Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, stage performance vehicle is equipped with the vehicle of designed, designed using the second-class chassis of the lorries vehicles such as east wind, liberation mostly
End structure.Compartment is mainly made of compartment roof plate 1, both sides outside plate 2, two apodemas 3, bottom plate 4 and foreboard, back plate.If by compartment
Expansion formed performance stage, then requirement under HYDRAULIC CONTROL SYSTEM, first by top plate 1 together with hinged both sides outside plate 2 vertically to
On be increased to predetermined altitude, subsequent both sides outside plate 2 is extended around hinge joint to be flushed until with top plate 1, so as to formed performance dance
The ceiling of platform, around the hinge joint with bottom plate 4, outwards expansion flushes last two apodema 3 until with it, forms interim performance stage.
Stage performance area is designed according to carriage body construction and differed in size.It is larger in view of car sizes, therefore per side wall
Plate is required for 2 hydraulic cylinders to drive simultaneously, then each hydraulic cylinder for needing 4 same models of the action of the inside and outside plate in both sides is grasped
It is vertical.Meanwhile the lifting action of top plate also will respectively arrange 2 hydraulic cylinders to complete near forward and backward plate.Then the hydraulic pressure system altogether needs
12 hydraulic cylinders are equipped with, working cycles can be briefly described as follows：Top plate (together with two outer panels) rising → outer panel expansion → interior
Side plate expansion → interior plate closes up → and outer panel closes up → and top plate falls after rise.
Such as Fig. 2, design hydraulic control system completes more than working cycles and uncomplicated.Existing stage vehicle in the market,
Its hydraulic system uses tube valve connection mostly, and each control valve and connecting line are all disposed within the crossbeam lower part of automobile frame.This
Kind arrangement form good concealment does not influence vehicle appearance, but brings very big inconvenience to installation, debugging and maintenance, these work need
Personnel is wanted to manipulate in bottom of frame to complete, it is very inconvenient, and once break down, because pipeline connects intricate, searching
And repairing trouble point will all face very big difficulty.For disadvantage mentioned above, author proposes a kind of new hydraulic system of meter, the system
Compact-sized hydraulic pressure unit is formed using superposition valve group, and is arranged between driver's cabin and compartment, is operated convenient for personnel.
It is automatically controlled to realize, which mainly employs the Sandwich plate valve of 3 kinds of difference in functionality：3-position 4-way Y type Median Functions
Solenoid directional control valve, bidirectional hydraulic control check valve, Double throttle check valve.
The control valve of selection as above is because mainly considering following problem in the design of circuit.
(1) synchronization loop.Because each action that the system is completed is driven jointly by 4 hydraulic cylinders with model, institute
To require 4 cylinders as synchronous as possible.Realize that there are many synchronous mode：Such as mechanical synchronization, throttle grverning is synchronous, volumetric speed control is synchronous
Deng.The hydraulic system that control is closed for stage car exhibition uses throttle grverning synchronization loop more, including using throttle valve, shunting
The diversified forms such as valve and speed governing valve.Theoretically, flow divider can load the size of different automatic adjustment restrictions according to hydraulic cylinder, make
The flow entered in multiple hydraulic cylinders is identical synchronous to realize.However the inlet flow rate of its synchronization accuracy and flow divider in practice
It is square directly proportional, if flow is less than normal, will substantially reduce synchronization accuracy;In addition, synchronization accuracy also with flow divider in pipeline
In the Multiple factors such as position, the take over length between hydraulic cylinder and operating pressure it is related.Speed governing valve occurs in workload
The pressure differential of its throttle orifice can be automatically adjusted during variation, make by flow be held essentially constant, suitable for speed stability
Higher occasion.And during the exhibition of each carriage of stage vehicle is closed, load variation is less and to the stability requirement of the speed of service not yet
Height, author have selected throttle valve synchronization loop.
(2) speed limit circuit is balanced.In order to which compartment outer panel is overcome to close up, top plate fall after rise and interior plate be unfolded when because each plate from
Weight and be likely to occur acceleration fall the phenomenon that, i.e., hydraulic cylinder retract when generate it is " negative " load, counterbalance valve should be set on oil return line
Each plate dead weight is balanced to form back pressure, prevents from advancing by leaps and bounds, makes the speed of service held stationary as far as possible of hydraulic cylinder in each operating mode.It is comprehensive
2 points more than closing, meter out round trip synchronization loop can be formed using overlapping two, make the forward and reverse of hydraulic cylinder
Movement is all steady adjustable.
(3) circuit is locked.It, that is, after forming makeshift stage when each side plate is unfolded, and top plate is in lift location
It asks each Board position that cannot be mutated, to avoid danger, therefore bidirectional hydraulic control check valve (hydraulic pressure is set in each hydraulic circuit
Lock) to form locking circuit, enable hydraulic cylinder is upper at an arbitrary position to stop, and will not be moved after stopping due to external force acts on.It is logical
Any other Hydraulic Elements is not provided between bidirectional hydraulic control check valve and hydraulic cylinder in the case of often, it can No leakage to be ensured to occur
By locking circuit.But within the system, the gravity load of each plate is larger, easy during declining fast drop occur, stop alternately
The improper phenomenons such as discontinuous jump, vibration.It is larger this is mainly due to loading, excessive velocities when running downwards, hydraulic pump
Fuel delivery has little time to supplement the volume that hydraulic cylinder epicoele is formed for the moment, therefore is generating negative pressure in short-term into oil return line, causes to be in
The control pressure of hydraulic control one-way valve on oil return line decreases, closed check valve, and the oil return line of unexpected closed system makes hydraulic pressure
The movement of cylinder stops suddenly.After the pressure rise of in-line, the check valve of closing reopens, and loads rapid decrease again.
Above process is repeated, causes system oscillation downlink.For above-mentioned phenomenon is avoided to occur, one-way throttle can be installed on oil return line
Valve just can prevent negative pressure from generating.Therefore the system using superposing type bidirectional hydraulic control check valve after Double throttle check valve again with liquid
Cylinder pressure connects.
(4) arrangement form of control valve and pipeline.Therefore, author designed superposition valve type hydraulic system：In car steering
Hydraulic oil container is placed in junction between room and compartment, and will be selected by 12 groups of superposing type electromagnetic switch by more than principle
Valve, bidirectional hydraulic control check valve and Double throttle check valve a point two rows are directly installed on fuel tank upper plate by the oil path block of designed, designed
On, a compact hydraulic pressure unit is formed, in the system, each hydraulic cylinder is controlled respectively by independent one group of Sandwich plate valve, i.e.,
Hydraulic pressure pump output terminal is divided into 12 parallel branch oil circuits after overflow valve and drives 12 hydraulic cylinder works.The valve of entire hydraulic system
Group installation is neat, beautiful, and oil circuit is clear, pipeline is simple, only arranges 24 parallel branch oil pipes (with 12 hydraulic cylinders under vehicle frame
Oil inlet and outlet be connected), piece-ups are few, and fluid is not easy to leak；System debug is simply easy, breaks down and is also convenient for determining simultaneously energy
Investigation in time.
