Description

Customized braket module for cable transfer module used in underground power cable installation}

In the construction of installing power cables for transmission and distribution in an underground power outlet, the present invention is a bracket module for custom-made installation of a cable transport module that can be connected or arranged in multiple ways according to the construction environment in a hanger type provided in the power outlet, and It is about the construction method using it.

Cable undergrounding refers to laying transmission and distribution lines underground using pipes or utility tunnels. This is mainly aimed at improving the aesthetics of the city, the safety of citizens, and preventing power outages due to weather.

Such cable undergrounding generally consists of a process in which cables wound on drums are supplied into power outlets through laying scaffolding and pulling equipment, and the supplied cables are laid while being guided by a plurality of pulling devices and guide rollers in the power outlet.

Here, the length of the normal laying section is about 500 m, which can be defined as a "unit process section". Cables transported in a unit process section and cables transported in a neighboring unit process section are connected by a connector, so long-distance installation can be achieved.

On the other hand, pulling equipment used for cable undergrounding may be classified as pressurized pulling equipment or towed pulling equipment.

First, as pressure-type pulling equipment, there are also tire-type or caterpillar-type feeders, guide rollers, and winches. A plurality of each equipment may be installed at predetermined intervals on the bottom surface of the power outlet according to the geographical environment.

The feeder is used to stably transport the cable to a long distance, and a high-power product of about 800W and a high-weight product are usually used.

Therefore, there is a problem in that it is dangerous and time-consuming to transport a heavy feeder product into an electric power outlet through an entrance such as a manhole.

In addition, there is a difficulty in laying a heavy weight and long length of cable during the cable pulling operation. That is, since high-voltage or low-voltage transmission and distribution power cables typically have a maximum length of 500 to 600 m and a weight of 20 to 30 tons, a lot of traction force is required.

Furthermore, even after a cable transporting means such as a high-power feeder is installed, it is bulky and considerably obstructs the movement of workers into a narrow space formed between the feeder and the power outlet, thereby reducing work efficiency.

On the other hand, in the case of traction pulling equipment, a rail is laid in a power outlet, and the cable is transported by a self-propelled tow truck and a support truck moving along the rail.

The self-propelled tow truck pulls the front end of the cable, and the support truck moves along the rail while supporting the cable while maintaining a certain distance from the tow truck.

On the other hand, the bogie as described above is also a type that runs on the bottom surface of the electric power outlet instead of the rail.

These bogies are provided with considerable weight. Therefore, in order for the bogie to run on the rail, the rail must be prepared to bear the weight of the bogie and the weight of the cables.

For example, additional equipment elements are generated, such as reinforcing the angle of a wall within a power outlet or constructing a floor wide enough for a tow truck to run, and accordingly, additional transport elements are generated.

In addition, since these rails are manufactured in a rectangular cross-sectional shape with gears processed on the lower surface, there is also a processing difficulty in that they must be bent to fit the power tool in the bending section.

Next, after the cable is transported, an operation of transferring and fixing the transported cable to the hanger installed on the wall of the power outlet is performed.

Since the cable transfer work must be repeated as much as the laid distance, a large number of manpower or work time is required. In addition, the entire laid cable caused musculoskeletal disorders of working personnel as an ultra-high load.

As devised to solve this problem, a method of reducing the vertical movement distance of the load by installing a pulling device at a height corresponding to the height of the hanger has been proposed.

That is, it is necessary to install a transport means such as a feeder at an elevated height, and when attempting to install a transport means having a high weight, there is a problem in that equipment reinforcement capable of supporting the weight is additionally required.

In addition, compared to the case of installing on the floor, a phenomenon in which the cable is sagging between the transfer means occurs. Therefore, it is necessary to install the transportation means at a narrower interval, and accordingly, reinforcement of facilities has been additionally required.

As devised to solve this problem, a method of installing the rail at a height corresponding to the height of the hanger has been proposed.

As shown in the straight section (a) of FIG. 1, a plurality of anchors 20 may be installed at predetermined intervals in the electric power outlet 10 consisting of a plurality of unit process sections (d).

A hanger 30 for seating the transported cable 40 may be installed in the anchor 20 .

A conveying means 300 composed of a feeder 50, a roller 340, and a winch 310 may be disposed on the bottom surface of the power tool 10.

As an embodiment of the transfer means 300, large feeders 50 may be disposed at a first interval e with three anchors 20 interposed therebetween. The large feeder 50 may generally be classified as a product having specifications of 800W or more.

Next, one or more rollers 340 may be installed on the path where the large feeder 50 is installed.

In addition, the winch 310 may be installed in the end section of the unit process section (d).

The winch rope 320 connected to the winch 310 is connected to the front end 41 of the cable and pulls the cable 40 with a predetermined force to assist in stable transfer.

Here, when transferring the transported cable 40 to the hanger 30, the transfer operation is very inefficient because the vertical distance g defined as the distance from the transport means 300 to the hanger 30 is long. It is done.

In addition, in the slope section (b), there is a risk of damage to the cable 40 in the section where the tension increases. This slope section (b) can be divided into a downward conveying section (b-1) and an upward conveying section (b-2).

