Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically to a belt misalignment protection device. Background Technology

[0002] Belt conveyors are widely used in industries such as coal, metallurgy, power generation, pharmaceuticals, and food. As the main equipment for material transportation, they have strong continuous transportation capacity, high operating efficiency, and are easy to automate. However, during operation, belt conveyors inevitably experience belt misalignment, which leads to belt wear and material spillage, posing a great threat to safe operation.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a belt misalignment protection device to solve the technical problem that belt misalignment is prone to occur during the operation of belt conveyors in related technologies.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: A belt misalignment protection device is provided, applicable to belt conveyors. The belt conveyor includes a central idler roller for supporting the belt and a side idler roller located on one side of the central idler roller. The belt misalignment protection device includes: a detection component, installed on one side of the belt, used to detect the degree of belt misalignment; a correction component, including a rotatably mounted correction bracket and a drive mechanism, with the side idler roller mounted on the correction bracket, and the drive mechanism used to control the correction bracket to rotate around the length direction of the belt, the drive mechanism being signal-connected to the detection component; and a controller, which is signal-connected to both the drive mechanism and the detection component.

[0006] Furthermore, the drive mechanism includes a cylinder and a telescopic rod, which is telescopically oriented and connected to the side of the alignment bracket away from the belt to drive the alignment bracket to rotate.

[0007] Furthermore, multiple side rollers are installed on the belt alignment bracket, and these side rollers are spaced apart along the length of the belt.

[0008] Furthermore, the detection components include multiple components, which are spaced apart along the length of the belt; the correction components include multiple components, which are arranged one-to-one with the detection components.

[0009] Furthermore, multiple detection components and multiple correction components are installed on both sides of the belt.

[0010] Furthermore, the detection assembly includes a sidewall roller and a detector disposed corresponding to the side of the belt. The sidewall roller is rotatable. The detector includes a magnet and a sensor mounted on the sidewall roller, with the sensor corresponding to the position of the magnet.

[0011] Furthermore, the detector includes a counter, which is used to count the number of rotations of the sidewall roller.

[0012] Furthermore, the detection component includes a mounting bracket disposed on one side of the belt, on which a sidewall roller and a sensor disposed opposite to the sidewall roller are rotatably mounted.

[0013] Beneficial effects:

[0014] 1. With the above settings, the detection component detects the degree of belt misalignment and feeds the degree of misalignment back to the controller. When the belt misaligns, the belt conveyor is stopped and the misalignment is corrected by the correction component. The drive mechanism controls the correction bracket to rotate around the length of the belt, causing the side roller on the side of the belt misalignment to rotate. The side roller pushes the belt away from the misalignment side, thereby resetting the belt. This solves the technical problem of belt misalignment that easily occurs during the operation of belt conveyors in related technologies.

[0015] 2. In the belt misalignment protection device of this embodiment, by detecting the belt misalignment and correcting it in a timely manner, the detection and correction of belt misalignment are effectively guaranteed, thereby improving the coal flow production efficiency.

[0016] 3. Compared with traditional belt misalignment protection, the above-mentioned detection component detects belt misalignment by rotating the side roller driven by the belt when the belt misaligns. The material strength of the rotatable roller is much higher than that of the traditional probe spring detection structure, which greatly improves the reliability and durability of belt misalignment protection.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] According to an embodiment of this utility model, a belt misalignment protection device is provided. Please refer to [link / reference]. Figure 1 This device is applicable to belt conveyors, which include a central idler 10 for supporting the belt 1 and a side idler 20 located on one side of the central idler 10. The belt misalignment protection device includes: a detection component 2, which is installed on one side of the belt 1 and is used to detect the degree of belt misalignment; a correction component 3, which includes a rotatably mounted correction bracket 31 and a drive mechanism 32, on which the side idler 20 is mounted, and the drive mechanism 32 is used to control the correction bracket 31 to rotate around the length of the belt 1; and a controller, which is connected to the drive mechanism 32 and the detection component 2 respectively.

[0022] With the above settings, the detection component 2 detects the degree of belt misalignment of belt 1 and feeds the degree of misalignment back to the controller. When belt misalignment occurs, the belt conveyor is stopped and the belt is corrected by the correction component 3. The drive mechanism 32 controls the correction bracket 31 to rotate around the length of belt 1, causing the side roller 20 on the side of the belt misalignment to rotate. The side roller 20 pushes belt 1 to move away from the misalignment side, thereby resetting belt 1. This solves the technical problem of belt misalignment that easily occurs during the operation of belt conveyors in related technologies.

[0023] In the belt misalignment protection device of this embodiment, by detecting the misalignment of belt 1 and correcting it in a timely manner, the detection and correction of belt misalignment are effectively guaranteed, thereby improving the coal production efficiency.

