For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.
[0024] Example 1, by Figure 1-4It can be seen that a fastening type marine fender in this case includes a placement plate 1, which is fixedly connected to the fender 2 by bolts 3. The staff rotates the bolts 3 to fix the fender 2 to the placement plate 1, and the bottom of the fender 2 fits the surface of the placement plate 1. The staff places the fender 2 on the surface of the placement plate 1. The bottom of the placement plate 1 is fixedly connected to the cover 4. The inside of the cover 4 is provided with a fastening mechanism, which includes a handle 5, a threaded column 6, a column 7, a cross bar 8, a slide bar 9, a cross column 10 and a bolt buckle 11. The bottom of the threaded column 6 is fixedly connected to the handle 5. The staff rotates the handle 5, and the handle 5 drives the threaded column 6 to rotate. The end of the threaded column 6 is rotatably connected to the inner wall of the cover 4 through a bearing. The outer wall of the column 6 is threadedly connected with the column 7, and the threaded column 6 drives the column 7 to move. The bottom of the column 7 is fixedly connected with a cross bar 8, and the column 7 drives the cross bar 8 to move. The inner wall of the cross bar 8 is slidably clamped with a slide bar 9. The cross bars 8 on both sides slide on the slide bar 9. The two sides of the slide bar 9 are respectively fixedly connected to the inner wall of the cover body 4 and the bottom of the outer wall of the placement plate 1. The top of the column 7 is fixedly connected with a cross column 10. The column 7 drives the cross column 10 to move. The bottom of the cross column 10 is fixedly connected to a bolt buckle 11 on the side away from the column 7. The cross column 10 drives the bolt buckle 11 to descend. The inner wall of the bolt buckle 11 fits the outer wall of the bolt 3. The bolt buckle 11 clamps the bolt 3, and the bottom of the bolt buckle 11 fits the outer wall of the fender 2.
[0025] During the specific implementation process, it is worth noting that the staff rotates the bolt 3 to fix the fender 2 to the placement plate 1, and the staff places the fender 2 on the surface of the placement plate 1. The staff rotates the handle 5, and the handle 5 drives the threaded column 6 to rotate, and the threaded column 6 drives the column 7 to move, and the column 7 drives the cross bar 8 to move. The cross bars 8 on both sides slide on the slide bar 9, and the column 7 drives the cross bar 10 to move. The cross bar 10 drives the bolt buckle 11 to descend, and the bolt buckle 11 clamps the bolt 3, thereby limiting the bolt 3 and tightening the fender.
[0026] Furthermore, a sealing ring 13 is attached to the outer wall of the column 7. The outer wall of the sealing ring 13 is fixedly connected to the inner wall of the placement plate 1. When the column 7 moves, the column 7 moves in the sealing ring 13. The sealing ring 13 increases the sealing between the column 7 and the placement plate 1.
[0027] In the specific implementation process, it is worth noting that when the column 7 moves, the column 7 moves in the sealing ring 13, and the sealing ring 13 increases the sealing between the column 7 and the placement plate 1;
[0028] Furthermore, a first spring 12 is fixedly connected between the cross bar 8 and the placement plate 1. The material of the first spring 12 is carbon spring steel. The elastic coefficient of the first spring 12 is selected according to actual needs and can meet the working requirements. When the cross bar 8 moves, the cross bar 8 drives the first spring 12 to deform. At this time, the first spring 12 rebounds and further fixes the column 7 through the elastic force to prevent the threaded column 6 from rotating.
[0029] In the specific implementation process, it is worth noting that the material of the first spring 12 is carbon spring steel. The elastic coefficient of the first spring 12 is selected according to actual needs and can meet the working requirements. When the cross bar 8 moves, the cross bar 8 drives the first spring 12 to deform. At this time, the first spring 12 rebounds and further fixes the column 7 through the elastic force to prevent the threaded column 6 from rotating.
[0030] Furthermore, a mounting plate 14 is provided below the placement plate 1. Mounting holes 15 are provided on both sides of the mounting plate 14. The mounting holes 15 penetrate the mounting plate 14. There are eight mounting holes 15, which are evenly distributed on both sides of the mounting plate 14. The staff installs the fixed fender 2 onto the dock through the mounting plate 14 and the mounting holes 15.
