Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of shot blasting machine technology, and more specifically, to a shot blasting device for the bottom of a ship. Background Technology

[0002] Bottom shot blasting is an important part of ship maintenance. In the marine environment, a rust layer will form on the bottom of the ship, and the anti-rust coating on the bottom will peel off and fail after prolonged immersion. Many marine organisms will also stubbornly adhere to the bottom of the ship. Bottom shot blasting uses the rapid rotation of the impeller to launch fine metal shots quickly through centrifugal force. The metal shots collide with the bottom of the ship, destroying the marine organisms, rust layer and anti-rust paint on the bottom under the impact, causing them to separate from the bottom of the ship. At the same time, the impact of the metal shots makes the bottom surface rough, and the coating adhesion will be better after repainting.

[0003] The existing method of shot blasting the bottom of ships involves moving the shot blasting machine by a mobile vehicle. The shot blasting direction of the machine is upward, and the shot blasting nozzle is in contact with the bottom of the ship. After shot blasting, the metal shot is simultaneously recovered. Currently, the position of the shot blasting nozzle is controlled manually by the operator during operation. Since the bottom of the ship has curved surfaces with different curvatures, problems such as poor contact of the shot blasting nozzle leading to sand leakage, excessive pressure increasing the resistance of the vehicle, and increasing the difficulty of operation are prone to occur. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a ship bottom shot blasting device to solve the technical problem in the prior art that the shot blasting nozzle is not tightly attached to the ship bottom when performing shot blasting cleaning on the ship bottom.

[0005] According to one aspect, at least one embodiment of this disclosure provides a ship bottom shot blasting device, including a ship bottom shot blasting cart, a deflection base, a lifting platform, a sealing and bonding mechanism, a deflection detection mechanism, and a dual-head drive cylinder. The deflection base is fixedly mounted on the ship bottom shot blasting cart, and the lifting platform is rotatably connected to the deflection base. A shot blasting mechanism is slidably connected to the lifting platform. The shot blasting mechanism is provided with a shot blasting port and a recovery port, both of which are located above the shot blasting mechanism. The shot blasting mechanism is used to clean the ship bottom by shot blasting and to seal and bond the ship bottom. The sealing and fitting mechanism is installed on the shot blasting port. During shot blasting, the sealing and fitting mechanism is in contact with the bottom of the ship. The sealing and fitting mechanism is used to fit with the bottom of the ship during shot blasting. There are two deflection detection mechanisms. The two deflection detection mechanisms are rotatably connected to both sides of the shot blasting port. The double-head drive cylinder is installed below the shot blasting port. The two output ends of the double-head drive cylinder are rotatably connected to the two deflection detection mechanisms. The double-head drive cylinder can push the two deflection detection mechanisms to the side of the sealing and fitting mechanism.

[0006] The lifting platform is provided with a guide rail, a lifting slider and a drive cylinder. The guide rail is fixedly connected to the lifting platform, the lifting slider is slidably connected to the guide rail, a frame is fixedly connected to the lifting slider, the shot blasting mechanism is set on the frame, and the drive cylinder is fixedly installed on the lifting slider. The output end of the drive cylinder is fixedly connected to the lifting platform.

[0007] The shot blasting mechanism includes guide rods, a fixed frame, and shot blasting equipment. Multiple guide rods are fixedly connected to the frame, and shock-absorbing springs are fitted onto each guide rod. The fixed frame is slidably connected to the multiple guide rods. The shot blasting equipment is fixedly installed in the fixed frame and has a shot blasting channel through which metal shot moves. The shot blasting nozzle is located at the end of the shot blasting channel away from the shot blasting equipment, and the nozzle opening faces upwards.

