Description

Technical Field

[0001] This invention relates to a hoisting rope hook anti-detachment device and method, belonging to the field of hoisting technology. Background Technology

[0002] In construction, material handling, and other fields, hooks are essential lifting devices in hoisting machinery. Traditional hooks typically have an open structure and are connected to the object via ropes or rigging.

[0003] In the unloading process of traditional hoisting rope hooks, a crane is usually used to lift the item and move it to the vicinity of the worker, then the item is lowered to the ground, and the hook is then manually separated from the rope. In the current object hoisting process, the object may fall abnormally due to the complex external environment. At this time, the manual receiving method is quite dangerous.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a hoisting rope hook anti-disengagement device and method, which solves the problem that in the unloading process of traditional hoisting rope hooks, it is usually necessary to use a crane to lift the object and move it to the vicinity of the worker, then lower the object to the ground, and then manually operate to separate the hook from the rope. In the existing object hoisting process, the object may fall abnormally due to the complex external environment. At this time, the manual receiving method is too dangerous.

[0006] The technical problem to be solved by the present invention is achieved by the following technical solution: a hoisting rope hook anti-disengagement device, comprising two fixed locking blocks, fixed components provided on the two fixed locking blocks, mounting grooves provided on the fixed locking blocks, a positioning shaft rotatably connected between the inner walls of opposite sides of the mounting groove, a hook body fixedly connected on the positioning shaft, a hook block one fixedly connected to one end of the hook body, and a hook block two provided at the other end of the hook body; The inner wall of the hook body is provided with a sliding groove, and a push block is slidably connected in the sliding groove. Both ends of the push block are fixedly connected with vertical blocks, and the vertical blocks are slidably connected to the sliding groove. The hook body is equipped with an anti-disengagement mechanism, which can drive hook block two to abut against hook block one; A rod is fixedly connected between the two fixed locking blocks. A limiting mechanism is provided on the rod. A rope is provided on the hook body. The limiting mechanism can limit the rope. The fixed locking block is equipped with a rotating component that can drive the hook body to rotate.

[0007] The present invention is further configured such that: the anti-disengagement mechanism also includes a positioning groove formed on the hook body, a return spring is fixedly connected to the inner wall of the groove, one end of the return spring near the push block is fixedly connected to the inner wall of the bottom groove, and a limiting groove is formed on the inner walls of the opposite sides of the groove, and two limiting blocks are fixedly connected to the push block, and the limiting blocks are slidably connected to the limiting groove.

[0008] The present invention is further configured such that: the anti-disengagement mechanism includes two rotating seats fixedly connected to the hook body, the hook block two is rotatably connected between the two rotating seats, the hook block two is provided with a rotating groove, a rotating block is provided in the rotating groove, one end of the rotating block is rotatably connected between the inner walls of opposite sides of the rotating groove, and the other end of the rotating block is rotatably connected to a push block, the push block is fixedly connected to a vertical block.

[0009] The invention is further configured such that: the anti-disengagement mechanism also includes a positioning groove formed on the hook body; a fixing groove 1 is formed on the side of hook block 1 near hook block 2; the fixing groove 1 communicates with the positioning groove; hook block 3 is slidably connected in the fixing groove 1; the vertical cross-sections of hook block 2, hook block 1, and hook block 3 are all crescent-shaped; the tip of hook block 1 abuts against the inner wall of the hook body; a limiting block is fixedly connected to the side of hook block 3 away from hook block 2; the limiting block is slidably connected to the positioning groove; multiple positioning springs are fixedly connected to the side of the limiting block away from hook block 3; the end of the positioning spring away from the limiting block is fixedly connected to the inner wall of the positioning groove; hook block 3 can abut against hook block 2; a wire rope is fixedly connected to the side of the limiting block away from hook block 3; a slide is formed on the hook body; the end of the wire rope away from the limiting block is fixedly connected to the vertical block through the slide.

[0010] The present invention is further configured such that: the anti-disengagement mechanism also includes a limiting groove, the limiting groove is formed through the hook body, and a horizontal sliding rod is fixedly connected to the limiting block, the horizontal sliding rod being inserted into the limiting groove.