[0031] During the specific implementation process, it is worth noting that there are 8 mounting holes 15, which are evenly distributed on both sides of the mounting plate 14. The staff installs the fixed fender 2 on the dock through the mounting plate 14 and the mounting holes 15.
[0032] When the staff member rotates the handle 5, the handle 5 drives the threaded column 6 to rotate, and the threaded column 6 drives the column 7 to move. The column 7 moves in the sealing ring 13, and the sealing ring 13 increases the sealing between the column 7 and the placement plate 1, and the column 7 drives the cross bar 8 to move. The cross bars 8 on both sides slide on the sliding rod 9, and the column 7 drives the cross bar 10 to move. The cross bar 10 drives the bolt buckle 11 to descend, and the bolt buckle 11 clamps the bolt 3 to limit the bolt 3 and tighten the fender. The cross bar 8 drives the first spring 12 to deform. At this time, the first spring 12 rebounds and further fixes the column 7 through the elastic force. After completion, the staff stops turning the handle 5. When the staff turns the handle 5 in the opposite direction, the bolt buckle 11 rises, releasing the limit of the bolt 3, and the staff installs the fixed fender 2 to the dock through the mounting plate 14 and the mounting hole 15.
[0033] Example 2, by Figure 1 and 4It can be seen that the bottom of the placement plate 1 is fixedly connected with a connecting column 16, and the placement plate 1 drives the connecting column 16 to move. The outer wall of the connecting column 16 is sleeved with a hollow column 18, and the connecting column 16 drives the hollow column 18 to slide. The bottom of the hollow column 18 is fixedly connected to the surface of the mounting plate 14, and a second spring 17 is fixedly connected between the connecting column 16 and the hollow column 18. The connecting column 16 compresses the second spring 17. During this process, the second spring 17 will rebound repeatedly, and the friction between the connecting column 16 and the rubber sleeve 19 will consume this part of the kinetic energy, play a damping role, thereby achieving a buffering effect. The material of the second spring 17 is carbon spring steel. The elastic coefficient of the second spring 17 is selected according to actual needs and can meet the work. The outer wall of the connecting column 16 is fitted with a rubber sleeve 19, and the connecting column 16 moves in the rubber sleeve 19. The outer wall of the rubber sleeve 19 is fixedly connected to the inner wall of the hollow column 18;
[0034] During the specific implementation process, it is worth noting that the material of the second spring 17 is carbon spring steel, and the elastic coefficient of the second spring 17 is selected according to actual needs and can meet the working requirements. When the ship contacts the fender 2, the ship squeezes the fender 2. At this time, the fender 2 drives the placement plate 1 to move, and the placement plate 1 drives the connecting column 16 to move. The connecting column 16 drives the hollow column 18 to slide, and the connecting column 16 moves in the rubber sleeve 19. The connecting column 16 compresses the second spring 17. During this process, the second spring 17 will rebound repeatedly, and the friction between the connecting column 16 and the rubber sleeve 19 consumes this part of the kinetic energy, plays a damping role, and thus achieves a buffering effect.
[0035] Furthermore, a cavity 20 is formed on the inner wall of the fender 2. When the fender 2 is squeezed, the cavity 20 inside the fender 2 further cushions the fender 2.
[0036] In the specific implementation process, it is worth noting that when the fender 2 is squeezed, the cavity 20 inside the fender 2 further cushions the fender 2;
[0037] Specifically, when the ship contacts the fender 2, the ship squeezes the fender 2. At this time, the fender 2 drives the placement plate 1 to move, and the placement plate 1 drives the connecting column 16 to move. The connecting column 16 drives the hollow column 18 to slide, and the connecting column 16 moves in the rubber sleeve 19. The connecting column 16 compresses the second spring 17. During this process, the second spring 17 will rebound repeatedly, and through the friction between the connecting column 16 and the rubber sleeve 19, this part of the kinetic energy is consumed, which plays a damping role, thereby achieving a buffering effect. At the same time, the cavity 20 inside the fender 2 further buffers the fender 2.
