[0001] The invention relates to the technical field of hull cleaning, in particular to a rust removal device for hulls used for ship maintenance. Background Art

[0002] The main purpose of ship hull rust removal is to extend the service life of the ship, ensure the safe operation of the ship and improve the strength of the hull. During the long-term immersion and operation of the hull in seawater, it will be corroded by seawater, resulting in oxidation and rust on the surface of the hull, which will not only affect the service life of the ship, but also cause damage to the hull in serious cases. Therefore, it is necessary to remove the rust of the ship in time, so a special hull rust removal device will be used.

[0003] In the prior art, the rust removal process of the hull uses a cleaning device to spray the rust remover into the surface rusted area of ​​the hull. However, since the outer side of the hull is in a sloped state, when too much rust remover is sprayed, a large amount of dripping will be produced, which is very easy to cause waste and is difficult to collect. In addition, the bottom shapes, inclinations, and bending states of different hulls are also different. Therefore, when the rust removal device is applied to the bottom of different hulls for mobile spraying, a large amount of manual control process is required to ensure that the rust removal device can fit the hull slope of any shape, which increases the difficulty of operation and the penetration efficiency of the rust remover is relatively low.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a rust removal device for ship maintenance hull, comprising a rust removal device body, the rust removal device body comprising a bottom plate 1, a fitting mechanism 4, a driving assembly 5 and a rust removal cleaning mechanism 6, the two ends of the bottom plate 1 are respectively welded with a front baffle 2 and a rear baffle 3, the interiors of the front baffle 2 and the rear baffle 3 are provided with a lifting groove 9, the bottom of the fitting mechanism 4 is embedded in the interior of the lifting groove 9, the driving assembly 5 is welded to the middle position of the surface of the bottom plate 1, and the middle sleeve of the driving assembly 5 is provided with a guide drum 25 and a traction drum 26, the surface of the guide drum 25 is wound with a guide rope 7, the surface of the traction drum 26 is wound with a traction rope 8, the bottom of the rust removal cleaning mechanism 6 is integrally formed with a support plate 15, the guide rope 7 passes through the interior of the support plate 15, the two ends of the traction rope 8 are fixedly connected to the surface of the rust removal cleaning mechanism 6, and the interior of the rust removal cleaning mechanism 6 is injected with a rust remover 22. The rust removal device for ship maintenance pulls the rust removal cleaning mechanism 6 through the driving component 5 to apply the rust remover 22 to the side of the ship hull to achieve the purpose of rust removal.

[0029] When the present invention is used, it includes an early stage of setting and planning the movement path of the rust removal and cleaning mechanism 6 and a later stage of rust removal. In the early stage, the entire rust removal device is directly pulled close to the position of the hull where rust removal is required, and is lifted with the help of two fitting mechanisms 4 until the top of the fitting mechanism 4 is pressed against two different positions on the side of the hull, and then the drive component 5 is started, and the traction rope 8 is pulled by the rotation of the drive component 5 to be tensioned. After tensioning, the linkage state between the guide drum 25 and the traction drum 26 is released by switching the locking mechanism 27, and the rust remover 22 is injected into the interior of the rust removal and cleaning mechanism 6. At this time, the drive component 5 can be started again, and the rust removal and cleaning mechanism 6 is pulled along the guide rope 7 with the help of the drive component 5 to make the rust removal and cleaning mechanism 6 move in contact with the side of the hull. In this process, the internal rust remover 22 can be applied to the side of the hull by pressing.

[0030] In this embodiment, the laminating mechanism 4 includes an electric lifting rod 10 and a laminating rod 12. The top of the electric lifting rod 10 is screwed with a lifting frame 11. The laminating rod 12 and the guide rod 13 are inserted into the inner side of the top of the lifting frame 11, and the laminating rod 12 and the guide rod 13 are kept parallel. The height of the rear baffle 3 is lower than the front baffle 2. The electric lifting rod 10 is hidden inside the lifting groove 9 as a whole, and the bottom of the lifting frame 11 is embedded in the lifting groove 9. The surface of each guide rod 13 is provided with a ring-shaped concave structure. The number of the guide ropes 7 is two, and the number of the traction rope 8 is one. One end of the guide rope 7 is fixedly connected to the surface of the guide rod 13 above the front baffle 2. The guide rope 7 passes around the surface of the guide rod 13 above the rear baffle 3. The traction rope 8 passes around the surfaces of the guide rods 13 above the front baffle 2 and the rear baffle 3 at the same time. The moving path of the rust removal and cleaning mechanism 6 can be planned and restricted in advance by using the driving component 5 at the bottom in conjunction with the two ropes, so that the subsequent rust removal process can be automatically completed through the driving component 5, and it can ensure that the rust removal and cleaning mechanism 6 moves along the planned rust removal path, so that it can be suitable for use on hulls of different shapes. The entire process does not require manual operation and has a wide range of applications.

[0031] Specifically, by starting the electric lifting rods 10 at both ends, the lifting frame 11 can be lifted upward along the inside of the lifting slot 9, and finally the fitting rod 12 on the top of the lifting frame 11 can be pressed against the side of the hull. At this time, the traction rope 8 can be guided and supported by the guide rod 13 on the fitting mechanism 4. After the guide rope 7 is subsequently tensioned by the driving assembly 5, the rust removal and cleaning mechanism 6 mounted on the surface can be pressed against the side of the hull with the help of the two guide ropes 7. When the rust removal and cleaning mechanism 6 is subsequently controlled to move along the guide rope 7, the process of fitting and coating can be maintained on the surface of the hull with any inclination and bending state.

