Description

Technical Field

[0001] This application relates to the field of logistics equipment, and in particular to an unloading platform for loading and unloading trucks in a logistics system. Background Technology

[0002] Currently, with the rapid development of the logistics industry and the continuous expansion of logistics scale, warehousing systems, as an important part of modern logistics, have also developed well.

[0003] In order to facilitate the storage and transportation of large quantities of goods, existing warehouses usually have unloading platforms at the warehouse door. The unloading platform is usually higher than the ground and similar in height to the cargo box of a common truck. During the daily loading and unloading of trucks, a pad needs to be laid at the connection between the unloading platform and the cargo box of the truck.

[0004] The existing technical solutions mentioned above have the following drawbacks: Since common unloading platforms are usually made of cement, loading and unloading on the unloading platform for a long time will cause the surface of the unloading platform to become smooth. After laying a pad between the unloading platform and the truck bed, the pad is easy to slip when workers move over it while loading or unloading goods from the truck. This can easily cause people and goods to fall during the loading and unloading process, which is not conducive to the loading and unloading work of workers. Utility Model Content

[0005] In order to improve safety during loading and unloading, this application provides a loading / unloading platform for trucks in a logistics system.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A loading / unloading platform for trucks in a logistics system includes a loading / unloading platform body, a mounting plate vertically arranged and mounted against the vertical surface of the loading / unloading platform body, a first connecting mechanism with one end connected to the surface of the mounting plate, a second connecting mechanism with one end connected to the surface of the mounting plate and located below the first connecting mechanism, a first support frame with one end rotatably connected to the end of the first connecting mechanism away from the mounting plate, a second support frame with one end rotatably connected to the end of the first support frame away from the first connecting mechanism, a pad plate rotatably connected to the ends of the first connecting mechanism and the second support frame away from the first support frame, a locking mechanism disposed on the first support frame for limiting the rotation of the second support frame, and a flip plate rotatably disposed on the top of the mounting plate and capable of overlapping the pad plate.

[0008] By adopting the above technical solution, the mounting plate facilitates the unified and stable installation of components such as the connecting mechanism on the unloading platform body. The pad plate, through the cooperation of the first connecting mechanism, the first support frame, the second support frame, and the second connecting mechanism, allows the pad plate to rotate on the unloading platform body. The locking mechanism temporarily positions the rotated pad plate. When the truck stops near the unloading platform body, the locking mechanism releases the pad plate and allows it to overlap the rear end of the truck bed. Then, the flip plate overlaps the pad plate, covering the gap between the pad plate and the mounting plate. This facilitates loading and unloading of goods by workers on the flip plate and the pad plate. The flip plate and the pad plate are indirectly connected to the unloading platform body, maintaining the stability of the overlap. The flip plate and the pad plate are not prone to slippage when workers are loading and unloading goods, thus facilitating the loading and unloading of goods.

[0009] Optionally, the first connecting mechanism includes two spaced-apart first connecting plates, each fixed to a mounting plate at one end on the same side, a first fixed shaft fixed to the two first connecting plates, and a first rotating block rotatably mounted on the fixed shaft, the first rotating block being fixed to the mounting plate.

[0010] By adopting the above technical solution, the first connecting mechanism has a simple structure and can be stably connected between the mounting plate and the pad, thereby providing a stable installation foundation for the pad and improving the stability of the pad in use.

[0011] Optionally, the second connecting mechanism includes two spaced-apart second connecting plates, each fixed to a mounting plate at one end on the same side, and a second fixed shaft fixed between the two second connecting plates.

[0012] By adopting the above technical solution, the second connecting mechanism has a simple structure, can be stably connected to the mounting plate, and can also provide a stable installation foundation for the support frame.

[0013] Optionally, the distance between the second fixed shaft and the mounting plate is less than the distance between the first fixed shaft and the mounting plate.

[0014] By adopting the above technical solution, when loading and unloading goods without using a pallet, placing the pallet vertically can shorten the distance between the pallet and the mounting plate, making it easier to store the pallet.

[0015] Optionally, the first support frame includes two first support rods that are parallel to each other in the length direction and arranged at intervals, a first sleeve fixed to one end of the two first support rods on the same side, and a second sleeve fixed to the other end of the two first support rods on the same side. The first sleeve is rotatably sleeved on the second fixed shaft.

