[0031] 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.
[0032] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a novel vibration reduction and noise reduction device for a coal mining machine electrical control system, comprising a housing 1 and a base 2. The housing 1 provides installation space and protection for internal components, while the base 2 provides support for the upper device and also provides installation space for internal components. The base 2 has sliding grooves 3 on both the left and right sides inside, which provide guidance and limiting for the slider 8. Multiple fixing posts 4 are fixedly connected to the bottom of the inner wall of the sliding groove 3, which provide space for the opening of the sliding groove 5. The sliding groove 5 is opened inside the fixing post 4, which provides guidance and limiting for the connecting post 6. The connecting post 6 is slidably connected inside the sliding groove 5, which connects the fixing post 4 and the slider 8.
[0033] A spring 7 is fitted around the outside of the connecting post 6. The spring 7 has an elastic function. A slider 8 is fixedly connected to the top of the connecting post 6. The housing 1 slides inside the base 2 through the slider 8 to reduce noise. Multiple elastic balls 9 are fixedly connected to the bottom of the inner wall of the base 2. The elastic balls 9 have an elastic function. A connecting plate 10 is fixedly connected to the top of the multiple elastic balls 9. The housing 1 slides down through the connecting plate 10 to squeeze the elastic balls 9 and buffers them through its own elasticity. A connecting block 11 is fixedly connected to the right side of the housing 1 to provide fixation and support for the connecting block 11. A reinforcing component for reinforcing the housing 1 is rotatably connected to the bottom right side of the connecting block 11.
[0034] Reference Figure 1 and Figure 3The reinforcing components include connecting post 2 12, which is subjected to external force and then transmitted to the rolling ball 13. The bottom of connecting post 2 12 is fixedly connected to the rolling ball 13, which can slide or roll inside the slide groove 3 16. The top of the rolling ball 13 is fixedly connected to the spring 2 14, which has an elastic function and provides elastic support for the elastic ball 9. Multiple connecting blocks 2 18 are fixedly connected to the right side of the base 2, which serve to fix and support the connecting blocks 2 18. The top of the connecting block 2 18 is rotatably connected to the connecting post 17, which serves to connect the connecting block 2 18 and the fixed post 2 15. The top of the connecting post 17 is fixedly connected to the fixed post 2 15, which provides space for the slide groove 3 16. The inner wall of the fixed post 2 15 has the slide groove 3 16, which provides guidance and limit for the rolling ball 13.
[0035] Reference Figures 1 to 3 Two sliders 8 are fixedly connected to the left and right sides of the housing 1 on their adjacent sides. When the housing 1 is subjected to external vibration, it slides through the sliders 8. The external side of the connecting post 1 6 is slidably connected to the inside of the slide groove 2 5, providing guidance and limiting for the connecting post 1 6. The top of the spring 1 7 is fixedly connected to the bottom of the slider 8, so that the spring 1 7 can directly receive the force from the slider 8. The bottom of the spring 1 7 is fixedly connected to the top of the fixed post 4, providing fixation and support for the spring 1 7. When the housing 1 is subjected to external vibration, the force is transmitted to the connecting post 1 6 through the sliders 8. When the housing 1 is subjected to external force and noise reduction and buffering are required, the sliders 8 on both sides slide to squeeze and transmit the force to the connecting post 1 6. The downward pressure of the connecting post 1 6 is buffered by the elastic action of the spring 1 7. At the same time as the connecting post 1 6 is pressed down, the slider 8 squeezes the spring 1 7, which is buffered by the elastic action of the spring 7. The connecting plate 10 squeezes the elastic ball 9, which absorbs most of the impact force through the elastic action of the elastic ball 9, thus buffering and reducing noise.
[0036] The top of the housing 1 is detachably connected to a top cover 19, which allows operators to easily open and inspect the internal components. Multiple connection ports 20 are provided on the exterior of the housing 1 for connection to the traction box. Transmission is achieved via cables through these ports. The rolling ball 13 is slidably connected to the interior of the slide groove 16, which provides guidance and positioning for the rolling ball 13. The top of the spring 14 is fixedly connected to the top of the inner wall of the slide groove 16, providing fixation and support. The connecting column 12 moves with the housing 1. Synchronous movement: When the housing 1 is subjected to external force and vibrates, the connecting column 2 12 can move synchronously with the movement of the housing 1. In turn, the rolling ball 13 rotates inside the sliding groove 3 16 to synchronize with the movement of the housing 1. This allows the rolling ball 13 to move synchronously inside the sliding groove 3 16 to adapt to the movement of the housing 1 and facilitate the reinforcement of the housing 1. In turn, the spring 2 14 reduces the wear on the rolling ball 13. When the rolling ball 13 rolls and slides, the spring 2 14 at its top provides cushioning, reducing the wear on the rolling ball 13 and extending its service life.
[0037] Working principle: When the coal mining machine vibrates during operation, the vibration causes the housing 1 to be subjected to force. The housing 1 then slides in the slide groove 3 via the sliders 8 on both sides. As the sliders 8 slide down, they cause the connecting column 6 to slide in the slide groove 5. At the same time, the sliders 8 compress the spring 7, using the elasticity of the spring 7 for buffering. Simultaneously, the sliders 8 push the connecting plate 10 to compress the elastic ball 9. The elasticity of the elastic ball 9 absorbs most of the impact force, achieving the effect of buffering and noise reduction, effectively reducing the impact of vibration on the internal components of the electrical control system.
[0038] When the housing 1 is vibrated and displaced, the housing 1 drives the connecting block 11, which in turn drives the connecting column 12 to move synchronously. The connecting column 12 drives the rolling ball 13 at the bottom to roll and slide in the groove 16 of the fixed column 15. The spring 14 then buffers the rolling ball 13, reducing wear. The movement of the rolling ball 13 can adapt to the movement of the housing 1, thus reinforcing the housing 1 and enhancing the overall stability of the device, enabling it to operate reliably in complex vibration environments.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
