The invention relates to the technical field of anti-explosion diesel engine vehicles, in particular to a cold starting device of an anti-explosion diesel engine vehicle. The problem that the anti-explosion diesel engine vehicle has difficulty in starting in winter is solved. The cold starting device comprises a gas storage tank, an anti-explosion diesel engine, an auxiliary pump and a traveling closed type pump which are installed on the vehicle, and further comprises a cold starting operating valve and a cold starting device body. The cold starting device body comprises a main pump cold starting unloading valve and an auxiliary pump unloading valve, high-pressure gas in the gas storage tank acts on the auxiliary pump unloading valve through the cold starting operating valve so that the auxiliary pump unloading valve can conduct steering and unloading, the additional load, except the starting torque, needed by operation of the diesel engine vehicle is cut off, and starting of the vehicle is achieved through the cold starting device. According to the cold starting device, the one-time starting success rate of the diesel engine in the low-temperature environment is increased, the time that the vehicle cannot be started and has to be rescued through other vehicles is shortened, and the working efficiency of the vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of explosion-proof diesel engine vehicles, in particular to a cold start device for explosion-proof diesel engine vehicles. Background technique [0002] Some coal mine vehicles use explosion-proof diesel engines as the power source and air motors as the starting system, and the users are mainly distributed in the northern regions of my country. Under the working conditions of low ambient temperature in winter, it will be difficult for diesel engines to start. The steering system, braking system, oil cylinder and other operating mechanisms of the vehicle are driven by hydraulic pressure, and the walking system of some vehicles is also driven by hydraulic pressure. Their power depends on the hydraulic pump driven by the diesel engine, which increases the load when the explosion-proof diesel engine starts. [0003] At the same time, due to the special explosion-proof requirements of the underground, the vehicle...
