Description

Technical Field

[0001] This utility model relates to the technical field of anti-lifting devices for container trucks, and in particular to an anti-lifting device for container yard cranes. Background Technology

[0002] Anti-lift device for container yard cranes is a safety device specifically installed on the yard crane (container yard crane). Its core function is to prevent the yard crane from accidentally lifting the container truck along with the container during the container lifting process.

[0003] In actual use, when lifting the container, it is impossible to limit and fix the lifting parts and the container as a whole. It does not have the effect of limiting and locking when lifting the container. At the same time, it is more troublesome when the container falls off later, and the container needs to be inspected when it is on top of the truck.

[0004] An existing patent (publication number: CN222063935U) discloses a container crane anti-lifting device, including a ground, a crane body fixedly connected to the upper surface of the ground, a control panel fixedly connected to the front surface of the crane body, a movable guide rail provided on the inner side wall of the crane body, and a motor body provided on the back of the movable guide rail. This utility model, by activating the cylinder body, can drive the abutment plate to rise, thereby stabilizing the retaining ring to limit the connecting sleeve. Subsequently, by activating the cylinder body, the abutment plate moves downward, thereby the cylinder body and the abutment plate can limit the connecting sleeve at the position of the stabilizing retaining ring. The overall limiting effect of the stabilizing retaining ring is good, thus the whole is relatively stable when lifting the container body.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing anti-lifting devices for container yard cranes are susceptible to damage from wind, sun, and rain, leading to frequent equipment malfunctions and affecting the stability and accuracy of the anti-lifting operation. Furthermore, dust easily accumulates on the surface of the monitoring equipment without a corresponding cleaning mechanism, resulting in blurry monitoring images. This makes it difficult for operators to accurately determine the separation status of the container and the truck, increasing the risk of the truck being accidentally lifted. Overall, this reduces work efficiency and safety, failing to meet the needs of efficient and safe port operations.

[0006] Therefore, a device to prevent container trucks from being lifted is proposed for use in container yards. Utility Model Content

[0007] The purpose of this utility model is to provide a truck anti-lifting device for container yard cranes, which can solve the problems of existing truck anti-lifting devices for container yard cranes. These devices are susceptible to damage from wind, sun, and rain, leading to frequent equipment failures and affecting the stability and accuracy of the anti-lifting operation. Furthermore, the monitoring equipment surface easily accumulates dust without a corresponding cleaning mechanism, resulting in blurry monitoring images. This makes it difficult for operators to accurately judge the separation status of the container and the truck, increasing the risk of the truck being accidentally lifted. Overall, this reduces work efficiency and safety, and fails to meet the needs of efficient and safe port operations.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a container truck anti-lifting device for container yard cranes, comprising a lifting structure and a real-time monitoring structure. A movable structure is provided at the bottom of the lifting structure, and a displacement transmission structure is bolted to the top of the movable structure. A slider is slidably connected to the surface of the displacement transmission structure. The top of the slider is bolted to the bottom of the real-time monitoring structure. A supplementary light is provided at the top of the slider. A protective plate is provided at the top of the real-time monitoring structure, and a protective mechanism is bolted to the bottom of the protective plate. A cleaning mechanism is provided at the bottom of the protective plate, and the side of the cleaning mechanism closest to the protective mechanism contacts the protective mechanism.

[0009] The protective mechanism includes a protective frame, a transparent plate, and an inclined plate. The inclined plate is bolted to the protective frame on the side closest to it. The top of the protective frame is bolted to the bottom of the protective plate. The surface of the transparent plate is fixedly connected to the inner wall of the protective frame. The cleaning mechanism is in contact with the transparent plate on the side closest to it.

[0010] Preferably, the inner wall of the protective plate is provided with a threaded rod, and the surface of the threaded rod is threadedly connected with a movable block.

[0011] Preferably, a fixing frame is bolted to the bottom of the movable block, and the surface of the cleaning mechanism is engaged with the inner wall of the fixing frame.

[0012] Preferably, the cleaning mechanism includes a scraper, a mounting plate, and an insert block. The insert block is bolted to the mounting plate on the side closest to the mounting plate, the scraper block is bolted to the mounting plate on the side closest to the mounting plate, the surface of the insert block is inserted into the inner wall of the fixing frame, and the scraper block is in contact with the transparent plate on the side closest to the transparent plate.

[0013] Preferably, a knob is movably connected to the inner wall of the fixing frame, and the surface of the knob is threadedly connected to the inner wall of the insert block.

[0014] Preferably, the inner wall of the fixing frame has a through hole for use with the knob, and the inner wall of the fixing frame has a slot for use with the insert block.

[0015] Preferably, the inner wall of the protective plate is bolted with a mounting block, and the threaded rod is rotatably connected to the mounting block.

