Cable laying equipment used for mechanized laying equipment and construction method of underground cable

The present invention relates to a cable laying equipment used for mechanized laying equipment and construction method of underground cables. Specifically, the present invention relates to a mechanized laying equipment to which a cable laying device composed of a lift and an under roller is applied.

In general, power and distribution power cables (hereinafter referred to as 'cables') are installed in underground power ports. In this general laying operation (Domestic Utility Model No. 0261315), as shown in Fig. 1A, a cable 13 wound on a large hub 10 on the ground is supplied into the power outlet by the installation system 12, The cable 13 in the electric power port was conveyed along the guide roller 15 while being drawn out by a plurality of fixedly installed caterpillars 14.

Here, the transfer of the cable to be described in more detail, as shown in Figure 1b and 1c, the weight (weight) is mounted to the fixed caterpillar 14 is fixed while the cable 13 is seated on the guide roller 15, The cable 13 is conveyed along the guide roller 14 by the traction of the caterpillar 14, and the conveyed cable 13 is installed in the hanger 16 installed on the wall of the power outlet.

However, in order to transport the heavy cable 13, the cost of the work increased because the caterpillar 14 and the guide roller 15 had to be installed at a short interval. In addition, in order to install the cable 13 transferred in the electric power port to the hanger 16, the majority of workers are arranged in a row, and then the cable 13 is lifted and laid on the hanger 16. The waste of manpower and manpower was serious because it had to be snaked afterwards. In addition, since power bulbs are currently manufactured to reduce the width while increasing the length, the installation intervals, the number of installations, and the miniaturization of the caterpillar 14 and the guide roller 15 should be considered in order to install the cable 13, After installation of the cable (13), the work path was narrow, which caused a lot of inconvenience to the transportation of materials and the work of the personnel, and when the power line for supplying power to the caterpillar (14) was long, the power voltage was lowered, resulting in power wastage. . In addition, in the case of double laying, a large number of caterpillars 14 are required, and there is a problem that the use of the raising equipment increases.

As the electric power cords are being deepened and cable laying sections are lengthened, the cable laying method suitable for the electric power cord environment is required.

Optimizing the power port structure and increasing the size of the cable specification (345㎸ 2500mm) inevitably leads to a change in the shape of the power cord, a reduction in the width, and a high weight of the cable.

In addition, the reduction of the power sphere width requires miniaturization and lightening of the cable laying equipment, and the high weight of the cable requires a new method for the current manpower-oriented snake work.

In addition, as the underground transmission construction company expands, the verification method of site construction quality will gradually emerge.

Therefore, there is a demand for a mechanized laying system that eliminates the problem of snake work by manpower and prevents and operates cable speed and distortion by developing laying equipment and construction methods using rails instead of the existing manpower method.

The present invention has been made to solve the conventional problems as described above, the object is to provide a mechanized installation equipment and construction method of underground cable to the user.

Specifically, the present invention is intended to provide a user with a mechanized installation equipment and construction method of underground cable capable of laying cables of all specifications without changing the power sphere width. In the existing caterpillar installation method, the caterpillar (width: 700mm) is installed on the floor of the power outlet passage (width: 800mm), so that the work path is narrow (about 100mm), so it is difficult to transport materials and There was a problem. In the present invention, a cable is easily installed even in a narrow power port by installing a rail.

In addition, the present invention is to provide a system capable of mechanized installation and snake work in any position to install the cable. In the existing caterpillar installation method, the cable is first installed at the bottom of a power outlet, and then the cable is lifted to a hanger having a height to be constructed. After arranging the cables, fix the cables. In other words, it takes a lot of manpower and work time to lift the cable after the cable is laid and is an inefficient work method. Therefore, in the present invention, since the rail is installed directly at the position where the cable is to be installed, the cable is not directly lifted, and there is no process of lifting the cable. To provide.

