The work aims to propose a design scheme of a new multi-functional FIBC inspection device in order to solve the problems of low accuracy, poor stability and low efficiency of the current FIBC top lifting test device. Combined with the diversity of the structure and lifting methods of the FIBC lifting components, the optimal design was adopted to realize the combined design of double-suspension device and double-pressurizing device in the new device. The new device could adjust the pressure state arbitrarily, realizing the flexible switching of the working mode of the FIBC top lifting test through single-point and multi-point lifting methods and feeding back the stress of the entire FIBC and any lifting components accurately. Three groups of different types of FIBC were selected for top lifting test randomly. Each group of FIBC was tested 90 times. The pressure-time test curve was relatively stable, with a success rate of 96.67%, which fully met the requirements of the accuracy and the stability of the test data. The device has a stable working state and high versatility, distributes the test load accurately, ensures the accuracy of the test data, and can take into account the test requirements of multiple design types of FIBC, thus improving the inspection quality and efficiency effectively.
