Description

[Detailed explanation of the idea] The present invention relates to an antenna device for microwaves.

In particular, it relates to an antenna device that can be assembled, installed, disassembled and removed.

Microwave antenna equipment is sometimes constructed in remote areas where it is difficult to transport materials, and may require relocation in other cases for military use.

The object of the present invention is to provide an antenna device that can be constructed and dismantled by an extremely small number of people using small and small materials, without requiring special workers such as crane trucks.

This invention consists of a steel tower with a rail on the front, a rail on the ground that connects to this rail, a pedestal that moves along these rails, a pulley that lifts this pedestal, and a winch that winds the wire of this pulley. It is characterized by a structure in which a frame is placed on a rail on the ground surface, an antenna is assembled on this, and this is hoisted onto a steel tower using a winch and a pulley.

This will be explained with reference to the drawings.

FIG. 1 is a side view, FIG. 2 is a plan view, and FIG. 3 is a front view.

A steel tower 1 is erected almost vertically on the ground surface, and two parallel vertical rails 2 are attached to its front surface.

Furthermore, horizontal rails 3 are installed on the ground surface in communication with this vertical rail 2 and having the same spacing.

In order to be able to move along these two sets of rails 2 and 3,
A pedestal 6 supported by four rotating wheels 5 is arranged.

One end of this frame 6 is connected to a pulley 7 attached to the top of the steel tower 1.
The wire 8 is suspended by a wire 8, and the tip of the wire 8 is guided so as to be wound around a manual winch 9 placed near the ground surface of the steel tower 1.

Initially, the pedestal 6 is placed on the horizontal rail 3 on the ground surface,
Here, the antenna 10 is assembled and attached to the pedestal 6.

When this attachment is completed, the wire 8 is wound up by the winch 9, and the pedestal 6 is moved from the horizontal rail 3 to the horizontal rail 2.

Furthermore, the winch 9 is hoisted up, and the pedestal 6 and the antenna 1 are
0 to the specified position.

In the figure, reference numeral 11 denotes a guide for preventing the pedestal 6 from derailing from the rail 2 during lifting.

The pedestal 6 and the rail 2 or the steel tower 1 are fixed at a predetermined position using bolts or other appropriate methods, and the winch 9 and the wire 8 are removed.

The horizontal rail 3 can also be removed.

When the need arises, the antenna can be easily pulled down and disassembled by reversing the above procedure.

The steel tower 1, rails 2, 3, pedestal 6, etc. of the above structure can all be transported as short steel bars and assembled on site.

In this example, the antenna 10 is a large one with a reflector, and includes a center drum 12 with four panels, a horn support 13. I will warn you from panel 15.

All of these can be disassembled into small parts and transported, and can be assembled by a small number of people on the pedestal 6 using only ordinary small tools.

As mentioned above, the device of the present invention is designed to avoid parts that can be disassembled and transported by ordinary small vehicles or manual transport means, and is designed to be specially designed by a very small number of workers at the construction site. It can be assembled without the need for special tools or equipment such as cranes.

In addition, it is easy to remove or relocate if necessary.
It has excellent effects.
