Description

Technical Field

[0001] The present invention relates to the technical field of anchor chain processing, in particular to surface anti-corrosion coating equipment for anchor chain production. Background Art

[0002] Anchor chain refers to a special chain that connects the anchor and the hull and transmits the anchor's grip. Anchor chain is a key component related to the mooring safety of various ships and marine engineering equipment. Its service conditions are harsh, mostly in the corrosive environment of high temperature, high humidity, chemicals, air pollution and high salt mist in the ocean. If the surface of the anchor chain is not covered with anti-corrosion material, its service life will inevitably be greatly shortened. Coating the surface of the anchor chain with a corrosion-resistant paint film can greatly reduce the degree of corrosion and extend its service life.

[0003] In the prior art, most anchor chain processing workshops use lifting equipment to lift the anchor chain when coating the anchor chain with paint, and then use the lifting equipment to put the anchor chain into a soaking tank filled with paint. Since the overlapping area between each link of the anchor chain in the straight 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 if the anchor chain is always in a vertical state, there is still a very small overlapping area where each link of the anchor chain is connected to each other. During the painting process, the paint cannot fully penetrate the overlapping parts of the anchor chain, resulting in insufficient painting of the anchor chain and the overlapping parts are easily corroded by seawater. Summary of the Invention

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1 and Figure 2 As shown, a surface anti-corrosion coating equipment for anchor chain production includes a box body 1 for containing liquid paint, a fixed shaft 4 is fixedly connected to the top of the box body 1, and a feed guide sprocket 5 and a discharge guide sprocket 6 are rotatably mounted on the fixed shaft 4, a rotating shaft 7 is rotatably mounted on one side of the box body 1, and a reversing sprocket 8 is fixedly connected to the shaft body of the rotating shaft 7, a cylinder body 2 is fixedly connected to the bottom of the box body 1, a baffle 15 is slidably fitted in the cylinder body 2, a support 16 is fixedly connected to the upper surface of the baffle 15, a support shaft 17 is fixedly connected to the support 16, and a feed sprocket 18 and a discharge sprocket 19 are rotatably mounted on the shaft body of the support shaft 17.

[0033] When the device is coating the anchor chain, the worker introduces the head of a section of the anchor chain into the box body 1 through the feed guide sprocket 5, the feed sprocket 18 and the reversing sprocket 8 in sequence, and then leads it out of the box body 1 through the discharge sprocket 19 and the discharge guide sprocket 6, so that the anchor chain completes the loading and unloading work in the box body 1.

[0034] like Figure 7-12 As shown, a sprocket shoe 22 is fixed to the bottom of the baffle 15, and the sprocket shoe 22 covers the bottom of the feed sprocket 18 and the discharge sprocket 19. A sponge pad 27 is provided in the sprocket shoe 22 to elastically support the anchor chains on the feed sprocket 18 and the discharge sprocket 19.

[0035] During the working process of the above-mentioned anchor chain entering and exiting the box body 1, 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 rising process of the baffle 15, the sprocket shoe 22 on the bottom surface of the baffle 15 will lift the anchor chain at the bottom end to move upward, while the upper anchor chain is in a vertical state under the action of gravity. During the upward movement of the lowest anchor chain, the anchor chain in contact with the sponge pad 27 will separate from the upper anchor chain, thereby separating the overlapping parts of the links to allow paint to enter and paint the overlapping parts.

[0036] like Figures 9-13 As shown, the bottom of the cylinder body 2 is fixedly connected to a base 3, and a driving structure is provided on the base 3 to drive the baffle 15 to rise and fall. The driving structure includes a main shaft 32, which is rotatably mounted on the base 3. The top of the main shaft 32 extends into the cylinder body 2 and is fixedly connected to an incomplete gear 31. A ring gear 30 that cooperates with the incomplete gear 31 is rotatably installed in the cylinder body 2. A plurality of wedge-shaped first stops 29 are fixed to the outer wall of the ring gear 30, and a plurality of second stops 28 are fixed to the bottom surface of the baffle 15. The inclined surface of the first stop 29 rests on the second stop 28.

[0037] The main shaft 32 serves as the power input end to drive the incomplete gear 31 to rotate. During the rotation process, the incomplete gear 31 will intermittently drive the ring gear 30 to rotate. The rotation of the ring gear 30 will drive the first stopper 29 on its outer wall to revolve in the cylinder body 2. During the rotation of the first stopper 29, an upward supporting force will be applied to 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 linear reciprocating motion in the vertical direction.

