Description
Technical field
The utility model relates to underground major diameter excavation work mechanical device, i.e. a kind of underground tunneling engineering mechanical blades disc assembly of major diameter tunneling boring impact grinding hard rock.
Background technology
In highway, railway, subway and mine construction, need in driving major diameter tunnel, underground.Recent two decades comes, driving (shield structure) the machine development of extensive use in tunnel construction is very fast, from the construction originally only adapting to loose (soft) particle geological stratification, existing also at the future development to adaptation tunneling boring hard rock geology (as mine working etc.) and super-large diameter.But at present for the development machine that tunneling boring hard rock geology manufactures, also still rest on the way continuing to use " hobboing cutter breaks rock ".Although " hobboing cutter breaks rock " has successful application under its condition of compatibility, but when being applied to tunneling boring hard rock geological conditions, there is following problem in that then gives prominence to: 1, conventional hobboing cutter applies high-strength compressive stress to the breaking hard rock that rolls with to scope of operation local, broken face, rock stratum is the concentric circles that track repeats, determine its broken rock inefficiency, progress is slow, and efficiency is low; 2, equipment requirement of strength is high, and living load is large; 3, cutter or blade easy to wear, safeguard frequent.
Summary of the invention
In order to overcome current development machine in the construction of tunneling boring hard rock rock layers, inefficiency, progress are slow, efficiency is low and living load large and the shortcoming of cutlery rapid wear, and the utility model provides a kind of underground tunneling engineering mechanical blades disc assembly of major diameter tunneling boring impact grinding hard rock.
The cutter head of this major diameter tunneling boring impact grinding hard rock, comprise machine driving and drilling tool two parts, it is characterized in that, mechanical driving part comprises an outer geosphere, and the inner side of outer geosphere is mutually 120 degree and is provided with three main CD-ROM drive motors; Main CD-ROM drive motor is meshed by the gear on output shaft and transmission gear ring, and transmission gear ring is fixed on the rear of transmission cylinder, and transmission cylinder is arranged in outer geosphere, coaxial with outer geosphere, and transmission cylinder front is fixed with the large cutterhead of revolution; Revolve round the sun on large cutterhead and have 1-3 gear hole, in gear hole, be provided with planetary gear dish, planetary gear dish internal fixtion has three to be mutually the planetary gear internal gear of 120 degree, and planetary gear internal gear and gear hole are meshed, when the large cutterhead that revolves round the sun rotates, drive the revolution of planetary gear dish by planetary gear internal gear; The periphery of planetary gear dish and the engagement of fixing external toothing, fixing external toothing is fixed on outer geosphere; Fixing external toothing is slidably matched with the large cutterhead of revolution, to transmit the longitudinal propulsive force of entirety on outer geosphere; The large cutterhead of revolution is also furnished with 1-3 slag-drip opening.
Tool part comprises jump bit and breaks rock drill bit, sidewall auxiliary shaping hobboing cutter and front auxiliary shaping hobboing cutter.
In the wheel shaft of planetary gear internal gear, be coaxially installed with jump bit break rock drill bit, the rear portion of wheel shaft is provided with jump bit Power Component, and the wheel shaft of planetary gear internal gear is interior empty six square sets, and the outer hexagon drilling rod breaking rock drill bit with jump bit matches, and drives it to rotate.
On the large cutterhead front end face of revolution, be provided with sidewall shaping hobboing cutter, there are pinion and the engagement of fixing external toothing in the installation shaft rear end of sidewall shaping hobboing cutter.
On the large cutterhead front end face of revolution, shaping hobboing cutter in front is installed between planet toothed disc and sidewall shaping hobboing cutter.
At the dynamic swivel joint in jump bit Power Component rear portion of planet toothed disc, power swivel rotates distribution joint by service line, dynamic rotation distribution joint and total output and is connected, dynamic rotation distribution joint and total output rotate distribution joint, are separately fixed on planetary gear dish and the large cutterhead of revolution by support.
