This allows workers to disassemble the first antenna mast 10, the second antenna mast 13, the third antenna mast 14, and the communication antenna 15 without the need for climbing tools, making the overall operation convenient and quick, greatly facilitating the work of personnel.

[0027] Example 2:

[0028] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 and Figure 4As shown, a fixed frame 25 is fixedly connected to the middle of the bottom of the outer surface of the counterweight box 5. Both ends of the inner cavity of the fixed frame 25 are movably connected to a stabilizing crossbeam 8. The bottom of the stabilizing crossbeam 8 is threadedly connected to a threaded support 7.

At the same time, the pin hole 26, the pin seat 24, and the pin rod 23 effectively lock and limit the stabilizing crossbeam 8 as it extends to both sides of the fixed frame 25, preventing the stabilizing crossbeam 8 from shifting during use.

[0030] Example 3:

[0031] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a guide frame 28 is fixedly connected to the upper left side of the outer surface of the equipment protective box 1. A locking bolt 27 is threadedly connected to the upper end of the front surface of the guide frame 28. An adjusting rod 18 is movably connected to the inner cavity of the guide frame 28. A guide wheel 19 is movably connected between the upper left side of the adjusting rod 18 and the surface of the adjusting wire rope 17 via a bearing. A brake caster 9 is movably connected to the bottom of the outer surface of the counterweight box 5 via a bearing. There are four brake casters 9. Antenna mast mounting brackets 12 are fixedly connected to both ends of the right side of the outer surface of the equipment protective box 1. The AC power distribution equipment 2, the switching power supply 3, and the main body of the communication equipment 4 are fixedly installed in the inner cavity of the equipment protective box 1 from top to bottom. Heat dissipation holes are opened on both sides of the equipment protective box 1. A protective box door is movably connected to the right end of the back of the equipment protective box 1 via a hinge.

[0032] In this technical solution, by setting up the guide frame 28, locking bolt 27, adjusting rod 18 and guide wheel 19, when personnel adjust the angle of the communication antenna 15, they can move the adjusting rod 18 and guide wheel 19 upward along the inner cavity of the guide frame 28, so that the guide wheel 19 can protrude above the equipment protective box 1. Under the action of the locking bolt 27, the adjusting rod 18 and the guide frame 28 can be effectively locked and limited, so that the guide wheel 19 can effectively guide the adjustment wire rope 17 during the unwinding process, avoiding contact between the adjustment wire rope 17 and the equipment protective box 1 and causing wear. The brake caster 9 makes it easy for personnel to move the whole unit. The antenna rod placement frame 12 makes it convenient to store and place the second antenna rod 13 and the third antenna rod 14 that have been disassembled by personnel.

[0033] The working principle of this utility model is as follows: Through the support base 21 and locking bolt 22, the bottom of the first antenna mast 10 can be effectively supported and fixed during overall use. Simultaneously, the first antenna mast 10, the second antenna mast 13, and the third antenna mast 14 can effectively support the communication antenna 15, facilitating its use. When the communication antenna 15 needs to be disassembled when not in use, the locking bolt 22 can be removed from the support base 21 and the bottom of the first antenna mast 10 using tools. Then, by rotating the worm gear 31, the worm wheel 11 and the winding shaft 30 can be driven to rotate. Simultaneously, the rotation of the winding shaft 30 continuously adjusts the steel wire rope 1... 7. Unwinding is performed, and with personnel pushing the first antenna mast 10 to rotate along the pivot 20 on the support base 21, the first antenna mast 10, the second antenna mast 13, the third antenna mast 14, and the communication antenna 15 can continuously rotate and adjust their angles to the right. As the adjusting wire rope 17 is continuously unwound, the height of the first antenna mast 10, the second antenna mast 13, the third antenna mast 14, and the communication antenna 15 gradually decreases. This allows personnel to disassemble the first antenna mast 10, the second antenna mast 13, the third antenna mast 14, and the communication antenna 15 without the need for climbing tools. The overall operation is convenient and quick, greatly facilitating the work of the personnel.
