Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. The figures are simplified schematic diagrams illustrating the basic structure of the invention in a schematic way only, and therefore they show only the components relevant to the invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to be referred must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be construed broadly, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, the two components can be communicated with each other inside, the fixed connection can be welding, gluing and the like, and for those skilled in the art, the specific meaning of the terms in the present invention can be understood according to specific situations.
The anti-seismic and noise-reducing supporting bottom plate of the diesel engine box body shown in the figure 1 comprises an inner plate body 3 and an outer plate body 1; the inner plate body 3 is fixedly connected with the outer plate body 1, and a layer of first sound-absorbing cotton 2 is filled between the inner plate body 3 and the outer plate body 1; the first cotton 2 of inhaling of sound of one deck is filled between interior plate body 3 and the planking body 1, and then diesel engine at the during operation, the noise that the inside part during operation of box produced and the whole noise that produces because of vibrations of diesel engine can be absorbed partly, and then reduce the propagation of noise in the air, play the effect of making an uproar.
The left inner wall and the right inner wall of the inner plate body 3 are uniformly and fixedly connected with two connecting plates 4, a layer of second sound-absorbing cotton 5 is filled in each connecting plate 4, at least two first anti-seismic springs 7 are uniformly arranged between the two connecting plates 4, and two ends of each first anti-seismic spring 7 are respectively and fixedly connected with the left inner wall and the right inner wall of the inner plate body 3; a plurality of second anti-vibration springs 6 are uniformly and fixedly connected between the connecting plate 4 and the inner wall of the upper side surface and the inner wall of the lower side surface of the inner plate body 3; the connecting plate 4 is arranged to enhance the strength of the bottom plate, and the second sound-absorbing cotton 5 is filled in the connecting plate 4, so that the sound-absorbing and noise-reducing effects can be further achieved; set up first antidetonation, the second is resisted and is shaken spring 6, and first antidetonation spring 7 and the second is resisted and is shaken spring 6 mutually perpendicular, and then can reduce the high frequency vibrations that diesel engine produced into low frequency vibrations, prevents that diesel engine from shaking under high frequency for a long time, influences the cooperation stability of each part, improves diesel engine's life, also can reduce the noise that high frequency vibrations brought simultaneously.
As shown in fig. 2, the four side surfaces of the outer plate body 1 are respectively provided with a gap, and the upper surface and the lower surface of the gap are uniformly and fixedly connected with a plurality of third anti-seismic springs 8; set up third antidetonation spring 8 in four sides of outer plate body 1, and then can effectively reduce diesel engine at the ascending vibration frequency of vertical side, and then can alleviate the noise that produces with the vibrations between the contact surface of other spare parts.
The thickness of the inner plate body 3 is greater than that of the outer plate body 1, and the thickness of the gap is less than that of the outer plate body 1; the thickness of the inner plate body 3 is the same as that of the outer plate body 1; because the first anti-seismic spring 7 and the second anti-seismic spring 6 are directly and fixedly connected with the inner wall of the inner plate body 3, when the diesel engine vibrates, the vibration after frequency reduction by the first anti-seismic spring 7 and the second anti-seismic spring 6 is directly transmitted to the inner plate body 3, so that the strength of the inner plate body 3 needs to be enhanced, and the thickness of the inner plate body 3 is larger than that of the outer plate body 1 so as to ensure the stability; the thickness of breach is less than the thickness of outer plate body 1, then the breach does not run through outer plate body 1, so has guaranteed the structural strength of outer plate body 1 equally.
