Abstract
The utility model provides a railway tunnel lining jacking frame which reduces the construction cost, reduces the labor intensity, improves the production efficiency, can adapt to different tunnel sections, and increases bracket supporting force. The railway tunnel lining jacking frame comprises a portal frame, brackets are arranged on the portal frame, an archy die which is supported by an oil cylinder is covered outside the portal frame and the brackets, and the railway tunnel lining jacking frame is characterized in that: a plurality of structures which are continuously arranged at equal intervals are adopted by the portal frame and the brackets; a connecting rib for enhancing the supporting intensity is arranged between two adjacent brackets; each bracket comprises a bracket body, a supporting rod and a supporting oil cylinder; and the bracket bodies and the supporting rods can float up and down under the action of the supporting oil cylinder. The railway tunnel lining jacking frame has a simple structure, is convenient to use, and can reduce the construction cost, reduce the labor intensity and improve the production efficiency, adapt to different tunnel sections, and increase bracket supporting force.
Description
Technical field
The wood invention relates to a kind of equipment that is used for constructing tunnel, relates in particular to a kind of jacking frame that is used for railway tunnel lining.
Background technology
At present, in railway tunnel construction, for the tunnel lining jacking frame; Mainly contain door frame, carriage and arch mould and form, the jacking cylinder and the supporting member that supports the arch mould of Support bracket is housed on the door frame, the cross dimension that the arch mould surrounds immobilizes; Jacking cylinder is fixed on the door frame and adopts the extensive compact form oil cylinder of hydraulic pressure; And door frame generally has only two to be located at respectively outside the arch mould two ends, and the center of two door frames links to each other with truss, and two side templates of arch mould lean on truss support through screw rod; Supporting member adopts screw rod, and support is not established in the side template bottom of arch mould.
The deficiency of this tunnel lining jacking frame is: door frame only adopts two, and carriage is independent respectively, lacks strong support, dislocation under the pressure effect of top template easily; Two side templates of arch mould lean on truss support through screw rod; Two of whole side template is all concentrated on the truss to power, cause stress to concentrate, main is the lateral force that do not produced through the side template fluid concrete by line of force of side direction jack; Be that the side direction jack is prone to produce unstability among a small circle; Cause concrete in forming process, to run mould easily, reduce the lining quality, obviously be not suitable for railway tunnel lining; Since template behind moulding can with concrete have certain bonding, as the template of screw rod supporting role, even after pine is unloaded screw rod; Template also is the not demoulding thereupon; Need block-by-block to unload, therefore leaning on screw rod to support defective one is relatively difficulty of the demoulding, the 2nd, and labor workload is big.Support is not established in existing tunnel lining cutting jacking frame side template bottom in addition, and when making cast, following side form inwardly contracts, and causes template and former concrete jointing positions generation faulting of slab ends, thereby reduces the lining quality.
Summary of the invention
The utility model technical problem to be solved is the technical deficiency to above-mentioned existence, and a kind of reduction construction cost is provided, and reduces labor intensity, and enhances productivity, and can adapt to different tunnel cross-sections, and strengthens the railway tunnel lining jacking frame of bracket support power.
For solving the problems of the technologies described above; The technical scheme of the utility model is following: the railway tunnel lining jacking frame; Comprise contain door frame, door frame is provided with carriage; And be covered with the arch mould that supports by oil cylinder at door frame and carriage, it is characterized in that: described door frame and carriage adopt the structure of a plurality of equidistant continuous settings, are provided with the dowel of strengthening support strength between each adjacent carriage; Described carriage includes pallet body, support bar and support cylinder, and pallet body and support bar can fluctuate under the effect of support cylinder.
In such scheme, described arch mould is a continuous structure, adopts a plurality of templates to be spliced continuously; Its length requires and can change according to constructing tunnel; The arch mould covers the outside of door frame and carriage, and the arch mould is divided into three sections of top template, left template and right templates, adopts between three sections to be articulated and connected; Wherein top template holds out against tunnel top by support cylinder, and left template and right template are adjacent to the tunnel inwall by backform oil top.
In such scheme, described door frame has 3 at least, and they equidistantly distribute along the arch mould in the tunnel, and wherein two door frames lay respectively at the both ends of the surface of arch mould, links to each other with truss through two columns between each door frame.
The principle of the utility model is; Adopt the door frame of frame construction to support, and utilize relocatable carriage and hinged arch mould, can carry out deformation adjustment to the arch mould within the specific limits; Therefore can adapt to the tunnel of different section, satisfy the requirement of constructing tunnel.
The beneficial effect of the utility model is: simple in structure, easy to use, reduce construction cost, and reduce labor intensity, enhance productivity, can adapt to different tunnel cross-sections.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Railway tunnel lining jacking frame as depicted in figs. 1 and 2; Comprise contain door frame 1, door frame 1 is provided with carriage 2; And be covered with the arch mould 5 that supports by oil cylinder at door frame 1 and carriage 2; The structure of wherein said door frame 1 and a plurality of equidistant continuous settings of carriage 2 employings; Be provided with the dowel 11 of strengthening support strength between each adjacent carriage 2, described carriage 2 includes pallet body, support bar 3 and support cylinder 4, and pallet body and support bar 3 can fluctuate under the effect of support cylinder 4; Described arch mould 5 covers the outside of door frame 1 and carriage 2; Arch mould 5 is divided into 8 three sections of top template 6, left template 7 and right templates; Connecting portion between three sections adopts hinged; Wherein top template 6 holds out against tunnel top by support cylinder 4, and left template 7 is adjacent to the tunnel inwall with right template 8 by backform oil top 9.
In the present embodiment, described arch mould 5 is a continuous structure, adopts a plurality of templates to be spliced continuously, and its length requires and can change according to constructing tunnel.
In the present embodiment, described door frame 1 has 3 at least, and they equidistantly distribute along arch mould 5 in the tunnel, and wherein two door frames 1 lay respectively at the both ends of the surface of arch mould 5, links to each other with truss 10 through two columns between each door frame 1.
In the present embodiment, described backform oil top 9 distribution symmetrically and evenly is installed on the door frame 1, and an end on backform oil top 9 is fixedly connected with door frame 1, and an other end withstands arch mould 5.
The utility model adopts the door frame 1 of frame construction to support, and utilizes relocatable carriage 2 and hinged arch mould 5, can carry out deformation adjustment to arch mould 5 within the specific limits, therefore can adapt to the tunnel of different section, satisfies the requirement of constructing tunnel.Adopt the utility model apparatus structure simple, easy to use, reduce construction cost, reduce labor intensity, enhance productivity, can adapt to different tunnel cross-sections.
