Description

Intelligent loading hopper and method for transferring materials

technical field

The invention relates to the technical field of methods and equipment for loading and unloading transshipment goods at docks and the like, in particular to a loading hopper and a method for transshipping materials.

Background technique

In general, the transportation methods of bulk bulk materials such as sand and gravel, fertilizer, ore, cement, coal, etc. are mostly carried by ships with a large carrying capacity into the cabin first, and then transported to the port set on land by long-distance ocean, using the port The loading and unloading equipment will load and unload the above-mentioned materials onto large bulk cargo transport vehicles (hereinafter referred to as transfer vehicles), and then change the inland transport method to transport the materials to the production plant as production raw materials, or temporarily store the goods in the yard for transfer. . In order to compress the time of the ship in port and save the sailing period, improving the loading and unloading efficiency of the ship is the core factor, and the loading and unloading efficiency of the ship is also one of the main indicators to measure the competitiveness of the port. The usual unloading operation is to use the gantry crane on the wharf to realize the transfer of materials through the process of ship---gantry crane---transfer hopper---transfer vehicle---cargo yard. The existing loading hopper It is just a mechanical device, or lacks automation and intelligent control system, or the degree of automation is not high, and the degree of automation, loading and unloading efficiency and loading and unloading accuracy need to be improved. The existing loading hoppers mainly have the following problems:

1. Occupy the site. When the transfer hopper is used, it needs to occupy the operation site, and when not in use, it needs to be transported to a special site at the front of the wharf for storage.

2. Poor mobility, low loading efficiency and high use cost. When the door machine needs to be moved, the transfer hopper needs to be de-energized to clear the material, and then moved with a large forklift.

3. Precise loading cannot be achieved. Whether the existing transfer hopper (or hopper) is an open hopper, manual control, or automatic control hopper, basically, the standard is to fill the vehicle without overflowing, and it cannot achieve accurate measurement.

4. Poor security. During the loading process of the transfer vehicle, the vehicle is located directly under the hopper, and the gantry grab works directly above the vehicle, so there are potential safety hazards such as overflowing and burying the vehicle.

5. Frequent handling of hoppers leads to a high failure rate.

6. The on-site loading process and loading situation cannot be remotely monitored, the on-site emergency response is not fast enough, and the on-site emergency stop processing is dangerous.
