The top of the placement box 505 is rotatably connected to the box cover 21, and the top of the box cover 21 is fixed with a second pull rope 22, and the top of the second pull rope 22 is located at the top of the iron tower 1.

[0034] It can be concluded that the positional relationship between the placement box 505 and the climbing passage 502 in the initial state is as follows: Figure 6 As shown, the slot 508 is locked by a U-shaped lock, and an entrance is provided on one side of the climbing channel 502. Figure 6 When the access door is in the correct position, the entrance is completely sealed by the placement box 505, which can prevent non-workers from entering the climbing channel 502 from the entrance, and prevent lawless elements and irrelevant personnel from climbing to the top of the tower to steal communication equipment. When the maintenance personnel need to perform maintenance, they open the U-lock. The key of this U-lock is only equipped by the maintenance personnel. Then they push the movable head 507 into the inside of the hollow sleeve 506, and the movable head 507 leaves the horizontal groove 509 of the vertical plate 503. At this time, the placement box 505 is no longer restricted.

Then, the box cover 21 is pressed down to close it with the placement box 505. The electromagnetic slider 602 moves outside the electromagnetic slide rail 601 and drives the rack 604 to move through the connecting rod 603. The rack 604 moves and drives the gear 605 and the pressure rod 606 to rotate counterclockwise. The pressure rod 606 rotates counterclockwise to press the accessories inside the baffle 607, which is conducive to the baffle 607. 07 The accessories on the inner side that are prone to deformation are limited. When this accessory is pressed by the pressure rod 606, it will press against the horizontal plate 609 and move the movable rod 608 and the horizontal rod 610. When the horizontal rod 610 moves, the two first connecting rods 614 move in opposite directions and carry the two sliding sleeves 613 to move in opposite directions on the outside of the horizontal rod 610. The two sliding sleeves 613 both move toward the middle of the horizontal rod 610. When the two sliding sleeves 613 move, they carry the storage box 611 and the box cover 612 in opposite directions through the second connecting rod 615. Then the storage box 611 and the box cover 612 are closed to limit the fragile accessories in the storage box 611. The inner wall of the storage box 611 is wrapped with an elastic airbag to further protect the fragile accessories.

It is mainly used for the transmission and emission of microwave, ultra-short wave, and wireless network signals. Tower 1 needs to be regularly inspected and maintained.

[0041] By setting the anti-climbing mechanism 5, the position relationship between the placement box 505 and the climbing channel 502 in the initial state is as follows Figure 6 As shown, the slot 508 is locked by a U-shaped lock, and an entrance is provided on one side of the climbing channel 502. Figure 6 When the access door is in the position, the access door is completely sealed by the placement box 505, which can prevent non-workers from entering the climbing channel 502 from the access door, and prevent lawless elements and irrelevant personnel from climbing to the top of the tower to steal communication equipment. When the maintenance personnel need to perform maintenance, they open the U-lock. The key of this U-lock is only equipped by the maintenance personnel. Then they push the movable head 507 into the inside of the hollow sleeve 506, and the movable head 507 leaves the horizontal groove 509 of the vertical plate 503. At this time, the placement box 505 is no longer restricted. Under the action of its own gravity, the placement box 505 slides along the slide rail 504 to the bottom of the climbing channel 502 to open the access door. After that, the maintenance personnel enter the climbing channel 502 through the access door, and then climb up to the observation deck 2 on the top of the tower 1 along the ladder 4. The guardrail 501 is convenient for protecting the climbing personnel.

[0042] Workers inspect or install new equipment on the tower top communication equipment on the viewing platform 2. The viewing platform 2 can provide support and rest for the workers. Since the inspection or installation takes a long time, the workers can take a lunch break on the viewing platform 2 without returning to the ground to rest, reducing the time required to go back and forth to the tower top. When the sun is shining during the lunch break, the sun protection mechanism 3 is provided to pull the first pull rope 314 and then the slider 308 moves in the circular groove 306. At this time, the spring 307 is stretched inside the circular groove 306, the disc 310 rotates and then the curved groove 311 moves outside the protrusion 313, forcing the four plug blocks 312 to retreat along the support block 309. At this time, the state of the disc 310 and the plug block 312 after movement is as shown in the figure. Figure 4 As shown, the sunshade roller curtain 301 is pulled to make the extension block 302 at the bottom pass through the through slot 304, and then the first pull rope 314 is loosened and the spring 307 is reset, causing the slider 308 to slide in the circular groove 306 in the opposite direction and causing the disc 310 to rotate in the opposite direction. At this time, the curved groove 311 moves in the opposite direction outside the protrusion 313, and then forces the four plug blocks 312 to enter the corresponding slots 305. This is conducive to fixing the extension block 302 in the extension plate 303, and then fixing the stretched sunshade roller curtain 301. The sunshade roller curtain 301 is fixed by tightening and loosening the first pull rope 314. The whole process is simple and convenient. Afterwards, the worker takes a lunch break at the bottom of the sunshade roller curtain 301.

Then, the box cover 21 is pressed down to close it with the placement box 505. The electromagnetic slider 602 moves outside the electromagnetic slide rail 601 and drives the rack 604 to move through the connecting rod 603. The movement of the rack 604 drives the gear 605 and the pressure rod 606 to rotate counterclockwise. The pressure rod 606 rotates counterclockwise to press the accessories inside the baffle 607, which is beneficial to The accessories that are prone to deformation on the inner side of the baffle 607 are limited. When the accessories are pressed by the pressure rod 606, they will press against the cross plate 609 and move the movable rod 608 and the cross bar 610. When the cross bar 610 moves, the two first connecting rods 614 move in opposite directions and carry the two sliding sleeves 613 to move in opposite directions on the outside of the cross bar 610. The two sliding sleeves 613 move toward the middle of the cross bar 610. When the two sliding sleeves 613 move, they carry the storage box 611 and the box cover 612 to move in opposite directions through the second connecting rod 615. Then the storage box 611 and the box cover 612 are closed to limit the fragile accessories in the storage box 611. The inner wall of the storage box 611 is wrapped with an elastic airbag to further protect the fragile accessories.

[0044] By means of the locking unit 6041, when the rack 604 moves, the rectangular plate 6043 is driven to move via the connecting shaft 6042, and then the inclined groove 6044 moves outside the round block 6047, forcing the limiting rod 6046 to move toward the middle of the placement box 505. During the movement, the limiting rod 6046 is inserted into the limiting groove at the bottom of the extension rod 6048, which is conducive to locking the box cover 21.

[0045] After fixing and locking, the maintenance personnel use the second pull rope 22 to pull up the placement box 505 on the top of the viewing platform 2. According to common sense, since the height of the tower 1 is very high, the maintenance personnel cannot pull the second pull rope 22 in one go, but should pull and stop. In the process of pulling and stopping, the placement box 505 will inevitably shake. Once the placement box 505 shakes, the internal accessories will collide with each other and be damaged. Therefore, the limiting mechanism 6 must be used to limit and protect fragile communication accessories and accessories that are easily deformed after collision. When the accessories need to be taken out, the electromagnetic slider 602 moves in the opposite direction to release the limit, and then the box cover 21 can be opened.

[0046] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
