Abstract
The utility model provides a kind of floating hydraulic control system, mainly solves the problem of bin gate easily causes to damage in operation process because of pressure after existing cold regenerative machine.The floating hydraulic control system can realize according to milling material number by rear bin gate lift cylinders rod chamber lead to oil pressure size realize after change of the bin gate to geostatic pressure；Meanwhile, the floating hydraulic control system can realize the floating of bin gate after cold regenerative machine, locked and elevating function.
Description
Technical field
The utility model provides a kind of floating hydraulic control system, is mainly used in the floating control of bin gate after cold regenerative machine.
Background technology
Cold regenerative machine is to utilize existing old pipeline material (surface layer or part basic unit), and whether matched somebody with somebody according to design level needs to add
The new aggregate in part, and it is proportionally added into a certain amount of regenerative agent (emulsified asphalt, foamed asphalt) or chemical stabilizer (cement, powder
Coal ash or lime etc.) and additive, complete the sprinkling of emulsified asphalt and water at a temperature of natural environment, the milling on old road and mix
With, the lifting of reworked material, pave and roller-compaction process of working continuously machine.
CN201320622605.5 discloses the patent of a kind of entitled " road surface cold in place recycling machine milling housing ", its technology
Scheme includes：" the road surface cold in place recycling machine milling housing includes the case for being used to cover milling cylinder, and case both sides are set
There are bin gate, back door oil cylinder after side plate, in addition to preceding bin gate, front door oil cylinder, floating, described case one end is hinged with preceding bin gate, separately
One end is hinged with bin gate after floating；The piston rod of front door oil cylinder on the outside of preceding bin gate with being hinged, for controlling preceding bin gate and milling to roll
The gap of cylinder, to control to be hinged after the pulverized size of milling material, the piston rod of back door oil cylinder and floating on the outside of bin gate, for controlling
Bin gate folding height after system, so as to which the reworked material after milling is polished.Although " be referred to by bin gate after floating in such scheme
Mode carry out operation, but often occur that rear bin gate is put down to the thrust hour milling material of milling material in actual use
Face injustice trailing wheel easily skids, and when thrust is big, the advance to cold regenerative machine brings additional friction, largely consumes engine
Power, makes tire be skidded during advance, causes cold regenerative machine slip loss excessively to increase, tire wear aggravation, or even makes
Into milling housing distortion.
Therefore, need badly provide it is a kind of can be to bin gate domain of walker is controlled after cold regenerative machine system.
The content of the invention
The utility model provides a kind of floating hydraulic control system, mainly solves after existing cold regenerative machine bin gate in operation
During easily because pressure cause damage the problem of.
Particular technique solution of the present utility model is as follows：
The floating hydraulic control system includes two-way high-pressure oil passage, and high-pressure oil passage includes three-position four-way electromagnetic directional valve all the way
And hydraulic lock, hydraulic oil pass sequentially through three-position four-way electromagnetic directional valve and hydraulic lock enter be used to control after bin gate thrust liquid
Compressing cylinder；Another road high-pressure oil passage includes two-position four-way solenoid directional control valve and electric proportional pressure-reducing valve, and hydraulic oil passes sequentially through electric ratio
Example pressure-reducing valve and two-position four-way solenoid directional control valve, which enter, is used for the hydraulic jack of bin gate thrust after control.Wherein hydraulic lock is used for
In the setting locked rear bin gate in operating position, electric proportional pressure-reducing valve is used for bin gate after being adjusted in working condition and milling material is compressed
Power.
It is preferred that, electric proportional pressure-reducing valve is made up of decompression overflow valve with electric proportional pressure control valve.
It is preferred that, the pressure gauge to milling material thrust for bin gate after display in real time is provided with electric proportional pressure-reducing valve,
In order to which staff can more be accurately controlled.
The utility model has the advantage of：
The floating hydraulic control system can realize according to milling material number by the logical oil of rear bin gate lift cylinders rod chamber
Change of the bin gate to the pressure on ground after the size of pressure oil is realized；Meanwhile, the floating hydraulic control system can realize it is cold again
The floating of bin gate, locked and elevating function after life.
Brief description of the drawings
Fig. 1 is the utility model principle schematic diagram；
Accompanying drawing is detailed as follows：
Bin gate lifts hydraulic jack after 1-；2- hydraulic locks；3- three-position four-way electromagnetic directional valves；4- system high pressure oil-outs；
5- fuel tanks；6- depressurizes overflow valve；7- electricity proportional pressure control valves；8- two-position four-way solenoid directional control valves；9- pressure gauges.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing, as shown in Figure 1：
This be used to controlling the floating hydraulic control system of bin gate after pavement cold recycling machine include hydraulic lock, one three
Four-way electromagnetic reversing valve, decompression overflow valve, electric proportional pressure control valve, two-position four-way solenoid directional control valve, pressure gauge,
Bin gate hoist cylinder after two.
High-pressure oil outlet point two-way, all the way into the pressure oil port (P mouthfuls) of three-position four-way electromagnetic directional valve, from 3-position 4-way
The fuel-displaced entrance hydraulic lock of A, B mouth of solenoid directional control valve, then the A for passing through hydraulic lock1、B1Hydraulic fluid port enters threeway, finally by three reduction of fractions to a common denominators
Not Jin Ru after two bin gate hoist cylinder rod chamber and rodless cavity.
The Y1a and Y1b of three-position four-way electromagnetic directional valve respectively it is electric can be achieved after bin gate elevating function, 3-position 4-way electricity
Bin gate can stop at the locking function of bin gate after any operating position, realization after magnetic reversal valve dead electricity.
When bin gate floating work after needs, another road binders of high-pressure oil outlet enters decompression overflow valve and electric proportional overflow
Valve group into electric proportional pressure-reducing valve in, two-position four-way solenoid directional control valve Y2 obtains electric, pressure oil enter oil cylinder rod chamber, rodless cavity
The direct oil return box of oil return.Bin gate drops to road surface in the presence of deadweight afterwards.Bin gate is compressed to milling material afterwards.According to road surface
The how many situation of milling material, the size of the electric proportional pressure control valve electric current of regulation, which can be realized into rear bin gate cylinder rod chamber, leads to oil pressure
Size so that thrust of the bin gate to milling material after changing.Have to the control handle of electric proportional overflow in driver's cabin
Thrust of the bin gate to milling material after being adjusted immediately according to surface state beneficial to operating personnel.
