Description

Technical Field

[0001] The present invention relates to the application field of liner cementing, and in particular to an automatic scraping and diameter-cutting integrated machine device for running a tool. Background Art

[0002] After the liner cementing operation is completed, the running tool is taken out together with the drilling tool. After on-site recovery, the running tool needs to be maintained and dredged to remove cement blocks, cement rings, hard wax, various salt crystals or sediments, perforation burrs, and solid dirt such as iron oxide produced by rust on the inner wall of the running tool. The inner wall of the running tool is smooth and unobstructed to ensure the secondary use of the running tool.

[0003] At present, manual work is usually used to clear the feeding tool and remove cement blocks in the inner tube with extended steel wire balls. This is not only time-consuming and labor-intensive, but also has low efficiency and high labor intensity. In addition, the cleaning is not thorough and the effect is not good, which consumes a lot of manpower, material and financial resources and increases the cost of the operation.

[0004] In addition, the length of the feeding tool is relatively long, generally 8 to 12 meters. If the cement blocks, cement rings, hard wax, etc. on the inner wall of the feeding tool are large in volume or hardness, it is difficult to clean them directly with an extended steel wool. It is difficult to completely remove stubborn cement stones and other residues, which affects the diameter effect.

[0005] Therefore, it is desired in the art to provide an automatic scraping and diameter-cutting integrated machine device for feeding tools to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to propose an automatic scraping and dredging machine device for a running tool, which is mainly used for maintaining the diameter of the running tool in the tail pipe hanger, and integrates the scraping, cleaning, dust suction, dust collection and dredging functions into one, thereby effectively solving the problems of low efficiency and poor effect of manual dredging, and can effectively improve the dredging efficiency and cleaning effect, further ensure the smooth and beautiful inner wall of the running tool and the subsequent painting operation, so as to ensure that the running tool can be reused multiple times.

[0008] a scraping mechanism disposed above the driving mechanism and connected to the first transmission shaft, and

[0009] A dust removal mechanism is provided below the driving mechanism and connected to the second transmission shaft.

[0010] In one embodiment, the scraping mechanism includes a body connected to the output end of the first transmission shaft, and a scraper sleeved on the outside of the body and in contact with the inner wall of the feeding tool.

[0011] In one embodiment, the scraper is made of cemented carbide material.

[0012] In one embodiment, a brush for scraping off debris attached to the inner wall of the feeding tool is provided between the driving mechanism and the dust removal mechanism.

[0013] In one embodiment, the brush is composed of a plurality of 0.3-0.5 mm copper-plated steel wires.

[0014] In one embodiment, the brush is fixed to the second transmission shaft by bolts.

[0015] In one embodiment, the dust removal mechanism includes a dust box arranged below the brush, a suction brush nested on the dust box and used to receive the debris, a dust pipe arranged in the dust box and connected to the suction brush, and a dust collecting box arranged below the dust box and connected to the dust pipe.

[0016] In one embodiment, a dust collection motor is provided in the dust collection box, and the dust collection motor is constructed as a unidirectional AC / DC dual-purpose series-excited motor.

[0017] In one embodiment, the driving mechanism includes a driving body arranged between the first transmission shaft and the second transmission shaft, and crawling wheels are provided on the outer sides of the driving body and the dust box.

[0018] In one embodiment, the automatic scraping integrated machine device further includes a driving battery fixedly mounted on the bottom of the dust box, and the driving battery is connected to the crawler wheel via a cable.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] First, the present invention is mainly used for maintaining the diameter of the running tool in the liner hanger, and integrates the functions of scraping, cleaning, dust suction, dust collection and diameter clearance into one, thereby effectively solving the problems of low efficiency and poor effect of manual diameter clearance, thereby effectively improving the diameter clearance efficiency and cleaning effect, further ensuring the smooth and beautiful inner wall of the running tool and the subsequent painting operation, so as to ensure that the running tool can be reused multiple times.

[0021] Secondly, the present invention can use an electric brush to grind the inner wall of the feeding tool while scraping, and can automatically collect the polished cement debris through the dust suction component and the dust collection component, thereby avoiding direct contact between the operator and the harmful substances in the feeding tool, so as to reduce the risk of operational accidents and enhance operational safety. In this way, not only the health of the operators can be guaranteed, but also a clean working environment can be ensured in the entire workshop.

[0022] Third, the present invention can replace or adopt scrapers and brushes of different sizes according to the changes in the inner diameter of the pulling short section and the center tube in different feeding tools, thereby effectively expanding the application range of the scraping mechanism and the grinding mechanism, so as to help to carry out comprehensive cleaning work on the inner wall of the tool, and further improve the practicality of the device.

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] Figure 1 The structure of the automatic scraping and diameter-cutting integrated machine device 100 for feeding a tool according to the present invention is schematically shown;

[0039] Figure 2 It is a partial view in the figure, which schematically shows the specific structure of the scraping mechanism;

[0040] Figure 3 The schematic diagram shows the layout position of the present invention in the running tool 101.

