Description

Technical Field

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

[0002] An anchor chain is a steel chain connecting a hull and an anchor. The main functions of an anchor chain are: connecting the anchor and the ship and transmitting the holding force of the anchor to the hull; when anchoring, due to the certain weight of the thrown anchor chain, it can play a certain buffering role for the external forces such as wind and current acting on the ship in water; the anchor chain lying flat on the bottom of the water keeps the acting force on the anchor horizontal, which is beneficial to the reliable grounding 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 the anchor chain, due to the long-term immersion of the surface in seawater or river water and the wrapping of sludge, the surface of the anchor chain is severely corroded. Therefore, when repairing a ship, it is necessary to clean and remove rust from the surface of the anchor chain, completely remove the rust and sludge on the surface, expose the metal body, and then apply paint for anti-corrosion.

[0004] For the external cleaning and rust removal of some existing anchor chains, cleaning equipment is used, and the inner side of the anchor chain is usually cleaned and rust-removed manually. Taking a studless anchor chain as an example, for an anchor chain with a chain diameter of 50 mm, the theoretical weight is 50 Kg / m. According to ships of different volumes, the average length of the anchor chain is about 6 sections. It can be seen from this that the length of the anchor chain has exceeded 100 m, and the work difficulty and workload of manually cleaning and rust-removing the inner side of the anchor chain are very huge.

Specific Embodiments

[0037] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] Refer to Figures 1 to 7 , the present invention protects an anchor chain grinding device, which includes a first placement table 1, a cleaning assembly 3 and a second placement table 4. The height of the first placement table 1 in the vertical direction is higher than the height of the second placement table 4 in the vertical direction. The cleaning assembly 3 is inclined, and the angle between the axis of the cleaning assembly 3 and the ground is 25° to 50°. Specifically, it can be 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, 45°, 48° and 50°. The inlet of the cleaning assembly 3 is close to the first placement table 1, and the outlet of the cleaning assembly 3 is close to the second placement table 4. According to needs, the inlet end of the cleaning assembly 3 is connected to the first placement table 1, and the outlet end of the cleaning assembly 3 is connected to the second placement table 4. In this way, the unprocessed anchor chain 2, the anchor chain 2 being processed and the processed anchor chain 2 can be separated, enabling the anchor chain 2 to move orderly, and cooperating with the inclined cleaning assembly 3 can make the movement of the anchor chain 2 smoother.

[0039] 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 a tensile device so that the anchor chain 2 can move. Among them, the anchor chain 2 to be cleaned and derusted refers to the anchor chain 2 with dirt on its surface. The dirt can be substances with low adhesion such as mud and sand, oil stains, etc.; it can also be substances with high adhesion such as rust; it can also be a combination of both. In short, the anchor chain 2 to be cleaned and derusted needs to be cleaned. The tensile device is a conventional device that can provide tensile force. For example, it can be a winch, a tractor, an electric hoist, etc. The tensile device can pull the anchor chain 2 to move, so that the anchor chain 2 passes through the cleaning component 3, realizing the cleaning and derusting of the anchor chain 2.

[0040] The cleaning component 3 is provided with a plurality of limiting members and at least one cleaning member. The number of cleaning members can be 1, 2, 3, 4, 5, 6, etc., and can be correspondingly set according to the actual situation. The cleaning member is a device with a self-rotating grinding function. It can be a rigid grinding head, such as a tungsten carbide 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 derusting by means of grinding.

[0041] The limiting member can limit the passing angle of the anchor chain 2, so that the anchor chain 2 passes through the limiting member in a specific posture. The posture refers to the shape and deflection angle. It should be particularly noted that: there are a plurality of limiting members. In this application, passing through the limiting member in a specific posture means that the posture of the anchor chain 2 passing through one of the limiting members is the same. For example, there is a first limiting member and a second limiting member. The posture of each link in the anchor chain 2 after passing through the first limiting member is the same, and the posture of each link in the anchor chain 2 after passing through the second limiting member is also the same. However, the posture of the link after passing through the first limiting member and the posture of the link after passing through the second limiting member can be the same or different.

