Description

Technical Field

[0001] The invention relates to the field of measurement technology, and in particular to a continuous measurement device for belt deviation angle based on the Hall principle. Background Art

[0002] In industrial automation and material conveying systems, belt conveyors, as an important transmission equipment, are widely used in various production lines and logistics systems. However, during the operation of the belt, due to factors such as load changes, uneven belt tension, roller wear or installation errors, the belt often deviates. Belt deviation not only affects the stability and accuracy of material transmission, but may also cause equipment damage and safety hazards. Therefore, continuous monitoring and precise measurement of the belt deviation angle is of great significance to ensure the normal operation of the production line and the reliability of material transportation.

[0003] When using the above-mentioned device, although the automatic shut-off function can be realized when the belt is offset, the traditional deviation sensor is limited to the on-off control of the belt and cannot accurately measure the angle of the belt deviation. In addition, the automatic reset function of the traditional vertical rod is not effective, resulting in the vertical rod still remaining in the offset state after the belt is reset to the initial position, which not only hinders the normal operation of the equipment, but also is not conducive to the rotational deviation of the vertical rod. As the inclination angle of the vertical rod increases, the friction force on the tension belt also increases, further affecting the normal deviation measurement of the equipment. Therefore, a continuous measurement device for the belt deviation angle based on the Hall principle is proposed. Summary of the invention

[0015] The present invention has the following beneficial effects:

[0016] 1. The continuous measuring device for belt deviation angle based on the Hall principle, when the belt body deviates, the belt body will exert pressure on the vertical rod, causing the vertical rod to rotate on the top of the connecting rod. Subsequently, the connecting rod will rotate slightly on the outer wall of the mounting shell after being squeezed. When the connecting rod tilts, it will send a signal, causing the device to shut down. At the same time, when the rotating plate rotates, it will drive the connecting plate to rotate together. The connecting plate will drive the induction magnet to rotate during the rotation process. When the induction head detects the rotation of the induction magnet, it will send a corresponding angle electrical signal to the device. In addition, the induction magnet and the induction head can also perform precise testing of analog quantities simultaneously, such as carefully measuring the continuous changing data such as the deviation amplitude, running speed and vibration frequency of the belt, so as to provide comprehensive data support for the operation status of the equipment. Thanks to the high precision and stability of the induction magnet and the induction head themselves, the accuracy and reliability of the test data have been significantly improved, effectively reducing the false alarm and missed alarm caused by sensor failure, which provides a solid and comprehensive technical guarantee for the stable and efficient operation of the belt conveyor, further improves the safety and service life of the equipment, and realizes the function of automatically detecting the switch quantity and analog offset.

[0017] 2. The continuous measurement device for belt deviation angle based on the Hall principle will cause rotational deviation when the monitoring component is subjected to pressure. During this process, the deviation and rotation of the monitoring component will drive the rotating block 1 to rotate together. As the rotating block 1 rotates, it will exert pressure on the transmission belt, so that the transmission belt drives the rotating block 2 to rotate on the top of the support rod. At the same time, in the process of driving the rotating block 2 to rotate, a pulling force will be applied to the rotating block 2, causing the rotating block 2 to drive the support rod and the ball to rotate on the inner wall of the top of the bottom block. The limiting effect of the sliding block, the arc plate and the limiting groove ensures that the support rod and the ball can rotate. When the support rod rotates, it can only drive the sliding block to slide on the inner wall of the limiting groove. When the support rod rotates, it will also drive the pressure rod and the limiting rod to rotate on the inner wall of the fixed plate, so that the pressure rod drives the cylinder to rotate on the inner wall of the connecting block 2 when it rotates, and pushes the pressure plate to drive the rotating column to rotate on the inner wall of the fixed block. When the pressure plate and the pressure rod rotate, tensioning force will be applied to the arc spring 2. Once the belt body is adjusted to the appropriate position, the monitoring component will stop rotating, thereby canceling the tensioning limit on the arc spring 2. The arc spring 2 will then use its elastic potential energy to release and drive the pressure rod to rebound. During the rebound process, the pressure rod will push the support rod to rotate, so that the support rod drives the rotating block 2 to apply pressure to the vertical rod, causing the vertical rod to automatically reset. In addition, the shock absorber absorbs the elastic force of the arc spring 2 to ensure that the vertical rod can be smoothly reset. At the same time, when the monitoring component is under pressure and deflected, it will drive the rotating block 3 to rotate on the top of the circular block. During the rotation process, the rotating block 3 will drive the connecting block 1 to rotate, and then the connecting block 1 will drive the rotating rod, steel ball and arc spring 1 to rotate. When the connecting block 1 rotates, it will also push the steel ball to knock against the outer wall of the steel plate, causing the steel plate to sound an alarm. When the plates collide, it will drive the rotating rod to rotate on the inner wall of the connecting block 1, and the rotating rod will apply pressure to the arc spring 1 when rotating. As the rotating rod rotates, it will also drive the steel ball to rotate on the inner wall of the round block. When the steel ball stops knocking on the steel plate, the elastic potential energy of the arc spring 1 will be released, causing the arc spring 1 to drive the rotating rod to rebound, thereby allowing the steel ball to continuously knock on multiple steel plates in the inner wall of the round block. Therefore, as long as the monitoring component is offset, the alarm will continue to sound, and when the monitoring component returns to its original position, the alarm will stop. In this way, the staff can check the belt body through the alarm sound.

