Description

Technical Field

[0001] This application belongs to the field of mining monitoring technology, specifically relating to a detection module and a scraper conveyor. Background Technology

[0002] Scraper conveyors are the most important conveying equipment in fully mechanized mining systems. The central trough, as the main component for transporting coal, is continuously subjected to wear and tear from the scrapers, scraper chain, and the transported coal. Therefore, the central trough is the most frequently consumed, replaced, and repaired component on a scraper conveyor. Wear on the central trough's center plate is the primary cause of its maintenance and replacement. Wear detection of the central trough's center plate can provide effective data support for research on center plate wear and real-time early warning of excessive wear.

[0003] Currently, the wear measurement method for the middle plate of the scraper conveyor trough is still manual measurement. This method requires manually cleaning the coal covering the middle plate of the middle plate during equipment shutdown and maintenance, and then using a handheld measuring instrument for measurement. This is not only inefficient and labor-intensive, but also cannot obtain real-time continuous detection data, cannot provide real-time early warning of excessive wear of the middle plate of the middle plate, and cannot provide effective data support for the study of wear of the middle plate of the scraper conveyor trough. Summary of the Invention

The optical fiber mounting plane is used to install optical fibers. The optical fiber arrangement rod is encapsulated in the receiving cavity so that the optical fiber mounting plane and the receiving cavity form a wiring channel.

[0006] Optionally, the fiber optic arrangement rod has fiber optic mounting holes, both ends of which penetrate the fiber optic mounting plane, and the fiber optic cable is installed inside the fiber optic mounting hole.

[0007] Optionally, at least two rows of fiber mounting holes are provided along the axial direction of the fiber arrangement rod, and the two rows of fiber mounting holes are arranged alternately.

[0008] Optionally, the test rod further includes a base and a limiting block. The fiber optic arrangement rod is disposed on the base, and the limiting block is disposed on the base. One side of the limiting block is in contact with the side wall of the fiber optic arrangement rod. The limiting block is connected to the protective housing so that the fiber optic arrangement rod is encapsulated in the protective housing.

[0009] Optionally, the protective housing has a connecting block at its open end, which abuts against the limiting block, and the portion of the protective housing without the connecting block abuts against the base, so that the optical fiber arrangement rod is encapsulated within the protective housing.

[0010] Optionally, the protective housing has an open end sidewall with a fiber optic inlet and a fiber optic outlet arranged opposite to each other, the fiber optic inlet and the fiber optic outlet being respectively arranged corresponding to the fiber optic mounting plane.

[0011] Optionally, both the fiber optic inlet and the fiber optic outlet have rounded transition structures at their edges.

[0012] Optionally, the wiring channel is filled with encapsulating colloid, which wraps around and fixes the optical fiber located in the wiring channel, and the encapsulating colloid bonds the optical fiber arrangement rod to the inner wall of the protective shell into an integral structure.

[0014] A second aspect of this application provides a scraper conveyor, including the detection module described in any one of the above embodiments, and further including a central trough, the central trough including a central plate, the detection module being mounted on the central plate.

[0015] By employing the above technical solution, the present invention has at least the following beneficial effects: The purpose of this application is to provide a detection module and a scraper conveyor. By installing the detection module inside the middle plate of the scraper conveyor trough, there is no need for equipment shutdown for maintenance or manual cleaning of coal on the surface of the middle plate, completely eliminating the interference of traditional manual measurement on the work process. Compared with the operation mode of manually holding a measuring instrument, it not only significantly reduces the labor intensity of workers, but also avoids the efficiency loss caused by cleaning, positioning, and reading in manual measurement, realizing uninterrupted detection of middle plate wear and significantly improving the overall efficiency of wear detection.

[0016] The detection module, through its pre-embedded optical fiber design, can capture the real-time state changes of the middle plate during the wear process caused by the scraper, scraper chain, and coal extrusion, obtaining continuous wear data. This data not only provides accurate and complete basic data support for the study of the wear mechanism of the middle plate in the central trough, filling the gap that traditional manual measurement cannot provide continuous data; but also, through the on / off changes of the optical fiber signal, it can promptly reflect the wear degree of the middle plate, realizing real-time early warning of excessive wear, and effectively avoiding risks such as equipment failure and production interruption caused by excessive wear of the middle plate.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See also Figures 1 to 2As shown, according to a first aspect of the embodiments of this application, a detection module is provided, including a protective housing 101 and a test rod; the internal cavity of the protective housing 101 forms a receiving cavity; the test rod includes an optical fiber arrangement rod 201, and an optical fiber mounting plane 202 is provided on the opposite side of the optical fiber arrangement rod 201, the optical fiber mounting plane 202 being used to install optical fibers; the optical fiber arrangement rod 201 is encapsulated in the receiving cavity so that the optical fiber mounting plane 202 and the receiving cavity form a wiring channel.

