[0060] The present application is further described in detail below in conjunction with the accompanying drawings.

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] like Figure 1 The method for speed regulation of a coal mine belt conveyor is described as follows (steps S101 to S105):

[0063] S101: Calculate the minimum transmission speed of the belt conveyor according to the coal flow on the belt conveyor.

[0064] In this embodiment, the coal flow rate can be obtained according to the pressure sensor or the captured image. Since the coal flow rate of the belt conveyor is continuously large and the transmission speed is low, a large amount of coal will accumulate on the belt conveyor, exceeding the upper limit of the belt conveyor transportation, resulting in transportation failures. Therefore, this application calculates the minimum transmission speed of the belt conveyor based on the coal flow rate on the belt conveyor to ensure the normal transportation of the belt conveyor, laying the foundation for subsequently improving the transmission efficiency of the belt conveyor.

[0065] Specifically, the minimum transmission speed of the belt conveyor is calculated according to the coal flow on the belt conveyor, including: obtaining the rated coal flow and rated transmission speed of the belt conveyor; determining the transportation ratio of the belt conveyor according to the rated coal flow and the coal flow; wherein the transportation ratio represents the transportation force ratio output by the belt conveyor; determining the minimum transmission speed of the belt conveyor according to the transportation ratio and the rated transmission speed.

[0066] In this embodiment, the rated coal flow rate is the upper limit of the coal flow rate that the belt conveyor can withstand, the rated transmission speed is the minimum transmission speed under the rated coal flow rate, the rated coal flow rate and the rated transmission speed are both set in advance, the transportation ratio is the ratio of the coal flow rate to the rated coal flow rate, and the minimum transmission speed is the product of the transportation ratio and the rated transmission speed. Since the coal flow rate and the minimum transmission speed are roughly proportional, this application determines the transportation ratio based on the coal flow rate and the rated coal flow rate, and then obtains the minimum transmission speed based on the transportation ratio and the rated transmission speed, laying the foundation for subsequently improving the transmission efficiency of the belt conveyor.

[0067] S102: Determine a transmission speed adjustment range of the belt conveyor according to a minimum transmission speed and a preset maximum transmission speed.

[0068] In this embodiment, the preset maximum transmission speed is set in advance based on the performance of the belt conveyor or based on transportation experience. For example, the stable transportation speed of the belt conveyor under the rated coal flow rate is determined according to the width of the belt conveyor, friction factors, etc., and the transmission speed adjustment range is (minimum transmission speed, preset maximum transmission speed).

[0069] S103: Calculate the transmission efficiency range of the belt conveyor according to the transmission speed adjustment range and the coal flow rate.

[0070] In this embodiment, the transmission efficiency range includes a transmission time efficiency range and a transmission energy efficiency range. The transmission time efficiency indicates the time spent by the belt conveyor to transport coal. The higher the transmission time efficiency, the less time it takes. The transmission energy efficiency indicates the energy loss of the belt conveyor to transport coal. The higher the transmission energy efficiency, the less energy loss. Since there are time limits and energy efficiency constraints in the process of transporting coal by the belt conveyor, the emphasis of the transmission time efficiency and the transmission energy efficiency is different in different situations. When the demand for coal production is high, the priority of the transmission time efficiency is higher than the priority of the transmission energy efficiency; when the demand for coal production is low, the priority of the transmission time efficiency is lower than the priority of the transmission energy efficiency. Therefore, in the process of transporting coal by the belt conveyor, it is necessary to take into account the transmission time efficiency and the transmission energy efficiency according to different situations. Therefore, this application determines the transmission time efficiency range and the transmission energy efficiency range of the belt conveyor according to the transmission speed adjustment range and the coal flow rate, laying a foundation for the subsequent consideration of the transmission time efficiency and the transmission energy efficiency.

[0071] Specifically, the transmission efficiency range of the belt conveyor is calculated according to the transmission speed adjustment range and the coal flow rate, including: obtaining the transmission distance of the coal flow rate; determining the transmission time range of the coal flow rate according to the transmission distance of the coal flow rate and the transmission speed adjustment range; determining the transmission time efficiency range of the belt conveyor according to the transmission time range and the preset standard transmission time.

