[0030] Example 1

[0031] See also Figure 1-Figure 3 In this embodiment, a lifting cover type lifting ear includes a connecting seat 20 fixedly connected to the base plate 10, the connecting seat 20 has a connecting hole 21 for the lifting mechanism to pass through, a clamping plate 22 is provided inside the connecting hole 21, a guide rod 23 is fixedly connected to the clamping plate 22 and passes through the connecting seat 20 and extends toward the base plate 10, and a spring 24 is compressed between the guide rod 23 and the base plate 10.

[0032] This embodiment connects the base plate 10 to the tower and uses the thrust of the spring 23 to push the clamping plate 22 toward the inside of the connecting hole 21, which can clamp the lifting mechanism and reduce the shaking amplitude of the lifting mechanism in the connecting hole 21, thereby facilitating safe and efficient lifting of the tower.

[0033] Specifically, the base plate 10 is generally constructed in a disc shape, and a plurality of positioning holes 11 are provided on the periphery of the base plate 10 , and the positioning holes 11 are evenly distributed along the circumference of the base plate 10 . The base plate 10 can be fixedly connected to the tower by sequentially passing bolts through the positioning holes 11 on the base plate 10 and the tower.

[0034] In addition, the connecting seat 20 is integrally fixed to the center of the substrate 10. The connecting seat 20 is integrally constructed into a triangular shape with an arc-shaped top. The connecting hole 21 is formed at the top of the connecting seat 20, and the axis of the connecting hole 21 is perpendicular to the axis of the substrate 10. In order to further improve the structural strength, a reinforcing plate 12 is provided between the connecting seat 20 and the substrate 10, and the reinforcing plate 12 is integrally arranged vertically with the substrate 10. The reinforcing plate 12 is symmetrically arranged on both sides of the connecting seat 20. At the same time, the reinforcing plate 12 is also symmetrically arranged on both sides of the connecting hole 21.

[0035] In addition, the clamping plate 22 is constructed as an arc-shaped plate as a whole, and the clamping plate 22 is arranged as a whole along the axial direction of the connecting hole 21. The guide rod 23 is arranged as a whole to remain parallel to the axis of the base plate 10. The guide rod 23 is symmetrically arranged at both ends of the clamping plate 22. A mounting hole 25 is opened at the lower end of the guide rod 23. The mounting hole 25 extends as a whole along the axial direction of the guide rod 23, and the upper part of the spring 24 is passed through the interior of the mounting hole 25.

[0036] When in use, first connect the base plate 10 to the tower through the positioning hole 11, and then pass the lifting mechanism (such as a lifting rod) through the connecting hole 21. Since the spring 24 is in a compressed state, the clamping plate 22 will be pressed against the surface of the lifting mechanism under the push of the spring 24, thereby limiting the lifting mechanism to a certain extent, avoiding the lifting mechanism from shaking significantly inside the connecting hole 21, and finally use the lifting equipment to complete the lifting of the tower.

[0037] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
