Embodiment Construction

[0014] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0015] Such as figure 1 and figure 2 Shown, according to a kind of hyperstatic radar / antenna bracket dynamic leveling method of the present invention, hyperstatic radar / antenna bracket comprises vertically arranged central column 10, and four horizontal supporting legs 20 that are arranged on central column 10 lower ends , one end of the horizontal support leg 20 away from the center column 10 is provided with a support foot 21 adjustable in height along the vertical direction, and the upper end of the center column 10 is provided with a turntable for installing radar / antenna; the leveling method comprises the following steps: Step S1: Set the first spirit level 31 and the second spirit level 32 on the turntable to indicate that the directions are perpendicular to each other; step S2: adjust the radar / antenna pointing set on the turntable to be horizonta...

Abstract

The invention provides a statical indetermination radar / antenna support dynamic leveling method which comprises the followings steps of a step S1 of setting a first gradienter and a second gradienter with indication directions which are mutually vertical on a rotary table; a step S2 of adjusting the indication directions of a radar / antenna on the rotary table to be horizontal; a step S3 of controlling the rotary table to rotate around an azimuth axis to enable the radar / antenna to direct to a plurality of positions, and respectively adjusting supporting legs on end portions of four horizontal landing legs to enable indication of the first gradienter to be horizontal when the radar / antenna directs to the plurality of positions; and a step S4 of continuously controlling the rotary table to rotate around the azimuth axis to enable the radar / antenna to direct to a plurality of positions, maintaining the indication of the first gradienter to be horizontal, and adjusting supporting legs on end portions of four horizontal landing legs to enable indication reading at each position of the second gradienter to be unanimous. The statical indetermination radar / antenna support dynamic leveling method enables the rotary table to be adjusted to be in a horizontal state under biggest gravitational torque, and then enables stiffness of each horizontal supporting leg to be adjusted to enable stress of each supporting leg to be unanimous.

Description

technical field [0001] The invention relates to the field of radar / antenna brackets, in particular to a dynamic leveling method for hyperstatic radar / antenna brackets. Background technique [0002] The radar / antenna bracket is the base of the radar antenna and its driving device (turntable), and the turntable is in a horizontal state by adjusting the bracket. The adjustment of the portable bracket faces two problems, one is the problem of static indetermination, and the other is the problem of micro-deformation of the structure. [0003] In order to improve the windproof problem of the portable bracket, the radar / antenna bracket adopts an ultra-static structure. For example, the 4-support leg scheme (super-static structure) is 1.73 times the wind resistance of the 3-support leg scheme (static structure). However, the statically indeterminate structure brings difficulties to the horizontal adjustment of the support. Due to its statically indeterminate characteristics, the r...
