Description

Technical Field

[0001] This invention relates to the field of ship rust removal technology, and in particular to a dock bottom rust removal disc and dock bottom rust removal vehicle for improving edge adhesion. Background Technology

[0002] During their service life, ships are constantly immersed in seawater and subject to its erosion. As ships operate at sea for longer periods, oxidation and rust inevitably occur on the outer walls and decks. Oxidation and rust affect the service life of ships, and if the rust becomes more severe, it can cause irreversible damage to the hull. Therefore, it is necessary to remove rust from ships in a timely manner to reduce the corrosion caused by rust and extend the service life of ships.

[0003] Ship rust removal machinery has gone through three development stages: abrasive jet rust removal, ultra-high pressure pure water jet rust removal, and ultra-high pressure pure water jet vacuum rust removal technology. Water-plus-sand abrasive jet rust removal has made water-based rust removal a reality, significantly reducing environmental pollution. Currently, common ship hull rust removal robots mainly consist of a trolley-shaped robot body, a grinding mechanism, and a washing mechanism. The robot body drives the grinding mechanism to move closely against the ship's hull surface. During the grinding process, water flow is used to wash away the rust, achieving the rust removal operation.

[0004] For example, in the prior art, CN111673623A describes a rust-removing disc in a waterjet hull rust remover. The disc includes a disc body with a rust-removing chamber on its lower surface containing a nozzle. The sidewalls of the disc body are equipped with casters capable of contacting the hull. Several hinge seats are evenly distributed on the lower surface of the disc body around its centerline. A fixed shell is hinged to each hinge seat, with an elastic element between them. An arc-shaped sealing strip capable of contacting the hull is detachably installed inside the fixed shell. These arc-shaped sealing strips are concentrically arranged. This design improves the rust-removing disc's ability to overcome obstacles while ensuring rust removal sealing. However, while the aforementioned application improves the rust-removing disc to some extent, when the disc moves to the hull near the dock, the side of the dock interferes with the outer periphery of the disc. Rust removal cannot be performed on the hull at the dock's edge, requiring manual high-pressure water jetting or manual sandblasting for secondary polishing. This not only involves high labor intensity but also requires numerous pieces of equipment, resulting in high costs. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a dock bottom rust removal disc and dock bottom rust removal vehicle to improve edge adhesion, so as to solve the problem that the existing rust removal devices cannot remove rust from the bottom of the ship at the edge of the dock pier, and still require manual secondary grinding, which is labor-intensive, requires a lot of equipment, and is costly.

The cutter head is rotatably disposed in the inner cavity of the disc body, and the two end faces of the cutter head away from its own rotation axis match the inner wall of the inner cylinder. The plurality of spray holes are formed on the top surface of the cutter head. The cutter head is provided with a cutter head water inlet and a spray hole flow channel, and the cutter head water inlet and the spray hole are connected through the spray hole flow channel.

[0012] Preferably, the nozzle on the end of the cutter head away from its own axis of rotation is obliquely positioned and tilted toward the inner wall of the inner cylinder.

[0013] Preferably, the water spray assembly further includes a rotary joint, a cutter head drive source, and a rotary drive cover. The rotary joint includes a joint body and a joint housing. The end face of the joint housing is fixedly connected to the base plate. The rotary drive cover is fixedly connected to the outer peripheral surface of the joint housing. The cutter head drive source is disposed in the rotary drive cover. The joint body is rotatably disposed in the joint housing. The joint body is drively connected to the cutter head drive source. A main flow channel is formed in the joint body. The joint body penetrates the base plate and is fixedly connected to the cutter head.

[0016] As described above, the rust removal disc and rust removal vehicle for improving edge adhesion of the present invention have the following beneficial effects:

[0017] 1. In this invention, an outer extension plate is provided on the outer peripheral surface of the disc body, and the distance between the dock contact surface on the outer extension plate and the outer peripheral surface of the disc body is smaller than the distance between the non-contact surface of the dock and the outer peripheral surface of the disc body. In this way, when using high-pressure water to remove rust from the bottom of the ship, the dock contact surface of the outer extension plate can be as close to the dock as possible, and the bottom of the ship at the edge of the dock can be derusted without the need for manual hand-held high-pressure water guns or manual sandblasting for secondary grinding, thus reducing the intensity of manual labor.

