Problems solved by technology

[0005] The purpose of the present invention is to provide a cargo loading and unloading method based on the stowage factor. By introducing the reference data of the stowage factor, it not only avoids the situation that the single bucket is light or overloaded due to the inappropriate grab bucket model, and the bucket is changed. Moreover, the grab model with the highest efficiency can be selected for operation, which improves the operating efficiency of the ship from two aspects, and solves the problem that the stowage factor is not used to improve the loading and unloading operation efficiency of the bulk cargo terminal in the prior art, and the traditional loading and unloading operation method is still used , the problem of heavy workload and low efficiency

Embodiment 1

[0036] This embodiment provides a cargo loading and unloading method based on the stowage factor, which specifically includes the following steps:

[0037] S1: Obtain the stowage factor of the cargo-laden ship through high-frequency contact, and calculate the weight of the single bucket of the cargo based on the stowage factor of the cargo and the existing grab bucket capacity of the wharf before the ship arrives at the port. , the calculation formula is:

[0038] Single bucket weight t = grab bucket capacity m 3 ÷ stowage factor m 3 / t; (1)

[0039] S2: Obtain the rated load capacity of the cargo-carrying vessel and the weight of the loading and unloading grab bucket, and obtain the rated capacity of the grab bucket through the following formula, the calculation formula is:

[0040] Rated load capacity t = rated capacity of grab bucket t - grab bucket dead weight t; (2)

[0041] S3: The single bucket weight t and the rated capacity value of the grab bucket obtained from S...

Embodiment 2

[0050] This embodiment provides a cargo loading and unloading method based on the stowage factor, which specifically includes the following steps:

[0051] S1: Obtain the stowage factor of the cargo-laden ship through high-frequency contact, and calculate the weight of the single bucket of the cargo based on the stowage factor of the cargo and the existing grab bucket capacity of the wharf before the ship arrives at the port. , the calculation formula is:

[0052] Single bucket weight t = grab bucket capacity m 3 ÷ stowage factor m 3 / t; (1)

[0053] S2: Obtain the rated load capacity of the cargo-carrying vessel and the weight of the loading and unloading grab bucket, and obtain the rated capacity of the grab bucket through the following formula, the calculation formula is:

[0054] Rated load capacity t = rated capacity of grab bucket t - grab bucket dead weight t; (2)

[0055] S3: The single bucket weight t and the rated capacity value of the grab bucket obtained from S...

Embodiment 3

[0064] This embodiment provides a cargo loading and unloading method based on the stowage factor, which specifically includes the following steps:

[0065] S1: Obtain the stowage factor of the cargo-laden ship through high-frequency contact, and calculate the weight of the single bucket of the cargo based on the stowage factor of the cargo and the existing grab bucket capacity of the wharf before the ship arrives at the port. , the calculation formula is:

[0066] Single bucket weight t = grab bucket capacity m 3 ÷ stowage factor m 3 / t; (1)

[0067] S2: Obtain the rated load capacity of the cargo-carrying vessel and the weight of the loading and unloading grab bucket, and obtain the rated capacity of the grab bucket through the following formula, the calculation formula is:

[0068] Rated load capacity t = rated capacity of grab bucket t - grab bucket dead weight t; (2)

[0069] S3: The single bucket weight t and the rated capacity value of the grab bucket obtained from S...

Abstract

The invention discloses a cargo loading and unloading method based on a stowage factor. The cargo loading and unloading method specifically comprises the following steps that S1, the stowage factor ofa cargo-carrying ship is obtained in a mode of high-frequency contact or request, through the obtained stowage factor, the cargo single-bucket weight can be calculated before the ship arrives at a port according to the cargo stowage factor and the existing grabbing bucket capacity of a wharf, and as for the calculating formula, the single-bucket weight t=grabbing bucket capacity m<3> / stowage factor m<3> / t; and S2, the rated loading capacity of the cargo-carrying ship and the weight of a cargo loading and unloading grabbing bucket are obtained, and the rated capacity of the grabbing bucket isobtained through the following calculation formula that the rated loading capacity t=grabbing bucket rated capacity t-grabbing bucket weight t. According to the cargo loading and unloading method, thereference data of the stowage factor are introduced, the situation that the model of the grabbing bucket is not proper, consequently, the single bucket weight is small or the single bucket is overloaded, and the bucket is replaced is avoided, the grabbing bucket model with the highest efficiency can be selected for operation, and thus the ship operation efficiency is improved from two aspects.

Description

technical field [0001] The invention relates to the technical field of measuring cargo loaded on ships, in particular to a cargo loading and unloading method based on a stowage factor. Background technique [0002] Bulk cargo transportation plays an important role in modern transportation methods, especially iron ore-based bulk cargo transportation, which shows a large-scale and high-speed growth trend year by year, which is both an opportunity and a challenge for bulk cargo terminals; If the cargo terminal cannot improve its own operating efficiency, it will prolong the berthing time of the ship and reduce the competitiveness of the terminal. In today's increasingly fierce homogenization competition, if the efficiency cannot be improved, it will not be able to attract customers' ships to berth, which will lead to the company's interests. Improving the loading and unloading efficiency of ore ships is the key to improving the overall operating efficiency of the terminal. [...
