The utility model content
In order to overcome defective of the prior art, the utility model proposes a kind of simple structure, the higher limit-type plumbous vibration absorber of shearing of degree of safety.
For this reason, the utility model proposes a kind of limit-type plumbous vibration absorber of shearing, it comprises lead for retractable pencil, upper cover plate, lower cover, sliding panel, limiting plate and two side direction shroudings, described upper and lower cover plate and two side direction shroudings connect into the framework of a left and right sides opening, respectively be provided with a groove on the inwall of described upper and lower cover plate, the upper/lower terminal of described lead for retractable pencil is connected to respectively in the groove of upper and lower cover plate, and the middle part of lead for retractable pencil is equiped with sliding panel, and an end of described sliding panel is equiped with limiting plate.
Wherein, the degree of depth of described groove be upper cover plate or lower cover thickness 1/2-2/3 doubly.
Wherein, described lead for retractable pencil is cylinder or prism.
Wherein, be equiped with connector I on the described sliding panel.
Wherein, all be equiped with connector II on the described upper and lower cover plate.
Wherein, described sliding panel and connector I be by being threaded or welding, and described upper and lower cover plate and connector II are all by being threaded or welding.
The beneficial effects of the utility model are:
1) each member connection structure of limit-type plumbous shearing vibration absorber described in the utility model is simple, and the mild steel that limiting plate and lead for retractable pencil and elastomeric element adopted and plumbous these two kinds of materials obtain easily, and cost is comparatively cheap.
2) the limit-type plumbous vibration absorber of shearing of the present utility model is given full play to the higher flexibility of lead for retractable pencil, ductility, utilizes the plastic deformation energy dissipation of lead for retractable pencil, reaches to consume the energy of under the geological process electric power facility being imported, and reduces earthquake response;
3) the limit-type plumbous vibration absorber of shearing of the present utility model adds a side direction shrouding respectively at the two ends of cover plate, it unites the framework that forms a left and right sides opening with cover plate up and down, make between the upper and lower cover plate sliding panel can only about be free to slide and can not skid off from the side;
4) the limit-type plumbous vibration absorber of shearing of the present utility model is owing to the end at sliding panel adds a limiting plate; make and lead for retractable pencil to be deactivated behind the state when suffering from; limiting plate can be brought into play position-limiting action and avoid occurring runaway condition; thereby the safety of personnel and equipment in the better protection electric power facility, security performance is better.

Embodiment
Below in conjunction with accompanying drawing the limit-type plumbous vibration absorber of shearing of the present utility model is described in further detail.
As shown in Figure 1, the described limit-type plumbous vibration absorber of shearing of this example comprises lead for retractable pencil 1, upper cover plate 2, lower cover 3, sliding panel 4, limiting plate 5 and two side direction shroudings 6.Upper cover plate 2, lower cover 3 be arranged in parallel, and its two ends connect into the framework of a left and right sides opening respectively after affixed by side direction connecting bolt 10 and two side direction shroudings 6; The inwall center of upper cover plate 2 and lower cover 3 respectively is provided with a groove 7, and the degree of depth of groove 7 is upper cover plate 2 or lower cover 3 thickness 1/2-2/3 a times, and the right-hand member of upper cover plate 2 and lower cover 3 is respectively installed a connection piece II, and connected mode can be for being threaded or welding; Sliding panel 4 is provided with a through hole 41 with the groove 7 coaxial settings of upper and lower cover plate, and lead for retractable pencil 1 passes the middle part that makes behind the through hole 41 sliding panel be positioned at lead for retractable pencil, and then the upper/lower terminal of lead for retractable pencil 1 is connected to respectively in the groove 7 of upper and lower cover plate; One end of sliding panel 4 is equiped with a limiting plate 5, the other end and a connection piece I 8 and adopts and be threaded or weld, connector I 8 and connector II 9 can adopt the screw rod of smooth surface or have externally threaded bolt, and the shape of lead for retractable pencil is good to be cylinder or prism.
In use, first according to said structure with upper cover plate 2, lower cover 3, sliding panel 4, limiting plate 5 and two side direction shroudings 6 connect, groove 7 on the upper and lower cover plate has formed a cavity with through hole 41 in the middle of the sliding panel 4, opens the lid that faces groove 7 on the upper cover plate, then with vertical connect to pour into just form lead for retractable pencil in the cavity.After the vibration absorber moulding, connector II 9 on the upper and lower cover plate (adopting connecting bolt in this example) is fixed under the geological process upper end base of the power equipment of the changing of the relative positions relatively, and the connector I 8 on the sliding panel (adopting pre-embedded bolt in this example) being fixed under the geological process relatively, the lower end base of the power equipment of the changing of the relative positions gets final product again.
Sliding panel 4 in the limit-type plumbous shearing vibration absorber of the utility model is when sliding; can make lead for retractable pencil 1 that deformation takes place; and the limiting plate 5 that is fixed on sliding panel 4 one ends cuts little ice under normal operating position; only when reaching the maximum distortion of design, lead for retractable pencil 1 begins to play a role; the utility model has been given full play to the higher flexibility of lead for retractable pencil; ductility; utilize the plastic deformation energy dissipation of lead for retractable pencil; reach and consume the energy of under the geological process electric power facility being imported; reduce earthquake response; when suffering from lead for retractable pencil is deactivated behind the state; limiting plate can spacingly avoid the vibration absorber junction to become no control state, thereby better protects the safety of personnel and equipment in the electric power facility.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present utility model.