The rust removal disc and rust removal vehicle for improving edge adhesion of the present invention can perform ultra-high pressure water rust removal on the bottom area of ​​the ship between two adjacent dock piers, and can also perform edge rust removal on the bottom area of ​​the ship at the edge of the dock pier. Moreover, the rust removal vehicle of this application can achieve both functions, eliminating the need for equipment for secondary manual grinding, thus reducing equipment costs.

[0029] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0030] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0031] like Figures 1-7As shown, the present invention provides a dock bottom rust removal disc for improving edge adhesion, including a disc body 1, a disc outer extension plate 2, and a water spraying assembly. The disc outer extension plate 2 is disposed on the outer peripheral surface of the disc body 1. The end face of the disc outer extension plate 2 includes a dock pier contact surface 201 and a dock pier non-contact surface 202. The distance between the dock pier contact surface 201 and the outer peripheral surface of the disc body 1 is smaller than the distance between the dock pier non-contact surface 202 and the outer peripheral surface of the disc body 1. The water spraying assembly is disposed in the inner cavity of the disc body 1 and is used to spray water to remove rust from the hull.

[0032] The present invention relates to a dock bottom rust removal disc for improving edge adhesion. An outer extension plate 2 is provided on the outer peripheral surface of the disc body 1. The end face of the outer extension plate 2 is divided into a dock pier contact surface 201 and a dock pier non-contact surface 202. The distance between the dock pier contact surface 201 and the outer peripheral surface of the disc body 1 is smaller than the distance between the dock pier non-contact surface 202 and the outer peripheral surface of the disc body 1. In this way, when the rust removal disc performs ultra-high pressure water rust removal on the bottom of the ship at the edge of the dock pier, the dock pier contact surface 201 is brought as close to the dock pier as possible, and the rust removal range of the bottom of the ship at the edge of the dock pier is expanded as much as possible. This avoids the problem of a large area of ​​the bottom of the ship at the edge of the dock pier in the prior art, which requires secondary manual grinding, resulting in high labor intensity, a large number of equipment, and high costs.

[0033] Preferred, such as Figure 1 , Figure 4 As shown, the dock contact surface 201 is a minor arc surface, and the curvature is approximately a straight line; the dock non-contact surface 202 is a major arc surface. Thus, the distance between the dock contact surface 201 and the outer peripheral surface of the disc 1 is smaller than the distance between the non-dock contact surface 201 and the outer peripheral surface of the disc 1. This allows the dock contact surface 201 to contact the dock end face, which can improve the edge adhesion of the rust removal disc and achieve rust removal on the bottom of the ship at the edge of the dock.

[0034] In this embodiment, the outer extension plate 2 of the disc is teardrop-shaped. There are two non-contact surfaces 202 of the dock, which are located at the front and rear ends of the rust removal disc (i.e., the traveling direction of the rust removal vehicle or the length extension direction of the dock). There are two contact surfaces 201 of the dock, which are located at the left and right ends of the rust removal disc (i.e., the left and right swinging direction of the rust removal disc or the width extension direction of the dock). When the rust removal disc is deflected to the left or right at a certain fixed angle, the contact surface 201 of the dock is approximately parallel to the traveling direction of the rust removal vehicle. In this way, by controlling the traveling direction of the rust removal vehicle to be parallel to the length extension direction of the dock, the contact surface 201 of the dock can be brought closer to the dock, thereby improving the edge contact of the rust removal disc.

