Description

Technical Field

[0001] This invention relates to the field of scraper conveyor technology, and in particular to a method and system for predicting the wear degree of the upper edge of a transition trough, and a scraper conveyor. Background Technology

[0002] Scraper conveyors are crucial material handling equipment in underground mining operations. The transition trough, a vital component, connects the conveyor's head, tail, and middle sections. During operation, the scraper chain assembly of the conveyor exerts pressure on the transition trough, causing wear on its upper edge. When this wear reaches a certain level, the upper edge may break, leading to scraper detachment and other problems. This not only disrupts continuous equipment operation but can also cause safety accidents. Therefore, predicting the wear level of the transition trough's upper edge is essential. However, current equipment lacks methods for predicting this wear level. Summary of the Invention

The pressure monitoring unit is installed inside the side wall of the transition groove and located directly below the detachable upper edge structure. The lower end of the connecting rod is connected to the pressure monitoring unit, and the upper end of the connecting rod is fixed to the detachable upper edge structure. When the axe end of the scraper passes through the detachable upper edge structure, the axe end of the scraper will press against the lower surface of the detachable upper edge structure, causing the connecting rod to drive the pressure monitoring unit to move upward, forcing the pressure monitoring unit to press against the side wall of the transition groove, so as to realize the acquisition of pressure data.

[0007] The controller establishes a communication connection with the pressure monitoring unit. The controller can process the acquired pressure data and compare it with a pre-built wear life model to predict the wear life of the upper edge of the transition groove.

[0024] Preferably, in steps S3 and S4, the remaining wear-bearing capacity h1 along the upper edge of the transition groove during the first stroke is obtained in the following way:

[0025] h1=H-n1×t

[0026] H = N × T

[0027] Where H represents the theoretical wear life of the upper edge, N represents the theoretical pressure of the upper edge, and T represents the theoretical wear time of the upper edge.

[0045] A scraper conveyor includes the aforementioned wear prediction system for the upper edge of the transition trough, the system being installed on a PLC control cabinet used in conjunction with the scraper conveyor.

[0046] Compared with existing technologies, the present invention provides a method and system for predicting the wear degree of the upper edge of the transition groove, as well as a scraper conveyor. A detachable upper edge structure is provided at the upper edge of the transition groove. This detachable upper edge structure is fixed to the transition groove frame via a connecting rod and a mounting base with a pressure sensor. When the scraper chain passes through the detachable upper edge structure, the scraper presses against the upper edge. The upper edge, through the connecting rod, drives the mounting base of the pressure sensor. The mounting base is pressed against the mounting hole on the transition groove frame. The pressure sensor records the pressure data and transmits it to the system controller. Based on the data recorded by the pressure sensor, and according to the wear principle, the system controller determines that the degree of frictional wear between the upper edge and the scraper assembly is proportional to the frictional force between them. Since the frictional force is proportional to the magnitude of the pressing force, the system can predict and calculate the wear degree and lifespan of the upper edge of the transition groove by recording the pressure sensor data per unit time.

[0056] 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. 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.

[0057] In the description of this invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0058] Please refer to Figures 1 to 7 In one embodiment, the present invention provides a system for predicting the wear degree of the upper edge of a transition groove, including a pressure detection component, a detachable upper edge structure, and a controller;

[0059] The detachable upper edge structure is installed along the length of the transition groove at its upper edge. Alternatively, the detachable upper edge structure can cover the entire upper edge of the transition groove, or a certain distance can be reserved at the upper edge for its installation. When a reserved distance is used, the length of the detachable upper edge structure is 5%-15% of the length of the transition groove, and its installation position is chosen to be within 40%-60% of the transverse length of the upper edge of the transition groove to ensure accurate measurement data.

[0060] The pressure detection assembly includes a pressure monitoring unit and a connecting rod. The pressure monitoring unit is installed inside the side wall of the transition groove and located directly below the detachable upper edge structure. The lower end of the connecting rod is connected to the pressure monitoring unit, and the upper end of the connecting rod is fixed to the detachable upper edge structure. When the axe end of the scraper passes through the detachable upper edge structure, the axe end of the scraper will press against the lower surface of the detachable upper edge structure, causing the connecting rod to drive the pressure monitoring unit to move upward, forcing the pressure monitoring unit to be pressed against the side wall of the transition groove, so as to realize the acquisition of pressure data.

