Description

Technical Field

[0001] The present application relates to the field of lifting tools, and in particular to a special auxiliary lifting device for special-shaped building components and a lifting method thereof. Background Art

[0002] With the continuous development of my country's construction projects, the demand for reinforced concrete is constantly increasing. The original medium and high-rise buildings are no longer able to keep up with the current development. As land resources continue to shrink, more and more high-rise and super-high-rise buildings are constantly emerging. This requires sufficient compaction and reinforcement of the building foundation, and requires frequent and large-scale lifting of various steel structures or steel cages. During the lifting process, on the one hand, it is necessary to ensure the safety of the heavy objects when they are lifted, that is, the lifting equipment used has sufficient structural strength to carry the heavy objects; on the other hand, after the heavy objects are lifted, it is necessary to ensure that the lifting posture of the heavy objects is stable. In actual use, the heavy objects also need to be able to make a certain degree of steering so that the heavy objects can smoothly pass through obstacles or be accurately installed in the designated location. Therefore, certain performance requirements are placed on the lifting equipment.

[0003] In the current construction process, in order to ensure the balance of the heavy object during the lifting process, the main lifting rope 2 and the shoulder pole beam 1 are generally set under the crane hook, and then the multiple hook ropes 5 hooked on the heavy object are evenly arranged under the shoulder pole beam 1 to ensure that the heavy object can be lifted more balanced. Especially when lifting large heavy objects such as steel cages, in order to avoid the heavy object being deflected or swung under the crane hook due to the unstable center of gravity of the heavy object after being lifted, it is sometimes necessary to hook the hook ropes 5 on the shoulder pole beam 1 on the heavy object in a staggered manner. For specific lifting methods, please refer to Figure 1 .

[0004] Conventional hoists have high requirements on the shape of the heavy objects when lifting them. Before lifting, multiple lifting points need to be calculated as accurately as possible to ensure that after the heavy object is lifted, the heavy object itself will not spin due to unstable center of gravity. When conventional hoists are used to lift special-shaped building components, it takes a long time to calculate the lifting points before lifting the special-shaped building components, and it takes a long time to adjust the lifting posture after lifting. In addition, the heavy object needs to be turned quickly after lifting. After the heavy object is turned to a certain angle, the hook rope will twist and it is very easy to cause the heavy object to rotate, which makes it difficult to improve construction efficiency during on-site construction and the safety is also low. Summary of the Invention

[0005] In order to improve the problem of heavy objects spinning when turning after being lifted, the present application provides a special auxiliary lifting device for special-shaped building components and a lifting method thereof.

[0006] In the first aspect, the present application provides a special auxiliary lifting device for special-shaped building components, which adopts the following technical solutions:

[0007] An auxiliary lifting device specially designed for special-shaped building components includes a shoulder pole beam, two main lifting ropes are provided on one side of the shoulder pole beam in the length direction, and multiple lifting mechanisms are provided on the side of the shoulder pole beam away from the main lifting ropes. The lifting mechanism includes a secondary lifting rope rotatably connected to the shoulder pole beam, and the ends of multiple secondary lifting ropes away from the shoulder pole beam are commonly connected to an auxiliary plate, the secondary lifting ropes are rotatably connected to the auxiliary plate, and two hook ropes are provided on the side of the auxiliary plate away from the secondary lifting ropes, the two hook ropes are respectively provided at both ends of the auxiliary plate in the length direction, and buckles are provided at both ends of the hook ropes. The middle part of the hook rope in the length direction is slidably connected to the auxiliary plate.

[0008] By adopting the above technical solution, when lifting a heavy object, two main lifting ropes are installed on the hook of the crane, and then multiple hook ropes are hung on multiple lifting points of the heavy object through ring hooks. The shoulder pole beam is lifted by the crane until the main lifting rope, auxiliary lifting rope and hook rope are gradually tightened. Before the heavy object is about to leave the ground, the unstretched hook rope can be pulled to make its middle part slide on the auxiliary plate until the hook rope is tightened, so as to prevent the unstretched hook rope from sliding on the auxiliary plate after the heavy object is lifted, causing the auxiliary plate to shake. After the auxiliary plate is set, when the heavy object is lifted, the When the center of gravity is unstable during the lifting process and the heavy object shakes or deflects, the hook rope corresponding to the lifting point on the heavy object slides on the auxiliary plate to perform the first stage of buffering. Secondly, the auxiliary plate can also rotate on the auxiliary lifting rope to eliminate part of the deflection posture, and the independently arranged auxiliary lifting rope can further buffer the deflection force, effectively avoiding excessive shaking of the heavy object during the lifting process, improving the safety of the application during use, and at the same time, there is no need for overly precise measurement when setting the lifting point of the heavy object, which greatly reduces the lifting preparation time and indirectly improves the lifting efficiency.

