Fig. 7 is a schematic view from above of the working position, with only the tower legs 21 and the working platform 3 shown for clarity of illustration, and with other structures hidden. As shown in fig. 7, the number of work platforms 3 is four and corresponds one-to-one to the tower legs 21. The antenna assembly of the communication base station is generally installed on the tower leg 21 and faces the outer side of the electric power iron tower 2, so that the arc-shaped groove 33 is formed in the operation platform 3, and the operation platform 3 is prevented from blocking the installation position of the antenna assembly to cause that the antenna assembly cannot be installed.
The invention also provides a using method of the electric power iron tower extension device, the method uses the electric power iron tower extension device to install an additional structure on the existing electric power iron tower 2, and comprises the steps from S1 to S7, and the steps are respectively and specifically described below. Such additional structures include, but are not limited to, communication base stations.
And S1, the long support rod 1 is in a flat state, one end of the long support rod is close to the electric iron tower 2, and the other end of the long support rod is far away from the electric iron tower 2.
After the support long rod 1 is erected, one end close to the electric power iron tower 2 becomes the lower end of the support long rod 1, and the other end far away from the electric power iron tower 2 becomes the upper end of the support long rod 1. Specifically, the long supporting rod 1 is formed by splicing sub-rods 11, and the support legs 12 are arranged on the sub-rods 11 at proper positions to lift the long supporting rod 1 off the ground. After the long support rod 1 is assembled, the operation platform 3 is installed at one end of the long support rod, which is far away from the electric iron tower 2, and the included angle between the operation platform 3 and the long support rod 1 is roughly adjusted through the adjusting mechanism 7.
And S2, rotatably arranging one end of the long supporting rod 1 close to the electric iron tower 2 on the ground.
This step may be performed before step S1. That is, before the step S1 is performed, the base structure 5 is provided on the concrete foundation of the electric power tower 2, and the height of the base structure 5 is adjusted by the ground-supporting rod 53. Base structure 5 sets up and accomplishes back and electric power iron tower 2 fixed connection, can connect first sub-pole 11 this moment on supporting part 54, then connects gradually next sub-pole 11, reaches preset length until supporting long-pole 1, splices last sub-pole 11 to install work platform 3 on this sub-pole 11. The work platform 3 is also a detachable structure, which is convenient for transportation.
And S3, a fixed pulley is arranged on the electric power iron tower 2.

The fixed pulley can be fixedly connected with the electric power iron tower 2 through the locking assembly 55, so that the position and the posture of the fixed pulley are kept fixed in the using process.
And S4, a pull rope is arranged, one end of the pull rope is connected with one end, far away from the electric iron tower 2, of the support long rod 1, and the other end of the pull rope hangs down to the ground after passing around the fixed pulley.
And S5, pulling the pull rope to rotate and erect the long support rod 1, so that the working platform 3 reaches the working position.
The support long rod 1 can be pulled up by pulling the pull rope to droop to one end of the ground on the ground. It should be noted that the included angle between the long support rod 1 and the ground is gradually increased after being pulled up until the included angle is increased to 90 degrees; because tower leg 21 is the slope, need to support stock 1 and continue to rotate a small segment angle this moment, if support stock 1 free rotation at this moment, support stock 1 can hit electric power iron tower 2 under the effect of dead weight. Therefore, the upper end of the long support rod 1 can be connected with a reverse pull rope besides the pull rope, and after the long support rod 1 rotates 90 degrees, the reverse pull rope is pulled on the ground to prevent the long support rod 1 from colliding to the electric power iron tower 2, so that the long support rod is slowly close to the electric power iron tower 2.
And S6, connecting the locking mechanism 4 with the electric power iron tower 2 to keep the operation platform 3 fixed.
The locking mechanism 4 comprises a third connecting rod, which is similar in structure to the first connecting rod 52 and the second connecting rod 58; one end of the third connecting rod is rotatably connected with the upper end of the long supporting rod 1, and the other end of the third connecting rod is locked with the electric iron tower 2 through a locking assembly 55; close locking Assembly 55's opening and shutting arm 62, surround tower leg 21, then screw up locking bolt 64, through drive screw make right angle briquetting 631 compress tightly the inner wall of angle bar 22 can, easy operation, convenient high efficiency.
And S7, the operator climbs the electric power iron tower 2 to reach the operation position and gets on the operation platform 3 to start operation.
In the operation process, ground personnel convey the materials to be installed for aerial operators through the feeding pulleys 31 until the installation operation is completed.
After the operation is accomplished, will support stock 1 and set level to ground through playing the stay cord, dismantle support stock 1, operation platform 3, base structure 5, construction repeatedly usable next time.
Compared with the prior art, the application method of the electric power iron tower extension device provided by the invention has the advantages that the operation platform 3 can be conveniently arranged in the air by applying the electric power iron tower extension device, the safety of aerial operation personnel is protected, a standing space is provided for the aerial operation personnel, the operation efficiency is improved, an additional structure is conveniently and efficiently installed on the electric power iron tower 2, and the extension of the electric power iron tower 2 is realized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