[0042] A plurality of links are provided on the anchor chain 2, and the cleaning member can extend into the inner side of the link for grinding, cleaning and derusting. The inner side of the link is the side wall of the inner ring of the link.

[0043] By providing the first placement table 1 and the second placement table 4, the present invention can place the anchor chain 2 on the first placement table 1. The first placement table 1 is used to bear the main weight of the uncleaned anchor chain 2, and the second placement table 4 is used to bear the cleaned anchor chain 2. During the cleaning operation, only the section to be cleaned and derusted is put into the cleaning component 3 for treatment. This not only facilitates controlling the moving speed of the anchor chain 2 in the cleaning component 3, but also prevents the main weight of the anchor chain 2 from pressing on the cleaning component 3 and damaging the cleaning component 3.

[0044] By providing the cleaning member, the cleaning member has a grinding function and can grind, clean and derust the anchor chain 2. By providing the limiting member, the present invention can limit the passing angle of the anchor chain 2 in the cleaning and derusting section, so that the anchor chain 2 passes through the limiting member in the same posture. Figure 5For example, the anchor chain 2 has horizontal rings 21 and vertical rings 22. When the vertical ring 22 passes through the limiting member, the ring hole of the horizontal ring 21 is facing the cleaning member, enabling the cleaning member to extend into the inside of the horizontal ring 21 for grinding and cleaning, facilitating the cleaning member to extend into the inside of the chain link for grinding, cleaning, and rust removal. Setting multiple limiting members can also keep the anchor chain 2 as straight as possible within the cleaning assembly 3, facilitating the grinding and cleaning of the cleaning member.

[0045] In the present invention, by setting the inclined cleaning assembly 3, compared with the vertically arranged cleaning assembly 3, the anchor chain 2 entering the cleaning assembly 3 can move slowly under the action of gravity, facilitating controlling the moving speed of the anchor chain 2 within the cleaning assembly 3 through the tension device. This has two functions. The first function is to enable the cleaning member to extend into the inside of the chain link for sufficient grinding, cleaning, and rust removal; the second function is to enable the anchor chain 2 to pass through the limiting member more precisely, achieving the conversion of the posture.

[0046] 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 pausing for 5 s to 15 s. During the pause, the anchor chain 2 will move slightly or not move, so that there is enough time for the cleaning member to complete the action of extending into the chain link of the anchor chain 2 and effectively grinding the inside. At the same time, during the pause, the cleaning of the same position by the cleaning member can also be extended, improving the grinding and cleaning effect.

[0047] Reference Figures 1 to 3 , in a specific embodiment, the first placement table 1 includes a table board 11 and an inclined groove 12 provided on the table board 11. The inclined groove 12 can be directly opened on the surface of the table board 11; or it can be an inclined groove 12 with an inclined shape externally connected to one end of the table board 11.

[0048] Deceleration members are provided on both the inner surface of the inclined groove 12 and the limiting member. The friction coefficient of the deceleration member is above 0.3, and the deceleration member can decelerate the anchor chain 2 by contact friction. Among them, the deceleration members provided on the inner surface of the inclined groove 12 and the limiting member can be of the same material or different materials. For example, the deceleration members provided on the inner surface of the inclined groove 12 and the limiting member can both be the first deceleration member; or the deceleration member provided on the inner surface of the inclined groove 12 is the first deceleration member, and the deceleration member provided on the limiting member is the second deceleration member. Of course, the deceleration members on multiple limiting members can also be different, and can be the first deceleration member, the second deceleration member, the third deceleration member, the fourth deceleration member, etc. respectively.

