Description

Technical Field

[0001] This invention relates to the field of anchor chain impregnation, and more specifically, to an apparatus and method for surface anti-corrosion impregnation of anchor chains. Background Technology

[0002] Anchor chains are steel chains that connect a ship's hull to its anchor. Their main functions are: connecting the anchor to the ship and transmitting the anchor's holding force to the hull; when anchored, the weight of the deployed chain helps buffer against external forces such as wind and current in the water; the portion of the chain lying flat on the seabed keeps the anchor's force horizontal, facilitating reliable bottom holding. This portion of the chain also provides some anchoring force due to the resistance of the mud; because anchor chains are exposed to humid environments, they are prone to corrosion. Impregnation with paint forms a protective film on the surface, preventing chemical reactions between the iron and other substances, thus achieving rust prevention. Therefore, anchor chains require impregnation during use.

[0003] Currently, most existing paint impregnation methods involve placing the anchor chain directly inside a box-type device filled with paint liquid. This causes the various links of the anchor chain to be squeezed and piled up, making it impossible to effectively impregnate the contact points. In addition, the piled-up anchor chains also occupy a lot of usable space, and subsequent recycling and other processing are not easy.

[0004] To address the aforementioned issues, this application proposes a surface anti-corrosion impregnation device and method for anchor chain processing. Summary of the Invention

[0005] The purpose of this invention is to provide a surface anti-corrosion impregnation device and method for anchor chain processing, so as to solve the problems in the prior art.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A surface anti-corrosion coating device for anchor chain processing includes a coating tank. The interior of the coating tank is divided into sections with coating trays. The upper end of each coating tray has a tapered, inclined structure that allows the anchor chain to automatically spread outwards and coil. A limiting shaft is installed inside the coating tank, and a spiral blade is installed on the outer side of the limiting shaft. A top seat is installed at the upper end of the coating tank to limit the top of the limiting shaft. A protruding cam gear is installed on the outer side of the upper end of the limiting shaft. An electric gear for rotating the cam gear is installed on one side of the upper end of the coating tank. A bellows for applying air force to the anchor chain is installed on the other side of the upper end of the coating tank. A protruding convex ring seat is installed at the upper end of the coating tank, and an inner ring seat is installed inside the convex ring seat. A rotating block is installed at the lower end of the limiting shaft, and a locking block is installed at the bottom of the rotating block. A limiting groove is opened at the upper end of the coating tray for rotating and mounting the rotating block, and a locking groove is opened at the lower end of the limiting groove for engaging the locking block.

[0008] Furthermore, the outer side of the dipping tray is provided with a connecting rod for connecting multiple dipping trays together, and the outer side of the limiting shaft near the upper end is provided with a protruding boss.

[0009] Furthermore, a rotating sleeve is fitted on one side of the boss, and a pull rod for limiting the upper end of the anchor chain is provided at the lower end of the rotating sleeve.

[0010] Furthermore, a limiting ring for limiting the sliding space of the anchor chain is provided on the inner side of the inner ring seat, and a heating platform is provided on the inner side of the inner ring seat, and a heating wire is provided on the inner side of the heating platform.

[0011] Furthermore, one end of the bellows is provided with a guide pipe for transmitting air force, and the lower end of the inner ring seat is provided with an air guide cavity that communicates with the guide pipe.

[0012] Furthermore, the lower end of the air guide cavity is provided with guide vanes for directing airflow downwards at an angle, and the lower end of the air guide cavity is also provided with support rods for limiting the position of multiple guide vanes.

[0013] Furthermore, an electric telescopic rod for driving the top seat to move up and down is provided on one side of the upper end of the paint impregnation tank, and a protrusion for rotatably connecting with the top seat is provided on the upper end of the limiting shaft.

