Embodiment Construction

[0030] Such as figure 1 As shown in the schematic diagram of the assembly joint of the aluminum pipe joint, the outer joint 1 is inserted into the inner joint 2, and the two ends of the two aluminum tubes 3 are inserted into the outer joint 1 of the aluminum tube, and are sleeved outside the inner joint 2, and the two aluminum tubes 3 withstand the At the boss 4 in the middle 2 of the inner joint, the outer joint 1 is composed of two identical semi-elliptical aluminum tubes, which are connected by bolts 6 from the outside to the inside, so that a circular cavity is formed inside the outer joint 1. Figure 9 shown.

[0031] Such as figure 2 and 3 As shown, a boss 4 is set in the middle of the inner joint 2, the outer diameter of the inner joint is 2 mm smaller than the inner diameter of the aluminum tube, the tolerance control is within ±0.2 mm, and the wall thickness of the inner joint is 9-10 mm.

[0032] Such as Figure 4 , 5 , 6, 7 and 8, the outer joint 1 is displaye...

Abstract

The invention relates to an aluminum pipe joint of an anti-slipping aluminum pipe jumper wire. The aluminum pipe joint comprises an outer joint and an inner joint. The inner joint is provided with a pipe fitting with a circular convex plate, the inner wall of the outer joint is arc-shaped, and the outer joint is provided with corresponding connecting holes. A circular clamping groove is arranged inside the outer joint, the structure of the aluminum joint is enabled to be stable, and a mechanical performance and an electrical performance are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of overhead power transmission line fittings, in particular to an aluminum pipe joint for an anti-slip aluminum pipe jumper. Background technique [0002] In UHV line engineering, in addition to reducing the size of the tower head to save steel and reduce costs, 500kV lines usually use rigid jumpers to meet engineering needs. Due to the reasonable distance between the rigid jumper and the grounding of the tower, the sag of the jumper is reduced. At the same time, due to the rigidity of the jumper, its swing range can be greatly reduced under the action of wind, so the length of the cross arm can be shortened. The existing hard jumper structures mainly include cage jumper and aluminum tube jumper. The aluminum tube jumper has good economy and has been widely used in UHV projects. The aluminum tube jumper is mainly composed of several parts: aluminum tube, aluminum tube joint, aluminum tube spacer, suspensio...
