Description
Technical field
The present invention relates to the auxiliary support structure of a kind of pair of shield tunneling boring rock tunnel development machine, before in driving
The support of shield shield body and tunnel inner wall is fixed.
Background technology
Double shield tunneling boring rock tunnel development machines（Tunnel Boring Machine, hereinafter referred to as TBM）In China
The tunnel constructions such as water conservancy and hydropower, railway, traffic, city underground engineering, oil-gas pipeline, national defence are quickly grown, using increasingly wide
It is general.In tunnel construction use double-shielded TBM construction technology and equipment, with efficient, high-quality, safety, economy, to rock disturbance
It is small, the advantages of being conducive to environmental protection and reduction labor intensity.
TBM is to integrate broken rock driving, dregs transportation, the integrated equipment of section of jurisdiction supporting.In TBM tunneling process
In, the advance of Rear impact promotes section of jurisdiction to carry out by auxiliary push oil cylinder.In actual tunneling process, sometimes（Such as cross
When standing）Segment assembly is not needed, auxiliary push oil cylinder at this moment can not be leaned on to promote section of jurisdiction dragging Rear impact to advance.In order to solve this
Problem, the implementation of prior art is to support boots by using two stabilizers in anterior shield shield body, by stabilizer support boots and
The anterior shield shield body of boots opposite direction is supportted with stabilizer and the frictional force of tunnel inner wall fixes anterior shield, and oil is promoted mainly using on anterior shield
Cylinder retraction dragging Rear impact advances.Because such a method relies solely on the frictional force of metal and tunnel inner wall, easily skid,
The effect of dragging is bad.
The content of the invention
It is an object of the invention to provide the auxiliary support structure of a kind of pair of shield tunneling boring rock tunnel development machine, to solve
The stabilizer support boots that certainly prior art is present easily skid with tunnel inner wall and cause the problem of dragging effect is bad.
The technical scheme is that：The auxiliary support structure of a kind of pair of shield tunneling boring rock tunnel development machine, it is special
Levy and be, including oil cylinder and support block, being provided with the cylinder base of oil cylinder is used for what is be hinged inside the anterior shield shield body with development machine
Second jointed shaft, the piston rod top of oil cylinder is hinged by the one end side of the first jointed shaft and support block, support block it is another
End near the periphery of anterior shield shield body by the 3rd jointed shaft with being hinged, and the support block can be after the piston rod of oil cylinder stretches out to preceding
Deflected outside the periphery of shield shield body.
A kind of anterior shield component of the auxiliary support structure equipped with described double shield tunneling boring rock tunnel development machines, including
Anterior shield shield body, two stabilizers circumferentially equipped with the 45 ° of central angles in interval on the end face of anterior shield shield body support boots, and its feature exists
In the symmetrical auxiliary support structure equipped with described in two on the opposite semicircle of described two stabilizers support boots.
It is an advantage of the invention that：The structure of Auxiliary support itself causes it to form an anchor with original stabilizer support boots
Fixing structure, so can more be firmly fixed anterior shield, so that promoting mainly supporting advance after oil cylinder is effectively dragged.
Brief description of the drawings
Fig. 1 is the overall structure of the embodiment of the present invention（Non- holding state）Schematic diagram；
Fig. 2 is the structural representation that the present invention shown in Fig. 1 is in holding state embodiment；
Fig. 3 is that the present invention applies the structural representation in anterior shield shield body（Non- holding state）；
Fig. 4 is that the present invention applies the structural representation in anterior shield shield body（Holding state）.
Embodiment
Referring to Fig. 1 and Fig. 2, the auxiliary support structure of a kind of pair of shield tunneling boring rock tunnel development machine of the invention, it is special
Levy and be, including oil cylinder 1 and support block 2, being provided with the cylinder base of oil cylinder 1 is used to cut with scissors inside the anterior shield shield body 6 with development machine
The second jointed shaft 4 connect, the piston rod top of oil cylinder 1 is hinged by the first jointed shaft 3 and the one end side of support block 2, support
The other end of block 2 is by the 3rd jointed shaft 5 with being hinged near the periphery of anterior shield shield body 6.
Referring to Fig. 3 and Fig. 4, a kind of anterior shield component equipped with described auxiliary support structure of the present invention, including anterior shield shield body
6, two stabilizers circumferentially equipped with the 45 ° of central angles in interval on the end face of anterior shield shield body 6 support boots 7, it is characterised in that in institute
The symmetrical auxiliary support structure equipped with described in two on the opposite semicircle for the two stabilizers support boots 7 stated.
The auxiliary support structure of the present invention operationally has two states, and a state is that the piston rod of oil cylinder 1 is not extended out
（As shown in Figure 1）, now support block 2 is within the outer peripheral face 9 of anterior shield shield body 6.Another working condition is, the work of oil cylinder 1
Stopper rod stretches out driving support block 2 and deflected towards the outside of the outer peripheral face 9 of anterior shield shield body 6（As shown in Figure 2）, the side of support block 2 is supported
Firmly（Penetrate）Tunnel inner wall, forms an anchor structure with original two stabilizers support boots 7, so can more firmly consolidate
Surely anterior shield is lived, so that promoting mainly oil cylinder retraction, dragging Rear impact advances.
The features of the present invention has：One is that support block 2 is to spin out to penetrate Dong Bi and prop up, branch when supporting after being dragged after propping up
The stress of bracer 2 is shearing force；Two be that support block 2 penetrates Dong Bi, coordinates with stabilizer support boots 7, forms anchoring.