[0016] Preferably, an output component is bolted to the rear side of the mounting block, and the output end of the output component is bolted to the front side of the threaded rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application provides a stable support frame for the overall protection by setting up a protective mechanism in which the protective frame and the protective plate are bolted together. The inclined plate can effectively guide rainwater and other liquids to slide down quickly, avoiding their accumulation on the protective frame and reducing the risk of corrosion to the protective mechanism and the internal real-time monitoring structure. The transparent plate not only ensures the visibility of the real-time monitoring structure, but also blocks external debris and wind and rain, enabling it to operate stably in the harsh outdoor port environment and ensuring that the anti-lifting operation of the container truck is not affected by natural factors.

[0019] 2. This application incorporates a cleaning mechanism that fits tightly against the transparent panel. When the surface of the transparent panel becomes dirty, it can continuously and effectively remove dust and other contaminants adhering to the surface. This prevents dust accumulation from affecting the visibility of the real-time monitoring structure, ensuring that the acquired image information is always clear and accurate. This provides a basis for judging the status of trucks and containers. In conjunction with the protective mechanism, it reduces the risk of trucks being lifted due to unclear visibility.

[0028] 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.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] A container truck anti-lifting device for container yard cranes includes a lifting structure 1 and a real-time monitoring structure 4. A movable structure 5 is provided at the bottom of the lifting structure 1. A displacement transmission structure 6 is bolted to the top of the movable structure 5. A slider 7 is slidably connected to the surface of the displacement transmission structure 6. The top of the slider 7 is bolted to the bottom of the real-time monitoring structure 4. A supplementary light 8 is provided at the top of the slider 7. A protective plate 9 is provided at the top of the real-time monitoring structure 4. A protective mechanism 2 is bolted to the bottom of the protective plate 9. A cleaning mechanism 3 is provided at the bottom of the protective plate 9. The side of the cleaning mechanism 3 closest to the protective mechanism 2 is in contact with the protective mechanism 2.

[0031] The protective mechanism 2 includes a protective frame 201, a transparent plate 202, and an inclined plate 203. The side of the inclined plate 203 near the protective frame 201 is bolted to the protective frame 201. The top of the protective frame 201 is bolted to the bottom of the protective plate 9. The surface of the transparent plate 202 is fixedly connected to the inner wall of the protective frame 201. The side of the cleaning mechanism 3 near the transparent plate 202 is in contact with the transparent plate 202.

[0032] In this embodiment: by setting up a protective mechanism 2, the protective frame 201 in the protective mechanism 2 is bolted to the protective plate 9, providing a stable support frame for the overall protection. The bolted connection between the inclined plate 203 and the protective frame 201 can effectively guide rainwater and other liquids to slide down quickly, preventing them from accumulating on the protective frame 201 and reducing the risk of corrosion to the protective mechanism 2 and the internal real-time monitoring structure 4. The transparent plate 202 is fixed to the inner wall of the protective frame 201, which not only ensures that the field of vision of the real-time monitoring structure 4 is unobstructed and the status of the truck and container can be clearly observed, but also blocks external debris, dust and wind and rain from directly contacting the real-time monitoring structure 4, so that it can still operate stably in the harsh outdoor port environment. The accuracy and continuity of the anti-lifting operation of the container truck are not affected by external natural factors. By setting up a cleaning mechanism 3, which is closely attached to the transparent plate 202, when dirt appears on the surface of the transparent plate 202, it can continuously and effectively remove dust and other contaminants attached to the surface of the transparent plate 202. This can prevent dust accumulation from affecting the visibility of the real-time monitoring structure 4, ensuring that the image information it acquires is always clear and accurate, and providing a reliable basis for judging the separation status of the container truck and the container. In cooperation with the protection mechanism 2, the cleaning mechanism 3 further ensures the stable operation of the real-time monitoring structure 4 in various complex environments, reducing the possibility of misjudging the risk of the container truck being lifted due to unclear visibility.

[0033] Specifically, such as Figure 6 As shown, the inner wall of the protective plate 9 is provided with a threaded rod 10, and the surface of the threaded rod 10 is threadedly connected to a movable block 11.

[0034] Specifically, such as Figure 6 As shown, a fixed frame 12 is bolted to the bottom of the movable block 11, and the surface of the cleaning mechanism 3 is engaged with the inner wall of the fixed frame 12.

[0035] Specifically, such as Figure 7 As shown, the cleaning mechanism 3 includes a scraper 301, a mounting plate 302, and an insert 303. The side of the insert 303 closest to the mounting plate 302 is bolted to the mounting plate 302. The side of the scraper 301 closest to the mounting plate 302 is bolted to the mounting plate 302. The surface of the insert 303 is inserted into the inner wall of the fixing frame 12. The side of the scraper 301 closest to the transparent plate 202 is in contact with the transparent plate 202.

