[0002] The packaging box of an aircraft engine has a metal frame, which is welded from steel plates. The steel plates need to be transported using a sling, which is usually a magnetic sling that uses suction cups to lift the steel plates.

[0003] The existing suction cups generate magnetic force to lift the steel plates when they are powered on. If a line fault causes a sudden power outage, the magnetic force disappears and the steel plates lose traction and fall, posing a threat to on-site facilities and the personal safety of workers.

[0004] In view of the above problems, the utility model provides a sling for conveying large metal parts. Utility Model Content

[0005] The purpose of the utility model is to provide a sling for conveying large metal parts. By adding adjustable hooks on both sides of multiple suction cups to further fix the two sides of the steel plate, the steel plate can be prevented from falling due to demagnetization of the suction cups, thereby protecting on-site facilities and the personal safety of workers, thereby solving the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sling for conveying large metal parts, comprising a magnetic sling body and a plurality of suction cups, U-shaped plates are symmetrically arranged on both sides of the upper end of the suction cup, a rotating disk is rotatably arranged on the inner side of the U-shaped plate, and a plurality of evenly distributed first holes are opened in the circumferential direction of the side surface of the rotating disk, a first insertion rod is movably arranged in the side wall of the U-shaped plate, a first spring is sleeved on the outer side of the first insertion rod, a rectangular box is fixed on the outer circumference of the rotating disk, a telescopic plate is movably arranged in the rectangular box, a plurality of evenly distributed second holes are opened inside the telescopic plate along the length direction, a second insertion rod is movably arranged in the side wall of the open end of the rectangular box, a second spring is sleeved on the outer side of the second insertion rod, and a hook is fixed on the end of the telescopic plate.

[0007] Furthermore, a rotating shaft is fixedly installed in the middle of the rotating disk, and the outer sides of both ends of the rotating shaft are rotatably connected to the side walls of the U-shaped plate through bearings.

[0008] Furthermore, the first insertion rod is slidably connected to the side wall of the U-shaped plate, a first handle is fixed to the end of the first insertion rod, and the first spring is tightly connected between the outer side of the U-shaped plate and the first handle. The first spring drives the first insertion rod away from the first handle and engages with the first hole.

[0009] Furthermore, the outer side of the telescopic plate is slidably connected to the inner side of the rectangular box, and the telescopic plate and the inner side of the rectangular box match in size.

[0010] Furthermore, the second insertion rod is slidably connected to the side wall of the open end of the rectangular box, a second handle is fixed to the end of the second insertion rod, and the second spring is tightly connected between the rectangular box and the second handle. The second spring drives the second insertion rod away from the second handle and engages with the second hole.

[0011] Furthermore, a support column is fixedly provided in the middle of the bottom end of the U-shaped plate, the bottom end of the support column is fixedly provided on the upper end of the suction cup, and the support column has a certain height.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model provides a lifting device for conveying large metal parts. When it is necessary to convey and lift the steel plate, multiple suction cups at the lower end of the magnetic lifting device body are moved to the upper end of the steel plate, and then power is turned on. The suction cups adsorb the steel plate due to magnetic force, and then the first insertion rod is manually moved outward and the first spring is stretched, so that the end of the first insertion rod leaves the first hole, and then the rectangular box is rotated to a proper angle, and then the second insertion rod is manually moved outward and the second spring is stretched, so that the end of the second insertion rod leaves the second hole, and then the telescopic plate is pulled outward from the rectangular box or pushed inward, so that the hook can stably hook the outer edge of the steel plate, and then the second insertion rod is released. Insert the rod, and under the pull of the second spring to restore the deformation, the second rod is reset and the end is inserted into the corresponding second hole, so that the telescopic plate is fixed in position relative to the rectangular box. Then release the first rod, and under the pull of the first spring to restore the deformation, the first rod is reset and the end is inserted into the corresponding first hole, so that the rectangular box is fixed in position relative to the suction cup. Repeat the above operation, fix all the hooks, and evenly hook both sides of the steel plate. Finally, the suction cup moves and lifts the steel plate. If the power is cut off and the suction cup loses its magnetic force, the steel plate falls down, but is hooked by the hook to avoid falling to the ground and causing damage to on-site facilities, while protecting personal safety. The purpose of this design is to further fix the two sides of the steel plate by adding adjustable hooks on both sides of multiple suction cups, so as to avoid the steel plate falling due to loss of magnetism of the suction cup, and protect on-site facilities and the personal safety of workers.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to solve the problem of how to stabilize the lifting technology, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0021] A sling for conveying large metal parts includes a magnetic sling body 1 and multiple suction cups 2. U-shaped plates 4 are symmetrically arranged on both sides of the upper end of the suction cup 2. A rotating disk 5 is rotatably arranged on the inner side of the U-shaped plate 4. A plurality of evenly distributed first holes 7 are opened on the circumferential side of the rotating disk 5. A first insertion rod 8 is movably arranged in the side wall of the U-shaped plate 4. A first spring 10 is sleeved on the outer side of the first insertion rod 8. A rectangular box 11 is fixed on the outer circumference of the rotating disk 5. A telescopic plate 12 is movably arranged in the rectangular box 11. A plurality of evenly distributed second holes 14 are opened inside the telescopic plate 12 along the length direction. A second insertion rod 15 is movably arranged in the side wall of the open end of the rectangular box 11. A second spring 17 is sleeved on the outer side of the second insertion rod 15. A hook 13 is fixed on the end of the telescopic plate 12.

