Description

Technical Field

[0001] The present invention relates to the technical field of dock equipment, and more specifically, to an intelligent commercial settlement ship unloader device. In addition, the present invention also relates to a method for using the intelligent commercial settlement ship unloader device. Background Art

[0002] Bulk materials such as ore, coal, and grain are important raw materials for national economic production, accounting for more than 50% of port cargo volume. In the process of loading and unloading bulk cargo at ports, commercial measurement is the key to the settlement of bulk cargo terminal business, and is also the core of the interests of buyers, sellers, and terminals. Therefore, how to achieve efficient and accurate weighing and measurement of bulk cargo without affecting the loading and unloading efficiency of port equipment has always been a key issue for port enterprises.

[0003] Measurement is the core key to the settlement of bulk cargo terminal business, and is the key to the interests of buyers, sellers, and terminals. Bulk cargo water transportation uses the water gauge as the basis for settlement, and implements shipment measurement and settlement. The water gauge measurement error is large. After several transfers, the actual arrival is less than the waybill, and the cargo owner suffers losses. Whether the arrival measurement can be achieved has always been the hope of the cargo owner, but the port terminal has not had a truly legal measurement equipment to achieve arrival measurement. Electronic belt scales are continuous dynamic measurements. In actual use, due to the large zero drift after calibration, they cannot be used as a basis for business settlement. In direct transshipment operations, since it is difficult to arrange electronic belt scales on the direct transshipment process line at the terminal, and the company's direct transshipment business accounts for nearly 40%, how to solve the precise measurement of direct transshipment is an actual demand faced by the company.

[0004] At present, the most commonly used method is: in order to protect the interests of the three parties, arrange professionals to observe the water gauge and take photos for record. After the unloader is unloaded, send personnel to observe the water gauge and take photos for record, so as to make business settlement. This method has the highest accuracy of the ship water gauge measurement method of about 0.5%, but its measurement accuracy is easily affected by many factors such as wind and waves, water density around the ship and changes in the ship itself. It is also related to the professional quality of the surveyors. Therefore, the measurement stability cannot be guaranteed, which increases the difficulty of weight measurement of cargo at the terminal.

[0005] In summary, how to provide a grab ship unloader that can increase metering accuracy and has an automatic calibration function is a problem that currently needs to be solved urgently by those skilled in the art. Summary of the invention

DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] The core of the present invention is to provide an intelligent commercial settlement ship unloader device, which can greatly improve the accuracy of cargo measurement at the dock.

[0055] Another core of the present invention is to provide a method for using the above-mentioned intelligent commercial settlement ship unloader device.

[0056] Please refer to Figure 1-Figure 5A smart commercial settlement ship unloader device includes a frame 1, a weighing sensor 4, a compensating weighing sensor 5 and a weight verification assembly 6. A weighing hopper 2 is provided on the frame 1. A plurality of discharge ports are provided at the bottom of the weighing hopper 2. A discharge gate 3 for opening and closing the discharge port is installed at the discharge port. The weighing sensor 4 is installed on the frame 1 and is used to weigh the weighing hopper 2. The weighing hopper 2 is connected to the weighing sensor 4. The compensating weighing sensor 5 is used to calculate and compensate the weighing data of the weighing sensor 4. The weight verification assembly 6 includes a plurality of verification weights 601 and a lifting member 602. The plurality of verification weights 601 can be detachably installed on the weighing hopper 2 to provide counterweight for the verification of the weighing hopper 2. The lifting member 602 is installed on the weighing hopper 2. The lifting member 602 is used to install the verification weights 601 on the weighing hopper 2.

