Description

Technical Field

[0001] This utility model relates to the technical field of laser scanning devices for ship loaders, specifically a laser scanning device for loading and unloading bulk cargo at a terminal. Background Technology

[0002] At bulk cargo terminals, ship loaders and ship unloaders are key equipment for loading and unloading. Currently, there are many successful cases of remote fully automatic control and on-site unmanned operation of ship loaders and ship unloaders. Among them, three-dimensional modeling of the ship's hold and internal materials is the key to fully automatic control of loading and unloading. At present, laser scanning devices are the mainstream equipment for three-dimensional modeling, with the characteristics of high precision, high reliability and strong environmental adaptability. Since the laser scanning coverage of a single laser scanning device is limited, multiple laser scanning devices are usually fixedly combined and installed at the cantilever head of the ship loader and ship unloader to better cover the ship's hold and internal materials.

[0003] Currently, most ship loader laser scanning devices require multiple laser scanners, which increases the difficulty of 3D modeling. The 3D modeling process requires converting the point cloud data of the laser scanning device from the local coordinate system to the global coordinate system of the terminal. At the same time, different laser scanning devices have different spatial orientations, making it difficult to obtain relevant information about bulk cargo stably and accurately, which cannot meet the needs of efficient and precise loading and unloading operations in modern bulk cargo terminals. Therefore, we propose a laser scanning device for loading and unloading at bulk cargo terminals. Utility Model Content

It solves the problems that most current ship loader laser scanning devices require multiple laser scanners, which increases the difficulty of 3D modeling. The 3D modeling process requires converting the point cloud data of the laser scanning devices from the local coordinate system to the global coordinate system of the terminal. At the same time, different laser scanning devices have different spatial orientations, making it difficult to stably and accurately obtain relevant information about bulk cargo, thus failing to meet the needs of efficient and precise loading and unloading operations at modern bulk cargo terminals.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser scanning device for loading and unloading bulk cargo terminals, comprising an installation assembly and a laser scanner. The installation assembly is fixedly equipped with a left-right adjustment device and a right-down adjustment device. The installation assembly includes an L-shaped installation plate.

The second driving helical gear is connected to a rotating shaft and a driving bevel gear via a second driven helical gear.

[0006] Furthermore, the left and right adjustment device includes a first motor fixedly installed on the surface of the right mounting bracket. The output end of the first motor is fixedly installed with a first driving helical gear through a first rotating shaft. The first driving helical gear is connected to a rotating column and a U-shaped frame through a first driven helical gear. The U-shaped frame is connected to a driven bevel gear and a connecting block through a rotating rod. An extension rod is fixedly installed on one side of the connecting block, and the laser scanner is fixedly installed at the end of the extension rod away from the connecting block.

[0007] Furthermore, fixing ears are fixedly installed on both the front and rear surfaces of the horizontal plate of the L-shaped mounting plate, and the surfaces of both sets of fixing ears are provided with first mounting holes.

[0008] Furthermore, two sets of reinforcing ribs are fixedly installed inside the L-shaped mounting plate, and two sets of locking ears are fixedly installed on both sides of the vertical plate of the L-shaped mounting plate.

[0010] Furthermore, the rotating shaft is rotatably connected to the inside of the rotating column, and the upper end of the rotating shaft passes through the U-shaped frame.

[0011] Furthermore, the driving bevel gear is fixedly installed on the top of the rotating shaft and located inside the U-shaped frame, and the driving bevel gear is meshed with the driven bevel gear.

[0014] This utility model provides a laser scanning device for loading and unloading bulk cargo terminals, which has the following advantages:

[0015] 1. By coordinating the left-right adjustment device and the up-down adjustment device, a multi-dimensional adjustment system is constructed. In the left-right adjustment device, the first motor drives the first rotating shaft and the first active helical gear, which in turn drive the U-shaped frame and the laser scanner to rotate left and right via the first driven helical gear and the rotating column. In the up-down adjustment device, the second motor, with the help of the second rotating shaft and the second active helical gear, drives the laser scanner to deflect up and down via the second driven helical gear, the rotating shaft, the active bevel gear, and the driven bevel gear. This multi-dimensional adjustment allows the laser scanner to cover different angles of the bulk cargo terminal loading and unloading area, accurately capture cargo information, improve the comprehensiveness and accuracy of scanning, and ensure long-term stable operation of the device by the long-term maintenance of the gear transmission, thus reducing operation and maintenance costs.

