Problems solved by technology
The short-wave whip antenna can be regarded as a cantilever beam. Because the antenna is very high and heavy, and the installation environment is vibrating and swaying, the inertia force generated by the antenna is very large. It is easy to loosen after being locked by a general folding device, and it is not easy to lock tight, easy to cause damage to the equipment
However, the use of an electric folding device requires a large installation space, high cost, and inconvenient regular maintenance

The invention provides a whip antenna folding device which comprises an insulator clamp, an antenna mast clamp and a worm gear deceleration screw rod. The insulator clamp and the antenna mast clamp are connected through the worm gear deceleration screw rod. The insulator clamp is used for fixing the whip antenna folding device to the insulator base of a whip antenna and provides a fulcrum for folding / unfolding operation of the whip antenna. The antenna mast clamp is used for tightly holding the antenna mast of the whip antenna. The worm gear deceleration screw rod, the insulator clamp and theantenna mast clamp together form a crank rocker transmission mechanism. The stretch and the retraction of the worm gear deceleration screw rod fold and unfold the antenna mast respectively. The whip antenna folding device can fold the whip antenna, is simple and efficient in operation, safe and reliable, and suitable for one man operation, just requires a small installation space, is simple in manufacturing process, and is easy to repair and maintain.
Description
technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a whip antenna folding device. Background technique [0002] The short-wave whip antenna is a widely used antenna, which is widely used on land and ships. Due to the length and weight of many short-wave whip antennas, it often requires a large number of manpower and large-scale hoisting equipment to complete the installation of the antenna and the repair and maintenance of the antenna. However, for short-wave whip antennas erected in mountainous areas and ships, due to the limitation of environmental conditions, manpower and equipment cannot meet the demand, so short-wave whip antennas in these environments often have difficulties in installation, maintenance and repair. The short-wave whip antenna is installed on the surface ships and is an important communication equipment. It has high requirements for maintenance and maintenance, and the antenna mast needs to ...
