Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding steel plate processing, in particular to a groove cutting device for FPSO steel plates. Background Art

[0002] At present, due to the harsh working environment of ships, the hull is subject to chemical corrosion, electrochemical corrosion, and corrosion by marine organisms and microorganisms from seawater; the hull is subjected to greater wind and wave impact and alternating loads; the shape of the ship makes its processing method complicated, etc., so strict requirements are placed on the steel used in the hull structure. First of all, good toughness is the most critical requirement. In addition, it is required to have higher strength, good corrosion resistance, welding performance, processing and forming performance and surface quality; Some key parts of FPSO, such as the bottom and sides of the hull, will use thicker steel plates to ensure the strength and safety of the structure. For thick steel plates, direct butt welding is very difficult because it is difficult for the welding heat to penetrate the steel plates evenly to fully fuse the entire welding interface. The V-shaped groove can gradually thin the welding section of the thick steel plate by cutting a groove with a certain angle and depth, making welding easier. For example, for a steel plate with a thickness of 30 mm, by cutting a V-shaped groove, the thickness of the steel plate at the welding point can be gradually reduced at the root of the groove, which is convenient for the welding molten pool to fully penetrate and fuse.

[0003] However, the existing cutting devices for steel plate grooves still have many shortcomings. Traditional cutting devices are mostly single-blade cutting or double-blade fixed angle settings, which are difficult to meet the complex V-shaped groove angle requirements. They are not flexible when facing FPSO steel plates of different specifications. Moreover, the distance between the cutting knives often cannot be effectively adjusted, which limits its adaptability to steel plates of different thicknesses. In addition, the large amount of smoke and dust generated during the cutting process cannot be effectively handled, seriously affecting the working environment and the health of operators.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0022] Reference Figure 1-9A bevel cutting device for FPSO steel plates comprises a bottom plate 1, a moving assembly and a clamping assembly are respectively arranged on the top side of the bottom plate 1, a fixing frame 7 is arranged on the bottom plate 1 through the moving assembly, a cylinder 8 is fixedly installed on the top side of the fixing frame 7, an output end of the cylinder 8 passes through the fixing frame 7 and is fixedly connected to a connecting plate 9, a protective cover 10 is fixedly installed on one side of the connecting plate 9, a first motor 11 is fixedly installed on one side of the connecting plate 9, an output end of the first motor 11 rotates through the connecting plate 9 and is respectively fixedly sleeved with a first pulley 12 and a first bevel gear 13, two fixing columns 14 are fixedly installed on one side of the connecting plate 9, and two fixing columns 14 are fixedly installed on one side of the connecting plate 9. The outer side of the fixed column 14 is respectively fixedly sleeved with a second pulley 15 and a third pulley 16, and one side of the connecting plate 9 is respectively fixedly installed with a first limiting column 17 and a second limiting column 18, and the outer sides of the first limiting column 17, the second limiting column 18, the first pulley 12, the second pulley 15 and the third pulley 16 share the same belt 19, and one side of the second pulley 15 and the third pulley 16 are respectively provided with an adjustment component and a cutting component, and a collection box 32 is fixedly installed on the top side of the protective cover 10, and a linkage cleaning component is provided between the collection box 32 and the first bevel gear 13, and the first limiting column 17 and the second limiting column 18 are provided. When the first motor 11 drives the first pulley 12 to rotate, under the transmission action of the belt 19, the first limiting column 17 and the second limiting column 18 are arranged to change the rotation direction of the third pulley 16, so that the second pulley 15 and the third pulley 16 synchronously drive the mounting frame 20 fixedly connected on the other side to rotate relative to each other, and when the two mounting frames 20 rotate relative to each other, the angles of the two cutting knives 28 can be adjusted, and the positions of the two cutting knives 28 can be synchronously adjusted by rotating the belt 19, and the synchronous angle adjustment of the two knives can ensure that the two cutting knives 28 change at the same rate and amplitude. The angle makes the two sides of the cut V-shaped groove completely symmetrical, and the angle error can be controlled within a very small range. This not only ensures the quality and stability of the weld, so that the weld can still maintain good mechanical properties when subjected to extreme marine environmental pressure, but also in complex marine engineering construction, this high-precision symmetrical cutting helps to reduce the repeated repair work caused by groove asymmetry, speed up construction progress and overall efficiency. At the same time, the extremely small angle error also reduces the possibility of fatigue cracks caused by welding stress concentration, greatly extending the service life of the FPSO and ensuring the long-term safety and reliability of offshore operations.

[0023] Specifically, the moving component includes two long grooves on the top side of the base plate 1, and a threaded motor 2 is fixedly installed on one side of the base plate 1.

