In cylinder pressure (305) and the second crude liquid cylinder pressure (311), by the first crude liquid cylinder pressure (305) and the second crude liquid cylinder pressure
(311) the described first thin hydraulic cylinder (309) and the second thin hydraulic cylinder (314) for being connected on tail portion are pushed respectively, thus altogether
Rise with promotion vehicle-carrying plate;
When vehicle-carrying plate needs to decline, twin-stage overflow valve (2) the low-pressure end overflow is opened, and the solenoid directional control valve (201) is right
Side movement, the manual bi-bit bi-pass reversal valve (304) of first electromagnetism and the manual bi-bit bi-pass reversal valve of second electromagnetism
(310) it acts, first hydraulic control one-way valve (303) and second hydraulic control one-way valve (312) are reversely opened, and oil inlet oil circuit is walked
To the top hydraulic fluid port of the described first thin hydraulic cylinder (309) and the second thin hydraulic cylinder (314), piston decline is pushed, thus point
Not Tui Dong the two concatenated first crude liquid cylinder pressures (305) and the second crude liquid cylinder pressure (311) decline, then off-load hydraulic oil
From the first crude liquid cylinder pressure (305) and the second crude liquid cylinder pressure (311) first hydraulic control one-way valve of bottom (303) and second
Hydraulic control one-way valve (312) returns to fuel tank, so that vehicle-carrying plate be driven to decline.
If because when the speed asynchronous (difference in height is excessive) of individual cylinders need to supplement oil inlet, the supplement oil inlet motor (6)
It drives the supplement oil-feed pump (7) to act, carries out supplement oil inlet;Such as: when the first crude liquid cylinder pressure (305) is too low, institute
Supplement oil inlet motor (6) starting, movement on the right side of first three-position four-way electromagnetic directional valve (302) are stated, institute is passed through in supplement oil inlet
It states the first three-position four-way electromagnetic directional valve (302) and the first hydraulic control one-way valve (303) enters master cylinder, accelerate the upper of this oil cylinder
It rises, to reduce the difference in height of the cylinder;When the described first thin hydraulic cylinder (309) of this side rise it is excessively high when, then described second
Movement on the right side of three-position four-way electromagnetic directional valve (307), third hydraulic control one-way valve (316) reverse opening is drained the oil, to make institute
It states the first thin hydraulic cylinder (309) and drops to normal level.When the first thin hydraulic cylinder (309) is too low, then described two or three four
It is opened on the left of electric change valve (307), supplement oil inlet passes through the third hydraulic control one-way valve (316) and the first unidirectional tune
Fast valve (306) enters in series connection oil circuit, to make the described first thin hydraulic cylinder (309) accelerate, until the height with other cylinders
Within the allowable range, the supplement oil inlet principle of other cylinders is identical for degree difference.
When needing declines garage manually: when having a power failure, pulling the manual bi-bit bi-pass reversal valve of first electromagnetism
(304) and the operating stick of the manual bi-bit bi-pass reversal valve (310) of second electromagnetism, while the operating stick of manual pump (8) is depressed,
At this moment the manual bi-bit bi-pass reversal valve (304) of first electromagnetism and the manual bi-bit bi-pass reversal valve (310) of second electromagnetism
It opens, first hydraulic control one-way valve (303) and second hydraulic control one-way valve (312) reverse opening, oil cylinder is in vehicle-carrying plate
Emptying to fuel tank, vehicle-carrying plate decline unclamps the manual bi-bit bi-pass commutation of first electromagnetism when falling into place under gravity
The operating stick of valve (304) and the manual bi-bit bi-pass reversal valve (310) of second electromagnetism, emptying stop, and vehicle-carrying plate decline stops,
Bus can be made conveniently to output;To nor affect on the trip of bus vehicle when making and having a power failure.
