Description

A directional antenna angle adjustment device

technical field

The invention relates to the field of communication technology, in particular to a device for adjusting the angle of a directional antenna.

Background technique

The pitch angle of the existing plate antenna is mostly adjusted manually. When the pitch angle needs to be adjusted, it is necessary to loosen the connection between the upper connection component and the pole with a wrench, and then push the upper part of the plate antenna away from the pole by hand. direction to move. When the adjustment is finished, the upper connection assembly needs to be tightened with a wrench. Because the poles are mostly installed on the platform at the top of the tower, the distance from the ground is usually about 45 meters. Working at such heights is dangerous. At the same time, technicians need to carry wrenches when climbing the tower. It has brought a lot of inconvenience.

Contents of the invention

Aiming at the problems existing in the above-mentioned prior art, the present invention provides a directional antenna angle adjustment device, which can conveniently adjust the pitch angle of the plate antenna, does not require technicians to climb the tower for operation, and can improve the safety factor of technicians' work .

The invention provides a directional antenna angle adjustment device, which includes a vertically arranged pole and a platform, the pole is fixedly connected to the antenna body through an upper connection assembly and a lower connection assembly, and the middle part of the platform is fixedly provided with a fan-shaped The ratchet piece, the lower end of the holding rod is hinged to the lower part of the fan-shaped ratchet piece, and the holding rod is fixedly provided with a connecting seat and a cylinder with covers at both ends on the lower right side of the lower connection assembly. A pulley is provided; a spring matching its inner diameter and a cylindrical slider are sequentially arranged in the cylinder from top to bottom, the lower end of the slider is fixedly provided with a ratchet, and the ratchet passes through the lower end of the cylinder The cover plate matches the tooth groove of the fan-shaped ratchet piece, the upper end of the slider is connected with one end of the rope, and the other end of the rope passes through the cover plate at the upper end of the cylinder and goes around the pulley.

The platform is vertically provided with a limit stop on the left side of the pole, and the limit stop is set near the hinge point at the lower end of the pole to limit the maximum angle of rotation of the pole to the left.

The left side of the lower part of the pole is provided with a spring seat 1, and the left part of the platform is provided with a spring seat 2, and the spring seat 1 and the spring seat 2 are connected by an extension spring.

In the present invention, the lower end of the pole is hinged to the fan-shaped ratchet on the platform, and ratchet teeth that can be pulled by a rope are set on the pole to control the rotation angle of the pole relative to the platform, so that the pitch angle of the antenna body can be driven to change. In this way, the adjustment of the pitch angle of the antenna can be realized, and the rope can be extended to the bottom of the iron tower. In this way, it is not necessary for technicians to climb the tower to carry out dangerous work at high altitudes, which can effectively improve the safety factor of technicians.
