Description
Technical field
The present invention relates to a kind of hydraulic control device.Specifically, the hydraulic control circuit of the tensile force controlling hawser between hauling machine and ship towed oceangoing ship is used to.
Background technology
All know in shipbuilding and application, large ship is all equipped with hauling machine, to carry out towage to some special boats and ships.Although utilize hauling machine can realize the towage of boats and ships, without cable tension control setup on this hauling machine, the degree of tension of uncontrollable hawser.Due to without cable tension control setup, when occurring that sea situation changes, when causing boats and ships jerky motion, hawser will produce tensile force, this tensile force can cause cable breaks, makes boats and ships impaired, even boats and ships is taken off seabed, cause catastrophic loss.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of hauling machine hawser identical tension hydraulic control circuit.Adopt this hauling machine hawser identical tension hydraulic control circuit, cable breaks, boats and ships can be avoided impaired and boats and ships taken off seabed, cause the situation of catastrophic loss to occur.
For solving the problem, take following technical scheme:
Hauling machine hawser identical tension hydraulic control circuit feature of the present invention comprises rolling up the coaxial HM Hydraulic Motor, the first change-over valve, priority valve, the second change-over valve, balance cock, precursor overflow valve and the hydraulic power unit that are connected with winch, the second check valve is parallel with between two hydraulic fluid ports of described balance, the A mouth of described first change-over valve is connected with the A mouth of HM Hydraulic Motor by described balance cock, and the B mouth of described first change-over valve is directly connected with the B mouth of HM Hydraulic Motor.Described precursor overflow valve is between the A mouth of HM Hydraulic Motor and B mouth, wherein: first hydraulic fluid port of precursor overflow valve is communicated with the A mouth of HM Hydraulic Motor, is communicated with after second hydraulic fluid port is connected with electromagnet with the T mouth of hydraulic power unit.Have the first check valve between the T mouth of hydraulic power unit and the B mouth of HM Hydraulic Motor, the import of the first check valve is communicated with the T mouth of hydraulic power unit with the B mouth of HM Hydraulic Motor respectively with outlet.Second hydraulic fluid port of precursor overflow valve is communicated with fuel tank with priority valve by described second change-over valve successively.
Take such scheme, have the following advantages:
As can be seen from the above scheme, when working under identical tension towage operating mode, first make the second change-over valve obtain electric, precursor overflow valve work, make the first change-over valve be in take-up mode of operation.Then, by the pilot pressure setting identical tension size of precursor overflow valve.Under HM Hydraulic Motor is in take-up state always, when hawser load diminishes, hawser can reclaim by hauling machine, until load increases to the setting value of precursor overflow valve.When hawser load increases, the hydraulic fluid port B pressure of HM Hydraulic Motor is greater than its hydraulic fluid port A, and HM Hydraulic Motor is reversed, and releases, hawser until load is reduced to the setting value of precursor overflow valve.Thus avoid cause because tensile force is excessive cable breaks, boats and ships are impaired and boats and ships are taken off seabed, cause the situation of catastrophic loss to occur.
Accompanying drawing explanation
Fig. 1 is hauling machine hawser identical tension hydraulic control circuit schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, hauling machine hawser identical tension hydraulic control circuit of the present invention comprises rolls up coaxial HM Hydraulic Motor 4, first change-over valve 1, priority valve 6, second change-over valve 5, balance cock 2, precursor overflow valve 3 and the hydraulic power unit that are connected with winch, wherein, the second check valve 8 is parallel with between two hydraulic fluid ports of balance cock 2, the A mouth of described first change-over valve 1 is connected with the A mouth of HM Hydraulic Motor 4 by balance cock 2, and the B mouth of described first change-over valve 1 is directly connected with the B mouth of HM Hydraulic Motor 4.Described precursor overflow valve 3 is between the A mouth of HM Hydraulic Motor 4 and B mouth.Precursor overflow valve 3 has four hydraulic fluid ports, wherein, first hydraulic fluid port is communicated with the A mouth of HM Hydraulic Motor 4, is communicated with after second hydraulic fluid port is connected with electromagnet with the T mouth of hydraulic power unit.The import being provided with the first check valve 7, first check valve 7 between the T mouth of hydraulic power unit and the B mouth of HM Hydraulic Motor 4 is communicated with the T mouth of hydraulic power unit with the B mouth of HM Hydraulic Motor 4 respectively with exporting.Second hydraulic fluid port of described precursor overflow valve 3 is communicated with fuel tank with priority valve 6 by described second change-over valve 5 successively.
Described first change-over valve 1 is electro-hydraulic proportion reversing valve.Second change-over valve 5 is two-position four-way solenoid directional control valves.
During work, under identical tension towage operating mode, first make the second change-over valve obtain electric, precursor overflow valve work, make the first change-over valve be in take-up mode of operation.Then, by the pilot pressure setting identical tension size of precursor overflow valve.Under HM Hydraulic Motor is in take-up state always, when hawser load diminishes, hawser can reclaim by hauling machine, until load increases to the setting value of precursor overflow valve.When hawser load increases, the hydraulic fluid port B pressure of HM Hydraulic Motor is greater than its hydraulic fluid port A, and HM Hydraulic Motor is reversed, and releases, hawser until load is reduced to the setting value of precursor overflow valve.