[0035] Preferred, such as Figures 1-4As shown, the disk body 1 includes an inner cylinder 101 and a bottom plate 102. The inner cylinder 101 and the bottom plate 102 are fixedly connected. The disk body extension plate 2 is disposed on the outer circumferential surface of the inner cylinder 101. A brush buffer pad 3 is disposed on the disk body extension plate 2. The shape of the brush buffer pad 3 matches the shape of the disk body extension plate 2. A plurality of brushes 301 are disposed on the brush buffer pad 3.

[0036] In this embodiment, the base plate 102 is fixed to the bottom end of the inner cylinder 101, and the top of the inner cylinder 101 is open. The outer extension plate 2 of the disc is sleeved on the outer circumferential surface of the inner cylinder 101. To ensure the stability of the connection between the outer extension plate 2 of the disc and the inner cylinder 101, several stiffening plates 1010 are also provided between the outer extension plate 2 of the disc and the outer circumferential surface of the inner cylinder 101. An extension plate through hole is opened through the upper and lower directions of the outer extension plate 2, and a buffer pad through hole is opened on the brush buffer pad 3. The extension plate through hole and the buffer pad through hole are aligned and a locking connector is provided between them to realize the connection between the outer extension plate 2 of the disc and the brush buffer pad 3. Correspondingly, the shape of the brush buffer pad 3 is the same as that of the outer extension plate 2 of the disc, and the end face of the brush buffer pad 3 is also divided into a dock non-contact surface 202 and a dock contact surface 201.

[0037] Preferred, such as Figures 1-4 As shown, the inner cylinder 101 is a conical cylinder, and a disc connecting assembly is also provided on the outer circumferential surface of the inner cylinder 101. The disc connecting assembly is located on the lower side of the dock contact surface 201 of the outer extension plate 2 of the disc, and the disc connecting assembly is located in the axial projection area of ​​the outer extension plate 2 of the disc.

[0038] In this embodiment, the disc connecting assembly is used to install the rust removal disc on the rust removal vehicle. The inner cylinder 101 is a tapered cylinder that is wider at the top and narrower at the bottom. The disc connecting assembly is positioned below the dock contact surface 201 of the outer extension plate 2 of the disc. This provides installation space for the disc connecting assembly. At the same time, the disc connecting assembly is located within the axial projection area of ​​the outer extension plate 2 of the disc, that is, the size of the disc connecting assembly is not greater than the distance between the dock contact surface 201 and the outer circumference of the inner cylinder 101. When the rust removal disc approaches the dock, it ensures that the dock contact surface 201 of the outer extension plate 2 of the disc contacts the dock. This avoids the situation where the outer extension plate 2 of the disc cannot contact the dock after the disc connecting assembly abuts against the dock, thus preventing the rust removal and grinding of the ship bottom at the edge of the dock from occurring.

[0039] Preferred, such as Figures 1-3As shown, the disc connecting assembly includes a mounting plate 8 and a rotating shaft 9. The mounting plate 8 is fixedly disposed on the outer circumferential surface of the inner cylinder 101, and the rotating shaft 9 is fixedly disposed on the mounting plate 8. In this embodiment, there are two mounting plates 8, symmetrically disposed on the outer circumferential surfaces of the left and right ends of the inner cylinder 101. The mounting plates 8 are located below the dock contact surface 201, and the rotating shaft 9 is disposed radially outward on the mounting plate 8. The rotating shaft 9 can be hinged to the mounting arm on the rust removal vehicle to realize the pitch and deflection of the rust removal disc, which is convenient for rust removal on the sloping bottom of the ship.

[0040] Preferred, such as Figure 1 , Figure 3 , Figure 4 As shown, it also includes a drain outlet 1020 opened on the base plate 102, and a drain pipe 10 is connected to the drain outlet 1020. The drain outlet 1020 is used for drainage.

