Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt conveyor deviation correction device for coal mines. Background Technology

[0002] A belt conveyor is a device used in coal mine production and transportation to transport coal from one place to another. It typically consists of a belt conveyor, drive unit, tensioning device, rollers, support frame, etc., and has the advantages of high conveying efficiency, good stability, and strong adaptability.

[0003] Utility model CN211495643U discloses a belt conveyor for coal mines. The key technical features include a frame, support legs, and a motor. Support legs are installed at the bottom of the frame, and hanging feet are installed at the bottom of each support leg. A controller is installed on one side of the frame, and a conveyor belt is installed inside the frame. An auxiliary belt is installed at the top of the conveyor belt, and pins are installed at both ends of the auxiliary belt. A motor is installed at one end of the frame, and a power roller is installed at the output end of the motor. A square column is installed on one side of the power roller. A connecting box is installed at one end of the frame, and a controller is also installed at one end of the frame. The output end of the controller is electrically connected to the input end of the motor via a wire. This utility model, by installing a frame, support legs, and a motor, and installing connecting strips at both ends of the auxiliary belt, allows for easy replacement of the auxiliary belt. If the conveyor belt becomes slack, a shorter auxiliary belt can be replaced, greatly improving efficiency.

[0004] Regarding the above-mentioned issues, the following technical defects exist: Coal mine belt conveyors are devices used in coal mine production and transportation to transport coal from one place to another. Conveyors have advantages such as high conveying efficiency, good stability, and strong adaptability. However, a drawback of conveyors is that during long-term operation, the conveyor belt on its surface may deviate due to factors such as uneven load, mechanical wear, and improper equipment adjustment. This deviation can lead to the accumulation of coal and mineral materials, exacerbate the deviation, or damage the conveyor belt, thus affecting the normal operation of coal mine transportation.

[0005] Therefore, it is necessary to provide a new device for correcting belt conveyor misalignment in coal mines to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address a shortcoming in existing conveyors: during long-term operation, the conveyor belt may deviate due to uneven load, mechanical wear, improper equipment adjustment, or other factors. This deviation can lead to coal and mineral accumulation, further deviance, or damage to the conveyor belt, thus affecting the normal operation of coal transportation.

[0007] To solve the above-mentioned technical problems, this utility model provides a belt conveyor deviation correction device for coal mines, comprising: a support frame, a conveyor body mounted on the upper surface of the support frame, a correction mechanism provided on the side of the support frame, the correction mechanism comprising four support plates, the four support plates being respectively installed at both ends of the support frame, a connecting plate being fixedly connected to one side of the support plate, a cylinder being fixedly connected to one side of the connecting plate, a push rod being fixedly connected to the output end of the cylinder, a contact plate being fixedly connected to the end of the push rod away from the cylinder's arc surface, an assembly plate being fixedly connected to the side of the support plate near the conveyor body, a central controller being fixedly connected to the side of the assembly plate away from the support plate, and a vision sensor being fixedly connected to the side of the assembly plate near the central controller.

[0008] The aforementioned components achieve the following effects: The coal mine belt conveyor is a device used in coal mine production and transportation to transport coal from one place to another. The conveyor body has advantages such as high conveying efficiency, good stability, and strong adaptability. However, a drawback of the conveyor body is that during long-term operation, the conveyor belt on its surface may deviate due to uneven load, mechanical wear, improper equipment adjustment, and other factors. This deviation can lead to coal and material accumulation, exacerbated deviation, or belt damage, affecting the normal operation of coal transportation. When the conveyor belt on the conveyor body deviates, a correction mechanism can be used to squeeze the surface of the conveyor belt. This squeezing adjusts the movement angle of the conveyor belt, thereby improving the stability of the conveyor belt during transportation, ensuring smooth coal transport, and extending the service life of the entire conveyor body.

[0011] Preferably, a contact pad is fixedly connected to one side of the contact plate, and the cross-sectional dimensions of the contact pad are the same as those of the contact plate.