[0018] 3. The continuous measurement device for belt deviation angle based on the Hall principle, when the monitoring component faces pressure, the electromagnet is powered off, causing the magnetic block to lose its attraction and canceling the limit on spring three. At this time, spring three uses its elastic potential energy to release and drive the magnetic block to rebound. The magnetic block then drives the winding wheel and the block to rotate in the inner wall of the square groove. The winding wheel causes the wire rope to wind during the rotation, and the wire rope pushes the piston to move in the inner wall of the gas collecting pipe when winding. When the wire rope is wound, it will draw out the air on the inner wall of the gas transmission pipe. When the piston moves to the notch of the gas collecting pipe, the electromagnet is powered on again, and the opposite attraction causes the electromagnet and the magnetic block to attract each other, causing the magnetic block to stick to the outer wall of the electromagnet. When the block moves out from the inner wall of the square groove, the limit on the winding wheel and the torsion spring 2 is cancelled, and the elastic potential energy of the torsion spring 2 is released, so that it drives the wire rope to unwind. The wire rope exerts pressure on the piston, pushing it to move in the inner wall of the gas collecting pipe, and then pushing the gas on the inner wall of the gas transmission pipe. Since the gas collecting pipe and the inner wall of the gas transmission pipe form a sealed space, the piston will exert pressure on the sealing block after pushing the gas, so that it moves in the groove of the gas transmission pipe. During the movement, the sealing block drives the extension plate and the pressure rod to exert pressure on the support rod to assist its rotation, thereby avoiding the rotating block 1 from exerting pressure on the transmission belt when rotating and deflecting, reducing friction, thereby reducing the deflection effect of the vertical stick, and achieving more accurate detection of the monitoring component.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 - Fig.11A continuous measuring device for belt deviation angle based on the Hall principle comprises a supporting base 1, a circular arc plate 14 and a bottom block 8 are fixedly mounted on the top of the supporting base 1, a monitoring component 5, a reset component 12 and a negative pressure component 13 are respectively arranged on the top of the supporting base 1, a supporting plate 2 is arranged on the outer wall of the supporting base 1, a supporting rod 3 is rotatably connected to the inner wall of the supporting plate 2, a belt body 4 is arranged on the outer wall of the supporting rod 3, a rotating block 6 is fixedly mounted on the outer wall of the monitoring component 5, a rotating groove 16 is opened on the top of the circular arc plate 14, a round ball 9 is rotatably connected to the inner wall of the rotating groove 16, and a supporting rod 10 is fixedly mounted on the outer wall of the round ball 9. One end, the other end of the support rod 10 is fixedly equipped with a rotating block 2 11, the inner wall of the rotating block 16 is rotatably connected with a transmission belt 7, the outer wall of the arc plate 14 is provided with a limiting groove 15, the outer wall of the monitoring component 5 is respectively provided with a round block 17 and a rotating block 3 18, the inner wall of the round block 17 is fixedly equipped with a steel plate 19, the outer wall of the rotating block 3 18 is fixedly equipped with a connecting block 1 20, the inner wall of the connecting block 1 20 is rotatably connected to one end of a rotating rod 21, the other end of the rotating rod 21 is fixedly equipped with a steel ball 22, the outer wall of the connecting block 1 20 is fixedly equipped with an arc spring 1 23, and the outer wall of the support rod 10 is fixedly equipped with a sliding block 24.

