The roller part 212a And a support pin 212b. At this time, the support pin 212b is fixed to the insertion passage 211a in a vertical direction, and the roller 212a is coupled to the rail 220 in a state of being freely rotatable with the support pin 212b Thereby smoothly moving the head portion 211 while preventing the head portion 211 from being rotated from the rail portion 220.

The cover portion 213 is formed at the lower end of the head portion 211 and is formed to extend downward in the radial direction of the head portion 211 and may have a structure similar to a lamp shade.

One end of the coil portion 214 is connected to the inside of the cover portion 213 and the other end is connected to the lower end of the pole 11 or the pole 11 And is fixed to the installed base structure 40. At this time, the coil part 214 has a predetermined elasticity and can be formed of a high-strength steel material so as not to be easily cut by a general tool.

At this time, in the case of installing the elevator block 210, the head portion 211 or the cover portion 213 may be installed together when the column 11 is installed for ease of installation when installed on the column 11, The structure can be divided.

In the meantime, the wake-up tower shut-off unit 210 having such a configuration is movable along the rails 220 provided on the outer surface of the pillar 11. When the wake-up tower shutoff unit 210 is moved upward, The end of the coil section 214 connected to the column 11 covers the column 11 in such a manner as to surround the outer surface of the column 11. [ When the cover portion 213 is lowered, the coil portion 214 also descends and the outer surface of the column 11 is exposed.

Accordingly, when the wake-up tower shut-off portion 210 is raised, the nose portion 214 can be prevented from wrapping around the outer surface of the column 11, It is possible to prevent the vine plant that grows along the column 11 or the coil part 214 from growing to the height of the cover part 213 by the shape of the cover part 213. [ On the other hand, when the wake-up tower interception portion 210 is lowered, the coil portion 214 is compressed with the lowering of the cover portion 213, so that the outer surface of the column 11 is exposed, The lowered cover portion 213 covers and covers the compressed coil portion 214 so that an operator can be prevented from being injured by the coil portion 214 when the robot is towed through the column 11.

The rail part 220 is provided at a position where the rotation of the head part 211 formed with the cover part 213 that moves along the column to facilitate the slide movement of the worm shaft blocking part 210 along the column 11 A pair is formed so as to be opposed to each other on the outer surface of the column 11 so as to correspond to the insertion passage 211a formed in the head portion 211. [

4, a guide groove 222 is formed at the center of the upper surface 221a so as to be in contact with the roller 212a of the guide portion 212 along the longitudinal direction. And a lower surface 221d corresponding to the upper surface 221a is fixed to the column 11. [

In addition, a plurality of wolf-top levers 223 may be formed on the rails 220 in a staggered order at predetermined intervals.

The worm-wheel-side lever 223 is formed by cutting an upper surface 221a and side surfaces 221b and 221c of the rail portion 220 and is provided below the upper surface 223a of the worm-wheel-side lever 223 so as to be rotatable in a vertical state The hinge 225 may be coupled to the coupling flange 224 formed inside the upper surface 221a of the rail portion 220 at the position of the adjacent cut surface 223c. The top surface 223a of the worm wheel lever 223 can be easily rotated so that the rotation of the worm tower lever 223 can be easily performed when the worm tower lever 223 rotates and the continuity of the guide groove 222 can be maintained ) Cut surfaces 223c and 223d are rounded. An incision groove 223e having a predetermined area is formed below the side surface 223b of the worm-house lever 223. The incision groove 223e can horizontally rotate the worm-wheel lever 223, The lower side of the side surface 223b of the worm-wheel lever 223 cut by the cutter 223e is supported by the side surfaces 221b and 221c of the rail part 220 so that the load of the worker can be supported.

The elevating part 230 may include a winding shaft 231, rotating shafts 232a and 232b, a lever shaft 233, and a wire 234, have.

The winding shaft 231 is formed to penetrate through the column 11 so that both ends of the winding shaft 231 are exposed from the predetermined height of the column 11 to the outside of the column 11. More specifically, 220 so as to be collinear with each other. A gear G, such as a bevel gear, is formed at a portion inside the column of the winding shaft 231.

The rotating shafts 232a and 232b are formed in the column along the longitudinal direction of the column 11 and are coupled to the winding shaft 231 to rotate the winding shaft 231. [ And a second rotating shaft 232b interlocked with the first rotating shaft 232a to transmit rotational force and embedded horizontally in the ground. Gears G such as bevel gears capable of transmitting rotational force are formed at both ends of each of the rotating shafts 232a and 232b.

The lever shaft 233 applies a rotational force to the second rotating shaft 232b. The lever shaft 233 is disposed perpendicularly to one end of the second rotating shaft 232b embedded in the ground, and the second rotating shaft 232b is disposed on the lower side. A gear G such as a bevel gear which can be rotated by being engaged with the gear G is formed. Further, a handle 233a or a special lever is provided on the lever shaft 233 so as to be rotatable by an attractive force. At this time, the special lever is a lever which can be operated only by a specific tool manufactured by a worker, and its structure may be various, so detailed description and explanation will be omitted.

