Description

Technical Field

[0001] The invention relates to the technical field of surface grinding and cleaning of a studless anchor chain, and in particular to an anchor chain grinding device. Background Art

[0002] The anchor chain is a steel chain that connects the hull and the anchor. The main functions of the anchor chain are: connecting the anchor and the ship, transmitting the anchor's holding force to the hull; when anchoring, the thrown anchor chain has a certain weight, which can buffer the wind and other external forces on the ship in the water; the anchor chain lying flat on the bottom of the water keeps the force on the anchor horizontal, which is conducive to the reliable bottom holding of the anchor. At the same time, this part of the anchor chain can also provide a part of the anchoring force due to the blocking effect of the soil.

[0003] During the use of anchor chain, the surface is seriously corroded because the surface is soaked in sea water or river water and wrapped in mud for a long time. Therefore, when repairing the ship, the surface of the anchor chain needs to be cleaned and rust-proofed, and all the rust and mud on the surface need to be removed to expose the metal body, and then paint is applied for anti-corrosion.

[0004] The cleaning and rust removal of the outer side of some existing anchor chains is handled by cleaning equipment, and the cleaning and rust removal of the inner side of the anchor chain is usually done manually. Taking the non-stall anchor chain as an example, the anchor chain with a chain diameter of 50mm has a theoretical weight of 50Kg / m. Depending on the size of the ship, the length of the anchor chain is about 6 knots on average. It can be seen that the length of the anchor chain has exceeded 100m, and the difficulty and workload of manually cleaning and rust removal of the inner side of the anchor chain are very huge. Summary of the invention

[0007] Furthermore, the first storage platform includes a platform and an inclined groove arranged on the platform; A deceleration member is provided on the inner surface of the inclined groove and the limiting member. The friction coefficient of the deceleration member is above 0.3, and the deceleration member can decelerate the contact friction of the anchor chain.

[0008] Furthermore, the material of the speed reducer is one of rubber, polyurethane and ceramic.

[0012] Furthermore, it also includes a plurality of spraying members, which are arranged on the limiting ring and can spray liquid or granular solids to act on the inner side of the chain ring.

[0013] Furthermore, the ejection member includes at least one right-angle block, each of the right-angle blocks is close to the midpoint of the through hole, each of the right-angle blocks is provided with two ejection holes, and the opening directions of the two ejection holes are perpendicular to each other.

[0014] Furthermore, the cleaning assembly includes a circular tube, the tube wall of which is recessed outward to form a containing box, and there is at least one containing box for containing the cleaning member; the cleaning member includes a grinding brush, one end of which is hinged on the inner wall of the containing box, and the other end of the grinding brush can automatically approach the axis of the circular tube and extend into the inner side of the chain ring for grinding.

[0015] Further, the grinding brush comprises a grinding rod, one end of which is hinged on the inner wall of the containing box, the other end of which is connected to a flexible grinding head, the side wall of which is connected to the bottom wall of the containing box via a spring, and a protruding rod is provided on the side wall of the grinding rod facing away from the spring; A recovery box and an air compressor are arranged on the bottom side of the circular tube.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] refer to Figure 1 to Figure 7 The present invention protects an anchor chain polishing device, which includes a first storage platform 1, a cleaning component 3 and a second storage platform 4. The height of the first storage platform 1 in the vertical direction is higher than the height of the second storage platform 4 in the vertical direction. The cleaning component 3 is tilted, and the angle between the axis of the cleaning component 3 and the ground is 25°~50°, specifically, it can be 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, 45°, 48° and 50°. The inlet of the cleaning component 3 is close to the first storage platform 1, and the outlet of the cleaning component 3 is close to the second storage platform 4. The inlet end of the cleaning component 3 is connected to the first storage platform 1 as needed, and the outlet end of the cleaning component 3 is connected to the second storage platform 4. In this way, the unprocessed anchor chain 2, the processing anchor chain 2 and the processed anchor chain 2 can be separated, so that the anchor chain 2 can move in an orderly manner, and the inclined cleaning component 3 can make the anchor chain 2 move more smoothly.

[0023] The anchor chain 2 to be cleaned and derusted is put in from the entrance of the cleaning component 3 and discharged from the exit of the cleaning component 3. The anchor chain 2 is connected to the tensioning device so that the anchor chain 2 can move. The anchor chain 2 to be cleaned and derusted refers to the anchor chain 2 with dirt on the surface. The dirt can be mud, sand, oil and other substances with low adhesion; it can also be rust-like substances with high adhesion; it can also be a combination of the two. In short, the anchor chain 2 to be cleaned and derusted needs to be cleaned. The tensioning device is a conventional device that can provide tension, for example, it can be a winch, a traction machine, an electric hoist, etc. The tensioning device can pull the anchor chain 2 to move, so that the anchor chain 2 passes through the cleaning component 3, and the anchor chain 2 is cleaned and derusted.