[0036] In the above structure, when the monitoring component 5 is deflected by pressure, the rotating block 3 18 will be prompted to rotate, thereby driving the rotating block 3 18 to rotate on the top of the round block 17. As the rotating block 3 18 rotates, the connecting block 1 20 will also rotate accordingly, thereby pushing the rotating rod 21, the steel ball 22 and the arc spring 1 23 to rotate accordingly. During the rotation of the connecting block 1 20, the steel ball 22 will hit the outer wall of the steel plate 19, causing the steel plate 19 to sound an alarm. At the same time, the steel ball 22 will drive the rotating rod 21 to rotate in the inner wall of the connecting block 1 20 during the collision with the steel plate 19, and the rotating rod 21 During rotation, pressure is applied to the arc spring 23, and the rotation of the rotating rod 21 also drives the steel ball 22 to rotate in the inner wall of the round block 17. When the steel ball 22 stops hitting the steel plate 19, the elastic potential energy of the arc spring 23 is released, causing the arc spring 23 to push the rotating rod 21 to rebound, so that the steel ball 22 can continuously hit the multiple steel plates 19 in the inner wall of the round block 17. Therefore, as long as the monitoring component 5 continues to be offset, the alarm will continue to sound. Once the monitoring component 5 returns to its original position, the alarm will stop. In this way, the staff can check the condition of the belt body 4 through the alarm sound.

[0037] In a preferred embodiment: the monitoring component 5 includes a mounting shell 501, the outer wall of the mounting shell 501 is provided with a mounting shell 502, the inner wall of the mounting shell 502 is fixedly equipped with an inductive magnetic head 507, the outer wall of the mounting shell 501 is rotatably connected to a connecting rod 508, the outer wall of the connecting rod 508 is fixedly equipped with a rotating plate 503, the outer wall of the rotating plate 503 is fixedly equipped with a torsion spring 504, the end of the rotating plate 503 away from the connecting rod 508 is fixedly equipped with one end of a connecting plate 505, the other end of the connecting plate 505 is fixedly equipped with an inductive magnet 506, the top of the connecting rod 508 is rotatably connected to a vertical stick 509, the inner wall of the vertical stick 509 is fixedly equipped with a fixing rod 510, and the bottom of the fixing rod 510 is provided with a square groove 511.

[0038] In the above structure, when the belt body 4 is offset, the belt body 4 will apply pressure to the vertical rod 509, causing the vertical rod 509 to rotate at the top of the connecting rod 508. Subsequently, after being squeezed, the connecting rod 508 will slightly rotate on the outer wall of the mounting shell 501. When the connecting rod 508 is tilted, a signal will be sent, causing the device to automatically shut down. At the same time, when the rotating plate 503 rotates, it will drive the connecting plate 505 to rotate accordingly. During the rotation of the connecting plate 505, it will cause the induction magnet 506 to start rotating. When the induction head 507 detects that the induction magnet 506 is rotating, it will send a corresponding angle electrical signal to the device. In addition, the induction magnet The inductive magnet 506 and the inductive head 507 can also perform precise tests on analog quantities simultaneously, such as detailed measurements of continuously changing data such as the offset amplitude, operating speed, and vibration frequency of the belt. These data provide comprehensive data support for the operating status of the equipment. Thanks to the high precision and stability of the inductive magnet 506 and the inductive head 507, the accuracy and reliability of the test data have been significantly improved, effectively reducing false alarms and missed alarms caused by sensor failures, which provides a solid and comprehensive technical guarantee for the stable and efficient operation of the belt conveyor, further improves the safety and service life of the equipment, and realizes the function of automatically detecting switching quantities and analog offsets.

