Description
Technical Field
The invention relates to the technical field of load factor tests, in particular to an automatic load factor test system which is humanized and high in efficiency.
Background
The loading factor refers to the space (cubic meters or cubic feet) taken up by each ton of cargo normally stacked in the cargo hold, or how many tons of cargo a given cargo hold volume can be loaded with. The loading factor is important cargo data in the ship loading work and is used for calculating the cargo hold volume of certain cargo with certain weight.
The loading factor of the cargo is a very important data in the loading job. In water transport, the volumes of the cargoes with equal weights sometimes vary greatly due to the weight of the cargoes and the different packing dimensions. Such as pig iron and cotton, if fully loaded with pig iron, the hold is still much empty when the ship load is full, resulting in a ship deficit (brooken hold); in contrast, if cotton is fully loaded, the entire bilge of the ship is filled, but the load capacity remains much, resulting in a ship's loss of load.
The loading factor of a good is the volume of the good (the measured volume of the good) per ton of weight, i.e. the ratio of the volume of the good to the weight. The loading factor of cargo is an important performance indicator that indicates the weight of cargo.
The cargo loading factor varies depending on the type of cargo, the place of origin, the shipping mode on the ship, and the like. For example, the stacking factor of the iron ore sand is 0.31-0.53 when in bulk transportation, the stacking factor of the wheat is 1.32-1.34 when in bulk transportation, and the stacking factor of the wheat is 1.34-1.45 when in package transportation.
Goods with small accumulation and cutting factors, such as iron ore sand, phosphate, bauxite and the like, belong to heavy goods, and the requirement of the heavy goods on the bilge of the ship is low. Goods with large accumulation factors, such as grains, cotton yarns, cloth, tea, tobacco and the like, belong to light goods, and the light goods have high requirements on cabin capacity. The factor of the backlog is an important basis for the requirements of the hold capacity of the transport vessel, which are specified in the technical task book of the vessel design.
The loading factor of heavy goods is small, the requirement on the hold capacity of the ship is low, and the factor controlling the main factors of the ship is weight (loading capacity). The topside of the heavy cargo ship meets the international load line convention) or the minimum side required by the national sea ship load line standard, and the corresponding depth enables the cargo hold capacity of the ship to meet the requirement of the cargo on the volume. Heavy cargo vessels are the smallest topsides vessel of the payload capacity.
The loading factor of the light cargo is large, the cargo hold capacity requirement of the ship is high, the factor controlling the main factors of the ship is the volume, the cargo hold capacity of the ship can not meet the requirement of the cargo on the volume according to the minimum topside determination (the cargo loading factor p is more than 1.410 in general). The topside of the light cargo ship is greater than the minimum topside.
In summary, it is very important to accurately grasp the cargo accumulation factor reflecting the relationship between the cargo volume and the weight, and to correctly formulate the allocation accumulation plan.
The existing loading factor tester is special equipment for testing the loading factor of bulk cargo to analyze the hold capacity requirement of the cargo hold. The test of the equipment can be used for judging whether the bulk cargo meets the requirements of International load line convention or sea vessel load line Specification in China, and meanwhile, the conversion of different units can be carried out by combining with a accumulation factor conversion table in International maritime solid bulk cargo rule (IMSBC Code). However, the equipment has high personnel participation, high labor capacity and low measurement efficiency.
Therefore, a humanized and efficient automatic loading factor test system is needed.
