The rear axle shaft is equipped with a driven gear (the small gear). A middle shaft is equipped with a driving gear (the large gear). One end of the crank block is connected with a front shaft and the other end of the crank block is connected with a joint ball bearing. The other end of the push rod is connected with a front fork of the car by means of the joint ball bearing. The steering and classifying pitch-adjustment mechanism for the obstacle-surmounting carbon-free car has following advantages: the car adopts the combined mode of belt transmission and gear transmission, steady and noise-free transmission at high transmission efficiency is achieved; parts are protected against damage in case of overload; by adjusting the different positions of a belt on belt pulleys, different pile-winding periods are adjusted in a classified mode so that forward period of the car is accurately controlled and spacing distances among obstacles in various kinds are accommodated; and by adjusting length of a crank connecting rod, the range of oscillation of a front wheel can be accurately changed in order to control motion range and a walking trajectory of the car.
Description
Technical field
The present invention relates to obstacle detouring carbon-free trolley, be specifically related to turning to and classification distance adjustor of a kind of obstacle detouring carbon-free trolley
Background technology
As shown in Figure 1, require a given gravitional force, according to energy conversion principle, this gravitional force (falling head 400mm) can be converted to mechanical energy and can be used to drive dolly around stake walking, the mechanical device that turns to by design one.(contest specifies that the distance between two obstacle timbers is 700-1300mm).The great advantage of this obstacle detouring trolley body is exactly the front-wheel amplitude of oscillation that can adjust dolly according to the spacing of contest scene lot, and then the movement locus of adjustment dolly.
Existing dolly major part adopts cam, gear, crank rocker to drive steering mechanism as dolly, and wherein large, the precision of cam contour difficulty of processing is difficult to ensure; When next is the large Heavy Weight of cam volume, walking, resistance is large, and crank rocker has quickreturn characteristics, and dolly travel speed is uneven, thus track can be caused uneven.And carriage walking track is fixing, the run trace of dolly can not be adjusted according to the change of obstacle spacing.Also some mechanism is heavier, not only increases the quality of dolly own, also add the loss of energy in motion process, makes it not complete match.
Summary of the invention
Order ground of the present invention is the shortcoming that will overcome above-mentioned technology, provides the obstacle detouring carbon-free trolley that a kind of structure is simple, processing and fabricating is easy, cost is low, lightweight, the speed of travel even and can carry out classification adjustment according to obstacle spacing and turn to
Technical solution of the present invention is: on hind axle, install pinion, axis is installed gear wheel and small belt pulley, the winding slot of coiling is had in the middle part of axis, front axle is provided with big belt pulley and crank block, crank block is connected with crank rocker by joint ball bearing, and crank rocker is connected with dolly front fork by push rod.
Wherein, dolly utilizes joint ball bearing connecting crank rocking bar, crank block has crank chute, is changed the front-wheel amplitude of oscillation of dolly by mobile front axle in the position of crank chute, and belt transmission can be coordinated to adjust the movement locus of dolly more accurately.
Wherein, dolly adopts belt transmission, car is equipped with two belt shafts, every root belt shaft is equipped with belt pulley, large small belt pulley there are respectively 7 belt grooves, by changing belt in the position (namely different grooves) of belt pulley, thus regulate the front-wheel amplitude of oscillation of dolly, and then control the running orbit of dolly, make dolly can strain the change of various obstacle spacing.
Wherein, the hard-over by changing front-wheel deflection determines the track of carriage walking: when the hard-over of Trolley front wheel is 30 degree, carriage walking track is " S " type; When Trolley front wheel hard-over is 120 degree, carriage walking track is for falling " 8 " type.
During carriage walking, fine rule makes central axis by winding slot, and axis drives gear wheel and small belt pulley, and gear wheel engages with the pinion on hind axle and drives rear wheel; Meanwhile, the small belt pulley on axis is by belt drive big belt pulley, and big belt pulley drives front axis, thus drives crank block to rotate, and then push rod promotes front-wheel front fork, and dolly turns to.
The present invention has the following advantages: 1, trolley body adopts 2A12 duralumin, hard alumin ium alloy thus alleviates the overall weight of mechanism, reduces the energy loss that frictional force is brought, and good integrity, easily processes, reduce holistic cost simultaneously; 2, dolly adopts the transmission mode that belt transmission and gear drive combine, and stable drive noiseless, transmission efficiency is high, can ensure that instantaneous transmission ratio is constant, and part also can be protected during overload not to be damaged.3, mechanism of the present invention is simple, easy to operate, with low cost; 4, regulate the position of belt between belt pulley (i.e. naughty trough of belt), gradable adjustment different around the stake cycle, and then accurate control Plantago minuta line period adapt to various obstacle spacing; 5, regulate crank link length, the size of the front-wheel amplitude of oscillation can be changed accurately to control the range of movement of dolly.
