Abstract
The utility model discloses a two hoisting point hydraulic hoist machine synchro control structures of gate installs in two same hydraulic cylinder's of two hoisting points of having corresponding gate hydraulic hoist machine, in this synchro control structure, be equipped with oil tank to two hydraulic cylinder's oil circuit, be equipped with mechanical governing valve respectively on two oil circuits, there is an oil circuit in pole chamber, the parallelly connected pipeline of installing two tee bend magnetic ball valve respectively at hydraulic cylinder, all install the aperture appearance on every hydraulic cylinder, aperture appearance and two the equal UNICOM of tee bend magnetic ball valve to same PLC controllers. The utility model discloses a synchro control structure has realized two hydraulic cylinder's of hydraulic hoist machine quick synchronization and good synchronous precision under lower cost.
Description
Technical field
The utility model relates to a kind of synchronous control structure, particularly relates to the synchronous control structure used in double hanging point hydraulic headstock gears of gate.
Background technology
On large hydropower station and ship lock, it is often provided with large span, large-tonnage gate, needs owing to quality is huge to use 2 liftings., the motion of the oil cylinder that the two and suspension centre connect firmly should keep identical displacement, thus realize synchronizing.In order to realize synchronizing, needing moves to two oil cylinders realizes necessary regulation and control, and this regulation and control structure are referred to as Synchronization Control or synchronization loop.
Having two ways can realize Synchronization Control traditionally, common mode is to use choke valve or flow speed control valve synchronization loop, and this infrastructure cost is low, but needs manual adjustment, complex operation every time, and performance accuracy is low, it is impossible to realize precise synchronization；Another way is to use proportioning valve, and this mode has degree of precision, but needs more electrical equipment, and lattice are expensive, debugs loaded down with trivial details valency, and requires the highest to the cleannes of fluid, is difficult to adapt to the actual working environment of domestic gate hoist.
Summary of the invention
For the deficiencies in the prior art, the utility model discloses double hanging point hydraulic headstock gear synchronous control structures of a kind of gate, disclosed structure, based on traditional mechanical speed governors valve, effectively controls the cost of product；It is aided with this numerical controls some to synchronize simultaneously, improves degree of regulation.
Specifically, the utility model is achieved by the following technical solution:
Double hanging point hydraulic headstock gear synchronous control structures of a kind of gate, in the hydraulic headstock gear of two the same hydraulic jacks being installed on double suspension centres with corresponding gate；In this synchronous control structure, it is provided with the fuel tank oil circuit to two hydraulic jacks, two oil circuits are respectively equipped with mechanical speed governors valve；In the oil circuit of the rod chamber of hydraulic jack, it is installed in parallel the pipeline of a two-bit triplet Solenoid ball valve respectively；Each hydraulic jack is mounted on aperture instrument；Aperture instrument and two-bit triplet Solenoid ball valve are all connected to same PLC.
Pass through said structure, two cylinders are allowed substantially to synchronize first with manual mechanical speed governors valve manual coarse adjustment in use, detect that sending correction to Solenoid ball valve when deviation occur in two oil cylinder displacements instructs at PLC by aperture instrument, obtain electric to the Solenoid ball valve on that fast side cylinder oil circuit, a part of fluid oil return box of the rod chamber of that side cylinder corresponding, this oil cylinder slows down, it is achieved the Fast synchronization of two oil cylinders.Controlling to synchronize by said structure, it is ensured that synchronization accuracy, be the most not only not required to manual regulation repeatedly but also be not required to the electric adjustment of complexity, element cost is the lowest.
Further, mechanical speed governors valve is provided with cowling panel, in order to change the flow direction of oil circuit when necessary.
In the utility model, the deviation of stroke of the hydraulic jack that the condition of PLC triggering two-bit triplet Solenoid ball valve detects by the aperture instrument connected is not less than 10mm.
Under above-mentioned displacement error limit, it is therefore prevented that the frequent starting of Solenoid ball valve, it is ensured that the service life of product.
Accompanying drawing explanation
Fig. 1 is the structural framing schematic diagram of synchronous control structure of the present utility model.
Detailed description of the invention
In following, applicant combines accompanying drawing and synchronous control structure of the present utility model has carried out the explanation of principle.It should be readily apparent to one skilled in the art that structure is commercially available with reference to the accompanying drawings or connects the circuit drawing obtaining correspondence voluntarily.
With reference to Fig. 1, synchronous control structure of the present utility model, being mounted in hydraulic headstock gear, this hydraulic headstock gear has two hydraulic jacks B1, B2, corresponds respectively to two suspension centres A2, A3 on Gate A1, thus is moved it by oil pressure.In this control structure, it is provided with the oil circuit of fuel tank F to two hydraulic jack, two oil circuits are respectively equipped with mechanical speed governors valve C1, C2, control two oil cylinders by mechanical adjustment and be generally synchronized with the movement；On pipeline, parallel connection is provided with two Solenoid ball valves D1, D2, oil cylinder is provided with aperture instrument B3, the B4 that can detect oil cylinder stroke, aperture instrument and Solenoid ball valve are connected to PLC E, when PLC receives two oil cylinder stroke deviations more than 10mm signal, PLC sends correction instruction, obtains electric to the Solenoid ball valve on that fast side cylinder oil circuit, the part fluid oil return box of the rod chamber of that side cylinder, this oil cylinder slows down, it is achieved that the effect that two oil cylinders will soon synchronize.
Further, mechanical speed governors valve C1, C2 are respectively equipped with cowling panel C3, the C4 matched.
