Description
Technical field
The utility model relates to a kind of transportation means, is specifically related to a kind of Electric hand cart, and its feature is that the position of wheel relative frame can motorized adjustment.
Background technology
Hand barrow is widely used in rural area and building site, is a kind of cheap, simple and reliable small-sized transportation device.But conventional hand barrow relies on manual work completely, operation intensity is very large, and transport capacity is very limited simultaneously.Although Electric hand cart obtains large development in recent years, because himself weight is comparatively large, objectively also significantly cannot reduce labour intensity, improve carrying capacity.
The utility model tries hard to solve labour intensity and this two problems of carrying capacity, proposes a kind of novel handcart based on Electric hand cart.
Summary of the invention
In order to reduce labour intensity, improve carrying capacity, the utility model provides a kind of and uses electrically operated hand barrow, and adopt steel framed structure, wheel position relative frame position can regulate in real time, selects wide-face wheel tire simultaneously, improves balance.
It is a kind of electric hand barrow that the utility model solves the technical scheme that its technical matters adopts, and mainly comprises vehicle frame 1, guide rail 2, wheel carrier 3, DC machine 4, change speed gear box 5, transmission shaft 6, main shaft 7, double-reduction gear 8, wheel 9, storage battery 10, wheel carrier adapter shaft 11, pull bar 12, leading screw 13, bearing 14, feed screw nut 15, worm gear 16, worm screw 17, miniature electric motor 18, brake 19, left control dial 20, right control dial 21, needle bearing 22.It is characterized in that: described wheel carrier 3 is contacted with guide rail 2 by needle bearing 22, described guide rail 2 is welded on vehicle frame 1, described wheel carrier adapter shaft 11 is connected with leading screw 13 with feed screw nut 15 by pull bar 12, described leading screw 13 is fixed by bearing 14 and vehicle frame 1, described leading screw 13 is connected with worm gear 16, described miniature electric motor 18 is fixed on vehicle frame 1, and engaged with worm gear 16 by worm screw 17, described left control button 20, right control dial 21 and brake 19 are arranged on vehicle frame 1, described DC machine 4, change speed gear box 5, transmission shaft 6, double-reduction gear 8, main shaft 7, wheel 9, storage battery 10 is integrated to be assemblied on wheel carrier 3.
Above-mentioned a kind of electric hand barrow, with storage battery 10 for propulsion source, drives wheel 9 to rotate by DC machine 4, controls wheel 9 and vehicle frame 1 relative position by miniature electric motor 18 simultaneously.
Whole hand barrow is under normal forward travel state, a leverage is formed: wheel is fulcrum along direct of travel, the center of gravity of car load and institute's cargo and the horizontal throw of wheel and gravity thereof produce moment, the horizontal throw of operator's both hands distance wheel forms corresponding moment to its applied force, two moment balances.The utility model is based on above-mentioned principle, and its principle of work is:
This hand barrow coordinates speed reduction gearing to make it advance by DC machine, and gait of march rotates vehicle frame right hand grip by operator and controls.To advance or under parked state, operator controls the position of wheel carrier relative frame by the rotor switch in vehicle frame left hand grip.Concrete mode is: the forward (oppositely) being controlled miniature electric motor by rotor switch is rotated, and power slows down via worm and gear and passes to leading screw, and the rotation of leading screw makes two feed screw nuts traversing, between the two every increase (reduction).The wheel carrier that pull bar makes it connect that moves laterally through of feed screw nut advances (retrogressing) along the direction of guide rail, thus controls wheel and move, and reaches the object of mobile whole leverage fulcrum.Design continuous setting range and be 0 to 20 centimetre, and the center-of-gravity position of car load and goods should within this scope.
The beneficial effect of a kind of electric hand barrow of the utility model is: utilize driven by power to replace manpower, the relatively adjustable of wheel position will significantly reduce operator's lifting hand barrow and keep the required power applied of balance simultaneously, operator's labour intensity is obviously reduced, operate more easy, carrying capacity significantly strengthens.
