Description of drawings
Fig. 1 is the structural representation of the construction creeping formwork jacking synchronous control system of the utility model specific embodiment.
Embodiment
Below with reference to accompanying drawing construction creeping formwork jacking synchronous control system of the present utility model is described in further detail, is specially following mode of execution:
As shown in Figure 1, present embodiment is the construction creeping formwork jacking synchronous control system of two cover oil cylinder lifting bodies (corresponding two jacking seats in the plane), this system comprises fuel tank 7, oil pump 8, motor 9, transfer conduit system, two cover oil cylinder lifting bodies, and a synchronous control gear.This transfer conduit system comprises oil suction branch road L1, oil return branch road L2 and solenoid directional control valve 17, every cover oil cylinder lifting body comprises jack 18, Pilot operated check valve 2 and two-bit triplet control valve 4, and this jack 18 has rodless cavity (epicoele) and rod chamber (cavity of resorption).This sync control device is in series by synchronous valve 5 and unidirectional series flow control valve 6.
Two oil cylinder lifting bodies are installed on the mould bases support mechanism 1, jack 18, Pilot operated check valve 2 and two-bit triplet control valve 4 connect and compose the oil inlet passage of oil cylinder lifting body successively, high pressure hose 3 is arranged between Pilot operated check valve 2 and the two-bit triplet control valve 4, and (between jack 18 and the solenoid directional control valve 17) also is provided with a high pressure hose on the oil discharge passage of oil cylinder lifting body.The action of each oil cylinder is all controlled by this two-bit triplet control valve 4, concrete, this two-bit triplet control valve 4 is ball-valve structures, it has a port X who links to each other with sync control device, a port Y who links to each other with corresponding jack 18 and a port Z who links to each other with solenoid directional control valve 17, under the "on" position, X port and the conducting of Y port, under the power failure state, X port and the conducting of Z port.This two-bit triplet control valve 4 is used to control the break-make of fluid, selects for use ball valve that the response frequency raising of valve, leakage rate were prolonged near zero, life-span.Each two-bit triplet control valve 4 all adopts modular design, and volume is little, easy for installation.This Pilot operated check valve 2 can be realized the hydraulic lock function, when hydraulic pipe line runs into unexpected damaged the leakage, oil cylinder still can support weight, guarantee the Security of synchronization of jacking up, Pilot operated check valve 2 in addition can be with carrying a function of changing flexible pipe 3 when load support simultaneously, this Pilot operated check valve 2 is a ball-valve structure, and pilot operated, hydraulic pressure directly moves, and leaks almost nil.Select 10 tons (during 200bar) of carrying for use, range is the oil cylinder of 250mm.
Oil suction branch road L1 is provided with oil suction filter 13, its inlet connects oil pump 8, and outlet is connected with the P end of oil sucting one-way valve 14 and solenoid directional control valve 17 successively, and oil return branch road L2 is provided with return filter 10, it exports connected tank 7, and inlet is connected to the R end of solenoid directional control valve 17 by return check valve 12.This solenoid directional control valve 17 is 3-position 4-way H type solenoid directional control valves, its output terminal B end and A end are connected to jack 18 rod chambers of oil cylinder lifting body and the unidirectional series flow control valve 6 in the sync control device respectively, in addition, also be parallel with a pressure relief valve 16 between the P of solenoid directional control valve 17 end and the R end.Return check valve 12 cracking pressures are set in 3.5bar, make system pipeline be full of oil all the time, prevent sneaking into of air, improve the speed of response of system and carry out precision.Fill valve 11 is in parallel with return check valve 12, when a certain oil cylinder pauses because of a variety of causes, but the form frame system that climbs works on because of the jacking of other oil cylinders, the oil cylinder that the steel mould base of jacking can drive pause works on, promptly the action of oil cylinder piston must need hydraulic oil to replenish at this moment, otherwise will cause to vacuumize and damage pipeline and equipment, so, this repairing oil suction system designed on the pipeline cleverly.System pressure safety valve 16 front ends are provided with pressure gauge 15, and by regulating the working pressure that pressure relief valve 16 (relief valve) can initialization system, when because load variations when causing overpressure, system's automatic overflow is guaranteed the safety of each workpiece of system.Oil suction, return filter 10,13 have cleanliness of hydraulic oil self check sender function, to guarantee the cleaning of fluid.
At two oil cylinder lifting bodies, in sync control device, select synchronous valve 5 for use, the control end of the two-bit triplet control valve 4 of each oil cylinder lifting body all is connected with synchronous valve 5, rising or falling speed information and the instruction of fluid break-make are all by the guide line transmission, so the synchronization control of system relies on automatic adjusting of internal mechanism of synchronous valve 5 to finish fully.Synchronous valve 5 front ends are connected with the unidirectional series flow control valve 6 of highi degree of accuracy, can adjust different speed as required, and creeping formwork is climbed according to friction speed.Unidirectional series flow control valve 6 the other ends are connected with the A port of solenoid directional control valve 17, and in addition, this unidirectional series flow control valve 6 carries the unidirectional return line 19 of a parallel connection.When jacking needs speed governing, can regulate unidirectional series flow control valve 6 and obtain the jacking speed that needs, hydraulic oil enters unidirectional series flow control valve 6 by the A of solenoid directional control valve 17 end and flows to synchronous valve 5 again, finish a jacking, when oil cylinder need be withdrawn,, do not allow hydraulic oil pass through the speed governing end of unidirectional series flow control valve 6 during the oil cylinder withdrawal in order to increase work efficiency, but directly allow hydraulic oil flow back to, thereby fully improve the working efficiency of system through unidirectional return line 19.
In oil cylinder lifting body uphill process, motor 9 and oil pump 8 are supplied with hydraulic oil, process oil suction filter 13 and solenoid directional control valve 17 and sync control device enter jack 18 rodless cavities of oil cylinder lifting body, at this moment, two-bit triplet control valve 4 is in "on" position, be X port and the conducting of Y port, hydraulic oil lifts mould bases support mechanism 1 by jack 18; Oil return is then flowed back to fuel tank 7 from jack 18 rod chambers behind solenoid directional control valve 17, return check valve 12, return filter 10.In the uphill process, if two oil cylinder speed accumulated deficiencies surpass setting value, will underspeed the automatically rate of climb of that too fast relatively oil cylinder of sync control device, the speed for the treatment of are adjusted when consistent, and oil cylinder continues to rise synchronously.
The decline process of oil cylinder lifting body under the effect of heavy duty, realizes that hydraulic oil refluxes by the switching of solenoid directional control valve 17 directions.In the reflux course, change the oil circuit direction by solenoid directional control valve 17, fluid through jack 18 rod chambers, flows back to fuel tank 7 from jack 18 oil cylinder rodless cavities through the R mouth of Pilot operated check valve 2, two-bit triplet control valve 4, solenoid directional control valve 17 from solenoid directional control valve 17 more again behind return check valve 12 and return filter 10.
In addition, this Pilot operated check valve 2 also has a pipeline that leads to jack 18 rod chambers, communicating of this pipeline and rod chamber a little is the remote control mouth, and remote control mouth place is provided with damper, produces the fluid impact endurance test shock to prevent climbing form system in the cylinder process that contracts from normally climbing under the effect of heavy load.
