During installation, the plug-in box 7 is hammered into the ground according to the construction clearance, and then between the adjacent limiting plates 9 Hammer in the connecting strip 10, and finally hammer the gusset 15 into the corner of the limiting mechanism 2 to make it a whole, thereby limiting the soil at the bottom of the tower crane body 1 and increasing the stability of the installation of the tower crane body 1;

Then the enclosure mechanism 3 is installed. During installation, the cover plate 19 is fixed on the top of the first extension plate 18 through bolts, and the protective frame 20 is fixed between the cover plates 19 through bolts. Then the anti-climbing mechanism 4 is installed. During installation, Place the positioning rod 22 on the anti-climbing mechanism 4 in the adjacent placement groove 27, then cover the pressure plate 28 and fix it with the bolt 29. Use the clamp block 30 to fix the positioning rod 22, and pass the first anti-climbing mechanism 4 to the positioning rod 22. The climbing frame 23 and the second anti-climbing frame 25 cooperate to prevent unrelated persons from climbing;

After the dehumidification mechanism 5 is connected to the pipeline, the fan 32 is started. The fan 32 extracts air and discharges the air into the plug-in box 7 through the main air pipe 33. After passing through the plug-in box 7, the fresh air enters under the restriction of the partition 12. to the bottom of the plug-in box 7, and then passes through the communication hole 13, and is discharged through another plug-in box 7 again. The moisture at the bottom of the tower crane body 1 enters the plug-in box 7 through the dehumidification hole 14, and is finally discharged with the air flow, maintaining The moisture of the soil at the bottom of the tower crane body 1 improves the load-bearing capacity of the soil;

After the gas enters the filter box 36, it is filtered by the filter 40 inside it, which reduces the dust entering the box 7 and reduces the number of cleaning times of the box 7. Part of the exhausted gas enters the ventilation box 46 through the driving air pipe 37. , when the gas passes through the ventilation box 46, it drives the driving shaft 47 to rotate by blowing the blades 49. The driving shaft 47 drives the circular gear 48 to rotate, and then drives the ring gear 44 to rotate. The ring gear 44 drives the mounting shaft 42 and the brush plate 72 to rotate. Dust and impurities on the surface of the filter 40 are cleaned to prevent clogging of the filter 40 and improve the ventilation effect;

When the gear ring 44 rotates, it drives the lever 54 to rotate. After the lever 54 comes into contact with the drive rod 52, the scraper 51 is pushed by the drive rod 52 to move on the bottom inner wall of the filter box 36. After the lever 54 is out of contact with the drive rod 52, , the scraper 51 is reset under the pull of the tension spring 53, and then pushes the dust and impurities at the bottom of the filter 40 to both sides;

When wind ventilation is used, the rotating sleeve 55 makes the driving fan blade 58 face the wind under the action of the guide blade 60, and uses the wind power to drive the driving fan blade 58 to rotate, thereby driving the first pneumatic shaft 57 to rotate, and the first pneumatic shaft 57 passes through the bevel gear 59 drives the second pneumatic shaft 61 to rotate, and the second pneumatic shaft 61 drives the blower blade 63 to rotate, so that natural air enters the main air pipe 33 through the auxiliary air pipe 34, thereby achieving the ventilation effect;

When the tower crane body 1 tilts, the tower crane body 1 pulls the storage box 64 to move, thereby driving the partition 65 to move. The partition 65 is damaged under the pulling action of the connecting shaft 70, causing the nitric oxide and nitric oxide on both sides of the partition 65 to move. The oxygen mixes and generates reddish-brown gas, which alerts staff.

However, as is well known to those skilled in the art, the working principle and wiring method of the fan 32 are commonplace and belong to conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can proceed according to their needs or convenience. Any option.