In particular, the tension applied to the cable 40 increases rapidly in a section from the downward conveying section (b-1) to the upward conveying section (b-2), so that the risk of damage to the cable 40 may increase.

7 is a flow chart showing a method of constructing an underground cable using a customized multi-connection transfer device according to the present invention.

The installation method for underground power cable using customized multi-coupled transfer equipment (hereinafter referred to as "C.M.T method") is a support structure installation step (S100), a plate installation step ( S200), conveying means installation step (S300), rope conveying step (S400), cable-rope coupling step (S500), cable conveying step (S600), cable transfer step (S700).

First, in the support structure installation step (S100), as shown in FIG. 3, the support structure 100 is installed at a position (X) spaced apart from the hanger 30 by a predetermined distance.

The support structure 100 may be installed parallel to the anchor 20 .

The support structure 100 may have a pillar shape.

The support structure 100 may have a form in which both sides are fixed to the ceiling and floor surfaces of the power outlet 10 and stand upright.

As shown in FIGS. 3, 4 and 5, the support structure 100 may be installed in a number corresponding to all anchors 20 and hangers 30.

In addition, it is preferable to be installed at a position spaced apart from the end of the hanger 30 by a predetermined distance.

However, it does not mean that the installation location and number of the support structure 100 are limited, and when the load is concentrated and reinforcement is required, additional installation may be performed, and in the opposite case, fewer installations may be performed.

Next, in the plate installation step (S200), the plate 200 is installed at a position spaced a predetermined distance from the bottom surface of the power outlet 10.

The plate 200 is for installing the transfer means 300 on the upper surface.

The plate 200 may be provided and fixed between the hanger 30 and the support structure 100 .

In addition, the plate 200 may be provided and fixed between the supporting structure 100 and the neighboring supporting structure 100 .

The location or number at which the plates 200 are installed may correspond to the location or number at which the transfer means 300 are installed.

The size or properties of the plate 200 may be provided so that it can be stably supported according to the type of the transport means 300 .

Next, in the conveying means installation step (S300), the conveying means 300 including the winch 310, the feeder 330, or the roller 340 is installed on the plurality of plates 200.

Here, the feeder 330 is provided in a small size and is easy to install one or more on the plate 200 .

The small feeder 330 may be classified as a product having specifications ranging from 200W to 300W, but is not meant to be limited to one type having specific specifications.

In addition, the winch 310 may be installed in the end section of the unit process section (d).

Next, in the rope transfer step (S400), the rope 320 is transferred by the winch 310, and in the cable-rope coupling step (S500), the rope 320 is attached to the front end 41 of the cable. connect In the cable transfer step (S600), the cable 40 is transferred while interlockingly controlling the winch 310 and the feeder 330.

Therefore, in the step of adjusting the angle of the unit plate (S211), the plurality of unit plates 210 may naturally form a curved shape due to the influence of gravity in the inclined section (b).

When the cable 40 is transported, tension is generated and the plate 200 is shaken. Therefore, the first adjustment unit 220 is fixed before transport to form a plurality of unit plates 210 into one rigid body. should be formed with

The first adjustment unit 220 may further include an angle fixing unit.

Therefore, in the unit plate angle fixing step ( S212 ), the curved shape formed by the unit plate 210 may be fixed.

Through this, the transfer means 300 coupled to the unit plate 210 is installed at a fixed angle so that the cable 40 is accurately transferred along the inclined section (b). can

As shown in FIG. 6 , the plate 200 may further include a second adjustment means 230 for adjusting and fixing the installation angle of the winch 310, the roller 340, or the feeder 330.

As shown in FIGS. 3 and 6 , the second adjusting unit 230 may be a groove formed on an upper surface of the plate 200 .

A tolerance may be formed in the groove to be spaced apart by a predetermined interval in the left and right directions when the conveying means 300 is coupled.

Here, as shown in FIG. 6 , the second angle adjusting step ( S320 ) may further include a conveying means angle adjusting step ( S321 ) and a conveying means angle fixing step ( S322 ).

The conveying means 300 is coupled to the second adjusting means 230, and can be rotated left and right within tolerance, so that the installation angle can be adjusted so that the cable 40 can be accurately conveyed along the curved shape in the curved section. .

When the cable 40 is transported, tension is generated and the transport unit 300 is shaken. Therefore, the transport unit 300 and the plate 200 are united by fixing the second adjustment unit 230 before transport. It should be formed as a rigid body.

The second adjusting unit 230 may further include an angle fixing unit.

Therefore, in the step of fixing the angle of the transfer unit ( S322 ), the installation angle of the transfer unit 300 may be fixed.

Through this, the transfer means 300 coupled to the plate 200 can accurately transfer the cable 40 along the inclined section (b) or the curved section.

Taken together, in the tension increasing section, the feeder 330 may be intensively placed or the installation angle may be adjusted. Conversely, in a tension reduction section requiring a low load, the small feeder 330 replacing the large feeder 50 may be disposed.

The feeder 330 or the unit plate 210 is not only easy to transport and install, but also increases efficiency of the transfer of the cable 40 and prevents injury to the musculoskeletal system of workers.

Therefore, there is an effect of ultimately increasing energy efficiency by reducing the total power consumption in the unit process section (d) as a whole.
