Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a damping diesel generator shown in a figure 1-2, which comprises a support frame 1, a generator body 2 arranged on the inner side of the support frame 1 and rubber cushion blocks 17 fixedly laid on the inner side of the support frame 1 and abutted against the periphery of the upper part of the generator body 2, wherein a plurality of bottom plates 7 are fixedly arranged at the bottom of the support frame 1, screw rods 4 are vertically welded on the bottom plates 7, the other ends of the screw rods 4 are fixedly connected with vertical rod ends of a U-shaped mounting frame 5 through nuts 6, and spring assemblies 3 are arranged between the horizontal rod parts of the U-shaped mounting frame 5 and the bottom plates 7;

the generator is characterized in that a piston cylinder 8 is fixedly mounted on a transverse rod part of the U-shaped mounting frame 5, a piston rod 9 corresponding to the piston cylinder 8 is welded at the lower end of the generator body 2, and a one-way valve joint 10 and a pressure release valve 11 are arranged at the lower part of the side surface of the piston cylinder 8.

When the diesel generator body 2 is assembled on the support frame 1, the generator body 2 is supported and placed in the support frame 1, the lower part of a piston rod 9 welded at the lower end of the generator body 2 is inserted into the piston cylinder 8, a rubber cushion block 17 fixedly paved at the inner side of the support frame 1 is pressed against the periphery of the upper part of the generator body 2, so that the upper part of the generator body 2 is relatively fixed, the lower part of the piston cylinder 8 is externally connected with an air pump through a one-way valve structure to suck the air in the piston cylinder 8, so as to generate the air pressure difference between the inside and the outside of the piston cylinder 8, the piston rod 9 is sucked, the upper end of the piston cylinder 8 is propped against the lower end of the generator body 2, after the pressure release valve 11 is manually rotated in the same way, air is sucked into the piston cylinder 8, the difference between the internal air pressure and the external air pressure disappears, the piston rod 9 can be easily pulled out of the piston cylinder 8, the installation is convenient, and the efficiency of the production and assembly of the generator is accelerated;

and a layered damping design is adopted, the upper layer is that a piston rod 9 and a piston cylinder 8 are matched to fix a generator body 2 through the internal and external air pressure difference of the piston cylinder 8, meanwhile, the negative pressure at the lower part of the inner side of the piston cylinder 8 buffers the slight shock of the generator by the pulling force of the piston rod 9, when the shock amplitude is larger, the shock is transmitted to a spring assembly 3 between the transverse rod part of a lower U-shaped mounting frame 5 and a bottom plate 7, after the shock is transmitted to the U-shaped mounting frame 5 through the piston rod 9 and the piston cylinder 8, the relative motion between the U-shaped mounting frame 5 and the bottom plate 7 is pushed, the spring assembly 3 is extruded, the large-amplitude shock when the generator body 2 is just started is quickly buffered through the restoring force of the spring assembly 3, after the working end time, the shock of the generator body 2 tends to be stable, when the shock amplitude is smaller, the shock absorption of, avoid when the less frequency of generator body 2 vibration amplitude is higher, the not sensitive enough of spring unit 3 buffering reaction causes the not enough condition of buffering effect, has strengthened the buffering effect.

Spring unit 3 comprises the first rubber seat 32 of compression spring 31 both ends joint that sets up and the middle part, and two first rubber seats 32 respectively with the horizontal pole portion and the 7 adhesions of bottom plate of U type mounting bracket 5. The convenience is assembled compression spring 31 between the horizontal pole portion and the bottom plate 7 of U type mounting bracket 5, simultaneously through the deformation effect that increases first rubber seat 32, increases spring unit 3's buffering response's sensitivity to the reinforcing is to the buffer effect of generator body 2 under less range vibrations.

The periphery of a piston rod 9 at the lower end of the generator body 2 is sleeved with a second rubber seat 12, and the upper end of a piston cylinder 8 is pressed on the end face of the second rubber seat 12. Avoid in the piston cylinder 8 too big negative pressure, lead to the piston cylinder 8 upper end to cause the extrusion damage to the lateral wall of generator body 2 lower extreme.

The U-shaped mounting frame 5 vertical rod part is U-shaped plate 13, and the lower extreme welding of U-shaped plate 13 has backup pad 14, through-hole 15 has been seted up on backup pad 14, through-hole 15 and nut 6 threaded connection are passed to the one end of screw rod 4, the inboard joint of through-hole 15 has rubber cushion collar 16. When making it upwards remove along screw rod 4 through swivel nut 6, under compression assembly's promotion, bottom plate 7 is kept away from to U type mounting bracket 5 subassembly, and reverse swivel nut 6 of the same reason makes it when along screw rod 4 downstream, drags U type mounting bracket 5 downstream, through supporting of spring assembly 3 and holding and nut 6 spacing for U type mounting bracket 5 keeps relatively stable, thereby the installation of the high adaptation generator assembly of adjustment piston cylinder 8, and the suitability is stronger.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
