Description

Technical Field

[0001] The present invention relates to the technical field of scraper detection, in particular to a scraper state detection device for a scraper conveyor. Background Art

[0002] Scraper conveyor is a continuous conveying equipment widely used in mining, metallurgy, coal and other industries. It is mainly used for transporting ore, coal and other materials.

[0003] Scraper conveyors use chains to drive scrapers within the conveyor trough, thereby conveying materials. However, during long-term operation, scrapers are prone to breakage, deformation, or detachment due to wear, impact, or overload. If damaged scrapers are not promptly inspected and replaced, this can lead to decreased conveying efficiency, equipment damage, and even safety accidents.

[0004] At present, the status detection of scraper conveyors mainly relies on manual inspections or fixed-point monitoring. Manual inspections are inefficient and it is difficult to detect scraper faults in real time. Fixed points are restricted in installation location and detection range, and cannot fully cover the operating status of scraper conveyors. In addition, the working environment of scraper conveyors is harsh, and dust, debris, etc. are easily attached to the detection device, affecting the accuracy of the detection device and even leading to false detection or missed detection.

[0060] Technical effects and advantages of the present invention:

[0061] (1) The present invention detects the scrapers in the scraper conveyor body through the detection mechanism, so that the damaged scrapers can be replaced in time. The detection mechanism can detect the scrapers at multiple angles through the setting of the adjustment mechanism, thereby improving the accuracy of the detection. The detection mechanism can be moved by the moving mechanism to avoid the detection mechanism being always located in the scraper conveyor body and being affected by the dust in the scraper conveyor body. At the same time, the dust attached to the detection mechanism can be cleaned through the setting of the cleaning mechanism and the blowing mechanism to avoid affecting the operation of the detection mechanism.

[0062] (2) The present invention utilizes the setting of the dust blowing mechanism. The air pump blows air into the movable chamber located below the first piston plate, so that the first piston plate can move up. The movement of the first piston plate drives the first movable rod to move up, so that the connecting box can rotate clockwise. When the air pump draws air into the movable chamber, the first piston plate can be moved down under the action of negative pressure, thereby causing the first movable rod to move down, thereby causing the connecting box to rotate counterclockwise. When the first piston plate moves up, the air above the first piston plate passes through the first one-way valve into the exhaust pipe, and then into the exhaust chamber, and finally blows out through the exhaust hole. The wind blown out from the exhaust hole directly blows onto the surface of the protective glass, so that the protective glass can be cleaned during the adjustment process. When the first piston plate moves down, there will be a negative pressure trend above the first piston plate, so that the exhaust hole will be exhausted. The sucked air passes through the exhaust chamber, the exhaust pipe and the second one-way valve in turn into the movable chamber, thereby maintaining the air pressure balance in the movable chamber. At the same time, during the process of exhausting the air through the exhaust hole, the air flow moves on the surface of the protective glass, which can also achieve the cleaning effect.

[0063] (3) The present invention utilizes the setting of the inflation mechanism and the blocking mechanism. The upper half of the turntable is cam-shaped, and the lower half of the turntable is disc-shaped. When the turntable rotates, the cam groove limits the guide of the card shaft, and the second piston plate can be driven to move back and forth in the sliding cavity under the connection of the connecting block. At this time, since the air outlet is blocked by the blocking mechanism, the air continuously enters the air storage chamber through the third one-way valve. Since the air in the air storage chamber cannot be discharged, the air can squeeze the third piston plate, so that the third piston plate squeezes the first spring upward, and the air stored in the air storage chamber increases. When the blowing mechanism needs to work, the blocking mechanism is unlocked. At this time, under the elastic force of the first spring, the third piston plate is moved downward, and the air in the air storage chamber can be discharged through the air outlet, so that the blowing mechanism can work. At the same time, the turntable is directly fixed on the second rotating shaft, so that the cleaning mechanism works When the air is stored in the air storage chamber, the sealing mechanism works. When the air-charging mechanism and the cleaning mechanism are not working, the turntable stops rotating. Under the elastic action of the second spring, the second movable rod moves in the opposite direction and resets, and under the elastic force of the third spring, the sealing plate drives the movable bar to move in the opposite direction and resets, so that the air outlet is connected, and the blowing mechanism works.

