Problems solved by technology

The disadvantages of the above-mentioned exposed ball screw mechanism are: on the one hand, considering the limitation of the installation space on the top of the antenna seat, the thrust rod should have a long jacking stroke, and the minimum length after the full return stroke should be as short as possible. Possibly short, and the above ball screw structure obviously cannot meet the above requirements
On the other hand, since the air traffic control radar is erected on the top of mountains, islands or radar towers all the year round, it must have the all-weather working ability under severe weather conditions such as thunderstorms; however, since the existing air traffic control radar antenna pitching mechanisms are all exposed mechanisms, Under the long-term erosion of outdoor rainwater, it is not uncommon for the ball screw structure to corrode, get stuck, and fail, which seriously affects the normal pitching work of the air traffic control radar antenna

Embodiment Construction

[0029] For ease of understanding, the attached Figure 1-6 The specific implementation structure and work flow of the present invention are described as follows:

[0030] In the following, as a middle rotary screw sleeve 20 with a stepped hole wall, after it has a small hole end and a large hole end, the small aperture section is a section of the hole wall between the hole shoulder and the small hole end; the corresponding , the large-aperture section is a section of the hole wall between the hole shoulder and the end of the large hole. Similarly, the middle rotary screw sleeve 20 has a stepped shaft-shaped outer wall, the end with a relatively larger diameter is its large end and the end with a relatively smaller diameter is its small end; a section of the outer wall from the shaft shoulder to the small end is its small diameter. section, and a section of outer wall from the shoulder to the big end is its large diameter section.

Abstract

The invention belongs to the technical field of air traffic control radars, and particularly relates to an octave rain-proof adjusting component and an air traffic control radar antenna elevation mechanism employing the same. The adjusting component comprises a bottom support shaft, a middle rotary thread sleeve and a top rainproof sleeve, which are coaxially sleeved one by one, wherein the top rainproof sleeve is in a sleeve structure of which an opening is downward; and the middle rotary thread sleeve can carry out rotary motion along the axis, so that the bottom support shaft and the top rainproof sleeve carry out axially opposite or separate synchronous screw-thread fit motion. Compared with a traditional structure, the component has smaller minimum length and longer jacking stroke when having extremely high rain-proof capability; and the working performance can be significantly improved. Meanwhile, the invention provides the air traffic control radar antenna elevation mechanism employing the adjusting component. The air traffic control radar antenna elevation mechanism structurally comprises a three-point support system comprising two groups of octave rain-proof adjusting components and a group of hinge seats, so that the maintenance frequency of the existing air traffic control radar antenna elevation mechanism is significantly lowered.

Description

technical field [0001] The invention belongs to the technical field of air traffic control radar, and specifically relates to a multi-program rain-proof adjustment assembly with a nested structure and an applied air traffic control radar antenna pitch mechanism, which are used to adjust the air traffic control radar antenna relative to the antenna base and the installation reference. pitch angle between. Background technique [0002] Air traffic control radar is mainly used in the field of air traffic control. It is an air intelligence radar for scheduling aircraft flights and ensuring flight safety. The structure of the traditional air traffic control radar, its structure is described in the Chinese Patent Publication No. "102195133A" and the patent title is "Radar Antenna Pitching Mechanism Based on Ball Screw Double Push Rod Structure", most of which rely on exposed balls The screw mechanism acts as a thrust rod, so that the air traffic control radar antenna can swing al...
