Description
Technical field
The present invention relates to the movable support mechanism of a kind of box type girder base-supporting trestle, belong to tunnel inverted arch construction bridge technical field.
Background technology
When constructing tunnel, the section-bottom arc of excavation is referred to as inverted arch；And in the work progress at inverted arch position, tunnel, inverted arch trestle need be set up in inverted arch excavation face, the excavation face of connection front end, tunnel and filling face, rear end, tunnel passage, filling face i.e. inverted arch carries out term during concrete construction, the existence of inverted arch trestle makes tunnel excavation outwards slag tap and material transports not executed by inverted arch in hole and affected, it is ensured that inverted arch concrete construction and tunnel excavation continuously, carry out simultaneously.For meeting the light-gauge tunnel of single line, it is desirable to there is more compact structure, meet the trestle requirement of different spans；Difficulty of construction in single-track tunnel is bigger, it is desirable to the automaticity of trestle is higher, and the miscellaneous function having is more；And existing trestle work structure cannot meet the light-gauge constructing tunnel of single line.But the trestle used in construction generally has the disadvantage that in the prior art at present, and the application of hydraulic jack is quite varied, but oil cylinder can not bear radial forces.In the technology of traditional two-stage oil cylinder, it is desirable to oil cylinder installing space size when shrinking is shorter, but requires that the impulse stroke of oil cylinder is longer, thus the use of multi-stage oil cylinder gets more and more.Multi-stage oil cylinder has longer stroke to realize mechanical action at axial elongation, but oil cylinder in use can not be by active force radially, and particularly when oil cylinder extends, oil cylinder can not bear radial force completely.Easily damaging oil cylinder and oil cylinder supporting leg, the purpose of the present invention is for realizing oil cylinder while axial action, it is possible to protection oil cylinder is not affected by radial force.
Summary of the invention
The invention provides the movable support mechanism of a kind of box type girder base-supporting trestle, in order to support oil cylinder axial action to protect oil cylinder in time, thus overcome the deficiencies in the prior art.
The present invention includes trestle main body and movable support mechanism, described movable support mechanism is arranged between two box type girders of trestle main body, the medial wall of described box type girder arranges upper and lower two closed slides, i.e. upper rail and lower guideway, movable support mechanism moves along lower guideway, and correspondingly, movable support mechanism includes upper roller, the bottom roller moved along upper rail, lower guideway, bottom roller passes through fluid motor-driven, and box type girder moves along upper roller；
