Domestic research and the patent still not having similar inclined shaft engineering open cut lining cutting section TBM main frame dropping method at present.
Summary of the invention
The object of the invention is, in order to solve main frame fall problem in the stepping of TBM construction coal mine inclined shaft shield structure, origination process, to provide a kind of and solve inclined shaft open cut lining cutting section TBM main frame dropping method, adopt the invention process simple and convenient, safe and reliable.
For reaching above object, solution of the present invention is: a kind of inclined shaft open cut lining cutting section TBM main frame dropping method, carries out according to the following step:
(1) on main frame shield body, Fang Niu mechanism, oil cylinder supporting seat and anti-fall counter-force supporting bracket is welded;
(2) in place on TBM starts district's base plate steel plate and welding supports main frame lowering mechanism, at portal position welding counterforce device; Support main frame lowering mechanism comprise the bottom bearing diagonal block that is arranged on the multiple case beams bottom TBM host cradle, the top bearing diagonal block being arranged on case back portion, mounting base steel plate and support for the multilayer circle of support box beam;
(3) weight beetle haulage system is in-orbit utilized, by TBM main frame pushing tow to assigned address;
(4) jacking cylinder location weld with oil cylinder supporting seat, carry out speed and synchronism is debugged, multilayer is installed bottom jacking cylinder and justifies support;
(5) at the uniform velocity jacking main frame, extracts the heavy rail being used for main frame stepping out, slowly falls main frame, the complete pressure release of oil cylinder after TBM host cradle bottom surface arrives case beam, by bracket and case beam and the bearing diagonal block welding of case back portion;
(6) remove the first floor bracing members of support top oil-lifting jar, jacking cylinder jack-up TBM main frame, remove the first floor Rod Bracing supporting main frame lowering mechanism;
(7) alternately remove according to above method all circles supporting main frame lowering mechanism to support, and cut off bottom case beam and bottom bearing diagonal block on base plate steel plate, main frame falls, and removes last one deck and supports for the circle of support cylinder;
(8) jacking main frame, cut off case beam, the TBM bracket that makes to start is directly in place at base plate steel plate, cuts off the oil cylinder supporting seat be welded on main frame.
Install between above-mentioned case beam and support.
Install between above-mentioned case beam and base plate steel plate and support.
The present invention has following advantage and good effect:
1, present invention efficiently solves in small space, bottom board slope >=6 °, the TBM main frame of weight > 500t, the demand in place of distance of fall > 1.3m.
2, the present invention arranges Fang Niu mechanism and anti-fall counter-force bracing frame, can effectively prevent and retrain the dislocation that TBM main frame occurs in stepping and falls into position process, reduces construction risk, plays antitorque and anti-fall effect, within the maximum restriction 10mm of constraint dislocation.
3, the support main frame lowering mechanism in the present invention and support top oil-lifting jar mechanism adopt block design, greatly reduce difficulty of construction, implement simple and convenient, safety of structure and reliability high.
Accompanying drawing illustrates:
Fig. 1 is schematic cross section of the present invention;
Fig. 2 is vertical section of the present invention schematic diagram.
In figure: 1-TBM main frame, 2-Fang Niu mechanism, the anti-fall counter-force supporting mechanism of 3-, 4-support top oil-lifting jar, 5-oil cylinder supporting seat, 6-host cradle, 7-case beam, 8-support bearing diagonal, 13-base plate steel plate at the bottom of the support of main frame fall system circle, the support of 9-support cylinder jack-up system circle, 10-lining cutting section agent structure, 11-top bearing diagonal, 12-.
Detailed description of the invention:
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
