Abstract

The present invention relates to a tilt fixing device for a utility pole supporting an overhead power distribution line, comprising: a support frame fixedly installed on the ground along the outer circumference of the lower ground portion of a vertically buried utility pole; a detachable pressure unit having a detachable carrier that can be installed on the support frame to switch between a mounted state and a detached state, and a movable pusher unit installed on the detachable carrier to be driven to move radially with respect to the vertical axis of the utility pole. The device comprises a pusher body connected to the movable pusher part and configured to move radially together with the movable pusher part, having a pressure surface at the inner end of the radial direction that contacts the outer circumference of the utility pole, and at least one fixed pusher part having a fixing part capable of fixing the pusher body to the support frame at one position in the radial direction. In the mounted state of the detachable pressure unit, the fixed pusher part, whose pressure surface contacts the outer circumference of the utility pole, is moved inward in the radial direction by the driving of the movable pusher part at a pressure position selected according to the direction of the tilt of the utility pole with respect to the upright axis, thereby adjusting the tilt of the utility pole; and in the detached state of the detachable pressure unit, the tilt of the utility pole can be fixed by the fixed pusher part fixed to the support frame through the fixing part. Accordingly, when restoring and fixing the tilt of the utility pole to an upright state, the tilt of the utility pole can be fixed more firmly, thus allowing the upright state to be maintained more stably and efficiently.

Description

Overhead Distribution Line Pole Tilt Fixing Device Using Detachable and Fixable Pusher Unit The present invention relates to a device for a utility pole supporting an overhead power distribution line, and more specifically, to a device for restoring and fixing the inclination of a utility pole. Utility poles are buried at their lower ends underground to support overhead power lines and stand upright stably. However, due to factors such as ground subsidence, utility poles may inevitably tilt; once they begin to tilt, the weight of the pole and the power lines accelerates the tilt, potentially causing them to overturn in an instant. Accordingly, there may be a technology to restore the tilt by applying pressure to the pole in the opposite direction of the tilt. However, even with this technology, if no follow-up measures are taken after temporarily erecting the utility pole, a problem arises in which the pole is highly likely to tilt again later.
