Specific embodiment
For content of the invention, feature and effect of the present invention can be further appreciated that, hereby enumerate following examples, and coordinate accompanying drawing
Describe in detail as follows.
With reference to Fig. 1 to Fig. 6, the structure of the present invention is explained in detail.
This carbon-free voluntarily obstacle detouring dolly includes car frame 5, and the upper end of car frame 5 is provided with drive mechanism 2, driver
The upper end of structure 2 is provided with energy transfer mechanism 1, and the front end of drive mechanism 2 is provided with drive mechanism 4, the front end peace of drive mechanism 4
Equipped with steering mechanism 3；Energy transfer mechanism 1 is passed through drive mechanism 2 and is installed with drive mechanism 4 and steering mechanism 3 mechanical engagement.
Further, the upper end of described support 2 is provided with trapezoidal wheel 1-2, and the lower end of support 2 is provided with fixed pulley 1-3.
Further, described drive mechanism 2 includes the small pulley 2-1 connecting by belt and big belt wheel 2-2.
Further, the upper end of described steering spindle 3-2 is provided with steering arm 3-1, and the lower end of steering spindle 3-2 is provided with turning sleeve
Cylinder 3-3, the outside turning to sleeve 3-3 is provided with locking nut 3-4.
Further, the front end of described car frame 5 is provided with front-wheel 4-1, and the rear end of car frame 5 is provided with trailing wheel 4-2；
The upper end of car frame 5 is provided with cylindrical cam 4-3, and the upper end of cylindrical cam 4-3 is provided with litter 4-4, the middle part of litter 4-4
Crossbeam slide block 4-5 is installed.
With reference to operation principle, the structure of the present invention is further described.
Energy transfer mechanism 1 realizes the kinetic energy that the potential energy converting and energy that weight falls becomes dolly to move ahead, and overcomes friction work.Pass
Motivation structure 2 is that power and motion are delivered in steering mechanism 3 and drive mechanism 4, makes dolly by certain distance curve driving
Farther.Convert rotational motion is to meet the periodic wobble requiring by steering mechanism 3, drives deflecting roller left-right rotation thus reality
The function of avoidance of now turning round.Drive mechanism 4 makes cylindrical cam 4-3 obtain continuous or discrete any expected reciprocating motion.Little
Vehicle carriage 5, as the installation foundation of other mechanisms, bears constant weight and carries the weight falling.Support 2 is arranged on dolly car
On frame 5, fixed pulley 1-3 is installed in support 2 upper end；There is helical curve wire casing on trapezoidal wheel 1-2 surface for being wound around cord, simultaneously conduct again
Trailing wheel 4-2 and the installation axle of small pulley 2-1.Cylindrical cam 4- with certain curved slot is installed on big belt wheel 2-2 installation axle
3, the groove on cylindrical cam 4-3 is coordinated with cam slide, drives steering arm 3-1, steering spindle 3-2, drives steering front wheel 4-1 real
Turn now to.Car frame 5 is manufactured using plexiglas.Wherein triangular structure is compact but can not carry the weight falling
Thing, rectangular configuration steadily but waste of material and increase dolly deadweight, and triangle and rectangle is comprehensive can assemble triangles and square
The advantage of shape turn avoid major defect simultaneously, therefore selects triangle and rectangle comprehensive.
Fixed pulley 1-3 is installed in support 2 upper end, and weight is propped.There is helical curve wire casing on trapezoidal wheel 1-2 surface, for being wound around
Cord.The design of trapezoidal wheel 1-2 achieves the starting of dolly and falling from low speed of weight to slowing down, and reduces and damages because of collision
The energy losing.When initial, the radius of gyration of main wheel is larger, and starting torque is big, favourable starting.After starting, main wheel radius becomes
Little, rotating speed improves, and torque diminishes, and dolly uniform motion after resistance balance.When weight away from dolly close when, trapezoidal wheel 1-2's
Radius diminishes again, and the pulling force of rope is insufficient to allow the 1-2 uniform rotation of trapezoidal wheel, but the inertia due to weight, still can slow down
Decline, the radius of main wheel diminishes, total rotating ratio improves, dolly is slow to slow down until stopping, and thing block stops falling, and just contacts
Dolly.Mounting bracket 2 is done on support 2, fine rule is wound on trapezoidal wheel 1-2, fine rule other end connects weight, by fixed pulley 1-3
With support 2, weight is suspended on above dolly, during weight-drop, drives trailing wheel 4-2 to rotate.
Drive mechanism 2 is that power and motion are delivered in steering mechanism 3 and driving wheel, makes dolly bent by certain distance
It is farther that line travels.Have that structure is simple due to small pulley 2-1 and big belt wheel 2-2, stable drive, cheap buffering absorbing etc.
Advantage, through considering, mechanism adopts V belt translation as drive mechanism 2.Turn to and machined the circular arc of r20 to increase at wheel rim
Plus the engagement capacity on deflecting roller and ground, turning support machined screw thread to adapt to the needs of different wheelbases.
Steering mechanism 3 is the key component of this volume the car design, directly decides the function of dolly.Steering mechanism 3 is similarly
Need to reduce as far as possible friction energy-dissipating, structure is simple, also needs to special kinetic characteristic simultaneously.Rotary motion can be turned
The cycle backswing turning to satisfaction requirement is moved, and drives deflecting roller left-right rotation thus realizing the function of avoidance of turning round.
Drive mechanism 4 is cylindrical cam 4-3 mechanism, because cylindrical cam 4-3 has certain curved profile or groove
Component, when it moves, can make driven member obtain continuous or discrete any expected reciprocating motion by higher pair contact.Only need
Design suitable cylindrical cam 4-3 profile, driven member just can be made to obtain arbitrary desired movement, and structure is simple, compact, set
Meter is convenient.There is the hidden danger of upset in view of cam slide in motor process, employ double slide bar arrangements, also improve simultaneously
Its kinematic accuracy.
The speed of drive mechanism 4 inboard wheel in car steering procedure is less than outside, therefore needs to use differential structure, this dolly
Structure simply to realize differential hence with unilateral bearing.
Car frame 5 without bearing very big power, required precision low it is contemplated that weight processing cost etc., support 2 is using tree
Fat glass processing is fabricated to.Wherein triangular structure is compact but can not carry the weight falling, rectangular configuration steadily but material is unrestrained
Take and increase dolly deadweight, and the advantage of triangle and rectangle comprehensive energy assemble triangles and rectangle turn avoid mainly simultaneously
Shortcoming, therefore selects triangle and rectangle comprehensive.
The above is only to presently preferred embodiments of the present invention, not the present invention is made with any pro forma restriction,
Every technical spirit according to the present invention, to any simple modification made for any of the above embodiments, equivalent variations and modification, belongs to
In the range of technical solution of the present invention.
