Description
Technical field
The present invention relates to ship domain, particularly to marine shafting centrage aligning regulating device and method.
Background technology
Newly build up and the boats and ships of already out dock, because of some reason need again to lie up repairing time, depressed place owing to being entered is no longer dock during shipbuilding, but enter other docks, therefore, it is impossible to axle system when finding construction again, rudder system datum line, this needs to reorientate the centrage of rudder system of axle system after just requiring to reprocess dockage, for the requirement to boats and ships quality control, need to be accurately positioned the centrage of axle system, it is ensured that axle, rudder system centre deviation meet IACS standard-required.At present, reprocess boats and ships and often enter dry-docking or floating dock is keeped in repair, after dockage, positioned by laser device shaft centrage, owing to existing alignment is by being manually directed at, therefore, centrage setting accuracy is low, and need to be by long-time debugging, with close to exact value, inefficiency, intensity is big, takes time and effort；And need laser device is carried out Level-adjusting before using laser device, simultaneously, the adjustment process of laser device to be guaranteed is to carry out under a stable ambient condition, but when repairing in boats and ships are into floating dock, owing to internal medium is unstable, therefore, the alignment error of laser device is big, and its result measured the most does not has actual reference significance.
For solving the problems referred to above, it is accurately positioned center line of shafting if necessary, then needs to split out the stern tube shaft of boats and ships, further according to the flange center before and after stern pipe, by using laser device to find out center line of shafting, but this kind of method cost is high, long construction period, and during dismounting stern tube shaft, it is high that Axial parts damages risk, and operability is the strongest, simultaneously, if implementing this kind of method in floating dock, due to environment unstable factor, it is equally easy to cause centrage position error big.
Summary of the invention
It is desirable to provide a kind of be directed at simple, precision high, ambient adaptability strong and the marine shafting centrage aligning regulating device of simple in construction and method, improves the work efficiency of marine shafting centrage alignment.
A kind of marine shafting centrage aligning regulating device of the present invention, including the rotating disk being tightened on screw shaft of ship, rotating disk inner surface is provided with the female thread matched with the external screw thread on stern tube shaft, disc surfaces is provided perpendicular to the connecting rod of rotating disk, the screwed hole of horizontally toward center of turntable it is provided with in described connecting rod, studdle connects as one with connecting rod in screwing in screwed hole, and studdle has generating laser towards connection on one end of center of turntable.
A kind of marine shafting centrage alignment control method of the present invention, its step includes:
1) rotating disk is tightened on stern tube shaft, rotates the studdle horizontal level with regulation generating laser, meanwhile, the vertical position of manual adjustment generating laser, make the generating laser on studdle be generally in stern tube shaft centerline；
2) fixing a piece of paper at the laser pick-off on boats and ships, the laser spots that generating laser produces is shown on profile-paper；
3) rotating stern tube shaft one to enclose, the laser spots making generating laser produce depicts circus movement track on profile-paper, determines the center of circle of circus movement track；
4) rotate the studdle horizontal level with regulation generating laser, and by the vertical position of manual adjustment generating laser, the laser spots making generating laser produce overlaps with the center of circle determined in step 3)；
5) stern tube shaft is again rotated, if laser spots is all the time in same point, it is determined that the laser rays that generating laser produces is the extended line of center line of shafting；If laser spots is not in same point, again form circus movement track, then repeat step 3) to step 5), until laser spots in motor process all the time till same point.
nullA kind of marine shafting centrage aligning regulating device of the present invention and method，Owing to aligning regulating device is to be directly anchored on stern tube shaft，And the paper of display laser emission point is integrally fixed on boats and ships，Therefore，Even if in floating dock，The environment of its instability does not interferes with the accurate alignment of center line of shafting yet，Simultaneously，Due to generating laser present position substantially in the centerline of stern tube shaft，Therefore，While rotating stern tube shaft，If there is deviation with the home position of stern tube shaft in the position of generating laser，Then generating laser is with in stern tube shaft rotation process，Its laser spots will move in a circle centered by the stern tube shaft center of circle，Thus overlapped with the center of circle of circus movement track by the laser spots of studdle and fine setting screw rod regulation generating laser，Can easily determine the centrage of stern tube shaft，Method is simple，The work efficiency of centrage alignment is greatly improved，Visible，Can the centrage of quick locating shaft system by this kind of centrage aligning regulating device and control method，Alignment is simple、Precision is high、Ambient adaptability is strong and simple in construction，Greatly reduce the difficulty of original alignment methods，Time saving and energy saving，Work efficiency is high，Avoid dismounting stern tube shaft and damage the risk of parts.
