Description

Technical Field

[0001] The invention belongs to the technical field of laser rust removal, and in particular relates to a laser rust removal device and a rust removal method for a ship hull. Background Art

[0002] At present, the devices used for ship maintenance and rust removal operations mostly use permanent magnet crawler adsorption technology. Most of these devices have rigid crawler structures, making it difficult to achieve frequent curvature changes during movement. The adhesion surface with the hull surface is small and the adsorption force is not strong. Traditional rust removal devices mostly use high-pressure water spraying to remove rust, so there are three problems: First, when passing through the hull surface with a large curvature, the effective contact area between the crawler and the hull surface is reduced. For example, at the bow and stern, bilge and other parts with large curved surfaces, the crawler or driving wheel of the device cannot reach the minimum effective contact area required for normal operation with the hull surface, thereby reducing the adsorption force, causing the entire device to be unable to move normally, and even causing a fall accident; second, due to its relatively fixed crawler and internal structure, the equipment carried by the device cannot maintain a good working posture on the hull surface with different curvatures and large changes, affecting the quality of the operation; third, the high-pressure water spraying rust removal technology will produce flash rust during rust removal operations, and it cannot produce roughness, and there are many limitations in actual operations.

[0003] The Chinese patent with the authorization announcement number CN103934574B discloses a new type of laser rust removal device. The new type of laser rust removal device, by installing flexible longitudinal bones, enables the hull climbing laser rust removal device to achieve a large bending. When walking on the hull surface with a large curvature, the hull climbing laser rust removal device can still fit tightly and firmly adsorb on the hull surface, avoiding the device falling accident due to the reduction of adsorption area and weakening of adsorption force, effectively reducing the risk. At the same time, because the equipment mounting base is fixedly welded on the middle crossbeam, the position of the laser rust remover installed on it is relatively fixed, maintaining a good working posture. Compared with the traditional high-pressure water jet rust removal technology, laser rust removal has the advantages of no flash rust and the ability to create roughness on the hull surface.

[0004] However, the technical solution still has at least the following defects: the device only relies on a single permanent magnet track for adsorption, the adsorption capacity is limited, there is a risk of falling, and during the rust removal process, the light generated will affect the vision of the surrounding personnel. When working for a long time, the laser rust remover may overheat and cause failure. The device does not have a heat dissipation mechanism, which is inconvenient to use for a long time. The device does not have a fume treatment device and cannot adsorb the fume generated by rust removal. In view of this, the present invention is specially proposed. Summary of the invention

[0020] The present invention also discloses a laser rust removal method for a ship hull, and the steps of the laser rust removal method for a ship hull are as follows:

[0021] S1. Before use, unfold the device as a whole, slide the driving car, drive the plug rod to move through the fixed block, and make it disengage from the adapter block, continue to slide the driving car until it abuts against the mounting plate, at this time the driving car drives the block to align with the card plate, flip the driving car to keep it in the same direction as the trailer, at this time the pressure rod is disengaged from the top block, the torsion of the second torsion spring drives the pressure rod to rotate, and the pressure rod drives the block to move through the pull rod push rod, so that it is stuck with the card plate;

[0022] S2. After the driving vehicle is turned over, the slider is in a state of losing support. At this time, the torsion of the first torsion spring drives the movable door plate to rotate, and the movable door plate drives the slide plate to slide through the slide groove, thereby shielding the rust removal area of ​​the rust removal probe;

[0023] S3. When working, aim the device at the hull of the ship, and make the driving vehicle and the trailer attached to the hull through magnets. The driving vehicle is remotely controlled, and the driving vehicle drives the trailer to move on the surface of the hull. At the same time, the laser rust remover works, and the rust removal operation is performed on the hull through the rust removal probe. The light of the rust removal process is shielded by the top plate, fixed plate, slide plate, fixed door plate and movable door plate to prevent the vision of surrounding personnel from being affected;

[0024] S4. During the rust removal process, the fan works, and the smoke generated by the rust removal is absorbed by the suction force generated by the filter bin and the air inlet pipe, and then filtered through the filter net in the filter bin before being discharged, thereby reducing the pollution to the air;

[0025] S5. During the rust removal process, the motor works and drives the impeller to rotate. The impeller drives the coolant in the cooling pipe and the circulation pipe to flow. When the coolant passes through the cooling pipe, it cools down the laser rust remover and takes away the heat generated by the laser rust remover. When it flows through the circulation pipe, the wind blown by the fan dissipates the heat of the circulation pipe, thereby realizing the recycling of the coolant.

