Description

Technical Field

[0001] The present invention relates to the technical field of ship unloaders, and in particular to a traveling mechanism for ship unloaders. Background Art

[0002] As an important component of port loading and unloading operations, the stability and efficiency of the ship unloader's traveling mechanism are directly related to the overall operational efficiency of the port. The ship unloader's traveling mechanism usually adopts an advanced axle and traveling wheel combination design to ensure the stable operation of the equipment in a complex and changeable working environment. In order to further improve the performance of the traveling wheel, some designs have added automatic oil scraping devices, which can effectively remove the sludge attached to the traveling wheel, reduce manual maintenance costs, and prevent safety hazards caused by sludge accumulation. At the same time, with the continuous integration of cutting-edge technologies such as artificial intelligence and the Internet of Things, the ship unloader's traveling mechanism is developing in a more intelligent and automated direction to achieve more efficient and accurate loading and unloading operations, and promote the continuous upgrading and transformation of port logistics.

[0003] After searching, the Chinese invention patent number CN113581886A discloses a special small and medium-sized ship unloader;

[0004] Compared with the existing technology, the invention patent with Chinese patent number CN113581886A realizes the lightweight and split design of the ship unloader by splitting the bracket one for installing the grab bucket and the bracket two for installing the unloading system, and connecting the bracket one and the bracket two through a connecting rod. While ensuring the stability of the ship unloader, the ship unloader is realized, the structural weight and complexity are greatly reduced, and the ship unloader is suitable for various large, medium and small berths. It is highly practical and wide. Finally, in theory, it can completely replace the gantry crane unloading. A traveling bridge is installed on the large beam, a main trolley is installed on the traveling bridge, a grab bucket is installed under the main trolley, and the main trolley is controlled by an operation control component. The operation control component includes a traveling component and a lifting and closing component. Both the traveling component and the lifting and closing component are connected to the grab bucket.

[0005] However, during the actual use of the above device, the ship unloader drives the traveling wheels of the ship unloader to move along the dedicated track of the ship unloader through the traveling mechanism. During the frequent operation of the traveling mechanism of the ship unloader, some of the lubricating grease used to lubricate the traveling mechanism will flow out and form sludge that is adsorbed on the traveling wheels of the ship unloader. The sludge adsorbed and accumulated on the traveling wheels will affect the workers' maintenance work on the traveling wheels of the ship unloader, and it is not easy to lock the traveling wheels when they need to stop. Therefore, it is necessary to propose a traveling mechanism for the ship unloader. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art that the presence of oil sludge affects the workers' maintenance work on the ship unloader's traveling wheels and makes it difficult to lock the traveling wheels, and to propose a traveling mechanism for the ship unloader.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1-8 As shown, the present invention proposes a traveling mechanism for a ship unloader, comprising a bearing plate 1, a slide rail 2 symmetrically fixedly connected to the upper portion of the bearing plate 1, a traveling wheel 3 slidably provided on the slide rail 2, a rotating shaft 4 fixedly connected between the two traveling wheels 3, a traveling clamping assembly provided on the traveling wheel 3, the traveling clamping assembly comprising a first servo motor 11, a screw rod 12 and a clamping block 15, a supporting block 16 movably connected to the outer side of the traveling wheel 3, a locking mud removal assembly provided on the supporting block 16, the locking mud removal assembly comprising a squeezing disk 21 and a scraping block 23, a limiting block 24 movably connected to the outer side of the traveling wheel 3, a four-wheel balance beam 25 fixedly connected between the two limiting blocks 24;

[0034] The inner side of the traveling wheel 3 is movably connected to a connecting plate 5, the outer side of the rotating shaft 4 is movably connected to the connecting plate 5, the outer side of the connecting plate 5 is fixedly connected to a support plate 6, the side of the support plate 6 away from the bearing plate 1 is fixedly connected to an L-shaped block 7, and the outer side of the L-shaped block 7 is fixedly connected to a connecting pipe 8;

[0035] The end of the connecting tube 8 away from the L-shaped block 7 is fixedly connected to the protective shell 9, the inner side of the protective shell 9 is fixedly connected to the connecting plate 10, the side of the connecting plate 10 away from the bearing plate 1 is fixedly connected to the fixing plate 28, the side of the connecting plate 10 away from the bearing plate 1 is fixedly connected to the first servo motor 11, and the output shaft end of the first servo motor 11 is fixedly connected to the screw rod 12;

[0036] The screw rod 12 and the slide plate 14 are threadedly connected, and the screw rod 12 and the fixed plate 28 are threadedly connected. The fixed plate 28 is fixedly connected to the limit rod 13 on one side close to the slide plate 14.

