Description
Technical field
The present invention relates to ship domain, is a kind of boats and ships and the Quick cable release device of gim peg on the bank.By this device, make ship and bank fasten hawser and fix, when hawser pull surpasses setting value, device makes hawser separate rapidly with ship.
Background technology
When boats and ships rest in harbour, the crewman can fasten hawser on the bitt on harbour, thereby make boats and ships stop, steadily can not float.Existing ship harbour fixedly heaving pile on checking bollard, untying the mooring rope relies on manpower fully, bothersome effort not only, and situation occurs very (as fire in harbour, carry out emergency rescue mission) can not take off fast cable again while needing boats and ships to withdraw harbour rapidly, there is the function of fast de-cable in the urgent need to grasp under this background.
By investigation, find, the region of rivers and lakes fishing boats such as the south of the River are more, for the automatic technology that takes off cable device, active demand arranged.The ocean operation aspect: at island and ship, ship-to-ship carries out in the occasions such as material supply or burst accident relief, as presence of fire, and emergency relief, boats and ships are badly in need of breaking away from fast mutual constraint relation, with protection hull safety.
Due to the marine environment complexity, as the variation of current, wind direction etc., cable stress also will change thereupon, once hawser fracture or break off relations, as found not in time, will cause serious harm to safety of ship.For this reason, be detected the stressing conditions of hawser, be reported to the police, be increased safety of ship.
In the construction and transformation of modernization harbour, de-cable replaces old-fashioned ridding bitt cable has fast become inevitable trend, and the progressively improvement of Quick cable release device also becomes a very important problem of modernization Wharf Construction.
Summary of the invention
When boats and ships are docked in the harbour heaving pile, only rope sling need to be enclosed within on hook and get final product.Hook is locked by block, and external force can't go out hawser from hook lira, and the coupler body mountain is equipped with hangnail, prevents the hawser landing, and safety performance is high.The hard work that two or three people of former cause just can complete, a present people just can easily complete.
During de-cable, hawser pulls grasp, install whole under tension, pulling force sensor detects the pulling force signal, when pulling force surpasses setting value, control center will send early warning signal, and micro controller system (C8051F020) control cylinder moves and drives the block motion and opens hold-down mechanism, grasp is broken away from the constraint of hold-down mechanism, and hawser breaks off relations and unties the mooring rope rapidly.
After de-cable, the torsion spring of installing between grasp and baffle plate has auto-reset function by grasp.Trigger limit switch when grasp resets, the motion of micro controller system (C8051F020) control cylinder then drives the block motion and again locks grasp.
If harbour and boats and ships presence of fire, the extraordinary circumstances such as emergency relief, when the pulling force produced at the departure from port ship does not reach predetermined value, can press danger button, hawser also can take off cable fast, thereby guarantees the safety of harbour and boats and ships, avoids losing further expansion.
Advantages such as this Quick cable release device has easy, laborsaving, and de-cable, automatically reset fast, and the pulling force size is adjustable and be applicable to the needs of different tonnage ship pier moorings.The advantage that pulling force is adjustable more makes this device be suitable for family's use that the pulling force demand is little.
In the situation that run into system crash, boats and ships need to undock, and can pass through the hand change over valve of this device, and manually control cylinder motion is broken off relations hawser.

The specific embodiment
A kind of Quick cable release device, by grasp (1), two side shields (5), hangnail (2), torsion spring (4), bracing frame (7), cylinder (8), pulling force sensor (10), pressure hook block (6), electromagnetic valve (18), micro controller system C8051F020(15), centralized control room (13), cylinder (8), limit switch (20) RS485(14), drive (17) compositions such as touch display screen (16).
When the full automaticity Quick cable release device works, pulling force on hawser increases gradually, the pulling force process that hawser acts on grasp (1) is transferred to pulling force sensor (10), by pulling force sensor, the pulling force size is converted into to digital output signal and is transferred to micro controller system C8051F020(15), C8051F020 is through calculating and result of calculation being transported to touch display screen (16), show actual pull numerical value, simultaneously remote control room is passed through RS485(14) controller of bus and de-cable device communicates, can Long-distance Control take off cable device, when accident or pulling force overrate are arranged, remove touch display screen or monitored control system and early warning occurs, radio remote controller separately is housed, as remote control system of mobile phone, the IPAD command and control system, the Android system command and control system, carry out remote real_time control and early warning.
During work, hook (1) is subject to a permanent pulling force under normal circumstances, and hook (1) tail end is blocked by pressure hook block gear (6), and simultaneously, hawser is subject to the constraint of hangnail, and hangnail consists of spring steel, and flexible makes hawser be difficult for breaking away from coupler body.Pressure hook block (6) and cylinder (8) projecting shaft are hinged, and normal circumstances lower cylinder (8) is inner air pressure, and this air pressure provides power, prevents that hook from rotating because of hawser pull.When pulling force reaches the pulling force setting value, will pass through sensor (9) to (18) signals of solenoid electric valve, now cylinder reversing sense motion, complete de-putting.On hook shaft, torsion spring (4) is equipped with in both sides, and the hook under free state (1) is got back to initial position under the effect of torsion spring.Hook (1) is when getting back to initial position, the hook tail end is pushed down limit switch (20), and give a signal to solenoid electric valve (18) simultaneously, cylinder (8) is reversing sense motion again now, under the effect of cylinder (8), pressure hook block (6) blocks again the hook tail end, like this, has just completed once the de-journey of letting slip.
Running in particular cases (as fire, emergency rescue mission etc.), boats and ships need to undock rapidly, when the pulling force produced at the departure from port ship does not reach predetermined value, can press danger button, and hawser also can take off cable fast.
In the situation that run into system crash, boats and ships need to undock, and can pass through the hand change over valve of this device, and manually control cylinder motion is broken off relations hawser.
