Description

Technical Field

[0001] This utility model relates to the field of material conveyor belt technology, and in particular to a sand and gravel conveyor belt correction device. Background Technology

[0002] With the increasing annual output of sand and gravel, the problems of material spillage, belt wear, and safety accidents caused by belt misalignment in traditional conveyor belts are becoming increasingly prominent. Existing belt alignment technologies have obvious shortcomings, such as slow response of mechanical guide rollers and complex maintenance of hydraulic systems. The industry urgently needs a high-precision and high-reliability intelligent belt alignment solution to meet the transportation requirements of sand and gravel and adapt to the harsh working conditions of mines. Therefore, it is necessary to design a belt alignment device for sand and gravel conveyors.

[0003] To address this issue, patent CN205633999U discloses a belt-correcting device for material conveyors, comprising a belt-correcting device body 8, a conveyor belt 4 and a limit switch 1 within the body 8, a travel switch 5 on each side of the conveyor belt 4, a first pressure roller 9 and a second pressure roller 10 on the upper surface of the conveyor belt 4, and an adjusting roller 3, higher than the first and second pressure rollers 10, on the lower surface of the conveyor belt 4 between the first and second pressure rollers 9 and 10, with a moving device connected to the adjusting roller 3; the travel switches 5 and the moving device are respectively connected to an adjustment control box 7. This invention has the beneficial effect of automatically correcting misaligned conveyor belts.

[0004] Although the aforementioned belt alignment device for material conveyor belts has the beneficial effect of automatically correcting belt deviations, the limit switch needs to physically contact the conveyor belt to be triggered during alignment, which makes it impossible to provide early warning of minor deviations and inconvenient to correct minor deviations in a timely manner. Therefore, it is necessary to design a belt alignment device for sand and gravel conveyor belts. Utility Model Content

[0005] The purpose of this utility model is to provide a sand and gravel conveyor belt correction device to solve the defects of existing sand and gravel conveyor belt correction devices. Although they have the beneficial effect of automatically correcting the misaligned conveyor belt, the limit switch needs to physically contact the conveyor belt to be triggered during correction, which cannot provide early warning of slight misalignment and makes it inconvenient to correct slight misalignment in a timely manner.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sand and gravel conveyor belt correction device, including a conveyor belt body;

[0007] Both sides of the inside of the conveyor belt body are provided with drive components, and a tensioning structure is provided at the middle position below the conveyor belt body.

[0008] Both sides of the conveyor belt body are provided with a limiting structure. The limiting structure includes vertical plates on both sides of the conveyor belt body. An electric push rod is fixed on the outer wall of the vertical plate away from the conveyor belt body. A linkage rod is fixed at the output end of the electric push rod. A limiting baffle is fixed at the end of the linkage rod close to the conveyor belt body. A guide slide rod is fixed at the corner position of the limiting baffle close to the vertical plate.

[0009] Monitoring structures are installed on the side of the conveyor belt body away from the vertical plate.

[0010] Furthermore, the drive assembly includes side plates, drive rollers, and drive motors. The drive rollers are all located on both sides inside the conveyor belt body, and side plates are provided at both ends of the drive rollers. The drive motor is fixedly installed on the outer wall of the top side of the side plate.

[0011] Furthermore, both ends of the drive rod are rotatably connected to the side plate, and the output end of the drive motor is fixedly connected to one end of the drive rod.

[0012] Furthermore, the guide slide rods are symmetrically distributed on both sides of the vertical plate, and the end of each guide slide rod away from the limiting baffle passes through the interior of the vertical plate and is slidably connected to the vertical plate.

[0013] Furthermore, the limiting baffles are symmetrically distributed on both sides of the conveyor belt body.

[0014] Furthermore, the monitoring structure includes a bracket, a mounting plate, a laser generator, and a laser receiver. The bracket is located on the side of the conveyor belt body away from the vertical plate. Mounting plates are fixed on the outer wall of the top of the bracket near the conveyor belt body. Laser generators are uniformly fixed on the outer wall of the mounting plate. Laser generators are fixed on the outer wall of one end of each laser generator.

[0015] Furthermore, each of the laser receivers is equipped with a microcontroller. The output end of the laser receiver and the input end of the electric push rod are electrically connected through the microcontroller. The input end of the laser receiver and the output end of the laser generator are also electrically connected through the microcontroller. The laser generators are evenly distributed on one side of the mounting plate.

[0016] Furthermore, the tensioning structure includes a base, an electric telescopic rod, and a mounting frame. The base is located below the conveyor belt body. Electric telescopic rods are fixed on both sides of the top of the base. Mounting frames are fixed on the top of the electric telescopic rods. Tensioning rollers are rotatably connected to the inner side of the mounting frames.

[0017] Furthermore, the top end of the tensioning roller and the bottom end of the conveyor belt body abut against each other.

[0018] The advantages of the gravel conveyor belt correction device provided by this utility model are as follows:

[0019] By setting a limiting structure, the running trajectory of the conveyor belt body can be restricted under the limiting action of the limiting baffle. Through mechanical limiting, the conveyor belt body can be corrected. The symmetrical design of the limiting baffle can realize bidirectional correction and limit slight deviations to avoid excessive deviation. This makes the device easy to correct the conveyor belt body, improving the convenience and service life of the sand and gravel conveyor belt correction device.

[0020] By incorporating a monitoring structure, the distance between the conveyor belt and the laser generator can be easily calculated through the laser emission and reception of the laser generator and laser receiver. This facilitates real-time detection of the conveyor belt's operating position. When the laser generator and laser receiver detect a change in distance, the operating status of the conveyor belt can be adjusted promptly. This enables the device to monitor the operating status of the conveyor belt in real time, improving the convenience and applicability of the sand and gravel conveyor belt correction device during use.

