Description
Technical field
Down-hole sling cart hydraulic medium conversion equipment, belongs to Underground Mine carrying supplementary equipment technical field.
Background technique
Under coal mine, hanging device is one of main auxiliary equipment using in mining process.Along with the raising of production process automatic and mechanical level, in work surface, arrange, the installation, maintenance of equipment, dismounting, the transhipment of production site, uses hanging device more and more.Environmental suitability to hanging device, operational suitability, functional diversity also proposes increasing requirement.
Domestic conventional several hanging devices comprise special-purpose lifting lock, special-purpose lifting anchor pole, cantilever type Underwell used multi-function hoist, overhead trolley and other hanging device at present.The shortcoming of special-purpose lifting lock is to carry out the lifting of lighter equipment, and can not carry out transverse shifting.Special-purpose lifting anchor pole shortcoming is the fixing cumbersome of lifting steel I-beam, and the reliability of lifting anchor pole is not high, and hoisting weight is limited, and the explosion-proof reliability of explosion-proof electric block is not high.The shortcoming of cantilever type Underwell used multi-function hoist is must be fixed on underground orbit, and lifting weight is little, and spatial constraints factor is larger.Because overhead trolley is lifting and shifter to be hung in orbit and track is fixed on the hanging device on top board, its shortcoming is that back and supporting are required to height, need to have the hanging bearing of reliable suspended single-track.In addition, the weight that overhead trolley is sling can only move along the trend of track, the slinging and fall that can not to depart from track below too far away of weight.This has just limited its application area.
The power section of above-mentioned hanging device adopts electro-hydraulic pumping system conventionally, yet thereby when the electrical installation of down-hole, easily producing the ignite inflammable gass such as gas of down-hole of electrical spark blasts, cause the generation of colliery serious accident.While therefore using electric automatization equipment under coal mine, necessarily require to make it have reliable explosion-proof performance, or avoid using too many electrical equipment as far as possible.Meanwhile, down-hole malaria environment has limited the use of electric automatization equipment again, and airborne aqueous vapor is infiltrated in electrical equipment, has not only affected the working life of electrical equipment, but also has brought certain potential safety hazard.As can be seen here, under planned well, during Lift-on/Lift-off System, must consider above-mentioned restraining factors, avoid using electric automatization equipment as far as possible.
In addition, the oil hydraulic motor working medium of hydraulic pump system mostly is hydraulic oil, not only brings the raising of user cost, and the transportation of the pipeline of hydraulic oil had both taken up room, and also Security is low.Meanwhile, at mining face under mine, but there is a large amount of emulsified liquids to fail to make full use of.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly can utilize existing mining face under mine emulsified liquid to realize the emulsified liquid-oil pressure conversion equipment under high pressure conditions, and the hoisting machine that is converted to of realizing driving medium with this provides power.
For solving the problems of the technologies described above, the technical solution adopted in the present invention: down-hole sling cart hydraulic medium conversion equipment, comprise the first oil hydraulic cylinder, the second oil hydraulic cylinder, three-position four-way valve, emulsified liquid fuel tank, hydraulic oil container and oil hydraulic pump, the piston rod of the piston rod of described the first oil hydraulic cylinder and the second oil hydraulic cylinder is integral type piston rod, the first oil hydraulic cylinder is communicated with actuator port A mouth, the B mouth of three-position four-way valve, the P mouth of three-position four-way valve is communicated with oil hydraulic pump, T mouth communicates with emulsified liquid fuel tank, and the second oil hydraulic cylinder communicates with hydraulic oil container.
At described oil hydraulic pump two ends, be also parallel with relief valve.
Between hydraulic oil container and clutch end telescopic cylinder, be also provided with stop valve.
Compared to the prior art the present invention has following beneficial effect: the present invention uses the emulsified liquid power source of working surface, has reduced the demand to hydraulic oil, and need not any power supply.The cancellation of power supply, both without heavy explosion-proof electric apparatus case, again without anti-explosion motor and pumping plant, has reduced the weight of hoisting machine, has reduced job costs and space hold, has improved the Security of using.
Working state of the present invention as shown in Figure 1 and Figure 2, when emulsified liquid is from the input of hydraulic medium conversion equipment left end liquid entering hole, export from hydraulic medium conversion equipment upper right oil outlet by high pressure liquid force feed; When emulsified liquid enters from middle liquid entering hole, hydraulic medium conversion equipment right-hand member is prepared the circulation of oil extraction next time from fuel tank oil suction, thereby input high-pressure emulsion in one end while realizing work, the hydraulic oil of the other end output high pressure, high pressure liquid force feed drives each hydraulic pressure execution device.Between hydraulic oil and emulsified liquid, there is in addition a set of isolation mounting, prevent that two liquid phases from ganging up mutually;
During specific works of the present invention, the work of three-position four-way valve right-hand member act bit, hydraulic pump works, one time power source high-pressure emulsion constantly enters right half cavity of the first oil hydraulic cylinder by emulsified liquid fuel tank through oil hydraulic pump, three-position four-way valve, promote piston in the first oil hydraulic cylinder to left movement, the emulsified liquid pressurized in the first oil hydraulic cylinder left half cavity body turns back to emulsified liquid fuel tank through three-position four-way valve.The piston of the piston of the first oil hydraulic cylinder and the second oil hydraulic cylinder is rigidly connected, at this moment the piston in the second oil hydraulic cylinder is also to left movement, make like this right-hand member of the second oil hydraulic cylinder constantly from hydraulic oil container oil suction, and hydraulic oil in the second oil hydraulic cylinder left end chamber constantly pours in telescopic cylinder, telescopic cylinder stretches out; When telescopic cylinder reaches limit position, stroke no longer changes, and emulsified liquid constantly enters in the first oil hydraulic cylinder, and pressure constantly increases, at this moment relief valve work, and emulsified liquid is got back to emulsified liquid fuel tank through relief valve;
When the work of three-position four-way valve left end act bit, hydraulic pump works, one time power source high-pressure emulsion constantly enters the first oil hydraulic cylinder left half cavity body by emulsified liquid fuel tank through oil hydraulic pump, three-position four-way valve, the piston promoting in the first oil hydraulic cylinder moves right, and the emulsified liquid in right half cavity of the first oil hydraulic cylinder is forced to get back to emulsified liquid fuel tank through three-position four-way valve.The piston of the piston of the first oil hydraulic cylinder and the second oil hydraulic cylinder is for being rigidly connected, at this moment the piston in the second oil hydraulic cylinder also moves right, make like this right-hand member hydraulic oil of the second oil hydraulic cylinder get back in hydraulic oil container, and hydraulic oil in the second oil hydraulic cylinder left end chamber is constantly got back in the second oil hydraulic cylinder 2 from telescopic cylinder, telescopic cylinder is retracted.
