Embodiment Construction

[0020] After the diversion cover 4 of the natural gas hydrate comprehensive survey ship is manufactured in the subsection workshop, due to the resources in the factory and the limitation of the berth space, the diversion cover will be divided into three parts, that is, the diversion cover launch array 401 , the shroud accepts array one 402, the shroud accepts array two 403, as figure 1 , where the launch array of the shroud is divided into two from the middle, and transported to the milling machine in the complete machining workshop, the plane of the shroud 4 is milled, and then sent to the turbine workshop, and the shroud 4 is cut with sleepers. The docking of each part is detected by laser, and the nozzle is adjusted so that the horizontal error of the lower plane is ≤1mm. Two positioning code plates 8 are used to mark the positioning pin 9 on the docking place on both sides of the nozzle, as shown in figure 2 As shown, temporarily install the multi-beam bracket 5 and the s...

Abstract

The invention discloses a ship multi-beam acoustic equipment mounting process which is characterized by comprising the following steps of: dividing a guide cover into three parts, milling a mounting surface and a lower surface of the guide cover; assembling the three parts of the guide cover in an inner field, positioning a multi-beam bracket and a closing plate on the guide cover, arranging a drilling thread on the guide cover, then disassembling the multi-beam bracket and the closing plate from the guide cover, manufacturing a positioning code plate of a transmitting array; pushing the guide cover into the downside of the ship by using a roller guide rail, lifting the guide cover by using a crane for leveling, fixing the transmitting array of the guide cover by using the code plate, controlling the welding deformation of the mounting surface by using a welding code plate, welding the guide cover on the ship by adopting a symmetrical interrupted welding mode; pushing the multi-beam bracket to the downside of the guide cover by using the roller guide rail, jacking the multi-beam bracket into the guide cover by using a hydraulic trolley, adjusting the multi-beam bracket, and locking and fixing by using bolts; conveying a multi-beam module to the downside of the guide cover, mounting the multi-beam module in the multi-beam bracket by using bolts through the hydraulic trolley; and mounting the closing plate and fixing by using bolts.

Description

technical field [0001] The invention relates to a ship acoustic equipment installation process, in particular to a ship multi-beam acoustic equipment installation process. Background technique [0002] Multi-beam acoustic equipment is often installed on various marine survey ships. The transducer is composed of multiple multi-beam modules of the transmitting array and receiving array. The transducer is installed in the multi-beam bracket and then fixed horizontally in the hull shroud , the lower surface level of the transducer is very high, and the level error is required to be ≤ 2mm. The conventional installation process is to weld the dome to the bottom of the ship on the berth, then process the lower plane of the dome, drill holes and tap to install multi-beam brackets and modules. However, since the nozzle is located below the baseline of the hull at this time, the size of the nozzle is large and the structure is relatively thin, and the multi-beam acoustic equipment re...