The bottom side of the fixed frame 7 is fixedly connected to the guide block 6 and the top side of the slider 4 respectively. When the two cutting knives 28 rotate synchronously, the threaded motor 2 is started to drive the threaded rod 3 to rotate, so that the slider 4 slidably sleeved on the outer side of the threaded rod 3 synchronously drives the fixed frame 7 to move horizontally, and when the fixed frame 7 moves horizontally, the two cutting knives 28 can complete the V-shaped groove cutting of the steel plate body 45.

[0024] Specifically, the clamping assembly includes two fixing plates 42 fixedly installed on the top side of the base plate 1, and electric push rods 43 are fixedly installed on the sides of the two fixing plates 42 away from each other, and the output ends of the two electric push rods 43 pass through the fixing plates 42 and are fixedly connected to clamp plates 44, and the same steel plate body 45 is clamped between the two clamp plates 44. By providing two clamp plates 44, when it is necessary to clamp the steel plate body 45, the steel plate body 45 is placed vertically between the two clamp plates 44, and then the two electric push rods 43 are started synchronously to drive the two clamp plates 44 to move toward the two sides of the steel plate body 45, thereby achieving fixed clamping of the steel plate body 45. By fixedly clamping the steel plate body 45, positional displacement during the cutting process can be avoided, thereby reducing the need for subsequent rework due to cutting errors.

[0025] Specifically, the adjustment component includes a mounting frame 20 fixedly connected to one side of the second pulley 15 and the third pulley 16, a connecting column 21 fixedly connected to one side of the mounting frame 20, a sleeve 22 fixedly sleeved on the outer side of the connecting column 21, a curved plate 23 fixedly connected to one side of the sleeve 22, a connecting frame 24 fixedly connected to the top side of the curved plate 23, a circular hole is provided in the connecting frame 24 and the curved plate 23, a plurality of circular holes are provided with the same threaded column 25, a connecting box 26 is fixedly connected to the bottom end of the threaded column 25, a turntable 30 is fixedly connected to the top end of the threaded column 25, a threaded hole and a plurality of thread grooves are respectively provided on the top side of the turntable 30 and the connecting frame 24, a limiting rod 31 is threadedly installed in one threaded hole, the other end of the limiting rod 31 is threadedly installed in a thread groove aligned with a threaded hole, and two telescopic rods 29 are fixedly connected to the bottom side of the connecting frame 24, and the other ends of the two telescopic rods 29 are connected to the connecting box 2 The top side of 6 is fixedly connected, and two threaded columns 25 are provided. When it is necessary to adjust the distance between the two cutting knives 28, the limiting rods 31 on the two turntables 30 are removed, and then the two turntables 30 are rotated counterclockwise to drive the two connecting frames 24 to move toward the two connecting boxes 26 respectively. In the process of movement, the spacing adjustment of the cutting knives 28 can be realized, so that V-shaped groove cutting can be performed on steel plate bodies 45 of different thicknesses. After adjusting the spacing, the limiting rod 31 can be used to limit it again. The telescopic rod 29 is provided, and the telescopic rod 29 can limit the connecting frame 24 so that it can only be adjusted horizontally without rotation. In addition, the two turntables 30 are provided, and the two turntables 30 can be adjusted separately. For example, due to uneven steel plate material or temporary changes in cutting process, the operator can directly manually operate the turntable 30 for adjustment.

[0026] Specifically, the cutting assembly includes a connecting box 26 with a square hole, and a second motor 27 is fixedly installed on the inner wall of the bottom side of the square hole. The output end of the second motor 27 rotates through the connecting box 26 and is fixedly connected to a cutting knife 28. The two cutting knives 28 are symmetrically arranged. By arranging two cutting knives 28 and because the two cutting knives 28 are symmetrically arranged, after the angle adjustment is completed, starting the two second motors 27 at the same time can drive the two cutting knives 28 to rotate synchronously, so that the two cutting knives 28 can cut the steel plate body 45 in an inverted V shape.

