Description

Technical Field

[0001] This utility model relates to the field of mining engineering technology, and more specifically to ore conveyors. Background Technology

[0002] Ore transport equipment is a general term for various equipment and systems used for transporting and transferring ore. The most common type is the belt conveyor. Its structure and principle mainly consist of components such as conveyor belt, drive drum, idler drum, idler roller, and tensioning device. By rotating the drive drum, the conveyor belt is driven to run by the friction between the conveyor belt and the drum, thereby realizing the continuous transport of ore on the conveyor belt.

[0003] In existing technologies, belt conveyor belts are prone to tilting during prolonged use, causing material to slip, resulting in losses and increased costs. Spilled material accumulates and requires cleanup, disrupting production and increasing the risk of slips and falls. Flexible mechanical return belt correction devices are commonly used to correct belt misalignment. These devices have specific components and flexible structures. In actual use, automated correction systems typically consist of multiple components, including sensors, controllers, and actuators. This complex system structure not only increases investment costs but also raises the system's failure rate. If any component malfunctions, it will affect the normal operation of the entire correction system, requiring professional technicians for repairs, which are costly and have limited applicability.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting up a support component, when the belt tilts, it will contact the pressure plate on the corresponding roller and drive the pressure plate to slide, which can increase the pressure inside the limiting groove, causing the top column to slide upward and drive the belt to gradually separate from the surface of the roller. Then the roller gradually returns to its original position, and the belt slides downward through friction. This cycle continues until the belt no longer contacts the pressure plate, and the belt correction is completed.

By setting the inclined groove with the opening facing downward on the surface of the roller, the friction between the belt and the roller can be increased, reducing the probability of belt deviation. At the same time, the friction can also improve the correction efficiency. Attached Figure Description

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] Specifically, the ore conveyor includes a belt conveyor body 1 and a belt 3 movably mounted on the belt conveyor body 1, with support components 2 installed at equal intervals at the connection between the belt conveyor body 1 and the belt 3;

[0023] Support assembly 2 includes a support base 21 fixedly connected to the surface of the belt conveyor body 1. A rotating plate 22 is rotatably connected to the center of the support base 21. A top seat 23 is fixedly connected to the top of the rotating plate 22. A support frame 24 is fixedly connected to the surface of the top seat 23. An exhaust pipe 26 is fixedly connected inside the support base 21. A limit groove 27 is formed inside the support base 21. A sealing plate 29 is slidably connected inside the limit groove 27. A spring 28 is fixedly connected to the bottom of the sealing plate 29. A top column 210 is fixedly connected to the surface of the spring 28. A connecting pipe 211 is fixedly connected inside the support base 21. A pressurizing assembly 25 is installed at the end of the connecting pipe 211 away from the support base 21. The pressurizing assembly 25 includes a... A roller 252 is rotatably connected to the support frame 24 via a bearing. A roller 251 is fixedly sleeved on the outer surface of the roller 252. A sealing groove 253 is equidistantly opened inside the roller 251. A piston rod 254 is slidably connected inside the sealing groove 253. A pressure plate 255 is fixedly connected to the end face of the piston rod 254. An air inlet pipe 256 and an air outlet pipe 257, which communicate with the inside of the sealing groove 253, are fixedly connected inside the roller 251. A connecting groove 2510 is opened inside the roller 252. A connecting pipe 258 is rotatably connected inside the roller 251 via a bearing. A sealing ring 259 is fixedly sleeved on the outer surface of the connecting pipe 258. The surface of the connecting pipe 258 is fixedly connected to the end face of the connecting pipe 211.

[0024] In this embodiment, by setting up the support component 2, when the belt 3 tilts, it will contact the pressure plate 255 on the corresponding roller 251 and drive the pressure plate 255 to slide, which can increase the pressure inside the limiting groove 27, causing the top column 210 to slide upward and drive the belt 3 to gradually separate from the surface of the roller 251. Then the roller 251 gradually returns to its original position and drives the belt 3 to slide downward through friction. This cycle continues until the belt 3 no longer contacts the pressure plate 255, at which point the belt 3 is corrected. This correction method does not require the participation of automated equipment, has low investment costs, greatly reduces the failure rate of the system, and also improves the safety of the belt conveyor body 1 during use.

