Abstract
The invention discloses a mounting structure of an axle base fixed type hobbing cutter for a shield machine. The mounting mechanism comprises a hobbing cutter, a cutter holder and a cutter head bracket, wherein the cutter holder is mounted in the cutter head bracket; a cavity is formed in the cutter holder; the upper and lower inner walls of the cutter holder are provided with rhombic grooves for fixing the hobbing cutter; the end surfaces of the upper and lower inner walls of the cutter holder are provided with openings which are communicated with the grooves; and the square axle bases at the two ends of the hobbing cutter are rotated for 45 degrees and fixed on the inner walls of the grooves through wedge blocks. Through the mounting structure, the mounting/construction of the shield machine can be performed in a back mode, and the mounting structure is simple and easy to mount and dismantle; meanwhile, the openness of the cutter holder is reduced, and the rigidity of the cutter holder is enhanced, thus the rigidity of the hobbing cutter is guaranteed; and moreover, the mounting structure can be generally used with a prior cutter box in the same cutter holder, and the cutter head design is optimized.
Description
Technical field
The present invention relates to a kind of mounting structure of shield machine cutter, relate 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, the operating mode of shield-tunneling construction is generally comparatively abominable, the wearing and tearing of cutter are inevitable, often need to change cutter in the work progress, but because the restriction of shield machine working environment and operating principle, cause changing cutter and have bigger risk in the cutter head of shield machine front, 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, make 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 sometimes hobboing cutter is replaced with cutter in advance.How to realize that hobboing cutter not only installed the difficult point that firm but also easy accessibility just becomes shield-tunneling construction.
Summary of the invention
The object of the present invention 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, 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 of cutterhead design.
The objective of the invention is to be achieved through the following technical solutions:
A kind of shield machine mounting structure of the fixed hobboing cutter of axle bed, comprise hobboing cutter, tool rest and cutterhead support, described tool rest is installed in the cutterhead support, described tool rest inside is cavity, described tool rest inwall up and down has fixedly hobboing cutter rhombus groove, described tool rest inwall end face up and down is provided with opening and is communicated with groove, and the square shaft bearing at described hobboing cutter two ends is fixed on the groove inwall by wedge after rotating 45 °.
Have fixing hole on the described tool rest, place screwed cylinder in the described fixing hole, have unthreaded hole on the described tool rest inwall, described unthreaded hole passes fixing hole.
Described wedge adopts up-narrow and down-wide block structure, and by bolton on tool rest, described bolt passes the cylinder in the tool rest fixing hole.
Beneficial effect of the present invention is, described 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 by 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 of cutterhead design.
