Description

Technical Field

[0001] This utility model relates to the technical field of automated warehouses, specifically a protective device for automated warehouses. Background Technology

[0002] Automated storage and retrieval systems (AS / RS) are a new concept in logistics warehousing. Utilizing AS / RS equipment enables rational high-level warehouse operations, automated storage and retrieval, and simplified operation; AS / RS represent a high level of current technology. The main components of an AS / RS consist of racking, aisle-type stacker cranes, inbound / outbound workstations, and an automated transport and control system.

[0003] However, when transporting light goods, existing automated warehouses are prone to problems if foreign objects fall onto the bottom guide rails and get stuck on the chassis of the transport vehicle, causing the vehicle to stop working. Once the vehicle stops working, the entire transport line will be shut down. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for automated warehouses, which solves the problem that foreign objects are easily stuck on the chassis of transport vehicles, causing the transport vehicles to stop working, and improves the efficiency of transporting goods.

[0005] To achieve the above objectives, the utility model employs the following technical solution:

[0006] A protective device for an automated warehouse includes shields symmetrically arranged at the head of a transport vehicle. The head of the transport vehicle is provided with a spring-loaded structure, a fixed frame, and a fixed post rotatably connected to the shields. The spring-loaded structure includes a guide post arranged on the fixed frame and a slider slidably connected to the guide post. A return spring is sleeved on the outer side of the guide post and is arranged between the slider and the fixed frame. First support rods are rotatably connected to both sides of the slider, and the ends of the first support rods are rotatably connected to the shields. A fixed block that contacts the slider is threaded onto the guide post.

[0007] Furthermore, the springback structure comprises several components.

[0008] Furthermore, it also includes a movable frame that is slidably connected to several guide posts, and the return spring is disposed between the movable frame and the slider.

[0009] Furthermore, a slide rod is slidably connected to the fixed frame, and the slide rod is provided with a convex ring that contacts one side of the movable frame, and a nut that is threadedly connected to the other side of the movable frame.

[0010] Furthermore, the slide bar is provided with a slide groove and several limiting grooves, and a connecting groove is provided between the slide groove and several limiting grooves. It also includes a limiting ring that is rotatably mounted on the fixed frame and slidably connected to the slide bar. The limiting ring is provided with a limiting block, and the limiting block is slidably mounted between the slide groove, the connecting groove and the limiting groove in sequence.

[0011] Furthermore, a first connecting rod is rotatably connected to both sides of the slider, and a second support rod is connected to the end of the first connecting rod. The second support rod is rotatably connected to the baffle.

[0012] Furthermore, a second connecting rod is provided between the first support rod and the second support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In the initial state, the rebound force generated by the compression of the return spring drives the slider to slide on the guide post until the slider contacts the fixed block on the guide post. At the same time, since the two ends of the first support rod are rotatably connected to the slider and the baffle respectively, the baffle is driven to rotate around the fixed post until the overall structure tends to be a stable whole, thus fixing the baffle on the top of the transport vehicle. In addition, by rotating the fixed block, the position of the fixed block on the guide post is adjusted, thereby adjusting the initial position of the baffle, so that the baffle is tilted at the head of the transport vehicle, while avoiding interference between the baffle and the wheels of the transport vehicle, thus ensuring the normal driving of the transport vehicle.

[0015] 2. When the transport vehicle encounters an obstacle, the resulting resistance will cause the corresponding baffle to rotate around the fixed column. At the same time, the force is transmitted to the slider through the first support rod, causing the slider to slide on the guide column and further compressing the return spring between the slider and the fixed frame. The rebound force generated after the return spring is compressed is transmitted to the obstacle through the slider, the first support rod and the baffle. Because the baffle is tilted, the force component causes the obstacle to move to both sides, preventing fallen goods or other obstacles from continuously affecting the normal driving of the transport vehicle, thereby improving the efficiency of the transport vehicle in transporting goods.

