Come the bridge beam body constructing device of present embodiment is described below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5.
Outboard template is installed:
By loop wheel machine cooperation the carrying out disposable assembly unit of outboard template, connect into overall fixed formula large form, then this large form is installed on the support 3 in the bridge beam body constructing device in the present embodiment, the bridge beam body constructing device places on the rail that is provided with on the construction pedestal, and can move along rail, after the construction of finishing current construction pedestal, move to next construction pedestal.Wherein, in the horizontal difference of height requirement≤10mm of rail, can cause when avoiding the bridge beam body constructing device to be movably walking overstepping the limit and influencing template quality, and cause the outboard template torsional deformation.Can debug after assembling is finished, connect with the mains during debugging, actuating motor spurs second control lever, and second reversal valve can make outboard template 5 push ahead and be close to bed die 6.When outboard template 5 need be adjusted to specified altitude assignment, spur first control lever, first reversal valve can make outboard template 5 arrange the height of appointment, aforesaid operations after hours, with upper connecting rod 35a two ends respectively with the relative bridge beam body constructing device equipment that is arranged on the internal mold both sides on draw-bar seat 35 fixing, the locking upper connecting rod, one lower link 34a is inserted in the tie rod hole of bed die below, two ends respectively with the relative bridge beam body constructing device that is arranged on the internal mold both sides on the tie rod hole of bearing diagonal plate connect, the locking draw-bar seat, make outboard template firm, stable is arranged on by internal mold and the bed die, finish the installation of outboard template this moment, outboard template, internal mold and bed die are formed a die cavity, and beam body material is packed in the die cavity, are frozen into mould.
When needing the demoulding behind the beam body solidification forming, then need outboard template is pulled down, during the outboard template form removal, at first will go up, lower link gets loose, unclamp with draw-bar seat, upper connecting rod is taken off from draw-bar seat, lower link is taken out, then the steady pin on draw-bar seat and the column is taken off, draw-bar seat can outwards rotate, make the reinforcing bar in the beam body deviate from, promote first control lever, first reversal valve vertically descends outboard template 5, promote second control lever, second reversal valve returns outboard template 5 along continuous straight runs, breaks away from the beam body, thereby turns back to initial operating position undetermined.Press the forward key on the hydraulic controller or retreat button, bridge beam body production auxiliary equipment moves on rail, and outboard template is shifted to the construction pedestal of appointment in company with bridge beam body production auxiliary equipment.
After 21 work of first hydraulic jack are risen or are dropped to the height of appointment, first reversal valve is returned to meta, the automatic pressurize of hydraulic control one-way valve makes the oil pressure of oil cylinder no longer descend.As high pressure valve is closed, then effect is better, carries out work once more but work as first hydraulic jack, must open high pressure valve, and first hydraulic jack 21 could be worked.Another purpose that this high pressure valve is set is: when the outboard template height is uneven, can close any one in the high pressure valve, make outboard template reach the balance purpose.
Spur second reversal valve, second hydraulic jack is advanced, advance second reversal valve, the second hydraulic jack reposition.
When asynchronous forward, can regulate any one in the one-way throttle valve as each second hydraulic jack, make it reach synchronous.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim institute restricted portion.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
