Abstract
The utility model discloses a protective device for manual prevention and prevent automatically the diesel engine of a diesel locomotive overspeeding. The utility model is characterized in that an emergency button for deceleration and an automatic interlock switch can control three electro-controlled valves together; an application reservoir which is driven by the compressed air, installed on an acetabuliform windbreak plate which is in the inlet passage and can rotate by a rocking arm, can close the air inlet passage; all the high-pressure oil pump can be closed by connection between the piston of the application reservoir and the oil supply system, making the diesel engine having no air and no fuel to lower speed or stop.
Description
This technical field that the present invention belongs to: beeliner diesel engine specialty.
Existing diesel engine overspeed governor switch in practice, because active force is too little, when regulator control system resistance increase fault occurring, does not just have the effect of overspeed protection, emergency shutdown.
This invention be according to internal-combustion engine in when hypervelocity, need a large amount of air and fuel, cut off its necessary material conditions rapidly, prevent that the internal-combustion engine hypervelocity is out of control.
This device is to be grouped into by two cover circuit and relevant mechanical drive department:
One, prevent the manual circuit that exceeds the speed limit:
Master control switch-urgent reduction of speed control button-petrolift
↓
Forward and backward air flue and automatically controlled the cutting down of fuel feeding pull bar acting cylinder
Two, automatic shutdown protection circuit:
DLS anode power supply-automatic interlock switch-DLS coil
↓
Forward and backward air flue and automatically controlled the cutting down of fuel feeding pull bar acting cylinder
Below with reference to accompanying drawing invention is described in further detail.
Figure one, be air inlet shutoff device figure of the present invention.
Figure two, be air inlet shutoff device effect diagrammatic sketch of the present invention.
Figure three, be acceleration cut-out device figure of the present invention.
Figure four, be that acceleration of the present invention stops oil effect diagrammatic sketch.
Colluding shellfish with reference to figure one, two by the acting cylinder (4) of the compressed air-driven of automatically controlled cutting down (3) control promotes the dish-shaped choke plate (5) that rocking arm (7) is rotatably installed in the gas-entered passageway and does 90 ° of rotations.Close inlet air pathway.
Combine as a whole with combined regulator transmission arm (2) and fuel feeding rocking arm (1) with reference to figure three, four, one application reservoirs by compressed air-driven (6).When manual or automatic circuit was connected, effect was colluded shellfish and is stretched out with the air shutter structure and act on simultaneously, closes whole high pressure oil pumps.
Three, the manual action principle that prevents to exceed the speed limit:
When the unusual raising speed of diesel engine revolution, the driver and conductor presses urgent push buttondown, has closed the petrolift circuit, has opened forward and backward air passageways and the automatically controlled circuit that cuts down of fuel feeding pull bar application reservoir simultaneously.Front and back air passageways and fuel feeding pull bar acting cylinder collude shellfish and act on rapidly, rotate choke plate, close whole high pressure oil pumps and air inlet road.Make diesel engine not have reduction of speed or shutdown under the state of air, no fuel in moment.
Four, autostop action principle:
When diesel engine raising speed takes place when unusual suddenly, (operator is reflected too late) surpassed the nominal operation limit speed.The automatic stop arrangement effect; drive the automatic interlock switch; close the DLS circuit; opened the draining hole of combined regulator power piston bottom; make the fuel feeding pull bar collude under the promotion of shellfish in the reservoir effect; pull back rapidly, close each high pressure oil pump, simultaneously the automatic interlock switch on automatically controlled circuit and the automatically controlled circuit that cuts down of fuel feeding pull bar of cutting down of forward and backward air road.Dish-shaped choke plate and fuel feeding pull bar in the forward and backward air passageways collude at application reservoir under the promotion of shellfish, close forward and backward air passageways rapidly, make diesel engine moment under the state of no air, no fuel, rapid shutdown.
This invention is to adapt to China's national situation, and it is adapted at locomotive shop, each locomotive depot of system shop is installed additional, need not change former design.
This invention as horse back install additional on the high powered diesel locomotive in the whole nation, and will avoid the economic loss of units up to a million every year for country.Bring huge economical, societal benefits to safety of railway traffic.
This invention is compared with external same device: it have simple in structure, operation is easy for installation, safe and reliable, control is rapidly shut down electronic switch technology and special purpose test equipment that fast advantage does not have complexity. Accessory need not design specially, only with existing general hydraulic cylinder and automatically controlled the cutting down and common 3mm steel plate of locomotive.
Claims (4)
1, one by the manual circuit (-) that gives anti-hypervelocity; automatic shutdown protection circuit (=); common automatically controlled the cutting down of handling (3); controlling pneumatic acting cylinder (4); driving the choke plate (5) in the gas-entered passageway; do 90 ° of rotations and close the application reservoir (6) of oil pump, the diesel engine of composition prevents overspeed governor switch.
2, stipulate by claim 1: the automatic shutdown protection circuit (two) is characterized in that: automatic stop arrangement and automatic interlock switch constitute one and open and close circuit.
3, stipulate by claim 1: the acting cylinder (6) of closing oil pump is characterized in that: become one with oil supply system.
4, stipulate by claim 1: choke plate (5) feature of closing air is: be installed in the intake duct.
