Problems solved by technology

However, in practical applications, the automatic leveling device has the following disadvantages: 1. It is only suitable for pile drivers, and the application range is too narrow
And this automatic leveling device does not have outrigger landing detection, horizontal outrigger, vertical outrigger retraction and other functions, so it is not suitable for mobile carriers
2. At least three level detectors are required
This makes data processing slow, equipment costs are high, and too many inputs make the system redundant

Abstract

The invention relates to a mobile carrier automatic leveling system, belonging to the mechanical-electrical-hydraulic integration technical field, wherein a dual-axis tilt sensor is fixed on a mobile carrier platform; an electric cabinet is fixed on the mobile carrier platform; a pressure sensor is connected with a vertical landing leg; a transverse landing leg is fixed on the mobile carrier platform; the vertical landing leg is connected with the transverse landing leg via a transverse landing leg vertical landing leg connecting member; a bidirectional hydraulic lock is connected between a vertical landing leg electromagnetic valve and the vertical landing leg; the output of a transverse landing leg electromagnetic valve is connected with the input of the transverse landing leg; the output of the dual-axis tilt sensor is connected with the electric cabinet; the output of the pressure sensor is connected with the electric cabinet; and the output of the electric cabinet is connected with the transverse landing leg electromagnetic valve and the vertical landing leg electromagnetic valve. The system enables the leveling of the mobile carrier to achieve speediness, high precision and full automation; meanwhile the system is stable in performance, simple and convenient in operation, strong in universality, comparatively low in cost and capable of meeting the leveling requirements of most mobile carriers.

Description

technical field [0001] The invention relates to a system in the technical field of electromechanical-hydraulic integration, in particular to an automatic leveling system for a mobile carrier, which is used for level adjustment of the mobile carrier. Background technique [0002] In modern national defense and civilian technology, in order to prevent the mobile carrier of heavy equipment from overturning under poor ground conditions, or to provide a stable working platform for heavy equipment, it is often necessary to precisely adjust the mobile carrier of a certain heavy equipment. to the horizontal position. For example, missile launching vehicles, various mobile radar antenna carriages, heavy cranes, etc. must be leveled before work, and the leveling requires fast, accurate and stable. [0003] Traditional manual leveling uses visual and manual methods for rough leveling, or other auxiliary means for secondary adjustment, which has long leveling time, low precision, large...
