Description

Technical Field

[0001] This invention relates to the field of control and testing systems, specifically to a remote fully automatic intelligent control device for a ship unloader. Background Technology

[0002] A ship unloader is a specialized device used to efficiently transfer bulk materials from ship holds to bulk conveyor belts on the dock. Its main function is to grab bulk materials from the ship using a grab bucket, unload them into a conical hopper, and finally send them through the hopper's outlet to a belt conveyor for transport to the stockyard. Ship unloaders mainly include bridge-type grab unloaders, which are indispensable in port terminals. During operation, specialized control equipment is required to operate the movement of the grab bucket.

[0003] In existing technologies for bridge-type grab unloaders, the control equipment for the grab bucket requires manual or automated operation. However, during long-term operation, the grab bucket is frequently subjected to external impacts, which can easily lead to structural deformation. This deformation can cause unstable swaying during movement, increasing the risk of collisions. On the other hand, the grab gap at the bottom of the grab bucket can also deform or widen due to repeated collisions. Conventional control equipment can only move according to a preset path and cannot test or accurately monitor and handle the above-mentioned control problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a remote, fully automatic, intelligent control device for ship unloaders, thereby solving the problems mentioned in the background section. This invention can precisely monitor and test the movement path of the grab bucket each time it is moved, ensuring timely detection of any instability and improving control sensitivity. The plug-in mechanism can detect incomplete closure issues, further increasing the monitoring items for the grab bucket control process and reducing material spillage during grab bucket movement control. Combined with the end-of-line collection component, the collected material can be automatically discharged upon completion of a single control test.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a remote fully automatic intelligent control device for a ship unloader, comprising a control device body, the control device body including a synchronous moving track, a testing mechanism, a positioning monitoring module, and a collection component. A motor is screwed to one end of the synchronous moving track, and a groove is formed inside the synchronous moving track, with the top and bottom of the groove open. A lead screw is inserted into the output end of the motor. The testing mechanism is installed at the top of the synchronous moving track, and a connecting mechanism is installed inside the testing mechanism. The testing mechanism is used to test the movement control path of the ship unloader's grab bucket, and the connecting mechanism is used to test the grabbing pressure of the ship unloader's grab bucket. The positioning monitoring module is screwed to the side of the controlled grab bucket. A collection component is welded to the end of the synchronous moving track. After the testing mechanism moves along the groove to the end, it docks and fits with the collection component. The end of the lead screw is embedded into the inner wall of the groove via a bearing.

[0006] Furthermore, the testing mechanism includes a surrounding plate, a flipping groove, and a threaded sleeve. The bottom of the surrounding plate is integrally formed with a flipping groove, the bottom of the flipping groove is provided with a threaded sleeve, a flipping plate is installed inside the flipping groove, and an inclined plate is integrally formed at the end of the flipping plate.

[0007] Furthermore, the top of the testing mechanism and the end facing the collection component are both in an open state. The threaded sleeve is embedded inside the groove and is sleeved on the surface of the lead screw. One end of the flip plate is fitted with a rotating shaft, and both ends of the rotating shaft are embedded in the inner wall of the flip groove. The side of the flip plate is in contact with the inner wall of the flip groove.

[0008] Furthermore, the insertion mechanism includes an insertion rod, a base, and a lifting column. The surface of the flip plate has a notch, and the insertion rod extends upward from the inside of the notch. The bottom of the insertion rod is integrally formed with a limit baffle, and the bottom of the limit baffle is fitted with a lifting column.

[0009] Furthermore, a spring is fitted on the surface of the lifting column, a base is welded to the bottom of the tilting groove, a strip-shaped hole is opened at the top of the base, the lifting column passes through the inside of the strip-shaped hole, and a pressure sensor is screwed to the bottom of the tilting groove.

[0010] Furthermore, the pressure sensor is installed in the inner area of ​​the base, the two ends of the spring are respectively welded to the surface of the limiting baffle and the base, the plug rod is located in the middle of the flip plate, and the top of the limiting baffle is supported by the spring and fits against the bottom surface of the flip plate.

[0011] Furthermore, the positioning and monitoring module includes a mounting frame, which is rectangular in shape. A top extension plate is integrally formed on the side of the mounting frame, and a laser ranging module is screwed to the bottom of the top extension plate. A bottom extension plate is integrally formed on the side of the enclosure, and a mounting plate is also integrally formed on the side of the mounting frame.

[0012] Furthermore, the positioning and monitoring module is fixed to the side of the controlled grab bucket by bolts passing through the mounting plate. A first reflective sheet is attached to the surface of the bottom extension plate, a protruding post is inserted in the middle of the first reflective sheet, and a second reflective sheet is attached to the top of the protruding post.

[0013] Furthermore, the collection component includes a collection chamber, a top support plate, and a fixing plate. The bottom front end of the collection chamber is integrally formed with a top support plate, the bottom of the collection chamber is provided with a bottom plate, and the front end of the bottom plate is welded with a fixing plate.

