Description

Technical Field

[0001] The utility model relates to a container platform, in particular to a container loading and unloading platform. Background Art

[0002] In the field of bulk material loading into containers, when filling the containers, the containers need to be laid flat and the materials are filled into the containers using a conveyor. The disadvantage of this process is that the bulk material cannot be fully filled into the container, which seriously wastes transportation resources.

After the locks are aligned, the box locking operation needs to be performed manually. Therefore, using this platform to load and unload containers is time-consuming and labor-intensive, and it is dangerous for the operator. Summary of the invention

[0062] The following is combined with Figure 2-6 , the working process of the utility model is explained.

[0063] The vehicle carrying the container drives under the rotary spreader 1. The longitudinal adjustment hydraulic cylinder 13 and the fine adjustment hydraulic cylinder 10 are operated to align the latches 9 at the four corners of the rotary spreader 1 with the lock holes at the four corners of the container.

[0064] The lifting hydraulic cylinder 6 and the tilting hydraulic cylinder 2 are operated to lower the rotating spreader 1 until it completely falls on the container. At this time, the latch 9 has been inserted into the lock hole.

[0065] The latch hydraulic cylinder 8 is operated to lock the latch 9.

[0066] The lifting hydraulic cylinder 6 and the tilting hydraulic cylinder 2 are operated to lift the container and detach it from the vehicle.

[0067] The vehicle drives out of the rotating lifting device 1 .

[0068] Operate the lifting hydraulic cylinder 6 and the flipping hydraulic cylinder 2 to descend to the lowest position to open the container door. Then operate the flipping hydraulic cylinder 2 to flip the rotary spreader 1 (when loading, the container door faces upward; when unloading, the container door faces downward).

[0069] Taking loading as an example, after loading is completed, the hydraulic cylinder 14 for closing the container door is operated to retract the arm 15 and close the container door. Then, the hydraulic cylinder 2 for turning over is operated to be lowered, and the lifting hydraulic cylinder 6 and the hydraulic cylinder 2 for turning over are operated to be raised at the same time, so that the container is kept horizontal and the bottom of the container is about 20 cm higher than the loading surface of the vehicle (such as a trailer) (after unloading, the hydraulic cylinder 2 for turning over is lowered first, and then the container door is closed).

[0070] The vehicle drives under the container, and the longitudinal adjustment hydraulic cylinder 13 and the fine adjustment hydraulic cylinder 10 on the rotary spreader 1 are operated to align the container with the loading surface of the vehicle. The lifting hydraulic cylinder 6 and the flipping hydraulic cylinder 2 are lowered to place the container on the loading surface of the vehicle. The locking hydraulic cylinder 8 is operated to unlock and the rotary spreader 1 is raised. The vehicle drives away. One operation is completed.

[0071] It should be noted that the control method for the hydraulic cylinder mentioned in the present invention can adopt a common hydraulic cylinder control method, which will not be described in detail here to ensure the brevity of the specification.

[0072] By using the container loading and unloading platform provided by the utility model, the following beneficial effects can be achieved:

[0073] The container loading and unloading platform provided by the utility model adjusts the position of grabbing the container by rotating the lifting device, and does not need the container truck to move to cooperate with the grabbing operation, and the grabbing speed is fast. The container can be quickly locked on the container through the hydraulic locking mechanism, and there is no need to manually lock the container, which reduces the risk of the container falling and protects the safety of the operator to the greatest extent.
