Description
Technical field
The utility model belongs to KV Electric Transmissions technical field of construction, relates in particular to a kind of support of the V-type end for high ferro crossing frame.
Background technology
Because the diameter of leads of ultra-high voltage power transmission lines is large, totally-enclosed, the full-overpass formula operation of Heavy Weight and high-speed railway, traditional leap high ferro stringing technology can not meet newly-built circuit across high-speed rail construction requirement, need to develop a kind of novel crossing frame form of one that can adapt to extra-high voltage grid construction, solve a leap difficult problem for UHV transmission line Poling Construction.
Traditional leap carrier cable adopts Di Nima rope more, and application life is limited, and protection difficulty is large; large to the impact force of rope after wire is de-, between wire and rope, there is relative sliding, easy damaged wire; affect the construction quality of spreading conducting wire, be unfavorable for the safe operation of electrical network.
Utility model content
The utility model is in order to solve weak point of the prior art, and a kind of be easy to unfold rope and wire effective protection rope and wire is injury-free, construction safety is reliably for the V-type end support of high ferro crossing frame are provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: for the V-type end support of high ferro crossing frame, comprise left frame and correct frame, the lower end of left frame is fixedly connected with the lower end of correct frame, angle between left frame and correct frame is greater than 0 ° and be less than 180 °, the top, junction of left frame and correct frame is rotatably connected to roll shaft, and the left side, upper end of left frame is provided with left otic placode, and the right side, upper end of correct frame is provided with auris dextra plate.
Described roll shaft is that nylon material is made, left frame is with correct frame the steel truss structure that structure is identical, this steel truss structure comprises two back timbers on top and a foundation beam of bottom, between two back timbers and a foundation beam, be fixedly connected with raker beam by crossbeam, the length of back timber is greater than the length of a foundation beam.
Described two back timbers and the junction of foundation beam between left frame and correct frame all bend as horizontal structure, between the back timber of left frame and correct frame back timber and all correspondingly between the bottom girder of left frame and the bottom girder of correct frame connect as one by flange.
Angle between described left frame and correct frame is 90 °.
Adopt technique scheme, left otic placode and auris dextra plate flexibly connect by connecting rope with the crossing frame of both sides respectively, are convenient to like this install.Roll shaft arrange become sliding friction be rolling friction, like this can guardwire and rope.Roll shaft adopts nylon material to make, and so further guardwire and rope, has also reduced weight and cost.It is leg-of-mutton steel truss structure that left frame and correct frame adopt cross section, so not only improves stability, and weight reduction cost-saving.Two back timbers and the junction of foundation beam between left frame and correct frame all bend as horizontal structure, are convenient to like this adopt flange connection to removably connect, and play easy-to-mount effect.
The utility model design, simple in structure, safe and reliable; can effectively extend the time of contact of come off wire and carrier cable; reduce the impact force of large-section lead to carrier cable; wire can move while being slipped to left frame and correct frame centre on roll shaft; the rolling of roll shaft drives wire walking; replace the sliding friction between conventional wires and carrier cable, wire has been played a very good protection.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is plane structure schematic diagram of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, V-type end for high ferro crossing frame support of the present utility model, comprise left frame 4 and correct frame 5, the lower end of left frame 4 is fixedly connected with the lower end of correct frame 5, included angle A between left frame 4 and correct frame 5 is greater than 0 ° and be less than 180 °, preferably 90 ° of A, and the top, junction of left frame 4 and correct frame 5 is rotatably connected to roll shaft 1, the left side, upper end of left frame 4 is provided with left otic placode 2, and the right side, upper end of correct frame 5 is provided with auris dextra plate 3.
Roll shaft 1 is made for nylon material, left frame 4 is with correct frame 5 steel truss structure that structure is identical, this steel truss structure comprises two back timbers 6 on top and a foundation beam 7 of bottom, between two back timbers 6 and a foundation beam 7, be fixedly connected with raker beam 10 by crossbeam 9, the length of back timber 6 is greater than the length of a foundation beam 7.
Two back timbers 6 and the junction of a foundation beam 7 between left frame 4 and correct frame 5 all bend as horizontal structure, all correspondingly between the back timber 6 of left frame 4 and correct frame 5 back timbers 6 and between the bottom girder 7 of left frame 4 and the bottom girder 7 of correct frame 5 be connected (flange bolt 8) by flange and be integrated.
The utility model, in the time that work is used, flexibly connects with the crossing frame 11 of both sides left otic placode 2 and auris dextra plate 3 respectively by connecting rope, be convenient to like this install.Roll shaft 1 arrange become sliding friction be rolling friction, like this can guardwire and rope.Roll shaft 1 adopts nylon material to make, and so further guardwire and rope, has also reduced weight and cost.It is leg-of-mutton steel truss structure that left frame 4 and correct frame 5 adopt cross section, so not only improves stability, and weight reduction cost-saving.Two back timbers 6 and the junction of a foundation beam 7 between left frame 4 and correct frame 5 all bend as horizontal structure, are convenient to like this adopt flange connection to removably connect, and play easy-to-mount effect.
