A method of using a slipway auxiliary segmented positioning device

Abstract

The invention relates to the technical field of ship segmented construction, and discloses an auxiliary segmented positioning device for a slipway. A height adjustment mechanism is provided at four corners of a fixed frame, two support rods are provided on the left and right sides of a base, and a laser transmitter rotates. Connected in the middle of the top of the fixed frame, the laser beam emitted by the laser transmitter is on the same plane as the longitudinal centerline of the base, and the hanging hammer is suspended in the middle of the crossbar through the hanging wire; the fixed frame is placed on the slipway, and the longitudinal centerline of the base is in line with the slipway. The center line of the slipway is overlapped, and a method of using the auxiliary sectional positioning device of the slipway is also disclosed. It is in a horizontal state; the position of the ship segment is adjusted so that the multiple laser beams emitted by the rotating laser transmitter all hit the center line of one end face of the ship segment; the invention enables the ship segment to be highly aligned with the center of the platform, Improve positioning efficiency.

Description

technical field [0001] The invention relates to the technical field of ship segment construction, in particular to a method for using a slipway auxiliary segment positioning device. Background technique [0002] In the stage of ship construction, during the process of carrying the ship in sections, the center lines of the top and bottom of the head and tail of the sections need to be aligned with the center line of the slipway. Traditionally, the alignment method of the hanging line hammer is used. The line hammer is greatly affected by environmental factors during the use process, especially When the line length is too long. Due to the large height difference between the sections, the tension of the powder line will cause the line hammer to rotate, and it often takes 5-10 minutes to stabilize. There are also difficulties such as wind blowing and scaffolding blocking. [0003] In the construction stage of a ship, the length of the powder line exceeds 6m or even more than 10...

AI Technical Summary

Problems solved by technology

In the process of extending the ultra-long powder line out of the hull and descending, there are usually scaffoldings blocking it, which takes a while

In the case of wind, the ultra-long powder line is affected by the wind force, and the hammer often swings and deviates. It is necessary to wait for the wind to stop or replace the super-large hammer. The super-large hammer has high requirements on the strength of the powder line and often collapses. broken situation