[0014] Furthermore, the bottom rear end of the base plate is connected to a discharge channel, the side of the base plate near the discharge channel is inclined downwards, and the bottom of the fixing plate is welded to the surface of the synchronous moving track.

[0015] The beneficial effects of this invention are:

[0016] 1. The remote fully automatic intelligent control equipment for the ship unloader uses a track structure to control the movement of the testing mechanism on the surface. The positioning and monitoring module is mounted on the side of the grab bucket of the ship unloader. This allows for precise monitoring and testing of the grab bucket's movement path each time it is controlled to move, ensuring that any instability is detected in a timely manner and improving the sensitivity of the control.

[0017] 2. The remote fully automatic intelligent control equipment of this ship unloader docks with the testing mechanism through the periodically controlled grab bucket section. It works in conjunction with the insertion mechanism to connect with 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 experiences insufficient pressure, the insertion mechanism can be used to detect such incomplete closure problems. This further increases the monitoring items of the grab bucket control process and reduces the amount of material spillage during the grab bucket movement control process.

[0018] 3. The remote fully automatic intelligent control equipment of this ship unloader drives the test mechanism and the top grab bucket to move synchronously through the synchronous moving track. Therefore, it can collect the materials spilled during the moving test. With the collection component at the end, the collected materials can be automatically discharged when a single control test is completed. Attached Figure Description

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1 to 7The present invention provides the following technical solution: a remote fully automatic intelligent control device for a ship unloader, comprising a control device body, the control device body including a synchronous moving track 1, a testing mechanism 4, a positioning monitoring module 5, and a collection component 6. A motor 3 is screwed to one end of the synchronous moving track 1, and a groove 2 is provided inside the synchronous moving track 1. The top and bottom ends of the groove 2 are open. A lead screw 7 is inserted into the output end of the motor 3. The testing mechanism 4 is installed at the top of the synchronous moving track 1, and a connecting mechanism 8 is installed on the inner side of the testing mechanism 4. The testing mechanism 4 is used to test the movement control path of the grab bucket of the ship unloader. The connecting mechanism 8 is used to test the grab pressure of the grab bucket of the ship unloader. The positioning monitoring module 5 is screwed to the side of the controlled grab bucket. A collection component 6 is welded to the end of the synchronous moving track 1. After the testing mechanism 4 moves along the groove 2 to the end, it partially docks and fits with the collection component 6. The end of the lead screw 7 is embedded into the inner wall of the groove 2 through a bearing. The fully automatic intelligent control equipment is equipped with a synchronous moving track 1, which, together with the testing mechanism 4 and the positioning monitoring module 5, tests the movement control process of the grab bucket, thereby improving the accuracy and reliability of movement control.

[0029] During installation, the positioning monitoring module 5 is directly installed on the side of the controlled grab bucket. The synchronous movement and its surface structure are installed at the bottom of the grab bucket's movement path. After the grab bucket grabs the material, the control system moves the grab bucket over the top of the testing mechanism 4 and positions it closer to the upper part of the testing mechanism 4. Simultaneously, the motor 3 is controlled to operate. The movement of the testing mechanism 4 tests the grab bucket's movement path. The grab bucket is also periodically lowered until its bottom aligns with the insertion mechanism 8. The insertion mechanism 8 then tests the gripping pressure at the bottom of the grab bucket, ensuring stable material gripping during subsequent grab bucket movement control. Furthermore, the pressure sensor 21 and laser ranging module 30 used in this application are existing mature technologies and are not within the scope of this invention. Therefore, their internal structure, working principle, and specifications are not described in detail here.

[0030] In this embodiment, the testing mechanism 4 includes a surrounding plate 9, a tilting groove 10, and a threaded sleeve 11. The bottom of the surrounding plate 9 is integrally formed with the tilting groove 10, and the bottom of the tilting groove 10 is provided with the threaded sleeve 11. A tilting plate 13 is installed inside the tilting groove 10, and an inclined plate 15 is integrally formed at the end of the tilting plate 13. The top of the testing mechanism 4 and the end facing the collecting assembly 6 are both open. The threaded sleeve 11 is embedded in the interior of the sliding groove 2 and is sleeved on the surface of the lead screw 7. A rotating shaft 12 is inserted into one end of the tilting plate 13, and both ends of the rotating shaft 12 are embedded in the inner wall of the tilting groove 10. The side of the tilting plate 13 is in contact with the inner wall of the tilting groove 10. Specifically, after starting the motor 3, the motor 3 drives the lead screw 7 to rotate. The lead screw 7, in conjunction with the threaded sleeve 11, can directly slide the entire testing mechanism 4 along the inside of the slide groove 2, controlling the testing mechanism 4 to move synchronously with the controlled grab bucket. The laser ranging module 30 can then accurately test the movement path of the grab bucket. At the same time, the testing mechanism 4 can be moved to the end and docked with the collection component 6 to collect the material residue that falls off the testing mechanism 4 during the testing process.