The present invention further aims to enable double laying. Double laying refers to laying that includes sections that only pull the cable because the cable installation position is different from the cable laying position. The existing caterpillar laying method is also possible to install the double, but the installation of the caterpillar for the double laying, if the power line is installed more than 1,000m, problems such as excessive quantity of equipment, power supply voltage drop frequently occurred. In the development method applied to the present invention, by installing the cable in the cable towing bogie on the rail while only extending the length of the cheap rail, problems such as voltage drop along the length of the wire for operating the conventional caterpillar are eliminated and long distance installation This can be done much easier. In addition, since it is possible to install the vertical sphere section and the traffic volume to avoid the place where the cable drum can not be installed, long distance double laying can be possible.

After that, the lifter may be leveled using the auxiliary support and then supported by the fixed support.

In addition, after the power is turned on, the lift height can be adjusted to suit the work site by using a switch.

Then, the height and length of the inlet roller slide and the horizontal roller slide according to the caterpillar, and can be used by using a switch when using the winch.

On the other hand, the underroller 500 shown on the right side of Figure 8 is used for the purpose of using when the cable is removed or wound on the drum.

In detail, the underroller 500 may freely unwind and wind using a switch.

In addition, the under-roller 500 according to the present invention has the advantage that the stability is good close to the ground during the operation, light weight is easy to move and install.

However, the content of the specification shown in FIG. 11 is merely an example that can be applied to the present invention, and the content of the present invention is not limited thereto.

In addition, Figure 12 illustrates in detail the components of the under roller in connection with the present invention.

Referring to FIG. 12, the underroller 500 proposed by the present invention may include a bearing 501, a tire 502, a chain 503, a reducer 504, a motor 505, and a handle 506. have.

Regarding the operation method of the underroller 500, first, the underroller can be positioned on both sides of the drum.

Next, the center of the tire is positioned at both corners of the drum and the handle can be turned to center it.

After that, turn on the power and use the switch to operate the underroller.

When the above-described configuration of the present invention is applied, the mechanized laying equipment and the construction method of the underground cable capable of laying cables of any standard without changing the power sphere width can be provided to the user. In the existing caterpillar installation method, the caterpillar (width: 700mm) is installed on the floor of the power outlet passage (width: 800mm), so that the work path is narrow (about 100mm), so it is difficult to transport materials and There was a problem. In the present invention, a cable is easily installed even in a narrow power port by installing a rail.

In addition, when the configuration of the present invention is applied, a system capable of mechanized laying and snake work can be provided at all positions where the cable is to be installed. In the existing caterpillar installation method, the cable is first installed at the bottom of a power outlet, and then the cable is lifted to a hanger having a height to be constructed. After arranging the cables, fix the cables. In other words, it takes a lot of manpower and work time to lift the cable after the cable is laid and is an inefficient work method. Therefore, in the present invention, since the rail is installed directly at the position where the cable is to be installed, the cable is not directly lifted, and there is no process of lifting the cable. To provide.

Furthermore, when the configuration of the present invention is applied, double laying may be possible. The existing caterpillar laying method is also possible to install the double, but the installation of the caterpillar for the double laying, if the power line is installed more than 1,000m, problems such as excessive quantity of equipment, power supply voltage drop frequently occurred. In the development method applied to the present invention, by installing the cable in the cable towing bogie on the rail while only extending the length of the cheap rail, problems such as voltage drop along the length of the wire for operating the conventional caterpillar are eliminated and long distance installation This can be done much easier. In addition, since it is possible to install the vertical sphere section and the traffic volume to avoid the place where the cable drum can not be installed, long distance double laying can be possible.

On the other hand, the present invention can also be embodied as computer readable codes on a computer readable recording medium. Computer-readable recording media include all kinds of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, which are also implemented in the form of carrier waves (for example, transmission over the Internet). Include.

The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.

In addition, the above-described apparatus and method may not be limitedly applied to the configuration and method of the above-described embodiments, but the embodiments may be selectively combined in whole or in part in each of the embodiments so that various modifications may be made. It may be configured.
