A kind of course of work of the gantry beam lifting gear of hydraulic control of the present invention is as follows：Motor 6 starts, and works as solenoid valve
During a11 access failures, hydraulic oil → 6 → check valve of motor a7 → is directly entered fuel tank 5, also oil circuit is protected in this way；Electricity
Magnet valve a11 energized actions, solenoid valve a11 switch connections, hydraulic oil is from 6 → solenoid valve of motor a11 → check valve d13 → pilot operated valve device
8 left sides, 8 right side oil of pilot operated valve device return to fuel tank 5 by check valve c12, and 8 left side of pilot operated valve device is connected；Hydraulic oil passes through motor 6 → mono-
To the left chamber of two hydraulic cylinder a3-1-14 of valve a7 → 8 → solenoid valve of pilot operated valve device b14 → solenoid valve c16 → while entrance, two liquid
Cylinder pressure a3-1-14 is acted, and idler wheel b3-1-11 movements, travel switch a3-2-18 is opened, solenoid valve d17, solenoid valve e18, electromagnetism
Valve f20 is obtained electric (solenoid valve d17 is closed, solenoid valve e18 is opened, solenoid valve f20 transpositions).During due to rising, 6 outlet hydraulic of motor
Oil pressure is relatively low, and sequence valve 10 is closed, and solenoid valve c16 → check valve b9 → electromagnetism is passed through in the oil return of two hydraulic cylinder a3-1-14
Valve b14 → solenoid valve d17 respectively enters the left chamber of two hydraulic cylinder a3-1-14, and two hydraulic cylinder a3-1-14 are respectively formed differential
Rapid increase is realized in connection.Solenoid valve a11 is powered off when lifting height is enough, is restored to left side, and 6 fuel feeding of motor stops；To reality
It now adjusts at a slow speed, only need to connect solenoid valve b14, solenoid valve b14 must be electrically turn off, and speed governing valve 15 is connected, and 6 outlet pressure of motor increases
Greatly, sequence valve 10 is connected, and the oil return of two hydraulic cylinder a3-1-14 is by solenoid valve c16 → 10 → fuel tank of sequence valve 5, platform a3-
The 1-1 rates of climb reduce.
If height is insufficient, platform a3-1-1 continues to act, the extreme position until reaching two hydraulic cylinder a3-1-14；Horse
Continue fuel feeding up to 6, hydraulic fluid pressure increases in two hydraulic cylinder a3-1-14 cylinders, and sequence valve b19 is connected, fuel feeding：Hydraulic oil → suitable
Sequence valve b19 → solenoid valve f20 → enter hydraulic cylinder b3-2-4 left chambers, hydraulic cylinder b3-2-4 actions, platform b3-2-1 rises.It returns
Oil：6 outlet hydraulic oil pressure of motor is relatively low in ascent stage, and sequence valve a10 is closed, and hydraulic oil is by solenoid valve f20 → unidirectional
Valve b9 → solenoid valve b14 → solenoid valve e18 → sequence valve b19 → solenoid valve f20 enters hydraulic cylinder b3-2-4, two hydraulic cylinders
B3-2-4 realizes differential connection respectively, realizes rapid increase.Solenoid valve a11 is powered off when lifting height is enough, and pilot operated valve device 8 is restored to
Right side, 6 fuel feeding of motor stop, and are adjusted at a slow speed to realize, only need to connect solenoid valve b14, solenoid valve b14 obtains electrically disconnected, speed governing
Valve 15 is connected, and 6 outlet pressure of motor increase, sequence valve a10 is connected, and the oil return of hydraulic cylinder b3-2-4 is by solenoid valve c16 → suitable
Sequence valve a10 → fuel tank 5, platform the b3-2-1 rate of climb reduce.

Begin, solenoid valve c16 is obtained electric first, solenoid valve c16 commutations, and then solenoid valve a11 is connected, solenoid valve a11 energized actions, electromagnetism
Valve a11 switch connections, hydraulic oil are oily on the right side of 6 → solenoid valve of motor a11 → check valve d13 → pilot operated valve device, 8 left side, pilot operated valve device 8
Fuel tank 5 is returned to by check valve c12,8 left side of pilot operated valve device is connected；Hydraulic oil passes through 6 → check valve of motor a7 → pilot operated valve device 8 → electricity
Magnet valve b14 → solenoid valve c16 → while right chamber (the differential principle of raising and lowering realization for entering two hydraulic cylinder a3-1-14
It is identical).When hydraulic cylinder a3-1-14 homings, travel switch a3-2-18 is closed, solenoid valve d17, solenoid valve e18, electromagnetism
Tri- solenoid valves of valve f20 disconnect (solenoid valve d17 is closed, solenoid valve e18 is connected, solenoid valve f20 commutations), and motor 6 continues fuel feeding,
Oil pressure increases in two hydraulic cylinder a3-1-14, and sequence valve b19 is connected.Hydraulic oil → sequence valve b19 → solenoid valve f20 → difference
Into two hydraulic cylinder b3-2-4 right chambers.(hydraulic cylinder b3-2-4, which declines process, can also realize differential connection, with its uphill process phase
Like) during decline, the position of requirement, solenoid valve a11 power-off are reached, pilot operated valve device 8 is restored to right side, and 6 fuel feeding of motor stops
Only；It is similar to the method for rising at a slow speed to realize descending at slow speed, solenoid valve b14 need to be only connected, solenoid valve b14 is closed, speed governing
Valve 15 is connected, and 6 outlet pressure of motor increase, sequence valve a10 is connected, and oil return line is connected with fuel tank 5, the oil return of hydraulic cylinder b3-2-4
By solenoid valve f20 → sequence valve a10 → fuel tank 5, platform b3-2-1 decrease speeds reduce, with upper mounting plate a3-1-1 and platform
