Description

Technical Field

[0001] This invention belongs to the technical field of bulk material loading, unloading and conveying equipment, and in particular relates to a semi-gantry scraper reclaimer with precise metering function. Background Technology

[0002] In the wave of transformation towards unmanned and intelligent operations in the bulk material handling field, unmanned stockpile intelligent control systems have become a core technological direction for improving bulk material management efficiency and reducing operating costs. Through the collaborative linkage of the data center management layer, network transmission layer, and equipment execution layer, they achieve fully automated scheduling and control of the entire stockpile operation process. As a key execution device connecting bulk material storage and transfer within this system, the semi-gantry scraper reclaimer is widely used in bulk material stockpiles for ore, coal, and grain. Its core function is to scrape bulk materials from the stockpile to the discharge port using a scraper device, directly unloading them onto a ground discharge conveyor belt, and then transferring them to a designated location outside the stockpile via a conveyor system, forming a crucial link in the material flow of unmanned stockpiles.

[0003] However, with the increasing demands for material proportioning accuracy, energy consumption control, and production efficiency in industrial production, the contradiction between the limitations of conventional semi-gantry scraper reclaimers and the technical requirements of unmanned yard intelligent control systems is becoming increasingly prominent. The unmanned yard intelligent control system aims at "full-process data transparency, intelligent operation scheduling, and automated equipment linkage," relying on real-time data feedback from each executing device to construct a closed-loop logic of "perception-decision-scheduling." The extensive operation mode of conventional reclaimers is becoming a key bottleneck restricting the effectiveness of this system.

[0004] This contradiction is particularly pronounced in unmanned material handling yards in industries such as metallurgy, building materials, and chemicals, which rely on precise material proportioning. In these scenarios, the intelligent control system for unmanned material handling yards needs to automatically generate multi-material proportioning schemes based on production work orders and allocate the work tasks of each material handling equipment through scheduling instructions. However, deviations in material proportions can not only lead to substandard product performance and production accidents, but also cause the intelligent scheduling algorithm to fail. For example, in unmanned raw material handling yards in the metallurgical industry, fluctuations in the amount of iron ore handled will directly affect the stability of subsequent smelting processes. Excessive handling will result in material waste, and material shortages will lead to production interruptions, both of which undermine the core advantage of "efficient and continuous operation" of unmanned material handling yards. At the same time, in cost-sensitive scenarios, the inability of conventional equipment to quantify the amount of material handled will cause the cost control module of the intelligent control system for unmanned material handling yards to lack data support, making it difficult to achieve accurate calculation and optimization of material consumption.

[0005] From a system collaboration perspective, the compatibility defects of conventional semi-gantry scraper reclaimers with unmanned yard intelligent control systems are mainly reflected in two aspects: First, the lack of data perception capabilities prevents the real-time collection of core data such as instantaneous material handling volume and cumulative material handling volume. This causes the central scheduling unit of the unmanned yard intelligent control system to be like "blind men touching an elephant," unable to accurately judge the material handling progress and material consumption status, and unable to dynamically adjust the operation strategy based on the yard inventory. Second, the rigid execution response mechanism is problematic. Parameters such as scraper running speed and material handling depth are mostly fixed settings or rely on manual experience for adjustment, making it unable to receive and execute dynamic control instructions issued by the system, which completely contradicts the "equipment linkage automation" requirements of unmanned yards. This problem of "data gap + execution lag" makes the material handling process a "performance bottleneck" in the unmanned yard intelligent control system, unable to meet strict material ratio requirements, and potentially disrupting the entire yard's operation rhythm due to unstable material supply.

[0041] The operating principle of the present invention is described as follows: The swing end beam 2 and the scraper material collection component 4 are connected by the hoisting component 6, which enables rapid adjustment of the conveying angle of the scraper material collection component 4. During the material conveying process, the material is first conveyed to the electronic belt scale 8 by the scraper material collection component 4 in conjunction with the guide chute component 7. The electronic belt scale 8 and the scraper material collection component 4 operate synchronously. The material is first unloaded onto the electronic belt scale 8. If it is within the metering range, it can be conveyed to the ground discharge belt conveyor to achieve precise material collection. It can realize real-time monitoring of the material collection amount, improve data accuracy, ensure precise material collection, and link with the control system. According to the set material collection amount, the running speed and scraper feeding depth of the scraper material collection component 4 are automatically adjusted to ensure stable material supply. By precisely controlling the material collection amount, waste caused by excessive material collection is avoided.

[0042] Each time a material weighing operation is completed, the electronic belt scale 8 feeds back the measurement information to the control system, and the control system controls the material viscosity detection mechanism 11 to operate once (the detection process is very fast and will not affect the material conveying). The electric push rod 113 pushes the viscosity detection rod 115 downward, so that the viscosity detection rod 115 detects the material viscosity. By detecting the material viscosity, the operating parameters of the equipment are optimized. For example, high-viscosity materials have poor flowability. If the scraper eats too deeply or the speed is too fast, the material is easily blocked at the feeding port, or even the scraper is damaged. Low-viscosity materials have good flowability, and the speed can be appropriately increased to improve efficiency. Through viscosity detection, the system can automatically adjust the scraper feeding depth (shallow for high viscosity, deep for low viscosity) and the operating speed (slow for high viscosity, fast for low viscosity), balancing efficiency and equipment safety.

