The work process of the gantry beam lowering or hoisting gear of a kind of hydraulic control of the present invention is as follows: motor 6 starts,
When electromagnetic valve a11 access failure, hydraulic oil → motor 6 → check valve a7 → be directly entered fuel tank 5, this
Oil circuit is also protected by sample；Electromagnetic valve a11 energized action, electromagnetic valve a11 switch connection, hydraulic pressure
Oil is on the left of motor 6 → electromagnetic valve a11 → check valve d13 → pilot operated valve device 8, and on the right side of pilot operated valve device 8, oil passes through
Check valve c12 returns to fuel tank 5, connects on the left of pilot operated valve device 8；Hydraulic oil by motor 6 → check valve a7 →
The left chamber of two hydraulic cylinder a3-1-14 of pilot operated valve device 8 → electromagnetic valve b14 → electromagnetic valve c16 → simultaneously enter,
Two hydraulic cylinder a3-1-14 actions, roller b3-1-11 moves, and travel switch a3-2-18 opens, electromagnetism
Valve d17, electromagnetic valve e18, electromagnetic valve f20 obtain electric (electromagnetic valve d17 close, electromagnetic valve e18 open,
Electromagnetic valve f20 replaces).During owing to rising, motor 6 outlet hydraulic oil pressure is relatively low, and sequence valve 10 closes
Close, the oil return of two hydraulic cylinder a3-1-14 through electromagnetic valve c16 → check valve b9 → electromagnetic valve b14 →
Electromagnetic valve d17 respectively enters the left chamber of two hydraulic cylinder a3-1-14, two hydraulic cylinder a3-1-14 shapes respectively
Become differential connection, it is achieved rapid increase.Electromagnetic valve a11 power-off when lifting height is enough, returns to left side,
Motor 6 fuel feeding stops；To realize adjusting at a slow speed, only need to connect electromagnetic valve b14, electromagnetic valve b14 and obtain
Being electrically turn off, flow speed control valve 15 is connected, and motor 6 outlet pressure increases, and sequence valve 10 is connected, two hydraulic pressure
The oil return of cylinder a3-1-14 is through electromagnetic valve c16 → sequence valve 10 → fuel tank 5, raising speed on platform a3-1-1
Degree reduces.
If highly not enough, platform a3-1-1 continuation action, until reaching the pole of two hydraulic cylinder a3-1-14
Extreme position；Motor 6 continues fuel feeding, and in two hydraulic cylinder a3-1-14 cylinders, hydraulic fluid pressure increases, sequentially
Valve b19 connects, fuel feeding: hydraulic oil → sequence valve b19 → electromagnetic valve f20 → entrance hydraulic cylinder b3-2-4
Left chamber, hydraulic cylinder b3-2-4 action, platform b3-2-1 rises.Oil return: motor 6 outlet hydraulic oil pressure
Power is relatively low at ascent stage, sequence valve a10 close, hydraulic oil through electromagnetic valve f20 → check valve b9 →
Electromagnetic valve b14 → electromagnetic valve e18 → sequence valve b19 → electromagnetic valve f20 enters hydraulic cylinder b3-2-4, two
Hydraulic cylinder b3-2-4 realizes differential connection respectively, it is achieved rapid increase.Electromagnetic valve when lifting height is enough
A11 power-off, pilot operated valve device 8 returns to right side, and motor 6 fuel feeding stops, to realize adjusting at a slow speed, only
Need to connect electromagnetic valve b14, electromagnetic valve b14 and obtain electrically disconnected, flow speed control valve 15 is connected, motor 6 outlet pressure
Increase, sequence valve a10 connect, the oil return of hydraulic cylinder b3-2-4 through electromagnetic valve c16 → sequence valve a10 →
Fuel tank 5, the platform b3-2-1 rate of climb reduces.
The decline process of hydraulic system and uphill process basic simlarity.Its execution process is also from hydraulic cylinder
A3--1-14 starts, and first electromagnetic valve c16 obtains electric, and electromagnetic valve c16 commutates, then electromagnetic valve a11
Connecting, electromagnetic valve a11 energized action, electromagnetic valve a11 switch connection, hydraulic oil is from motor 6 → electromagnetism
On the left of valve a11 → check valve d13 → pilot operated valve device 8, on the right side of pilot operated valve device 8, oil is returned to by check valve c12
Fuel tank 5, connects on the left of pilot operated valve device 8；Hydraulic oil is by motor 6 → check valve a7 → pilot operated valve device 8 → electricity
Right chamber (the raising and lowering of two hydraulic cylinder a3-1-14 of magnet valve b14 → electromagnetic valve c16 → simultaneously enter
Realize differential principle identical).When hydraulic cylinder a3-1-14 homing, travel switch a3-2-18 closes
Close, electromagnetic valve d17, electromagnetic valve e18, tri-electromagnetic valves of electromagnetic valve f20 disconnect (electromagnetic valve d17 closes,
Electromagnetic valve e18 connects, electromagnetic valve f20 commutates), motor 6 continues fuel feeding, two hydraulic cylinder a3-1-14
Interior oil pressure increases, and sequence valve b19 connects.Hydraulic oil → sequence valve b19 → electromagnetic valve f20 → enter respectively
Enter two right chambeies of hydraulic cylinder b3-2-4.(hydraulic cylinder b3-2-4 declines process also can realize differential connection, with
Its uphill process is similar) during declining, arrive the position required, electromagnetic valve a11 power-off, liquid
Control valve 8 returns to right side, and motor 6 fuel feeding stops；To realize descending at slow speed, with the side risen at a slow speed
Method is similar, only need to connect electromagnetic valve b14, electromagnetic valve b14 and close, and flow speed control valve 15 is connected, motor 6
Outlet pressure increases, and sequence valve a10 connects, and oil return line is connected with fuel tank 5, and hydraulic cylinder b3-2-4 returns
Oil reduces through electromagnetic valve f20 → sequence valve a10 → fuel tank 5, platform b3-2-1 decrease speed, more than flat
Platform a3-1-1 with during the rise and fall of platform b3-2-1 crossbeam 1 can corresponding therewith rise or under
Fall, it is achieved that the lifting process of gantry beam.
