Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
Embodiment one: shown in accompanying drawing 1.Be applied to the two open loop steel pipe poles in power transmission and transformation line, it comprises the supervisor 1 that vertically arranges and to arrange in the horizontal direction and one end is connected to several cross-arms 2 on supervisor 1.
Supervisor 1 for cross section be the conical pipe of regular polygon, the sectional area of its underpart is greater than the sectional area on its top, namely supervisor 1 sectional area reduce gradually from the bottom to top.The segmentation 11 that supervisor 1 is divided into some ends to dock successively, the syndeton between two segmentations 11 connected comprises a pair flange 3 of the end being arranged at two segmentations 11 connected, the fastening bolt assembly (not shown) of several axis vertical ground adpting flanges 3.The bottom of the segmentation 11 of foot can mounting seat, supervisor 1 can be fixedly installed on its installed surface.
Cross-arm 2 is arranged on the differing heights position of supervisor 1, in the present embodiment, supervisor 1 is provided with altogether four height and positions installed for cross-arm 2.Each height and position comprises three cross-arms 2, in these three cross-arms 2, two cross-arm 2 axis collinear are also distributed in the both sides of supervisor 1, and can be called horizontal cross-arm, the axes normal of another cross-arm 2, in other two cross-arms 2, can be called longitudinal cross-arm.In three cross-arm 2 circumferences being arranged in supervisor 1 in T shape, wherein, two cross-arms 2 of axis collinear form the horizontal of T, and another cross-arm 2 forms one of T and erects, and the arrangement orientation of three cross-arms 2 on each height and position is identical.The cross-arm 2 being positioned at the height and position place of the top is the ground wire cross-arm of erection ground wire, and the cross-arm 2 at all the other height and position places is the wire cross-arm of erection wire.Therefore, in each horizontal cross-arm, the horizontal cross-arm being positioned at the top is referred to as horizontal ground wire cross-arm 21, and all the other horizontal cross-arms are referred to as horizontal wire cross-arm 22; In each longitudinal cross-arm, the longitudinal cross-arm being positioned at the top is referred to as longitudinal ground wire cross-arm 23, and all the other longitudinal cross-arms are referred to as longitudinal wire cross-arm 24.
Cross-arm 2 is also the conical pipe that cross section is regular polygon, and the sectional area of one end be connected with supervisor 1 of cross-arm 2 is greater than the sectional area of its other end.One end that definition cross-arm 2 is connected with supervisor 1 is its inner end, and the end be not connected with supervisor 1 is its outer end, then the sectional area of cross-arm 2 is reduced gradually by the outside end of its inner end.In three cross-arms 2 on each height and position, two cross-arms 2 of axis collinear, i.e. horizontal cross-arm, the both sides in the middle part of it and the both sides of outer end thereof are provided with the wire link plate 7 opening hole; With another cross-arm 2 that two cross-arms 2 of axis collinear are perpendicular, i.e. longitudinal cross-arm, it is only provided with the wire link plate 7 opening hole in the both sides of outer end.
Syndeton between supervisor 1 and each cross-arm 2 comprises the plate assembly be arranged on cross-arm 2, is arranged at the erection bolt assembly 6 of upper gusset plate assembly, even patch panel assemblies and the gusset plate assembly of supervisor 1.
Gusset plate assembly is made up of the gusset plate 51 be fixedly connected with supervisor 1, gusset plate 51 is fixedly connected with horizontal-extending and several ring stiffeners 52 distributed around supervisor 1.In the present embodiment, each gusset plate assembly comprises two gusset plates vertically be arranged in parallel mutually 51 be fixedly connected on supervisor 1, and the spatial placement between two adjacent gusset plate assemblies has ring stiffener 52.
Plate assembly at least comprises the plate 41 paralleling setting with gusset plate 51.In the present embodiment, each plate assembly cross-wise direction comprised along cross-arm 2 is extended and the junction plate 42 being fixedly installed on the inner end of cross-arm 2, two plates vertically be arranged in parallel mutually 41 being fixedly connected on cross-arm 2 by junction plate 42.Two plates 41 insert in the space between two gusset plates 51, and plate 41 reclines correspondingly mutually with gusset plate 51.Radial direction junction plate 42 is provided with along the cross section of cross-arm 2 extends and several plate stiffeners 43 distributed around cross-arm 2.
The gusset plate 51 reclined mutually correspondingly and plate 41 are fixedly connected by several erection bolt assemblies 6, each erection bolt assembly 6 comprises screw rod and two nuts matched with screw rod of the screw run through on gusset plate 51 and plate 41, two nuts lay respectively at the both sides of the assembly that a plate 41 and gusset plate 51 are formed, thus by the relative position locking of plate 41 and gusset plate 51.
The steel material of this pair of open loop steel pipe pole both can select the common iron of Q235, Q345, also the high strength steel of Q390, Q420 or Q460 can be adopted, the blanking of each rod member, punching, zinc-plated operation is carried out according to construction drawing, part-connection location (link position as the link position of gusset plate 51 and supervisor 1, plate 41 and junction plate 42) adopts and is welded to connect, and each component completion of processing is transported to that scene carries out installing, stringing.Bolt assembly can adopt 6.8 grades of plain bolts or 8.8 grades of high-strength bolts, and high-strength bolt tightens by certain pretightning force.
This Novel double open ring steel pipe pole simple structure, replaces the large corner pole of two bases with a base open loop shaft tower, decreases the quantity of material on steel tower and basis, effectively reduces shaft tower floor space simultaneously, reduce line corridor width.And the monnolithic case of this Novel double open ring steel pipe pole is attractive in appearance, can be used in the middle of 110kV, 220kV double back power transmission and transformation line engineering.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
