Description

Technical Field

[0001] The invention relates to a sling, in particular to a sling used for a hard super-large plate of copper pipe. Background Art

[0002] In precision seamless copper pipe manufacturers, the finished coils formed by the rewinding machine are generally unloaded and transported using internal or external lifting equipment. The general rewinding coil lifting equipment consists of components such as a lifting rod, a swing arm, a positioning plate, a support plate, and a connecting rod. However, the production method of rigid oversized coils is different from that of rewinding machines, and traditional rewinding coil lifting equipment cannot be used for rigid oversized coils. Currently, oversized coils are transported by lifting or shoveling after rewinding. Before rewinding, special heat-resistant plates, split pallets, liners, and even transport transfer racks are placed at the bottom of the coil. This is not conducive to the stability of the high-speed rotation of the coil and increases the labor intensity of the operator. It is very inconvenient and costly, so a new method is needed to solve the above problems. Summary of the Invention

[0003] In order to overcome the above-mentioned defects, the present invention provides a rigid super-large coil sling, in which the upper surface of the long tongue plate is used to directly contact the bottom surface of the coil. Since the two have sufficient contact area and the special long tongue plate surface material is used, deformation of the pipe at the contact point can be avoided, thereby simplifying the operation process and improving work efficiency.

[0004] The technical solution adopted by the present invention to solve its technical problems is:

[0005] A rigid super-large disk sling comprises a supporting member, a lining plate and a plurality of supporting units, wherein the supporting unit comprises a turntable, a long tongue plate and a driving assembly, the supporting member is fixedly connected to the lining plate, a cavity is provided inside the lining plate, the turntable is rotatably mounted on the lining plate, the long tongue plate is slidably mounted on the lining plate, the driving assembly is connected to the turntable, and when the driving assembly drives the turntable to rotate, the turntable can drive the long tongue plate to extend out of the cavity of the lining plate or retract the lining plate.

[0006] Preferably, the four sides of the supporting member protrude outward to form a plurality of connecting members, and the connecting members are fixedly connected to the lining plate through support rods, and a fixing block is also fixed on the support rod between the supporting member and the lining plate.

[0007] Preferably, the driving component is a driving cylinder, which is horizontally arranged on the lining plate, and one end of the driving cylinder is fixedly mounted on the fixed block, and the piston rod thereof is fixedly connected to the turntable.

[0008] Preferably, the turntable is horizontally arranged on the upper surface of the lining plate, and one end of the turntable is rotatably connected to the lining plate through a rotating shaft, and the other end is provided with a strip groove.

[0009] Preferably, a limiting groove is provided on the lining plate, and a sliding groove is provided on the lower surface of the lining plate, and the limiting groove and the sliding groove are opened in the same direction.

[0010] Preferably, the long tongue plate is slidably installed in the sliding groove on the lower surface of the lining plate through a slider, and a push column is also fixed on the long tongue plate, and the push column is placed in the limiting groove of the lining plate and the strip groove of the turntable.

