Description

Technical Field

[0001] This utility model relates to the field of coal conveyor belt deviation adjustment technology, specifically a coal conveyor belt anti-deviation adjustment mechanism. Background Technology

[0002] Coal sampling requires the use of belt conveyors to transport the coal. Belt conveyors are a common type of coal conveying equipment, capable of efficiently transporting coal from one location to another. They mainly consist of a conveyor belt, conveyor rollers, a drive unit, and idlers. Their advantages include long conveying distances, high conveying capacity, and stable operation, making them suitable for large-volume, long-distance conveying applications. However, due to the long length of the coal conveyor belt and the presence of multiple sets of conveyor rollers, uneven stress and coal drop points can easily cause the conveyor belt to shift, leading to coal falling during subsequent transport and affecting conveying efficiency. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a coal conveyor belt anti-deviation adjustment mechanism.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a coal conveyor belt anti-deviation adjustment mechanism, including a bracket, wherein two sets of brackets are symmetrically arranged, and a first base is provided vertically and horizontally between the two brackets. A second base is fixedly installed on both sides of the first base on the two brackets. First conveying rollers are fixedly arranged at both ends of the upper surface of the first base and the second base, and are inclined and symmetrically distributed. A second conveying roller is rotatably arranged between the two first conveying rollers on the first base and the second base. A conveyor belt is provided between the first conveying rollers and the second conveying rollers. A base plate is fixedly provided between the brackets below the first base. A vertically arranged drive shaft is rotatably arranged at the middle end of the base plate. The top of the drive shaft is fixedly arranged on the first base. A drive motor is fixedly arranged on the lower surface of the base plate near the drive shaft. The output end of the drive motor is connected to the drive motor. A fixing block is fixedly arranged on the side wall of the bracket facing the conveyor belt. A vertically arranged contact sensor is fixedly arranged on the fixing block. The contact sensor is electrically connected to the drive motor.

[0005] Preferably, a worm gear is fixedly provided at the bottom of the drive shaft, and a worm is meshed and connected to the worm gear; a protective cover is fixedly provided on the lower surface of the base plate near the worm gear and the worm, and the worm gear, the worm, and the bottom of the drive shaft are all rotatably disposed within the protective cover; a vertically arranged infrared monitoring tube is installed at the end of the fixed block away from the bracket, and the infrared monitoring tube is also electrically connected to the drive motor.

[0006] Preferably, the second base has a positioning groove at its end, and a fixing bolt is inserted into the positioning groove to fix it to the bracket.

[0007] Preferably, the first base and the plurality of second bases are distributed at equal intervals, and a set of first bases is arranged between the plurality of second bases.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. When the conveyor belt is subjected to external force and deviates from its normal track and comes into contact with the contact sensor on the side wall, the contact sensor will send an electrical signal to the drive motor. After the drive motor starts, it drives the worm, worm wheel, drive shaft and the first base to rotate, thereby causing the conveyor rollers on the first base and the second base to move the entire conveyor belt back to the normal track. It can automatically adjust the belt that deviates in real time without manual intervention, effectively solving the problem of belt deviation and reducing the coal falling due to belt deviation.

[0010] 2. The infrared monitoring tube at the end of the fixed block emits infrared rays to form a monitoring range. When the conveyor belt is adjusted by the first base to move into the range formed by the two infrared monitoring tubes, it indicates that the conveyor belt is within the normal working path threshold. This precise monitoring method can ensure that the conveyor belt always operates within a reasonable range, further improving the accuracy and stability of coal transportation and ensuring transportation efficiency.

[0016] 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.