One end of the wire 234 is connected to the winding shaft 231 and the other end of the wire 234 is connected to the wrist cap blocking portion 210. The wire 234 is connected to both ends of the winding shaft 231, Is connected to the support pin (212b) of the guide part (212) of the guide part (210). Thus, when the winding shaft 231 rotates, the wire 234 is wound or unwound at both exposed ends of the winding shaft 231, so that the elevation of the wick tower blocking portion 210 becomes possible.

The lever receiving portion 240 may be embedded in the ground or installed on the ground, with the door (not shown) having the lever shaft 233 partially received therein and provided with an additional locking device. Such a lever accommodating portion 240 prevents an unauthorized person from operating an elevator stopper portion 210 through the operation of the lever shaft 233, thereby originally shutting down operation by a non-related person, (Penetration) of moisture such as rainwater into the lever shaft 233 and prevention of intrusion of flora and fauna into the installation space of the lever shaft 233.

Hereinafter, the operation of the wick-stopping prevention apparatus 200 will be described.

5, the wrist cap cut-off portion 210 is moved to a position above the pillars 11 of the leg portion 10, and the pillars 11 Is wrapped by the coil part 214. [ In addition, the wick-down lever 223 of the rail 220 is positioned in a vertical position. Therefore, due to the position of the coil section 214 of the wrist cap cutoff section 210 and the position of the wolf cap 223, a non-related person can not operate the wolf-top lever 223 to tow the power transmission tower. Of course, although it is possible to try the wagon tower using the wolf-top lever 223 after the non-related person cuts the coil part 214, the material of the coil part 214 is formed of a material hardly cut by a general person Since the wake-up tower block 210 is moved to a relatively high position, most of the wake-up tower including the high-position coil 214 must be removed. Even if all of the diarrhea coil part 214 is removed, since the wick tower is restricted by the shape of the cover part 213, the wick tower of the non-related person can be originally sealed.

Thereafter, in order to repair the operator, it is necessary to move the wing-tower cut-off portion 210 of the column 11 closest to the maintenance point of each leg portion 10 for the wake-up tower when the wrecking tower of the transmission tower is required. The worker then places the lever of the lever accommodating portion 240 provided with the lever shaft 233 connected to the elevator stop portion 210 of the column 11 to move the elevator blocking portion 210 of the column 11 to be towed, After releasing the apparatus, the handle 233a of the lever shaft 233 is rotated.

When the worker rotates the lever shaft 233 through the handle 233a, the first rotating shaft 232a engaged with the second rotating shaft 232b and the second rotating shaft 232b is rotated. 6, the winding shaft 231 is rotated simultaneously with the rotation of the first rotating shaft 232a and the wire 234 wound on both ends of the winding shaft 231 is loosened, Is lowered along the rail part 220 by its own weight.

At the same time when the wake-up tower interception portion 210 is lowered, the coil portion 214 is also lowered while being compressed and loaded on the lower side of the column 11. When the wakeup tower interception portion 210 is completely lowered, 214 so that the coil part 214 is not exposed to the worker.

Then, the worker moves up the column 11 while operating the wolf-top lever 223 formed on the railing portion 220 to be positioned in the horizontal direction. At this time, the operation of the wolf-top lever 223 in the horizontal direction can be easily operated by putting the hand into the guide groove 222. The worker moves along the column 11 of the leg portion 10 by using the wolf-top lever 223 positioned in the horizontal direction and then performs a maintenance operation using the wander-rod 24 of the body portion 20 Move to the required point.

On the other hand, when the worker completes the maintenance work and the column 11 of the leg portion 10 descends, the wrist-tower lever 223 held by the hand is rotated to descend while being manipulated to be in a vertical state. Then, when the lowering of the worker is completed, the lever shaft 233 is operated to raise the wrist cap blocking portion 210. At this time, since the elevation of the elevation block interception part 210 along the rail part 220 is prevented during the elevation of the elevation interception part 210, the wire 234 is prevented from being twisted in the process of winding, 234 can be easily lifted up.

Thereafter, when the elevation movement of the landing block interception unit 210 is completed, the operation is completed by locking through the locking device of the lever accommodating unit 240.

As described above, the transmission tower according to the present invention also provides a wake-up tower preventing device capable of selectively activating and deactivating the wake-up prevention function on the pillars of the transmission tower legs close to the ground, The occurrence of unexpected accidents due to the wake-up towers of non-related persons can be prevented.

In addition, a wristwatch lever that can be folded on a leg portion of a leg where the conventional wristwatch is not installed can be installed, and the worker can perform maintenance work by moving to a point where the wristwatch is installed without any additional equipment.

In addition, since the power supply is not used in operation of the landing pavement prevention apparatus, it is advantageous from the viewpoint of installation and cost, and can be facilitated in terms of maintenance.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings, and all or some of the embodiments may be selectively combined so that various modifications may be made.
