Leveling device for work platform of launch vehicle

Abstract

The invention discloses a leveling device for a work platform of a launch vehicle, comprising a host machine, an ECU (Electronic Control Unit), an Ultronics control system, a front left leg cylinder, a front right leg cylinder, a back left leg cylinder and a back right leg cylinder, wherein the leveling device for the work platform of the launch vehicle further comprises an inclination detection device fixed on the work platform via a threaded rod; a cross-shaped mercury tank is arranged in the inclination detection device; a pit is arranged in the center of the mercury tank; mercury is filled in the pit; and four pressure sensors respectively corresponding to the front left leg cylinder, the front right leg cylinder, the back left leg cylinder and the back right leg cylinder are respectively installed on the mercury tank and respectively connected with the ECU via signal lines. The leveling device for the work platform of the launch vehicle has the capabilities of fulfilling a level control process mainly by measuring the gravity change of the mercury and well fulfilling automatic level control, and has the advantages of large driving force and strong load capacity due to the adoption of hydraulic drive.

Description

technical field [0001] The invention relates to a leveling device for an operation platform of a launching vehicle. Background technique [0002] At present, the leveling systems in the engineering field are mainly divided into two categories: manual leveling systems and automatic leveling systems. The automatic leveling system can be divided into two categories according to the different actuators used: electromechanical automatic leveling system and hydraulic automatic leveling system. The manual leveling system mainly uses visual and manual methods for rough leveling, or other auxiliary means for secondary adjustment, which takes a long time for leveling, low precision, large deformation, high repeatability, and low stability; electromechanical automatic leveling The system mostly uses ball screw as the leveling actuator, combined with reducer, photoelectric encoder, servo motor, etc. to form a leg support, but the bearing capacity of the ball screw is not strong, and th...

Problems solved by technology

The manual leveling system mainly uses visual and manual methods for rough leveling, or other auxiliary means for secondary adjustment, which takes a long time for leveling, low precision, large deformation, high repeatability, and low stability; electromechanical automatic leveling The system mostly uses ball screw as the leveling actuator, combined with reducer, photoelectric encoder, servo motor, etc. to form a leg support, but the bearing capacity of the ball screw is not strong, and the driving force of the system is small, so It is not suitable for heavy-duty mobile carriers, but only suitable for mobile carriers with lighter loads; the hydraulic automatic leveling system mainly uses hydraulic cylinders as actuators, and adopts hydraulic drive, which has large driving force and strong load capacity, but the speed displacement of the hydraulic cylinders Feedback is relatively complex, and it is difficult to realize automatic control
