One section of adjusting yoke and several headstock gear pull rods join end to end；Adjusting yoke is corresponded in the stop gate slot equipped with pull rod
Platform is dismounted, the Tiebar structure is corresponded on pull rod dismounting platform and is equipped with the fixed mechanism for being capable of fixing headstock gear pull rod, it is described
The adjusting yoke is corresponded on the cell wall of stop gate slot is equipped with the resettlement groove that can place adjusting yoke.
The fixed mechanism has support platform, and support platform is set to the track on the pull rod dismounting platform through idler wheel
On；The headstock gear pull rod is equipped with the support frame of the corresponding support platform.
A kind of stop gate maintenance hoisting method using the huge intake tower stop gate slot structure, it is characterised in that
Steps are as follows：
Hydraulic cylinder is lifted up Tiebar structure until the upper end for being connected to the headstock gear pull rod of adjusting yoke lower end is exposed
Pull rod dismounts on platform；
It is fixed by the headstock gear pull rod upper end that fixed mechanism will be exposed on pull rod dismounting platform；
Remove the connection structure between adjusting yoke and the headstock gear pull rod of its lower end connection；
Staff drives adjusting yoke to tilt to resettlement groove；
Hydraulic cylinder transfers adjusting yoke up to end in contact resettlement groove bottom under adjusting yoke；
Remove the connection structure between adjusting yoke upper end and hydraulic cylinder motion end；
Adjusting yoke is driven integrally to enter in resettlement groove by staff；
Hydraulic cylinder is transferred its motion end to upper end and is exposed at the headstock gear pull rod on pull rod dismounting platform, and passes through company
Binding structure is connect with the upper end of the headstock gear pull rod；
Hydraulic cylinder is lifted up stop gate through headstock gear pull rod, until stop gate is located on the inspection platform
Side.
The beneficial effects of the invention are as follows：The present invention dismounts platform and fixed mechanism by setting pull rod, with conveniently
Dismount the adjusting yoke in Tiebar structure.Increase the control stroke of hydraulic cylinder headstock gear by removing adjusting yoke, allows fast
The maintenance of fast gate, replacement water seal be easier, quick, safely, effectively rate.
