Description
Technical Field
[0001] The utility model relates to the technical field of ship hoisting, in particular to a corner anti-wear device for ship hoisting rigging. Background Technique
[0002] Ship hoisting riggings are essential tools in the ship's cargo hoisting operations. They help the ship efficiently and safely complete tasks such as loading, unloading, and handling of goods. Ship hoisting riggings are tools made of materials such as ropes, chains, steel wires, steel cables, steel plates, etc. Their main function is to connect, fix, and support goods during the hoisting process, thereby realizing the lifting, lowering, and movement of goods. When the ropes are retracted and extended, they will rub against the corners, so a corner anti-wear device is needed.
[0003] The current corner anti-wear devices are installed at the corners through anti-wear plates or anti-wear wheels to prevent wear on the ropes. If anti-wear plates are used for anti-wear, the ropes will contact the anti-wear plates. When the ropes are retracted and extended, they will move, and the frictional resistance will not be reduced, still causing damage to the ropes. If anti-wear wheels are used to prevent wear on the ropes, the grooves on the current anti-wear wheels cannot adapt to ropes of various thicknesses. In actual applications, the grooves on the anti-wear wheels should be adapted to the thickness of the ropes to limit the ropes and prevent the ropes from swinging. If the ropes are thinner, the ropes will swing on the inner wall of the grooves of the anti-wear wheels, affecting the stability of cargo hoisting. If the ropes are thicker, it will cause the situation where the anti-wear wheels cannot limit the ropes. This problem should be solved.
[0004] Therefore, a corner anti-wear device for ship hoisting riggings is proposed. Content of the Utility Model
[0005] The purpose of the utility model is: to solve the problems mentioned in the above background technique, the utility model provides a corner anti-wear device for ship hoisting riggings.

[0023] Such as Figures 1 to 3As shown in the figure, a corner anti-wear device for a ship hoisting rigging includes a base 1 and screws 3, and there are two groups of bases 1 in total. The screws 3 are threadedly connected to the bases 1. An articulated component 2 for connecting and flipping the two groups of bases 1 is provided on the surfaces of the two groups of bases 1. A protective pad 4 for preventing the surface of the base 1 from rigidly contacting the corner is fixedly provided on the surface of the base 1. A first support plate 5 is fixedly provided on the surface of the base 1. A first limiting wheel 7 is fixedly sleeved on the surface of the first support plate 5. A second support plate 8 is movably provided on the surface of the base 1. A bushing 9 is rotatably provided on the surface of the second support plate 8. A second limiting wheel 10 is fixedly sleeved on the surface of the bushing 9, and the bushing 9 is slidably sleeved on the surface of the shaft column 6. An adjusting mechanism 11 for driving the second support plate 8 to move is provided on the surface of the base 1; specifically, the two groups of bases 1 can be flipped through the articulated component 2, so that the angles of the two groups of bases 1 are adapted to the corner. After the protective pads 4 on the two groups of bases 1 are attached to the corner, the base 1 is fixed to the corner through the screws 3. At this time, the position of the second support plate 8 is adjusted through the adjusting mechanism 11, so as to adjust the positions of the bushing 9 and the second limiting wheel 10, and further adjust the distance between the second limiting wheel 10 and the first limiting wheel 7. The distance between the second limiting wheel 10 and the first limiting wheel 7 is adjusted according to the thickness of the cable, so that the distances between the second limiting wheel 10 and the first limiting wheel 7 and the cable are adapted, thereby expanding the scope of application. The surface of the cable contacts the surface of the shaft column 6. The cable will move during the winding and unwinding process, so that the shaft column 6 rotates. Under the action of the shaft column 6, the frictional resistance between the cable and the shaft column 6 can be reduced, thereby realizing the anti-wear effect on the cable.
[0024] As Figure 1 , Figure 3 shown in the figure, the articulated component 2 includes a first fixing block 201 and a second fixing block 202. A first fixing block 201 is fixedly provided on the surface of one group of bases 1, and a second fixing block 202 is fixedly provided on the surface of the other group of bases 1. A rotating shaft 203 is rotatably provided on the surface of the second fixing block 202, and one end of the rotating shaft 203 penetrates through the surface of the second fixing block 202 and is rotatably installed on the surface of the first fixing block 201; specifically, the two groups of bases 1 are flipped so that the second fixing block 202 and the first fixing block 201 are flipped, so that the rotating shaft 203 rotates, and further the angle adjustment between the two groups of bases 1 is realized.
[0025] As Figure 1 , Figure 3 shown in the figure, there are two groups of the first fixing block 201 and the second fixing block 202, and the two groups of first fixing blocks 201 are both L-shaped; specifically, the L-shaped setting of the first fixing block 201 can make the first fixing block 201 and the second fixing block 202 be misaligned, so that the first fixing block 201 and the second fixing block 202 will not conflict with each other when flipping.
[0026] As Figure 1 , Figure 2 shown, the adjusting mechanism 11 includes a movable groove 1101. A movable groove 1101 is formed on the surface of the base 1. A threaded rod 1102 is rotatably provided on the inner wall of the movable groove 1101. One end of the threaded rod 1102 penetrates through the surface of the base 1 and extends to the outside of the movable groove 1101. A knob 1103 is fixedly provided at this end of the threaded rod 1102. A movable block 1104 is threadedly connected to the surface of the threaded rod 1102. The movable block 1104 is slidably arranged on the inner wall of the movable groove 1101. The surface of the movable block 1104 is fixedly connected to the surface of the second support plate 8. Specifically, by rotating the knob 1103, the threaded rod 1102 rotates, so that the movable block 1104 slides, and then the second support plate 8 moves. The sleeve 9 and the second limiting wheel 10 move accordingly, so as to realize the adjustment of the distance between the second limiting wheel 10 and the first limiting wheel 7.
[0027] As Figure 1 , Figure 2 shown, two groups of protective pads 4 are fixedly provided on the surfaces of the two groups of bases 1, and the two groups of protective pads 4 are arranged correspondingly. Specifically, the surfaces of the two groups of protective pads 4 are attached to the surfaces of the corners. When the cable is wound and unwound, pressure will be exerted on the surface of the shaft column 6, and then the pressure is transmitted to the protective pads 4. The protective pads 4 can prevent the surface of the base 1 from rigidly contacting the surface of the corner.
[0028] As Figure 1 , Figure 2 shown, the length of the protective pad 4 is adapted to the width of the base 1, and the protective pad 4 is made of rubber material. Specifically, after the surface of the protective pad 4 is attached to the surface of the corner, the protective pad 4 can prevent its surface from damaging the surface of the corner.
[0029] In summary: Through the hinge assembly 2, the two groups of bases 1 can be flipped, so that the angles of the two groups of bases 1 are adapted to the corners. After the protective pads 4 on the two groups of bases 1 are attached to the corners, the bases 1 are fixed to the corners by the screws 3. At this time, the position of the second support plate 8 is adjusted by the adjusting mechanism 11, so as to adjust the positions of the sleeve 9 and the second limiting wheel 10, and then adjust the distance between the second limiting wheel 10 and the first limiting wheel 7. The distance between the second limiting wheel 10 and the first limiting wheel 7 is adjusted according to the thickness of the cable, so that the distances between the second limiting wheel 10 and the first limiting wheel 7 and the cable are adapted, thereby expanding the scope of application. The surface of the cable contacts the surface of the shaft column 6. During the winding and unwinding process of the cable, the cable will move, so that the shaft column 6 rotates. Under the action of the shaft column 6, the frictional resistance between the cable and the shaft column 6 can be reduced, so as to realize the anti-wear effect on the cable.
