Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a coal mine underground belt conveyor with an anti-deviation device. Background Technology

[0002] A belt conveyor consists of key components such as a conveyor belt, drive unit, rollers, idlers, tensioning device, and cleaning device. Its drive system is based on an electric motor, which drives the drive wheel (i.e., roller) through a reducer. The friction between the roller and the conveyor belt is used to propel the conveyor belt to run continuously.

[0003] Belt conveyors are a commonly used design for transporting coal in underground coal mines. However, due to the varying sizes and shapes of coal, the weight of coal on both sides of the conveyor belt differs. Furthermore, the material impacts the conveyor belt when it is placed on it. These factors result in uneven stress on the conveyor belt, causing it to tend to tilt in the direction of greater stress during operation. This leads to belt misalignment, which causes wear, tearing, and even breakage of the conveyor belt edges, increasing maintenance costs and affecting production. Therefore, a belt conveyor for underground coal mines with an anti-misalignment device is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a coal mine underground belt conveyor with an anti-deviation device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal mine underground belt conveyor with an anti-deviation device, comprising a conveyor support, with drive rollers rotatably connected to both ends of the inner wall of the conveyor support, a drive belt drivingly connecting adjacent sets of drive rollers, and a drive device fixed to one side of the conveyor support, and further comprising:

[0006] The straightening component, which is mounted on the conveyor support, is used to center the transmission belt;

[0007] The correction structure includes two pairs of fixed cylinders, which are respectively fixed to both sides of the inner wall of the conveyor support. The inner wall of the fixed cylinder is fitted with a connecting plate and a first spring. A movable rod is fixed to one side of the connecting plate. The end of the movable rod passes through the fixed cylinder and is fixed with a telescopic rod. Both the upper and lower ends of the telescopic rod are fixed with connecting frames. Several sets of rollers are rotatably connected inside the connecting frames. Several sets of sliding grooves are provided on the inner wall of the transmission belt.

[0008] As described above, the telescopic rod includes a sleeve, inside which a second spring and a movable shaft are fitted, and the bottom of the sleeve and the top of the movable shaft are respectively connected to two sets of connecting frames.

[0009] As described above, the roller extends into the interior of the groove and contacts the inner wall of the groove.

[0010] As mentioned above, one set of transmission rollers is connected to the output shaft of the drive device, and the middle part of the transmission roller is recessed inward.

[0011] As described above, the first spring is elastically supported between the fixed cylinder and the connecting plate.

[0012] As mentioned above, the second spring is elastically supported between the sleeve and the movable shaft.

[0013] Compared with existing technologies, this underground belt conveyor with anti-deviation device has the following advantages:

[0014] 1. When the transmission belt deviates, this utility model will push the roller to move to one side, thereby pulling the telescopic rod through the connecting frame to move the movable rod. At this time, the movable rod on one side will drive the connecting plate to compress the first spring. Therefore, through the elastic force of the first spring, the connecting plate will drive the movable rod to apply a pulling force to the telescopic rod, so that it uses the connecting frame to drive the roller to pull the slide groove, which is convenient for centering the transmission belt and preventing it from deviating.

[0015] Second, this utility model utilizes the elastic force of the first spring to move the connecting plate, thereby allowing the connecting plate to drive the movable rod to apply a pulling force to the telescopic rod, facilitating the control of the transmission belt to reset. When the transmission belt is pulled to reset, it will sway left and right, which can shake the coal above the transmission belt, thereby ensuring that the coal is evenly distributed and subjected to uniform force.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, this utility model provides a coal mine underground belt conveyor with an anti-deviation device, including a conveyor support 1, with drive rollers 3 rotatably connected to both ends of the inner wall of the conveyor support 1, a drive belt 4 drivingly connecting two adjacent sets of drive rollers 3, and a drive device 2 fixed to one side of the conveyor support 1, and also includes:

[0024] A straightening component, which is mounted on the conveyor support 1, is used to center the transmission belt 4.

[0025] The correction structure includes two pairs of fixed cylinders 5, which are fixed to both sides of the inner wall of the conveyor support 1. The inner wall of the fixed cylinder 5 is fitted with a connecting plate 12 and a first spring 7. A movable rod 6 is fixed to one side of the connecting plate 12. The end of the movable rod 6 passes through the fixed cylinder 5 and is fixed with a telescopic rod 8. Both the upper and lower ends of the telescopic rod 8 are fixed with connecting frames 9. Several sets of rollers 10 are rotatably connected inside the connecting frame 9. Several sets of sliding grooves 11 are provided on the inner wall of the transmission belt 4.

