Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to an anti-slip device for conveyor belts. Background Technology

[0002] Conveyor belts are widely used in mining, docks, power plants, metallurgy, and manufacturing industries as efficient material handling equipment in industrial production and logistics transportation. However, in actual operation, conveyor belts often experience tension fluctuations due to load changes, environmental factors (such as temperature and humidity changes), and mechanical wear, leading to belt slippage. Belt slippage not only affects material handling efficiency but can also cause equipment damage, increased energy consumption, and even affect production safety.

[0003] Traditional conveyor belt tensioning methods mainly include spring tensioning, hydraulic tensioning, and counterweight tensioning. Among these, counterweight tensioning devices are widely used due to their simple structure, strong automatic adjustment capability, and low maintenance cost. However, existing counterweight tensioning devices still have certain limitations in practical use: during the process of the conveyor belt transitioning from no-load to load, the counterweight may swing or rise and fall significantly, resulting in large fluctuations in tension during operation, thus affecting the stability and service life of the conveyor belt.

[0004] Therefore, we propose an anti-slip device for conveyor belts to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an anti-slip device for conveyor belts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveyor belt anti-slip device, comprising a bearing seat, a spring, a telescopic component and a base plate, wherein a tensioning shaft is rotatably mounted on the bearing seat and is connected to the belt body in a transmission manner, and a weight block is provided on the lower surface of the bearing seat, and the tensioning shaft, the bearing seat and the weight block constitute a tensioning structure;

[0007] The base plate is provided with a telescopic component. The output end of the telescopic component is connected to the weight block through the spring. The telescopic component is used to limit the movement trajectory of the weight block, thereby reducing the fluctuation range of the tension of the belt body during operation.

[0008] Preferably, the telescopic assembly consists of a telescopic rod, a square groove, a square rod, a screw block, a lever, a cylindrical head, and a cylinder. The cylinder is rotatably mounted on the base plate, the screw block is threadedly engaged with the inner wall of the cylinder, and the telescopic rod is located on the upper surface of the screw block and penetrates the cylinder.

[0009] Preferably, the square grooves are respectively formed in the telescopic rod and the screw block, the cylindrical head is provided on the base plate and rotates in contact with the cylinder, the square rod is provided at the top of the cylindrical head and inserted into the square groove, and the paddles are equidistantly provided on the outer wall of the cylinder.

[0010] Preferably, each end of the spring is provided with a hanging plate, the top hanging plate of the spring is hung on the lower surface of the weight block, and the bottom hanging plate of the spring is hung on the telescopic rod of the telescopic assembly.

[0011] Preferably, the substrate has mounting holes, and the mounting holes are arranged in a ring array on the substrate.

[0012] Preferably, the lower surface of the bearing seat is provided with a connector, and the weight block is located at the bottom end of the connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, the conveyor belt anti-slip device of this utility model can be set at a designated position on the conveyor belt. The conveyor belt body is connected to the tensioning shaft. Under the action of the weight block, a downward force is applied to the shaft seat and the tensioning shaft, thereby tightening the conveyor belt body and preventing the belt from slipping.

[0015] When the conveyor belt is unloaded, the aforementioned tensioning structure tightens the belt, ensuring a stable height for the weight block. A spring is suspended from the lower surface of the weight block. The telescopic assembly then operates; a manual lever rotates the cylinder. Through the threaded engagement between the cylinder and the screw block, and with the screw block restrained by the square rod to prevent deflection, the cylinder's rotation is converted into the lifting and lowering of the telescopic rod. Once the telescopic rod reaches the designated height, the other end of the spring is attached to it. The spring and telescopic assembly work together to limit the position of the weight block, thus preventing large-scale lifting and lowering movements when the conveyor belt is under load. This suppresses tension fluctuations and improves the conveyor belt's load stability. Furthermore, the spring's deformable nature allows for slight movement of the weight block. When the conveyor belt loosens due to temperature changes or mechanical wear, the weight block automatically lowers to increase tension; conversely, it rises to reduce tension, maintaining constant tension through automatic compensation.

