Cylindrical pile leg self-elevating platform jetted pile connector

Abstract

The invention discloses a cylindrical pile leg self-elevating platform jetted pile connector. One end of a hammering union joint serves as a butt welding end and is connected with a jetted pipe in a pile leg in a butt welding mode, and the other end of the hammering union joint serves as an internal thread female hammer union and is connected with a jetted pipe hose and welded to a hole formed inthe wall of the pile leg. The jetted pipe hose is connected with a pile leg jetted pipe connector through a male hammering union with a wing-shaped loose external thread sleeve. The external thread sleeve and the male union can be rotated mutually. It is ensured that the sealing surface cannot rotate relatively in the process of connecting and dismantling the hose. When not in use, the jetted pipeconnector needs to be blocked with a choke plug. The choke plug is composed of two parts, namely, the hex socket external thread head and the male hammering union choke plug which are connected through a screw. The thread head and the choke plug can rotate mutually. It is ensured that the sealing surface cannot rotate relatively in the process of connecting and dismantling the choke plug. A portable pneumatic outer hexagonal wrench can be used for dismounting and mounting the choke plug.

[0002] The cylindrical leg is different from the ordinary triangular truss structure leg. There is a large space between the triangular truss structure leg and the leg surrounding well to arrange the pile interface, and the cylindrical leg and the pile leg surrounding well The gap between them is very small. In order not to affect the normal lifting of the platform, the flushing pile interface can only be designed as an embedded or flush type. Generally speaking, there are currently two types of flushing pile interfaces for cylindrical legs: pile The embedded hole in the leg and the hammer union type and the threaded interface type, the embedded hole in the leg and the hammer union type need to open the embedded hole on the leg, and arrange the punching pile interface in the embedded hole. This type of leg has a large hole, which will affect the strength of the leg. It is necessary to strengthen the hole of the leg, which increases the weight of the platform and reduces the deck load and deck variable load to a certain extent. , and limited by the space, it is very difficult to disassemble and assemble the pile flushing hose during actual operation. The advantage of this type is that the pile flushing interface, the pile flushing hose and the plug are connected by a hammer union, which has high strength and good sealing performance. The connection is reliable; the threaded interface type is made of an internal threaded joint that passes through the wall of the pile leg and is welded with the pile leg. The head is connected by threaded type. Since this type is fastened and sealed by thread, the reliability is not high and the strength is relatively low. Frequent disassembly and assembly for a long time will cause damage to the thread and sealing surface, which is easy to cause leakage. In addition, due to shock The pile interface has been immersed in seawater for a long time, and the traditional thread is very easy to be corroded
