Description
Technical field：
The utility model belongs to concreting machinery technical field, is related to a kind of concreting machinery pumping machine tilt cylinder, especially
It is that a kind of signal hydraulic fluid port merges with inlet (outlet), the tilt cylinder of Impact in Hydraulic System can be reduced.
Background technology：
Tilt cylinder is one of important component of concrete pump, and tilt cylinder realizes the pump of concrete pump with master cylinder alternating movement
Function is sent, when tilt cylinder moves to bottom, master cylinder action, conversely, when master cylinder is moved to the end, tilt cylinder action；Be provided with tilt cylinder into
Hydraulic fluid port, oil outlet, signal hydraulic fluid port.Each hydraulic fluid port position of traditional tilt cylinder as shown in Figure 1, signal hydraulic fluid port into and out of between hydraulic fluid port,
Tilt cylinder piston is moved to the left, and by (such as figure position) during signal hydraulic fluid port, signal oil notice master cylinder is sent at tilt cylinder signal port and is changed
To.But if signal hydraulic fluid port position is different, open pore size is not of uniform size, and the opportunity of notice master cylinder commutation is just different.Signal oil
While master cylinder commutation is notified, tilt cylinder travels forward until bottom.When reaching bottom, no longer demand hydraulic oil.Tradition pendulum
When cylinder reaches bottom, master cylinder commutation remains unfulfilled.Hydraulic oil is supplied always by oil pump, in the case of space invariance, oil
Liquid has nowhere to run.Pressure gradually rises, and tilt cylinder, each pipeline, connector, arm support, main pump are caused to impact, make system oil temperature rise,
It is required that engine power increase overcomes impact.Reduce reliability and service life.Therefore, seek to design a kind of concreting machinery pumping pendulum
Cylinder, signal hydraulic fluid port is merged with tilt cylinder inlet (outlet).When tilt cylinder starts action, signal notice master cylinder commutation is sent immediately.It is main
The time of cylinder reversal valve movement moves the time to the end close to tilt cylinder, the piston of tilt cylinder is moved to the bottom of tilt cylinder cylinder body
When, master cylinder commutation is just completed, and the pressure oil for pumping generation is just transferred to master cylinder from tilt cylinder, and driving master cylinder moves ahead.There is no biography
Tilt cylinder of uniting is such, and signal sends late, and in place, commutation has not been completed in master cylinder to tilt cylinder.The fluid that pump produces has nowhere to run, can only
Flowed by gap between limited part.Flowing is not smooth, produces high pressure.After high pressure, master cylinder commutation is completed, and fluid has place
Flow.Pressure declines suddenly again, causes to impact.After new-type tilt cylinder use, pressure peak is detected by instrument, than traditional tilt cylinder
Drop by half or so.Reduce system liquid voltage crest value, it is possible to improve the component longevity such as tilt cylinder, each pipeline, connector, arm support, oil pump
Life, reduces engine power demand, improves the reliability of whole equipment.
Utility model content：
The goal of the invention of the utility model is to overcome shortcoming existing in the prior art, proposes to design a kind of concreting machinery
The defects of pumping machine tilt cylinder, Impact in Hydraulic System caused by overcome traditional tilt cylinder is big, solve Impact in Hydraulic System and cause greatly
The problem of each pipeline, connector, arm support, oil pump equivalent life reduce, solves Impact in Hydraulic System and causes system oil temperature rise, reliable greatly
Property reduce, service life reduction the problem of, overcome increase engine power the defects of.
In order to realize above-mentioned purpose of utility model, the concreting machinery pumping machine tilt cylinder that the utility model is related to, it is led
Body structure includes piston rod, piston, oil inlet, oil outlet, signal hydraulic fluid port, tilt cylinder cylinder body, rodless cavity, rod chamber；Piston rod
One end is connected with piston, is sealed between piston and tilt cylinder cylinder body, and piston can be slided along tilt cylinder inboard wall of cylinder block, and rodless cavity is tilt cylinder
On the right side of cylinder body inner carrier without bar cavity, rod chamber is has bar cavity on the left of tilt cylinder cylinder body inner carrier；Oil inlet is opened in no bar
The upper right quarter of chamber, is connected with one end hydraulic fluid port of oil pump；Oil outlet is opened in the upper left quarter of rod chamber, and the fluid of outflow is through cooling oil
It is connected after case cooling with the other end hydraulic fluid port of oil pump；A diameter of 1~4mm of signal hydraulic fluid port, is arranged on the right side of oil inlet, and
Signal hydraulic fluid port is communicated with oil inlet, realizes merging for signal hydraulic fluid port and oil inlet, and signal hydraulic fluid port is connected with external control system,
Control master cylinder commutation.
When the utility model is used, hydraulic oil is pushed away out of oil inlet entering signal hydraulic fluid port and tilt cylinder cylinder body rodless cavity
Piston and piston rod are moved to the left from tilt cylinder cylinder body low order end bottom, and the hydraulic oil in rod chamber is flowed out from oil outlet, is being put
When cylinder starts action, signal notice master cylinder commutation is sent immediately；The diameter of reasonable setting signal hydraulic fluid port matches with tilt cylinder size,
Make the time of the time that master cylinder reversal valve moves close to tilt cylinder movement to the end, when piston is moved to tilt cylinder cylinder body high order end soon,
Master cylinder commutation is just completed, and the pressure oil that oil pump produces, which is just given, supplies master cylinder, and the pressure peak of hydraulic oil reduces in tilt cylinder cylinder body,
Tilt cylinder is avoided to cause greater impact.After master cylinder commutation is mobile, tilt cylinder stopping action.Master cylinder to the end after, be arranged symmetrically in addition
One tilt cylinder action, drives the piston in above-mentioned tilt cylinder cylinder body and piston rod to move right together, and tilt cylinder recovers described herein
Original state, next circulation start.
Compared with prior art, signal hydraulic fluid port merges the utility model with tilt cylinder oil inlet and outlet, reduce tilt cylinder, each pipeline,
The impact of connector, arm support, improves each component life；Oil temperature in hydraulic system reduces, and system reliability and service life improve；Reduction is started
Acc power demand；Its overall construction design is simple, and financial cost is low, and scientific in principle is safe and reliable to operation, and application environment is friendly.
