Description

Technical Field

[0001] This utility model relates to the field of steel plate surface grinding technology, and in particular to a device for grinding the surface of ship steel plates. Background Technology

[0002] Grinding the surface of ship steel plates is primarily to thoroughly remove scale, rust, old coatings, and contaminants, ensuring that subsequent anti-corrosion coatings adhere firmly. This is the most critical step in ship corrosion prevention. Simultaneously, grinding eliminates minor unevenness and welding spatter on the steel plate surface, reduces stress concentration, helps improve structural safety and fatigue life, and provides a clean and qualified surface for subsequent painting, inspection, and other processes.

[0003] Existing equipment lacks a flexible and stable support structure, making it difficult to adjust the position and height of the support points according to the different sizes, placement angles, and specific location requirements of the ship's steel plates. During grinding, the equipment is prone to swaying or shifting due to support imbalance, causing the grinding trajectory to deviate from the preset path. This fails to guarantee the flatness and uniformity of the steel plate surface, thus affecting the adhesion of subsequent anti-corrosion coatings and the structural safety of the ship. Furthermore, ship steel plate grinding operations generate a large amount of metal debris and dust. Existing equipment lacks external shielding structures, allowing these impurities to directly adhere to the surface of the equipment's support adjustment components (such as threaded rods, threaded sleeves, and connecting nodes), and even seep into the gaps between components. Long-term accumulation can cause component corrosion and jamming, damage the thread fit accuracy, lead to support height adjustment failure, and lateral position movement jamming, shorten the equipment's service life, and increase maintenance costs and frequency. Therefore, a ship steel plate surface grinding device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a grinding device for the surface of ship steel plates, which aims to improve the problems of easy shaking and displacement during grinding that affect grinding accuracy and lack of protection that makes it susceptible to corrosion by grinding debris and dust in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grinding device for the surface of ship steel plates, comprising a grinding device body, a support mechanism provided on the outer wall of the grinding device body, the support mechanism comprising an outer frame, the outer frame being fixedly connected to the outer wall of the grinding device body, and a protective mechanism provided on the outer wall of the outer frame; The support mechanism further includes a first threaded rod, which is rotatably connected to the inner wall of the outer frame. A connecting rod is threadedly connected to the outer wall of the first threaded rod, and a threaded sleeve is fixedly connected to the outer wall of the connecting rod. A second threaded rod is threadedly connected to the inner wall of the threaded sleeve, and a support block is rotatably connected to the outer wall of the bottom end of the second threaded rod.

[0006] As a further description of the above technical solution: the protective mechanism includes a protective plate, which is detachably connected to the outer wall of the outer frame. A connecting plate is slidably connected to the inner wall of the protective plate, and a fixing buckle is slidably connected to the inner wall of the protective plate. The fixing buckle is elastically connected to the inner wall of the protective plate by a tension spring, and a fixing block is fixedly connected to the outer wall of the outer frame.

[0007] As a further description of the above technical solution: the threaded sleeve is provided in two sets, and the two sets of threaded sleeves are mirror-distributed on the inner wall of the outer frame. The inner wall of the outer frame is provided with a guide groove, and the threaded sleeve is slidably connected in the guide groove.

[0008] As a further description of the above technical solution: one end of the tension spring is fixedly connected to the inner wall of the fixing buckle, and the other end of the tension spring is fixedly connected to the inner wall of the protective plate.

[0009] As a further description of the above technical solution: the protective plate is provided in two sets, and the two sets of protective plates are slidably connected to the outer walls of both ends of the connecting plate.

[0010] As a further description of the above technical solution: the outer wall of the protective plate is provided with a fixing groove, and the fixing block is inserted into the fixing groove.

[0011] As a further description of the above technical solution: four sets of fixing blocks are provided, and two sets of fixing blocks are fixedly connected to the outer wall of the support block.

[0012] As a further description of the above technical solution: the inner wall of the fixing block is provided with a fixing slot, and the fixing buckle is engaged in the fixing slot.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the outer frame first provides the installation foundation for the whole. Rotating the first threaded rod causes the connecting rod threaded to its outer wall to move the threaded sleeve laterally along the guide groove on the inner wall of the outer frame, adjusting the position of the threaded sleeve to suit the grinding requirements. Then, rotating the second threaded rod causes the support block to move up and down during rotation, adjusting the support height. Finally, the support block contacts the support surface, providing stable support for the grinding device body and ensuring smooth grinding operations. This improves the problem of easy shaking and displacement during grinding in the prior art, which affects grinding accuracy.

