Description

Technical Field

[0001] The utility model relates to the technical field of steel coil standing clamps, in particular to a steel coil double-sided standing clamp. Background Art

[0002] Double-sided coil clamp is a lifting tool specially used for lifting steel coils in an upright state.

[0003] The existing technology mostly adopts the intelligent double-arm vertical steel coil clamp disclosed in the announcement number CN211769809U, which includes a clamp body, a lock hook locking detection sensor for detecting the locking state of the swing hook and the fixed hook is provided on the right pull rod or the left pull rod on the back side of the swing hook relative to the lock hook side of the fixed hook, and a contact clamping detection device for detecting the contact and clamping state between the clamp body and the vertical steel coil and a lifting mechanism for touching the contact clamping detection device are provided on the support plate. However, the above technology still has problems in use due to structural limitations:

[0004] The existing double-sided coil clamps are divided into automatic and mechanical types. Both of them perform double clamping of the steel coil by outer clamping claws and inner clamping claws. When using the mechanical double-sided coil clamp, the outer clamping claws must first be initially clamped with the outer arc surface of the steel coil before the double-sided coil clamp can be pulled upward to allow the outer clamping claws and inner clamping claws to tightly clamp the steel coil. After the mechanical double-sided coil clamp is placed on the steel coil, the two outer clamping claws are in an initial state. At this time, the distance between the two outer clamping claws is relatively fixed. Therefore, when facing steel coils of different specifications, the two outer clamping claws cannot perform initial clamping of steel coils of different specifications, which leads to the failure of the clamping operation of the mechanical double-sided coil clamp.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5 A steel coil double-sided vertical coil clamp, comprising a vertical pull rod 1, as shown in the attached Figure 1As shown, a lifting rod can be provided at the upper end of the vertical pull rod 1, and the lifting rod is used to connect with the lifting equipment. The vertical pull rod 1 is provided with a first outer clamping claw 2, a second outer clamping claw 3, a first rotating shaft 4 and a second rotating shaft 5. The two first outer clamping claws 2 and the two second outer clamping claws 3 are respectively provided on the outer and inner sides of the vertical pull rod 1. The first rotating shaft 4 is fixedly connected to the middle of the two second outer clamping claws 3, and the second rotating shaft 5 is fixedly connected to the middle of the two first outer clamping claws 2.

[0025] The middle-end mounting block 6, the inner clamping claw 7 and the movable clamping block 8, the middle-end mounting block 6 is rotatably connected to the first rotating shaft 4 and the second rotating shaft 5, the two inner clamping claws 7 are respectively fixedly connected to the upper ends of the two first outer clamping claws 2 and the upper ends of the two second outer clamping claws 3, when the steel coil monomer is clamped, the inner clamping claw 7 is located on the inner arc surface of the steel coil monomer, the first outer clamping claw 2 and the second outer clamping claw 3 are located on the outer arc surface of the steel coil monomer, the lower end of the middle-end mounting block 6 is against the upper end of the steel coil monomer, and the two groups of movable clamping blocks 8 are separated. They are respectively arranged at the lower ends of the two first outer clamping claws 2 and the lower ends of the two second outer clamping claws 3, and the two groups of mobile clamping blocks 8 are abutted against the outer arc surface of the steel coil monomer to preliminarily clamp the outer arc surface of the steel coil monomer of different specifications, and then the vertical pull rod 1 is pulled upward to make the lower ends of the two first outer clamping claws 2 and the lower ends of the two second outer clamping claws 3 relatively close and deflected, so that the two groups of mobile clamping blocks 8 and the two inner clamping claws 7 respectively clamp the outer arc surface and the inner arc surface of the steel coil monomer tightly, thereby completing the clamping of the steel coil monomer.

