Summary of the invention
The present invention will provide a kind of shield excavation machine cutter plate driver mechanism detachable slewing bearing fastening devices, its object is in order in work progress, once there is critical failure in shield excavation machine cutter plate driver mechanism's slewing bearing, the dismounting troubleshooting maintenance of parts can be carried out or upgrade, equipment run well and effectively works, thus ensureing that engineering can complete smoothly.
In order to achieve the above object, technical scheme of the present invention is:
The detachable slewing bearing fastening devices of a kind of shield excavation machine cutter plate driver mechanism, comprise slewing bearing, power block, power case lid, force transmission ring, storehouse, center, connecting bolt, cutter plate driver mechanism seals assembly, cutter plate driver mechanism, the static inner ring bolt of described slewing bearing is fixedly connected with power case lid, and headstock cover bolt is fixed on power block; Storehouse, center is fixedly connected with power case lid by bolt.
Drive pinion and drive pinion location bearing are also housed in described power block, and headstock covers mounted motor and reducing gear.
Described cutter plate driver mechanism seals assembly is made up of cutterhead face seal components and cutterhead radial seal assembly.
Described cutter plate driver mechanism front end face and periphery are by cutterhead face seal components by the force transmission ring that move and static power block clearance seal, and inner circumferential and rear portion end face pass through cutterhead radial seal assembly by the force transmission ring that moves and static storehouse, center clearance seal.
The invention has the beneficial effects as follows:
Slewing bearing and cutter plate driver mechanism seals assembly are installed and are positioned on force transmission ring by the present invention, and the motion outer ring bolt of slewing bearing is fixedly connected with force transmission ring, then integral assembling is on power block.Power case lid periphery is fixed by bolts on power block, and the static inner ring bolt of bearing is fixedly connected with power case lid.Storehouse, center is fixedly connected with power case lid by bolt.In work progress, shield excavation machine cutter plate driver mechanism's slewing bearing, once there is critical failure, can carry out the dismounting troubleshooting maintenance of parts or upgrade, equipment run well and effectively works, thus ensureing that engineering can complete smoothly.
In addition, cutter plate driver mechanism front end face and periphery are, by black box, the force transmission ring of motion and static power block are carried out clearance seal, and inner circumferential and rear portion end face are, by black box, the force transmission ring of motion and static storehouse, center are carried out clearance seal.Cutter plate driver mechanism seals effectively with complete be keep slewing bearing to clean, lubricate, the guarantee of normal temperature working environment, thus cutter plate driver mechanism can normally be run.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1 to 11, the detachable slewing bearing fastening devices of a kind of shield excavation machine cutter plate driver mechanism, comprise cutterhead face seal components 1, transmission ring 2, cutterhead radial seal assembly 3, storehouse, center 4, storehouse, center screw 5, power block bolt 6, drive pinion location bearing 7, power block 8, drive pinion 9, storehouse, center and power case lid connecting bolt 10, power case lid and power block connecting bolt 11, force transmission ring and floating bearing connecting bolt 12, slewing bearing 13, power case lid 14, slewing bearing and power case lid connecting bolt 15, motor and reducing gear 16, cutter plate driver mechanism seals assembly, cutter plate driver mechanism etc.
Slewing bearing 13 and driving mechanism black box are installed and are positioned on force transmission ring 2, and the motion outer ring bolt of slewing bearing 13 is fixedly connected with force transmission ring 2, then integral assembling is on power block 8; The static inner ring bolt of slewing bearing 13 is fixedly connected with power case lid 14, and power case lid 14 is fixed by bolts on power block 8; Storehouse, center 4 is fixedly connected with power case lid 14 by bolt.
Drive pinion 9 and drive pinion location bearing 7 are also housed, mounted motor and reducing gear 16 on power case lid 14 in power block 8.
Cutter plate driver mechanism seals assembly is made up of cutterhead face seal components 1 and cutterhead radial seal assembly 3.
The force transmission ring 2 of motion is carried out clearance seal with static power block 8 by cutterhead face seal components 1 by cutter plate driver mechanism front end face and periphery, and inner circumferential and rear portion end face are, by cutterhead radial seal assembly 3, the force transmission ring 2 of motion is carried out clearance seal with static storehouse, center 4.Cutter plate driver mechanism seals effectively with complete be keep slewing bearing to clean, lubricate, the guarantee of normal temperature working environment, thus cutter plate driver mechanism can normally be run.
Once because of overload, when the factors such as damage cause slewing bearing damage inefficacy need laid-up or upgrade, shield excavation machine should be parked in the soil property that the relatively hard region of soil property or people improve for slip casting, close screw machine to be unearthed gate, the shield excavation machine of jacking on one side, while start screw machine, shield machine head soil pressure is controlled between 0.30 ~ 0.35MPa, make cutterhead be subject to native power squeezing action and relatively stable time, bleed off the gear lubricant in power block, dismounting drive motors, power case lid, drive pinion and location bearing thereof, twist and remove the silently plug screw of power block axially and in radial direction, with bolt through this hole and pre-being threaded of relative position on force transmission ring, by axial bolts, force transmission ring is locked on power block, and storehouse, center is then locked with force transmission ring by radial connecting bolt, ensure that sealing station remains unchanged, sealing effectiveness is constant, outside stopping the soil body, muddy water enters in power block.Slewing bearing is exposed in open environment, leaves the working space that maintenance personal is enough for, thus make the maintenance of slewing bearing, upgrade and become feasible, can realize.