[0016] 3. By setting the spring coefficient of the return spring, the return spring can be kept in a taut state under normal conditions. This ensures that the rebound force generated after the return spring is compressed always acts on the slider, preventing the slider from swinging back and forth on the guide post under the action of external force, which would affect the stability of the overall structure and further improve the efficiency of the transport vehicle in transporting goods.

[0024] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0025] This utility model provides a protective device for automated warehouses, such as... Figures 1-2As shown, the structure includes a shield 2 symmetrically arranged at the head of the transport vehicle 1. The head of the transport vehicle 1 is equipped with a spring-loaded structure, a fixing frame 3, and a fixing post 4 rotatably connected to the shield 2. The spring-loaded structure includes a guide post 5 mounted on the fixing frame 3 and a slider 6 slidably connected to the guide post 5. A return spring 7 is sleeved on the outer side of the guide post 5. By setting the spring coefficient of the return spring 7, it is ensured that the return spring 7 is in a taut state under normal conditions, so that the spring-loaded force generated after the return spring 7 is compressed always acts on the slider 6, preventing the slider 6 from swinging back and forth on the guide post 5 under external force, which would affect the stability of the overall structure and further improve the efficiency of the transport vehicle 1 in transporting goods. The return spring 7 is located between the slider 6 and the fixing frame 3, and the two sides of the slider 6 are rotatably connected to a first support rod 8. The end of the first support rod 8 is rotatably connected to the baffle 2, and the guide post 5 is threaded with a fixing block 9 that contacts the slider 6. In the initial state, the rebound force generated by the compression of the return spring 7 drives the slider 6 to slide on the guide post 5 until the slider 6 contacts the fixing block 9 on the guide post 5. At the same time, since the two ends of the first support rod 8 are rotatably connected to the slider 6 and the baffle 2 respectively, the baffle 2 is driven to rotate around the fixing post 4 until the overall structure tends to be stable, thus fixing the baffle 2 on the top of the transport vehicle 1. In addition, by rotating the fixing block 9, the position of the fixing block 9 on the guide post 5 is adjusted, thereby adjusting the initial position of the baffle 2, so that the baffle 2 is tilted at the head of the transport vehicle 1, while avoiding interference between the baffle 2 and the wheels of the transport vehicle 1, thus ensuring the normal driving of the transport vehicle 1.

[0026] When the transport vehicle 1 encounters an obstacle, the resulting resistance will cause the corresponding baffle 2 to rotate around the fixed post 4. At the same time, the force is transmitted to the slider 6 through the first support rod 8, causing the slider 6 to slide on the guide post 5 and further compressing the return spring 7 between the slider 6 and the fixed frame 3. The rebound force generated after the return spring 7 is compressed is transmitted to the obstacle through the slider 6, the first support rod 8 and the baffle 2. Because the baffle 2 is tilted, the force component causes the obstacle to move to both sides, preventing fallen goods or other obstacles from continuously affecting the normal driving of the transport vehicle 1, thereby improving the efficiency of the transport vehicle 1 in transporting goods.

[0027] Preferred, such as Figure 2 As shown, there are several rebound structures. Multiple rebound structures can better support the cover 2, improve the stability of the overall structure, and thus improve the efficiency of the transport vehicle 1 in transporting goods.

[0028] Preferred, such as Figure 2As shown, it also includes a movable frame 10 slidably connected to several guide posts 5, which guides the movable frame 10 as it slides on the fixed frame 3. The return spring 7 is disposed between the movable frame 10 and the slider 6. By sliding the movable frame 10 on the fixed frame 3, the compression of the return spring 7 can be adjusted, ensuring that the return spring 7 can still apply sufficient thrust to the slider 6 after long-term use. This prevents the slider 6 from swinging back and forth on the guide posts 5 under external force, which would affect the stability of the overall structure. This improves the efficiency of the transport vehicle 1 in transporting goods, extends the service life of the protective device, and reduces the cost of maintaining the protective device.

