The mooring rope constant tension hydraulic control loop is characterized in that a hydraulic motor, a first reversing valve, a pilot valve, a second reversing valve, a balance valve, a pilot overflow valve and a hydraulic pump station are included, an opening A of the first reversing valve is connected with an opening A of the hydraulic motor through the balance valve, an opening B of the first reserving valve is connected with an opening B of the hydraulic motor, one oil opening of the pilot overflow valve is communicated with the opening A of the hydraulic motor, the other oil opening of the pilot overflow valve is connected with an electromagnet and then communicated with an opening T of the hydraulic pump station, a first one-way vale is arranged between the opening T of the hydraulic pump station and the opening B of the hydraulic motor, and the other oil opening of the pilot overflow valve is communicated with an oil tank through the second reversing valve and the pilot valve in sequence. By the adoption of the mooring rope constant tension hydraulic control loop of the hauling machine, catastrophic loss situations caused by breaking a mooring rope, damaging a ship and dragging the ship in the seabed can be prevented, and the mooring rope constant tension hydraulic control loop is suitable for controlling mooring rope tension between the hauling machine and the dragged ship.

Description

The permanent tension force hydraulic control circuit of hawser for hauling machine
Technical field
The utility model relates to a kind of hydraulic control device.Specifically, be for controlling the hydraulic control circuit of the tensile force of hawser between hauling machine and ship towed oceangoing ship.
Background technology
In shipbuilding and application, all know, on large ship, be all equipped with hauling machine, to some special boats and ships are carried out to towage.Although utilize hauling machine can realize the towage of boats and ships, on this hauling machine without cable tension control setup, the degree of tension of uncontrollable hawser.Due to without cable tension control setup, when occurring that sea situation changes, while causing boats and ships to move rapidly, on hawser, will produce tensile force, this tensile force can cause hawser fracture, makes boats and ships impaired, even boats and ships is taken off to seabed, causes catastrophic loss.
Utility model content
Problem to be solved in the utility model is to provide the permanent tension force hydraulic control circuit of hawser for a kind of hauling machine.Adopt the permanent tension force hydraulic control circuit of hawser for this hauling machine, can avoid hawser fracture, boats and ships are impaired and boats and ships are taken off to seabed, caused the situation of catastrophic loss to occur.
For addressing the above problem, take following technical scheme:
Hauling machine of the present utility model is to comprise and the coaxial HM Hydraulic Motor being connected of winch volume, the first change-over valve, priority valve, the second change-over valve, balance cock, precursor overflow valve and hydraulic power unit by the permanent tension force hydraulic control circuit of hawser feature, between two hydraulic fluid ports of described balance, be parallel with the second check valve, the A mouth of described the first change-over valve is connected with the A mouth of HM Hydraulic Motor by described balance cock, and the B mouth of described the first change-over valve is directly connected with the B mouth of HM Hydraulic Motor.Described precursor overflow valve is between the A of HM Hydraulic Motor mouth and B mouth, wherein: a hydraulic fluid port of precursor overflow valve is communicated with the A mouth of HM Hydraulic Motor, after another hydraulic fluid port is connected with electromagnet, is communicated with the T mouth of hydraulic power unit.Between the T mouth of hydraulic power unit and the B mouth of HM Hydraulic Motor, have the first check valve, the import of the first check valve and outlet are communicated with the B mouth of HM Hydraulic Motor and the T mouth of hydraulic power unit respectively.Another hydraulic fluid port of precursor overflow valve valve is communicated with fuel tank by described the second change-over valve and priority valve successively.
Take such scheme, have the following advantages:
As can be seen from the above scheme, while working under permanent tension force towage operating mode, first make the second change-over valve obtain electric, precursor overflow valve work, makes the first change-over valve in take-up mode of operation.Then, by the pilot pressure of precursor overflow valve, set permanent Tensity size.In HM Hydraulic Motor, always under take-up state, when hawser load diminishes, hauling machine can reclaim hawser, 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, makes HM Hydraulic Motor reversion, hawser is emitted, until load is reduced to the setting value of precursor overflow valve.Thereby the hawser of having avoided causing because tensile force is excessive fracture, boats and ships are impaired and boats and ships are taken off to seabed, caused the situation of catastrophic loss to occur.
Accompanying drawing explanation
Fig. 1 is the permanent tension force hydraulic control circuit of hawser schematic diagram for hauling machine of the present utility model.
The specific embodiment
As shown in Figure 1, hauling machine of the present utility model comprises and the coaxial HM Hydraulic Motor being connected 4 of winch volume, the first change-over valve 1, priority valve 6, the second change-over valve 5, balance cock 2, precursor overflow valve 3 and hydraulic power unit with the permanent tension force hydraulic control circuit of hawser, wherein, between two hydraulic fluid ports of balance cock 2, be parallel with the second check valve 8, the A mouth of described the 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 the 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 of HM Hydraulic Motor 4 mouth and B mouth.On precursor overflow valve 3, have four hydraulic fluid ports, wherein, a hydraulic fluid port is communicated with the A mouth of HM Hydraulic Motor 4, after a hydraulic fluid port is connected with electromagnet, is communicated with the T mouth of hydraulic power unit.The import and the outlet that between the T mouth of hydraulic power unit and the B mouth of HM Hydraulic Motor 4, are provided with the first check valve 7, the first check valves 7 are communicated with the B mouth of HM Hydraulic Motor 4 and the T mouth of hydraulic power unit respectively.Another hydraulic fluid port of described precursor overflow valve 3 is communicated with fuel tank by described the second change-over valve 5 and priority valve 6 successively.
Described the first change-over valve 1 is electro-hydraulic proportion reversing valve.The second change-over valve 5 is two-position four-way solenoid directional control valves.
During work, under permanent tension force towage operating mode, first make the second change-over valve obtain electric, precursor overflow valve work, makes the first change-over valve in take-up mode of operation.Then, by the pilot pressure of precursor overflow valve, set permanent Tensity size.In HM Hydraulic Motor, always under take-up state, when hawser load diminishes, hauling machine can reclaim hawser, 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, makes HM Hydraulic Motor reversion, hawser is emitted, until load is reduced to the setting value of precursor overflow valve.
