Description

Track type cement concrete material evener

The utility model is a kind of electro-mechanical transmission, and Hang Zou machinery is mainly used in the material spreading construction in the cement concrete road in orbit.

At present, at home in the cement concrete road construction, all be that manpower carries out the operation of concrete spreading, promptly when dumper is discharged at material on the upright roadbed that template arranged in both sides, with manually material being let go, so not only time-consuming but also effort, and the top layer is difficult to accomplish uniformity, makes troubles for the back working procedure.Abroad, as the Germany, have a kind of with internal combustion engine-hydraulic drive, Hang Zou refiner in orbit.Though this machinery has solved the problem of letting material with manpower go, but it is higher that the manufacturing technology of this machinery requires with cost, inconvenience is adjusted and maintenance, especially before ought not starting, the adjustment of groundwork mechanism is difficult to realize, and in general non-hydraulicdriven machinery, the lifting of machine complete machine is difficult.

The purpose of this utility model is exactly that refiner to West Germany improves, internal combustion engine-hydraulic drive that the change refiner props up leg mechanism is the electro-mechanical transmission, be convenient to the adjustment and the maintenance of refiner operating mechanism, and all are adjusted and whether machinery starts irrelevant, and cost reduces greatly, is convenient to penetration and promotion.

Such as Fig. 1,2, be installed with decelerator 4 in frame 13, electric control box 5, movable motor 6, reel motor 11, roll device 12 etc., frame 13 two ends are connected with two supported boxs 7 with bolt by some flanges 15, increase or reduce the number of flange 15, the utility model is increased or minimizing work brightness, the utility model working width is adjustable from 2.5M～4.5M; The inboard of two supported boxs 7 and dolly crossbeam 14 are bolted, and coaster 3 is installed on the dolly crossbeam 14. Coaster 3 moves back and forth at dolly crossbeam 14 and controls by reel motor 11 and roll device 12. The lower end of coaster 3 is connected with bolt with screeding device, screeding device is groundwork of the present utility model mechanism, it is by common electric machine 16, decelerator 17 and scraper plate 2 form, screeding device can automatically commutate 360 ° of rotation 90 ° and continuous rotations, it with the running of reel motor 11 and roll device 12 and coaster 3 in the lump in 14 reciprocating motions of dolly crossbeam. In 360 ° of scopes, rotate as required simultaneously, movable motor 6 drives reduction box 4 and drives walking driver gear 18 motions through the chain transmission mode of routine, walking driver gear 18 and driven pulley 19 usefulness axles are installed on the leg mechanism 9, floating template 20 is housed on the wheel shaft of walking driver gear 18, and material spreads out when preventing scraper plate 2 work. Regulating electric machine 10 is fixed by bolts to the inboard of supported box 7, and it is used for regulating supporting leg The lifting of mechanism. In the utility model when work,, walking driver gear 18 and driven pulley 19 backhaul row two templates 1, and scraper plate 2 is at traverse motion, and can automatically rotate, and material is evenly distributed on the roadbed in two templates 1.

The utility model key component is the speed reduction gearing of a leg mechanism 9, (Fig. 3 has provided the structural representation of the utility model one side leg mechanism for its syndeton such as Fig. 3, opposite side is fully identical), front leg strut 21 and rear support leg 22 are hinged by the two ends of bearing pin 23 with supported box 7 respectively; One end of front screw 24 is installed with camshaft 26, and camshaft 26 is hinged with front leg strut 21; One end of rear screw rod 25 has a plush copper, and it matches with the recess of rear screw rod connector 27 1 ends, and existence one is moved and paid between them, and is connected by coupling nut 28. Be that differential thread connects between so rear screw rod 25, rear screw rod connector 27, coupling nut 28 threes, in order to remedy the error of low required precision in the actual fabrication, so that forward and backward supporting leg 21,22 is swung energy unanimously. The walking wheel that guarantees complete machine is in the same plane. The other end of rear screw rod connector 27 also is installed with camshaft 29, and this camshaft 29 is hinged with rear support leg 22. The other end of the other end of front screw 24 and rear screw rod 25 is relative to be movably linked together them side by side and with nut body 30, and nut body 30 is fixedly connected with worm gear 32 by key 31, and worm gear 32 is meshed with worm screw 33; Worm screw 33 is special, and it can positive and negatively turn round, and as shown in Figure 4, its left end is hollow, is processed with the hole 34 and the keyway 35 that match with regulating electric machine 10 among Fig. 1, is connected with the rotating shaft of regulating electric machine 10; The right-hand member of worm screw 33 is processed into square spigot, is inserted in from the adjusting hole 8 of supported box 7 when confession is manually adjusted and shakes handle usefulness (such as Fig. 1). In Fig. 3,4, centripetal thrust force type bearing 36 is used for supporting radially and axial load; Spherical self-aligning bearing 37 is to bear axial load, and makes worm screw 33 be convenient to assembling; Nut 38,39 only plays the location and bears axial load, pressure roller 41,42 worm gear 32 or centripetal thrust force type bearing 36 To be used for respectively radial load on balance front screw 24 and the rear screw rod connector 27. When with regulating electric machine 10 or when shaking handle and driving worm screw 33, drive worm gear 32 rotations, nut body 30 is together rotated. The thread that different rotation directions are arranged in the inner chamber of nut body 30, drive front screw 24, rear screw rod 25 and rear screw rod connector 27 and coupling nut 28 thereof and make together rectilinear motion, the camshaft 29 that makes the camshaft 26 of front screw 24 1 ends and rear screw rod connector 27 1 ends rotates voluntarily around the hinge axes between itself and front leg strut 21 and the rear support leg 22 respectively, makes simultaneously front leg strut 21 and rear support leg 22 realize swinging around its hinging pin shaft 23 with frame 13. Complete machine itself just obtains the elevating movement with respect to ground thereupon. When making separately an end supporting leg lifting, just form certain gradient, corresponding with crown slope. Adjustment by to a leg mechanism can make complete machine be suitable for from any duty between 10～40cm thickness, 0～6% crown slope.

The utility model can be saved manpower in a large number.Improve labour intensity, improve the uniformity consistency of refining speed and refining, can realize that according to the designing requirement of road layering paves, stepless adjustment thickness, the stepless adjustment road camber gradient does not have specific (special) requirements to the both sides formwork erection.The utility model and external internal combustion engine--the refiner of hydraulic transmission mode is compared, and it is low that it makes required precision, is convenient to make, and is with low cost, and is easy to adjust and realizes control automatically.Especially when complete machine does not start, also can manually adjust the height and the gradient of the groundwork mechanism of complete machine, in addition, the utility model maintenance is also more convenient.

Embodiment: to frame the utility model on track template 1, regulate motor 10 coarse adjustment and manually accurately adjust height and the gradient that a leg mechanism 9 requires to road design by two earlier, when the cement concrete material that needs making is unloaded to two templates 1 by other vehicle.Can start the utility model advances or retreats or pause.Start reel motor 11 simultaneously, make screeding device enter the working in reciprocating mode state.When coaster 3 walked near a side template 1, scraper plate 2 automatic half-twists returned opposite side template 1.And so forth.When the utility model front solid accumulation is higher, can operate the utility model and rise, perhaps make scraper plate 2 enter continuous rotation status simultaneously in coming and going, to reduce resistance, cloth is finished the refining work of cement concrete rapidly.