[0061] The controller establishes a communication connection with the pressure monitoring unit to acquire pressure data. The controller processes this pressure data and compares it with a pre-built wear life model to predict the wear life of the upper edge of the transition groove. The controller can establish a communication connection with the pressure monitoring unit via wireless or wired communication. When using wireless communication, a data link can be established through technologies such as WiFi, Bluetooth, 4G, 5G, and LoRa to achieve data transmission and remote control.

[0062] Specifically, the pressure monitoring unit includes a mounting base and a pressure sensor. A connection hole is provided on the side wall of the mounting base, and the connection hole is arranged radially along the mounting base. The connection hole is used to connect with a connecting rod, and the connection between the connection hole and the end of the connecting rod can be achieved by a threaded connection for easy disassembly and installation. Correspondingly, the pressure sensor is mounted on the side wall of the mounting base along the axial direction of the connection hole, and the pressure sensor is located on the side facing the opening of the connection hole.

[0063] More specifically, the transition groove has mounting holes on its sidewalls for a direction perpendicular to the axial direction of the connecting hole, and a guide hole at the top of the transition groove for inserting the connecting rod and communicating with the mounting holes. When the connecting rod passes through the guide hole, the connecting rod and the guide hole form a sliding fit; of course, lubricating oil or grease can be applied to the connecting rod and the inner wall of the guide hole to reduce the resistance between the connecting rod and the guide hole.

[0064] The number of pressure monitoring units is ≥3, and the number of units is matched with the number of mounting holes and guide holes.

[0065] In this design, when the scraper's axe-shaped end presses against the lower surface of the detachable upper edge structure, it exerts upward pressure on the structure, causing the connecting rod to move the mounting base column upwards. This forces the pressure sensor to press against the top of the inner wall of the mounting hole, thus collecting pressure data. This indicates that the scraper's axe-shaped end causes wear on the detachable upper edge structure. However, when the scraper's axe-shaped end moves away from the detachable upper edge structure, it no longer exerts upward pressure. Under its own weight, the detachable upper edge structure tends to move downwards, preventing the pressure sensor from pressing against the top of the inner wall of the mounting hole. In this case, no pressure data is collected, indicating that the scraper's axe-shaped end does not cause wear on the detachable upper edge structure.

[0066] In one embodiment, the present invention provides a method for predicting the wear level of the upper edge of a transition groove. The method uses a transition groove upper edge wear level prediction system to predict the wear level of the upper edge of the transition groove. The specific steps are as follows:

[0067] Step S1: Number each scraper sequentially as {1,2,......,m}. Define the time required from the first scraper to the point where the pressure detection component is installed at the upper edge of the transition groove as one stroke, and t as the time required.

[0068] The pressure data recorded by the pressure detection component when the axe end of each scraper presses against the upper edge of the transition groove is acquired. The number of pressure sensors, δ, is reliably determined based on usage requirements. For example, if three pressure sensors are installed along the upper edge of the transition groove, they can be labeled a, b, and c, respectively. That is, the pressure data acquired by pressure sensor a can be represented as a1...a1. m The pressure data acquired by pressure sensor b can be represented as b1...b m The pressure data acquired by pressure sensor c can be represented as c1......c m .

[0069] Step S2: Based on the recorded pressure data, obtain the average pressure n1 at the upper edge of the transition groove during the first stroke within time t.

[0070]

[0071] Step S3: Based on the average pressure n1, obtain the remaining wear-bearing capacity h1 at the upper edge of the transition groove during the first stroke.

[0072] h1=H-n1×t

[0073] H = N × T

[0074] Where H represents the theoretical wear life of the upper edge, N represents the theoretical pressure of the upper edge, and T represents the theoretical wear time of the upper edge.

[0075] Step S4: Based on the remaining wearable amount h1 at the upper edge of the transition groove during the first stroke, obtain the remaining wear life S1 at the upper edge of the transition groove during the first stroke.

[0076]

[0077] Where h1 represents the remaining wear-bearing capacity of the upper edge of the transition groove during the first stroke, and n1 represents the average pressure at the upper edge of the transition groove during the first stroke.

[0078] Step S5: The second stroke is recorded as the time required for the first scraper to pass the pressure detection component at the upper edge of the transition groove again.

[0079] Obtain the pressure data recorded by the pressure detection component when the axe end of each scraper presses against the upper edge of the transition groove, and obtain the average pressure n2 at the upper edge of the transition groove during the second stroke within time t; the calculation method of the average pressure n2 is the same as the calculation method of the average pressure n1.

[0080] Step S6: Based on the average pressure n1 and average pressure n2, obtain the remaining wear allowance h2 along the upper edge of the transition groove during the second stroke.

