Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is upper plate, 2 is lower shoe, and 3 is spring, and 4 is oil cylinder, and 5 is piston rod, and 6 is first piston, and 7 is guiding, and 8 is the second piston, and 9 is isolation damper, and 10 is top rubber pad, and 11 is bottom rubber pad, and 12 is construction bolt, and 13 is discharge orifice
Embodiment
The novel long period of the resistance to thump buffer of one as shown in Fig. 1, comprise upper plate 1 and lower shoe 2, described upper plate 1 is connected with lower shoe 2 by spring 3, between upper plate 1 and lower shoe 2, be also provided with oil cylinder 4, oil cylinder 4 is connected with lower shoe 2, upper plate 1 is connected with first piston 6 by piston rod 5, first piston 6 is slidably connected at the inside of oil cylinder 4, described piston rod 5 is hollow tubular, lower shoe 2 in oil cylinder 4 is provided with guiding 7, guiding 7 is passed first piston 6 and is slidably connected in piston rod 5 by the second piston 8, the outside of guiding 7 is also provided with isolation damper 9, the two ends of isolation damper 9 are connected with lower shoe 2 with first piston 6 respectively.Described isolation damper 9 is buffering energy-consumption spring, and buffering energy-consumption spring shackle is also connected with lower shoe 2 with first piston 6 respectively around the outside of guiding 7.In the time that equipment is subject to impact energy impact, the upper plate 1 of the buffer being connected with equipment and lower shoe 2 can produce relative displacement due to speed difference, spring 3 is compressed, at whole impact process medi-spring 3 always in confined state, by spring 3 is compressed storage compartment impact energy; Compression starting stage first piston 6 in extreme higher position, in impact process, first piston 6 is subject to the impact of displacement difference and moves to lower shoe 2, the process of moving to lower shoe 2 from extreme higher position at first piston 6, buffer can produce damping force and consume impact energy, damping force is now made up of two-part, wherein a part is the damping force being produced by first piston 6 and the relative movement in oil cylinder 4 gaps, and another part is the damping force being produced by the relative movement in guiding 7 and the second piston 8 and piston rod 5 gaps; And in the process moving downward at first piston 6, isolation damper 9 also can consume a part of impact, buffering energy-consumption spring can provide a reaction force to carry out storage area impact energy after the extruding that is subject to first piston 6, finally offsets the impact energy to equipment.After impact is offset, spring 3 can discharge compression potential energy, and isolation damper 9 meetings consume spring-compressed potential energy, and finally making surge protection equipment reach speed is 0, and makes buffer return to original state.The utility model foundational shock energy of not only can decaying transmits to protected area, and the acceleration that surge protection equipment is born can bear impacts, and equipment can be able to normally be worked after impact; And can support for control object provide static, can control, the structure frequency of adjust system simultaneously; And the design can also realize the vibration and impact isolation of control object and supporting structure, makes control object avoid the excitation of external environment thump.
Oil cylinder 4 is as shown in Figure 1 divided into inside and outside two-layer, internal layer oil cylinder be connected up and down with lineal shape inwall oil cylinder by arc inner wall oil cylinder form, first piston 6 is slidably connected at the inside of arc inner wall oil cylinder, and the side of internal layer oil cylinder and the top of outer oil cylinder all offer discharge orifice 13.The internal diameter of described arc inner wall oil cylinder first increases from top to bottom, after reduce.In the process of impacting from start to end, the speed of first piston 6 also becomes maximum from 0, finally become again 0, so adopting, the gap between oil cylinder 4 and first piston 6 in the design becomes gap design, gap minimum between the incipient stage first piston 6 and the oil cylinder 4 that impact, the process intermediate gap constantly increasing in the speed of first piston 6 also constantly increases, in the time that the speed of first piston 6 reaches maximum, it is maximum that gap between first piston 6 and oil cylinder 4 also reaches, in the time that the speed of first piston 6 reduces, gap between first piston 6 and oil cylinder 4 is continuous gap also, the design guarantees the constant of damping force by the design that becomes gap, thereby the equipment that prevents is excessive because the damping force being subject to changes, and causes the damage of self structure.And when in the process that first piston 6 moves to lower shoe 2, damp liquid in first piston 6 meeting extrusion oil cylinders 4, damp liquid can move to by discharge orifice 13 outside of oil cylinder 4 under the effect of pressure through outer oil cylinder from internal layer oil cylinder 4, after impact finishes, first piston 6 is returned in the process of original position, the in-oil cylinder pressure of internal layer is less than the pressure of oil cylinder 4 outsides, and now damp liquid can flow back into original position from discharge orifice 13 again under the effect of pressure difference.Damp liquid in the utility model also can consume a part of impact in mobile process, thereby increases the passive energy dissipation ability of buffer, better for equipment provides protection.
Upper plate 1 as shown in Figure 1 and the outside of lower shoe 2 are connected with respectively top rubber pad 10 and bottom rubber pad 11, and construction bolt 12 is connected with upper plate 1 through top rubber pad 10.When work, by construction bolt 12, buffer and equipment are fixed, and by add respectively the impact of the vibration producing when top rubber pad 10 and bottom rubber pad 11 carry out minimizing equipment self work on buffer in the outside of upper plate 1 and lower shoe 2.
