Description

Technical Field

[0001] This utility model relates to the field of oil extraction accessories technology, and in particular to an auxiliary processing device for smooth rod sealing filler. Background Technology

[0002] In the petroleum industry, pumping wells have always been the main method of oil production in oil fields both at home and abroad. The pumping unit, sucker rod, and pump are the three main components of rod pump oil production equipment. The sucker rod is the component that transmits the movement and power of the pumping unit to the downhole pump for pumping. The polished sucker rod is a special sucker rod at the top of the sucker rod string, which is used to cooperate with the wellhead sealing box to seal the wellhead.

[0003] In the prior art, such as the Chinese patent publication number CN212079231U, a wear-resistant polished rod for oil extraction is disclosed, comprising a wear-resistant polished rod body. The wear-resistant polished rod body includes a bottom chamfer, an upper transition section, a rod head shoulder, an anti-corrosion block, a wrench fitting neck, a polished rod end block, a polished rod base, outer wall ribs, and an outer wear-resistant layer. The lower side of the wear-resistant polished rod body has a bottom chamfer. The upper side of the wear-resistant polished rod body is fixedly connected to the upper side of the upper transition section. The upper side of the upper transition section is fixedly connected to the rod head shoulder. An anti-corrosion block is installed at the middle left side of the outer wall of the rod head shoulder. A wrench fitting neck is fixedly installed at the middle upper side of the rod head shoulder. The polished rod end block is fixedly installed at the upper side of the wrench fitting neck. The polished rod base is installed inside the wear-resistant polished rod body. The overall equipment has a simple structure, is easy to operate, has rich functions, and has high stability and practicality, and has certain promotional value.

[0004] When processing the polished rod of an oil pumping unit, the polished rod sealing packing is a large sheet of sealing plastic. It needs to be cut into strips to wrap the polished rod, increasing its toughness and making it easier to manually install the sealing packing on the polished rod. Therefore, an auxiliary processing device for polished rod sealing packing is needed to cut the sealing packing. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary processing device for smooth rod sealing filler, which has the effect of cutting sealing filler into strips.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an auxiliary processing device for smooth rod sealing filler, comprising a processing plate, a first support platform provided at the top edge of the processing plate, a threaded cylinder fixedly connected to the top of the first support platform, a threaded shaft threadedly connected inside the threaded cylinder, a cavity opened at the end of the threaded shaft, an insert rod inserted inside the cavity, a limit ring fixedly connected to the middle of the insert rod, a processing rod fixedly connected to one end of the insert rod, a helical blade fixedly connected to the outside of the processing rod, an insertion hole opened inside the insert rod, a screw threadedly connected to the end of the threaded shaft, a nut threadedly connected to the outside of the screw, and a cutting mechanism provided at the top of the processing plate.

[0007] By adopting the above technical solution, the sealing filler is wound around the spiral blades on the outside of the processing rod. The spiral blades are distributed in a spiral form on the outside of the processing rod, with gaps between each segment of the spiral blades. Then, the insertion rod is inserted into the end of the threaded shaft, and the screw passes through the threaded cylinder and the threaded shaft. The nut is threaded to both ends of the screw, so that the threaded shaft can be fixed to the end of the threaded cylinder. The sealing filler on the outside of the processing rod is cut by a cutting mechanism. The cutting blade of the cutting mechanism contacts the sealing filler and extends into the gaps between each segment of the spiral blades, thereby making contact with the sealing filler. During this process, the threaded shaft is rotated, causing the threaded shaft to move inside the threaded cylinder. Through the movement of the threaded shaft, the sealing filler wound around the outside of the processing rod is cut into straight strips, thereby completing the auxiliary processing of the sealing filler.

[0008] A further feature of this invention is that a second support platform is provided on the top of the processing plate, and a support ring is fixedly connected to the top of the second support platform.

[0009] By adopting the above technical solution, when the threaded shaft drives the processing rod to move, the sealing packing outside the processing rod is supported by the support ring.

[0010] A further feature of this invention is that a slide rail is fixedly connected to the top edge of the processing plate, and a slider is slidably connected inside the slide rail, with the first support platform fixedly connected to the top of the slider.

[0011] By adopting the above technical solution, the first support platform is moved, so that the first support platform can be displaced inside the slide rail by the slider, thereby displacing the position of the processing rod and bringing the processing rod closer to the cutting mechanism.

[0012] A further feature of this invention is that a connecting rod is fixedly connected between the first support platform and the second support platform.

[0013] By adopting the above technical solution, the first support platform and the second support platform are fixed together by a connecting rod, and the first support platform drives the second support platform to move synchronously.

[0014] A further feature of this invention is that pulleys are rotatably connected to both sides of the outer side of the second support platform, and the number of pulleys is four.

