Description

One kind being suitable for super-large diameter hard rock mole cutterhead
Technical field
The present invention relates to constructing tunnel equipment, particularly relate to a kind of suitable for super-large diameter hard rock mole cutterhead.
Background technique
Shield method gradually becomes most efficient tunnel excavation engineering method, and cutterhead is the important component of development machine.The country is to hard The research emphasis of rock development machine (TBM) cutterhead is in the side such as solid cutter force analysis, cutter layout, knife disc tool life search Face has made great progress, while also harvesting many achievements.
Currently, the cutterhead that tunneling boring hard rock mole uses largely is board wheel structure.The digging process of cutterhead It is the hard rock hob of cutterhead surface layout and the process of rock stratum interaction, existing major diameter hard rock mole cutter diameter is done To 9 meter levels, but some engineering projects have bigger demand to tunnel diameter, need to accomplish the super-large diameter suitable for 15 meter levels Hard rock mole design.Therefore, the design of development machine cutterhead must be carried out according to the formation geology condition " cutting the garment according to the figure " in tunnel Targetedly design.
For super-large diameter long distance tunnel, building site, traffic congestion, dysdipsia status, while also day can be relieved Benefit becomes the important channel of the exploitation of urban underground space.Major diameter development machine cutterhead used at present is using hobboing cutter spiral Line layout is rotated by cutterhead and hobboing cutter rotation extruding rock stratum is driven to realize broken rock.Since excavated section makes greatly: 1. cutterheads are born Full payload it is excessive, unbalanced moments is excessive and cutterhead is caused to deform;2. cutterhead rotates in tunneling process, edge hobboing cutter linear velocity Excessive, serious wear, cutter life is short.
Summary of the invention
The present invention proposes that one kind is suitable for super-large diameter hard rock mole cutterhead, can overcome existing hard rock mole, especially It is that super-large diameter development machine cutterhead digging diameter is restricted, when reply ground consisting of hard rock excavates section super large situation, the diameter of cutterhead To out-of-balance force, tilting moment is big, cutter life is short the disadvantages of.Two-stage cutterhead can effectively be distributed to rock break load respectively Grade cutterhead, while cutterhead rigidity is improved, cutterhead stress concentrations are avoided, the eccentric load of cutterhead is effectively reduced.Needle Different rock-layers geology operating condition is installed advanced by adjusting level-one cutterhead, second level knife disc tool distribution form in second level cutterhead Outstanding cutter broken rock reaches the one-pass molding in super-large diameter tunnel so that classification driving, combination driving integrally may be implemented in cutterhead. Promote super-large diameter hard rock mole drivage efficiency and driving quality.
The technical scheme of the present invention is realized as follows: a kind of be suitable for super-large diameter hard rock mole cutterhead, including one Grade cutter head assembly and second level cutter head assembly, level-one cutter head assembly and second level cutter head assembly are equipped with axial propulsion device, level-one knife Disk component includes level-one cutterhead and level-one cutter, and second level cutter head assembly includes second level cutterhead and second level cutter, level-one cutterhead it is outer Diameter is less than the internal diameter of second level cutterhead, the second level cutterhead be it is round table-like, second level cutter includes outstanding cutter, and outstanding cutter is ladder-like sets It sets on second level cutterhead.
The outstanding cutter is equipped with several layers, and the outstanding cutter of several layers section is stepped to be arranged on second level cutterhead.
The level-one cutterhead is board wheel, and level-one cutter includes the central hob being located on level-one cutterhead, positive rolling Knife and side hobboing cutter, level-one cutterhead are equipped with level-one slag notch.
The central hob is located at the center of level-one cutterhead, and side hobboing cutter is located at the edge of level-one cutterhead, and positive hobboing cutter is located at Between central hob and side hobboing cutter, central hob and positive hobboing cutter are installed perpendicular to cutterhead face, and side hobboing cutter favours the installation of cutterhead face.
The second level cutter includes the edge doctor on second level cutterhead, and second level cutterhead is equipped with second level slag notch.
The edge doctor is located at the edge of second level cutterhead, and outstanding cutter favours the installation of cutterhead face.
The level-one cutterhead is panel type.
The second level cutterhead is plate spoke.
Compared with prior art, the beneficial effects of the present invention are: solving seriously puzzlement hard rock tunnel construction for a long time Cutterhead geological adaptability is poor, the problems such as super-large diameter drivage efficiency is low, knife disc tool limitation cutterhead digging diameter, according to geology Adaptive Theory, level-one cutterhead use hard rock hob allocation plan, and second level cutterhead is using outstanding cutter matching as broken rock cutter Scheme is set, so that two-stage cutterhead being capable of separately adjustable driving speed in tunneling process.Due to seperated using two-stage cutter disc system Formula design, substantially increases the geological adaptability of super-large-diameter shield cutterhead, improves Acceptable life, the pick of knife disc tool Into efficiency and economy.
