Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a device for preventing a coal mine conveyor from deviation. Background Art

[0002] The belt conveyors commonly used in coal mines are affected by geological conditions, inadequate maintenance, water and coal, and other factors, which make it easy for belt deviation accidents to occur during the production and transportation process. In addition, the conveyed coal and gangue will fall due to the influence of belt deviation. After the coal and gangue fall, they will rub against the belt for a long time, which makes it extremely easy for the belt to heat up and spontaneously combust, causing production safety accidents.

[0003] The anti-deviation device for coal mine conveyors operates as follows: A monitoring device equipped with components such as angle sensors monitors the position and status of the conveyor belt in real time. When the conveyor belt deviates, the roller carrier rotates, and the angle sensor measures the deviation angle and uploads the data. A signal collector processes the data and transmits it to the control center via a wireless transceiver. A correction device automatically adjusts the rollers based on the deviation angle to reset them. If the deviation exceeds a set threshold, the system issues an alarm and, in severe cases, delays the machine shutdown. Operators are required to regularly inspect the device and perform manual adjustments as necessary. Practical applications have shown that this device can reduce accident rates, improve operational efficiency, and ensure safe and stable conveyor operation.

[0004] However, existing anti-slip devices have certain drawbacks. Their fixed angles, with no adjustable inclusions, can lead to increased wear on components like rollers and conveyor belts, requiring more frequent replacement and increasing maintenance costs. Furthermore, the impact of falling material creates a force that, without a buffer, prevents the conveyor belt from effectively adjusting its lateral force when it slants. This significantly increases friction between the conveyor belt and the rollers and drums, leading to increased wear on the belt edges. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See also Figures 1-8The utility model provides an embodiment: a device for preventing a coal mine conveyor from running off the track, comprising a support frame 1; a mounting plate 21 and a transport assembly, the top of the support frame 1 is fixedly connected to a protective shell 4, the bottom of the support frame 1 is fixedly connected to an adjusting frame 5, the outside of the support frame 1 is fixedly connected to a side ladder 6, and a transport assembly is provided on the top of the support frame 1, the top of the support frame 1 is fixedly connected to a mounting plate 21, the outside of the mounting plate 21 is fixedly connected to a motor 22, the output end of the motor 22 is fixedly connected to a screw 23, the external thread of the screw 23 is connected to a sliding block 24, the inner side of the mounting plate 21 is fixedly connected to a limit rod 29, the internal rotation of the sliding block 24 is connected to a rotating plate 25, the inner side of the mounting plate 21 is fixedly connected to a cross plate 223, the top of the cross plate 223 is fixedly connected to a support rod 222, the internal rotation of the support rod 222 is connected to a bevel plate 26, the inner side of the bevel plate 26 is fixedly connected to a fixing frame 27, and the internal rotation of the fixing frame 27 is connected to The anti-deviation roller 28 and the screw rod 23 are fixedly connected to the pulley 210 on the outside, and the bolt 221 is provided inside the mounting plate 21. The buffer assembly is provided on the inner side of the mounting plate 21, and the buffer assembly includes a side plate 211, which is fixedly connected to the inner side of the mounting plate 21, and the outer side of the mounting plate 21 is fixedly connected to the connecting seat 212. The outer end of the side plate 211 away from the connecting seat 212 is fixedly connected to the fixing plate 213, and the inner side of the fixing plate 213 is fixedly connected to the sliding rod 218. The outer side of the fixing plate 213 is fixedly connected to the damper 215, and the outer side of the damper 215 is fixedly connected to the pushing block 216. The inner rotation of the pushing block 216 is connected to the rotating plate 220, and the outer end of the rotating plate 220 away from the pushing block 216 is rotatably connected to the buffer plate 219. The inner rotation of the buffer plate 219 is connected to the buffer roller 214. A spring 217 is provided at the middle position between the outer side of the fixing plate 213 and the outer side of the pushing block 216. The screw 23 is driven to rotate inside the mounting plate 21, so that the screw 23 drives the sliding block 24 to slide outside the limiting rod 29. At this time, the two sets of sliding blocks 24 drive the rotating plate 25 to move, and the rotating plate 25 pushes the bevel plate 26 to rotate inside the support rod 222, so that the bevel plate 26 drives the anti-deflection roller 28 inside the fixing frame 27 to adjust the angle. When the material falls, the anti-deflection roller 28 will move closer to the side plate 211, and the anti-deflection roller 28 will drive the buffer plate 219 to rotate inside the connecting seat 212. At this time, the buffer plate 219 drives the internal rotating plate 220 to approach the side plate 211. Driven by the buffer plate 219, the rotating plate 220 pushes the pushing block 216 to slide outside the sliding rod 218. At this time, the pushing block 216 cooperates with the spring 217 to buffer the pushing block 216 (the motor 22 on the device is reduced accordingly according to the corresponding situation. By adding a belt to the pulley 210 outside the screw 23, the devices are connected to each other, thereby alleviating the excessive use of the motor 22 and reducing costs).