[0024] A plurality of limiters and at least one cleaning member are provided in the cleaning assembly 3. The number of cleaning members can be 1, 2, 3, 4, 5 or 6, etc., and can be set accordingly according to the actual situation. The cleaning member is a device with a self-rotating grinding function, which can be a rigid grinding head, such as a tungsten steel grinding head, a diamond grinding head, etc. It can also be a flexible grinding head, such as a stainless steel wire grinding head. The cleaning member realizes the functions of cleaning and rust removal by grinding.

[0025] The limiter can limit the passing angle of the anchor chain 2, so that the anchor chain 2 passes through the limiter in a specific posture. Posture refers to the shape and deflection angle. It should be noted that there are multiple limiters, and passing through the limiter in a specific posture in the present application means that the anchor chain 2 has the same posture when passing through one of the limiters. For example, there are a first limiter and a second limiter, and the posture of each link in the anchor chain 2 after passing through the first limiter is the same, and the posture of each link in the anchor chain 2 after passing through the second limiter is also the same, but the posture of the link after passing through the first limiter may be the same as or different from the posture of the link after passing through the second limiter.

[0026] A plurality of chain rings are provided on the anchor chain 2, and the cleaning member can extend into the inner side of the chain ring for grinding, cleaning and rust removal. The inner side of the chain ring is the side wall of the inner circle of the chain ring.

[0027] The present invention can place the anchor chain 2 on the first placement platform 1 by providing the first placement platform 1 and the second placement platform 4. The first placement platform 1 is used to bear the main weight of the uncleaned anchor chain 2, and the second placement platform 4 is used to bear the cleaned anchor chain 2. During the cleaning operation, only the section that needs to be cleaned and derusted is placed in the cleaning component 3 for processing, which is convenient for controlling the moving speed of the anchor chain 2 in the cleaning component 3 and preventing the main weight of the anchor chain 2 from pressing on the cleaning component 3 and damaging the cleaning component 3.

[0028] The present invention provides a cleaning member with a grinding function, which can grind, clean and remove rust from the anchor chain 2. The present invention provides a limiting member, which can limit the passing angle of the anchor chain 2 in the cleaning and rust removal section, so that the anchor chain 2 passes through the limiting member in the same posture. Figure 5 For example, the anchor chain 2 has a horizontal ring 21 and a vertical ring 22. When the vertical ring 22 passes through the stopper, the ring hole of the horizontal ring 21 faces the cleaning member, so that the cleaning member can extend into the inner side of the horizontal ring 21 for grinding and cleaning, which is convenient for the cleaning member to extend into the inner side of the chain ring for grinding, cleaning and rust removal. Providing multiple stoppers can also keep the anchor chain 2 as straight as possible in the cleaning assembly 3, which is convenient for grinding and cleaning of the cleaning member.

[0029] The present invention sets an inclined cleaning component 3. Relative to the vertically set cleaning component 3, the anchor chain 2 entering the cleaning component 3 can move slowly under the action of gravity, so that the moving speed of the anchor chain 2 in the cleaning component 3 can be controlled by the tension device. This has two functions. The first function is to enable the cleaning member to extend into the interior of the chain link for sufficient polishing, cleaning and rust removal; the second function is to enable the anchor chain 2 to pass through the limit member more accurately to achieve the conversion of posture.

[0030] When the anchor chain grinding device is working: the tension device intermittently pulls the anchor chain 2, each time making the anchor chain 2 move a small distance, and then pauses for 5s to 15s. During the pause, the anchor chain 2 will move a small amplitude, or not move, so that there is enough time for the cleaning piece to complete the action of extending into the chain link of the anchor chain 2 and effectively grind the inner side. At the same time, the pause can also extend the grinding and cleaning of the cleaning piece on the same position, improving the grinding and cleaning effect.

[0031] refer to Figure 1~Figure 3 In a specific embodiment, the first storage platform 1 includes a platform 11 and an inclined groove 12 disposed on the platform 11. The inclined groove 12 can be directly opened on the surface of the platform 11; or the inclined groove 12 can be externally connected to one end of the platform 11.

