Detailed Description
One embodiment of the supporting tool for the embedded pole in the invention is shown in fig. 3 and 4, and comprises a supporting plate 100 and a rotation stopping block 200 which are separately arranged, wherein the supporting plate 100 is in a semi-annular shape, and the rotation stopping block 200 is in a rectangular parallelepiped structure.
Referring to fig. 5, fig. 5 shows a state view of the embedded pole, when viewed from a bottom end surface thereof after being laid flat, the embedded pole includes an epoxy resin housing 600, and the epoxy resin housing 600 has an insulation pull rod through hole for passing through an insulation pull rod 700. Four insert bosses 601 are arranged on the bottom end face of the epoxy resin shell 600, a metal insert 602 is embedded in each insert boss 601, and the metal insert 602 is provided with a threaded hole so as to be convenient for mounting and fixing the solid-sealed polar pole.
The supporting plate 100 has an outer supporting wall 102 for supporting contact with the wall of the through hole of the insulating pull rod and an inner supporting wall 101 for supporting contact with the outer peripheral surface of the insulating pull rod 700, and both the outer supporting wall 102 and the inner supporting wall 101 are in a semi-circular arc shape.
The rotation stopping block 200 is used for being clamped between the two insert bosses 601, and the rotation stopping block 200 and the support plate 100 are detachably and fixedly connected together through two sets of fasteners. Specifically, each set of fasteners comprises a first bolt 400, a second bolt 300 and a washer assembly 500, wherein the first bolt 400 passes through the support plate 100 and the rotation stopping block 200, the washer assembly 500 is sleeved on the first bolt 400, and the washer assembly 500 comprises a flat washer and a spring washer. The shaft portion of the first bolt 400 is formed with a coaxial female screw hole, and the second bolt 300 is threadedly coupled with the female screw hole, thereby clamping and fixing the support plate 100 and the rotation stop block 200 together.
When the supporting tool for the solid-sealed polar pole is used, as shown in fig. 5, the solid-sealed polar pole is firstly horizontally placed on an operation platform, then the supporting plate 100 of the supporting tool is arranged in an insulating pull rod through hole of an epoxy resin shell 600, an outer supporting wall 102 of the supporting plate 100 is in supporting contact with the hole wall of the insulating pull rod through hole, meanwhile, the rotation stopping block 200 abuts against the bottom end face of the epoxy resin shell 600, and the rotation stopping block 200 is clamped between two insert bosses 601, so that the rotation stopping fit is formed between the rotation stopping block 200 and the epoxy resin shell 600, and the supporting plate 100 can be prevented from rotating relative to the insulating pull rod through hole and is kept at the position at the lower part of the insulating pull rod through hole.
Then utilize the moment spanner to rotate insulating pull rod 700 and carry out the check of moment, because manual operation's dynamics and power of exerting oneself custom problem, can produce decurrent pressure to insulating pull rod 700, the interior support wall 101 of backup pad 100 and the outer peripheral face supporting contact of insulating pull rod 700 this moment prevent it dislocation downwards, thereby can save subsequent reset operation, improve assembly efficiency, can also avoid insulating pull rod to damage the inside core spare part of solid seal utmost point post simultaneously, guarantee product quality, reduce the disability rate of product, and the economic benefits is improved.