[0011] By adopting the above technical solution, in the initial state, under the support of the return spring, the push block extends to the outside of the slide groove towards one side of the vertical block. At this time, hook block two does not contact hook block one, and the upper surface of the vertical block abuts against the top wall of the slide groove. In the initial state, the positioning spring is in a slightly compressed state, and then under the action of the release force of the positioning spring, hook block three abuts against hook block two, and pushes hook block three to give hook block two a certain pushing force, so that hook block three and hook block two abut against each other more tightly. When the rope buckle is inserted into the hook body, it can be pushed through the contact point between the rope buckle and hook block three and the hook body. During the insertion process, the rope buckle pushes hook block three upward, thereby causing hook block three and the limiting block to move upward. During this process, the positioning spring is compressed, causing it to deform further. When the rope buckle passes between hook block three and hook block two, the release force of the positioning spring causes hook block three to return to the contact state with hook block two. The contact state between hook block three and hook block two has a certain limiting effect on the rope buckle hooked onto the hook body, so that the rope buckle cannot easily come off the hook body when it is not under force. This prevents the rope buckle from easily separating from the hook body before the item is lifted, thereby improving the safety of the anti-disengagement device for the hoisting rope hook. When an item is lifted, its own weight exerts a downward pull on the push block, causing it to move downwards. This push block compresses the return spring, causing it to deform. The downward movement of the push block simultaneously moves the rotating block downwards, which in turn pulls the rotating block, causing hook block two to rotate around the hinge between the rotating seat and hook block two. This rotation moves hook block two closer to hook block one until they come into contact. The weight of the item then seals the opening of the hook body, preventing the rope from detaching from the hook body during lifting. This further enhances safety, simplifies operation, and improves the overall safety of the anti-detachment device for lifting rope hooks.

[0012] The present invention is further configured such that: the fixing component includes a bolt rod, and multiple fixing holes are provided through both fixing blocks; the bolt rod passes through the fixing holes and the fixing blocks; a fixing nut is threaded onto the bolt rod; a sliding hole is provided through the fixing blocks; a positioning lifting block is fixedly connected to the fixing blocks; and a sliding hole is provided through the positioning lifting block.

[0013] By adopting the above technical solution, the bolt rod passes through the fixing holes on the two fixing blocks and then the fixing nuts are tightened, which enables the two fixing blocks to abut and fix them. During disassembly, the fixing nuts can be removed directly, and then the bolt rod can be removed, so that the individual fixing blocks can be replaced. This facilitates the individual replacement and maintenance of the two fixing blocks and the hook body.

[0014] The invention is further configured such that: the rotating component includes a motor, the motor is fixedly mounted on a fixed locking block, a support groove is provided on the top wall of the mounting groove, a threaded rod is rotatably connected between the inner walls of opposite sides of the support groove, one end of the threaded rod is poweredly connected to the output end of the motor, a connecting block is threadedly connected to the threaded rod, a slide rail groove is provided on the connecting block, a sliding block is slidably connected in the slide rail groove, a fixed seat is fixedly connected to the hook body, and one end of the sliding block extends out of the outer side of the connecting block and is hinged to the fixed seat.

[0015] By adopting the above technical solution, in the initial state, the hook body is in a vertical position. At this time, a rope buckle can be attached to the hook body to lift and transfer the item. When it is necessary to lower the item to the ground and disengage the hook body from the rope buckle, the item must first be lowered to the ground so that the rope is no longer under the tension of the item. Because the rope is no longer under the tension of the item, hook block two returns to the state of contact with hook block three. Then, the motor is started, causing the motor to drive the hook body to rotate away from the pole. When the hook body rotates to an angle of about 100 degrees (the threshold of the rotation angle is usually between 95 degrees and 120 degrees, preferably 100 degrees, within this angle threshold, the opening of the hook body faces...), (And facilitates the rope buckle to slide out). At this time, hook block three and hook block two are facing downwards. When the crane moves the hook body upwards, the rope buckle is stretched and straightened, and the rope buckle will slide out of the hook body between hook block three and hook block two, thus completing the disassembly of the rope buckle. During the disassembly of the rope buckle, it is not necessary for the operator to manually remove the rope buckle by holding the hook body. The entire hoisting process, except for the initial hoisting operation, does not require manual intervention in the subsequent transportation process. There is also no need for manual receiving of goods in the receiving step. Therefore, it avoids the situation where the goods fall abnormally during the hoisting process and injure the personnel. It saves manpower and is safer, thereby improving the practicality and safety of the hoisting rope hook anti-disengagement device.