[0037] The end of the limiting rod 13 away from the fixed plate 28 is movably connected to the slide plate 14. The ends of the slide plate 14 and the fixed plate 28 away from the first servo motor 11 are fixedly connected to the clamping blocks 15. There are two sets of clamping blocks 15.

[0038] The support plate 6 is fixedly connected to the support block 16 on the side away from the bearing plate 1. The support block 16 is fixedly connected to the side away from the support plate 6 with a second servo motor 17. The output shaft end of the second servo motor 17 is fixedly connected to a worm gear 18.

[0039] A turbine 19 is movably connected to one side of the support plate 6 close to the support block 16, and the worm 18 and the turbine 19 are meshed with each other. A first rack 20 and a second rack 22 are slidably provided on one side of the support plate 6 close to the support block 16, and the opposite sides of the first rack 20 and the second rack 22 are meshed with the turbine 19.

[0040] The ends of the first rack 20 and the second rack 22 away from the turbine 19 are fixedly connected to the extrusion discs 21, and there are two sets of extrusion discs 21;

[0041] The side of the support plate 6 away from the slide rail 2 is fixedly connected to the limit block 24. A second through hole 27 is opened inside the four-wheel balance beam 25. There are two groups of four-wheel balance beams 25.

[0042] In this embodiment, when the device is moving, the walking wheel 3 will move in the horizontal direction along the slide rail 2. While the walking wheel 3 is moving, the device can be locked in place at this position by starting the first servo motor 11 and the second servo motor 17. The specific implementation method is that the two walking wheels 3 are fixedly connected to the rotating shaft 4. The function of the rotating shaft 4 is to drive the walking wheel 3 to move when the rotating shaft 4 rotates. The outer side of the rotating shaft 4 is movably connected to the connecting plate 5. The function of the connecting plate 5 is to connect the upper support plate 6. The support plate 6 is used to support the upper L-shaped block 7. The L-shaped block 7 is connected to the anti-lock brake through the connecting pipe 8. The protective shell 9 is used to protect the first servo motor 11 and the clamping block 15 inside the protective shell 9. The connecting plate 10 is fixedly connected to the protective shell 9. The connecting plate 10 is used to support the first servo motor 11. When the first servo motor 11 is started, it will drive the slide 14 to move back and forth in the horizontal direction. The role of the limit rod 13 is to limit the slide 14. When the slide 14 moves in the horizontal direction, it will drive the clamping block 15 to move in the horizontal direction. The two clamping blocks 15 will clamp the outer side of the walking wheel 3, thereby locking the position of the walking wheel 3;

[0043] Start the second servo motor 17, and the second servo motor 17 will drive the worm rod 18 to rotate. Since the worm rod 18 and the turbine 19 are engaged with each other, the rotation of the worm rod 18 will drive the turbine 19 to rotate. Since the turbine 19 is engaged with the first rack 20 and the second rack 22, when the turbine 19 rotates, it will drive the first rack 20 and the second rack 22 to move toward each other in the horizontal direction. When the first rack 20 and the second rack 22 move, the extrusion plate 21 will be driven to move toward the travel wheel 3. Since the size of the extrusion plate 21 is adapted to the first through hole 26, the extrusion plate 21 is tightly attached to the travel wheel 3 through the connecting plate 5, thereby achieving re-locking of the travel wheel 3.

[0044] Example 2

[0045] like Figures 1-8 As shown, based on the first embodiment, a first through hole 26 is opened inside the connecting disk 5, the size of the extrusion disk 21 is adapted to the size of the first through hole 26, and the second rack 22 is fixedly connected to the scraping block 23 on the side away from the second servo motor 17.

[0046] In this embodiment, when the second rack 22 does not move in the horizontal direction, a scraper block 23 is fixedly connected to the outer side of the second rack 22. There is a certain gap between the scraper block 23 and the traveling wheel 3. When the traveling wheel 3 rotates, sludge will be secreted from the outer side of the traveling wheel 3. The accumulation of sludge may affect the normal operation of the equipment and even cause safety hazards. The scraper block 23 will scrape off the sludge while the traveling wheel 3 rotates, thereby ensuring that the ship unloader maintains the best working state.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