[0024] In the belt misalignment protection device of this embodiment, see... Figure 1 The drive mechanism 32 includes a cylinder and a telescopic rod 321. The telescopic rod 321 is telescopically oriented and is connected to the side of the alignment bracket 31 away from the belt 1 to drive the alignment bracket 31 to rotate. Specifically, the drive mechanism 32 and the telescopic rod 321 are located below the side roller 20, and the extension and retraction of the telescopic rod 321 pushes the alignment bracket 31 to rotate.

[0025] In some embodiments, the drive mechanism may use a drive device such as a cylinder or an electric actuator.

[0026] In the belt misalignment protection device of this embodiment, see... Figure 1 Multiple side rollers 20 are mounted on the belt guide bracket 31, and the multiple side rollers 20 are spaced apart along the length of the belt 1. Specifically, the side rollers are modularized, so that a set of drive mechanisms can drive multiple side rollers 20 to rotate simultaneously, which simplifies the equipment structure and reduces costs.

[0027] In the belt misalignment protection device of this embodiment, see... Figure 1 The detection component 2 includes multiple components, which are spaced apart along the length of the belt 1. The correction component 3 also includes multiple components, which are arranged in a one-to-one correspondence with the detection components 2. In this way, the one-to-one correspondence between the correction components 3 and the detection components 2 allows for precise detection of the location where the belt 1 has deviated, and the belt position is controlled accordingly for correction and adjustment, thereby improving the correction efficiency.

[0028] In the belt misalignment protection device of this embodiment, see... Figure 1 Multiple detection components 2 and multiple correction components 3 are provided on both sides of the belt 1. In some embodiments, multiple detection components 2 and multiple correction components 3 are provided on both sides of the belt 1 so that when either side of the belt 1 deviates, it can be corrected in time.

[0029] It is understood that the belt misalignment protection device of this embodiment may also be used only on one side of the belt.

[0030] In the belt misalignment protection device of this embodiment, see... Figure 1 The detection component 2 includes a side roller 21 and a detector 22 that are arranged corresponding to the side of the belt 1. The side roller 21 is rotatable. The detector 22 includes a magnet 221 and a sensor 222 mounted on the side roller 21. The position of the sensor 222 corresponds to that of the magnet 221.

[0031] Specifically, sensor 222 is a magnetic sensor.

[0032] In the belt misalignment protection device of this embodiment, see... Figure 1 The detector 22 includes a counter, which is used to count the number of rotations of the sidewall roller 21.

[0033] Thus, when belt 1 deviates from its designated path, belt 1 comes into contact with side roller 21, causing side roller 21 to drive magnet 221 to rotate. When magnet 221 reaches the position corresponding to sensor 222, counter increments. When the set value is reached, counter itself changes from normally open to normally closed, sensor 222 outputs a 24V electrical signal, controller receives the 24V electrical signal, controller sends a stop signal, triggers deviation protection, belt conveyor stops, and after deviation is adjusted by correction component 3, the summation action returns the counter to zero, and belt conveyor can be restarted.

[0034] Compared with traditional belt misalignment protection, the detection component 2 described above detects belt misalignment by rotating the side roller 21 driven by the belt when the belt misaligns. The material strength of the rotatable roller is much higher than that of the traditional probe spring detection structure, which greatly improves the reliability and durability of belt misalignment protection.

[0035] In the belt misalignment protection device of this embodiment, see... Figure 1 The detection component 2 includes a mounting bracket 23, which is disposed on one side of the belt 1. A sidewall roller 21 and a sensor 222 opposite to the sidewall roller 21 are rotatably mounted on the mounting bracket 23. Specifically, the mounting bracket 23 is installed on the frame of the belt conveyor, and the mounting bracket 23 makes the sidewall roller 21 correspond to the side of the belt 1, thereby detecting belt deviation in a timely manner.

[0036] Understandably, the side roller 21 is tilted relative to its height to facilitate timely detection of belt misalignment.

[0037] The working process of the belt misalignment protection device in this embodiment is as follows:

[0038] The degree of belt misalignment is detected by the detection component 2. When belt 1 misaligns, it contacts the side roller 21, causing the side roller 21 to drive the magnet 221 to rotate. When the magnet 221 reaches the position corresponding to the sensor 222, the counter increments. When the set value is reached, the counter changes from normally open to normally closed, and the sensor 222 outputs a 24V electrical signal. The controller receives the 24V electrical signal and sends a stop signal, triggering the misalignment protection. The belt conveyor stops and the belt is corrected by the correction component 3. The drive mechanism 32 controls the correction bracket 31 to rotate around the length of belt 1, causing the side roller 20 on the side of the belt misalignment to rotate. The side roller 20 pushes the belt 1 away from the misalignment side, thus resetting the belt 1. After the belt is corrected by the correction component 3, the summation action resets the counter to zero, and the belt conveyor can be restarted.
