detailed description

Embodiment of the present invention: as shown in Figure 1, adopt conventional shaped steel to make a hollow lifting tower 1 (its structure as shown in Figure 2), on lifting tower 1, existing commercially available electric winch 2 and The conventional transmission mechanism connected with the electric winch 2 installs the lifting pallet 3 in the lifting tower 1 (its structure is shown in Figure 4), and connects the lifting pallet 3 with the transmission mechanism, and the lifting action of the lifting pallet 3 Controlled by the electric winch 2, a lifting tower 4 with a multi-section structure is placed on the lifting pallet 3 (that is, the lifting tower 4 is made into a structure connected by several sections, as shown in Figure 3, which is a section of the lifting tower structure). A conventional antenna base 5 is installed on the lifting tower 4 top, and one side of the lifting tower base 1 is provided with a window 6 that can pass through a section of the lifting tower 4 .

In order to further save production costs, the present invention provides a transmission mechanism structure, that is, the transmission mechanism is composed of an upper roller 7 placed above the electric winch 2 and two lower rollers 8 placed below the electric winch 2, and then the electric winch 2. The upper roller 7 and the lower roller 8 are connected by a wire rope 9 .

In order to ensure erection in an environment that is difficult to connect to electricity and further improve the practicability of the present invention, a conventional hand winch 10 connected with a transmission mechanism can be installed on the lifting tower 1 .

In order to ensure stability when the lifting tower 4 rises or is still, and further improve the reliability of the present invention, the positioning channel steel 11 can be fixedly connected in the lifting tower base 1, and the positioning channel steel 11 is contacted with the outer side of the lifting tower 4 to start to the role of clamping and positioning.
