Description
Technical field
The utility model relates to a kind of working jumbo for tunnel lining.
Background technology
Working jumbo for tunnel lining is a kind of plant equipment of using during secondary lining in the constructing tunnel, in railway, highway and Hydraulic and Hydro-Power Engineering construction, is widely used.Adopt this equipment, can improve the concrete lining quality, accelerating construction progress is raised the efficiency.In the constructing tunnel design, because geology country rock type is different, and the difference of tunnel turning radius, every tunnel cross-section size is different, even the cross dimensions of same each section of tunnel also often changes.If each section is made a formwork jumbo, obviously can strengthen construction cost, therefore just must formwork jumbo be designed to variable cross-section uses chassis, to adapt to the construction needs of different section.
Summary of the invention
The technical problem that the utility model will solve is, a kind of continuous variable cross section working jumbo for tunnel lining is provided, to overcome deficiencies such as construction needs, the construction cost that can not be suitable for different section that prior art exists be big.
The utility model adopts following technical scheme: it comprises template system, portal frame system, running gear, supporting mechanism and hydraulic system; Portal frame system comprises that door frame crossbeam, door frame move oil cylinder, door frame middle cross beam, limit mould locating support, shifted laterally wheel, column; The two ends that door frame moves oil cylinder connect column and perpendicular support respectively; Limit mould locating support is connected in the outside of column, and the shifted laterally wheel is arranged on the underbeam; In the cross section of chassis; The column of both sides connects through door frame crossbeam, door frame middle cross beam respectively, and in the longitudinal section of chassis, the column of both sides connects through upper beam, central sill, underbeam respectively; Between the column that faces mutually, be provided with cross support, running gear is connected with underbeam with column respectively; Wherein the door frame crossbeam comprises inner upright mounting crossbeam, outer mast crossbeam, and the inner upright mounting crossbeam is arranged in the outer mast crossbeam, and the door frame middle cross beam is drawn together inner upright mounting middle cross beam, outer mast middle cross beam, and the inner upright mounting middle cross beam is arranged in the outer mast middle cross beam.
Inner upright mounting crossbeam, outer mast crossbeam and inner upright mounting middle cross beam, outer mast middle cross beam are provided with pin.
Between door frame crossbeam and door frame middle cross beam, be connected with diagonal brace, perpendicular support, between column and door frame middle cross beam, be connected with diagonal brace down.
Door frame crossbeam in the chassis and door frame middle cross beam adopt the common hot rolling 20mm of GB steel plate assembly welding to form; It is the primary structure of realizing the chassis changes of section; The design of the inner employing of door frame crossbeam and door frame middle cross beam chute; Be divided into inner upright mounting crossbeam, outer mast crossbeam, inner upright mounting middle cross beam, outer mast middle cross beam; Inner upright mounting crossbeam, inner upright mounting middle cross beam break away moving to realize widening of section under the effect of moving oil cylinder to one along chute, position with alignment pin when inside and outside crossbeam relatively slides to the section working condition requirement.When the chassis door frame designs, satisfy the changes of section requirement, also must consider the performance of passing through of its stiffness and strength and large-scale construction equipment except considering that door frame slides; Formulate the reasonable process method according to precision and quality specifications in the fabrication and processing; Emphasis is a technology for blanking, prevents that welding deformation from guaranteeing the borehole accuracy that connects, and guarantees the welding quality of weld seam, anti-leak-stopping weldering dry joint.
The utility model moves oil cylinder through door frame and drives inside and outside door frame crossbeam; The requirement of variable cross-section has been realized in the relative slip and the location of inside and outside door frame middle cross beam, and the construction that the enough formwork jumbos of ability are suitable for different section needs; Greatly reduce construction cost, have good economic benefit.