[0012] The effect achieved by the above components is that the contact pad can reduce wear on the surface of the contact plate.

[0013] Preferably, the push rod is a titanium alloy rod.

[0014] The effect achieved by the above components is that the surface of the push rod made of titanium alloy is less prone to rust, resulting in better performance.

[0015] Preferably, a cleaning mechanism is provided on one side of the inner wall of the bracket. The cleaning mechanism includes a motor, one side of which is fixedly connected to one side of the inner wall of the bracket. A rotating rod is fixedly connected to the output end of the motor. An adjusting plate is threadedly connected to the arc surface of the rotating rod. Two guide rods slide through one inner wall of the adjusting plate. The two ends of the arc surface of the guide rods are fixedly connected to the two sides of the inner wall of the bracket, respectively. A cleaning plate is slidably connected to the other inner wall of the adjusting plate. Two positioning rods threaded through the inner wall of the adjusting plate are threadedly connected to the inner wall of the cleaning plate.

[0016] The effect achieved by the above components is that when using the conveyor body to transport coal, the cleaning mechanism can be used to clean the surface of the conveyor belt of the conveyor body, thereby preventing coal debris from accumulating on the conveyor body, affecting the efficiency of the conveyor body in transporting coal, and improving the service life of the conveyor body.

[0017] Preferably, an auxiliary block is fixedly connected to one end of the arc surface of the positioning rod, and the cross-section of the auxiliary block is funnel-shaped.

[0018] The effect achieved by the above components is that the auxiliary block can increase the speed at which the positioning rod connects to the inner wall of the adjusting plate.

[0019] Preferably, a plurality of anti-slip grooves are provided at the other end of the arc surface of the positioning rod, and the plurality of anti-slip grooves are evenly distributed on the arc surface of the positioning rod.

[0020] The effect achieved by the above components is that the anti-slip groove can increase the friction on the surface of the positioning rod.

[0021] Compared with related technologies, the belt conveyor deviation correction device for coal mines provided by this utility model has the following beneficial effects:

[0022] This utility model provides a belt conveyor deviation correction device for coal mines. By setting a correction mechanism, when the conveyor belt is found to be deviating due to factors such as uneven load, mechanical wear, or improper equipment adjustment during the use of the conveyor, the correction mechanism can squeeze both sides of the conveyor belt to correct its position and prevent coal and mineral materials from accumulating, the deviation from becoming more severe, or the conveyor belt from being damaged.

