Description

Technical Field

[0001] This utility model relates to the field of flexible conveyor belt monitoring technology, and in particular to a flexible conveyor belt thermal deformation monitoring device. Background Technology

[0002] Flexible conveyor belts are devices that transport materials using conveyor belts made of flexible materials. In industries such as metallurgy, cement, and chemicals, conveyor belts often need to operate in high-temperature environments or with high-temperature materials. Prolonged exposure to heat can cause irreversible thermal shrinkage, warping, or cracking of the conveyor belt (especially its edges), i.e., thermal deformation. If not detected in time, this can lead to minor issues such as belt misalignment and material spillage, or more serious accidents such as belt tearing and fire.

[0003] Currently, there are few existing technologies for monitoring the thermal deformation of flexible conveyor belts, which cannot provide real-time early warnings and have a strong lag, making it difficult for workers to know in a timely manner whether the flexible conveyor belt has deformed. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible conveyor belt thermal deformation monitoring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A flexible conveyor belt thermal deformation monitoring device includes a frame for mounting the flexible conveyor belt. A mounting bracket is fixedly connected to the bottom of the frame. Dovetail grooves are formed on both inner walls of the mounting bracket, and dovetail blocks are slidably connected within the dovetail grooves. A lifting frame is fixedly connected between two dovetail blocks. A fixed shaft is fixedly connected within the lifting frame, and a rotating rod is rotatably connected to the outer side of the fixed shaft. One end of the rotating rod is rotatably connected to a roller that contacts the flexible conveyor belt via a bearing. Torsion springs are sleeved on both sides of the rotating rod on the outer side of the fixed shaft, and both ends of the torsion springs are fixed to the lifting frame and the rotating rod, respectively. An L-shaped rod is fixedly connected to the other end of the rotating rod, and a striking ball is fixedly connected to one side of the L-shaped rod. An adjustment mechanism for adjusting the height of the lifting frame is provided within the mounting bracket, and an alarm mechanism is provided on one side of the frame.

[0006] As a further embodiment of this utility model, the adjusting mechanism includes a lead screw, the bottom of the mounting frame is provided with a threaded hole, the lead screw is threadedly connected in the threaded hole, and the lead screw is rotatably connected to the lifting frame through a bearing.

[0007] As a further embodiment of this utility model, a nylon damping ring that contacts the lead screw is embedded in the threaded hole.

[0008] As a further embodiment of this utility model, the alarm mechanism includes a mounting shaft, which is fixedly connected to one side of the frame, and a bowl for striking the ball is fixedly connected to one side of the mounting shaft.

[0009] As a further embodiment of this utility model, a vibration sensor is fixedly connected to one side of the bowl body, and a buzzer is fixedly connected to one side of the frame body.

[0010] As a further improvement of this utility model, both the mounting frame and the lifting frame are U-shaped structures.

[0011] As a further embodiment of this invention, the roller is located below the flexible conveyor belt near its edge.

[0012] The beneficial effects of this utility model are as follows: 1. In this utility model, the roller contacts the flexible conveyor belt. If the flexible conveyor belt deforms due to heat, the bent and protruding part of the flexible conveyor belt will push the roller to move downward through the rotating rod, thereby causing the alarm mechanism to sound an alarm. This allows the staff to know in time whether the flexible conveyor belt has deformed, thus providing real-time early warning and having good timeliness.

