Description

Technical Field

[0001] The present invention relates to the field of control test systems, in particular to a remote fully automatic intelligent control device for a ship unloader. Background Art

[0002] A ship unloader is a device specifically designed to efficiently transfer bulk materials from a ship's hold to a bulk material conveyor belt at the dock. Its primary function is to grab bulk materials from the ship using a grab bucket and unload them into a conical hopper. The material is then transported through the hopper's outlet to a belt conveyor and then to the storage yard. Ship unloaders primarily include bridge-type grab bucket unloaders, which are indispensable in port terminals. Specialized control equipment is required to control the movement of the grab bucket during operation.

[0003] In the prior art, for bridge-type grab ship unloaders, the control equipment of the grab equipment requires manual or automatic control. However, during long-term operation, the grab is frequently subjected to external force impacts, which can easily lead to deformation of its own structure. This partial deformation will cause unstable shaking during the movement process, increasing the risk of collision. On the other hand, the grabbing gap at the bottom of the grab will also be deformed or expanded due to collisions caused by repeated use. Conventional control equipment can only move according to a preset path, and cannot test or accurately monitor the above-mentioned control problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a remote fully automatic intelligent control device for a ship unloader to solve the problems raised in the above background technology. The present invention can accurately monitor and test the movement path of the grab bucket each time the grab bucket is controlled to ensure that it is detected in time when unstable phenomena occur. It can also improve the sensitivity of control. The plug-in mechanism can be used to detect such incomplete closure problems, further increase the monitoring items of the grab bucket control process, and reduce the amount of material spilled during the grab bucket movement control process. In conjunction with the collection component at the end, the collected material can be automatically discharged when a single control test is completed.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a remote fully automatic intelligent control device for a ship unloader, comprising a control device body, the control device body comprising a synchronous moving track 1, a testing mechanism 4, a positioning monitoring module 5 and a collection component 6, one end of the synchronous moving track 1 is screwed with a motor 3, and a slide groove 2 is opened inside the synchronous moving track 1, the top and bottom ends of the slide groove 2 are open, the output end of the motor 3 is inserted with a screw rod 7, the testing mechanism 4 is installed at the top of the synchronous moving track 1, and a plug-in mechanism 8 is installed on the inner side of the testing mechanism 4, the testing mechanism 4 is used to test the grab movement control path of the ship unloader, and the plug-in mechanism 8 is used to test the grab pressure of the ship unloader, the positioning monitoring module 5 is screwed to the side of the controlled grab bucket, and the end of the synchronous moving track 1 is welded with a collection component 6, and the testing mechanism 4 moves to the end along the slide groove 2 and docks with the collection component 6 part, and the end of the screw rod 7 is embedded in the end of the inner wall of the slide groove 2 through a bearing. The synchronous moving track 1 in the fully automatic intelligent control device cooperates with the testing mechanism 4 and the positioning monitoring module 5 to test the movement control process of the grab bucket, thereby improving the accuracy and reliability of the movement control.

[0029] During installation, the positioning monitoring module 5 is directly installed on the side of the controlled grab bucket, while the synchronous movement and its surface structural parts are installed at the bottom of the path where the grab bucket can move. After the grab bucket is controlled by the control system to grab the material, the grab bucket is controlled to move over the top of the test mechanism 4 and is controlled to be in an area above the test mechanism 4. The motor 3 is synchronously controlled to operate, and the movement of the test mechanism 4 is used to achieve the purpose of testing the grab bucket's movement path. At the same time, the grab bucket is also periodically controlled to move downward until the bottom of the grab bucket is docked with the plug-in mechanism 8. The plug-in mechanism 8 is used to test the gripping pressure at the bottom of the grab bucket to ensure that the material inside can maintain a stable grip during the subsequent grab bucket movement control process. The pressure sensor 21 and laser ranging module 30 used in this application are both existing mature technologies and are not within the scope of protection of the present invention. Therefore, their internal structure, working principle, specifications and parameters and other technical contents will not be described in detail here.

[0030] In this embodiment, the test mechanism 4 includes a panel 9, a reversing groove 10, and a threaded sleeve 11. The bottom of the panel 9 is integrally formed with the reversing groove 10, and the bottom of the reversing groove 10 is provided with a threaded sleeve 11. A reversing plate 13 is installed inside the reversing groove 10, and an inclined plate 15 is integrally formed at the end of the reversing plate 13. The top of the test mechanism 4 and the end facing the collection assembly 6 are both open. The threaded sleeve 11 is embedded in the interior of the chute 2 and is sleeved on the surface of the screw 7. A rotating shaft 12 is inserted into one end of the reversing plate 13. The two ends of the rotating shaft 12 are embedded in the inner wall of the reversing groove 10, and the side edges of the reversing plate 13 are in contact with the inner wall of the reversing groove 10. Specifically, after starting the motor 3, the motor 3 drives the screw rod 7 to rotate, and the screw rod 7 cooperates with the threaded sleeve 11 to directly slide the entire test mechanism 4 along the inside of the slide 2, and controls the test mechanism 4 and the controlled grab to move synchronously. The laser ranging module 30 can be used to realize the accuracy test process of the grab movement path. At the same time, the test mechanism 4 can also be moved to the end and docked with the collection component 6 to collect the material residue dropped by the test mechanism 4 during the test process.