[0008] The sealing and bonding mechanism includes a second guide rail, a bonding port assembly, a first slide cylinder, a first slide rod, and a first pressure sensor. Multiple second guide rails are provided, and these are fixedly connected to the side of the shot blasting port. The bonding port assembly is slidably connected to the second guide rail and can be aligned with the shot blasting port. The bonding port assembly contacts the bottom of the ship and is used to seal the shot blasting port with the bottom of the ship during bottom cleaning. The first slide cylinder is fixedly connected to the shot blasting port, and the first slide rod is fixedly connected to the bonding port assembly. The first slide rod is slidably connected to the first slide cylinder. The first pressure sensor is fixedly installed in the first slide cylinder at the end away from the bonding port assembly, and a spring is provided between the first pressure sensor and the first slide rod.

[0009] The fitting assembly includes a mouth-shaped frame, a docking frame, J-shaped spring sheets, and a closing frame. Multiple sliding rods are fixedly connected to the mouth-shaped frame, and the second guide rail is slidably connected to the sliding rods. The docking frame is fixedly connected inside the mouth-shaped frame and can be inserted into the shot blasting port. Multiple J-shaped spring sheets are provided and fixedly connected to the mouth-shaped frame. The multiple J-shaped spring sheets are arranged around the mouth-shaped frame, with one end of each J-shaped spring sheet away from the mouth-shaped frame curved, and the curvature direction facing the outer edge of the mouth-shaped frame. The closing frame is fixedly connected to the mouth-shaped frame and is sleeved on the outside of the multiple J-shaped spring sheets.

[0010] The retractable frame and the J-shaped spring sheet are configured with an annular cavity, and an annular airbag is provided in the annular cavity. The annular airbag is sleeved on the outside of the plurality of J-shaped spring sheets.

[0011] Multiple sealing teeth are provided on the side of the gathering frame away from the shot blasting port. The sealing teeth are aligned with the gap between the adjacent J-shaped spring sheets. When the J-shaped spring sheets are bent and in contact with the gathering frame, the sealing teeth and the J-shaped spring sheets are staggered.

[0012] The deflection detection mechanism includes a flip frame, a sliding seat, a second sliding cylinder, a second sliding rod, a second pressure sensor, and a roller. The flip frame is rotatably mounted on the shot blasting channel, and the sliding seat is slidably mounted on the flip frame. The sliding seat is rotatably connected to the output end of the dual-head drive cylinder. The second sliding cylinder is fixedly connected to the sliding seat, and the second sliding rod is slidably connected in the second sliding cylinder. The second pressure sensor is fixedly installed in the second sliding cylinder, and a spring is provided between the second pressure sensor and the second sliding rod. The roller is rotatably mounted on one end of the second sliding rod that extends out of the second sliding cylinder.

[0013] When the output ends on both sides of the dual-head drive cylinder are extended, both sliding seats rotate to the side of the blasting frame. At this time, the roller is on the side of the blasting frame away from the shot blasting nozzle.

[0014] The beneficial effects of the embodiments disclosed herein are as follows:

[0015] 1. In this invention, by setting a deflection base and a lifting platform, the angle and height of the shot blasting equipment can be adjusted, avoiding the problem that the shot blasting nozzle is difficult to truly fit with the bottom of the ship due to different angles at different positions, resulting in different degrees of tightness at different positions and causing sand to escape.

[0016] 2. In this invention, by setting a double-headed drive cylinder, two deflection detection mechanisms are driven to measure the angle between the shot blasting port and the bottom of the ship on both sides of the shot blasting port, thereby adjusting the angle of the shot blasting port and avoiding different pressures between the two sides of the sealing and bonding mechanism and the bottom of the ship.

[0017] 3. In this invention, by setting a sealing and bonding mechanism, the shape of the bonding part can be changed according to the different curvatures of the ship bottom, thereby achieving a tight fit. By setting a deflection detection mechanism, the angle of the tight fit mechanism can be adjusted, thereby making the shot blasting angle more accurate. At the same time, the fit between the sealing and bonding mechanism and the ship bottom is more uniform and less prone to sand leakage. Compared with the prior art, the sealing and bonding mechanism can achieve a tight fit at various positions on the ship bottom. At the same time, the detection by the deflection detection mechanism eliminates the need for human eye to judge the rotation angle, improving the accuracy of the shot blasting nozzle angle.