[0032] Speed ​​reducers are provided on the inner surface of the inclined groove 12 and the limiter, and the friction coefficient of the speed reducer is above 0.3, so that the speed reducer can reduce the contact friction of the anchor chain 2. The speed reducer provided on the inner surface of the inclined groove 12 and the speed reducer provided on the limiter can be made of the same material or different materials. For example, the speed reducer provided on the inner surface of the inclined groove 12 and the speed reducer provided on the limiter can both be the first speed reducer; or the speed reducer provided on the inner surface of the inclined groove 12 can be the first speed reducer, and the speed reducer provided on the limiter can be the second speed reducer. Of course, the speed reducers on multiple limiters can also be different, and can be the first speed reducer, the second speed reducer, the third speed reducer, the fourth speed reducer, etc.

[0033] The deceleration member provided in this embodiment has two functions. Figure 3 The first function is to slow down the downward movement of the anchor chain 2. When the angle of the cleaning component 3 is large, the anchor chain 2 is more likely to slide down. There may be a situation where the tension device does not provide tension, and the anchor chain 2 itself will move downward along the cleaning component 3 at a faster speed. The deceleration member can provide friction to slow down the downward movement of the anchor chain 2, and try to make the anchor chain 2 move downward only through the tension device, so that the movement time and pause distance of the anchor chain 2 can be controlled. In this way, the cleaning member can better play a cleaning role. The second function is to make the anchor chain 2 as straight as possible. Figure 3For example, the anchor chain 2 is arranged inside the cleaning component 3, and multiple limiters can make the anchor chain 2 as straight as possible. However, the anchor chain 2 between adjacent limiters may bend downward under the action of gravity. After the deceleration member is set, under the pulling of the tension device, the anchor chain 2 can be stretched as straight as possible under the action of the reverse friction force of the deceleration member, which is convenient for the grinding and cleaning of the cleaning member. More importantly, when the tension device is paused, the limiter is provided with a deceleration member, which can have a greater friction force on the anchor chain 2, and overcome the gravity of the anchor chain 2 between the two limiters to a certain extent, so that the anchor chain 2 is stretched as straight as possible, which is convenient for the grinding and cleaning of the cleaning member.

[0034] Preferably, the material of the deceleration member is one of rubber, polyurethane and ceramic. Among them, the friction coefficient of rubber is generally between 0.3 and 0.6, and the friction between rubber and iron is 0.6, and the friction force is relatively large. The friction coefficient of polyurethane is about 0.5, and if it is under working conditions with wetting media such as water and oil, its wear resistance is often several to dozens of times that of ordinary rubber materials. The friction coefficient of ceramics is also about 0.5, and it has strong wear resistance itself. In addition, ceramics have high thermal stability. Taking ceramic brake pads as an example, even when the brake disc temperature is as high as 650°C, its friction coefficient can still be maintained at about 0.45~0.55. The deceleration member on the limiter is preferably made of ceramic material. In this way, when the limiter heats up, the deceleration member on the limiter can still maintain a certain friction.

[0035] refer to Figure 3 and Figure 5 In a specific embodiment, there is a deflection angle between adjacent stoppers, so that after the anchor chain 2 passes through the stopper, the anchor chain 2 will deflect around its own axis. In this embodiment, there is a deflection angle between adjacent stoppers, and the deflection method is to deflect around the axis, which is the axis of the cleaning component 3 and also the axis of the stopper. Figure 3 For example, the anchor chain 2 includes a transverse ring 21 and a vertical ring 22. Taking the transverse ring 21 as an example, the transverse ring 21 at the outlet of the cleaning component 3 is deflected by 3° to 15° around the axis relative to the transverse ring 21 at the inlet of the cleaning component 3. Specifically, the deflection angle of two adjacent limit members will decrease, wherein the longer the length of the cleaning component 3, the larger the corresponding deflection angle.

[0036] In this embodiment, by providing a deflection limiter, the anchor chain 2 will also deflect slightly when moving forward. Figure 5For example, when the transverse ring 21 just passes through the limiter, the cleaning member extends from the rightmost end of the transverse ring 21 into the inner side of the transverse ring 21 for grinding and cleaning. At this time, the cleaning member is also facing the plane where the transverse ring 21 is located. As the transverse ring 21 moves to the right, especially after the transverse ring 21 completely passes through the limiter, it will deflect slightly, and the cleaning member will remain in the position above the transverse ring 21. When the transverse ring 21 deflects, the cleaning member is already inside the transverse ring 21. The deflection of the transverse ring 21 will slightly squeeze the cleaning member, increase the grinding pressure, and improve the grinding effect. Similarly, although not shown in the figure, a side cleaning member can be set between other adjacent limiters so that it can extend into the vertical ring 22 to grind the inner side of the vertical ring 22.

