Abstract
The utility model relates to a mining explosion-proof diesel engine stop device has solved the mode that current mining explosion-proof diesel engine compressed air promoted piston cylinder and has controlled the diesel engine and admit air and the compressed air that the fuel pump oil spout exists reveals easily, the slow problem of piston response. The technical scheme includes that the fuel pump comprises a fuel pump in a diesel engine and a valve body connected with an air inlet elbow of the diesel engine, and the fuel pump is characterized in that a fuel cut-off plug in the fuel pump is connected with a fuel cut-off electromagnetic valve through a connecting rod, and a valve block in the valve body is connected with an air cut-off electromagnetic valve. The utility model has the advantages of being simple in structure and convenient in operation, response speed is fast, fail safe nature is high.
Description
Technical field
The utility model relates to a kind of automobile-used parts, a kind of specifically anti-explosion diesel engine for mine arresting gear.
Background technique
The mode that present anti-explosion diesel engine for mine arresting gear generally adopts pressurized air to promote piston-cylinder is controlled diesel engine intake and fuel pump oil spout, and not enough below it exists: 1, pressurized air is revealed easily, causes the valve block of dying to close; 2, it is slow that pressurized air promotes the piston response, under emergency, shuts down slowly; Just because of above reason, make to shut down when anti-explosion diesel engine for mine uses under mine to become very unreliable, be easy to generate personal injuries such as machinery.
Summary of the invention
The purpose of the utility model is in order to solve the problems of the technologies described above, and a kind of simple in structure, speed of response is fast, safety reliability is high anti-explosion diesel engine for mine arresting gear is provided.
Technological scheme comprises the fuel pump in the diesel engine, and connects the valve body on the diesel engine intake bend pipe, and the oil-break stick harness in the said fuel pump is connected with Fuel Cut Solenoid Valve through connecting rod, and the valve block in the said valve body is connected with the solenoid valve of dying.
The said Fuel Cut Solenoid Valve and the solenoid valve of dying connect relay, and relay connects battery pack, is in series with halt switch on said relay and the battery pack link circuit.
Because said mine anti-explosion diesel engine railless free-wheeled vehicle is used for operation under the ore deposit, so each parts of the utility model all need be abideed by in the industry standard and carried out conventional flame proof and handle.
Beneficial effect:
Simple in structure, easy to operate; Adopt the Fuel Cut Solenoid Valve of electronic control and the solenoid valve of dying is controlled the valve of corresponding valve body and the oil-break stick harness of fuel pump respectively, thoroughly solved the response that pneumatic control brings slow, shut down slowly, the problem of complex structure, safety reliability difference.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model electrical schematic diagram.
Wherein, die solenoid valve, 14-inlet pipe connection, 15-air-strainer of 1-diesel engine, 2-fuel pump, 3-oil-break plunger, 4-connecting rod, 5-Fuel Cut Solenoid Valve, 6-elastic cable paper, 7-battery pack, 8-relay, 9-stop botton, 10-intake elbow, 11-valve body, 12-valve block, 13-.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained:
With reference to Fig. 1, Fig. 2; Diesel engine 1 be provided with fuel pump 2; Oil-break plungers 3 in the fuel pump 2 are connected with Fuel Cut Solenoid Valve 5 through connecting rod 4, and said diesel engine 1 upper-end surface is connected with intake elbow 10, are provided with valve body 11 between intake elbow 10 and the inlet pipe connection that is connected air-strainer 15 14; Valve block 12 is equipped with in valve body 11 inside, and said valve block 12 is connected with the solenoid valve 13 of dying; Fuel Cut Solenoid Valve 5 and the solenoid valve 13 of dying are respectively through being connected of elastic cable paper 6 and relay 8, and relay 8 is connected with battery pack 7, also are in series with stop botton mutually 9 on the link circuit of relay 8 and battery pack 7.When diesel engine need be shut down; Only need press stop botton 9, then cut off battery pack 7 and supplied power with Fuel Cut Solenoid Valve 5 to the solenoid valve 13 of dying through relay 8, two solenoid valves automatically reset; The solenoid valve 13 of dying drives valve block 12 valve body 11 and cuts off the air feed approach; Fuel Cut Solenoid Valve 5 drives oil-break stick harness 3 and closes fuel pump 2 fuel feeding approach, thereby corresponding air feed and the fuel feeding of having cut to disconnected diesel engine 1 reaches the shutdown purpose.
Claims (2)
1. anti-explosion diesel engine for mine arresting gear; Comprise the fuel pump in the diesel engine, and connect the valve body on the diesel engine intake bend pipe, it is characterized in that; Oil-break stick harness in the said fuel pump is connected with Fuel Cut Solenoid Valve through connecting rod, and the valve block in the said valve body is connected with the solenoid valve of dying.
2. anti-explosion diesel engine for mine arresting gear as claimed in claim 1 is characterized in that, the said Fuel Cut Solenoid Valve and the solenoid valve of dying connect relay, and relay connects battery pack, is in series with halt switch on said relay and the battery pack link circuit.
