Description

Technical Field

[0001] This utility model relates to the field of unloading assistance technology, and in particular to an unloading assistance device for logistics. Background Technology

[0002] In logistics warehousing, freight stations and other scenarios, manual unloading has problems such as low efficiency, high labor intensity and easy damage to goods and personnel. Unloading auxiliary devices for logistics can significantly improve unloading efficiency and reduce operational risks through mechanical structure, automation technology or human-machine collaboration design, and are key equipment in modern logistics operation processes.

[0003] Most logistics unloading auxiliary devices currently on the market have a significant shortcoming: they cannot extend into the interior of truck compartments. Traditional conveyor belt unloading auxiliary devices have fixed lengths and structures, and can only connect at the rear of the compartment, unable to penetrate deep into the compartment. This forces workers to first move the goods from the back of the compartment to the rear before they can be transported by the conveyor belt, making the process extremely laborious and significantly reducing unloading efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1 To be continued Figure 4As shown: A logistics unloading auxiliary device includes a set of frames 1, on which a conveying assembly 2 is mounted. The conveying assembly 2 includes a first roller 213 rotatably connected between the sets of frames 1 and a first motor 212 mounted on the outer surface of one of the frames 1. The output end of the first motor 212 is connected to one end of the first roller 213. A second roller 214 is mounted on one side of the first roller 213, and a third roller 215 is mounted below the first roller 213. A conveyor belt 201 is fitted around the first roller 213, the second roller 214, and the third roller 215. When it is necessary to move goods from a vehicle, the first motor 212 is controlled to operate. 212 can drive the first roller 213 to rotate. Under the transmission action, the first roller 213 will drive the conveyor belt 201 to rotate. When the conveyor belt 201 rotates, it will drive the second roller 214 and the third roller 215 to rotate simultaneously. The unloading personnel can place the goods on the conveyor belt 201 to facilitate the transportation of the goods and reduce the physical strength consumed by the staff inside the carriage. A set of frame 1 has a guide plate 4 rotatably connected to the outer surface. When the goods are transported to the end of the conveyor belt 201, the staff can place the goods on the guide plate 4 and let them slide down to the ground along the tilt angle of the guide plate 4, which reduces the physical strength consumed by the ground staff in the handling process.

[0026] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown: The conveying assembly 2 also includes an adjustment mechanism located below the second roller 214 for adjusting the conveying distance of the conveyor belt 201. The adjustment mechanism includes a set of support plates 202 rotatably connected to the front and rear ends of the second roller 214. A movable plate 203 is fixedly connected to one side of the set of support plates 202 that are close to each other. The adjustment mechanism also includes a carrier plate 216 located below the second roller 214. One side of the carrier plate 216 is connected to the outer surface of a set of frame 1. A set of fixed plates 211 is fixedly connected to the upper surface of the carrier plate 216. A support roller 210 is rotatably connected between the set of fixed plates 211. The outer surface of the support roller 210 is in contact with the bottom surface of the conveyor belt 201. Through the support roller 210, the support roller 210 can support the conveyor belt 201, so that the conveyor belt 201 always maintains a certain distance from the adjustment mechanism, avoiding contact between the conveyor belt 201 and the adjustment mechanism during subsequent adjustment, and ensuring the normal operation of the conveying assembly 2.

[0027] As attached Figure 2 and attached Figure 3As shown: A second motor 204 is mounted on the upper surface of the carrier plate 216. A threaded rod 205 is fixedly connected to the output end of the second motor 204. A threaded sleeve 206 is threadedly connected to the outer surface of the threaded rod 205. The other end of the threaded sleeve 206 is connected to one side of the moving plate 203. When it is necessary to adjust the conveying distance of the conveyor belt 201, the second motor 204 is controlled to work. The second motor 204 can drive the threaded rod 205 to rotate. Under the transmission action, the threaded rod 205 will drive the threaded sleeve 206 to move. The threaded sleeve 206 will then push the moving plate 203 and the support plate 202 to move synchronously. The movement of the second roller 214 can drive the second roller 214 to move synchronously. When the second roller 214 moves forward, it will push the conveyor belt 201 to move and extend its transportation distance. Each support plate 202 is equipped with a moving wheel 3 at the bottom. The moving wheel 3 provides auxiliary support and movement for the conveyor belt 201, making the movement of the conveyor belt 201 more convenient. One side of the carrier plate 216 is slidably connected to a limit rod 5. The other end of the limit rod 5 is connected to the outer surface of the threaded sleeve 206. The limit rod 5 can guide the threaded sleeve 206, avoiding the deviation of the threaded sleeve 206 during movement and ensuring the normal operation of subsequent work.

[0028] As attached Figure 1 and attached Figure 4 As shown: A pulling mechanism for applying downward pulling force to the third roller 215 is provided below the third roller 215. The pulling mechanism includes a set of limiting blocks 208 rotatably connected to the front and rear ends of the third roller 215. A fixed frame 207 is slidably connected to the outer surface of each limiting block 208. One side of each fixed frame 207 is connected to the outer surface of the frame 1. When the conveyor belt 201 extends, the bottom of the other end will synchronously drive the third roller 215 to rise. The cooperation of the limiting blocks 208 and the fixed frames 207 can achieve stable and precise guidance of the third roller 215, preventing the third roller 215 from deviating during movement and ensuring the stability of the third roller 215. The conveyor belt operates smoothly with each limit block 208 having a fixed spring 209 on its bottom surface. The bottom end of each spring 209 is connected to the inner bottom wall of the fixed frame 207. The springs 209 apply a downward pulling force to the limit blocks 208, thereby causing the third roller 215 to pull the conveyor belt 201 downward to taut it. This ensures that the conveyor belt 201 maintains a stable tension, preventing sagging in the middle section due to increased extension length, ensuring normal transport of goods, and allowing adjustment of the transport distance of the conveyor belt 201. This reduces the distance that unloading personnel need to handle goods, significantly reduces the physical exertion of workers inside the vehicle, and effectively improves unloading efficiency.

[0029] Working principle: When goods need to be moved from deep inside the carriage, the first motor 212 is activated, driving the first roller 213 to rotate. The first roller 213, in turn, drives the conveyor belt 201 to rotate. The rotation of the conveyor belt 201 simultaneously drives the second roller 214 and the third roller 215. Unloading personnel place the goods on the conveyor belt 201 for transport. When the transport distance of the conveyor belt 201 needs adjustment, the second motor 204 is activated, driving the threaded rod 205 to rotate. The threaded rod 205, in turn, drives the threaded sleeve 20... When the threaded sleeve 206 moves, it will push the moving plate 203 and the support plate 202 at the other end to move synchronously. The movement of the support plate 202 can drive the second roller 214 to move synchronously. When the second roller 214 moves forward, it will push the conveyor belt 201 to move and extend its transportation distance. When the conveyor belt 201 extends, the bottom of the other end will drive the third roller 215 to rise synchronously, so that the conveyor belt 201 can form a taut shape, ensuring the normal transportation of goods. This realizes the adjustment of the transportation distance of the conveyor belt, thereby shortening the distance that unloading personnel need to carry goods, greatly reducing the physical strength consumed by the staff inside the carriage, and effectively improving the efficiency of unloading.
