Problems solved by technology

A small work space, because of high-altitude operations, need to use 4-5 aerial work vehicles, but also involves four types of work, there are three-dimensional intersection operations, etc., the risk factor is large, and the work surface is relatively concentrated, in order not to affect When undocking, construction workers often work continuously day and night, fatigued
Safety is seriously threatened, and the quality of work has declined

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] see Figure 1-8 , the operation method that the rudder blade sealing plate of the present invention moves forward comprises the following steps:

[0029] 1) Platform preparation stage: Make a sample box, place the sample box at the position of each rudder blade sealing plate to check its line shape until it matches completely, and cut the margin. Specifically, use a small flat iron of 4mm*15mm to knock out splines according to the line shape of the rudder blade sealing plate, and then weld the splines on the four sides to form a sample box. Such as figure 2 , 3 shown. Then put the sample box at the position of the rudder blade sealing plate to check its line shape, until it is completely matched, draw the margin line and cut, bevel, and polish. Finally, install iron hinges on the sealing plate as needed. Moved a lot of work forward.

[0030] Each rudder blade...

Abstract

The invention discloses an operation method for forward movement of a rudder blade sealing plate. The method comprises the following steps: a platform preparation stage: manufacturing sample boxes, placing the sample boxes at the positions of the rudder blade sealing plates to inspect the line types of the rudder blade sealing plates until the sample boxes are completely matched with the rudder blade sealing plates, and cutting allowance, wherein each rudder blade sealing plate is divided into a middle sealing plate, two lower sealing plates and two upper sealing plates; a platform installation stag:installing the middle sealing plate firstly, then installing the two lower sealing plates through hinges, and then installing the two upper sealing plates through hinges; and a dock installation stage: opening a required rudder blade sealing plate, performing rudder shaft operation, and performing sealing plate assembling and welding operation. The operation safety coefficient on the platform is obviously improved, and a large amount of assembly operation is completed in advance in the platform stage.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to an operation method for moving forward a rudder blade sealing plate. Background technique [0002] When building a bulk carrier, the last construction before undocking is the rudder blade sealing plate. After the whole hull is assembled and welded, the rudder blade is installed through the rudder shaft, and the machine adjustment department tightens the rudder blade with bolts before debugging. After the debugging is completed, the rudder blade can be sealed. There are 5 sealing plates in total. Since the whole operation is under the hull, high cranes cannot be used to hoist the sealing plates. Instead, truck cranes can be used to hoist the rudder blade sealing plates to the corresponding positions, and the assembler then uses a hoist to hang the plates on the rudder blades. , and then slowly carry out a series of operations such as alignment, cutting allowance, installation of seali...
