휴대용 전동윈치를 활용한 긴선공법{Electric wire tension method using portable motor operated winch}Electric wire tension method using portable motor operated winch}

본 발명은 휴대용 전동윈치를 활용한 긴선공법에 관한 것으로, 더욱 상세하게는 철탑의 전, 후방휴게소에 경량의 제1, 2전동윈치를 작업자의 작업반경 내에 설치하여 이 제1, 2전동윈치로 1, 2전력선을 끌어당겨 긴선작업을 실시함으로써, 작업자가 작업하고자 하는 의도대로 전동윈치를 조작할 수 있도록 함은 물론, 다른 작업자의 긴선작업과정을 육안으로 확인하거나 의사 소통을 하면서 긴선작업을 할 수 있도록 한 휴대용 전동윈치를 활용한 긴선공법에 관한 것이다.The present invention relates to a long wire method using a portable electric winch, and more particularly to the first and second electric winch by installing light weight first and second electric winches in the working radius of the operator at the front and rear rest areas of the steel tower. By pulling the 1, 2 power lines and carrying out the long wire work, the operator can operate the electric winch as intended, as well as check the communication of other workers with the naked eye or communicate with them. It relates to a long wire method using a portable electric winch that allows.

일반적으로 긴선작업이란, 연선된 전력선을 내장철탑 간에서 소정의 장력으로 인상하여 내장애자장치에 취부하고 현수철탑은 전력선을 현수애자장치에 고정하는 작업을 말한다.In general, the long wire work refers to a task of pulling a stranded power line to a predetermined tension between built-in steel towers and attaching it to a barrier-free device, and a suspended steel tower fixing power lines to a suspension insulator device.

이러한 긴선작업은 도 1에 도시된 바와 같이, 전력선(100)을 애자련(101)과 취부시키기 위해서는 전력선(100)에 캄아롱(CAM-A-LONG)을 위부한 다음 방향전환활차(102)를 거쳐 지상 윈치(103)에서 와이어(104) 당김작업을 하여 이도조정후 전선전달을 하고 애자련(101)에 전력선을 취부하였다.This long-line operation, as shown in Figure 1, in order to mount the power line 100 with the insulator 101, the camber (CAM-A-LONG) on the power line 100 and then turning direction pulley 102 The wire 104 was pulled from the ground winch 103 via the ear canal, and the electric wire was attached to the insulator 101.

그러나 기존의 긴선작업 방법은, 철탑 부지 내 윈치 자리를 선정하여 백호우(Backhoe) 및 인력으로 정지 작업을 한 후 지선근가를 파묻고 원치를 사용하므로 많은 작업시간이 소요됨을 물론, 윈치를 조작하는 1명의 운전원과 인부는 윈치에 감기는 와이어가 엉키지 않게 정리하는 2명의 와이어 정리 인부 등 총 3명의 작업인원이 항시 지상에 상주하면서 와이어 인상작업을 하므로 작업의 효율성이 떨어지는 문제점이 있었다.However, the existing long-line work method selects the winch seat in the site of the steel tower, stops the work by the backhoe and manpower, burys the ground near the ground, and uses the original tool, which takes much time. The operator and the worker has a problem that the efficiency of the work is lowered because a total of three workers, such as two wire cleaning workers to clean up the wires on the winch, always work on the ground and raise the wire.

또한, 윈치 운전원과 송전탑 위에서 긴선작업을 하는 작업자의 거리가 원거리로 있으므로 윈치 조작시 무전기로 교신을 하면서 작업을 해야 하기 때문에 철탑위의 작업자의 안전을 확보하기 어려우며, 윈치의 부피와 무게가 크므로 작업장 부근까지 별도의 윈치 운반차량이 필요하고 윈치 운반에 따른 고가의 비용이 소요되는 문제점이 있었다.In addition, since the distance between the winch operator and the worker who is working on the wireline on the transmission tower is far, it is difficult to secure the safety of the worker on the pylon because the work must be performed while communicating with the radio when operating the winch, and the volume and weight of the winch are large. There is a problem in that a separate winch carrying vehicle is required until the vicinity of the work site, and a high cost of carrying the winch is required.

The fourth step of installing, the fifth step of installing the third turning pulley 13, the sixth step of installing the fourth turning pulley 14, and the cam along (30) on the first power line (1) 7) step of attaching the first power line (1) to the second electric winch (22) to adjust the ear canal, and then cutting the wire and attaching the first power line (1) to the insulator (5); Mount Cam Along (30) on the second power line (2), pull the second power line (2) with the first electric winch (21) to adjust the degree of cut and cut the wire and the second power line to the insulator (5) It consists of the eighth step of attaching (2), specifically When spread as follows:

즉, 제1단계는, 제1방향전환활차(11)를 설치하는 단계로서, 애자련(5)이 위치하는 철탑암(4) 하단에 제1전력선(1)을 끝어당기는 당김와이어(6)가 경유하는 제1방향전환활차(11)를 설치하는 단계이다.That is, the first step is to install the first turning pulley 11, the pulling wire (6) to pull the first power line (1) to the lower end of the pylon arm (4) in which the child training 5 is located It is a step of installing the first direction change pulley (11) via.

상기 제2단계는, 제2방향전환활차(12)를 설치하는 단계로서, 애자련(5)이 위치하는 철탑암(4) 하단에 제2전력선(1)을 끝어당기는 당김와이어(6)가 경유하는 제2방향전환활차(12)를 제1방향전환활차(11)와 마주보도록 나란하게 설치하는 단계이다.The second step is to install the second turning pulley 12, the pulling wire (6) for pulling the second power line (1) to the lower end of the pylon arm (4) in which the child training 5 is located The second turning pulley 12 passing through is a step of installing side by side to face the first turning pulley 11.

상기 제3단계는, 제1전동윈치(21)를 설치하는 단계로서, 애자련(5)이 위치하는 철탑(3)의 네 귀퉁이 중 제1방향전환활차(11)와 대각 방향의 전방철탑휴게소(7) 에 제1전동윈치(21)를 설치하는 단계이다.The third step is the step of installing the first electric winch 21, the front of the iron tower rest of the four corners of the pylon (3) where the child-ryeon (5) is located in front of the iron pylon 11 (7) is the step of installing the first electric winch (21).

이때, 제1전동윈치(21)는 긴선작업 완료 후 다른 작업장소로 이동할 수 있도록 탈부착 가능한 형태로 전방철탑휴게소(7)에 설치한다.At this time, the first electric winch 21 is installed in the front tower rest area (7) in a removable form to move to another work place after the completion of the long wire work.

즉, 전방철탑휴게소(7)에 제1전동윈치(21)를 설치시 고정와이어(9)를 사용하여 제1전동윈치(21)의 후방은 철탑(3)의 귀퉁이 쪽에 설치하고, 고정와이어(9)를 사용하여 당김와이어(6)을 끌어당기는 제1전동윈치(21)의 후방은 철탑(3) 안쪽을 향하도록 설치한다.That is, when the first electric winch 21 is installed at the front pylon resting place 7, the fixed electric wire 9 is used to install the rear of the first electric winch 21 at the corner of the steel tower 3, and the fixed wire ( 9) the rear of the first electric winch 21 for pulling the pull wire 6 is installed to face the inside of the steel tower (3).
