Technical Field
[0001] This utility model relates to the technical field of elastic centralizer processing equipment, specifically an integrated elastic centralizer processing equipment that facilitates flipping and loading / unloading. Background Technology
[0002] A centralizer is a tool used to correct the position of casing, commonly used in the oil and gas drilling industry. It provides support and guidance during casing running into the well to ensure that the casing is centered in the wellbore and to reduce casing swaying and tilting.
[0003] There are different models of centralizers depending on the different usage environments. One type is the integral elastic centralizer, which is made of seamless steel pipe, which is cut by plasma laser, then pressed into shape, and finally heat-treated, tempered and powder-coated. When pressing and molding an integral elastic centralizer, the centralizer is sleeved on the outside of the pressing mold. The top of the centralizer is limited by a pressure plate, and the pressure plate is fixedly connected to the output end of the hydraulic rod by bolts. Due to the height of the centralizer and the height of the equipment itself, the height of the connection position between the pressure plate and the output end of the hydraulic rod is relatively high. It is inconvenient to install and disassemble the pressure plate and the output end of the hydraulic rod. Moreover, the installation and disassembly of the centralizer also requires lifting it to a position higher than the top of the output end of the hydraulic rod, which also makes the installation and disassembly of the centralizer inconvenient. Based on this, an integral elastic centralizer processing equipment that facilitates flipping and loading / unloading is provided. Utility Model Content

[0007] As a further embodiment of this utility model: the limiting component includes an inner support ring block, a top annular pressure block, a counterweight ring block, an L-shaped limiting ring, and ball bearings; The top annular pressure block is fixed to the top of the inner support ring block, the counterweight ring block is distributed above the top annular pressure block, and the L-shaped limiting ring is fixed to the bottom of the counterweight ring block and passes through the top annular pressure block to the inside of the inner support ring block; The ball bearings are arranged in a ring and distributed inside the inner support ring block and protrude from the inner side of the inner support ring block.

The fixed base 105 is fixed to the top of one side of the fixed bracket 101. The worm gear reducer 106 and the drive motor 107 are fixedly installed on the top of the fixed base 105. The output end of the worm gear reducer 106 is fixedly connected to a rotating shaft 103. The output end of the drive motor 107 is connected to the input end of the worm gear reducer 106. The drive motor 107 drives the rotating shaft 103 to rotate to realize the flipping operation of the pressing component 2, thereby facilitating the loading and unloading operation of the straightener 4. The pressing assembly 2 includes a hydraulic cylinder 201, a lifting shaft 202, a convex disc seat 203, a limiting slide groove 204, a fan-shaped pressing module 205, a limiting slider 206, a vertical slide groove 207, an inclined guide groove 208, a fixing block 209, and a linkage guide column 210. Hydraulic cylinder 201 is fixedly installed at the bottom of tilting frame 104, convex disc seat 203 is fixedly installed at the top of tilting frame 104, and lifting shaft 202 is fixedly connected to the output end of hydraulic cylinder 201 and passes through tilting frame 104 and convex disc seat 203 to the top of convex disc seat 203. Multiple limiting slides 204 are provided, and the multiple limiting slides 204 are arranged in a ring on the top of the convex disk base 203; Multiple fan-shaped pressing modules 205 are provided. The multiple fan-shaped pressing modules 205 are distributed in a circle above the convex disk seat 203 and wrapped around the outside of the lifting shaft 202. The limiting slider 206 is fixed to the bottom end of the fan-shaped pressing module 205 and slidably connected to the inside of the limiting groove 204. A vertical slide groove 207 is formed inside the fan-shaped pressing module 205, and inclined guide grooves 208 are symmetrically formed on both sides of the inner wall of the fan-shaped pressing module 205. Multiple fixing blocks 209 are provided. The multiple fixing blocks 209 are arranged in a ring and fixed to the outside of the lifting shaft 202 and vertically slidably connected to the inside of the vertical slide groove 207. The linkage guide post 210 is symmetrically fixed on both sides of the fixing blocks 209 and slidably connected to the inside of the inclined guide groove 208. The centralizer 4 is sleeved on the outside of the convex disc base 203 and multiple fan-shaped pressing modules 205. The lifting shaft 202 is driven to move down by the hydraulic cylinder 201 to realize the synchronous outward movement of multiple fan-shaped pressing modules 205. The centralizer 4 is extruded and formed by the outward movement of the limiting slide groove 204. The limiting component 3 includes an inner support ring block 301, a top annular pressure block 302, a counterweight ring block 303, an L-shaped limiting ring 304, and a ball bearing 305; The top annular pressure block 302 is fixed to the top of the inner support ring block 301, the counterweight ring block 303 is distributed above the top annular pressure block 302, and the L-shaped limiting ring 304 is fixed to the bottom of the counterweight ring block 303 and passes through the top annular pressure block 302 to the inside of the inner support ring block 301. Multiple balls 305 are arranged in a ring inside the inner support ring block 301 and protrude from the inner side of the inner support ring block 301. The inner support ring block 301 has a horizontal telescopic hole for the balls 305 to move horizontally. The inner support ring block 301 and the top ring-shaped pressure block 302 have an annular groove for the L-shaped limiting ring 304 to move vertically, and the horizontal telescopic hole is connected to the annular groove. The top outer side of the lifting shaft 202 is formed with an annular groove 211. When the inner support ring block 301, the top annular pressure block 302, and the counterweight ring block 303 are sleeved on the top of the lifting shaft 202, the balls 305 are inserted into the inner side of the annular groove 211 and the L-shaped limiting ring 304 moves down to limit the outer side of the balls 305, so as to realize the connection and fixation between the inner support ring block 301 and the lifting shaft 202.
