Description

Technical Field

[0001] The present invention relates to the technical field of ship loading operations, and in particular to a fixed ship loading system and a ship loading method. Background Art

[0002] Ship loaders are large bulk materials machinery used for loading at bulk material terminals. With the rapid development of modern marine transportation, large ship loaders have gradually become important loading and conveying equipment at bulk material terminals. There are many types of ship loaders, which can generally be summarized into two categories: fixed ship loaders and mobile ship loaders. Among them, fixed ship loaders generally use belt conveyors. Fixed belt conveyors are widely used in metallurgy, mining, coal, ports, hydropower, and chemical industries due to their simple structure, convenient maintenance, low cost, strong versatility, and small amount of hydraulic engineering. However, since fixed ship loaders are difficult to move, change amplitude, and telescope within the length of the ship, the loading area covered is small. When loading, ship transfer operations are required, and continuous loading cannot be achieved, resulting in low loading efficiency. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the fixed loader is difficult to realize movement, amplitude change and extension within the length of the ship, the covered loading area is small, and the ship moving operation is required during loading, and continuous loading cannot be realized, resulting in low loading efficiency.

[0004] In order to solve the above problems, the present invention provides a fixed ship loading system, comprising: At least two fixed ship loaders are arranged at intervals and are disposed at the port, wherein the fixed ship loaders are suitable for loading bulk materials into a bulk ship; the bulk ship is docked at the port along its length direction; A first conveyor connected to all the fixed ship loaders; the first conveyor is suitable for conveying bulk materials to the feed port of any fixed ship loader; The second conveyor is provided with a material dividing device at the end thereof. The second conveyor is suitable for conveying bulk materials to the port and unloading the bulk materials to the feed port of a fixed ship loader and the first conveyor close to the above-mentioned fixed ship loader through the material dividing device.

[0005] Optionally, the stationary ship loader comprises: a first stationary ship loader and a second stationary ship loader; an end of the second conveyor is located directly above a feed port of the first stationary ship loader.

[0006] Optionally, the material dividing device is connected to the feed port of the first fixed ship loader through a first chute structure, and the material dividing device is connected to the first conveyor through a second chute structure.

[0007] Optionally, the stationary ship loader comprises: A discharge arm is provided with a ship loading chute at the outer end of the discharge arm, and the ship loading chute is suitable for discharging bulk materials onto a bulk ship.

[0008] Optionally, the fixed ship loader further comprises: A rotating mechanism is connected to the discharge arm, and the rotating mechanism is suitable for driving the discharge arm to rotate around the inner end of the discharge arm so that the loading chute covers an area within a set radius on the bulk ship.

[0009] Optionally, the fixed ship loader further comprises: A telescopic mechanism is connected to the unloading arm, and the telescopic mechanism is suitable for driving the unloading arm to be telescopic so that the loading chute covers an area range along the width direction of the bulk ship.

[0010] Optionally, the first conveyor and the second conveyor are both belt conveyors.

[0011] Optionally, a portion of the first conveyor located adjacent to the fixed ship loader is supported and fixed by a supporting tower.

[0012] Optionally, the intervals between adjacent fixed ship loaders are determined according to the type and length of the bulk ship, and the total loading range of all fixed ship loaders covers the length of the bulk ship.

[0013] The present invention also provides a fixed ship loading method, using the fixed ship loading system, comprising: The bulk material is conveyed to the port by means of a second conveyor; The bulk material is discharged to a feed inlet of a fixed ship loader and a first conveyor close to the fixed ship loader by a material distribution device; The above-mentioned fixed ship loader discharges the bulk material onto the bulk ship, and at the same time, the bulk material is conveyed to the feed port of other fixed ship loaders through the first conveyor; Other stationary ship loaders unload bulk materials onto bulk ships.

Moreover, unlike the mobile ship loader configuration, the technical solution of this application does not need to lay tracks throughout the entire wharf surface, and does not need to set up a wharf surface, which greatly reduces the workload of civil construction such as wharf pile foundation, foundation, revetment and wharf platform, and effectively reduces the project cost.