[0026] The lower end of the vertical pull rod 1 is fixedly connected to a mounting shaft 9, and both ends of the mounting shaft 9 extend to the outer end of the vertical pull rod 1. The extended ends of the two ends of the mounting shaft 9 are respectively rotatably connected to two first connecting rods 10. The mounting shaft 9 is located on the inner side of the vertical pull rod 1 and is rotatably connected to two second connecting rods 11. The lower ends of the two first connecting rods 10 are rotatably installed with a first rotating shaft 12, and the two first outer clamping claws 2 are respectively fixedly connected to the two ends of the first rotating shaft 12, and the lower ends of the two second connecting rods 11 are rotatably installed with a second rotating shaft 13. The two second outer clamping claws 3 are respectively fixedly connected to the two ends of the second rotating shaft 13. When the vertical pull rod 1 moves upward, the first outer clamping claw 2 and the second outer clamping claw 3 are respectively deflected with the second rotating shaft 5 and the first rotating shaft 4, and the upper and lower ends of the first outer clamping claw 2 and the second outer clamping claw 3 are deflected in opposite directions.

[0027] A through slot is provided at the middle end of the middle mounting block 6, and two inner clamping claws 7 extend to the lower end of the middle mounting block 6 through the through slot. When the first outer clamping claw 2 and the second outer clamping claw 3 are deflected, the two groups of mobile clamping blocks 8 and the two inner clamping claws 7 move simultaneously to double clamp the steel coil. The lower ends of the two first outer clamping claws 2 and the lower ends of the two second outer clamping claws 3 are fixedly connected with a horizontal long plate 14, in which a placement slot 15 is provided, and both sides of the horizontal long plate 14 are provided with a mobile long slot 16 connected to the placement slot 15.

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] First, connect the vertical tie rod 1 to the lifting equipment, and use the lifting equipment to move the vertical tie rod 1 to the top of the steel coil, and then move the vertical tie rod 1 downward, so that the inner clamping claw 7 is located at the inner arc surface of the steel coil, and the first outer clamping claw 2 and the second outer clamping claw 3 are located at the outer arc surface of the steel coil, and the lower end of the middle end mounting block 6 is against the upper end of the steel coil;

[0031] At this time, if attached Figure 1 and attached Figure 2 As shown, the push rod 18 is pulled toward the outer arc surface of the steel coil by hand, and the push rod 18 drives the movable long block 17 and the movable clamping single block 8 to move together. Since the two groups of movable clamping single blocks 8 are respectively movably arranged in the two movable long blocks 17, when the two groups of movable clamping single blocks 8 are against the outer arc surface of the steel coil, the movable clamping single blocks 8 in the two groups are squeezed by the outer arc surface of the steel coil, and they move in the movable long block 17 and fit with the outer arc surface of the steel coil, thereby preliminarily clamping the outer arc surface of the steel coil;

[0032] Then, the vertical rod 1 is pulled upward by the lifting equipment. Since the two sets of movable clamping blocks 8 initially clamp the outer arc surface of the steel coil, the middle-end mounting block 6 is stationary relative to the vertical rod 1, and the vertical rod 1 drives the first connecting rod 10 and the second connecting rod 11 to move upward through the mounting shaft 9. The first connecting rod 10 and the second connecting rod 11 respectively drive the upper end of the first outer clamping claw 2 and the upper end of the second outer clamping claw 3 to move upward through the first rotating shaft 12 and the second rotating shaft 13, so that the first outer clamping claw 2 and the second outer clamping claw 3 are deflected by the second rotating shaft 5 and the first rotating shaft 4 respectively.

[0033] The upper end of the first outer clamping claw 2 and the upper end of the second outer clamping claw 3 respectively drive the two inner clamping claws 7 to deflect upward, so that the two inner clamping claws 7 move away from each other and clamp against the inner arc surface of the steel coil unit. The lower end of the first outer clamping claw 2 and the lower end of the second outer clamping claw 3 respectively lead the two groups of mobile clamping blocks 8 to deflect downward, so that the two groups of mobile clamping blocks 8 are further tightly fitted with the outer arc surface of the steel coil unit, thereby lifting the steel coil unit.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
