Specific embodiment
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings：
See Fig. 1-Fig. 2, a kind of reliable location structure of narrow face copper plate of crystallizer including adjusting wide hydraulic cylinder 10, adjusts wide hydraulic pressure
The piston rod 1 of cylinder 10 connects narrow face copper plate of crystallizer 11；Locking mechanism 2 is provided on wide hydraulic cylinder 10 in described adjust, it is described
Locking mechanism 2 is socketed on the piston rod 1 for adjusting wide hydraulic cylinder 10, and cavity is equipped in the locking mechanism 2 of 1 side of piston rod,
Lock sleeve 7, pressing sleeve 6, locker piston 5 and disc spring 9 are provided in cavity, the pressing sleeve 6 is slided with lock sleeve 7 by lozenges
Connection, the wide hydraulic cylinder piston rod 1 of 7 apical grafting tune of lock sleeve, the both ends difference apical grafting disc spring 9 and locker piston 5 of pressing sleeve 6, setting
The side cavity for having disc spring 9 is equipped with exhaust outlet 8, and the side cavity for being provided with locker piston 5 is equipped with air inlet 3, the air inlet 3
Connect high pressure gas control valve 4.
The locking mechanism 2 is fixed on piston rod 1 and exports on cylinder cap.
A kind of localization method of narrow face copper plate of crystallizer：
1) air-cylinder type locking mechanism 2 is mounted on 4 piston rods 1 for adjusting wide hydraulic cylinder 10, locking mechanism 2 is fixed on work
Stopper rod 1 is exported on cylinder cap, brace foundation of wide 10 cylinder body of hydraulic cylinder as locking mechanism 2 is adjusted, when control valve 4 is in unloading condition
When, the pressing sleeve 6 of locking mechanism 2 moves right under the action of disc spring 9, tightly will by the wedge surface between pressing sleeve 6 and lock sleeve 7
Lock sleeve 7 is held out against on the piston rod 1 for adjusting wide hydraulic cylinder 10, and at this moment piston rod 1 is in " locking " state；When air inlet 3 is passed through
During pressed gas, high pressure gas pushes locker piston 5 to move to left, and pressing sleeve 6 is pushed to move to left, and disc spring 9 is compressed, and 9 side of disc spring is empty
Intracavity gas is discharged by exhaust outlet 8, and the pressure that pressing sleeve 6 is applied on lock sleeve 7 is released from, 7 clamping piston bar 1 of lock sleeve
Power also releases therewith, and at this moment piston rod 1 is in " unlock " state.
The direction of " left side " and " right side " represented by attached drawing described in this law is bright.
2) 11 locking means of narrow face copper plate of crystallizer：4 are adjusted wide hydraulic cylinder 10 and 4 locking mechanisms 2 thereon to form and adjust
Wide system during locking mechanism 2 " unlock " state, adjusts wide hydraulic cylinder 10 to adjust wide action；The location determination of narrow face copper plate of crystallizer 11
Afterwards, wide 10 stopping of hydraulic cylinder is adjusted to act, locking mechanism 2 " locking ", narrow face copper plate of crystallizer 11 is immovable.
3) see the control principle that Fig. 3 is the wide hydraulic cylinder 10 of tune and its locking mechanism 2,4 controlling parties for adjusting wide hydraulic cylinder 10
