Description

Technical Field

[0001] The present disclosure relates to the technical field of ship unloaders, and in particular to a transport device and a screw ship unloader. Background Art

[0002] Ship unloaders can be used for unloading operations of various bulk materials such as coal, fertilizers and chemical raw materials. They have the advantages of dust-free unloading, high production efficiency, light weight and small size. When the ship unloader is working, it is necessary to use a transportation device to identify and locate the hatch of the bulk carrier and the materials in the cabin. At present, the laser scanners of ship unloaders are mostly set on the horizontal arms of the ship unloaders. However, in some ship unloaders where the horizontal arm needs to be lowered so that the material head can enter the cabin to retrieve materials, such as screw ship unloaders, this setting method of the laser scanner may cause the scanning area of the laser scanner to be affected and it itself is easy to collide with the other structures of the ship unloader, causing safety accidents.

[0022] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0023] In this disclosure, unless otherwise specified, directional terms such as "inside" and "outside" refer to the "inside" and "outside" relative to the outline of the corresponding component itself. In addition, the terms "first" and "second" used in this disclosure are intended to distinguish one element from another and do not have sequential or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate this disclosure and should not be understood as limiting this disclosure.

[0024] The transport device and the screw ship unloader in exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0025] like Figures 1 to 3 As shown, the first aspect of the present disclosure provides a transport device that can be used for a ship unloader, comprising a vertical arm 1, a feeding mechanism 2, and a laser scanner 3, wherein the feeding mechanism 2 is arranged parallel to the vertical arm 1 and connected to the vertical arm 1; the laser scanner 3 is arranged in the vertical arm 1 and at least two laser scanners 3 are arranged on two opposite inner walls of the vertical arm 1, for scanning the workpieces to be scanned outside the vertical arm 1. When the ship unloader is operating, the laser scanner 3 arranged in the vertical arm 1 can, on the one hand, perform a relatively comprehensive scanning operation on the workpieces to be scanned outside the vertical arm 1; on the other hand, because it is arranged in the vertical arm 1, even when the vertical arm 1 is moving, the laser scanner 3 will not collide with other structures on the ship unloader or be damaged by the influence of a harsh environment, thereby ensuring the use efficiency and service life of the transport device.

[0026] In the embodiments of the present disclosure, Figures 1 to 3As shown, the vertical arm 1 may include a first connecting side 110, and the feeding mechanism 2 includes a second connecting side 210 connected to the first connecting side 110. The projections of the first connecting side 110 and the second connecting side 210 in the first direction A partially overlap. The inner sidewall of the first connecting side 110 in the area not overlapping with the second connecting side 210 in the first direction A, as well as the remaining inner sidewall of the vertical arm 1 in the circumferential direction, form a mounting position for the laser scanner 3. The connection between the first connecting side 110 of the vertical arm 1 and the second connecting side 210 of the feeding mechanism 2 can ensure a connection area between the two, thereby improving the stability of the connection. In addition, because the projections of the two in the first direction A partially overlap, when the laser scanner 3 within the vertical arm 1 is located on the inner wall of the first connecting side 110, it can scan the workpiece to be scanned outside the vertical arm 1 through the non-overlapping area between the first connecting side 110 and the second connecting side 210, thereby preventing the feeding mechanism 2 connected to the vertical arm 1 from affecting the area scanned by the laser scanner 3.

[0027] Specifically, if Figures 1 to 3 As shown, there can be two laser scanners 3, which are respectively disposed on the inner sidewall of the first connection side 110 and the inner sidewall opposite to the first connection side 110. The two laser scanners 3 disposed opposite each other on the inner wall of the vertical arm 1 can protect the laser scanner 3 from damage by the external environment or other structures while ensuring the scanning range of the laser scanner 3 and improving work efficiency.

[0028] Among them, the vertical arm 1 can be constructed as a rectangular column structure, which can facilitate the installation of the laser scanner 3 and facilitate connection with the feeding mechanism 2, and the feeding mechanism 2 can be constructed as a cylindrical structure to adapt to the structure of the feeding mechanism 2. For example, the feeding mechanism 2 can be configured as a spiral feeding mechanism.

