Description
Technical field
The utility model belongs to electric device, and particularly a kind of power circuit scissors crossing construction is with crossing over frame.
Background technology
Along with developing rapidly of industrial and agricultural production, power circuit construction construction is like a raging fire.The power circuit of various electric pressures is ubiquity circuit scissors crossing problem in construction; Particularly the newly-built relatively line electricity of working line is forced down; Newly-built circuit must be striden handing over above the working line; Must have a power failure when friendship is striden, cause the contradiction of power customer and power circuit construction construction.In circuit scissors crossing when construction,, the general employing crossed over frame, and it is conventional method that present leap frame is set up what continue to use always; Mainly be steel pipe pole (using the screw snapping), China fir, bamboo pole (using the iron wire colligation) built, exist time-consuming, take a lot of work, require great effort, inefficiency; Dangerous; Expense is high, poor stability, because of being nearly electric operation, is prone to danger.
Summary of the invention
The purpose of the utility model is to provide a kind of electric power live across frame of crossing over 110KV and following alive circuit and railway, highway, communication line that is applicable to.
The utility model is achieved in that
Electric power live across frame mainly comprises pedestal and support body, it is characterized in that: said pedestal is formed by the vertical duct bar and the transverse pipe bar overlap joint of insulation, and the transverse pipe bar is overlapped to form quadrangle, and the vertical duct bar is positioned at the lap-joint of two transverse pipe bars; Diagonal along the pedestal side is overlapped with stable pipe bar; Said support body is made up of the column of insulation of overlap joint on pedestal, is overlapped with stay tube pole between the adjacent upright posts and between the square plane that surrounds of four root posts.
After the utility model adopts said structure, adopt insulated pipes used moistureproof, high mechanical properties, through peg graft, the snapping mode is overlapped to form the power ride-through frame, and is easy for installation, connect reliable, applying flexible.Can realize multiple application combination according to the site operation needs, split freely that the support body height is easy to adjust.And can use no spillage of material repeatedly.Have mechanical strength height, in light weight, the effect being convenient to transport.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model, and Fig. 2 is the user mode reference diagram of the utility model.
In the accompanying drawing, 1 is that vertical duct bar, 2 is the reinforced pipe bar for cross pipe bar, 9 for end face pipe bar, 8 for cable wind rope, 7 for stay tube pole, 6 for column, 5 for stable pipe bar, 4 for transverse pipe bar, 3.
Embodiment
Embodiment to the utility model elaborates below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is an electric power live across frame, mainly comprises pedestal, support body.Pedestal is formed with transverse pipe bar 2 overlap joints by the vertical duct bar 1 of insulation, and transverse pipe bar 2 is overlapped to form quadrangle, and vertical duct bar 1 is positioned at the lap-joint of two transverse pipe bars 2; Diagonal along the pedestal side is overlapped with stable pipe bar 3, forms stable tripod structure, improves the stabilization of support body, and guarantees that pedestal is perpendicular to the ground.Vertical duct bar 1 is unified with transverse pipe bar 2 models, is convenient to generally, improves practicality.Adopt between the transverse pipe bar 2 that overlaps and between transverse pipe bar 2 and the vertical duct bar 1 and peg graft and two kinds of forms of snapping; At the pipe boom end clasp is set during snapping, will manages bar through snap-hook structure and snap together; At the pipe boom end plug, slot are set respectively during grafting, the plug through cooperatively interacting, inserting slot construction are with together pipe lever connected.Said support body is made up of four root posts 4 of insulation of overlap joint on pedestal, is overlapped with stay tube pole 5 between the adjacent upright posts 4 and between the square plane that surrounds of four root posts 4.Stay tube pole 5 adopts frame structure or cross structure, also can adopt chi structure, and 4 on column 4 and column are combined together each other, guarantees the stable of whole leap frame.Also overlap through grafting and two kinds of forms of snapping between column 4 and the pedestal and between stay tube pole 5 and the column 4, bridging arrangement is identical with the overlapping mode of pedestal.Said pedestal and support body material all adopt high strength insulated tube pole stock, with the raising support strength, and guarantee insulation property.
When increase crossing over the height of frame, as shown in Figure 2, can on support body, overlap other support body again, analogize in proper order and reach the requirement height.When crossing over the frame height and surpass 20 meters, should be on support body column 4 middle parts and support body tractive cable wind rope 6, cable wind rope 6 fixes on the ground.End face at the superiors' support body is overlapped with end face pipe bar 7 and cross pipe bar 8 or inclined tube bar, is used to bind; Add the slip wheel shaft on the end face pipe bar 7, overhead ground wire or the lead being convenient to set up pass through, and cross over and lay the nylon wire protection between the frame.
During use, general circuit adopts four to cross over frame (two of every sides); When construction line and crossed line angle are big, adopts six leap framves (three of every sides); Adopt two to cross over framves when highway, the leap of railway both sides; It is single getting final product that connection is crossed over frame.When employing is crossed over frame more than two, overlap joint reinforced pipe bar 9 between the adjacent leap frame, bracing piece can adopt inclined or staggered form, also can adopt the run-in index structure.
Cross over the main designing technique parameter of frame:
Cross over distance: 4～45 meters.
Crossing over maximum binds highly: 25 meters.
Maximum axial load (rated load) 20KN that allows.
The single static pressure 2.3kN that bears of insulated tube pole stock does not have distortion, and insulating properties is not less than 175KV/m,
Industrial frequency withstand voltage 1min requirement.
Design safety factor (DSF): 1.5.