[0041] Preferred, such as Figure 1 , Figure 6 , Figure 7 As shown, the water spray assembly includes a cutter head 4 and several spray holes 401. The cutter head 4 is disposed in the inner cavity of the disc body 1, and the two end faces of the cutter head 4 away from its own rotation axis match the inner wall of the inner cylinder 101. Several spray holes 401 are formed on the top surface of the cutter head 4. The cutter head 4 has a cutter head water inlet 404 and a spray hole channel 403, and the cutter head water inlet 404 and the spray holes 401 are connected through the spray hole channel 403. In this embodiment, the cutter head water inlet 404 is formed in the middle of the bottom end face of the cutter head 4, several spray holes 401 are formed on the top surface of the cutter head 4, and the spray hole channel 403 is disposed inside the cutter head 4 to connect the spray holes 401 and the cutter head water inlet 404.

[0042] Preferred, such as Figure 1 , Figure 4 , Figure 6 As shown, the nozzle 401 on the cutter head 4, located away from its central axis, is angled and tilted towards the inner wall of the inner cylinder 101. In this embodiment, the nozzle 401 at the edge of the cutter head 4 is angled, so that the water jet from the angled nozzle 401 can be sprayed onto the bottom of the ship at the dock contact surface 201, thereby achieving rust removal and grinding of the bottom of the ship at the edge of the dock and improving the edge adhesion of the rust removal disc.

[0043] Preferred, such as Figure 1 , Figures 5-7As shown, the water spray assembly also includes a rotary joint 5, a blade drive source 7, and a rotary drive cover 6. The rotary joint 5 includes a joint body 502 and a joint housing 501. The top surface of the joint housing 501 is fixedly connected to the base plate 102, and the rotary drive cover 6 is fixedly connected to the outer peripheral surface of the joint housing 501. The blade drive source 7 is disposed in the rotary drive cover 6. The joint body 502 is rotatably disposed in the joint housing 501, and the joint body 502 is connected to the blade drive source 7. A main flow channel 5021 is provided in the joint body 502. The joint body 502 passes through the base plate 102 and is fixedly connected to the blade 4. The main flow channel 5021 communicates with the spray hole flow channel 403. A water inlet pipe is connected to the bottom port of the main flow channel 5021.

[0044] In this embodiment, the top surface of the connector housing 501 is provided with a plurality of first housing connection holes 5010, and the bottom plate 102 is provided with a bottom plate through hole and a plurality of bottom plate connection holes. The top end of the connector body 502 passes through the bottom plate through hole, and the first housing connection holes 5010 and the bottom plate connection holes are aligned, with locking connectors passing through them. The connector housing 501 is also provided with a plurality of second housing connection holes 5011, which are used to connect the rotary drive cover 6.

[0045] The top surface of the connector body 502 has several main body connection holes 5020, and the cutter head 4 has several cutter head connection holes 402 extending vertically. The cutter head connection holes 402 are aligned with the main body connection holes 5020, and locking connectors are inserted between them, thus achieving a fixed connection between the cutter head 4 and the connector body 502. When the cutter head drive source 7 drives the connector body 502 to rotate, the cutter head 4 rotates with the connector body 502. When ultra-high pressure water enters the spray channel 403 through the water inlet pipe and the main flow channel 5021, it is sprayed through the spray holes 401 on the cutter head 4 to remove rust from the bottom of the ship. To prevent the water inlet pipe from getting tangled when the connector body 502 rotates, a transition adapter is provided at the end of the water inlet pipe. The upper part of the transition adapter is rotatably mounted on the lower part of the transition adapter. The upper part of the transition adapter is connected to the port of the main flow channel 5021 of the connector body 502, and the lower part of the transition adapter is connected to the water inlet pipe.

[0046] Preferably, in this embodiment, the connector housing 501 has an inner cavity, the connector body 502 is rotatably inserted into the inner cavity, a driven wheel is provided on the outer peripheral surface of the connector body 502, the output end of the cutter head drive source 7 is connected to a driving wheel, and a transmission belt is also provided between the driving wheel and the driven wheel, the transmission belt passes through the connector housing 501 to connect the driving wheel and the driven wheel.

