Description

Technical Field

[0001] The invention belongs to the technical field of ship rust removal, in particular to a multi-degree-of-freedom ship ultra-high pressure water rust removal device. Background Art

[0002] As the core carrier of maritime transportation, the maintenance and care of ships is extremely important. Ships are in harsh marine environments for a long time, and the surface of the hull will be corroded by seawater, sea breeze, salt spray, and marine organisms, resulting in rust. The rust layer will not only affect the appearance of the ship, but more importantly, it will weaken the strength and durability of the hull structure. Therefore, it is necessary to regularly remove rust from the outer surface of the ship, and the ultra-high pressure water rust removal device is one of the methods for rust removal. The rotating cross-shaped rotating frame on the device drives the nozzle to rotate, and ultra-high pressure water is sprayed to the outer surface of the ship through the nozzle to remove the rust on the outer surface of the ship.

[0003] In the prior art, high-pressure water is sprayed onto the surface of the ship through the nozzles and guide nozzles on the device to remove rust, and the sewage generated in the rust removal process is discharged outward through the sewage pipe. However, in the process of spraying rust removal, some stubborn rust on the outer surface of the ship may not be completely removed only by spraying rust with high-pressure water, which will result in incomplete rust removal and reduce the rust removal effect on the rust on the surface of the ship. In addition, the sewage generated in the rust removal process is easy to splash out through the bottom gap of the mounting plate, causing the problem of sewage polluting the environment. For this reason, we propose a multi-degree-of-freedom ship ultra-high-pressure water rust removal device. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention adopts a designed grinding mechanism, which drives the outer ring frame to rotate through a driving motor, thereby driving the grinding plate to rotate to remove the rust on the ship. The strip brush located at the bottom of the cross-shaped rotating frame can further assist in rust removal and sweep away the rust residue after rust removal, thereby realizing a variety of rust removal methods combining ultra-high pressure water jetting with grinding. Different types and degrees of rust can be treated more effectively, thereby improving the rust removal effect and efficiency. At the same time, the grinding plate, connecting seat, telescopic plate and outer ring frame can block and protect the splashed sewage, sprayed high-pressure water and rust residue generated by grinding during the grinding process, thereby reducing the probability of sewage, sprayed high-pressure water and rust residue generated by grinding splashing outward.

[0020] (2) The auxiliary grinding parts designed in the present invention can also drive the grinding head to rotate during the rotation of the outer ring frame to further grind the rust on the surface of the ship, thereby increasing the effect of removing rust on the surface of the ship. At the same time, the connecting spring can make the grinding head have a tendency to continue to squeeze and move toward the surface of the ship during the grinding process, thereby further improving the effect of the grinding head on removing rust on the surface of the ship.

[0021] (3) The present invention adopts a designed blocking component, in which the protective plate and the wear-resistant plate are fixed on the outer wall of the cross-shaped rotating frame. This can not only reduce the amount of water splashing outward during the process of spraying high-pressure water onto the surface of the ship, but also provide blocking protection through the protective plate and the wear-resistant plate. In addition, during the process of high-pressure water rust removal, rust residue, sewage and other impurities will be generated. The protective plate and the wear-resistant plate can prevent these impurities from directly impacting and eroding the inner wall of the mounting plate, thereby reducing the wear and damage to the mounting plate components, extending the service life of the equipment, and ensuring the stability and reliability of the device. In addition, the rolling ball located on the top of the protective plate contacts the inner wall of the mounting plate. Through the rolling ball, the protective plate can reduce the probability of wear on the contact portion of the top mounting plate during the rotation of the cross-shaped rotating frame.

[0022] (4) The scraper designed in the present invention can timely scrape off the rust residue attached to the inner wall of the wear-resistant plate during the ship rust removal process to prevent the rust residue from accumulating on the wear-resistant plate. This not only helps to keep the wear-resistant plate clean and the inner wall of the wear-resistant plate smooth, but also ensures that the protective plate and the wear-resistant plate are always in good working condition and maintain their protective function for the mounting plate. At the same time, it can also make the high-pressure water ejected from the guide jet port splash onto the inner wall surface of the wear-resistant plate and then reflect to the surface of the ship below, thereby increasing the rust removal effect on the ship surface.

DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0040] Embodiment 1

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.14 and Fig.15 The present invention provides a technical solution: a multi-degree-of-freedom ship ultra-high pressure water rust removal device, comprising a small arm 103, a mounting plate 105 and a cross-shaped rotating frame 108 rotatably arranged at the bottom of the mounting plate 105, the cross-shaped rotating frame 108 is respectively provided with a plurality of nozzles 109 and a plurality of guide injection ports 112, a grinding mechanism is arranged on the mounting plate 105, and the grinding mechanism comprises a rotating grinding component and a telescopic component;

[0042] The rotating grinding assembly includes an outer ring frame 200 and multiple groups of connecting seats 216 arranged at the bottom of the mounting plate 105. The outer ring frame 200 is rotatably arranged on the mounting plate 105. A grinding plate 215 is fixedly arranged at the bottom of the connecting seat 216. A telescopic plate 214 is fixedly arranged between the top of the connecting seat 216 and the outer ring frame 200. When the connecting seat 216 on the grinding plate 215 moves up and down, the telescopic plate 214 plays a role in blocking and protecting the connecting seat 216 and the upper outer ring frame 200. Multiple groups of strip brushes 204 are fixedly arranged at the bottom of the cross-shaped rotating frame 108. When the cross-shaped rotating frame 108 rotates, it can also drive the strip brush 204 below to rotate. At this time, the strip brush 204 can sweep the rust residue generated after the high-pressure water is sprayed on the surface of the ship, so that the rust residue can easily and smoothly enter the sewage pipe 107, and the rotating strip brush 204 can sweep the rust on the surface of the ship, thereby increasing the effect of removing the rust.

[0043] A sewage pipe 107 is fixedly provided on the outer wall of the mounting plate 105, and a pipeline is connected to the bottom of the sewage pipe 107, so that rust residue and sewage in the rust removal process can enter the sewage pipe 107 from the entrance of the sewage pipe 107 in the mounting plate 105 and then be discharged outward through the pipeline, thereby reducing the pollution to water resources. A driving member is provided between the sewage pipe 107 and the outer ring frame 200, and the driving member includes a driving motor 201 and a worm 202 fixed on the sewage pipe 107. A fixing column 206 is fixedly provided on the outside of the driving motor 201, and the top of the worm 202 is rotatably provided inside the fixing column 206. A worm gear 205 is fixedly provided on the working end of the driving motor 201, and the worm gear 205 is meshed with the worm 202. A driving wheel 207 is fixedly provided on the bottom of the worm 202, and the driving wheel 207 contacts the outer wall of the outer ring frame 200.

[0044] The telescopic assembly includes multiple groups of fixed blocks 218 fixed on the outer wall of the outer ring frame 200 and multiple groups of semicircular plates 219 fixed on the outer wall of the connecting seat 216. An L-shaped slide plate 212 is slidably arranged inside the fixed block 218. The bottom of the L-shaped slide plate 212 extends to the upper surface of the semicircular plate 219. A mounting spring 217 is fixedly arranged between the top of the L-shaped slide plate 212 and the fixed block 218.

[0045] The present invention uses a designed grinding mechanism to drive the outer ring frame 200 to rotate through the driving motor 201, which drives the grinding plate 215 to rotate to remove rust on the ship. The strip brush 204 located at the bottom of the cross-shaped rotating frame 108 can further assist in rust removal and sweep and clean the rust residue after rust removal, thereby realizing a variety of rust removal methods combining ultra-high pressure water jetting with grinding. Different types and degrees of rust can be treated more effectively, and the rust removal effect and efficiency are improved. At the same time, the grinding plate 215, the connecting seat 216, the telescopic plate 214 and the outer ring frame 200 can block and protect the sewage splashed during the grinding process, the high-pressure water sprayed and the rust residue generated by the grinding, thereby reducing the probability of sewage, high-pressure water sprayed and the rust residue generated by the grinding splashing outward.

