Description

Technical Field

[0001] This invention belongs to the field of scraper conveyor detection and straightening technology, specifically an automatic straightening device and method for a fully mechanized mining face scraper conveyor. Background Technology

[0002] Scraper conveyors are key conveying equipment widely used in various industries such as coal mining, mining, metallurgy, building materials, and cement. Their basic components include a trough, traction chain, scraper, head drive chain, and tail tension sprocket, enabling them to carry large quantities of material and transport it efficiently over long distances. They are renowned for their low energy consumption and high conveying efficiency, playing a particularly important role in coal production.

[0003] Scraper conveyors not only transport coal but also provide a track for the coal mining machine. Their posture directly affects the machine's trajectory and the pushing accuracy of the hydraulic supports. During operation in a fully mechanized mining face, scraper conveyors must withstand complex environmental conditions including pressure, impact, bending, and friction, and are also subject to the skill level of the on-site workers. Improper operation can lead to insufficient straightness of the conveyor, resulting in scraper chain breakage, central trough wear, and machine deformation. In severe cases, this can even disrupt the entire mining process, significantly impacting production efficiency and posing significant safety hazards. Therefore, straightening is essential when using scraper conveyors.

[0004] However, most existing straightening methods for scraper conveyors require a large amount of manual labor, resulting in low straightening efficiency and accuracy. Furthermore, existing straightening devices adjust in only one direction, leading to poor straightening effects.

[0015] This invention also provides an automatic straightening method for a fully mechanized mining face scraper conveyor, based on the automatic straightening device for a fully mechanized mining face scraper conveyor as described above, comprising the following steps: Step 1: The staff installs the entire device in sequence according to the requirements. At this time, the staff controls multiple upper support rods, rear support rods and front support rods to make the top support frame, front support frame, rear support frame and lower support frame fit tightly against the coal mine roadway, thereby ensuring the safety of the entire device. At this time, the support block is in close contact with the roadway floor. Step 2: The controller further controls the detection head motor to work, thereby driving the locking tube to rotate, so that each locking head at the top is in close contact with the locking head moving rail, thereby driving the positioning tube to rotate, thus making multiple corner detectors horizontal. At this time, due to the action of the connecting ring and the detection head, the angle sensor can display the angle between two adjacent detection rods, so that the controller can detect the angle between two detection tubes through the detection plate. Step 3: If there is an angle between the two, the second controller controls the extension and retraction of the second support block, thereby driving the second connecting plate to move back and forth, and thus driving the second conveyor frame to move back and forth until the angle between the two detection tubes is zero. Then, the two controllers control the two detection head motors to reverse the locking tube, thereby making the bend detector vertical. At this time, the controller can detect the height difference between the two detection tubes through the cooperation of two angle sensors, thereby detecting the vertical angle between the two detection tubes. Then, the two controllers control the extension and retraction of the cleaning rod on the higher side to drive the cleaning plate to move, thereby cleaning the aisle at the bottom of the conveyor frame on the higher side, thereby making the conveyor frame on the higher side lower, so that the height of the two detection tubes is consistent. At the same time, the level can be used to detect whether the front and rear ends of the conveyor frame are horizontal, and then the cleaning angle can be adjusted by the cleaning rod reversing motor to ensure that the conveyor frame is horizontal. Step 4: After the angle of the second conveyor frame is straightened, the second controller controls the extension of the second stabilizer rod, thereby driving the second stabilizer head to insert into the ground, thus preventing the second conveyor frame from moving. At this time, the second controller controls the second top support frame, the second front support frame, the second rear support frame, and the second lower support frame to not contact the coal mine roadway. Further, the second controller controls the second set of reversing motors to work, thereby driving the second set of rollers to support the second support block, thus facilitating the movement of the second support block. At this time, due to the distance between the connector and the stabilizer plate, the moving rod can be moved up and down easily. Step 5: The second controller further controls the extension and retraction of the second moving rod, thereby driving the second support block to move back and forth, thus changing the distance between the second support block and the second conveyor frame. This process is repeated until the straightening of multiple conveyor frames is completed.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) This device can generate an angle between the bend detector and the detector rod by rotating the detector rod, so that the angle between the two detector tubes can be detected by the angle sensor, which facilitates straightening. At the same time, the positioning ring of the detector head can ensure that the detector head can only rotate in one direction, thus ensuring the accuracy of the detection. At the same time, the detector head motor can drive the main gear of the detector head to rotate, which in turn drives the secondary gear of the detector head to rotate, which in turn drives the locking tube to rotate, which in turn drives the positioning tube to rotate, thus enabling the detection of different directions of the two detector tubes, thus ensuring that the axes of the two detector tubes are the same, thus ensuring the accuracy of straightening, and improving the straightening efficiency, thus ensuring the straightening efficiency of the two detector tubes. (2) This device can drive the main reversing gear to rotate through the reversing motor, thereby driving the secondary reversing gear to rotate, thereby driving the reversing shaft to rotate, thereby causing the connecting rod to rotate, thereby causing the roller to support the support block to lift off the ground, thus facilitating the movement of the support block, thus facilitating the movement of the entire device, thereby preventing the support block from scraping against the coal mine roadway, thereby improving the service life of the equipment, and at the same time improving the automation level of the equipment, thereby saving labor. (3) This device can move the stabilizer head up and down by extending and retracting the stabilizer rod, thereby positioning the conveyor frame and fixing the straightened conveyor frame, thus facilitating the movement of the support block. At the same time, this device can support the coal mine roadway by cooperating with the top support frame, front support frame, rear support frame and lower support frame, thereby ensuring the safety of the workers. (4) This device can move the cleaning plate by extending and retracting the cleaning rod, thereby cleaning the coal dust at the bottom of the conveyor frame. At the same time, the cleaning plate motor can drive the main gear of the cleaning plate to rotate, thereby driving the secondary gear of the cleaning plate to rotate, thereby driving the cleaning shaft to rotate, thereby changing the cleaning depth of the cleaning plate and improving the cleaning efficiency. At the same time, this device can drive the fixed plate to rotate by the cleaning rod reversing motor, thereby driving the cleaning shaft positioning plate to reverse, thereby making the cleaning plate reversible, thus cleaning at different angles, thereby ensuring the cleaning effect, thereby ensuring the level of the conveyor frame and ensuring that the axes of the two detection tubes are the same, thereby ensuring that the two conveyor frames are parallel, thereby ensuring the straightening effect. (5) This device can move the conveyor frame by extending and retracting the moving rod, which makes it easy to straighten. At the same time, due to the function of the connector and the connecting plate, the moving rod can move up and down, which makes it easy for the support block to rise, thus ensuring the moving effect of the support block and thus ensuring the moving efficiency of the whole device.