[0031] In this embodiment, the plug-in mechanism 8 comprises a plug-in rod 16, a base 19, and a lifting column 35. A notch 14 is defined in the surface of the flip plate 13, through which the plug-in rod 16 extends upward. A limit stop 17 is integrally formed at the bottom of the plug-in rod 16, and a lifting column 35 is mounted at the bottom of the limit stop 17. A spring 18 is sleeved on the lifting column 35. A base 19 is welded to the bottom end of the flip trough 10. A strip-shaped hole 20 is defined at the top end of the base 19, through which the lifting column 35 passes. A pressure sensor 21 is also screwed onto the bottom of the flip trough 10. The pressure sensor 21 is mounted inside the base 19. The ends of the spring 18 are welded to the surfaces of the limit stop 17 and the base 19, respectively. The plug-in rod 16 is positioned in the middle of the flip plate 13, and the top end of the limit stop 17, supported by the spring 18, is in contact with the bottom surface of the flip plate 13. By docking the grab bucket part with the test mechanism 4 under regular control, and cooperating with the plug-in mechanism 8 to plug into the gap position at the bottom of the grab bucket, when the gap at the bottom of the grab bucket is deformed due to long-term use and collision, or when the power structure controlling its closure produces faults such as insufficient pressure, the plug-in mechanism 8 can be used to detect such incomplete closure problems, further increasing the monitoring items of the grab bucket control process and reducing the amount of material spilled during the grab bucket movement control process.

[0032] Specifically, after the controlled grab bucket part moves to the inner side of the enclosure 9, it directly drives the entire grab bucket to move downward, and finally sets the bottom gap position of the grab bucket on the top of the plug-in rod 16. At this time, if the grabbing and clamping force of the bottom of the grab bucket is insufficient, the plug-in rod 16 will be inserted, causing the plug-in rod 16 to be directly embedded in the interior of the grab bucket. At this time, the entire plug-in mechanism 8 cannot be controlled to move downward. If the grabbing force of the entire grab bucket meets the requirement, the bottom of the grab bucket will press on the top of the plug-in rod 16 to control the plug-in rod 16 to move downward, thereby causing the spring 18 to compress, and the bottom of the lifting column 35 to press against the bottom pressure sensor 21. With the help of the signal change feedback from the pressure sensor 21, it can be judged that the current grab bucket's grabbing pressure meets the requirement.

[0033] In this embodiment, the positioning monitoring module 5 includes a mounting frame 27, which is generally rectangular in structure. A top extension plate 29 is integrally formed on the side of the mounting frame 27, and a laser ranging module 30 is screwed to the bottom of the top extension plate 29. A bottom extension plate 31 is integrally formed on the side of the enclosure 9. A mounting plate 28 is also integrally formed on the side of the mounting frame 27. The positioning monitoring module 5 is bolted through the mounting plate 28 and secured to the side of the controlled grab bucket. A first reflective sheet 32 is attached to the surface of the bottom extension plate 31. A protrusion 33 is inserted in the middle of the first reflective sheet 32, and a second reflective sheet 34 is attached to the top of the protrusion 33. A track structure controls the movement of the surface testing mechanism 4. The positioning monitoring module 5 is then mounted on the side of the ship unloader grab bucket. This allows for precise monitoring and testing of the grab bucket's movement during each controlled movement, ensuring timely detection of any instabilities and improving control sensitivity.

[0034] Specifically, since the positioning monitoring module 5 is installed on the side of the controlled grab, when the controlled grab moves to the top of the test mechanism 4, it will directly irradiate toward the bottom with the help of the laser ranging module 30 on the side. Therefore, after the laser ranging module 30 irradiates the second reflective sheet 34, the position of the grab can be accurately located. Subsequently, by starting the motor 3, the test mechanism 4 is controlled to move synchronously with the grab to achieve accurate positioning of the grab's moving position, and when the grab's moving speed deviates, the laser ranging module 30 irradiates the first reflective sheet 32 and then irradiates the second reflective sheet 34. The distance signal collected by the laser ranging module 30 can be used to provide information feedback on the moving position of the controlled grab.

[0035] In this embodiment, the collection assembly 6 includes a collection bin 22, a top support plate 23, and a fixed plate 24. The top support plate 23 is integrally formed at the front end of the bottom of the collection bin 22. A bottom plate 25 is provided at the bottom of the collection bin 22, and the front end of the bottom plate 25 is welded to the fixed plate 24. The bottom of the rear end of the bottom plate 25 is connected to a discharge channel 26. The side of the bottom plate 25 close to the discharge channel 26 is tilted downward, and the bottom of the fixed plate 24 is welded to the surface of the synchronous moving track 1. Since the test mechanism 4 is driven to move synchronously with the grab bucket portion that moves over the top by the synchronous moving track 1, it is possible to collect materials spilled during the mobile test. In conjunction with the collection assembly 6 at the end, the collected materials can be automatically discharged when a single control test is completed.

[0036] Specifically, the motor 3 drives the screw rod 7 to rotate, and the screw rod 7 cooperates with the threaded sleeve 11 to drive the entire test mechanism 4 to move along the slide 2, and finally the test mechanism 4 will be pressed against the collection component 6 at the end. By contacting the top plate 23 on the collection component 6 with the inclined plate 15, the entire inclined plate 15 can be pressed and guided so that the flip plate 13 is flipped downward at a small angle, so that the small amount of debris carried on the flip plate 13 enters the collection component 6 along the tilted flip plate 13 and the inclined plate 15, and is finally discharged along the discharge channel 26 at the end.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
