Detailed description of the invention
Below according to accompanying drawing, this utility model is described further.
Such as Fig. 1, shown in Fig. 2, pedestal 10 is provided with servo motor 11, and the outfan of described servo motor 11 connects one end of arm 7, and the other end of arm 7 connects weight cage 2；Servo motor 11 uses connector to be connected with capstan system 9, and capstan system 9 connects, by rope and angular compensator 14, long computing unit 4 of restricting, and described long computing unit 4 of restricting is positioned at the top of arm 7 other end；The front end of described pedestal 10 connects one end of hydraulic connecting rod 13, and the other end of hydraulic connecting rod 13 connects the middle part of arm 7, and the lower section in the middle part of arm 7 connects weight placing trough 8.
Be positioned in the pedestal 10 of servo motor 11 side is provided with hydraulic pressure and air system unit 16, hydraulic pressure and air system unit 16 be provided with hydraulic press 12, hydraulic pressure and air system unit 16 be arranged over control chamber 15.
Be positioned at the arm 7 above weight placing trough 8 and be provided with pulling force connecting rod 6, pulling force connecting rod 6 be respectively provided on two sides with air bottle 5.
It is positioned on the arm 7 above weight cage 2 connection balance ring joint 1.
Control chamber 15 connects one end of electric box 18, and the other end of electric box 18 connects CPU 19.
As shown in Fig. 1 ~ Fig. 2, pedestal 10 being installed on the gunnel of main deck, make pedestal 10 parallel with deck as far as possible, during to ensure that weight 3 is transferred, the angle with pedestal 10 is 90 °.After installation, whole device parameter under different operating modes is as follows: height is 3550mm(armed state), 1665mm(duty)；Width is 1400mm.
Spread length outside ship side: 1700mm(armed state), 5115mm(duty).
After confirming that installation is errorless, adjusting the pressure of air bottle 5, normal range is between 6bar ~ 10bar.
Entering after duty, electric box 18 in Fig. 2 and CPU 19 are all by outside 230V three-phase alternating current, and 50 ~ 60HZ supports work.First, CPU 19 can be from control chamber 15 receiving balance ring joint 1, the information of the restrict sensors such as long computing unit 4, air bottle 5, hydraulic press 12, determine that device is standby, confirm together errorless after, can start 3 times water of weight and provide location reference operation.
During operation, step one, stretch out arm: put down arm 7, from the 0 of armed state °, transfer to almost parallel with deck position, now weight cage 2 and weight 3 leave weight placing trough 8, along with transferring of arm, gradually stretch out ship side.
Step 2, water under weight: ordered to weight cage 2 by the guidance panel of control chamber 15 so that it is be gradually reduced, now, restrict long computing unit 4, air bottle 5, pulling force connecting rod 6, capstan system 9, servo motor 11, hydrostatic gauge 12, hydraulic connecting rod 13 and angular compensator 14 work simultaneously, calculate in real time and transmit the result to CPU 19.Along with weight 3 constantly declines, and enter in sea water, suffered by pulling force connecting rod 6, pulling force can be gradually lowered, until weight arrives seabed, in conjunction with the density of weight, shape, material, and density of sea water etc., now pulling force suffered by pulling force connecting rod 6 is between tight and between unclamping, system think can using this weight as with reference to and carry out positioning, moving the actions such as ship.
Step 3, moves ship: the normal ship time that moves need not do any action at this device, and CPU 19 can judge according to information such as air pressure, angle and the hawser pulls transmitted from electric box 18, and this device is whether in reasonable working range.Having two conditions can cause moving ship time data process system and judge that this reference system is not suitable for being continuing with, one is hawser pull, when hawser pull is excessive, illustrates that pouring weight may be towed movement by ship, so can not reach the effect of location；If hawser pull is too small, a kind of probability is that wirerope has ruptured, and this is the most extreme situation certainly.Another kind of arm hanging type can be caused to rise situation that relocation system is not suitable for using is, wirerope exceedes range with the angle of balance ring joint 1, generally this angle is ± 25 °, so the distance from sea level to seabed is the biggest, the range of this reference system is the biggest.Simultaneously as restrict, long computing unit 4 all reaches 0.1m and 0.1 ° with the angle computer precision balancing ring joint 1, so the precision when location will be higher than global positioning systems such as GPS, and then operating accuracy and efficiency is greatly enhanced.
About the scope of application of this set location reference unit, electric box 18 and CPU 19 can working condition be that temperature is 0 ~+55 ° of C, and the working condition of above-decks equipment is-15 ~+65 ° of C(duties), 25 ~ 70 ° of C(armed states)；Humidity environment is 20 ~ 100%(duty), 0 ~ 100%(armed state)；Wind environment is 0 ~ 80knots；If sea freezes, ice sheet maximum gauge may not exceed 100mm；IP grade is the IP grade 22 of electric box 18 and CPU 19, the IP class 56 of above-decks equipment.
