Background technique

At present, my country's civil construction engineering industry is developing rapidly, and the equipment used in civil construction engineering is also diverse, but it still faces challenges in many aspects, and it is necessary to find solutions that satisfy customers. The Chinese patent literature with application number: 201510045518.1 reports an electric double-deck trolley, the specific content is: an electric double-deck trolley, which includes a loading vehicle body, and the bottom of the loading vehicle body is provided with four wheels, A push handle is also provided on the described load vehicle body, an electric drive system is provided at the bottom of the described load vehicle body, an electric control operation panel is provided on the described load vehicle body, There is also a second loading platform on the top, the electric drive system is battery-driven, and the surface of the loading vehicle body and the second loading platform is provided with anti-slip rubber. Since the electric double-deck trolley of the present invention is provided with an electric drive system at the bottom of the trolley, electricity is used instead of manpower, and a second stage is set on the body of the trolley, which increases the weight of the load, thereby greatly improving The conveying capacity of the trolley is improved. The novel structure contains the advantages that the above-mentioned patents have, but the practicability of the above-mentioned patents is not high. To sum up, so I designed a new electric trolley for the construction site.

Contents of the invention

In order to solve the above existing problems, the utility model provides a new type of electric trolley for construction sites. The utility model is realized through the following technical solutions:

A new type of electric trolley for construction sites, including rear universal wheels, a vehicle frame, and a drive shaft. A drive shaft is provided at the left lower end of the vehicle frame; a rear universal wheel is provided at the outer end of the drive shaft; There is a motor; the left end of the motor is fixed with a kick brake device; the right end of the motor is provided with a storage battery; the upper end of the frame is equipped with a fixed bracket; The power control switch is connected; the upper end of the frame is provided with a carriage; the lower end of the frame is fixed with a brake; the right end of the frame is equipped with a front explosion-proof wheel.

As a further optimization solution of the utility model, the height and angle of the fixed bracket can be adjusted; the motor is installed at the left end of the frame; the inner end of the rear universal wheel is connected to the frame.

As a further optimization solution of the utility model, the upper end of the motor is provided with the fixed bracket; the iron speed control handle is connected to the power control switch through wires; the battery is connected to the motor through wires.

As a further optimization solution of the present utility model, there are two rear universal wheels; two front explosion-proof wheels; the kick brake device is connected to the brake through wires.

Compared with the existing technology, the beneficial effect of the utility model is that the new electric trolley for the construction site adopts the method of converting electric energy into mechanical energy, and the walking of the trolley can be realized without pushing or pulling hard by people. Use the handle to control the balance and walking speed of the trolley, which greatly reduces the labor intensity, thereby improving the work efficiency, no noise, no pollution, energy saving and environmental protection, and the overall structure is simple, the design is reasonable, the operation is simple, the practicability is high, and the production Low cost, suitable for application and promotion.
