[0002] During mining operations, materials are transported via belt conveyors. In existing technologies, such as the document with application number CN201711487147.8, the belt is tightened by bolts. Although this can achieve tension adjustment, it has the following drawbacks: it requires manual adjustment, which is extremely inefficient. Furthermore, the distance the belt pulleys move at both ends is not easy to control when adjusting with bolts, making it very easy for the belt to run off-track. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a tensioning mechanism for mining belt conveyors, thus solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The tensioning mechanism of a mining belt conveyor includes a frame, slide rails, belt body, winch, and trolley, and also includes; The tension roller and guide roller are connected by a tension roller belt that wraps around the guide roller. The winch pulls the tension roller and the sliding carriage to slide towards one end of the frame. An adjusting plate and guide rollers are mounted on the adjusting plate, which can deflect horizontally. The positioning hole and the insertion rod are used to hold one end of the sliding carriage in place to prevent it from sliding under the tension of the belt body.

[0005] Furthermore, the tension roller is installed at one end of the trolley, the winch is installed at the end away from the trolley, and a fixing point is installed on the frame at the end away from the trolley. A wire rope is installed between the winch and the fixing point, and the wire rope passes around the tension roller.

[0006] Furthermore, a fixed shaft is installed on the upper surface of the sliding carriage, a bearing is installed on the fixed shaft, an adjusting plate is installed on the bearing, multiple adjusting plates are provided, multiple guide rollers are provided and correspond one-to-one with the adjusting plates, a connecting rod is installed between adjacent adjusting plates, the connecting rod is hinged to the adjusting plate, and a hydraulic rod is installed between the adjusting plate and the sliding carriage.

[0007] Furthermore, a square beam is installed at the middle of the lower end of the frame, and a positioning hole is opened on the square beam. One end of the insertion rod is Z-shaped and is inserted into the positioning hole. The Z-shape can prevent the insertion rod from moving horizontally. A threaded hole is opened on the insertion rod, and a threaded shaft is installed in the threaded hole. A crossbeam is installed at one end of the threaded shaft. The crossbeam and the threaded shaft are rotatably set. The crossbeam has an L-shaped cross section and can be placed on a sliding trolley.

[0008] Furthermore, the guide rollers are divided into fixed rollers and movable rollers. The movable rollers are mounted on the trolley, and the fixed rollers are mounted on the frame.

[0009] The beneficial effects of this utility model are: the belt body can be quickly tensioned by the operation of the winch, and the belt body can be quickly deviated by the function of the adjusting plate; The insertion rod prevents the winch from continuously applying pressure to the belt body, thus increasing the winch's service life.

[0011] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0012] This application provides a tensioning mechanism for mining belt conveyors; please refer to [reference needed]. Figures 1-4 It includes a frame 1, a slide rail 2, a belt conveyor body 3, a winch 4, and a trolley 5, and also includes; Tensioning roller 6 and guide roller 7, tensioning roller 6 belt body 3 passes around guide roller 7, winch 4 pulls tensioning roller 6 and sliding carriage 5 to slide towards one end of frame 1; Adjusting plate 8 and guide roller 7 are mounted on adjusting plate 8, and adjusting plate 8 can deflect in the horizontal direction; Positioning hole 9 and insertion rod 10, the insertion rod 10 abuts against one end of the sliding carriage 5 to prevent the sliding carriage 5 from sliding under the tension of the belt body 3.

[0013] In practical applications, the winch 4 and the trolley 5 are existing technologies. The trolley 5 is slidably connected on the slide rail 2, and the slide rail 2 is fixedly connected to the frame 1. When the winch 4 is working, it drives the tension roller 6 and the trolley 5 to move. The tension roller 6 pulls the belt body 3 toward one end of the winch 4, and finally achieves the tensioning effect. By adjusting the setting of the plate 8, the guide roller 7 can rotate within a horizontal range, adjusting the operating state between the belt body 3 and the guide roller 7, thereby preventing the belt body 3 from running off-center. When the winch 4 pulls the belt body 3 to the specified tension, the positioning hole 9 and the insertion rod 10 can counteract the pulling force of the belt body 3 on the sliding carriage 5, thereby releasing the winch 4 and stopping the winch 4 from exerting force.

[0014] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Tensioning roller 6 is installed at one end of sliding carriage 5, winch 4 is installed at the end away from sliding carriage 5, fixed point 11 is installed on frame 1, fixed point 11 is located at the end away from sliding carriage 5, and wire rope 12 is installed between winch 4 and fixed point 11, wire rope 12 passes around tensioning roller 6.

[0015] In practical applications, when the winch 4 is working, it pulls the wire rope 12, which causes the tensioning roller 6 to pull the sliding carriage 5 to move. The sliding carriage 5 then pulls the belt body 3 to increase the circulation path, ultimately achieving tensioning.

[0016] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A fixed shaft 51 is installed on the upper surface of the sliding carriage 5, and a bearing 52 is installed on the fixed shaft 51. An adjusting plate 8 is installed on the bearing 52. There are multiple adjusting plates 8. There are multiple guide rollers 7, which correspond one-to-one with the adjusting plates 8. A connecting rod 53 is installed between adjacent adjusting plates 8. The connecting rod 53 is hinged to the adjusting plate 8. A hydraulic rod 54 is installed between the adjusting plate 8 and the sliding carriage 5.

[0017] In practical applications, the fixed shaft 51 and bearing 52 play a stabilizing role on the adjusting plate 8, allowing the adjusting plate 8 to rotate stably in the plane. When the belt body 3 deviates to one side, the hydraulic rod 54 is extended or retracted to make the guide roller 7 deviate in the opposite direction, ultimately achieving the effect of correcting the deviation.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A square beam 31 is installed at the middle of the lower end of the frame 1. A positioning hole 9 is opened on the square beam 31. One end of the insertion rod 10 is Z-shaped and is inserted into the positioning hole 9. The Z-shaped setting can prevent the insertion rod 10 from moving horizontally. A threaded hole 32 is opened on the insertion rod 10. A threaded shaft 33 is provided in the threaded hole 32. A crossbeam 34 is installed at one end of the threaded shaft 33. The crossbeam 34 and the threaded shaft 33 are rotatably set. The crossbeam 34 has an L-shaped cross section and can be placed on the sliding car 5.

[0019] In practical applications, after the tension position of the belt body 3 is adjusted, the insertion rod 10 is manually inserted into the positioning hole 9. By setting the lower end of the insertion rod 10 in a Z-shape, the insertion rod 10 can be prevented from moving horizontally to one side. This setting can resist the pulling force of the belt body 3 on the sliding carriage 5, keeping the sliding carriage 5 in a stationary state. At this time, the winch 4 can be released. By rotating the threaded shaft 33, the distance between the crossbeam 34 and the sliding carriage 5 can be precisely adjusted, so that the belt body 3 maintains an ideal tension state.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The guide roller 7 is divided into a fixed roller 71 and a movable roller 72. The movable roller 72 is installed on the sliding carriage 5, and the fixed roller 71 is installed on the frame 1.

[0021] In practical applications, the belt body 3 first wraps around the fixed roller 71 and then winds around the moving roller 72. When the moving roller 72 moves, it can achieve a tensioning effect.