[0047] In this embodiment, the connector body 502 and the inner cavity of the outer shell are rotatably connected by bearings. The driven wheel is sleeved on the outer circumferential surface of the connector body 502, and the connector outer shell 501 has a transmission belt through hole for connecting the transmission belt and the driven wheel. The cutter head drive source 7 can be an electric motor or a hydraulic motor, but considering that ultra-high pressure water is introduced into the rust removal disc, electric motors are easily corroded and pose electrical hazards. Therefore, a hydraulic motor is preferred for the cutter head drive source 7.

[0048] In this embodiment, the locking connector uses a bolt, screw, or bolt and nut assembly. Further, as... Figure 3 , Figure 4 As shown, a ball bearing 11 is also provided on the top surface of the locking connector that passes between the through hole of the outer plate and the through hole of the buffer pad. The diameter of the ball bearing 11 is smaller than the height of the brush 301. In this way, the brush 301 ensures airtightness while reducing the friction between the brush buffer pad 3 and the bottom of the ship, thus ensuring the smooth movement of the dock bottom rust removal disc along the bottom of the ship.

[0049] To achieve the above or other objectives, the present invention also discloses a dock bottom rust removal vehicle, which includes the aforementioned dock bottom rust removal disc for improving edge adhesion.

[0050] The present invention relates to a dock bottom rust removal disc and dock bottom rust removal vehicle for improving edge adhesion, the working steps of which are as follows:

[0051] S1: The operator follows the instructions in the appendix. Figures 1-7 Based on the descriptions of the aforementioned components, the aforementioned components are manufactured and assembled.

[0052] S2: When the rust removal disc needs to spray water to remove rust from the bottom of the ship at the edge of the dock, the operator first adjusts the left and right swing of the rust removal disc in the horizontal direction through the control system of the rust removal vehicle, so that the rust removal disc deflects to the left or right at a certain fixed angle, and the dock contact surface 201 is parallel to the travel direction of the rust removal vehicle. Then the operator controls the rust removal vehicle to approach the dock so that the dock contact surface 201 is close to the end face of the dock, and controls the travel direction of the rust removal vehicle to be parallel to the length extension direction of the dock.

[0053] S3: After the operator moves the dock contact surface 201 close to the dock end face according to step S2, the operator starts the cutter head drive source 7 through the control system. The cutter head drive source 7 rotates and drives the joint body 502 to rotate through the drive wheel, transmission belt and driven wheel, thereby rotating the cutter head 4 on the top of the joint body 502. At the same time, ultra-high pressure water is injected into the water inlet pipe. The ultra-high pressure water enters the cutter head water inlet 404 through the main body flow channel 5021, and then is sprayed out from the spray hole 401 through the spray hole flow channel 403 to spray and remove rust from the bottom area covered by the inner cylinder 101 of the rust removal disc. The sprayed impurities and sewage are discharged from the rust removal disc through the drain outlet 1020.

[0054] S4: When the rust removal of the bottom area covered by the inner cylinder 101 of the rust removal disc is completed, the operator drives the rust removal vehicle to move along the length extension direction of the dock block through the control system to carry out rust removal of the next bottom area.

[0055] The present invention relates to a dock bottom rust removal disc and dock bottom rust removal vehicle for improving edge contact. The rust removal disc has an outer extension plate 2 on its outer peripheral surface. The end face of the outer extension plate 2 is divided into a dock pier contact surface 201 and a dock pier non-contact surface 202. The distance between the dock pier contact surface 201 and the outer peripheral surface of the disc body 1 is smaller than the distance between the dock pier non-contact surface 202 and the outer peripheral surface of the disc body 1. In this way, the dock pier contact surface 201 of the outer extension plate 2 contacts the end face of the dock pier. Compared with ordinary rust removal discs in the prior art, it can get closer to the edge of the dock pier and remove rust from the bottom of the ship at the edge of the dock pier. This effectively improves the edge contact of the rust removal disc and eliminates the need for manual hand-held high-pressure water guns or manual sandblasting for secondary grinding, thus reducing the intensity of manual labor.

[0056] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