[0029] Preferred, such as Figure 2 As shown, a slide rod 11 is slidably connected to the fixed frame 3. The slide rod 11 is provided with a protruding ring 12 that contacts one side of the movable frame 10, and a nut 13 that is threadedly connected to the other side of the movable frame 10. By sliding the slide rod 11 on the fixed frame 3, the protruding ring 12 or the nut 13 at the end of the slide rod 11 contacts the movable frame 10 respectively. The resulting force drives the movable frame 10 to move together with the slide rod 11, thereby adjusting the compression of the return spring 7. At the same time, the nut 13 can be removed from the slide rod 11 for easy installation and maintenance of the slide rod 11.

[0030] Preferred, such as Figure 2 , Figure 3 and Figure 4 As shown, the slide rod 11 is provided with a slide groove 14 and a plurality of limiting grooves 15. A connecting groove 16 is provided between the slide groove 14 and the plurality of limiting grooves 15. It also includes a limiting ring 17 rotatably disposed on the fixed frame 3 and slidably connected to the slide rod 11. The limiting ring 17 is provided with a limiting block 18. The limiting block 18 is slidably disposed between the slide groove 14, the connecting groove 16 and the limiting groove 15 in sequence. By rotating the limiting ring 17, the limiting block 18 provided on the limiting ring 17 is located in the slide groove 14, so that the slide rod 11 can rotate relative to the limiting ring 17, thereby adjusting the position of the slide rod 11 on the fixed frame 3.

[0031] After adjusting the position of the slide rod 11 on the fixed frame 3, fine-tune the position of the slide rod 11 until the limiting block 18 on the limiting ring 17 corresponds to the nearest connecting groove 16 on the slide rod 11. Then, rotate the limiting ring 17 on the fixed frame 3 to move the limiting block 18 along with it, so that it moves from the sliding groove 14 into the connecting groove 16 until it moves onto the limiting groove 15. Then, remove the force applied to the limiting ring 17. Under the action of the return spring 7, the movable frame 10 and the slide rod 11 will be moved on the fixed frame 3. The sliding mechanism allows the slide bar 11 to move relative to the limiting ring 17 until the limiting block 18 is completely slid into the limiting groove 15. The resistance generated by the contact between the limiting block 18 and the limiting groove 15, as well as the rebound force applied by the return spring 7, restricts the slide bar 11 from sliding on the fixed frame 3, preventing external forces from unintentionally changing the position of the movable frame 10. This improves the stability of the overall structure, increases the efficiency of the transport vehicle 1 in transporting goods, simplifies the operation steps of fixing the slide bar 11, and improves the efficiency of adjusting the position of the slide bar 11 on the fixed frame 3.

[0032] Preferred, such as Figure 2 As shown, the slider 6 is rotatably connected to the two sides of the first connecting rod 19, and the end of the first connecting rod 19 is connected to the second support rod 20. The second support rod 20 is rotatably connected to the baffle 2, which strengthens the support of the baffle 2, improves the stability of the overall structure, and thus improves the efficiency of the transport vehicle 1 in transporting goods.

[0033] Preferred, such as Figure 2 As shown, a second connecting rod 21 is provided between the first support rod 8 and the second support rod 20 to further strengthen the support of the cover 2, improve the stability of the overall structure, and thus improve the efficiency of the transport vehicle 1 in transporting goods.

[0034] Example 1

[0035] This utility model provides a protective device for automated warehouses, such as... Figures 1-2 As shown, in the initial state, the rebound force generated by the compression of the return spring 7 drives the slider 6 to slide on the guide post 5 until the slider 6 contacts the fixing block 9 on the guide post 5. At the same time, since the two ends of the first support rod 8 are rotatably connected to the slider 6 and the baffle 2 respectively, the baffle 2 is driven to rotate around the fixing post 4 until the overall structure tends to be stable, thus fixing the baffle 2 on the top of the transport vehicle 1. In addition, by rotating the fixing block 9, the position of the fixing block 9 on the guide post 5 is adjusted, thereby adjusting the initial position of the baffle 2, so that the baffle 2 is tilted at the head of the transport vehicle 1, while avoiding interference between the baffle 2 and the wheels of the transport vehicle 1, thus ensuring the normal driving of the transport vehicle 1.