[0025] This embodiment of an automatic straightening method for a fully mechanized mining face scraper conveyor, based on the aforementioned automatic straightening device for a fully mechanized mining face scraper conveyor, includes the following steps: Step 1: The staff installs the entire device in sequence according to the requirements. At this time, the staff controls multiple upper support rods 204, rear support rods 205 and front support rods 206 to make the top support frame 2, front support frame 201, rear support frame 202 and lower support frame 203 fit tightly with the coal mine roadway, thereby ensuring the safety of the entire device. At this time, the support block 4 is in close contact with the roadway ground. Step 2: The controller 305 further controls the detection head motor 906 to work, thereby driving the locking tube 902 to rotate, so that each locking head 910 at the top is in close contact with the locking head moving rail 911, thereby driving the positioning tube 9 to rotate, so that the multiple corner detectors 8 are horizontal. At this time, due to the action of the connecting ring 804 and the detection head 806, the angle sensor 802 can display the included angle between two adjacent detection rods 801, so that the controller 305 can detect the included angle between two detection tubes 3 through the detection plate 805; Step 3: If there is an angle between the two, the second controller 305 controls the extension and retraction of the second support block 4, thereby driving the second connecting plate 304 to move back and forth, thereby driving the second conveyor frame 1 to move back and forth until the angle between the two detection tubes 3 is zero. Further, the two controllers 305 control the two detection head motors 906 to reverse the locking tube 902, thereby making the angle detector 8 vertical. At this time, the controller 305 can detect the height difference between the two detection tubes 3 through the cooperation of the two angle sensors 802, thereby detecting the angle between the two detection tubes 3 in the vertical direction. Further, the two controllers 305 control the extension and retraction of the cleaning rod 705 on the higher side to drive the cleaning plate 7 to move, thereby cleaning the tunnel at the bottom of the conveyor frame 1 on the higher side, thereby causing the conveyor frame 1 on the higher side to descend, thereby making the two detection tubes 3 at the same height. At the same time, the level 702 can detect whether the front and rear ends of the conveyor frame 1 are horizontal, and then the cleaning angle can be adjusted by the cleaning rod reversing motor 703 to ensure that the conveyor frame 1 is horizontal. Step 4: After the angle of the second conveyor frame 1 is straightened, the second controller 305 controls the second stabilizer 601 to extend, thereby driving the second stabilizer head 6 to insert into the ground, thus preventing the second conveyor frame 1 from moving. At this time, the second controller 305 controls the second top support frame 2, the second front support frame 201, the second rear support frame 202, and the second lower support frame 203 to not contact the coal mine roadway. Further, the second controller 305 controls the second set of reversing motors 507 to work, thereby driving the second set of rollers 503 to support the second support block 4, thus facilitating the movement of the second support block 4. At this time, the distance between the connector 402 and the stabilizer plate 303 allows the moving rod 401 to move up and down easily. Step 5: The second controller 305 further controls the extension and retraction of the second moving rod 401, thereby driving the second support block 4 to move back and forth, thereby changing the distance between the second support block 4 and the second conveyor frame 1, and so on until the straightening work of multiple conveyor frames 1 is completed.
