Problems solved by technology

[0008] 2) The workload of the low-position jack door is small, and the construction period is controllable; the workload of the high-position jack door is heavy, because the top pivot needs to be removed, there are many uncertain factors, and the construction period is uncontrollable, and the preparatory work of the high-position jack door is heavy, and the time is relatively tight
[0009] However, in the maintenance process of the low-level top door, it is necessary to adopt a supporting maintenance system to ensure the entire maintenance process

Embodiment 1

[0039] see figure 1 , a large-scale miter gate low top door bottom pivot maintenance system, which includes a bottom pivot hinge hole bolt removal tool 1 for removing the bottom pivot hinge hole bolt, the bottom pivot hinge hole bolt removal tool 1 is connected with A hydraulic pump station 3 for providing hydraulic power is connected; it includes a quick shift tooling 2 for the bottom pivot that has been removed, and the quick shift tool 2 for the bottom pivot is connected to the hydraulic pump station 3 . By adopting the maintenance system with the above-mentioned structure, it is possible to realize quick dismantling of bolts for hinged holes of the bottom pivot in a narrow space according to construction requirements. During the shifting process of the bottom pivot, the fast shift tooling of the bottom pivot moves forward along the track to ensure safe and fast moving out and return. The maintenance efficiency is improved, the maintenance period is shortened, the difficul...

Embodiment 2

[0049] The method for using the maintenance system of the low top door and bottom pivot of the large miter gate includes the following steps:

[0050] Step 1: Tighten the hexagonal bolts of the reaming hole; open the valve group 3 of the hydraulic pump station, supply oil to the tightening cylinder 6, and tighten the piston rod of the tightening cylinder 6 with the cylinder lock nut 8 to retract and tighten in place. pressure, close the valve group;

[0051] Step 2: Jack up and remove the hinged hole bolts; open the valve group 3 of the hydraulic pump station, and supply oil to the two sets of afterburner cylinders 4 at the same time, the piston rod of the afterburner cylinder rises, and it is attached to the bottom surface of the bottom pivot top cover to add force;

[0052] Step 3: The bottom pivot is in place; the bottom pivot is placed on the removal platform 16, and the hydraulic pump station 3 valve groups supply oil to the hydraulic cylinder 14, and the piston rod of th...

Abstract

The invention provides a large miter gate low-position top door and bottom pivot overhauling system and a using method. The large miter gate low-position top door and bottom pivot overhauling system comprises a bottom pivot hinged hole bolt dismounting tool used for dismounting a bottom pivot hinged hole bolt, and the bottom pivot hinged hole bolt dismounting tool is connected with a hydraulic pump station used for providing hydraulic power; the system comprises a bottom pivot rapid displacement tool used for moving out a removed bottom pivot, and the bottom pivot rapid displacement tool is connected with the hydraulic pump station. The maintenance efficiency is improved, the maintenance period is shortened, the maintenance operation difficulty is reduced, and the safety and reliability ofthe whole maintenance process are guaranteed.

Description

technical field [0001] The invention relates to a large-scale miter gate low-position top door and bottom pivot maintenance system and a use method, which are applied to the fields of disassembly and displacement of the top door and rear bottom pivot of large-scale miter gates. Background technique [0002] The force of the miter door of the ship lock is complex and the frequency of operation is high, which accelerates the wear of the bottom pivot ball tile and mushroom head, the damage of the seal, the blockage of the ball tile oil passage, etc., which affects the safe and stable operation of the miter door, and the door body needs to be lifted regularly. Bottom pivot inspection and repair. The bottom hinge of the miter door is mainly composed of bottom hinge top cover, bottom hinge ball tile, bottom hinge ball head, hinge hole bolt, backing plate and other parts. The main work of overhauling the bottom hinge of the miter door is to disassemble, remove, disassemble, repair...