[0013] 2. In this utility model, by using a buzzer and a vibration sensor in combination, when the bowl is struck and vibrates, the vibration sensor will generate a signal, which will cause the buzzer to sound an alarm, providing a secondary alarm. This further improves the accuracy and reliability of the alarm. Even in a high-noise working environment, the device can still trigger the buzzer through the vibration signal, ensuring that the staff can receive clear prompts. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0017] Reference Figures 1-3 A flexible conveyor belt thermal deformation monitoring device includes a frame 1 for mounting a flexible conveyor belt 2. The bottom of the frame 1 is fixed with a mounting frame 4 by bolts. Dovetail grooves 16 are provided on both sides of the inner wall of the mounting frame 4. Dovetail blocks 17 are slidably connected in the dovetail grooves 16. A lifting frame 5 is welded between the two dovetail blocks 17. Both the mounting frame 4 and the lifting frame 5 are U-shaped structures. A fixed shaft 15 is welded inside the lifting frame 5. A rotating rod 12 is rotatably connected to the outside of the fixed shaft 15. One end of the rotating rod 12 is rotatably connected to a roller 11 that contacts the flexible conveyor belt 2 through a bearing. The roller 11 is located below the flexible conveyor belt 2 near the edge. Since the roller 11 is rotating, it will not cause wear to the flexible conveyor belt 2. Torsion springs 10 are sleeved on both sides of the fixed shaft 15 on both sides of the rotating rod 12, and the two ends of the torsion springs 10 are fixed to the lifting frame 5 and the rotating rod 12 respectively. The torsion springs 10 can be stainless steel torsion springs with pit fatigue and a service life of over one million cycles. When using the flexible conveyor belt 2 to transport items, if the flexible conveyor belt deforms due to heat, the deformed protrusion of the flexible conveyor belt 2 will push the roller 11 to rotate downward around the fixed shaft 15 via the rotating rod 12 and cause the torsion spring 10 to generate torque, thereby enabling the flexible conveyor belt 2 to perform detection. An L-shaped rod 8 is welded to the other end of the rotating rod 12. A striking ball 7 is welded to one side of the L-shaped rod 8. An alarm mechanism is provided on one side of the frame 1. The alarm mechanism includes a mounting shaft 14, which is welded to one side of the frame 1. A bowl 6 for striking the striking ball 7 is welded to one side of the mounting shaft 14. The bowl 6 can be made of copper or iron. During the rotation of the rotating rod 12, the L-shaped rod 8 will move upward in an arc. At this time, the L-shaped rod 8 will strike the bowl 6 through the striking ball 7, so that the bowl 6 will make a sound to remind the staff. This allows the staff to understand in time whether the flexible conveyor belt has deformed, thus providing real-time warning and good timeliness.

[0018] A vibration sensor 13 is fixed to one side of the bowl body 6 by bolts, and a buzzer 3 is fixed to one side of the frame body 1 by bolts. It should be noted that: the vibration sensor 13 is model DFR0032, and the vibration sensor 13 is connected to the external PLC control cabinet via a wireless module; the buzzer 3 is model TMB12A05, and the buzzer 3 is connected to the external PLC control cabinet via a connecting cable. Specifically, when the bowl 6 is struck, it will vibrate. The vibration generated by the bowl 6 will be transmitted to the vibration sensor 13. After sensing the vibration, the vibration sensor 13 will generate an electrical signal and transmit the electrical signal to the external PLC control cabinet. After receiving the signal, the PLC control cabinet will activate the buzzer 3 to sound an alarm, which will further improve the accuracy and reliability of the alarm. Even in a high-noise working environment, the device can still trigger the buzzer 3 through the vibration signal to ensure that the staff can receive clear prompt information. The mounting frame 4 is equipped with an adjustment mechanism for adjusting the height of the lifting frame 5. The adjustment mechanism includes a lead screw 9. The bottom of the mounting frame 4 is provided with a threaded hole. The lead screw 9 is threaded into the threaded hole and is rotatably connected to the lifting frame 5 through a bearing. A nylon damping ring that contacts the lead screw 9 is embedded in the threaded hole. Specifically, by rotating the lead screw 9, the lifting frame 5 will move up or down along the dovetail groove 16 via the dovetail block 17, thereby driving the roller 11 to move and change the height of the roller 11. This allows the roller 11 to be adapted to flexible conveyor belts 2 of different thicknesses. At the same time, it can change the pressure of the roller 11 on the flexible conveyor belt 2, and the elastic compression generated by the nylon insert can suppress the loosening displacement caused by the thread rebound.

[0019] Working principle: When the flexible conveyor belt 2 is used to transport items, if the flexible conveyor belt deforms due to heat, the deformed protrusion of the flexible conveyor belt 2 will push the roller 11 to rotate downward around the fixed shaft 15 via the rotating rod 12, and cause the torsion spring 10 to generate torque. At this time, the rotating rod 12 will drive the L-shaped rod 8 to move upward in an arc. The L-shaped rod 8 will then strike the bowl 6 through the striking ball 7, causing the bowl 6 to make a sound to remind the staff. This allows the staff to understand in time whether the flexible conveyor belt has deformed, thus providing real-time warnings with good timeliness. When the protrusion of the flexible conveyor belt 2 is separated from the roller 11, the roller 11 will automatically reset under the force of the torsion spring 10, thereby allowing for subsequent inspection of the flexible conveyor belt 2. When the bowl 6 is struck, it vibrates. This vibration is transmitted to the vibration sensor 13. The vibration sensor 13 generates an electrical signal and transmits it to the external PLC control cabinet. Upon receiving the signal, the PLC control cabinet activates the buzzer 3 to sound an alarm, providing a secondary alarm and further improving the accuracy and reliability of the alarm. Even in a high-noise working environment, the device can still trigger the buzzer 3 through the vibration signal, ensuring that staff can receive clear prompts.

[0020] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