[0043] Based on the material conveying volume fed back by the electronic belt scale 8 and the material viscosity fed back by the viscosity detection rod 115, the control system controls the cleaning reminder mechanism 13 to perform corresponding operations. Firstly, when the material viscosity reaches a set threshold, it indicates that the material viscosity is too high and it easily adheres to the electronic belt scale 8. Based on the material viscosity, the control system first controls the continuously variable transmission mechanism 14 to operate. When the material viscosity is higher, the control system controls the motor drive assembly 154 within the active adjustment mechanism 15 to rotate at a larger angle. The motor drive assembly 154 drives the first adjusting screw 152 and the second adjusting screw 153 to rotate synchronously. The threads on the walls of the first adjusting screw 152 and the second adjusting screw 153 are opposite threads. Through the interaction between the first adjusting screw 152 and the second adjusting screw 153 and the... The threaded connection of the first adjusting plate 155 and the second adjusting plate 156 causes the first adjusting plate 155 and the second adjusting plate 156 to drive the first sliding cylinder 146 and the second sliding cylinder 147 to move up and down respectively, thereby causing the movable disk 148 of the active cone wheel to move toward the fixed disk 144 of the active cone wheel, and causing the movable disk 149 of the driven cone wheel to move away from the fixed disk 145 of the driven cone wheel. Under the compression of the movable disk 148 of the active cone wheel and the fixed disk 144 of the active cone wheel, the working radius of the V-shaped steel belt drive belt 1410 at the corresponding position increases, while under the loosening of the movable disk 149 of the driven cone wheel and the fixed disk 145 of the driven cone wheel, the working radius of the V-shaped steel belt drive belt 1410 decreases, thereby increasing the transmission ratio of the input shaft 142 and the output shaft 143.

[0044] Furthermore, based on the feedback of the material conveying volume from the electronic belt scale 8, the power supply time of the electromagnetic connection component 133 is controlled. The larger the conveying volume, the longer the power supply time of the electromagnetic connection component 133. Thus, when the cleaning reminder mechanism 13 is working, each time a material conveying and metering is completed, the control system controls the power supply equipment to supply power to the electromagnetic connection component 133, enabling the input shaft 142 to be connected to the rotating end of the electronic belt scale 8 via the bevel gear assembly 132. Consequently, when the electronic belt scale 8 is working, it synchronously drives the input shaft 142 to rotate. The input shaft 142 then drives the output shaft 143 to rotate via the transmission connection of the V-shaped steel belt transmission belt 1410. The output shaft 143 drives the transmission screw 134 to rotate. Through the threaded connection between the transmission screw 134 and the trigger plate 135, the trigger plate 135 moves toward the trigger switch 136. After multiple material conveying and metering operations, the trigger plate 135 presses against the trigger switch 136, giving the operator a signal to clean the electronic belt scale 8. This prevents material residue from adhering to the electronic belt scale 8 and affecting its metering accuracy. The material will only adhere to the electronic belt scale 8 when its viscosity meets the standard, at which point the cleaning reminder mechanism 13 will be activated. The higher the viscosity of the material, the more material will adhere. By increasing the transmission ratio of the continuously variable transmission mechanism 14, the moving distance of the trigger plate 135 per unit conveying volume is increased, thereby increasing the cleaning frequency. The higher the conveying volume, the more material will adhere. Therefore, by increasing the connection time of the electromagnetic connection component 133, the moving distance of the trigger plate 135 is also increased, shortening the cleaning interval and ensuring the timeliness of the cleaning work.

[0045] Each time the material is metered and conveyed, the operation of the material viscosity detection mechanism 11 synchronously drives the operation of the warning feedback mechanism 12. When the electronic belt scale 8 detects that the conveyed material is metered correctly, the control system controls the pressure relief valve 1217 on the pressure relief pipe 1216 to open. When the metering is incorrect, the control system controls the pressure relief valve 1217 to close. At this time, when the material viscosity detection mechanism 11 is working, the electric push rod 113 synchronously pushes the pressing plate 127 down. The pressing plate 127 acts on the pressure plate 125, causing the pressure plate 125 to work with the pressure rod 124 to overcome the elastic force of the return spring 126 and drive the pressure piston 123 down. The pressure piston 123 delivers the air in the pressure shell 121 to the warning shell 122 through the air supply pipe 1213. Since the pressure relief valve 1217 is closed at this time, the warning shell 121... A sealed space is formed on the inner side of the front end of 2. The gas supply will increase the gas pressure, driving the moving piston 128 to work with the limit slide rod 129 to overcome the elasticity of the push spring 1210 and generate a fixed displacement. When the required material metering requirements cannot be met after three consecutive adjustments to the scraper material taking component 4 based on the metering information fed back by the electronic belt scale 8, that is, the metering results fed back by the electronic belt scale 8 are unqualified for three consecutive times, the pressure relief valve 1217 will remain closed. After three consecutive movements of the moving piston 128, it will press against the warning switch 1211, promptly reminding the staff to perform the corresponding inspection and handling. This indicates that automatic adjustment can no longer solve the problem and there may be a hidden fault (such as hidden sensor damage, slight jamming of mechanical parts, or sudden changes in material characteristics that exceed the system's adaptability range), and manual intervention must be prompted.

[0046] When the test measurement is qualified, the pressure relief valve 1217 will be opened, and the air accumulated in the warning shell 122 will be discharged. Under the action of the push spring 1210, the moving piston 128 will be reset to the initial position to avoid false alarms.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