[0011] The beneficial effects of the present invention are as follows: the present invention includes a supporting part, a lining plate and a plurality of supporting units, wherein the supporting unit includes a turntable, a long tongue plate and a driving cylinder. During operation, the driving cylinder drives the turntable to rotate, the turntable drives the push column to move, the push column drives the long tongue plate to extend, and the long tongue plate supports the oversized disk. When using this sling, the hard oversized disk needs to be rolled up on the slotted pallet, and there is no need to place a heat-resistant pad between the pallet and the oversized disk. After the rolling is completed, the long tongue plate in the sling is extended into the slotted notch of the pallet to support the bottom of the disk. The upper surface of the long tongue plate directly contacts the bottom surface of the coil. Because of the sufficient contact area and the special long tongue plate surface material, the deformation of the tube at the contact point can be avoided. Therefore, when using the present invention to lift oversized discs, there is no need to place heat-resistant plates, split pallets, lining plates or even transport transfer racks before winding. It is only necessary to arrange a slotted pallet on the winding table, and use the long tongue plate to enter the slot to directly contact the hard oversized disc for lifting. The present invention is easy to operate, simplifies the operating process and greatly improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example: Figure 1 and Figure 2As shown, a rigid super-large disk sling includes a supporting member 10, a lining plate 40 and a plurality of supporting units, wherein the supporting unit includes a turntable 20, a long tongue plate 30 and a driving assembly, the supporting member 10 is fixedly connected to the lining plate 40, a cavity is opened inside the lining plate 40, the turntable 20 is rotatably mounted on the lining plate 40, the long tongue plate 30 is slidably mounted on the lining plate 40, the driving assembly is connected to the turntable, and when the driving assembly drives the turntable to rotate, the turntable 20 can drive the long tongue plate 30 to extend out of the cavity of the lining plate or retract the lining plate. The lining plate 40 is located below the supporting member 10. The middle part of the lining plate is a cavity. Usually, the long tongue plate 30 is retracted into the lining plate. During operation, the external equipment lifts the supporting member 10 and sets the sling on the hard oversized disk, that is, the hard oversized disk is placed in the cavity of the lining plate. The driving assembly is started, and the driving assembly drives the turntable 20 to rotate. When the turntable rotates, it drives the long tongue plate 30 to extend from the bottom of the lining plate to support the hard oversized disk. In this embodiment, four groups of support units are provided, that is, the hard oversized disk is supported by four groups of long tongue plates 30. When using this sling, the hard oversized disk needs to be rolled onto the slotted pallet. There is no need to prevent heat-resistant pads between the pallet and the oversized disk. After rolling is completed, the long tongue plate in this sling is extended into the slotted notch of the pallet to support the bottom of the disk. The upper surface of the long tongue plate directly contacts the bottom surface of the coil. Because of the sufficient contact area and the special long tongue plate surface material, deformation of the tube at the contact point can be avoided. Therefore, when using the present invention to lift oversized disks, there is no need to place heat-resistant plates, split pallets, lining plates or even transport transfer racks before winding. It is only necessary to arrange a slotted pallet on the winding table and use the long tongue plate to enter the slot to directly contact the hard oversized disk for lifting. The present invention is easy to operate, simplifies the operating process, and greatly improves production efficiency.

[0019] like Figure 1 As shown, the four sides of the hanging member 10 protrude outward to form a plurality of connecting members 11, which are fixedly connected to the lining plate 40 via support rods 12. A fixing block 13 is also fixed to the support rod between the hanging member 10 and the lining plate 40. The hanging member 10 is cylindrical in shape, with four connecting members 11 evenly distributed around it. The lining plate 40 is annular in structure. The upper end of the support rod 12 is fixedly connected to the connecting member 11, and the lower end is fixedly connected to the lining plate 40. The hanging member and the lining plate are arranged parallel to each other, and the fixing block 13 is located close to the lining plate 40.

[0020] The driving assembly is a driving cylinder 50, which is horizontally arranged on the lining plate 40, and one end of the driving cylinder is fixedly mounted on the fixing block 13, and its piston rod 51 is fixedly connected to the turntable 20. Therefore, when the piston rod of the driving cylinder is extended or retracted, it can drive the turntable 20 to rotate.

The long tongue plate 30 is also fixed with a push post 31, which is placed in the limit groove 41 of the lining plate and the strip groove 21 of the turntable. When the piston rod 51 of the driving cylinder is extended, it drives the turntable 20 to rotate toward the inner side of the lining, that is, its cavity side, and the turntable drives the push column 31 to run along the limit groove 41 toward the inner side of the lining, and the push column 31 drives the long tongue plate 30 to extend out of the inner cavity of the lining; correspondingly, when the piston rod 51 of the driving cylinder is retracted, it drives the long tongue plate 30 to retract under the lining.

[0022] The operation process of the present invention is as follows: during operation, the external equipment lifts the lifting piece 10 and sets the lifting device on the hard oversized disk, that is, the hard oversized disk is placed in the cavity of the lining plate, and the driving cylinder 50 is started. The driving cylinder drives the turntable 20 to rotate, and the turntable drives the pushing column 31 to run along the limiting groove 41 toward the inner side of the lining plate. The pushing column 31 drives the long tongue plate 30 to extend out of the inner cavity of the lining plate, and the long tongue plate 30 extends from the bottom of the lining plate to support the hard oversized disk.

[0023] It should be noted that those skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