[0026] The telescopic rod 8 supports the two sets of connecting frames 9, which in turn drives the roller 10 to embed into the slide groove 11. When the transmission belt 4 is running, it will drive the roller 10 to rotate along the inner side of the connecting frame 9. When the transmission belt 4 deviates, it will push the roller 10 to move to one side. This allows the connecting frame 9 to pull the telescopic rod 8 and drive the movable rod 6 to move. At this time, the movable rod 6 on one side will drive the connecting plate 12 to compress the first spring 7. Therefore, through the elastic force of the first spring 7, the connecting plate 12 will drive the movable rod 6 to apply a pulling force to the telescopic rod 8, thereby resetting the transmission belt 4 and keeping it centered so that it does not deviate.

[0027] like Figure 2As shown, the telescopic rod 8 includes a sleeve 81, inside which a second spring 82 and a movable shaft 83 are fitted. The bottom of the sleeve 81 and the top of the movable shaft 83 are respectively connected to two sets of connecting frames 9.

[0028] The engagement between the sleeve 81 and the movable shaft 83 allows the movable shaft 83 to move along the inner side of the sleeve 81. The elastic force of the second spring 82 pushes the connecting frame 9 through the movable shaft 83 and the sleeve 81, causing the roller 10 to embed into the interior of the transmission belt 4, making it less likely to come off.

[0029] like Figure 3 , 4 As shown, the roller 10 extends into the interior of the groove 11 and contacts the inner wall of the groove 11.

[0030] Through the cooperation between the roller 10 and the transmission belt 4, since the roller 10 is in contact with the inner wall of the transmission belt 4, when the roller 10 moves, it will push the transmission belt 4 to move through the slide groove 11, which makes it easier to control the transmission belt 4 to reset.

[0031] like Figure 1 , 3 As shown, one set of transmission rollers 3 is connected to the output shaft of the drive device 2, and the middle part of the transmission rollers 3 is concave inward.

[0032] The design of the transmission roller 3, with its inward-curving center, facilitates coal accumulation in the middle of the transmission belt 4, effectively reducing the force difference between the two sides.

[0033] like Figure 2 As shown, the first spring 7 is elastically supported between the fixed cylinder 5 and the connecting plate 12.

[0034] The design of the first spring 7 enables the connecting plate 12 to have good elastic reset performance. Since the first spring 7 is in a compressed state, it will apply a spring force to the connecting plate 12. This will allow the connecting plate 12 to drive the movable rod 6 to apply a pulling force to the telescopic rod 8, which will facilitate the reset of the transmission belt 4. When the transmission belt 4 is pulled to reset, the elastic force of the first spring 7 will cause it to sway left and right, which will shake the coal above the transmission belt 4, thereby distributing the coal evenly and ensuring that it is subjected to uniform force.

[0035] like Figure 2 As shown, the second spring 82 is elastically supported between the sleeve 81 and the movable shaft 83.

[0036] The design of the second spring 82 allows a spring force to be applied to the movable shaft 83 and the sleeve 81, thereby driving the roller 10 to move through the connecting frame 9, which in turn makes the fit between the roller 10 and the slide groove 11 tighter.

[0037] Working principle:

[0038] First, the elastic force of the second spring 82 pushes the sleeve 81 and the movable shaft 83, causing the two sets of connecting frames 9 to move the rollers 10. This allows the rollers 10 to be embedded in the groove 11. When the transmission belt 4 deviates, it will push the rollers 10 to move to one side. This allows the connecting frame 9 to pull the telescopic rod 8, which in turn moves the movable rod 6. At this time, the movable rod 6 on one side will cause the connecting plate 12 to compress the first spring 7. Therefore, the elastic force of the first spring 7 will cause the connecting plate 12 to pull the movable rod 6, which will then exert a pulling force on the telescopic rod 8. This allows the connecting frame 9 to drive the rollers 10 to pull the groove 11, thus aligning the transmission belt 4 and preventing it from deviating.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