[0016] In this solution, each fixed locking block is equipped with a hook body. By setting two fixed locking blocks, after the two fixed locking blocks are fixed by the fixing components, two kinds of materials can be simultaneously suspended on two hook bodies. The crane can then lift and transfer the two items at the same time. When one item needs to be unloaded, both items can be lowered to the ground first. Then, the corresponding motors are started to drive the corresponding hook bodies to rotate to the disassembled state. Then, the crane is started to move both hook bodies upwards simultaneously. At this time, the hook body that remains vertical will safely lift the item again. Meanwhile, the hook body that remains disassembled will detach from the hooked rope during the upward movement, thus completing the separate unloading of the items. The operation is simple, more flexible, and saves manpower, thereby improving the flexibility and convenience of the lifting rope hook anti-detachment device.

[0017] The invention is further configured such that: the limiting mechanism includes a sliding cylinder, which is slidably sleeved on the insert rod; multiple connecting springs are fixedly connected to the bottom wall of the sliding cylinder; the upper ends of the connecting springs are fixedly connected to the insert rod; a positioning hole is opened through the insert rod; a rubber ring is fixedly connected inside the positioning hole; a connecting hole is opened through the sliding cylinder; a push plate is provided on the lower side of the sliding cylinder; multiple adjusting screw holes are opened through the push plate; a fixing bolt is threaded into the adjusting screw hole; the end of the fixing bolt can be threadedly connected to the bottom of the sliding cylinder; a movable sliding rod is fixedly connected to the lower end of the push block; a movable groove is opened on the lower surface of the hook body; the lower end of the movable sliding rod slides through into the movable groove and is fixedly connected to a movable block; the movable block is slidably connected to the movable groove.

[0018] The present invention is further configured such that: the limiting mechanism also includes two fixed arc plates, which are respectively fixedly connected to the top walls of the two connecting holes, and rubber arc blocks are fixedly connected inside the fixed arc plates.

[0019] By adopting the above technical solution, when the item is long or heavy, the rope can be passed through the two hook bodies, the connecting hole and the rubber ring, as shown in the attached figure. At this time, the two hook bodies can jointly bear the weight of the item. While sharing the weight, due to the horizontal distance between the two lifting points, the parallel part of the lifting rope is spaced out. At this time, the parallel lifting rope with a large gap is less likely to twist and entangle, making the stability of the item during transportation higher. Simultaneously, when the item is lifted, its own weight causes the push block to move downwards. During this downward movement, the push block rotates the second hook block, which then engages with the first hook block to prevent detachment. The downward movement of the push block also simultaneously moves the sliding rod downwards, which in turn moves the moving block downwards. As the moving block moves downwards, it engages with the push plate and pushes the push plate downwards. The downward movement of the push plate then simultaneously moves the sliding cylinder downwards, which in turn moves the fixed arc plate and the rubber arc block downwards. This causes the rope to be compressed between the bottom wall of the rubber ring and the top wall of the rubber arc block. Because both the rubber ring and the rubber arc block are made of rubber, their compression of the rope restricts and fixes it. The friction generated by this compression prevents the rope from sliding along its extension direction during lifting, thus preventing the item from swaying. This improves the stability of the item during lifting and further enhances the safety and stability of the anti-detachment device for the lifting rope hook.

