Abstract

The present invention may include 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 portion of the utility pole buried upright; a tilt adjustment unit that adjusts the tilt of the utility pole by moving the pusher, which is in contact with the outer surface of the utility pole at a pressure position selected according to the direction of the tilt of the utility pole relative to the upright axis, inwardly in the radial direction, and a plurality of wedge members supported by the support frame and having wedge ends extended toward the ground, and a wedge driving unit that drives the plurality of wedge members so as to insert the wedge ends between the outer surface of the utility pole with the adjusted tilt and the ground. According to this, by restoring the tilt of the utility pole to an upright state and fixing it as a subsequent measure, the upright state can be maintained stably and efficiently.

Description

Overhead Distribution Line Pole Tilt Fixing Device with Underground Wedge Fixing Type 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. FIG. 1 illustrates a utility pole tilt fixing device using a wedge member according to one embodiment of the present invention. Figure 2 is a perspective view of the utility pole tilt fixing device of Figure 1. FIG. 3 illustrates the ready-to-strike state for the wedge member in FIG. 1. Figure 4 illustrates the impact state of the wedge member following Figure 3. FIG. 5 illustrates the strike preparation state when the strike transmission unit in FIG. 1 is used. FIG. 6 illustrates the impact state when the impact transmission unit is used in continuation of FIG. 5. FIG. 7 illustrates a utility pole tilt fixing device using a wedge member and a wedge receiving support member according to another embodiment of the present invention. FIG. 8 is a plan view showing the movement of the wedge receiving support member according to the insertion of the wedge member in FIG. 7.

Preferred embodiments of the present invention will be described in detail below with reference to the drawings. This description is intended to be detailed enough for a person skilled in the art to easily practice the invention, and it should be noted that the technical scope and concept of the present invention are not limited thereby. FIG. 1 illustrates a utility pole tilt fixing device (1) using a wedge member (22) according to one embodiment of the present invention, and FIG. 2 is a perspective view of the utility pole tilt fixing device (1) of FIG. 1. It should be noted that FIG. 1 and 2 show only the main components in a partially cut-out manner. Hereinafter, with reference to FIGS. 1 and 2, the configuration of a utility pole tilt fixing device (1) according to one embodiment of the present invention and the process of restoring and fixing the tilt (d1) of a utility pole (2) by these devices will be described. According to the present embodiment, the pole tilt fixing device (1) is a device for fixing the tilt (d1) of a pole (2) that supports an overhead power distribution line (a). The pole (2) is a structure installed upright on a roadside, etc. for power, communication, etc., and may include a telegraph pole, a communication pole, a utility pole, etc. The pole (2) is rod-shaped, with its lower end buried underground in an upright direction relative to the ground, and the power distribution line (a) is supported at its upper end. When the pole (2) is buried, the axis (c) of the pole (2) in the upright state according to the upright direction may be referred to as the upright axis (pc). The pole (2) is manufactured by mixing reinforcing steel and concrete, and gravel may also be mixed, but is not limited thereto. The utility pole tilt fixing device (1) includes a support frame (3).