[0046] In summary, the bottom of the outer ring frame 200 is brought into contact with the surface of the ship, and the multiple groups of grinding plates 215 are also brought into contact with the surface of the ship. At this time, the device is turned on and the device is put into operation. The device and the grinding plates 215 move up, down, left and right on the surface of the ship, and ultra-high pressure water is ejected outward from the multiple nozzles 109 at the bottom of the cross-shaped rotating frame 108 and the multiple groups of guide injection ports 112 on the side. After the water is ejected outward through the guide injection ports 112, the cross-shaped rotating frame 108 can be driven to rotate. The high-pressure water ejected from the nozzles 109 and the water ejected from the guide injection ports 112 and splashed onto the inner wall of the mounting plate 105 and scattered together remove the rust on the ship. At the same time, the driving motor 201 is turned on, and the working end of the driving motor 201 drives the worm gear 205 to rotate, the worm gear 205 drives the worm 202 to rotate, and the worm 202 drives the driving wheel 207 Rotate, then the rotating driving wheel 207 drives the outer ring frame 200 to rotate, and the outer ring frame 200 drives the telescopic plate 214, the fixed block 218, the L-shaped slide plate 212, the connecting seat 216 and the grinding plate 215 and other structures to rotate, and then the rust on the surface of the ship is polished by the rotating grinding plate 215, and the rust on the surface of the ship is removed by the ejected high-pressure water during the grinding process, thereby increasing the rust removal effect on the rust, and during the rust removal process of the grinding plate 215 rotating, the spring 217 can continuously provide the grinding plate 215 with a force approaching the surface of the ship, and at this time, the L-shaped slide plate 212 slides up and down in the fixed block 218, so that the grinding plate 215 on the connecting seat 216 can always fit on the surface of the ship according to the different curved surfaces of the ship surface, thereby increasing the grinding and rust removal performance of the grinding plate 215.

[0047] Embodiment 2

[0048] Based on Example 1, please refer to Figure 1-Figure 7A plurality of auxiliary grinding parts are arranged on the outer ring frame 200, and the auxiliary grinding parts include a T-shaped rod 211 slidably arranged inside the outer ring frame 200, and the T-shaped rod 211 can move up and down inside the outer ring frame 200. A grinding head 203 is fixedly arranged at the bottom of the T-shaped rod 211, and a connecting spring 213 is sleeved on the outside of the T-shaped rod 211. The top and bottom of the connecting spring 213 are respectively fixed on the T-shaped rod 211 and the outer ring frame 200.

[0049] The auxiliary grinding parts designed in the present invention can also drive the grinding head 203 to rotate during the rotation of the outer ring frame 200 to further grind the rust on the surface of the ship, thereby increasing the effect of removing rust on the surface of the ship. At the same time, the connecting spring 213 can make the grinding head 203 during the grinding process have a tendency to continue to squeeze and move toward the surface of the ship, thereby further improving the effect of removing rust on the surface of the ship by the grinding head 203.

[0050] In summary, during the rotation of the outer ring frame 200, multiple groups of T-shaped rods 211 will also be driven to rotate. The T-shaped rods 211 drive the multiple groups of grinding heads 203 below to rotate. The lower surface of the grinding head 203 contacts the surface of the ship. At this time, the rotating grinding head 203 can grind and remove the rust on the surface of the ship again. At the same time, during the grinding process, the connecting spring 213 can make the T-shaped rod 211 generate a force that continues to approach the surface of the ship, thereby making the grinding head 203 continue to approach the surface of the ship, allowing the grinding head 203 to fit the surface of the ship with different curves, thereby increasing the effect of the grinding head 203 on grinding and removing rust on the surface of the ship.

[0051] Embodiment 3

[0052] Based on Example 2, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11, a plurality of blocking components are arranged outside the cross-shaped rotating frame 108, and the blocking components include a protective plate 208 fixed on the outer wall of the cross-shaped rotating frame 108. During the rust removal process, rust residue will splash in all directions, and more rust residue will fly to the inner wall surface of the mounting plate 105 close to the protective plate 208, while the area above the inner wall of the mounting plate 105 is less splashed with rust residue. Therefore, it is necessary to increase the protection of the area close to the protective plate 208 and the inner wall of the mounting plate 105, and increase the protection of the inner wall of the mounting plate 105 close to the protective plate 208. Plate 208, the inner wall of the protective plate 208 is provided with a wear-resistant plate 209, and the wear-resistant plate 209 and the protective plate 208 are connected by mounting bolts 210. When the wear-resistant plate 209 is worn out after being used for a long time, the wear-resistant plate 209 can be disassembled and replaced to reduce the replacement cost. The inner wall of the wear-resistant plate 209 is provided with multiple groups of countersunk holes, and the inside of the countersunk holes is provided with mounting bolts 210, and the working end of the mounting bolt 210 extends to the inside of the protective plate 208. The top of the protective plate 208 is provided with multiple groups of rolling balls 220, and the multiple groups of rolling balls 220 are staggered.

