Embodiment Construction

[0046] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] The main design principle of the present invention is to provide power for the traveling mechanism by using a fuel engine to burn fuel, and drive the generator to generate electricity as the energy supply source of the energy storage unit. High power operation for effective power supply. If it is not in the driving state, but needs to be charged, the fuel engine can be controlled to drive the generator to generate low-power power, so as to accumulate and charge the energy storage unit.

[0048] Please combine figure 1 , figure 2As shown, the energy supply method of the mobile engineering machinery of the present invention includes the following steps: a, using the fuel engine 111 to burn fuel oil to provide power for the traveling mechanism 1, and when driving, the fuel engine 111 drives the generator 112 to generate...

Abstract

The invention provides a power supply system for a mobile type engineering machine. The power supply system supplies power to a running mechanism by a fuel engine, drives a generator to generate electricity, charges an energy storage unit, supplies electric power to an operating mechanism by using the energy storage unit as a power supply source, and, when the running mechanism stop running, also can drive the generator to generate small-power electricity by controlling the rotation speed of the fuel engine so as to continuously charge the energy storage unit. The invention also provides a power supply method for the mobile type engineering machine. When the power supply method and the power supply system of the invention are used, the energy storage unit supplies the electric power to the operating mechanism, so that generation power can be reduced in operation considerably, over 40 to 60 percent of fuel can be saved, emission of pollutants can be reduced, and obvious social and economical benefit is created.

Description

technical field [0001] The present invention relates to the energy supply technology of engineering machinery, and more specifically, relates to an energy supply method and system for mobile engineering machinery. Background technique [0002] There are many types of mobile construction machinery, including excavators, shovel trucks, concrete mixer trucks, rock drilling rigs, crane trucks, dump trucks, etc., which are widely used in construction, water conservancy, electric power, roads, mines, ports and national defense and other engineering fields. see figure 1 As shown, at present, the common energy supply method of mobile construction machinery is: when driving, the fuel engine is used to burn fuel (diesel or gasoline, diesel is more) to provide power for its driving mechanism; The machine generates electricity to provide electric energy for the operation of the operating mechanism. What needs to be explained here is that some operating mechanisms rely on direct power...
