Method for transferring materials through loading hopper system

Abstract

The invention discloses a method for transferring materials through a loading hopper system. The method adopts a loading hopper system to transfer materials, and comprises the following specific steps: a vehicle identification subsystem reads information of a transfer vehicle and sends the information to a field PLC (Programmable Logic Controller); the PLC collects vehicle information in real time; the materials are unloaded into the hopper, and a transfer vehicle is poured below the discharging opening; the PLC controls the bin door to be opened, and charging is started; the PLC controls the bin door according to the height requirements of the material full area of different transfer vehicles, and materials are continuously loaded to the transfer vehicles for several times; when the material level sensor detects that the current material level height is in the height of a full material area, the PLC controls the bin door to be closed, a driver drives away from the position below the discharging opening of the discharging hopper, and the loading process is completed. Due to the fact that the frame is provided with the connecting arm connected with the portal crane, the walking wheels arranged at the lower end of the frame can move on the portal crane rail and share the rail with the portal crane, and an operation site and a storage site are not occupied. Man-machine interaction is realized, and misoperation is reduced.

Description

technical field [0001] The invention relates to the technical field of methods and equipment for loading and unloading transshipment goods at wharves and the like, in particular to a loading hopper and a method for transshipment materials. Background technique [0002] Generally, bulk bulk materials such as sand, fertilizer, ore, cement, coal, etc. are transported by ships with a large carrying capacity, which are loaded into the cabin first, and transported to ports on land via long-distance oceans. The above-mentioned materials are loaded and unloaded on the large-scale bulk cargo transport vehicle (hereinafter referred to as the transfer vehicle) by the advanced loading and unloading equipment, and then the materials are transported to the production plant by inland transportation as raw materials for production, or the goods are temporarily stored in the yard for transshipment . In order to shorten the time of ships in port and save shipping schedules, improving the eff...

AI Technical Summary

Problems solved by technology

When the transfer hopper is used, it needs to occupy the work site, and when it is not in use, it needs to be transported to a special site at the front of the dock for storage

[0004] 2. Poor maneuverability, low loading efficiency and high cost of use

[0005] 3. Accurate loading cannot be achieved

Whether the existing transfer hopper (or hopper) is an open hopper, a manual control, or an automatic control hopper, the standard is basically to fill the vehicle with no overflow, and it cannot achieve accurate measurement

[0006] 4. Poor security

During the loading process of the transfer vehicle, the vehicle is located directly below the hopper, and the grab bucket of the door machine operates directly above the vehicle, and there are safety hazards such as overflow and buried vehicle

[0007] 5. Frequent handling of hoppers leads to high failure rate

[0008] 6. The on-site loading process and loading situation cannot be monitored remotely, the on-site emergency response is not fast enough, and on-site emergency stop processing is dangerous
