In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The single-hanging-point cross arm changed double-hanging-point mounting fixture shown in fig. 2, 3 and 4 comprises a base 1, a cover plate 2 and an extension rod 3.
The base 1 is in an angle steel shape and comprises a vertical part and a horizontal part; the vertical part or the horizontal part is provided with a cross arm connecting hole 4; in the present embodiment, the cross arm connecting hole 4 is provided in the vertical portion, and the cross arm connecting hole 4 of the base 1 is connected to the cross arm hanging hole 10 of the single hanging point cross arm 9 by a bolt, so that the base 1 is mounted on the single hanging point cross arm 9.
The cover plate 2 is obliquely arranged at the upper end of the base 1, one side of the cover plate 2 is positioned at the edge of the vertical part, and the other side of the cover plate 2 is positioned at the edge of the horizontal part; the cover plate 2 and the base 1 form a hollow triangular prism shape.
More specifically, the upper ends of the base 1 and the cover plate 2 are respectively provided with a horizontal upper connecting lug plate 6; the lower ends of the base 1 and the cover plate 2 are respectively and correspondingly provided with a vertical lower connecting lug plate 7; and the upper connecting lug plate 6 and the lower connecting lug plate 7 are respectively provided with a cover plate connecting hole 8, and the base 1 is connected with the cover plate 2 through the matching of bolts and the cover plate connecting holes 8. The cover plate connecting holes 8 are four in the embodiment, namely two are symmetrically arranged on the upper connecting lug plate 6, and two are symmetrically arranged on the lower connecting lug plate 7, so that the base 1 and the cover plate 2 are well connected into a whole.
The extension rod 3 is fixed on the base 1, at least two fixture hanging holes 5 are formed in the extension rod 3, and the distance between the two fixture hanging holes 5 is 40-60 cm. Extension rod 3 welded fastening is in the vertical portion or the horizontal part of base 1, and extension rod 3's both ends are equipped with at least one fixture hanging hole 5 respectively. The extension pole 3 in this embodiment is preferably welded and fixed to the vertical portion of the base 1, so that the extension pole 3 is more resistant to bending. When the vertical part is provided with the cross arm connecting hole 4, the extension rod 3 can bypass the cross arm connecting hole 4, a through hole corresponding to the cross arm connecting hole 4 can be arranged on the extension rod 3, and of course, the extension rod 3 can be cut off at the cross arm connecting hole to form two parts which are respectively welded and fixed with the vertical part.
