Description of drawings
Fig. 1 is a kind of structure principle chart of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises hydraulic power source 1, hydraulic oil container 2, electromagnetism three position four-way directional control valve 3, unloading pile-up valve group 11, unloading hydraulic jack 9.
Wherein unload pile-up valve group 11 mainly by two electromagnetism bi-bit bi-pass reversal valves 7 and 8, electromagnetism two position three way directional control valves 5, an adjustable pressure valve 4 and an one way valve 6.
In unloading pile-up valve group 11 inside, A and B mouth are connected the inlet of two electromagnetism bi-bit bi-pass reversal valves 7 and 8 respectively, and electromagnetism bi-bit bi-pass reversal valve 7 and 8 outlet are connected respectively to A1 and B1 mouth; P is connected pressure valve 4 and electromagnetism two position three way directional control valve 5 respectively with the T mouth; One way valve 6 one ends connect electromagnetism two position three way directional control valve 5, and the other end connects electromagnetism bi-bit bi-pass reversal valve 7 outlet and A1 respectively; The gauge port G of unloading pile-up valve group 11 links to each other with pressure valve 4 with the P mouth; The A1 of unloading pile-up valve group 11 is connected oil cylinder accent and the rodless cavity mouth that unloads hydraulic jack 9 respectively with B1, the cylinder body (M end) of unloading hydraulic jack 9 links to each other with operating mechanism 10 with frame 14 respectively with expansion link (N end), restriction 12 is used to reduce the speed of unloading hydraulic jack 9, and restriction 13 is used for the hydraulic flow of P mouth on the restricted passage unloading pile-up valve group 11.
Operating principle of the present utility model is: the sliding formwork machine is in normal paving process; keep two coils of electromagnetism three position four-way directional control valve 3 and the coil of electromagnetism bi-bit bi-pass reversal valve 7 to be in off-position; make the coil electricity of electromagnetism two position three way directional control valve 5 and electromagnetism bi-bit bi-pass reversal valve 8 respectively; the pressure oil of hydraulic power source 1 is via restriction 13 at this moment; electromagnetism two position three way directional control valve 5 and one way valve 6 enter the rod chamber of unloading hydraulic jack 9; the unloading hydraulic jack 9 rodless cavity via restriction 12 through to hydraulic oil container 2; promote operating mechanism 10 so act on the hydraulic coupling of the rod chamber of unloading hydraulic jack 9 by the piston rod that unloads hydraulic jack 9; this lifting force will change operating mechanism and be pressed in gravity above the concrete; the unloading effect is played in operating mechanism 10; can change the size of unload forces by the pressure regulating screw on the adjusting pressure valve 4; thereby make the sliding formwork machine in the difformity road kerb that paves, discharge mechanism can both provide suitable unload forces to operating mechanism.The sliding formwork machine runs in paving process when shutting down; make all electromagnetic valve coils among Fig. 1 be in off-position; the hydraulic oil of rod chamber that one way valve 6 will be sealed unloading hydraulic jack 9 this moment does not sink piston rod, eliminates when shutting down operating mechanism at the lip-deep impression of structure.The sliding formwork machine is after shutdown during ground zero; by coil blackout energising again after several seconds that time-delay relay keeps electromagnetism bi-bit bi-pass reversal valve 8 and electromagnetism two position three way directional control valve 5, the concrete in the time of can avoiding sliding formwork machine ground zero like this below the operating mechanism 10 causes the structure surface step phenomenon to occur because of sclerosis causes that operating mechanism 10 appears on the stage.When the sliding formwork machine promotes operating mechanism before transition; electromagnetism two position three way directional control valve 5 coils keep outage; electromagnetism bi-bit bi-pass reversal valve 7 and 8 coils keep energising; make the b coil electricity of electromagnetism three position four-way directional control valve 3; this is that operating mechanism 10 is raised; when to peak, make the coil blackout of all valves among Fig. 1, operating mechanism 10 is locked in the peak position.When the sliding formwork machine puts down operating mechanism after in place; electromagnetism two position three way directional control valve 5 coils keep outage; electromagnetism bi-bit bi-pass reversal valve 7 and 8 coils keep energising; make a coil electricity of electromagnetism three position four-way directional control valve 3; this is that operating mechanism 10 is put down; when to proper height, make the coil blackout of all valves among Fig. 1, operating mechanism 10 is locked in this position.
