Technical Field
[0001] This utility model belongs to the technical field of ore feeding equipment, specifically relating to an automatic feeding system for an energy storage power supply belt conveyor ore feeding car. Background Technology
[0002] Belt conveyor ore distribution cars are widely used in large-scale mining and beneficiation processes, and their operation is generally carried out manually on-site. Their structure consists of: a traveling wheel, drive rollers, idlers, a frame, two motors and a reducer, and two brakes. The two motors of the belt conveyor ore distribution car are generally powered by the same set of sliding wire power lines, making it impossible to monitor the operation of a single motor. The following problems frequently occur during production: 1. During power supply, the current collector often jumps as it slides along the marking line, causing momentary single-phase fluctuations that impact the motor and reduce its lifespan; 2. Inaccurate positioning of the ore distribution car leads to ore spillage; 3. Brake failure causing single-motor operation cannot be detected in time, resulting in single-motor burnout, and in severe cases, both motors burn out simultaneously; 4. Long fault inspection time and a tendency to misdiagnose; 5. Single-motor failure in the ore distribution car causes impact on the track, resulting in track deformation and breakage, as well as broken traveling wheel axles and motor damage. This leads to excessively long maintenance times, increasing the labor intensity of the operators, causing unreasonable consumption of spare parts, and directly affecting stable production operation. Therefore, it is very important to solve the problems of automatic material placement and remote monitoring of unloading vehicles. Utility Model Content

The system is characterized by further including an automatic material distribution system. The automatic material distribution system includes a real-time material level detection system for the ore bin, a real-time position detection system for the conveyor belt ore distribution car, an electrical control system, and an energy storage power supply system. The energy storage power supply system supplies power to the conveyor belt ore distribution car 1, including a charging coil 15, a collector 8, and an energy storage device 17. The charging coil 15 is installed on one side of the lower part of the track of the ore distribution car 1, and the energy storage device 17 is installed on the tail truss of the conveyor belt ore distribution car 1. There are two collectors 8, which are located outside the charging coil 15. The collectors 8 are fixedly connected to the energy storage device 17 and move with the conveyor belt ore distribution car. The two collectors 8 can ensure that one of them is placed inside the charging coil 15. The energy storage power supply system can realize continuous charging of the conveyor belt ore distribution car, avoid the problem of instantaneous single-phase and motor impact caused by the current collector jumping on the line, and extend the service life of the motor.
[0015] The real-time material level detection system in the ore bin is a material level sensor A13 installed on the upper part of the ore bin; The real-time position detection system for the conveyor belt ore distribution car includes magnetic rods 11 on both sides of the lower part 5 of the material distribution hopper, a material level detector B6, and a proximity switch 10 located directly above the crossbeam of each ore bin. The material level detector B6 is used to monitor the start of the conveyor belt ore distribution car 1 when the ore bin is filled to the rated amount.

The proximity switch 10 of this invention is installed directly above the crossbeam of the ore bin and interacts with the magnetic rods 11 installed at a relative position below the movable material distribution hopper 5 of the conveyor belt ore distribution car 1. When the magnetic rods 11 pass the proximity switch 10, the position of the conveyor belt ore distribution car 1 is displayed, realizing real-time monitoring of the position of the conveyor belt ore distribution car 1 and accurate positioning.
[0016] The electrical control system includes a control cabinet 2, an onboard PLC control system and a local PLC control system in the main control room, both located within the control cabinet 2. The control cabinet 2 is positioned on the side of the conveyor belt ore distribution car 1. The onboard PLC control system is connected to the level detector B6 and the drive motor 9 of the conveyor belt ore distribution car. The onboard PLC control system communicates with the host computer via a network bridge transmitter 3. It is used to transmit the collected information on the operating status of the drive motor 9 of the conveyor belt ore distribution car and the information from the level detector B6 back to the local PLC control system in the main control room.
[0017] The aforementioned bridge transmitter 3 is fixedly installed on the frame of the conveyor belt ore-laying car and on the belt frame corresponding to the frame of the conveyor belt ore-laying car, respectively, for communication connection between the on-board PLC control system and the control system in the main control room, so that it can communicate normally with the local PLC control system and avoid obstruction affecting its communication.
[0018] The local PLC control system in the main control room is also equipped with upper and lower limit alarm devices for material levels. When the collected data signal is abnormal, it is sent to the host computer via the network bridge transmitter 3 to issue an alarm. At the same time, the operator can monitor the operating status of the ore carrier 1 in real time through the information and impact displayed on the host computer screen. Based on the alarm display and impact information, the operator can determine the fault location, take corresponding measures, and notify maintenance personnel to handle the problem, thus shortening the fault inspection time and preventing misdiagnosis.
[0019] This utility model provides travel limit switches (not shown in the figure) at both ends of the mine storage platform 1 to limit the travel of the conveyor belt ore distribution car.
[0020] The energy storage device 17 is a battery, which is connected to the charging coil 15, the receiver 8 and the drive motor 9 of the belt conveyor mining car.
[0021] Both the material level detector B6 and the material level detector A13 are radar detectors.
[0022] The working principle of this utility model is as follows: The conveyor belt ore carrier 1 is powered by an energy storage power supply, and the steps are as follows: Step 1: After the vibration and temperature sensors 7 and the material level detector A13 collect the current, temperature of each part, vibration operation parameters, and material level and position information of the belt conveyor ore carrier's drive motor 9, the unloading target ore carrier is determined based on the ore carrier's running position and the ore carrier's material level. The data is then transmitted to the on-board PLC control system and transmitted to the local PLC control system via the wireless bridge 3; thus realizing real-time monitoring of the ore carrier's position and operation status. Step 2: After receiving the ore bin level information and the belt conveyor ore carrier position information data, the local PLC control system analyzes the data and uploads the analysis results to the host computer. The host computer provides a user interface and displays feedback data, and sends operation instructions to the local PLC control system. The operator remotely and manually operates the mouse to select the target ore bin for feeding and operates the "unload" button on the human-machine interface to unload and feed ore into the selected ore bin. When the ore bin level exceeds the set threshold, the host computer operation interface will issue an alarm prompt, and the host computer will issue an operation instruction to stop feeding and remind the operator to perform a bin transfer operation. Step 3: When all ore bins are unloading close to the average level and the ore bins reach a high material level of over 80%, replenishment and material placement are carried out. This is done by clicking the "Replenish" button on the human-machine interface with a mouse. At this time, the conveyor belt ore placement car will carry out patrol and material placement. When the replenishment material level reaches the set threshold, the host computer will issue an operation command, and the on-board PLC will control the conveyor belt ore placement car to go to the next ore bin in sequence to replenish material until all ore bins have been replenished.
