Description

Technical Field

[0001] The present invention relates to the technical field of marine rotor sails, and more particularly to a rotor sail bolt fastening tooling. Background Art

[0002] The Magnus rotor sail is a huge cylindrical rotor sail installed on a ship. It can generate a pressure difference through high-speed rotation to boost the ship's forward movement. The aerodynamic principle it applies is the Magnus effect. In a stationary viscous fluid, a cylinder rotating at a constant speed will drive the surrounding fluid to move in a circular motion, and the speed of the fluid decreases as the distance from the cylinder surface increases. Therefore, the Magnus effect can be explained by the circulation flow of an inviscid incompressible fluid around a cylinder. The Magnus effect can be used to propel a ship with the help of wind power, replacing the sail with several rapidly rotating vertical cylinders. On specific routes with long-term lateral winds, during the ship's travel, the rotor sail can provide an additional thrust along the ship's travel direction during rotation, enabling the main engine to still reach the target speed while reducing the rotational speed, which will help the ship reduce energy consumption and achieve energy conservation and emission reduction.

[0003] The marine rotor sail usually consists of a steel cylinder made of fiberglass and a disk at the top. When connecting the steel cylinder and the disk, bolts need to be arranged around the end of the cylinder to pass through the disk for bolt connection, and the torque of the bolts needs to reach 650 Nm. When applying torque to the bolts, construction workers usually climb into the interior of the cylinder tower top (7.5 m above the ground) to perform the torque application operation. However, the nuts on the outside of the disk cannot be effectively fixed, and construction workers outside the disk need to use a wrench to cooperate with the workers inside the steel cylinder to apply torque. Using this conventional process to apply torque has low efficiency and high risk, and cannot ensure the safety of personnel during vertical installation operations. Secondly, due to the limitation of the disk material during the hoisting of the rotor sail, it is not convenient to install lifting lugs, resulting in inconvenience during hoisting and assembly.

[0004] In view of the above, it is necessary to propose a rotor sail bolt fastening tooling to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the above technical problems and provide a rotor sail bolt fastening tooling.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A rotor sail bolt fastening tooling includes a cylinder and a disk, and the cylinder and the disk are connected by locking bolts. It is characterized in that reinforcing plates are provided on both sides of the cylinder and the disk, and a fastening tooling is provided in cooperation with one side of the reinforcing plate.

[0007] The fastening tooling includes a clamping seat. The clamping seat consists of a flat plate and clamping plates. Clamping plates are fixedly arranged on both sides of the flat plate, making the clamping seat form a U-shaped structure. The side of the clamping seat where the clamping plates are set is the clamping opening, and the clamping seat is clamped on the reinforcing plate through the clamping opening; A through-hole structure matching with the locking bolt is penetrated through the flat plate; The clamping seat is connected and fixed to the reinforcing plate through a connecting part.

[0008] Further, the through-hole structure has a hexagonal contour hole vertically penetrating the flat plate, and the contour hole matches the specification of the nut of the locking bolt.

[0009] Further, the through-hole structure further includes a module plate. The module plate is detachably installed on the flat plate, and the contour hole is formed on the module plate; The module plate is a rectangular plate, and a rectangular hole matching with the rectangular plate is provided on the flat plate.

[0010] Further, the side length of the module plate is slightly smaller than that of the rectangular hole, so that there is a clearance gap at the edge when the module plate is placed in the rectangular hole. The clearance gap provides space for the module plate to rotate at a small angle in the rectangular hole. After the module plate rotates in the rectangular hole, filling screw holes are formed at the corners of the rectangular hole. At least filling bolts are provided in two filling screw holes at the diagonal of the rectangular hole.

[0011] Further, the clamping seat is a symmetrically separable structure passing through the through-hole structure. The middle part of the flat plate is divided into two half plates by the assembly surface. The through-hole structure includes a split ring. Two split rings are spliced to form the contour hole, and the two split rings are respectively arranged on the two half plates.

[0012] Further, ear plates are respectively arranged on both sides of the split ring. When the split rings are spliced, the ear plates on the two split rings are arranged oppositely, and an ear plate bolt is passed through the ear plates on both sides.

[0013] Further, the two half plates are spliced to form a cylindrical tube. External threads are provided on the outer wall of the cylindrical tube. The through-hole structure further includes a tightening nut, and the tightening nut is threadedly connected with the cylindrical tube.

[0014] Further, the connecting part is arranged on the clamping plates on both sides. The connecting part includes a turntable and a locking mechanism. The turntable is rotatably connected to the clamping plate, and the locking mechanism limits the rotation angle of the turntable; A long strip-shaped track is penetrated through the turntable along the diameter, a slider is arranged in the track, and a side plate bolt is screwed through the slider.

