The specific embodiment

Below in conjunction with accompanying drawing the utility model is further explained:

Referring to accompanying drawing, main shaft 22 is on the bearing 2 of bearing installation at base 1, and the tail end of main shaft 22 is connected with threaded shaft 4 through drive coupling; Said threaded shaft 4 also through bearing installation on bearing 2, said main shaft 22 is the polished rod axle, puts corresponding main gear that is provided with 12 and pinion 13 on it; Be meshing with each other through steering gear 14 between main gear 12 and the pinion 13; Be 14 whiles of steering gear and main gear 12 and pinion 13 engagements, being equipped with through interior male splines adapter sleeve on the main shaft 22 between said main gear 12 and the pinion 13 can be along main shaft 22 axially movable two-way cards wheel 24, when realizing that promptly two-way card wheel 24 can drive main shaft 22 rotations; Also can be along main shaft 22 axial two side shiftings; Said two-way card is taken turns the fixture block 25 of 24 two sides can be respectively 26 corresponding with the cutting ferrule of main gear 12 and pinion 13 inner faces (fixture block 25 can corresponding insertions cutting ferrule 26 in), also has annular driving lever groove 24.1 on the said two-way card wheel 24, in the upper end insertion driving lever groove 24.1 of driving lever 15; The lower end is sleeved on moving bar 16 and reaches on the driving lever guide rod 18 that laterally arranges with moving bar 16; Also be with spring 17 on the moving bar 16 of said driving lever 15 both sides, moving bar 16 two ends link to each other with the axle core 21 of both

sides electromagnet

19,20, and driving lever guide rod 18 two ends are installed on the bearing 2; Be with strand oscillator 5 on the said threaded shaft 4; The screw-internal thread fit of the outside thread of said threaded shaft 4 and strand oscillator 5 also is provided with on the said bearing 2 and passes strand oscillator 5 and threaded shaft 4 parallel guide rod 6, also is provided with the steel rope hole clipping 9 that is used to pass steel rope on the strand oscillator 5; Steel rope hole clipping 9 is by the draw-in groove that is arranged on two bidirectional slide wheels 11 on the strand oscillator 58 corresponding formation; Spacing top 7 is equipped with in the both sides of said strand oscillator 5, and the electromagnet of limit switch 10 corresponding control one sides of every side is housed respectively on the bearing 2 at said threaded shaft 4 two ends and spacing top 7 cooresponding limit switches 10.The actuating device that said driving main gear 12 rotates is not particularly limited, and preferably uses motor 3, and said transmission device does not limit especially yet, as adopting chain gear, belt-driving or other attainable various type of drive, preferably uses chain 23 to carry out transmission.Said limit switch 10 can be controlled

corresponding electromagnet

19,20 break-makes electricity through relay, to reach the purpose that traction driving lever 15 drives 24 liang of side shiftings of two-way card wheel.

Principle of work:

With reference to accompanying drawing; Motor 3 drives main gear 12 through chain drive and on main shaft 22, dallies; Drive simultaneously ingear steering gear 14 successively and rotate, because the effect of steering gear 14, make the rotation direction of rotation direction and main gear 12 of pinion 13 just in time opposite with pinion 13.Trigger a side electromagnet 20 energisings simultaneously through relay during startup, 19 outages of opposite side electromagnet make bar to electromagnet 20 1 side shiftings; Drive driving lever 15 to side shifting and push the spring 17 of homonymy, driving lever guide rod 18 be its guiding simultaneously, and then promotes two-way card and take turns 24 and move to main gear 12 directions; And cutting ferrule 26 clampings on the fixture block 25 that makes this side and the main gear 12; Like this, the rotational force of main gear 12 is passed to two-way card wheel 24 simultaneously, finally drives main shaft 22, threaded shaft 4 rotations successively by two-way card wheel 24; Because strand oscillator 5 spins axostylus axostyle 4 with spiral shell and is threaded; The rotation of threaded shaft 4 can make strand oscillator 5 front end (being left direction among Fig. 2) to threaded shaft 4 under the spacing of guide rod 6 and guiding move, and steel rope is moved to threaded shaft 4 front ends by strand oscillator 5 tractions through wire rope hole 9; Winch is worked simultaneously and is rolled steel rope, has realized the ground floor winding displacement on winch; When strand oscillator 5 goes upward to the 2 last times of bearing near threaded shaft 4 front ends in threaded shaft 4, cooresponding limit switch 10 is touched on the spacing top 7 in strand oscillator 5 left sides, and this limit switch 10 sends control signal and gives relay; Make electromagnet 20 outages, electromagnet 19 energisings, make under spring 17 cooperates, moving bar 16 is to electromagnet 19 1 side shiftings; Drive driving lever 15 to same side shifting; Moving driving lever guide rod 18 be its guiding simultaneously, and then promotes two-way card wheel 24 and move to pinion 13 directions, and makes the fixture block 25 of this side and cutting ferrule 26 clampings on the pinion 13; Like this; The rotational force of main gear 12 is passed to two-way card wheel 24 through steering gear 14, pinion 13, and has realized turning to of rotational force simultaneously, drives main shaft 22, threaded shaft 4 backward rotation through two-way card wheel 24; Strand oscillator 5 tail end (being right direction among Fig. 2) to threaded shaft 4 under the spacing of guide rod 6 and guiding moves; Steel rope is moved to threaded shaft 4 tail ends by strand oscillator 5 tractions through wire rope hole 9, and winch is worked simultaneously and rolled steel rope, has realized the second layer winding displacement on winch; When strand oscillator 5 goes upward to the 2 last times of bearing near threaded shaft 4 tail ends in threaded shaft 4; Cooresponding limit switch 10 is touched on the spacing top 7 on strand oscillator 5 right sides, and this limit switch 10 sends control signal and gives relay, makes electromagnet 20 energisings, electromagnet 19 outages once more; Make bar 16 to electromagnet 20 1 side shiftings once more; Repeat ground floor winding displacement process, so Zhou Erfu makes, and realizes the synchronous automatic winding displacement process of winch steel rope multilayer.
