Concealed rod for ship segmentation precision measurement

Abstract

The invention discloses a concealed rod for ship segmentation precision measurement, and the concealed rod comprises a supporting rod which is fixedly connected with two targets, and one end of the supporting rod is provided with a magnetic force; and two sets of support structures, the supporting structure comprises a magnet base, a first rod, a second rod and a fixing piece, the magnet base is attracted to a ship structure, one end of the first rod is universally connected with the magnet base, the other end of the first rod is hinged to one end of the second rod, the other end of the secondrod is hinged to the fixing piece, and the fixing piece is fixedly connected with the supporting rod. The beneficial effects of the invention are that the concealed rod reduces the inconvenience caused by a conventional precision measurement tool, reduces the unnecessary time, greatly reduces the learning use process of a green hand, truly liberates the two hands through employing the new precision measurement tool, and improves the ship segment detection accuracy.

Description

technical field [0001] The invention belongs to the field of shipbuilding, and in particular relates to a concealed rod for measuring the section accuracy of ships. 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, 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 segme...

[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.
