The invention relates to the technical field of electrical switch cabinet detection, and discloses a carriage synchronous jacking and unfolding system for switch cabinet detection, which comprises a carriage top plate, carriage side plates and a carriage bottom plate, and is characterized in that telescopic stand columns, side plate adjusting devices and wing plate adjusting devices are hydraulically driven, and synchronous jacking and unfolding of a carriage are realized through a hydraulic synchronous system; and the hydraulic synchronization system is controlled by a PLC, control parameters of hydraulic cylinders output by the PLC are transmitted to a proportional valve through D / A conversion and a proportional amplifier, the proportional valve controls the moving speed of the hydraulic cylinders by regulating and controlling the flow of the hydraulic valves, a displacement sensor collects displacement information of the hydraulic cylinders and feeds back the displacement information to the PLC, and therefore closed-loop control over the hydraulic synchronization system is achieved. The compartment synchronous jacking and unfolding device for switch cabinet detection effectively expands the working space in the compartment, relieves compartment stress generated by asynchronous compartment expansion, and has the advantages of being high in synchronization precision, high in automation level, easy to operate and the like.
Description
technical field [0001] The invention relates to the technical field of electric switchgear detection, in particular to a compartment synchronous jacking and unfolding system for switchgear detection. Background technique [0002] During the production process of the switchgear, some defects will inevitably occur due to the influence of equipment, environment, human factors and other factors. In addition to not being able to play a good role in the isolation and protection of the switchgear, these defects may also have a negative impact on the power grid, thereby causing accidents. During the work, it is necessary to carry out daily maintenance, primary maintenance, secondary maintenance, and routine maintenance of incoming line switches for high and low voltage power distribution cabinets. [0003] In order to ensure the safety of the work, it is necessary to carry out product inspection on the switchgear. The use of the inspection vehicle realizes the inspection and travel...