[0020] A method for preventing the hook from detaching from a hoisting rope hook, the method comprising: S1. Secure the two locking blocks with the fixing assembly, and then fix the two locking blocks to the lifting equipment; S2. Hook the rope buckle used for hoisting the goods into the hook body; S3. Start the rotating assembly to rotate the hook body to a vertical position, and start the lifting equipment to lift the item; S4. After the item is hoisted to the designated location and lands, the rope buckle is no longer under tension, and the rotating component is activated to rotate the hook body so that the hook body opening faces downward. S5. Restart the lifting equipment to move the hook body upward, and the rope buckle slides out between hook block three and hook block two to complete the unloading.

[0021] The beneficial effects of this invention are as follows: the rotating component can drive the hook body to rotate away from the insertion rod. When the hook body rotates at an angle of about 100 degrees, the hook body is in an inclined state, with hook block three and hook block two facing downwards. When the crane drives the hook body upwards, the rope buckle is stretched and straightened, and the rope buckle will disengage from the hook body between hook block three and hook block two, thereby completing the disassembly of the rope buckle. During the disassembly of the rope buckle, it is not necessary for a person to manually hold the hook body to remove the rope buckle. The entire hoisting process, except for the initial hoisting operation, does not require manual intervention in the subsequent transportation process. There is also no need for manual receiving of goods in the receiving step. Therefore, it avoids the situation where the goods fall abnormally during the hoisting process and injure the personnel. It saves manpower and is safer, thereby improving the practicality and safety of the anti-disengagement device for the hoisting rope hook. Attached Figure Description

[0024] To facilitate a clear understanding of the technical means, inventive features, objectives, and effects of this invention, the following detailed description is provided. Figures 1 to 8 The invention will be further illustrated as shown.

[0025] like Figures 1 to 5 As shown, the present invention is a hoisting rope hook anti-disengagement device including two fixed locking blocks 1. The two fixed locking blocks 1 are provided with fixing components, which can fix the two fixed locking blocks 1. The fixed locking blocks 1 are provided with mounting grooves 11, which extend through the left and right sides of the fixed locking blocks 1. The inner walls of the opposite sides of the mounting grooves 11 are rotatably connected to a positioning shaft 8. A hook body 7 is fixedly connected to the positioning shaft 8. The hook body 7 is C-shaped. One end of the opening of the C-shape of the hook body 7 is fixedly connected to a hook block 1 9, and the other end of the opening of the C-shape of the hook body 7 is provided with a hook block 2 17. The inner wall of the hook body 7 is provided with a sliding groove 18. A push block 22 is slidably connected in the sliding groove 18. The push block 22 extends into the hook body 7 through the sliding groove 18. Vertical blocks 19 are fixedly connected to both ends of the push block 22. The vertical cross section of the combination of the vertical block 19 and the push block 22 is U-shaped. The vertical block 19 is located in the sliding groove 18 and is slidably connected to the sliding groove 18. The vertical cross section of the sliding groove 18 is U-shaped. The hook body 7 is equipped with an anti-disengagement mechanism, which can drive hook block 2 17 to abut against hook block 1 9. A rod 32 is fixedly connected between two fixed locking blocks 1 by bolts. A limiting mechanism is provided on the rod 32. A rope 39 is provided on the hook body 7. The rope 39 passes through the limiting mechanism, and the limiting mechanism can limit the rope 39. The fixed locking block 1 is equipped with a rotating component that can drive the hook body 7 to rotate.

[0026] In this scheme, each fixed locking block 1 is equipped with a hook body 7.

[0027] like Figures 1 to 5 As shown, the anti-disengagement mechanism includes a bottom groove 36 formed on the lower surface of the push block 22. A return spring 40 is fixedly connected to the inner wall of the slide groove 18. One end of the return spring 40 near the push block 22 extends into the bottom groove 36 and is fixedly connected to the inner wall of the bottom groove 36. The extension and retraction path of the return spring 40 is consistent with the movement path of the push block 20. Restriction grooves 37 are formed on the inner walls of opposite sides of the slide groove 18. Two restriction blocks 38 are fixedly connected to the push block 22. The restriction blocks 38 are slidably connected to the restriction grooves 37.

