Description

Technical Field

[0001] This utility model belongs to the field of mining warning technology and relates to a safety warning device for ore unloading operations. Background Technology

[0002] Unloading operations refer to the process of unloading materials (such as ore, coal, sand, etc.) loaded on transport vehicles (such as trains, trucks, ships, etc.) to designated locations or equipment. Depending on the unloading method, unloading operations can be divided into several types, including mechanical unloading and manual unloading. Commonly used equipment and tools for unloading operations include cranes, grab buckets, conveyor belts, and loaders. The selection of these equipment and tools should be determined based on specific unloading needs and the working environment. For example, cranes are suitable for unloading large materials, grab buckets are often used for grabbing bulk materials, and conveyor belts are used to continuously transport materials to designated locations. Warning signs are often required to warn of any issues in the work area during unloading operations.

[0003] The following technical problems were found in the existing technology: the existing warning signs are placed directly at the edge of the area that needs to be warned, but in outdoor environments, wind often blows, and the signs cannot be placed stably, causing them to be blown down and thus failing to play their warning role in a timely manner. Utility Model Content

[0004] The technical problem this utility model aims to solve is that existing warning signs are placed directly at the edge of the area that needs to be warned, but in outdoor environments, wind often blows, making it difficult to place the signs securely, causing them to be blown over and thus failing to serve their warning purpose in a timely manner.

[0005] The present invention discloses a safety warning device for ore unloading operations, comprising a warning sign, with fixed frames on both sides of the warning sign, and a supporting column fixed to the lower end of each fixed frame. A drive shaft is rotatably connected to the inner side of each fixed frame, with the top end of the drive shaft extending to the outer side of the top end of the fixed frame and the lower end extending to the inner side of the supporting column. The drive shaft and the supporting column are rotatably connected. A drive fan blade is provided at the top of the fixed frame, and the drive fan blade is connected to the drive shaft via a plug-in assembly. Fixed components are provided on the inner sides of both ends of the supporting column for use with the drive fan blade. Foot plates are fixed to the lower ends of both ends of the supporting column.

[0006] The fixing component includes an extension rod disposed on the inner side of the support base column and slidably connected to the support base column. One end of the extension rod extends to the outer side of the support base column, and a fixing block is fixed to the outer end of the extension rod. A rotating wheel is rotatably connected to the lower end of the fixing block. A limit plate is fixed to the other end of the support base column and slidably connected to the support base column. The transmission shaft is connected to the limit plate through a transmission component.

[0007] The transmission assembly includes a drive bevel gear, which is fixed at one end of the transmission shaft located inside the support column. A built-in threaded rod is fixed on the side of the limiting plate near the drive bevel gear. A drive screw is threadedly connected to the inner side of the end of the built-in threaded rod away from the limiting plate. A transmission bevel gear is fixed to the end of the drive screw near the drive bevel gear. The transmission bevel gear meshes with the drive bevel gear.

[0008] A transmission rack is fixed to one side of the extension rod located inside the support column. A transmission screw is vertically arranged inside the support column at a position corresponding to the transmission rack. The transmission screw is rotatably connected to the support column. A transmission gear is fixed at a position corresponding to the transmission rack on the transmission screw. The transmission gear meshes with the transmission rack. A ground insertion rod is fixed to the lower end of the transmission screw. The lower end of the ground insertion rod extends to the outer side of the lower end of the support column.

[0009] The top of the grounding rod is fixed with an anti-detachment plate, and multiple positioning blocks are evenly fixed on the outer side of the grounding rod. The grounding rod is slidably connected to the supporting base column through the positioning blocks.

[0010] The plug-in assembly includes a connecting block, which is fixed at the top of the drive shaft. Multiple connecting slots are evenly distributed on the outer side of the connecting block. A plug-in block is provided on the inner side of the drive fan blade at a position corresponding to the connecting slot. The plug-in block is slidably connected to the drive fan blade. The plug-in block is plugged into the connecting block through the connecting slot. A plug-in spring is fixed at the end of the plug-in block away from the connecting block. The end of the plug-in spring away from the plug-in block is fixedly connected to the drive fan blade.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the coordinated structural design of the drive fan blade, transmission shaft and fixing components, the drive fan blade can be driven to rotate in windy weather. When the drive fan blade rotates, the transmission shaft drives the fixing components to improve the stability of the warning sign and the fixing frame, thereby improving the wind resistance of the device and effectively reducing the occurrence of the device being blown over in windy weather.

[0012] The plug-in component design allows the drive blades to be disassembled from the transmission shaft when the device needs to be transported. This reduces the risk of the extension rod and fixing block protruding from the inside of the support column due to the rotation of the drive blades during transportation, thus reducing damage to the extension rod and fixing block from foreign objects. It also reduces the space occupied by the device, thereby improving the convenience of transporting the device. Attached Figure Description

[0020] Example 1

[0021] like Figures 1-6As shown, the device includes a warning sign 1, with fixed brackets 2 on both sides of the warning sign 1. A support column 3 is fixed to the lower end of the fixed bracket 2. A drive shaft 9 is rotatably connected to the inner side of the fixed bracket 2. The top end of the drive shaft 9 extends to the outer side of the top end of the fixed bracket 2, and the lower end of the drive shaft 9 extends to the inner side of the support column 3. The drive shaft 9 and the support column 3 are rotatably connected. In order to drive the drive shaft 9 to rotate in the presence of wind, a drive fan blade 4 is provided at the top end of the fixed bracket 2. The drive fan blade 4 is connected to the drive shaft 9 through a plug-in assembly. In order to stabilize the device, fixed components are provided on the inner sides of both ends of the support column 3 for use with the drive fan blade 4. Foot 5 is fixed to the lower ends of both ends of the support column 3.

