Problems solved by technology

[0004] In order to solve the problems of low leveling efficiency and long leveling time in the existing four-leg launch vehicle chassis leveling method, the present invention innovatively provides a four-leg launch vehicle chassis leveling method. The leveling method completes the leveling of the launching vehicle chassis by judging and adjusting the center of gravity of the chassis, and using a combination of single-leg adjustment and double-leg adjustment, thereby avoiding the conventional problem of relying on experience to adjust the legs one by one; therefore, The invention effectively reduces the leveling time and improves the leveling efficiency

Embodiment Construction

[0035] The leveling method of the four-leg launching vehicle chassis of the present invention will be explained and illustrated in detail below in conjunction with the accompanying drawings.

[0036] Such as Figures 1 to 6 As shown, the present invention discloses a method for leveling the chassis of a launching vehicle with four legs. The method is a method for dynamically leveling the chassis of a launching vehicle. Specifically, the leveling method includes the following steps.

[0037] Step 1, control the launching vehicle to extend the four outriggers at the same time, and make the four outriggers reach the expected height; specifically, in this embodiment, after the four outriggers are extended, judge whether the four outriggers have reached the expected height height, if yes, go to step 2; if not, control the outriggers that have not reached the expected height to continue to stretch out, and repeatedly execute height judgment until the expected height is reached.

Abstract

The invention discloses a four-supporting-leg launch vehicle chassis leveling method. The leveling method includes steps: step 1, controlling a launch vehicle to extend four supporting legs to an expected height at the same time; step 2, acquiring the position of a gravity center of a launch vehicle chassis, judging whether the gravity center of the launch vehicle chassis is positioned at an origin of a pre-established coordinate system or not, if yes, executing a step 5, and if not, executing a step 3; step 3, on a coordinate plane, judging a quadrant of the gravity center; step 4, accordingto the quadrant of the gravity center, sequentially performing single-supporting-leg adjustment operation and double-supporting-leg adjustment operation to make the gravity center at the origin of thecoordinate system; step 5, completing leveling of the four-supporting-leg launch vehicle chassis. The method has advantages that leveling time of the four-supporting-leg launch vehicle chassis is effectively shortened, leveling efficiency is substantially improved, and accordingly launch vehicle operation task completion is supported reliably.

Description

technical field [0001] The invention relates to the technical field of chassis leveling of special vehicles, and more specifically, the invention relates to a method for leveling the chassis of a four-leg launching vehicle. Background technique [0002] At present, the conventional method for leveling the chassis of the launcher with four legs is manual manual hydraulic leveling. However, the leveling of the launch vehicle chassis has very high requirements on the speed of the leveling action, while the conventional leveling method is to adjust each leg one by one, which relies heavily on the experience of the operator, and often has long leveling time and poor leveling efficiency. Inferior question. Although some people try to adopt the method of automatic leveling, due to problems such as improper leveling method and unreasonable scheme design, not only the leveling efficiency has not been significantly improved, but the leveling accuracy cannot be guaranteed.
