Description
Technical field
The utility model is related to shield machine field more particularly to a kind of shield machine tearing cutter fixing devices.
Background technology
Shield method is a kind of construction method in subsurface bored tunnel, and shield machine is the most important of this construction method
Unique construction equipment is one and has multiple functions in the comprehensive equipment of one, it, which has gathered in Tunnel Engineering, excavates, goes out
The function of the whole such as soil, supporting, slip casting, guiding.Include functionally excavation system, main drive system, propulsion system, go out slag system
System, filling system, grease system, hydraulic system, electric control system, automatic guiding system and ventilation, water supply, power supply system,
Harmful gas detecting device etc..Cutter head of shield machine is the core of the capital equipment component and shield machine in shield machine excavation system
Center portion part, its intensity and overall stiffness all directly influence the speed and cost of construction driving, and the maintenance process that is out of order
It is difficult.Cutterhead is a cutting disk body for carrying multiple feed wells, is located at the forefront of shield machine, for cutting the soil body.Cutterhead
Operation principle can simply be compared to be a shaver, soil sandstone is gradually become into fragment during advancing, then is discharged
In " storeroom " after to cutterhead；Shield machine cutter is the main tool of shield tunneling, grasps its correctly selection and user
Method is reasonably arranged on cutterhead, most important for the drivage efficiency, the good economic benefit of creation that improve shield.
Shield can encounter different stratum in the construction process, from mud, clay, layer of sand to soft rock and hard rock.Cutter cutterhead can not possibly
It is machine-made, it is necessary to which personalized designs are carried out according to engineering geological condition.
Shield machine tearing cutter is rotated without the broken rock cutter of rotation with cutterhead, is knife while shield machine is pushed ahead
Tool rotates forward with cutterhead generates the shearing force of axial (along tunnel direction of advance) and radial (cutterhead rotary cutting to the excavation face soil body
Line direction) cutting force, soil cutting in front of excavation face is constantly got off, apply in general to sandy gravel, sand, clay etc. loosely
Layer.Tearing cutter is special-shaped product, cannot as hobboing cutter 360 degree can install.The installation method of existing shield machine tearing cutter
Usually utilize corner block by tool apron it is stuck after, after death installed in girff by bolt lock, if corner block screw hole deviation and
Being drilled to inclined hole all can lead to not install, and in addition as girff is worn, tearing cutter and corner block loosen in girff, reduce work
Make efficiency.
Utility model content
In order to solve the shortcoming present in above-mentioned technology, the utility model provides a kind of shield machine tearing cutter and fixes
Device.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of shield machine tearing cutter is fixed
Device, including knife rest, left tool apron and right tool apron；The knife rest is vertically arranged, and the left tool apron and right tool apron are symmetrically disposed on knife
Frame both sides；Knife rest bottom end is extended to both sides, is sticked in below left tool apron and right tool apron；The left tool apron and right tool apron rail head
In-plane extends, and it is spaced apart on left tool apron and right tool apron be provided through several threaded holes, knife rest bottom end extends
Part is correspondingly arranged threaded hole, and knife rest both ends are bolted connection with left tool apron and right tool apron respectively.
Further, it is welded with shelly cutter head at the top of the knife rest.
Further, the threaded hole of the left tool apron and right tool apron is secured by bolts on cutter head of shield machine.
Further, there are two the knife rests or more than two, it is parallel among left tool apron and right tool apron, passes through a left side
Threaded hole on tool apron and right tool apron is fixed successively.
Further, the screw thread hole number on the left tool apron and right tool apron is more than the quantity of knife rest, left tool apron and right knife
Threaded hole interval immovable support on seat, remaining threaded hole are directly screwed on cutter head of shield machine.
Further, it is connected by reinforcing rib between the adjacent knife rest.
More than two rows of knife rests can be fixed on cutter head of shield machine by the utility model by left tool apron and right tool apron
On, not only facilitate installing and dismounting, overcome the high disadvantage of traditional triangle block structure required precision, and mounting means is secured, solves
Tearing cutter cutter dismounting and change of having determined is difficult, and tearing cutter fixes the problems such as insecure, greatly reduces use cost, reduces manpower
The consumption of material resources.
