DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figs. 1-3The utility model provides a technical scheme: a device for reducing the vibration of a vertical mill speed reducer,

[0023] The fixed track base 1 is a basic supporting component of the whole device, provides a stable mounting base for subsequent components, determines the layout position of the whole device, bears the weight and force from the components and equipment above during operation, and is integrally provided with a position sliding seat 2 at the end of the fixed track base 1 for moving the equipment at the end of the fixed track base 1. The position sliding seat 2 is located at the end of the fixed track base 1, supports the fixed track base 1 on one side and provides a directional sliding platform for the equipment moving seat 3 on the other side, so that the equipment moving seat 3 can move along a predetermined track. The bar-shaped stabilizing seat 9 at the bottom of the equipment moving seat 3 strengthens the overall stability. The vibration stopping top groove 10 on both sides provides accurate positioning for subsequent vibration stopping components and assists in suppressing vibration.

[0024] The equipment moving seat 3 for installing and fixing the equipment is directionally slid on the position sliding seat 2. The equipment moving seat 3 is used for installing and fixing the vertical mill speed reducer main body 5 and is a key component for connecting the speed reducer and the whole moving and vibration stopping system. The speed reducer can move directionally along the position sliding seat 2, and the position adjustment is realized by cooperating with the directional moving block 8 below. The pneumatic vibration stopping plate 4 on both sides of the equipment moving seat 3 is used for tightly stopping vibration and is provided with an L-shaped structure and extends to the bottom end of the position sliding seat 2 on both sides. The pneumatic vibration stopping plate 4 has an L-shaped structure and extends to the bottom end of the position sliding seat 2. By means of the vibration stopping tightening cylinder 11 and the vibration stopping top plate 12, the vibration stopping top plate 12 is tightly stopped in the vibration stopping top groove 10 under the pushing of the cylinder. By generating a reverse force, the tightly stopping force is applied to the equipment moving seat 3 on both sides, effectively buffering and offsetting the vibration generated during operation.

[0025] The vertical mill speed reducer main body 5 undertakes the key power transmission and speed reduction task in the grinding production process. Stable operation has a significant impact on production efficiency and quality. By being connected with the equipment moving seat 3 and by means of a series of vibration stopping components, low-vibration operation is ensured. The vertical mill speed reducer main body 5 is fixed at the end of the equipment moving seat 3, and the pneumatic vibration stopping telescopic rod 6 is arranged at the bottom of the equipment moving seat 3 on both sides for tightly stopping and stabilizing the vertical mill speed reducer main body 5. The pneumatic vibration stopping telescopic rod 6 is installed at the bottom of the equipment moving seat 3, slides in the bar-shaped groove 17 and tightly stops the vertical mill speed reducer main body 5 upward. By means of the telescopic action, vertical support and buffering force is provided to supplement the shock absorption protection at the bottom of the vertical mill speed reducer and cooperate with the pneumatic vibration stopping plate 4 to reduce the influence of vibration on the speed reducer from multiple directions.

[0026] The bottom of the equipment moving seat 3 is provided with a directional moving block 8 for position movement on the position sliding seat 2 through a lead screw 7, which is arranged in a directional track groove 13 at the end of the equipment moving seat 3 and threadedly cooperates with the directional moving block 8. When the lead screw 7 rotates under the drive of a servo motor 14, the directional moving block 8 is accurately moved along the directional track groove 13 by the screw transmission principle, so as to realize the position adjustment of the equipment moving seat 3 and the vertical mill reducer. The directional moving block 8 is at the bottom of the equipment moving seat 3 and cooperates with the lead screw 7 to realize the position adjustment action. The strip-shaped guide blocks 15 at the bottom of the equipment moving seat 3 cooperate with the guide grooves 16 to provide accurate guidance for the movement of the equipment moving seat 3, so as to ensure the stability and smoothness of the movement and avoid additional vibration caused by position adjustment.

[0027] The bottom of the position sliding seat 2 is provided with a strip-shaped stabilizing seat 9 fixed at the end of the fixed track seat 1, which provides more stable bottom support for the position sliding seat 2, uniformly disperses the weight of the equipment, enhances the rigidity of the overall structure, reduces the shaking and vibration caused by uneven local stress, and provides a strip-shaped vibration stopping top groove 10 at the bottom of the position sliding seat 2, which is located at the bottom of the position sliding seat 2 and provides a tight top position for the vibration stopping top plate 12 of the pneumatic vibration stopping plate 4, limits the action point of the vibration stopping component, ensures the accurate and efficient transmission of the vibration stopping force, and improves the vibration stopping effect.

[0028] The bottom end of the pneumatic vibration stopping plate 4 extends to the lower end surface of the position sliding seat 2, and the extension part of the pneumatic vibration stopping plate 4 is provided with a vibration stopping and tightening cylinder 11 at the upper end, which is installed at the upper end of the extension part of the pneumatic vibration stopping plate 4 and provides power for the vibration stopping top plate 12. The vibration stopping and tightening cylinder 11 can flexibly adjust the top tightening force of the top plate according to the vibration situation, adapt to different vibration amplitudes, ensure stable vibration stopping effect, and the vibration stopping and tightening cylinder 11 is provided with a vibration stopping top plate 12 with anti-slip tooth pattern and tightly top in the vibration stopping top groove 10. The vibration stopping top plate 12 with anti-slip tooth pattern is tightly top in the vibration stopping top groove 10. The anti-slip tooth pattern increases the friction force, prevents loosening, ensures that the vibration stopping force can still be stably transmitted under vibration impact, and maintains the stability of the equipment.