[0036] In this embodiment: the threaded rod 10 on the inner wall of the protective plate 9 is threadedly connected to the movable block 11, so that the movable block 11 can adjust its displacement according to the rotation of the threaded rod 10. The fixed frame 12 bolted to the bottom of the movable block 11 provides a stable installation base for the cleaning mechanism 3, ensuring that the cleaning mechanism 3 remains stable during operation. The insert block 303 of the cleaning mechanism 3 is inserted into the inner wall of the fixed frame 12, ensuring the reliability of the connection. The scraper 301 is in close contact with the transparent plate 202. When the movable block 11 drives the fixed frame 12 to move, the scraper 301 can thoroughly and effectively clean the surface of the transparent plate 202, thereby ensuring that the transparent plate 202 is always in a clear state, providing an unobstructed and clear view for the real-time monitoring structure 4, and further ensuring the accurate judgment of the anti-lifting operation of the truck.

[0037] Specifically, such as Figure 7 As shown, a knob 13 is movably connected to the inner wall of the fixing bracket 12, and the surface of the knob 13 is threadedly connected to the inner wall of the insert block 303.

[0038] Specifically, such as Figure 7 As shown, the inner wall of the fixing bracket 12 has a through hole 14 for use with the knob 13, and the inner wall of the fixing bracket 12 has a slot 15 for use with the insert block 303.

[0039] In this embodiment, the knob 13, which is movably connected to the inner wall of the fixing frame 12, is threadedly connected to the inner wall of the insert 303. By rotating the knob 13, the insertion and removal of the insert 303 in the slot 15 of the fixing frame 12 can be easily controlled. This setting facilitates the installation and disassembly of the cleaning mechanism 3, and allows for quick replacement when the scraper 301 is worn or requires maintenance. At the same time, the threaded connection between the knob 13 and the insert 303 ensures the stable installation of the insert 303 in the fixing frame 12, preventing loosening during operation, ensuring the stable operation of the cleaning mechanism 3, maintaining the cleaning effect on the transparent plate 202, and continuously ensuring a clear view of the real-time monitoring structure 4.

[0040] Specifically, such as Figure 6 As shown, the inner wall of the protective plate 9 is bolted with a mounting block 16, and the threaded rod 10 is rotatably connected to the mounting block 16.

[0041] Specifically, such as Figure 6 As shown, an output assembly 17 is bolted to the rear side of the mounting block 16, and the output end of the output assembly 17 is bolted to the front side of the threaded rod 10.

[0042] In this embodiment: the mounting block 16 bolted to the inner wall of the protective plate 9 provides a stable rotation support point for the threaded rod 10, ensuring the stability of the threaded rod 10 during rotation. The connection between the output component 17 and the threaded rod 10 allows the rotation of the threaded rod 10 to be controlled by the output component 17. By driving the output component 17, the position of the movable block 11 can be flexibly adjusted, thereby flexibly adjusting the working position of the cleaning mechanism 3, realizing targeted cleaning of different areas of the transparent plate 202, meeting the cleaning needs of the transparent plate 202 under different conditions, and improving the reliability and adaptability of the truck anti-lifting device.

[0043] Working Principle: During the use of the hoisting structure 1 and the real-time monitoring structure 4, a protective mechanism 2 is installed. The protective frame 201 in the protective mechanism 2 is bolted to the protective plate 9, providing a stable support frame for the overall protection. The bolted connection between the inclined plate 203 and the protective frame 201 effectively guides rainwater and other liquids to slide down quickly, preventing them from accumulating on the protective frame 201 and reducing the risk of corrosion to the protective mechanism 2 and the internal real-time monitoring structure 4. The transparent plate 202 is fixed to the inner wall of the protective frame 201, ensuring that the real-time monitoring structure 4 has an unobstructed view and can clearly observe the status of the truck and container, while blocking external debris, dust, and wind and rain from directly contacting the real-time monitoring structure 4, thus protecting it in the harsh outdoor port environment. It can still operate stably under various conditions, ensuring that the accuracy and continuity of the anti-lifting work of the truck are not affected by external natural factors. By setting up a cleaning mechanism 3, which is closely attached to the transparent plate 202, when dirt appears on the surface of the transparent plate 202, it can continuously and effectively remove dust and other pollutants attached to the surface of the transparent plate 202. This can prevent dust accumulation from affecting the visibility of the real-time monitoring structure 4, ensuring that the image information it acquires is always clear and accurate, and providing a reliable basis for judging the separation status of the truck and the container. In cooperation with the protection mechanism 2, the cleaning mechanism 3 further ensures the stable operation of the real-time monitoring structure 4 in various complex environments, reducing the possibility of misjudging the risk of the truck being lifted due to unclear visibility.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