[0057] When in use, the weighing sensor 4 is installed on the frame 1, and the weighing hopper 2 is connected to the weighing sensor 4, that is, the weighing sensor 4 is used to weigh the weighing hopper 2, and a plurality of discharge ports are provided at the bottom of the weighing hopper 2, and a discharge gate 3 for opening and closing the discharge port is installed at the discharge port, that is, the material in the weighing hopper 2 is released through the discharge gate 3, and the compensating weighing sensor 5 is used to calculate and compensate the weighing data of the weighing sensor 4. Through the data compensation of the compensating weighing sensor 5, the accuracy of the weighing data of the weighing sensor 4 in the weighing process is improved, and the weighing data under the interference of low-frequency vibration is corrected in real time, which greatly improves the weighing accuracy in the low-frequency vibration environment, which is conducive to the efficient and accurate weighing of bulk materials. In commercial measurement, the weight calibration assembly 6 includes a plurality of calibration weights 601 and a lifting member 602. The plurality of calibration weights 601 are detachably mounted on the weighing hopper 2 to provide counterweight for calibration of the weighing hopper 2. The lifting member 602 is mounted on the weighing hopper 2. The lifting member 602 is used to install the calibration weights 601 on the weighing hopper 2. That is to say, through the cooperation of the lifting member 602 and the calibration weights 601, when the weighing hopper 2 needs to be calibrated, the lifting member 602 is started to automatically install the calibration weights 601 on the weighing hopper 2. By adding the standard counterweight, the calibration of the weighing hopper 2 is achieved, and the automatic hanging and lowering of the calibration weights 601 can be achieved, thereby improving the convenience of calibration and the accuracy of the weighing hopper 2.

[0058] It should be noted that the accuracy level of the calibration weights in the embodiment of the present invention is M12 (the maximum allowable error range is ±0.01%), the single weight is 1 ton, and the calibration adopts half-code calibration or full-code calibration. The intelligent hanging weight calibration device automatically sends a signal after detecting that the accuracy of the metering system does not meet the set requirements. The equipment stops and automatically lifts the standard weight to perform static self-inspection and calibration on the metering system. At the same time, the intelligent hanging weight calibration device can also be used to calibrate the metering system regularly.

[0059] In addition, in the above-mentioned embodiment, the data-based automatic sensor calibration method is used to analyze the sensor data to obtain its error data, and automatic calibration is achieved through data processing. During the metering operation of the ship unloader equipment, the data collected by the main and auxiliary sensors are analyzed and their error characteristics are obtained. Automatically analyze whether the error comes from the impact of increased unloading materials. The system automatically calculates that the data is increasing significantly and steadily. Combined with the grab bucket discharge action, it means that the system is working normally at this time. When the system waits for the stabilization time and the recognition error is still large, the metering system automatically stops working and automatically lifts the 16T weight, automatically detects and analyzes whether the data collected by the sensor increases by 16T, and automatically calibrates the sensor with the data.

[0060] Optionally, in some embodiments, the weighing sensor 4 is a twisted ring weighing sensor 4 , and the number of the weighing sensors 4 is at least 4 and they are evenly distributed around the weighing sensor 4 .

[0061] Optionally, in some embodiments, the number of compensating weighing sensors 5 is the same as the number of weighing sensors 4, and based on the dual-scale comparison and compensation dynamic weighing method, four torsion ring weighing sensors 4 are corrected and controlled in real time using four compensation measurement unit signals to achieve accurate weighing of bulk materials in a low-frequency vibration environment.

[0062] In some embodiments, a standard weight is provided on the compensating weighing sensor 5, and the weight of the material in the weighing hopper 2 is obtained by calculation. , and its calculation formula is:

[0063] ;

[0064] Among them, Mg is the real weight of the material, W1 is the weighing of the material, w0 is the static weight of the compensation weight, w is the weighing of the compensation weight, and M0 is the tare weight of the weighing hopper 2. That is to say, through the above formula calculation, the compensation weighing sensor 5 can compensate the data of the weighing sensor 4 to achieve accurate weighing of bulk materials in a low-frequency vibration environment.

[0065] It should be noted that in the embodiment of the present invention, since the deformation of the weighing hopper 2 and the compensating weighing sensor 5 under the rated weight is less than 0.2 mm, the natural frequency of the weighing system can be approximately expressed as: ;

[0066] At the same time, according to the single degree of freedom vibration theory, when the foundation vibrates at a frequency f, the ratio of the acceleration of the object in the silo or the object on the reference scale to the foundation vibration acceleration is approximately:

[0067] ;

[0068] Where g is the acceleration due to gravity, is the rated deformation of the weighing system sensor, is the damping coefficient; , when the basic vibration frequency is low, α ≈1; when the overall stiffness of the weighing hopper 2 is large enough, the acceleration of the weighing hopper 2 and the material inside it is consistent with the acceleration of the compensating weighing device. The compensating weighing device is used to compensate and correct the data measured by the weighing scale, thereby achieving accurate measurement of the material and effectively solving the measurement problem in a low-frequency vibration environment.

