On a platform sling, the platform sling is fixed between one end of a pair of of connecting plate, is folded between the other end of the pair of connecting plate
A piece coaster pin shaft, the coaster pin shaft are equipped with bushing, and the bushing passes through the pair of vertical plate and stands with the pair of
Plate is rotatably coupled.
The digital electronic frequency conversion drive variable diameter optical cable dedicated pulley, in which: between the pair of connecting plate
It is also equipped with a guide shaft, deflector roll is cased on the guide shaft, the deflector roll is located at the peripheral side of the elliptic pulley group.
The digital electronic frequency conversion drive variable diameter optical cable dedicated pulley, in which: be equipped in the coaster pin shaft
The through type lubricating cup of lubricating oil is provided to the bushing.
The digital electronic frequency conversion drive variable diameter optical cable dedicated pulley, in which: deviate in the two sides of hanging ring certain
Also be respectively provided with a gag lever post group at angle, the gag lever post group is made of a upper bar with two side block bars, it is described on
Bar is connected between two side block bars, and the side block bar is respectively fixed on the outside of a vertical plate, thus described
The peripheral side of elliptic pulley group forms the limit space of frame-type.
The digital electronic frequency conversion drive variable diameter optical cable dedicated pulley, in which: the vertical plate is in C font.
Since the present invention forms elliptic pulley group, using the larger radius of curvature of ellipse to adapt to larger radius of curvature
Hawser keep hawser sliding in ellipse using the rotation of idler wheel simultaneously because elliptic pulley group is made of multiple idler wheels
It is free to slide in wheel group, it ensure that the working performance of pulley blocks, meanwhile, radius of curvature of the present invention is greatly and the diameter of pulley blocks is small,
While the winding demand for meeting hawser, coaster volume can be reduced.

Specific embodiment
As shown in Figure 1 and Figure 2, the digital electronic frequency conversion drive variable diameter optical cable dedicated pulley of one kind provided by the invention, packet
It includes:
A pair of of vertical plate 6 is in arranged for interval, is respectively in C font；
Multiple idler wheels 9, the multiple idler wheel 9 respectively by a roller shaft 7 be installed in rotation on the pair of vertical plate 6 it
Between, and the multiple idler wheel 9 arranges ovalisation, to form elliptic pulley group；It is set between the idler wheel 9 and roller shaft 7
There is bearing 20, to improve rotation flexibility；
Hanging ring 1 is connect with the pair of vertical plate 6；Wherein, the hanging ring 1 is fixed on a platform sling 101, the platform sling
101 are fixed between one end of a pair of of connecting plate 2,3, are also folded with a cunning between the other end of the pair of connecting plate 2,3
Vehicle pin shaft 12, the coaster pin shaft 12 be equipped with bushing 11, the bushing 11 pass through the pair of vertical plate 6 and with it is the pair of
Vertical plate 6 is rotatably coupled；It is also equipped with a guide shaft 5 between the pair of connecting plate 2,3, is cased with and leads on the guide shaft 5
Roller 4, the deflector roll 4 are located at the peripheral side of the elliptic pulley group, and optical cable is limited to the deflector roll 4 and the idler wheel
Between 9, prevent optical cable from beating.
Wherein, through type lubricating cup 23 is equipped in the coaster pin shaft 12, for providing lubricating oil to the bushing 11.
In addition, as shown in Figure 1, Figure 3, deviateing in the two sides of hanging ring 1 and being also respectively provided with a limit at certain angle (such as 43 degree)
Position bar group, the gag lever post group are made of a upper bar 29 with two side block bars 28, and the upper bar 29 is connected to described
Between one end of two side block bars 28, the other end of the side block bar 28 respectively passes through bolt 30 at two and is fixed on the vertical plate
6 outside, to form the limit space of frame-type in the peripheral side of the elliptic pulley group；Optical cable passes around sliding in ellipse
When the peripheral side of wheel group, it will receive the limit of two gag lever post groups Yu the deflector roll 4, prevent optical cable from beating.
Since the present invention forms elliptic pulley group, using the larger radius of curvature of ellipse to adapt to larger radius of curvature
Hawser keep hawser sliding in ellipse using the rotation of idler wheel simultaneously because elliptic pulley group is made of multiple idler wheels
It is free to slide in wheel group, it ensure that the working performance of pulley blocks, meanwhile, radius of curvature of the present invention is greatly and the diameter of pulley blocks is small,
