Description

Winch for laying coupling transmission steel cable

Technical Field

The utility model belongs to the technical field of deep sea cable is laid, concretely relates to winch is put to laying of transmission steel cable.

Background

Inductive coupling transmission is an effective means for underwater data transmission and is widely used by professional technicians, however, the deep sea plastic-coated steel cable is long and heavy, and the arrangement of the deep sea plastic-coated steel cable is always difficult. At present, no special equipment is arranged for laying the deep sea plastic-coated steel cable, and the device is a special utility model for solving the problem.

At present, the laying of the deep sea plastic-coated steel cable is generally to wind the plastic-coated steel cable on a common winch, and when the plastic-coated steel cable is about to be released, about 10 meters of the steel cable are left. And stopping the winch and connecting the butt-joint cable. The coated wire rope and cable splice then pass through the winch drum together, which can present a jamming problem due to the large and difficult passage of the coated wire rope and cable splice through the drum.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned problem of existence is put to the cloth of conventional deep sea plastic-coated steel cable, the utility model provides a winch is put to cloth of coupling transmission steel cable.

The utility model provides a technical scheme that its technical problem adopted is: the laying winch comprises a winch drum, wherein a partition board is arranged on the winch drum and divides the drum into two areas.

As an optimized mode of the present invention, the partition board is provided with a notch or a via hole for the cable to pass through.

Further preferably, one of the regions of the drum is provided with a fixing member.

Further preferably, a steel wire rope is wound in one of the areas, one end of the steel wire rope is fixed on the winch drum through the fixing part, and the other end of the steel wire rope is connected with the plastic-coated steel wire rope.

Further preferably, the length of the steel wire rope is 10-20 meters.

The utility model provides a winch is put to cloth, the beneficial effect who has is: the common winch drum is divided into two areas, so that the plastic-coated steel cable can be guaranteed to be arranged neatly and not to be damaged; the plastic-coated steel cable is lifted and is connected with a section of force-bearing steel cable, when the plastic-coated steel cable is completely released, the plastic-coated steel cable can be pulled by the steel cable which is connected in advance, the butt-joint cable rope is not stressed when being connected with the plastic-coated steel cable and is easy to connect, after the cylinder is rotated again to release the common steel cable, the plastic-coated steel cable can be pulled by the butt-joint cable rope (the butt-joint cable rope is fixed on a mooring bollard which is laid on a ship in advance), and the common steel cable rope is connected with the plastic-coated steel cable and is not stressed and is easy to remove. The deep-sea plastic-coated steel cable is laid by the winch, the laying of the winch can be controlled at any time, and equipment on the plastic-coated steel cable is convenient to install.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

The embodiment provides a laying winch coupled with a transmission steel cable, which has a structure shown in fig. 1 and comprises a winch frame 1, a winch drum 2 and a drum bearing 3. As shown in fig. 2 and 3, a partition plate 4 is provided on the winch drum 2, and the winch drum is divided into two large and small areas by the partition plate 4. Wherein the larger area is used for winding the plastic coated steel cable 8, and the smaller area is used for winding the common steel cable 7. And the common steel wire rope 7 is connected with the plastic-coated steel wire rope 8 through a shackle.

A recess 6 is provided in the partition 4, which recess 6 is used for the passage of the cable. And a pressing block 5 is arranged outside the area where the common steel wire rope 7 is wound, and is used for fixing the starting end of the common steel wire rope 7.

The plastic-coated steel cable laying method is characterized in that the plastic-coated steel cable is laid by adopting the laying cable car in the embodiment, and the concrete steps are as follows:

firstly, a plastic-coated steel cable 8 is connected with a common steel cable 7 through a shackle, the common steel cable is generally 15 meters, the other end of the common steel cable 7 is fixed on a winch drum 2 through a pressing block 5, then the common steel cable 7 is wound in a smaller area on one side of a partition plate 4 until the common steel cable 7 is completely wound, 0.5-1 meter more plastic-coated steel cable 8 is wound, and then the plastic-coated steel cable 8 is wound in the area on the other side of the partition plate 4 through a gap 6.

When the steel cable 8 coated with the plastic is laid, the steel cable 8 coated with the plastic is released through the laying winch until the steel cable 8 coated with the plastic is completely released, the butt-joint shackle of the steel cable 8 coated with the plastic is exposed, as shown in fig. 4, the butt-joint cable 9 is wound on a mooring bollard of the laying ship, then the butt-joint cable shackle is connected with the shackle of the steel cable 8 coated with the plastic, the common steel cable 7 is continuously released through the laying winch after the connection is finished until the steel cable is free from stress, the steel cable 8 coated with the plastic is pulled by the butt-joint cable 9, then the connection shackle of the common steel cable 7 and the steel cable 8 coated with the plastic is removed, the butt-joint cable 9 is slowly released, and the laying of the steel cable coated with the plastic is finished.