[0026] S6. After rust removal is completed, the device is folded and folded as a whole. The driving cart is flipped first. At this time, the pressure rod follows the flip and contacts the top block. The top block causes the pressure rod to rotate relative to the second torsion spring and pushes the block through the push rod. At this time, the block is disengaged from the card plate, and the driving cart is slid to reset it. The driving cart drives the push block to move through the fixed frame. The push block pulls the pull rope by resisting the slider. The pull rope drives the movable door panel to rotate and reset through the pull rod. At the same time, the movable door panel drives the slide plate to reset through the slide groove. The driving cart is reset and drives the plug rod to insert into the adapter block through the fixed block. At this time, the folding is completed.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention provides magnetic tracks on both the driving vehicle and the trailer, so that when the vehicle travels on the surface of the hull, the curvature of the surface of the quartz hull changes, and the load is increased to prevent the quartz hull from falling.

[0029] The present invention shields the laser rust removal area by setting a protective mechanism to prevent the light emitted during the rust removal process from affecting the vision of surrounding personnel;

[0030] The present invention dissipates heat for the laser rust remover by arranging a heat dissipation mechanism, thereby preventing the laser rust remover from overloading due to excessive operating temperature.

[0031] The present invention absorbs and filters the smoke generated in the rust removal process by arranging a smoke removal mechanism, and at the same time, the fan in the smoke removal mechanism can cool the cooling pipe in the heat dissipation mechanism to achieve the recycling of the coolant.

A slide groove 210 is provided on one side of the two slide plates 203 close to each other. The bottoms of both ends of the movable door plate 205 are slidably connected in the slide groove 210 through short rods.

[0056] A laser rust remover 300 is fixedly installed on the top of the trailer 101. The laser rust remover 300 is installed with a rust removal probe 301 via a cable. The rust removal probe 301 is fixedly installed on the top of the top plate 201.

[0057] A heat dissipation mechanism is provided on the top of the trailer 101, and the heat dissipation mechanism includes a cooling pipe 500, and the cooling pipe 500 is embedded in the top inner wall of the trailer 101, and the cooling pipe 500 is closely attached to the two sides and the bottom of the laser rust remover 300;

[0058] A smoke removal mechanism is provided at the bottom of the trailer 101, which includes a filter bin 401, a filter screen 402 is installed inside the filter bin 401, a fan 403 is installed at one end of the filter bin 401, and the other end of the filter bin 401 is sealedly connected to an air intake pipe 400, and the other end of the air intake pipe 400 is sealedly connected to a nearby fixed door panel 204.

[0059] like Figure 3-Figure 6As shown, in a specific embodiment, a first torsion spring 206 is installed at the connection between the movable door panel 205 and the fixed door panel 204, and both ends of the two movable door panels 205 are rotatably connected with pull rods 207.

The pull rope 208 is made of high temperature resistant material. The pull rope 208 movably passes through the top plate 201 and extends to the outside. A slider 209 is fixedly installed on the other end of the pull rope 208, and the slider 209 is slidably connected to the support plate 200.

In this setting, when the coolant passes through the cooling pipe 500, it cools down the laser rust remover 300 and takes away the heat generated by the laser rust remover 300. When flowing through the circulation pipe 502, the wind blown by the fan 403 dissipates the heat of the circulation pipe 502, thereby realizing the recycling of the coolant.

[0061] Example 2

[0062] like Figure 8-Figure 10 As shown, in a specific embodiment, the other end of the circulation pipe 502 is sealedly connected to a cabin 503, the bottom of the cabin 503 is fixedly mounted on the top of the trailer 101, a motor 506 is mounted on one side of the cabin 503, the bottom of the motor 506 is fixedly mounted on the top of the trailer 101, the shaft end of the motor 506 passes through the cabin 503, and an impeller 505 is fixedly mounted, and one end of the cabin 503 is sealedly connected to the second manifold 504.

