With reference to Fig. 6, the hydraulic principle that a kind of flexible axle powered of long-acting design transmits Hydraulic Deviation-correcting Device is: oil pump is from the oil suction of fuel tank process oil suction filter, in the time that pressure is less than the rated pressure of pressure valve, hydraulic oil promotes change-over valve core, makes oil cylinder right side and fuel tank conducting, and hydraulic oil arrives oil cylinder left side simultaneously, promote piston rod, oil cylinder right side hydraulic oil is got back to fuel tank, and piston rod stretches out, and promotes the outside aligning carrier roller being attached thereto.If oil pump is worked always, certainly will cause system pressure to increase, in the time that its oil pump goes out oil pressure and is greater than the rated pressure of pressure valve, pressure valve spool is opened, and promotes unloader valve spool, by the fuel-displaced oil pump oil sump tank that directly draws, the oil pressure that goes out of laying down oil pump approaches zero-bit, oil pump idle running.So just can make the flexible axle being connected with oil pump not bear high moment of torsion, extend flexible axle service life, reach the object of protection flexible axle.
the invention has the beneficial effects as follows:
1. the design of the series of apertures on hollow shaft or elongated slot design have solved the flexible problem of flexible axle in inspection driving device control process.Flexible axle sheath and hollow shaft, rotate with flexible axle simultaneously, solved the apparent harm that flexible axle brings with the friction of sheath in the process of working long hours.
In flexible axle access fuel tank entrance when oil pump higher than hydraulic oil liquid level, do not have the hidden danger of hydraulic oil leakage of oil, the connection mode variation of flexible axle and oil pump power input shaft, flexible axle can directly be connected with oil pump power input shaft on the one hand, because flexible axle can solve the diff-H of flexible axle at fuel tank inflow point and oil pump to a certain extent; Flexible axle also can pass through fuel tank axle on the other hand, and sprocket wheel link chain mechanism or gear mechanism are connected with oil pump, and transmission of power is reliably effective.
3. the integrated all hydraulic element of hydraulic efficiency pressure system except oil cylinder in fuel tank; hydraulic efficiency pressure system arrangement than current Hydraulic Deviation-correcting Device has reduced many leak points; oil pump shaft sealing member is below hydraulic pressure pasta; obtain good lubrication and protection; its life-span can be not affected by environment; the most difficult problem of current Hydraulic Deviation-correcting Device can be solved well, the reliability of very high system can be obtained.
4. when under the condition that idler for belt conveyer spacing allows, oil cylinder is arranged in integrated fine strain of millet outside, can turn to parallelly with integrated fine strain of millet when transportation, and convenient transportation, protects whole equipment to a greater extent.
5. common Hydraulic Deviation-correcting Device there will be such operating mode: in the time that oil cylinder runs to the limit, inspection driving device still with belt friction, the overflow of hydraulic efficiency pressure system by pass valve, oil pump continues to turn round under the highest operating mode of system.Under this operating mode, flexible axle bears long-time reverse stress, very easily damages.The design of Load Relief System of the present invention can, under this operating mode, be unloaded the load of oil pump carrying to approaching zero-bit, removes the high moment of torsion that flexible axle bears, thereby reaches the effect of protection flexible axle.Unloader valve and change-over valve also have the function of the fault of automatically terminating simultaneously, run into the situation of spool blocking, only need to, through a rectification machine working cycle, just can automatically terminate fault.
