Distribution engineering martingale structure
technical field:
The utility model relates to a kind of distribution engineering martingale structure.
background technology:
Can the regular strong point using electric pole and uses as corner in distribution engineering, electric pole in the past and support unreasonable, makes it easily be subject to extraneous wind effect and tilt or collapse, thus greatly affects the normal operation of electrical network.
summary of the invention:
The purpose of this utility model is to provide a kind of distribution engineering martingale structure, and this distribution engineering martingale structure is conducive to realizing good wind loading rating.
The utility model distribution engineering martingale structure, it is characterized in that: comprise a vertical rod and be located at vertical rod middle and upper part martingale load, vertical rod upper end is arranged with bracing wire anchor ear, between described martingale load outer end and bracing wire anchor ear, tractive has upper drag wire, described martingale load outer end is connected with a pull-down line in addition and is connected with the cable quadrant be embedded under earth's surface, described martingale load includes identical halved body, this halved body is by be arranged in parallel and two crosspieces misplaced are formed with the oblique section being connected two crosspieces, the projection with arc-shaped recess is provided with inside the first crosspiece.
Further, above-mentioned cable quadrant is a cement block.
Further, above-mentioned cement block and martingale are carried on a shoulder pole between outer end and are connected U-shaped draw ring, stay rod, UT wire clamp, bracing wire, wedge type clamp and prolongation ring successively.
Further, between above-mentioned martingale load outer end and bracing wire anchor ear, tractive has UT wire clamp, bracing wire, wedge type clamp and prolongation ring successively.
The utility model distribution engineering martingale structure has upper drag wire by arranging tractive between martingale load outer end and bracing wire anchor ear, described martingale load outer end is connected with a pull-down line in addition and is connected with the cable quadrant be embedded under earth's surface, described martingale load includes identical halved body, this halved body is by be arranged in parallel and two crosspieces misplaced are formed with the oblique section being connected two crosspieces, the projection with arc-shaped recess is provided with inside the first crosspiece, this arc-shaped recess holds vertical rod, the mating reaction of upper drag wire and pull-down line, allow the stressed of whole electric pole can be distributed to all directions equably, even if thus make electric pole be subject to different wind-force effects, also can be good at ensureing its stability.

detailed description of the invention:
The utility model distribution engineering martingale structure, comprise a vertical rod 1 and the martingale load 2 being located at vertical rod 1 middle and upper part, vertical rod 1 upper end is arranged with bracing wire anchor ear 3, described martingale carries on a shoulder pole tractive between 2 outer ends and bracing wire anchor ear 3 upper drag wire 4, described martingale load outer end is connected with a pull-down line 5 in addition and is connected with the cable quadrant 6 be embedded under earth's surface, described martingale load 2 includes identical halved body 7, this halved body is by be arrangeding in parallel and two crosspieces 701 misplaced, 705 are formed with the oblique section 702 being connected two crosspieces, the projection 704 with arc-shaped recess 703 is provided with inside the first crosspiece, this arc-shaped recess 703 holds vertical rod 1.The angle that two oblique sections 702 are formed is 16 degree.These 16 degree have best wind resistance effect.
In addition in order to make skidproof effect better, have horizontal groove 706 in arc-shaped recess 703, the whole length direction groove depth of this horizontal groove is all identical, and groove width is identical with separation.The shape of groove is V-type groove, is inlaid with V-type block rubber in V-type groove, and this V-type block rubber be located in V-type groove is more conducive to improving frictional force.
In order to make windproof effect good, vertical rod and ground are the angle of 93 degree.It is the opposite direction toward cable quadrant 6.
Further, in order to reasonable in design, above-mentioned cable quadrant is a cement block, and this cement block is embedded in 1.8-2.4 rice under earth's surface.
Further, in order to reasonable in design, above-mentioned cement block and martingale are carried on a shoulder pole and to be connected U-shaped draw ring 8, stay rod 9, UT wire clamp 10, bracing wire, wedge type clamp 11 between outer end successively and to extend ring 12.Certain cement block and martingale are carried on a shoulder pole between outer end and can directly be substituted with bracing wire.
Further, in order to reasonable in design, between above-mentioned martingale load outer end and bracing wire anchor ear, tractive has UT wire clamp 10, bracing wire, wedge type clamp 11 and extends ring 12 successively.Can directly substitute with bracing wire between certain martingale load outer end and bracing wire anchor ear.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
