Description
Technical field
The utility model relates to a kind of composite shield stabilizers, mainly as the stabilizer of balancing earth-pressure shielding machine.
Background technique
With the development that present urban inner is built, the construction of previous single ground environment will be to complicated, composite bottom layer hair
Exhibition, there are backfill, rock, texture stratum etc. in city stratum, while cannot destroy to the building above construction tunnel, some people
Mouth also compares comparatively dense.Therefore, when the section of composite bottom layer is constructed, it is desirable to which equipment once completes section construction working, reduces
Excavating equipment (balancing earth-pressure shielding machine, abbreviation EPB) residence time in hole reduces the risk that ground generates sedimentation.This is just
It is required that equipment is able to satisfy lithostratigraphy, and it is able to satisfy the requirement of texture stratum construction.In lithostratigraphy is constructed, front knife
The tunnel diameter that disc spins are excavated is bigger than the diameter of device Host part, is easy in the equipment course of work because of unbalance stress
Cause the rolling of device Host part or vibration by a relatively large margin, to generate latent dangerous factor to equipment and construction safety.Soil
Press balance shield machine (abbreviation EPB) for partial section there are tunneling boring rock stratum, need higher rotation speed, can increase host vibration and
The trend of rolling.The anterior shield upper half is arranged symmetrically two groups of stabilizers, and the vibration that host transmits can be absorbed in the oil cylinder for supportting boots, to knife
Disc vibration forms semi-rigid constraint, and shield body can be effectively reduced and roll probability.The structure of existing stabilizer is resistance to by oil cylinder pushing
Mill support boots are withstood on rock wall with certain pressure, stablize host machine part by the reaction force to hole wall.The structure compresses
The pressure of hole wall is not easily controlled, and because the hole wall that cutterhead rotation is excavated out is not the plane of rule, is also easy to produce male and fomale(M&F).Support boots are stretched
Length out is certain, therefore pressure and frictional force size variation are larger.
Summary of the invention
The purpose of this utility model is just to provide a kind of composite shield stabilizer, to solve compression of the existing technology
The pressure of hole wall is not easily controlled, and because the hole wall that cutterhead rotation is excavated out is not the plane of rule, is also easy to produce male and fomale(M&F).Support boots are stretched
Length out is certain, therefore pressure and the larger problem of frictional force size variation.
To achieve the above object, technical solution adopted in the utility model is: a kind of composite shield stabilizer, including

The periphery of bracket is slidably and sealingly installed inside the shell, passes through the discoidal hobboing cutter of axis rotational support one in the mouth of U-bracket；
Top cover is housed at the top of the shell, hobboing cutter corresponding with hobboing cutter hole is equipped on the top cover.
The hobboing cutter is circular ring shape, is equipped with columnar hobboing cutter installation set in its inner shaft, passes through in the hobboing cutter installation set
Bearing is mounted on the axis；Sealing mechanism is housed at the both ends of the bearing.
It is equipped with outward flange in one end of the hobboing cutter installation set, annular groove is equipped in the outer peripheral surface of the other end, at this
The hobboing cutter is installed, and the circlip by being stuck in the annular groove fixes hobboing cutter between annular groove and the outward flange.
At least provided with two seals ring between the periphery and outer casing inner wall of the U-bracket.
The hobboing cutter is identical as the hobboing cutter on cutter head of shield machine.
The sealing mechanism includes O-shaped rubber ring, support ring and sealing cover, two support rings coaxially overlapped
It is respectively provided with an O-shaped rubber ring in the groove of periphery, sealing cover is equipped in the outside of support ring, on the inside of the outer rim of the sealing cover
Groove equipped with that support ring for accommodating outside；The outer peripheral surface of one O-shaped rubber ring of inside and hobboing cutter installation set
Inner peripheral surface offsets, and the outer peripheral surface of an O-shaped rubber ring in outside and the inner peripheral surface of the groove on the inside of the outer rim of sealing cover offset.
The utility model has the advantages that: the hobboing cutter of stabilizer is pressed into the wall of hole by oil cylinder, because there is part edges insertion
Hole wall thus can use the depth of blade insertion hole wall, guarantees to contact hole wall always, and provide reaction force, maintains master
Machine is stablized.The hobboing cutter of stabilizer is rotationally advancing along hole wall in turn before can following equipment simultaneously, is reduced and the generation of hole wall friction
Resistance reduces the resistance that equipment is advanced.When replacement or reparation, the hobboing cutter that can borrow cutterhead is interchangeable, and improves spare part
Exchange versatility.
