Abstract
The invention relates to a wheel structure for an uneven ground, which comprises a wheel disk, three layers of one-piece gears, racks and grounding legs. According to the wheel structure for the uneven ground, the defect that the length of a spoke rod in the prior art can not be changed is overcome. The wheel structure for the uneven ground can be used on an even road or a road with a slope and especially can be used for realizing the operation of going up or down steps or stairs easily under the traction of people. The labor intensity of the people is relieved.
Description
Technical field
The present invention relates to art of wheels, particularly relate to a kind of wheel construction for unfairness ground.
Background technology
At present, the wheel construction majority of all kinds of light hand-pulling carts is common circular wheel, although the dolly that circular ordinary wheel structure is installed can adapt to the road conditions in smooth or ramp, but under special road conditions, for example run into step or stair, need car to jump when upper and lower, just can not normally use, need abandon car and carry out the object on transport trolley by people.
In order to solve the problems of the technologies described above, currently available technology mainly adopts two kinds of special wheel constructions, and one is crawler type, and another kind is spoke wheel type.Crawler wheel structure in the time of stair activity and the contact surface of stair very little, only touch with the side edge of stair, therefore, less stable when operation, and the lift angle of existing residential houses stair is larger, is generally 28 °-34 °, therefore its safety performance is desirable not enough.Spoke wheel type wheel construction is mainly made up of axle bed, radiation support tube and scroll wheel etc., radiation support tube operated by rotary motion has multiple, this spoke wheel type wheel construction has solved the problem little with stair contact surface, in the time of stair activity, wheel contacts with stair plane, and therefore, its safety performance is better than crawler type, but practical effect is desirable not enough, and the subject matter that it exists is: the length of spoke bar can not be adjusted.As everyone knows, there is very large difference, the regulation according to GB50096-1999 " Code for design of dwelling houses ": stair step width is not less than 26cm, and step height is not more than 17.5cm in the size of existing stair.Regulation in JGJ48-88 " Store Building design regulation ": tread run is not less than 30cm, and step height is not more than 15cm.So the tread run of existing house and public place stair is 26-30cm, step height is 15-17.5cm.In the time changing in the step height of the stair scope at 15-17.5cm, if the length of spoke bar is constant, load gravity is likely between two spoke bar supporting-point, also be likely positioned at the outside of two spoke bar supporting-point, be positioned at the land outside of wheel of lower floor ladder, also likely with two spoke bars in spoke bar below coincide.When load gravity is between two spoke bar supporting-point time, motion is suitable for going upstairs, but the motion that is not suitable for going downstairs, in the time that load gravity is positioned at the outside of two spoke bar supporting-point, motion is suitable for going downstairs, but motion is not suitable for going upstairs, therefore, existing spoke wheel type wheel construction is owing to can not adapting to the stair of differing heights, in the process of stair activity, neither convenient operation, not laborsaving yet; Exactly because also the length of spoke bar can not be adjusted, even when existing spoke wheel type wheel construction is advanced between the identical stair of step height, its center of gravity can cause larger jolting because move up and down, and travels thereby dolly can not be stablized.
Summary of the invention
In order to solve the deficiency of above-mentioned technology, the invention provides a kind of reasonable in design, compact conformation, can be installed on the wheel construction on all kinds of light hand-pulling carts, this wheel construction can not only be walked level road, especially can easily tackle the unfairness such as step or stair ground.
