Description

Technical Field

[0001] This utility model relates to the field of automobile loading and unloading, specifically to an automatic loading and unloading auxiliary device for tractor-trailers. Background Technology

[0002] In modern logistics and engineering operations, tractor-trailers play a crucial role, undertaking the transportation of large quantities of goods. However, in the actual use of tractor-trailers, the loading and unloading of goods has always been a key factor affecting transportation efficiency and cost. Traditionally, tractor-trailers rely mainly on manual operation or simple auxiliary tools when loading and unloading cylindrical items (such as steel pipes and timber). Manual loading and unloading is not only labor-intensive but also inefficient. Taking large construction sites as an example, a large number of steel pipes need to be loaded and unloaded daily for scaffolding construction. Workers need to spend a lot of time and energy on handling and stacking, which greatly restricts the progress of the project. At the same time, manual loading and unloading also poses a high safety risk. Because cylindrical items have smooth surfaces and irregular shapes, they are prone to slipping and rolling during handling, leading to worker injuries. Therefore, we propose an automatic loading and unloading auxiliary device for tractor-trailers. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides an automatic loading and unloading auxiliary device for tractor trucks, which solves the above-mentioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an automatic loading and unloading auxiliary device for tractor trucks, including a traction device, a mounting plate fixedly installed at one end of the traction device, a drive motor fixedly installed on the top of the mounting plate, two sets of workpiece placement slots opened on the top of the traction device, a feeding cylinder slidably installed in each of the two sets of workpiece placement slots, a connecting bridge fixedly connected between the two sets of feeding cylinders, and a piston rod on the drive motor fixedly connected to one side of the connecting bridge, further comprising:

[0005] An automatic loading and unloading assembly, mounted on a traction device, is used for loading and unloading cylindrical items.

[0006] Preferably, a vertical component plate is fixedly provided at one end of the top of the traction device, and support plates are fixedly connected to both sides of the component plate near the top.

[0007] Preferably, the two sets of workpiece placement slots are in the shape of half-cylinders, and the two sets of workpiece placement slots are opened at the top of the traction device near the two sides.

[0008] Preferably, the bottom inner walls of both sets of workpiece placement slots are rotatably equipped with several sets of equally spaced ball bearings.

[0009] Preferably, both sets of feeding cylinders have notches A at their bottoms for the passage of balls, and limit plates are fixedly connected to the outer walls of both sides of the feeding cylinder near the bottom. Limit grooves are opened on the inner walls of both sides of the workpiece placement groove, and the limit plates are slidably engaged in the limit grooves.

[0010] Preferably, the automatic loading and unloading assembly includes a connecting block A, a linkage rod, a connecting block B, a feeding tray, and an anti-drop tray. The top of each of the two sets of feeding cylinders is fixedly connected to a connecting block A, and a linkage rod is fixedly connected to one side of each of the two sets of connecting blocks A. The two sets of support plates are slidably sleeved on the outer walls of the two sets of linkage rods. The end of the linkage rod away from the connecting block A is sleeved with a connecting block B. A disc-shaped feeding tray is slidably installed inside each of the two sets of feeding cylinders. The two sets of feeding trays are fixedly connected to the bottom of the two sets of connecting blocks B. A circular anti-drop tray is fixedly connected to the side of the feeding tray near the feeding cylinder.

[0011] Preferably, the bottom of the two sets of feeding trays is provided with a notch B at the middle position for the ball to pass through, and the bottom of the two sets of anti-drop trays is provided with a notch C on the side of the notch B for the ball to pass through.

[0012] Compared with the prior art, the present invention provides an automatic loading and unloading auxiliary device for tractor trucks, which has the following beneficial effects:

[0013] 1. This automatic loading and unloading auxiliary device for tractor trucks uses a drive motor to power the connecting bridge, which in turn pushes the unloading cylinder and the loading tray to complete the loading and unloading actions, thus achieving automated operation. During unloading, it can quickly push cylindrical items out of the workpiece placement slot; during loading, the loading tray can also quickly push the items into the workpiece placement slot, greatly shortening the loading and unloading time, effectively improving the cargo turnover efficiency of the tractor truck, and making the entire transportation process smoother and more efficient.

[0014] 2. This automatic loading and unloading auxiliary device for tractor trucks completely replaces manual handling and stacking operations. Workers only need to perform simple auxiliary tasks such as starting the equipment and placing goods, which greatly reduces labor intensity. This not only helps protect the health of workers, but also improves their comfort and enthusiasm for work, and reduces work errors and safety accidents caused by overwork.

