Three, utility model content:
The utility model is at the prior art deficiency, a kind of power transport trolley that can speeling stairway is proposed, rotate by the motor drives axletree, driving equal circumference well-distributed trundle is stepped on successively and is stepped to a new level, realize the heavy burden speeling stairway, simple in structure, easy to use, carrying finishing material and big part furniture or household electrical appliance use when being fit to very much not have the floor finishing of elevator or removal of home.
The technical scheme that the utility model adopted:
The motor-driven transport trolley of a kind of stair climbing, contain compartment and car bar, the compartment is movably arranged on the axletree by link span, the stair climbing wheel that described axletree two ends fixed installation star distributes, bottom outside the compartment or one side are installed with DC machine and storage battery, worm gear, worm gearing that the vertical intersection with axletree of the output shaft of described DC machine is set to cooperatively interact are provided with master cock control linkage storage battery and DC machine in described car bar up knob position.
The motor-driven transport trolley of described stair climbing, wherein the stair climbing wheel that distributes of star contains three, four or five spokes, and each spoke end all is equipped with a rubber wheel, and to be that the center of circle is uniform with the axletree be installed on the same circumference described rubber wheel.
The motor-driven transport trolley of described stair climbing, be provided with rubber wheel brake control mechanism, described rubber wheel brake control mechanism comprises the brake control cam that is located at link span lower end and axletree junction and is located at brake control stalk and retracing spring on each spoke that described brake control stalk is controlled under the camming action in brake and held out against rubber wheel.
The motor-driven transport trolley of described stair climbing is removed the arc line type groove that brakes inwardly vertically being provided with bottom of rubber wheel brake control cam; Two perhaps adjacent therein rubber wheels its cooresponding two control stalks when same horizontal surface lands are provided with the arc line type groove of removing brake with the corresponding contact site of controlling cam that brakes, the brake control stalk loosens rubber wheel when entering arc line type groove center under action of reset spring, removes brake.
The motor-driven transport trolley of described stair climbing, being provided with a spacing master cock with described master cock parallel connection is fixed on the link span, correspondingly with described spacing master cock on spoke, be provided with one and trigger part, vertically land or wherein adjacent two rubber wheels described triggering part when same horizontal surface lands triggers spacing master cock when one in the rubber wheel.
Useful good effect of the present utility model:
1, the motor-driven transport trolley of the utility model stair climbing, by adopting storage battery and DC machine and corresponding worm gear, the worm gearing that is provided with, that has realized transport trolley cleverly climbs the building shipping goods, simple in structure, have more value of service, can carry heavier goods or furniture, household electrical appliances etc., reduce user's labour intensity, improve work efficiency.
2, the motor-driven transport trolley of the utility model stair climbing is easy to use, safe, flexible operation.By design rubber wheel and brake control mechanism, rubber wheel does not rotate during stair climbing, has strengthened usage safety performance; When using on the level land, the brake control mechanism automatically terminates brake control, and the rubber wheel that lands can rotate flexibly, as common hand barrow, can push away, draw, and turns, and is easy to use.
3, the motor-driven transport trolley of the utility model stair climbing, by circuit control cleverly and Design of Mechanical Structure, automatically terminate rubber wheel brake and location in the time that the level land can being realized, make that no matter transport trolley is to travel and can operate steadily in speeling stairway or level land, has further guaranteed the safety of shipping goods.
Four, description of drawings:
