Abstract
The utility model relates to a mobile concrete pump cantilever crane stabilising arrangement, especially a pump truck cantilever crane anti -shake balanced valve. Mobile concrete pump cantilever crane anti -shake balanced valve includes for sequence valve, needle valve component, balanced valve valve body, oil plug steel ball, sequence valve threaded connection at balanced valve valve body both ends, the needle valve component screw thread install on the balanced valve valve body for adjust the sequence valve opening time, the oil plug steel ball be located the inside oil duct of balanced valve valve body for shutoff oil duct fabrication hole. The utility model discloses a mobile concrete pump cantilever crane anti -shake balanced valve changes the guide control circuit of overflow valve into adjustable flow control by direct control, and one -way throttle valve before having cancelled avoids the system to suppress hair fixer heat, makes whole mobile concrete pump cantilever crane operation controls in -process cantilever crane action speed adjustable, and it is good to reach mobile concrete pump cantilever crane operation control performance, and the cantilever crane swing is little difficult because of the swing fatigue damage by a wide margin that makes a round trip.
Description
Technical field
This utility model is related to concrete pump truck arm stabilising arrangement, especially a kind of pumping vehicle arm rack stabilization balanced valve.
Background technology
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,
Because the proficiency level that user grasps is different, control the degree that arm support rocks also different, lead to during new user operation it is impossible to very
Control well arm support.
For this problem, in prior art, the balanced valve of German import can make pumping vehicle arm rack protect to a certain extent
It is fixed to keep steady.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 whole concrete pump truck arm operational control, arm support action speed is non-adjustable, makes concrete pump truck arm
Return amplitude of fluctuation fatigue damage greatly.
Utility model content
In order to solve the above problems, new user is helped preferably to manipulate pump truck, this utility model provides a kind of concrete pump
Car arm support stabilization balanced valve.
This utility model solves its technical problem and employed technical scheme comprise that：Concrete pump truck arm stabilization balanced valve, bag
Include and block up steel ball for sequence valve, needle valve assembly, balance valve body, oil, described sequence valve is threaded in balance valve body two ends；
Described needle valve assembly is threadably mounted on balance valve body, for regulation order valve opening time；Described oil blocks up steel ball position
In the oil duct of balanced valve valve inner, for blocking oil duct fabrication hole.
Described sequence valve is made up of overflow valve and check valve.
Concrete pump truck arm stabilization balanced valve of the present utility model, can according to arm support by static to dynamic transitional processes
In control require being turned on and off arm support oil cylinder, the pilot control oil circuit of overflow valve is changed to adjustable throttling by direct control
Control, the heating it is therefore prevented that system builds the pressure that eliminates former one-way throttle valve, make whole concrete pump truck arm operational control
In journey, arm support action speed is adjustable.
Brief description
Fig. 1 is the structural representation of concrete pump truck arm stabilization balanced valve of the present utility model；
Fig. 2 is the control principle drawing of concrete pump truck arm stabilization balanced valve of the present utility model.
Specific embodiment
As 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 balance 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 balance valve body 3, leads to
Cross turn needle-valve rotation, can adjust sequence valve unlatching time reach the stable purpose of pumping vehicle arm rack, above nut be into
Mouth thread seal.Balance valve body 3 is No. 45 steel forging casting dies, and inside is all high-pressure oil duct, and the stifled steel ball 4 of oil is located at valve inner
In oil duct, for blocking oil duct fabrication hole, prevent oil leak.
Fig. 2 is the control principle drawing of concrete pump truck arm stabilization balanced valve of the present utility model, as shown in Fig. 2 A is four
Arm oil cylinder, B1, B2 are the needle valve assembly of balanced valve of the present utility model, C1 C2 be overflow valve, D1 D2 be check valve, E be with
Oil cylinder rodless cavity interface, F is and cylinder rod chamber interface that G is the oil inlet and outlet of balanced valve of the present utility model, and F is this practicality
The oil inlet and outlet of new balanced valve.
If G is high pressure hydraulic fluid port, H is oil return opening.Hydraulic oil enters balanced valve by G, and the check valve D1 opening 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 balanced valve of the present utility model through F mouth, but
Because overflow valve C2 turns off and check valve D2 cut-off, the rod chamber back pressure of oil cylinder A, the pressure of F mouth will raise, the at this moment pressure in E chamber
Also raise, the pressure collective effect in two chambeies, in overflow valve C2, is opened overflow valve C2, the hydraulic oil of oil cylinder A rod chamber is through flat
Overflow valve C2 on weighing apparatus valve returns to balanced valve oil return opening H, completes the extending action of oil cylinder A.After oil cylinder A action, if loading,
System pressure also gets off, then because be the pressure collective effect in two chambeies in overflow valve C2, at this moment will turn down overflow valve C2, make oil cylinder A
Stable action, and because the needle valve assembly on B1, B2 is adjustable, thus its speed can be changed with metering pin valve assembly B1, B2
Degree, thus changing the stability of pumping vehicle arm rack.