[0009] After the heavy object is lifted, when the orientation of the heavy object needs to be adjusted, the construction workers can use a long pole to slowly rotate the heavy object. During this process, the auxiliary plate can rotate relative to the auxiliary lifting rope, and the auxiliary lifting rope can rotate relative to the shoulder pole beam. At the same time, the auxiliary lifting rope itself can rotate to a certain extent, and the rotation of the two lifting mechanisms relative to the shoulder pole beam is independent of each other and will not cause significant interference. Therefore, after the heavy object is lifted by this application, whether it rotates as a whole or deflects around a point, this application avoids interference with the rotation of the heavy object as much as possible and causes the heavy object to rotate after turning, thereby improving the practicality of this application.

[0010] Preferably, two fixed pulleys are provided for rotating on one side of the auxiliary plate away from the auxiliary suspension rope, the hook rope is passed through the arc-surface outer wall of the pulley on the fixed pulley, and the two fixed pulleys are arranged at both ends of the length direction of the auxiliary plate.

[0011] By adopting the above technical solution, when the center of gravity of the heavy object is deflected after the heavy object is lifted, the middle part of the hook rope slides on the pulley of the fixed pulley, reducing the resistance of the hook rope when moving on the auxiliary plate, making it smoother to adjust the center of gravity of the heavy object through the hook rope, and avoiding as much as possible the shaking of the hook rope and the heavy object caused by excessive resistance when the hook rope slides, thereby ensuring the safety of the heavy object when lifted by this application.

[0012] Preferably, a rotating lifting ring is fixedly connected to the upper end of the fixed pulley, a first shackle is connected to the rotating lifting ring, and the first shackle is installed on the auxiliary plate.

[0013] By adopting the above technical solution, the fixed pulley is installed on the auxiliary plate through the rotating lifting ring and the first shackle, so that the fixed pulley can be easily turned relative to the auxiliary plate. At the same time, it is more convenient to install and disassemble the fixed pulley, thereby saving effort when adjusting the orientation of the heavy object, and eliminating the need for multiple construction workers to coordinate adjustments. This not only improves the safety of the application when used, but also saves manpower.

[0014] Preferably, both ends of the auxiliary lifting rope are connected to a second shackle, and the two second shackles are respectively connected to the auxiliary plate and the shoulder pole beam; the end of the main lifting rope close to the shoulder pole beam is connected to a third shackle, and the third shackle is connected to the shoulder pole beam.

[0015] By adopting the above technical solution, the auxiliary lifting rope is connected to the auxiliary plate and the shoulder pole beam through the second shackle, and the main lifting rope is connected to the shoulder pole beam through the third shackle, so that the various components of the present application can be disassembled, which is convenient for transportation and on-site assembly; at the same time, the auxiliary lifting rope and the main lifting rope can be smoothly flipped at a certain angle on the second shackle and the third shackle, which is convenient for convenient position adjustment of heavy objects.

[0016] Preferably, a plurality of through-holes are provided on a side of the shoulder pole beam close to the hook rope, and the second shackle is mounted on the shoulder pole beam through the through-holes, and the plurality of through-holes are symmetrically arranged about a midline in the length direction of the shoulder pole beam.

[0017] By adopting the above technical solution, when the second shackles are installed in different through-holes, the distance between two adjacent shackles changes, so that heavy objects of different sizes can be lifted smoothly.

[0018] Preferably, both sides of the shoulder pole beam in the thickness direction are fixedly connected with reinforcing ribs along the length direction of the shoulder pole beam.

[0019] By adopting the above technical solution, the reinforcing ribs can strengthen the structural strength of the shoulder pole beam to a certain extent, so that the shoulder pole beam has a stronger bearing capacity for multiple lifting mechanisms, thereby increasing the maximum load of the lifting of heavy objects in this application.

[0020] Preferably, the main lifting rope and the auxiliary lifting rope are both configured as wire rope buckles connected end to end.

[0021] By adopting the above technical solution, when the wire rope buckle bears weight, the weight of the heavy object is shared by the straight wire ropes at both ends. Compared with a single-strand wire rope, it can carry twice the weight, further improving the maximum load of the heavy object lifted by this application and improving safety.

