Description

Technical Field

[0001] This utility model relates to the technical field of belt protection devices, and in particular to a protective device for guide belts. Background Technology

[0002] Traditional belt conveyors are widely used in industrial production, mainly for the continuous transport of materials. Their basic structure includes a belt, a belt conveyor frame, and a power unit that drives the belt. As a key component for carrying and transporting materials, the belt needs to operate continuously during the transport process. The belt conveyor frame provides support and a running track for the belt, ensuring that the belt runs along a predetermined path. This traditional device plays an important role in material transport scenarios in many industries, such as mines, ports, and building materials, undertaking a large number of material transport tasks. When belt protection devices are in use, a significant technical defect of traditional belt conveyors is the friction between the belt and the belt support base. During long-term operation, due to the direct contact between the belt and the belt support base and the relative movement between them, continuous friction leads to wear on the belt surface. As the wear intensifies, the belt thickness gradually decreases, its strength reduces, and it is highly prone to breakage. This not only increases the workload of belt maintenance, as a new belt needs to be replaced promptly after a breakage, but also may cause electromechanical transportation accidents during equipment operation, posing a serious threat to production safety.

[0003] Therefore, to address the issue of the difficulty in reducing the risk of belt wear and breakage during continuous operation, a protective device for guide belts can be designed. When in use, this protective device, through the synergistic action of protective idlers, buffer damping blocks, buffer springs, and connecting mechanisms, effectively buffers the vibrations generated during belt operation, ensuring that the protective idlers remain in close contact with the bottom surface of the belt. This prevents the belt from wearing against the belt frame during operation, significantly extending the belt's service life and reducing the risk of breakage due to prolonged wear. Furthermore, the sliding wheels located at both ends of the protective idlers effectively reduce wear on the sides of the belt, further protecting it and thus ensuring the stable operation of the belt conveyor. Utility Model Content

[0004] To overcome the problem that traditional belt conveyors are prone to friction with the belt and the belt support base during use, continuous friction leads to wear on the belt surface. As the wear intensifies, the belt thickness gradually decreases and its strength is reduced. Therefore, it is difficult to reduce the risk of belt wear and breakage when used in continuous operation scenarios.

[0005] The technical solution of this utility model is as follows: a protective device for a guide belt, including a mounting base, a protective roller rotatably mounted inside the mounting base, a rotating shaft passing through and fixedly mounted inside the protective roller, the two ends of the rotating shaft passing through through slots on both sides of the mounting base, and multiple sets of frames. Two sets of frames are symmetrically fixedly mounted on the outer walls of both sides of the mounting base. A support column is fixedly mounted inside each set of frames. A buffer damping block is slidably sleeved on the side wall of each set of support columns. A connecting mechanism is rotatably sleeved on both ends of the rotating shaft. The two sides of the connecting mechanism are fixedly connected to the inner walls of the buffer damping blocks on both sides. A buffer spring is fixedly mounted between the bottom wall of each set of buffer damping blocks and the inner bottom wall of the frame. Multiple sets of sliding wheels are symmetrically rotatably mounted on both ends of the protective roller.

[0006] Preferably, when the belt protection device is in use, the two ends of the mounting base are first securely fixed inside the belt conveyor frame. At this time, the bottom surface of the belt will be tightly pressed against the surface of the protective idler. During the operation of the belt, the friction between the belt and the surface of the protective idler will drive the protective idler to rotate. When vibration occurs during the operation of the belt, the vibration will be transmitted to the protective idler. Each set of buffer damping blocks will move up and down along the support column, generating sliding friction during this process, consuming some vibration energy. At the same time, under the action of vibration, the buffer spring will be compressed or stretched, further absorbing and buffering the vibration through its elastic deformation, so that the protective idler can still be tightly pressed against the bottom surface of the belt under the influence of vibration, ensuring the tightness between the belt and the protective idler. With good contact and stable operation, when the side of the belt contacts the sliding wheel, the rotation of the sliding wheel reduces the friction on the side of the belt, thus reducing wear. In summary, this guide belt protection device, through the synergistic action of the protective idler, buffer damping block, buffer spring, and connecting mechanism, can effectively buffer the vibration generated during belt operation, ensuring that the protective idler is always in close contact with the bottom surface of the belt. This prevents the belt from wearing against the belt frame during operation, greatly extending the belt's service life and reducing the risk of breakage due to prolonged wear. Furthermore, the sliding wheels located at both ends of the protective idler effectively reduce wear on the side of the belt, further protecting the belt and thus ensuring the stable operation of the belt conveyor.

