Rapid automatic leveling control method for multi-point supporting heavy-load platform

Abstract

The invention discloses a rapid automatic leveling control method for a multi-point supporting heavy-load platform; the heavy-load platform comprises four main supporting legs, a plurality of auxiliary supporting legs and a double-shaft horizontal angle sensor, wherein the method comprises the following steps: S1, all the supporting legs stretch out, and each supporting leg stops moving after each supporting leg touches the ground; S2, the four main supporting legs stretch out independently and stop moving after lasting for a set time; S3, according to the included angles between the X and Y axes of the heavy-load platform and the horizontal plane fed back by a double-axis horizontal angle sensor, the lifting motion of the main supporting legs 1 and 3 or the main supporting legs 2 and 4 is adjusted until the included angles between the X and Y axes of the heavy-load platform and the horizontal plane approach to a set dead zone; S4, all the auxiliary supporting legs stretch out and stop until the auxiliary supporting legs touch the ground; and S5, all the auxiliary supporting legs extend to the set distance at the same time, so that ground contact compaction is achieved. The problem that the auxiliary supporting legs interfere with the levelness is solved, the success rate of multi-point automatic leveling is greatly increased, and the wind resistance and stability of the heavy-load platform are greatly improved.

Description

technical field [0001] The invention relates to a fast automatic leveling control method for a multi-point support heavy-duty platform for special equipment, so that after the special equipment is transported to the work site, the level adjustment of the heavy-duty platform can be completed in the shortest time, which is a special equipment. Erection wins precious time. Background technique [0002] Now ground special equipment is developing towards the direction of high maneuverability and quick response. In order to meet this requirement, the traditional electronic cabin is canceled, which causes a large number of electronic equipment in the cabin to be fixed and installed on the antenna frame of the special equipment. This not only As a result, the weight carried by the antenna load-bearing platform is greatly increased, and it will also cause changes in the working state of the load-bearing platform after the antenna is erected, the transportation state after the antenna...

Problems solved by technology

Chinese patent document CN203950903U discloses a large-scale multi-point support platform, which adopts an arrangement structure of "four leveling legs + eight auxiliary legs" driven by a hydraulic motor, avoiding the complex arrangement and poor balance of a single support structure The problem

[0004] However, compared with four-point automatic leveling, multi-point automatic leveling will prolong the leveling time and increase the leveling complexity. At the same time, after the auxiliary support legs land, it will affect the levelness of the heavy-duty platform, so multi-point (greater than four-point) leveling It also brought challenges to the originally tense leveling accuracy and leveling time