[0015] 3. This automatic loading and unloading auxiliary device for tractor trucks, through its reasonable structural design, ensures the stability and safety of the loading and unloading process. During the sliding process of the unloading cylinder and the loading tray, the limiting plate slides within the limiting groove, ensuring the linearity and stability of the movement and preventing the device from shaking or deviating during operation. Simultaneously, the anti-drop plate provides reliable support for cylindrical items during loading, preventing accidental drops during loading and unloading. These safety designs effectively reduce safety risks during loading and unloading, protecting the personal safety of workers.

[0016] 4. This automatic loading and unloading auxiliary device for tractor trucks allows cylindrical items to slide on the balls in the workpiece placement slot during loading and unloading, reducing friction between the item and the device and lowering the possibility of damage to the goods.

A connecting bridge 6 is fixedly connected between the two sets of feeding cylinders 5. The piston rod on the drive motor 3 is fixedly connected to one side of the connecting bridge 6. The device also includes:

[0023] An automatic loading and unloading assembly, which is mounted on the traction device 1, is used for loading and unloading cylindrical items.

[0024] A vertical component plate 7 is fixedly installed at one end of the top of the traction device 1, and support plates 8 are fixedly connected to both sides of the component plate 7 near the top.

[0025] The two sets of workpiece placement slots 4 are in the shape of half-cylinders and are located on the top of the traction device 1 near both sides.

[0026] Both sets of workpiece placement slots 4 have several sets of equally spaced ball bearings 11 rotatably installed on the bottom inner wall. The ball bearings 11 are rotatably installed on the bottom inner wall of the workpiece placement slot 4 and will not fall off.

[0027] Both sets of feeding cylinders 5 have notches A14 at the bottom for the ball bearings 11 to pass through. Limiting plates 13 are fixedly connected to the outer walls of both sides of the feeding cylinder 5 near the bottom. Limiting grooves 12 are opened on both sides of the inner walls of the workpiece placement groove 4. The limiting plates 13 are slidably engaged in the limiting grooves 12.

[0028] The automatic loading and unloading assembly includes a connecting block A9, a linkage rod 10, a connecting block B15, a feeding tray 16, and an anti-drop tray 18. The top of each of the two sets of feeding cylinders 5 is fixedly connected to a connecting block A9, and a linkage rod 10 is fixedly connected to one side of each of the two sets of connecting blocks A9. The two sets of support plates 8 are slidably sleeved on the outer walls of the two sets of linkage rods 10. The end of the linkage rod 10 away from the connecting block A9 is sleeved with a connecting block B15. A disc-shaped feeding tray 16 is slidably installed inside each of the two sets of feeding cylinders 5. The two sets of feeding trays 16 are fixedly connected to the bottom of the two sets of connecting blocks B15. A ring-shaped anti-drop tray 18 is fixedly connected to the side of the feeding tray 16 near the feeding cylinder 5.

[0029] The bottom of the two sets of feeding trays 16 has a notch B17 at the middle position for the ball 11 to pass through, and the bottom of the two sets of anti-drop trays 18 has a notch C19 on the side of the notch B17 for the ball 11 to pass through.

[0030] Partial description of the mechanism: Feeding cylinder 5: It is slidably installed in two sets of workpiece placement slots 4. A connecting bridge 6 is fixed between the two sets of feeding cylinders 5. The connecting bridge 6 is connected to the piston rod of the drive motor 3. Under the action of the drive motor 3, it slides in the workpiece placement slot 4 and pushes the cylindrical items to unload.

[0031] Support plate 8: Support plates 8 are fixedly connected to both sides of the component plate 7 near the top. The two sets of support plates 8 are slidably sleeved on the outer walls of the two sets of linkage rods 10 to provide support for the linkage rods 10, ensure the stability of the linkage rods 10 during the sliding process, and thus ensure the stable operation of the entire automatic loading and unloading component.

[0032] Linkage rod 10: Linkage rod 10 is fixedly connected to one side of each of the two sets of connecting blocks A9. A connecting block B15 is sleeved on the end of the linkage rod 10 away from the connecting block A9. The two sets of support plates 8 are respectively slidably sleeved on the outer wall of the two sets of linkage rods 10, which play the role of connecting and transmitting power, and transmitting the movement of the connecting block A9 to the connecting block B15.

[0033] Ball bearings 11: Several sets are evenly distributed on the bottom inner wall of the two sets of workpiece placement slots 4. When the cylindrical item slides in the workpiece placement slot 4, it rolls on the ball bearings 11, which reduces the friction between the cylindrical item and the workpiece placement slot 4 and makes the item slide more smoothly.

