3, the rodless cavity hydraulic fluid port of hydraulic fluid port P and drg oil cylinder 11 links, hydraulic fluid port T shutoff.
Principle of work of the present invention is:
The starting of system:
Actuating motor, 2 runnings of enclosed pump, enclosed pump 2 is built-in with main pump and slippage pump, the main pump of enclosed pump 2 since tensioning explosion-proof 3-position 4-way solenoid directional control valve 8 all not, so main pump does not have hydraulic oil output, the slippage pump of enclosed pump 2 is under low pressure worked (2.5MPa) at this moment, the power of motor of its consumption very little (being about 2% motor rated power), and we can think that motor belongs to No Load Start.
The operation of system and speed control:
Under the condition of motor operation, get when electric when driving explosion-proof 3-position 4-way solenoid directional control valve 8 left side electromagnet, the pressure oil (2.5Mpa) of slippage pump output servovalve in left side position → promotion enclosed pump 2 pumps of damping orifice plate 7 → explosion-proof 3-position 4-way solenoid directional control valve 8 of driving moves to position, a left side, this moment under the pressure oil effect of the built-in slippage pump of enclosed pump 2 → swash plate deflection → output oil stream → HM Hydraulic Motor 6 of the main pump of enclosed pump 2 turns round, thereby drive the rotation of cableway drive wheel, the haulage cable operation.
When regulating explosion-proof proportional pressure control valve 9, can change the later hydraulic fluid pressure of damping orifice plate 7, thereby influence the aperture of servovalve in enclosed pump 2 pumps, cause the pressure reduction on it to change, because entering the pressure of enclosed pump 2 main pump internal variables control oil cylinder changes, this pressure is during with the in-oil cylinder action of the spring force balance of control, the swash plate positions of main pump is fixed, thereby make the output oil stream of main pump stable, guaranteed the stable of system running speed, change the electric current that drives explosion-proof 3-position 4-way solenoid directional control valve 8, the speed of system changes thereupon.
When changing by 8 right electromagnet energisings of the explosion-proof 3-position 4-way solenoid directional control valve of driving, system is with inverted running, and the adjusting of its speed is still realized by the electric current of regulating explosion-proof proportional pressure control valve 9.
(speed accelerates to the setting running velocity from zero during startup for the startup of cableway haulage cable and the acceleration and deceleration characteristic when stopping, decelerate to the zero time from running velocity when stopping), by the output characteristic decision that is connected the VRM Voltage Regulator Module on the explosion-proof proportional pressure control valve 9.
Safety precautions
In order to prevent enclosed pump 2 because of oil starvation damages, on the pressure oil circuit of enclosed pump 2 slippage pumps, oil compensation pressure signal transducer 21 has been installed, when oil compensation pressure was lower than 0.8Mpa, pressure sensor imported this into computing machine, and shut down at the control motor.
The principle of work of hydraulic pressure tension system:
When explosion-proof 3-position 4-way solenoid directional control valve 13 left side electromagnet of tensioning get, then the pressure oil stream of tensioning oil pump 3 output is through the rod chamber of left side position → one-level flow regulating valve 14a → hydraulic control one-way valve 15 → tensioning hydro-cylinder 17a, the 17b of the explosion-proof 3-position 4-way solenoid directional control valve 13 of the tensioning → piston rod of tensioning hydro- cylinder 17a, 17b is taken in, this moment tensioning hydro- cylinder 17a, 17b the oil return process two-step throttle valve 14b of rodless cavity and the A mouth of the explosion-proof 3-position 4-way solenoid directional control valve 13 of tensioning on oil returning branch pipe T
5Oil sump tank 4.Tensile force detects by pressure signal sensor 22 in the tensioning process, and imports computing machine into, and when tensile force surpassed the setting of by pass valve 16, by pass valve 16 overflows made tensile force constant in setting value.
When the right position of the explosion-proof 3-position 4-way solenoid directional control valve 13 of a tensioning electromagnet gets when electric, the rodless cavity of right position → two-step throttle valve 14b → tensioning hydro-cylinder 17a, the 17b of the explosion-proof 3-position 4-way solenoid directional control valve 13 of the tensioning oil pump 3 pressure oil output process → tensionings → piston rod of tensioning hydro- cylinder 17a, 17b is stretched out, thereby reduce the tensile force of haulage cable, the A mouth of the oil return of tensioning hydro- cylinder 17a, 17b rod chamber process hydraulic control one-way valve 15, one-level flow regulating valve 14a and the explosion-proof 3-position 4-way solenoid directional control valve 13 of tensioning is through oil returning branch pipe T at this moment
5 Oil sump tank 4.
Can set the operation pressure of tensioning oil pump 3 by regulating by pass valve 12; The effect of one-level flow regulating valve 14a, secondary 14b is to make that tensioning hydro- cylinder 17a, 17b can slowly move reposefully in the tensioning process; Hydraulic control one-way valve 15 makes tensioning hydro- cylinder 17a, 17b keep constant operation pressure.
The principle of work of hydraulic brake system:
Explosion-proof two-position four-way solenoid valve 10 is used for modulated pressure drg oil cylinder 11, and it is under the state of not energising, and the hydraulic oil that can make hydraulic brake oil cylinder 11 is directly through oil returning branch pipe T
3Enter fuel tank 4, cableway is a braking mode.When ropeway operation, the energising of the electromagnet of explosion-proof two-position four-way solenoid valve 10, hydraulic brake oil cylinder 11 piston rods are opened damper brake under the effect of pressure oil, and cableway starts operation.
