Description
Technical field
This utility model is related to a kind of brick machine distributing vehicle hydraulic means.
Background technology
In country's brick machine distribution device, the rotation of shaft is rotated all with conventional motors at present, and traditional
The drive mechanism that motor drives has the defect of itself.It is constant with the matching used reductor speed reducing ratio of conventional motors, so defeated
Go out invariablenes turning speed constant, and stir direction of principal axis and can not realize frequently commutation.If driving shaft to be rotated with conventional motors
Cloth, in pressing unfired brick, especially brick machine is suppressing Brick with blind hole and during special form brick, due to its die cavity than standard brick die cavity more
Plus it is complicated, so being more prone to cause cloth uneven.Whether cloth uniformly determines unfired brick quality, and cloth inequality adobe will
The problems such as concentric reducer, narrow waist occur is so as to cause the increase of production cost, while press can incline when press is depressed, shortens
Press service life, is also possible to bring potential safety hazard when serious.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of cloth more uniform brick machine distributing vehicle
Hydraulic means.
In order to achieve the above object, brick machine distributing vehicle hydraulic means of the present utility model is to employ the following technical solutions
Come what is realized：Including hydraulic pump, pressure compensator, hydraulic motor group, proportional direction valve and computer control system and coding
Device, hydraulic pump provide pressure oil and reach hydraulic motor group, pressure compensator by oil guide pipe Jing pressure compensators, proportional direction valve
It is made up of uniform-pressure-drop valve and shuttle valve, shuttle valve is in parallel with hydraulic motor group, uniform-pressure-drop valve is connected on hydraulic pump and proportion directional
Between valve.
Used as to further improvement of the utility model, hydraulic pump uses load-reacting pump, in hydraulic motor
A pair safe valve groups of group two ends parallel connection, a filter of connecting on the oil circuit between hydraulic pump oil-in and fuel tank, in hydraulic pressure
A relief valve of connecting on the oil circuit between hydraulic fluid port and fuel tank is pumped out, radiator is provided with fuel tank.
Using load-reacting pump supply hydraulic fluid, pump output flow can according to load demand output, subtract
Little power loss, the pressure compensator matched somebody with somebody ensure that proportional direction valve oil inlet and outlet pressure reduction keeps constant, located at hydraulic pump and liquid
Proportional direction valve between pressure motor is used for commutation and the rotating speed for controlling hydraulic motor, and the encoder of outfit is used to observe hydraulic pressure horse
Up to rotating speed, computer control system provides signal for proportional direction valve, is provided to the safe valve group at hydraulic motor group two ends to liquid
Pressure motor group plays a part of safeguard protection, and the relief valve being provided between hydraulic pump and fuel tank plays overload to system and device
The effect of protection, the radiator of outfit guarantee that oil temperature rising is little, and the filter of outfit is used to remove the impurity in hydraulic oil, makes liquid
Pressure device is working properly.
Description of the drawings
Fig. 1 is brick machine distributing vehicle hydraulic means schematic diagram described in the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in figure 1, a kind of hydraulic means for being applied to brick machine charge car, including hydraulic pump 3, pressure compensator 4, liquid
Pressure motor group 5, safe valve group 6, proportional direction valve 7, relief valve 8, radiator 1, filter 2 and computer control system and volume
Code device, hydraulic pump are load-reacting pump, and the offer pressure oil of hydraulic pump 3 is by oil guide pipe Jing pressure compensators 4, proportion directional
Valve 7 reaches hydraulic motor group 5, and pressure compensator 4 is made up of uniform-pressure-drop valve and shuttle valve, and shuttle valve is in parallel with hydraulic motor group 5, fixed
Difference pressure-reducing valve is connected between hydraulic pump 3 and proportional direction valve 7.5 two ends of hydraulic motor group parallel connection a pair safe valve groups 6,
Connect on oil circuit between 3 oil-in of hydraulic pump and fuel tank a filter 2,
Connect on oil circuit between 3 oil-out of hydraulic pump and fuel tank a relief valve 8, radiator is provided with fuel tank
1, encoder is arranged on hydraulic motor.
During work, hydraulic pump supply hydraulic fluid, when the device necessary flow increases, hydraulic pump discharge increase, when the dress
When putting necessary flow reduction, hydraulic pump discharge reduces, and Jing pressure compensators, proportional direction valve to hydraulic motor group drive hydraulic pressure horse
Up to rotation, pressure compensator ensures that proportional direction valve oil inlet and outlet pressure reduction keeps constant, the flow of such passing ratio direction valve
Just by Valve Core for Proportional Direction Valve openings of sizes determining.Computer control system sends signal, is changed by controlling proportional direction valve
Always hydraulic motor positive and negative rotation is controlled, hydraulic motor rotary speed is controlled by controlling proportional direction valve valve core opening size, lead to
Cross encoder and can observe whether hydraulic motor is carried out under the rotating speed of regulation.Hydraulic motor passes through sprocket wheel chain-driving charge car
Shaft positive and negative rotation stirs material, and such charge car cloth is more uniform, and repressed brick base quality is higher, especially carries in compacting
It is better obvious during the special form brick of core rod.
