Description

Technical Field

[0001] This utility model relates to the field of lifting and suspension slings technology, and in particular to a lifting sling for lifting and suspension. Background Technology

[0002] Lifting slings are key components used in lifting operations to connect the crane to the object being lifted. They are mainly used for lifting, traction, tensioning, and load-bearing operations. Their core functions include transferring loads, fixing the position of objects, and distributing forces.

[0003] Normally, lifting equipment is equipped with one hook. When one hook is insufficient to complete the lifting work, multiple hooks are added below the hook to carry out the lifting work. However, directly adding multiple hooks will cause the force generated by the swaying of the load in the air to act directly on the top hook itself, causing the top hook to sway and easily causing the goods to tilt or overturn. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A lifting sling for lifting and suspending, comprising: a main lifting sling;

[0008] Lifting rings are provided on the upper surface of the main lifting device;

[0009] Both the main lifting device and the side lifting device are fixedly equipped with connecting plates at their bottoms;

[0010] The hook cable is set below the main lifting device via the connecting plate.

[0011] As an improvement to the above technical solution, the upper surfaces of the main lifting device and the side lifting device are provided with connection holes, and the bottom of the lifting ring is inserted into the connection hole.

[0012] As an improvement to the above technical solution, the number of the lifting rings and the hooks are both three sets, arranged in sequence at equal intervals.

[0013] As an improvement to the above technical solution, the surface of the limiting rod is provided with a plurality of limiting holes, and a limiting buckle is inserted into the surface of the limiting rod through the limiting holes.

[0014] As an improvement to the above technical solution, the side of the connecting plate is provided with a strip-shaped through groove, and the bottom of the strip-shaped through groove is provided with several grooves, and the top end of the hook is fitted into the groove.

[0015] As an improvement to the above technical solution, the hook includes a sling, a bolt, a collar, a nut, and a hook. The sling is located at the bottom of the connecting plate, the bolt is fixedly connected to the bottom of the sling, the collar is sleeved on the lower end of the bolt, the nut is threadedly connected to the bottom end of the bolt inside the collar, and the hook is movably located at the bottom of the collar.

[0016] As an improvement to the above technical solution, the top of the sling has a locking sleeve, which is fitted into the strip-shaped through groove, and the height of the strip-shaped through groove is greater than the bolt diameter of the locking sleeve.

[0017] As an improvement to the above technical solution, the bolts, collars, and nuts are all made of alloy steel.

[0018] The beneficial effects of this utility model are:

[0019] 1. By designing the main spreader and side spreader, the original single force point is transformed into two force points. With the help of the limit rod, the distance between the main spreader and the side spreader can be adjusted, thereby expanding the lifting force range. When the cargo sways in the air, the force will first cause the bottom hook to sway, and then be transmitted to the main spreader and side spreader. Because the distance between the main spreader and the side spreader is widened, the force range is expanded. In this series of processes, the force generated by the swaying will be gradually reduced. At this time, the swaying force will not affect the initial top spreader of the lifting equipment.

[0020] 2. The design of three sets of lifting rings and three sets of hooks further reduces the negative impact of swaying due to the stability of the triangle, and the triangular lifting method can also prevent the goods from tipping over or overturning. Attached Figure Description

[0029] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0030] Normally, lifting equipment is equipped with one hook. When one hook is insufficient to complete the lifting work, multiple hooks are added below the hook to carry out the lifting work. However, directly adding multiple hooks will cause the force generated by the swaying of the load in the air to act directly on the top hook itself, causing the top hook to sway and easily causing the goods to tilt or overturn.

[0031] To resolve this issue, please refer to [link / reference]. Figures 1-4 A lifting sling for lifting and suspending, comprising: a main lifting sling 1;

[0032] The side lifting device 2 is set on the side of the main lifting device 1, and two sets of limit rods 3 are symmetrically arranged on the side of the side lifting device 2 closest to the main lifting device 1.

[0033] The main lifting device 1 has symmetrical through holes 101 on its side, and the limiting rod 3 passes through the through holes 101;

[0034] Lifting ring 102 is provided on the upper surface of the main lifting device 1;

[0035] Both the main lifting device 1 and the side lifting device 2 are fixedly equipped with connecting plates 4 at their bottoms;

[0036] The hook 5 is set below the main lifting device 1 via the connecting plate 4.

