The invention relates to the technical field of electrical switchgear detection, and discloses a compartment synchronous lifting and unfolding system for switchgear detection, including a compartment top plate, a compartment side plate and a compartment floor, the telescopic column, a side plate adjustment device, a wing The plate adjustment device is driven by hydraulic pressure, and the synchronous lifting and unfolding of the car is realized through the hydraulic synchronous system; the hydraulic synchronous system is controlled by PLC, and the control parameters of the PLC output hydraulic cylinder are transmitted to the proportional valve after D / A conversion and proportional amplifier. The proportional valve controls the moving speed of the hydraulic cylinder by regulating the flow of the hydraulic valve, and the displacement sensor collects the displacement information of each hydraulic cylinder and feeds it back to the PLC, thereby realizing the closed-loop control of the hydraulic synchronization system. The car synchronous jacking and unfolding device used for switchgear detection in the present invention effectively expands the working space inside the car, alleviates the car body stress caused by the asynchronous expansion of the car, and also has high synchronization accuracy, high automation level, and simple operation Etc.
Description
technical field [0001] The invention relates to the technical field of electric switchgear detection, in particular to a carriage 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, w...