[0015] Further, the turntable is a circular disc, and an annular groove is provided on the side wall of the turntable. The annular groove has a V-shaped notch. The locking mechanism includes a caliper. A sliding cavity for the caliper to move is provided in the clamping plate. The side of the caliper facing the turntable is the jaw. A V-shaped cutting edge protruding outward is provided on the edge of the jaw, and the cutting edge is inserted into the notch to limit the turntable. The locking mechanism further includes an extrusion bolt for driving the jaw to move. The extrusion bolt is threadedly connected with the clamping plate, and the end of the extrusion bolt is rotatably connected to the side of the jaw away from the cutting edge.

[0016] Furthermore, the fastening tooling is also provided with a lifting lug, the lifting lug is vertically and fixedly arranged on the flat plate, the lifting lug is U-shaped, and both ends of the lifting lug are fixedly arranged on the flat plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Setting a reinforcing plate at the connection part of the rotor sail can increase the connection strength of the locking bolts. And through the reinforcing plate, the pressure of the locking bolts can be evenly distributed on the surface of the fiberglass material, and it is convenient to install the fastening tooling with the help of the reinforcing plate. By using the contour hole of the fastening tooling to fix one side nut of the locking bolt, it is convenient for the construction personnel to perform the torque operation on the other side of the locking nut, which can reduce the construction personnel for fixing the nut on one side and reduce the labor cost.

[0019] 2. Forming the contour hole on the module plate can facilitate the replacement of the module plate, and by setting different sizes of contour holes on the module plate, it can play a role in fixing bolts of different models, realizing the advantage of using one tooling for multiple models of bolts.

[0020] 3. Utilizing the clearance between the module plate and the rectangular hole, when the module plate is clamped in the rectangular hole by the bolt torque and cannot be taken out, removing the filling screw and using the clearance to release the extrusion pressure can facilitate the removal of the fastening tooling.

[0021] 4. Designing the card seat in an assembled form can also well avoid the problem that the nut is stuck in the contour hole and the tooling cannot be removed when the bolt torque is applied. When encountering the stuck situation, disassembling the fastening tooling can easily solve the above problem.

[0022] 5. Setting a lifting lug on the card seat can achieve the purpose of setting a temporary suspension point on the rotor sail, thus facilitating the lifting operation. Description of the Drawings

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1:

[0033] A rotor sail bolt fastening tooling includes a cylinder barrel 1 and a disc 2. As Figure 1 shown, the cylinder barrel 1 and the disc 2 are assembled to form the outer shell of the rotor sail. The cylinder barrel 1 of the rotor sail is connected to the disc 2 by a locking bolt 24. Reinforcing plates 3 are provided on both sides of the cylinder barrel 1 and the disc 2. Reinforcing plates 3 can be provided on both sides of the rotor sail where the locking bolt 24 is provided. The locking bolt 24 passes through the reinforcing plates 3 on both sides and the cylinder barrel 1 and the disc 2. The reinforcing plates 3 on both sides clamp and fix the cylinder barrel 1 and the disc 2 and can also evenly distribute the extrusion force applied by the locking bolt 24. A fastening tooling is provided in cooperation with one side of the reinforcing plate 3. As Figure 1 shown, the fastening tooling can be fixed on the outside of the disc 2;

[0034] Specifically, as Figure 2As shown in the figure, the fastening tooling includes a clamping seat 4, and the clamping seat 4 is composed of a flat plate 5 and a clamping plate 6. The clamping plates 6 are fixedly arranged on both sides of the flat plate 5, so that the clamping seat 4 forms a U-shaped structure. The side of the clamping seat 4 where the clamping plate 6 is set is the bayonet. The clamping seat 4 is clamped on the reinforcing plate 3 through the bayonet. The clamping seat 4 is connected and fixed to the reinforcing plate 3 through the connecting part 25. After the clamping seat 4 is buckled on the reinforcing plate 3, the clamping plates 6 on both sides are attached to both sides of the reinforcing plate 3, so as to prevent the flat plate 5 on the reinforcing plate 3 from rotating; a through-hole structure matching with the locking bolt 24 is arranged through the flat plate 5; by using the flat plate 5 that will not rotate to fix one end nut of the locking bolt 24, the locking bolt 24 can be torqued on the other side of the rotor sail, and on the side where the fastening tooling is set, construction workers do not need to fix the locking bolt 24, which can accelerate the torquing construction progress and is convenient for operation. When in use, the through-hole structure has a hexagonal profile hole 7 vertically penetrating the flat plate 5, and the profile hole 7 matches the nut specification of the locking bolt 24. Before the locking bolt 24 is torqued, its nut can rotate. When the clamping seat 4 is clamped on the reinforcing plate 3, the nut should be rotated so that its position is opposite to that of the profile hole 7, so that the clamping seat 4 can be clamped on the nut to fix it. The clamping plates 6 on both sides assist in limiting the flat plate 5 to prevent the flat plate 5 from being driven to rotate by the nut during torquing.