When the detection mechanism is finished, the detection mechanism is in the fixed box 201. Flip and move upward so that the top of the protective glass 303 contacts the bristles 604, and then the second servo motor 606 starts to work, driving the second rotating shaft 602 to rotate. The rotation of the bar-shaped second rotating shaft 602 can make the bristles 604 clean the top of the protective glass 303. During the cleaning process, the dust is blown away from the protective glass 303 by the blowing mechanism. At this time, the dust floating in the fixed box 201 can be extracted under the operation of the dust extractor 209.

The third one-way valve 703 is inserted into the inner wall of the air storage chamber 701. The air in the air storage chamber 701 is blown out through the air outlet 702 and can be blown toward the protective glass 303, thereby blowing up the dust attached to the protective glass 303 and swept by the brush 604, making it convenient for the vacuum cleaner 209 to extract dust.

[0084] Among them, the inflation mechanism includes a second piston plate 705, a rotating disk 707, a connecting plate 710 and a third piston plate 712.

The upper half of the turntable 707 is arranged in a cam shape. The lower half of the disc 7 is set. When the turntable 707 rotates, the cam groove 708 limits the guide of the card shaft 711, and the second piston plate 705 can be driven to move back and forth in the sliding cavity 704 under the connection of the connecting block 709. At this time, since the air outlet 702 is blocked by the blocking mechanism, the air continuously enters the air storage chamber 701 through the third one-way valve 703. Since the air in the air storage chamber 701 cannot be discharged, the air can squeeze the third piston plate 712, so that the third piston plate 712 is opened. The plug plate 712 squeezes the first spring 713 to move upward, thereby increasing the air stored in the air storage chamber 701. When the blowing mechanism needs to work, the blocking mechanism is unlocked. At this time, under the elastic force of the first spring 713, the third piston plate 712 moves downward, so that the air in the air storage chamber 701 can be discharged through the air outlet 702, allowing the blowing mechanism to work. At the same time, the turntable 707 is directly fixed on the second rotating shaft 602, so that the cleaning mechanism can collect air while the blowing mechanism is working.

However, when the second rotating shaft 602 rotates to drive the cleaning mechanism and the turntable 707 to work, the second movable rod 806 will overcome the elastic effect of the third spring 814 under the action of centrifugal force, so that the second movable rod 806 moves toward the outside of the turntable 707, thereby causing the roller 808 to squeeze the movable bar 804, causing the movable bar 804 to move, and the movable bar 804 moves to drive the blocking plate 802 The blocking plate 802 moves, driving the limit block 813 to move. The limit block 813 moves to compress the third spring 814 until the blocking plate 802 passes through the air outlet 702, thereby blocking the air outlet 702. In this way, the blocking mechanism works during the air storage process in the air storage chamber 701. When the inflating mechanism and the cleaning mechanism are not working, the turntable 707 stops rotating. Under the elastic action of the second spring 811, the second movable rod 806 moves in the opposite direction and resets. Under the elastic force of the third spring 814, the blocking plate 802 drives the movable bar 804 to move in the opposite direction and reset, so that the air outlet 702 is connected, and the blowing mechanism works.Furthermore, multiple sets of second movable rods 806 are provided, and the movable bars 804 are elongated. Furthermore, the first movable slots 801 are lengthened, allowing the blocking plate 802 to move a certain distance after passing through the air outlet 702. This distance prevents the blocking plate 802 from directly separating from the air outlet 702 even if the movable bars 804 return to their original positions during rotation of the turntable 707, thereby improving the stability of the blocking mechanism.
