Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not paying creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
As shown in Figure 2-5, a kind of rectangular cross section development machine for tunneling underground garage, including anterior shield 5, position
Conveying worm 9, middle shield 6, tail shield 7 and hinged oil cylinder 8 bottom anterior shield, also includes the cross of front end
Flower-shape cutterhead 1 and little cutterhead 2, cross flower-shape cutterhead 1 is driven by main driving 3, and little cutterhead 2 is driven 4 by pair
Driving, described cross flower-shape cutterhead 1 entirety is cross, by two operator 104, two secondary cutter beams 103 of beam
Forming with center fish tail cutter 106, operator beam 104 and secondary cutter beam 103 are mutually perpendicular to, wherein operator beam 104
One end is that rhombus circulus, the other end are fixed on sleeve 101, on operator beam 104, secondary cutter beam 103 all
Being furnished with cutting knife 105, little cutterhead 2 is arranged at the corner of rectangular cross section.
The when that general driving rectangle digging section, excavation rate is low, is likely less than 90%, and main cause is because
The edge of rectangular cross section and dead angle cannot be excavated, and general cutterhead is to do circular turned motion, limited
Trouble is rotated in work space.And in the application, cross flower-shape cutterhead 1 does pendular movement, its amplitude of fluctuation
It is less, it is simple to move in limited space, rhombus circulus 102 can be arranged multiple cutting knife 105,
Improve excavation efficiency, and the when of little cutter rotary, the corner of excavation rectangular cross section, and then make excavation effect
Rate may be up to 97%.
Do the cross flower-shape cutterhead 1 previous plane at the little cutterhead 2 doing gyration of pendular movement, cross
Flower-shape cutterhead 1 and little cutterhead 2 cut rectangle excavated section jointly.
As it is shown in figure 5, cross flower-shape cutterhead 1 does pendulum in anterior shield 5 rectangular area of current size specification
Motion, angle is ± α, and little cutterhead 2 does gyration and the rear plane in the motion of cross flower-shape cutterhead.
The workflow of the present invention is as follows: the anterior shield 5 of current size specification and corresponding middle shield 6, tail shield 7,
Hinged oil cylinder 8 connects, and cross flower-shape cutterhead 1 is driven 4 drive operatings by main driving 3, little cutterhead 2 by pair,
Conveying worm 9 is used to slag tap after having set up earth pressure balance.Now, tunneling section is current size
The rectangular cross section of specification, complete machine uses current hinged oil cylinder 8 tuning.
If the anterior shield of two or more current size specification 5 the most side by side time, it need new middle shield, tail shield,
Hinged oil cylinder is attached thereto, but cross flower-shape cutterhead 1 and little cutterhead 2 are still in respective front dimensions
Operating on anterior shield 5, and two conveying worms 9 are the most independently slagged tap, complete machine uses new hinged oil cylinder tuning.
Rectangle excavated section is formed with geometric ways arrangement by the anterior shield 5 of several current size specifications.Current chi
Anterior shield 5 cross section of very little specification is rectangle, and height dimension is more than width；As shown in Figure 6, advise when current size
The anterior shield of lattice 5 two is transversely arranged；As it is shown in fig. 7, three anterior shields 5 are transversely arranged, as shown in Figure 8,
When six anterior shield horizontal strokes, longitudinal arrangements, may make up the other excavated section of bigger one-level.So, it and corresponding
The middle shield of new size specification, tail shield, just constitute the rectangular cross section development machine of new size specification, can reach weight
Multiple utilization, solves the purpose of resource.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
