Working principle: the working procedure of hydraulic automatic grabbing beam comprises contraposition, wears axle, takes off these three processes of axle
Contraposition refers to the process that grasping beam body 1 hanging axis center is aimed at center, gate lifting eye 3 hole.Decline close to gate (during by lifting thing) when grasping beam body 1 and complete after mechanical contraposition (locating stud 2 enters gate abutment sleeve) fixes the position all around of grasping beam, along with the further decline of grasping beam, the second piston rod 9 in gate lifting eye 3 top plate contact contraposition signal hydraulic controller 7, and push away on the second piston rod 9, oil in second oil cylinder 8 is pressed to the second fuel tank 11 be positioned on hoist by the second piston rod 9 by oil circuit, along with grasping beam continues to decline, the second liquid level sensor 12 in second fuel tank 11 continues to pass the signal to control panel, when second piston rod 9 reaches range minimum value, grasping beam just in time drops on gate, second liquid level sensor 12 sends signal (altimeter of lifting mechanism also can send signal when lifting mechanism drops to maximum position simultaneously) lifting mechanism power-off shutdown simultaneously, grasping beam stops declining, contraposition process completes, can carry out wearing axle action.
Hydraulic pressure is worn the iron 19 that the bearing pin 18 of shaft device 4 stretches out and is connected with the first piston bar 13 wearing axis signal hydraulic controller, after pump 20 starts, pump 20 is worn shaft device loop 6 by hydraulic pressure and is added oil to rodless cavity, and hydraulic oil enters rodless cavity, and axle is worn in bearing pin 18 reach.Bearing pin 18 drags first piston bar 13 by iron 19 and moves forward, hydraulic oil in loop is sucked the first oil cylinder 14 from the first fuel tank 15 be positioned at hoist by first piston bar 13, liquid level sensor 16 on first fuel tank 15 built-in first, first time liquid level sensor 17, when bearing pin 18 is close to range, in first fuel tank 15, hydraulic oil oil level is down to lower first time liquid level sensor 17 and is answered in scope, first time liquid level sensor 17 continues to pass the signal to control panel, when bearing pin 18 arrives maximum position, oil level is down to minimum, first time liquid level sensor 17 sends signal pumping plant and quits work, wear axle action to complete.
Take off axle action and wear axle action on the contrary, hydraulic oil enters the rod chamber that hydraulic pressure wears shaft device 4, moves de-axle after bearing pin 18.Bearing pin 18 moves after dragging first piston bar 13, hydraulic oil is pressed into the first fuel tank 15 by first piston bar 13, when bearing pin 18 is close to minimum stroke, in first fuel tank 15, hydraulic oil oil level gos up in liquid level sensor 16 induction range on first, on first, liquid level sensor 16 continues to pass the signal to control panel, and when bearing pin 18 arrives minimum position, oil level rises to the highest, on first, liquid level sensor 16 sends signal pumping plant and quits work, and de-axle action completes.
After grasping beam departs from gate, the second piston rod 9 in contraposition signal hydraulic controller 7 is repositioned to initial conditions under return spring 10 acts on.What so far hydraulic automatic grabbing beam was complete completes a grasping beam action.
