AI Technical Summary

Problems solved by technology

In particular, motors are a cause of failure, especially when used in drive systems below the waterline, where they are more susceptible to damage due to leaks
These failures cause the motor to be repaired or replaced
However, servicing motors requires specialized tools, especially trained personnel and specialized equipment
Maintenance equipment carried with dredging units is often limited and unsuitable for these repairs, meaning the motor in question needs to be shipped in for repair and a replacement motor used, resulting in downtime for the dredger

Embodiment Construction

[0023] figure 1 The propeller dredger shown comprises a floating body 1 carrying a suction pipe arrangement 2 . The suction pipe device 2 is installed on the floating main body 1 through a hinge 4, and can be placed in a working position (such as figure 1 shown) and the horizontal rest position. The suction pipe device 2 has a cutting head 6 which cuts the substance of the bottom 7 of a body of water 8 .

[0024] figure 2 An enlarged view of the pipette device is shown. The straw arrangement comprises a frame 9 and several other elements supported on said frame. At one end of said frame 9 the cutting head 6 is rotatable about an axis 10 . The cutting head is connected to a cutting head drive system 11 comprising an electric motor 12 and a shaft 13 . In this embodiment one electric motor 12 is shown, but the cutting head drive system 11 could also use multiple motors. The cutting head drive system 11 may include submersible transmissions to accommodate differences in th...

Abstract

The invention relates to suction tube device provided with drive systems and method of repairing same, the suction tube device comprising a frame, a tube, a centrifugal pump which cooperates with the tube and a cutter head at one end of the tube, said tube, centrifugal pump and cutter head being supported by the frame, said centrifugal pump and said cutter head each being provided with a drive system, the drive systems of the centrifugal pump and of the cutter head each comprising at least one motor, wherein a motor of the drive system of the cutter head and a motor of the drive system of the centrifugal pump are interchangeable with respect to each other.

Description

technical field [0001] The invention relates to a suction pipe device comprising a frame, a pipe, a rotary cutting device at one end of said pipe and a centrifugal pump cooperating with the pipe, said pipe, centrifugal pump and rotary cutting device being supported by said frame, the Both the centrifugal pump and the rotary cutting device are provided with a drive system having at least one motor. Background technique [0002] As we all know, the suction pipe device is applied to the suction dredger, and the dredged material can be dug out from the bottom of the water body, and transported to the treatment site or the mud tank ship through the floating pipeline. These jobs are often performed in remote locations and over long periods of time. From this point of view, it is very important to ensure that the work is not hindered by the failure of mechanical and electronic components. [0003] Nevertheless, the dredging process is often interrupted due to the drive system. I...
