Abstract
Description
Technical Field
[0001] This utility model belongs to the field of buffer platform technology, and in particular relates to a buffer platform for belt conveyor equipment. Background Technology
[0002] In industrial production, belt conveyors are widely used in numerous industries such as mining, metallurgy, building materials, and chemicals, undertaking the task of efficient material transportation. However, during the material conveying process, vibrations are unavoidable due to factors such as the impact of falling materials, the instability of belt operation, and the mechanical vibration of the equipment itself. These vibrations severely affect the normal operation and service life of belt conveyors.
[0003] Traditional belt conveyor systems often employ a single cushioning structure, such as a simple rubber pad or spring placed under the belt. This single cushioning structure may provide some buffering effect when the material flow is small and the vibration is relatively minor. However, when the material flow increases, such as in mining scenarios where large quantities of ore are rapidly transported via belt, the impact force upon descent is enormous, and the vibration is intense. In this situation, a single rubber pad or spring cannot effectively absorb the vibration energy, and the vibration is directly transmitted to various components of the belt conveyor. Prolonged exposure to this vibration environment can easily lead to belt wear and tear, shortening its lifespan and increasing replacement costs. Simultaneously, other critical components such as rollers and idlers may also experience bearing damage and loosening of connections due to vibration. Frequent equipment failures not only affect production efficiency but may also pose safety hazards.
[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content
[0005] To achieve the above objectives, this utility model proposes a buffer platform for belt conveyor equipment, comprising a base, a connecting plate fixedly installed on the side wall of the base, and a buffer mechanism fixedly installed on the top of the base. The buffer mechanism includes a first slide rail, which is fixedly installed on the top of the base. A sliding plate is slidably installed inside the first slide rail. A first piston rod is fixedly installed on the side wall of the sliding plate. A first slide cylinder is fixedly installed at the end of the first piston rod away from the sliding plate. A sliding block is fixedly installed on the side wall of the first slide cylinder. A first spring is fixedly installed inside the first slide cylinder. A first sliding rod is slidably installed inside the first slide cylinder. A first mounting seat is fixedly installed on the side wall of the first sliding rod. A connecting rod is rotatably installed inside the first mounting seat. A second mounting seat is rotatably installed at the end of the connecting rod away from the first mounting seat. A second sliding rod is fixedly installed on the side wall of the second mounting seat. A second slide cylinder is slidably installed on the side wall of the second sliding rod. A second spring is fixedly installed inside the second slide cylinder.
[0006] In one example, the sliding block is slidably mounted inside the first slide rail, and the first sliding rod is fixedly mounted to the first spring.
[0007] In one example, the second spring is fixedly installed with the second sliding rod, and the second slide cylinder is fixedly installed with the base.
[0008] In one example, a fixing plate is fixedly installed on the side wall of the sliding plate, and a threaded rod is fixedly installed on the side wall of the fixing plate.
[0009] In one example, a threaded cylinder is threadedly mounted on the side wall of the threaded rod, and a third slide is fixedly mounted on the top of the connecting plate.
[0010] In one example, a third sliding rod is slidably mounted inside the third slide cylinder, and a third spring is fixedly mounted inside the third slide cylinder.
[0011] In one example, the third spring is fixedly installed with the third sliding rod, and a receiving plate is fixedly installed on the top of the third sliding rod.
[0012] The buffer platform for belt conveyor equipment proposed in this utility model can bring the following beneficial effects:
[0013] First, the system employs a multi-stage buffering mechanism. This mechanism utilizes a receiving plate, a third sliding rod, a third sliding cylinder, and a third spring for initial buffering. Next, a second sliding rod, a second sliding cylinder, and a second spring further dissipate vibration energy. Finally, the first sliding rod, a first sliding cylinder, and a first spring absorb vibration energy again. This multi-stage buffering mechanism comprehensively and effectively reduces the impact of vibration on belt conveyors. Compared to a single buffering structure, it significantly improves buffering efficiency, better protects the various components of the belt conveyor, reduces equipment wear and malfunctions caused by vibration, and extends equipment lifespan. In environments with large material conveying volumes and severe vibrations, this buffering platform can significantly reduce the impact on the equipment and ensure stable operation.
[0014] Second, the buffer platform has an adjustable buffering force function. Simply rotating the threaded cylinder counterclockwise changes the position of the threaded rod through the threaded transmission, thereby changing the position of the fixed plate, sliding plate, and first piston rod, adjusting the initial position and stress state of the entire buffer structure. This allows the buffer platform to flexibly adapt to different levels of vibration. Whether it is slight or strong vibration, the optimal buffering effect can be achieved through adjustment. In practical applications, different production scenarios or the characteristics of the conveyed materials will lead to different vibration levels. The adjustability of this buffer platform greatly expands its application range, improves the versatility and practicality of the equipment, and reduces the cost incurred by enterprises due to the replacement of buffer equipment.