[0021] By incorporating a drive assembly and a tensioning structure, the rotation of the drive rollers provides stable power to the conveyor belt body, ensuring its continuous operation. Synchronous drive from both sides of the drive rollers reduces the risk of belt deviation. The tensioning rollers abut against the conveyor belt body from its bottom, maintaining tension during operation and preventing slippage. This reduces belt misalignment, enabling the device to easily drive and tension the conveyor belt, thus improving its convenience and efficiency in use. Attached Figure Description

[0028] 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.

[0029] Please see Figures 1-5 The present invention provides a sand and gravel conveyor belt correction device, which includes a conveyor belt body 1.

[0030] Reference Figures 1-5 The conveyor belt body 1 has drive components 2 on both sides inside. The drive components 2 include side plates 21, drive rollers 22 and drive motors 23. The drive rollers 22 are located on both sides inside the conveyor belt body 1. The two ends of the drive rollers 22 are provided with side plates 21. The drive motors 23 are fixedly installed on the outer wall of the top side of the side plates 21. The two ends of the drive rollers 22 are rotatably connected to the side plates 21. The output end of the drive motors 23 is fixedly connected to one end of the drive rollers 22. The tensioning structure 5 is located in the middle position below the conveyor belt body 1. The tensioning structure 5 includes a base 51, an electric telescopic rod 52 and a mounting frame 53. The base 51 is located below the conveyor belt body 1. The top two sides of the top of the base 51 are fixed with electric telescopic rods 52. The top of the electric telescopic rods 52 is fixed with mounting frames 53. The inner side of the mounting frames 53 is rotatably connected with tensioning rollers 54. The top of the tensioning rollers 54 abuts against the bottom of the conveyor belt body 1.

[0031] When an external power source is connected, the drive motor 23 is started. The start of the drive motor 23 will drive the drive roller 22 to rotate. The rotation of the drive roller 22 will drive the conveyor belt body 1 to move through friction. The side plate 21 supports the drive roller 22 and maintains its axial positioning. Then, the electric telescopic rod 52 is started. The extension and retraction of the electric telescopic rod 52 can drive the tensioning roller 54 to move closer to or away from the bottom end of the conveyor belt body 1. The extension and retraction distance of the electric telescopic rod 52 can be adjusted as needed to control the contact force between the tensioning roller 54 and the conveyor belt body 1, so as to avoid the tensioning force of the tensioning roller 54 on the conveyor belt body 1 being too large or too small, and to ensure the stability of the conveyor belt body 1 during operation.

[0032] Reference Figures 1-5 Both sides of the conveyor belt body 1 are provided with limiting structures 3. The limiting structures 3 include vertical plates 31 on both sides of the conveyor belt body 1. Electric push rods 33 are fixed on the outer wall of the side of the vertical plate 31 away from the conveyor belt body 1. Linkage rods 35 are fixed at the output end of the electric push rods 33. Limiting baffles 34 are fixed at the end of the linkage rods 35 near the conveyor belt body 1. Guide slide rods 32 are fixed at the corner position of the limiting baffles 34 near the vertical plate 31. The guide slide rods 32 are symmetrically distributed on both sides of the vertical plate 31. The end of the guide slide rod 32 away from the limiting baffle 34 passes through the interior of the vertical plate 31 and is slidably connected with the vertical plate 31. The limiting baffles 34 are symmetrically distributed on both sides of the conveyor belt body 1.

[0033] When the conveyor belt body 1 deviates during operation, the electric push rod 33 is activated. The electric push rod 33 will drive the limit baffle 34 to move closer to the side of the conveyor belt body 1. Under the restriction of the limit baffle 34, the two sides of the conveyor belt body 1 can be limited to prevent the conveyor belt body 1 from continuously deviating during operation. Under the restriction of the limit baffle 34, the conveyor belt body 1 cannot continue to deviate, so that the conveyor belt body 1 can gradually return to the correct track during operation and correct the deviation of the conveyor belt body 1 in a timely manner.

[0034] Reference Figures 1-5 A monitoring structure 4 is provided on the side of the conveyor belt body 1 away from the vertical plate 31. The monitoring structure 4 includes a bracket 41, a mounting plate 42, a laser generator 43, and a laser receiver 44. The bracket 41 is located on the side of the conveyor belt body 1 away from the vertical plate 31. The mounting plate 42 is fixed on the outer wall of the top of the bracket 41 near the side of the conveyor belt body 1. The laser generator 43 is uniformly fixed on the outer wall of the mounting plate 42. The laser generator 43 is fixed on the outer wall of one end of the laser generator 43. The laser receiver 44 is equipped with a microcontroller. The output end of the laser receiver 44 and the input end of the electric push rod 33 are electrically connected through the microcontroller. The input end of the laser receiver 44 and the output end of the laser generator 43 are electrically connected through the microcontroller. The laser generators 43 are evenly distributed on one side of the mounting plate 42.

[0035] When an external power supply is connected and the laser generator 43 is started, the laser generator 43 will emit a laser. The laser beam that hits the side of the conveyor belt body 1 will be reflected back. The laser receiver 44 will receive the reflected laser signal and calculate the distance between the laser generator 43 and the conveyor belt body 1 by the reception time. Multiple sets of laser generators 43 and laser receivers 44 can detect at the same time, which can effectively monitor whether the conveyor belt body 1 deviates during operation. When the distance between the laser generator 43 and the conveyor belt body 1 is abnormal, the laser generator 43 will control two sets of electric push rods 33 to start at the same time through the microcontroller. The limit baffle 34 restricts the two sides of the conveyor belt body 1 at one end of the drive motor 23 to avoid further deviation.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
