Slipway auxiliary segmented positioning device and using method thereof

Abstract

The invention relates to the technical field of ship segmented construction, and discloses a slipway auxiliary segmented positioning device which is characterized in that height adjusting mechanisms are arranged at the four corners of a fixing frame, two supporting rods are arranged on the left side and the right side of a base respectively, and a laser transmitter is rotationally connected to themiddle of the top of the fixing frame; a laser beam emitted by the laser emitter and the longitudinal center line of the base are located on the same plane, and a drop hammer is hung in the middle ofthe cross rod through a suspension wire. The fixing frame is disposed on the slipway and the longitudinal center line of the base coincides with the center line of the slippway. The invention furtherdiscloses a using method of the slipway auxiliary segmented positioning device. The method includes the steps of placing the slipway auxiliary segmented positioning device is placed on the slipway, making the longitudinal center line of the fixing frame coincide with the center line of the slipway; adjusting the fixing frame to be in a horizontal state; and adjusting the position of the ship section to enable laser points of a plurality of laser beam emitted by the rotary laser emitter to locate in the center line of the end face of one end of the ship section; the alignment degree of the ship subsections and the center of the slipway is high, and the positioning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ship block construction, in particular to an auxiliary block positioning device for a berth and a method for using the same. Background technique [0002] In the shipbuilding stage, during the loading process of the ship in sections, the centerline of the fore and aft of the section needs to be aligned with the centerline of the berth. Traditionally, the alignment method of the hanging wire hammer is used. During the use of the wire hammer, it is greatly affected by environmental factors, especially It is the case that the line length is too long. Due to the large height difference of the sections, the tightness of the powder line will cause the hammer to rotate. It usually takes 5-10 minutes to stabilize, and there are also difficulties such as wind blowing and scaffolding blocking. [0003] During the construction stage of a ship, when the semi-dimensional or superstructure is hammered, the length of t...

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