[0039] In a preferred embodiment: the reset assembly 12 includes a fixed block 1201, the inner wall of the fixed block 1201 is rotatably connected to a rotating column 1202, the outer wall of the rotating column 1202 is fixedly equipped with one end of a pressure plate 1203, the other end of the pressure plate 1203 is fixedly equipped with a connecting block 1206, the inner wall of the connecting block 1206 is rotatably connected to a cylinder 1207, the outer wall of the cylinder 1207 is fixedly equipped with a pressure rod 1208, the outer wall of the pressure rod 1208 is provided with a fixed plate 1209, the inner wall of the fixed plate 1209 is rotatably connected to a limiting rod 1210, the outer wall of the pressure plate 1203 is fixedly equipped with a shock absorber 1204, and the inner wall of the shock absorber 1204 is rotatably connected to an arc spring 1205.

[0040] In the above structure, when the monitoring component 5 is subjected to pressure, rotational deviation will occur. During this process, the rotation and deviation of the monitoring component 5 will drive the rotating block 1 6 to rotate accordingly, thereby applying pressure to the transmission belt 7. As the transmission belt 7 rotates, it will drive the rotating block 2 11 to rotate at the top of the support rod 10, and apply tension to it while driving the rotating block 2 11 to rotate. As a result, the rotating block 2 11 will guide the support rod 10 and the ball 9 to rotate on the inner wall of the rotating groove 16 at the top of the bottom block 8. At the same time, through the coordinated action of the sliding block 24, the arc plate 14 and the limiting groove 15, the support rod 10 is limited to ensure that it can only drive the sliding block 24 to slide on the inner wall of the limiting groove 15 when it rotates. As the support rod 10 rotates, it will guide the pressure rod 1208 and the limiting rod 1210 to rotate on the inner wall of the fixed plate 1209, thereby The pressure rod 1208 drives the cylinder 1207 to rotate on the inner wall of the connecting block 1206, and the pressure plate 1203 drives the rotating column 1202 to rotate on the inner wall of the fixed block 1201. During the rotation of the pressure plate 1203 and the pressure rod 1208, a tensioning force will be applied to the arc spring 1205. When the belt body 4 is adjusted to the appropriate position, the monitoring component 5 will stop rotating, and the restriction on the arc spring 1205 will be cancelled. At this time, the arc spring 1205 will use its stored elastic potential energy to release and drive the pressure rod 1208 to rebound. As the pressure rod 1208 rebounds, it will guide the support rod 10 to apply pressure to the vertical stick 509, so that the vertical stick 509 can automatically reset. In addition, the elastic force of the arc spring 1205 is absorbed by the shock absorber 1204 to ensure that the vertical stick 509 can automatically reset smoothly.

[0041] In a preferred embodiment, the negative pressure assembly 13 includes a fixed shell 1301, the inner wall of the fixed shell 1301 is fixedly equipped with an electromagnet 1302, the inner wall of the fixed shell 1301 is fixedly equipped with one end of a spring 3 1303, the other end of the spring 3 1303 is fixedly equipped with a magnetic block 1304, the outer wall of the magnetic block 1304 is rotatably equipped with a winding wheel 1305, the outer wall of the winding wheel 1305 is fixedly equipped with one end of a torsion spring 2 1315, the other end of the torsion spring 2 1315 is fixedly equipped with one end of a steel wire rope 1306, and the other end of the steel wire rope 1306 is fixedly equipped with Equipped with a piston 1308, a block 1307 is fixedly installed on the top of the outer wall of the winding wheel 1305, a mounting block 1309 is provided on the outer wall of the wire rope 1306, an air collecting pipe 1310 is fixedly installed on the inner wall of the mounting block 1309, an air supply pipe 1311 is fixedly installed on the end of the air collecting pipe 1310 away from the wire rope 1306, a sealing block 1312 is slidably connected to the inner wall of the end of the air supply pipe 1311 away from the air collecting pipe 1310, an extension plate 1313 is fixedly installed on the outer wall of the sealing block 1312, and a pressure rod 1314 is fixedly installed on the outer wall of the extension plate 1313.