[0022] Preferably, the two main lifting ropes are hooked with a balance hook at one end away from the shoulder pole beam, and the balance hook includes a boom rotatably connected to the crane hook, and two hooks are integrally fixed to the lower end of the boom, and the two hooks are coplanar and symmetrically arranged with respect to the boom axis, and an anti-unhooking component is provided on the side of the boom close to the hook.

[0023] By adopting the above technical solution, the two symmetrically arranged hooks make it possible for the two main lifting ropes to be dispersed as much as possible after the two main lifting ropes are hooked on the hooks respectively, so that the forces on the two main lifting ropes are more balanced; the anti-unhooking component provides anti-unhooking protection for the main lifting ropes, thereby improving the safety of the application when used.

[0024] Preferably, the anti-drop hook assembly includes an anti-drop rod hingedly connected to the outer peripheral wall of the arc surface of the boom, the anti-drop rod extends away from one end of the boom to abut against the side of the hook close to the boom, and an elastic member is provided between the anti-drop rod and the boom; when the anti-drop rod abuts against the hook, the elastic member is in a compressed state.

[0025] By adopting the above technical solution, when the main lifting rope is installed on the balancing hook, the main lifting rope presses the anti-slip rod to flip toward the direction close to the lifting rod, and the elastic part is compressed and deformed. When the main lifting rope falls into the inside of the hook, the deformed elastic part pushes the anti-slip rod to flip toward the direction away from the lifting rod and finally presses against the inner wall of the upper end of the hook, thereby effectively preventing the main lifting rope from falling off from the open end of the hook when the balancing hook swings abnormally, causing a safety accident.

[0026] In a second aspect, the present application provides a lifting method for a special auxiliary lifting device for special-shaped building components, which adopts the following technical solutions:

[0027] A lifting method for a special auxiliary lifting device for special-shaped building components, comprising the following steps:

[0028] S1. Prepare the sling: Set lifting points on the object according to its shape and weight, set the corresponding hook ropes and lifting mechanisms according to the number of designed lifting points, install multiple lifting mechanisms on the shoulder beam and arrange them symmetrically about the midline of the shoulder beam's length.

[0029] S2. Adjust the lifting posture by installing the two main lifting ropes on the crane hook and lifting the shoulder pole beam with the crane until the main lifting ropes, the auxiliary lifting ropes, and the hook ropes are gradually tightened. During this process, gradually adjust the single set of hook ropes to make the lifting posture of the heavy object stable off the ground;

[0030] S3. To turn the load, after the load is lifted, the construction worker can hold a long pole at a certain distance from the load and turn the load horizontally. During the turning process, one end of the auxiliary lifting rope rotates on the shoulder beam, and the other end rotates on the auxiliary plate. The hook rope slidably connected to the auxiliary plate also twists to a certain extent, achieving precise turning of the load without rotation.

[0031] S4. The heavy object is lowered. After the orientation of the heavy object is adjusted, the crane transfers the heavy object to the top of the designated position. The crane then gradually lowers the heavy object until it is placed at the designated position.

[0032] By adopting the above-mentioned technical solution, after the heavy object is lifted off the ground by the present application, the heavy object can be moved to rotate slowly. During the rotation of the heavy object, the auxiliary plate can rotate relative to the auxiliary lifting rope, and the auxiliary lifting rope can rotate relative to the shoulder pole beam. At the same time, the auxiliary lifting rope itself can rotate to a certain extent, and the rotation of the two lifting mechanisms relative to the shoulder pole beam is independent of each other and will not cause major interference. Therefore, after the heavy object is lifted by the present application, whether it rotates as a whole or deflects around a point, the present application avoids interfering with the rotation of the heavy object as much as possible and causing the heavy object to rotate after turning, thereby improving the safety and practicality of the present application.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. When a heavy object is lifted off the ground and slowly rotated by the present invention, the auxiliary plate can rotate relative to the auxiliary lifting rope, and the auxiliary lifting rope can rotate relative to the shoulder pole beam. At the same time, the auxiliary lifting rope itself can rotate to a certain extent. The rotation of the two lifting mechanisms relative to the shoulder pole beam is independent of each other and will not cause significant interference. Therefore, after the heavy object is lifted by the present invention, whether it rotates as a whole or deflects around a point, the present invention avoids interference with the rotation of the heavy object as much as possible and causes the heavy object to rotate back after turning.