[0023] By setting up a cleaning mechanism, when using a conveyor to transport coal in a mine, the cleaning mechanism can clean the debris accumulated on the surface of the conveyor belt, thereby improving the cleanliness of the conveyor surface and preventing a large amount of debris from accumulating on the conveyor, which would affect the conveyor's transmission efficiency and service life.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 6The present invention provides a coal mine belt conveyor deviation correction device, comprising: a support 1, a conveyor body 4 mounted on the upper surface of the support 1, a correction mechanism 2 provided on the side of the support 1, and a cleaning mechanism 3 provided on one side of the inner wall of the support 1.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 4 The correction mechanism 2 includes four support plates 201, which are respectively installed at both ends of the bracket 1. A connecting plate 202 is fixedly connected to one side of the support plate 201, and a cylinder 203 is fixedly connected to one side of the connecting plate 202. A push rod 204 is fixedly connected to the output end of the cylinder 203. A contact plate 205 is fixedly connected to the end of the push rod 204 away from the arc surface of the cylinder 203. An assembly plate 206 is fixedly connected to the side of the support plate 201 closest to the conveyor body 4, and a central controller 207 is fixedly connected to the side of the assembly plate 206 away from the support plate 201. A vision sensor 208 is fixedly connected to the side of the assembly plate 206 near the central controller 207. The coal mine belt conveyor body 4 is a device used in coal mine production and transportation to transport coal from one place to another. The conveyor body 4 has advantages such as high conveying efficiency, good stability, and strong adaptability. However, the conveyor body 4 has a drawback: during long-term operation, the conveyor belt on its surface may deviate due to uneven load, mechanical wear, improper equipment adjustment, and other factors. A misaligned conveyor belt can cause coal and mineral materials to accumulate, worsen the misalignment, or damage the conveyor belt, affecting the normal operation of coal transportation. When the conveyor belt on the conveyor body 4 misaligns, the correction mechanism 2 can press the surface of the conveyor belt to adjust its movement angle, thereby improving the stability of the conveyor belt during transportation and the smoothness of the coal transportation process, and extending the service life of the entire conveyor body 4. A mounting plate 210 is fixedly connected to the support plate 201 near the bracket 1, and two screws pass through the inner thread of the mounting plate 210. 211, both screws 211 are threaded to the inner wall of bracket 1. When maintenance of the correction mechanism 2 is required, the entire correction mechanism 2 can be disassembled by rotating the screws 211 in the mounting plate 210, which facilitates maintenance. A contact pad 209 is fixedly connected to one side of the contact plate 205. The cross-sectional dimensions of the contact pad 209 are the same as those of the contact plate 205. The contact pad 209 can reduce the wear on the surface of the contact plate 205. The push rod 204 is a titanium alloy rod. The surface of the titanium alloy push rod 204 is less prone to rust and has a better performance.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The cleaning mechanism 3 includes a motor 31. One side of the motor 31 is fixedly connected to one side of the inner wall of the support 1. A rotating rod 32 is fixedly connected to the output end of the motor 31. An adjusting plate 33 is threadedly connected to the arc surface of the rotating rod 32. Two guide rods 34 slide through one inner wall of the adjusting plate 33. The two ends of the arc surface of the guide rods 34 are fixedly connected to the two sides of the inner wall of the support 1, respectively. A cleaning plate 35 is slidably connected to the other inner wall of the adjusting plate 33. Two positioning rods 36 threaded through the inner wall of the adjusting plate 33 are threaded through the inner wall of the cleaning plate 35. When the conveyor body 4 is used to transport coal, The cleaning mechanism 3 can be used to clean the surface of the conveyor belt of the conveyor body 4, thereby preventing coal debris from accumulating on the conveyor body 4, affecting the efficiency of the conveyor body 4 in transporting coal, and improving the service life of the conveyor body 4. An auxiliary block 38 is fixedly connected to one end of the arc surface of the positioning rod 36. The cross section of the auxiliary block 38 is funnel-shaped. The auxiliary block 38 can improve the speed of connection between the positioning rod 36 and the inner wall of the adjusting plate 33. Several anti-slip grooves 37 are opened at the other end of the arc surface of the positioning rod 36. Several anti-slip grooves 37 are evenly distributed on the arc surface of the positioning rod 36. The anti-slip grooves 37 can improve the friction of the surface of the positioning rod 36.

[0036] The working principle of the belt misalignment correction device for a coal mine belt conveyor provided by this utility model is as follows: When the conveyor belt on the conveyor body 4 misaligns, the vision sensor 208 transmits the misalignment signal to the central controller 207 on the assembly plate 206. The central controller 207 activates the cylinder 203 installed on the connecting plate 202. The movement of the cylinder 203 drives the push rod 204 to move through the output end. The movement of the push rod 204 drives the contact plate 205 to move in the direction of the conveyor belt. At this time, the contact plate 205 can squeeze the surface of the misaligned conveyor belt, thereby correcting the angle of the conveyor belt.

[0037] Slide the cleaning plate 35 into the adjusting plate 33. The cleaning plate 35 can then be fixed on the adjusting plate 33 by the positioning rod 36. Start the motor 31. The movement of the motor 31 will drive the rotating rod 32 to move through the output end. The movement of the rotating rod 32 will drive the adjusting plate 33 to slide along the direction of the guide rod 34. At this time, the surface of the conveyor belt of the conveyor body 4 can be cleaned by the cleaning plate 35 installed on the adjusting plate 33.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
