Power system with reverse blow-down capacity, vehicle body and aerial work platform

Abstract

The invention relates to the field of engineering machinery, in particular to a power system with reverse blow-down capacity, a vehicle body and an aerial work platform. The power system comprises a first box, an engine, a cooler and a fan assembly arranged between the engine and the cooler, wherein the first box is provided with vent holes; the engine, the cooler and the fan assembly are all arranged in the first box; the fan assembly comprises fan blades, a driving device for driving the fan blades to rotate and a control valve group for controlling the rotating direction of the driving device; a cooling connection pipe allowing circulation of a coolant is arranged between the engine and the cooler. Therefore, sundries or dust in the power system are cleaned automatically, the cleaning efficiency is higher, the labor intensity is lower, cleaning is more complete and the cleaning effect is better, the internal burning rate of the engine and the output power of the engine can be increased, pollutants in exhaust gas can be reduced, energy saving and environmental protection are realized, and a better cooling effect is realized.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of construction machinery, in particular to a construction work vehicle, and more particularly to a power system capable of reverse sewage discharge, a vehicle body and an aerial work platform. [0003] 【Background technique】 [0004] Aerial work platform is an advanced aerial work machine, which can greatly improve the work efficiency, safety and comfort of aerial construction personnel, and reduce labor intensity. It has been widely used in developed countries. The use of aerial work platforms in my country is also becoming more and more extensive, such as the initial general municipal street lamp maintenance, garden tree pruning, etc., and with the rapid development of my country's economy, engineering construction, industrial installation, equipment maintenance, plant maintenance, shipbuilding, The demand for aerial work platforms in electric power, municipal administration, airports, communications, garden...

AI Technical Summary

Problems solved by technology

[0005] Since the aerial work platform often works in an outdoor environment and workers often need to work on the operating platform, and the power system of the aerial work platform is generally located on the vehicle body (that is, under the operating platform) and the power system is generally not in a fully enclosed environment. (Reserve air inlet holes, etc.), therefore, it is inevitable that debris or dust will fall (deposit) to the components in the power system or in the gap between the components, and then, in order not to affect the power system Performance requires technology to clean up debris and dust. For this, the traditional method is to manually clean them up. This traditional method is not only low in work efficiency and labor-intensive, but also due to the complex structure of the power system, there are gaps between some components. The gap is small, which is not conducive to manual cleaning, which makes the cleaning incomplete and the effect is poor.
