Description

Belt conveyor Technical Field

[0001] This invention relates to the field of coal mining technology, and more specifically, to a belt conveyor. Background Technology

[0002] In coal mining and other mineral resource extraction industries, telescopic belt conveyors are key material handling equipment used to continuously transport materials such as coal and ore from the working face to the surface or the next processing point. The unique telescopic nature of these conveyors allows them to adapt to the continuous forward or backward movement of the working face, thus maintaining the continuity and efficiency of material transport.

[0003] The core components of a retractable belt conveyor are the belt storage bin and the tensioning device. The belt storage bin stores additional conveyor belts and can release or retract the belts when the conveyor moves forward or backward, thus enabling the conveyor to extend or retract. The tensioning device is responsible for adjusting the tension of the conveyor belt to ensure its stability and efficiency during transport.

[0004] In related technologies, when it is necessary to adjust the tail position of the conveyor to adapt to changes in the working face, the operator makes a subjective judgment by combining manual observation with experience to estimate the remaining amount of conveyor belt in the storage bin and control the adjustment of the tail position of the telescopic belt conveyor.

[0005] However, when it is necessary to adjust the tail position to adapt to changes in the working face, the adjustment methods in related technologies rely on the operator's subjective judgment, which has the problem of inaccuracy. Summary of the Invention

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] As shown in Figure 1, this embodiment of the invention provides a belt conveyor. The belt conveyor includes a frame, a roller assembly 10, a belt storage unit 20, a conveyor belt 30, a tension adjusting unit 40, a distance measuring unit, and a control unit. The roller assembly 10 includes a head roller 11, a tail roller 12, and a drive unit. The head roller 11 and the tail roller 12 are rotatably mounted on the frame. The drive unit is drivenly connected to either the head roller 11 or the tail roller 12. The rotation axis of the head roller 11 and the rotation axis of the tail roller 12 both extend along the width direction of the frame. The tail roller 12 can move along the length direction of the frame. The belt storage unit 20 is movably mounted on the frame. In the frame, the direction of movement of the belt storage unit 20 is perpendicular to the width direction of the frame. The conveyor belt 30 is wound around the head roller 11, the tail roller 12 and the belt storage unit 20. The tension adjustment unit 40 includes a first adjustment unit and a second adjustment unit 41. The first adjustment unit can adjust the position of the tail roller 12 relative to the frame, and the second adjustment unit 41 can adjust the position of the belt storage unit 20 relative to the frame. The distance measuring unit can detect the movement distance of the belt storage unit 20 and the tail roller 12. The control unit is connected to the distance measuring unit, the first adjustment unit and the second adjustment unit 41 by signal, so as to control the operation of the first adjustment unit and the second adjustment unit 41 according to the detection result of the distance measuring unit.

[0027] The belt conveyor provided in this embodiment includes a frame, a roller assembly 10, a belt storage unit 20, a conveyor belt 30, a tension adjustment unit 40, a distance measuring unit, and a control unit. As the tail roller 12 approaches the head roller 11, the distance measuring unit detects the movement distance of the tail roller 12. The control unit calculates the required movement distance of the belt storage unit 20 based on the movement distance of the tail roller 12 according to a preset proportional parameter. The control unit controls the second adjustment unit 41 to adjust the position of the belt storage unit 20 relative to the frame, so that the belt storage unit 20 moves away from the head roller 11 until the movement distance meets the required movement distance of the belt storage unit 20. Similarly, as the belt storage unit 20 approaches the head roller 11, the distance measuring unit detects the movement distance of the belt storage unit 20. The control unit calculates the required movement distance of the tail roller 12 based on the movement distance of the belt storage unit 20 according to a preset proportional parameter. The control unit controls the first adjustment unit to adjust the position of the tail roller 12 relative to the frame, so that the tail roller 12 moves away from the head roller 11 until the movement distance meets the required movement distance of the tail roller 12. The belt conveyor provided in this embodiment utilizes a rangefinder to detect the movement distance of the belt storage unit 20 and the tail roller 12, improving the accuracy of detecting the position of the belt storage unit 20 relative to the frame and the position of the tail roller 12 relative to the frame. Furthermore, the control unit controls the operation of the first and second adjustment units 41 based on the detection results of the rangefinder, avoiding the roughness and uncertainty of position adjustments for the belt storage unit 20 and the tail roller 12, eliminating reliance on operator experience, eliminating the need for frequent manual adjustments and monitoring, reducing the daily operation and maintenance costs of the belt conveyor, improving material conveying efficiency, reducing energy consumption and production costs, and increasing the automation level of operations for retracting or extending the tail position of the belt conveyor, thereby improving production efficiency and operational safety.

[0028] In this embodiment, the control unit includes a communication unit and a data analysis unit. The communication unit is signal-connected to the ranging unit to receive the detection results from the ranging unit. The data analysis unit is signal-connected to the communication unit to analyze the data received by the communication unit. The communication unit is also signal-connected to the first adjusting unit and the second adjusting unit 41, respectively, to control the operation of the first adjusting unit and the second adjusting unit 41 according to the analysis results of the data analysis unit. By using the communication unit to receive the detection results from the ranging unit, and the data analysis unit to analyze the data received by the communication unit to obtain the target moving distance, the communication unit controls the operation of the first adjusting unit or the second adjusting unit 41 according to the target moving distance, automatically adjusting the position of the tail roller 12 and the belt storage unit 20, ensuring that the belt conveyor can operate stably even in dynamically changing environments, effectively avoiding the problems of conveyor belt slippage or over-tension, and improving the adaptability and reliability of the conveyor.

