Description
Technical field
The present invention relates to a kind ofly with repairing with unload the rigid telescopic oil pipe of functional oil, belong to hydraulic machinery fluid conveying technology field.
Background technique
At present, Working mechanism on the increasing hydraulic machinery equipment requires to realize fore and aft motion or luffing motion, accomplishing more function, and the activation part of these mechanism's front ends generally all to need hydraulic pressure installation be that it provides power.Traditional hydraulic pipe line all realizes that through being arranged on Working mechanism outside or inner drag chain and flexible tubing promptly oil pipe is arranged on drag chain inside, and the crooked equal length of accomplishing oil pipe changes function.If yet drag chain and oil pipe are arranged on Working mechanism inside, can make that the space in the Working mechanism is narrow and small, install, dismantle and safeguard and all compare difficulty; If drag chain and oil pipe are arranged on Working mechanism when outer, then unfavorable Working mechanism is worked in narrow environment, can not protect oil pipe well, in case pipeline rupture or fracture might cause a serious accident.
Summary of the invention
The purpose of this invention is to provide a kind ofly with repairing with unload the rigid telescopic oil pipe of functional oil, can make the hydraulic working machine structure can not realize the length change function, design Fill valve and unloading valve simultaneously and guarantee the stable of oil circuit through drag chain.
The present invention adopts following technological scheme to realize: band repairing and unload the rigid telescopic oil pipe of functional oil; Comprise rigid telescopic pipe, Fill valve and oil drain valve; Pipe and outer tube in the rigid telescopic pipe comprises: pipe is nested in the rigidity outer tube as the adjustable pipe of telescopic oil tube in the rigidity; It is fixing to guarantee the constant amplitude motion that front tube puts the flexible or luffing device that is provided with Working mechanism on bayonet socket and the hydraulic machinery equipment; It is its fuel feeding that oil transportation hole foremost connects the hydraulic actuation parts, and the rigidity outer tube is connected through joint shaft bearing on the fixed arm of telescopic boom as the fixed tube of telescopic oil tube, and pipe is connected on the movable arm of telescopic boom in the rigidity; Fluid goes out oiler through the rigidity outer tube and is being communicated with outside oil circuit, and pipe connects hydraulic actuator in the rigidity; The import of Fill valve and the outlet of oil drain valve all are connected an end of oil return circuit, and the other end of oil return circuit communicates with fuel tank.
The pipe rear end is provided with step surface in said; The step surface diameter is greater than diameter of inner pipe; The outer tube front end is provided with step surface, and the step surface diameter is less than the outer tube diameter of bore, when interior pipe luffing is elongated to maximum position; Interior pipe step surface contacts with the outer tube step surface, and Guan Buhui deviates from the effect that outer tube plays position limitation protection in making.
Be provided with seal arrangement between said rigidity outer tube front end pipe box and the interior pipe pipe box and reveal to prevent oil pipe, seal arrangement is made up of rubber ring.
Said oil drain valve comprises oil drain valve's shell, emptying spool, pressure spring and unloads to unloading oilhole that the oilhole that radially unloads of oil drain valve only is communicated with the oil return fuel tank when not working.
Said Fill valve comprises Fill valve shell, repairing spool, pressure spring and repairing hole radially, when not working radially the repairing hole only be communicated with the telescopic oil tube oil circuit.
Working procedure of the present invention: the flexible or luffing device of Working mechanism links to each other on the bayonet socket in the rigidity on the pipe and the hydraulic machinery equipment.When operation mechanism made stretching, extension or luffing, it was poor to form the vacuum build-up of pressure in the oil pipe chamber, and the spool of Fill valve is to left movement at this moment, and the oil circuit of oil pipe inner chamber and oil sump tank is connected and eliminated vacuum; When the rigid telescopic oil pipe is made contractile motion, form oil pipe chamber inner high voltage, this moment, the spool of oil drain valve was wanted right motion, and the oilhole that radially unloads when the pressure of pressure Overpressure of a safety valve spring on the spool communicates with oil return circuit, and the telescopic oil tube inner fluid passes through oil drain valve's release.When operation mechanism did not move, the oil transportation hole of pipe was closed in the rigidity, and guaranteed synchronization telescope or luffing motion with Working mechanism because the existence of Fill valve and oil drain valve can guarantee that still the pressure in the rigid telescopic oil pipe is identical with oil returning tube this moment.
Advantage of the present invention is following:
1. the rigid telescopic oil pipe is arranged in Working mechanism inside, is convenient in narrow space, use;
2. adopt the rigidity oil pipe to supply the road, cancellation drag chain device, safe and simple;
3. adopt the secondary telescopic oil tube, significantly improve the variable-length of oil circuit;
4. adopt Fill valve and oil drain valve to implement repairing and off-load, guarantee that the rigidity oil pipe is capable of expansion and contraction;
5. the oil transportation hole of pipe can be closed in the rigidity, does not influence the fore and aft motion of Working mechanism
