Single and double mounting point device for cross arm of steel pipe pole

Abstract

The invention discloses a single and double mounting point device for a cross arm of a steel pipe pole. The single and double mounting point device comprises the cross arm, a single-mounting point suspension plate I, a single-mounting point suspension plate II and double-mounting point suspension plates, wherein the single-mounting point suspension plate I and the single-mounting point suspension plate II are arranged at the front end of the cross arm; the double-mounting point suspension plates are respectively connected with the lower parts of the single-mounting point suspension plate I and the single-mounting point suspension plate II; the single-mounting point suspension plate I is parallel to the single-mounting point suspension plate II; and the single-mounting point suspension plate II is arranged behind the single-mounting point suspension plate I in the length direction of the cross arm. The single and double mounting point device has the beneficial effects that the single and double mounting point device is attractive in appearance, flexible and convenient; lead suspension plates are movably connected; the appearance is attractive; the problem that double suspension plates which are relatively large and relatively bulky in appearance are adopted when single-mounting point connection is required is avoided; standardization of the cross arm is facilitated; the lead suspension plates are movably connected; the form of the cross arm can be reduced; the standardization of the cross arm is facilitated; and installation, marking, construction and the like are facilitated.

Description

technical field [0001] The invention relates to a single and double hanging point device for a steel pipe pole cross arm, which belongs to power transmission equipment. Background technique [0002] With the rapid development of my country's electric power industry, in recent years, 220KV steel pipe poles for power lines have been used more and more widely. Well received by users. However, the cross arm, an important part of the 220KV steel pipe pole, is often not interchangeable due to differences in the use of power line fittings. Hanging or double-hanging both use double-hanging wire hanging boards, which are cumbersome in appearance and uneconomical and practical, and cause inconvenience to installation, identification, and construction. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art, and provides a single and double hanging point device for a steel pipe pole cross arm. [0004] The technical solutio...

However, the cross arm, an important part of the 220KV steel pipe pole, is often not interchangeable due to differences in the use of power line fittings. Hanging or double-hanging both use double-hanging form of wire hanging board, which is bulky in appearance and uneconomical and practical, causing inconvenience to installation, identification, construction, etc.
