Description

Technical Field

[0001] This utility model relates to an auxiliary device for unloading parcels in express delivery, belonging to the field of logistics transportation technology. Background Technology

[0002] Express delivery, also known as courier or freight, refers to a new mode of transportation in which logistics companies quickly and safely deliver documents or packages entrusted by users from the sender to the recipient. When express parcels are transported to the transfer station, they need to be unloaded from the transfer vehicle, re-counted, and then reloaded.

[0003] For example, utility model patent CN222512224U discloses an auxiliary device for unloading parcels in express delivery. The device includes a vehicle body with hydraulic chucks on both sides and an unloading plate on top. The bottom of the unloading plate is movably connected to the top of the vehicle body via a pivot. A buffer device is located at the rear of the unloading plate, and a worm gear screw device is located at the front of the pivot. This utility model uses casters under the vehicle body to allow employees to quickly move the device to the desired position. During unloading, employees only need to place the parcel on top of the unloading plate, and the parcel will slide down automatically, significantly reducing the labor intensity of employees. The unloading height of the unloading plate can be adjusted via the worm gear screw device at the bottom. The parcel slides down the unloading plate to the bottom and collides with the buffer device, thus mitigating the impact and protecting the parcel. Furthermore, the spring force can be adjusted to handle parcels of different weights and sizes.

[0004] However, the above solution has the following shortcomings in practical use:

[0005] 1. After the express delivery item slides down the unloading plate onto the buffer plate of the buffer device, it still needs to be picked up manually. If the manual picking is too slow, it may cause subsequent express delivery items to collide with the express delivery items on the buffer plate, resulting in secondary impact damage.

[0006] Second, in addition, express parcels are generally transported by truck. When they arrive at the parcel depot, operators need to remove the parcels from the truck's cargo box. The aforementioned device can only be placed at the door of the cargo box and cannot go deep into the cargo box. After the parcels at the cargo box door are removed, operators need to retrieve the parcels deep inside the cargo box. Since the aforementioned device lacks a transport structure, it is necessary to manually move or push the parcels onto the aforementioned device. This manual operation is extensive and time-consuming. Summary of the Invention

[0007] To solve the above-mentioned technical problems, this utility model provides a parcel unloading auxiliary device for express delivery, which enables the parcels that slide down the unloading plate onto the buffer device to be quickly removed, avoiding the impact on the buffer protection of subsequent parcels caused by untimely manual handling of parcels. At the same time, a detachable transport frame structure is added, which allows for easy and labor-saving manual pushing of large parcels onto the unloading plate by extending the transport frame into the cargo compartment.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A parcel unloading auxiliary device for express delivery includes: a mobile frame with an unloading plate mounted on it; one end of the unloading plate being rotatably connected to the mobile frame via a hinged bracket; a lifting mechanism mounted on the top wall of the mobile frame, the lifting mechanism abutting against the bottom wall of the unloading plate; a buffer mechanism mounted on the top wall of one end of the unloading plate; a buffer seat movably connected to the side wall of the buffer mechanism; a toggle mechanism movably mounted on the side wall of the buffer seat away from the buffer mechanism; and an extended conveyor frame detachably fixedly mounted on the end of the unloading plate and located away from the bottom wall. On one side of the buffer mechanism, the extended conveyor frame and the unloading plate are rotatably connected. In this scheme, when the unloading plate is placed at an angle, the express parcel can be manually slid down the inclined surface of the unloading plate. The buffer mechanism on the unloading plate cushions the impact of the falling parcel. The express parcel sliding down the unloading plate will fall into the buffer seat. The forward and reverse rotation of the motor output controls the clockwise / counterclockwise rotation of the drive screw fixed to it, thereby driving the push plate to move back and forth along the moving groove, quickly pushing the express parcel that has fallen into the buffer seat away from the unloading plate, avoiding the accumulation of express parcels and affecting subsequent buffer protection.

[0010] In addition, after the express parcels at the cargo box door are emptied, the staff needs to go inside the cargo box to retrieve the express parcels located deep inside. At this time, the extended conveyor frame can be taken out from the mobile frame and assembled at the end of the unloading plate, so that the extended conveyor frame is placed on the bottom wall of the cargo box. The staff can transport large express parcels on the extended conveyor frame. When large express parcels are moved, the rotation of the conveyor rollers can reduce the amount of manual lifting work, and also reduce the frictional resistance when large express parcels are dragged by hand.

