Example

[0024] like Figures 2 to 3 As shown, a symmetrically arranged screw rod 7 is provided on the side of the metal bending part 5 away from the winding barrel 1, and two groups of screw rods 7 penetrate the connecting plate 4 and extend into the PE pad 3. A nut 8 is provided on the end of the PE pad 3 close to the winding barrel 1, and an arc treatment is performed on the end of the PE pad 3 close to the winding barrel 1. An anti-corrosion coating is provided on the surface of the PE pad 3. A through hole 9 is provided on the upper half of the metal bending part 5, and a matching annular ferrule 10 is provided in the through hole 9. A wear-resistant ring is provided on the inner annular surface of the annular ferrule 10. A reinforcing rib is provided on the bent part of the metal bending part 5. Any group of screw rods 7 and the metal A fixing nut 11 is provided at the joint of the metal bending part 5, an annular groove 12 is provided on the metal bending part 5, and a symmetrically arranged gasket 13 is provided in the annular groove 12.

[0025] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0026] In actual application, the connection relationship between the metal bending part 5 and the winding barrel 1 is realized through the PE pad 3 and the connecting plate 4, and the fitting problem is solved by making an arc treatment at the connection between the PE pad 3 and the winding barrel 1 to improve the stability. At the same time, when the fixing nut 11 is subjected to external impact or the fixing nut 11 itself shakes, the angle of the step-shaped protrusion 14 is greater than the angle between the thread on the screw 7 and the horizontal plane. Therefore, before the two sets of gaskets 13 achieve relative sliding, the fixing nut 11 cannot be separated from the screw 7, thereby improving the stability of the lifting ear and avoiding shaking during the lifting process to affect the use.

[0027] In summary, with the aid of the above-mentioned technical solution of the utility model, the strength of the lifting ear is increased by bending the top end of the metal bending part 5 and bending it toward the center of the winding barrel 1. At the same time, the screw 7 and the gasket 13 ensure that the PE pad 3, the connecting plate 4 and the metal bending part 5 are connected stably, reducing the possibility of shaking of the fixing nut 11, thereby reducing the occurrence of accidents, and the annular sleeve 10 is used to reduce the wear on the metal bending part 5 during use, thereby extending the service life.
