Description

Technical Field [0001] The present invention relates to a cable installation device for use in a mechanized installation equipment and a construction method of an underground cable,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mechanized installation equipment for an underground cable and a cable installation equipment used in the construction method. More specifically, the present invention relates to a mechanized installation apparatus to which a cable installation apparatus composed of a lift and an under roller is applied.

Generally, a transmission / distribution power cable (hereinafter referred to as a "cable") is installed in a power hole in the ground. In this general installation work (domestic registered Utility Model No. 0263315), as shown in FIG. 1A, a cable 13 wound around a large-sized hub 10 on the ground is supplied into a power port by a laying scaffold 12, The cable 13 in the electric power port was transported along the guide roller 15 while being pulled out by a plurality of fixedly installed caterpillars 14.

1B and 1C, the weight (weight) of the cable 13 is mounted on the fixed caterpillar 14 while the cable 13 is seated on the guide roller 15, The cable 13 is transported along the guide roller 14 by the pulling of the caterpillar 14 and the transported cable 13 is laid on the hanger 16 installed on the power hole wall.

However, in order to transport the heavy cable 13, a large number of the caterpillar 14 and the guide roller 15 must be installed at a short interval, thereby increasing the operation cost. In order to lay the cables 13 transferred in the power sockets on the hangers 16, a large number of workers are arranged in a line and then the cables 13 are lifted up and laid on the hangers 16 Since it was necessary to do the snake work, waste of manpower and manpower was serious. In addition, since the power port is currently manufactured so as to reduce its width while reducing the length of the cable, the installation spacing, the number of installed cables, and the size of the crawler 14 and the guide roller 15 should be taken into consideration in order to install the cable 13, When the power supply line for applying power to the caterpillar 14 is long, the power supply voltage is lowered and power is wasted. . Also, in case of double laying, a large number of caterpillars 14 are required, resulting in an increase in the installation cost.

It is required to develop a cable laying method suitable for the electric power generation environment that is being built as the electric power generation area being built becomes gradually deeper and the length of the cable installation is shortened.

Optimization of the power structure and the enlargement of the cable specification (345 kV, 2,500 mm 2) inevitably lead to a change in the shape of the power sphere and a reduction in the width and a heavy cable.

In addition, the reduction of the power hole width requires the miniaturization and lightening of the cable installation equipment, and the increase in the weight of the cable necessitates a new method for the current workforce-oriented snake operation.

In addition, a method of verifying on-site construction quality will gradually become evident by the extension of the underground transmission construction company.

Therefore, there is a need for a mechanized installation system that eliminates the problem of snake operation by manpower, prevents cable speed, and downtime, and operates it by developing laying equipment and method using rail instead of existing manpower system.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mechanical installation equipment and a construction method of an underground cable to a user.

Specifically, the present invention aims to provide users with mechanized installation equipment and method of underground cables capable of installing cables of all sizes without fluctuation of power sphere width. In the case of the conventional caterpillar laying method, since the caterpillar (width: 700 mm) is installed on the floor of the power hole passage (width: 800 mm), the work passage is narrow (about 100 mm) There was trouble.

12, the under roller 500 proposed by the present invention may include a bearing 501, a tire 502, a chain 503, a speed reducer 504, a motor 505 and a handle 506 have.

Regarding the method of operating the under roller 500, first, the under roller can be positioned on both sides of the drum.

Next, center the tires on both corners of the drum and turn the handles to align the center.

Thereafter, the power is turned on, and the under roller can be operated by using the switch.

When the above-described configuration of the present invention is applied, it is possible to provide a user with a mechanized installation equipment and a construction method of an underground cable capable of installing cables of all sizes without fluctuation of the power sphere width. In the case of the conventional caterpillar laying method, since the caterpillar (width: 700 mm) is installed on the floor of the power hole passage (width: 800 mm), the work passage is narrow (about 100 mm) There was trouble. In the present invention, a cable is installed easily in a narrow electric power area by installing a rail.

In addition, when the configuration of the present invention is applied, a system capable of mechanized installation and snake operation can be provided at all positions where a cable is to be installed. In the conventional caterpillar laying method, first, a cable is laid on the bottom of the electric power source, and then the cable is lifted to a hanger having a height to be constructed. Then arrange the cable and fix the cable. In other words, it takes a lot of manpower and work time to lift the cable after cable installation and it is an inefficient working method. Therefore, in the present invention, there is no step of raising the cable because the rails are installed at the position where the cable is to be installed, and there is no need to raise the cable, and the snake operation is performed by using the snake power truck, .

Further, when the configuration of the present invention is applied, double laying can be made possible. It is possible to install the existing caterpillar by double laying method. However, when the caterpillar is installed for the double laying and the power line is installed more than 1,000m, the number of equipment and the power supply voltage drop frequently occur. In the development method applied to the present invention, a cable is installed on a rail with a cable trailing carriage while extending the length of an inexpensive rail, thereby solving the problem of voltage drop due to the length of a wire for operating a conventional caterpillar, Can be performed more easily. In addition, it is possible to avoid the place where the cable drum can not be installed due to frequent vertical section and traffic volume, so that it is possible to make a long distance double installation.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet) .

In addition, the computer-readable recording medium may be distributed over network-connected computer systems so that computer readable codes can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers of the technical field to which the present invention belongs.

It should be understood that the above-described apparatus and method are not limited to the configuration and method of the embodiments described above, but the embodiments may be modified so that all or some of the embodiments are selectively combined .
