Description

A cable installation device

The present invention relates to a cable laying apparatus, and more particularly, to a cable laying apparatus in which a cable can be installed using an expansion principle of a stretchable tube having a wrinkle portion.

A large number of cables are installed to supply power to ships or offshore plants or to control the operation of various devices.

Since ships are equipped with various electrical equipments, various types of cables are installed, ranging from low-voltage cables with a small diameter to high-voltage cables with a large diameter.

When installing these cables, install a cable tray in the path of the cables, and lay cables over the trays with a lot of workforce distributed around them.

The cable installation work will be installed several hundred thousand meters depending on the ship type.

The order of laying out the cable on the cable tray usually begins with a "rope installation" to pull the cable in advance within the section to be laid.

As shown in FIG. 1, the rope installation is manually operated by a worker. When the cable is heavy because the weight of the cable is heavy, it is necessary to install the cable in a stranded manner. In order to install a plurality of cables, There is a problem in that the efficiency of the work is reduced because the rope installation work is repeatedly performed.

Particularly, in the case where a cable tray having a different height or a cable tray installed in a vertical direction is required to be installed, the time required for laying the rope occupies a large portion of the entire cable installation work time, resulting in an inefficient operation.

Of course, recently, in order to solve the above-mentioned problem, equipment such as a winch or a cable feeder is used to facilitate installation work.

However, in a place where the equipment is difficult to install or move (such as a narrow area), the equipment is not easy to operate and the cable is damaged.

The object of the present invention is to provide a cable installation device that automates cable installation work but prevents cable damage during installation work.

In order to achieve the above-mentioned object, the present invention provides a method of manufacturing a flexible tube, comprising: a drum wound with a cable; a stretch tube in which a cable is inserted and formed to form a wrinkle to be stretched and shrunk; A retracting tube which is fixed to the fixing chuck through the inside of the stretching tube and retracts the expanded stretch tube to retract the retracted tube, an air pump for expanding the retracted tube by feeding air into the inside of the stretching tube, : Provides a cable laying device comprising:

At this time, it is preferable that the fixing chuck is installed at both ends of the extensible tube.

At this time, the fixing chuck forms a guide hole through which the cable passes to the inside of the extensible tube, and around the guide hole, a supporting member which moves toward the guide hole to support the cable inserted into the guide hole, And a bearing formed on an inner circumferential surface to be formed.

The cable laying apparatus according to the present invention has the following effects.

First, since it is not necessary for the operator to manually unwind the wound cable, it is possible to reduce the number of workings and to prevent the safety accident of the worker.

That is, as the telescopic tube contracted by air jetted from the air pump expands forward and the cable fixed to the end of the expansion / contraction tube advances along the cableway as it goes along the expansion / contraction tube, the cable is easily released from the drum, It can be.

Therefore, the convenience of the installation work can be enhanced and the work productivity can be improved.

Secondly, since the cable is pulled out while the extensible tube is advanced by the air pressure-fed from the air pump, there is no possibility of cable damage occurring.

Therefore, it is effective to reduce the maintenance cost of the cable.

It is to be understood that the words or words used in the present specification and claims are not to be construed in a conventional or dictionary sense and that the inventor can properly define the concept of a term in order to best describe its own design in the best way It should be construed as meaning and concept consistent with the technical idea of the invention.

Hereinafter, a cable installation apparatus according to a preferred embodiment of the present invention will be described with reference to FIGS. 2 to 5 attached hereto.

The cable laying apparatus has a technical feature that it can expand a flexible tube composed of a corrugated tube to lay the cable wound on the drum.

As a result, the productivity of the installation work can be increased by increasing the convenience of the operation, and the maintenance cost can be reduced by preventing the breakage of the cable.

The cable laying apparatus includes a drum 100, an extensible tube 200, a fixing chuck 300, a recovering wire 400, and an air pump 500.

The drum 100 has a structure in which a cable C is wound, and a cable C of several hundred meters or more is wound around the drum 100.

The drum 100 is axially coupled to the support 110 and is rotated so that the cable C wound as the drum 100 is rotated is released.

The expansion and contraction tube 200 plays a role of pulling out the cable C wound on the drum 100 while being inflated by the air ejected by the air pump 500, (Not shown).

The extensible tube 200 forms a corrugation and initially provides a contracted condition as shown in Fig.

The extensible tube 200 may be provided in the so-called bellows type, and its material is preferably provided in polyethylene.

