Description

Technical Field

[0001] This utility model belongs to the field of belt surface detection technology for conveyor belts, and in particular relates to a belt surface tear detection device for conveyor belts. Background Technology

[0002] During the transportation of raw coal, belt conveyors are used for transfer. After prolonged use, the belt surface of the belt conveyor may develop cracks due to contact with raw coal. If the belt continues to transport materials with cracks, it will damage the belt surface, and the material on top of the belt may spill into the conveyor's shaft and become stuck, causing equipment damage. Since it is impossible to determine whether the belt surface is damaged while the belt conveyor is running, belt surface inspection must be carried out when the belt conveyor is not in use. If cracks appear on the belt conveyor during operation, it will increase the risk of belt tearing, resulting in material spillage and equipment damage.

[0003] To address this issue, we provide a belt tear detection device for conveyor belts to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 3 This utility model relates to a belt tear detection device for a conveyor belt, comprising a clamping component 1 and a detection component 2. The clamping component 1 includes two support seats 101, two shaft discs 102, and two clamping rollers 103. The detection component 2 includes four socket seats 201, a laser detection emitting end 202, and a laser receiving end 203. By rotatably mounting the shaft discs 102 on one side of the two support seats 101 in the clamping component 1, and vertically rotating the clamping rollers 103 between the two shaft discs 102, the two clamping rollers 103 clamp the belt edge of the conveyor belt. The belt is clamped and sockets 201 are installed at both ends of the clamping roller 103. The detection component 2 at one end of the socket 201 performs real-time detection on the belt surface. By installing the laser detection emitter 202 in the detection component 2 between the two upper sockets and the laser receiver 203 between the two lower sockets 201, and passing the belt surface of the conveyor through the laser detection emitter 202 and the laser receiver 203, the detection component 2 performs through detection on the belt surface of the conveyor, ensuring the detection of cracks on both sides of the belt surface.

[0027] Specifically, two support seats 101 are arranged facing each other, and a shaft disk 102 is horizontally rotatably mounted on one side of the support seat 101. Two clamping rollers 103 are arranged vertically and their ends are rotatably mounted on the disks of the two shaft disks 102. A socket 201 is fixedly sleeved at each end of the two clamping rollers 103. The two ends of the laser detection emitting end 202 are respectively installed between the two upper sockets 201, and the two ends of the laser receiving end 203 are respectively installed between the two lower sockets 201.

[0028] Furthermore, the shaft disk 102 has two sliding sleeve grooves 102a arranged in a circumferential array on its surface. The length direction of the two sliding sleeve grooves 102a is perpendicular to the horizontal plane. A clamping roller sleeve 102b is slidably sleeved in the sliding sleeve groove 102a. One end of the clamping roller 103 is rotatably mounted on the side of the clamping roller sleeve 102b. A compression spring is fixedly connected to the end face of the clamping roller sleeve 102b away from the axis of the shaft disk 102. The compression spring on the end face of the clamping roller sleeve 102b is fixedly connected to the top surface of the sliding sleeve groove 102a. The compression spring on the end face of the clamping roller sleeve 102b squeezes the clamping roller sleeve 102b, causing the two clamping rollers 103 to clamp the belt surface of the conveyor belt.

[0029] Furthermore, clamping plates 102b-1 are fixed on both sides of the clamping roller sleeve 102b, and the clamping plates 102b-1 extend to the end away from the axis of the shaft disk 102. The clamping plates 102b-1 on both sides clamp the surface of the shaft disk 102, so that the clamping roller sleeve 102b slides stably in the sleeve groove 102a without disengaging.

[0030] The operation process in this embodiment is as follows:

[0031] Two clamping rollers 103 are clamped on the upper and lower sides of the belt surface of the conveyor belt, and another shaft disc 102 is installed on one end of the clamping rollers 103. When the conveyor belt is running, the two clamping rollers 103 clamp the belt surface and keep the belt surface taut, so that the belt surface is conveyed smoothly, thereby enabling the detection component 2 to accurately detect the belt surface.

[0032] Example 2

[0033] Please see Figures 1 to 5 Based on Embodiment 1, the two ends of the socket 201 are respectively equipped with a detection end sliding sleeve frame 201a and a cleaning end sliding sleeve frame 201c. By sliding the detection end sliding sleeve 201a-1 inside the detection end sliding sleeve frame 201a, and connecting the two ends of the laser detection emitting end 202 and the laser receiving end 203 in the detection component 2 to the detection end sliding sleeves 201a-1 at both ends, the detection component 2 can move according to the undulation of the conveyor belt surface, so that the detection distance remains consistent, thereby making the detection result accurate.

[0034] Specifically, a detection end sliding sleeve frame 201a is fixedly provided at one end of the socket 201. A detection end sliding sleeve 201a-1 is vertically slidably sleeved inside the detection end sliding sleeve frame 201a. A compression spring is fixedly connected to the end face of the detection end sliding sleeve 201a-1 away from the axis of the shaft disk 102. The end of the compression spring on the end face of the detection end sliding sleeve 201a-1 away from the detection end sliding sleeve 201a-1 is fixedly connected to the frame surface of the detection end sliding sleeve frame 201a. Limiting rollers 201b are rotatably installed between the two ends of the detection end sliding sleeves 201a-1 on both sides of the socket 201.

[0035] Furthermore, a mounting base 201a-2 is fixedly installed on the detection end sliding sleeve 201a-1, and the two ends of the laser detection emitting end 202 are respectively installed between the two mounting bases 201a-2 at the upper end, and the two ends of the laser receiving end 203 are respectively installed between the two mounting bases 201a-2 at the lower end.

[0036] Furthermore, a cleaning end sliding frame 201c is fixedly provided at the end of the socket 201 away from the detection end sliding frame 201a. A cleaning roller sliding sleeve 201c-1 is vertically slidably sleeved inside the cleaning end sliding frame 201c. A felt cleaning roller 201d is rotatably installed between the cleaning roller sliding sleeves 201c-1 on both sides of the cleaning end sliding frame 201c. A compression spring is fixedly connected to the end face of the cleaning roller sliding sleeve 201c-1 away from the axis of the shaft disk 102. The end of the compression spring at one end of the cleaning roller sliding sleeve 201c-1 away from the cleaning roller sliding sleeve 201c-1 is fixedly connected to the frame surface of the cleaning end sliding frame 201c. The felt cleaning roller 201d clamps the belt surface of the conveyor belt. When the conveyor belt is running, impurities such as coal slag on the belt surface are cleaned when passing through the felt cleaning roller 201d, thereby preventing the coal slag on the belt surface from affecting the detection results.

[0037] Furthermore, two through holes are vertically arrayed on the plate surface of the support base 101, and two tie rods 101a pass through the two through holes on the two support bases 101, so that the two support bases 101 are stably installed on both sides of the belt conveyor.

[0038] The operation process in this embodiment is as follows:

[0039] When the belt conveyor is running, the coal slag impurities on the surface are cleaned when the belt surface passes through the felt cleaning roller 201d. If the belt surface undulates after passing through the clamping roller 103, the limiting roller 201b clamps the belt surface to ensure that the belt surface running smoothly is detected in real time by the laser emission detection end 202 and the laser receiving end 203.
