Abstract
Description
Technical Field
[0001] This utility model relates to the field of tubular belt conveyor technology, specifically a tube collapse detection structure for a tubular belt conveyor. Background Technology
[0002] Tubular belt conveyors are a new type of conveyor that combines the characteristics of pipeline conveying and belt conveying. They are formed by using polygonal idler rollers arranged at specific intervals to force the belt to wind, resulting in greater lateral rigidity compared to ordinary belt conveyors. However, after prolonged operation, due to belt aging, increased load, and long-term downtime, the lateral rigidity of the belt decreases, making it prone to belt collapse. This can lead to material spillage and environmental pollution, or even serious accidents such as belt misalignment, tearing, or fires. Currently, existing detection devices lack monitoring for belt collapse, and detection relies heavily on periodic observation by inspection personnel. This method is inefficient, cannot achieve real-time monitoring, and carries the risk of missed detections. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides a tube collapse detection structure for a tubular belt conveyor, including a fixed plate with a hexagonal groove. Three first idlers are spaced apart along the edge of the hexagonal groove on the front side of the fixed plate, and three second idlers are spaced apart along the edge of the hexagonal groove on the rear side of the fixed plate. The first and second idlers are staggered. Support plates are connected to the ends of the first and second idlers respectively. The support plates are fixedly connected to the fixed plate by bolts. A sensing block is located on the outer side of the support plate corresponding to the top first idler. A bracket is spaced apart on one side of the sensing block, and a speed sensor is mounted on the bracket. The sensing block and the speed sensor are signal-connected. A belt is installed inside the hexagonal groove, and the first and second idlers abut against the belt. The distance between the top first idler and its corresponding side of the hexagonal groove is smaller than the distance between the other idlers and their corresponding sides of the hexagonal groove.
[0004] The support plate is L-shaped.
[0005] The support plate is fixedly connected to the first or second idler roller by bolts.
[0006] The bracket is fixedly connected by bolts and a fixing plate.
[0007] The distance between the first idler roller located at the top and one side of its corresponding hexagonal groove is 5mm-10mm less than the distance between the other idlers rollers and one side of their corresponding hexagonal grooves.
[0008] Compared with the prior art, this utility model uses fixed idlers and speed sensors to monitor the collapse of the tubular belt conveyor in real time, thereby achieving early warning to avoid accidents, reducing labor costs, and has a simple and highly scalable structure with strong stability and reliability.

[0010] The present invention will be further described below with reference to the accompanying drawings.
[0011] like Figures 1 to 2 A tube collapse detection structure for a tubular belt conveyor includes a fixed plate 1 with hexagonal grooves. Three first idlers 3 are spaced apart along the edge of the hexagonal grooves on the front side of the fixed plate 1, and three second idlers 4 are spaced apart along the edge of the hexagonal grooves on the rear side of the fixed plate 1. The first idlers 3 and second idlers 4 are staggered. Support plates 5 are connected to the two ends of the first idlers 3 and second idlers 4, respectively. The support plates 5 are fixedly connected to the fixed plate 1 by bolts. A sensing block 6 is located on the outer side of the support plate 5 corresponding to the top first idler 3. A bracket 7 is provided on one side of the sensing block 6, and a speed sensor 8 is provided on the bracket 7. The sensing block 6 and the speed sensor 8 are connected to each other to ensure that the sensing block 6 can be effectively detected by the sensor 8 when it rotates with the idler roller. A belt 2 is provided in the hexagonal groove. The first idler roller 3 and the second idler roller 4 abut against the belt 2. The distance between the first idler roller 3 at the top and its corresponding side of the hexagonal groove is smaller than the distance between the other idler rollers and their corresponding side of the hexagonal groove. This avoids poor contact between the belt and the top idler roller due to installation errors, which would lead to malfunction of the detection device.
[0012] The support plate 5 is L-shaped.
[0013] The support plate 5 is fixedly connected to the first idler roller 3 or the second idler roller 4 by bolts. The bracket 7 is fixedly connected to the fixing plate 1 by bolts to ensure the stability of the equipment.
[0014] The distance between the first idler roller 3 at the top and one side of its corresponding hexagonal groove is 5mm-10mm less than the distance between the other idlers and one side of their corresponding hexagonal grooves.
[0015] When the pipeline conveyor is running, the speed sensor 8 continuously outputs a signal at a constant speed to determine that the belt is running normally. When a pipe collapse occurs, the belt 2 will lose contact with the speed sensor 8 and the sensing block 9 will be removed. The speed sensor 8 will then stop outputting a signal, indicating a pipe collapse fault, and will issue an audible and visual alarm or a shutdown command to remind the staff to handle the situation promptly.