[0063] like Figure 1 , Fig.11As shown, further, two support plates 200 are fixedly connected to each other at one end close to the driving vehicle 100, and a connecting piece 600 is rotatably connected to one end of the connection of the two support plates 200, and a fixing piece 601 is rotatably connected to one side of the connecting piece 600, and the connecting piece 600 is respectively perpendicular to the rotation axis of the support plate 200 and the fixing piece 601, and a mounting plate 602 is fixedly installed at one end of the fixing piece 601.

The top of the block 607 is rotatably connected to a push rod 608, and the top of the limit frame 605 is rotatably connected to a pressure rod 609.

In this arrangement, when unfolding, the driving vehicle 100 is slid to abut against the mounting plate 602. At this time, the driving vehicle 100 drives the stopper 607 to align with the card plate 606. The driving vehicle 100 is flipped to keep it in the same direction as the trailer 101. At this time, the pressure rod 609 is disengaged from the top block 611, and the torsion of the second torsion spring 610 drives the pressure rod 609 to rotate.

In this configuration, the driving vehicle 100 is reset and the plug rod 701 is driven to be inserted into the adapter block 702 through the fixing block 700, and the folding is completed at this time.

[0068] like Figure 4 , Figure 8 , Fig.11 As shown, further, fixed frames 703 are fixedly installed on both sides of the top of the driving vehicle 100, the cross section of the fixed frame 703 is staggered with the limit plate 604, and a push block 704 is fixedly installed on the fixed frame 703, and the push block 704 is adapted to the slider 209. In this configuration, the driving vehicle 100 drives the push block 704 to move through the fixed frame 703, and the push block 704 pulls the pull rope 208 by abutting against the slider 209.

[0069] The implementation principle of a laser rust removal device for a ship hull of this embodiment is as follows:

[0070] Before use, the device is unfolded as a whole, and the driving vehicle 100 is slid. The driving vehicle 100 drives the plugging rod 701 to move through the fixing block 700 and disengages it from the adapter block 702. The driving vehicle 100 is continued to slide until it abuts against the mounting plate 602. At this time, the driving vehicle 100 drives the stopper 607 to align with the card plate 606. The driving vehicle 100 is flipped to keep it in the same direction as the trailer. At this time, the pressure rod 609 is disengaged from the top block 611, and the torsion force of the second torsion spring 610 drives the pressure rod 609 to rotate. The pressure rod 609 drives the stopper 607 to move through the push rod 608, so as to be stuck with the card plate 606.

[0071] After the driving vehicle 100 is turned over, the slider 209 is in a state of losing support. At this time, the torsion of the first torsion spring 206 drives the movable door plate 205 to rotate, and the movable door plate 205 drives the slide plate 203 to slide through the slide groove 210, thereby shielding the rust removal area of ​​the rust removal probe 301;

[0072] When working, the device is aimed at the hull of the ship, and the driving vehicle 100 and the trailer 101 are adsorbed on the hull through the magnet 103. The driving vehicle 100 is remotely controlled, and the driving vehicle 100 drives the trailer 101 to move on the surface of the hull. At the same time, the laser rust remover 300 works, and the rust removal operation is performed on the hull through the rust removal probe 301. The light of the rust removal process is shielded by the top plate 201, the fixed plate 202, the slide plate 203, the fixed door plate 204 and the movable door plate 205 to prevent the vision of the surrounding personnel from being affected;

[0073] During the rust removal process, the fan 403 works, and the smoke generated by the rust removal is absorbed by the suction force generated by the filter chamber 401 and the air inlet pipe 400, and the smoke is filtered by the filter screen 402 in the filter chamber 401 and then discharged, thereby reducing the pollution caused to the air;

[0074] During the rust removal process, the motor 506 works and drives the impeller 505 to rotate. The impeller 505 drives the coolant in the cooling pipe 500 and the circulation pipe 502 to flow. When the coolant passes through the cooling pipe 500, it cools down the laser rust remover 300 and takes away the heat generated by the laser rust remover 300. When it flows through the circulation pipe 502, the wind blown by the fan 403 dissipates the heat of the circulation pipe 502, thereby realizing the recycling of the coolant.

