Seal is set at A1-A4.
Below to how using the hydraulic locking apparatus of the present embodiment to realize that the locking of filmatic bearing and roll and dismounting are entered
Row explanation：
During locking, hydraulic trolley fuel inlet fitting is connected with the first joint P1, back leakage connection is connected with the second joint P2.Open
Hydrodynamic pressure dolly, hydraulic oil is input in the first oil pocket A, producing axial force makes U-shaped oil cylinder 10 hold out against snap ring 52, promotes simultaneously
Coupling mechanism force is delivered to thrust bearing 120, so as to which filmatic bearing to be axially assembled to roll 200 by pushing member 20 to left movement
On.Sticking department 40 is installed in locking afterwards in place, it is held out against pushing member 20, so as to prevent pushing member 20 from moving back.Finally by liquid
Pressure dolly joint pulls out completion locking work.
During dismounting, tight lock part 40 is exited；The fuel inlet fitting of hydraulic trolley is connected with the second joint P2, back leakage connection and
One joint P1 connections；Start hydraulic trolley, hydraulic oil is input to the second oil pocket B of locking device, hydrodynamic force makes door
30 move to left the end face for holding out against roll 200, while promote pushing member 20 to move to right, and the second pushing part 23 of pushing member 20 drives case
Cap assemblies 130 are moved right together, filmatic bearing is separated with roll 200, and hydraulic trolley joint finally is pulled out into completion dismounting work
Make.
In summary, U-shaped fluid pressure type locking device of the invention improves locking compared to existing mechanical lock
Precision and speed, reduce operating personnel's working strength and the possibility of accident occurs, extend the service life of retaining mechanism.And
And U-shaped fluid pressure type locking device of the invention uses U-shaped oil cylinder, therefore compact-sized, device axial dimension is small, fully profit
With radial space, expand oil chamber volume, therefore, bigger coupling mechanism force can be provided in same oil pressure, and original need not be changed and rolled
Roll structure and size, therefore the improvement cost of roll structure will not be produced.