[0011] Preferably, the actuating mechanism includes: a movable groove is formed on the side wall of the buffer seat away from the buffer mechanism; a drive screw is rotatably connected in the movable groove; a motor is fixedly connected to the side wall of the buffer seat; the output end of the motor is fixedly connected to the end of the drive screw; a disengaging plate is also slidably connected in the movable groove; the disengaging plate is threadedly connected to the drive screw. In this scheme, when the express package slides onto the buffer seat along the inclined unloading plate, the output end of the motor controls the drive screw fixedly connected to it to rotate. The drive screw drives the disengaging plate to move horizontally in the movable groove. By rotating the motor output end clockwise or counterclockwise, the drive screw is driven to rotate, thereby controlling the disengaging plate to move back and forth along the movable groove, disengaging the express packages piled on the buffer seat, so that the express packages are removed from the unloading plate.

[0012] Preferably, a buffer sponge pad is also provided on the side wall of the buffer seat away from the buffer mechanism, and the buffer sponge pad is arranged around the periphery of the moving groove; in this solution, by providing a buffer sponge pad, the buffer mechanism can be used to protect the express package and reduce the impact when it slides down the inclined unloading plate.

[0013] Preferably, the extended conveyor frame includes: a rectangular frame with a rectangular groove formed inside the rectangular frame, multiple conveying rollers rotatably connected inside the rectangular groove, the multiple conveying rollers being distributed sequentially at equal intervals inside the rectangular groove, support shafts fixedly installed on both side walls of one end of the rectangular frame, two support shafts being symmetrically arranged, and a groove being opened on the end of the unloading plate away from the buffer mechanism, with through holes opened on both inner walls of the groove, the support shafts passing through the corresponding through holes and rotatably connected to the through holes; In this solution, when the express parcels at the cargo box door are emptied, manual unloading of express parcels deep inside the cargo box is required. At this time, in order to reduce the workload of manual lifting, the extended conveyor frame is assembled onto the end of the unloading plate and placed inside the cargo box. The extended conveyor frame is placed inside the cargo box, and the manual labor can place the express parcels deep inside the cargo box on the extended conveyor frame and transfer the express parcels by rotating the multiple conveying rollers, so that they move to the unloading plate quickly and stably, reducing the workload of manual lifting.

[0014] Preferably, the through hole connects the inner wall of the groove to the outer wall of the unloading plate, and the end of the support shaft away from the rectangular frame passes through the through hole and extends to the outer side of the unloading plate. The end of the support shaft away from the rectangular frame has a locking hole, a locking bolt passes through the locking hole, and a locking nut is threaded onto the threaded end of the locking bolt. In this scheme, on the fixed extended conveyor frame, one end of the frame with two support shafts faces the unloading plate, and then the two support shafts are inserted into the two through holes on the inner wall of the groove. Then, the support shafts pass through the through holes. At the end of the support shaft that passes through the through hole, the threaded end of the locking bolt is manually passed through the locking hole, and a locking nut is threaded onto the threaded end that passes through the locking hole, thereby achieving locking and limiting of the support shaft, and thus ensuring the stability of the extended conveyor frame during assembly.

[0015] Preferably, the side wall of the mobile frame is provided with a placement slot, and the extended conveyor frame is housed in the placement slot; in this solution, by setting the placement slot, unused extended conveyor frames and spare parts can be stored, avoiding the loss of extended conveyor frames and spare parts, and also facilitating quick manual retrieval and assembly later.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. When the unloading platform is tilted, the express parcels can be manually slid down the tilted surface of the unloading platform. The buffer mechanism on the unloading platform cushions the impact of the parcels falling. The parcels sliding down the unloading platform will fall into the buffer seat. The forward and reverse rotation of the motor output controls the clockwise / counterclockwise rotation of the drive screw fixed to it, thereby driving the push plate to move back and forth along the moving groove, quickly pushing the parcels that have fallen into the buffer seat away from the unloading platform, avoiding the accumulation of parcels and affecting subsequent cushioning protection.

[0018] In this device, after the express parcels at the cargo compartment door are emptied, a person needs to go inside the cargo compartment to retrieve the express parcels located deep inside. At this time, the extended conveyor frame can be taken out from the mobile frame and assembled at the end of the unloading plate, so that the extended conveyor frame is placed on the bottom wall inside the cargo compartment. The person can transport large express parcels on the extended conveyor frame. When large express parcels are moved, the rotation of the conveyor rollers can reduce the amount of manual lifting work, and also reduce the frictional resistance when large express parcels are dragged by hand.
