Crane and engine system thereof

Abstract

The invention discloses an engine system of a crane. The engine system comprises an natural gas engine (11) and gas storage tanks (14), wherein the natural gas engine (11) is arranged on a walking platform plate (30) between a crane cab (31) and a turntable (32), the gas storage tanks (14) contain high-pressure gasified natural gas, shut-off valves which are used for being connected or disconnected with outside inflating pipes are arranged at gas inlets of the gas storage tanks (14), gas outlets of the gas storage tanks (14) are communicated with a gas inlet of the natural gas engine (11) through a pipeline, and a pressure reducing assembly (16) and a valve (190) which is used for connecting or disconnecting the pipeline are further arranged on the pipeline. According to the engine system of the crane, disclosed by the invention, the gasified natural gas is taken as a fuel, so as to meet the working needs of the crane, and the price of the fuel is relatively cheap, so that the use cost of the crane can be reduced. On the other hand, the engine system of the crane is beneficial to environmental protection; in addition, the explosion resistance of natural gas is relatively good, so that noise generated during work is relatively low. The invention further discloses the crane with the engine system.

Description

technical field [0001] The invention relates to the technical field of engineering machinery power control, in particular to an engine system. The invention also relates to a crane having an engine system as described above. Background technique [0002] At present, the crane power system is basically matched with a diesel engine system. The diesel engine system includes a diesel engine and an oil supply system connected to the diesel engine. The oil supply system includes two parts: an oil inlet part and an oil return part. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical diesel engine system in the prior art. [0004] The oil inlet part mainly includes parts such as diesel oil tank 6, coarse filter 5, engine oil inlet pipe 3, engine fuel supply pump 2, diesel fine filter 1; The oil return part mainly includes oil return pipe 4; Under the action of the fuel supply pump 2, it is pumped out from the oil outlet of the diesel ta...

Problems solved by technology

[0005] As we all know, large-scale machinery such as cranes consume a lot of diesel oil, but with the continuous exploitation of oil energy, the amount of oil is decreasing year by year, and the price of diesel oil is also increasing, resulting in higher and higher operating costs for cranes.