[0042] In the above structure, when the monitoring component 5 is under pressure, the electromagnet 1302 is powered off, causing the magnetic block 1304 to lose its attraction, and the restriction on the spring three 1303 is cancelled, so that the spring three 1303 releases its elastic potential energy, thereby driving the magnetic block 1304 to rebound. The rebound action of the magnetic block 1304 drives the winding wheel 1305 and the block 1307 to rotate in the inner wall of the square groove 511. The winding wheel 1305 will cause the steel wire rope 110 to rotate during the rotation process. 306 is wound, and the steel wire rope 1306 pushes the piston 1308 to move in the inner wall of the gas collecting pipe 1310 when winding. When the steel wire rope 1306 is wound, it will draw out the air in the inner wall of the gas delivery pipe 1311. When the piston 1308 moves to the notch of the gas collecting pipe 1310, the electromagnet 1302 is energized again, and the electromagnet 1302 and the magnetic block 1304 attract each other due to the attraction of opposite charges, so that the magnetic block 1304 fits tightly with the outer wall of the electromagnet 1302. When 1307 moves out from the inner wall of the square groove 511, the restrictions on the reel 1305 and the second torsion spring 1315 will be cancelled, and the elastic potential energy of the second torsion spring 1315 will be released. During the release process, the second torsion spring 1315 will drive the steel wire rope 1306 to unwind, exerting pressure on the piston 1308. When the piston 1308 moves in the inner wall of the gas collecting pipe 1310, it will push the gas on the inner wall of the gas transmission pipe 1311. Since the inner walls of the gas collecting pipe 1310 and the gas transmission pipe 1311 form a sealed space, When the piston 1308 pushes the gas, it will apply pressure to the sealing block 1312, causing the sealing block 1312 to move in the groove of the gas pipe 1311. During the movement, the sealing block 1312 will drive the extension plate 1313 and the pressure rod 1314 to apply pressure to the support rod 10, thereby assisting the support rod 10 to rotate, and preventing the rotating block 1308 from applying pressure to the transmission belt 7 when rotating and deflecting, thereby reducing the friction between the transmission belt 7 and the vertical stick 509, and improving the detection effect of the monitoring component 5.

The round block 17 is supported by the connecting rod 508, so that the round block 17 is more stable when placed. The rotating block three 18 is fixed to the outer wall of the vertical stick 509, so that the vertical stick 509 can drive the rotating block three 18 to rotate when it rotates. When the square block 1307 is placed on the inner wall of the square groove 511, there will be no jamming.

[0045] In a preferred embodiment: the arc spring 2 1205 is fixedly assembled with the outer wall of the pressure rod 1208 through the shock absorber 1204, the fixed plate 1209 is fixedly assembled with the outer wall of the support rod 10, the pressure rod 1208 is fixedly assembled with the outer wall of the limit rod 1210, and the fixed block 1201 is fixedly assembled with the top of the support base 1.

[0046] In the above structure, the reset assembly 12 is limited by the support base 1 to avoid instability of the reset assembly 12 during operation, the shock absorber 1204 is used to offset the buffering force of the arc spring 1205, so that the arc spring 1205 will not shake rapidly when releasing the elastic potential energy, the support rod 10 is used to support the fixed plate 1209, and the limiting rod 1210 and the cylinder 1207 are used to limit the pressure rod 1208, so that the pressure rod 1208 will not be detached when rotating.

[0047] In a preferred embodiment: the fixed shell 1301 and the mounting block 1309 are both fixedly assembled to the top of the support base 1, the piston 1308 fits tightly against the inner wall of the gas collecting pipe 1310, the gas supply pipe 1311 is connected to the inner wall of the gas collecting pipe 1310, the sealing block 1312 fits tightly against the inner wall of the gas supply pipe 1311, and the pressure rod 1314 fits against the outer wall of the support rod 10.

