Description

Technical Field

[0001] This invention relates to the field of electrolytic production technology, specifically a hoisting structure and an EP tube electrolytic production device containing the structure. Background Technology

[0002] Electropolished tubes (EP tubes) are metal tubes treated with an electropolishing process. This process uses electrochemical dissolution to preferentially dissolve microscopic protrusions on the surface, thereby obtaining ultra-high smoothness (Ra as low as 0.02-0.1μm), a pure surface (removal of oxide layer and impurities), and enhanced corrosion resistance (formation of a uniform passivation film). At the same time, it has excellent fluid properties. Electrolytic production equipment refers to a complete set of equipment that realizes industrial production processes such as material preparation, purification, and surface treatment through the principle of electrolysis (i.e., using direct current to drive the electrolyte solution or molten electrolyte to undergo oxidation-reduction reaction).

[0003] Existing electrolytic production equipment typically uses ropes or clamps to simultaneously hoist multiple pipes via a gantry crane and place them in an electrolytic cell. The electrolytic polishing process (EP pipe) is then performed using the electrolyte in the cell. However, during electrolysis, if multiple pipes come into contact with each other, a low-resistance conductive path is formed at the contact point, leading to abnormal local current distribution (a sudden increase in current density at the contact point and insufficient current in the surrounding area). This results in excessive dissolution at the contact points, forming defects such as depressions and pinholes, while the surrounding areas remain undissolved, leaving protrusions. This causes increased surface roughness, contact marks, and corrosion spots. Furthermore, the contact between pipes disrupts the uniformity of the electric field, leading to significant differences in the polishing degree of pipes in the same batch and a decrease in overall processing consistency. Based on this, a hoisting structure and an EP pipe electrolytic production device incorporating this structure are provided to eliminate the drawbacks of existing equipment. Summary of the Invention

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] In one embodiment, such as Figures 1-8As shown, a hoisting structure includes a movable seat 1, a first movable frame 4 is provided below the movable seat 1, a second movable frame 6 is provided on the lower surface of the first movable frame 4, a support plate 5 is provided at one end of the movable seat 1, a second servo motor 7 is installed at the end of the support plate 5 away from the movable seat 1, a transmission screw 9 is fixedly connected to the output end of the second servo motor 7, two second limiting rods 8 are symmetrically arranged on the outer side of the transmission screw 9, both second limiting rods 8 are fixedly connected to the support plate 5, the movable seat 1 is slidably sleeved on the outer wall of the two second limiting rods 8, the movable seat 1 is sleeved on the outer wall of the transmission screw 9, the movable seat 1 is threadedly connected to the transmission screw 9, and a separation mechanism for separating multiple pipe fittings is provided on the second movable frame 6.

[0047] The separation mechanism includes: two connecting slide plates 207 symmetrically arranged below the second movable frame 6; two movable sliders 206 are symmetrically fixedly connected to the top of each of the two connecting slide plates 207; two rollers are symmetrically rotatably connected to the outer walls of each of the two movable sliders 206; the movable sliders 206 and the rollers are slidably connected to the second movable frame 6; multiple positioning hooks 203 are equidistantly arranged at the bottom of the two connecting slide plates 207; the multiple positioning hooks 203 are all L-shaped; the multiple positioning hooks 203 penetrate into the interior of the connecting slide plates 207; and sliding sleeves 2012 are fixedly connected to the top of each of the multiple positioning hooks 203; the positioning hooks 203 and the sliding sleeves 2012 are slidably connected to the connecting slide plates 207.

[0048] The movable base 1 is equipped with a retraction mechanism for driving the first movable frame 4 to rise, fall, and tilt.

[0049] It also includes a connecting bracket 10, a movable seat 1 located inside the connecting bracket 10, a support plate 5 fixedly connected to the connecting bracket 10, an electrolytic cell 11 and a cleaning tank 12 provided inside the connecting bracket 10, the electrolytic cell 11 located below one end of the movable seat 1, the cleaning tank 12 located at the end of the electrolytic cell 11 away from the movable seat 1, and a placement platform 13 provided below the second movable frame 6, the placement platform 13 being C-shaped.

[0050] In this embodiment, multiple pipes are placed on the upper surface of the placement platform 13. Then, through the take-up and release mechanism, the second moving frame 6, the first moving frame 4, and the separation mechanism, multiple positioning hooks 203 can be moved to the ends of the multiple pipes and clamped. Then, the take-up and release mechanism drives the first moving frame 4 to rise. At this time, the multiple pipes are separated from the upper surface of the placement platform 13 under the drive of the positioning hooks 203. Then, the second servo motor 7 is started to drive the transmission screw 9 to rotate. At this time, the moving seat 1 slides along the outer wall of the transmission screw 9 under the drive of the thread of the transmission screw 9, so that the pipes can be transported to the top of the electrolytic cell 11 for convenient hoisting of multiple pipes.

