting, the cutting piece of the top blade is convenient to replace, but the upper stabilizing plate needs to press downward on the top blade during work, so that the cutting piece does not relatively loosen with the cutting groove at the bottom end of the cutter clamp shell during work, and the problem of shaking is avoided.

[0012] Preferably, the pressure receiving component comprises an inner sliding block, a buffer roller is rotatably connected to the end of the inner sliding block close to the sliding plug, a thrust arm is slidably connected to the axis of the inner cavity of the buffer roller through a transfer rod, an inner built-in sleeve is slidably connected to the side of the inner sliding block away from the sliding plug, a hollow air cylinder is fixedly connected to the side of the inner built-in sleeve away from the inner sliding block, and a pressure pump is fixedly connected to the bottom of the inner cavity of the hollow air cylinder. After each processing of the sliding plug, the sliding plug cannot be directly inserted into the inner cavity of the matching sliding cylinder, otherwise the inner cavity of the matching sliding cylinder may be worn, at this time, the sliding plug can be first inserted into the upper part of the inner cavity of the inner roller, and then the torque motor is rotated, if the sliding plug rotates normally and the shape is normal, the buffer roller only rotates under the action of friction, otherwise the inner sliding block will be subjected to extrusion force, then slides along the inner cavity of the inner built-in sleeve, and then extrudes the hollow air cylinder, the inner cavity of the hollow air cylinder is extruded, the pressure increases, the pressure pump is subjected to the pressure, and the sliding plug continues to be processed through the feedback of the wires at the bottom end to the control pad.

[0013] The beneficial effects of the present application are as follows:

[0014] 1. The device can cut and polish the sliding plug, so that the sliding plug is matched with the inner cavity of the matching sliding cylinder, thereby accurately plugging the through hole of the matching sliding cylinder, and when the device processes the sliding plug, the sliding plug is at the axial position of the device and rotates at all times, so that the problem that the axial line of the matching sliding cylinder deviates from the axial line of the sliding plug due to the influence of gravity does not occur.

[0015] 2. The device cuts and polishes the surface of the sliding plug through the cutters on both sides and the top, and when the cutters cut metal, the kinetic energy of the metal debris is large, which can easily cause injury and safety hazards. The device blocks the side slot of the cut slot shell and the inner roller through the outer cut slot shell and the inner roller, and the cutters on both sides can block the side slot of the cut slot shell and the inner roller during cutting processing, thereby avoiding the problem of debris injury, and the cut slot shell and the inner roller can gather the debris on the upper surface of the control base plate for centralized cleaning, thereby optimizing the working environment.

[0016] 3. The lateral cutting shell on both sides of the device is controlled to move by the control traction rod. Since the length of the fixed value pull rope is fixed, the position of the lateral cutting shell can be intuitively fed back through the length of the fixed value pull rope. After the composite plug is connected with the control traction rod, it can automatically blow air to the sliding plug during processing along the side cutting slot of the composite plug, thereby cooling and cleaning the cutting surface of the lateral cutting shell and the surface of the sliding plug, avoiding the problem of metal deformation caused by cutting internal energy.

[0017] 4. The top blade of the device can polish the upper surface of the sliding plug, avoiding the accumulation of residues on the top of the sliding plug during cutting. The cutting blade of the top blade is convenient to replace, but the upper stabilizing plate is also needed to press the top blade downward during work, thereby avoiding the problem of relative looseness between the cutting blade and the cutting slot at the bottom of the cutter clamp shell during work, and further avoiding the problem of shaking.

[0018] 5. After each processing of the sliding plug, it cannot be directly inserted into the inner cavity of the matching sliding cylinder, otherwise it may cause wear of the inner cavity of the matching sliding cylinder. At this time, the sliding plug can be first inserted into the upper part of the inner cavity of the inner roller, and then rotated by the torque motor. If the sliding plug rotates normally and the shape is normal, the buffer roller only rotates under the action of friction force, otherwise the inner sliding block will be subjected to extrusion force, and then slide along the inner cavity of the built-in sleeve shell, thereby extruding the hollow air cylinder. After the inner cavity of the hollow air cylinder is extruded, the pressure increases, the pressure pump is subjected to the pressure, and the control base plate is fed back through the bottom lead, so that the sliding plug continues to process.

[0036] Before using the device, the sliding plug 13 to be processed needs to be installed on the device, at this time the torque motor 11 is adjusted downward through the control base plate 1, and then the sliding plug 13 is moved to the middle of the control base plate 1 along the guide slide rail 12, at this time the plug-in rod at the top end of the torque motor 11 is plug-in connected with the plug-in groove at the bottom of the sliding plug 13, then the torque motor 11 is raised upward by the control base plate 1, so that the sliding plug 13 is inserted into the inside of the processing device 3, and then the matching sliding cylinder 14 matched with the surface of the sliding plug 13 is inserted at the top end of the processing device 3, and the preparation work is completed.

[0037] When the sliding plug 13 is cut, the torque motor 11 controls the sliding plug 13 to continuously rotate, and the friction rotating rods 24 on the two sides rotate under the control of the inner rotating frame 23, and the surface of the outer guide shell 51 is slid along the side groove of the inner cylinder 31 and the slotting profile shell 21 through the friction force of the outer surface, so that the moving distances of the outer guide shells 51 on the two sides are the same, at this time the outer guide shell 51 away from the wire vertical rod 15 is inserted into the side groove of the inner cylinder 31, and then the composite plug-in barrel 6 is inserted into the inner cavity of the matching sliding cylinder 14 through the side cutting part 4 to grind the side surface of the sliding plug 13, so that the diameter of the sliding plug 13 is reduced, and gradually becomes a regular circle, after the processing is completed, the torque motor 11 pushes the sliding plug 13 upward, at this time the sliding plug 13 can be directly inserted into the inner cavity of the matching sliding cylinder 14, and then if the inner cavity of the matching sliding cylinder 14 can be matched with the sliding plug 13, the processing of the sliding plug 13 is completed, and the sliding plug 13 and the matching sliding cylinder 14 can be taken out at the same time.
