An automatic shutdown and brake system of a mining explosion-proof trackless rubber-tyred vehicle is characterized in that an intrinsic safety type travel switch is mounted at a main driving door and connected with a control power supply of a mining intrinsic safety type control box, the control box is respectively connected with an explosion-proof electromagnetic valve and a main engine of a mining explosion-proof and intrinsic safety type diesel engine fuel injection electric control device, an inlet of the explosion-proof electromagnetic valve is connected with brake oil, and an outlet of the explosion-proof electromagnetic valve is connected with an outlet of the mining explosion-proof trackless rubber-tyred vehicle. The output port is connected with an axle brake, and the main engine of the mining flameproof and intrinsic safety type diesel engine fuel injection electric control device is connected with a diesel engine. A travel switch and an electromagnetic hydraulic valve are additionally arranged in an original vehicle control system, when a vehicle door is opened, the travel switch works and transmits an electric control signal to cut off a working signal of an engine and a power supply of the electromagnetic hydraulic valve, so that the engine is stopped, meanwhile, due to the fact that the electromagnetic hydraulic valve is powered off, oil supply of an axle parking brake is cut off, and an axle is in an emergency braking state.

    一种矿用防爆无轨胶轮车自动关机刹车系统,本安型行程开关安装于主驾车门处,与矿用本安型控制箱控制电源相连接,控制箱分别与防爆电磁阀、矿用隔爆兼本安型柴油机燃油喷射电控装置主机相连接,防爆电磁阀入口接制动油液,输出口接车桥制动器,矿用隔爆兼本安型柴油机燃油喷射电控装置主机与柴油机相连接。在原车辆控制系统中增加行程开关和电磁液压阀,当车门打开时,行程开关工作,传递电控信号将切断发动机工作信号与电磁液压阀供电电源,使发动机停机,同时由于电磁液压阀断电,切断车桥驻车制动器油液供应,车桥处于紧急制动状态。
