A power cabin structure and an aerial work platform using the structure

Abstract

The invention discloses a power cabin structure. The power cabin structure comprises an air deflector (1-1), a radiator (2), an air filter (5), an engine (3) and a silencer (4) which are distributed in a power cabin in sequence. The air deflector (1-1) is communicated with outside air and arranged at an air inlet in the left side of a hood (1) and the air inlet face of the radiator (2). The air filter (5) is arranged on the air inlet face of the radiator (2) and communicated with an inner cavity of the air deflector (1-1). Meanwhile, the invention discloses an aerial work platform employing the power cabin structure. As the air deflector is arranged, it is avoided that hot air in the power cabin is sucked back by a fan, and heat dissipation performance is guaranteed; as an air inlet of the air filter is formed in the inner cavity of the air deflector, air sucked by the fan directly enters an air inlet pipe of the air filter in a positive pressure manner, and an air inlet system can obtain normal-temperature air easily; and as the silencer is arranged at a lower air port of the engine, it is avoided that heat generated by the silencer affects an engine body, and meanwhile hot air can be easily exhausted out of the cabin in time.

Description

technical field [0001] The invention relates to a power cabin for engineering machinery, in particular to a power cabin structure and an aerial work platform using the structure. Background technique [0002] Aerial work platforms are widely used in construction, shipbuilding, venue maintenance, cleaning and maintenance and other fields. Aerial work platforms are generally composed of a walking mechanism, a lifting mechanism (which can be a mast, a scissor mechanism or a combined arm frame), a body and a working platform. Among them, the lifting mechanism is fixed on the body, and the working platform is set above the lifting mechanism. [0003] For off-road aerial work platforms used outdoors, diesel engines are generally used to provide power; the engine is fixed on the aerial work platform frame or turntable, and is protected by a hood outside, confining the entire power system in the power cabin. Restricted by factors such as the movement performance of the whole machin...

AI Technical Summary

Problems solved by technology

[0009] 1) The cold air entering through I flows through the radiator 2 and is heated. Due to the pressure of the fan, part of the hot air flows back to the air inlet surface of the radiator 2, as figure 2 , as shown in path II, the recirculated hot air passes through the radiator 2 again, which cannot effectively cool the water tank of the radiator 2, resulting in a decrease in heat dissipation performance;

[0010] 2) The air filter 5 is arranged in the hot air circulation. When the air filter 5 needs to inhale the outside air, such as figure 2 As shown in path III, part of the hot air blown out by the fan is also sucked into exhaust path IV at the same time, resulting in an increase in the intake air temperature of the engine 3 and affecting the combustion efficiency. If the intake air temperature is too high, the power of the engine 3 will be reduced;

[0011] 3) The muffler 4 is arranged in a place where components are densely populated. Since the muffler 4 itself is a large heat source, it radiates heat to the surrounding components for a long time, resulting in a decrease in service life; in addition, the air temperature around the muffler 4 is high, which is not conducive to The engine machine 3 dissipates heat, and the heat radiation to the air filter 5 housing will also affect the intake air temperature of the air filter 5