[0016] This invention employs a counterweight tensioning structure, combined with springs and telescopic components, to enable the weight block to automatically adjust according to the tension of the conveyor belt. This limits the position of the weight block, preventing large-scale lifting and lowering movements, reducing drastic fluctuations in tension, improving the load stability of the conveyor belt, and ensuring the continuity and reliability of material conveying.

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.

[0024] Example 1

[0025] like Figures 1-4 As shown, the present invention proposes an anti-slip device for a conveyor belt, comprising a bearing seat 3, a spring 5, a telescopic component 6, and a base plate 7. A tensioning shaft 2 is rotatably mounted on the bearing seat 3 and is connected to the belt body 1. A weight block 4 is provided on the lower surface of the bearing seat 3, and a connector 9 is provided on the lower surface of the bearing seat 3. The weight block 4 is located at the bottom end of the connector 9. The tensioning shaft 2, the bearing seat 3, and the weight block 4 constitute a tensioning structure. The conveyor belt body 1 is connected to the tensioning shaft 2. Under the gravity of the weight block 4, a downward force is applied to the bearing seat 3 and the tensioning shaft 2, thereby tightening the conveyor belt body 1 and preventing the belt from slipping.

[0026] The substrate 7 has mounting holes 8, which are arranged in a ring array on the substrate 7. The device is set at a designated position by cooperating with the ground anchor structure through the mounting holes 8.

[0027] The base plate 7 is provided with a telescopic component 6. The output end of the telescopic component 6 is connected to the weight block 4 through the spring 5. The telescopic component 6 is used to limit the movement trajectory of the weight block 4, thereby reducing the fluctuation range of the tension of the belt body 1 during operation.

[0028] Example 2

[0029] like Figures 1-4 As shown, the conveyor belt anti-slip device proposed in this utility model, compared with Embodiment 1, further includes: a telescopic assembly 6 composed of a telescopic rod 601, a square groove 602, a square rod 603, a screw block 604, a lever 605, a cylindrical head 606, and a cylinder 607. The cylinder 607 is rotatably mounted on the base plate 7. The screw block 604 is threadedly engaged with the inner wall of the cylinder 607. The telescopic rod 601 is located on the upper surface of the screw block 604 and penetrates the cylinder 607. The square groove 602 is respectively opened in the telescopic rod 601 and the screw block 604. The cylindrical head 606 is located on the base plate 7 and rotatably contacts the cylinder 607. The square rod 603 is located at the top of the cylindrical head 606 and inserted into the square groove 602. The levers 605 are equidistantly arranged on the outer wall of the cylinder 607. When the conveyor belt is unloaded, the above-mentioned tensioning structure is used to tension the conveyor belt. When tensioning is applied, the height of weight block 4 is stable. Spring 5 is suspended from the lower surface of weight block 4. Telescopic component 6 is activated. Personnel manually move lever 605 to rotate cylinder 607. Through the threaded engagement between cylinder 607 and screw block 604, and with screw block 604 constrained by square rod 603 to prevent deflection, the rotation of cylinder 607 is converted into the lifting and lowering of telescopic rod 601 under the principle of lead screw. After telescopic rod 601 reaches the specified height, the other end of spring 5 is hung on telescopic rod 601. Through the cooperation of spring 5 and telescopic component 6, the position of weight block 4 is constrained, thereby suppressing large-scale lifting and lowering of weight block 4 when the conveyor belt is under load, thus suppressing tension fluctuations and improving the load stability of the conveyor belt.

[0030] The spring 5 has hanging plates 10 at both ends. The top hanging plate 10 of the spring 5 is hung on the lower surface of the weight block 4, and the bottom hanging plate 10 of the spring 5 is hung on the telescopic rod 601 of the telescopic component 6. The design of the hanging plates 10 facilitates the connection between the spring 5, the weight block 4 and the telescopic component 6. At the same time, due to the deformable characteristics of the spring 5, the weight block 4 can move slightly. When the conveyor belt loosens due to factors such as temperature changes and mechanical wear, the weight block 4 automatically descends to increase the tension; conversely, the weight block 4 rises to reduce the tension, thus maintaining constant tension and automatically compensating.

[0031] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
