[0015] The following combines the attached drawings to make a more detailed description of the above-mentioned and other technical features and advantages of the present utility model.

[0016] Combined with the attached Figures 1 to 4 As shown in the figure, a shock absorption device for a diesel generator set includes a lower sliding seat 1, a central sliding seat 1a is provided at the central position of the lower sliding seat 1; a slide cover 2, and the slide cover 2 is slidably installed on the lower sliding seat 1; a shock absorption assembly, and the shock absorption assembly is arranged inside the lower sliding seat 1 and the slide cover 2 for reducing vibration; it includes a leaf spring 3, the leaf spring 3 is in a cross shape, steel plate clamps 6 are provided on each section thereof, rollers 5 are provided at each end thereof, an intermediate bolt 4 is provided at the central position thereof, a first nut 4a and a second nut 4b are provided at the mating position of the intermediate bolt 4 and the leaf spring 3, and a third nut 4c is provided at the uppermost end of the intermediate bolt 4; a limit seat, the limit seat is arranged on the lower sliding seat 1, and there are 4 which are respectively matched with the corresponding rollers 5 for limiting the position of the rollers 5; each of the above limit seats includes two symmetrically arranged limit blocks;

[0017] It should be noted that during use, the shock absorption device is installed at the lower end of the base of the diesel generator set; during disassembly, only the third nut 4c needs to be removed, and the slide cover 2 can be directly removed.

[0018] First friction plates 5a are provided at both ends of the above rollers 5; each of the above limit blocks includes a slide sleeve 7, and the slide sleeve 7 is fixed on the lower sliding seat 1; a first slider 8, and the first slider 8 is slidably installed in the slide sleeve 7, and a second friction plate 8a that cooperates with the first friction plate 5a is provided at the outer end thereof; a compression spring 9, and there are several compression springs 9, all of which are arranged in the slide sleeve 7 for providing a pressing force to the first slider 8;

[0019] It should be noted that with use, both the first friction plate 5a and the second friction plate 8a are worn to varying degrees, so there will be a gap. At this time, under the action of the compression spring 9, the first slider 8 moves forward, driving the second friction plate 8a to continue to press against the first friction plate 5a, thereby eliminating the gap and enabling the second friction plate 8a to permanently abut against the first friction plate 5a.

[0020] Four V-shaped grooves 1b are provided on the above-mentioned lower sliding seat 1 and are symmetrically distributed around the center; each of the above-mentioned limiting blocks further includes a pressure adjusting mechanism for adjusting the pressure of the first slider 8 on the roller 5. The above-mentioned pressure adjusting mechanism includes a second slider 10. The second slider 10 is located at the bottom of the sliding sleeve 7 and is slidably matched with the sliding sleeve 7; one end of the pressing spring 9 abuts against the first slider 8, and the other end abuts against the second slider 10; a lead screw seat 11, the lead screw seat 11 is fixed on the lower sliding seat 1; a lead screw 12, the lead screw 12 is rotatably installed on the lead screw seat 11 and the lower sliding seat 1, and its mating end with the lower sliding seat 1 extends into the V-shaped groove 1b, and the extending end is provided with a bolt head 12a convenient for tool torsion; an adjusting slider 13, the adjusting slider 13 is arranged on the lead screw 12 and is slidably matched with the lower sliding seat 1, and its inner end is connected to the second slider 10;

[0021] It should be noted that when it is necessary to adjust the pressing force of the second friction plate 8a, a tool is used to drive the entire lead screw 12 to rotate by rotating the bolt head 12a. As the lead screw 12 rotates, the adjusting slider 13 moves forward, thereby driving the second slider 10 to move forward, and the pressing spring 9 is gradually compressed, thereby providing a greater pressing force to the second friction plate 8a.

[0022] A friction ring 2a slidably matched with the lower sliding seat 1 is provided on the inner side of the lower port of the above-mentioned sliding cover 2.

[0023] During use, the shock absorption device is subjected to the vibration pressure of the diesel generator set. The sliding cover 2 slides up and down relative to the lower sliding seat 1, and the friction ring 2a moves up and down relative to the lower sliding seat 1. Part of the vibration energy is consumed due to the friction between the friction ring 2a and the lower sliding seat 1; the leaf spring 3 undergoes elastic deformation under the influence of the vibration pressure, and part of the vibration energy is converted into the elastic potential energy of the leaf spring 3 and thus consumed; the leaf spring 3 disperses the vibration pressure to its lower end, thereby driving the lower roller 5 to reciprocate. As the roller 5 moves, the second friction plate 8a and the first friction plate 5a rub against each other, and part of the vibration energy is consumed due to the friction between the second friction plate 8a and the first friction plate 5a.

[0024] The present invention is not limited to the above-mentioned embodiments. Based on the technical solutions disclosed in the present invention, those skilled in the art can make some substitutions and deformations to some technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the present invention.