[0031] In this embodiment, the insertion mechanism 8 includes an insertion rod 16, a base 19, and a lifting column 35. A notch 14 is formed on the surface of the flip plate 13, through which the insertion rod 16 extends upwards. A limit baffle 17 is integrally formed at the bottom of the insertion rod 16, and the lifting column 35 is inserted into the bottom of the limit baffle 17. A spring 18 is fitted onto the surface of the lifting column 35. The base 19 is welded to the bottom end of the flip groove 10, and a strip-shaped hole 20 is formed at the top end of the base 19. The lifting column 35 passes through the strip-shaped hole 20. A pressure sensor 21 is screwed to the bottom of the flip groove 10. The pressure sensor 21 is installed in the inner area of ​​the base 19. The two ends of the spring 18 are welded to the surfaces of the limit baffle 17 and the base 19, respectively. The insertion rod 16 is located in the middle of the flip plate 13, and the top end of the limit baffle 17, supported by the spring 18, is in contact with the bottom surface of the flip plate 13. The grab bucket is periodically controlled and docked with the testing mechanism 4. The insertion mechanism 8 is used to connect with the gap 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 experiences insufficient pressure, the insertion mechanism 8 can be used to detect such incomplete closure. This further increases the monitoring items of the grab bucket control process and reduces the amount of material spillage during the grab bucket movement control process.

[0032] Specifically, after the controlled grab bucket moves to the inside of the enclosure 9, it directly drives the entire grab bucket to move downwards, eventually positioning the bottom gap of the grab bucket over the top of the connector rod 16. If the gripping force at the bottom of the grab bucket is insufficient, the connector rod 16 will be inserted directly into the inside of the grab bucket, making it impossible to control the entire connector mechanism 8 to move downwards. If the gripping force of the entire grab bucket meets the requirements, the bottom of the grab bucket will press against the top of the connector rod 16, controlling the connector rod 16 to move downwards, which in turn compresses the spring 18. The bottom of the lifting column 35 then abuts against the bottom pressure sensor 21. By using the signal change fed back by the pressure sensor 21, it can be determined that the current gripping pressure of the grab bucket meets the requirements.

[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 plate 9, and a mounting plate 28 is also integrally formed on the side of the mounting frame 27. The positioning monitoring module 5 is fixed to the side of the controlled grab bucket using bolts passing through the mounting plate 28. A first reflective sheet 32 ​​is attached to the surface of the bottom extension plate 31, a protruding post 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 protruding post 33. Through a track structure, the movement of the surface testing mechanism 4 is controlled, and the positioning monitoring module 5 is mounted on the side of the unloader grab bucket. This allows for precise monitoring and testing of the grab bucket's movement path each time it is moved, ensuring timely detection of any instability and improving control sensitivity.

[0034] Specifically, since the positioning monitoring module 5 is installed on the side of the controlled grab bucket, when the grab bucket moves to the top of the test mechanism 4, it will directly use the side laser ranging module 30 to shine light on the bottom. Therefore, after the laser ranging module 30 shines on the second reflector 34, the position of the grab bucket can be accurately located. Subsequently, by starting the motor 3, the test mechanism 4 is controlled to move synchronously with the grab bucket to achieve accurate positioning of the grab bucket's movement position. When there is a deviation in the grab bucket's movement speed, the laser ranging module 30 will switch from shining on the first reflector 32 to shining on the second reflector 34. The distance signal collected by the laser ranging module 30 can then be used to provide feedback on the controlled movement position of the grab bucket.

[0035] In this embodiment, the collection component 6 includes a collection bin 22, a top support plate 23, and a fixing plate 24. The top support plate 23 is integrally formed at the bottom front end of the collection bin 22, and a bottom plate 25 is provided at the bottom of the collection bin 22. The fixing plate 24 is welded to the front end of the bottom plate 25. A discharge channel 26 is connected to the rear bottom of the bottom of the bottom plate 25, and the side of the bottom plate 25 near the discharge channel 26 is inclined downwards. The bottom of the fixing plate 24 is welded to the surface of the synchronous moving track 1. Since the test mechanism 4 moves synchronously with the grab bucket part that moves past the top via the synchronous moving track 1, the material spilled during the moving test can be collected. With the end collection component 6, the collected material can be automatically discharged when a single control test is completed.

[0036] Specifically, the motor 3 drives the lead screw 7 to rotate, and the lead screw 7, in conjunction with the threaded sleeve 11, drives the entire testing mechanism 4 to move along the slide 2. Eventually, the testing mechanism 4 will be pushed against the collection component 6 at the end. The top plate 23 on the collection component 6 contacts the inclined plate 15, which can push the entire inclined plate 15 towards the pressing guide, thereby causing the flip plate 13 to flip downward at a small angle. This allows the small amount of debris collected on the flip plate 13 to enter the collection component 6 along the tilted flip plate 13 and the inclined plate 15, and finally be discharged along the discharge channel 26 at the end.

[0037] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent 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.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