[0028] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0029] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0030] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-8The diagram illustrates a ship bottom shot blasting device according to an embodiment of this disclosure, comprising a ship bottom shot blasting cart 1, a deflection base 2, a lifting platform 3, a sealing and fitting mechanism, a deflection detection mechanism, and a double-headed drive cylinder 6. The deflection base 2 is fixedly mounted on the ship bottom shot blasting cart 1, and the lifting platform 3 is rotatably connected to the deflection base 2. A shot blasting mechanism is slidably connected to the lifting platform 3. The shot blasting mechanism is provided with a shot blasting port 4 and a recovery port 5, both located above the shot blasting mechanism. The shot blasting mechanism is used to clean the ship bottom through shot blasting. The sealing and fitting mechanism is located on the shot blasting port 4 and is in contact with the ship bottom during shot blasting. The sealing and fitting mechanism is used to maintain contact with the ship bottom during shot blasting. The deflection detection mechanism is... There are two deflection detection mechanisms, which are rotatably connected to both sides of the shot blasting port 4. The double-head drive cylinder 6 is located below the shot blasting port 4. The two output ends of the double-head drive cylinder 6 are rotatably connected to the two deflection detection mechanisms. The double-head drive cylinder 6 can push the two deflection detection mechanisms to rotate to the side of the sealing and bonding mechanism. When contacting the bottom of the ship, the deflection detection mechanism first contacts the bottom of the ship to determine whether the angle of the sealing and bonding mechanism is aligned with the cleaning position of the bottom of the ship. Since it is necessary to align the shot blasting mechanism with the bottom of the ship to ensure a good cleaning effect and reduce sand runoff, the angle is adjusted before bonding with the bottom of the ship. At the same time, the pressure sensor 17 and pressure sensor 29 determine whether there is a tight fit with the bottom of the ship and adjust the height accordingly.

[0035] like Figures 1-4 As shown, the lifting platform 3 is equipped with a guide rail 7, a lifting slider 8, and a drive cylinder 9. The guide rail 7 is fixedly connected to the lifting platform 3, and the lifting slider 8 is slidably connected to the guide rail 7. A frame 31 is fixedly connected to the lifting slider 8, and the shot blasting mechanism is set on the frame 31. The drive cylinder 9 is fixedly installed on the lifting slider 8, and the output end of the drive cylinder 9 is fixedly connected to the lifting platform 3. The distance between the shot blasting port 4 and the bottom of the ship is adjusted by the drive cylinder 9 driving the lifting slider 8 to slide on the guide rail 7. The movement of the drive cylinder 9 is fed back by the pressure sensor 17. By adjusting the height of the movement of the lifting slider 8 driven by the drive cylinder 9, the tightness of the contact with the shovel body is adjusted. At the same time, the angle between the shot blasting port 4 and the bottom of the ship is changed by the rotation of the lifting platform 3 driven by the deflection base 2.

[0036] like Figures 1-4As shown, the shot blasting mechanism includes guide rods 10, a fixed frame 11, and a shot blasting device 12. Multiple guide rods 10 are fixedly connected to the frame 31, and shock-absorbing springs are fitted onto each guide rod 10. The fixed frame 11 is slidably connected to the multiple guide rods 10. The shot blasting device 12 is fixedly installed in the fixed frame 11 and has a shot blasting channel 13 through which metal shot moves. A shot blasting port 4 is located at the end of the shot blasting channel 13 furthest from the shot blasting device 12. With the opening facing upwards, the shot blasting equipment 12 sprays metal shot through the shot blasting channel 13 into the shot blasting port 4. After being ejected through the shot blasting port 4, the metal shot contacts the bottom of the ship. The fixed frame 11 slides on the guide rod 10, while simultaneously compressing the shock-absorbing spring. The shock-absorbing spring can reduce the vibration experienced by the shot blasting equipment 12 during the movement of the shot blasting car 1 on the bottom of the ship. At the same time, when the drive cylinder 9 pushes the contact port assembly to make contact with the transmission, it can buffer the impact and prevent the output end of the drive cylinder 9 from being pulled too fast, which would cause the contact port assembly to be squeezed and damaged.