[0041] like Figures 1 to 3 As shown, the automatic scraping and dredging integrated device 100 for feeding tools according to the present invention primarily comprises a drive mechanism, a scraping mechanism, and a dust removal mechanism arranged in series within a feeding tool 101. Preferably, the drive mechanism comprises a drive body 10, and first and second transmission shafts 11, 12 disposed at opposite ends of the drive body 10. Preferably, the scraping mechanism and dust removal mechanism are connected to the first and second transmission shafts 11, 12, respectively, as described below.

[0042] Preferably, the scraping mechanism is arranged above the driving mechanism and can be fixedly connected to the first transmission shaft 11. Therefore, the scraping mechanism can rotate under the driving action of the first transmission shaft 11, so that the inner wall of the feeding tool 101 can be scraped in all aspects more quickly.

[0043] In one embodiment, Figure 1 and 2As shown, the scraping mechanism includes a body 21 connected to the output end of the first transmission shaft 11, and a scraper 22 sleeved on the body. Preferably, the scraper 22 is constructed as a spiral scraper, and the scraper 22 rotates under the action of the first transmission shaft 11, thereby being able to fully remove cement blocks, cement rings, hard wax, various salt crystals or sediments, perforation burrs, and iron oxide generated by rust on the running tool 101, etc., which further facilitates the secondary use of the running tool 101.

[0044] Preferably, the scraper 22 is made of a cemented carbide material. The cemented carbide material in the present invention is tungsten steel. Tungsten steel, also known as cemented carbide, refers to a sintered composite material composed of at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, and tantalum carbide are common components of tungsten steel. The grain size of the carbide component (or phase) is usually between 0.2 and 10 microns, and the carbide grains are bonded together using a metal binder. The binder usually refers to metal cobalt (Co), but for some special applications, nickel (Ni), iron (Fe), or other metals and alloys can also be used.

[0045] In addition, tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500°C, and it still has a high hardness at 1000°C. Therefore, the scraper 22 can smoothly complete the scraping work in the feeding tool 101.

[0046] In a preferred embodiment of the present invention, since the inner diameters of different feeding tools 101 may be different, the present invention can appropriately and reasonably adjust the scraping size of the scraper 22 based on the changes in the inner diameters of the pulling short sections and the central tubes in different feeding tools 101, thereby effectively expanding the application range of the scraping mechanism.

[0047] In one embodiment, Figure 1 As shown, a grinding mechanism is provided between the driving mechanism and the dust removal mechanism. The grinding mechanism is configured as a brush 31. Preferably, the brush 31 is fixed to the second transmission shaft 12 by bolts, so that the brush 31 can move synchronously with the second transmission shaft 12 (i.e., rotate).

[0048] Preferably, since the device moves gradually from the bottom end to the top end of the feeding tool 101 during operation, the brush 31 can scrape and polish the debris attached to the inner wall of the feeding tool 101, thereby causing the debris to fall smoothly, thereby facilitating the subsequent recovery work of the dust removal mechanism.

[0049] Preferably, the brush 31 is made of multiple high-density uniform steel wire brushes, so it has strong wear resistance, so that it can more easily clean the debris attached to the inner wall of the feeding tool 101, to ensure that the feeding tool 101 can be put into production again smoothly after cleaning.

[0050] Preferably, the wire brushes in the present invention are made of 0.3-0.5 mm copper-plated steel wire, which can ensure the firmness of the brush 31 during the cleaning process and is not prone to falling off or breaking, thereby further improving the cleaning efficiency and cleaning quality.

[0051] In a preferred embodiment of the present invention, since the inner diameters of different feeding tools 101 may vary, the present invention can appropriately adjust the size of the brush 31 based on the changes in the inner diameters of the pulling short sections and the central tubes in different feeding tools 101, thereby improving the practicality of the automatic scraping and diameter-clearing integrated machine device 100 for the feeding tool.

[0052] Preferably, the dust removal mechanism is arranged below the driving mechanism and the brush 31, and the dust removal mechanism is fixedly connected to the second transmission shaft 11, so that the dust removal mechanism can more easily receive the debris cleaned up by the scraping mechanism and the brush 31 under the action of the second transmission shaft 11, so as to further realize the integrated scraping and recycling function.

[0053] According to the present invention, the dust removal mechanism includes a dust suction component and a dust collection component matched with the dust suction component. The dust suction component will be mainly introduced below. Figure 1 As shown, the dust collection assembly includes a dust collection box 41 connected to the second transmission shaft 12, and a suction brush 42 nested on the outer wall of the dust collection box 41. Preferably, the suction brush 42 can guide the direction of the debris cleaned by the scraping mechanism and the brush 31, thereby facilitating the recovery work of the dust removal mechanism.

