Abstract
The utility model relates to a safe starting control device for an underground transport truck and belongs to the field of engineering transportation equipment used for an underground coil mine. The safe starting control device is characterized in that compressed air is adopted as the starting power; an air storage tank is connected with a ball valve, a motor control valve and an air motor; the air motor is mounted on an engine; the control valve comprises a starting/boosting button, three control valves and an engine oil pressure protection valve; a control port of the engine oil pressure protection valve is connected with the engine; and the starting button is connected with the control valve and the air motor. When a starting air path of the engine is communicated, the engine oil pressure protection valve for controlling engine oil pressure is communicated with a working air path of the engine, the starting air path simultaneously and automatically cuts off and the connection of an air inlet and oil supply system of a diesel engine is kept, so that the engine is in a normal working state. The utility model is applicable to the environment that methane and other explosive gas mixtures exist in the underground coil mine and has the function of protecting the engine oil pressure; and when the oil pressure is lower than a limited indicator value, an engine system is automatically closed, so that the engine system safely works.
Description
One, technical field
