Technical Field

The utility model relates to a handcart, specific saying so relates to an electronic small handcart of building site, and it combines together traditional building site's handcart and modern electric drive technique, makes workman greatly reduced intensity of labour when the handcart, and it mainly used uses when propelling movement gravel and sand cement on various building sites.

Background

The two-wheeled small cart is widely applied to building sites, and has the characteristics of low manufacturing cost, simple maintenance, convenient operation and light dead weight, can work in places where large motor vehicles are inconvenient to pass, and is very convenient to carry articles in short distance particularly. The traditional trolley is usually pushed to advance only by manpower, the pushing speed is low, the trolley is hard to use, the working efficiency is low, the working efficiency of the trolley is improved, and meanwhile, the labor intensity of workers can be reduced.

Disclosure of Invention

An object of the utility model is to overcome prior art not enough, provide an electronic small handcart of building site, this small handcart simple structure, convenient to use, low in cost is fit for transporting the heavy article of little volume at building site, can reduce workman's intensity of labour effectively and improve labor efficiency.

In order to achieve the above purpose, the utility model discloses a method is: an electric trolley for construction sites comprises a carriage, push rods, handles and an axle, wherein the carriage is formed by welding thin steel plates, the left side and the right side of the rear portion of the carriage are respectively welded with one push rod, the end portion of the right push rod is provided with one handle for adjusting the magnitude of driving current, the driving force is increased when the handle is rotated anticlockwise, the running speed of the trolley is increased, the end portion of the left push rod is provided with one handle for braking the trolley, the handle is rotated anticlockwise to brake the trolley in the process of running, a rotating support is arranged behind the lower portion of the carriage, the lower portion of the rotating support is provided with a steering wheel, the front of the lower portion of the carriage is provided with the axle, a direct current motor is arranged on a speed reducer in the middle of the axle, two ends of the axle are respectively provided with one wheel, a braking device is arranged in each wheel, an electric box is arranged behind the carriage, a storage battery and a current controller are arranged in the electric box, the axle is connected with the carriage through 4 connecting holes at two ends.

The utility model discloses a use method is: whether the storage battery connection meets the requirements is checked before use, then the handles are tightly held by two hands, the left hand slightly rotates the handles clockwise to ensure that braking is removed, the right hand slowly rotates the handles anticlockwise to gradually increase the driving force to enable the trolley to run, when braking is needed, the left hand rapidly rotates the handles anticlockwise to brake the wheels, and at the moment, the driving current of the motor is also automatically cut off.

The utility model has the advantages that: the device has the advantages of low manufacturing cost, simple maintenance, convenient operation and flexible steering, can work in places where large motor vehicles are inconvenient to pass, is very convenient particularly when carrying articles in short distance, can always keep stable operation even when driving on a road section with ascending and descending roads, and can effectively reduce the labor intensity of workers and improve the labor efficiency.
