Abstract

The invention discloses a starting system of an aboard self-contained engine of a crane in a low temperature environment. The starting system comprises an aboard hydraulic system provided with an aboard hydraulic oil pump, a hydraumatic auxiliary start-up system with a hydraumatic auxiliary starting motor, a pressure oil source for providing power to the hydraumatic start-up system, and a control valve used for controlling the hydraumatic auxiliary starting motor. The invention discloses a starting method of the aboard self-contained engine of the crane in the low temperature environment. The starting system and method provided by the invention have the beneficial effects that even in a place which lacks of resources in the low environmental temperature, the aboard self-contained engine can be started up without spending a good deal of manpower and material resources and time; only one person can finish starting the aboard self-contained engine in the low temperature environment without consuming external resources; and only the crane can rapidly, smoothly, securely finish starting of the aboard engine.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a system and a method for facilitating the start-up of an independent engine on a crane in a low-temperature environment. Background technique [0002] At present, on large-tonnage cranes, both the boarding and dismounting have independent engine systems, especially in the boarding engine system. Due to space constraints, the engine is directly connected to the hydraulic oil pump. Therefore, in the process of starting the engine, the engine must not only overcome the resistance torque of the engine itself, but also overcome the initial resistance torque of the hydraulic oil pump system. Especially in the case of low external ambient temperature in winter, due to the high viscosity of hydraulic oil and lubricating oil, the resistance torque of the engine itself and the resistance torque of the hydraulic oil pump system increase. As the ambient temperature continues to decrea...