[0022] The coordinated structure design of the drive fan blade 4, transmission shaft 9, and fixing components enables the drive fan blade 4 to rotate in windy weather. When the drive fan blade 4 rotates, the transmission shaft 9 drives the fixing components to improve the stability of the warning sign 1 and the fixing frame 2, thereby improving the wind resistance of the device and effectively reducing the occurrence of the device being blown over in windy weather.

[0023] Example 2

[0024] like Figure 2 , Figure 5 and Figure 6 As shown, the fixing assembly includes an extension rod 6, which is disposed inside the support base column 3 and slidably connected to the support base column 3. One end of the extension rod 6 extends to the outside of the support base column 3, and a fixing block 7 is fixed to the end of the extension rod 6 located outside the support base column 3. To facilitate the movement of the fixing block 7, a rotating wheel 8 is rotatably connected to the lower end of the fixing block 7. To prevent the extension rod 6 from moving out of the inside of the support base column 3, a limiting plate 18 is fixed to the other end of the support base column 3. The limiting plate 18 is slidably connected to the support base column 3. In order to drive the limiting plate 18 and the extension rod 6 to move when the drive shaft 9 rotates, the drive shaft 9 and the limiting plate 18 are connected through a transmission assembly.

[0025] The transmission assembly includes a drive bevel gear 14, which is fixed to one end of the transmission shaft 9 located inside the support column 3. In order to move the limiting plate 18, a built-in threaded rod 17 is fixed to the side of the limiting plate 18 near the drive bevel gear 14. In order to move the built-in threaded rod 17, a drive screw 16 is threadedly connected to the inner side of the end of the built-in threaded rod 17 away from the limiting plate 18. In order to rotate the drive screw 16, a transmission bevel gear 15 is fixed to the end of the drive screw 16 near the drive bevel gear 14. The transmission bevel gear 15 meshes with the drive bevel gear 14.

[0026] An extension rod 6 is fixed to a transmission rack 19 on one side inside the support column 3. A transmission screw 20 is vertically arranged inside the support column 3 at a position corresponding to the transmission rack 19. To facilitate the rotation of the transmission screw 20 when the extension rod 6 moves, the transmission screw 20 is rotatably connected to the support column 3. A transmission gear 21 is fixed at a position corresponding to the transmission rack 19 on the transmission screw 20. The transmission gear 21 meshes with the transmission rack 19. To improve the stability of the support column 3, a ground insertion rod 22 is fixed to the lower end of the transmission screw 20. The lower end of the ground insertion rod 22 extends to the outer side of the lower end of the support column 3. To prevent the ground insertion rod 22 from moving out of the inside of the support column 3, an anti-detachment plate 24 is fixed to the top of the ground insertion rod 22. To limit the rotation of the ground insertion rod 22, multiple positioning blocks 23 are evenly fixed to the outer side of the ground insertion rod 22. The ground insertion rod 22 is slidably connected to the support column 3 through the positioning blocks 23.

[0027] During operation, in windy conditions, the drive fan blade 4 drives the transmission shaft 9 to rotate. When the transmission shaft 9 rotates, it drives the drive bevel gear 14 and the transmission bevel gear 15 meshing with it, which in turn drives the drive screw 16 fixed to the transmission bevel gear 15 to rotate. When the drive screw 16 rotates, it drives the limiting plate 18 fixed to the internal threaded rod 17, which is threaded to it, to move away from the internal threaded rod 17. When the limiting plate 18 moves, it drives the extension rod 6 and the fixing block 7 to move simultaneously. This increases the length of the support column 3 by extending the extension rod 6 and the fixing block 7, thereby improving the stability of the device. At the same time, when the extension rod 6 moves, it drives the transmission screw 20 to rotate through the transmission rack 19 and the transmission gear 21 meshing with the transmission rack 19. When the transmission screw 20 rotates, it drives the ground insertion rod 22, which is threaded to it, to move along the axial direction of the transmission screw 20, thereby inserting the ground insertion rod 22 into the ground, which further improves the stability of the device.

[0028] Example 3

[0029] like Figure 3 Figure 4 As shown, the plug-in assembly includes a connecting block 10, which is fixed at the top of the drive shaft 9. Multiple connecting slots 11 are evenly provided on the outer side of the connecting block 10. To facilitate the connection between the drive fan blade 4 and the connecting block 10, a plug-in block 12 is provided on the inner side of the drive fan blade 4 at a position corresponding to the connecting slot 11. The plug-in block 12 is slidably connected to the drive fan blade 4. The plug-in block 12 is plugged into the connecting block 10 through the connecting slot 11. A plug-in spring 13 is fixed at the end of the plug-in block 12 away from the connecting block 10. The end of the plug-in spring 13 away from the plug-in block 12 is fixedly connected to the drive fan blade 4.

[0030] When it is necessary to disassemble the drive fan blade 4, the drive fan blade 4 can be moved directly away from the connecting block 10. When the drive fan blade 4 moves, it will squeeze the plug block 12, causing the plug block 12 to move closer to the plug spring 13. When the plug block 12 moves to the point of disengaging from the connecting groove 11, the connecting block 10 will release the limiting effect on the plug block 12, thereby allowing the drive fan blade 4 to be removed from the outside of the connecting block 10, completing the disassembly of the drive fan blade 4.
