Description

Technical Field

[0001] This invention relates to the field of conveyor belt technology, and in particular to a conveyor belt correction device. Background Technology

[0002] Pipe belt conveyors are a new type of conveyor that combines pipeline conveying and belt conveying. They have advantages such as large conveying angle and three-dimensional curved conveying. They are usually used to convey various lumpy and powdery materials such as ore, cement and coal. However, during the operation of sintering pipe belt conveyors, belt misalignment can cause belt conveyor pipe breakage and twisting failures.

[0003] A search revealed a Chinese patent with publication number CN217497452U that discloses an anti-torsion device for a circular tube belt conveyor. The anti-torsion device includes a roller frame, a guiding roller, a universal ball, a sliding rod, and a lower support. The guiding roller is mounted on the roller frame, and the roller frame is equipped with two sliding rods that pass through the U-shaped slide rails of the lower support.

[0004] In the above-mentioned technology, although the anti-torsion device is designed to correct the belt conveyor, the anti-torsion device is a purely mechanical structure and cannot detect the belt conveyor's deviation. Due to the special nature of the belt conveyor, when the belt deviates, the belt folds or twists. The anti-torsion device cannot detect the fault in time, resulting in excessively long folded or twisted tubes, the inability of the tubular belt to open normally, or even the entire tubular belt flipping over. This expands the scope of the fault and increases the fault handling time.

[0005] Therefore, the present invention provides a belt conveyor correction device. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the limitations of the prior art.

[0007] To solve the above-mentioned technical problems, the present invention provides a belt conveyor correction device, comprising:

[0008] The base has a tube bending detection mechanism at one top end and a tube twisting detection mechanism at the other top end.

[0009] The tube bending detection mechanism includes a first support frame, a roller, and a tube bending detection switch. The bottom of the first support frame is fixedly connected to the base, and the top two ends of the first support frame are respectively fixedly connected to connecting columns. One end of the side wall of the connecting column is provided with a sliding groove, and a slider is slidably connected in the sliding groove. The two sliders are rotatably connected to the roller. The tube bending detection switch is installed at the end of the connecting column of the roller.

[0010] The torsion tube detection mechanism includes a second support frame, a swing rod, and a torsion tube detection switch. The bottom of the second support frame is fixedly connected to the base. Two U-shaped frames are fixedly connected to the inner side of the top of the second support frame. The bottom of the two U-shaped frames are rotatably connected to the swing rod. The torsion tube detection switch is installed on the second support frame above the swing rod.

[0011] The base is equipped with a controller located adjacent to the second support frame, and both the folding tube detection switch and the twisting tube detection switch are electrically connected to the controller.

[0012] In one embodiment of the present invention, the tube fold detection switch includes a first infrared transmitter and a first infrared receiver, which are respectively installed at both ends of the connecting post. The transmitting end of the first infrared transmitter is connected to the slide groove, and the receiving end of the first infrared receiver is connected to the slide groove. Both the first infrared transmitter and the first infrared receiver are electrically connected to the controller.

[0013] In one embodiment of the present invention, corresponding through holes are provided at the bottom of the sidewalls at both ends of the slide, and the through holes are movably connected to the first infrared transmitter and the first infrared receiver.

[0014] In one embodiment of the present invention, the torsion tube detection switch includes a second infrared transmitter and a second infrared receiver. The second infrared transmitter is mounted on the top of the swing rod, and the second infrared receiver is mounted on the inner side of the top of the second support frame and located directly above the swing rod. Both the second infrared transmitter and the second infrared receiver are electrically connected to the controller.

[0015] In one embodiment of the present invention, a rotating shaft is fixedly connected to one end of the top of the swing rod, and a torsion spring is respectively sleeved on both ends of the rotating shaft. One end of the torsion spring is fixedly connected to the swing rod, and the other end of the torsion spring is fixedly connected to the U-shaped frame.

[0016] In one embodiment of the present invention, the base is rotatably connected to a first roller below the roller, and the base is rotatably connected to a second roller below the swing arm. The first roller and the second roller are connected by a first synchronous belt drive at the ends away from the controller.

[0017] In one embodiment of the present invention, the base is fixedly connected to the two ends of the first roller with first bearing seats respectively, and the first bearing seats are rotatably connected to the first roller. The base is fixedly connected to the two ends of the second roller with second bearing seats respectively, and the second bearing seats are rotatably connected to the second roller.

[0018] In one embodiment of the present invention, a motor is fixedly connected to the base adjacent to the controller, one end of the first roller is connected to the output shaft of the motor via a second synchronous belt, and the motor is electrically connected to the controller.

