Technical Field
[0001] The utility model relates to the field of hoisting, in particular to a marine hook group. Background Technique
[0002] The marine hook group is an important device used for cargo handling operations on ships. It consists of multiple components such as hooks, chains, slings, pulleys, etc., and can withstand the huge load during offshore operations. The marine hook group is usually installed on cranes or lifting equipment on ships, and grabs and transports goods through the hook part of the hook, realizing the lifting and transfer of ship cargo.
[0003] When unloading goods on a ship, the crane places the hook group at the position where unloading is required through the control system. The hook body part of the hook will firmly hook the sling or cable on the goods. Subsequently, the crane starts the lifting operation, slowly raises the goods from the cabin, and moves the goods to the ship's side or loading and unloading area. During the lifting process, the cable on the goods may fall off. Therefore, an anti-dropping device is usually installed on the hook. The existing anti-dropping device is generally a device with a spring installed on the inner surface of the hook. By blocking the cable from slipping out of the hook opening, the anti-dropping function is realized.
[0004] However, this anti-dropping component on the hook can only operate when the hook hooks a little cable. When there are multiple groups of cables on the hook of the hook group and the diameter of the cable is large, the cable squeezes the anti-dropping component against the inner wall of the hook, resulting in the anti-dropping component being unable to reset to block the cable, making it difficult for the anti-dropping component on the hook group to operate. Content of the Utility Model
[0005] Based on this, the purpose of the utility model is to provide a marine hook group to solve the technical problem that the anti-dropping device is difficult to operate when the traditional anti-dropping hook hooks multiple groups of ropes.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A marine hook group includes a pulley frame. A hook handle is arranged at the bottom of the pulley frame, and a hook body is fixedly connected to the bottom of the hook handle. A limiting block is fixed to the outer wall of the hook body. Two limiting rods are slidably installed inside the limiting block. One end of the limiting rod is provided with a blocking block, and one side of the blocking block is attached to the end of the hook body. One side of the limiting rod is connected with a connecting block, and the two limiting rods are connected through the connecting block. A second fixing ring is arranged on one side of the connecting block, and a spring is installed inside the second fixing ring.
[0007] By adopting the above technical solution, an arc-shaped limiting rod is provided at the opening of the hook body. A blocking block is fixed at one end of the limiting rod, and the blocking block is in close contact with the head of the hook body. The limiting rod and the blocking block cooperate with each other to limit the cable on the hook body, preventing the cable from detaching from the hook body. In addition, a limiting block is fixed on the outer wall of the top end of the hook body, and the limiting rod passes through the inside of the limiting block, enabling the limiting rod to slide inside the limiting block.
[0008] The present utility model is further configured such that the limiting rod is arc-shaped, and the limiting rod and the hook body form a closed state.
[0009] By adopting the above technical solution, when no thrust is applied to the blocking block by a person, since the spring contracts and tightens the connecting block, the blocking block fixed at the end of the limiting rod closely fits the hook body. The hook body is circular, and the limiting rod is arc-shaped, and the two form a closed ring to limit the cable on the hook body and prevent it from falling off.
[0010] The present utility model is further configured such that a first fixing ring is provided on one side of the hook handle, and the first fixing ring is connected to one end of the spring.
[0011] By adopting the above technical solution, the spring is fixedly connected to the outer wall of the hook handle through the first fixing ring, so that the spring connected to the first fixing ring takes the hook handle as a fixed point and contracts and tightens the second fixing ring at the other end of the spring.
[0012] The present utility model is further configured such that a rotating rod is provided on the outer wall of the hook handle, and the hook handle is movably connected to the pulley frame through the rotating rod.
[0013] By adopting the above technical solution, when the object hooked by the hook body is too heavy, it may shake during the hoisting process. Since the hook handle and the pulley frame are movably connected through the rotating rod, when the hook body shakes and drives the hook handle to shake together, the shaking amplitude of the pulley frame will be relatively small, reducing the risk of instability of the hook group caused by the swinging of the object.
[0014] The present utility model is further configured such that a plurality of groups of pulleys are installed inside the pulley frame, and the pulleys are movably connected to the pulley frame.
[0015] By adopting the above technical solution, a plurality of groups of pulleys are installed inside the pulley frame, and the hook cable of the hook group is wound around the pulleys. By increasing the number of cable strands wound around the pulleys, the output end of the hook cable shares the force received on the hook body.