[0037] refer to Figure 5~Figure 7 In a specific embodiment, the limiting member includes a limiting ring 33, and the limiting ring 33 is provided with a through hole and a guide member, so that the anchor chain 2 can be guided by the guide member and pass through the through hole smoothly.

[0038] In this embodiment, the anchor chain 2 can be guided to the through hole by providing a guide member, and the horizontal ring 21 or the vertical ring 22 is limited to pass through the through hole in a specific shape and at a specific angle, which makes it easy for the cleaning member to extend into the inner side of the chain ring for grinding and cleaning.

[0039] refer to Figure 6 or Figure 7 In a specific embodiment, the limiting ring 33 includes a disc-shaped plate body 331, a cross-shaped groove is provided at the center of one side of the plate body 331, and the bottom surface of the groove is an arc surface. Figure 6 The groove is composed of four sector-shaped grooves, and the center of the four sectors is the center of the plate body 331. The bottom surfaces of the sector-shaped grooves are all arc-shaped surfaces, and the depth of each sector-shaped groove gradually deepens from the sector-shaped arc edge to the sector-shaped center.

[0040] A cross-shaped center hole 332 is provided at the center of the groove, and the through hole is the center hole 332 .

[0041] The width of the groove is greater than the width of the center hole 332 , and a guide surface 333 is formed between the center hole 332 and the edge of the groove, and the guide member is the guide surface 333 .

[0042] The angle between the horizontal ring 21 and the vertical ring 22 in the existing anchor chain 2 is usually less than 90 degrees, and the horizontal ring 21 and the vertical ring 22 can be made perpendicular by twisting. Figure 6For example, by setting the groove, the horizontal ring 21 will contact the horizontal fan-shaped groove in the figure, and the vertical ring 22 will contact the vertical fan-shaped groove in the figure. At this time, the angle between the horizontal ring 21 and the vertical ring 22 is likely to be less than 90°. As the anchor chain 2 moves, the horizontal ring 21 and the vertical ring 22 will gradually move toward the center hole 332 along the guide surface 333, and gradually adjust the angle between the horizontal ring 21 and the vertical ring 22 so that the two are perpendicular to pass through the center hole 332. Of course, the width of the vertical hole in the center hole 332 can be slightly larger than the width of the vertical ring 22, and the width of the horizontal hole in the center hole 332 can be slightly larger than the width of the horizontal ring 21. In this way, the passability of the horizontal ring 21 and the vertical ring 22 can be better.

[0043] refer to Figure 5~Figure 7 In a specific embodiment, it further includes a plurality of ejection parts, which can eject liquid or granular solids to act on the inner side of the chain ring. The liquid can be water or a rust remover, and the granular solids can be quartz sand or steel sand. Preferably, the ejection part arranged on the stopper at the outlet of the cleaning component 3 ejects water, the ejection part arranged on the stopper at the inlet of the cleaning component 3 ejects rust remover, and the ejection part arranged on the stopper at the middle position of the cleaning component 3 ejects quartz sand or steel sand.

[0044] By setting a spraying part, when the spraying part sprays out the rust remover, the rust remover covers the surface of the anchor chain 2, and the chemical components in the rust remover can react chemically with the rust, so that the rust layer is loosened, dissolved or converted, and the rust layer tightly attached to the surface of the anchor chain 2 becomes loose, reducing the bonding force between the rust layer and the metal matrix, so that when the cleaning part is polished, the rust layer is easier to be removed, and the workload and time of polishing can be effectively reduced. Of course, whether to spray the rust remover needs to be determined according to the rust situation on the surface of the anchor chain 2. If the thickness of the rust on the surface of the anchor chain 2 is low or the rust is less, or there are other attachments, there is no need to use the rust remover. When the spraying part sprays out quartz sand or steel sand, the strong impact force of sandblasting can quickly clean the inside of the anchor chain 2, which has the advantage of high efficiency. Sandblasting also has the characteristics of strong directionality, and can accurately clean the inside of the anchor chain 2, so that the inside of the anchor chain 2 can be cleaned evenly and comprehensively. In addition, sandblasting can also form a certain roughness on the surface of the anchor chain 2 to increase the surface area. This rough surface is conducive to better adhesion of subsequent anti-corrosion coating or paint, thereby improving the bonding force between the coating and the surface of the anchor chain 2, extending the service life of the anti-corrosion coating, and enhancing the anti-corrosion performance of the anchor chain 2. If quartz sand is selected for sandblasting, the sandblasting process will not cause obvious damage to the base material of the anchor chain 2. When the spraying member sprays water, the spraying member is set at the outlet of the cleaning component 3, so that the surface of the anchor chain 2 can be washed to remove the debris of the surface grinding and cleaning.

