Description
Technical field
The utility model relates to kind of a hydraulic pressure steel form carrier that is used for the tunnel build, especially a kind of gantry type hydraulic pressure steel form carrier.
Background technology
At present, gantry type hydraulic pressure steel form carrier is to drive trolley running with the Motor Drive walking mechanism, utilizes the very heavy adjustment template of hydraulic jack and spiral to put in place and receives the machine of the tunnel concrete moulding of mould.It has that cost is lower, reliable in structure, easy to operate, advantage such as lining cutting speed fast, the tunnel forming surface is good, is widely used in power station, railway and the highway tunnel.The active length of a circulation of this chassis lining cutting is generally 6m, 9m, 10.5m or 12m.It is adapted to any arched section, no matter be the single-track railway tunnel, or three track freeway tunnels etc.
Gantry type hydraulic pressure steel form carrier generally by template system, carriage, translation mechanism, door frame, principal and subordinate's walking mechanism, side hydraulic oil cylinder, lateral-supporting is very heavy, bearing bracket is very heavy, door frame supporting is very heavy etc. forms.
Template system generally constitutes the joint of one on lateral cross section template by polylith backform and two limit moulds, unifies by bolt between the backform of every joint template and the backform, connects by cutting with scissors gudgeon between Bian Mo and the backform.Every joint template is generally made same width, the hoop combination that is linked in sequence each other; Vertical then more piece connects and is combined into the lining cutting length that needs, and joint is connected with template between saving and all adopts Bolt Connection.Template is fastened to have and is the working window that yi word pattern is arranged, and the top is equipped with the grouting device adaptive with the delivery pump interface.The template thickness of slab generally also needs to be provided with angle steel about spacing 250mm as reinforcing rib for the template of broad generally about 10mm.Because the template top is stressed bigger, be intensity and the local unlikely distortion that guarantees template, reach the single form of 1.5m for cross-sectional width, generally also the arc arch bar to be set in the middle.
Carriage mainly bears when casting top concrete and the deadweight of template, holds template on it, the bottom by bearing bracket very heavy and translation mechanism power transmission in door frame.Carriage is made up of three pallet stringers, many carriage crossbeams and carriage column, and the carriage crossbeam comprises limit crossbeam and middle cross beam.The very heavy stress condition that is mainly used in pallet stringer when improving fluid concrete of bearing bracket guarantees the reliable and stable of carriage.
Every hydraulic jumbo is provided with a cover translation mechanism at front and back position, translation mechanism is bearing on the limit crossbeam of door frame, it comprises the translation articulated beam, be arranged on the cross cylinder about the translation articulated beam and be arranged on vertical oil cylinder on the translation articulated beam, vertical oil cylinder upper end links to each other with the longeron of carriage, adjust the vertical location and the demoulding of template by the contraction of oil cylinder, cross cylinder on the translation dolly is used for adjusting the lining cutting center of template, makes itself and tunnel center.
Door frame is the main supporting member of whole chassis, and it is formed by Bolt Connection by crossbeam, column and longeron, connects by articulated beam and diagonal member between each crossbeam and column.Whole door frame guarantees that enough intensity is arranged, rigidity and stability, and its main components is welded by steel plate: the general employing of door frame crossbeam and column is welded into the I-shaped cross-section by steel plate; Longeron generally adopts box section.Generally speaking, the height of door frame is higher, and for guaranteeing the intensity of whole door frame, rigidity and stability are provided with auxiliary bearing diagonal between door frame crossbeam and column.
Every hydraulic jumbo is provided with each two cover of master and slave walking mechanism, and walking mechanism is generally the wheel-track type walking mechanism, and its walking track is preset on the ground, and walking mechanism all is connected on the door frame longeron.
Side hydraulic oil cylinder one end is connected on the template, and the other end is connected on the door frame, both has been used for the template demoulding, also plays a part supporting template simultaneously, according to lining cutting length, generally uses a plurality of side hydraulic oil cylinders.
Be installed in spiral on the door frame very heavy be used for supporting, regulate template position, and the pressure that produces when bearing concrete perfusion.
Very heavy being connected in below the door frame longeron of door frame supporting, during chassis work, it withstands on the rail level of walking track, bears chassis and concrete weight, improves the stress condition of door frame longeron, and door frame is stable when guaranteeing chassis work.
In constructing tunnel, for tunnel, if many hydraulic pressure steel form carriers of respective design have just increased equipment cost with changeable cross section.Therefore consider to utilize a hydraulic pressure steel form carrier to deacclimatize the construction in multiple cross section tunnel, to save construction cost.
At present the time in the face of this type of construction demand, the hydraulic pressure steel form carrier designs according to the sectional dimension of construction earlier, according to the sectional dimension of back construction template system, door frame, carriage, translation articulated beam etc. are made amendment or reformed again, this just comprises widens and two kinds of variable cross-section modes of constriction.
Present existing gantry type hydraulic jumbo can adapt to the variation in cross section within the specific limits by each support length of adjusting vertical support between template system and door frame, the carriage and oblique support, but when changes of section is big, only rely on the adjustment of support member can't guarantee contour curve behind the variable cross-section within the error range that allows, thereby need adjust door frame, carriage, translation articulated beam etc.
The utility model content
In order to overcome the existing time-consuming more deficiency of gantry type hydraulic pressure steel form carrier variable cross-section, technical problem to be solved in the utility model provides a kind of gantry type hydraulic pressure steel form carrier of variable cross-section more easily.
The technical scheme that its technical problem that solves the utility model adopts is: gantry type hydraulic pressure steel form carrier, comprise template system, door frame and be arranged on translation mechanism, carriage and lateral support on the door frame, template system comprises backform and is arranged on the limit mould of backform both sides, lateral support is connected with the limit mould, carriage is connected with backform by vertical the support, translation mechanism comprises the translation articulated beam, and the described lateral support that is connected with the auxilliary door frame of suitable with it a slice at least and this side along at least one longitudinally side of door frame is arranged on the auxilliary door frame.
The bilateral symmetry of described door frame is provided with auxilliary door frame.