[0048] In the above structure, the negative pressure component 13 is limited by the support base 1, so that the negative pressure component 13 will not fall during operation. When the piston 1308 is placed on the inner wall of the gas collecting pipe 1310, the gas in the gas collecting pipe 1310 will be sealed, and the gas will be transported through the gas pipe 1311. When the sealing block 1312 is placed on the inner wall of the gas pipe 1311, the gas inside the gas pipe 1311 will not leak, and the pressure rod 1314 will apply pressure to the support rod 10 when it moves.

[0049] In a preferred embodiment: the arc spring 1 23 is fixedly assembled with the outer wall of the rotating rod 21 , the sliding block 24 is slidably connected with the inner wall of the limiting groove 15 , and the transmission belt 7 is rotatably connected with the inner wall of the rotating block 2 11 .

[0050] In the above structure, the arc spring 23 is limited by connecting block 1 20 and rotating rod 21 to prevent the arc spring 23 from falling when releasing the elastic potential energy. The sliding block 24 and the support rod 10 are limited by the limiting groove 15 to prevent deviation of the support rod 10 when rotating. The rotating block 1 6 drives the transmission belt 7 to rotate when rotating, so that the transmission belt 7 applies force to the inner wall of the rotating block 2 11 when rotating, so that the rotating block 2 11 rotates at the top of the support rod 10.

[0051] In a preferred embodiment: the support rod 3 is perpendicular to the outer wall of the belt body 4 , the ball 9 is matched with the inner wall of the rotating groove 16 , and the fixing rod 510 is rotatably connected to the inner wall of the fixing shell 1301 .

[0052] In the above structure, when the support rod 3 and the outer wall of the belt body 4 are perpendicular to each other, the belt body 4 can achieve a better conveying effect without jamming. When the ball 9 rotates on the inner wall of the rotating groove 16, the rotating groove 16 limits the ball 9 to prevent the ball 9 from detaching from the inner wall of the rotating groove 16 during rotation. The fixed shell 1301 is used to limit the fixed rod 510 to prevent the fixed rod 510 from deviating during rotation.

[0053] In a preferred embodiment, there are two groups of monitoring components 5 , resetting components 12 and negative pressure components 13 , and the two groups of monitoring components 5 , resetting components 12 and negative pressure components 13 are respectively located on the top of the supporting base 1 .

[0054] In the above structure, by using two sets of monitoring components 5, reset components 12 and negative pressure components 13, it is possible to effectively realize all-round detection of the angle deviation on both sides of the belt body 4, ensuring that the belt body 4 can be accurately identified and processed under various circumstances.