[0069] Please refer to Figure 1-Figure 5 In some embodiments, the weight verification assembly 6 also includes a connecting rope 603, one end of the connecting rope 603 is connected to the verification weight 601, and the other end of the connecting rope 603 is connected to the lifting member 602. That is to say, the verification weight 601 is connected to the lifting member 602 through the connecting rope 603, so that the lifting member 602 can quickly drive the verification weight 601 to a certain height, and the lifting member 602 is installed on the weighing hopper 2. Therefore, when the verification weight 601 is lifted to a certain height from the frame 1, it is connected to the weighing hopper 2 to achieve the application of calibration weight to the weighing hopper 2. When the calibration is completed, the lifting member 602 lowers the verification weight 601 and places it on the frame 1, so that the weight of the verification weight 601 is unloaded from the weighing hopper 2, thereby realizing the automatic hanging of the verification weight 601, which is more convenient and has higher calibration efficiency.

[0070] Optionally, in some embodiments, the lifting member 602 may adopt a telescopic structure such as an electric cylinder or a pneumatic cylinder. Specifically, the electric cylinder is installed on the weighing hopper 2, and the end of the connecting rope 603 is connected to the protruding end of the electric cylinder, so that when the electric cylinder is extended or retracted, the weight can be hung and lowered.

[0071] In other embodiments, the weight calibration assembly 6 also includes a roller 604, which is rotatably installed on the weighing hopper 2, one end of the connecting rope 603 is wrapped around the roller 604, and the lifting member 602 uses a motor to control the rotation of the roller 604. That is to say, the rotation of the motor is used to drive the roller 604 to rotate, so that the roller 604 stirs and wraps around the connecting rope 603, thereby achieving the purpose of hanging the weight and removing the weight to reverse the control motor.

[0072] Optionally, in some embodiments, a reducer is provided at the output end of the motor, and the torque at the output end of the motor is increased by the reducer.

[0073] Please refer to Figure 1-Figure 5In order to improve the closing effect of the gate, in some embodiments, the cross-section of the discharge gate 3 is arc-shaped, and there are two discharge gates 3. The two discharge gates 3 are closed in an up-and-down staggered manner, that is, the two discharge gates 3 are both arc-shaped. When the two discharge gates 3 are closed, they are closed in an up-and-down stacked staggered manner, which can effectively avoid the arc gates from sticking and clamping materials, and the up-and-down staggered manner can prevent leakage.

[0074] It should be noted that, in the embodiment of the present invention, the overlapping parts of the two discharge gates 3 maintain close contact when closed.

[0075] Please continue to refer to Figure 1-Figure 5 In some embodiments, two main shafts 7 are provided on the weighing hopper 2, and the discharge gate 3 is rotatably installed on the main shaft 7. Partial gears that mesh with each other are provided on the two discharge gates 3, and the partial gears are coaxially arranged with the main shaft 7. That is to say, partial gears that mesh with each other are provided on the two discharge gates 3, and the two discharge gates 3 rotate synchronously with each other through the partial gears. Therefore, only one of the discharge gates 3 needs to be controlled, and the two discharge gates 3 that rotate relative to each other can further reduce the situation of material clamping.

[0076] Optionally, in some embodiments, the opening and closing of the discharge gate 3 is controlled by an electric cylinder or a pneumatic cylinder. Specifically, the electric cylinder is hinged to the weighing hopper 2 , and the protruding end is hinged to the discharge gate 3 .

[0077] Please refer to Figure 1-Figure 5 In order to further improve the weighing accuracy of the weighing sensor 4, in some embodiments, a damping member 8 is also included. The damping member 8 is installed between the weighing sensor 4 and the frame 1, and is used to reduce the impact when the hopper receives the material. That is to say, a damping member 8 is added between the weighing sensor 4 and the frame 1 to reduce the impact when the hopper receives the material, thereby improving the accuracy of the weighing quantity.

[0078] Optionally, in some embodiments, the damping member 8 adopts a two-stage hydraulic damping device.