[0028] like Figures 1 to 5 As shown, the anti-disengagement mechanism also includes two rotating seats 10 fixedly connected to the hook body 7. The rotating seats 10 are located at the end of the hook body 7 away from the hook block 9. The hook block 17 is rotatably connected between the two rotating seats 10. The hook block 17 is provided with a rotating groove 30. A rotating block 31 is provided in the rotating groove 30. One end of the rotating block 31 is rotatably connected between the inner walls of the opposite sides of the rotating groove 30. The other end of the rotating block 31 extends out of the outer side of the hook block 17 and is rotatably connected to a push block 20. The push block 20 is fixedly connected to the upper surface of a vertical block 19.

[0029] like Figures 1 to 5As shown, the anti-disengagement mechanism also includes a positioning groove 25 on the hook body 7. A fixing groove 21 is provided on the side of hook block 19 near hook block 27, communicating with the positioning groove 25. A hook block 33 is slidably connected within the fixing groove 21. The vertical cross-sections of hook block 27, hook block 19, and hook block 33 are all crescent-shaped. Hook block 19 and hook block 323 are arranged in the same direction, while hook block 27 is arranged in the opposite direction. The tip of hook block 19 abuts against the inner wall of the hook body 7. A limiting block 28 is fixedly connected to the side of hook block 33 away from hook block 27. The limiting block 28 is slidably connected to the positioning groove 25. Multiple fixing blocks are fixedly connected to the side of the limiting block 28 away from hook block 323. Positioning spring 26, the end of positioning spring 26 away from limiting block 28 is fixedly connected to the inner wall of positioning groove 25, the extension path of positioning spring 26 is consistent with the path of one side of limiting block 28, hook block 3 23 can abut against hook block 2 17, wire rope 27 is fixedly connected to the side of limiting block 28 away from hook block 3 23, a slide 24 is opened on hook body 7, one end of slide 24 is connected to positioning groove 25, the other end of slide 24 is connected to slide groove 18, wire rope 27 and the end away from limiting block 28 are fixedly connected to vertical block 19 through wire rope 27, wire rope 27 and the end away from limiting block 28 are fixedly connected to vertical block 19 through slide 24, wire rope 27 slides in slide 24.

[0030] like Figures 1 to 5 As shown, the anti-disengagement mechanism also includes a limiting groove 48, which is formed through the hook body 7. A horizontal sliding rod 29 is fixedly connected to the limiting block 28, which passes through the limiting block 28 and is inserted into the limiting groove 48. The horizontal sliding rod 29 is slidably connected to the limiting groove 48.

[0031] In this solution, the crane is equipped with connecting parts such as hook rings. The positioning block 2 is connected and fixed to the crane through structures such as hook rings and pins. The pin connection and hook ring connection are common connection methods between existing cranes and lifting rope hooks, which will not be described in detail here.

[0032] In the initial state, under the support of the return spring 40, the push block 22 extends to the outside of the slide groove 18 towards one side of the vertical block 19. At this time, the hook block 27 does not contact the hook block 19, and the upper surface of the vertical block 19 abuts against the top wall of the slide groove 18. In the initial state, the positioning spring 26 is in a slightly compressed state. Then, under the action of the release force of the positioning spring 26, the hook block 3 23 abuts against the hook block 2 17, and pushes the hook block 3 23 to give the hook block 2 17 a certain pushing force, so that the abutment between the hook block 3 23 and the hook block 2 17 is tighter. When the rope buckle is inserted into the hook body 7, it can be pushed through the contact point between the rope buckle and hook block 23 and the hook body 7. During the insertion process, the rope buckle pushes hook block 23 upward, thereby causing hook block 23 and the limiting block 28 to move upward. During this process, the positioning spring 26 is compressed, causing it to deform further. When the rope buckle passes between hook block 23 and hook block 17, the release force of the positioning spring 26 causes hook block 23 to return to the contact state with hook block 17. The contact state between hook block 23 and hook block 17 has a certain limiting effect on the rope buckle hooked on the hook body 7, so that the rope buckle cannot easily come out of the hook body 7 when it is not under force. This prevents the rope buckle from easily separating from the hook body 7 before the item is lifted, thereby improving the safety of the anti-detachment device for the hoisting rope hook.

