Then, in cooperation with the speed sensor and the controller at the end of the conveying pipe, after the conveyor belt exceeds the set speed, the controller can automatically control the start of the cylinder to control the lifting of the damping bed, playing a role of rapid damping. By arranging a U-shaped frame above the damping bed, and installing temperature sensors and smoke sensors on the top of the cross plate and on the U-shaped frame, the temperature of the upper and lower surfaces of the conveyor belt and the surrounding environment conditions can be detected during the use of the conveyor belt.

Detailed Embodiment

[0023] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present utility model are not limited thereto.

[0024] Such as Figures 1 - 3As shown in the figure, this embodiment provides an intelligent damping device for a belt conveyor, including a frame 1 and conveying rollers 2 evenly installed along the length direction of the frame 1 and supporting the conveyor belt. A speed sensor 3 is installed at the end of the conveying roller 2. Inside the frame 1, a cross plate 4 is provided between two groups of conveying rollers 2. At both ends of the top of the cross plate 4, cylinders 5 are installed. The output end of the cylinder 5 is installed with a damping bed 6. There is a gap between the top of the damping bed 6 and the bottom of the conveyor belt. A U-shaped frame 7 is provided between the two sides of the frame 1 and above the damping bed 6. Temperature sensors 9 are installed at one end of the top of the cross plate 4 and at the corresponding positions on the U-shaped frame 7. Smoke sensors 10 are installed at the other end of the top of the cross plate 4 and at the corresponding positions on the U-shaped frame 7. A controller 8 is installed on one side of the U-shaped frame 7. A spraying mechanism is provided at the inner top of the U-shaped frame 7. An alarm 11 is installed at one end of the top of the U-shaped frame 7. The output ends of the speed sensor 3, the temperature sensor 9, and the smoke sensor 10 are electrically connected to the controller 8 through wires. The output end of the controller 8 is electrically connected to the cylinder 5, the spraying mechanism, and the alarm 11 through wires. A cleaning mechanism for removing impurities from the surface of the damping bed 6 is provided on the U-shaped frame 7.

[0025] Overall working principle: During use, the conveyor belt is attached to the surface of the conveying roller 2, and the damping bed 6 is located between two groups of conveying rollers 2. To increase the damping effect, multiple groups of damping devices can be set on the frame 1. During transportation, the speed sensor 3 detects the rotation speed of the conveying roller 2, and then the conveying speed of the conveyor belt can be obtained, and the measurement result is transmitted to the inside of the controller 8. The rotation speed of the conveyor belt is set in the internal system of the controller 8. When the conveying speed is greater than the set threshold, the controller 8 controls the cylinder 5 to start, and the cylinder 5 raises the height of the damping bed 6. The damping bed 6 is attached to the bottom of the conveyor belt to decelerate the conveyor belt. In addition, the lifting and lowering of the cylinder 5 can also be directly controlled to control the transportation of the conveyor belt. During the use of the device, the temperature sensor 9 and the smoke sensor 10 detect the temperature on the surface of the conveyor belt and the smoke situation in the environment. After the temperature reaches the set threshold, the controller 8 controls the spraying mechanism to perform a cooling operation. When the smoke sensor reaches the set threshold, the alarm 11 performs an alarm operation, and at the same time, the spraying system is also started to ensure the safety of the transportation environment. In addition, before controlling the rise of the damping bed 6, the cleaning mechanism is used to clean the impurities on the surface of the damping bed 6 to ensure the attachment effect between the damping bed 6 and the conveyor belt.

[0026] In this embodiment, the shape of the damping bed 6 is the same as the shape of the groove on the conveyor belt, and anti-slip lines are evenly opened on the damping bed 6.

[0027] Local working principle: It increases the contact area and friction force between the damping bed 6 and the conveyor belt, ensuring the damping effect.

[0028] In this embodiment, the distance between the top of the damping bed 6 and the bottom of the conveyor belt during movement is 2 - 10 mm.

[0029] Local working principle: The gap between the top of the damping bed 6 and the conveyor belt avoids wear when the conveyor belt moves, ensuring the service life of the conveyor belt.

[0030] In this embodiment, the set threshold temperature for detecting the surface of the conveyor belt in the internal system of the controller 8 is 42 °C, and the set threshold for the smoke detector in the internal system of the controller 8 is 4% obs / m.

[0031] Local working principle: When the temperature is higher than 42 °C, the spraying mechanism performs a cooling operation. When the smoke detector is greater than 4% obs / m, the spraying mechanism and the alarm 11 operate simultaneously to extinguish the fire and give an alarm at the same time.

[0032] In this embodiment, the spraying mechanism includes a water pump 12, a spray pipe 13 and a spray head 14. The water pump 12 is installed on the side of the U-shaped frame 7. A spray pipe 13 is horizontally installed between the two sides of the U-shaped frame 7. Spray heads 14 are evenly arranged along the length direction at the bottom of the spray pipe 13. The output end of the water pump 12 is connected to the spray pipe 13.

[0033] Local working principle: When performing spraying for cooling and fire extinguishing, the controller 8 controls the water pump 12 to start. The input end of the water pump 12 is pre-connected to the water pipe. The water pump 12 extracts water and discharges it from the spray heads 14 to evenly spray the surface of the conveyor belt. When the surface of the conveyor belt drops below the set temperature, the water pump 12 is turned off.

[0034] In this embodiment, the spray head 14 is a duckbill spray head, and the spray head 14 is inclined towards the moving direction of the conveyor belt.

[0035] Local working principle: The setting of the duckbill spray head increases the spraying area and ensures the spraying and cooling effect.

[0036] In this embodiment, the cleaning mechanism includes an air pump 15, an air pipe 16 and an exhaust port 17. The air pump 15 is installed on the top of the U-shaped frame 7. The air pipe 16 is opened inside the U-shaped frame 7. Exhaust ports 17 are inclinedly opened on the inner side of the U-shaped frame 7 and at the top position of the damping bed 6. The exhaust ports 17 are communicated with the air pipe 16. The output end of the air pump 15 is communicated with the air pipe 16.

[0037] Local working principle: Before the damping bed 6 is lifted, the air pump 15 starts to discharge compressed gas through the exhaust port 17. The high-pressure gas blows on the top of the damping bed 6 to remove impurities.

[0038] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