[0035] 2. When the center of gravity of the heavy object deflects after lifting, the middle part of the hook rope slides on the pulley of the fixed pulley, reducing the resistance of the hook rope when moving on the auxiliary plate, making it smoother to adjust the center of gravity of the heavy object through the hook rope, and avoiding as much as possible the shaking of the hook rope and the heavy object caused by excessive resistance when the hook rope slides, thus ensuring the safety of the heavy object when lifting according to this application;

[0036] 3. The reinforcing ribs can strengthen the structural strength of the shoulder pole beam to a certain extent, so that the shoulder pole beam has a stronger bearing capacity for multiple lifting mechanisms, thereby increasing the maximum load of the heavy objects lifted by this application.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 2-5 This application is described in further detail.

[0044] Example 1

[0045] The embodiment of the present application discloses a special auxiliary lifting device for special-shaped building components. Figure 2 and Figure 3The lifting mechanism comprises a lifting mechanism, a lifting mechanism comprising a lifting mechanism, a lifting mechanism comprising a lifting mechanism, a lifting mechanism comprising a secondary lifting rope 3 rotatably connected to the lifting mechanism, and a plurality of secondary lifting ropes 3 are connected to an auxiliary plate 4 at one end away from the lifting mechanism. The secondary lifting rope 3 is rotatably connected to the auxiliary plate 4, and the secondary lifting rope 3 is rotatably connected to the auxiliary plate 4. The auxiliary plate 4 is provided with two hook ropes 5 at one end away from the secondary lifting rope 3. The two hook ropes 5 are respectively arranged at the two ends of the auxiliary plate 4 in the length direction, and both ends of the hook rope 5 are provided with buckles 6, which are formed by bending the hook rope 5 as a whole; the middle part of the hook rope 5 in the length direction is slidably connected to the auxiliary plate 4, and the auxiliary plate 4 is rotatably provided with two fixed pulleys 7 on the side away from the secondary lifting rope 3. The hook rope 5 is passed through the outer peripheral wall of the arc surface of the pulley on the fixed pulley 7, and the two fixed pulleys 7 are respectively arranged at the two ends of the auxiliary plate 4 in the length direction.

[0046] When lifting a heavy object, install two main lifting ropes 2 on the hook of the crane, and then hook multiple hook ropes 5 on multiple lifting points of the heavy object through ring buckles 6. Lift the main lifting ropes 2 and the shoulder pole beam 1 by the crane until the main lifting ropes 2, the auxiliary lifting ropes 3 and the hook ropes 5 are gradually tightened. Before the heavy object is about to leave the ground, pull the unstretched hook ropes 5 so that their middle parts slide on the auxiliary plate 4 until the hook ropes 5 are tightened, so as to prevent the unstretched hook ropes 5 from being tightened after the heavy object is lifted. The auxiliary plate 4 slides and causes the auxiliary plate 4 to shake; the heavy object can also be lifted directly. When the center of gravity of the heavy object is deflected after lifting, the middle part of the hook rope 5 slides on the pulley of the fixed pulley 7, reducing the resistance of the hook rope 5 when moving on the auxiliary plate 4, making it smoother to adjust the center of gravity of the heavy object through the hook rope 5, and avoiding as much as possible the shaking of the hook rope 5 and the heavy object caused by excessive obstruction when sliding the hook rope 5, thereby ensuring the safety of the heavy object when lifting in this application.

[0047] After the auxiliary plate 4 is set, when the center of gravity of the heavy object is unstable during the lifting process, causing the heavy object to shake or deflect, the hook rope 5 corresponding to the lifting point on the heavy object slides on the auxiliary plate 4 to perform the first stage of buffering. Secondly, the auxiliary plate 4 can also rotate on the auxiliary lifting rope 3 to eliminate part of the deflection posture, and the independently set auxiliary lifting rope 3 can further buffer the deflection force, effectively avoiding excessive shaking of the heavy object during the lifting process, improving the safety of the application during use, and at the same time, there is no need for overly precise measurement when setting the lifting point of the heavy object, which greatly reduces the lifting preparation time and indirectly improves the lifting efficiency.

[0048] After the heavy object is lifted, when the orientation of the heavy object needs to be adjusted, the construction workers can use a long pole to slowly rotate the heavy object. During this process, the auxiliary plate 4 can rotate relative to the auxiliary lifting rope 3, and the auxiliary lifting rope 3 can rotate relative to the shoulder pole beam 1. At the same time, the auxiliary lifting rope 3 itself can rotate to a certain extent, and the rotation of the two lifting mechanisms relative to the shoulder pole beam 1 is independent of each other, and will not cause major interference. Therefore, after the heavy object is lifted by this application, whether it rotates as a whole or deflects around a point, this application avoids interference with the rotation of the heavy object as much as possible and causes the heavy object to rotate after turning, thereby improving the practicality of this application.

