[0027] See Figure 1-Figure 3 The present invention provides a sling for disassembling and assembling a starter head, comprising a hanging basket 1 and a protective component 3, wherein the protective component 3 is rotatably arranged on one side of the hanging basket 1;

[0028] The protective component 3 includes a vertical rod 31, a horizontal rod 32 and a positioning piece 33. The lower end of the vertical rod 31 is used to be rotatably connected to the hanging basket 1, the upper end of the vertical rod 31 is connected to one end of the horizontal rod 32, and the other end of the horizontal rod 32 is used to be connected to the positioning piece 33. The positioning piece 33 is used to fix the ingot head 4.

[0029] In this embodiment, the hanging basket 1 serves as a lifting tool to carry the ingot head 4. The ingot head 4 is lifted by connecting the hanging basket 1 with a lifting chain, so that the ingot head 4 can be smoothly installed into the ingot rod. When the ingot head 4 is removed, the hanging basket 1 is also connected with the lifting chain to carry the lifting ingot head 4, avoiding a series of problems caused by manual installation of the lifting ring; the provision of the protective component 3 is conducive to enhancing the stability of the ingot head 4 in the hanging basket 1, and can prevent the ingot head 4 from moving or even falling during the movement and installation of the ingot head 4. The vertical rod 31 of the protective component 3 is used to connect with the hanging basket 1, and the horizontal rod 32 and the positioning member 33 cooperate to facilitate the fixation of the ingot head 4 in the hanging basket 1.

[0030] See Figure 1 Preferably, the hanging basket 1 includes a load-bearing portion 11 and a side rail 12, the side rail 12 is arranged along the length direction of the load-bearing portion 11 (see the X-axis direction), and the side rail 12 is arranged on one side of the load-bearing portion 11, and the protective component 3 is rotatably arranged on the outside of the side rail 12.

[0031] Specifically, the side rails 12 are used to be fixed on the supporting portion 11 by welding.

[0032] The bearing portion 11 includes a bearing plate, which is a whole plate-shaped structure or a plate-shaped structure with a plurality of holes formed thereon. The side plate is welded to one side of the bearing plate in the longitudinal direction (see the X-axis direction);

[0033] The bearing portion 11 may further include four connecting beams, which are welded and connected in sequence to form a rectangular bottom frame. A plurality of reinforcing rods are evenly welded and fixed on the bottom frame, and the side panels are welded to the longer connecting beams on the bottom frame.

[0034] In this embodiment, the bearing portion 11 is used to bear the entire ingot head 4, and the side rails 12 and the protective component 3 cooperate with each other to effectively prevent the ingot head 4 from falling from the hanging basket 1. The protective component 3 is rotatably arranged on the outside of the side rails 12. The protective component 3 is flexibly adjusted to facilitate placing the ingot head 4 on the bearing portion 11 and then fixing the ingot head 4; wherein, the bearing portion 11 is a bearing plate, so that the overall strength of the bearing portion 11 is guaranteed, thereby improving the overall quality of the hanging basket 1, which is beneficial to extending the service life of the sling; or the bearing portion 11 is composed of four connecting beams welded together, and this structure is beneficial to reducing the overall weight of the bearing portion 11 and reducing material costs.

[0035] Preferably, a hoisting opening 13 is provided on a side of the hanging basket 1 away from the side rail 12 , and the starter head 4 is used to be loaded into the hanging basket 1 through the hoisting opening 13 .

[0036] In this embodiment, the provision of the hoisting opening 13 not only facilitates placing the starter head 4 into the hanging basket 1 , but also allows the starter head mounting surface 41 where the starter head 4 is connected to the starter rod to remain completely exposed, thereby facilitating the installation of the starter head 4 .

[0037] Preferably, a mounting tube 14 is fixed to the outer wall of the side rail 12, and the lower part of the vertical rod 31 is used to be rotatably connected to the mounting tube 14, so that the horizontal rod 32 is rotated to the top of the hanging basket 1 by cooperating with the vertical rod 31 and the mounting tube 14.

[0038] Specifically, a handle 34 is provided on the cross bar 32 , and the handle 34 is used to pull the protective component 3 to rotate.

[0039] In this embodiment, the vertical rod 31 cooperates with the mounting tube 14 to rotate the cross rod 32 to the top of the hanging basket 1, and the handle 34 is pulled along the circumferential direction. The handle 34 drives the cross rod 32 and the vertical rod 31 to rotate together, so that the cross rod 32 rotates to the top of the hanging basket 1, and then the positioning member 33 moves to the lifting port 13, so that the positioning member 33 can fix the ingot head 4 in the hanging basket 1 on one side of the lifting port 13, which is beneficial to prevent the ingot head 4 from falling from the lifting port 13, and also helps to prevent the ingot head 4 from moving relative to each other in the hanging basket 1.

[0040] See Figure 2 Preferably, the positioning member 33 includes an angle steel, and the angle steel includes a first side plate 331 and a second side plate 332 perpendicular to the first side plate 331, the first side plate 331 is used to be connected to the lower surface of the cross bar 32, and the second side plate 332 is used to be arranged on the side of the first side plate 331 away from the vertical bar 31.