[0019] In one embodiment of the present invention, one end of the first roller extends to the outside of the first bearing seat and is fixedly connected to a first synchronous pulley, and one end of the second roller extends to the outside of the second bearing seat and is fixedly connected to a second synchronous pulley. Both the first synchronous pulley and the second synchronous pulley are engaged with the first synchronous belt.

[0020] In one embodiment of the present invention, the motor shaft is fixedly connected to a third synchronous pulley, one end of the first roller extends to the outside of the first bearing seat and is fixedly connected to a fourth synchronous pulley, and both the third and fourth synchronous pulleys are meshed with the second synchronous belt.

[0021] The technical solution of the present invention has the following advantages compared with the prior art:

[0022] The present invention discloses a pipe belt conveyor correction device, which detects pipe bending during pipe belt conveyor operation through the design of a pipe bending detection mechanism. Specifically, a vertically movable idler roller is installed on a first support frame, and pipe bending detection switches are installed on the left and right sides of the idler roller. When the pipe belt conveyor bends, it will push the idler roller upward, thereby driving the slider to move upward. At this time, the slider will leave the detection range of the pipe bending detection switch. Then, the first infrared receiver can receive the signal emitted by the first infrared transmitter and transmit the signal to the controller, thereby triggering the pipe belt conveyor to stop the machine in time and prevent the fault from escalating.

[0023] The present invention discloses a belt conveyor correction device that detects belt twisting during belt conveyor operation through a twist detection mechanism. This device utilizes a swing arm mounted on a second support frame, with a second infrared transmitter switch installed at the top of the swing arm. A second infrared receiver is mounted on the second support frame directly above the second infrared transmitter. When the second infrared receiver receives a signal from the second infrared transmitter, the belt conveyor operates normally. When belt twisting occurs, the belt edge pushes the swing arm to the left or right, causing the second infrared transmitter at the top of the swing arm to move and move out of the receiver's range. When the second infrared receiver can no longer receive the signal from the second infrared transmitter, it triggers a stop signal for the belt conveyor, stopping it promptly and preventing the fault from escalating.

[0024] The conveyor belt correction device of the present invention uses a torsion spring to limit and support the swing arm, preventing it from swinging easily left and right due to wind in the environment, thus ensuring the detection effect of the torsion detection mechanism. In addition, the design of the second synchronous belt allows the motor to drive the first roller to rotate, and the design of the first synchronous belt allows the first roller and the second roller to rotate synchronously. This not only ensures the stability of the conveyor belt during operation, but also allows the motor to drive the first roller and the second roller to rotate simultaneously.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0037] Reference Figures 1 to 9 As shown, the present invention provides a belt conveyor correction device, comprising:

[0038] Base 1, with a tube bending detection mechanism 2 at one top end of base 1 and a tube twisting detection mechanism 3 at the other top end of base 1;

[0039] The tube bending detection mechanism 2 includes a first support frame 21, a roller 22, and a tube bending detection switch 23. The bottom of the first support frame 21 is fixedly connected to the base 1. Connecting columns 24 are fixedly connected to both ends of the top of the first support frame 21. A groove 25 is provided at one end of the side wall of the connecting column 24. A slider 26 is slidably connected in the groove 25. The two sliders 26 are rotatably connected to the roller 22. The tube bending detection switch 23 is installed at the end of the roller 22 on the connecting column 24.

[0040] The torsion tube detection mechanism 3 includes a second support frame 31, a swing rod 32 and a torsion tube detection switch 33. The bottom of the second support frame 31 is fixedly connected to the base 1. Two U-shaped frames 34 are fixedly connected to the inner side of the top of the second support frame 31. The bottom of the two U-shaped frames 34 are rotatably connected to the swing rod 32. The torsion tube detection switch 33 is installed on the second support frame 31 above the swing rod 32.

[0041] The base 1 is located adjacent to the second support frame 31 and the controller 4 is installed thereon. The tube bending detection switch 23 and the tube twisting detection switch 33 are both electrically connected to the controller 4.

