Wheel 29 is meshed.
When the utility model is used: counterweight is hung over into cotton rope one end, rotates the rear-wheel driving wheel 4 of rear-wheel, reversed band moving-wire
Rope is wound on roll 7 and starting axle sleeve 27, and the starting design of axle sleeve 27 has helical groove, keeps cotton rope recessed from relatively large radius
Slot is smoothly transitted on the roll 7 at small radii, and the design of starting axle sleeve 27 can resist biggish starting when trolley starting
Frictional resistance moment, and the lesser radius energy balancing trolley of roll 7 run when resistance to sliding square, and can make trolley at the uniform velocity grow away from
From around stake.After coiling, trolley is placed on the suitable position of starting point, discharges counterweight, the counterweight of whereabouts drives cotton rope, cotton rope band
Dynamic roll 7 rotates, and 7 one end of roll drives driving gear 5 to rotate, and the other end drives crank 25 to rotate.5 band of driving gear
Dynamic driven gear 29 rotates, and driven gear 29 drives hind axle 28 and rear-wheel driving wheel 4 to rotate, rear-wheel driven wheel 23 therewith with
Into trolley is to start to advance.The rotation of crank 25 drives bearing 22 thereon to slide in the sliding slot of crank set 24, thus band
Dynamic crank set 24 and slide rail 19 fixed thereto are moved forward and backward, and slide rail 19 drives 16 front and back of fine tuning front stall thereon
It is mobile, to drive the first bearing on fine tuning front stall 16 to slide in 13 sliding slot of swing rod, to drive 12 turns of front-wheel support
Dynamic, front-wheel 10 rotates with it, and realizes and turns to.Because driving gear 5 and crank 25 are fixed on 7 both ends of roll, while with coiling
Axis 7 rotates, so trolley advances, progress synchronous with steering continues to realize serpentine track around stake.
Because parts depreciation or frequent dismounting will cause the destruction to trolley assembly precision, Jin Erzao during trolley travelling
Deviation occurs at the center of the periodical pivot angle range of front-wheel 10 and deviates track, and this deviation can be accumulated gradually
Running track and the desired guiding trajectory deviation in turn resulting in trolley are increasing, cannot play the real standard of trolley, reduce ratio
Match achievement.Based on the situation, in debugging process, the tight fixed bolt 15 of fine tuning front stall 16 and slide rail 19 is first unclamped, then adjust
Save micrometer differential head 14.Differential head is adjusted if small wheel paths are to the left subtracts fine tuning front stall 16 at a distance from fine tuning back seat 17
Small, micrometer differential head 14 is adjusted if small wheel paths are to the right increases fine tuning front stall 16 at a distance from fine tuning back seat 17, and thousand points
Ruler differential head 14 must move fine tuning front stall 16 after adjusting withstand on one end of micrometer differential head 14 on fine tuning back seat 17,
The tight fixed bolt 15 for finally tightening fine tuning front stall 16 keeps it fixed with slide rail 19, can discharge trolley at this time, observe it
Running track continues to adjust if there is also deviation.Dichotomy can be used in adjustment process for the quarter of micrometer differential head 14
Degree is held, until the track for being adjusted to trolley reaches desired guiding trajectory.
