The upper cover board takes the bowl shape and the base board takes the funnel shape. The bowl-shaped upper cover board and the funnel-shaped base board are buckled in a convex and concave mode. As above technical proposal is adopted, the cushioning latex of the utility model not only has the function that the vibration of the machine transmitted to the base can be reduced as the nuclear safe level of diesel engine electric motor assembly is in normal operation, but also has the function to resist the earthquake, thereby having the advantages of simple structure, safety and reliability.
Description
Technical field
The utility model relates to a kind of rubber pad that is used for the damping of nuclear safe level diesel generating set.
Background technique
At present, the rubber pad used of diesel generating set damping adopts the structure of two metal mounting plate therebetween rubber materials up and down mostly.
This structure is subjected to laterally and is easy to generate the Vertical direction impact force time metal and tearing of rubber junction plane and the destruction of causing equipment when unit.
And the nuclear safe level diesel generating set is the diesel generating set that nuclear power station is used, and requires all to want under extreme environmental conditions the energy proper functioning, and under maximum intensity of earthquake environment, unit is wanted normally to start and to be with to carry.
Therefore, this rubber pad that just requires the damping of nuclear safe level diesel generating set to use singly will not have the effect of damping, also must have earthquake-resistant function.
The model utility content
The purpose of this utility model is to provide a kind of rubber pad that is used for the damping of nuclear safe level diesel generating set, reduce the effect that the unit vibrations are transmitted to the basis when Rubber shock-absorbing pad does not singly have nuclear safe level diesel generating set proper functioning, also have earthquake-resistant function simultaneously.
A kind of rubber pad that is used for the damping of nuclear safe level diesel generating set provided by the utility model is characterized in that: it is made up of upper cover plate and base plate therebetween rubber material, is that a kind of pressure is cut compound shock insulation pad.
At the above-mentioned rubber pad that is used for the damping of nuclear safe level diesel generating set, described upper cover plate is a bowl type.
At the above-mentioned rubber pad that is used for the damping of nuclear safe level diesel generating set, described base plate is the funnel form base plate.
At the above-mentioned rubber pad that is used for the damping of nuclear safe level diesel generating set, the base plane of described funnel form base plate is oval.
At the above-mentioned rubber pad that is used for the damping of nuclear safe level diesel generating set, described bowl type upper cover plate and funnel form base plate are concavo-convex interlocking.
At the above-mentioned rubber pad that is used for the damping of nuclear safe level diesel generating set, be welded with the installation double-screw bolt in described bowl type upper cover plate the inside.
Owing to adopted above-mentioned technical solution, that is: rubber pad can be made up of bowl type upper cover plate and funnel form base plate therebetween rubber material, be that a kind of pressure is cut compound shock insulation pad, therefore, when singly not having nuclear safe level diesel generating set proper functioning, reduces by the utility model yielding rubber pad the effect that the unit vibrations are transmitted to the basis, also have earthquake-resistant function simultaneously, have advantages such as simple in structure, safe and reliable.
Description of drawings
By the description of the following embodiment that a kind of rubber pad that is used for the damping of nuclear safe level diesel generating set of the utility model is put, can further understand purpose of the present invention, specific structural features and advantage in conjunction with its accompanying drawing.
Wherein, accompanying drawing is:
Fig. 1 is that the utility model rubber pad is installed on the example schematic in the nuclear safe level diesel generating set;
Fig. 2 (a) is the sectional view of the utility model rubber pad;
Fig. 2 (b) is the plan view of the utility model rubber pad.
Wherein, the label among the figure is expressed as respectively:
1 is rubber pad;
2 is the unit base;
3 is the basis;
4 for installing base plate;
11 is bowl type upper cover plate;
12 for installing double-screw bolt;
13 is rubber material;
14 is the funnel form base plate.
Embodiment
In Fig. 2 (a)～(b), the utility model is used for the rubber pad of nuclear safe level diesel generating set damping, and it is made up of bowl type upper cover plate 11 and funnel form base plate 14 therebetween rubber materials 13.
Double-screw bolt 12 is installed is welded on bowl type upper cover plate 11 the insides, cast natural rubber 13 between bowl type upper cover plate 11 and funnel form base plate 14, rubber charging quantity 13 is as the criterion with rubber pad design height and funnel form inner chamber regulation filling position, finalizes the design with the mould sulfuration after the rubber filling.
The base plane of described funnel form base plate 14 is oval.
Bowl type upper cover plate 11 and funnel form base plate 14 are concavo-convex interlocking.
As shown in Figure 1, the utility model rubber pad 1 is installed between nuclear safe level diesel generating set unit base 2 and the basis installation base plate 4 on 3, unit base 2 usefulness bolts are connected with the double-screw bolt 12 of the bowl type upper cover plate welding of yielding rubber pad, and the funnel form base plate 14 of yielding rubber pad 1 is fixed by bolts to basis 3 and installs on the base plate 4.
The function that the utlity model has is as follows:
Shock-absorbing function: the yielding rubber pad is made up of bowl type upper cover plate and funnel form base plate therebetween rubber material, is that a kind of pressure is cut compound shock insulation pad.Because rubber material inside is suppressed during resonance the retardation of vibration, vibrate less, free vibration very fast decay, rubber pad has reduced the transmission that shakes.
Antiseismic function: the utility model structure is that a kind of pressure is cut compound rubber vibration isolation cushion, and this structure has advantages of high bearing capacity, lower rigidity and bigger damping ratio, and natural frequency can be accomplished 5Hz.Because very low natural frequency, make beam when earthquake, be not easy to cause resonance, and impulse the very fast decay of bigger damping ratio when making earthquake.Simultaneously, the fine protection rubber material of the distinctive bowl of upper cover plate type design energy, funnel form base plate that rigidity is pure and ellipse plane structure strengthen the installation strength of base plate greatly.Bowl type upper cover plate and the funnel form base plate is concavo-convex interlocks, unit can not cause structural damage because of rubber pad damages yet when rubber pad is destroyed under the extreme case.
In sum, the structural feature of the utility model Rubber shock-absorbing pad:
1. stamping forming bowl type upper cover plate has stronger mechanical strength and bigger surface area; in the bonded area that increases considerably yielding rubber and sheet metal installation component, raising bonding strength; improve the force-bearing situation on its mating face, can well protect yielding rubber.
2. stamping forming funnel form base plate and ellipse plane structure strengthen the installation strength of base plate greatly, also make the external sight of yielding rubber padding more harmonious attractive in appearance simultaneously.
3. singly do not fill yielding rubber between bowl type upper cover plate and funnel form base plate, the while is filling part yielding rubber in the funnel of funnel form base plate also, and this two-part rubber fuses, and has strengthened the bearing capacity and the antiseismic ability of yielding rubber pad.
Though a kind of rubber pad that is used for the damping of nuclear safe level diesel generating set of the utility model is described with reference to current instantiation, but those skilled in the art should be realized that, above example only is to be used for illustrating the utility model, also can make the variation and the modification of various equivalences under the situation that does not break away from the utility model spirit.Therefore, if in connotation scope of the present utility model to the variation of above-mentioned example, modification all will drop in the scope of claims of the present utility model.