[0037] like Figures 2-6 As shown, the sealing and bonding mechanism includes a second guide rail 14, a bonding assembly, a first slide cylinder 15, a first slide rod 16, and a first pressure sensor 17. Multiple second guide rails 14 are provided, and these multiple guide rails 14 are fixedly connected to the side of the shot blasting port 4. The bonding assembly is slidably connected to the second guide rail 14 and can be aligned with the shot blasting port 4. The bonding assembly contacts the bottom of the ship and is used to seal the shot blasting port 4 with the bottom of the ship during bottom cleaning. The first slide cylinder 15 is fixedly connected to the shot blasting port 4, and the first slide rod 16 is fixedly connected to the bonding assembly. The first slide rod 16 is slidably connected to the first slide cylinder 15. Force sensor 17 is fixedly installed in the slide cylinder 15 at the end away from the fitting assembly. A spring is provided between pressure sensor 17 and slide rod 16. After the fitting assembly contacts the bottom of the boat, slide rod 16 slides into slide cylinder 15 and compresses the spring. Pressure sensor 17 detects the pressure of the spring. By judging the pressure change, the sliding distance of the fitting assembly and the pressure it receives in contact with the bottom of the boat can be detected. A pressure sensor is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to a certain rule.

[0038] like Figures 5-6As shown, the fitting assembly includes a mouth-shaped frame 18, a docking frame 20, J-shaped spring plates 21, and a closing frame 22. Multiple sliding rods 19 are fixedly connected to the mouth-shaped frame 18, and a guide rail 14 is slidably connected to the sliding rods 19. The docking frame 20 is fixedly connected inside the mouth-shaped frame 18 and can be inserted into the shot blasting port 4. Multiple J-shaped spring plates 21 are provided and fixedly connected to the mouth-shaped frame 18. The multiple J-shaped spring plates 21 are arranged around the mouth-shaped frame 18, with the end of the J-shaped spring plate 21 away from the mouth-shaped frame 18 being curved, and the curvature pointing towards the outer edge of the mouth-shaped frame 18. The closing frame 22 is fixedly connected to the mouth-shaped frame 18. Above, the gathering frame 22 is fitted over the outside of multiple J-shaped spring sheets 21. When the J-shaped spring sheets 21 come into contact with the bottom of the ship, the spring in the slide cylinder 15 is first squeezed. The pressure on the J-shaped spring sheets 21 can be determined by detecting the pressure detected by the pressure sensor 17. When the docking frame 20 extends into the shot blasting port 4, and the mouth frame 18 connects with the shot blasting port 4, the slide cylinder 1 and the slide rod 28 stop sliding relative to each other. The arc-shaped parts on the multiple J-shaped spring sheets 21 bend during the compression with the bottom of the ship, so that the multiple J-shaped spring sheets 21 bend at different angles according to the different curvatures of different positions on the bottom of the ship, and thus fit the shape of the bottom of the ship.

[0039] like Figure 6 As shown, an annular cavity 32 is set between the retractable frame 22 and the J-shaped spring sheet 21. An annular airbag 23 is set in the annular cavity 32. The annular airbag 23 is sleeved on the outside of multiple J-shaped spring sheets 21. Multiple sealing teeth 24 are set on the side of the retractable frame 22 away from the shot blasting port 4. The sealing teeth 24 are aligned with the gap between the adjacent J-shaped spring sheets 21. When the J-shaped spring sheet 21 is bent and contacts the retractable frame 22, the sealing teeth 24 and the J-shaped spring sheet 21 are staggered. When the J-shaped spring sheet 21 fits the shape of the hull bottom... At this time, the J-type spring plate 21 compresses the annular airbag 23. The annular airbag 23 supports the J-type spring plate 21 on the one hand and fills the gap between the J-type spring plates 21 on the other hand, thereby achieving a tighter seal. When the J-type spring plate 21 contacts the retractable frame 22, the sealing teeth 24 can also seal. At the same time, since the contact position between the J-type spring plate 21 and the bottom of the ship is an arc-shaped part, when the bottom shot blasting car 1 performs shot blasting cleaning during movement, the arc-shaped part on the J-type spring plate 21 can also slide on the bottom of the ship.

