Description

  The present invention relates to a power transmission line inspection system in which a traveling vehicle equipped with a camera is installed on a steel tower, and the inspection device composed of the traveling vehicle and the camera is remotely operated by an operation device to inspect the transmission line.

  Traditionally, transmission lines installed on steel towers have been inspected by inspectors ascending to the steel tower and observing them visually. However, this is a work that involves danger such as a crash or electric shock. Since accidents have also occurred, inspections have started using a transmission line inspection system that can be inspected remotely.

  As this power transmission line inspection system, for example, as disclosed in Patent Document 1, an inspection device in which a camera is mounted on a traveling vehicle that moves up and down a steel tower is remotely operated by an operation device installed at a remote location. What has been devised.

  In this transmission line inspection system, a dedicated rail is newly installed on the steel tower, a traveling vehicle is installed on the rail, a camera is mounted on the traveling vehicle via a movable head, and the traveling of the traveling vehicle is operated from the operating device. Instead, the camera is operated to move the field of view of the camera to shoot various images.

  However, in the conventional power transmission line inspection system, it is necessary to newly install a dedicated rail on the steel tower, and the initial capital investment is large.

  Further, in the conventional power transmission line inspection system, it is necessary to operate the movable pan head to capture images viewed from various viewpoints, and the operation with the operation device becomes complicated.

  Therefore, in the present invention according to claim 1, a traveling vehicle equipped with a camera is installed on a steel tower, and a power transmission line inspection is performed by remotely operating an inspection device composed of the traveling vehicle and the camera with an operation device. In the system, a traveling vehicle is installed on a guide rail for preventing a fall along an ascending pillar of a steel tower so that the traveling vehicle can be moved up and down, and a camera capable of photographing at a hemispherical viewing angle is mounted on the upper end of the traveling vehicle, The hemispherical viewing angle image captured by the camera is configured to be transmitted from the inspection device to the operation device.

  Further, in the present invention according to claim 2, in the present invention according to claim 1, an arm that swings in a range wider than the lateral width of the climbing column is provided at the upper end of the traveling vehicle, and a camera is mounted on the arm. I decided to install it.

  And in this invention, there exists an effect described below.

  That is, in the present invention, in a transmission line inspection system that installs a traveling vehicle equipped with a camera on a steel tower and remotely inspects the inspection device composed of the traveling vehicle and the camera with an operation device, A hemisphere photographed with a camera equipped with a camera that can be taken with a hemispherical viewing angle on the upper end of the traveling car, installed on a guide rail for preventing crashing along the climbing column Since an image of a viewing angle is transmitted from the inspection device to the operation device, the existing guide rail can be used without newly installing a dedicated rail on the steel tower. Investment can be reduced and images can be taken from the same viewpoint as conventional inspectors. Furthermore, there is no need to change the viewing angle of the images taken by the camera, thus improving the operability of the operating device. It is possible to above.

  In particular, when an arm that swings in the range wider than the left and right width of the tower column is installed at the upper end of the traveling vehicle, and a camera is installed on the arm, the blind spot caused by the tower column can be avoided by swinging the arm. The photographed image can be taken, and the inspection accuracy can be improved.
