Two locking screw buckles 18 are fixedly provided at the hull 1 positions at both ends of the rubber pad 11. The rubber pad 11 is located below the tire 12. When the hull 1 is pressed against When the hull 1 is touched, the tire 12 will be touched first. A cable 15 is fixed at the end of a lock turn buckle 18, and the cable 15 is in contact with the side of all tires 12 away from the hull 1. A plurality of second rolling belts 16 are wound around the cable 15, and both ends of each second rolling belt 16 pass through the middle of the tire 12. A plurality of eye plates 17 are fixed at the front end of the hull 1, and both ends of the plurality of second rolling belts 16 are fixedly connected to different eye plates 17. The first rolling belt 14 and the second rolling belt 16 are distributed in the middle of each tire 12 in a cross shape, and the eye plates 17 are symmetrically distributed on the upper surface and the front end of the hull 1 in the horizontal and vertical directions.

[0026] First, the first rolling belt 14 is passed horizontally through the connecting hole 13 on the tire 12. The two ends of the first rolling belt 14 are respectively connected to the positioning components on the hull 1. The first rolling belt 14 is located on the outer side of the tire 12, and has a certain angle with the inner side of the tire 12, which is used to limit the tire 12 to prevent the tire 12 from moving left and right. The tires 12 are installed at the bow position on the hull 1 through the first rolling belt 14 in turn, and then the cable 15 is horizontally attached to the surface of the tire 12. The second rolling belt 16 is wrapped around the center of each tire 12. On the cable 15 in position, both ends of the second rolling belt 16 pass through the middle of the tire 12, and the two ends are connected to the eye plate 17 respectively. The second rolling belt 16 pulls the cable 15 toward the tire 12, so that the cable 15 fits tightly with the tire 12. Through the second rolling belt 16, the cables 15 are now located in the middle of the tire 12, and all tires 12 are connected together through the cable 15 to increase the stability of the tire 12. The first rolling belt 14 and the second rolling belt 16 are distributed in the tire 12 in a cross shape to prevent the tire 12 from flipping over and the rolling belt from breaking.

[0027] In the specific implementation process, Figure 2 and Figure 3 As shown, the positioning assembly includes a plurality of fixed blocks 2 fixedly connected to the hull 1, a fixed column 21 is fixedly provided in the middle of the fixed block 2, a movable column 22 is slidably provided in the fixed column 21, an arc rod 23 is fixedly provided at one end of the movable column 22, mounting blocks 24 are fixedly provided at both ends of the arc rod 23, and the mounting blocks 24 are connected to the ends of the first rolling belt 14; the mounting blocks 24 at both ends of the arc rod 23 can connect two first rolling belts 14, and the ends of the first rolling belts 14 are tied to the round shafts in the mounting blocks 24, so that the first rolling belts 14 are in a taut state, and the first rolling belt 14 drives the tire 12 to fit tightly against the outer wall of the bow of the hull 1.

[0028] In the specific implementation process, Figure 3 and Figure 6As shown, a rotating frame 3 is rotatably provided on the outer wall of the fixed block 2, and a connecting rod 31 is rotatably provided on the outer wall of the rotating frame 3. One end of the connecting rod 31 is rotatably connected to the moving column 22. A plurality of positioning blocks 32 for squeezing the mounting block 24 are fixedly provided on the hull 1. Limiting grooves 4 are provided on the upper and lower sides of the fixed column 21. Limiting blocks 41 are fixedly provided on both sides of the outer wall of the end of the moving column 22. Both limiting blocks 41 pass through the limiting grooves 4. Both ends of the two opposite positioning blocks 32 are provided with inclined surfaces 5. By pressing down the rotating frame 3, the rotating frame 3 rotates along the fixed block 2, the rotating frame 3 drives the connecting rod 31 to move, and the end of the connecting rod 31 pulls the moving column 22 to move into the fixed column 21. The limiting blocks 41 on the moving column 22 slide along the limiting grooves 4. The moving direction of the movable column 22 is limited, and the limit block 41 prevents the movable column 22 from separating from the fixed column 21. The movable column 22 drives the arc rod 23 to move synchronously. The mounting blocks 24 at both ends of the arc rod 23 enter the positioning block 32 along the inclined surface 5 on the positioning block 32. The positioning block 32 squeezes the plates at the front ends of both sides of the mounting block 24 toward the middle, and the plates squeeze the first rolling strip 14. Since the circular shaft is located at the rear end inside the mounting block 24, the squeezing of the plates at the front end of the mounting block 24 will not cause problems with the connection position of the circular shaft. Since the first rolling strip 14 is in direct contact with the tire 12, the shaking of the tire 12 will drive the first rolling strip 14 to shake, thereby preventing the first rolling strip 14 from shaking and separating from the mounting block 24, thereby improving the stability of the first rolling strip 14.

By rotating the bolts on the lock turn buckle 18, the cable 15 can be tightened to improve the stability of all tires 12.

[0030] Specifically, the working principle and operation method of the present invention are as follows:

[0031] First, the first rolling belt 14 is passed horizontally through the connecting hole 13 on the tire 12, and the two ends of the first rolling belt 14 are respectively tied to the round shaft in the mounting block 24, and the rotating frame 3 is pressed down, and the rotating frame 3 rotates along the fixed block 2, and the rotating frame 3 drives the connecting rod 31 to move, and the end of the connecting rod 31 pulls the moving column 22 to move into the fixed column 21, and the limiting block 41 on the moving column 22 slides along the limiting groove 4 to limit the moving direction of the moving column 22, and the moving column 22 drives the arc rod 23 to move synchronously, and the mounting blocks 24 at both ends of the arc rod 23 enter the positioning blocks 32 along the inclined surface 5 on the positioning blocks 32, and the positioning blocks 32 squeeze the plates at the front ends of both sides of the mounting blocks 24 toward the middle, and the plates squeeze the first rolling belt 14, and the tire 12 is prevented from moving left and right through the first rolling belt 14, and then the tire 12 is installed at the bow position on the hull 1 through the first rolling belt 14 in sequence;

[0032] Then, the cable 15 is horizontally attached to the surface of the tire 12, and the two ends of the cable 15 are connected together by a locking turn buckle 18, and the cable 15 can be tightened by turning the bolt on the locking turn buckle 18;

[0033] Finally, the second rolling belt 16 is wrapped around the cable 15 at the center of each tire 12. Both ends of the second rolling belt 16 pass through the middle of the tire 12 and are respectively connected to the eye plate 17. The second rolling belt 16 pulls the cable 15 toward the tire 12 so that the cable 15 fits tightly against the tire 12. All tires 12 are connected together through the cable 15 to increase the stability of the tire 12.