[0016] In summary, the present utility model mainly has the following beneficial effects:
[0017] 1. The utility model solves the problem that it is difficult for the anti - detachment device to operate when multiple ropes are hooked by a traditional anti - detachment hook by setting a limit block, a limit rod and a blocking block. By setting an arc - shaped limit rod at the opening of the hook body, one end of the limit rod is fixed with a blocking block, and the blocking block is in close contact with the head of the hook body. The limit rod and the blocking block cooperate to limit the cable on the hook body, preventing the cable from detaching from the hook body. In addition, a limit block is fixed on the outer wall of the top end of the hook body, and the limit rod passes through the inside of the limit block, enabling the limit rod to slide inside the limit block;
[0018] 2. The utility model sets a first fixing ring, a spring, a second fixing ring and a connecting block. A second fixing ring is arranged on the connecting block fixed at one end of the limit rod. The second fixing ring is connected to the spring, and at the same time, the other end of the spring is connected to the first fixing ring arranged on the hook handle. The spring tightens the first fixing ring and the second fixing ring connected at both ends, pushing the connecting block to move the limit rod, so that the blocking block connected to one end of the limit rod is closely attached to the head of the hook body, preventing the cable from slipping off the hook body due to the slack of the limit rod.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.
[0024] The embodiments of the present utility model will be described below according to its overall structure.
[0025] A marine hook group, as Figure 1 - Figure 3As shown in the figure, it includes a pulley frame 3. A hook handle 12 is provided at the bottom of the pulley frame 3, and a hook body 1 is fixedly connected to the bottom of the hook handle 12. A limiting block 4 is fixed to the outer wall of the hook body 1. Two groups of limiting rods 5 are slidably installed inside the limiting block 4. One end of the limiting rod 5 is provided with a blocking block 6, and one side of the blocking block 6 is in contact with the end of the hook body 1. One side of the limiting rod 5 is connected to a connecting block 11, and the two groups of limiting rods 5 are connected by the connecting block 11. A second fixing ring 10 is provided on one side of the connecting block 11, and a spring 9 is installed inside the second fixing ring 10. By providing an arc-shaped limiting rod 5 at the opening of the hook body 1, a blocking block 6 is fixed at one end of the limiting rod 5, and the blocking block 6 is in close contact with the head of the hook body 1. The limiting rod 5 and the blocking block 6 cooperate with each other to limit the cable hooked on the hook body 1 and prevent the cable from detaching from the hook body 1. In addition, a limiting block 4 is fixed to the outer wall at the top of the hook body 1, and the limiting rod 5 penetrates through the inside of the limiting block 4, enabling the limiting rod 5 to slide inside the limiting block 4.
[0026] Please refer to Figure 3 , the limiting rod 5 is set to be arc-shaped, and the limiting rod 5 and the hook body 1 form a closed state. When no thrust is applied to the blocking block 6 by a person, since the spring 9 contracts and tightens the connecting block 11, the blocking block 6 fixed to the end of the limiting rod 5 is in close contact with the hook body 1. The hook body 1 is circular, and the limiting rod 5 is set to be arc-shaped, and the two form a closed ring to limit the cable hooked on the hook body 1 and prevent it from falling off.
[0027] Please refer to Figure 3 , a first fixing ring 8 is provided on one side of the hook handle 12, and the first fixing ring 8 is connected to one end of the spring 9. The spring 9 is fixedly connected to the outer wall of the hook handle 1 through the first fixing ring 8, so that the spring 9 connected to the first fixing ring 8 takes the hook handle 1 as a fixed point and contracts and tightens the second fixing ring 10 at the other end of the spring 9.
[0028] Please refer to Figure 2 , a rotating rod 7 is provided on the outer wall of the hook handle 1, and the hook handle 1 is movably connected to the pulley frame 3 through the rotating rod 7. When the object hooked by the hook body 1 is too heavy, it may shake during the hoisting process. Since the hook handle 1 and the pulley frame 3 are movably connected through the rotating rod 7, when the hook body 1 shakes and drives the hook handle 1 to shake together, the shaking amplitude of the pulley frame 3 will be relatively small, reducing the risk of the hook group being unstable due to the swinging of the object.
[0029] Please refer to Figure 1 and Figure 2Multiple groups of pulleys 2 are installed inside the pulley frame 3, and the pulleys 2 are movably connected to the pulley frame 3. Multiple groups of pulleys 2 are installed inside the pulley frame 3, and the hook cables of the hook group are wound around the pulleys 2. By increasing the number of cable strands wound around the pulley 2, the output end of the hook cable shares the force on the hook body 1.
[0030] The working principle of the utility model is as follows: first, a person moves the blocking block 6 toward the inner side of the hook body 1, and the limiting rod 5 fixed at one end of the blocking block 6 slides toward the inside of the hook body 1 through the limiting block 4, and at the same time, the connecting block 11 stretches the spring 9 through the second fixing ring 10. When the person moves the blocking block 6 to contact the inner surface of the hook body 1, the cable to be hooked is put on the hook body 1, and then the blocking block 6 is released. Since the other end of the spring 9 is connected to the first fixing ring 8 fixed on the surface of the rotating rod 7, the spring 9 tightens and contracts the second fixing ring 10 on the connecting block 11, so that the connecting block 11 is reset, and at the same time, the blocking block 6 returns to the starting position and is in close contact with the head of the hook body 1, and the limiting rod 5 limits the cable on the hook body 1 to prevent the cable from detaching from the hook body 1.