[0033] Furthermore, when the item is lifted, its own weight exerts a downward pulling force on the push block 22, causing it to move downwards. At this time, the push block 22 compresses the return spring 40, causing it to deform. The downward movement of the push block 22 simultaneously drives the push block 20 to move downwards. The push block 20 simultaneously pulls the rotating block 31, causing the hook block 27 to rotate around the hinge between the rotating seat 10 and the hook block 27. This causes the hook block 27 to rotate closer to the hook block 19 until it comes into contact with the hook block 19. At this time, the weight of the item causes the hook block 27 to come into contact with the hook block 19, sealing the opening of the hook body 7 and preventing the rope buckle from detaching from the hook body 7 during lifting. This further enhances the anti-detachment function, improves safety, and simplifies operation, thereby increasing the safety of the anti-detachment device for the lifting rope hook.

[0034] In this design, when the hook body 7 vibrates up and down, the rope buckle may temporarily detach from the push block 22. When the rope buckle detaches from the push block 22, the push block 22 is reset by the release force of the return spring 40, which in turn causes the hook block 27 to rotate back to its initial state. At the same time, the hook block 3 23 is pushed downward by the release force of the positioning spring 26 to abut against the hook block 27. Thus, while the hook block 27 detaches from the hook block 1 9, the hook block 3 23 abuts against the hook block 27. The abutment between the hook block 3 23 and the hook block 2 17 restricts the rope buckle, preventing it from easily coming off between the hook block 3 23 and the hook block 2 17. This provides double restriction and anti-detachment for the rope buckle, making it safer.

[0035] When using multiple rope hooks for hoisting, this solution ensures that the lower rope hook is pressed against the upper rope hook and abuts against the push block 22, resulting in higher safety for the lower rope hook and preventing it from easily detaching. The lower rope hook also exerts pressure on the push block 22, causing hook block 2 17 and hook block 1 9 to tightly abut against each other and seal the opening of the hook body 7. This prevents the upper rope hook from easily detaching from the hook body 7. Compared to traditional hoisting rope hook anti-detachment devices, this solution offers higher safety and lower risk of detachment when hoisting multiple rope hooks.

[0036] like Figures 1 to 2 As shown, the fixing assembly includes a bolt rod 5. Multiple fixing holes are provided on both fixing blocks 1. The bolt rod 5 passes through the fixing holes and is connected to the fixing nut 6. The two fixing blocks 1 are fixed together by tightening the fixing nut 6. A sliding hole 3 is provided on the fixing block 1. A positioning block 2 is fixedly connected to the fixing block 1. A sliding hole 4 is provided on the positioning block 2. After the two fixing blocks 1 are fixed, the sliding holes 4 on the two positioning blocks 2 can be aligned and abutted.

[0037] After the bolt rod 5 passes through the fixing holes on the two fixing blocks 1, the fixing nut 6 is tightened, which allows the two fixing blocks 1 to abut and fix the two fixing blocks 1. During disassembly, the fixing nut 6 can be removed directly, and then the bolt rod 5 can be removed, so that the individual fixing blocks 1 can be replaced, which facilitates the individual replacement and maintenance of the two fixing blocks 1 and the hook body 7.

[0038] like Figures 1 to 2As shown, the rotating assembly includes a motor 12, which is fixedly mounted on a fixed locking block 1. The structures on the two fixed locking blocks 1 are mirror images of each other. A support groove is provided on the top wall of the mounting groove 11. A threaded rod 13 is rotatably connected between the inner walls of the opposite sides of the support groove. One end of the threaded rod 13 rotatably passes through the outside of the fixed locking block 1 and is poweredly connected to the output end of the motor 12. A connecting block 14 is threadedly connected to the threaded rod 13. The connecting block 14 is located in the support groove and is slidably connected to the support groove. A slide rail groove is provided on the connecting block 14. A sliding block 15 is slidably connected in the slide rail groove. A fixed seat 16 is fixedly connected to the hook body 7. The end of the sliding block 15 away from the threaded rod 13 extends out of the outside of the connecting block 14 and is hinged to the fixed seat 16.

