[0017] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] like Figure 1 It is a structural schematic diagram of the utility model, a steel coil gripper unit, the center of the steel coil has a cavity, the gripper unit includes a frame 1, a hook 2 and an outer fixing component 3, the hook 2 is fixedly connected to the frame 1, the hook 2 is used to extend into the cavity in the center of the steel coil, the outer fixing component 3 is fixedly connected to the frame 1, the outer fixing component 3 is used to resist the outside of the steel coil, through the design of the outer fixing component 3 and with the cooperation of the hook, the fixation of the steel coil is increased, thereby providing safety for the steel coil during movement and avoiding accidental falling of the steel coil.

[0019] Two outer fixing components 3 are arranged on the frame 1 in the present application, and the hooking member 2 is located between the two outer fixing components 3, so that the steel coil is fixed more firmly. For the outer fixing component 3, at least one is provided in the present application, and multiple ones may be provided, and the present application does not make any specific limitation on this.

[0020] The outer fixing assembly 3 includes a mounting frame 31, a driving member 32 and an abutment block 33. The mounting frame 31 is fixedly connected to the frame 1, and the fixed connection method can be welding or bolt fixing connection. The driving member 32 is fixedly connected to the mounting frame 31, and the output end of the driving member 32 is transmission-connected to the abutment block 33. The abutment block 33 is used to abut the outer periphery of the steel coil. The driving member 32 is used to provide power for the abutment block 33 to approach or move away from the steel coil. The moving direction of the abutment block 33 is the radial direction of the steel coil. The driving member 32 can be a hydraulic cylinder, or a telescopic element such as an electric push rod, so as to provide power for the abutment block 33. This application does not make any specific limitation on this.

[0021] like Figure 1 , Figure 2 As shown, an end face fixing portion 331 is protruded on the front end of the abutment block 33, and the end face fixing portion 331 is used to abut the end face of the steel coil. Under the cooperation of the end face fixing portion 331 located at the front section of the abutment block 33 and the hooking member 2, the axial restriction of the steel coil is completed, thereby preventing the steel coil from slipping off the hooking member 2.

[0022] like Figure 1 , Figure 2 As shown, end face fixing portions 331 are protruded on both ends of the abutment block 33. The two end face fixing portions 331 restrict the steel coil between them. The axial restriction of the steel coil is completed by the end face fixing portions 331 at both ends, thereby preventing the steel coil from slipping off the hook member 2. The spacing between the end face fixing portions 331 at both ends is greater than the axial length of the steel coil.

[0023] A guide post 332 is arranged on the abutment block 33 , and the guide post 332 is slidably connected to the mounting frame 31 , thereby increasing the stability of the movement of the abutment block 33 .

[0024] When in use, the frame 1 is connected to the transfer device, and the transfer device drives the gripper unit to move its position so that the hooking part of the hooking member 2 extends into the cavity in the center of the steel coil, and then the driving member 32 is started, so that the abutment block 33 approaches the steel coil until it abuts against the outer periphery of the steel coil. At this time, the end fixing part located at the end further completes the axial restriction of the steel coil, and the transfer device is started again to drive the transfer of the steel coil, thereby completing the grabbing and transportation of the steel coil.

[0025] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
