A swash plate drum cable laying machine

Abstract

The invention discloses a reel cable-laying machine of an inclined disc type, and the reel cable-laying machine comprises an inclined disc type drum wheel machine which is disposed on a laying ship; and a combined tyre machine which is disposed at a lower work position of the inclined disc type drum wheel machine. The inclined disc type drum wheel machine is driven to operate through three motors. A motor control cabinet comprises a PLC, three frequency converters, and three braking resistors. The PLC is connected with the three frequency converters, and each frequency converter is connected with one braking resistor and one motor. An industrial computer is connected with the PLC, and the PLC is controlled through the industrial computer. Sensors are used for detecting the rotating speeds, torques and cable laying lengths of three motors, and are connected with the PLC. The reel cable-laying machine also comprises a GPS navigator which is connected with the industrial computer. The reel cable-laying machine avoids the manual operation of a cable sorting knife of a cable-laying machine, achieves a purpose of automatically sorting the marine cables on a reel, and guarantees the safety of the cables. The reel cable-laying machine employs the technologies of frequency conversion and computer control, achieves the automatic response and precise control in the construction process of a deep seat cable, employs a mode of electric dragging, and facilitates the conveying and modular installation.

Description

technical field [0001] The invention relates to the technical field of cable laying machines, in particular to a swash plate type drum cable laying machine. Background technique [0002] At present, the method of forced combing of submarine cables by the splitting knife process used by drum cable laying machines is extremely unsafe: when laying or salvaging deep-sea submarine cables, in order to obtain sufficient traction or braking force for submarine cables, it is usually Several turns are helically wound on a cylindrical reel with a diameter of about 3m. During salvage or laying operations, as the drum rotates, the submarine cable is continuously laid out, and the spirally wound cable will also move along the axial direction of the drum. When it is blocked by the wall plate on one side of the drum , The cables will overlap and cross here, which will cause the construction to be suspended, and serious quality accidents will occur. [0003] In order to prevent this situat...

Problems solved by technology

However, the control method using hydraulic drive to rotate the reel is realized by adjusting the opening of the valve. It is an analog control, and it is difficult to achieve automatic response and precise control.

[0005] Due to the large structure and dimensions of the reel cable laying machine, and the existence of supporting facilities such as hydraulic stations, various hydraulic pipelines and valves are even more intricate.

Therefore, the drum turbine driven by this type is limited to being permanently fixed on a ship, and cannot be disassembled, transported and installed in a modular manner
