Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment, and specifically relates to a deviation limit protection device for a coal preparation belt conveyor. Background Technology

[0002] Belt conveyors, also known as belt conveyors, are continuous conveying equipment widely used in industries such as mining, metallurgy, coal, ports, power, and chemicals. However, belt misalignment is a common problem in coal preparation belt conveyors. This can stem from poor belt quality or debris between the belt and rollers. Once the belt misaligns, material can easily spill, causing material loss and potentially polluting the working environment. Spilled material accumulating around the conveyor can even affect the normal operation of the equipment. Conventional solutions include checking and cleaning coal sludge or debris from the rollers and idlers, inspecting and cleaning any coal accumulation on the belt, and addressing different types of misalignment such as remaking joints, adjusting belt tension for unpredictable misalignment, and adjusting the coal drop point or adding idlers if the belt is not misaligned under load. However, these methods have obvious drawbacks. They require frequent manual inspection and adjustment, and cannot be monitored and automatically corrected in real time. They cannot fundamentally prevent deviation and cannot guarantee that the belt will run stably on the normal track. In severe cases, they may lead to increased belt wear, tearing, or even shutdown, affecting coal preparation production efficiency and economic benefits. Therefore, a new structure is needed to solve the above technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a deviation limiting protection device for a coal preparation belt conveyor, and solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a deviation limiting protection device for a coal preparation belt conveyor, comprising: a conveying component, a limiting component, and a deviation component. The upper surface of the conveying component is equipped with a limiting component for preventing goods from running off-center, and the upper surface of the conveying component is equipped with a deviation component for belt deviation. The conveying component includes a conveyor belt for conveying goods, and the lower surface of the conveyor belt is equipped with an installation component. The limiting component includes an installation rod for installing a guardrail, and the deviation component includes a deviation roller for limiting the belt deviation.

[0005] In a preferred embodiment, the mounting assembly includes a mounting frame and a support frame. A mounting frame is mounted on the left and right surfaces of the conveyor belt, and multiple pairs of mounting frames are mounted on the left edge and right surface of the lower surface of the mounting frame.

[0006] In a preferred embodiment, the height of the multiple mounting frames gradually decreases, a drive motor for powering the conveyor belt is mounted on the right side surface of the conveyor belt, and the conveyor belt is installed inside the mounting frame.

[0007] In a preferred embodiment, multiple mounting rods are evenly installed on the left and right surfaces of the mounting frame, and railings are horizontally installed on the outer surfaces of the mounting rods. The diameter of the railings matches the diameter of the mounting rods. In use, the railings can act as a barrier during the transport of goods, restricting the position of the goods on the belt conveyor and preventing them from falling off due to various reasons, thereby reducing the loss of goods and the impact on the working environment.

[0008] In a preferred embodiment, the length of the railing matches the inclined length of the conveyor belt, and a gap is provided between the side of the conveyor belt and the mounting frame.

[0009] In a preferred embodiment, the misalignment roller has an hourglass shape, and multiple sets of misalignment components are provided. The multiple sets of misalignment components have the same structure. The misalignment component also includes a rotating column, and a misalignment roller is rotatably mounted on the upper surface of each rotating column. In use, the misalignment roller is in close contact with the belt. When the belt tends to deviate, the misalignment roller can apply a lateral force to the belt through its own rotation, so that the belt returns to the normal operating position, thereby correcting the belt and effectively preventing the belt misalignment from worsening.

[0010] In a preferred embodiment, the diameter of the rotating column is greater than the gap length between the conveyor belt and the mounting frame, the misalignment roller is installed between the conveyor belt and the mounting frame via the rotating column, and the lower surface of the misalignment roller is lower than the upper surface of the conveyor belt.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a limiting component, the upper surface of the conveying component is equipped with a limiting component for preventing goods from running away. The limiting component includes an installation rod for installing a railing. When in use, the railing can play a blocking role in the process of conveying goods, limiting the position of the goods on the belt conveyor, preventing them from running away and falling due to various reasons, reducing the loss of goods and the impact on the working environment.

