Description
Technical field
The utility model relates to a kind of shield machine, relates in particular to a kind of hard rock cutter head of shield machine structure.
Background technology
Large-scale shield machine is mainly used in the constructing tunnel, and the operating mode of shield machine construction is generally comparatively abominable, and as the cutter head of one of shield machine key equipment, its structure not only will directly influence the performance and the efficient of shield machine, also can influence the complexity that cutterhead is made.The type of the cutter of installing on the cutter head of shield machine, position all are custom-designed according to geological condition, because the hobboing cutter cutter box that generally is installed on the cutterhead is a rectangular configuration; Make that not only large-scale shield machine processing welding capacity is big, cost is high; But also be prone to cause precision inaccurate, also have cylindrical hobboing cutter cutter box is installed on cutterhead, but fixed form adopts bolt that hobboing cutter directly is connected on the hobboing cutter cutter box; Under abominable working condition; Reliability is bad, and hobboing cutter is changed relatively difficulty midway, and abnormally dangerous.
The utility model content
The purpose of the utility model is to provide a kind of hard rock cutter head of shield machine structure, and that this structure is installed is simple, the hobboing cutter on it is easy to dismounting, has solved that shield machine cutter box processing welding capacity is big, cost is high, but also is prone to the problem that causes precision inaccurate.
The purpose of the utility model realizes through following technical scheme:
A kind of hard rock cutter head of shield machine structure; Comprise that cutterhead, said cutterhead are provided with the tool rest that is welded with drum type brake in cutterhead support, the said cutterhead support; Be placed with the column type hobboing cutter in the said tool rest; Have unthreaded hole on the cutter shaft fixed bearing of said column type hobboing cutter, have the fixedly screwed hole of cutter shaft fixed bearing on the said tool rest, cutter shaft fixed bearing and tool rest are linked through oblique chock and bolt; Have chamfered groove in the said tool rest; The location that cooperatively interacts, two sides that the cutter shaft of said column type hobboing cutter and tool rest are adjacent; Another side of the cutter shaft of said column type hobboing cutter contacts with a side of wedge; Two sides in addition of said wedge contact with chamfered groove, and said wedge links through the screwed cylinder of placing in the cylindrical hole in bolt and the tool rest, and cutter shaft is pressed abd fixed in the tool rest.
Further, the centre of said tool rest and tool rest is provided with the reinforcement gusset.
The beneficial effect of the utility model is: because inwall is offered chamfered groove about being employed in its tool rest, make shield machine install and can adopt back of the body formula tool changing mode (at the back of shield machine dish replacing hobboing cutter) when perhaps hobboing cutter is changed in construction; Owing to adopt wedge fixed cylinder formula cutter shaft, can make hobboing cutter fixing more firm, this mounting means is not only firm, and has avoided a large amount of cost that welding brought height, the problem that precision is inaccurate.
