Description

Technical Field

[0001] The present invention relates to the technical field of anchor chain processing, and particularly to a surface anti-corrosion coating device for anchor chain production. Background Art

[0002] An anchor chain refers to a special chain that connects an anchor and a hull and transmits the anchor holding force. The anchor chain is an important component related to the mooring safety of various ships and offshore equipment. Its service conditions are harsh, mostly in corrosive environments such as high temperature, high humidity, chemicals, air pollution, and high-salt salt spray in the ocean. If the surface of the anchor chain is not covered with anti-corrosion materials, its service life will be greatly shortened. Coating the surface of the anchor chain with a corrosion-resistant paint film can greatly slow down the degree of corrosion and extend its service life.

[0003] In the prior art, when most anchor chain processing workshops coat the anchor chain with paint film, they use a lifting device to lift the anchor chain and send the anchor chain into an immersion tank filled with paint material by the lifting device. Since the overlapping area between each ring of the anchor chain in a straightened state is the smallest, the anchor chain is always in a vertical state during the process of sinking to the bottom of the tank, thereby increasing the film-forming area.

[0004] However, in the actual production process, even though the anchor chain is always in a vertical state, there is still a very small overlapping area at the connection of each ring of the anchor chain. During the paint dipping process, the paint material cannot fully dip the overlapping part of the anchor chain, resulting in insufficient paint dipping of the anchor chain, and the overlapping part is easily corroded by seawater. Summary of the Invention

[0005] The purpose of the present invention is to solve the drawback that it is difficult to coat the overlapping part of the anchor chain in the prior art, and to provide a surface anti-corrosion coating device for anchor chain production.

[0007] Preferably, a sprocket tile is fixedly connected to the bottom of the baffle, the sprocket tile covers the bottoms of both the feeding sprocket and the discharging sprocket, and a sponge pad is provided in the sprocket tile to elastically support the anchor chain on the feeding sprocket and the discharging sprocket.

[0008] Preferably, a base is fixedly connected to the bottom of the cylinder block. A driving structure is provided on the base to drive the baffle to lift.

[0010] Preferably, a spline shaft is rotatably installed in the middle of the base. A driven gear is fixedly connected to the bottom end of the spline shaft. The driven gear is matched with the incomplete gear. The top end of the spline shaft is slidably fitted inside the internal spline tube.

[0011] Preferably, a circular ring member is fixedly connected to the outer wall of the box body. An opening is formed on the inner wall of the ring member.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Refer to Figure 1 And Figure 2 As shown, a surface anti-corrosion coating device for anchor chain production includes a box body 1 for accommodating liquid paint. A fixed shaft 4 is fixedly connected to the inner top of the box body 1. A feed guiding sprocket 5 and a discharge guiding sprocket 6 are rotatably installed on the fixed shaft 4. A rotating shaft 7 is rotatably installed on one side of the box body 1. A reversing sprocket 8 is fixedly connected to the shaft body of the rotating shaft 7. A cylinder block 2 is fixedly connected to the bottom of the box body 1. A baffle plate 15 is slidably fitted in the cylinder block 2. A support 16 is fixedly connected to the upper surface of the baffle plate 15. A support shaft 17 is fixedly connected to the support 16. A feed sprocket 18 and a discharge sprocket 19 are rotatably installed on the shaft body of the support shaft 17.

[0032] When the device performs the coating work on the anchor chain, the worker sequentially introduces the head of a section of the anchor chain into the box body 1 through the feed guiding sprocket 5, the feed sprocket 18 and the reversing sprocket 8, and then leads it out of the box body 1 through the discharge sprocket 19 and the discharge guiding sprocket 6, so as to complete the loading and unloading work of the anchor chain in the box body 1.

[0033] As Figures 7 - 12 Shown, a sprocket tile 22 is fixedly connected to the bottom of the baffle plate 15. The sprocket tile 22 covers the bottoms of both the feed sprocket 18 and the discharge sprocket 19. A sponge pad 27 is provided in the sprocket tile 22 to elastically support the anchor chain on the feed sprocket 18 and the discharge sprocket 19.

[0034] In the working process of the anchor chain entering and exiting the box body 1 as described above, every time a link of the anchor chain enters and exits the box body 1, the baffle 15 completes a reciprocating motion in the vertical direction. During the upward movement of the baffle 15, the sprocket tile 22 on the bottom surface of the baffle 15 will lift the lowermost anchor chain upward. The upper anchor chain is in a vertical state under the action of gravity. During the upward movement of the lowermost anchor chain, the anchor chain in contact with the sponge pad 27 will separate from the upper anchor chain, so that the overlapping part of the rings is separated, allowing the paint to enter and paint the overlapping part.

[0035] As Figures 9 - 13 shown, a base 3 is fixedly connected to the bottom of the cylinder block 2. A driving structure is provided on the base 3 to drive the baffle 15 to move up and down. The driving structure includes a main shaft 32. The main shaft 32 is rotatably installed on the base 3. The top end of the main shaft 32 extends into the cylinder block 2 and is fixedly connected with an incomplete gear 31. An annular gear 30 that cooperates with the incomplete gear 31 is rotatably installed in the cylinder block 2. A plurality of wedge-shaped first stoppers 29 are fixedly connected to the outer wall of the annular gear 30. A plurality of second stoppers 28 are fixedly connected to the bottom surface of the baffle 15. The inclined surface of the first stopper 29 abuts against the second stopper 28.

[0036] The main shaft 32 serves as the power input end to drive the incomplete gear 31 to rotate. During the rotation of the incomplete gear 31, it will intermittently drive the annular gear 30 to rotate. The rotation of the annular gear 30 will drive the first stopper 29 on its outer wall to revolve in the cylinder block 2. During the rotation of the first stopper 29, it will exert an upward supporting force on the second stopper 28. The second stopper 28 will move up and down under the action of the supporting force and gravity, thereby driving the baffle 15 to perform a linear reciprocating motion in the vertical direction.

