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 spliced L-type double-layer vibration isolating of the present invention 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 forms by riser 15 and base plate; Described base plate is the double layer planar structure consisting of upper deck panels 17, side plate 18 and bottom panel 16, upper deck panels 17 outside and the inner side that are connected in the up and down two ends of side plate 18 and lay respectively at side plate 18 vertical with bottom panel 16; One end of upper deck panels 17, side plate 18 and bottom panel 16 all with the surface soldered of riser 15 lower half portions, form L-type structure;
Described assembled plate 3 and lower assembled plate 4 are the identical rectangular plate of structure, on its surface, are processed with mounting hole; Side by side, its upper and lower two ends are fixedly connected with and are integral with lower assembled plate 4 by upper assembled plate 3 respectively for described left socle and right support; Described plural rubber shock absorber is arranged at respectively the both sides of the top of bottom panel 16, the below of upper deck panels 17 and riser 15.
The present invention is because bottom panel 16 and upper deck panels 17 are the double-layer structure in same level not, by in bottom panel 16 and upper deck panels 17, rubber shock absorber being set, thereby owing to existing height difference to form double-layer vibration isolating structure between the rubber shock absorber in two panels; Double-layer vibration isolating structure not only can suppression equipment low-frequency vibration, and can improve the vibration isolating effect to the whole frequency range of equipment, like this can be so that reach good vibration isolating effect in limited space.
Owing to being subject to the restriction of boats and ships bulk, if by support Design structure in aggregates, carried in cabin time, may be more difficult; Therefore the present invention is preferably connected and forms side by side by two symmetrical L-type structural members for carrying the support of required device for vibration insutation.
Support concrete assembly process in left and right is as follows:
First the present invention is stitched together two symmetrical L-type structural members 1 and L-type structural member 2 side by side, and by the hexagon head articulation bolt of assembled plate 3 and assembled plate 4 use M16 * 60, L-type structural member 1 and L-type structural member 2 are positioned to (guarantee that double-layer vibration isolating device enters the conformity of front and back, cabin structure, and then can guarantee that the planeness of each mounting plane of vibration damper and perpendicularity require).Then the hexagon head bolt by M16 * 70 is linked together the splicing panel 5 of L-type structural member 1 and L-type structural member 2.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 15 liang of rear flank of riser, and bottom panel 16 upper surfaces have welded two vibration damper installation panels, and upper deck panels 17 lower surfaces have welded three vibration damper installation panels.After assembling, support forms a pit at base plate middle part, and the equipment of required damping connects 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 a plurality of brackets 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 guaranteeing double-layer vibration isolating apparatus structure intensity, require the weld seam of left and right support key position to carry out ultrasonic flaw detection processing, and its evaluation result meet the requirement of II level.Left and right support and assembled plate are carried out to shot blasting on surface processing simultaneously, and at its surface spraying non-solvent epoxy rust proof paint, and guarantee priming paint thickness of dry film >=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 respectively a plurality of lightening holes on riser and base plate.
The present invention is in actual applications due to the restriction on space, 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 a plurality of rubber shock absorbers is as follows:
The present invention includes 18 rubber shock absorbers, 8 is BE-400 vibration damper for SJA-500 vibration damper wherein 6, 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 surfaces on the support of left and right by bolt, secondly 4 BE-400 vibration dampers 7 are connected with the installation panel 11 on support riser 15 outsides, left and right by bolt, again 4 SJA-500 vibration dampers 8 are connected with the installation panel 12 in left and right bracket bottom deck panels 16 by bolt, then 4 BE-400 vibration dampers 6 connect with the riser 15 inner side installation panels 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 short transverse with SJA-500 vibration damper 8, can reduce double-layer vibration isolating device at it height perpendicular to mounting plane, for environment space narrow and small on ship, after can avoiding equipment to install double-layer vibration isolating device additional, interfere with equipment top hull structure (other system pipeline etc. on bed board and ship), reduce to greatest extent equipment because installing the engineering that involves that double-layer vibration isolating device brings additional.Double-layer vibration isolating device connects structural member 1 and 2 by hexagon head bolt, can for double-layer vibration isolating device aboard ship the cabin stage of entering in installation process provide convenience, reduce into the engineering that involves in the process of cabin.Meanwhile, adopt assembled plate to position double-layer vibration isolating device, can guarantee the conformity of the assembled front and back of double-layer vibration isolating device.
By drainage pump being carried out to the land machine of joining in test room, test, Spot detection after testing, result shows: drainage pump is under declared working condition: the under-chassis vibration acceleration grade decline 35dB that on average shakes, double-layer vibration isolating device vibration isolating effect is remarkable.