[0042] In this embodiment, both the tube fold detection switch 23 and the tube twist detection switch 33 are proximity switches. During normal operation of the conveyor belt machine, the conveyor belt forms a closed tubular structure inside the machine, and the material is transported within this tubular structure. This operating state helps ensure the stability and safety of the material during transport, reducing material spillage and scattering, thereby improving the working environment and reducing material loss. When a tube fold occurs during the operation of the conveyor belt machine, the conveyor belt will push the idler roller 22 upwards, thereby causing the slider 26 to move upwards. At this time, the slider 26 leaves the detection range of the tube fold detection switch 23, and the tube fold detection switch 23 will send a signal to the controller 4, triggering a stop signal for the conveyor belt machine to stop in time and prevent the fault from escalating. When a tube twist occurs during the operation of the conveyor belt machine, the belt edge will push the swing arm 32 to the left or right. At this time, the top of the swing arm 32 will move and leave the detection range of the tube twist detection switch 33, and the tube twist detection switch 33 will then be activated. Switch 33 will transmit a signal to controller 4, triggering the stop signal of the conveyor belt machine, stopping it in time to prevent the fault from escalating. The design of the tube bending detection mechanism 2 and the tube twisting detection mechanism 3 allows the conveyor belt machine to stop in time when tube bending or twisting faults occur, preventing the fault from escalating and reducing fault handling time. When the conveyor belt machine is stopped due to tube bending or twisting faults, the operator can adjust the position and angle of the guide rollers on the conveyor belt to ensure that the conveyor belt maintains the correct position and direction during operation, and adjust the tension of the conveyor belt to correct the belt deviation. Due to the existence of tube bending detection mechanism 2 and tube twisting detection mechanism 3, the conveyor belt machine will stop in time when tube bending or twisting faults occur, so the fault range will be relatively small, thereby reducing the time for the operator to handle the fault. In addition, foreign objects such as stones and wood blocks can jam the conveyor belt or affect the normal operation of the conveyor belt, which can also cause tube bending and twisting faults. Therefore, it is necessary to remove foreign objects such as stones and wood blocks in time when the conveyor belt machine stops.

[0043] The tube bending detection switch 23 includes a first infrared transmitter 231 and a first infrared receiver 232. The first infrared transmitter 231 and the first infrared receiver 232 are respectively installed at both ends of the connecting post 24. The transmitting end of the first infrared transmitter 231 is connected to the slide 25, and the receiving end of the first infrared receiver 232 is connected to the slide 25. Both the first infrared transmitter 231 and the first infrared receiver 232 are electrically connected to the controller 4.

[0044] In this embodiment, when the conveyor belt is running normally, the signal emitted by the first infrared transmitter 231 is blocked by the slider 26, so that the first infrared receiver 232 cannot receive the signal emitted by the first infrared transmitter 231. When the conveyor belt experiences a tube breakage, the conveyor belt will push the idler roller 22 upward, thereby driving the slider 26 to move upward. At this time, the first infrared receiver 232 can receive the signal emitted by the first infrared transmitter 231 and transmit the signal to the controller 4, thereby triggering the conveyor belt to stop the machine in time and prevent the fault from escalating.

[0045] The bottom of the sidewalls at both ends of the slide 25 are respectively provided with corresponding through holes 27, and the through holes 27 are movably connected to the first infrared transmitter 231 and the first infrared receiver 232.

[0046] In this embodiment, the design of the through hole 27 allows the transmitting end of the first infrared transmitter 231 and the receiving end of the first infrared receiver 232 to be smoothly connected to the slide 25. In this way, after the slider 26 moves upward, the signal emitted by the first infrared transmitter 231 can pass smoothly through the slide 25 and be received by the first infrared receiver 232.

[0047] The torsion tube detection switch 33 includes a second infrared transmitter 331 and a second infrared receiver 332. The second infrared transmitter 331 is installed on the top of the swing arm 32, and the second infrared receiver 332 is installed on the inner side of the top of the second support frame 31 and located directly above the swing arm 32. Both the second infrared transmitter 331 and the second infrared receiver 332 are electrically connected to the controller 4.

[0048] In this embodiment, the receiving end of the second infrared receiver 332 is larger than the transmitting end of the second infrared transmitter 331. This ensures that even when the swing arm 32 sways slightly due to wind, the second infrared receiver 332 can still receive the signal emitted by the second infrared transmitter, allowing the conveyor belt to continue operating normally. When the conveyor belt twists during operation, the belt edge will push the swing arm 32 to the left or right. This causes the second infrared transmitter 331 at the top of the swing arm 32 to move, and the signal emitted by the second infrared transmitter will leave the receiving range of the second infrared receiver 332. When the second infrared receiver 332 cannot receive the signal emitted by the second infrared transmitter 331, i.e., when the controller 4 cannot receive the signal emitted by the second infrared transmitter 331, a stop signal for the conveyor belt will be triggered, stopping the machine promptly and preventing the fault from escalating.

[0049] A pivot 35 is fixedly connected to one end of the top of the swing rod 32. Torsion springs 36 are respectively fitted at both ends of the pivot 35. One end of the torsion spring 36 is fixedly connected to the swing rod 32, and the other end of the torsion spring 36 is fixedly connected to the U-shaped frame 34.

[0050] In this embodiment, the design of the torsion spring 36 can limit and support the swing rod 32, so that the swing rod 32 will not swing easily from side to side due to the wind in the environment, thereby ensuring the detection effect of the torsion tube detection mechanism 3. When the tube conveyor has a torsion tube fault, the torque generated is much greater than the elastic force of the torsion spring 36, so that the swing rod 32 can swing smoothly.

