Description
Technical field
The utility model relates to a kind of single line trestles with preceding bridge traverse displacement unit, belong to tunnel stack bridge construction technology neck
Domain.
Background technique
With the progress of China's tunnel construction technology, the requirement to the mechanization of inverted arch construction is higher and higher, although at present
There is part of the manufacturer to be capable of providing mechanical single line trestle, but there is trestle work structure complexity, investment is big, heavy, malfunction,
The disadvantages of security performance is not high not can be carried out the popularization of large area.In constructing tunnel, the section-bottom arc of excavation is referred to as
Inverted arch；And in the work progress at tunnel inverted arch position, single line trestle need be set up in inverted arch excavation face, before being connected to tunnel
The excavation face at end and tunnel rear end fill surface channel, fill surface, that is, inverted arch carry out term when concrete construction, inverted arch trestle
In the presence of so that tunnel excavation slags tap to transport not applied by inverted arch into hole with material outward is influenced, inverted arch concrete construction ensure that
It continuously, is simultaneously carried out with tunnel excavation.Since constructing tunnel is not absolute straight line, it is therefore desirable to which inverted arch trestle has traverse displacement unit
Just it is able to achieve the function of automatic inverted arch trestle；And the spacing between two preceding bridges needs to be adjusted, and can facilitate construction.
Utility model content
The purpose of this utility model is to provide a kind of single line trestles with preceding bridge traverse displacement unit, to overcome existing skill
The deficiency of art.
The utility model is technically characterized in that, including trestle main body and preceding bridge, further include traversing inner sleeve, traversing housing and
Traversing oil cylinder, the traversing inner sleeve are connect with trestle main body, and two traversing housings connect with the two preceding bridgings in left and right respectively；
Traversing inner sleeve includes fixed section and linkage section, and fixed section is connect with girder, and traversing housing is set in a left side for linkage section
Right two sides,
Guide groove is arranged in traversing housing, and correspondingly traversing inner sleeve setting limit backing pin, limit backing pin are set among guide groove.It is horizontal
The linkage section for moving inner sleeve further includes oil cylinder otic placode A, traversing housing further include oil cylinder otic placode B, oil cylinder otic placode A and oil cylinder otic placode B it
Between connect traversing oil cylinder.Guide groove is moved along limit backing pin when traversing, guide groove length, that is, traversing housing transverse shifting distance；Limit
Backing pin also enhances traversing inner sleeve end and the intersubjective bonding strength of trestle.
Traversing housing setting limit backing pin；Correspondingly guide groove is arranged in traversing inner sleeve, and limit backing pin is set among guide groove.It is horizontal
It limits backing pin when shifting to move along guide groove, guide groove length, that is, traversing housing transverse shifting distance；Limit backing pin also enhances traversing
Inner sleeve end and the intersubjective bonding strength of trestle.
Connection otic placode is arranged in traversing jacket bottom, and preceding bridge is hinged in connection otic placode.
The utility model has the advantage of limit backing pin strengthens the bonding strength between traversing inner sleeve end and girder.Before
Spacing between bridge is adjustable, is jacked before cooperating wide-angle, it can be achieved that front end is constructed without interference, adaptation range is wider；Before widening
Bridge middle ware is away from achievable large-scale digging machine without interference construction, it can be achieved that tunnel center culvert pipe is pre-buried without interference construction.

Specific embodiment
The preferred embodiment of the utility model is described further with reference to the accompanying drawing, as shown in Fig. 1 to Fig. 8 including stack
Bridge main body 1 and preceding bridge 2, further include traversing inner sleeve 3, traversing housing 4 and traversing oil cylinder 5, the traversing inner sleeve 3 and trestle main body 1
Connection, two traversing housings 4 are connect with the two preceding bridges 2 in left and right respectively；
Traversing inner sleeve 3 includes fixed section 31 and linkage section 32, and fixed section 31 is connect with trestle main body 1, and traversing housing 4 is arranged
In the left and right sides of linkage section 32,
Guide groove 6 is arranged in traversing housing 4, and correspondingly the traversing setting of inner sleeve 3 limit backing pin 7, limit backing pin 7 are set to guide groove 6
Among.The linkage section 31 of traversing inner sleeve 3 further includes oil cylinder otic placode A33, and traversing housing 4 further includes oil cylinder otic placode B41, oil cylinder otic placode
Traversing oil cylinder 5 is connected between A311 and oil cylinder otic placode B41.Guide groove 6 is moved along limit backing pin 7 when traversing, 6 length of guide groove, that is, traversing
The distance of 4 transverse shifting of housing；Limit backing pin 7 also enhances the bonding strength between traversing 3 end of inner sleeve and trestle main body 1.
Connection otic placode 42 is arranged in traversing 4 bottom of housing, and preceding bridge 2 is hinged in connection otic placode 42.
Spacing between preceding bridge 2 is adjustable, is jacked before cooperating wide-angle, it can be achieved that front end is constructed without interference, adaptation range is more
Extensively；2 middle ware of preceding bridge widened away from achievable large-scale digging machine without interference construction, it can be achieved that tunnel center culvert pipe it is pre-buried nothing it is dry
Relate to construction.
Embodiment two, the traversing setting of housing 4 limit backing pin 7, correspondingly guide groove 6 is arranged in traversing inner sleeve 3, and limit backing pin 7 is set
It is placed among guide groove 6.It limits backing pin 7 when traversing to move along guide groove 8,6 length of guide groove, that is, 4 transverse shifting of traversing housing distance；
Limit backing pin 7 also enhances the bonding strength between traversing 3 end of inner sleeve and trestle main body 1.