[0037] As Figures 11 - 13 shown, a spline tube 23 is rotatably installed in the middle of the sprocket tile 22. A transmission gear 24 is fixedly connected to the top end of the spline tube 23. A first end face gear 20 is fixedly connected to the end face of the feed sprocket 18. A second end face gear 21 is fixedly connected to the end face of the discharge sprocket 19. Both the first end face gear 20 and the second end face gear 21 are matched with the transmission gear 24. A spline shaft 25 is rotatably installed in the middle of the base 3. A driven gear 26 is fixedly connected to the bottom end of the spline shaft 25. The driven gear 26 is matched with the incomplete gear 31. The top end of the spline shaft 25 is slidably fitted inside the spline tube 23.

[0038] During the rotation of the incomplete gear 31, it will intermittently engage with the driven gear 26. When the two are engaged, the incomplete gear 31 will drive the driven gear 26 to rotate. The rotation of the driven gear 26 drives the spline tube 23 to rotate through the spline shaft 25. The rotation of the spline tube 23 drives the transmission gear 24 to rotate. The rotation of the transmission gear 24 drives the first end face gear 20 and the second end face gear 21 to rotate in opposite directions, so that the feed sprocket 18 and the discharge sprocket 19 both rotate and rotate in opposite directions.

[0039] As shown Figures 3 - 6 in FIG. 1, a circular ring-shaped member 9 is fixedly connected to the outer wall of the box body 1. An opening 14 is formed in the inner wall of the ring member 9. A round head pin 11 is slidably fitted in the opening 14. A compression spring 10 is provided in the opening 14 to apply an elastic force to the round head pin 11. The end of the rotating shaft 7 penetrates through the box wall of the box body 1 and passes through the ring member 9. A turntable 12 is fixedly connected to the end of the rotating shaft 7. A plurality of arc-shaped limiting grooves 13 are formed in the outer ring of the turntable 12. The round head pin 11 abuts against the limiting groove 13.

[0040] The round head pin 11 abuts against the limiting groove 13 under the elastic force of the compression spring 10, thereby limiting the turntable 12 to a certain extent, preventing the reversing sprocket 8 from rotating accidentally, and further preventing the anchor chain from driving the reversing sprocket 8 to rotate under its own gravity.

[0041] Working principle: Taking the rotation of the incomplete gear 31 driven by the main shaft 32 for one week as an example: In the initial state, the incomplete gear 31 meshes with the driven gear 26 to drive the driven gear 26 to rotate.

[0042] During the rotation of the driven gear 26, through the cooperation of the spline shaft 25 and the internal spline tube 23, the transmission gear 24 is driven to rotate. The rotation of the transmission gear 24 drives the first end face gear 20 and the second end face gear 21 to rotate in opposite directions, so that the feeding sprocket 18 and the discharging sprocket 19 rotate and rotate in opposite directions.

[0043] The rotation of the feeding sprocket 18 drives the anchor chain to feed into the box body 1, and the rotation of the discharging sprocket 19 drives the anchor chain to discharge from the box body 1. The feeding and discharging processes are carried out simultaneously.

[0044] After the anchor chain is displaced by one ring, the incomplete gear 31 is separated from the driven gear 26. At this time, the feeding sprocket 18 and the discharging sprocket 19 will stop moving and temporarily stop the feeding and discharging work of the anchor chain.

[0045] After the incomplete gear 31 is separated from the driven gear 26, the annular gear 30 starts to contact the incomplete gear 31. At this time, the incomplete gear 31 drives the annular gear 30 to rotate.

[0046] The rotation of the annular gear 30 drives the first stopper 29 on its outer wall to revolve in the cylinder block 2. During the rotation of the first stopper 29, an upward supporting force is applied to the second stopper 28. Under the action of the supporting force and gravity, the second stopper 28 will move up and down once, thereby driving the baffle 15 to perform a reciprocating motion in the vertical direction.

[0047] As Figure 14As shown, during the reciprocating motion of the baffle 15, when the baffle 15 is ascending, the sponge pad 27 within the sprocket tile 22 on the bottom surface of the baffle 15 will lift the anchor chain in the dotted line part upward. The anchor chain in the solid line part is in a vertical state under the action of gravity. When the anchor chain in the dotted line part moves upward, the anchor chain in the solid line part will not move. Therefore, the overlapping part between the two will open, enabling the paint to enter the overlapping area for painting work.

[0048] In addition, during the ascending stage of the baffle 15, the upward movement of the baffle 15 within the cylinder block 2 will cause a short-term decrease in the pressure inside the cylinder block 2. Part of the anchor chain located below the baffle 15 is also within the cylinder block 2, and the air bubbles on the surface of the anchor chain will be extracted at the same time when the pressure inside the cylinder block 2 decreases, so as to prevent air bubbles from existing in the paint film.

[0049] After the ascending stage of the baffle 15 ends, due to the wedge-shaped structural design of the first stop block 29 and the second stop block 28, the supporting force given by the first stop block 29 to the second stop block 28 will suddenly disappear. The second stop block 28 will move downward together with the baffle 15 and the sprocket tile 22 under the action of gravity. The anchor chain in the dotted line part will also fall downward under the action of gravity. When the anchor chain in the dotted line part moves down to the lowest point, it will exert a large instantaneous impact force on the anchor chain in the solid line part, causing the anchor chain to vibrate, thereby shaking out the air bubbles in the paint film of the anchor chain and improving the painting quality.

[0050] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
