Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Example 1: The specific structure of this utility model is as follows: Please refer to the appendix. Figure 1-6 This utility model discloses a lifting equipment with a C-shaped lifting device structure, including a fixed beam 1 and a main beam 3 that is rotatably connected to the fixed beam 1 and rotates along a horizontal plane. Specifically, the fixed beam 1 and the main beam 3 are connected by a turntable 2. The fixed beam 1 is in a fixed state, and the main beam 3 can rotate circumferentially along the horizontal plane via the turntable 2.

[0023] The lifting equipment also includes at least one set of C-type lifting sling assembly 100, a first rigging 4, and a second rigging 7. For example... Figure 1 As shown, there are two sets of C-type spreader assemblies 100, and each set of C-type spreader assemblies 100 has two C-type spreaders 5. Each C-type spreader 5 is equipped with two first riggings 4, and each lifting lug is connected to the main beam 3 by one first rigging 4.

[0024] The C-type spreader assembly 100 includes at least two C-type spreaders 5 and multiple connecting beams 6. Each pair of adjacent C-type spreaders 5 is connected by multiple connecting beams 6, which are flange connecting beams. The C-shaped openings of each C-type spreader 5 are all lateral and have the same orientation and height. Figure 1 As shown, in a set of C-type spreader assemblies 100, two C-type spreaders 5 are connected by three flange connecting beams. Two flange connecting beams connect the upper crossbars of the two C-type spreaders 5, and the two flange connecting beams are parallel and spaced apart. Each C-type spreader 5 has two lifting lugs at its top, spaced apart. In one C-type spreader 5, the horizontal center of gravity is located between the two lifting lugs. When multiple sets of C-type spreader assemblies 100 are unloaded, their horizontal center of gravity is also located between the two lifting lugs.

[0025] The first rigging 4 is provided in multiple ways, and each C-type lifting device 5 is connected to the main beam 3 through at least two first rigging 4s; the first rigging 4 includes a steel wire rope 41 and two first shackles 42, and the two ends of the steel wire rope 41 are connected to the two first shackles 42 one by one; one of the first shackles 42 is connected to the main beam 3, and the other first shackle 42 is connected to the lifting lug.

[0026] The second rigging 7 has at least two slings, and its first end is connected to the bottom surface of the C-shaped opening of the C-shaped lifting device 5. That is, a connection point is provided in the upper region of the bottom surface of the C-shaped opening. The second end of the C-shaped lifting device 5 is used to connect to the object 12 being lifted. After the second rigging 7 is fixed, it forms an angle with the bottom surface of the C-shaped opening. Figure 1 As shown, each of the two sets of C-type lifting assemblies 100 is equipped with two second rigging 7, which are respectively set at the two C-type lifting assemblies 5 at the outer ends of the two sets of C-type lifting assemblies 100. That is, when the top plate enters the C-type lifting assemblies 5, the lifting points on the upper surface of the top plate are fixed by the two second rigging 7.

[0027] An adjustable screw 9 is installed on the bottom surface of the C-shaped opening of the C-type lifting device 5. The adjustable screw 9 points towards the C-shaped opening and is locked and released by double nuts. The function of the adjustable screw 9 is to abut against the top plate so that one side of the top plate is positioned. Its main function is to adjust and lock the center of gravity of the overall lifting, thereby ensuring that the top plate can be successfully lifted into place.

[0028] The lower plane of the C-shaped opening of the C-type lifting device 5 is designated as a support surface, and this support surface is provided with multiple support pad assemblies 10 of equal height. Each support pad assembly 10 includes: A fixing plate 106 is welded to the supporting surface, and the upper surface of the fixing plate 106 is provided with at least two tenons 105. The main steel plate 103 has a tenon 101 welded to its lower surface to mate with the tenon groove 105; The pad 104 is fitted onto the tenon 101 and is tightly attached to the lower surface of the main steel plate 103; The rigid rubber sheet 102 is bonded to the upper surface of the main steel plate 103.

[0029] The top plate is hoisted into the C-shaped opening and supported by the support pad assembly 10, so that the top plate is stably hoisted.

[0030] The second rigging 7 includes a spiral buckle assembly, a lifting eyelet 73, a second shackle 74, and a duckbill buckle 75 connected in sequence.

[0031] The spiral buckle assembly includes a spiral buckle 72 and two third shackles 71 connected to both ends of the spiral buckle 72 by a screw thread. One of the third shackles 71 is connected to the bottom surface of the C-shaped opening of the C-shaped lifting device 5, and the other third shackle 71 forms a closed interlocking structure with the lifting ring 73.

[0032] The object to be lifted 12 is a top plate, which is a U-shaped structural component. During lifting, the U-shaped opening of the top plate faces downwards, and its lifting surface is provided with multiple lifting points. Each lifting point includes a semi-circular groove 121 and a T-shaped column 122 vertically fixed to the bottom surface of the semi-circular groove. The duckbill buckle 75 can fasten onto the T-shaped column 122 to form a fastening structure. The overall center of gravity of the top plate during lifting is offset by approximately 0.05mm from the center of the downward rotating lifting device in the Z horizontal direction. The offset distance is small and does not affect the lifting operation.

[0033] In actual use, first adjust the adjustable screw 9 of the C-type hanger 5 according to the size and shape of the top plate so that it can abut against the top plate. The adjustable screw 9 is used to position the top plate.

[0034] The duckbill buckle 75 of the second rigging 7 is fastened to the T-shaped column 122, and its other end is fixed to the bottom connection point of the C-shaped opening of the C-shaped spreader 5. According to the weight of the top plate and the lifting requirements, the spiral buckle 72 in the second rigging 7 is adjusted to straighten the second rigging 7 and ensure a secure connection. Finally, through the cooperation of the fixed beam 1 and the main beam 3, the lifting equipment is moved to a suitable position for lifting operations. During the lifting process, the support pad assembly 10 of the C-shaped spreader 5 provides good buffering, support, and load-sharing protection for the top plate, ensuring that the surface of the top plate is not damaged and that the spreader is evenly stressed.

[0035] Example 2: like Figure 5 As shown, the concrete support 11 is a strip-shaped component connected to the upper horizontal bar of the C-type lifting device 5. The concrete support hinders the normal vertical lifting of the top slab. Therefore, developing an arched lifting device for lifting the top slab can improve production efficiency and save the time and cost spent on dismantling the concrete support.

[0036] In summary, the lifting equipment of this utility model, through the design of multiple sets of C-type lifting tool components, can adapt to objects of different sizes and shapes, thereby improving the versatility and adaptability of the lifting equipment. The C-type lifting device of this utility model is connected to the main beam by multiple first riggings, and the second rigging is connected to the C-type lifting device and the object being lifted. This method ensures the stability and reliability of the lifting process and effectively reduces the swaying and tilting of the object being lifted during the lifting process. In the C-type lifting device of this utility model, the adjustable screw and support pad assembly on the bottom surface of the C-shaped opening can better limit and protect the object being lifted, while also enhancing the practicality of the lifting device.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