[0007] Preferably, the upper end of the buffer spring is fixedly connected to the bottom wall of the buffer damping block, and the lower end of the buffer spring is fixedly connected to the inner bottom wall of the frame. The mounting base has a U-shaped structure, and multiple sets of sliding wheels are distributed in a circumferential array.

[0008] Preferably, the connecting mechanism includes a connector and a rotating bushing. The connector is fixedly arranged between the two sets of buffer damping blocks, and the rotating bushings are rotatably sleeved on both ends of the rotating shaft. Each set of rotating bushings is rotatably arranged inside the connector.

[0009] Preferably, a rubber pad is fixedly installed on the inner top wall of each frame group, and the rubber pad is located above the buffer damping block.

[0010] Preferably, fixed bases are symmetrically fixed on the outer walls of both sides of the mounting base, and two sets of support seats are fixedly installed on the top of the fixed bases. The top of each set of support seats is fixedly connected to the bottom of the frame, and a triangular support frame is fixedly installed on the side wall of each set of support seats.

[0011] Preferably, the protective roller is symmetrically fixed with fixing rings at both ends. Each fixing ring has multiple sets of mounting grooves running through it. Multiple sets of sliding wheels correspond one-to-one with the multiple sets of mounting grooves, and the sliding wheels are rotatably mounted inside the mounting grooves.

[0012] The beneficial effects of this utility model are: 1. When using this belt protection device, first securely fix both ends of the mounting base inside the belt conveyor frame. At this time, the bottom surface of the belt will be tightly pressed against the surface of the protective idler. During the operation of the belt, the friction between the belt and the surface of the protective idler will drive the protective idler to rotate. When vibration occurs during the belt operation, the vibration will be transmitted to the protective idler. Each set of buffer damping blocks will move up and down along the support column, generating sliding friction during this process, consuming some vibration energy. At the same time, under the action of vibration, the buffer spring will be compressed or stretched, further absorbing and buffering the vibration through its elastic deformation, so that the protective idler can still be tightly pressed against the bottom surface of the belt under the influence of vibration, ensuring good contact between the belt and the protective idler. Good contact and stable operation: When the side of the belt contacts the sliding wheel, the rotation of the sliding wheel reduces the friction on the side of the belt, thus reducing wear. In summary, this guide belt protection device, through the synergistic action of the protective idler, buffer damping block, buffer spring, and connecting mechanism, can effectively buffer the vibration generated during belt operation, ensuring that the protective idler is always in close contact with the bottom surface of the belt. This prevents the belt from wearing against the belt frame during operation, greatly extending the belt's service life and reducing the risk of breakage due to prolonged wear. Furthermore, the sliding wheels located at both ends of the protective idler effectively reduce wear on the side of the belt, further protecting the belt and thus ensuring the stable operation of the belt conveyor.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides an embodiment of a protective device for a guide belt, including a mounting base 1, a protective roller 2 rotatably mounted inside the mounting base 1, a rotating shaft 3 passing through and fixedly mounted inside the protective roller 2, the two ends of the rotating shaft 3 passing through through slots on both sides of the mounting base 1, and multiple sets of frames 4. Two sets of frames 4 are symmetrically fixedly mounted on the outer walls of both sides of the mounting base 1. A support column 5 is fixedly mounted inside each set of frames 4. A buffer damping block 6 is slidably sleeved on the side wall of each set of support columns 5. A connecting mechanism is rotatably sleeved on both ends of the rotating shaft 3. The two sides of the connecting mechanism are fixedly connected to the inner walls of the buffer damping blocks 6 on both sides. A buffer spring 7 is fixedly mounted between the bottom wall of each set of buffer damping blocks 6 and the inner bottom wall of the frame 4. Multiple sets of sliding wheels 16 are symmetrically rotatably mounted on both ends of the protective roller 2.