[0014] Furthermore, a method for surface anti-corrosion impregnation coating for anchor chain processing,

[0015] S1: When it is necessary to impregnate, the anchor chain can be lowered to the top of the spiral plate to make it spiral down, and then spread outward when it reaches the lowest point. The cone-shaped structure of the impregnation tray can make the anchor chain move automatically downward while spreading outward.

[0016] S2: Drive the electric telescopic rod to move the top seat down, which can press down the cam gear to make it mesh with the electric gear;

[0017] S3: The drive electric gear can drive the limit shaft to rotate, thereby causing the anchor chain to spiral down while its outward part rotates and unfolds at the top of the paint-dipping tray to form a coil.

[0018] S4: Drive the electric telescopic rod to move the limit shaft down, causing the locking block to engage inside the slot. At this time, drive the electric gear to rotate the paint dipping disc so that the anchor chain is in full contact with the paint.

[0019] Furthermore, S5: At the end of the impregnation, the drive box transmits the air force to the inside of the inner ring seat through the guide pipe, and then the air is blown downwards by the guide vanes toward the rising anchor chain;

[0020] S6: As the anchor chain continues to rise, heating wires are used to dry the air-dried portion of the anchor chain, causing the paint to solidify on the surface of the anchor chain, so that it can be directly collected and stored after removal.

[0021] Furthermore, S7: When the anchor chain is lowered to the end, the rotating sleeve is fitted inside the boss to form a rotating connection using an external clamping device. At this time, one end of the anchor chain is lifted by the hook at the lower end of the pull rod to form a suspension.

[0022] S8: When it is necessary to remove the anchor chain, simply pull the rotating sleeve outward using the external clamping device.

[0023] The beneficial effects of this invention are:

[0024] 1. This invention, by segmenting the interior of the paint-dipping tank with paint-dipping trays, allows the anchor chains to be guided downwards by spiral plates and automatically spread outwards to coil around the upper surface of the paint-dipping trays when placed, thus filling the storage space of each tray. At this time, the electric telescopic rod drives the cam gear to move downwards and mesh with the electric gear, and drives the locking block to engage inside the limiting groove, thus starting the rotation. This increases the contact area between the anchor chain and the paint, allowing the paint to penetrate into the joint gaps of each link. The operation is simple and avoids the accumulation of anchor chains occupying too much space. It is convenient for placement and removal, and can also rotate during the paint-dipping process to improve the contact area and paint-dipping efficiency, ensuring the quality of the paint after removal.

[0025] 2. This invention, by setting a wind box on one side of the upper end of the paint dipping tank, can transmit air power to the interior of the air guide cavity through the guide pipe. Then, after being guided by the guide vanes, the residual paint on the surface of the anchor chain is blown off at an angle downwards. This avoids the paint dripping outwards when the anchor chain is taken out directly, and allows it to fall directly into the interior of the paint dipping tank for recycling. Furthermore, as the anchor chain continues to move upwards, a heating wire can be used to dry it, so that the anchor chain is kept dry immediately after being taken out, making it easy to collect and use, thus improving its practical performance.

[0026] 3. This invention provides a boss on the outer side of the limiting shaft near the upper end, allowing the rotating sleeve to be directly fitted onto one side of the boss and the upper end of the anchor chain to be fixed by a pull rod. Thus, the anchor chain can be directly removed by the pull rod at the end of the impregnation process. The structure is simple and easy to operate. Attached Figure Description

[0045] Please continue reading. Figure 7 A method for surface anti-corrosion impregnation coating for anchor chain processing.

[0046] S1: When it is necessary to impregnate, the anchor chain can be spiraled down from the bottom to the top of the spiral plate 4, and then spread outward when it reaches the lowest point. The cone-shaped structure of the impregnation plate 2 can make the anchor chain move automatically downward while spreading outward.

[0047] S2: Drive the electric telescopic rod 26 to move the top seat 5 downward, which can press down the cam gear 6 to make it mesh with the electric gear 7;

[0048] S3: The drive electric gear 7 can drive the limit shaft 3 to rotate, thereby causing the anchor chain to rotate and unfold at the upper end of the immersion tray 2 while descending in a spiral motion to form a coil.