[0081] h2 = Ht(n1 + n2)

[0082] H = N × T

[0083] Where n1 represents the average pressure at the upper edge of the transition groove during the first stroke, n2 represents the average pressure at the upper edge of the transition groove during the second stroke, H represents the theoretical wear life of the upper edge, N represents the theoretical pressure of the upper edge, and T represents the theoretical wear time of the upper edge.

[0084] Step S7: Based on the remaining wearable amount h2 at the upper edge of the transition groove during the second stroke, obtain the remaining wear life S2 at the upper edge of the transition groove during the second stroke.

[0085]

[0086] Where n1 represents the average pressure at the upper edge of the transition groove during the first stroke, and n2 represents the average pressure at the upper edge of the transition groove during the second stroke.

[0087] Step S8: The time required for the first scraper to pass the pressure detection component at the upper edge of the transition groove again is recorded as the y-th stroke;

[0088] Obtain the pressure data recorded by the pressure detection component when the axe end of each scraper is pressed against the upper edge of the transition groove, and obtain the average pressure n at the upper edge of the transition groove during the y-th stroke within time t. y The average pressure n y The calculation method is the same as the calculation method for the average pressure n1.

[0089] Step S9: Based on the average pressure n1, n 2...... ,n y The remaining wear-bearing amount h at the upper edge of the transition groove during the y-th stroke is obtained. y ,but

[0090] h y =Ht(n1+n2+......n) y )

[0091] H = N × T

[0092] Where H represents the theoretical wear life of the upper edge, N represents the theoretical pressure of the upper edge, T represents the theoretical wear time of the upper edge, n1 represents the average pressure at the upper edge of the transition groove during the first stroke, and n2 represents the average pressure at the upper edge of the transition groove during the second stroke.

[0093] Step S10: Based on the remaining wear allowance h at the upper edge of the transition groove during the y-th stroke. y Obtain the remaining wear life S of the upper edge of the transition groove during the y-th stroke. y ,but

[0094]

[0095] Where n1 represents the average pressure at the upper edge of the transition groove during the first stroke, n2 represents the average pressure at the upper edge of the transition groove during the second stroke, and y represents the number of strokes of the scraper.

[0096] To better understand this invention, let's take a scraper conveyor as an example. Assume that the scraper conveyor has 300 scrapers. Then, the theoretically set initial wear life of the upper edge is: H = N × T = 1000 Newtons × 1000 minutes = 1000000 Newtons per minute.

[0097] Taking the first stroke of the scraper as an example, after the scraper conveyor is started, the time from the 1st to the 300th scraper to the upper edge of the three pressure sensors a, b, and c is 5 minutes. The pressure data of the three pressure sensors a, b, and c are recorded, and the average pressure n1 = 3000 Newtons at the upper edge within time t is calculated.

[0098] Therefore, after the first stroke, the remaining wear allowance h1 along the upper edge of the transition groove can be calculated as follows:

[0099] h1 = 1,000,000 Newtons per minute - 3,000 Newtons × 5 minutes = 985,000 Newtons per minute.

[0100] Therefore, after the first stroke, the remaining wear life S1 along the upper edge of the transition groove can be calculated as follows:

[0101]

[0102] Taking the second stroke of the scraper as an example, the time it takes for the scrapers from the 1st to the 300th to pass the upper edge of the three pressure sensors a, b, and c is 5 minutes. The pressure data of the three pressure sensors a, b, and c are recorded, and the average pressure n1 = 2000 Newtons at the upper edge within time t is calculated.

[0103] Therefore, after the second stroke, the remaining wear allowance h2 along the upper edge of the transition groove can be calculated as follows:

[0104] h² = 1,000,000 Newtons per minute - 3,000 Newtons × 5 minutes - 2,000 Newtons × 5 minutes =

[0105] 975,000 Newton-minutes.

[0106] Therefore, after the second stroke, the remaining wear life S2 along the upper edge of the transition groove can be calculated as follows:

[0107]

[0108] Similarly, when the scraper completes its y-th stroke, the remaining wear life S of the upper edge of the transition groove can be obtained using the above method. y This enables the prediction of wear life along the upper edge of the transition groove.

[0109] In one embodiment, the present invention provides a scraper conveyor including a wear prediction system for the upper edge of the transition groove; wherein, the controller is installed on a PLC control cabinet, the PLC control cabinet has a memory, the memory stores a method for predicting the wear prediction of the upper edge of the transition groove, enabling the controller to execute the method for predicting the wear prediction of the upper edge of the transition groove, thereby predicting the wear life of the upper edge of the transition groove.

[0110] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