[0015] In this embodiment, the operation steps for pressing and molding the centralizer 4 are as follows: First, start the drive motor 107. Through the transmission of the worm gear reducer 106 and the rotating shaft 103, the flip frame 104 can be rotated. When the pressing assembly 2 is in a horizontal state, the drive motor 107 can be stopped. Then, the straightener 4, which is cut from seamless steel pipe, is horizontally sleeved on the outside of the convex disc base 203 and multiple fan-shaped pressing modules 205 (it should be noted that at this time, the multiple fan-shaped pressing modules 205 are in a retracted state). The second step is to connect the limiting component 3 to the lifting shaft 204, hold the counterweight ring 303 and pull up the entire limiting component 3. During this process, the counterweight ring 303 moves away from the top annular pressure block and pulls the L-shaped limiting ring 304 upward, so that the L-shaped limiting ring 304 and the ball 305 are misaligned, thereby releasing the limitation on the ball 305. The third step is to place the limiting component 3 in a horizontal position, hold it on the top annular pressure block 302, and then put the inner support ring block 301 on the outside of the lifting shaft 202. At this time, the inner support ring block 301 is inserted into the inside of the stabilizer 4. When the ball 305 contacts the lifting shaft 202, it will be forced to retract to the inside of the inner support ring block 301. This ensures that the inner support ring block 301 and the lifting shaft 202 are smoothly connected. Finally, the top annular pressure block 302 and the end face of the stabilizer 4 are tightly fitted. At this time, the position of the ball 305 is aligned with the annular groove 211. Fourth step, manually push the counterweight ring block 303 close to the top annular pressure block 302. Its L-shaped limiting ring 304 moves and squeezes the ball bearings 305, causing the ball bearings 305 to move and be inserted into the annular groove 211. This achieves the connection and fixation between the inner support ring block 301 and the lifting shaft 202 (it should be noted that the inner ring of the L-shaped limiting ring 304 completely wraps around the multiple ball bearings 305). At the same time, the installation and positioning of the stabilizer 4 are completed. Fifth step, start the drive motor 107 to run in reverse, so that the pressing component 2 is reset to the vertical state. At this time, the weight of the counterweight ring 303 can keep the L-shaped limit ring 304 in a stable downward state, thereby ensuring that the ball 305 is firmly engaged with the annular groove 211. Step 6: Start the hydraulic cylinder 201 to drive the lifting shaft 202 to move down. At this time, the lifting shaft 202 applies a squeezing force to the inclined guide groove 208 through the fixed block 209 and the linkage guide column 210. This squeezing force causes multiple fan-shaped pressing modules 205 to move outward along the trajectory of the limiting slide groove 204. The outward moving fan-shaped pressing modules 205 will squeeze the middle part of the straightener 4. At the same time, the lifting shaft 202 synchronously drives the limiting component 3 to move down to squeeze the top of the straightener 4, which in turn causes the middle part of the straightener 4 to bend and deform outward. Finally, the shape of the middle part of the straightener 4 matches the outer shape of the fan-shaped pressing module 205. At this time, the pressing and forming of the straightener 4 is completed. Step 7: Reverse start hydraulic cylinder 201 to reset it, and start drive motor 107 to flip pressing component 2 to horizontal state again. Then pull counterweight ring block 303 away from top annular pressure block 302. L-shaped limit ring 304 synchronously displaces and contacts the limit of ball 305. Then continue to pull, ball 305 is compressed under force, causing inner support ring block 301 to separate from lifting shaft 202, thereby realizing convenient disassembly of limit component 3. Then the formed stabilizer 4 can be removed. At this time, the pressing of a single stabilizer 4 is completed. Repeat the above steps to achieve batch pressing of stabilizers 4. The efficient pressing operation of the centralizer 4 can be achieved through the cooperation of the above-mentioned parts. Compared with the traditional pressing components that cannot be flipped, the centralizer 4 is easier to disassemble and assemble, which can effectively improve the working efficiency of the pressing process of the centralizer 4.
[0016] Please refer to this carefully. Figures 1-6 The outer diameter of the top of the convex disc base 203 and the outer diameter of the inner support ring block 301 are matched with the inner diameters of the upper and lower ends of the centralizer 4, and the outer diameter of the top ring pressure block 302 is larger than the outer diameter of the centralizer 4.
[0017] In this embodiment, this structure ensures that when the middle part of the straightener 4 is squeezed by the fan-shaped pressing module 205, the upper and lower ends of the straightener 4 remain undeformed, thereby maintaining the molding stability of the straightener 4.
[0018] Please refer to this carefully. Figures 1-4 There is a height difference between the top of the fan-shaped pressing module 205 and the annular slot 211.
[0019] In this embodiment, this structure provides space for the downward movement of the limiting component 3, and the downward movement of the limiting component 3 will not cause contact or collision with the fan-shaped pressing module 205.
[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