[0015] By adopting the above technical solution, during the movement of the second support platform, the pulley supports the second support platform, and the pulley moves on the top of the processing plate.

[0016] A further feature of this invention is that a rectangular groove is provided on the outer side of the slide rail, and a locking rod is fixedly connected to the outer side of the slider.

[0017] By adopting the above technical solution, the locking rod will move inside the rectangular groove during the displacement process of the slider.

[0018] A further feature of this invention is that the locking rod has a locking ring connected to its external thread.

[0019] By adopting the above technical solution, the locking ring is twisted, causing it to move outside the locking rod. The locking ring then contacts the outer wall of the slide rail, thereby locking the slider and fixing the first support platform.

[0020] A further feature of this invention is that a handle is fixedly connected to one end of the threaded shaft, and an anti-slip sleeve is fixedly connected to the outside of the handle.

[0021] By adopting the above technical solution, it is more convenient to hold the handle and rotate the threaded shaft.

[0022] A further feature of this invention is that the cutting mechanism includes a cutting box, a cylinder is fixedly mounted on the top of the cutting box, and a cutting blade is fixedly connected to the output end of the cylinder.

[0023] By adopting the above technical solution, the cylinder drives the cutting blade to extend and retract, and the extension and retraction of the cutting blade makes the cutting blade come into contact with the sealing filler.

[0024] A further feature of this invention is that an electric slide rail is fixedly installed on the top of the processing plate, and the cutting mechanism is fixedly connected to the output end of the electric slide rail.

[0025] By adopting the above technical solution, the electric slide rail drives the cutting mechanism to move, thereby enabling the adjustment of the position of the cutting mechanism.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a processing plate, a first support platform, a threaded cylinder, a threaded shaft, an insert rod, a limiting ring, a processing rod, helical blades, an insertion hole, a screw, a nut, and a cutting mechanism, allows the sealing filler to be wound around the helical blades outside the processing rod. The helical blades are distributed in a helical form on the outside of the processing rod, with gaps between each segment of the helical blades. Then, the insert rod is inserted to the end of the threaded shaft, and the screw passes through the threaded cylinder and the threaded shaft. The nut is threaded to both ends of the screw, so that the threaded shaft can be fixed to the end of the threaded cylinder. The cutting mechanism cuts the sealing filler outside the processing rod. The cutting blade of the cutting mechanism contacts the sealing filler and extends into the gaps between each segment of the helical blades, thus making contact with the sealing filler. During this process, the threaded shaft is rotated, causing the threaded shaft to move inside the threaded cylinder. Through the movement of the threaded shaft, the sealing filler wound around the outside of the processing rod is cut into straight strips, thereby completing the auxiliary processing of the sealing filler.

[0028] 2. In this utility model, through the arrangement of the second support platform, the ring support, the slide rail, the slider, the connecting rod, and the pulley, when the threaded shaft drives the processing rod to move, the ring support supports the sealing filler outside the processing rod. The first support platform moves, so that the first support platform moves inside the slide rail through the slider, thereby moving the position of the processing rod so that the processing rod is closer to the cutting mechanism. The first support platform and the second support platform are fixed by the connecting rod. The first support platform drives the second support platform to move synchronously. During the movement of the second support platform, the pulley supports the second support platform, and the pulley travels on the top of the processing plate. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Reference Figure 1-4 An auxiliary processing device for smooth rod sealing filler includes the following specific embodiments:

[0037] Example 1: An auxiliary processing device for a smooth rod sealing filler includes a processing plate 1. A first support platform 2 is provided at the top edge of the processing plate 1. A threaded cylinder 3 is fixedly connected to the top of the first support platform 2. A threaded shaft 4 is threadedly connected inside the threaded cylinder 3. A handle 22 is fixedly connected to one end of the threaded shaft 4. An anti-slip sleeve 23 is fixedly connected to the outside of the handle 22, making it convenient to rotate the threaded shaft 4 by holding the handle 22. A cavity is opened at the end of the threaded shaft 4, and an insert rod 5 is inserted into the cavity. A limit ring 6 is fixedly connected to the middle of the insert rod 5. A processing rod 7 is fixedly connected to one end of the insert rod 5. A spiral blade 8 is fixedly connected to the outside of the processing rod 7. An insertion hole 9 is opened inside the insert rod 5. A screw 10 is threadedly connected to the end of the threaded shaft 4. A nut 11 is threadedly connected to the outside of the screw 10. A cutting mechanism 12 is provided at the top of the processing plate 1 to wrap the sealing filler around the processing plate 1. On the outer spiral blades 8 of the processing rod 7, the spiral blades 8 are distributed in a spiral form on the outside of the processing rod 7, with gaps between each spiral blade segment 8. Then, the insertion rod 5 is inserted into the end of the threaded shaft 4, and the screw 10 passes through the threaded cylinder 3 and the threaded shaft 4. The nut 11 is threaded to both ends of the screw 10, so that the threaded shaft 4 can be fixed to the end of the threaded cylinder 3. The cutting mechanism 12 cuts the sealing filler on the outside of the processing rod 7. The cutting blade of the cutting mechanism 12 contacts the sealing filler and extends into the gap between each spiral blade segment 8, thereby contacting the sealing filler. During this process, the threaded shaft 4 is rotated, so that the threaded shaft 4 moves inside the threaded cylinder 3. Through the movement of the threaded shaft 4, the sealing filler wrapped around the outside of the processing rod 7 is cut into straight strips, thereby completing the auxiliary processing of the sealing filler.

