Automatic leveling system of multipoint electric support platform

Abstract

The invention refers to an automatic leveling system of a multipoint electric support platform. The automatic leveling system of a multipoint electric support platform has advantages that the lifting weight is heavy; the stress distributes evenly and is controllable; the electric support performing mechanism touches the ground rapidly and reliably; the repetitiveness of the leveling precision is fine; the precision is high; the system is safe and convenient; the maintenance is convenient; the system information is visible; and the electric wiring is simple. In the system, a CAN bus network is arranged for controlling a leveling servo motor to move; a leveling display and control cabinet forms a control and display centre of the whole system working state, data and system fault codes via the control program software and hard ware drive program software arranged by a central digital controller; the central digital controller and the leveling display and control cabinet connected to the central digital controller together with an intelligent control box form closed loop control which performs mechanism grounding control, location control and gradient control to the support legs of the system leveling platform. The system has fine repetitiveness, stable working, high leveling precision, complete safety protection measures and convenient and reliable establishment and displacement.

Description

technical field [0001] The invention relates to a multi-point support leveling system, in particular to a multi-point support platform leveling system applied to high-precision, large-load, multi-axis platforms and vehicle-mounted equipment with special requirements. The multi-point electric automatic leveling system involved in the description of the present invention is a multi-point support leveling system based on vehicle-mounted equipment, but it can be considered that the leveling system involved in the description of the present invention can also be applied to other various Leveling of other platforms with multiple pivots that require leveling. Electric automatic leveling systems such as mining excavators, vehicle satellite TV receivers, bridge erection equipment, medical testing platforms, and missile launch vehicles Background technique [0002] Many movable devices in the prior art generally have a level requirement on the installation surface of the device when ...

AI Technical Summary

Problems solved by technology

[0003] 1 Internationally, since the external leakage and internal leakage of the hydraulic system have not been resolved so far, the system still has the problem of poor long-term stability

[0004] 2. The hydraulic system used in the maintenance has high requirements on the environment, and the pollution brought by the oil can easily lead to the blockage of the solenoid valve, making the system unable to work normally

[0005] 3 The RC controller used in this system is a non-intelligent controller, without safety protection design, which is a defect that endangers the safety of personnel and equipment for a mechanica...