[0024] By installing the detection module inside the middle plate of the scraper conveyor trough, no equipment downtime for maintenance or manual cleaning of coal on the middle plate surface is required, completely eliminating the interference of traditional manual measurement on the work process. Compared to the manual operation of handheld measuring instruments, this not only significantly reduces the labor intensity of workers but also avoids the efficiency losses caused by cleaning, positioning, and reading in manual measurement, achieving uninterrupted detection of middle plate wear and significantly improving the overall efficiency of wear detection. The detection module, through its pre-embedded optical fiber design, can capture the real-time state changes of the middle plate during the wear process caused by the scraper, scraper chain, and coal extrusion, obtaining continuous wear data. This data not only provides accurate and complete basic data support for the study of the wear mechanism of the middle plate in the central trough, filling the gap that traditional manual measurement cannot provide continuous data; but also, through the on / off changes of the optical fiber signal, it can promptly reflect the wear degree of the middle plate, realizing real-time early warning of excessive wear, and effectively avoiding risks such as equipment failure and production interruption caused by excessive wear of the middle plate.

[0025] The protective housing 101 has a cylindrical shape and an internal cavity that is a cylindrical receiving cavity. The protective housing 101 prevents the optical fiber on the test rod from being damaged by abnormal wear during measurement.

[0026] The test rod includes an optical fiber arrangement rod 201, which has a cylindrical rod structure. Opposite sides of the rod 201 are cut into planes, forming two optical fiber mounting planes 202 parallel to the rod's axis. These two mounting planes 202 are symmetrically distributed and parallel to the upper and lower end faces of the central trough plate of the scraper conveyor. The mounting planes 202 are used to mount optical fibers, providing a stable reference surface for the processing of the optical fiber mounting holes 203 and optical fiber assembly. The optical fiber arrangement rod 201 is encapsulated within a cavity, allowing the mounting planes 202 and the cavity to form a routing channel. This channel ensures the optical fiber can pass through while maintaining the vertical orientation of the fibers on both sides, effectively preventing crosstalk interference during fiber wear.

[0027] The unprocessed fiber mounting plane 202 of the fiber optic rod 201 has an arc-shaped surface. When the fiber optic rod 201 is installed in the cavity, the arc-shaped surface of the fiber optic rod 201 fits against the inner arc surface of the cavity to ensure coaxiality between the two.

[0028] In another embodiment, the fiber optic arrangement rod 201 has a fiber optic mounting hole 203, both ends of which pass through the fiber optic mounting plane 202, and an optical fiber is installed in the fiber optic mounting hole 203.

[0029] The fiber mounting hole 203 has two ends that pass through the fiber mounting plane 202. In other words, the fiber mounting hole 203 is a through hole structure that passes through the fiber mounting plane 202 and is open at both ends, so that the fiber can be completely inserted and form an effective inductive association with the wear surface of the middle plate.

[0030] The number of rows, diameter, spacing, quantity, and arrangement of the fiber optic mounting holes 203 can be determined according to actual measurement requirements.

[0031] Specifically, the key parameters of the fiber mounting hole 203 can be flexibly adapted according to actual testing needs. The diameter of the fiber mounting hole 203 must be precisely matched with the outer diameter of the fiber to be installed to ensure that the fiber is not loose or displaced after installation, while leaving a slight gap to facilitate subsequent glue injection and fixation. The spacing between adjacent fiber mounting holes 203, the number of holes, and the arrangement of holes can be adjusted according to the testing accuracy requirements. The number of holes on a single fiber arrangement rod 201 can be set according to the testing length requirements of the middle plate to ensure coverage of the critical areas of the middle plate that are prone to wear.

[0032] During fiber optic installation, a single fiber is threaded through the fiber optic mounting hole 203, with both ends extending from the side openings of the fiber optic mounting plane 202. After the fiber is threaded, a special sealant is injected into the fiber optic mounting hole 203. The sealant fills the gaps in the hole and wraps around the outer wall of the fiber. This serves two purposes: firstly, it fixes and limits the fiber, preventing displacement during vibration or wear of the middle plate; secondly, it forms a protective layer, preventing dust and moisture from the mining environment from entering the hole and causing fiber optic aging and damage. After installation, the fiber axis is parallel to the upper and lower end faces of the middle plate, and the outer wall of the fiber is tightly fitted to the inner wall of the fiber optic mounting hole 203. When wear occurs on the middle plate, the worn surface will gradually approach and cut off the fiber at the corresponding position. The wear depth and location information are accurately fed back through changes in the on / off state of the optical signal.

[0033] In another embodiment, at least two rows of fiber mounting holes 203 are provided along the axial direction of the fiber optic arrangement rod 201, and the two rows of fiber mounting holes 203 are arranged alternately. This avoids mutual interference between adjacent rows of fibers and enables full coverage detection of the wear area.

