Referring to Fig. 3, Fig. 4, Fig. 5, the user mode of the bridge beam body construction equipment of the utility model is shown, in use, a plurality of construction equipments are arranged on the track 8, above the bridge beam body construction equipment, support outboard template 5 through draw-bar seat 35.Track 8 is separately positioned on the both sides of bed die on the construction pedestal, and a plurality of bridge beam body construction equipment branches are located on the both sides track 8, and corresponding one by one the setting; The centre is provided with internal mold 4, and the below is provided with bed die 6, is fixed with upper connecting rod 35a between the corresponding draw-bar seat that is provided with; The below of corresponding side gripper shoe is fixed through a lower link 34a, like this, each template is fixed together; Form die cavity, can in die cavity, be filled to mold materials, form box girder body.After current construction pedestal was accomplished construction, track 8 moved on next construction pedestal in the roller drive lower edge of base.
Come the bridge beam body construction equipment 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 construction equipment in the present embodiment, the bridge beam body construction equipment places on the rail that is provided with on the construction pedestal, and can move along rail; After the construction of accomplishing current 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 construction equipment to be movably walking overstepping the limit and influencing template quality, and cause side form template torsional deformation.Assembling can be debugged after accomplishing, and connects with the mains during debugging, and 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 construction 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 construction equipment that is arranged on the internal mold both sides on the tie rod hole of side gripper shoe be connected, the locking draw-bar seat makes outboard template firmly, stably be arranged on by internal mold and the bed die; Accomplish 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 upper connecting rod, lower link are got 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 in draw-bar seat and the vertical rod is taken off, draw-bar seat can outwards rotate, and makes that the reinforcing bar in the beam body is deviate from; Promote first control lever, first reversal valve vertically descends outboard template 5, promotes 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, the bridge beam body construction equipment moves on rail, and outboard template is shifted to the construction pedestal of appointment in company with the bridge beam body construction 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 hydraulically-controlled 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, any one in the scalable one-way throttle valve makes it reach synchronous like each second hydraulic jack.
Only be the preferred implementation of the utility model below, should be pointed out that above-mentioned preferred implementation should not be regarded as the restriction to the utility model, the protection domain of the utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in spirit that does not break away from the utility model and scope, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