[0029] When the vibration occurs in the vertical mill reducer body 5 during operation, the vibration energy will try to displace the reducer. At this time, the pneumatic vibration stopping telescopic rod 6 will respond quickly by virtue of its pneumatic characteristics. Since it is filled with gas inside, the compressibility of the gas enables it to buffer the instantaneous impact and absorb part of the vibration energy, preventing the vibration from being directly transmitted to the equipment moving base 3. With the change of vibration amplitude, the pneumatic system can automatically adjust the gas pressure inside the telescopic rod. If the vibration intensifies, the gas inside the telescopic rod is further compressed, and its reaction force also increases accordingly, more effectively pushing the reducer upward and offsetting the increased vibration. Conversely, when the vibration weakens, the gas pressure is adjusted accordingly, maintaining a stable support and buffering state, continuously damping the reducer. The pneumatic vibration stopping telescopic rod 6 cooperates with other vibration stopping components in the device, such as the pneumatic vibration stopping plates 4 on both sides. The pneumatic vibration stopping plates 4 tighten the equipment moving base 3 from the horizontal direction, while the pneumatic vibration stopping telescopic rod 6 focuses on the vertical direction, reducing vibration from multiple directions, ensuring that the vertical mill reducer body 5 is always in a stable running environment with low vibration.

[0030] The equipment moving base 3 is provided with a directional track groove 13 for moving the directional moving block 8. The directional track groove 13 is arranged at the end of the equipment moving base 3 to provide a track for the directional moving block 8 to move directionally, constrain the moving direction, and ensure that the equipment moving base 3 and the vertical mill reducer move along the preset route when adjusting the position. The lead screw 7 is arranged in the directional track groove 13 and threadedly penetrates the directional moving block 8. One end of the lead screw 7 is drivingly connected to the servo motor 14 arranged outside the strip-shaped stabilizing seat 9. The servo motor 14 is installed outside the strip-shaped stabilizing seat 9 and drivingly connected to the lead screw 7 to provide accurate power for the rotation of the lead screw 7 and drive the lead screw 7 to rotate according to the control command, thereby achieving high-precision adjustment of the position of the equipment moving base 3.

[0031] The strip-shaped guide block 15 is arranged at the bottom end of the directional moving block 8 and embedded in the corresponding guide groove 16 to guide the directional moving block 8 to move stably during movement. The strip-shaped guide block 15 is provided with a guide groove 16 at a position corresponding to the directional track groove 13, and the guide groove 16 is arranged corresponding to the strip-shaped guide block 15 to provide a containing and guiding space for the strip-shaped guide block 15, assist the directional moving block 8 to move accurately, and maintain the stability of the entire device during movement.

[0032] The upper end surface of the position sliding seat 2 and located on both sides of the directional track groove 13 is provided with a strip-shaped groove 17 for tightly abutting the pneumatic vibration-stopping telescopic rod 6 inside and upward, the strip-shaped groove 17 is located on the upper end surface of the position sliding seat 2 and on both sides of the directional track groove 13, which provides a sliding and tightly abutting space for the pneumatic vibration-stopping telescopic rod 6, regulates the action path, guarantees the stability and effectiveness of the upward tightly abutting of the vertical mill reducer main body 5, and the equipment moving seat 3 is provided with a vibration sensor 18 on one side of the end portion, which monitors the vibration condition in real time during the equipment operation, feeds back the vibration data, facilitates the operator to judge the equipment state, or provides a basis for the automatic control system, and timely adjusts the vibration-stopping strategy.

[0033] Specifically, in use, the vertical mill reducer main body 5 is installed at the end portion of the equipment moving seat 3, the equipment moving seat 3 is on the position sliding seat 2 and can slide in a direction, and the position sliding seat 2 is located at the end portion of the fixed track seat 1. Among them, the strip-shaped stable seat 9 at the bottom of the position sliding seat 2 is fixed at the end portion of the fixed track seat 1, which plays a role in stable support and avoids shaking, the vibration-stopping top groove 10 at both sides of the bottom of the position sliding seat 2 provides positioning for the subsequent vibration-stopping components, the bottom end of the L-shaped pneumatic vibration-stopping plate 4 on both sides extends to both sides of the lower end surface of the position sliding seat 2, the vibration-stopping tightly abutting air cylinder 11 at the upper end drives the vibration-stopping top plate 12 with anti-skid tooth pattern to tightly abut in the vibration-stopping top groove 10, and the equipment moving seat 3 is tightly abutted from both sides, so as to reduce vibration. At the same time, the pneumatic vibration-stopping telescopic rod 6 at both sides of the bottom of the equipment moving seat 3 slides in the strip-shaped groove 17 and tightly abuts the vertical mill reducer main body 5 upward, so as to suppress vibration in multiple directions.

[0034] When the position of the vertical mill reducer needs to be adjusted, the servo motor 14 outside the strip-shaped stable seat 9 drives the screw rod 7 to rotate, since the screw rod 7 is threaded through the directional moving block 8 and the directional moving block 8 is located in the directional track groove 13 at the end portion of the equipment moving seat 3, the directional moving block 8 will move accurately along the directional track groove 13 under the rotation of the screw rod 7, the strip-shaped guide block 15 at both sides of the bottom end slides along the guide groove 16, so as to guarantee stable and accurate movement, make the equipment move as required, and the vibration sensor 18 on one side of the end portion of the equipment moving seat 3 monitors the vibration condition in real time, once abnormal vibration is captured, data can be provided for the operator to troubleshoot in time, or as a basis for the automatic control system, so as to adjust the vibration-stopping related components, maintain stable and low-vibration operation of the equipment.
