A concealed rod for measuring the accuracy of ship segmentation

Abstract

The invention discloses a concealed rod for measuring the accuracy of ship segmentation. The concealed rod comprises: a support rod, on which two targets are fixedly connected, and one end of the support rod has a magnetic force; and two sets of supports structure, the support structure includes a magnet base, a first rod, a second rod, and a fixing piece, the magnet base is adsorbed on the ship structure, and one end of the first rod is universally connected to the magnet base, The other end of the first rod is hinged with one end of the second rod, the other end of the second rod is hinged with the fixing piece, and the fixing piece is fixedly connected with the support rod. The beneficial effects of the invention are to reduce the inconvenience brought by traditional precision measurement tools, reduce unnecessary time, greatly reduce the use process of novice learning, and use the new precision measurement tools to truly liberate hands, thereby improving the accuracy of ship segmentation detection. .

Description

technical field [0001] The invention belongs to the field of ship construction, and in particular relates to a concealed rod for measuring the accuracy of ship segmentation. Background technique [0002] Now all shipbuilding enterprises are implementing regional integrated shipbuilding. The shipbuilding cycle is shortened and the cost is reduced. The tonnage of the ship is getting larger and larger, and the hull is divided into larger and larger segments. The internal structure is also more complicated than before, resulting in a segmented structure. The requirements for dimensional accuracy have also been improved accordingly, and the loading accuracy and hoisting cycle of the hull sections have been lengthened. During the inspection and re-inspection of the sections, the scaffolding was built too densely, which led to some important components when using the total station to measure the sections. It was blocked by scaffolding, so we used traditional concealed rods instead ...

Problems solved by technology

[0002] Now all shipbuilding enterprises are implementing regional integrated shipbuilding, the shipbuilding cycle is shortened and the cost is reduced, the tonnage of the ship is getting larger and larger, the division of the hull is getting bigger and bigger, and the internal structure is more complex than before, resulting in a segmented structure. The requirements for dimensional accuracy have also been correspondingly improved, and the carrying accuracy and hoisting cycle of the hull sections have been lengthened. When inspecting and re-inspecting sections, due to the dense scaffolding built, there are some important components when using total stations to measure sections. Blocked by scaffolding, we used traditional concealed poles instead of reflectors to sense laser measurement segments. However, when using traditional concealed poles, since novices are not familiar with traditional concealed poles during use, hand-held concealed poles When the hand is breathing, the hand will shake with the body's breathing, or the hand slips and accidentally falls from the height of the section, causing serious damage to the measuring tool that cannot be repaired, and the measurement error caused by the loss of the tip of the concealed rod during use.