[0038] Example 2: A second support platform 13 is provided on the top of the processing plate 1. A support ring 14 is fixedly connected to the top of the second support platform 13. When the threaded shaft 4 drives the processing rod 7 to move, the support ring 14 supports the sealing packing outside the processing rod 7. A slide rail 15 is fixedly connected to the edge of the top of the processing plate 1. A slider 16 is slidably connected inside the slide rail 15. A first support platform 2 is fixedly connected to the top of the slider 16. Moving the first support platform 2 causes it to move inside the slide rail 15 via the slider 16, thereby moving the position of the processing rod 7 so that the processing rod 7 is closer to the cutting mechanism 12. A connecting rod 17 is fixedly connected between the first support platform 2 and the second support platform 13. The first support platform 2 and the second support platform 13 are fixed together by the connecting rod 17. The support platform 2 drives the second support platform 13 to move synchronously. The two sides of the second support platform 13 are rotatably connected to pulleys 18, and there are four pulleys 18. During the movement of the second support platform 13, the pulleys 18 support the second support platform 13 and travel on the top of the processing plate 1. The outer side of the slide rail 15 is provided with a rectangular groove 19. The outer side of the slider 16 is fixedly connected with a locking rod 20. During the displacement of the slider 16, the locking rod 20 will move inside the rectangular groove 19. The locking rod 20 is threadedly connected to a locking ring 21. Twisting the locking ring 21 causes the locking ring 21 to move outside the locking rod 20. The locking ring 21 contacts the outer wall of the slide rail 15, thereby locking the slider 16 and achieving the effect of fixing the first support platform 2.

[0039] Example 3: The cutting mechanism 12 includes a cutting box 121. A cylinder 122 is fixedly installed on the top of the cutting box 121. A cutting blade is fixedly connected to the output end of the cylinder 122. The cylinder 122 drives the cutting blade to extend and retract. Through the extension and retraction of the cutting blade, the cutting blade contacts the sealing filler. An electric slide rail 24 is fixedly installed on the top of the processing plate 1. The cutting mechanism 12 is fixedly connected to the output end of the electric slide rail 24. The electric slide rail 24 drives the cutting mechanism 12 to move, thereby adjusting the position of the cutting mechanism 12.

[0040] In this invention, sealing filler is wound around the spiral blades 8 on the outside of the processing rod 7. The spiral blades 8 are distributed in a spiral pattern on the outside of the processing rod 7, with gaps between each segment of the spiral blades 8. Then, the insertion rod 5 is inserted into the end of the threaded shaft 4, and the screw 10 passes through the threaded cylinder 3 and the threaded shaft 4. The nut 11 is threaded to both ends of the screw 10, so that the threaded shaft 4 can be fixed to the end of the threaded cylinder 3. The sealing filler on the outside of the processing rod 7 is cut by the cutting mechanism 12. The cutting blade of the cutting mechanism 12 contacts the sealing filler and extends into the gaps between each segment of the spiral blades 8, thereby contacting the sealing filler. During this process, the threaded shaft 4 is rotated, causing the threaded shaft 4 to move inside the threaded cylinder 3. The movement of the threaded shaft 4 causes the sealing filler wrapped around the processing rod 7 to be cut into straight strips, thereby completing the auxiliary processing of the sealing filler. When the threaded shaft 4 drives the processing rod 7 to move, the sealing filler outside the processing rod 7 is supported by the support ring 14. The first support platform 2 is moved so that the first support platform 2 moves inside the slide rail 15 through the slider 16, thereby moving the position of the processing rod 7 so that the processing rod 7 is close to the cutting mechanism 12. The first support platform 2 and the second support platform 13 are fixed together by the connecting rod 17. The first support platform 2 drives the second support platform 13 to move synchronously. During the movement of the second support platform 13, the pulley 18 supports the second support platform 13 and the pulley 18 moves on the top of the processing plate 1.
