Description

Rigid suspended doublet contact net of cranking arm
Technical field
The utility model relates to a kind of rigid suspended doublet contact net of cranking arm, and belongs to the equipment of power supply of urban orbit traffic.
Background technology
Before the utility model is made, in prior art, urban track traffic adopts rigid suspension catenary safety good in tunnel, copper contact wire can not break, though there is the patent No. to be the rigidity suspension bifilar contact net of 200420122395.5 and 201420034545.X, but their pendant is straight-arm, by subway tunnel limitation in height, pendant straight-arm length is partially short, elastic range is little, the easy plastic deformation of pendant straight-arm after installing with rule dolly, becomes large at every root bus duct two end dovetail furrow opening, can't clip copper contact wire, potential safety hazard is large.
Utility model content
The purpose of this utility model lengthens the total length of pendant under being the prerequisite that bus duct pendant bottom-to-top-height is constant, pendant elastic range is obviously strengthened, thus bus duct can clamp copper contact wire securely, provide a kind of rigid suspended doublet contact net of cranking arm of high reliability.
The main technical schemes that the utility model is dealt with problems is achieved in that the main two-wire bus duct 2 of cranking arm that adopts clamps 2 copper contact wires 1, the suspension that two-wire bus duct 2 of cranking arm is made up of crossbeam 3, insulator 4 and main hook 5 and pair hook 6 is placed in the below of subway tunnel roof, two-wire bus duct 2 of cranking arm has a band straight-arm pendant 8 of fixed jaw 9 and the pendant 7 of cranking arm of two sides, form two dovetail groove orifices 12, clamp 2 copper contact wires 1, form rigid suspended doublet contact net of cranking arm.
Compared with the prior art the utility model has the following advantages:
1, transmission current is large, temperature rise is low, without disconnection fault, wear away little, be suitable for DC1500V speed per hour be greater than 120KM/H electric locomotive use.
2, crank arm larger than the pendant of straight-arm more than three times of pendant 7 elastic range in two sides of bus duct, to copper contact wire firm grip.
3, the utility model compact conformation, the bottom-to-top-height of bus duct 2 and the bus duct of single line are all 110mm, and width is only 2/3rds of existing two-wire bus duct.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view that the utility model is arranged in subway tunnel.
Fig. 2 is the drawing in side sectional elevation that bus duct 2 in the utility model has filled copper contact wire 1.
Fig. 3 is the drawing in side sectional elevation before the bus duct 2 in the utility model is installed.
Fig. 4 is by main hook 5 and the drawing in side sectional elevation paying the suspension hook that hook 6 forms in the utility model.
Detailed description of the invention
With the embodiment in accompanying drawing, detailed description of the invention of the present utility model is described below:
In FIG, crossbeam 3 is placed under 2 reinforcing bars pre-buried in subway tunnel roof, on crossbeam 3, tapping hangs up insulator 4, the center in this hole is parameters from the width between centers of crossbeam 3, insulator 4 can be made to have different width between centerss from tunnel longitudinal centerline, thus make copper contact wire 1 relative tunnel longitudinal centerline have the stagger of gradual change, be increased to 280mm successively from 0, greatly can extend the life-span of the carbon brush of pantograph in electric locomotive.First at the below M16 bolt of insulator 4, main hook 5 is fixed on insulator 4 during construction, in the groove that muscle of being dashed forward the right, top of aluminium alloy extruded two-wire bus duct 2 of cranking arm again is placed in below main hook 5, then be brought together on main hook 5 with paying hook 6, bus duct 2 is just fixed on the aerial of tunnel, will pay hook 6 be fastened on main hook 5 with bolt.Adjacent bus duct 2 center coupling electrically and is mechanically coupling together, and the installation of bus duct 2 comes to an end.Finally opened by two of bus duct 2 dovetail groove orifices with special rule dolly, allow two copper contact wires 1 embed in the below dovetail groove orifice of bus duct 2, the main construction of installation completes.
Indicate the Each part of bus duct 2 in fig. 2, middle part is a straight-arm pendant 8, and its lower end is to two skew backs to respectively stretching out a fixed jaw 9.Two sides of bus duct 2 are two pendants 7 of cranking arm, its lower end respectively stretches out a fixed jaw 9 to the inside, and respectively stretch out a projection 11 laterally, the bottom of projection 11 has the ditch 10 that rises, projection 11 is for shelving the road wheel of rule dolly, the wheel that rises on rule dolly snaps in two outside spreading one fixed widthes of pendant of cranking arm after the ditch 10 that rises, being convenient to copper contact wire 1 embeds in bus duct, pendant 7 of cranking arm is oblique with 180 degree of bending secondaries, the total length of pendant 7 of making to crank arm increases greatly, thus make larger than straight-arm pendant 8 more than three times of the elastic range of two of bus duct 2 pendants 7 of cranking arm, the bottom-to-top-height of bus duct 2 gets 110mm, equal with the rigid suspended bus duct of common single line.Because the elastic range of two pendants 7 of cranking arm is large especially, therefore bus duct 2 produce that its lower end dovetail furrow opening when extruding can do very little, the elastic deformation of pendant 7 of cranking arm after copper contact wire is installed mediates value, and longitudinal direction two ends of bus duct 2 also allow rule installation carriage more spreading are to a certain degree by dovetail groove orifice when mounted, both be conducive to accelerating erection schedule, the distortion being also unlikely to make to crank arm pendant 7 exceeds elastomeric scope.The rigid suspended bus duct of common single line then often enters plastic deformation regime at this moment, and reliability is had a greatly reduced quality.
In figure 3, in a state of nature, opening is less for dovetail furrow opening 12.This same position is compared with Fig. 2, to embed after copper contact wire 1 dovetail furrow opening 12 many by spreading, illustrate that copper contact wire 1 is held very tight, each dovetail furrow opening 12 is that under the cranking arm by the fixed jaw 9 on the straight-arm pendant 8 of centre and adjacent outer, the fixed jaw 9 of outstanding body 7 is composed of.
Fig. 4 is the drawing in side sectional elevation of the suspension hook hanging bus duct 2, and the right is main hook 5, and hook 6 is paid on the left side.There is the hole of ф 17 in the middle of the top of main hook 5, be convenient to the bottom with M16 bolt, main hook being first fixed to insulator 4.The male-female engagement at the handing-over interface, left and right of main hook 5 and pair hook 6, the half weight of lower left bus duct 2 can be made after a pair hook 6 passes to main hook to pass to insulator 4 again and get on, the bolt in Fig. 4 plays and hooks together all-in-one-piece effect by main for left and right pair.