[0049] The deceleration member provided in this embodiment has two functions. Reference Figure 3, the first function is: to slow down the downward movement speed of the anchor chain 2. When the angle of the cleaning component 3 is relatively large, the anchor chain 2 is more likely to slide down. There may be a situation where the pulling device does not provide pulling force, and the anchor chain 2 itself will move downward along the cleaning component 3 relatively quickly. Setting the decelerating member can provide frictional force to slow down the downward movement speed of the anchor chain 2 itself, and try to make the anchor chain 2 move downward only through the pulling 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 its cleaning role. The second function is: to try to straighten the anchor chain 2 as much as possible. Taking Figure 3 as an example, the anchor chain 2 is arranged inside the cleaning component 3. Multiple limiting members can make the anchor chain 2 as straight as possible. However, the anchor chain 2 between adjacent limiting members may bend downward under the action of gravity. After setting the decelerating member, under the pulling of the pulling device and the action of the reverse frictional force of the decelerating member, the anchor chain 2 can be made as straight as possible, which is convenient for the grinding and cleaning of the cleaning member. More importantly, when the pulling device pauses, there is a decelerating member on the limiting member, which can have a relatively large frictional force on the anchor chain 2, and overcome the gravity of the anchor chain 2 between the two limiting members to a certain extent, making the anchor chain 2 as straight as possible, which is convenient for the grinding and cleaning of the cleaning member.

[0050] Preferably, the material of the decelerating 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 frictional force between rubber and iron is 0.6, and the frictional force is relatively large. The friction coefficient of polyurethane is about 0.5, and moreover, if it is in a working condition with wetting media such as water and oil, its wear resistance is often several times to dozens of times that of ordinary rubber materials. The friction coefficient of ceramic is also about 0.5, and it itself has strong wear resistance. In addition, the thermal stability of ceramic is high. Taking ceramic brake pads as an example, even when the temperature of the brake disc is as high as 650 °C, its friction coefficient can still remain at about 0.45 to 0.55. The decelerating member on the limiting member is preferably made of ceramic. In this way, when the limiting member heats up, the decelerating member on the limiting member can still maintain a certain frictional force.

[0051] Refer to Figure 3 and Figure 5 , in a specific embodiment, there is a deflection angle between adjacent limiting members, so that after the anchor chain 2 passes through the limiting member, the anchor chain 2 will deflect around its own axis. In this embodiment, there is a deflection angle between adjacent limiting members, and the deflection method is to deflect around the axis, and this axis is the axis of the cleaning component 3 and also the axis of the limiting member. Taking Figure 3 as an example, the anchor chain 2 includes a horizontal ring 21 and a vertical ring 22. Taking the horizontal ring 21 as an example, the horizontal ring 21 at the outlet of the cleaning component 3 deflects 3° to 15° around the axis relative to the horizontal ring 21 at the inlet of the cleaning component 3. Specifically, the deflection angle between adjacent two limiting members will decrease, and among them, the longer the length of the cleaning component 3, the larger the corresponding deflection angle.

[0052] In this embodiment, by providing a deflected limiting member, when the anchor chain 2 moves forward, it will also deflect slightly. For Figure 5 example, when the horizontal ring 21 just passes through the limiting member, the cleaning member extends into the inner side of the horizontal ring 21 from the rightmost end of the horizontal ring 21 for grinding and cleaning. At this time, the cleaning member is also facing the plane where the horizontal ring 21 is located. As the horizontal ring 21 moves to the right, especially after the horizontal ring 21 completely passes through the limiting member, it will deflect slightly. The position of the cleaning member above the horizontal ring 21 remains unchanged. When the horizontal ring 21 deflects, the cleaning member is already inside the horizontal ring 21. The deflection of the horizontal ring 21 will slightly squeeze the cleaning member, increasing the grinding pressure and improving the grinding effect. Similarly, although not shown in the figure, side cleaning members can be provided between other adjacent limiting members so that they can extend into the vertical ring 22 to grind the inner side of the vertical ring 22.

