[0002] The advantages of diesel engines are high power and good economic performance. The working process of diesel engines has many similarities with gasoline engines. Each working cycle also goes through four strokes: intake, compression, power generation, and exhaust. However, since the fuel used in diesel engines is diesel, its viscosity is greater than that of gasoline and it is not easy to evaporate, but its auto-ignition temperature is lower than that of gasoline. Therefore, the formation and ignition method of the combustible mixture are different from those of gasoline engines. No matter what model of diesel engine is used for a long time, it needs to be disassembled from the equipment for maintenance.

[0003] However, when the existing lifting device lifts the diesel engine that needs to be repaired in the equipment, the diesel engine is lifted only by a hook and a wire rope loop, resulting in poor stability of the diesel engine when lifted, and it is easy to fall off, causing damage to the diesel engine. Secondly, when the existing lifting device transfers the diesel engine after the lifting is completed, the diesel engine is only lifted to a suspended state by the lifting device and then moved, which easily causes the diesel engine to shake during the movement and has poor stability.