[0036] When the transport vehicle 1 encounters an obstacle, the resulting resistance will cause the corresponding baffle 2 to rotate around the fixed column 4. At the same time, the force is transmitted to the slider 6 through the first support rod 8, causing the slider 6 to slide on the guide column 5 and further compressing the return spring 7 between the slider 6 and the fixed frame 3. The rebound force generated after the return spring 7 is compressed is transmitted to the obstacle through the slider 6, the first support rod 8 and the baffle 2. Since the baffle 2 is tilted, the force component causes the obstacle to move to both sides, preventing the falling goods or other obstacles from continuously affecting the normal driving of the transport vehicle 1, thereby improving the efficiency of the transport vehicle 1 in transporting goods.

[0037] In addition, by setting the spring coefficient of the return spring 7, the return spring 7 is kept in a taut state under normal conditions, so that the rebound force generated after the return spring 7 is compressed always acts on the slider 6, avoiding the slider 6 from swinging back and forth on the guide post 5 under the action of external force, which would affect the stability of the overall structure and further improve the efficiency of the transport vehicle 1 in transporting goods.

[0038] Example 2

[0039] Based on Example 1, such as Figure 2 As shown, there are several spring-loaded structures. A first connecting rod 19 is rotatably connected to both sides of the slider 6. A second support rod 20 is connected to the end of the first connecting rod 19. The second support rod 20 is rotatably connected to the baffle 2. A second connecting rod 21 is provided between the first support rod 8 and the second support rod 20 to further strengthen the support for the baffle 2, improve the stability of the overall structure, and thus improve the efficiency of the transport vehicle 1 in transporting goods. Multiple spring-loaded structures can better support the baffle 2, improve the stability of the overall structure, and thus improve the efficiency of the transport vehicle 1 in transporting goods.

[0040] Example 3

[0041] Based on Example 2, such as Figure 2 , Figure 4 and Figure 4 As shown, rotating the limiting ring 17 causes the limiting block 18 on the limiting ring 17 to be located in the slide groove 14, allowing the slide rod 11 to rotate relative to the limiting ring 17. Then, the slide rod 11 is slid on the fixed frame 3, causing the protruding ring 12 or nut 13 at the end of the slide rod 11 to contact the movable frame 10 respectively. The resulting component force drives the movable frame 10 to move together with the slide rod 11, thereby adjusting the compression of the return spring 7. This ensures that the return spring 7 can still apply sufficient thrust to the slider 6 after long-term use, preventing the slider 6 from swinging back and forth on the guide post 5 under the action of external force, affecting the stability of the overall structure, thereby improving the efficiency of the transport vehicle 1 in transporting goods, extending the service life of the protective device, and reducing the cost required to maintain the protective device.

[0042] After adjusting the position of the slide rod 11 on the fixed frame 3, fine-tune the position of the slide rod 11 until the limiting block 18 on the limiting ring 17 corresponds to the nearest connecting groove 16 on the slide rod 11. Then, rotate the limiting ring 17 on the fixed frame 3 to move the limiting block 18 along with it, so that it moves from the sliding groove 14 into the connecting groove 16 until it moves onto the limiting groove 15. Then, remove the force applied to the limiting ring 17. Under the action of the return spring 7, the movable frame 10 and the slide rod 11 will be moved on the fixed frame 3. The sliding mechanism allows the slide bar 11 to move relative to the limiting ring 17 until the limiting block 18 is completely slid into the limiting groove 15. The resistance generated by the contact between the limiting block 18 and the limiting groove 15, as well as the rebound force applied by the return spring 7, restricts the slide bar 11 from sliding on the fixed frame 3, preventing external forces from unintentionally changing the position of the movable frame 10. This improves the stability of the overall structure, increases the efficiency of the transport vehicle 1 in transporting goods, simplifies the operation steps of fixing the slide bar 11, and improves the efficiency of adjusting the position of the slide bar 11 on the fixed frame 3.
