Abstract
The utility model relates to a flameproof safety protection device used for an underground transport vehicle diesel engine, and the flameproof safety protection device belongs to the manufacture field of engineering transport equipment used for an underground coal mine, is characterized in that a braking protection valve is arranged on a brake valve block, and a control port of the braking protection valve is connected with a main gas path. A control port of an oil pressure valve is connected with an engine oil pressure port, and a temperature protection valve is arranged on a screw hole of a water inlet of a cooling water sleeve of an engine gas exhaust pipe. A temperature protection valve is arranged at the external surface of an engine cylinder, and a temperature protection valve is arranged on a connecting hole of an engine gas exhaust pipe outlet, and a control port of a water shortage protection valve is connected with a water-replenishing tank. The flameproof safety protection device is suitable for environment which has explosive gas mixtures, such as methane, etc., in the underground coal mine, and is used as random monitoring and safety protecting for safety and vehicle operation parameters. When the monitored parameters reach a limited index, a protection system alarms, a diesel engine system automatically closes, and the safety of environment and the diesel engine system is ensured.
Description
One, technical field
The utility model relates to a kind of down-hole transport vehicle use for diesel engine flame proof safety protection device, belongs to underground mine use engineering haulage device and makes the field.
Two, background technique
Haulage vehicle does not generally add safety system under the existing well, and timely monitor vehicle runnability is too high when engine coolant temperature, delivery temperature, surface temperature, can cause that motor damages, and forms hidden peril of explosion.The water supply tank drawdown is during to low water level, and vehicle continues operation can be made engine exhaust temperature rise to surpass set quota; When engine oil pressure is lower than minimum pressure, can cause motor to damage.
Three, summary of the invention
The purpose of this utility model is to provide a kind of diesel engine of monitor vehicle at random Operational Limits, cuts off diesel engine intake and oil supply system automatically, and Safety performance is strong, the down-hole transport vehicle use for diesel engine flame proof safety protection device that environmental pollution is little.
Technical solution:
The utility model braking Protective valve is installed on the brake valve piece, and braking Protective valve control mouth is connected with main gas circuit; Engine oil pressure valve control mouth is connected with the engine motor oil pressure port, and temperature protection valve on the engine exhaust pipe cooling jacket water intake tapped hole is equipped with the temperature protection valve on the engine cylinder outer surface, on the engine exhaust pipe outlet attachment hole temperature protection valve is housed; Excessive low water level protection valve control mouth is connected with water supply tank.
The utility model is applicable to the environment that explosive gas mixtures such as methane are arranged under the coal mine, monitoring at random and safety protection as safety and vehicle operating parameters, this device is owing to installed the braking Protective valve, and when braking Protective valve control mouth pressure was low pressure, brake valve cut off retardation pressure; The temperature protection valve is monitored engine coolant temperature, delivery temperature and surface temperature at any time; an engine oil pressure valve control mouthful incoming pressure is lower than setting value, excessive low water level protection valve in the water supply tank drawdown during to low water level; protective system is reported to the police; and close diesel engine system automatically, thereby guarantee the safety of environment and diesel engine system.
Guarantee the safe operation of diesel engine system.
Four, description of drawings
Fig. 1 is the utility model structural representation;
Five, embodiment
The utility model is made up of braking Protective valve 1, engine oil pressure valve 2, brake valve piece 5, main gas circuit 6, motor 7, water supply tank 8, and braking Protective valve 1 is installed on the brake valve piece 5, and braking Protective valve 1 control mouth is connected with main gas circuit 6; Engine oil pressure valve 2 control mouths are connected with motor 7 engine oil pressure mouths, temperature protection valve 3 on the motor 7 outlet pipe cooling jacket water intake tapped holes, on the motor 7 cylinder outer surfaces temperature protection valve 9 is housed, on the motor 7 exhaust outlet attachment holes temperature protection valve 10 is housed; Excessive low water level protection valve 4 control mouths are connected with water supply tank 8.
The utility model when main gas circuit 6 pressure for low pressure time braking Protective valve 1 close the cut-out retardation pressure; When braking Protective valve 1 on-state, allow parking braking to open, braking Protective valve 1 off state, vehicle is emergency braking both; Control mouthful incoming pressures when engine oil pressure valve 2 and be lower than 0.08MPa, motor 7 engine oil pressure deficiencies, engine oil pressure valve 2 cuts out gas circuit automatically and cuts off motor 7 air inlet oil-feed system closing diesel engines; Temperature protection valve 3, temperature protection valve 9, temperature protection valve 10 surpass 98 ℃, delivery temperature at motor 7 coolant water temperatures and surpass 70 ℃, surface temperature above 150 ℃; excessive low water level protection valve 4 is in the water supply tank drawdown during to low water level; automatically cut off gas circuit and close diesel engine 7 systems, guarantee the safety of environment and diesel engine system.