[0053] Reference Figures 5 to 7 , in a specific embodiment, the limiting member includes a limiting ring 33. The limiting ring 33 is provided with a through hole and a guiding member, so that the anchor chain 2 can be guided by the guiding member and smoothly pass through the through hole.

[0054] In this embodiment, by providing the guiding member, the anchor chain 2 can be guided to the through hole. When the horizontal ring 21 or the vertical ring 22 enters the through hole, it is limited to pass through in a specific shape and at a specific angle, which is convenient for the cleaning member to extend into the inner side of the chain link for grinding and cleaning.

[0055] Reference 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. Reference Figure 6 , the groove is composed of four fan-shaped grooves, and the centers of the four fans are the center of the plate body 331. The bottom surfaces of the fan-shaped grooves are all arc surfaces, and the depth of each fan-shaped groove gradually increases from the arc edge of the fan to the center of the fan.

[0056] A cross-shaped center hole 332 is provided at the center of the groove, and the through hole is the center hole 332.

[0057] The width of the groove is greater than the width of the center hole 332. A guiding surface 333 is formed between the center hole 332 and the edge of the groove, and the guiding member is the guiding surface 333.

[0058] The included angle between the horizontal ring 21 and the vertical ring 22 in the existing anchor chain 2 is usually less than 90°. By twisting, the horizontal ring 21 and the vertical ring 22 can be made perpendicular. For Figure 6For example, by setting the grooves, the horizontal ring 21 will come into contact with the fan-shaped grooves in the horizontal direction in the figure, and the vertical ring 22 will come into contact with the fan-shaped grooves in the vertical direction in the figure. At this time, the included 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 towards the central hole 332 along the guiding surface 333, and the included angle between the horizontal ring 21 and the vertical ring 22 is also gradually adjusted to be perpendicular to each other to pass through the central hole 332. Of course, the width of the vertical hole in the central hole 332 can be slightly larger than the width of the vertical ring 22, and the width of the horizontal hole in the central hole 332 can be slightly larger than the width of the horizontal ring 21. In this way, the passing performance of the horizontal ring 21 and the vertical ring 22 can be better.

[0059] Reference Figures 5 to 7 , in a specific embodiment, it further includes a plurality of spraying members, and the spraying members can spray liquid or particulate solid onto the inner side of the chain link. Among them, the liquid can be water or rust remover, and the particulate solid is quartz sand or steel shot. Preferably, the spraying member provided on the limiting member at the outlet of the cleaning assembly 3 sprays water, the spraying member provided on the limiting member at the inlet of the cleaning assembly 3 sprays rust remover, and the spraying member provided on the limiting member at the middle position of the cleaning assembly 3 sprays quartz sand or steel shot.

[0060] By setting the spraying members, when the spraying members spray rust remover, the rust remover covers the surface of the anchor chain 2. The chemical components in the rust remover can chemically react with the rust, loosen, dissolve or transform the rust layer, make the rust layer tightly attached to the surface of the anchor chain 2 become loose, and reduce the bonding force between the rust layer and the metal matrix. In this way, when the cleaning member polishes, the rust layer is more easily removed, which can effectively reduce the workload and time of polishing. Of course, whether to spray rust remover needs to be determined according to the rust situation on the surface of the anchor chain 2. If the rust thickness on the surface of the anchor chain 2 is low, there is less rust, or there are other attachments, then there is no need to use rust remover. When the spraying members spray quartz sand or steel shot, the strong impact force of sandblasting can quickly clean the inner side of the anchor chain 2, which has the advantage of high efficiency. Sandblasting also has the characteristic of strong directivity, which can accurately clean the inner side of the anchor chain 2, so that the inner side of the anchor chain 2 can be evenly and comprehensively cleaned. In addition, sandblasting can also make the surface of the anchor chain 2 form a certain roughness, increasing the surface area. This rough surface is beneficial for the subsequent anti-corrosion coating or paint to better adhere, 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. When quartz sand is selected for sandblasting, the sandblasting treatment will not cause obvious damage to the base material of the anchor chain 2. When the spraying member sprays water, the spraying member is arranged at the outlet of the cleaning assembly 3, so that it can wash the surface of the anchor chain 2 and remove the debris from the surface grinding and cleaning.