That is, the extensible tube 200 is contracted to the maximum extent as shown in FIG. 2, and is expanded by the air of the air pump 500, and pulls the cable C by the expanding force and moves forward.

Next, the fixing chuck 300 is installed at both ends of the expansion and contraction tube 200 to maintain the airtightness in the expansion and contraction tube 200, and to make the end of the cable C detachable.

That is, the fixing chuck 300 connects the cable C in a state of being fixed to the end of the expansion / contraction tube 200, and pulls out the cable C when the expansion / contraction tube 200 expands.

The fixing chuck 300 serves not only to guide the end of the extensible tube 200 but also to guide the process of winding the cable C wound around the support wall 120 into the extensible tube 200.

A guide hole 310 for guiding the cable C to the extensible tube 200 is formed at the center of the fixing chuck 300 and a support member 320 is installed around the guide hole 310.

A bearing 330 is installed on the inner circumferential surface of the fixing chuck 300 forming the guide hole 310 along the inner circumferential surface.

The diameter of the guide hole 310 is larger than the diameter of the cable C and the support member 320 supports the cable C inserted in the guide hole 310 while moving toward the guide hole 310 .

At this time, the structure of the support member 320 is not limited and may be configured to be movable toward the guide hole 310.

In other words, the fixing chuck 300 is similar to the configuration of a lathe chuck known in the art.

Next, the collection wire 400 serves to return the extensible tube 200 to the original position after the extensible tube 200 is expanded and the cable C is laid, and is disposed at the end of the extensible tube 200 And is fixed to the fixing chuck 300.

One end of the recovering wire 400 is fixed to the fixing chuck 300 and the other end of the recovering wire 400 is connected to a separate winding device (not shown) Respectively.

That is, the winding wire 400 unwound by the operation of the winding machine is wound and the fixing chuck 300 is pulled.

At this time, the winding equipment may be provided separately, but a pulley may be provided on one side of the drum 100 to constitute the winding equipment.

Meanwhile, the material of the recovering wire 400 is not limited, and may be provided as a piano string.

Next, the air pump 500 serves to pressurize air into the extensible tube 200 and includes a hose 510 to which air is supplied.

The air pump 500 is installed on one side of the drum 100.

The air pump 500 is preferably provided with an air booster pump, an air compressor, or the like of a known technology.

Hereinafter, the operation of the cable laying apparatus constructed as described above will be described.

And the drum 100 on which the cable C to be installed is wound is axially coupled to the support base 110.

Next, the support member 320 of the fixing chuck 300 installed on the support wall 120 is opened to open the guide hole 310, the cable C is pushed into the extensible tube 200, and the extensible tube 200 Into the guide hole 310 of the fixing chuck 300 installed at the end of the fixing chuck 300.

The cable C is fixed to the fixing chuck 300 by moving the supporting member 320 of the fixing chuck 300 provided at the end of the extensible tube 200 to hold the cable C .

Next, when the air is injected through the air pump 500, the extensible tube 200 placed on the cableway is expanded by the air pressure to expand along the cableway as shown in FIG.

At this time, the air pressure injected by the air pump 500 is preferably 8 bar, but the air pressure may vary depending on the working conditions.

Since the cable C is fixed to the fixing chuck 300 fixed to the end of the elastic tube 200, the elastic tube 200 is expanded, and at the same time, .

At this time, the recovering wire 400 also unrolls from the winding equipment and goes together.

Next, when the cable installation work is completed, the retractable tube 200 must be returned to its original position, and the supporting member 320 of the fixing chuck 300 fixed to the end of the elastic tube 200 is opened.

As a result, the fixing chuck 300 and the cable C become free from each other.

Next, the winding equipment is operated to wind the recovering wire 400.

At this time, since the collection wire 400 pulls the fixing chuck 300, the expansion and contraction tube 200 is retracted as shown in FIG.

At this time, since the bearing 330 installed on the fixing chuck 300 rolls along the cable C, the recovery process of the elastic tube 200 can be smoothly performed.

As described above, the cable laying apparatus according to the present invention has a technical feature that a cable can be installed using a stretch tube and an air pump.

That is, a bellows-type extensible tube constituting a corrugated part is constituted so that a cable is allowed to flow along an extensible tube by using the principle that the corrugated part of the extensible tube is stretched and restored by air pressure, so that the cable can be easily installed .

Therefore, productivity for cable installation work can be increased, and cable damage can be prevented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
