Description

Technical Field

[0001] This invention relates to the field of intelligent inspection technology for scraper conveyors, specifically an intelligent inspection trolley for scraper conveyors and a scraper conveyor. Background Technology

[0002] Scraper conveyors are widely used in the coal mining industry, undertaking the tasks of transporting and transferring coal. The scraper chain and dumbbells of the conveyor are both wear parts and require regular inspection and replacement. Normally, during maintenance shifts, workers check each scraper nut individually for tightness, loss, chain wear, and dumbbell deformation. This is time-consuming and labor-intensive, and different workers may have different judgment standards, easily leading to missed or false alarms, causing subsequent equipment failures and affecting coal mining efficiency. With the continuous development of intelligent mines, the level of intelligence in underground coal mining equipment is increasing. To effectively reduce the labor intensity and safety risks of underground personnel and improve their work efficiency, it is imperative to develop an intelligent detection device to replace manual inspection. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an intelligent inspection trolley for scraper conveyors, including a trolley frame, a drive wheel, a driven wheel, a geared motor, a power supply, a detection system, etc., which can detect the health status of the scraper chain and the deformation of the dumbbells, and upload the detection results. At the same time, it can transport heavier parts back and forth between the head and tail of the conveyor.

[0004] Another objective of this invention is to provide a scraper conveyor equipped with an intelligent inspection trolley that uses the upper surfaces of the side troughs of the conveyor as its travel track. This trolley can replace manual inspection work during maintenance shifts, improving inspection efficiency and accuracy while reducing inspection costs, labor intensity, and safety risks for workers.

[0005] The technical solution adopted in this invention is: an intelligent inspection trolley for a scraper conveyor.

The drive wheel 20 and the driven wheel 22 are composed of a traveling surface and a guide surface. The traveling surface contacts the upper surface of the shovel plate groove 41 and the baffle groove 42, and the guide surface contacts the inner side of the shovel plate groove 41 and the baffle groove 42. The drive wheel 20 and the driven wheel 22 are connected to the wheel frame 111 through wheel axle A19 and wheel axle B23, respectively. The reduction motor 13 is connected to wheel axle A19 and is fixedly installed below the trolley frame 11 through the fixing frame 12.

Detailed Implementation

[0017] The following is a detailed description of specific embodiments of the present invention with reference to the accompanying drawings:

[0018] like Figures 1-6 As shown, this invention discloses an intelligent inspection trolley for a scraper conveyor. The inspection trolley 1 is mounted on the central trough 4. The traveling surfaces of the drive wheel 20 and driven wheel 22 are in contact with the upper surfaces of the shovel trough side 41 and the baffle trough side 42, while the guide surfaces of the drive wheel 20 and driven wheel 22 are in contact with the inner sides of the shovel trough side 41 and the baffle trough side 42. The inspection trolley 1 uses the upper surfaces of the shovel trough side 41 and the baffle trough side 42 as its traveling track, allowing it to travel on the entire working face scraper conveyor and pass under the coal mining machine 2. The outer side of the wheel frame 111 below the trolley frame 11 is triangular, which can clean the coal on the upper surfaces of the shovel trough side 41 and the baffle trough side 42 in front of the inspection trolley 1, ensuring smooth movement of the inspection trolley 1 and reducing the impact on detection accuracy. The power supply 14 supplies power to the reduction motor 13 and the detection system.

[0019] The inspection vehicle 1 carries a detection system including a control box 17, a wireless communication module 16, an intelligent camera 15, a magnetic sensor 18, an inductive sensor 21, and a shaft encoder 24. The intelligent camera 15, inductive sensor 21, magnetic sensor 18, and shaft encoder 24 are connected to the control box 17 via signal lines. The control box 17 interacts with the central control center via the wireless communication module 16. The wireless communication module 16 uses WiFi communication, with a wireless bridge AP deployed every 30m on the work surface. Each bridge is interconnected, ensuring wireless signal coverage across the entire work surface. The intelligent camera 15 uses AI video recognition to detect scraper deformation and missing scraper nuts. If scraper damage or deformation or missing scraper nuts are detected, the signal is uploaded to the central control center via the wireless communication module 16. Simultaneously, the intelligent camera 15 can determine the distance to obstacles ahead. When the distance to an obstacle is less than the safe distance, [further information is needed]. The control geared motor 13 is stopped; the magnetic sensor 18 is installed in the mounting bracket 112 below the trolley frame 11, located above the two chains of the scraper chain 3, and detects chain damage and breakage in a non-contact manner, and uploads the judgment result to the central control center through the wireless communication module 16; the inductive sensor 21 is installed on both sides of the middle of the trolley frame 11, located above the scraper groove side 41 and the baffle groove side 42, respectively, and can detect the distance L between the middle grooves 4 of two adjacent sections, thereby judging the extension and deformation of the connecting dumbbell between the middle grooves 4. When the extension and deformation exceeds the use limit, the signal is uploaded to the central control center through the wireless communication module 16; the shaft encoder 24 is installed at the tail end of the geared motor 13, and can transmit the specific position signal of the inspection trolley 1 on the scraper conveyor to the control box 17. The control box 17 uploads the position information when a fault is detected to the central control center through the wireless communication module 16.

[0020] The inspection trolley 1 uses the upper surface of the side troughs on both sides of the conveyor as its running track, and travels back and forth from the head to the tail of the entire conveyor to carry out inspections. When needed, the inspection trolley 1 can replace manual labor to transport heavier parts.

[0021] To achieve the above objectives, the present invention also provides a scraper conveyor equipped with the aforementioned intelligent inspection trolley for scraper conveyors. Since the scraper conveyor includes the aforementioned intelligent inspection trolley, it also possesses the above-mentioned technical effects, which will not be elaborated further.

Those skilled in the art, based on reading this specification, can modify the technical solutions described in the embodiments or make equivalent substitutions for some of the technical features, and such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
