Bow blowing spherical joint of dredging ship

Abstract

The invention discloses a dredger bow-blowing spherical joint. The dredger bow-blowing spherical joint comprises a female joint and a male joint, wherein the female joint and the male joint are mutually matched and connected; the female joint comprises a connecting pipe, wherein the bottom of the connecting pipe is connected with a female sleeve head, and the female sleeve head is provided with a locking device used for locking the male joint; the male joint comprises an upper cover, a lower cover and a sphere connecting pipe, wherein the sphere connecting pipe is arranged between the upper cover and the lower cover, the upper portion of the sphere connecting pipe is provided with a spherical rotation part, the inner wall of the upper cover and the inner wall of the lower cover are circular arcs matched with the surface of the spherical rotation part, and the spherical rotation part can be limited by the upper cover and the lower cover to rotate and swing. The dredger bow-blowing spherical joint is easy and convenient to install, so that disassembly efficiency and assembly efficiency are improved; the spherical rotation part can rotate and swing relative to the upper cover and the lower cover so as to be adapted to irregular swings of a dredger floating on the water surface, and the dredger bow-blowing spherical joint is prevented from damage caused by swings of dredge pipes.

Description

technical field [0001] The invention relates to a pipe joint for dredging bow blowing, in particular to a dredging bow blowing spherical joint. Background technique [0002] Existing trailing suction dredgers need to pump the mud into the mud tank through the trailing suction pipe when dredging, and discharge the mud after arriving at the destination. The way of mud discharge plays an increasingly important role in trailing suction dredgers. [0003] When the bow is blowing, the mud discharge floating pipe on the water surface is connected to the discharge pipe at the bow of the dredger, and the mud is discharged to the shore through the pipe. Some joints currently used take a long time to connect. If the key connecting steel strip is damaged, the joint can hardly work, and it is difficult to replace the spare parts. The male head used has been soaked in seawater for a long time, and there is no sealing ring inside itself. The lubricating oil injected is basically invalid ...

Problems solved by technology

Some joints currently used take a long time to connect. If the key connecting steel strip is damaged, the joint can hardly work, and it is difficult to replace spare parts.

The male head used has been soaked in seawater for a long time, and there is no sealing ring inside itself. The lubricating oil injected is basically invalid after one use, and sand is easy to enter the mating surface during use, which will accelerate the wear of parts