[0016] Optionally, the second support frame includes two second support rods that are parallel to each other in the length direction and arranged at intervals, a first connecting shaft fixedly connected to the same side end of the two second support rods, a second connecting shaft fixedly connected to the other same side end of the two second support rods, and a second rotating block rotatably disposed on the second connecting shaft. The second rotating block is fixedly connected to the pad and arranged at intervals from the first rotating block. The first connecting shaft is rotatably disposed in the second sleeve.

[0017] By adopting the above technical solution, the support rod, sleeve, and connecting shaft can facilitate the rotation of the pad while also facilitating the storage of the connecting mechanism, thus reducing the space occupied by the connecting mechanism.

[0018] Optionally, the locking mechanism includes a gear sleeved and fixedly mounted on the first connecting shaft, and a locking member fixedly mounted on the outer wall of the first support rod. The gear is located outside the two second support rods, and the locking end of the locking member can be inserted between the teeth of the gear.

[0019] By adopting the above technical solution, the second connecting shaft can be stably restricted through the plug-in engagement between the locking component and the gear, thereby providing stable support for the rotated pad. When the pad is attached to the rear end of the carriage, the restriction of the locking component on the gear is released, and the locking component can also be protected.

[0020] Optionally, the locking component includes a housing fixedly mounted on the outer wall of the first support rod with an open end and a closed end at its two ends, a cover plate fixedly mounted on the open end of the housing, a movable plate movably mounted inside the housing, a locking rod movably passing through the closed end of the housing and the cover plate and passing through and fixed to the movable plate, and a spring sleeved on the locking rod with its two ends abutting against the cover plate and the movable plate respectively. The end of the locking rod near the movable plate can be inserted between the teeth of the gear.

[0021] By adopting the above technical solution, the two ends of the spring abut against the cover plate and the movable plate respectively, which enables the locking rod to be stably inserted into the gear. When it is necessary to release the restriction of the pad, simply pull the end of the locking rod away from the gear. The overall structure of the locking component is simple, which can restrict the pad for a short time while also facilitating operation by the staff. By inserting the locking rod into different positions on the gear, the rotation angle of the pad can be selected according to the actual use, thereby facilitating the stable installation of the pad on the truck.

[0022] Optionally, the locking mechanism further includes a fixing ring fixedly disposed on the end of the locking rod away from the gear, a pull rope fixedly connected to the fixing ring at one end, a plurality of guide rings sleeved on the pull rope, and a pull ring fixedly disposed on the end of the pull rope away from the fixing ring.

[0023] By adopting the above technical solution, through the tensioning, fixing ring, guide ring and pull ring, it is possible for the operator to release the connection between the locking rod and the gear while rotating the pad, thus facilitating the operator's operation.

[0024] Optionally, handles are fixedly provided on the opposite sides of the pad.

[0025] By adopting the above technical solution, workers can easily rotate the pad by holding the handle.

[0026] In summary, this application has the following technical effects:

[0027] 1. By setting up a unloading platform body, mounting plate, first connecting mechanism, second connecting mechanism, first support frame, second support frame, pad, locking mechanism, and flipping plate, the pad can rotate on the unloading platform body, and the locking mechanism temporarily positions the rotated pad. When the truck stops near the unloading platform body, the locking mechanism is controlled to release the pad and make the pad overlap the rear end of the truck bed. Then the flipping plate is overlapped on the pad. The flipping plate and the pad are indirectly connected to the unloading platform body, which can maintain the stability of the two after they overlap. When the workers load and unload goods, the flipping plate and the pad are not easy to slip, which is conducive to the workers loading and unloading goods.

[0028] 2. By incorporating a housing, cover plate, movable plate, locking rod, and spring, the spring ensures that the locking rod is stably engaged with the gear. When it is necessary to release the pad, simply pull the end of the locking rod away from the gear. The overall structure of the locking device is simple, allowing for short-term restraint of the pad while facilitating operation by staff. By engaging the locking rod at different positions on the gear, the rotation angle of the pad can be selected according to actual usage, thus facilitating the stable placement of the pad on the truck.

[0029] 3. By setting up a fixing ring, pull rope, guide ring, and pull ring, it is convenient for the operator to release the locking rod and gear connection while rotating the pad, thus facilitating the operator's operation. Attached Figure Description
