The specific embodiment:

Below, the technical characterictic to the utility model strand pulling machine steel strand propulsion system is further described in conjunction with the accompanying drawings and embodiments.

Embodiment:

A kind of strand pulling machine steel strand propulsion system, lead inlet pipe 1 by steel strand, regulating handle 2, with a driving gear 5, two idle pulleys 41,42, the gear pairs that constitute of each four mill pinion 31～38 up and down, steel strand delivery line 6, side panel 7, adjustable plate 8, junction plate 9, front and back plate washer 12,11 form, driving gear 5 be fixed on the side panel 7 and with two lower tooth supporting-point rollers 36,37 closely interlocks simultaneously, two idle pulleys 41,42 be separately fixed on the side panel 7 and respectively with lower tooth supporting-point roller 35,36 and 37,38 closely interlocks simultaneously, above four mill pinions 31～34 be contained in respectively on four pairs of junction plates 9, below four mill pinions 35～38 be contained on the side panel 7 by junction plate 9, on each mill pinion 31～38 semicircular groove is arranged respectively, above the axis of four mill pinions and following four mill pinions be in respectively on two horizontal planes, above the intersection point line of any two mill pinions and following corresponding two mill pinions and junction plate 9 form parallelogram, regulating handle 2 passes front baffle board 12 tops and is connected with adjustable plate 8, adjustable plate 8 links to each other with four pairs of junction plates 9 by four connecting rods 10, steel strand are led inlet pipe 1, steel strand delivery line 6 is separately fixed at front baffle board 12, on the back plate washer 11, preceding, back plate washer 11,12 are separately fixed between the panel of both sides.
