Description
Technical field
The utility model relates to a kind of stringing of the electric power transmission line for rural power grids, urban network restructuring power steel pipe rod.Especially a kind of power steel pipe rod that can significantly reduce lifts danger, reduces the pull rod type power steel pipe rod of difficulty of construction.
Background technology
At present, known electric pressure 10KV and more than 10KV for rural power grids, the electric power transmission line stringing power steel pipe rod of urban network restructuring, that steel pipe pole by many single-units lifts section by section connection and forms, the cross-arm of this power steel pipe rod is fixed in the body of rod position of steel pipe pole, should be noted the locality of body of rod cross-arm when the lifting steel pipe pole, it is the mounting means of a kind of fixed-direction position, having increased the danger of power steel pipe rod lifting and the utility model patent name of difficulty of construction application is called: " pull rod type power steel pipe rod ", the patent No. is: the cross-arm of the pull rod type power steel pipe rod of ZL2012 2,008 1148.9 fixedly line is fixedly mounted on the steel pipe pole body of rod, the locality that body of rod cross-arm still occurs during installation is difficult to the problem of regulating.。
Summary of the invention
Should be noted the direction of body of rod cross-arm in order to overcome existing power steel pipe rod when lifting steel pipe pole, the danger of the steel pipe pole that increases electric power lifting and the defect of difficulty of construction, the utility model provides a kind of active cross-arm type power steel pipe rod, can significantly reduce the lifting construction difficulty of power steel pipe rod, reduce the construction danger that lifting is installed.
Technical solution of the present utility model: tentatively complete on the lifting power steel pipe rod body of rod of standing, cross-arm, the cross-arm groove is anchor ear fixedly, cross-arm fixedly binds round in groove, cross-arm fixed card slot steel plate, the cross-arm Fixing clamp-seat, set bolt, fixing threaded hole, the cross-arm fixedly interior hoop of groove anticreep draw-in groove is sequentially installed connection, it is characterized in that: by the fixing anchor ear of cross-arm groove, cross-arm fixedly binds round in groove, set bolt, fixing threaded hole, cross-arm fixedly binds round the anticreep draw-in groove in groove, cross-arm is sequentially installed the active type cross-arm of the minor diameter that connects into steel pipe pole installation component, by cross-arm fixed card slot steel plate, the cross-arm Fixing clamp-seat, cross-arm, set bolt, fixing threaded hole is sequentially installed the active type cross-arm of the major diameter that connects into steel pipe pole installation component.Wherein, in the active type cross-arm of minor diameter installation component, cross-arm groove fixedly anchor ear is that two Ω types can the symmetrical steel ring anchor ear of installing, and cross-arm groove fixedly anchor ear presets fixing threaded hole, and presetting the cross-arm mounting terminal, cross-arm groove fixedly anchor ear steel ring inboard presets uniform steel groove.Cross-arm fixedly in groove hoop be that two C types can the symmetrical steel ring anchor ear of installing, the cross-arm fixedly interior hoop iron circle outer upper end of groove also presets the steel groove uniformly, lower end is preset cross-arm and fixedly in groove, is bound round the anticreep draw-in groove, cross-arm fixedly also presets the fixing threaded hole of oval grooved on the interior hoop of groove uniformly, the position of fixedly binding round in groove with fine adjustment cross-arm easily, increase the direction adjustability of cross-arm, lifting can be first during steel pipe pole by the cross-arm groove, fixedly anchor ear and cross-arm fixedly bind round in groove and are contained in advance in advance on the steel pipe pole body of rod, lift again cross-arm after the rigging out fine setting is fixing.The cross-arm groove fixedly the inboard preset steel groove of anchor ear steel ring can with cross-arm fixedly in groove the even preset tight interlock of steel groove of hoop iron circle outer upper end fix, with the fixing anchor ear steel ring left-right rotation of the cross-arm groove after preventing from installing, cross-arm fixedly in groove the preset cross-arm in hoop iron circle lower end fixedly in groove hoop anticreep draw-in groove can prevent the fixedly anchor ear steel ring downslide of cross-arm groove, these settings can effectively increase the cross-arm stability after the installation.Wherein, in the active type cross-arm of major diameter installation component, cross-arm fixed card slot steel plate is
type draw-in groove steel plate, its upper and lower side presets fixing threaded hole uniformly, on the steel pipe pole body of rod two cross-arm fixed card slot steel plates up and down symmetrical the installation form the cross-arm fixed card slot, cross-arm fixed card slot steel plate is arranged on the fixing threaded hole that presets oval grooved on the end draw-in groove steel plate limit on the body of rod, the other end presets circular fixing threaded hole, such setting fine adjustment cross-arm fixed card slot steel plate easily, in the direction position of the body of rod, increases the direction adjustability of cross-arm.The cross-arm Fixing clamp-seat is the T-shaped end steel cross-arm Fixing clamp-seat with the cross-arm mounting terminal, presets fixing threaded hole on it.Be combined into the cross-arm fixed card slot by two cross-arm fixed card slot steel plates symmetrical installation on the steel pipe pole body of rod, again the cross-arm Fixing clamp-seat is crossed and snap in by two cross-arm fixed card slot steel plates symmetrical installation in the cross-arm fixed card slot be combined on the steel pipe pole body of rod, again cross-arm, set bolt, fixing threaded hole are sequentially installed to connect and be combined into the active type cross-arm of major diameter installation component, can first cross-arm fixed card slot steel plate and cross-arm Fixing clamp-seat be contained on the steel pipe pole body of rod in advance in advance during the lifting steel pipe pole, after the rigging out fine setting is fixing, lift again cross-arm.The active cross-arm type power steel pipe rod body of rod is installed the cross-arm position should uniformly presetly have the large outer young broadening formation fixing threaded hole of internal orifice, uses the expansion set bolt so that fixedly cross-arm installation component (the outer ring expansion steel ring of expansion set bolt should adopt high-intensity elasticity steel to reach safe structural strength) to be installed herein.Complete the installation process that above operation can complete active cross-arm type power steel pipe rod cross-arm installation component.The cross-arm direction of the attention power steel pipe rod body of rod that can be deliberately when the lifting of active cross-arm type power steel pipe rod is installed, reduce the danger of difficulty of construction and lifting construction.
The beneficial effects of the utility model are, but the lifting power steel pipe rod of any direction when the power steel pipe rod lifting is installed, and the directed cross-arm that is completed cross-arm by active type cross biling assembly is installed.Can reduce significantly the lifting construction difficulty of power steel pipe rod, reduce the construction danger that lifting is installed.