[0049] S4: Drive the electric telescopic rod 26 to move the limit shaft 3 down, causing the locking block 12 to engage inside the slot 14. At this time, drive the electric gear 7 to rotate the paint dipping tray 2 so that the anchor chain can fully contact the paint.

[0050] S5: At the end of the impregnation, the drive bellows 8 transmits the wind force to the inside of the inner ring seat 10 through the guide pipe 22, and then the wind is diverted downward through the guide vane 24 and blown towards the rising anchor chain.

[0051] S6: As the anchor chain continues to rise, the heating wire 21 is used to dry the air-dried part of the anchor chain, so that the paint solidifies on the surface of the anchor chain, allowing it to be collected and stored directly after removal.

[0052] S7: When the anchor chain is lowered to the end, the rotating sleeve 17 is fitted into the inside of the boss 16 using an external clamping device to form a rotating connection. At this time, one end of the anchor chain is lifted by the hook at the lower end of the pull rod 18 to form a suspension.

[0053] S8: When it is necessary to remove the anchor chain, simply pull the rotating sleeve 17 outward using the external clamping device.

[0054] It is understandable that the present invention utilizes segmented paint-impregnation trays 2 to reduce the space occupied by the anchor chain while avoiding the situation where a large number of links are squeezed against each other, resulting in insufficient paint impregnation on the contact surface. Furthermore, the anchor chain can be air-dried and oven-dried in real time during the removal process, so that it can be directly stored and put into use after removal.

[0055] The working principle of this invention is as follows:

[0056] This invention, by segmenting the interior of the paint-impregnation tank 1 with paint-impregnation trays 2, allows the anchor chain to be placed. The spiral plate 4 on the outer side of the tray 2 guides the chain downwards, and the conical structure at the upper end of the tray 2 allows the anchor chain to automatically spread outwards, eventually coiling around the upper surface of the tray 2, filling the storage space of each tray. At this point, an electric telescopic rod 26 located on one side of the upper end of the paint-impregnation tank 1 drives the convex gear 6 on the outer side of the upper end of the limiting shaft 3 to move downwards and mesh with the electric gear 7. This causes the locking block 12 located at the lower end of the rotating block 11 at the bottom of the limiting shaft 3 to engage with the locking groove 14 on the inner side of the paint-impregnation tray 2, thus initiating rotation. This increases the contact area between the anchor chain and the paint, allowing the paint to penetrate into the joints of each link. The operation is simple, avoiding excessive space occupied by piled-up anchor chains, facilitating placement and removal. Furthermore, rotation during the impregnation process increases the contact area and impregnation efficiency, ensuring the quality of the impregnated chain after removal. This invention, through the paint-impregnation tank 1... After the wind box 8 is installed on the upper side, the wind can be transmitted to the air guide cavity 23 at the lower end of the inner ring seat 10 through the guide pipe 22 at its end. Then, the guide vane 24 inside the lower opening of the air guide cavity 23 guides the residual paint on the surface of the anchor chain obliquely downward, avoiding direct dripping when taken out, and allowing it to fall directly into the paint dipping tank 1 for recycling. Furthermore, as the anchor chain continues to move upward, the heating wire 21 set inside the heating platform 20 near the upper end of the inner ring seat 10 can be used for drying, so that the anchor chain is kept dry immediately after being taken out, which is convenient for collection and other processing, improving its practical performance. After the limiting shaft 3 inside the paint dipping tank 1 is set with a boss 16 near the upper end, the rotating sleeve 17 can be directly sleeved on one side of the boss 16, and the upper end of the anchor chain is fixed by the pull rod 18 set at the bottom of the rotating sleeve 17. Then, the anchor chain can be directly taken out by the pull rod 18 when the paint dipping is finished. The structure is simple and easy to operate.
