Abstract
The utility model discloses a mounting structure of a shaft seat fixed hob cutter for a shield machine, which includes a hob cutter, a tool apron and a cutter head bracket, wherein the tool apron is mounted in the cutter head bracket; a cavity is formed in the tool apron; rhombic grooves used for fixing the hob cutter are formed on upper and lower inner walls of the tool apron; openings are formed on end surfaces of the upper and lower inner walls of the tool apron and communicated with the grooves; and square shaft seats at two ends of the hob cutter are rotated for 45 DEG and fixed on the inner walls of the grooves through wedges. By adopting the mounting structure, the back mounting and constructing can be adopted for the shield machine; the mounting structure is simple; mounting and dismounting are facilitated; the opening of the tool apron is reduced; the rigidity of the tool apron and the hob cutter is improved; and the cutter head design becomes more advantageous as the same tool apron can be used as a pilot cutter box.
Description
Technical field
The utility model relates to a kind of mounting structure of shield machine cutter, relates in particular to the mounting structure of a kind of shield machine with the fixed hobboing cutter of axle bed.
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.How to realize that hobboing cutter not only installed the difficult point that firm but also easy accessibility just becomes shield-tunneling construction.
The utility model content
The purpose of the utility model is to provide the mounting structure of a kind of shield machine with the fixed hobboing cutter of axle bed, can adopt back of the body formula tool changing mode, and mounting structure is simple; Be easy to install, dismantle; Reduce the opening degree of tool rest simultaneously, increased the rigidity of tool rest, guaranteed the rigidity of hobboing cutter; Can also be in same tool rest and the general use of cutter cutter box in advance, increased the optimization property of cutterhead design.
The purpose of the utility model is to realize through following technical scheme:
A kind of shield machine is with the mounting structure of the fixed hobboing cutter of axle bed; Comprise hobboing cutter, tool rest and cutterhead support; Said tool rest is installed in the cutterhead support, and said tool rest inside is cavity, and said tool rest up and down inwall has fixedly hobboing cutter and uses the rhombus groove; Said tool rest inwall end face up and down is provided with opening and is communicated with groove, and the square shaft bearing at said hobboing cutter two ends is fixed on the groove inwall through wedge after rotating 45 °.
Have fixing hole on the said tool rest, place screwed cylinder in the said fixing hole, have unthreaded hole on the said tool rest inwall, said unthreaded hole passes fixing hole.
Said wedge adopts up-narrow and down-wide block structure, and passes through bolton on tool rest, and said bolt passes the cylinder in the tool rest fixing hole.
The beneficial effect of the utility model does, said shield machine is with the mounting structure of the fixed hobboing cutter of axle bed, and its tool rest is the inwall both ends open up and down, can adopt back of the body formula tool changing mode when making shield machine installation/construction; 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.
