The shortcomings of security performance is not high, it is impossible to carry 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, inverted arch trestle need be set up in inverted arch excavation face, before connecting tunnel
The excavation face at end and tunnel rear end fill surface passage, fill surface are term when inverted arch carries out concrete construction, inverted arch trestle
In the presence of tunnel excavation outwards to slag tap to transport not applied by inverted arch into hole with material to be influenceed, inverted arch concrete construction ensure that
Continuously carried out simultaneously with tunnel excavation.Because constructing tunnel is not absolute straight line, it is therefore desirable to which inverted arch trestle possesses traverse displacement unit
The function of automatic inverted arch trestle could be realized.
Utility model content
The purpose of this utility model is to provide a kind of traverse displacement unit of new type auto inverted arch trestle, to overcome existing skill
The deficiency of art.
The utility model is achieved through the following technical solutions, including preceding access bridge, main bridge, rear access bridge, preceding access bridge and rear access bridge
It is hinged respectively with main bridge rear and front end, host bridge is two symmetrical box girder constructions, and main pars basilaris pontis is provided with transverse-moving mechanism
And the running gear of vertical folding and unfolding, transverse-moving mechanism replace load-bearing with running gear；
Transverse-moving mechanism includes crossbeam and traversing oil cylinder, and crossbeam is arranged on any one box beam bottom by traversing oil cylinder.
By realizing the transverse shifting of transverse-moving mechanism, so as to realize the traversing of main bridge.
By being articulated and connected, the other end is hinged the otic placode of traversing oil cylinder one end and box beam with crossbeam.
The transverse-moving mechanism includes transverse-moving mechanism at the two of front and rear setting.
The running gear is provided with corresponding with transverse-moving mechanism two.
The utility model has the advantages of simple in construction, cost is cheap, easy to use, reliability is high, widely applicable.Can be real
Existing modularization, each part can assemble in factory, convenient transportation, and on-site consolidation is simple.