[0053] The present invention adopts a designed blocking component, in which the protective plate 208 and the wear-resistant plate 209 are fixed on the outer wall of the cross-shaped rotating frame 108, which can not only reduce the amount of water splashing outward during the process of spraying high-pressure water onto the surface of the ship, but also provide blocking protection through the protective plate 208 and the wear-resistant plate 209. In addition, in the process of high-pressure water rust removal, impurities such as rust residue and sewage will be generated. The protective plate 208 and the wear-resistant plate 209 can block these impurities from directly impacting and eroding the inner wall of the mounting plate 105, reduce the wear and damage to the components of the mounting plate 105, extend the service life of the equipment, and ensure the stability and reliability of the device. In addition, the rolling ball 220 located on the top of the protective plate 208 contacts the inner wall of the mounting plate 105. Through the rolling ball 220, the protective plate 208 can reduce the probability of wear on the contact part of the top mounting plate 105 during the rotation of the cross-shaped rotating frame 108.

[0054] In summary, a lot of impurities such as rust residue and sewage will be generated during the rust removal process, and these impurities will splash outward and hit the inner wall surface of the mounting plate 105. At this time, the wear-resistant plates 209 on the multiple sets of protective plates 208 installed on the cross-shaped rotating frame 108 can block the rust residue and sewage splashing onto the inner wall of the mounting plate 105, thereby preventing the rust residue from splashing onto the inner wall surface of the mounting plate 105 and causing the probability of wear and damage to the inner wall surface of the mounting plate 105. In addition, the telescopic plate 214, the grinding plate 215 and the connecting seat 216 can block the rust residue and sewage splashing outward, thereby reducing the rust residue and sewage from the bottom of the mounting plate 105 and the loose fit between the surface of the ship. In order to reduce the probability of splashing out from the gap, when the protective plate 208 rotates with the cross-shaped rotating frame 108, the ball 220 above will be driven to roll, which can not only increase the stability of the protective plate 208 during rotation, but also avoid the probability of wear caused by the contact between the upper side of the protective plate 208 and the inner wall of the mounting plate 105. At the same time, multiple groups of balls 220 are arranged crosswise, and the cross-arranged balls 220 can block the rust residue splashing out from the gap between the protective plate 208 and the inner wall of the mounting plate 105, thereby reducing the probability of rust residue splashing out from the gap between the ball 220 and the inner wall of the mounting plate 105 and hitting the inner wall surface of the mounting plate 105.

[0055] Embodiment 4

[0056] Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 Fig.14 and Fig.15 The protective plate 208 is provided with a scraping member for scraping off some rust residue attached to the inner wall of the wear-resistant plate 209. The scraping member includes a scraping strip 302 slidably arranged on the inner wall of the wear-resistant plate 209 and an electromagnet 304 fixed on the inner wall of the protective plate 208. The inner wall of the electromagnet 304 is embedded with a mounting motor 306. A screw rod 301 is fixedly arranged on the working end of the mounting motor 306. A connecting wire 305 is arranged on the top of the electromagnet 304 and the mounting motor 306. A waterproof conductive slip ring is installed inside the mounting disk 105. The top of the connecting wire 305 contacts the rotating part of the waterproof conductive slip ring, and the stationary part of the waterproof conductive slip ring is fixed on the mounting disk 105. The electromagnet 304 and the mounting motor 306 are powered by the waterproof conductive slip ring. The waterproof conductive slip ring is connected to the outside through an electric wire. The mounting motor 306 is a waterproof motor.

