Problems solved by technology

The submarine is divided into many compartments by vertical and horizontal walls and platforms, and the pressure-resistant walls are not allowed to drill holes casually. It is also difficult for people to measure the minimum straight-line distance when drawing a ruler manually. The steel wire will sag under the gravity of the earth. thus affecting the measurement accuracy

Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the drawings:

[0021] An application method of electronic total station in submarine ellipticity measurement includes the following steps:

[0022] 1) Draw the centerline O1Y1 of the hull on the slipway, and draw the theoretical line of each auxiliary position;

[0023] 2) Erect the fixed scale 9 in advance, make a mark at the corresponding height position, and paste the reflector. The height of the cross center of the reflector is the same as the height of the center of the hull section after positioning;

[0024] 3) Lift the hull sections on the berth to ensure that the vertical centerline of the hull A1, C1 (A, C) and the ground centerline are on a vertical plane. Use pullers to fix the left and right sides, and use jacks to lift and adjust the height of the sections. Ensure that the horizontal planes DD1 and BB1 of the subsection center of the hull are consistent with the cross center of the reflecto...

Abstract

The invention discloses a method for measuring the ellipticity of a submarine. An electronic total station apparatus is applied to the field for finishing the measurement of the ellipticity of the whole submarine pressure resisting body, wherein the measuring precision can accurately reach 0.5mm. The electronic total station apparatus is matched with a laser transit for accurately positioning and measuring a submarine body tail shaft, an engine seat, a propulsion motor seat, a sonar support seat and other devices. According to the method, the precision of 1mm before welding and 3mm after welding, which is obtained by positioning sectioned erection of a hull passing in Jin can be reached. The method achieves qualitative leap for accelerating modern construction of Chinese navy and propelling the precision shipbuilding.

Description

Technical field [0001] The invention relates to a measurement method, in particular to an application method of an electronic total station in submarine ovality measurement. Background technique [0002] In the existing production, the submarine's ellipticity measurement method is to use the wire drawing method and the laser roundness instrument to measure, that is, the brackets are set up at the two ends of the section, and the center of the hypothetical submarine pressure cabin is drawn on the brackets. Wire and drill holes: 1. The steel wire is passed through the hole and then tightened, and then a ruler is used to measure each point of each rib; 2. The laser roundness instrument irradiates from one end of the hole to the other end, and then measures one by one with a ruler Take the shortest distance from the point on each rib to the laser line and record it. The submarine is divided into many cabins by vertical and horizontal warehouse walls and platforms, and the pressure w...