[0037] In use, the main lifting device 1 and the side lifting device 2 are connected to the lifting equipment via the lifting ring 102. Either the main lifting device 1 or the side lifting device 2 can be pulled to separate them. Then, the hook 5 is fitted onto the bottom of the main lifting device 1 or the side lifting device 2 for lifting operations. Through the design of the main lifting device 1 and the side lifting device 2, the original single force point is transformed into two force points. With the help of the limit rod 3, the distance between the main lifting device 1 and the side lifting device 2 can be adjusted, thereby expanding the lifting force range. When the goods sway in the air, the force will first cause the bottom hook 5 to sway, and then be transmitted to the main lifting device 1 and the side lifting device 2. Because the distance between the main lifting device 1 and the side lifting device 2 is widened, the force range is expanded. In this series of processes, the force generated by the swaying will be gradually reduced. At this time, the swaying force will not affect the initial top lifting device of the lifting equipment.

[0038] In one implementation, please refer to Figures 1-4 Both the main lifting device 1 and the side lifting device 2 have connection holes 6 on their upper surfaces, and the bottom of the lifting ring 102 is inserted into the connection hole 6.

[0039] During assembly and use, the connection between the lifting ring 102 and the connecting hole 6 can be in various ways. For example, the bottom surface of the lifting ring 102 and the inner wall of the connecting hole 6 can both be threaded, and the connection can be made by threading. Alternatively, the lifting ring 102 can be directly inserted into the connecting hole 6 and then welded.

[0040] In one implementation, please refer to Figures 1-4 There are three sets of each of the lifting rings 102 and the hooks 5, arranged at equal intervals.

[0041] During assembly and use, the positions of the lifting rings 102 and hooks 5 can be adjusted at will. The optimal method is triangular assembly and fixation. The design of three sets of lifting rings 102 and three sets of hooks 5 further reduces the negative impact of swaying due to the stability of the triangle. Triangular lifting can also prevent the goods from tipping over or turning over.

[0042] In one implementation, please refer to Figures 1-4 The surface of the limiting rod 3 is provided with several limiting holes 301, and the surface of the limiting rod 3 is provided with limiting buckles 302 through the limiting holes 301.

[0043] When in use, when the main lifting device 1 and the side lifting device 2 are pulled to the maximum distance, the limit buckle 302 is inserted into the limit hole 301 on the upper surface of the main lifting device 1 to limit the limit rod 3, so as to prevent the main lifting device 1 and the side lifting device 2 from shifting during the lifting process and causing the goods to shake.

[0044] In one implementation, please refer to Figures 1-4The side of the connecting plate 4 is provided with a strip-shaped through groove 401, and the bottom of the strip-shaped through groove 401 is provided with several grooves 4011. The top of the hook 5 is fitted into the groove 4011.

[0045] During assembly and use, the hook 5 can be moved and adjusted freely within the strip groove 401. After the position is determined, the hook 5 is moved into the groove 4011. The groove 4011 can limit the hook 5 and prevent the hook 5 from shifting during the lifting process.

[0046] In one implementation, please refer to Figures 5-7 The hook 5 includes a sling 501, a bolt 502, a collar 503, a nut 504, and a hook 505. The sling 501 is located at the bottom of the connecting plate 4. The bolt 502 is fixedly connected to the bottom of the sling 501. The collar 503 is sleeved on the lower end of the bolt 502. The nut 504 is threadedly connected to the bottom end of the bolt 502 inside the collar 503. The hook 505 is movably located at the bottom of the collar 503.

[0047] When assembling and using the hook 5, the layer-by-layer disassembly design facilitates loading and unloading. If any of the components, such as the sling 501, bolt 502, collar 503, nut 504, or hook 505, is damaged, it can be disassembled and replaced at any time.

[0048] In one implementation, please refer to Figures 1-7 The top of the sling 501 has a locking sleeve 5011, which is fitted into a strip groove 401. The height of the strip groove 401 is greater than the bolt diameter of the locking sleeve 5011.

[0049] When in use, the height of the strip groove 401 is greater than the bolt diameter of the lock 5011, which makes it easy for the lock 5011 to move and adjust its position freely within the strip groove 401.

[0050] In one implementation, please refer to Figures 5-7 Bolt 502, collar 503 and nut 504 are all made of alloy steel.

[0051] During use, the bolts 502, collars 503, and nuts 504 made of alloy steel have a longer service life, and the alloy steel material has stronger tensile and shear resistance and better load-bearing capacity.

[0052] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