[0061] By arranging the spraying part on the limiting ring 33, the limiting ring 33 can first limit the posture of the anchor chain 2. Through the angle fixation of the horizontal ring 21 or the vertical ring 22 of the limiting ring 33, and the spraying part is arranged on the limiting ring 33. During the sandblasting process, the sand can be accurately sprayed inside the link of the anchor chain 2, effectively realizing the sandblasting cleaning treatment.

[0062] Reference Figures 5 to 7 , in a specific embodiment, the spraying part includes at least one right-angle block 334. Specifically, the number of right-angle blocks 334 can be 1, 2, 3, 4, 5, 6, etc. Each right-angle block 334 is close to the midpoint of the through-hole, and two spraying holes 335 are provided on each right-angle block 334, and the opening directions of the two spraying holes 335 are perpendicular to each other. Taking Figure 7 as an example, there are 4 right-angle blocks 334 arranged on the limiting ring 33 in the figure. Each right-angle block 334 is arranged at the central position close to the central hole 332, and both sides of the right-angle block 334 are parallel to the horizontal hole and the vertical hole of the central hole 332 respectively. The spraying directions of the two spraying holes 335 on each right-angle block 334 are perpendicular to the vertical hole and the horizontal hole in the central hole 332 respectively. During specific operation, taking Figure 5 as an example, the vertical ring 22 in the figure is inside the limiting ring 33. At this time, the sandblasting treatment of the spraying hole 335 perpendicular to the vertical hole of the central hole 332 below can clean and remove rust from the inner side of the vertical ring 22. The sand sprayed during the sandblasting treatment will scatter forward. The actual effect is that, as Figure 5 shown in the example, the spraying holes 335 arranged vertically can mainly clean the inner side of the vertical ring 22 and simultaneously conduct secondary cleaning on the side surface of the vertical ring 22; similarly, Figure 5 not shown in the example, the spraying holes 335 arranged horizontally can mainly clean the inner side of the horizontal ring 21 and simultaneously conduct secondary cleaning on the side surface of the horizontal ring 21.

[0063] Reference Figures 1 to 4 , in a specific embodiment, the cleaning assembly 3 includes a circular tube 31. The tube wall of the circular tube 31 is recessed outward to form a receiving box 32. There is at least one receiving box 32 for receiving the cleaning parts; the cleaning parts include a polishing brush 34. One end of the polishing brush 34 is hinged to the inner wall of the receiving box 32, and the other end of the polishing brush 34 can automatically approach the axis of the circular tube 31 and extend into the inner side of the link for polishing.

[0064] In this embodiment, by arranging the receiving box 32, the polishing brush 34 can be received. The function of the polishing brush 34 in the figure is to polish the horizontal ring 21. When the vertical ring 22 passes by, the polishing brush 34 can be received into the receiving box 32 to allow the vertical ring 22 to pass through smoothly. It should be noted that although the polishing brush 34 is inside the receiving box 32, it can still rotate to polish and clean the outer side surface of the vertical ring 22.

[0065] 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.

[0066] refer to Figures 3 to 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.

[0067] 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. The sand after the blasting of the ejected part can be recovered into the recovery box 35 for subsequent reuse. The air compressor 36 is provided as a power source for the sandblasting action.

[0068] The anchor chain grinding device in the present application can realize the grinding, cleaning and rust removal of the inner side of the anchor chain 2 chain link to the greatest extent, but it cannot guarantee complete and thorough cleaning without any doubt, and individual positions of individual chain links after treatment may need further manual treatment. However, it still does not affect the fact that the present application can greatly reduce the workload and work difficulty of the staff.

[0069] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