[0072] In this embodiment, the transmission distance of the coal flow is the transmission distance of the belt conveyor, which is determined by the coal dropping point and the transmission boundary point of the belt conveyor. The transmission time range is obtained by dividing the transmission distance of the coal flow by the transmission speed in the transmission speed adjustment range. The preset standard transmission time is set in advance. The transmission time efficiency range is obtained by dividing the preset standard transmission time and the transmission time in the transmission time range. For example, the transmission distance of the coal flow is 100m, the transmission speed adjustment range is (1m / s, 2m / s), then the transmission time range is (50s, 100s), the preset standard transmission time is 75s, and the transmission time efficiency range is (0.75, 1.5).

[0073] During the process of conveying coal by belt conveyor, it is necessary to maintain the transmission efficiency while taking into account the wear rate of the belt conveyor. The transmission efficiency can be reflected by the transmission time efficiency and the transmission energy efficiency. This application determines the transmission time range of the coal flow through the transmission distance and transmission speed adjustment range of the coal flow, and determines the transmission time efficiency range based on the preset standard transmission time, laying the foundation for the subsequent determination of the target transmission speed of the belt conveyor.

[0074] Furthermore, the transmission efficiency range of the belt conveyor is calculated based on the transmission speed adjustment range and the coal flow rate, and the method also includes: obtaining parameter information of the belt conveyor; wherein the parameter information includes friction parameters; determining the positive pressure of the coal flow rate on the belt conveyor based on the coal flow rate and the inclination of the belt conveyor; determining the energy loss range of the belt conveyor based on the positive pressure, parameter information and transmission speed adjustment range; calculating the useful work of the belt conveyor based on the coal flow rate and the transmission distance of the coal flow rate; and determining the transmission energy efficiency range of the belt conveyor based on the energy loss range and the useful work.

[0075] In this embodiment, the friction parameters include the dynamic friction coefficient and static friction coefficient of the belt conveyor, and the parameter information also includes the relationship between the positive pressure and the pressure of the belt and the motor. According to the gravity and inclination of the coal flow, the component force of the gravity of the coal flow perpendicular to the belt conveyor is determined as the positive pressure. When the inclination of the belt conveyor is not zero, the useful work of the belt conveyor is the product of the component force of the gravity of the coal flow along the belt conveyor and the transmission distance of the coal flow. When the inclination of the belt conveyor is zero, the useful work of the belt conveyor is the product of the gravity of the coal flow and the transmission distance.

[0076] The energy loss is divided into the energy loss caused by the sliding friction between the coal and the belt conveyor and the energy loss caused by the friction between the belt and the motor of the belt conveyor. When the transmission speed is lower than the preset slip speed, the energy loss caused by the sliding friction between the coal and the belt conveyor is not considered. At this time, the pressure between the belt and the motor of the belt conveyor is obtained based on the positive pressure and parameter information, and the energy loss caused by the friction between the belt and the motor of the belt conveyor is determined based on the transmission speed, the transmission distance of the coal flow and the static friction coefficient, so as to obtain the energy loss range; when the transmission speed is higher than the preset slip speed, based on the energy loss caused by the friction between the belt and the motor of the belt conveyor, the energy loss caused by the sliding friction between the coal and the belt conveyor is added, and the coal flow and the sliding friction of the belt conveyor are determined according to the dynamic friction coefficient and positive pressure of the belt conveyor. Based on the transmission speed and the dynamic friction coefficient, the sliding distance of the coal flow is determined, and the energy loss caused by the sliding friction between the coal and the belt conveyor is obtained based on the sliding friction and the sliding distance.

[0077] The total work is determined based on the useful work and the energy loss, and the transmission energy efficiency is obtained according to the ratio of the useful work to the total work. The transmission energy efficiency range includes all transmission energy efficiencies.

[0078] Since the energy loss in the process of transporting coal by a belt conveyor mainly comes from the friction between the coal and the belt conveyor and the friction caused by the belt conveyor transmission, when calculating the transmission energy efficiency, the present application divides the energy loss into two parts: the energy loss caused by the sliding friction between the coal and the belt conveyor and the energy loss caused by the friction between the belt of the belt conveyor and the motor, thereby improving the accuracy of the transmission energy efficiency.

[0079] S104: Calculate the wear rate range of the belt conveyor according to the transmission speed adjustment range and the coal flow rate.

[0080] In this embodiment, the wear rate range determines the unit wear information of the belt conveyor through the transmission speed adjustment range, coal flow rate and the preset influencing factor-wear table, and then determines the wear range of the belt conveyor according to the unit wear information and the transmission distance of the coal flow rate. Since the higher the transmission efficiency, the higher the wear rate of the belt conveyor, the repair of the worn and damaged belt conveyor will lead to a decrease in transmission efficiency. While ensuring the transmission efficiency, the sustainable operation of the belt conveyor must also be taken into account. Therefore, this application determines the wear rate range of the belt conveyor according to the transmission speed adjustment range and the coal flow rate, laying a foundation for the subsequent improvement of the transmission efficiency of the belt conveyor while taking into account the sustainable operation of the belt conveyor.