[0022] Specifically, when it is necessary to transport and hoist the steel plate, the multiple suction cups 2 at the lower end of the magnetic hoist body 1 are moved to the upper end of the steel plate, and then power is turned on. The suction cup 2 adsorbs the steel plate due to magnetic force, and then the first plug rod 8 is manually moved outward and the first spring 10 is stretched, so that the end of the first plug rod 8 leaves the first hole 7, and then the rectangular box 11 is rotated to a proper angle, and then the second plug rod 15 is manually moved outward and the second spring 17 is stretched, so that the end of the second plug rod 15 leaves the second hole 14, and then the telescopic plate 12 is pulled outward from the rectangular box 11 or pushed inward, so that the hook 13 can stably hook the outer edge of the steel plate, and then the second plug rod 15 is released, and the second spring 17 restores the deformation and pulls the second rod 15 back to its original position and inserts its end into the corresponding second hole 14, so that the telescopic plate 12 is fixed relative to the rectangular box 11. Then, the first rod 8 is released. Under the deformation restoration pull of the first spring 10, the first rod 8 is restored and its end is inserted into the corresponding first hole 7, so that the rectangular box 11 is fixed relative to the suction cup 2. Repeat the above operation, fix all the hooks 13, and evenly hook both sides of the steel plate. Finally, the suction cup 2 moves and lifts the steel plate. If the power is cut off and the suction cup 2 loses its magnetic force, the steel plate falls down, but is hooked by the hook 13 to prevent it from falling to the ground and causing damage to the on-site facilities, while protecting personal safety. The purpose of this design is to further fix the two sides of the steel plate by adding adjustable hooks 13 on both sides of multiple suction cups 2, so as to prevent the steel plate from falling due to loss of magnetism of the suction cup 2, and protect on-site facilities and the personal safety of workers.

[0023] Further, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:

[0024] A rotating shaft 6 is fixedly installed in the middle of the rotating disk 5. The outer sides of the rotating shaft 6 are rotatably connected to the side walls of the U-shaped plate 4 through bearings. The purpose of this design is to ensure that the rectangular box 11 can rotate relative to the U-shaped plate 4 following the rotating disk 5.

[0025] Further, such as Figure 1-3 As shown, the following preferred technical solutions are provided:

[0026] The first insertion rod 8 is slidably connected to the side wall of the U-shaped plate 4, and a first handle 9 is fixed to the end of the first insertion rod 8. The first spring 10 is tightly connected between the outer side of the U-shaped plate 4 and the first handle 9. The first spring 10 drives the first insertion rod 8 away from the first handle 9 and engages with the first hole 7. The purpose of this design is to fix the position of the rotating disk 5 by inserting the first insertion rod 8 into the first hole 7, that is, to fix the rotation position of the rectangular box 11.

[0027] Further, such as Figure 1 and Figure 4 As shown, the following preferred technical solutions are provided:

[0028] The outer side of the telescopic plate 12 is slidably connected to the inner side of the rectangular box 11 , and the telescopic plate 12 matches the inner side of the rectangular box 11 in size. The purpose of this design is to change the position of the hook 13 by extending and retracting the telescopic plate 12 .

[0029] Further, such as Figure 1 and Figure 4 As shown, the following preferred technical solutions are provided:

[0030] The second insertion rod 15 is slidably connected to the side wall of the open end of the rectangular box 11, and a second handle 16 is fixed to the end of the second insertion rod 15. The second spring 17 is tightly connected between the rectangular box 11 and the second handle 16. The second spring 17 drives the second insertion rod 15 away from the end of the second handle 16 to engage with the second hole 14. The purpose of this design is to fix the position of the telescopic plate 12 by inserting the second insertion rod 15 into the second hole 14.

[0031] Further, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0032] A support column 3 is fixed in the middle of the bottom end of the U-shaped plate 4, and the bottom end of the support column 3 is fixed to the upper end of the suction cup 2. The support column 3 has a certain height. The purpose of this design is to support and fix the U-shaped plate 4. The support column 3 has a certain height so that the hook 13 can better hang on both sides of the steel plate.

[0033] To sum up: when it is necessary to transport and hoist the steel plate, the multiple suction cups 2 at the lower end of the magnetic lifter body 1 are moved to the upper end of the steel plate, and then power is turned on. The suction cup 2 adsorbs the steel plate due to magnetic force, and then the first plug rod 8 is manually moved outward and the first spring 10 is stretched, so that the end of the first plug rod 8 leaves the first hole 7, and then the rectangular box 11 is rotated to a proper angle, and then the second plug rod 15 is manually moved outward and the second spring 17 is stretched, so that the end of the second plug rod 15 leaves the second hole 14, and then the telescopic plate 12 is pulled outward from the rectangular box 11 or pushed inward, so that the hook 13 can stably hook the outer edge of the steel plate, and then the second plug rod 15 is released, and the second spring 17 restores the deformation and pulls the second rod 15 back to its original position and inserts its end into the corresponding second hole 14, so that the telescopic plate 12 is fixed relative to the rectangular box 11. Then, the first rod 8 is released. Under the deformation restoration pull of the first spring 10, the first rod 8 is restored and its end is inserted into the corresponding first hole 7, so that the rectangular box 11 is fixed relative to the suction cup 2. Repeat the above operation, fix all the hooks 13, and evenly hook both sides of the steel plate. Finally, the suction cup 2 moves and lifts the steel plate. If the power is cut off and the suction cup 2 loses its magnetic force, the steel plate falls down, but is hooked by the hook 13 to prevent it from falling to the ground and causing damage to the on-site facilities, while protecting personal safety. The purpose of this design is to further fix the two sides of the steel plate by adding adjustable hooks 13 on both sides of multiple suction cups 2, so as to prevent the steel plate from falling due to loss of magnetism of the suction cup 2, and protect on-site facilities and the personal safety of workers.