[0075] After the rust removal is completed, the device is folded and folded as a whole. The driving cart 100 is flipped over first. At this time, the pressure rod 609 follows the flip and contacts the top block 611. The top block 611 causes the pressure rod 609 to rotate relative to the second torsion spring 610 and pushes the stopper 607 through the push rod 608. At this time, the stopper 607 is disengaged from the card plate 606, and the sliding driving cart 100 is reset. The driving cart 100 drives the push block 704 to move through the fixed frame 703. The push block 704 pulls the pull rope 208 by resisting the slider 209. The pull rope 208 drives the movable door panel 205 to rotate and reset through the pull rod 207. At the same time, the movable door panel 205 drives the slide plate 203 to reset through the slide groove 210. The driving cart 100 is reset and drives the insertion rod 701 to insert into the adapter block 702 through the fixed block 700. At this time, the folding is completed.

5. A laser rust removal method for a ship hull, the method being implemented based on the laser rust removal device for a ship hull according to claim 4, characterized in that: The steps of the laser rust removal method for a ship hull are as follows: S1. Before use, the entire device is unfolded and operated. The driving vehicle (100) is slid. The driving vehicle (100) drives the insertion rod (701) to move through the fixing block (700) and causes it to be separated from the adapter block (702). The driving vehicle (100) is continued to slide until it abuts against the mounting plate (602). At this time, the driving vehicle (100) drives the stopper (607) to align with the card plate (606). The driving vehicle (100) is flipped to keep it in the same direction as the trailer (101). At this time, the pressure rod (609) is separated from the top block (611). The torsion of the second torsion spring (610) drives the pressure rod (609) to rotate. The pressure rod (609) drives the stopper (607) to move through the push rod (608), thereby being mutually stuck with the card plate (606). S2, after the driving vehicle (100) is turned over, the slider (209) is in a state of losing support, at which time the torque of the first torsion spring (206) drives the movable door plate (205) to rotate, and the movable door plate (205) drives the slide plate (203) to slide through the slide groove (210), thereby shielding the rust removal area of ​​the rust removal probe (301); S3, when working, the device is aimed at the hull of the ship, and the driving vehicle (100) and the trailer (101) are adsorbed on the hull through the magnet (103), and the driving vehicle (100) is remotely controlled, and the driving vehicle (100) drives the trailer (101) to move on the surface of the hull. At the same time, the laser rust removal device (300) works, and the rust removal operation is performed on the hull through the rust removal probe (301), and the light during the rust removal process is shielded by the top plate (201), the fixed plate (202), the sliding plate (203), the fixed door plate (204) and the movable door plate (205) to prevent the eyesight of surrounding personnel from being affected; S4, during the rust removal process, the fan (403) works, and the smoke generated by the rust removal is absorbed through the suction force generated by the filter chamber (401) and the air inlet pipe (400), and the smoke is filtered through the filter screen (402) in the filter chamber (401) before being discharged, thereby reducing the pollution caused to the air; S5, during the rust removal process, the motor (506) works and drives the impeller (505) to rotate. The impeller (505) drives the coolant in the cooling pipe (500) and the circulation pipe (502) to flow. When the coolant passes through the cooling pipe (500), the laser rust remover (300) is cooled and the heat generated by the laser rust remover (300) is taken away. When the coolant flows through the circulation pipe (502), the wind blown by the fan (403) dissipates the heat of the circulation pipe (502), thereby realizing the recycling of the coolant. S6. After the rust removal is completed, the entire device is folded and folded. The driving vehicle (100) is first flipped over. At this time, the pressure rod (609) is flipped over and contacts the top block (611). The top block (611) causes the pressure rod (609) to rotate relative to the second torsion spring (610) and pushes the stopper (607) through the push rod (608). At this time, the stopper (607) is separated from the clamping plate (606). The driving vehicle (100) is slid to reset itself. The driving vehicle (100) passes through the fixed frame ( The push block (704) is driven to move by the push block (704) by resisting against the slider (209) to pull the pull rope (208), and the pull rope (208) drives the movable door panel (205) to rotate and reset through the pull rod (207), and at the same time, the movable door panel (205) drives the slide plate (203) to reset through the slide groove (210), and the driving vehicle (100) is reset and drives the insertion rod (701) to insert into the adapter block (702) through the fixed block (700), and the folding is completed at this time.
