Description
Technical field
The present invention relates to the cutter head structure of shield machine, particularly a kind of hard rock cutter head of shield machine structure that the fixed hobboing cutter of square axle bed is installed.
Background technology
Shield machine is mainly used in the constructing tunnel, and the operating mode of shield-tunneling construction is generally comparatively abominable, and the wearing and tearing of cutter are inevitable; Often need to change cutter in the work progress,, cause changing cutter and have bigger risk in the cutter head of shield machine front still owing to the restriction of shield machine working environment and operating principle; Because the structure of hobboing cutter and the restriction of position, the hobboing cutter tool rest generally is welded on the cutter head of shield machine, makes that the replacing hobboing cutter is all very difficult before and after cutterhead; Simultaneously; Because operating mode is changeable, in the shield machine tunneling process, need hobboing cutter be replaced with cutter in advance sometimes; Change so to get up to be difficult to, how to realize that therefore hobboing cutter not only installed the difficult point that firm but also easy accessibility just becomes shield-tunneling construction.
Summary of the invention
The purpose of this invention is to provide a kind of hard rock cutter head of shield machine structure that the fixed hobboing cutter of square axle bed is installed, solve the problem that the difficult installation of hobboing cutter is firm and dismounting is inconvenient on the cutterhead.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of hard rock cutter head of shield machine structure that the fixed hobboing cutter of square axle bed is installed; Comprise hobboing cutter, tool rest and cutterhead support; Said tool rest welded and installed is between corresponding a pair of cutterhead support; Tool rest up and down inwall all has the rhombus groove that fixing hobboing cutter is used, and tool rest up and down the inwall end face all be provided with the opening that is communicated with groove, the square shaft bearing at said hobboing cutter two ends is fixed on the groove inwall through wedge after rotating 45 °.
As a preferred version, have fixing hole on the said tool rest, all have the unthreaded hole that passes fixing hole on the tool rest inwall; Said wedge adopts up-narrow and down-wide rectangular configuration; Said square axle bed and groove inwall are close to, and in the middle of the rear portion is fixed on wedge groove inwall and square axle bed side, in fixing hole, insert threaded cylinder; Bolt passes wedge and threaded cylinder through being threaded, and wedge is fastening.
As further preferred version, said tool rest can be single chamber, two-chamber and four chamber tool rests, and said hobboing cutter can be single-blade and twolip hobboing cutter.
The present invention is through adopting two kinds of fixed hobboing cutters of square axle bed; Be twolip hobboing cutter and single-blade hobboing cutter; Be installed in hobboing cutter in three kinds of multi-form hobboing cutter tool rests many, all tool rests all at inwall both ends open up and down, can adopt back of the body formula tool changing mode when making shield machine installation/construction; All adopt wedge and bolton, can make axle bed fixing more firm; Use threaded small column, when changing cutter, can change together, be convenient to install with bolt; The square shaft bearing at hobboing cutter two ends is fixed on the groove inwall through wedge after rotating 45 °, has reduced the opening degree of tool rest, has increased the rigidity of tool rest, has guaranteed the rigidity of hobboing cutter simultaneously again; Simultaneously can also be in same tool rest and the general use of cutter cutter box in advance, increased the optimization property of cutterhead design.