[0041] Specifically, the first side plate 331 of the angle steel is used to be fixed to the lower surface of the cross bar 32 by welding; the first side plate 331 and the second side plate 332 are both square structures with a size of 75 mm*75 mm.

[0042] In this embodiment, when the cross bar 32 rotates to the top of the hanging basket 1, the lower end of the second side plate 332 of the positioning member 33 just abuts against the surface of the ingot starter 4, thereby achieving the purpose of fixing the position of the ingot starter 4 in the hanging basket 1.

[0043] Preferably, receiving columns are fixed to the upper ends of the four corners of the bearing portion 11 , and the side rails 12 are fixed between two of the receiving columns.

[0044] In this embodiment, the receiving column is used to connect with the lifting chain. The setting of the receiving column prevents the lifting chain from being directly connected to the bearing portion 11, which is beneficial to expanding the space of the hanging basket 1 in the vertical direction, making the hanging basket 1 and the ingot head 4 fit more appropriately, and is also beneficial to avoid the lifting chain directly contacting the ingot head 4 to generate friction and cause scratches on the ingot head 4.

[0045] Preferably, the supporting column includes a first supporting column 15 and a second supporting column 16, the first supporting column 15 is used to be arranged at both ends of the side rail 12, and the second supporting column 16 is used to be arranged on the side of the bearing part 11 opposite to the first supporting column 15, and a side rod 17 is connected between the first supporting column 15 and the second supporting column 16.

[0046] Specifically, two of the first receiving column 15 and the second receiving column 16 are provided, and two of the side rods 17 are also provided, and the two side rods 17 are located at both ends of the length direction of the hanging basket 1, and the first receiving column 15 and the second receiving column 16 are fixed to the receiving part by welding, and the first receiving column 15 is welded and fixed to the side rail 12; the side rod 17 is used to be fixed between the top end of the first receiving column 15 and the top end of the second receiving column 16 by welding.

[0047] In this embodiment, the two side rods 17 are located at both ends of the hanging basket 1 in the longitudinal direction. This structure has a blocking effect on both ends of the hanging basket 1 and can effectively prevent the ingot starter 4 from sliding out from both ends of the hanging basket 1.

[0048] See Figure 3 Preferably, the first supporting column 15 is higher than the second supporting column 16, so that the angle between the line between the top of the first supporting column 15 and the top of the second supporting column 16 and the projection line of the plane where the supporting part 11 is located is 5° to 15°.

[0049] Specifically, the two ends of the side rod 17 are respectively connected to the top of the first supporting column 15 and the top of the second supporting column 16, and the angle between the straight line where the side rod 17 is located and the projection line of the plane where the bearing part 11 is located ranges from 5° to 15°, and the angle is preferably 10°.

[0050] See Figure 3, in this embodiment, when the starter head 4 is installed, the angle between the starter head mounting surface 41 and the starter head contact surface 42 is 10°, so the angle between the line connecting the top of the first receiving column 15 and the top of the second receiving column 16 and the projection line of the plane where the bearing portion 11 is located is 10°. This structure corresponds to the 10° angle between the starter head mounting surface 41 and the starter head contact surface 42. During lifting, the starter head 4 is loaded into the hanging basket 1 and fixed by the protective component 3. Four lifting chains are provided to connect the four receiving columns. It is necessary to ensure that the lengths of the four lifting chains are equal. When the starter head 4 is lifted by the lifting equipment, the four lifting chains of equal length work to adjust the position of the hanging basket 1. The top ends of the four receiving columns are at the same height. At the same time, the starter head 4 is adjusted with the hanging basket 1 so that the starter head mounting surface 41 rotates 10° to maintain a horizontal state, which is conducive to ensuring that the starter head 4 is smoothly loaded into the starter rod.

[0051] Preferably, a reinforcing rib 18 is provided at the middle portion of the bearing portion 11 and the middle portion of the side rail 12 .

[0052] In this embodiment, the provision of the reinforcing ribs 18 strengthens the strength of the bearing portion 11 and the side rails 12 , thereby extending the service life of the sling.

[0053] Preferably, a plurality of lifting ears 2 are evenly arranged on the hanging basket 1 .

[0054] Specifically, the lifting lug 2 is used to connect with the lifting chain and the manual hoist. The lifting lug 2 is used to be fixed to the top of the four receiving columns by welding. The lifting lug 2 is also provided at the upper middle end of the side rail 12 facing the reinforcing rib 18. The lifting lugs 2 located at both ends of the hanging basket 1 are used to connect with the lifting chain, and the lifting lug 2 located in the middle of the side rail 12 is used to connect with the manual hoist.

[0055] In this embodiment, the lifting lug 2 is used to connect with the lifting chain and the manual hoist, which can essentially prevent lifting injury accidents caused by hidden dangers of the lifting ring and improper installation of the lifting ring; wherein, the lifting lug 2 at the upper end of the middle part of the side rail 12 is used to connect with the manual hoist, and the location of the lifting lug 2 in the middle part of the side rail 12 is conducive to the distribution of average force, so that the ingot head 4 can maintain balance when being lifted by the sling.

[0056] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present invention.