[0057] An iron plate 307 is fixedly provided on the inner wall of the scraper strip 302, a nut seat 308 is provided on the outside of the screw rod 301, the iron plate 307 is fixedly connected to the nut seat 308, a convex plate 300 is fixedly provided on the inner wall of the cross-shaped rotating frame 108, the screw rod 301 extends to the surface of the convex plate 300, and the bottom of the screw rod 301 is rotatably provided on the convex plate 300.

[0058] The scraper designed in the present invention can scrape off the rust residue adhered to the inner wall of the wear-resistant plate 209 during the rust removal process of the ship in time to avoid the accumulation of rust residue on the wear-resistant plate 209, which not only helps to keep the wear-resistant plate 209 clean and the inner wall of the wear-resistant plate 209 smooth, but also ensures that the protective plate 208 and the wear-resistant plate 209 are always in good working condition and maintain their protective function for the mounting plate 105. At the same time, it can also make the high-pressure water ejected from the guide injection port 112 splash onto the inner wall surface of the wear-resistant plate 209 and then reflect to the surface of the ship below, thereby increasing the rust removal effect on the ship surface.

[0059] In summary, during the rust removal process, some rust residue is easy to splash and adhere to the inner wall surface of the wear-resistant plate 209. When too much rust residue accumulates, the surface of the wear-resistant plate 209 will become rough. At this time, it is cleaned by a scraper. When cleaning, first turn off the electromagnet 304 and the rust removal device. At this time, the iron plate 307 adsorbed on the electromagnet 304 is no longer adsorbed, and the fixed restriction on the scraper strip 302 is released. Then, the installation motor 306 located on the electromagnet 304 is turned on. The installation motor 306 drives the screw rod 301 to rotate, which can drive the nut seat 308 located on the screw rod 301 to move downward, driving the iron plate 307 and the scraper strip 302 to move. At this time, the scraper strip 302 can be opened. The rust residue attached to the inner wall surface of the wear-resistant plate 209 and the rust residue attached to the outer wall of the cross-shaped rotating frame 108 and the surface of the guide injection port 112 are scraped off. When the nut seat 308 moves downward to a suitable position, the installation motor 306 is reversed. At this time, the nut seat 308 and the scraper bar 302 move upward. This is repeated. The rust residue attached to the surface of the wear-resistant plate 209 is scraped off by the up and down movement of the scraper bar 302. When the scraping is completed, the upper side of the iron plate 307 is brought into contact with the electromagnet 304, and then the electromagnet 304 is turned on. At this time, the electromagnet 304 adsorbs the lower iron plate 307 and the electromagnet 304 together, and the scraper bar 302 is adsorbed, limited and fixed.

[0060] In this embodiment, a C-shaped arm frame 104 is rotatably provided at one end of the small arm 103, and both ends of the C-shaped arm frame 104 are rotatably connected to the mounting plate 105 via a rotating shaft.

[0061] In this embodiment, a slewing drive seat 101 is rotatably provided at the other end of the forearm 103, and a mounting seat 100 is fixedly provided on the slewing drive seat 101. A cylinder 102 is provided between the forearm 103 and the slewing drive seat 101. During use, the mounting seat 100 is installed on a mobile lifting device for use, and the rust removal device can be raised, lowered and moved by the mobile lifting device. During use, the angle between the forearm 103 and the slewing drive seat 101 can be adjusted by the cylinder 102, the angle between the C-shaped arm frame 104 and the forearm 103 can be rotated to adjust the angle, and the mounting plate 105 and the C-shaped arm frame 104 can be rotated to adjust the angle of the mounting plate 105. Through the above series of rotations, the bottom of the mounting plate 105 can be attached to the surface of the ship with different curves, thereby realizing multi-degree-of-freedom rotation of the mounting plate 105 and the cross-shaped rotating frame 108.

[0062] In this embodiment, a water inlet pipe and a limiting plate 110 are respectively provided on the rust removal seat 106. The water inlet pipe is connected to a pipe for supplying ultra-high pressure water from the outside. When the mounting plate 105 and the C-shaped arm frame 104 rotate, the mounting plate 105 will drive the limiting plate 110 to rotate. At this time, the L-shaped limiting frame 111 is used to limit the rotation angle of the rotating mounting plate 105 to a certain extent to avoid the mounting plate 105 from rotating too much. An L-shaped limiting frame 111 is fixedly provided on the C-shaped arm frame 104.

[0063] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
