Abstract
The utility model discloses a kind of liftable shield machine brackets, shield machine bracket is that each road crossbeam that will be mutually parallel passes through longitudinally connected composition chassis, it is laid with longeron on chassis, is laid with longitudinal rail in the top surface of longeron, bearing is formed to shield machine by longitudinal rail；It is characterized in that：Be arranged shield machine bracket be can climbing structure, jacking position is located at the shaped steel bottom of longitudinal rail, and the jacking force position in the rail of per pass longitudinal direction is spaced apart at least 3 points.The utility model has ensured that shield machine shadow head process is smooth reliable, shortens construction period, it is ensured that shield machine jacks process safety.
Description
Technical field
The utility model is related to Shield Construction Technique field, more specifically a kind of shield machine bracket.
Background technology
Shield-tunneling construction has become a kind of construction technology of maturation in engineering field, and is widely used in subway construction；
Shield machine shadow head refers to：The case where separate unit shield machine tunneling construction is put into for section double track tunnel, in single line
It is reversed end for end reversely to tunnel after tunnel piercing completion, shield machine perforation.With transition technics comparing, u-turn technique can save shield machine
Transition transportation cost shortens the turn-round time, and reduction carries out dismantling flow to shield machine main body, the separation of corollary equipment in the completed
Afterwards shield machine is integrally reversed end for end to operate, be had substantial degradation to relevant technical complexity, therefore obtains a degree of application.
Since shield machine shadow head process is to carry out in height in a limited space, it is therefore desirable to carry out height to shield machine
Adjustment, it is often the case that：Bracket absolute altitude when bracket absolute altitude of the shield machine when receiving is than shield machine shadow head is high, because
This needs to carry out padded when shield machine receives in shield machine bracket bottom；After shield machine finishes receiving, then by the pad of bottom
Height is detached, and carries out shield machine in turnabout period operation again later；And after the completion of u-turn, and need after jacking shield machine bracket
It carries out again padded.In the prior art, it is by welding counter-force with shield shell on shield machine for this kind of jacking and padded adjustment
Component is implemented to jack using the hydraulic jack of four 200t to shield machine；But since shield body kind is big, weight height exists
360t, in practice of construction, four hydraulic jack force positions are few, and local pressure is excessive, and whole discontinuity may all be led
Reaction component desoldering is caused, causes shield machine jacking process to have some setbacks, cannot smoothly realize jacking, directly affect the duration.
Utility model content
The utility model is to provide a kind of liftable shield machine support to avoid above-mentioned deficiency of the prior art
Frame shortens construction period, it is ensured that shield machine jacks process safety to ensure that shield machine shadow head process is smooth reliable.
The utility model is to solve technical problem to adopt the following technical scheme that：
The liftable shield machine bracket of the utility model, the shield machine bracket are that each road crossbeam that will be mutually parallel passes through
Longitudinally connected composition chassis, longeron is laid on the chassis, longitudinal rail is laid in the top surface of the longeron, by the longitudinal direction
Rail forms shield machine and supports；It is structurally characterized in that：Be arranged the shield machine bracket be can climbing structure, jacking position be located at
The shaped steel bottom of the longitudinal direction rail, the jacking force position in the rail of per pass longitudinal direction are spaced apart at least 3 points.
The design feature of the liftable shield machine bracket of the utility model is lain also in：Jacking in the rail of the per pass longitudinal direction
Force position is distributed according to the spacing of corresponding position upper beam.
The design feature of the liftable shield machine bracket of the utility model is lain also in：Longitudinal rail at the jacking position
Shaped steel bottom welding 2cm thickness strengthening steel slab, to prevent whole stress deformation.
The design feature of the liftable shield machine bracket of the utility model is lain also in：Setting is used in each jacking part
Realize that the jack of jacking uses the hydraulic jack of 40t.
Compared with the prior art, the utility model has the beneficial effect that：
1, the utility model overall structure is secured, for the shield machine of conventional 360t, can divide in entire shield machine bracket
The hydraulic jack of 14 40t of cloth realizes the light jacking of 360t shield machines, and load rate 65%, process is smooth reliable, has
Effect ensure that smooth implementation that is padded and detaching process.
2, the utility model to finish receiving in shield machine or after the completion of shield machine in turnabout period, eliminates jacking reaction component
Processing and welding, effectively shorten construction period, it is ensured that shield machine jacks process safety.
Description of the drawings
Fig. 1 is the utility model schematic view of facade structure；
Fig. 2 is the utility model planar structure schematic diagram；
Figure label：1 crossbeam, 2 longerons, 3 longitudinal rail, 4 shield machines, 5 strengthening steel slabs, 6 jack, 7 rail pressing plates.
Specific implementation mode
Referring to Fig. 1 and Fig. 2, the shield machine bracket in the present embodiment is that each road crossbeam 1 that will be mutually parallel is connected by longitudinal
Composition chassis is connect, longeron 2 is laid on chassis, longitudinal rail 3 is laid in the top surface of longeron 2, using rail pressing plate 7 to longitudinal steel
Rail 3 is fixed, and bearing is formed to shield machine 4 by longitudinal rail 3；It is that can jack knot that shield machine bracket is arranged in the present embodiment
Structure, jacking position are located at the shaped steel bottom of longitudinal rail 3, the jacking force position in per pass longitudinal direction rail 3 be spaced apart to
It is 3 points few, it can be distributed according to the spacing of corresponding position upper beam 1.
In order to ensure that overall structure is secured, stress deformation is prevented, is welded in the shaped steel bottom of longitudinal rail at jacking position
There is the strengthening steel slab 5 of 2cm thickness.
Shown in Fig. 1 and Fig. 2, it is directed to the shield machine 4 of routine 360t in the present embodiment, is shared in the chassis of shield machine bracket
The jack 6 of seven 40t is distributed with corresponding to per pass longeron for eight crossbeams 1, amounts to the jack 6 using 14 40t, lotus
Load rate is 65%, and 360t shield machines is enable easily to jack.