[0025] Specifically, there are two limiting grooves 27 and two connecting pipes 211. The inside of the limiting groove 27 is connected to the inside of the connecting pipe 258 through the connecting pipe 211. One-way valves are fixedly installed inside the air inlet pipe 256 and the air outlet pipe 257. The outside of the roller 251 is connected to the inside of the sealing groove 253 through the one-way valve and the air inlet pipe 256. The inside of the air outlet pipe 257 is connected to the inside of the connecting pipe 258 through the one-way valve and the connecting groove 2510.

[0026] In this embodiment, by setting two one-way valves, when the piston rod 254 slides to the left, external air enters the sealing groove 253 through the air inlet pipe 256, while the air outlet pipe 257 is in a sealed state. When the piston rod 254 slides to the right, the air inside the sealing groove 253 enters the connecting groove 2510 through the air outlet pipe 257, while the air inlet pipe 256 is in a sealed state. Therefore, the process of the piston rod 254 sliding back and forth is the process of pressurizing the connecting groove 2510.

[0027] Specifically, the roller 251 is rotatably connected to the outer surface of the connecting pipe 258 by the sealing ring 259. The surface of the pressure plate 255 is arc-shaped. The surface of the roller 251 is provided with inclined grooves facing downward at equal intervals. The inner wall of the sealing groove 253 is fixedly connected with a silicone elastic block. The surface of the silicone elastic block abuts against the surface of the piston rod 254.

[0028] In this embodiment, by setting the surface of the pressure plate 255 to be arc-shaped, the belt 3 can be made to slide on the surface of the pressure plate 255. By setting the inclined groove with the opening facing downward on the surface of the roller 251, the friction between the belt 3 and the roller 251 can be increased, reducing the probability of the belt 3 running off-track. At the same time, the correction efficiency can also be improved through friction.

[0029] Specifically, the piston rod 254 is square, and a sealing ring is fixedly installed on the outer surface of the piston rod 254. The outer surface of the pressure plate 255 is slidably connected to the inside of the roller 251.

[0030] In this embodiment, since the piston rod 254 is square, it can limit the sliding of the pressure plate 255 and prevent the pressure plate 255 from rotating.

[0031] Specifically, under normal conditions, the tension of the spring 28 keeps the top seat 23 and the support seat 21 in a parallel state, and the inside of the limiting groove 27 is under strong pressure.

[0032] In this embodiment, the tension of the spring 28 and the strong pressure inside the limiting groove 27 can make the top seat 23 and the support seat 21 parallel.

[0033] The working principle and usage process of this utility model are as follows: During use, if the belt 3 deviates, the inner wall of the belt 3 will slide upward on the surface of the roller 251 and slowly contact the surface of the pressure plate 255. The rotation of the roller 251 causes the belt 3 to drive the pressure plate 255 to slide into the roller 251. The pressure plate 255 slides inside the sealing groove 253 via the piston rod 254. At this time, air inside the sealing groove 253 enters the limiting groove 27 through the exhaust pipe 257, the connecting groove 2510, the connecting pipe 258, and the connecting pipe 211. The limiting groove 27 is under high pressure, and the sealing plate 29 and the top column 210 drive the top seat 23 to rotate. The side of the sealing plate 29 seals the top of the exhaust pipe 26, thus the limiting groove 27 is sealed. When the top seat 23 rotates, the roller 251 continues to rise, and the sealing plate 29... After sliding upwards to a certain position, the top of the exhaust pipe 26 connects with the inside of the limiting groove 27, and the air inside the sealing groove 253 is released. At this time, through the tension of the spring 28, the top column 210 is quickly driven downwards by the sealing plate 29. At this time, through the strong pressure inside the limiting groove 27 on the opposite side, the top seat 23 is quickly reset and parallel to the support seat 21. During the rotation of the top seat 23, the friction between the inclined groove on the surface of the roller 251 and the belt 3 can drive the pressure plate to slide downwards and make the belt 3 separate from the surface of the pressure plate 255. After separating from the surface of the pressure plate 255, the belt 3 does not contact the pressure plate 255, and the top seat 23 and the support seat 21 are in a parallel state. If the belt 3 is not corrected after the above process is completed, and the surface of the belt 3 is still in contact with the surface of the roller 251, the above pressurization operation is repeated until the belt 3 no longer contacts the roller 251, at which point the belt 3 is completely corrected.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
