Side is mobile；And link block can be simultaneously along the first guide groove towards a sidesway of rotating wheel side-sway during moving backward
It is dynamic；I.e. on the one hand link block moves backward, on the other hand can be mobile towards the side of rotating wheel side-sway；Link block movement will band
Dynamic fixing sleeve is mobile；Fixing sleeve is mobile to drive fixed hub mobile；Fixed hub is mobile to drive first rotating shaft mobile；First rotating shaft
It is mobile to drive connection square mobile；Connection square is mobile just to will drive Wheel mounting bracket movement；Wheel mounting bracket movement passes through vehicle
Taking turns fixing axle drives rotating wheel mobile；I.e. rotating wheel can move backward while swinging, while can also be towards rotating wheel side-sway
Side it is mobile；Protrusion barrier is bypassed by three mobile superpositions of rotating wheel；Prevent the process protrusion barrier of rotating wheel
Shi Fasheng vibration；The effect of the first limit film and the second limit film is to prevent rotating wheel from first rotating shaft being driven to swing in the present invention
Cheng Zhong makes rotating wheel lose rotating function because the angle of rotating wheel side-sway is excessive；The effect of scroll spring is to work as rotating wheel
When breaking the barriers, rotating wheel can be made to be restored to original state by scroll spring；The effect of return spring is, so that
The second mobile guide block occurs when rotating wheel breaks the barriers can be restored to original position；I.e. link block is restored to originally
Position；I.e. rotating wheel is restored on original position；The effect of telescopic rotating shaft is on the one hand can to transmit second in the present invention
On the other hand the rotatory force of bevel gear and third hand tap gear can prevent the by telescopic rotating shaft in moving process when link block
Two bevel gears and third hand tap gear interfere, and influence limit plate；The effect of telescopic shaft is on the one hand can to transmit the 4th cone tooth
On the other hand the rotatory force of wheel can prevent third hand tap gear and the 4th from boring tooth in moving process when link block by telescopic shaft
Wheel interferes, and influences limit plate.
Relative to traditional cart platform technology, the universal wheel that the cart platform that the present invention designs uses can be according to obstacle
Object adjusts universal wheel, so that universal wheel can move backward while swinging, while can also side-sway；It is transported by the superposition of universal wheel
It moves to bypass protrusion barrier；Prevent cart platform by shaking when protrusion barrier.