[0049] Reference Figure 2 and Figure 3 The upper end of the fixed pulley 7 is fixedly connected to a rotating ring 8, and the rotating ring 8 is connected to a first shackle 9, which is installed on the auxiliary plate 4; both ends of the auxiliary lifting rope 3 are connected to the second shackle 10, and the two second shackles 10 are respectively connected to the auxiliary plate 4 and the shoulder pole beam 1; the end of the main lifting rope 2 close to the shoulder pole beam 1 is connected to the third shackle 11, and the third shackle 11 is connected to the shoulder pole beam 1.

[0050] The fixed pulley 7 is installed on the auxiliary plate 4 through the rotating lifting ring 8 and the first shackle 9, so that the fixed pulley 7 can be easily turned relative to the auxiliary plate 4, and it is also more convenient to install and remove the fixed pulley 7; and the auxiliary lifting rope 3 is connected to the auxiliary plate 4 and the shoulder pole beam 1 through the second shackle 10, and the main lifting rope 2 is connected to the shoulder pole beam 1 through the third shackle 11, so that each component of the present application can be disassembled, which is convenient for transportation and on-site assembly. At the same time, the auxiliary lifting rope 3 and the main lifting rope 2 can be smoothly flipped at a certain angle on the second shackle 10 and the third shackle 11, so that it is more labor-saving when adjusting the orientation of the heavy object, and there is no need for multiple construction workers to coordinate adjustments, which not only improves the safety of the application when used, but also saves manpower.

[0051] Reference Figure 2 and Figure 3 A plurality of through-holes 12 are provided on one side of the carrying pole beam 1 close to the hook rope 5. In the present application, there are five through-holes 12. The second shackle 10 is installed on the carrying pole beam 1 through the through-holes 12. The five through-holes 12 are arranged along the length direction of the carrying pole beam 1 and are symmetrically arranged with the center line of the length direction of the carrying pole beam 1; reinforcing ribs 13 along the length direction of the carrying pole beam 1 are fixed on both sides of the thickness direction of the carrying pole beam 1, and the main lifting rope 2 and the auxiliary lifting rope 3 are both provided with wire rope buckles connected end to end.

[0052] When the second shackle 10 is installed in different through-holes 12, the distance between two adjacent shackles changes, and heavy objects of different sizes can be lifted smoothly; the reinforcing ribs 13 can strengthen the structural strength of the shoulder pole beam 1 to a certain extent, so that the shoulder pole beam 1 has a stronger load-bearing capacity for multiple lifting mechanisms, and the maximum load of the heavy objects lifted by this application is improved. When the wire rope buckle bears the weight, the weight of the heavy object is shared by the straight wire ropes at both ends. Compared with the single-strand wire rope, it can carry twice the weight, further improving the maximum load of the heavy objects lifted by this application and improving safety.

[0053] Reference Figure 2 and Figure 4 The two main lifting ropes 2 are hooked with a balancing hook at one end away from the shoulder beam 1. The balancing hook includes a boom 14 rotatably connected to the crane hook. Two hooks 15 are integrally fixed to the lower end of the boom 14. The two hooks 15 are coplanar and symmetrically arranged with the axis of the boom 14; an anti-unhooking component is provided on the side of the boom 14 close to the hook 15, and the anti-unhooking component includes an anti-unhooking rod 16 hingedly connected to the outer peripheral wall of the curved surface of the boom 14, and the anti-unhooking rod 16 extends from one end of the boom 14 to abut against the side of the open end of the hook 15 close to the boom 14. An elastic member 17 is provided between the anti-unhooking rod 16 and the boom 14. When the anti-unhooking rod 16 abuts against the hook 15, the elastic member 17 is in a compressed state.

[0054] When the main lifting rope 2 is installed on the balancing hook, the main lifting rope 2 presses the anti-falling rod 16 to flip the anti-falling rod 16 toward the direction close to the hanging rod 14, and the elastic member 17 is compressed and deformed. When the main lifting rope 2 falls into the inner side of the opening of the hook 15, the deformed elastic member 17 pushes the anti-falling rod 16 to flip toward the direction away from the hanging rod 14 and finally presses against the inner wall of the open end of the hook 15, which can effectively prevent the main lifting rope 2 from falling off from the open end of the hook 15 when the balancing hook swings abnormally and causing a safety accident; the two symmetrically arranged hooks 15 ensure that after the two main lifting ropes 2 are hooked on the hooks 15 respectively, the two main lifting ropes 2 are dispersed as much as possible, so that the forces on the two main lifting ropes 2 are more balanced.