[0040] like Figures 6-8As shown, the deflection detection mechanism includes a flip frame 25, a sliding seat 26, a second sliding cylinder 27, a second sliding rod 28, a second pressure sensor 29, and a roller 30. The flip frame 25 is rotatably mounted on the shot blasting channel 13, and the sliding seat 26 is slidably mounted on the flip frame 25. The sliding seat 26 is rotatably connected to the output end of the dual-head drive cylinder 6. The second sliding cylinder 27 is fixedly connected to the sliding seat 26, and the second sliding rod 28 is slidably connected in the second sliding cylinder 27. The second pressure sensor 29 is fixedly installed in the second sliding cylinder 27, and a spring is provided between the second pressure sensor 29 and the second sliding rod 28. The roller 30 is rotatably mounted on the end of the second sliding rod 28 that extends out of the second sliding cylinder 27. When both output ends of the dual-head drive cylinder 6 are extended, both sliding seats 26 rotate to the side of the mouth frame 18. At this time, the roller 30 is on the side of the mouth frame 18 away from the shot blasting port 4. Before the J-type spring plate 21 contacts the bottom of the ship, the two output ends of the double-headed drive cylinder 6 extend to push the sliding seat 26 to slide on the flip frame 25. At the same time, the flip frame 25 is pushed to rotate on the shot blasting channel 13, which drives the slide rod 28 and the roller 30 to rotate. When the roller 30 contacts the bottom of the ship, the slide rod 28 compresses the spring, causing the pressure sensor 29 to detect the pressure. Only when the pressure detected by the pressure sensor 29 in the two slide cylinders 27 on both sides is equal, and the shot blasting port 4 is parallel to the tangent of the bottom of the ship, the output end of the double-headed drive cylinder 6 shortens to pull the sliding seat 26 to slide on the flip frame 25 and drive the flip frame 25 to rotate, so that the roller 30 separates from the bottom of the ship. When the lifting platform 3 drives the shot blasting equipment 12 to rotate, the roller 30 rolls while in contact with the bottom of the ship, making the angle adjustment easier.

[0041] Based on the feedback from pressure sensor 17 and pressure sensor 29, the extension and retraction of the output end of the drive cylinder 9 can be controlled by the PLC system, thereby controlling the orifice frame 18 to maintain a certain pressure on the bottom of the boat, but the pressure will not be too high.

[0042] In some examples, the bottom shot blasting vehicle 1 moves the shot blasting equipment 12 to the bottom of the ship. The two output ends of the double-headed drive cylinder 6 extend and push the sliding seat to slide on the tilting frame 25. At the same time, the tilting frame 25 rotates, causing the slide rod 28 to tilt up, so that the roller 30 contacts the bottom of the ship. The slide rod 28 compresses the spring in the slide cylinder 27. The deflection base 2 drives the lifting platform 3 to rotate, adjusting the angle of the shot blasting equipment 12. At the same time, the rollers 30 on both sides of the shot blasting equipment 12 roll on the bottom of the ship, and the slide rod 28 slides in the slide cylinder 27. When the pressure sensor 29 on both sides of the shot blasting port 4 detects... When the measured pressure is the same, the two output ends of the double-headed drive cylinder 6 shorten and pull the sliding seat to slide on the flip frame 25. At this time, the output end of the drive cylinder 9 shortens and pulls the lifting slider 8 to slide upward on the guide rail 7. The J-type spring plate 21 contacts the bottom of the ship, the sliding rod 19 slides in the guide rail 14, the sliding rod 16 squeezes the spring in the sliding cylinder 15, the pressure sensor 17 detects the pressure, the docking frame 20 extends into the shot blasting port 4, the J-type spring plate 21 bends as the bottom of the ship is squeezed, the airbag squeezes the J-type spring plate 21 and fills the gap between the J-type spring plates 21.
