Description

Portable measuring rod for accurately measuring position of rudder horn during ship building

Technical Field

The utility model belongs to the technical field of shipbuilding measures, a measuring stick of accurate measurement rudder horn position is hung in portable shipbuilding is related to.

Background

The modern ship building method is mainly characterized in that a section building method is adopted, steel plates and sectional materials are assembled into individual ship body sections through blanking, cutting, processing, assembling and welding, then the manufactured sections are assembled together to form a total section, finally the total section is assembled into a complete ship body, and then outfitting operation is carried out to carry the ship body into a whole ship.

The precision control is always a vital part in the ship building process, so that special tools must be adopted for precision control of a plurality of nodes, and some nodes must be measured and do not have the positions of traditional measurement conditions, such as simulation carrying of head and tail sections. Under the current shipbuilding condition, limited by safety tools, a plurality of people with marginal measurement precision cannot reach the shipbuilding condition, but the measurement error is increased by adopting the mode measurement without the prism. Particularly, under the conditions that the foot hand is lacked and a hydraulic vehicle cannot be adopted, the position of an axle rudder hole, which cannot be reached by a precision control personnel at all, has more measurement limiting conditions, and the traditional precision measurement tool and the measurement method are difficult to operate and complete at the positions of the axle rudder hole and a rudder horn. The traditional precision measuring tools need precision personnel to ascend to an axle rudder hole and hang a rudder arm for measurement, so that a scaffold needs to be built or a hydraulic vehicle needs to be used for operation, and labor and time are wasted; and the remote optical measurement mode is difficult to ensure the measurement precision. The measuring stick of the accurate measurement of current shipbuilding and hanging rudder arm position is the combination pole, mostly is plug-in connection, and its shortcoming is: the connection between the measuring rods is not tight enough, the measuring rods are easy to shake in the using process, the measuring precision is influenced, and the existing measuring rods are not portable enough.

Therefore, a special measuring rod needs to be designed, which not only can be stably and firmly connected, but also can meet the requirement of portability.