[0051] At this time, the separation mechanism pushes the second moving frame 6 to separate from the first moving frame 4, and the spacing between multiple pipes can be easily adjusted, effectively avoiding damage, scars and uneven smoothness on the surface of the pipes due to contact between their outer walls during the electrolysis process.

[0052] Simultaneously, through the unwinding operation of the winding mechanism, one side of the first moving frame 4 can be lowered. At this time, the second moving frame 6, driven by the first moving frame 4, lowers one end of the pipe fitting, thereby making the pipe fitting as a whole tilted. Then, the winding mechanism makes multiple pipe fittings enter the inner cavity of the electrolytic tank 11 in an tilted state. Since multiple pipe fittings are in a tilted state at this time, the electrolyte can fully contact the inner wall of the pipe fitting, effectively avoiding the situation where the electrolyte cannot contact the inner wall of the pipe fitting due to air bubbles, etc. When the electrolysis operation of the pipe fitting is completed, the pipe fitting is placed in the inner cavity of the cleaning tank 12 through winding and unwinding, thereby removing the residual electrolyte on the surface of the pipe fitting and preventing the residual electrolyte from corroding the pipe fitting.

[0053] In one embodiment, such as Figures 2-8 As shown, the separation mechanism also includes an adjustment component disposed on the connecting slide plate 207;

[0055] The second movable frame 6 is equipped with a drive assembly for driving the movement of the connecting slide plate 207;

[0056] The first movable frame 4 is provided with a separation component for pushing the second movable frame 6 to separate from the first movable frame 4;

[0057] The sliding sleeve 2012 is provided with a transmission component for driving the adjusting rod 2013 to rotate;

[0058] The drive assembly includes: a first servo motor 2015 installed inside the second moving frame 6; a bevel gear 2014 fixedly connected to the output end of the first servo motor 2015; a bevel gear ring 2010 meshing with the outer wall of the bevel gear 2014; a bidirectional lead screw 205 rotatably connected inside the second moving frame 6; the bevel gear ring 2010 fixedly connected to the outer wall of the bidirectional lead screw 205; two moving sleeves 208 symmetrically sleeved on the outer wall of the bidirectional lead screw 205; the two moving sleeves 208 are respectively located at the top of two connecting slide plates 207; the two moving sleeves 208 are respectively fixedly connected to the two connecting slide plates 207; and both moving sleeves 208 are slidably connected to the second moving frame 6.

[0059] The separation assembly includes: a hydraulic push rod 2017 installed on the top of the first movable frame 4; a second movable frame 6 fixedly connected to the output end of the hydraulic push rod 2017; two connecting sliders 201 symmetrically fixedly connected to the top of the second movable frame 6; the two connecting sliders 201 are respectively located above the two connecting slide plates 207; the connecting sliders 201 are located between the two movable sliders 206; the first movable frame 4 is slidably sleeved on the outer wall of the two connecting sliders 201; multiple lifting slide rods 2018 are longitudinally and equidistantly arranged inside the two connecting sliders 201; the multiple lifting slide rods 2018 all pass through the connecting sliders 201 and are fixedly connected to the first movable frame 4; a movable groove for the lifting slide rods 2018 to slide is opened at the contact position between the connecting sliders 201 and the multiple lifting slide rods 2018.

[0060] The transmission assembly includes: two spur gears 204 fixedly connected to both ends of the adjusting rod 2013, two movable sliders 206 located between the two spur gears 204, both spur gears 204 being rotatably connected to the connecting slide plate 207, and racks 209 meshing with the outer walls of both spur gears 204. The racks 209 penetrate the interior of the connecting slide plate 207, the second movable frame 6, and the first movable frame 4. The racks 209 are slidably connected to the connecting slide plate 207, the second movable frame 6, and the first movable frame 4. A limit slider 202 is fixedly connected to the top of the racks 209. The limit slider 202 is slidably connected to the first movable frame 4. Through the cooperation of the adjusting assembly, the driving assembly, the separating assembly, and the transmission assembly, the spacing between multiple pipes can be conveniently adjusted, effectively preventing multiple pipes from contacting each other during electrolysis.

[0061] In one embodiment, such as Figures 2-6 As shown, the retraction mechanism includes: a support assembly disposed on the movable base 1;

[0062] The support assembly includes: two fixed frames 304 symmetrically fixedly connected to the outer wall of the movable seat 1, a dual-head motor 301 installed inside each of the two fixed frames 304, two take-up and put-down slots symmetrically opened on the side of the two fixed frames 304 that are far apart from each other, a roller 305 rotatably connected inside the fixed frame 304 in the take-up and put-down slot, and the dual-head motor 301 located between the two rollers 305.