[0038] like Figure 11-13 As shown, an inner spline tube 23 is rotatably mounted in the middle of the sprocket bushing 22, a transmission gear 24 is fixedly connected to the top end of the inner spline tube 23, a first end face gear 20 is fixedly connected to the end face of the feed sprocket 18, and 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 mounted in the middle of the base 3, a driven gear 26 is fixedly connected to the bottom end of the spline shaft 25, and the driven gear 26 is matched with the incomplete gear 31, and the top end of the spline shaft 25 is slidably fitted in the inner spline tube 23.

[0039] 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 inner spline tube 23 to rotate through the spline shaft 25. The rotation of the inner 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 the opposite direction, so that the feed sprocket 18 and the discharge sprocket 19 both rotate and the rotation directions are opposite.

[0040] like Figure 3-Figure 6 As shown, a circular ring 9 is fixed to the outer wall of the box body 1, an opening 14 is provided on the inner wall of the ring 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 elastic force to the round head pin 11, the end of the rotating shaft 7 passes through the box wall of the box body 1 and passes through the ring 9, a turntable 12 is fixed to the end of the rotating shaft 7, a plurality of arc-shaped limit grooves 13 are provided on the outer ring of the turntable 12, and the round head pin 11 rests in the limit groove 13.

[0041] The round pin 11 rests against the limiting groove 13 under the elastic force of the compression spring 10, thereby limiting the turntable 12 to a certain extent, thereby 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.

[0042] Working principle:

[0043] Take the example of the main shaft 32 driving the incomplete gear 31 to rotate one circle:

[0044] In an initial state, the partial gear 31 meshes with the driven gear 26 to drive the driven gear 26 to rotate.

[0045] During the rotation of the driven gear 26, the transmission gear 24 is driven to rotate through the cooperation between the spline shaft 25 and the inner spline tube 23. The rotation of the transmission gear 24 drives the first end face gear 20 and the second end face gear 21 to rotate in the opposite direction, so that the feed sprocket 18 and the discharge sprocket 19 both rotate and the rotation directions are opposite.

[0046] The rotation of the feed sprocket 18 drives the anchor chain to feed into the box body 1, and the rotation of the discharge sprocket 19 drives the anchor chain to discharge from the box body 1, and the feeding and discharging processes are carried out simultaneously.

[0047] After the anchor chain moves one link, the incomplete gear 31 is separated from the driven gear 26. At this time, the feed sprocket 18 and the discharge sprocket 19 will stop moving and temporarily stop the loading and unloading of the anchor chain.

[0048] After the incomplete gear 31 is separated from the driven gear 26 , the ring gear 30 begins to contact the incomplete gear 31 . At this time, the incomplete gear 31 drives the ring gear 30 to rotate.

[0049] The rotation of the ring gear 30 will drive the first stopper 29 on its outer wall to revolve in the cylinder body 2. During the rotation of the first stopper 29, an upward supporting force will be applied to 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 reciprocating motion in the vertical direction.

[0050] like Figure 14As shown, during the reciprocating motion of the baffle 15 and the rising process of the baffle 15, the sponge pad 27 in the sprocket shoe 22 on the bottom surface of the baffle 15 will lift the anchor chain in the dotted line part to move upward, while 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 of the two will open to allow paint to enter the overlapping part for painting.

[0051] In addition, during the rising stage of the baffle 15, the upward movement of the baffle 15 in the cylinder body 2 will cause the pressure inside the cylinder body 2 to drop in a short period of time, and part of the anchor chain located below the baffle 15 is simultaneously located in the cylinder body 2. At the same time as the pressure in the cylinder body 2 drops, the bubbles on the surface of the anchor chain will be extracted to prevent the presence of bubbles in the paint film.

[0052] After the rising stage of the baffle 15, due to the wedge-shaped structural design of the first stop 29 and the second stop 28, the supporting force of the first stop 29 to the second stop 28 will suddenly disappear, and the second stop 28 will move downward together with the baffle 15 and the sprocket shoe 22 under the action of gravity, and the anchor chain in the dotted part will also fall downward under the action of gravity. When the anchor chain in the dotted part moves down to the lowest point, it will exert a large instantaneous impact force on the anchor chain in the solid part, causing the anchor chain to vibrate, thereby shaking out the bubbles in the anchor chain paint film and improving the quality of painting.

[0053] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