[0079] At the same time, in order to reduce the impact of materials on the sensor during discharging and speed up the stabilization speed of the sensor signal, a "hydraulic double-stage damping device" is added under the weighing sensor 4 to provide buffering at the beginning of discharging and damping at the end of discharging, which can reduce the impact of materials on the sensor and speed up the attenuation of the sensor vibration signal, which is more conducive to the dynamic measurement of the hopper.

[0080] Optionally, in some embodiments, the hydraulic pressure of the dual-stage hydraulic damping device is 14 MPa.

[0081] From the output waveform of the test sensor, it can be concluded that when the "hydraulic two-stage damping device" function is not added, there is a large impact load in the process of discharging the grab hopper, and the attenuation of overshoot is also slow; when the hydraulic two-stage damping function is activated with 20 MPa oil pressure, the impact load of the process of discharging the grab hopper is reduced, and the attenuation of overshoot is also accelerated; when the damping function of 14 MPa oil pressure is used, the impact load of the process of discharging the grab hopper is further reduced, and the attenuation of overshoot is also faster. Therefore, the system should be equipped with a "hydraulic two-stage damping device" with a hydraulic pressure of about 14 MPa.

[0082] Please refer to Figure 1-Figure 5 In some embodiments, it also includes a receiving plate 6, which is installed on the weighing hopper 2 and is used to receive the leaked material in the direction of the grab bucket, reduce the leakage of the grab bucket, and reduce material loss.

[0083] Optionally, in some embodiments, the receiving plate 6 is hinged to the weighing hopper 2, and a driving member 10 is installed on the weighing hopper 2. The driving member 10 is used to control the rotation angle of the receiving plate 6. That is to say, the rotation angle of the receiving plate 6 is controlled by the driving member 10. When receiving materials, the receiving plate 6 is horizontal. After unloading is completed, the receiving plate 6 rotates upward to allow the received materials to enter the weighing hopper 2, which is conducive to further reducing the weighing error.

[0084] Please refer to Figure 1-Figure 5 In some embodiments, it also includes a discharge hopper 11 and a distribution hopper 9. The discharge hopper 11 is installed on the frame 1 and is located below the weighing hopper 2. It is used to receive the material discharged from the weighing hopper 2. The distribution hopper 9 is installed on the frame 1. The distribution hopper 9 is used to receive the material under the discharge hopper 11 and divert the material. The distribution hopper 9 is used to evenly distribute the material to each belt.

[0085] Please refer to Figure 6 , a method for using an intelligent commercial settlement ship unloader device, comprising:

[0086] S1) sending a signal to the lifting member 602, and the lifting member 602 installs the calibration weight 601 on the weighing hopper 2 to complete the calibration of the weighing hopper 2;

[0087] S2) Detect whether the discharge gate 3 of the weighing hopper 2 is closed;

[0088] S3) The commercial metering system is put into use and the code list is cleared;

[0089] S4) The hopper grabs the material and moves to the top of the weighing hopper 2;

[0090] S5) When the weighing sensor 4 measures that the weight of the weighing hopper 2 is less than 1T, the commercial metering system allows the grab bucket to discharge the material;

[0091] S6) The weighing sensor 4 weighs the weighing hopper 2 and sends a weighing data signal to the commercial metering system, and the commercial metering system accumulates the weighing data;

[0092] S7) When the whole ship is detected to be unloaded, the commercial metering system automatically generates the cumulative metering data of the code list;

[0093] S8) Automatically print the settlement code slip.

[0094] The above method can realize automatic weighing and statistics of materials, which is beneficial to improving the automation of ship unloading.

[0095] A smart terminal data control center is also established, and all data are sent to the terminal big data service center. First, after the data control center issues a metering mode input signal command, the ship unloader driver starts normal unloading operations. The ship unloader metering control center automatically records all data and transmits real-time data to big data, and the background automatically records all current data. When the ship unloader has unloaded the ship, the service center sends a signal to stop the ship unloader, the metering control center automatically settles the metering data of the ship, and the big data service center automatically receives the metering data. If the big data center fails, the ship unloader equipment retains all the original metering data. All automatically generated settlement code sheets are compared with the original data.