[0032] In this embodiment, the rust removal cleaning mechanism 6 includes a rust removal box 14 and a sponge roller 18. A central axis 21 is inserted into the inner wall of the rust removal box 14. The sponge roller 18 is sleeved on the surface of the central axis 21, and the bottom of the sponge roller 18 is immersed in the rust remover 22. A spring rod 20 is inserted into the side of the rust removal box 14, and a pressing rod 19 is inserted into the top of the spring rod 20. Threading holes 16 are opened at the edges of both sides of the support plate 15, and a hanging ring 17 is welded in the middle of both sides of the support plate 15. Both ends of the traction rope 8 are connected to the hanging ring 17. Since the upward pressure provided to the rust removal cleaning mechanism 6 by the guide telescopic always ensures that the rust remover 22 is fully coated on the surface of the hull, and when dripping occurs, the dripping rust remover 22 is collected nearby and directly reused, so that the rust remover 22 can be fully coated and effectively collected, the utilization rate is improved, and the coating of the rust remover 22 is more uniform and effective.

[0033] Specifically, after the guide rope 7 passes through the threading hole 16, the support plate 15 and the rust removal box 14 can be pressed against the side of the hull, and the internal sponge roller 18 can be pressed against the surface of the hull. When the traction rope 8 is pulled and reeled in by the driving component 5, the entire rust removal and cleaning mechanism 6 can be pulled to move along the guide rope 7, and during the movement, the rust remover 22 at the bottom is adsorbed and squeezed onto the surface of the hull by the sponge roller 18 pressing on the surface of the hull and rolling. At the same time, the pressing rods 19 on both sides are also pushed upward by the spring rods 20 at the bottom to ensure that the pressing rods 19 can be pressed on the rusted area of ​​the hull at the same time, so as to ensure that the entire rust removal and cleaning mechanism 6 can move smoothly.

[0034] In this embodiment, the driving assembly 5 includes a motor 24, a guide reel 25 and a traction reel 26. A second plug hole 30 is provided on the inner side of one end of the guide reel 25. A plurality of first plug posts 31 are welded on the outer side of one end of the guide reel 25. First plug holes 29 are provided on the outer sides of both ends of the traction reel 26. An end plate 23 is welded on the surface of the bottom plate 1. The outer shell of the motor 24 is fixed to the surface of one of the end plates 23 with screws. A drive shaft 28 is inserted at the output end of the motor 24. The drive shaft 28 passes through the inside of each guide reel 25 and the traction reel 26 in turn. The drive shaft 28 and the traction reel 26 are welded as a whole. The drive shaft 28 and the guide reel 25 are separated. By switching the locking mechanism 27 on the driving component 5, it is possible to control whether the guide reel 25 and the traction reel 26 are linked. Therefore, the early process of demarcating the rust removal area and the subsequent rust removal process of the device can be completed by only a single power device, which reduces the equipment cost. The entire rust removal process can also ensure that the rust removal cleaning mechanism 6 always maintains a high fitting pressure, so that the rust remover 22 penetrates more thoroughly.

[0035] Specifically, after starting the motor 24, the traction drum 26 is driven to rotate by the driving shaft 28, so that the traction rope 8 wound on the surface can be wound and unwound. In the early stage of tensioning the guide rope 7, the guide drum 25 and the traction drum 26 are connected and linked by switching the locking mechanism 27. At this time, the guide drum 25 and the traction drum 26 rotate synchronously, so that the guide rope 7 can also be wound at the same time. After the connection between the guide drum 25 and the traction drum 26 is released by switching the locking mechanism 27, only the traction drum 26 can be controlled to rotate by the rotation control of the motor 24. At this time, the guide drum 25 is connected to the switching locking mechanism 27 and no longer rotates. Therefore, only the traction rope 8 can be controlled to pull the rust removal cleaning mechanism 6 to move along the tensioned guide rope 7 to realize the rust removal process.

[0036] In this embodiment, the switching locking mechanism 27 includes a screw rod 33 and a clamping plate 34. The front end of the screw rod 33 is integrally formed with a hand wheel 32. The end of the screw rod 33 is sleeved with a docking bearing 35. The docking bearing 35 is embedded in one end of the clamping plate 34. A second plug-in column 36 is welded to the inner end of the clamping plate 34. The first plug-in column 31 is used to be embedded in the first plug-in hole 29, and the second plug-in column 36 is used to be embedded in the second plug-in hole 30. A threaded hole is opened on the top of the end plate 23. The screw rod 33 passes through the threaded hole on the end plate 23, and the clamping plate 34 is clamped at the edge of the guide reel 25. Specifically, by turning the hand wheel 32, the screw rod 33 rotates to cooperate with the docking bearing 35 to push the clamping plate 34 forward, and the guide reel 25 can be pushed toward the rear end until the first plug-in column 31 is embedded in the first plug-in hole 29. At this time, the guide reel 25 and the traction reel 26 can maintain a linked state, or by turning the hand wheel 32, the clamping plate 34 pulls the guide reel 25 toward the end, and the second plug-in column 36 on the clamping plate 34 can be embedded in the second plug-in hole 30, thereby releasing the linkage state between the guide reel 25 and the traction reel 26, and the guide reel 25 and the switching locking mechanism 27 can be docked.
