Description
Technical Field
The utility model belongs to overhead line device mainly relates to cross arm for the pole, especially a cross arm for minor diameter toper pole.
Background
The general diagram of a railway 35kV overhead line is concentrated, and the installation mode of the ground wire cross arms aiming at JM4, JM6 and JM8 pole type ground wires is that the cross arms are connected with steel rings at the tops of poles with equal diameters of phi 300 through penetrating nails; in some special power engineering, however, tapered poles or poles with an outer diameter of less than 200mm are used.
There is no design related to the small diameter or tapered pole, and the 200mm ground wire cross arm which is commonly used cannot be directly connected and applied, so a new cross arm structure and fixed installation thereof need to be provided for the electric pole.
SUMMERY OF THE UTILITY MODEL
The utility model aims to fill prior art's blank, provide a rational in infrastructure, be less than 200mm and non-cylinder type pole to with the diameter have the cross arm for the minor diameter toper pole of extensive adaptability.
The utility model adopts the technical proposal that:
the utility model provides a cross arm for minor diameter toper pole, the cross arm includes the outer roof beam of two parallel interval installations, adopts the integrative welded fastening of many diagonal bars, its characterized in that between two outer roof beams: the both sides tip fretwork of cross arm sets up, installs a set of armful iron in corresponding fretwork position respectively, and every armful iron middle part levels both ends and forms the protruding portion and form type M type, and two armful iron opposite direction symmetries in the same group install, and the medial surface of four protruding portions all closely contacts with the outer fringe of toper pole.
And each holding iron comprises a back plate, the rear end face of the back plate is fixed with the outer beam at the same side, and the two sides of the front end face of the back plate are respectively provided with the protruding parts.
And two holding irons in the same group are fixed through a plurality of bolts, the bolts are all vertical to the outer beam, and the end parts of the two sides of the bolts are respectively arranged in the two outer beams in a penetrating way.
The utility model has the advantages that:
in the utility model, two groups of holding irons are adopted to fix the electric pole, each group comprises two M-shaped holding irons which are arranged oppositely, when the electric pole is installed, the protruding parts formed by the two holding irons are respectively and tightly pressed on the outer edge of the electric pole at the same side, so that the horizontal position of the cross arm is limited and fixed; in order to improve the stability of the cross arm, the contact area of the iron and the outer beam is effectively increased by adopting a structure that the back plate forms a protruding part; adopt many bolts to fix embracing the iron, restrict promptly with two relative position between the iron of organizing, the dress is worn in the pole to accessible one or many bolts again, makes the outer beam, embraces iron and pole an organic whole and fixes, promotes its fastness.

fig. 2 is a partially enlarged view of a portion a in fig. 1.
Detailed Description
The present invention is further illustrated by the following examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
The utility model provides a cross arm for minor diameter toper pole, the cross arm includes the outer roof beam 3 of two parallel interval installations, adopts the integrative welded fastening of many diagonal bars 4 between two outer roof beams, the utility model discloses an innovation lies in, the both sides tip fretwork of cross arm sets up 2, installs a set of armful iron in corresponding fretwork position respectively, and every armful iron middle part levels both ends and forms 6 types of formation type M types of protruding portion, and two armful iron opposite direction symmetries installation with organizing, the medial surface of four protruding portions all with the outer fringe in close contact with of toper pole.
In this embodiment, each holding iron comprises a back plate 5, the back end surface of the back plate is fixed to the outer beam on the same side, and the protruding portions are respectively formed on two sides of the front end surface of the back plate.
In this embodiment, two armful irons in the same group are preferably fixed through three bolts 9, and three bolts are all perpendicular with the outer beam, and the bolt that is located the middle part is worn out by the center of pole, and the bolt that is located both sides penetrates the outer beam by the backplate both ends of armful iron respectively in, and wherein one side tip passes through nut 8 locking fixed.
In this embodiment, a connecting rod 7 is respectively installed on both sides of the outer beam in a penetrating manner, and the cable connecting blocks 1 are respectively installed on both side end portions of the connecting rod in an integrated manner.
In the utility model, two groups of holding irons are adopted to fix the electric pole, each group comprises two M-shaped holding irons which are arranged oppositely, when the electric pole is installed, the protruding parts formed by the two holding irons are respectively and tightly pressed on the outer edge of the electric pole at the same side, so that the horizontal position of the cross arm is limited and fixed; in order to improve the stability of the cross arm, the contact area of the iron and the outer beam is effectively increased by adopting a structure that the back plate forms a protruding part; adopt many bolts to fix embracing the iron, restrict promptly with two relative position between the iron of organizing, the dress is worn in the pole to accessible one or many bolts again, makes the outer beam, embraces iron and pole an organic whole and fixes, promotes its fastness.
