Technical Field
[0001] This utility model relates to the field of belt conveyor equipment, and in particular to a self-moving tail section for a retractable belt conveyor. Background Technology
[0002] In the mining and transportation sector, transshipment is a crucial link in the transportation system. Due to terrain, equipment layout, and other factors, the tail section of the conveyor often needs to be moved for transshipment. When this movement cannot be coordinated, it often leads to problems such as transport congestion or wasted manpower. Because belt conveyors are relatively long, the tail section obstructs the passage of vehicles and personnel. Currently, the most common method is to manually adjust the position, which is time-consuming and inconvenient. Utility Model Content

[0004] A self-moving tail section for a retractable belt conveyor includes a drive mechanism, a guide rail, a movable frame, a sliding frame, a telescopic frame, and a sliding column. The telescopic frame is a multi-section telescopic structure, positioned above the guide rail in a direction parallel to the guide rail. The sliding frame is slidably mounted on the telescopic frame, with its sliding direction parallel to the extension direction of the guide rail. The sliding column is positioned below the sliding frame and the multi-section telescopic frame, with a pulley at its bottom end. The pulley is slidably mounted on the guide rail. The movable frame is positioned at the end of the telescopic frame away from the conveyor, and is fixedly connected to the sliding frame.

[0005] Based on the above scheme, the driving mechanism includes a hydraulic station and a hydraulic cylinder. The cylinder barrel of the hydraulic cylinder is fixedly connected to the hydraulic cylinder fixed seat, and the hydraulic cylinder piston is connected to the hydraulic cylinder movable seat. The hydraulic cylinder movable seat is fixedly connected to the moving frame. When the hydraulic cylinder piston is in the extended position, the moving frame, sliding frame, and telescopic frame are in the unfolded state. When the hydraulic cylinder piston is in the retracted position, the moving frame, sliding frame, and telescopic frame are in the retracted state.
[0006] Preferably, the device also includes a laser scanner for detecting the amount of material on the conveyor belt by laser scanning.
[0007] Based on the above scheme, the image sensor is fixedly connected to the sliding frame via a sensor bracket, and the laser scanner is fixedly connected to the sliding frame via a scanner bracket.
[0008] Preferably, an X-shaped movable bracket is hinged between adjacent sliding columns, and a movable block is hinged at the end of the movable bracket.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0020] like Figures 1 to 3 As shown, a self-moving tail section for a retractable belt conveyor includes a drive mechanism, a guide rail 2, a moving frame 31, a sliding frame 41, a telescopic frame 5, and sliding columns 61. The telescopic frame 5 is a multi-section telescopic structure, with adjacent sections nested together and movable relative to each other. The telescopic frame 41 is positioned above the guide rail 2 in a direction parallel to the guide rail 2. The sliding frame 41 is slidably mounted on the telescopic frame 5, with its sliding direction parallel to the extension direction of the guide rail 2. A limiting mechanism is provided between the ends of the sliding frame 41 and the telescopic frame 5 to prevent the sliding frame 41 from detaching from the telescopic frame 5. Multiple sliding columns 61 are positioned below the sliding frame 41 and the multi-section telescopic frame 5. A pulley 64 is provided at the bottom of each sliding column 61, and the pulley 64 is slidably mounted on the guide rail 2. Specifically, the pulley 64 has a groove in the middle, and the guide rail 2 has an upward protrusion in the middle to form a slide. The slide is engaged in the groove to prevent the pulley 64 from falling off the slide.
[0021] An X-shaped movable bracket 62 is hinged between adjacent sliding columns 61. A movable block 63 is hinged to the end of the movable bracket 62. A sliding groove is provided on the sliding column 61 along the vertical direction. The movable block 63 is slidably disposed in the sliding groove.
[0022] The movable frame 31 is located at the end of the telescopic frame 5 on the side away from the conveyor. The movable frame 31 is fixedly connected to the sliding frame 41. The bottom of the movable frame 31 is provided with a pulley 64. The drive mechanism drives the movable frame 31 and the sliding frame 41 to slide along the direction of the guide rail 2. The movable frame 31 is provided with a redirecting roller 32 and an auxiliary roller 33. The sliding frame 41 is provided with a roller support 42. The roller support 42 is provided with a carrying roller 43 and a return roller 44 for supporting the conveyor belt.
[0023] It also includes an image sensor 71, which is used to capture images of the pedestrian walkway behind the mobile frame 31. The image sensor 71 can identify vehicles and pedestrians.
[0024] It also includes a tensioning device (not shown in the figure), on which the conveyor belt is fitted.
[0025] Preferably, the driving mechanism includes a hydraulic station 11 and a hydraulic cylinder 13. The cylinder barrel of the hydraulic cylinder 13 is fixedly connected to the hydraulic cylinder fixed seat 12, and the piston of the hydraulic cylinder 13 is connected to the hydraulic cylinder movable seat 14. The hydraulic cylinder movable seat 14 is fixedly connected to the moving frame 31. When the piston of the hydraulic cylinder 13 is in the extended position, the moving frame 31, the sliding frame 41, and the telescopic frame 5 are in the unfolded state. When the piston of the hydraulic cylinder 13 is in the retracted position, the moving frame 31, the sliding frame 41, and the telescopic frame 5 are in the retracted state.
[0026] It also includes a laser scanner 81, which is used to detect the amount of material on the conveyor belt by laser scanning. The image sensor 71 is fixedly connected to the sliding frame 41 via a sensor bracket 72, and the laser scanner 81 is fixedly connected to the sliding frame 41 via a scanner bracket 82.
[0027] like Figure 3 As shown, when the image sensor detects a vehicle or pedestrian needing to pass through the pedestrian walkway, it transmits a signal to the central control unit of the belt conveyor. The central control unit then stops the conveyor belt. Subsequently, the drive mechanism moves the piston of hydraulic cylinder 13 to the retracted position, and the tensioning device tensions the conveyor belt to prevent it from sagging. At this point, the tail section of the conveyor belt retracts, allowing vehicles and pedestrians to pass through the pedestrian walkway. When the image sensor detects no vehicle or pedestrian in the pedestrian walkway, it transmits a signal to the central control unit of the belt conveyor. The drive mechanism moves the piston of hydraulic cylinder 13 to the extended position, and the tensioning device releases the belt. At this point, the tail section of the conveyor belt unfolds, and the central control unit controls the conveyor belt to continue rotating for material transport.
[0028] When the laser scanner detects a large amount of material on the conveyor belt, the central control unit speeds up the conveyor belt to increase material transport speed and prevent material accumulation; when the laser scanner detects a small amount of material on the conveyor belt, the central control unit reduces the conveyor belt speed to ensure material transport needs while reducing energy consumption costs.
[0029] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
