Method for butting flange faces by using butting device

Abstract

The invention belongs to the technical field of machinery installation equipment, and relates to a butting method in order to solve the problems of difficult equipment alignment, low installation efficiency and incidental member collision damage due to the influence of wind waves when large engineering equipment are hoisted on the sea. The invention provides a method for butting flange faces by using a butting device. The method comprises the following steps of: making one end of a butting rope pass through a fixed seat along a positioning pipe and a central hole, and fixedly connecting the butting rope on the fixed seat through the positioning pipe and the central hole; inserting a guide pin section of the positioning pipe into a mounting hole of a first flange face by the guide of the butting rope; and making the butting rope pass through a mounting hole corresponding to the mounting hole of the first flange face and positioned on a second flange face, making the guide pin section pass through the mounting hole positioned on the second flange face, then pulling the butting rope by using a braking device, and finally butting the first flange face and the second flange face. The method can effectively solve the technical problems.

Description

technical field [0001] The invention belongs to the technical field of mechanical installation equipment, and relates to a butt joint method, in particular to a method for butt joint flange faces using a butt joint device. Background technique [0002] The installation of large-scale engineering equipment at sea is generally completed by hoisting. Compared with hoisting on land, due to the influence of wind and waves during hoisting at sea, the hoisting hull fluctuates and rolls sideways. to a larger swing. As a result, alignment is difficult during hoisting, installation efficiency is low, and collision damage to components is prone to occur. For example, in the split installation of offshore wind turbines, the hub and blades are often assembled on the ground before the components are hoisted to the installed nacelle superior. At this time, the docking of the nacelle and the straight flange surface of the hub is completed at high altitude. The effects of wind and waves m...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that due to the influence of wind and waves when hoisting large-scale engineering equipment at sea, the alignment of equipment is difficult, the installation efficiency is low, and the collision damage of components is prone to occur, and a docking method is provided to solve this problem. This method can also be applied to hoisting large equipment in environments similar to offshore environments, such as deserts with strong wind and sand, etc.
