Description
Technical Field
The utility model belongs to the technical field of electric engineering machinery, in particular to self-propelled crawler-type portable power source power supply unit.
Background
Low carbonization and high cost have been difficult choices that plague urban development. The total amount of construction machinery is not large, but the amount of emissions per unit is high. For example, the exhaust emission of 1 traditional fuel excavator is equivalent to the emission of more than 50 household automobiles, the necessity of emission reduction is obvious, and the engineering or enterprise operator is difficult to pay higher cost for emission reduction.
As is well known, in the conventional electric vehicles such as electric automobiles and electric buses, an engine, an oil tank and the like are detached and replaced by a battery and a motor. How to improve the energy density of the battery and prolong the endurance mileage is the biggest subject. Therefore, domestic and foreign companies such as Tesla and Biddi are all able to run electric vehicles farther than piecing together.
The electric quantity used by the electric excavator every day is at least more than 5 times that of the electric automobile, and the electric excavator cannot run to find the charging pile for charging like the electric automobile. If the electric excavator needs to continue the electric scheme of the automobile, the electric excavator must fall into the puddle. Recently, many large-scale construction machinery manufacturers have announced the development of battery-powered electric excavators, but none of them can actually be used at ordinary construction sites. The fundamental reason for this is that they do not notice that the total amount of batteries required by an electric excavator has reached a level of qualitative or quantitative change.
From the perspective of sharing economy, the complex and expensive power supply part is changed into a universal and sharable independent unit product, and the economic benefit is much higher. For example, the actual service time of one excavator is generally not more than 25%, and 75% of the time is in a drowsy state, if people can share the power supply vehicle with other excavators or other electric machines when the excavator is in the drowsy state, the profitability of the power supply vehicle can be improved by one to three times. The greatest benefit of the electric operation of the mobile machinery is the oil-electricity price difference, the cost of electricity for one machine is only 1/3 of oil if the machine does the same work, and the more the oil consumption of the machine is, the higher the benefit obtained by changing the machine into the electric operation is.
Connect with a cable between excavator and supply vehicle and carry out the operation, certainly not more convenient than original diesel excavator, let electric excavator go to compare with diesel excavator and be good or bad, really difficult. However, while not as good as diesel in terms of energy density and portability, electric propulsion can be much easier to control accurately than engines, and it is shorter and shorter than diesel.
The essential way for the future development is to give up the ever brilliant value of the traditional fuel engineering machinery, introduce the electric intelligent technology and enable unprofessional people to simply operate the electric engineering machinery. The electric energy can enable a control system of the excavator to become more accurate and easier, the convenient movement of the self-walking crawler-type power supply vehicle can not only make up the defect of inconvenient carrying of electric power in large quantity, but also greatly improve the adaptation range of severe working condition conditions.
China in 2019 will begin to implement the national IV emission standards for off-road machines. For diesel engines used in construction machinery, nation iv is different from nation iii essentially. Country iii is affected mainly by the engine manufacturer, while country iv will affect the entire industry chain. The manufacturing costs of the engine manufacturer, the host developer, the service costs of the agent and the use costs of the end user will increase at the same time. The improvement of the emission standard is actually the biggest support for electric selection, and will force many manufacturers of engineering machinery to make a difficult choice: continuing to use the engine, followed by the engine suffering once every three years of disaster relief (emission standards increase once every 3-4 years); and (4) electrically transforming, namely abandoning the past glory and creating a new electric product again.
At present, the traditional hydraulic excavator adopting an internal combustion engine as primary power has the defects of dependence on petroleum resources, noise and serious environmental pollution caused by emission. The electromotion is gradually becoming an important development direction of the excavator. In addition, in certain special regions in China, the electric power resources are very rich, the electricity price is very low, the electric excavator is convenient to use, and the energy consumption cost is greatly reduced.
To date, no mature industrialized products exist, no matter the electric excavator itself or the power supply system thereof, and some key technical problems still need to be solved in the technology. At the present stage, in the power supply concept of the electric excavator, a self-walking crawler-type power supply vehicle based on the idea of rapid replacement and adaptation to severe working conditions is one of feasible schemes for supplying power to the electric excavator, and the basic idea is to provide a mobile power supply unit product capable of being operated remotely, walking independently and climbing for the electric excavator.
