Description

Tunnel lining trolley
(1) technical field
The present invention relates to a kind of construction machine, particularly a kind of constructing tunnel lining shuttering chassis.
(2) background technology
It is the technical scheme of main carrying that the working lining shuttering chassis of existing tunnel all adopts with the chassis, generally comprise chassis and template revenue and expenditure system and operating platform in circular arc trolley formwork, the trolley formwork, its trolley formwork by top template, two side templates, two the soffit formwork individual layer is hinged forms, there is grouting port the top template upper end, this grouting port is connected with Grouting Pipe, grouting pump, is used for concrete pouring.The subject matter that prior art exists is: template supports by chassis entirely, adjust difficulty, intensity is lower, yielding, resistance to compression, anti-floating poor requires high to chassis with steel, walking track planeness, the formwork bracing system complexity, automatically revenue and expenditure, folding, speed of application is slow, and is also high to construction workman's specialty requirement.
(3) summary of the invention
The purpose of this invention is to provide a kind of tunnel lining trolley, solve low, yielding, the easily floating problem, and solution formwork bracing system complexity of template strength, efficient is low, automatically the technical problem of revenue and expenditure, folding.
Be the technical scheme that realizes that purpose of the present invention adopts: this tunnel lining trolley, comprise the template of tunnel shape, chassis and the falsework in the template, template is welded by panel, deckle board and gusset, and grouting port is arranged on the template, this grouting port is connected with filling system, it is characterized in that:
One group of template comprises top template, two side templates and two soffit formworks, cross section at the interface position between top template and two side templates, between two side templates and two soffit formworks is a toroidal, its peripheral edge portion is flat mouthful, connect by hinge, its inner rim horn mouth place connects by adjusting leading screw, and two soffit formwork lower ends are connected with the tunnel by the connector of taking root;
Falsework comprises: below the top template along the axially extended crossbeam of going up longeron, connecting at top template arch position in tunnel, with crossbeam interconnection and the column and the diagonal brace that are connected between axially extended following longeron, crossbeam and the last longeron along the tunnel;
Chassis comprises door frame, crossbeam and running gear, is connected jacking cylinder between the supporting leg of door frame and the running gear, and running gear supports in orbit;
Template revenue and expenditure system: below crossbeam with between the two side template lower ends, be connected at least two pairs of folding arms respectively, folding arm by big arm, forearm is hinged forms, under falsework, be connected the sidesway hydraulic jack between longeron and the chassis crossbeam, be connected the revenue and expenditure hydraulic jack respectively between the big arm lower end of the folding arm of both sides and top template two lower ends, the horn mouth place is connected the folding hydraulic jack between side template and soffit formwork.
Gusset on the above-mentioned template is a U-shaped, its opening both sides and panel welding.
Be connected the anti-leading screw that wafts between above-mentioned top template and the tunnel.
Above-mentioned chassis longitudinal length than template axles to length.
Above-mentioned template is inboard to be connected with operating platform.
Compare beneficial effect of the present invention with existing conventional art: adopting with the template is the scheme of main carrying, the deckle board broad of template, and the U-shaped gusset has increased the integral rigidity of template, and deflection is little, and simultaneously, the steel using amount of template reduces.Cross section at the interface position between top template and two side templates, between two side templates and two soffit formworks is a toroidal, the peripheral edge portion of its template connecting portion is for flat mouthful hinge connects, its inner rim horn mouth place connects by adjusting leading screw, the double-deck connection is convenient to automatic revenue and expenditure folding, be convenient to move in tunnel invagination superimposition, the automaticity height, labor strength is less.Template can not lean on chassis to support, and all technological requirements when template itself is enough to satisfy lining cutting are not yielding, and resistance to compression, anti-floatability are good.Chassis almost only plays the moving die plate effect in construction, less demanding to usefulness steel, the walking track planeness of chassis, and is also not high to construction workman's specialty requirement.Template revenue and expenditure system is all-hydraulic automatic, connecting frame shape falsework on the crossbeam of chassis and between the top template, be connected jacking cylinder between the supporting leg of chassis door frame and the running gear, vertical height of conveniently adjusted chassis and template, under falsework, be connected the sidesway hydraulic jack between longeron and the chassis crossbeam, make things convenient for WidFin.Below crossbeam with between the two side template lower ends, be connected at least two pairs of folding arms respectively, folding arm by big arm, forearm is hinged forms, and makes the template revenue and expenditure more flexible.Be connected the revenue and expenditure hydraulic jack respectively between the big arm lower end of the folding arm of both sides and top template two lower ends, the horn mouth place is connected the folding hydraulic jack between side template and soffit formwork.Have automatic revenue and expenditure, advantage such as equipment is simple to operate, efficient is high, high safety, channel space are big.
