The invention relates to a liquid hydrogen tank car loading, unloading and weighing device. The liquid hydrogen tank car loading, unloading and weighing device comprises a horizontal bearing plate, vertical balance rods, a horizontal connecting structure, a supporting balance structure, pulleys, a weight balance table, pressure sensors, an air compressor, horizontal bearing plate pneumatic locating devices, vertical balance rod pneumatic locating devices, weight balance table pneumatic locating devices, reset unloading force buffer supporting blocks, reset anti-collision buffer blocks, emergency protection buffer blocks and balancing weights. The horizontal bearing plate, the vertical balance rods and the horizontal connecting structure are connected and fixed into a whole from top to bottom. The supporting balance structure is mainly composed of an inner supporting balance structure, an outer supporting balance structure and a bottom supporting structure. The liquid hydrogen tank carloading, unloading and weighing device has the beneficial effects that through the balance principle of the pulleys and the combined form of the weight balance table and the balancing weights, the range section can be correspondingly shortened effectively according to the weight of a liquid hydrogen tank car so as to adopt small-range and high-precision sensors, and the weighing precision to the liquid hydrogen net weight is improved.
Description
technical field [0001] The invention relates to a weighing device, in particular to a weighing device and method for loading and unloading a liquid hydrogen tank truck. Background technique [0002] At present, with the increasingly serious energy crisis and environmental crisis, hydrogen energy is the most ideal energy source for human beings in the future due to its advantages of cleanliness and pollution-free, and it has attracted more and more attention from all countries in the world. At present, there are still many problems to be solved in the development of domestic hydrogen energy infrastructure industry, one of which is the efficient transportation of hydrogen. Liquid hydrogen has the advantages of low transportation cost, high hydrogen storage purity, and low-pressure storage. It is an ideal way to solve the large-scale and commercial storage, transportation and supply of hydrogen. [0003] At present, liquid hydrogen tank trucks are generally used for liquid hyd...
