Abstract
The present invention relates to concrete pump truck arm stabilising arrangement, especially a kind of pumping vehicle arm rack stabilization balanced valve.Concrete pump truck arm stabilization balanced valve, blocks up steel ball including for sequence valve, needle valve assembly, balanced valve valve body, oil, and described sequence valve is threaded in balanced valve valve body two ends；Described needle valve assembly is threadably mounted on balanced valve valve body, is used for regulating the sequence valve opening time；Described oil blocks up steel ball and is positioned at the oil duct of balanced valve valve inner, is used for blocking oil duct fabrication hole.The concrete pump truck arm stabilization balanced valve of the present invention, the pilot control oil circuit of overflow valve is changed into adjustable control by directly control, eliminate former one-way throttle valve, system is avoided to build the pressure heating, during making the operation of whole concrete pump truck arm control, jib action speed is adjustable, reaching concrete pump truck arm operation control performance good, jib swings little being difficult to because the most significantly swinging and fatigue damage.
Description
Technical field
The present invention relates to concrete pump truck arm stabilising arrangement, especially a kind of pumping vehicle arm rack stabilization balanced valve.
Background technology
Along with the continuous expansion of urban construction, concrete mixer application is more and more extensive, and my company also devises size
Little various pump trucks, all standard with reference to big pump truck design and manufacture, and are sold to hundreds of of market.But in actual use,
The proficiency level grasped due to user is different, and the degree that control jib rocks is the most different, when causing new user operation, it is impossible to very
Control jib well.
For this problem, in prior art, the balanced valve of Germany's import can make pumping vehicle arm rack protect to a certain extent
Keep steady fixed.But this balanced valve is one-way throttle valve, the pilot control oil circuit of overflow valve is directly to control, and the system of easily causing builds the pressure
Heating, during making the operation of whole concrete pump truck arm control, jib action speed is non-adjustable, makes concrete pump truck arm
Return amplitude of fluctuation fatigue damage greatly.
Summary of the invention
In order to solve the problems referred to above, helping new user preferably to manipulate pump truck, the present invention provides a kind of concrete mixer arm
Frame stabilization balanced valve.
The present invention solves its technical problem and the technical scheme is that concrete pump truck arm stabilization balanced valve, including for
The stifled steel ball of sequence valve, needle valve assembly, balanced valve valve body, oil, described sequence valve is threaded in balanced valve valve body two ends；Described
Needle valve assembly be threadably mounted on balanced valve valve body, be used for regulating the sequence valve opening time；Described oil blocks up steel ball and is positioned at flat
In weighing apparatus oil duct within valve body, it is used for blocking oil duct fabrication hole.
Described sequence valve is made up of overflow valve and check valve.
The concrete pump truck arm stabilization balanced valve of the present invention, can be according to jib by static state to dynamic transitional processes
Control requirement and be turned on and off arm support oil cylinder, directly control change the pilot control oil circuit of overflow valve into adjustable control
System, eliminates former one-way throttle valve, it is therefore prevented that system builds the pressure heating, makes whole concrete pump truck arm operation control process
Middle jib action speed is adjustable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the concrete pump truck arm stabilization balanced valve of the present invention；
Fig. 2 is the control principle drawing of the concrete pump truck arm stabilization balanced valve of the present invention.
Detailed description of the invention
As it is shown in figure 1, concrete pump truck arm stabilization balanced valve, including for HEX13 sequence valve 1, needle valve assembly 2, balance
The stifled steel ball 4 of valve body 3, oil, HEX13 sequence valve 1, each one of left and right, it is threaded in balanced valve valve body 3 two ends, HEX13 order
Valve is made up of overflow valve and check valve；Needle valve assembly 2 is that quenched part processed by No. 45 steel, is threadably mounted on balanced valve valve body 3, logical
Cross turn needle-valve rotate, can regulate sequence valve open time reach the purpose that pumping vehicle arm rack is stable, above nut for entering
Mouth thread seal.Balanced valve valve body 3 is No. 45 steel press forgings, and inside is all high-pressure oil duct, and the stifled steel ball 4 of oil is positioned at valve inner
In oil duct, it is used for blocking oil duct fabrication hole, prevents leakage of oil.
Fig. 2 is the control principle drawing of the concrete pump truck arm stabilization balanced valve of the present invention, as in figure 2 it is shown, A is four arm oil
Cylinder, B1, B2 are the needle valve assembly of the balanced valve of the present invention, and C1 C2 is overflow valve, and D1 D2 is check valve, and E is and oil cylinder rodless
Chamber interface, F is and cylinder rod chamber interface, and G is the oil inlet and outlet of the balanced valve of the present invention, and F is entering of the balanced valve of the present invention
Oil-out.
If G is high pressure hydraulic fluid port, H is oil return opening.Hydraulic oil is entered balanced valve by G, and the check valve D1 opened on balanced valve enters
Entering oil cylinder A rodless cavity promotes oil cylinder to stretch out.The hydraulic oil of oil cylinder A rod chamber enters the balanced valve of the present invention through F mouth, but because overflowing
Stream valve C2 turns off and check valve D2 ends, the rod chamber back pressure of oil cylinder A, and the pressure of F mouth will raise, and at this moment the pressure in E chamber also rises
Height, the pressure in two chambeies acts on overflow valve C2 jointly, and overflow valve C2 is opened, and the hydraulic oil of oil cylinder A rod chamber is through balanced valve
On overflow valve C2 return to balanced valve oil return opening H, complete the extending action of oil cylinder A.After oil cylinder A action, if loading, system
Pressure also gets off, then because being that the pressure in two chambeies acts on overflow valve C2 jointly, at this moment will turn down overflow valve C2, and make oil cylinder A action
Steadily, adjustable because of the needle valve assembly on B1, B2 again, its speed thus can be changed with metering pin valve assembly B1, B2, from
And change the stability of pumping vehicle arm rack.