[0012] 2. By setting up a belt misalignment component, the upper surface of the conveyor component is equipped with a belt misalignment component. The belt misalignment component includes a belt misalignment roller for limiting belt misalignment. During use, the belt misalignment roller is in close contact with the belt. When the belt shows a tendency to deviate, the belt misalignment roller can apply a lateral force to the belt through its own rotation, so that the belt returns to the normal operating position, thereby correcting the belt misalignment and effectively preventing the belt misalignment from worsening.

[0021] 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.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a deviation limiting protection device for a coal preparation belt conveyor, comprising: a conveying component, a limiting component, and a deviation component. The upper surface of the conveying component is equipped with a limiting component for preventing goods from running off-center, and the upper surface of the conveying component is equipped with a deviation component for belt deviation. The conveying component includes a conveyor belt 220 for conveying goods, and an installation component is installed on the lower surface of the conveyor belt 220. The limiting component includes an installation rod 300 for installing a guardrail 310, and the deviation component includes a deviation roller 410 for limiting the belt deviation.

[0023] Please see Figures 1 to 3 As the first embodiment of this utility model: the installation component includes a mounting frame 100 and a support frame 110. A mounting frame 200 is installed on the left and right surfaces of the conveyor belt 220, and multiple pairs of mounting frames 100 are installed on the left edge and right surface of the lower surface of the mounting frame 200.

[0024] The height of multiple mounting frames 100 gradually decreases, and a drive motor 210 for powering the conveyor belt 220 is installed on the right side surface of the conveyor belt 220. The conveyor belt 220 is installed inside the mounting frame 200.

[0025] Multiple mounting rods 300 are evenly mounted on the left and right surfaces of the mounting frame 200. A railing 310 is horizontally mounted on the outer surface of the mounting rod 300, and the diameter of the railing 310 matches the diameter of the mounting rod 300.

[0026] The length of the railing 310 matches the inclined length of the conveyor belt 220, and a gap is provided between the side of the conveyor belt 220 and the mounting frame 200.

[0027] When in use, the user first places the coal block to be transported on the upper surface of the conveyor belt 220. When transporting the coal block, the mounting rods 300 on the left and right surfaces of the conveyor belt 220, together with the guardrails 310, can limit the transported coal block (the size of the transported coal block must be higher than the height of the guardrails 310, but the user can install the guardrails 310 at different heights on the outer surface of the mounting rods 300 according to the actual use situation for user convenience). During use, the guardrails 310 can act as a barrier during the transport of goods, limiting the position of the goods on the belt conveyor, preventing them from deviating and falling due to various reasons, reducing the loss of goods and the impact on the working environment.

[0028] Please see Figures 1 to 3 As a second embodiment of the present invention: the misalignment roller 410 has an hourglass-shaped structure, and multiple sets of misalignment components are provided. The multiple sets of misalignment components have the same structure. The misalignment component also includes a rotating column 400, and a misalignment roller 410 is rotatably installed on the upper surface of each rotating column 400.

[0029] The diameter of the rotating column 400 is greater than the gap length between the conveyor belt 220 and the mounting frame 200. The misalignment roller 410 is installed between the conveyor belt 220 and the mounting frame 200 through the rotating column 400. The lower surface of the misalignment roller 410 is lower than the height of the upper surface of the conveyor belt 220.

[0030] In use, when the conveyor belt 220 is operated according to the steps of the first embodiment, the conveyor belt 220 will abut against the deviation roller 410 on the upper surface of the mounting frame 200. When the conveyor belt 220 deviates from its original position, the deviation roller 410 will actually abut against the conveyor belt 220 over a large area. Since the deviation roller 410 has an hourglass structure, it provides a lateral force to the conveyor belt 220, thereby returning the conveyor belt 220 to its original position. The above steps are repeated when the conveyor belt 220 is running, thereby achieving the effect of correcting the deviation of the conveyor belt 220. When combined with the limiting component, it can provide a limiting effect on the goods and the conveyor belt 220, making it convenient for users. Since the deviation roller 410 is in close contact with the belt during use, when the belt tends to deviate, the deviation roller 410 can apply a lateral force to the belt through its own rotation, so that the belt returns to the normal operating position, thereby correcting the belt and effectively preventing the belt deviation from worsening.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