[0039] When motor 12 is started, it drives threaded rod 13 to rotate. During the rotation of threaded rod 13, connecting block 14 slides within support groove. As connecting block 14 moves, sliding block 15 moves within slide rail groove. Simultaneously, sliding block 15 also drives hook body 7 to rotate around the axis of positioning shaft 8. In this design, a control panel is installed in the crane's cab. The control panel is electrically connected to motor 12. By operating the control panel, the forward and reverse rotation, forward rotation duration, and reverse rotation duration of motor 12 can be controlled, thereby controlling the rotation angle of hook body 7 relative to fixed locking block 1. This is a commonly used technology in existing motor control and will not be elaborated upon here.

[0040] Initially, the hook body 7 is vertical. At this point, a rope buckle can be attached to the hook body 7 to lift and transfer items. When it is necessary to lower the item to the ground and disengage the hook body 7 from the rope buckle, the item must first be lowered to the ground so that the rope is no longer under the pull of the item. Because the rope is no longer under the pull of the item, hook block 2 17 returns to its state of contact with hook block 3 23. Then, the motor 12 is started, causing the motor 12 to rotate the hook body 7 away from the insertion rod 32. When the hook body 7 rotates to approximately 100 degrees (the threshold for rotation angle is usually between 95 and 120 degrees, preferably 100 degrees; within this threshold, the opening of the hook body faces downwards, facilitating the slippage of the rope buckle), hook block 3... With hook block 23 and hook block 27 facing downwards, and because both hook block 23 and hook block 27 are crescent-shaped, when the crane moves the hook body 7 upwards, the rope buckle is stretched and straightened, and the rope buckle will disengage from the hook body 7 between hook block 23 and hook block 27, thus completing the disassembly of the rope buckle. During the disassembly of the rope buckle, it is not necessary for a person to manually hold the hook body 7 to remove the rope buckle. Except for the initial lifting operation, no manual intervention is required during the subsequent transportation process, and no manual handling is required during the receiving step. Therefore, it avoids the situation where the goods fall abnormally during the lifting process and injure the personnel, saving manpower and making it safer, thereby improving the practicality and safety of the anti-disengagement device for the lifting rope hook.

[0041] In this solution, by setting two fixed locking blocks 1, after the two fixed locking blocks 1 are fixed by the fixing components, two kinds of materials can be simultaneously suspended on two hook bodies 7. The crane can then lift and transfer the two items at the same time. When one item needs to be unloaded, both items can be lowered to the ground first. Then, the corresponding motor 12 is started to rotate the corresponding hook body 7 to the disassembled state. Then, the crane is started to move the two hook bodies 7 upwards at the same time. The hook body 7, which is in a vertical state, will then safely lift the item again. The hook body 7, which is in a disassembled state, will detach from the hooked rope during the upward movement, thus completing the separate unloading of the items. The operation is simple, more flexible, and saves manpower, thereby improving the flexibility and convenience of the anti-detachment device for hoisting rope hooks.

[0042] like Figures 5 to 8As shown, the limiting mechanism includes a sliding cylinder 34, which is slidably sleeved on the insert rod 32. Multiple connecting springs 44 are fixedly connected to the bottom wall of the sliding cylinder 34. The upper ends of the connecting springs 44 are fixedly connected to the lower surface of the insert rod 32. A positioning hole is formed through the insert rod 32, and a rubber ring 33 is fixedly connected inside the positioning hole. A connecting hole 49 is formed through the sliding cylinder 34, through which the rope 39 can pass. A push plate 35 is provided on the lower side of the sliding cylinder 34, and multiple adjusting screw holes are formed through the push plate 35. A fixing bolt 47 is threaded into the hole. The fixing bolt 47 passes through the adjusting screw hole. The end of the fixing bolt 47 can be threaded into the bottom of the sliding cylinder 34. The end of the fixing bolt 47 can be threaded into the sliding cylinder 34. The lower end of the push block 22 is fixedly connected to the movable slide rod 42. The lower surface of the hook body 7 is provided with a movable groove 41. The lower end of the movable slide rod 42 slides into the movable groove 41 and is fixedly connected to a movable block 43. The movable block 43 is slidably connected to the movable groove 41. The push plate 35 can abut against the movable block 43.