[0016] 2. The L-shaped mounting plate can be quickly positioned with the terminal facilities through the fixing ears and the first mounting hole. The locking ears and the second mounting hole strengthen the vertical fixation, adapting to different installation scenarios. The internal reinforcing ribs improve the structural strength and resist the vibration and impact during terminal operations, ensuring the overall stability of the device and making the left and right adjustment device, the up and down adjustment device and the laser scanner operate more reliably. The L-shaped mounting plate integrates a programmable logic controller (PLC). After being electrically connected to the laser scanner, it can accurately control its scanning frequency, start and stop and data transmission. In conjunction with the motor action of the left and right adjustment device and the up and down adjustment device, it realizes automated and intelligent scanning operations. For example, it can automatically adjust the scanning mode according to the loading and unloading rhythm, improve the efficiency of cargo monitoring during the loading and unloading process of bulk cargo terminals, reduce manual intervention and optimize the operation process.

The mounting assembly 1 is fixedly mounted with a left-right adjustment device 4 and a right-down adjustment device 5. The mounting assembly 1 includes an L-shaped mounting plate 101. The right-down adjustment device 5 includes two sets of mounting brackets 501 fixedly mounted on the surface of the L-shaped mounting plate 101. A mounting post 502 is fixedly mounted between the two sets of mounting brackets 501. A second motor 503 is fixedly mounted on the surface of the left mounting bracket 501. A second driving helical gear 505 is fixedly mounted on the second motor 503 via a second rotating shaft 504. 05 The rotating shaft 506 and the driving bevel gear 508 are connected by the second driven helical gear 507. The mounting assembly 1 serves as the basic support, and the L-shaped mounting plate 101 provides a stable mounting surface for the left and right adjustment device 4 and the up and down adjustment device 5. In the up and down adjustment device 5, two sets of mounting brackets 501 and mounting columns 502 form a transmission structure frame. The power output of the second motor 503 is transmitted to the second driving helical gear 505 through the second rotating shaft 504. By meshing with the second driven helical gear 507, it drives the rotating shaft 506 and the driving bevel gear 508 to rotate, providing power for the up and down angle adjustment of the laser scanner 2 and realizing the adjustment of the vertical scanning range.

[0024] The left and right adjustment device 4 includes a first motor 401 fixedly mounted on the surface of the right mounting bracket 501.

The first driven helical gear 405 is fixedly mounted on the bottom of the rotating column 404, and the U-shaped frame 406 is fixedly mounted on the top of the rotating column 404. The rotating rod 407 is rotatably connected to the... Inside the U-shaped frame 406, the driven bevel gear 408 and the connecting block 409 are fixedly installed on the circumferential surface of the rotating rod 407.

The U-shaped frame 406 and the rotating rod 407 form a secondary transmission structure. The driven bevel gear 408 and the connecting block 409 cooperate to transmit the power of the up and down adjustment device 5 to the extension rod 3, allowing the laser scanner 2 to be flexibly adjusted in the horizontal and vertical directions, covering different angles of the bulk cargo terminal loading and unloading area, and improving the scanning accuracy.

A programming logic controller is fixedly installed on one side of the L-shaped mounting plate 101, and the programming logic controller is electrically connected to the laser scanner 2. The L-shaped mounting plate 101 can be quickly positioned with the dock facilities via the fixing ears 102 and the first mounting holes 103. The locking ears 105 and the second mounting holes 106 strengthen the vertical fixation, adapting to complex installation scenarios. The internal reinforcing ribs 104 improve structural strength, resisting vibration and impact during dock operations, and ensuring the stability of the device. The integrated programming logic controller (PLC) is electrically connected to the laser scanner 2, enabling intelligent control of scanning frequency, start / stop, and data transmission. It automatically adapts to the loading and unloading rhythm in conjunction with the adjustment device, optimizing the operation process.

The reinforcing rib 104 ensures structural stability. During operation, the programmable logic controller (PLC) coordinates the control. In the left and right adjustment device 4, the first motor 401 drives the first rotating shaft 402 to rotate, causing the first driving helical gear 403 to drive the meshing first driven helical gear 405 and rotating column 404 to rotate, thereby causing the U-shaped frame 406 and the laser scanner 2 to deflect left and right and adjust up and down. In step 5, the second motor 503 drives the second rotating shaft 504 to rotate, the second driving helical gear 505 drives the meshing second driven helical gear 507 and rotating shaft 506 to rotate, and the driving bevel gear 508 links with the driven bevel gear 408 to make the laser scanner 2 swing up and down. Under multi-dimensional adjustment, the laser scanner 2 covers different angles of the loading and unloading area, accurately captures cargo information, and automatically adjusts the scanning mode according to the loading and unloading rhythm to realize automated and intelligent scanning operations. The gear transmission ensures the long-term stable operation of the device, reduces operation and maintenance costs, and completes efficient monitoring of cargo loading and unloading at the bulk cargo terminal. At this point, the entire process is completed.