[0017] Please see Figure 3 and Figure 4The upper end of the buffer spring 7 is fixedly connected to the bottom wall of the buffer damping block 6, and the lower end of the buffer spring 7 is fixedly connected to the inner bottom wall of the frame 4. The mounting base 1 has a U-shaped structure, and multiple sets of sliding wheels 16 are arranged in a circumferential array. Under the action of vibration, the buffer spring 7 will be compressed or stretched, and the vibration will be further absorbed and buffered through its elastic deformation. The connecting mechanism includes a connector 8 and a rotating bushing 9. The connector 8 is fixedly set between the two sets of buffer damping blocks 6. The rotating bushing 9 is rotatably sleeved on both ends of the rotating shaft 3. Each set of rotating bushing 9 is rotatably set inside the connector 8. While the rotating shaft 3 drives the protective roller 2 to rotate, its two ends can be flexibly rotated in the connector 8 through the rotating bushing 9. A rubber pad 10 is fixedly set on the inner top wall of each set of frames 4. The rubber pad 10 is located above the buffer damping block 6. The rubber pad 10 can prevent the buffer damping block 6 from colliding with the inner top wall of the frame 4.

[0018] Please see Figure 2 and Figure 5 The mounting base 1 has fixed bases 11 symmetrically fixed on both outer walls. Two sets of support seats 12 are fixedly installed on the top of the fixed bases 11. The top of each set of support seats 12 is fixedly connected to the bottom of the frame 4. Triangular support frames 13 are fixedly installed on the side walls of each set of support seats 12. These structures together enhance the load-bearing capacity of the frame 4 and ensure that the entire device remains stable when subjected to various forces generated by the belt running. Fixed rings 14 are symmetrically fixed on both ends of the protective roller 2. Multiple sets of mounting grooves 15 are opened through the inside of each set of fixed rings 14. Multiple sets of sliding wheels 16 correspond one-to-one with multiple sets of mounting grooves 15. The sliding wheels 16 are rotatably installed inside the mounting grooves 15. When the side of the belt contacts the sliding wheel 16, the rotation of the sliding wheel 16 can reduce the friction force on the side of the belt and reduce the wear on the side of the belt.

[0019] When the belt protection device is in use, the two ends of the mounting base 1 are first firmly fixed inside the belt conveyor frame. At this time, the bottom surface of the belt will be tightly attached to the surface of the protective idler 2. When the belt is running, the friction between the belt and the surface of the protective idler 2 will drive the protective idler 2 to rotate. The rotating shaft 3 that is fixed inside the protective idler 2 will also rotate. The two ends of the rotating shaft 3 pass through the through slots on both sides of the mounting base 1, and the two ends of the rotating shaft 3 are respectively rotatably sleeved with rotating bushings 9. These rotating bushings 9 are rotatably set inside the connecting piece 8. The connecting piece 8 is fixedly connected between the buffer damping blocks 6 on both sides. In this way, while the rotating shaft 3 drives the protective idler 2 to rotate, its two ends can be flexibly rotated in the connecting piece 8 through the rotating bushings 9.

