Description
Technical Field
The invention relates to the technical field of crown plate prefabrication, in particular to a prefabrication process of a king pile type jacket crown plate.
Background
The jacket platform is a structure fixed to the seabed by steel piles through a jacket, and the jacket itself has sufficient rigidity to ensure the structural integrity of the platform. The jacket platform is divided into a main pile type jacket and a skirt type jacket. The main pile type guide pipe frame is formed by directly driving a steel pile into water through a main guide pipe, and the skirt type guide pipe frame is formed by driving the steel pile into water through skirt sleeves around a platform. The welding fixation of the outer sleeve at the top of the guide pipe of the main pile type guide pipe frame and the steel pile driven into the guide pipe is realized through the crown plate. The crown plate is similar to a crown-shaped arc-shaped steel plate as the name implies, a single arc-shaped bent special-shaped steel plate with a Mongolian section shape is usually arranged at certain intervals, and the complete crown plate is formed by the special-shaped steel plates.
At present, the crown plate is mainly prefabricated by two methods, namely firstly, typesetting and cutting are carried out, and then, a rolling arc is pressed and formed; secondly, typesetting and rolling the materials firstly, and then cutting and forming the handle.
The first method comprises the following steps: typesetting, namely, firstly, reserving blank pressing allowance for the crown plates when the plates are typeset, wherein six crown plates are arranged in a single row, and all the crown plates are arranged on the same steel plate; blanking by using a numerical control plate cutting machine; and then a single crown plate of a press machine is used for pressing a bend with a corresponding radian, and then the blank pressing excess material is cut off for molding.
The second method comprises the following steps: typesetting, namely arranging six crown plate plates in a single row, wherein all the crown plate plates are arranged on the same steel plate; rolling the whole plate into a circular tube by using a plate rolling machine, and then cutting the crown plates in a single row and a row to form a plurality of rolled single tubes with the width of about 400 mm; and covering the steel pipe rolled in the circumferential direction by using the template which is manufactured by lofting, and then cutting and forming the steel pipe along the handle at the edge of the template by a worker.
The crown plate prefabricating process has the following defects: the main disadvantages of the first method are: although the blanking precision of the numerical control plate cutting machine used for blanking is high, the size of the crown plate is small, the press machine used in the next process needs to be repeatedly bent and measured, the requirement on corresponding radian can be met, the prefabrication time is long, more labor is consumed, the forming precision is not high, the blank pressing allowance reserved in advance still needs to be cut after the plate is pressed into an arc shape, and the material utilization rate is low. The main disadvantages of the second method are: the height of the crown plate is generally small and is only about 400mm, the width of the magnetic cutting machine with the auxiliary tool reaches more than 500mm, the magnetic cutting machine is not suitable for cutting the crown plate, a handle is usually used for cutting, the molded appearance of the crown plate cut by the handle is not good, and the cutting precision and quality are poor. The crown plates are arranged in a single row, so that the condition of steel waste exists, more cutting waste materials exist, and the cutting amount is larger. Before the cutting is carried out by the handle, a 1:1 crown-shaped sample plate needs to be manufactured by independent lofting, the preparation time for cutting the crown plate is long, and the cutting operation efficiency is low.
In summary, the prior art of prefabricating crown plates has the problems of low material utilization rate, poor appearance after molding and low operation efficiency.
