Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making the creative labor
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in figures 1 to 6, a kind of open type TBM drives lifting apparatus, including guide post 5 and several lift cylinders 2, carries
Oil-lifting jar 2 is circumferentially mounted on the outer wall of bottom shield 3, and preferably lift cylinder has 4, is uniformly mounted on the four of bottom shield
The lower end in week, guide post 5 is set in the inside of bottom shield 3 and is matched with bottom shield, is only allowed between guide post and bottom shield
There are vertical direction displacements.The top of guide post 5 is connected with cutter plate driver 1 by bolt, and the top of guide post 5 is equipped with lower key
The bottom of slot 7, cutter plate driver 1 is equipped with upper keyway 8, and lower keyway 7 is corresponding with upper keyway 8, is set between upper keyway 8 and lower keyway 7
It is bolted in cutter plate driver 1 after thering is key 4, guide post 5 to be positioned by key 4, and passes through the horizontal phase of key restricted guidance column
To displacement.Lift cylinder 2 is connected with synchronous lifting control system, ensures that lifting process is steady, synchronizes progress.
The outer wall of the bottom shield 3 is equipped with mounting groove 9 corresponding with lift cylinder quantity, the bottom of lift cylinder 2
It is fixedly mounted in mounting groove 9, the telescopic end of lift cylinder 2 is equipped with support plate 10.The support plate 10 is stretched with lift cylinder 2
The cambered surface contact of contracting end, and connected by screw 11, lift cylinder, to the power of cutter plate driver, is made by support plate balanced hoisting oil cylinder
Its jacking action is more steady.
When normal driving, cutter plate driver 1 is connected with bottom shield 3 by connecting bolt 12, the top of lift cylinder 2 and knife
Gap is equipped between dish driving 1, jacking cylinder does not work at this time.When cutterhead digs, remove cutter plate driver 1 and bottom shield 3 it
Between connection bolt 12, lifting oil cylinder 2 synchronizes and is raised above, and unbalance loading is resisted by guide post 5, ensure lifting direction vertically to
On；The lifting of cutter plate driver 1 is more than specified altitude assignment certain distance, the pressure of lifting oil cylinder 2 is kept, in cutter plate driver 1 and bottom shield 3