[0054] Preferably, if Figure 1 As shown, a dust collection tube 43 is provided in the dust collection box 41. The two ends of the dust collection tube 43 are respectively connected to the suction brush 42 and the dust collection box 44 (introduced below), so as to ensure that the debris cleaned by the scraping mechanism and the brush 31 can smoothly enter the dust collection box 44.

[0055] In one embodiment, Figure 1 As shown, a dust collection motor 431 is provided within the dust collection box 41 to ensure the normal operation of the dust collection assembly and to provide a constant dust collection effect. The dust collection motor 431 in the present invention is a unidirectional AC / DC dual-purpose series-excited motor. This motor has the advantages of high speed, compact size, high starting torque, and adjustable speed, thereby enhancing the cleaning performance within the feed tool 101.

[0056] In one embodiment, an exhaust fan (not shown) is provided in the dust box 41 and is matched with the dust suction motor 431. Preferably, a fan impeller is provided on the exhaust fan, which can rotate under the driving action of the dust suction motor 431 to recover debris.

[0057] Preferably, after exhausting the air, the exhaust fan will generate extremely strong suction and pressure, and the air will be discharged at a high speed under the action of suction and pressure, and the air in the dust collection part of the front section of the exhaust fan continuously replenishes the air in the fan, causing an instantaneous vacuum to be generated inside the dust collection component, forming a negative pressure difference with the external atmospheric pressure. Therefore, under the action of this pressure difference, debris containing cement blocks, cement rings, etc. cleaned by the scraping mechanism and the brush 31 can be more easily sucked in.

[0058] In one embodiment, the dust collection assembly is configured as a dust box 44. Preferably, the dust box 44 is positioned below the dust collection box 41 and is connected to the dust collection box 41 via a dust collection tube 43. Consequently, debris removed by the scraping mechanism and brush 31 passes through the suction brush 42 and the dust collection tube 43 and enters the dust box 44. Preferably, once the dust box 44 is full, it can be removed and cleaned, thereby achieving recycling.

[0059] In one embodiment, Figure 1 As shown, crawling wheels 13 are provided on the outer sides of the driving body 10 and the dust box 44. Preferably, the crawling wheels 13 can abut against the inner wall of the feeding tool 101, thereby ensuring that the automatic scraping diameter integrated machine device 100 can crawl upward while cleaning, thereby completing the cleaning work.

[0060] In one embodiment, Figure 1 As shown, the automatic scraping and dredging device 100 for feeding a tool further includes a drive battery 32 fixedly mounted at the bottom of the dust box 44. Preferably, the drive battery 32 is connected to the crawler wheel 13 via a cable. In the present invention, the drive battery 32 can drive the crawler wheel 13, thereby enabling the automatic scraping and dredging device 100 to smoothly crawl upward within the feeding tool 101.

[0061] Figure 3 The schematic diagram shows the layout position of the present invention in the running tool 101.

[0062] Combine Figures 1 to 3 The working process of this device is introduced below:

[0063] First, the automatic scraping and diameter-cutting integrated machine device 100 for feeding the tool needs to be placed into the feeding tool 101 (bottom) from the end of the lifting short section;

[0064] Then, the driving body 10 drives the first transmission shaft 11 and the second transmission shaft 12 to rotate, further driving the scraper 22 and the brush 31 to rotate to scrape and polish the inner wall of the feeding tool 101;

[0065] Afterwards, the operating speed of the crawling wheel 13 is controlled by the driving battery 32 to cause the automatic scraping and diameter-clearing integrated machine device 100 to crawl upward in the feeding tool 101;

[0066] Finally, the device will crawl out from the top of the running tool 101, and the entire cleaning process is completed.

[0067] Compared with the prior art, the advantages of the present invention are:

[0068] First, the present invention is primarily used for maintaining the flow path of the running tool 101 in the liner hanger. It integrates scraping, cleaning, vacuuming, dust collection, and flow path functions into one, effectively solving the problems of low efficiency and poor results of manual flow path maintenance. This effectively improves flow path efficiency and cleaning effects, further ensuring a smooth and beautiful inner wall of the running tool 101 and subsequent painting operations, thereby ensuring that the running tool 101 can be reused multiple times.

[0069] Secondly, the present invention can use an electric brush 31 to grind the inner wall of the feeding tool 101 while scraping, and can automatically collect the polished cement debris through the dust suction component and the dust collection component, thereby avoiding direct contact between the operator and the harmful substances in the feeding tool 101, so as to reduce the risk of operational accidents and enhance operational safety. In this way, not only the health of the operators can be guaranteed, but also a clean working environment can be ensured in the entire workshop.

[0070] Third, the present invention can replace or adopt scrapers 22 and brushes 31 of different sizes according to the changes in the inner diameter of the pulling short section and the center tube in different feeding tools 101, thereby effectively expanding the application range of the scraping mechanism and the grinding mechanism, so as to help to carry out comprehensive cleaning work on the inner wall of the tool, and further improve the practicality of the device.

[0071] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art may easily make changes or modifications within the scope of the present invention, and such changes or modifications should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
