[0025] Please combine Figure 1 As shown, in the use process, before installing the iron tower, first bury the bottom end of base 3 in the ground, then fix the iron tower on the top surface of tower base 1 for wiring support of the cable, when the local section collapses and causes the inclination of base 3, the inclination of base 3 makes the inclination of protrusion 5, the inclination of protrusion 5 makes the inclination of support frame 2, the inclination of support frame 2 makes the inclination of tower base 1 and the iron tower, when the inclination of tower base 1 needs to be leveled, the staff opens the door hinged on the side end of base 3, loosens the locking assembly, then simultaneously operates the jack 14 below the inclination direction and the jack 14 opposite to it, the output end of the jack 14 below the inclination direction pushes U-shaped plate 15 to move upwards, so that the inner bottom surface of U-shaped plate 15 gradually fits with the bottom surface of arc plate 13 and pushes arc plate 13 to rotate and move upwards, arc plate 13 drives support frame 2 to rotate upwards, the output end of the jack 14 opposite to it gradually shortens, the output end of jack 14 drives the fixed U-shaped plate 15 to move downwards, U-shaped plate 15 drives arc plate 13 to rotate downwards, arc plate 13 drives support frame 2 to rotate, support frame 2 drives positioning rod 4 to rotate, the setting of multiple positioning rods 4 plays a limiting role to prevent the horizontal rotation of support frame 2, support frame 2 drives tower base 1 to rotate, support frame 2 drives tower base 1 to rotate gradually and level, when tower base 1 is leveled, tighten the locking assembly, the locking assembly fixes support frame 2 and protrusion 5, so that support frame 2 cannot rotate, support frame 2 cannot rotate, so that tower base 1 cannot rotate, improve the stability of tower base 1, reduce the collapse phenomenon of long-time inclination of tower base 1, thereby prevent the cable from being pulled off.

[0026] The spherical surface of the protrusion 5 does not contact the surface of the base 3, and the horizontal plane where the center of the spherical surface is located divides the transverse plate of the support frame 2, so that the protrusion 5 clamps the support frame 2, and the support frame 2 can only rotate on the protrusion 5 and cannot slide longitudinally on the protrusion 5, thereby improving the stability of the support frame 2 and the stability of the tower base 1.

[0027] The surface of the positioning rod 4 in contact with the inner wall of the cavity of the base 3 is an arc surface, and the center of the circle where the arc surface is located is in the same horizontal plane as the center of the sphere where the protrusion 5 is located, so that the positioning rod 4 can rotate in the cavity of the base 3 and prevent the positioning rod 4 from being squeezed against the inner wall of the base 3 during rotation.

[0028] The locking assembly includes a plurality of dovetail grooves 7 formed in the top surface of the transverse plate of the support frame 2, a dovetail block 8 slidingly fitted in the dovetail groove 7, a second brake pad 10 fixedly connected to the top surface of the dovetail block 8, a first brake pad 6 abuttingly arranged on the side wall of the second brake pad 10, the first brake pad 6 being fixedly embedded in the outer wall of the protrusion 5, the first brake pad 6 being arc-shaped and the center of the circle where the arc-shaped surface is located coinciding with the center of the sphere of the protrusion 5, a compression spring 9 fixedly connected to the side wall of the dovetail block 8 and arranged in the dovetail groove 7, a plurality of limiting rods 11 fixedly connected to the top surface of the transverse plate of the second brake pad 10, and a clamp 12 slidingly arranged between the limiting rods 11 and sleeved on the protrusion 5 and abuttingly arranged on the vertical side wall of the second brake pad 10.

[0029] Please refer to Figure 1 When it is necessary to level the tower base 1, the worker first loosens the clamp 12, at which time the compression spring 9 pushes the dovetail block 8 to move, the dovetail block 8 drives the second brake pad 10 to move and separate from the first brake pad 6, the first brake pad 6 cancels the limitation of the second brake pad 10 so that the second brake pad 10 can rotate, and then leveling operation is performed, the output end of the jack 14 indirectly drives the support frame 2 to rotate, the support frame 2 drives the dovetail block 8 to rotate, the dovetail block 8 drives the second brake pad 10 to rotate, the second brake pad 10 drives the clamp 12 to rotate, and the plurality of limiting rods 11 limit the clamp 12 to prevent the clamp 12 from sliding off the second brake pad 10, and when the tower base 1 is leveled, the worker gradually tightens the clamp 12, the clamp 12 drives the second brake pad 10 to move and gradually abut against the surface of the first brake pad 6, thereby realizing the limitation of the first brake pad 6 to the second brake pad 10.

[0030] The surface of the second brake pad 10 in contact with the first brake pad 6 is an arc surface, and the center of the circle where the arc surface is located coincides with the center of the sphere of the protrusion 5, thereby increasing the contact area of the second brake pad 10 with the first brake pad 6 and the friction force between the second brake pad 10 and the first brake pad 6, and facilitating the limitation of the first brake pad 6 to the second brake pad 10.