[0027] Specifically, the linkage cleaning assembly includes a collection box 32, the bottom inner wall of which and the protective cover 10 are both provided with circular holes, the same screw rod 38 is provided in the two circular holes, the top end of the screw rod 38 is rotatably connected to the top inner wall of the collection box 32, the bottom end of the screw rod 38 is fixedly connected to a second bevel gear 39, the second bevel gear 39 is meshed with the first bevel gear 13, two guide pillars 40 are fixedly installed on the inner wall of the collection box 32, the two guide pillars 40 and the outer sides of the screw rod 38 are slidably installed with the same scraper 41, and a filter plate 3 is provided in the collection box 32. 7, one side of the scraper 41 is fitted with one side of the filter plate 37, the top side of the collection box 32 is fixedly connected with a fan 33, one side of the fan 33 is fixedly installed with a connecting pipe 34, the other end of the connecting pipe 34 is fixedly connected to the top side of the collection box 32 and communicates with the collection box 32, one side of the collection box 32 is fixedly installed with two extraction pipes 35, the other ends of the two extraction pipes 35 pass through both sides of the protective cover 10 and are fixedly connected with suction nozzles 36, the two suction nozzles 36 are symmetrically arranged and face the two cutting knives 28, and the first When the bevel gear 13 is cut on one side of the steel plate body 45 and the other side needs to be cut, the steel plate body 45 needs to be flipped. In the process of flipping the steel plate body 45, the first motor 11 runs again, which will drive the first bevel gear 13 to rotate. Because the first bevel gear 13 is meshed with the second bevel gear 39, the second bevel gear 39 will be synchronously driven to rotate while the first bevel gear 13 rotates, so that the second bevel gear 39 synchronously drives the screw rod 38 to rotate, and then the scraper 41 slidably installed on the outer side of the screw rod 38 moves up and down to clean the impurities attached to the filter plate 37, so as to avoid the impurities clogging the filter plate 37 and causing the suction effect of the suction nozzle 36 to be unsatisfactory. This situation can be avoided by providing the scraper 41 that moves up and down. In the process of the first motor 11 rotating the second bevel gear 39 through the first bevel gear 13, the angle of the two cutting knives 28 can also be changed, so that after the steel plate body 45 is flipped over, the V-shaped groove can be cut directly.

[0028] When in use: by placing the steel plate body 45 to be cut into a V-shaped groove between the two clamping plates 44, and then starting the two electric push rods 43 to drive the two clamping plates 44 to move toward the two sides of the steel plate body 45, the steel plate body 45 can be fixed, thereby preventing the steel plate body 45 from shaking during cutting. After the fixation is completed, the first motor 11 is used to drive the first pulley 12 to rotate, and because the first pulley 12, the second pulley 15, the third pulley 16, the first limiting column 17 and the second limiting column 18 share the same belt 1 9, under the transmission action of the belt 19, the first limiting column 17 and the second limiting column 18 are arranged to change the rotation direction of the third pulley 16, so that the second pulley 15 and the third pulley 16 synchronously drive the mounting frame 20 fixedly connected on the other side to rotate relatively, and when the two mounting frames 20 rotate relatively, the angles of the two cutting knives 28 can be adjusted, and the positions of the two cutting knives 28 can be synchronously adjusted by rotating the belt 19, and the synchronous angle adjustment of the two knives can ensure that the two cutting knives 28 change their angles at the same rate and amplitude, so that the cut V The two sides of the V-shaped groove are completely symmetrical, and the angle error can be controlled within a very small range, reducing the problem of subsequent rework and re-cutting. By starting the threaded motor 2 to drive the threaded rod 3 to rotate, the fixed frame 7 fixedly connected to the top side of the slider 4 moves horizontally to the right. During the horizontal movement, the two cutting knives 28 can realize the cutting of the V-shaped groove. During the horizontal movement cutting, because the steel plate body 45 is in a fixed clamping state, the cutting deviation can be avoided. While cutting the steel plate body 45, the fan 33 is started to run. The operation of the fan 33 can drive the two suction nozzles 36 to absorb the harmful gases and impurities generated by the cutting. The absorbed impurities and smoke will enter the collection box 32 along the two extraction pipes 35. The two suction nozzles 36 can be set to remove impurities and harmful gases in time to avoid the diffusion of impurities and harmful gases in the air, which not only improves the air quality in the workplace The air quality is improved, the respiratory health of the operator is protected, and it helps to keep the working area clean. In addition, the protective cover 10 is provided, which can effectively block these splashes and protect the operator from burns and eye injuries, etc. The filter plate 37 provided in the collection box 32 can prevent the impurities in the collection box 32 from being sucked into the fan 33, causing damage to the fan 33. When the other side needs to be cut after the cutting is completed, the first motor 11 is started to drive the first bevel gear 13 fixedly connected to the output end to rotate, and because the first bevel gear 13 is meshed with the second bevel gear 39, the second bevel gear 39 will be driven to rotate synchronously when the first bevel gear 13 rotates, so that the second bevel gear 39 synchronously drives the screw rod 38 to rotate, and then the scraper 41 slidably installed on the outside of the screw rod 38 moves up and down to clean the impurities attached to the filter plate 37.This can prevent impurities from clogging the filter plate 37, which would result in an unsatisfactory adsorption effect of the suction nozzle 36. The first motor 11 can also adjust the angles of the two cutting knives 28 while driving the first bevel gear 13 to rotate, so that the V-shaped groove cutting can be performed directly after the steel plate body 45 is flipped over. A box door is provided on one side of the collection box 32. After the cutting is completed, the box door can be opened to remove the impurities in the collection box 32. Then, the two electric push rods 43 can be started again to drive the two clamping plates 44 to stop clamping the steel plate body 45. Then, the cut steel plate body 45 can be removed to perform V-shaped groove cutting of the next steel plate body 45.
