Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation, and embodiment is as follows:
As shown in Fig. 1 ~ Fig. 6, the present invention's spliced L-type double-layer vibration isolating device, comprises left socle, right support, upper assembled plate 3, lower assembled plate 4 and plural rubber shock absorber;
Described left socle and right support are symmetrical structure, and it is by riser 15 and base plate composition; Described base plate is the double layer planar structure be made up of upper deck panels 17, side plate 18 and bottom panel 16, and upper deck panels 17 is vertical with bottom panel 16 to be connected in the two ends up and down of side plate 18 and to lay respectively at outside and the inner side of side plate 18; One end of upper deck panels 17, side plate 18 and bottom panel 16 all with the surface soldered of riser 15 lower half portion, form L-type structure;
Described assembled plate 3 and lower assembled plate 4 are the identical rectangular plate of structure, and it is processed with mounting hole on the surface; Side by side, its upper and lower two ends are fixedly connected with integral by upper assembled plate 3 with lower assembled plate 4 respectively for described left socle and right support; Described plural rubber shock absorber is arranged at the both sides of the top of bottom panel 16, the below of upper deck panels 17 and riser 15 respectively.
The present invention due to bottom panel 16 and upper deck panels 17 be the double-layer structure not in same level, by arranging rubber shock absorber on bottom panel 16 and upper deck panels 17, owing to there is height difference between the rubber shock absorber in two panels thus forming double-layer vibration isolating structure; Double-layer vibration isolating structure not only can the low-frequency vibration of suppression equipment, and can improve the vibration isolating effect to the whole frequency range of equipment, can make like this to reach good vibration isolating effect in limited space.
Due to the restriction by boats and ships bulk, if by structure in aggregates for support Design, then when being carried in cabin, may be more difficult; Therefore the present invention to be preferably connected side by side by two symmetrical L-type structural members for the support that carries required device for vibration insutation and to be formed.
Support concrete assembly process in left and right is as follows:
First two symmetrical L-type structural members 1 and L-type structural member 2 are stitched together by the present invention side by side, and by assembled plate 3 and the assembled plate 4 hexagon head articulation bolt of M16 × 60, L-type structural member 1 and L-type structural member 2 are positioned (ensure that double-layer vibration isolating device enters the conformity of structure before and after cabin, and then can ensure that the planeness of each mounting plane of vibration damper and perpendicularity require).Then by the hexagon head bolt of M16 × 70, the splicing panel 5 of L-type structural member 1 and L-type structural member 2 is linked together.Wherein, L-type structural member is welded by riser 15, bottom panel 16, upper deck panels 17 and side plate 18.Two vibration damper installation panels have respectively been welded in riser 15 liang of rear flank, and bottom panel 16 upper surface has welded two vibration damper installation panels, and upper deck panels 17 lower surface has welded three vibration damper installation panels.After assembling, support in the soleplate portion forms a pit, and the equipment of required damping is connected with the rubber shock absorber in this pit plane by bolt.
In order to increase the structural strength of base plate, the present invention is provided with multiple bracket between upper deck panels and side plate.
Left and right of the present invention support and assembled plate all adopt steel to process, and for ensureing double-layer vibration isolating apparatus structure intensity, require to carry out ultrasonic flaw detection process to the weld seam of left and right support key position, and its evaluation result meet II grade of requirement.Shot blasting on surface process is carried out to left and right support and assembled plate simultaneously, and in its surface spraying solvent-free epoxy antirust paint, and ensure primer dry films thickness >=200um, finish paint thickness >=100um.Strengthen the anticorrosion and anti ageing property of left and right support and assembled plate
In order to reduce the weight of support, the present invention arranges multiple lightening hole respectively on riser and base plate.
The present invention is in actual applications due to restriction spatially, and described riser is two sections respectively, and two sections stagger in the horizontal direction mutually.
As shown in Fig. 3 ~ Fig. 7, the installation process of multiple rubber shock absorber is as follows:
The present invention includes 18 rubber shock absorbers, wherein have 6 for SJA-500 vibration damper, 8 is BE-400 vibration damper, and 4 is SJA-500 vibration damper; First 6 SJA-500 vibration dampers 9 are connected with the installation panel 13 on deck panels 17 bottom surface on the support of left and right by bolt, secondly 4 BE-400 vibration dampers 7 are connected with the installation panel 11 on outside left and right support riser 15 by bolt, again connected with the installation panel 12 in left and right bracket bottom deck panels 16 by bolt by 4 SJA-500 vibration dampers 8, then 4 BE-400 vibration dampers 6 are connected with the riser 15 inboard mounting surface plate 10 of left and right support by bolt.
As shown in Figure 6, the base plate of double-layer vibration isolating device of the present invention adopts concave structure form, SJA-500 vibration damper 9 and pedestal 14 stagger in the height direction with SJA-500 vibration damper 8, double-layer vibration isolating device can be reduced at its height perpendicular to mounting plane, for environment space narrow and small on ship, interfere with equipment top hull structure (on bed board and ship other system pipeline etc.) after equipment can be avoided to install double-layer vibration isolating device additional, reduce equipment to greatest extent because of what install that double-layer vibration isolating device brings additional and involve engineering.Structural member 1 and 2 is connected by hexagon head bolt by double-layer vibration isolating device, can provide convenience for the cabin stage of entering of double-layer vibration isolating device aboard ship in installation process, reduces into involving engineering in the process of cabin.Meanwhile, adopt assembled plate to position double-layer vibration isolating device, the conformity of the assembled front and back of double-layer vibration isolating device can be ensured.
By carrying out landly joining machine test, Spot detection after testing to drainage pump in test room, result shows: drainage pump is under declared working condition: under-chassis vibration acceleration on average shakes level decline 35dB, and double-layer vibration isolating device vibration isolating effect is remarkable.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