[0027] like Figures 1-4 As shown, the embodiment of this utility model proposes a buffer platform for belt conveyor equipment, which includes a base 11. If vibration occurs during use, the receiving plate 34 will receive the vibration. A connecting plate 12 is fixedly installed on the side wall of the base 11. The receiving plate 34 drives the third sliding rod 33 to move from top to bottom. A first slide rail 13 is fixedly installed on the top of the base 11. There is a large damping between the third sliding rod 33 and the third slide cylinder 31. The third sliding rod 33 moves from top to bottom, causing the third spring 32 to be compressed, which will reduce the vibration. A sliding plate 14 is slidably installed inside the first slide rail 13. The receiving plate 34 will also drive the second sliding rod 24 to move from top to bottom.
[0028] A first piston rod 15 is fixedly installed on the side wall of the sliding plate 14. A second sliding rod 24 slides inside the second sliding cylinder 26. There is also significant damping between the second sliding cylinders 26, and the second spring 25 will also be compressed. The end of the first piston rod 15 away from the sliding plate 14 is fixedly installed with the first sliding cylinder 16. The second sliding rod 24 drives the second mounting base 23 to move from top to bottom. A sliding block 17 is fixedly installed on the side wall of the first sliding cylinder 16. The second mounting base 23 drives the connecting rod 22 to flip. The sliding block 17 is slidably installed inside the first slide rail 13. The connecting rod 22 carries... The first mounting base 21 moves from the middle to both sides. The first spring 18 is fixedly installed inside the first slide cylinder 16. The first mounting base 21 will drive the first sliding rod 19 to move from the middle to both sides. The first sliding rod 19 is slidably installed inside the first slide cylinder 16. The first sliding rod 19 will slide inside the first slide cylinder 16. The first spring 18 will be compressed by force. At this time, the vibration will be further reduced. The first sliding rod 19 and the first spring 18 are fixedly installed. When it is necessary to adjust the buffer force, rotate the threaded cylinder 29 counterclockwise. The threaded rod 28 will retract into the threaded cylinder 29.
[0029] A first mounting base 21 is fixedly installed on the side wall of the first sliding rod 19. At this time, the fixing plate 27 will move from both sides towards the middle. A connecting rod 22 is rotatably installed inside the first mounting base 21. The fixing plate 27 will drive the sliding plate 14 to move from both sides towards the middle, and the first piston rod 15 will also retract, reducing the vibration force. A second mounting base 23 is rotatably installed at the end of the connecting rod 22 away from the first mounting base 21. A second sliding rod 24 is fixedly installed on the side wall of the second mounting base 23. A second sliding cylinder 26 is slidably installed on the side wall of the second sliding rod 24. A second spring is fixedly installed inside the second sliding cylinder 26. Spring 25, second spring 25 is fixedly installed with second sliding rod 24, second sliding cylinder 26 is fixedly installed with base 11, fixed plate 27 is fixedly installed on the side wall of sliding plate 14, threaded rod 28 is fixedly installed on the side wall of fixed plate 27, threaded cylinder 29 is threadedly installed on the side wall of threaded rod 28, third sliding cylinder 31 is fixedly installed on the top of connecting plate 12, third sliding rod 33 is slidably installed inside third sliding cylinder 31, third spring 32 is fixedly installed inside third sliding cylinder 31, third spring 32 is fixedly installed with third sliding rod 33, and receiving plate 34 is fixedly installed on the top of third sliding rod 33.
[0030] Working principle: When the belt conveyor vibrates, the receiving plate 34 installed on the top of the third sliding rod 33 first receives the vibration. The receiving plate 34 drives the third sliding rod 33 to move from top to bottom in the third sliding cylinder 31. Since there is a large damping between the third sliding rod 33 and the third sliding cylinder 31, and the movement of the third sliding rod 33 compresses the third spring 32, the vibration is initially reduced by using the damping and the elastic potential energy of the spring.
[0031] At the same time, the movement of the receiving plate 34 drives the second sliding rod 24 connected to it to move from top to bottom. The second sliding rod 24 slides inside the second sliding cylinder 26. The large damping between the second sliding cylinders 26 and the elastic deformation of the second spring 25 caused by compression further consume vibration energy.
[0032] The second sliding rod 24 drives the second mounting base 23 to move downward, causing the connecting rod 22, which is rotatably connected to the second mounting base 23, to flip. The flipping of the connecting rod 22 causes the first mounting base 21 to move from the middle to both sides. The first mounting base 21 then drives the first sliding rod 19 to slide from the middle to both sides inside the first sliding cylinder 16. The first spring 18 is compressed by force, and the vibration energy is further absorbed through the spring compression, so that the vibration is further reduced. Through this series of top-to-bottom, interconnected component movements, multi-stage vibration buffering effectively reduces the impact of vibration on the belt conveyor equipment.
[0033] When the buffering force needs to be adjusted, the threaded cylinder 29 is rotated counterclockwise. Utilizing the principle of thread transmission, the threaded rod 28 gradually retracts into the threaded cylinder 29. Since the threaded rod 28 is fixed on the fixed plate 27, the fixed plate 27 will move from both sides to the middle as the threaded rod 28 retracts. The fixed plate 27 is fixedly connected to the sliding plate 14, thereby driving the sliding plate 14 to move from both sides to the middle. The first piston rod 15 connected to the sliding plate 14 also retracts accordingly. This adjustment changes the initial position and force state of the entire buffer structure, thereby achieving the adjustment of the buffering force to adapt to different degrees of vibration.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

Various modifications and variations can be made to this utility model by those skilled in the art.