[0029] In addition, it should be noted that although the partial overlapping area between the first connection side 110 of the vertical arm 1 and the second connection side 210 of the feeding mechanism 2 will interfere with the scanning range of the laser scanner 3 to a certain extent, when the angular range of the laser scanner 3 is large enough, the above-mentioned overlapping area will not affect the scanning results of the laser scanner 3, and the scanning range of the laser scanner 3 can still meet the application requirements on site.

[0030] In addition, the laser scanners 3 can be configured in different quantities or set in different installation positions according to needs. For example, there are still two laser scanners 3, and the two laser scanners 3 are relatively arranged on the other inner walls of the vertical arm 1; or there are four laser scanners 3, and the four laser scanners 3 are respectively arranged on different inner walls of the vertical arm 1. As long as the number and position settings of the laser scanners 3 can ensure that the laser scanners 3 can perform a comprehensive scan of the scanned object, it can be sufficient.

[0031] In some embodiments, as Figures 1 to 3 As shown, a scanning port can be formed on the circumferential sidewall of the vertical arm 1, allowing the laser scanner 3 inside the vertical arm 1 to scan the object to be scanned through the scanning port. The shape of the scanning port can be set to any size and shape as needed, as long as it ensures that the laser scanner 3 can scan the object to be scanned. Of course, to further enhance the protection provided by the vertical arm 1 for the laser scanner 3, the scanning port can be equipped with a transparent protective member, such as protective glass of a thickness and transparency sufficient to ensure the normal operation of the laser scanner 3.

[0032] In the embodiments of the present disclosure, Figures 1 to 3 As shown, the feeding mechanism 2 may include a first end 220 and a second end 230 disposed opposite each other. The first end 220 is used for retrieving materials, and the second end 230 is used for connecting to the horizontal beam of the ship unloader. The laser scanner 3 is located on the side of the vertical arm 1 near the first end 220. In other words, the laser scanner 3 is positioned closer to the workpiece to be scanned, thereby significantly improving the recognition effect of the laser scanner 3 on the workpiece to be scanned and enhancing positioning accuracy.

[0033] In addition, if Figures 1 to 3 As shown, the length of the feeding mechanism 2 in the second direction B can be greater than the length of the vertical arm 1. In this way, the vertical arm 1 will not interfere with the feeding mechanism 2 while the feeding mechanism 2 is transporting materials.

[0034] In some embodiments, as Figures 1 to 3 As shown, the vertical arm 1 is further provided with a positioning pin 4 for positioning the laser scanner 3. The positioning pin 4 can determine the precise position of the laser scanner 3 within the vertical arm 1, thereby quickly calibrating the Cartesian coordinate system origin coordinates and Euler angles of the laser scanner 3, thereby improving the scanning accuracy of the laser scanner 3 and greatly improving the calibration efficiency.

[0035] In the embodiments of the present disclosure, Figures 1 to 3 As shown, the feeding mechanism 2 can be configured as a screw feeding mechanism. The screw feeding mechanism has a high conveying efficiency and can complete the unloading of a large amount of materials in a short time, thereby improving the unloading efficiency. In addition, the screw unloading mechanism has a compact design and does not require a large installation space, which can reduce the space occupied by the ship unloader.

[0036] The second aspect of the present disclosure provides a screw ship unloader, comprising the above-mentioned transport device. It should be noted that the screw ship unloader has all the beneficial effects of the above-mentioned transport device, which will not be described in detail in this disclosure.

[0037] In summary, the present disclosure exemplarily illustrates the working process of the transport device and the screw unloader.

[0038] When the screw ship unloader is working, the two oppositely arranged laser scanners 3 located in the vertical arm 1 can scan the parts to be scanned. During this process, even if the vertical arm 1 and the feeding mechanism 2 are appropriately adjusted according to the position of the material to move to a suitable working position, the laser scanner 3 located in the vertical arm 1 will not be damaged by collisions with other structures on the ship unloader or the influence of harsh environments, thereby ensuring the utilization efficiency and service life of the transportation device. In addition, the two oppositely arranged laser scanners 3 can also perform relatively comprehensive scanning of the parts to be scanned outside the vertical arm 1 as much as possible.

[0039] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0041] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