[0051] The base 1 is rotatably connected to the first roller 5 below the roller 22, and the base 1 is rotatably connected to the second roller 6 below the swing arm 32. The ends of the first roller 5 and the second roller 6 away from the controller 4 are connected by the first synchronous belt 7.

[0052] In this embodiment, the bottom of the conveyor belt is supported by the design of the first roller 5 and the second roller 6, and the first synchronous belt 7 allows the first roller 5 and the second roller 6 to rotate synchronously, thereby making the conveyor belt more stable during operation.

[0053] The base 1 is fixedly connected to the first bearing seat 8 at both ends of the first roller 5. The first bearing seat 8 is rotatably connected to the first roller 5. The base 1 is fixedly connected to the second bearing seat 9 at both ends of the second roller 6. The second bearing seat 9 is rotatably connected to the second roller 6.

[0054] In this embodiment, the design of the first bearing seat 8 allows the first roller 5 to be smoothly rotatably connected to the base 1, and the design of the second bearing seat 9 allows the second roller 6 to be smoothly rotatably connected to the base 1.

[0055] The base 1 is fixedly connected to the motor 10 at the position adjacent to the controller 4. One end of the first roller 5 is connected to the output shaft of the motor 10 through the second synchronous belt 11. The motor 10 is electrically connected to the controller 4.

[0056] In this embodiment, the design of the motor 10 provides driving force for the rotation of the first roller 5 and the second roller 6. The design of the second synchronous belt 11 enables the motor 10 to smoothly drive the first roller 5 to rotate. When the first roller 5 rotates, it will drive the second roller 6 to rotate through the transmission action of the first synchronous belt 7.

[0057] One end of the first roller 5 extends to the outside of the first bearing seat 8 and is fixedly connected to the first synchronous pulley 12. One end of the second roller 6 extends to the outside of the second bearing seat 9 and is fixedly connected to the second synchronous pulley 13. Both the first synchronous pulley 12 and the second synchronous pulley 13 are meshed with the first synchronous belt 7.

[0058] In this embodiment, the design of the first synchronous pulley 12 and the second synchronous pulley 13 allows the first roller 5 and the second roller 6 to be smoothly connected together by the first synchronous belt 7.

[0059] The motor 10 has a shaft fixedly connected to a third synchronous pulley 14. One end of the first roller 5 extends to the outside of the first bearing seat 8 and is fixedly connected to a fourth synchronous pulley 15. Both the third synchronous pulley 14 and the fourth synchronous pulley 15 are meshed with the second synchronous belt 11.

[0060] In this embodiment, the design of the third synchronous pulley 14 and the fourth synchronous pulley 15 allows the output shaft of the motor 10 and the first roller 5 to be smoothly connected together via the second synchronous belt 11.

[0061] Working Principle: In operation, the bottom of the conveyor belt of the tube conveyor rests on the surfaces of the first roller 5 and the second roller 6. Then, the motor 10 is turned on, and the second synchronous belt 11 rotates under the drive of the motor 10, thereby driving the first roller 5 to rotate. The first roller 5 and the second roller 6 are connected by the first synchronous belt 7, so when the first roller 5 rotates, the second roller 6 rotates synchronously. This ensures that the first roller 5 and the second roller 6 rotate in sync with the conveyor belt, guaranteeing the stability of the conveyor belt. When a tube kink occurs during operation, the conveyor belt will push the idler roller 22 upwards, causing the slider 26 to move upwards. At this time, the slider 26 moves out of the detection range of the tube kink detection switch 23. Then, the first infrared receiver 232 receives the signal emitted by the first infrared transmitter 231 and transmits the signal to the controller 4, triggering the tube conveyor to stop in time. To prevent the malfunction from escalating, when a pipe twist occurs during the operation of the conveyor belt, the belt edge will push the swing arm 32 to the left or right. At this time, the second infrared transmitter 331 at the top of the swing arm 32 will move and leave the receiving range of the second infrared receiver 332. When the second infrared receiver 332 can no longer receive the signal emitted by the second infrared transmitter 331, that is, when the controller 4 cannot receive the signal emitted by the second infrared transmitter 331, the stop signal of the conveyor belt will be triggered, and the machine will stop in time, thereby preventing the malfunction from escalating. In addition, the torsion springs 36 set at both ends of the rotating shaft 35 can limit and support the swing arm 32, preventing the swing arm 32 from easily swinging left and right due to wind in the environment, thus ensuring the detection effect of the pipe twist detection mechanism 3. Through the design of the pipe bending detection mechanism 2 and the pipe twist detection mechanism 3, the conveyor belt can stop in time when pipe bending and twisting faults occur, preventing the fault from escalating and reducing the fault handling time.

[0062] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