[0017] Example: Figure 1-3 As shown, this utility model provides a coal conveyor belt anti-deviation adjustment mechanism, including a bracket 1. Two sets of brackets 1 are symmetrically arranged. A first base 11, vertically and horizontally positioned, is provided between the two brackets 1. Second bases 12 are fixedly installed on both sides of the first base 11 on the two brackets 1. First conveying rollers 2, inclined and symmetrically distributed, are fixedly installed at both ends of the upper surfaces of the first base 11 and the second base 12. A second conveying roller 21 is rotatably mounted on the first base 11 and the second base 12 between the two first conveying rollers 2. A conveyor belt 4 is provided between the brackets 1 and a base plate 22 is fixedly provided below the first base 11. A vertically arranged drive shaft 23 is rotatably provided at the middle end of the base plate 22. The top of the drive shaft 23 is fixedly provided on the first base 11. A drive motor 26 is fixedly provided on the lower surface of the base plate 22 near the drive shaft 23. The output end of the drive motor 26 is connected to the drive motor 26. A fixing block 3 is fixedly provided on the side wall of the bracket 1 facing the conveyor belt 4. A vertically arranged touch sensor 31 is fixedly provided on the fixing block 3. The touch sensor 31 is electrically connected to the drive motor 26.

[0018] A worm gear 24 is fixedly provided at the bottom of the drive shaft 23. A worm 25 is meshed on the worm gear 24. Driven by the worm 25 and the worm gear 24, the stop between the adjusted drive shaft 23 and the first base 11 can be increased to prevent reverse rotation and thus prevent unclear adjustment.

[0019] A protective cover 27 is fixedly installed on the lower surface of the base plate 22 near the worm gear 24 and worm 25. The bottom of the worm gear 24, worm 25 and drive shaft 23 are all rotatably installed inside the protective cover 27. The protective cover 27 mainly protects the worm gear 24, worm 25 and drive shaft 23 to prevent a large amount of impurities in the mine from causing the worm gear 24 and worm 25 to not rotate normally.

[0020] An infrared monitoring tube 32 is installed vertically at the end of the fixed block 3 away from the bracket 1. The infrared monitoring tube 32 is also electrically connected to the drive motor 26. When the misaligned conveyor belt 4 is moved back between the two infrared monitoring tubes 32, the conveyor belt 4 is within the normal working path threshold and is transporting coal normally. This structure is used to detect whether the adjusted conveyor belt 4 has been adjusted to the target position. If the infrared light on one side is still blocked, it means that it has not been adjusted correctly and the drive motor 26 still needs to be started to continue the adjustment.

[0021] The second base 12 has a positioning groove 13 at its end. A fixing bolt is inserted into the positioning groove 13 and fixedly connected to the bracket 1. The fixing bolt is inserted into the positioning groove 13 to make the second base 12 and the bracket 1 stably fixed, which facilitates the quick installation of the second base 12 and also ensures the stability of the second base 12 on the bracket 1.

[0022] The first base 11 and multiple second bases 12 are evenly spaced and a set of first bases 11 is set between the multiple second bases 12. The multiple first bases 11 are inserted into the second bases 12 at equal intervals, so that when each section of the conveyor belt 4 runs off-center, it can be adjusted in time.

[0023] Working principle: The conveyor belt 4 is positioned between the first conveyor roller 2 and the second conveyor roller 21, forming an inverted trapezoidal shape to ensure stable coal transport. When the conveyor belt 4 deviates due to external force, it contacts the side contact sensor 31. Both sides of the conveyor belt 4 are electrically connected to the drive motor 26. When contact is made with one side of the sensor 31, the sensor generates an electrical signal, which starts the drive motor 26. The drive motor 26 then drives the worm gear 25 to rotate, which in turn drives the worm wheel 24 to rotate. The drive shaft 23 and the first base 11 fixed at the top are rotated. When the conveyor belt 4 deviates to the left, the drive motor 26 will drive the first base 11 to rotate clockwise to the right. When the second base 12 rotates to the right, the first conveyor roller 2 and the second conveyor roller 21 on the first base 11 will move the conveyor belt 4 as a whole to the normal track. At the same time, the infrared monitoring tube 32 fixed at the end of the fixed block 3 emits infrared rays. When the conveyor belt 4 is adjusted by the first base 11 to move into the interval formed by the two infrared monitoring tubes 32, the conveyor belt 4 is within the normal working path threshold and the conveyor belt 4 transports coal normally.

[0024] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