[0034] Among them, the optical fiber mounting holes 203 are arranged in multiple staggered rows along the length of the optical fiber mounting plane 202. Each row of optical fiber mounting holes 203 is evenly distributed along the vertical direction of the optical fiber mounting plane 202. Through the staggered arrangement design, the density of detection points per unit length is greatly increased without increasing the space occupied by the mounting plane.

[0035] In another embodiment, the test rod further includes a base 204 and a limiting block 205. The fiber optic arrangement rod 201 is disposed on the base 204, and the limiting block 205 is disposed on the base 204. One side of the limiting block 205 is attached to the side wall of the fiber optic arrangement rod 201. The limiting block 205 is connected to the protective housing 101 so that the fiber optic arrangement rod 201 is encapsulated in the protective housing 101.

[0036] The base 204 serves as the supporting foundation for the test rod and is made of wear-resistant material. A limiting block 205, integrally formed with the base 204, is provided on the base 204. The upper surface of the limiting block 205 and the upper surface of the base 204 form a height difference, allowing the limiting block 205 to both enable a detachable connection between the protective shell 101 and the test rod, and to limit the axial position of the protective shell 101. This ensures that after assembly, the upper surface of the test rod fits snugly against the inner surface of the cavity of the protective shell 101, guaranteeing relative stability during installation.

[0037] In another embodiment, a connecting block 102 is provided at the open end of the protective housing 101. The connecting block 102 abuts against the limiting block 205, and the portion of the protective housing 101 without the connecting block 102 abuts against the base 204, so that the fiber optic arrangement rod 201 is encapsulated within the protective housing 101. The connecting block 102 is provided to mount the protective housing 101 onto the base 204 of the test rod, so that the test rod can be encapsulated within the protective housing 101.

[0038] The connecting block 102 has the same shape as the limiting block 205 so that the two form a continuous surface structure after installation.

[0039] In another embodiment, the protective housing 101 has an open end sidewall provided with an optical fiber inlet and an optical fiber outlet 103 arranged opposite to each other, and the optical fiber inlet and the optical fiber outlet 103 are respectively arranged corresponding to the optical fiber mounting plane 202.

[0040] The fiber optic inlet and outlet 103 are respectively arranged corresponding to the fiber optic mounting plane 202. The fiber optic inlet and outlet 103 correspond one-to-one with the fiber optic mounting planes 202 on both sides of the fiber optic arrangement rod 201. In fact, the left fiber optic inlet faces the left fiber optic mounting plane 202, and the right fiber optic outlet 103 faces the right fiber optic mounting plane 202, ensuring that the fiber optic cable installed in each column of fiber optic mounting holes 203 can pass through smoothly.

[0041] After the optical fiber enters from the left optical fiber inlet, it is arranged horizontally along the optical fiber mounting holes 203 on the left optical fiber mounting plane 202, passing through the staggered optical fiber mounting holes 203 in sequence, and finally exiting from the right optical fiber outlet 103. The optical fiber does not need to be offset laterally throughout the entire path and always stays in contact with the optical fiber mounting plane 202. This ensures the parallelism and accuracy of the optical fiber arrangement, and keeps the sensing distance between the optical fiber and the wear surface of the middle plate consistent, thereby improving the accuracy of the detection data.

[0042] In another embodiment, both the fiber optic inlet and outlet 103 have rounded transition structures at their edges. The radius of curvature of the rounded transition structure is not less than the diameter of the fiber, which is used to prevent the fiber from being scratched or damaged by the edges of the fiber optic inlet and outlet 103 during installation or routing.

[0043] In another embodiment, the routing channel is filled with encapsulating colloid, which encapsulates and fixes the optical fiber located within the routing channel. The encapsulating colloid bonds the optical fiber arrangement rod 201 to the inner wall of the protective shell 101 into a single structure. The cured encapsulating colloid forms a dense protective layer, completely isolating the routing channel from the external environment, preventing coal dust, moisture, and corrosive gases in the mine from intruding into the channel, avoiding aging, wear, or short circuits of the optical fiber sheath, and extending the service life of the optical fiber.

[0044] In another embodiment, the protective housing 101 is made of a wear-resistant material to extend the service life of the detection module.

[0045] In a second aspect of this application, a scraper conveyor is provided, including a detection module as described above, and a central trough, which includes a central plate, and the detection module is mounted on the central plate.

[0046] The compact structure of the test bar effectively reduces the limitations of its installation location, enabling it to effectively detect wear on the middle plate.

[0047] The detection module utilizes a protective housing 101 to protect the installed optical fibers. The fiber mounting holes 203 on the test rod address the difficulties in fiber installation and low arrangement accuracy. Furthermore, the assembly of the protective housing 101 and the test rod creates vertical routing channels on both sides, ensuring parallel fiber arrangement on both sides of the mounting holes 203 and preventing crosstalk interference after fiber wear and breakage. This solves problems such as difficulty in pre-embedding optical fibers at the test point, low fiber arrangement accuracy, and easy interference between worn fibers when using the on / off state of the internal optical signal as the detection signal for mid-plate wear.

[0048] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0049] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
