As Fig. 1, shown in 2, the utility model is by body 33, be installed in the guide rail 3 on the body, the rammer that moves up and down along guide rail by guide wheel 21, be installed in the motor 46 on the body, the reductor 16 that is connected with motor by belt pulley 43 and belt 41, be arranged on upper sprocket wheel 8 and lower sprocket 15 on the body, act on chain 14 compositions that make the motion of rammer body on the rammer head hook 13 by the major axis of installing on the chain 23, sprocket wheel 15 is packed on the output shaft of reductor, and be connected with the sprocket wheel 8 that is installed on the body by bearing 9 by suit chain 14 thereon, bearing 9 is by

bolt

10,11,12 are installed on the body; On another output shaft of reductor, also be fixed with drive 42, drive 42 again be packed in power transmission shaft 35 on drive 40 be connected, drive 40, drive 42 are a kind of sprocket wheel, be connected by chain between them, power transmission shaft 35 is connected with the road wheel 37 that is installed on the body by bearing 34 again.

As shown in Figure 2, be connected by jaw clutch between the road wheel 37 that is installed in power transmission shaft 35 two ends and the power transmission shaft two ends, wherein be installed between movable half-clutch device 38 on the power transmission shaft and the power transmission shaft to being slidingly connected, and by handle 44 by control lever 45 can control shift fork make movable half-clutch device move vertically with the road wheel combination with separate, back-moving spring 39 can interact to control this clutch work with handle, by control left and right sides handle, can reach make about two clutch separation and combination, the turning in the time of when a side clutch separates in conjunction with opposite side, can realizing the machine walking.

As Fig. 3, shown in 4, in reductor 16, power shaft 26 is a worm shaft, be meshed with the worm gear 27 on being installed in power transmission shaft 25, with the coaxial mounted gear 28 of worm gear again by power being exported by the output shaft II with the engagement of another gear 21, drive sprocket 15 drives the rammer head and moves upward, after the rammer head moves to the upper sprocket wheel position, because of the chain movement track changes, therefore the major axis of installing on the chain 23 is separated with rammer head hook 13, make the rammer body do the movement of falling object, ground is tamped, the major axis of installing on the chain 23 is when ramming head hook 13 and contact once more, and chain then drives once more by a major axis 23 and an interaction of ramming head hook 13 and rams head and move upward, and this motion back and forth constantly can be finished the Ramming operation to ground.Gear 21 and output shaft II are for being slidingly connected, and gear 21 slides on the output shaft II by shift fork 17, the combination of realization and gear 28 with separate, thereby the motion of control sprocket wheel, stir shift fork gear 21 is separated with gear 28, promptly sprocket wheel is in neutral position, rams head and quits work.Gear 20 on the power transmission shaft 25 is meshed with gear 29 on the power transmission shaft 24 again, gear 30 on the power transmission shaft 24 is meshed with gear 31 again, gear 31 is meshed with gear 32 on the output shaft 1 again, drive drive 42 motions by output shaft 1, this drive is a sprocket wheel, realize the purpose that ground-engaging wheel 37 is walked by this sprocket wheel chain movement, wherein also be provided with driven pulley 36 at body; For being slidingly connected, gear 32 can slide on output shaft 1 by shift fork 22 between gear 32 and the output shaft 1, when shift fork handsetting gear 32 with after gear 31 separates, be that gear 32 is in neutral position, unpowered output this moment, road wheel is not walked, and whole equipment does not carry out walking movement.

As shown in Figure 1, with sprocket wheel 8 co-axially fixed same rotating shafts 7 on ratchet 6 also is installed, corresponding ratchet is equipped with ratchet 5 by axle 4 on body, can control sprocket wheel by the ratchet 5 and the interaction of ratchet 6 and only rotate to a direction, thereby guarantee to ram the safety of head in motion process.