[0081] Specifically, the wear rate range of the belt conveyor is calculated according to the transmission speed adjustment range and the coal flow rate, including: determining the unit wear information of the belt conveyor according to the transmission speed adjustment range, the coal flow rate and the preset influencing factor-wear table; wherein the preset influencing factor-wear table represents a relationship correspondence table among the transmission speed adjustment range, the coal flow rate and the unit wear degree; determining the wear rate range of the belt conveyor according to the unit wear information and the transmission distance of the coal flow rate.

[0082] In this embodiment, the preset influencing factor-wear table characterizes the relationship between the transmission speed adjustment range, the coal flow rate and the unit wear degree. The unit wear degree of the belt conveyor can be determined by the transmission speed and the coal flow rate. The preset influencing factor-wear table can be obtained in advance based on a preliminary experiment. For example, the preliminary experiment can be to adjust the transmission speed once with a constant coal flow rate, and obtain the wear thickness of the belt conveyor under a long transmission distance, thereby determining the relationship between the coal flow rate, the transmission speed and the unit wear degree. It can also be obtained based on theoretical calculations, for example, according to the parameter information of the belt conveyor and the coal flow rate and the transmission speed, the relationship between the coal flow rate, the transmission speed and the unit wear degree is calculated. The unit wear information includes all unit wear degrees within the range of coal flow rate and transmission speed. The unit wear degree is the wear thickness of the belt conveyor under the unit transmission distance. The wear rate range is obtained based on the product of the unit wear degree in the unit wear information and the transmission distance.

[0083] S105: Determine a target transmission speed of the belt conveyor according to a transmission efficiency range and a wear rate range.

[0084] Specifically, the target transmission speed of the belt conveyor is determined according to the transmission efficiency range and the wear rate range, including: respectively obtaining the preset weights of the transmission time efficiency, the transmission energy efficiency and the wear rate; and determining the target transmission speed according to the transmission time efficiency, the transmission energy efficiency, the wear rate and all the preset weights.

[0085] In this embodiment, the preset weights can be set in advance according to the preferences of transmission time efficiency, transmission energy efficiency and wear rate in the process of coal transportation. For example, when the demand for coal mining output increases, transmission time efficiency takes precedence, transmission energy efficiency takes second place, and wear rate takes last place. Then the transmission time efficiency preset weight> transmission energy efficiency preset weight> wear rate preset weight; the transmission time efficiency, transmission energy efficiency and wear rate preset weights can also be set in advance according to the type of coal mine or coal cohesion. For example, since non-sticky coal has poor cohesion, the transmission speed cannot be too fast. At this time, the wear rate preset weight> transmission time efficiency preset weight> transmission energy efficiency preset weight. Transmission time efficiency preset weight+transmission energy efficiency preset weight+wear rate preset weight=1.

[0086] During the coal transportation process, preset weights are set for the transmission time efficiency, transmission energy efficiency and wear rate. The target transmission speed is determined based on the transmission time efficiency, transmission energy efficiency, wear rate and all preset weights. This can enable the belt conveyor to meet the coal transportation needs to the greatest extent while taking into account the transmission time efficiency, transmission energy efficiency and wear rate.

[0087] Furthermore, the target transmission speed is determined according to the transmission time efficiency, transmission energy efficiency, wear rate and all preset weights, including: according to the transmission speed adjustment range, the transmission time efficiency range, the transmission energy efficiency range and the wear rate range are matched one by one to determine the transmission time efficiency, transmission energy efficiency and wear rate corresponding to each transmission speed; according to the transmission time efficiency, transmission energy efficiency and wear rate corresponding to the transmission speed and all preset weights, the balance of the transmission speed is determined; according to the balance of all transmission speeds, the target transmission speed is determined.

[0088] In this embodiment, , where Y represents the balance of transmission speed, A represents the transmission time efficiency, B represents the transmission energy efficiency, C represents the wear rate, A1 represents the preset weight of transmission time efficiency, B1 represents the preset weight of transmission energy efficiency, and C1 represents the preset weight of wear rate.

[0089] The transmission speed corresponding to the highest balance is selected as the target transmission speed.