[0020] When vibration occurs during belt operation, the vibration is transmitted to the protective idler roller 2. Since each set of frames 4 has a fixed support column 5 inside, and the side wall of the support column 5 is slidably fitted with a buffer damping block 6, and the two ends of the rotating shaft 3 are fixedly connected to the inner wall of the buffer damping block 6 through a connecting mechanism, each set of buffer damping blocks 6 will move up and down along the support column 5. During this process, sliding friction is generated, which consumes some vibration energy. At the same time, a buffer spring 7 is fixedly installed between the bottom wall of each set of buffer damping blocks 6 and the inner bottom wall of the frame 4. Under the action of vibration, the buffer spring 7 will be compressed or stretched, and its elastic deformation will further absorb and buffer the vibration, so that the protective idler roller 2 can still be tightly attached to the bottom surface of the belt under the influence of vibration, ensuring good contact and stable operation between the belt and the protective idler roller 2.

[0021] In addition, fixed bases 11 are symmetrically fixed on the outer walls of both sides of the mounting base 1, and support bases 12 are installed on the top of the fixed bases 11. The top of the support base 12 is fixedly connected to the bottom of the frame 4, and the side wall of the support base 12 is provided with a triangular support frame 13. These structures together enhance the load-bearing capacity of the frame 4, ensuring that the entire device remains stable when subjected to various forces generated by the belt running. Fixed rings 14 are symmetrically fixed on both ends of the protective roller 2. Multiple sets of mounting grooves 15 are opened inside the fixed rings 14, and multiple sets of sliding wheels 16 are rotatably arranged in the mounting grooves 15. When the side of the belt contacts the sliding wheel 16, the rotation of the sliding wheel 16 can reduce the friction force on the side of the belt and reduce the wear on the side of the belt.

[0022] This protective device for the guide belt has several significant benefits: First, through the coordinated action of the protective idler roller 2, the buffer damping block 6, the buffer spring 7, and the connecting mechanism, it can effectively buffer the vibration generated during belt operation, ensuring that the protective idler roller 2 is always in close contact with the bottom surface of the belt. This prevents the belt from wearing against the belt frame during operation, greatly extending the belt's service life and reducing the risk of breakage due to prolonged wear, thus ensuring the stable operation of the belt conveyor. Second, the installation of the fixed base 11, support seat 12, and triangular support frame 13 enhances the load-bearing capacity of the frame 4, improving the structural stability of the entire device and enabling it to better adapt to different working environments and load requirements. Finally, the sliding wheels 16 installed at both ends of the protective idler roller 2 effectively reduce wear on the sides of the belt, further protecting it. Moreover, the device has a reasonable structure and is easy to install, greatly improving work efficiency during production and maintenance, saving time and costs for enterprises.

[0023] Through the above steps, when the belt protection device is in use, firstly, the two ends of the mounting base 1 are firmly fixed inside the belt conveyor frame. At this time, the bottom surface of the belt will be tightly attached to the surface of the protective idler roller 2. When the belt is running, the friction between the belt and the surface of the protective idler roller 2 will drive the protective idler roller 2 to rotate. When vibration occurs during the belt operation, the vibration will be transmitted to the protective idler roller 2. Each set of buffer damping blocks 6 will move up and down along the support column 5. During this process, sliding friction is generated, which consumes some vibration energy. At the same time, under the action of vibration, the buffer spring 7 will be compressed or stretched, and its elastic deformation will further absorb and buffer the vibration, so that the protective idler roller 2 can still be tightly attached to the bottom surface of the belt under the influence of vibration, ensuring the tightness between the belt and the protective idler roller 2. With good contact and stable operation, when the side of the belt contacts the sliding wheel 16, the rotation of the sliding wheel 16 can reduce the friction force on the side of the belt and reduce the wear on the side of the belt. In summary, this guide belt protection device, through the synergistic action of the protective idler 2, the buffer damping block 6, the buffer spring 7 and the connecting mechanism, can effectively buffer the vibration generated during the operation of the belt, so that the protective idler 2 is always in close contact with the bottom surface of the belt, avoiding wear between the belt and the belt frame during operation, greatly extending the service life of the belt, and reducing the risk of belt breakage due to long-term wear. Secondly, the sliding wheels 16 set at both ends of the protective idler 2 effectively reduce the wear on the side of the belt, further protecting the belt, thus ensuring the stable operation of the belt conveyor.