[0043] like Figures 5 to 8 As shown, the limiting mechanism also includes two fixed arc plates 45, which are respectively fixedly connected to the top walls of the two connecting holes 49, and rubber arc blocks 46 are fixedly connected inside the fixed arc plates 45.

[0044] When in use, if the item is long or heavy, the rope can be threaded through the two hook bodies 7, the connecting hole 49, and the rubber ring 33, as shown in the attached diagram. Figure 5 As shown, at this time, the two hook bodies 7 can jointly bear the weight of the item. While sharing the weight, due to the horizontal distance between the two lifting points, the parallel parts of the lifting ropes are spaced out. At this time, the parallel lifting ropes with a large gap are less likely to twist and entangle, making the stability of the item during transportation higher. Simultaneously, when the item is lifted, its own weight causes the push block 22 to move downwards. During the downward movement of the push block 22, the hook block 27 rotates and comes into contact with the hook block 19 to prevent detachment. The downward movement of the push block 22 simultaneously causes the sliding rod 42 to move downwards, and the sliding rod 42 simultaneously causes the moving block 43 to move downwards. During the downward movement of the moving block 43, it comes into contact with the push plate 35 and pushes the push plate 35 downwards. The downward movement of the push plate 35 simultaneously causes the sliding cylinder 34 to move downwards, and the downward movement of the sliding cylinder 34 simultaneously causes the fixed arc plate 45 and the rubber arc block 46 to move downwards. As a result, the rope is squeezed between the bottom wall of the rubber ring 33 and the top wall of the rubber arc block 46. Since the rubber ring 33 and the rubber arc block 46 are both made of rubber, the squeezing of the rope by the rubber ring 33 and the rubber arc block 46 has a limiting and fixing effect on the rope. Under the action of friction generated by the squeezing, the lifting rope is prevented from sliding along the extension direction during the lifting process, which would cause the item to sway. This improves the stability of the item during the lifting process and further improves the safety and stability of the lifting rope hook anti-detachment device.

[0045] In this design, the distance between the push plate 35 and the sliding cylinder 34 can be adjusted by rotating the fixing bolt 47. The distance between the push plate 35 and the sliding cylinder 34 can also be adjusted by adjusting the depth of the fixing bolt 47 screwed into the sliding cylinder 34. This allows for a simultaneous adjustment of the distance the push plate 35 can move downward when the push block 22 slides downward into the groove 18. As a result, the rubber arc block 46 and the rubber ring 33 can clamp and fix ropes of different thicknesses, providing greater flexibility.

[0046] In this design, the rotating fixing bolt 47 is disengaged from the sliding cylinder 34, thereby allowing the push plate 35 to be removed from the sliding cylinder 34.

[0047] A method for preventing the hook from detaching from a hoisting rope hook, the method comprising: S1. Fix the two fixing blocks 1 with the fixing assembly, and then fix the two fixing blocks 1 to the lifting equipment; S2. Hook the rope buckle used for hoisting the item into the hook body 7. At this time, hook block 3 23 and hook block 2 17 can prevent the rope buckle from accidentally coming off when not being hoisted. S3. Start the rotating assembly to drive the hook body 7 to rotate to a vertical position, start the lifting equipment to lift the item. At this time, hook block 2 17 and hook block 1 9 abut against each other to prevent the rope buckle from coming off. S4. After the item is hoisted to the designated location and lands, the rope buckle is no longer under tension, and the rotating component is activated to drive the hook body 7 to rotate so that the opening of the hook body 7 faces downward. S5. Restart the lifting equipment to move the hook body 7 upward, and the rope buckle slides out between hook block 3 23 and hook block 2 17 to complete the unloading.