[0025] See also Figure 2-6The first spring 217 is provided on the support 214 so that the spring 217 can move relative to the support 214, and the second spring 217 can move relative to the support 214.

[0026] See also Figure 7-8 In this embodiment, the transport component includes a motor 2 31, which is fixedly connected to the outside of the support frame 1, and the output end of the motor 2 31 is fixedly connected to a rotating disk 1 32, and the external transmission of the rotating disk 1 32 is connected to a rotating belt 33, and the end of the rotating belt 33 away from the rotating disk 1 32 is transmission-connected to a rotating disk 2 34, and the external part of the rotating disk 2 34 is fixedly connected to a transmission roller 1 35, and the external transmission of the transmission roller 1 35 is connected to a transmission belt 36, and the end of the transmission belt 36 away from the transmission roller 1 35 is transmission-connected to a transmission roller 2 37. Since the transmission belt 36 is provided, it is beneficial to transport materials; when the rotating disk 1 32 rotates, the rotating belt 33 will provide power to the rotating disk 2 34. Since the rotating belt 33 is provided, it is beneficial to make the rotating disk 1 32 and the rotating disk 2 34 rotate at the same time.

[0027] During operation, the motor 2 31 drives the rotating belt 33 outside the rotating disk 1 32 to rotate outside the rotating disk 2 34, so that the rotating disk 2 34 drives the conveyor belt 36 outside the conveyor roller 1 35 to rotate outside the conveyor roller 2 37, thereby transporting the coal falling on the top of the conveyor belt 36. The screw 23 is driven to rotate inside the mounting plate 21, so that the screw 23 drives the sliding block 24 to slide outside the limit rod 29. At this time, the two groups of sliding blocks 24 drive the rotating plate 25 to move, and the rotating plate 25 pushes the bevel plate 26 to rotate inside the support rod 222, so that the bevel plate 26 drives the anti-deflection roller 28 inside the fixed frame 27 to adjust the angle. When the material falls, the anti-deflection roller 28 will approach the side plate 211, and the anti-deflection roller 28 drives the buffer plate 219 to rotate inside the connecting seat 212. At this time, the buffer plate 219 drives the internal rotating plate 220 to approach the side plate 211. Driven by the buffer plate 219, the rotating plate 220 pushes the pushing block 216 to slide outside the sliding rod 218. At this time, the pushing block 216 cooperates with the spring 217 to buffer the pushing block 216.

[0028] Through the above steps, motor 1 22 drives screw 23 to rotate within mounting plate 21, driving slide block 24 to slide along limit rod 29. The two sets of slide blocks 24 move synchronously, pushing rotating plate 25, causing bevel plate 26 to rotate around support rod 222, thereby adjusting the angle of anti-skew roller 28 within fixed frame 27. When material falls, anti-skew roller 28 deflects toward side plate 211, thereby adjusting the device's anti-skew function. This drives buffer plate 219 to rotate within connecting seat 212. Buffer plate 219 drives rotating plate 220 to move synchronously, pushing push block 216 to slide along slide rod 218, with spring 217 providing buffering. This design reduces wear on rollers and conveyor belts, effectively adjusts the lateral deflection force of the conveyor belt, and reduces maintenance costs.