[0034] Limiting groove 12: It is formed on both sides of the inner wall of the workpiece placement groove 4. The limiting piece 13, which is fixed to the outer wall of both sides of the feeding cylinder 5 near the bottom, is slidably engaged in the limiting groove 12. It plays a limiting and guiding role in the sliding of the feeding cylinder 5, ensuring the stability and straightness of the feeding cylinder 5 during the sliding process.

[0035] Limiting plate 13: It is fixed to the outer walls of both sides of the feeding cylinder 5 near the bottom and slides into the limiting grooves 12 on the inner walls of both sides of the workpiece placement groove 4. It cooperates with the limiting grooves 12 to prevent the feeding cylinder 5 from shifting or shaking during the sliding process and to ensure the accuracy of the loading and unloading process.

[0036] Notch A14: It is opened at the bottom of the two sets of feed cylinders 5 to allow the ball bearings 11 to pass through, so as to avoid interference between the feed cylinder 5 and the ball bearings 11 when the feed cylinder 5 slides in the workpiece placement groove 4, and to ensure that the feed cylinder 5 can slide smoothly.

[0037] Connecting block B15: Connecting block B15 is sleeved on the end of the linkage rod 10 away from the connecting block A9. The two sets of feeding trays 16 are respectively fixed to the bottom of the two sets of connecting blocks B15. They move with the movement of the linkage rod 10, thereby driving the feeding trays 16 to perform loading and unloading operations.

[0038] The feeding tray 16 is disc-shaped and is slidably installed inside both sets of unloading cylinders 5. The two sets of feeding trays 16 are fixedly connected to the bottom of the two sets of connecting blocks B15. During loading, the feeding tray 16 pushes the cylindrical item into the workpiece placement groove 4; during unloading, it moves outward as the unloading cylinder 5 moves. A notch B17 is provided at the bottom center of the feeding tray 16 to allow the ball bearing 11 to pass through, preventing the feeding tray 16 from contacting the ball bearing 11 and causing motion interference when sliding in the workpiece placement groove 4.

[0039] Notch B17: It is opened at the bottom of the two sets of feeding trays 16 and is located in the middle position to allow the ball bearings 11 to pass through, so as to avoid interference between the feeding trays 16 and the ball bearings 11 during the sliding process and ensure that the feeding trays 16 can slide smoothly.

[0040] Anti-drop disc 18: Circular in shape, fixed to the side of the loading disc 16 near the unloading cylinder 5. During loading, it provides support for one end of cylindrical items, preventing accidental drop during loading and unloading, and ensuring safety during the process. A notch C19 is provided on the side of the bottom of the anti-drop disc 18 corresponding to the notch B17, allowing the ball bearing 11 to pass through, preventing interference between the anti-drop disc 18 and the ball bearing 11 during sliding.

[0041] Notch C19: It is opened on the side of the bottom of the two sets of anti-drop discs 18 corresponding to the notch B17, so that the ball 11 can pass through, avoiding interference between the anti-drop disc 18 and the ball 11 during the sliding process, and ensuring that the anti-drop disc 18 can slide smoothly.

[0042] Working principle: When unloading cylindrical items, the drive motor 3 is started first. The piston rod of the drive motor 3 pushes the connecting bridge 6, which in turn drives the two sets of unloading cylinders 5 to slide in the workpiece placement groove 4. The limiting plates 13 on the unloading cylinders 5 slide in the limiting grooves 12 to ensure the stability and straightness of the unloading cylinders 5 during sliding. The connecting block A9 drives the two sets of support plates 8 to slide on the support plates 8 through the movement of the unloading cylinders 5. The two sets of support plates 8 provide support force. The two sets of connecting blocks B15 drive the loading plate 16 to move outward with the movement of the linkage rod 10. When the unloading cylinders 5 slide in the workpiece placement groove 4, they push the cylindrical items outward. The cylindrical items slide on several sets of ball bearings 11 in the workpiece placement groove 4 to reduce the outward sliding of the cylindrical items. Due to friction, when one end of the two sets of unloading cylinders 5 slides out of the workpiece placement groove 4 near the loading plate 16, one end of the cylindrical item slides out of the workpiece placement groove 4 and falls to the ground. Then, it pushes forward against the connecting bridge 6, causing the other end of the cylindrical item to fall to the ground as well, thereby unloading the cylindrical item. When loading is required, one end of a new set of cylindrical items is placed on the bottom inner wall of the anti-drop plate 18, and the other end is placed at the port of the workpiece placement groove 4. The piston rod is retracted, causing the loading plate 16 to push the cylindrical item into the workpiece placement groove 4. Notches B17, C19, and A14 prevent the loading plate 16 and unloading cylinder 5 from contacting the ball bearing 11 and causing motion interference when sliding in the workpiece placement groove 4.