[0055] Working principle: When the belt body 4 is offset, the belt body 4 will apply pressure to the vertical rod 509, causing the vertical rod 509 to rotate on the top of the connecting rod 508. After being pressed, the connecting rod 508 will slightly rotate on the outer wall of the mounting shell 501 and send a signal to shut down the device. At the same time, the rotating plate 503 will drive the connecting plate 505 when it rotates, thereby causing the induction magnet 506 to rotate. When the induction head 507 detects that the induction magnet 506 is rotating, it will send an electrical signal of the corresponding angle to the device. The induction magnet 506 and the induction head 507 can also perform precise testing of analog quantities simultaneously, such as measuring the continuous changing data such as the deviation amplitude, running speed and vibration frequency of the belt, to provide comprehensive data support for the operation status of the equipment. The induction magnet 506 and the induction head The high precision and stability of 507 greatly improve the accuracy and reliability of test data, effectively reduce the false alarm and missed alarm caused by sensor failure, provide solid and comprehensive technical guarantee for the stable and efficient operation of the belt conveyor, further improve the safety and service life of the equipment, and realize automatic detection of switch quantity and analog offset. When the monitoring component 5 is under pressure, it will rotate and deflect, and drive the rotating block 1 6 to rotate, so that the rotating block 1 6 puts pressure on the transmission belt 7. When the transmission belt 7 rotates, it will drive the rotating block 2 11 to rotate on the top of the support rod 10, and apply tension to the rotating block 2 11, so that the rotating block 2 11 drives the support rod 10 and the ball 9 to rotate on the inner wall of the rotating groove 16 at the top of the bottom block 8, and the sliding block 24, the arc plate 14 and the limit groove 15 are used to realize The support rod 10 is limited so that the support rod 10 can only drive the sliding block 24 to slide on the inner wall of the limiting groove 15 when it rotates. When the support rod 10 rotates, it will drive the pressure rod 1208 and the limiting rod 1210 to rotate on the inner wall of the fixed plate 1209, so that the pressure rod 1208 drives the cylinder 1207 to rotate on the inner wall of the connecting block 1206, and drives the pressure plate 1203 to drive the rotating column 1202 to rotate on the inner wall of the fixed block 1201. When the pressure plate 1203 and the pressure rod 1208 rotate, the arc spring 1205 is tensioned. When the belt body 4 is adjusted to a good position, the monitoring component 5 stops rotating, canceling the restriction on the arc spring 1205. The arc spring 1205 releases its elastic potential energy to drive the pressure rod 1208 to rebound. The rotation of 208 drives the support rod 10 to apply pressure to the vertical rod 509, so that the vertical rod 509 automatically resets, and the shock absorber 1204 absorbs the elastic force of the arc spring 2 1205, so that the vertical rod 509 is smoothly reset. After being compressed and offset, the monitoring component 5 will drive the rotating block 3 18 to rotate, so that the rotating block 3 18 rotates on the top of the round block 17, and then drives the connecting block 1 20 to rotate, so that the connecting block 1 20 drives the rotating rod 21, the steel ball 22 and the arc spring 1 23 to rotate. When the connecting block 1 20 rotates, it drives the steel ball 22 to knock on the outer wall of the steel plate 19 to sound an alarm. When the steel ball 22 collides with the steel plate 19, it drives the rotating rod 21 to rotate on the inner wall of the connecting block 1 20. When the rotating rod 21 rotates, it will press the arc spring 1 23, so that the arc spring 1 23 drives the rotating rod 21 to rebound.The steel ball 22 continuously strikes the multiple steel plates 19 in the inner wall of the round block 17, continuously sounding the alarm. When the monitoring component 5 is restored, the alarm stops, and the staff can check the belt body 4 through the alarm sound. When the monitoring component 5 is compressed, the electromagnet 1302 is powered off, the magnetic block 1304 loses its attraction, and the limit on the spring three 1303 is cancelled. The elastic potential energy of the spring three 1303 is released, driving the magnetic block 1304 to rebound, and the magnetic block 1304 drives The reel 1305 and the block 1307 rotate on the inner wall of the square groove 511, and the reel 1305 rotates to drive the wire rope 1306 to reel. When the wire rope 1306 is reeled, it drives the piston 1308 to move on the inner wall of the gas collecting pipe 1310 to extract the air from the inner wall of the gas transmission pipe 1311. When the piston 1308 moves to the notch of the gas collecting pipe 1310, the electromagnet 1302 is energized, and the electromagnet 1302 and the magnetic block 1304 attract each other with opposite charges, so that the magnetic block 1304 304 is fitted with the outer wall of the electromagnet 1302, and when the block 1307 moves out of the inner wall of the square groove 511, the limit on the reel 1305 and the second torsion spring 1315 is cancelled, and the elastic potential energy of the second torsion spring 1315 is released, driving the steel wire rope 1306 to unwind, and the steel wire rope 1306 presses the piston 1308, and the piston 1308 moves on the inner wall of the gas collecting pipe 1310, pushing the gas to press the inner wall of the gas transmission pipe 1311, and the gas collecting pipe 1310 and the gas transmission pipe 1311 are pressed. The inner wall of 311 forms a sealed space, and the piston 1308 pushes the gas to press the sealing block 1312. The sealing block 1312 moves in the notch of the gas pipe 1311, driving the extension plate 1313 and the pressure rod 1314 to press the support rod 10, assisting the support rod 10 to rotate, and preventing the rotating block 16 from pressing the transmission belt 7 when rotating and deflecting, increasing the friction, reducing the deflection effect of the vertical rod 509, and thus improving the detection effect of the monitoring component 5.
