Description

Technical Field

[0001] The utility model relates to the field of hoisting clamps, in particular to a hoisting clamp for an electroplated wire coil. Background Art

[0002] The metal wire is coated with other metals on the surface through electrochemical reaction to enhance the corrosion resistance and wear resistance of the wire and extend the service life of the product. The electroplated wire is rolled on the reel for easy transportation and use. The wire roll is relatively heavy and requires the use of lifting claws when transporting.

[0003] Existing electroplated wire coil lifting clamps, for example, the elastic lifting clamp for enameled wire proposed in patent application number "CN201921681876.1", uses structures such as a claw arm, a first claw hook, a second claw hook, a wire rope, a connecting rod, etc., and utilizes the hinge between the connecting rods to tighten the lifting clamp, while utilizing the groove at the bottom of the lifting clamp to make the lifting clamp structure more stable.

[0004] However, the sizes of the first claw hook and the second claw hook are fixed. When used for thicker wire coils, the sizes of the first claw hook and the second claw hook are small and cannot clamp the wire coil. The size of the claw hook cannot be adjusted according to the thickness of the wire winding. The applicable size range of the lifting clamp is small. Therefore, a lifting clamp for electroplated wire coils is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A clamp for hoisting a coil of electroplated wire, such as Figure 1-Figure 4 As shown, it includes a lifting plate 1, on which a lifting ring for lifting is fixedly connected, and the lifting plate 1 is provided with a plurality of groups of rectangular grooves 3, in which the plurality of groups of rectangular grooves 3 are rotatably connected with clamping claw assemblies, and the plurality of groups of clamping claw assemblies are arranged in a circular array, and the clamping claw assembly includes a claw arm 4, one end of the claw arm 4 is rotatably connected in the rectangular groove 3, and the other end is provided with an adjusting port 5, in which a claw head 6 is clamped, and a locking arm 7 is clamped between one end of the claw head 6 and the claw arm 4.

[0025] The distance from one end of the claw head 6 close to the center of the lifting plate 1 to the claw arm 4 is of limited length. By adjusting the position of the claw head 6 in the rectangular groove 3 and fixing it, the effective length of the claw head 6 is changed, and the size of the clamping jaw assembly is adjusted. The rectangular groove 3 reserves a travel space for the opening and closing of the claw arm 4 during grasping. By controlling the rotation of multiple groups of claw arms 4, multiple groups of clamping jaw assemblies are opened and closed, and multiple groups of claw heads 6 can be clamped for electroplating wire coils. Thicker wire coils can be used for lifting. The size of the clamping jaw assembly is adjusted according to the thickness of the wire winding, and the lifting clamp has a wide range of applicable sizes.

[0026] The side wall of the claw head 6 is penetrated by a plurality of adjustment holes 9 , the adjustment holes 9 penetrate the claw arm 4 , the claw arm 4 is penetrated and connected with a second screw rod 13 , and the second screw rod 13 penetrates the adjustment hole 9 on the claw head 6 .

[0027] like Figure 1-Figure 3 As shown, the second screw rod 13 is removed, the claw head 6 is slid, the adjustment hole 9 aligned between the claw arm 4 and the claw head 6 is changed, and the second screw rod 13 is installed again, thereby adjusting the effective length of the claw head 6.

[0028] One end of the locking arm 7 is rotatably connected to the claw head 6. The locking arm 7 is located on the side of the claw arm 4 away from the center of the hanging plate 1. The other end of the locking arm 7 is penetrated by a screw 12. The side wall of the claw arm 4 is penetrated by multiple groups of locking holes 8, and the screw 12 penetrates the locking hole 8.

[0029] like Figure 1-Figure 4 As shown, when the effective length of the claw head 6 is adjusted, the locking arm 7 is rotated so that the locking arm 7 is connected to the locking hole 8 of the claw arm 4 through the screw 12, so that the claw arm 4, the claw head 6 and the locking arm 7 form a triangle, thereby increasing the structural stability between the claw head 6 and the claw arm 4.

[0030] The side wall of the lifting plate 1 is fixedly connected with multiple groups of protrusions 14, which correspond to multiple groups of clamping claw assemblies respectively. The upper ends of the multiple groups of claw arms 4 are all fixedly connected with driving arms 17 at an angle, and driving assemblies are fixedly connected between the multiple groups of driving arms 17 and the multiple groups of protrusions 14.

[0031] like Figure 1 As shown, the protrusion 14 increases the distance between the driving assembly base and the rectangular groove 3, making it easier for the driving assembly to drive the driving arm 17 to rotate, and the driving arm 17 drives the claw arm 4 to rotate.

[0032] The driving assembly includes a rotating seat 15, which is fixed to the upper end of the protrusion 14. Hydraulic cylinders 16 are rotatably connected in multiple groups of rotating seats 15. Fixed seats 18 are fixed to one side of multiple groups of driving arms 17. Output ends of multiple groups of hydraulic cylinders 16 are rotatably connected to multiple groups of fixed seats 18 respectively.

[0033] like Figure 1-Figure 2 As shown, the hydraulic cylinder 16 (model HSG125) pushes and pulls the drive arm 17, driving the claw arm 4 to rotate, so that the clamping claw assembly opens and closes.

[0034] One end of the claw head 6 is sleeved with a protective sleeve 11, the upper end of the protective sleeve 11 is fixedly connected with a protective pad 10, the protective pad 10 is attached to the upper end of the claw head 6, and a protective pad 2 19 is glued to one side of the claw arm 4 close to the center of the hanging plate 1.

[0035] like Figure 1-Figure 4 As shown, the wire coil is protected during hoisting by protective pad 10 and protective pad 2 19 to prevent the wire coil from being crushed by the claw head 6 or the claw arm 4 during hoisting, and the protective sleeve 11 facilitates the installation of protective pad 10.

[0036] The working principle of the electroplated wire coil hoisting clamp provided by the utility model is as follows:

[0037] By adjusting the effective length of the claw head 6, using the locking arm 7 to lock the claw head 6 and the claw arm 4 structure, the hydraulic cylinder 16 pushes and pulls the drive arm 17 to rotate the claw arm 4, and the claw head 6 clamps the electroplated wire roll for hoisting. It can be used for hoisting thicker wire rolls. The size of the clamping jaw assembly is adjusted according to the thickness of the wire winding, and the hoisting clamping jaw has a wide range of applicable sizes.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
