The utility model discloses can effectual online reduction with eliminate the torsional stress in the stranding after the transposition, need not not use when construction of pay -off and prevent turning round the whip, can improve the speed of construction, can strengthen the security of construction again, enable not have the OPGW one shot forming of torsion, avoided secondary operation, improved production efficiency.
Description
【Technical field】
This utility model belongs to fiber optic cable manufacture technical field, the online back twist of more particularly to a kind of OPGW
Device.
【Background technology】
OPGW (abbreviation OPGW) has ground wire and communications optical cable dual-use function concurrently, has good technical
Energy and economic benefit, have obtained universal application in global power system at present.OPGW has double-deck strand and two kinds of monolayer strand
Model, double-deck strand is to rotate stranded optical cable round about by two cages, will not produce torsion；And monolayer twist be by
One cage is stranded to a direction rotation, and the direction of this rotation is easy to make optical cable produce reversing to the direction
Individual stress, its wire rod easily occurs from the situation twisting, and affects twisted wire quality.In the construction line-putting, the OPGW that monolayer twists is installed simultaneously
When it is necessary to prevent the distortion of optical cable using anti-whip of turning round, if anti-torsion whip improper use easily causes ticking, extrude equivalent damage optical cable
Phenomenon, or even cause the disconnected fine, cable breakout of optical fiber, have a strong impact on construction safety and speed of application.
Therefore, it is necessary to provide a kind of online back-twist device of new OPGW to solve the above problems.
【Utility model content】
Main purpose of the present utility model is to provide a kind of OPGW online back-twist device, and it can be
Line reduce and eliminate stranded after stranding in distorting stress.
This utility model is achieved through the following technical solutions above-mentioned purpose：A kind of OPGW online back twist dress
Put, it includes having the first support plate of vertical plane, has the second support plate of horizontal plane, is fixed on described first support plate
Longitudinal back twist assembly and be fixed on the horizontal back twist assembly on described second support plate.
Further, described longitudinal back twist assembly include along the stranding direction of motion setting the first roller and the second roller,
It is arranged on the first back twist roller of top position between described first roller and described second roller and adjustable be fixedly installed on
The first adjusting rod on described first support plate.
Further, described first back twist roller is fixed on described first adjusting rod.
Further, described horizontal back twist assembly includes described 3rd roller along the setting of the stranding direction of motion and the 4th rolling
Wheel, it is arranged between described 3rd roller and described 4th roller the second back twist roller of front or behind position and adjustable solid
It is scheduled on the second adjusting rod on described second support plate.
Further, described second back twist roller is fixed on described second adjusting rod.
Compared with prior art, a kind of beneficial effect of the online back-twist device of OPGW of this utility model exists
In：
1) can effectively reduce online and eliminate stranded after stranding in distorting stress；
2) without the OPGW of back twist, usual twist is 72-90 degree/rice, must use anti-torsion whip in the construction line-putting,
And the twist through the OPGW of this utility model device is reduced to 18-36 degree/rice, anti-torsion need not be used in the construction line-putting
Whip, can improve the speed of construction, can enhance the safety of construction again；
3) the OPGW one-shot forming of torsionless can be made, it is to avoid secondary operations, improve production efficiency.
【Brief description】
Fig. 1 is the structural representation of this utility model embodiment；
In figure numeral represents：
The online back-twist device of 100 OPGWs；101 optical cables；1 first support plate；2 second support plates；3 longitudinal back twists
Assembly, 31 first rollers, 32 second rollers, 33 first back twist rollers, 34 first adjusting rods；4 horizontal back twist assemblies, 41 the 3rd rollings
Wheel, 42 the 4th rollers, 43 second back twist rollers, 44 second adjusting rods.
【Specific embodiment】
Embodiment：
Refer to Fig. 1, the present embodiment is the online back-twist device of OPGW 100, and it includes having vertically puts down
First support plate 1 in face, second support plate 2 with horizontal plane, the longitudinal back twist assembly 3 being fixed on the first support plate 1 and solid
It is scheduled on the horizontal back twist assembly 4 on the second support plate 2.
Longitudinal back twist assembly 3 includes the first roller 31 and the second roller 32 along the setting of stranding 101 direction of motion, is arranged on
First back twist roller 33 of top position and be fixed on the first support plate 1 first between first roller 31 and the second roller 32
Adjusting rod 34.First back twist roller 33 is fixed on the first adjusting rod 34.
Laterally back twist assembly 4 includes the 3rd roller 41 along the setting of stranding 101 direction of motion and the 4th roller 42, is arranged on
Second back twist roller 43 of front or behind position and being fixed on the second support plate 2 between 3rd roller 41 and the 4th roller 42
The second adjusting rod 44.Second back twist roller 43 is fixed on the second adjusting rod 44.
First roller 31, the second roller 32, the first back twist roller 33, the 3rd roller 41, the 4th roller 42 and second move back
Turn round roller 43 outer peripheral profiled surface and be provided with the groove (in figure does not indicate) housing stranding 101.
When stranding 101 sequentially passes through the first roller 31, the second roller 32, the 3rd roller 41 and four rollers 42, pass through
First back twist roller 33 and the second back twist roller 43 are to the vertically and horizontally applying pressure of stranding 101 so that passing through
Stranding 101 through extruding after discharge stress, thus reduce or eliminate stranding 101 in distorting stress.
The having the beneficial effects that of the online back-twist device of the present embodiment OPGW 100：
1) can reduce online and eliminate stranded after stranding in distorting stress；
2) without the OPGW of back twist, usual twist is 72-90 degree/rice, must use anti-torsion whip in the construction line-putting,