[0045] By arranging the ejection member on the limiting ring 33, the limiting ring 33 can first limit the posture of the anchor chain 2, and fix the angle of the horizontal ring 21 or the vertical ring 22 of the limiting ring 33. The ejection member is arranged on the limiting ring 33. During the sandblasting process, the sand can be accurately sprayed on the inner side of the chain ring of the anchor chain 2, thereby effectively realizing the sandblasting cleaning process.

[0046] refer to Figure 5~Figure 7 In a specific embodiment, the ejection member includes at least one right-angle block 334. Specifically, the right-angle blocks 334 may be 1, 2, 3, 4, 5, 6, etc. Each right-angle block 334 is close to the midpoint of the through hole. Each right-angle block 334 is provided with two ejection holes 335. The opening directions of the two ejection holes 335 are perpendicular to each other. Figure 7 For example, the limiting ring 33 in the figure is provided with four right-angle blocks 334, each of which is arranged at a central position close to the center hole 332, and the two sides of the right-angle block 334 are respectively parallel to the horizontal hole and the vertical hole of the center hole 332. The spraying directions of the two spraying holes 335 on each right-angle block 334 are respectively perpendicular to the vertical hole in the center hole 332 and the horizontal hole in the center hole 332. Figure 5 For example, the vertical ring 22 in the figure is in the limit ring 33. At this time, the spray hole 335 below and perpendicular to the vertical hole 332 of the center hole can be sandblasted to clean and remove rust on the inside of the vertical ring 22. The sand sprayed by the sandblasting will scatter forward, and the actual effect is as follows: Figure 5 As shown in the example, the vertically arranged ejection holes 335 can primarily clean the inner side of the vertical ring 22 and secondarily clean the side of the vertical ring 22; similarly, Figure 5 Although not illustrated in the figure, the horizontally arranged ejection holes 335 can primarily clean the inner side of the transverse ring 21 and secondarily clean the side surfaces of the transverse ring 21 .

[0047] refer to Figure 1~Figure 4 In a specific embodiment, the cleaning component 3 includes a circular tube 31, the tube wall of the circular tube 31 is recessed outward to form a receiving box 32, and there is at least one receiving box 32 for receiving a cleaning member; the cleaning member includes a grinding brush 34, one end of the grinding brush 34 is hinged on the inner wall of the receiving box 32, and the other end of the grinding brush 34 can automatically approach the axis of the circular tube 31 and extend into the inner side of the chain ring for grinding.

[0048] In this embodiment, a receiving box 32 is provided to receive a grinding brush 34. The function of the grinding brush 34 in the figure is to grind the horizontal ring 21. When the vertical ring 22 passes, the grinding brush 34 can be stored in the receiving box 32, so that the vertical ring 22 can pass smoothly. It should be noted that although the grinding brush 34 is in the receiving box 32, it can still rotate to grind and clean the outer side of the vertical ring 22.

[0049] It should be noted that: taking the vertical ring 22 as an example, the spraying member can clean and remove rust from the inner side and the side of the vertical ring 22, and the horizontal grinding brush 34 can also grind and clean the inner side of the vertical ring 22 (not shown in the figure). Figure 4 When the grinding brushes 34 in the vertical direction are stored, the outer side of the vertical ring 22 can be polished. In other words, as long as at least four grinding brushes 34 in different directions are provided, in conjunction with the spraying member, basically every position of the anchor chain 2 can be cleaned.

[0050] refer to Figure 3~Figure 5 In a specific embodiment, the grinding brush 34 includes a grinding rod 341, one end of which is hinged on the inner wall of the receiving box 32, and the other end of which is connected to a flexible grinding head 343. The side wall of the grinding rod 341 is connected to the bottom wall of the receiving box 32 through a spring 344, and a protruding rod 342 is provided on the side wall of the grinding rod 341 away from the spring 344. By providing the protruding rod 342, before the outer side of the chain link of the anchor chain 2 contacts the grinding head 343, it first contacts the protruding rod 342, and the chain link directly contacts the protruding rod 342, driving the grinding rod 341 and the grinding head 343 to enter the receiving box 32. In this way, the chain link can be prevented from directly impacting the grinding head 343, thereby extending the service life.

[0051] A recovery box 35 and an air compressor 36 are provided at the bottom of the circular tube 31. The bottom of the circular tube 31 is open, and a recovery box 35 is provided below the opening.