[0014] 2. In this utility model, the protective plate is first aligned with the fixing block on the outer wall of the outer frame, so that the fixing block is inserted into the fixing groove of the protective plate. At this time, the fixing buckle on the inner wall of the protective plate is engaged in the fixing groove of the fixing block under the elastic tension of the tension spring, thereby fixing the protective plate to the outer frame. If the spacing changes after the second threaded rod is adjusted, the protective plate can slide along the connecting plate to adjust the spacing between the two sets of protective plates to fit. The protective plate can shield external parts and reduce the corrosion of grinding debris and dust. When disassembling, simply pull the fixing buckle away from the fixing groove to remove the protective plate, thereby improving the problem of lack of protection and susceptibility to corrosion of grinding debris and dust in the prior art.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1As shown, one embodiment of this utility model provides a grinding device for the surface of ship steel plates, including a grinding device body 1. A support mechanism 2 is provided on the outer wall of the grinding device body 1. The support mechanism 2 provides stable support for the grinding device body 1 and can adjust the support position and height to avoid shaking and displacement during grinding. The support mechanism 2 includes an outer frame 21, which connects the grinding device body 1 with the support and protective structure to form a device frame, ensuring the stability of the position of each component. The outer frame 21 is fixedly connected to the outer wall of the grinding device body 1. A protective mechanism 3 is provided on the outer wall of the outer frame 21. The protective mechanism 3 shields the debris and dust generated during grinding, protects the components of the support mechanism 2, reduces corrosion, and extends the life of the device.

[0019] Reference Figure 2 As shown, the support mechanism 2 also includes a first threaded rod 25. When the first threaded rod 25 rotates, it drives the connecting rod 26 to move, adjusting the lateral position of the threaded sleeve 23 to adapt to different grinding requirements. The first threaded rod 25 is rotatably connected to the inner wall of the outer frame 21. The outer wall of the first threaded rod 25 is threadedly connected to the connecting rod 26. The connecting rod 26 is fixedly connected to the threaded sleeve 23 and the first threaded rod 25, transmitting the rotational power of the first threaded rod 25 and driving the threaded sleeve 23 to move. The outer wall of the connecting rod 26 is fixedly connected to the threaded sleeve 23. The threaded sleeve 23 connects the first threaded rod 25 and the second threaded rod 22, transmitting power and assisting in adjusting the support position and height. The inner wall of the threaded sleeve 23 is threadedly connected to the second threaded rod 22. The second threaded rod 22 cooperates with the threaded sleeve 23 to rotate and adjust the height of the support block 24, thereby adjusting the support height at one end of the device. The bottom outer wall of the second threaded rod 22 is rotatably connected to the support block 24. The support block 24 contacts the support surface, supporting the device and enhancing the stability of the device during grinding operations.

[0020] Reference Figures 3-4 As shown, the protective mechanism 3 includes a protective plate 34. The protective plate 34 shields the external components of the grinding device, reducing damage to internal components and personnel from grinding debris and dust, thus providing protection. The protective plate 34 is detachably connected to the outer wall of the outer frame 21. A connecting plate 35 is slidably connected to the inner wall of the protective plate 34, connecting two sets of protective plates 34. The distance between the two sets of protective plates 34 can be adjusted to match the distance adjusted by the second threaded rod 22. A fixing buckle 33 is slidably connected to the inner wall of the protective plate 34. Under the action of the tension spring 37, the 33 is inserted into the fixing slot 32, realizing the detachable fixing of the protective plate 34 and the fixing block 31. The fixing buckle 33 is elastically connected to the inner wall of the protective plate 34 through the tension spring 37. The tension spring 37 provides elastic tension to the fixing buckle 33, so that the fixing buckle 33 is stably inserted into the fixing slot 32 and maintains the fixed state. The outer wall of the outer frame 21 is fixedly connected to the fixing block 31. The fixing block 31 cooperates with the fixing slot 36 and the fixing buckle 33 of the protective plate 34 to realize the fixing of the protective plate 34 and the outer frame 21.

[0021] In use, this utility model first provides an installation base for the entire assembly via the outer frame 21. Rotating the first threaded rod 25 causes the connecting rod 26, which is threaded to its outer wall, to move the threaded sleeve 23 laterally along the guide groove 27 on the inner wall of the outer frame 21, adjusting the position of the threaded sleeve 23 to suit the grinding requirements. Next, rotating the second threaded rod 22, which is threaded to the threaded sleeve 23 and has a rotating support block 24 at its bottom, causes the support block 24 to move up and down during rotation, adjusting the support height. Finally, the support block 24 contacts the support surface, providing stable support for the grinding device body 1 and ensuring smooth grinding operations.

[0022] When the protective mechanism 3 is working, first align the protective plate 34 with the fixing block 31 on the outer wall of the outer frame 21, so that the fixing block 31 is inserted into the fixing groove 36 of the protective plate 34. At this time, the fixing buckle 33 on the inner wall of the protective plate 34 is engaged in the fixing groove 32 of the fixing block 31 under the elastic tension of the tension spring 37, thereby fixing the protective plate 34 to the outer frame 21. If the spacing changes after the second threaded rod 22 is adjusted, the protective plate 34 can slide along the connecting plate 35 to adjust the spacing between the two sets of protective plates 34 to fit. The protective plate 34 can shield external parts and reduce the corrosion of grinding debris and dust. When disassembling, simply pull the fixing buckle 33 to disengage from the fixing groove 32 of the fixing block 31 to remove the protective plate 34.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
