detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Example 1:

As shown in Figure 2, an auxiliary pole-holding ball bearing at the top of a transmission line pole tower includes a node plate 1 and a fixed piece 2 fixed on the node plate 1, and the fixed piece 2 is provided with a ball socket base 21, so A ball socket is arranged on the ball socket base 21 , a ball head 3 is arranged in the ball socket, and a connecting piece 4 is arranged on the ball head 3 .

The gusset plate is directly installed on the top of the tower, and the connecting piece 4 is connected to the tower assembly equipment. During installation, the ball head can be directly placed in the ball socket, which avoids the problem of installing the existing support on the top of the tower, and avoids the problem caused by holes. Improper position makes it difficult to install hinge bolts, which are easy to assemble and disassemble. The ball head can deflect freely in the ball socket, its force is clear and its mechanical properties are good. The gusset plate can obtain the stable support of the tower body parts, and the stability of the system is good.
