Description
Technical field
The present invention relates to a kind of stairs-movers, for transporting cargo on stair.
Background technique
The structure of electric cart for going-up stairs generally comprises cross or Y shape wheel carrier, wheel carrier are fixedly connected with main shaft, and main shaft is by direct current
The vehicle frame of motor driven, main shaft and loading connects, and angle as defined in the every rotation of wheel carrier, electric cart for going-up stairs steps to a new level.For
For the different stair of various specifications, to avoid step-out, (definition of step-out is angle as defined in the every rotation of wheel carrier, and adjacent arm is not
Can be contacted with adjacent step), want the size of stairway step as needed to adjust the length of wheel carrier spoke before use, this is not square
Just it uses.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of intelligent electric stairs-mover, the arm for adjusting wheel carrier is not needed
It is long, it can also be used on the stair of various specifications.
The technical scheme is that a kind of intelligent electric stairs-mover comprising vehicle frame, wheel 2, main shaft 12, main shaft by
One direct current generator 14 driving, characterized in that main shaft both ends have been movably connected with wheel carrier 15, and wheel carrier is with three to six roots of sensation spoke
19, each spoke end is equipped with the first mandrel 3, and the middle part of each spoke is equipped with the second mandrel 5, is cased with wheel and first on the first mandrel
Gear 1, first gear is fixedly connected with wheel, and second gear 4 is cased on the second mandrel, gear wheel is fixedly connected on main shaft
6, first gear is meshed with the second gear, and second gear is meshed with gear wheel；The diameter of first gear is less than the straight of wheel
Diameter, the diameter dimension of wheel are less than the height dimension of stairway step, the size of the distance at center to the lateral wheel edge of wheel carrier
Slightly larger than the height dimension of stairway step, the number of teeth of first gear is less than the number of teeth of gear wheel；Electromagnetism is equipped in the outside of wheel carrier