[0063] The mounting bracket 304 is equipped with a retraction assembly;

[0064] The take-up and unwind assembly includes: two transmission rods 306 symmetrically rotatably connected inside the fixed frame 304, the two transmission rods 306 being fixedly connected to the two output ends of the dual-head motor 301 respectively; two take-up reels 302 symmetrically rotatably connected inside the fixed frame 304, the two take-up reels 302 being located on one side of the two take-up and unwind slots respectively; the two transmission rods 306 being located between the two take-up reels 302; the two take-up reels 302 being fixedly connected to the two transmission rods 306 respectively; and connecting ropes 303 being wound around the outer walls of the two take-up reels 302. The connecting ropes 303 pass through the take-up and unwind slots and are fixedly connected to the first movable frame 4. The connecting ropes 303 are in contact with the outer wall of the roller 305. Through the cooperation of the support assembly and the take-up and unwind assembly, the tube can be in an inclined state before electrolysis, effectively avoiding the situation where the electrolyte cannot contact the inner wall of the tube due to air bubbles, etc.

[0065] The above embodiments disclose a hoisting structure and an EP tube electrolysis production device containing the structure. In use, multiple tubes are placed on the upper surface of the placement platform 13, and then two dual-head motors 301 are started synchronously. At this time, the winding reel 302, driven by the dual-head motors 301 through the transmission rod 306, drives the first moving frame 4 to descend stably through the connecting rope 303. At the same time, the roller 305 rotates under the drive of the connecting rope 303. Simultaneously, the positioning hooks 203 descend synchronously under the drive of the first moving frame 4 through the connecting slide plate 207 and the second moving frame 6, until the multiple positioning hooks 203 move to the ends of the multiple tubes respectively.

[0066] Then, the dual-head motor 301 is stopped, and the first servo motor 2015 is started to drive the bevel gear 2014 to rotate. At this time, the bevel ring 2010 drives the bidirectional lead screw 205 to rotate under the meshing drive of the bevel gear 2014. At the same time, the moving sleeve 208, driven by the thread of the bidirectional lead screw 205, drives the positioning hook 203 to be inserted into the inside of the pipe through the connecting slide plate 207. At this time, the moving slider 206, driven by the connecting slide plate 207, drives the roller to move along the inner wall of the second moving frame 6. At the same time, the rack 209, driven by the connecting slide plate 207, slides along the inner wall of the second moving frame 6, and the limiting slider 202, driven by the rack 209, slides along the inner wall of the first moving frame 4, so that multiple pipes can be conveniently clamped.

[0067] Then, the dual-head motor 301 is started to drive the first moving frame 4 to rise. At this time, multiple pipes are separated from the upper surface of the placement platform 13 under the drive of the positioning hook 203. Then, the second servo motor 7 is started to drive the transmission screw 9 to rotate. At this time, the moving seat 1 slides along the outer wall of the transmission screw 9 under the drive of the thread of the transmission screw 9, so that the pipes can be transported to the top of the electrolytic cell 11 for convenient hoisting of multiple pipes.

[0068] At this time, the hydraulic push rod 2017 is activated to push the second moving frame 6 to separate from the first moving frame 4. Simultaneously, the connecting slider 201, driven by the second moving frame 6, slides along the outer wall of the lifting slide rod 2018. During this process, the adjusting rod 2013, driven by the connecting slide plate 207, drives the spur gear 204 to descend steadily. At this time, the limiting slider 202, restricted by the inner wall of the first moving frame 4, keeps the rack 209 stationary. This allows the spur gear 204 to rotate the adjusting rod 2013 during descent by meshing with the outer wall of the rack 209. 013 The guide slide groove squeezes the outer wall of the guide slider 2016, so that the guide slider 2016 can drive the sliding sleeve 2012 to slide along the outer wall of the first limit rod 2011 under the squeezing and guidance of the inner wall of the guide slide groove. At this time, the positioning hook 203 drives the tube to move synchronously under the drive of the sliding sleeve 2012 until the lifting slide rod 2018 is connected to the top of the inner wall of the connecting slider 201. This allows for convenient adjustment of the spacing between multiple tubes, effectively avoiding damage, scars and uneven smoothness on the surface of the tubes due to contact between the outer walls during the electrolysis process.

[0069] Simultaneously, a dual-head motor 301 is started, driving two take-up reels 302 to rotate synchronously via two transmission rods 306. This allows the first moving frame 4 to descend one side through unwinding. At this time, the second moving frame 6, driven by the connecting slider 201, lowers one end of the tube, thus tilting the entire tube. Then, the two dual-head motors 301 are started, allowing multiple tubes to enter the inner cavity of the electrolysis tank 11 in an tilted state. Since multiple tubes are tilted, the electrolyte can fully contact the inner wall of the tube, effectively preventing the electrolyte from failing to contact the inner wall of the tube due to air bubbles. When the electrolysis operation of the tube is completed, the tube is placed in the inner cavity of the cleaning tank 12 through unwinding and rewinding to remove residual electrolyte from the surface of the tube and prevent the residual electrolyte from corroding the tube.

[0070] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