[0035] As an improvement, the profile hole 7 can be set as a round hole matching with the screw rod of the locking bolt 24. When in use, the profile hole 7 is passed through the round-hole-shaped profile hole 7, and then the nut is tightened to press the clamping seat 4. At this time, the fastening tooling can be firmly connected and fixed to the rotor sail, as Figure 1 shown. Two fastening toolings can be arranged diagonally, as Figure 2 shown. The fastening tooling is also provided with a lifting lug 23. The lifting lug 23 is vertically and fixedly arranged on the flat plate 5. The lifting lug 23 is U-shaped, and both ends of the lifting lug 23 are fixedly arranged on the flat plate 5. Such a setting can conveniently set a temporarily used lifting lug 23 on the rotor sail. The cable is passed through the lifting lug 23 and fixed, and then the rotor sail can be hoisted. After use, the fastening tooling can be conveniently removed; it can be understood that when used as a temporary lifting lug 23, at this time the profile hole 7 is a round hole, and the fastening tooling uses the locking bolt 24 to fix the whole to the rotor sail. When hoisting with the lifting lug 23, the tooling will not be pulled out when the lifting lug 23 is pulled; and when used as a tooling for torquing, at this time the profile hole 7 is a hexagonal profile hole 7 matching with the nut. At this time, the fastening tooling only has the function of restricting the rotation of the nut, and the fixing of the tooling itself is realized by the connecting part 25. At this time, the connecting part 25 can be a screw hole, and a screw is passed through the screw hole to fix the tooling to the reinforcing plate 3 together. Embodiment 2:

[0036] Since the bolt will drive the nut to rotate when applying torque, causing the nut to be stuck in the contour hole 7, it will be impossible to easily remove the fastening tooling. To solve the problem that the tooling is stuck and inconvenient to remove after tightening the bolt 24, as an improvement, as Figure 3 shown, the through-hole structure further includes a module plate 8. The module plate 8 is detachably mounted on the flat plate 5, and the contour hole 7 is formed on the module plate 8. The module plate 8 is a rectangular plate, and the flat plate 5 is provided with a rectangular hole 9 that matches the rectangular plate. In actual use, other shapes such as pentagons can also be used, which are not limited here. The advantage of using the module plate 8 is that multiple module plates 8 can be set, and each module plate 8 can be set with contour holes 7 of different sizes, so that the size of the contour hole 7 can be changed for installation and use during use, and the module plate 8 can be replaced conveniently.

[0037] Furthermore, in order to facilitate removal, the side length of the module plate 8 is slightly smaller than that of the rectangular hole 9, so that there is a clearance gap at the edge when the module plate 8 is placed in the rectangular hole 9. The clearance gap provides space for the module plate 8 to rotate at a small angle in the rectangular hole 9. After setting the clearance, the module plate 8 can rotate a certain angle clockwise or counterclockwise in the rectangular hole 9. At this time, the shape of the clearance gap changes from parallel sides to triangular sides. After the module plate 8 rotates in the rectangular hole 9, filling screw holes are formed at the corners of the rectangular hole 9. At least filling bolts 10 are provided in two filling screw holes at the diagonal corners of the rectangular hole 9. As Figure 3 shown, when actually applying torque to the locking bolt 24, the position of applying torque is at the other end of the locking bolt 24. When tightening, a counterclockwise rotational torque will be given to the module plate 8 under the drive of the nut. Since this torque is resisted by the filling bolt 10, the relative position between the module plate 8 and the flat plate 5 remains unchanged. When the torque is applied, when the nut is stuck in the contour hole 7 and cannot be removed, remove the two filling bolts 10. At this time, the clearance gap between the module plate 8 and the rectangular hole 9 comes into play and can make the module plate 8 rotate freely by a small angle, thereby releasing the pressure between the nut and the contour hole 7, so as to facilitate the separation and removal of the fastening tooling and the nut. Embodiment Three:

[0038] To facilitate the removal of the tooling after applying torque, this embodiment sets another implementation structure. The card seat 4 is a symmetrically separable structure passing through the through-hole structure. The middle part of the flat plate 5 is divided into two half plates 11 by the assembly surface. The reason why the nut and the tooling are stuck and difficult to separate is that both the contour hole 7 and the nut are integral fixed structures, resulting in difficulty in separation after being stuck. Therefore, in this embodiment, the card seat 4 is set to be separable. After tightening the torque, the tooling can be separated from the nut conveniently by disassembling the tooling. Specifically, as Figure 4As shown in the figure, the through-hole structure includes split rings 12. Two split rings 12 are spliced to form a contour hole 7. The two split rings 12 are respectively arranged on two half plates 11, which divide the original integral flat plate 5 into two symmetrical half plates 11. When the half plates 11 are joined together, they can have the overall function of the original flat plate 5. Specifically, the joining method is as follows: ear plates 13 are respectively arranged on both sides of the split ring 12. When the split rings 12 are spliced, the ear plates 13 on the two split rings 12 are arranged opposite to each other, and an ear plate bolt 14 is passed through the ear plates 13 on both sides; the two split rings 12 on both sides are formed into a complete module plate 8 through the ear plate bolt 14. Similarly, the nut can be limited when torque is applied. After the torque application is completed, the ear plate bolts 14 on both sides can be disassembled. Embodiment 4:

