Description of drawings:

Fig. 1 is a transmission device front view of the present invention, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the B-B cutaway view of Fig. 1, and Fig. 4 is big or small rope sheave drive mechanism schematic diagram.

The specific embodiment:

In conjunction with above accompanying drawing the present invention is elaborated, existing drawing-die forming device in drawing vibration tube and drawing-die group process because the position of steel wire rope on rope sheave is fixing, cause drawing-die group or draw vibration tube to wander off, need manually to correct, otherwise vibration tube and mould do not align with crowbar.Be head it off, two pairs of sheaves are set respectively, the a pair of drawing-die group that is used for, another is to being used for the tractor walking and drawing vibration tube, the edge of a sheave 30 in a pair of sheave is relative with the center between mould group, and another sheave 29 is relative with the center of marline wheel 28, and two sheaves of this a pair of sheave, 90 degree each other are provided with, what make steel wire rope moves towards to become 90 degree, in a side of big rope sheave same a pair of sheave 25,26 is set also.(referring to Fig. 4) this sheave structure has solved the problem that wanders off, the wander off another kind of technical scheme of problem of solution is, on a heel post of marline wheel 28 and big rope sheave 27, respectively be provided with a sheave that is rotatably assorted, one side outer rim of sheave is relative with the center between the mould group, and a side of another sheave is relative with big rope sheave center.But the deceleration of original worm gear drive case need change structure by gear-box solves.

In order to solve the deceleration of big or small rope sheave, design new gear-box, be provided with I axle 3, II axle 4, III axle 8 in it, be parallel to each other and 2,5 on equidistant 5 IV axles are parallel to each other and equidistant V axle 1 is connected (referring to Fig. 1) with five axles that shake respectively.I axle 3 be provided with a gear wheel that is connected 4 and pinion 3 respectively with an IV axle 2 on gear 12 and the gear wheel 11 on the II axle match, cylinder on the sliding sleeve 16 places the shift fork mouth of handle 6 lower ends, this sliding sleeve and 15 sliding joining of guide pillar, there is a blind hole 17 relative in the sidewall of sliding sleeve with radial hole on the sidewall, be provided with spring and pin in the blind hole, be axially arranged with three spacing pits in guide pillar body upper edge and pin matches, the guide pin bushing bottom is provided with driving lever and places in the cannelure on the big or small gear mass on the I axle, five IV axles respectively are provided with the identical and intermeshed gear of the number of teeth, gear 9 engagements (referring to Fig. 2) that these five gears are identical with five numbers of teeth on the V axle respectively.Pinion 10 engagements of rotational support on gear wheel on the III axle 20 and II axle, end tooth on the left and right sides both ends of the surface of the gear wheel on the III axle respectively with marline wheel shaft 24 and big sheave shaft 18 on clutch 23 end teeth match, crosspiece poking fork sleeve 21 sliding fitting on the guide pillar 22 on gear housing top, handle 7 lower ends place on the crosspiece poking fork sleeve wall the mouth in, the two ends of crosspiece poking fork bottom respectively have a driving lever 19 to place the cannelure (referring to Fig. 3) of big or small sheave shaft clutch.

Method of operating of the present invention is, in the time need carrying out next prefabricated board moulding behind prefabricated board of moulding, elder generation's control crank 6 breaks away from I axle gear wheel and IV shaft gear, this moment each vibration tube shake core stop the vibration, and the engagement of the gear wheel on pinion on the I axle and the II axle, pinion on the II axle and the engagement of III axle gear wheel, at this moment, motor 5 through twice deceleration after the rotating speed of III axle drop to the speed that is fit to pull out vibration tube and mould group, at this moment, operate another handle 7, make clutch on the big sheave shaft move with the III axle on the end tooth engagement of gear wheel, this moment, big rope sheave rotated, after tractor begins walking and vibration tube is pulled out from prefabricated board, handle this handle plate to opposite position, make clutch on the little sheave shaft move end tooth engagement with the III axle gear wheel other end, and clutch on the big sheave shaft and III axle gear wheel are thrown off, tractor stops, the marline wheel rotates mould group is broken away from from the prefabricated board of forming, vibration tube enters in the shaping mould simultaneously, after prefabricated board is thrown off by mould group, after handle 7 places neutral position, control crank 6 makes I axle gear wheel and the engagement of IV axle tooth, drives five axles that shake by the V axle and carries out second prefabricated board of vibrating forming.Because be provided with two guide wheels, pull rope is relative with the center of rope sheave all the time, has avoided wandering off, thereby drawing-die when group vibration tube inserts smoothly, and do not need artificial correction, owing to do not establish worm reducer, thereby this transmission structures is more simple, and cost is low, the shaping efficiency height.
