An anti-tipping safety protection method for a swing platform with a high center of gravity

Abstract

The invention relates to an anti-tilting safety protection method for a swing table with a high gravity center, and belongs to the technical field of swing tables. According to the anti-tilting safety protection method, a hydraulic protection device is combined with computer control; according to the hydraulic protection device, a hydraulic control unidirectional valve is arranged on an oil inlet / outlet path of a longitudinal and transverse swing driving hydraulic oil cylinder for driving the swing table with the high gravity center to swing, so that tilting of a swing table body in the case of sudden power failure is prevented; the hydraulic control unidirectional valve is controlled by pressure control oil and can be opened certainly when the swing table works; when the swing table suddenly stops, the hydraulic oil path is unloaded, and a valve core of a servo valve is controlled to slowly reset to a zero position by a stop control signal provided by a computer, so that the swing table body is not tilted; and when system pressure is completely unloaded, the hydraulic control unidirectional valve is controlled to close, and the swing table can be stopped steadily. The anti-tilting safety protection method has the advantages of simple structure, effectiveness in control, convenience in operation, good economical and practical effect, practicability, safety, stability and the like.

Description

technical field [0001] The invention belongs to the technical field of leakage detection, in particular to an anti-tipping safety protection method for a high-center-of-gravity swaying platform. Background technique [0002] At present, the existing high-center-of-gravity swing test bench has the advantages of compact structure, small footprint under the same load capacity, and convenient movement. However, since its center of gravity is above the vertical and horizontal swing axes, if no safety protection measures are taken, if an emergency occurs during the swing process, the driving force will be lost during emergency shutdown, causing the platform to tip over, which will easily cause impact on the equipment under test. , leading to technical problems such as damage to the equipment under test. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides an anti-tipping safety protection method for ...