[0039] As an improvement to Embodiment 3, in Embodiment 3, the fixing method of the ear plates 13 on both sides is adopted. Since the nut rotates easily during torque application, which is likely to cause the two split rings 12 on both sides to separate, the fixing effect of the ear plates 13 on both sides is not good. The difference between this embodiment and Embodiment 3 is that the two half plates 11 are spliced to form a cylindrical tube, as Figure 5 shown in the figure. An external thread is provided on the outer wall of the cylindrical tube. When the two split rings 12 on both sides are spliced, a continuous external thread can be formed. The through-hole structure further includes a tightening nut 15. The tightening nut 15 is sleeved on the cylindrical tube, so that the tightening nut 15 meshes with the external thread. The wrapping and bundling fixation formed by the tightening nut 15 improves the fixing effect of the two split rings 12 on both sides, enabling the two half plates 11 to form a firm overall combination, and the strength is not lower than that of the original integral one. Embodiment 5:

[0040] As a further improvement to Embodiment 1, it can be known from Embodiment 1 that when the tooling is used as a torque tightening tooling, it needs to be fixed to the rotor sail through the connecting part 25. Due to the processing accuracy problem of the screw holes on the side of the reinforcing plate 3, the screw holes are prone to misalignment after the clamp 4 is installed. In this case, the screw cannot be screwed in smoothly, and at this time, the tightening tooling cannot be effectively fixed to the reinforcing plate 3. In addition, it can be understood from the structure of the clamp 4 that during torque application, the clamping plate 6 is mainly used to offset the rotational torque of the nut, and the connecting part 25 only plays an auxiliary fixing role, and the stress load during torque application is small; for the above reasons, this embodiment designs the screw hole processing misalignment problem as follows. Specifically, as Figure 6As shown, the connecting part 25 is arranged on the two side clamping plates 6. As shown in the figure, there are two connecting parts 25 on each of the two side clamping plates 6, and a total of four fixing points can be formed. The connecting part 25 includes a turntable 16 and a locking mechanism. The turntable 16 is rotatably connected to the clamping plate 6, and the locking mechanism limits the rotation angle of the turntable 16. A long strip-shaped track 17 is provided through the turntable 16 along the diameter. A slider 18 is arranged in the track 17, and a side plate bolt is screwed through the slider 18. Since the machining error of the side part screw holes of the reinforcing plate 3 is within a certain range, a circular range can be formed with the radius of this error range, and the screw hole range falling into the turntable 16 can be formed. Since the turntable 16 can rotate on the clamping plate 6, by using the slider 18 in the turntable 16, the slider 18 can stay at any point within the range of the turntable 16, so that the screw holes on the slider 18 can coincide with the positions of the screw holes on the reinforcing plate 3, thereby facilitating the penetration of screws to fix the position of the tooling.

[0041] Further, as Figure 6 shown, the turntable 16 is a circular disc. A ring groove 19 is provided on the side wall of the turntable 16. The ring groove 19 has a V-shaped notch. The locking mechanism includes a caliper 20. A sliding cavity for the caliper 20 to move is provided in the clamping plate 6. As Figure 7 shown, the sliding cavity can allow the caliper 20 to move closer to or away from the turntable 16. The side of the caliper 20 facing the turntable 16 is the jaw. As Figure 8 shown, a V-shaped cutting edge 21 protruding outward is provided on the edge of the jaw. The cutting edge 21 is inserted into the notch to limit the turntable 16. In actual use, the cutting edge 21 cooperates with the notch of the ring groove 19. In actual use, the angle of the cutting edge 21 can be slightly larger than the angle of the notch. In this way, when the caliper 20 moves and is clamped into the ring groove 19, the cutting edge 21 can position the turntable 16 by using the frictional force. At the same time, since the angle of the cutting edge 21 is slightly larger, an expanding effect can be formed on the notch, so that the outer walls on both sides of the notch are closely attached to the clamping plate 6 to achieve clamping. The locking mechanism further includes an extrusion bolt 22 for driving the movement of the jaw. The extrusion bolt 22 is threadedly connected to the clamping plate 6. The end of the extrusion bolt 22 is rotatably connected to the side of the jaw away from the cutting edge 21. When the extrusion bolt 22 is rotated, it can be used to drive the movement of the caliper 20.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