[0055] The implementation principle of the auxiliary lifting device for special-shaped building components and the lifting method thereof in the embodiment of the present application is as follows: after the boom 14 is installed on the rotating shaft of the crane hook, the two main lifting ropes 2 are hooked on the two hooks 15, and the ring buckles 6 on the multiple hook ropes 5 are respectively connected to the multiple lifting points according to the lifting points selected on the heavy object. The main lifting rope 2 and the shoulder pole beam 1 are lifted by the crane until the main lifting rope 2, the auxiliary lifting rope 3 and the hook rope 5 are gradually tightened. During this process, the middle part of the hook rope 5 slides on the pulley of the fixed pulley 7 to ensure that the lifting posture of the heavy object is stable as much as possible after it is lifted off the ground When the orientation of the heavy object needs to be adjusted, the construction workers can use a long pole to slowly rotate the heavy object. During this process, the auxiliary plate 4 can rotate relative to the auxiliary lifting rope 3, and the auxiliary lifting rope 3 can rotate relative to the shoulder pole beam 1. At the same time, the auxiliary lifting rope 3 itself can rotate to a certain extent, and the rotation of the two lifting mechanisms relative to the shoulder pole beam 1 is independent of each other, and will not cause significant interference. Therefore, after the heavy object is lifted by this application, whether it rotates as a whole or deflects around a point, this application avoids interference with the rotation of the heavy object as much as possible and causes the heavy object to rotate back after turning, thereby improving the practicality of this application.

[0056] Example 2

[0057] The embodiment of the present application discloses a lifting method of a special auxiliary lifting device for special-shaped building components. Figure 5 The lifting method of the auxiliary lifting device for special-shaped building components includes the following steps:

[0058] S1. Prepare the sling. Set multiple lifting points on the object according to its shape and weight. Set the corresponding hook rope 5 and lifting mechanism according to the number of designed lifting points. Install multiple lifting mechanisms on the pole beam 1 and make multiple lifting mechanisms symmetrical to the midline of the pole beam 1 in the longitudinal direction.

[0059] S2. Adjust the lifting posture: Install the two main lifting ropes 2 onto the two hooks 15, and install the boom 14 onto the crane hook. Connect the buckles 6 of the multiple hook ropes 5 to the multiple lifting points. Use the crane to lift the shoulder beam 1 until the main lifting ropes 2, auxiliary lifting ropes 3, and hook ropes 5 are gradually tightened. During this process, the middle part of the hook rope 5 slides autonomously on the fixed pulley 7 to stabilize the lifting posture of the heavy object off the ground.

[0060] S3. To turn the load, after the load is lifted off the ground, the construction worker can hold a long pole at a certain distance from the load and turn the load horizontally. During the turning process, one end of the auxiliary lifting rope 3 rotates on the shoulder pole beam 1 through the second shackle 10, and the other end rotates on the auxiliary plate 4 through the second shackle 10. The auxiliary lifting rope 3 itself can also be twisted to a certain extent. The fixed pulley 7 connected to the auxiliary plate 4 through the rotating lifting ring 8 can also drive the hook rope 5 connected to it to rotate, so as to achieve precise turning of the load without rotation.

[0061] S4. The heavy object is lowered. After the position of the heavy object is adjusted, the crane transfers the heavy object to the top of the designated position. The crane then gradually lowers the heavy object until it is placed at the designated position.

[0062] When heavy objects are lifted by this method, due to the smooth self-sliding property of the hook rope 5 in the fixed pulley 7 and the independent rotation property of the multiple auxiliary lifting ropes 3, even if the center of gravity of the heavy object shifts after being lifted, the hook rope 5 and the auxiliary lifting rope 3 can be quickly and independently adjusted until the center of gravity of the heavy object is balanced and stabilized. There is no need to spend a lot of time on selecting the center of gravity of the heavy object, which greatly shortens the lifting time when using this application; when the heavy object is lifted and rotated, the two auxiliary lifting ropes 3 rotate independently relative to the shoulder beam 1 and will not cause significant interference. Therefore, after the heavy object is lifted by the method of this application, no matter whether the heavy object rotates as a whole or deflects around a point, it is less likely for the heavy object to rotate back after turning in the method of this application, which improves the safety and practicality of this application.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
