Description

Guide ring rope for transmission lines for transmission lines

The present invention relates to a guide ring rope for transmission lines, and more particularly, to a guide ring rope for transmission lines, in which a wire is sandwiched between a steel tower and a steel tower in order to prevent a wire from falling on the ground when a wire is replaced or newly installed. .

 Transmission towers are installed along the lines of transmission and distribution lines mainly in the outskirts of the city, but they are installed by passing through the road, passing through the village, upper part of the building, or passing over the transmission and distribution lines of other towers Protected object ').

 Conventionally, a 'footrest scaffold' was used when replacing or installing a new transmission line. The footrest scaffold is a temporary structure required to protect the object from deflection or disconnection of the power line when there is a lower protection object under the line in the working line.

 For the method of installing the footrest scaffolding, a steel reclaiming method, a pylon footing method, and a public net method are applied.

 The steel foot support method is a structure that uses a circular steel to assemble a scaffold to protect the object and fix it using a branch wire. A scaffold is a method of assembling a scaffold to a height to be protected at both ends of a lower protective object, and enclosing both ends of the scaffold with a rope.

 The pylon foot footing method is a method of protecting the object to be protected by installing temporary steel towers on both sides of the object to be protected and connecting the upper part of the pylon through the rope.

 The public net construction method is a protection net device that installs a protective net between power transmission towers. It is a method to protect the object by a plurality of ropes which are installed on the processing branch line adjacent to the transmission line and connected to the pulley at the other end.

 The above-mentioned two foot support methods (steel foot support method, pylon foot support method) are ground installation type, and when there are constraint factors on the installation place (steep slopes, agricultural lands, canyons and rivers) There is a problem that a non-installation position occurs.

 Also, while the power line can protect the object to be protected from the deflection of the wire, there is a risk of a safety accident due to the inability to prevent the deviation from the outside of the protection range of the footrest.

 The construction of the pylons should be done in the same manner as the permanent pylons (basement and phase members), so the tasks (installation of license, pylon, installation site and access roads) Lt; / RTI > In addition, there are problems such as deforestation and deforestation for securing installation site and access road site.

 Unlike the ground-mounted structure, the aerial net for public installation is advantageous in that it is installed using the ground wire. However, safety problems may occur due to the installation of the wake-up tower along one disconnection line of the ground wire. Depending on the height of the object to be protected, And a pile is put on the lower part.

 Accordingly, there is a case where the footrest itself is not installed, the footrest is installed at one side, and a temporary operation is carried out under a temporary measure using heavy equipment, which poses a serious safety problem.

Korean Patent Laid-Open Publication No. 10-1181453, filed on September 11, 2012, entitled " Protective net device and method for installing and dismounting a protective net using the same, " is a prior art document related to the present invention.

 In order to solve the problems of the prior art, the present invention provides a guide ring rope device for protecting a cable under a transmission line from a deflection or dropping of a wire under a transmission line in a crossover section during a new installation of a transmission line, .

 The guide ring rope apparatus according to the present invention comprises: a wire seating rope which is seated on the transmission line and advanced forward; An intermediate connecting rope to prevent the breakage of the transmission line; A lower roller support for supporting the wire when the wire is deflected or dropped; An upper connection for increased convenience during transportation and installation; A guide rope for connecting a steel tower to fix the transmission tower between the tower and the tower; Upper / lower connecting ropes that maintain the spacing between the lower and upper guide ring ropes; And a diagonal fixed rope for fixing the guide ring rope.

 The wire seating rope is composed of three bending portions so as to be applicable to both the short-circuit conductor and the corridor of the power transmission wire. When the wire rope is seated in the center wire only, it is a single conductor. It is used for power transmission line of corridor. The outside of the bending part is fixed with PE pipe to keep the level, and the inner rope is connected to the upper end using the insulated wire and the end is connected to the upper end using the thimble.

 The wire seating rope may include aluminum material, and all the wires of the transmission wire may be applied.

 The intermediate connecting rope has a function of preventing the wire from escaping outward when the transmission wire is replaced or newly installed, and can be connected and used continuously according to the scale of the transmission tower.

 The middle connecting rope is composed of a transparent rubber lacquer which protects the rope when it contacts with the insulating rope. The upper end of the insulating rope can be connected to the upper connecting rod, and the lower connecting rod can be connected to the lower roller supporting rod.

 The lower roller pedestal has a function of preventing an electric wire from falling to the floor; Roller function to allow rolling when contacting wires; Intermediate rollers with horizontal widths from top arm to bottom arm of transmission tower; Guide ring may include a connection to keep the rope horizontally spaced.

 The lower roller support includes a horizontal connection device which enhances the rolling function of the roller by using a thrust bearing and the intermediate bearing which prevents warpage by using a half ball bearing and maintains a gap during operation of wind or external force can do.

 The upper connector allows all devices to be connected at the top; The ring bolt may include a wire seating rope, and the remaining three holes may include a device connecting the upper connecting rope to the intermediate connecting rope.

 The guide rope for connecting the steel tower includes: a rope for fixing the transmission towers; And may include a rope for connecting the upper horizontal rope and a long rope for connection of the steel tower, except for a portion for protecting the lower baffle.

 The upper / lower connecting ropes have a function of maintaining the distance between the upper and lower ropes because the upper and lower wire ropes and the lower roller bracket are installed in units of 5 or 10, respectively. A function to connect flat rope to guide rope for connection of steel tower; And may include a function of preventing shaking in the action of external force.

 The above diagonal connection rope has a function of fixing the guide rope and the lower rope for connecting the steel tower; It is an insulation rope with the function of preventing the transmission wires from leaving the outside with the same function as the intermediate connection rope.

 According to the present invention, a guide ring rope can be installed on a wire without using the land of a protection point under a steel tower. Therefore, it took a considerable amount of time and money to obtain the consent of the landlord by installing the footrest on the protection point when replacing or installing the new transmission line. However, since the invention does not require the landlord's consent, it can be installed quickly .

 In addition, the present invention can work simultaneously at the time of demolishing the spacer damper, which is a work to be carried out in demolishing a wire, so that installation time can be shortened.

 In addition, the present invention can suitably adjust the intermediate connecting ropes to suit the size and type of transmission tower. Therefore, guide ring rope can be used jointly.
