Description
Technical field
The present invention relates to obstacle detouring carbon-free trolley, and in particular to a kind of steering of obstacle detouring carbon-free trolley and classification distance adjustor
Background technology
As shown in Figure 1, it is desirable to a given gravitional force, according to energy conversion principle, design one kind can be by the gravitional force
(falling head 400mm) is converted to mechanical energy and can be used to drive dolly around stake walking, the mechanical device turned to.(contest is provided
The distance between two obstacle timbers are 700-1300mm).The great advantage of the obstacle detouring trolley body is exactly can be according to contest
The spacing that scene is drawn lots adjusts the front-wheel amplitude of oscillation of dolly, and then adjusts the movement locus of dolly.
Existing dolly largely drives steering mechanism, its cam wheel using cam, gear, crank rocker as dolly
Wide difficulty of processing is big, precision it is difficult to ensure that；Next to that resistance is big when the big weight weight of cam volume, walking, crank rocker has anxious
Return characteristic, dolly travel speed is uneven, so as to track can be caused uneven.And carriage walking track is fixed, it is impossible to
The run trace of dolly is adjusted according to the change of obstacle spacing.Also some mechanisms are heavier, not only increase dolly
Quality itself, also add the loss of energy in motion process, prevent it from completing match.
The content of the invention
Be the mesh of the present invention to overcome the shortcoming of above-mentioned technology there is provided one kind is simple in construction, processing and fabricating easily, cost
Low, the lightweight, speed of travel is uniform and the obstacle detouring carbon-free trolley of regulation and steering can be classified according to obstacle spacing
The present invention technical solution be：Little gear is installed on hind axle, installs big on the axle with 7 groove belt pulleys
Dynamic groove in the middle part of gear, the axle with 7 groove belt pulleys, is provided with conical belt wheel and slide crank with 7 grooves on front axle
Block, crank block is connected by joint ball bearing with crank rocker, and crank rocker is connected by push rod with dolly front fork.
Wherein, dolly utilizes and is provided with crank chute on joint ball bearing connecting crank rocking bar, crank block, before movement
Axle changes the front-wheel amplitude of oscillation of dolly in the position of crank chute, and belt transmission can be coordinated more accurately to adjust the fortune of dolly
Dynamic rail mark.
Wherein, dolly, which is used, is equipped with two root skin tape spools on belt transmission, car, be equipped with every root skin tape spool on belt pulley, axle 4
Belt pulley and conical belt wheel on have 7 belt grooves respectively, by changing belt 15 between the different slots of conical belt wheel 13
Position so that the front-wheel amplitude of oscillation to adjust dolly, and then control the running orbit of dolly, dolly is strained between various obstacles
Away from change.
Wherein, the track of carriage walking can be determined by changing the hard-over of front-wheel deflection:The maximum of Trolley front wheel
When corner is 30 degree, carriage walking track is " S " type；When Trolley front wheel hard-over is 120 degree, carriage walking track is
" 8 " type.
During carriage walking, dynamic trough 5, which provides power, rotates the axle 4 with 7 groove belt pulleys, the axle with 7 groove belt pulleys
Gear wheel is driven, gear wheel engages to drive rear wheel with the little gear on hind axle；At the same time, with 7 groove belt pulleys
On small belt pulley the conical belt wheels of 7 grooves is carried by belt drive, conical belt wheel with 7 grooves drives front axis,
So as to drive crank block to rotate, and then push rod promotes front-wheel front fork, and dolly is turned to.
The present invention has advantages below：1st, trolley body uses 2A12 duralumin, hard alumin ium alloys to alleviate the entirety weight of mechanism
Amount, reduces the energy loss that frictional force is brought, while good integrity, easy processing, reduce holistic cost；2nd, dolly uses skin
The transmission mode that V belt translation and gear drive are combined, stable drive noiseless, transmission efficiency is high, can guarantee that instantaneous transmission ratio is permanent
It is fixed, can also it protect part without damage during overload.3rd, mechanism of the present invention is simple, easy to operate, with low cost；4th, regulation belt exists
Position (i.e. naughty trough of belt) between belt pulley, gradable regulation is different around the stake cycle, and then accurate control Plantago minuta line period
And adapt to various obstacle spacings；5th, crank link length is adjusted, accurately can change the size of the front-wheel amplitude of oscillation to control dolly
Range of movement.
