Automatic leveling system for vehicle body platform

Abstract

The invention relates to the technical field of leveling systems, and discloses an automatic leveling system for a vehicle body platform. The automatic leveling system comprises a horizontality detection element, travel sensors and a programmable controller, wherein the horizontality detection element is arranged on the vehicle body platform; a lifting oil cylinder of a vehicle body platform hydraulic lifting system is divided into four groups according to areas in which four angles of the vehicle body platform are positioned; each group of lifting oil cylinder is provided with a travel sensor; and the programmable controller is connected with control valves of all the groups of lifting cylinders, the horizontality detection element and the travel sensors respectively. In the automatic leveling system, signals transmitted from the travel sensors and the horizontality detection element are subjected to operation processing through the programmable controller; when inclined, the vehiclebody platform can be appropriately leveled in time, so that the horizontality and the stability of the vehicle body platform are ensured, and vibration generated by overregulation is prevented; and various real-time regulation modes are provided, so that a driver can select the regulation modes as required according to actual road surface conditions. The system is simple, practical, safe and reliable, and has low cost and a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of leveling systems, and is mainly applicable to leveling mobile carriers. Background technique [0002] At present, most of the hydraulic lifting systems used in hydraulic self-propelled transportation simply realize the rise and fall of the body platform, and have not yet made real-time adjustments according to the actual conditions of the road surface to maintain the level of the body platform. It is the transportation of heavy objects with a high center of gravity on uneven road conditions, especially irregular large-scale transportation. If proper leveling is not carried out according to the road conditions, it is easy to cause the transported heavy objects to slip because the body platform is not on the horizontal plane. , overturning and other accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic leveling system for the...
