Embodiment
As shown in Figure 1, the all-hydraulic high difference compensating device of a kind of mine well head, being included as the all-hydraulic high difference compensating device of mine well head provides the oil pump 5 of power, the electromagnetic relief valve 3 in parallel with oil pump 5, connect with oil pump 5 after solenoid directional control valve A1 and the solenoid directional control valve B2 parallel connection, solenoid directional control valve A1 is communicated with control oil circuit a, control oil circuit a comprises oil hydraulic motor 11 and safety valve 9 in parallel, oil hydraulic motor 11 and safety valve 9 one ends are communicated with series flow control valve 7, the other end is communicated with solenoid directional control valve A1, solenoid directional control valve B2 is communicated with control oil circuit b, control oil circuit b comprises oil hydraulic motor 12 and safety valve 10 in parallel, and oil hydraulic motor 12 and safety valve 10 1 ends are communicated with series flow control valve 8, and the other end is communicated with solenoid directional control valve B2, solenoid directional control valve A1, between B2 and the oil pump 5 pipeline is set and directly is communicated with fuel tank 14, fuel tank 14 also is communicated with oil pump 5 and electromagnetic relief valve 3.
For the better whole device of control arranges pressure gauge 6 between the oil pump 5 of above-described embodiment and solenoid directional control valve A1, B2; Be provided with oil purifier 13 between oil pump 5 and the fuel tank 14; Be provided with heater 4 at the all-hydraulic high difference compensating device of mine well head and be communicated with fuel tank 14; Solenoid directional control valve A1, B2, electromagnetic relief valve 3, series flow control valve 7,8, safety valve 9,10 are connected control cabinet and realize telecontrol with oil pump 5; Further the control oil circuit of above-described embodiment can arrange a plurality ofly, sets according to the mine needs of production.
As shown in Figure 2: after mine car 17 entered saddle 15, well head all-hydraulic high difference compensating device power source oil pump in mine was opened, and the hydraulic oil that oil pump is discharged returns fuel tank through electromagnetic relief valve, and performance element oil hydraulic motor 16 is output torque not.When electromagnetic relief valve and solenoid directional control valve energising, the pressure hydraulic oil that oil pump is discharged enters oil hydraulic motor 16 left chambeies through the one-way valve of solenoid directional control valve, series flow control valve, under the effect of pressure oil, promote oil hydraulic motor 16 rotations, the oil return of oil hydraulic motor 16 is returned fuel tank through solenoid directional control valve, make it output torque, by saddle 15 mine car is promoted to certain altitude.After mine car 17 leaves saddle, electromagnetic relief valve energising and solenoid directional control valve dead electricity, under the effect of saddle 15 gravity, oil hydraulic motor 16 counter-rotatings, the hydraulic oil-returning of oil hydraulic motor 16 is realized half-closed loop through the right working position of solenoid directional control valve.Oil hydraulic motor 16 oil circuits utilize solenoid directional control valve to the oil hydraulic motor oil circuit in the effect of negative pressure from the reverse repairing of fuel tank, thereby realized the steady decline of saddle.The aperture of the restriction by adjusting series flow control valve can reach the control to the saddle rate of descent.The effect of safety valve be when saddle is subjected to external impacts to the low voltage terminal emptying, realize oil hydraulic motor is protected.
