Abstract
The utility model relates to a hydraulic controller for integral lift of a super large tonnage member, composed of an oil pressure gauge, a final stage synchronous flow dividing valve, a main synchronous flow dividing valve, an oil pump, and a motor. An overflow valve is respectively arranged between an oil return way and the flow dividing outlet of the final stage synchronous flow dividing valve which is connected with each suspension point. With the adoption of the utility model, when super large tonnage members are integrally lifted, the balance of the lifting force of each suspension point and the integral synchronous operation can be ensured, effectively preventing the condition of deformation of members and the overload of the bearing capacity of some jacks from happening; meanwhile, the use safety of lifting equipment can be ensured. The utility model has the advantages of simple structure, low cost, and easy control.
Description
The utility model relates to a kind of whole hydraulic control device that promotes of super-tonnage member that is used to control.
Be to utilize many lifting jack (being generally tens of) that are arranged on a plurality of suspension centres (four above suspension centres) to carry out to overweight, the whole lifting of super large member at present, because the mass distribution of member can not be even, thereby make the actual carrying capacity of each suspension centre lifting jack unequal everywhere.For this reason, in the integral body of super-tonnage member promoted, the control technique that the employing Proportional valve that has combines with computer guaranteed each suspension centre lifting force equilibrium and whole synchronous lifting the, the height but the employing computer is controlled cost, control technique complexity; Also there is the synchronized splitter of employing valve to realize whole lifting synchronously, because there is streaming error in the synchronized splitter valve, certainly will form the accumulation of error some suspension centre lifting force is increased, cause the lifting displacement amount of each suspension centre unequal, might cause the deformation of member or some jack bearing capacity overburdening.
The utility model purpose is to provide a kind of super-tonnage simple in structure, with low cost the whole hydraulic control device that promotes, and adopts this device can effectively guarantee the balanced and whole lifting synchronously of each suspension centre lifting force in the whole lifting to the super-tonnage member.
For achieving the above object, technical solution of the present utility model is to be respectively arranged with relief valve between the shunting delivery outlet of the final stage synchronized splitter valve that is connected with each suspension centre and oil circuit.Lifting jack oil circuit UNICOM on one of final stage synchronized splitter valve shunting output circuit and the suspension centre, the bearing capacity that promotes jack according to each suspension centre is set the overflow oil pressure that is connected relief valve on this shunting delivery outlet, even the synchronized splitter valve exists the streaming error and the accumulation of error in lifting process, make certain suspension centre rise comparatively fast, causing promoting on this suspension centre the jack lifting force rises, when the oil pressure value suitable with this suspension centre lifting jack bearing capacity reaches the overflow oil pressure of relief valve setting, the part hydraulic oil of supplying with this suspension centre lifting jack flows back to fuel tank by relief valve, make the rate of climb of this suspension centre lifting jack slack-off, thereby reach each suspension centre lifting force purpose of control, promote synchronously to guarantee that each suspension centre lifting force is balanced and whole.
Because the utility model is arranged on relief valve between the final stage synchronized splitter valve stream delivery outlet and oil circuit that is connected with each suspension centre, even each suspension centre actual carrying capacity is unequal, also can set respectively the lifting force of each suspension centre lifting jack; Even there is streaming error in the synchronized splitter valve, the speed of the very fast suspension centre of the rate of climb is slowed down, thereby when integral body promotes the super-tonnage member, can guarantee the balanced and whole synchronous operation of each suspension centre lifting force, and effectively avoid the situation of the deformation of member and some jack bearing capacity overburdening to take place; Simultaneously can also guarantee that lifting means is safe and reliable.This apparatus structure is simple, and is with low cost, and control easily.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1--be the utility model embodiment's structural representation.
As shown in Figure 1, drive oil pump 5 work by motor 6, oil pump 5 by main synchronized splitter valve 4 to two final stage synchronized splitter valve 3 fuel feeding, on the oil circuit of four suspension centres of two final stage synchronized splitter valves, 3 supplies, be connected with hydralic pressure gauge 2, measure the real work oil pressure that promotes jack on the suspension centre, relief valve 1 is separately positioned between final stage synchronized splitter valve 3 four shuntings delivery outlet and oil circuit that is connected with four suspension centres, and the overflow oil pressure of relief valve 1 promotes the jack bearing capacity according to this suspension centre and sets.In lifting, rise comparatively fast as if suspension centre 2, make and promote the rising of jack lifting force on the suspension centre 2, when the oil pressure value suitable with suspension centre 2 lifting jack bearing capacities reaches the overflow oil pressure of relief valve 1 setting, supply with the part hydraulic oil that promotes jack on the suspension centre 2 and flow back to fuel tank by relief valve 1, the rate of climb that makes suspension centre 2 promote jack slows down.
