Abstract
The utility model is related to the traverse displacement units that a kind of big-elevation promotes bridge before trestle, belong to tunnel inverted arch technical field of construction, including connection trestle main body, preceding bridge and stroke oil cylinder, further include the traverse displacement unit for being horizontally installed on trestle body front end, preceding bridge is hinged with traverse displacement unit, before stroke oil cylinder is arranged between the bottom of bridge and traverse displacement unit；Traverse displacement unit includes inner sleeve, housing and traversing oil cylinder, and the both ends of inner sleeve be connecteds with trestle main body, housing be nested in it is interior put on, the cylinder barrel of traversing oil cylinder is fixed on the upper of inner sleeve, and the piston rod fixation of traversing oil cylinder is on the coat.The advantage is that possessing the traverse moving function of bridge before big jacking angle and left and right, accommodation is wider；The spacing between bridge, cooperation wide-angle jacking before left and right can be adjusted and realize that front end is constructed without interference；The preceding bridge spacing particularly widened can realize large-scale digging machine without interference construction, it can be achieved that tunnel center culvert pipe it is pre-buried without interference construct.
Description
Technical field
The utility model is related to the traverse displacement units that a kind of big-elevation promotes bridge before trestle, belong to tunnel inverted arch construction technology neck
Domain.
Background technology
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
In, inverted arch trestle need be set up in inverted arch excavation face, the excavation face of tunnel front end and tunnel rear end fill surface passage is connected, fills out
Fill term when face i.e. inverted arch carries out concrete construction, the presence of inverted arch trestle causes tunnel excavation outwards to slag tap with material to hole
It is interior to transport the influence applied from inverted arch, ensure that inverted arch concrete construction with tunnel excavation continuously, be carried out at the same time.But it applies at present
It is insufficient below trestle generally existing used in work：The preceding bridge of the prior art is directly promoted by oil cylinder, and shortcoming is oil cylinder
Stroke is limited, causes promotion angle inadequate.
Utility model content
It is existing so as to overcome the purpose of this utility model is to provide the traverse displacement unit that a kind of big-elevation promotes bridge before trestle
The deficiency of technology.
The utility model is achieved through the following technical solutions, and including connection trestle main body, preceding bridge and stroke oil cylinder, is further included
The traverse displacement unit of trestle body front end is horizontally installed on, preceding bridge is hinged with traverse displacement unit, the bottom of bridge before stroke oil cylinder is arranged on
Between traverse displacement unit；Traverse displacement unit includes inner sleeve, housing and traversing oil cylinder, and the both ends of inner sleeve are connected with trestle main body, housing
It is put in being nested in, the cylinder barrel of traversing oil cylinder is fixed on the upper of inner sleeve, and the piston rod of traversing oil cylinder is fixed on the coat.
Before stroke oil cylinder is arranged between the bottom of bridge and housing.
Preceding bridge and housing hinge connection.
The utility model has the advantage of possess the traverse moving function of bridge before big jacking angle and left and right, accommodation is more
Extensively；The spacing between bridge, cooperation wide-angle jacking before left and right can be adjusted and realize that front end is constructed without interference；Before particularly widening
Bridge spacing can realize large-scale digging machine without interference construction, it can be achieved that tunnel center culvert pipe it is pre-buried without interference construct.
Description of the drawings
Fig. 1 is the utility model technology schematic diagram.
Fig. 2 jacks view for preceding bridge.
Fig. 3 is bottom view.
Fig. 4 widens operation schematic diagram for preceding bridge.
Specific embodiment
It is described further below by the preferred embodiment of 1 to 4 pair of the utility model of attached drawing,
Including connection trestle main body 1, preceding bridge 11 and stroke oil cylinder 2, the horizontal stroke for being horizontally installed on 1 front end of trestle main body is further included
Moving device 3, preceding bridge 11 and traverse displacement unit 3 are hinged, stroke oil cylinder 2 be arranged on before between the bottom of bridge 11 and traverse displacement unit 3；
Traverse displacement unit 3 includes inner sleeve 31, housing 32 and traversing oil cylinder 33, and the both ends of inner sleeve 31 are connected with trestle main body 1, outside
Set 32 is nested in inner sleeve 31, and the cylinder barrel 331 of traversing oil cylinder 33 is fixed on the upper of inner sleeve 31, the piston rod 332 of traversing oil cylinder 33
It is fixed on housing 32.
Stroke oil cylinder 2 be arranged on before between the bottom of bridge 11 and housing 32.When preceding bridge 11 jacks, stroke oil cylinder 2 works, ginseng
See attached drawing 2, possess big jacking angle.
Preceding bridge 11 and 32 hinge connection of housing.
During preceding 11 traversing work of bridge, referring to attached drawing 4, traversing oil cylinder 33 drives two Slideslips of the housing 32 to inner sleeve 31, i.e.,
Preceding bridge 11, the stroke oil cylinder 2 opposite inner sleeve 31 together with housing 32 to two Slideslips, so as to adjust the spacing of bridge before left and right 11, add
Wide spacing can realize large-scale digging machine without interference construction, it can be achieved that tunnel center culvert pipe it is pre-buried without interference construct.
