The present invention has following beneficial effect, and (1) hydraulic driving can realize cableway stepless speed regulation and clockwise and anticlockwise campaign, can be in very low speed (can set arbitrarily) clockwise and anticlockwise down, so that the inspection wire rope; (2) can realize the starting under no load of motor, thereby improve the working life of motor and electric elements; (3) the acceleration, deceleration characteristic (can set the time of quickening and stopping and slowing down that starts) that can set starting arbitrarily and stop, thus the travelling comfort of taking improved; (4) be suitable for abominable working environment (many dirt, humidity and require explosion-proof) condition, its hydraulic oil flow circulates between oil hydraulic pump and motor, and working connection does not directly contact with air, thereby can not produce the suction sky and be not easy contaminated system; (5) owing to need not adopt explosion-proof device speed governing (like the flame proof frequency variator),, do not lose quick-fried hazards because do not exist so in the fire damp environment, use the hydraulic system speed governing safer.
Description of drawings
Fig. 1 is the structure principle chart of the mining cableway of the present invention with single action power hydraulic station.
Embodiment
As shown in Figure 1; A kind of mining cableway comprises motor 4, enclosed pump 14, hydraulic driving system with single action power hydraulic station, on motor 4, connects enclosed pump 14; Filter 23 is arranged on the oil outlet tube of fuel tank 1; On the return tube of fuel tank 1, connect radiator 5, the annexation of described hydraulic driving system is: the oil outlet tube of the filler opening S connected tank 1 of enclosed pump 14, and enclosed pump 14 built-in slippage pump oil outlet X3 and orifice valve piece 24 link; On slippage pump oil outlet X3, be connected to pump and join filter 2; The P hydraulic fluid port of the other end of orifice valve piece 24 and explosion-proof proportional pressure-reducing valve 21 links, and the other end A hydraulic fluid port of explosion-proof proportional pressure-reducing valve 21 connects with the P hydraulic fluid port of explosion-proof 3-position 4-way solenoid directional control valve 19, the T hydraulic fluid port of explosion-proof proportional pressure-reducing valve 21 drain tap T and explosion-proof 3-position 4-way solenoid directional control valve 19 and the oil returning branch pipe T of fuel tank 1
3Connect; The A of explosion-proof 3-position 4-way solenoid directional control valve 19, B hydraulic fluid port link the oil returning branch pipe T of the drain tap X4 connected tank 1 of enclosed pump 14 with Variable Control oil cylinder interface X1, the X2 of enclosed pump 14 respectively
1, enclosed pump 14 main oil pipe interface A, B meet A, the B interface of oil hydraulic motor 17, the oil returning branch pipe T of the drain tap connected tank 1 of oil hydraulic motor 17 respectively
2On the pipeline of the A interface of enclosed pump 14 main oil pipe interface A and oil hydraulic motor 17, be connected to driving pressure sensor 12.2; On the pipeline that enclosed pump 14 built-in slippage pump oil outlet X3 and orifice valve piece 24 link, be connected to oil compensation pressure signal emitter 22.
Working principle of the present invention is:
The starting of system:
Actuating motor; Then oil pump running; The main pump of enclosed pump 14 since drive explosion-proof 3-position 4-way solenoid directional control valve 19 all not electric, export so main pump has hydraulic oil, at this moment the slippage pump of enclosed pump 14 under low pressure work (2.4MPa); The power of motor of its consumption very little (being about 2% motor rated power), we can think that motor belongs to No Load Start.
The operation of system and speed controlling:
Under the condition of motor operation; Get when electric when driving explosion-proof 3-position 4-way solenoid directional control valve 19 left side electromagnet; The pressure oil (2.4Mpa) of slippage pump output servovalve in left side position → promotion enclosed pump 14 pumps of damping orifice plate 24 → explosion-proof 3-position 4-way solenoid directional control valve 19 of driving moves to position, a left side; This moment under the pressure oil effect of enclosed pump 14 built-in slippage pumps → swash plate deflection → output oil stream → oil hydraulic motor 17 of the main pump of enclosed pump 14 turns round; Thereby drive the rotation of cableway driving wheel, the haulage cable operation.
When regulating explosion-proof proportional pressure-reducing valve 21, can change the later hydraulic fluid pressure of damping orifice plate 24, thereby influence the aperture of the interior servovalve of enclosed pump 14 pumps; Cause the pressure reduction on it to change; Change owing to get into the pressure of enclosed pump 14 main pump internal variables control oil cylinder, during the in-oil cylinder spring action equilibrium of forces of this pressure and 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, changed the electric current that drives explosion-proof 3-position 4-way solenoid directional control valve 19, the speed of system changes thereupon.
When changing by 19 right electromagnet energisings of explosion-proof 3-position 4-way solenoid directional control valve, system is with inverted running, and the adjusting of its speed is still realized by the electric current of regulating explosion-proof proportional pressure-reducing valve 21.
(speed accelerates to the setting motion speed 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 motion speed when stopping), by the output characteristics decision that is connected the current regulating module on the explosion-proof proportional pressure-reducing valve 21.
Safety measure
In order to prevent enclosed pump 14 because of oil starvation damages, on the pressure oil circuit of enclosed pump 14 slippage pumps, oil compensation pressure signal emitter 22 has been installed, when oil compensation pressure was lower than 0.8Mpa, pressure transducer imported this into computer, and the control motor is shut down.
