Description
Technical field
The utility model belongs to engineering technical field of isolation, is related to a kind of disconnected float type earthquake isolating equipment.
Background technology
Under blast shock environment, requirement of engineering takes isolation measure to ensure the safety of internal staff and equipment.Mesh
Before, shock isolation system is largely firmly connected for isolator with shock insulation object, shock insulating foundation three, so can ensure that the stabilization of system
Property, wherein steel wire rope shock isolation system extensive use in engineering.Cable wire shock absorber under compression rigidity soften, have compared with
Good isolation property, but under some particular surroundings, in its tension, rigidity is rapid curing, is unfavorable for shock insulation.Therefore, quick-fried
Under fried load action, the isolation property of cable wire shock absorber reduces, while because of its tension shock isolation system may be caused to damage.
The content of the invention
The purpose of this utility model there is provided a kind of disconnected float type earthquake isolating equipment, for current steel wire rope shock insulation system
It is insufficient existing for system, by reasonably setting, solve in some in particular cases existing steel wire rope shock isolation system extended states
The problem of lower isolation property declines, is easily damaged, while improve isolating affection.
The purpose of this utility model can be adopted the following technical scheme that to realize：
A kind of disconnected float type earthquake isolating equipment, by the fixed plate of fixed shock insulation object, isolated component, universal rotational wheel,
Chassis forms, and the fixed plate be located at topmost, isolated component upper end with being connected below fixed plate, universal rotational wheel top and every
The lower end connection of element is shaken, there is arc surface on described chassis, universal rotational wheel is located on arc surface.
Described fixed plate is disc-shaped structure.
Described chassis is cylindrical structure, and the chassis connecting hole for fixed underpan is provided with cylinder edge.
The arc surface of described chassis upper is circular arc concave shape structure, and circular arc concave edge is in the connecting hole of chassis
Side.
For the utility model due to using technical scheme as described above, the utility model has following superiority：Effectively solution
The problem of isolation property declines, is easily damaged under certainly current steel wire rope shock isolation system extended state, while improve vertically to shock insulation
Effect；Universal rotational wheel is arranged in the cambered surface of chassis, overcomes the vibration influence of horizontal all directions, the horizontal natural frequency of vibration well
It is very low, good damping effect is served, is advantageous to improve comprehensive isolation property.
Brief description of the drawings
The disconnected float type earthquake isolating equipment structural representations of Fig. 1.
In figure：1st, shock insulation plate, 2, isolated component, 3, universal rotational wheel, 4, arc surface, 5, chassis, 6, chassis connecting hole.
Embodiment
The utility model is further described with reference to the accompanying drawings and detailed description：
Explanation the utility model that can be detailed by the following examples, open the purpose of this utility model are intended to protect
All technological improvements in the scope of the utility model.
A kind of disconnected float type earthquake isolating equipment as shown in Figure 1, by fixed plate 1, isolated component 2, universal rotational wheel
3rd, chassis cambered surface 4 and chassis 5 form, and the fixed plate 1 is arranged on the topmost of earthquake isolating equipment, and fixed plate 1 is disc-shaped structure,
The upper end of isolated component 2 is connected below with fixed plate 1, and isolated component 2 can be standard isolator；The top of universal rotational wheel 3 and shock insulation
The lower end connection of element 2, chassis 5 are arranged on the foot of earthquake isolating equipment, and chassis 5 is cylindrical structure, thereon with arc surface
4, arc surface 4 is circular arc concave shape structure；Universal rotational wheel 3 is located on arc surface 4, and universal rotational wheel 3 can be very good to disappear
Except the seismic wave of horizontal direction；The chassis connecting hole 6 for fixed underpan is provided with cylinder edge, passes through chassis connecting hole 6
On the basis of being fixed by bolts to.
In the case of by the impact load, universal rotational wheel 3 is not connected to cambered surface 4, therefore isolated component 2 is not by pulling force
Act on, the downward acceleration of the shock insulation object under Impact Load is not more than acceleration of gravity all the time, while avoids shock insulation
The possibility of element tension damage.Universal rotational wheel 3 can be in the interior edge horizontal rolling of chassis cambered surface 4, therefore the horizontal natural frequency of vibration is very low,
With very high shock insulation rate.
Part not in the detailed description of the invention is prior art.