[0029] In this embodiment, the control unit also includes an input unit, which is signal-connected to the data analysis unit to modify the analysis parameters of the data analysis unit based on the input information. Operators can use the input unit to adjust the analysis parameters (i.e., preset proportional parameters) of the data analysis unit according to actual needs, improving the flexibility of the control unit.

[0030] In this embodiment, the ranging device is a millimeter-level laser rangefinder. Using a millimeter-level laser rangefinder as the ranging device can improve the accuracy of the measurement results and the adjustment accuracy of the tension adjustment device 40.

[0031] In this embodiment, the ranging device includes a first ranging element and a second ranging element. The first ranging element can detect the moving distance of the belt storage unit 20, and the second ranging element can detect the moving distance of the tail roller 12. By using the first ranging element and the second ranging element to detect the moving distance of the belt storage unit 20 and the moving distance of the tail roller 12 respectively, the measurement error that may be caused by a single ranging element is avoided, the accuracy of the measurement results is improved, the adjustment accuracy of the tension adjustment component 40 is improved, and the operating efficiency and safety of the conveyor are improved.

[0032] In this embodiment, the first ranging element includes a first transmitter and a first receiver, and the second ranging element includes a second transmitter and a second receiver. Both the first and second transmitters are mounted on the frame, the first receiver is mounted on the belt storage unit 20, and the second receiver is mounted on the tail roller 12. Both the first and second receivers are signal-connected to the control unit. Using the aforementioned first and second ranging elements, the separate transmitter and receiver design avoids interference from the conveyor belt 30 and the conveyed material on the ranging signal, improving the accuracy and stability of the ranging. This design is suitable for material conveying under complex working conditions, such as open-pit mines and construction sites.

[0033] In this embodiment, the belt conveyor also includes an alarm device. The control device is signal-connected to the alarm device to control its operation based on the detection results of the ranging device. When the ranging device detects that the position of the tail roller 12 relative to the frame exceeds the safe range, the control device controls the alarm device to issue an alarm in a timely manner and records the abnormal data to facilitate subsequent troubleshooting and maintenance. This improves the intelligent management level of the conveyor and is suitable for unattended or remotely monitored operating environments, such as automated production lines and remote mines.

[0034] In this embodiment, the belt conveyor also includes a data storage device, which is signal-connected to the distance measuring device to store the detection results of the distance measuring device. This allows the operating data of the belt conveyor (the moving distance of the belt storage device 20 and the moving distance of the tail roller 12 detected by the distance measuring device) to be systematically recorded and analyzed. This is beneficial for a deeper understanding and optimization of the conveyor performance and for improving the level of precision in mine production management.

[0035] As shown in Figure 1, the belt storage unit 20 includes a belt storage bin 21 and a belt storage roller 22. The belt storage bin 21 is movably mounted on the frame, and the direction of movement of the belt storage bin 21 is perpendicular to the width direction of the frame. A second adjusting member 41 is disposed between the belt storage bin 21 and the frame to adjust the position of the belt storage bin 21 relative to the frame. The belt storage roller 22 is rotatably mounted inside the belt storage bin 21, and the rotation axis of the belt storage roller 22 is parallel to the rotation axis of the head roller 11. The conveyor belt 30 is wound around the head roller 11, the tail roller 12, and the belt storage roller 22. Through the design of the belt storage bin 21 and the belt storage roller 22, the belt storage bin 21 protects the belt storage roller 22 and the conveyor belt 30 wound around the belt storage roller 22.

[0036] In this embodiment, the belt conveyor also includes a first guide rail, which is mounted on the frame and extends along the length of the frame. The tail roller 12 is movably mounted on the first guide rail along its extension direction. The guiding effect of the first guide rail makes the movement of the tail roller 12 smoother and more precise, improving the operating efficiency and stability of the belt conveyor. This makes it suitable for long-distance conveying and scenarios requiring high-precision positioning, such as container loading and unloading in large ports and production lines for precision electronic equipment.

[0037] In this embodiment, the belt conveyor also includes a tailstock, which is movably mounted on the frame along its length. A first adjusting member can adjust the position of the tailstock relative to the frame. The tail roller 12 is rotatably mounted on the tailstock, and a ranging member can detect the movement distance of the tailstock. The supporting effect of the tailstock makes the movement of the tail roller 12 more stable and precise, improving the operating efficiency and stability of the belt conveyor. This makes it suitable for long-distance conveying and scenarios requiring high-precision positioning, such as container loading and unloading in large ports and production lines for precision electronic equipment.

[0038] In this embodiment, the movement direction of the belt storage unit 20 is parallel to the length direction of the frame. The belt storage unit 20, designed with the aforementioned movement direction, can save the additional space required for the belt storage unit 20 and improve the structural compactness of the belt conveyor.

[0039] In this embodiment, the belt conveyor also includes a second guide rail, which is mounted on the frame. The belt storage unit 20 is movably mounted on the second guide rail along its extension direction. This makes the movement of the belt storage unit 20 smoother and more precise, improving the operating efficiency and stability of the belt conveyor. It is suitable for long-distance conveying and scenarios requiring high-precision positioning, such as container loading and unloading in large ports and production lines for precision electronic equipment.
