Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
Referring to figs. 1 to Figure 11
A kind of plumbous extrusion friction composite buffer, comprise a rectangular box 1, the portable plate 2 that two ends pass casing is respectively horizontally arranged with in described casing, wherein one end that described portable plate passes casing is provided with the connecting hole 21 for being connected with outer support members, the leading flank that portable plate is positioned at casing is provided with longitudinal taper protuberance 22, the trailing flank that portable plate is positioned at rectangular box is arranged at intervals with at least two longitudinal arc protuberances 23, the front side being positioned at longitudinal taper protuberance in described casing is provided with the friction plate 3 and friction plate governor motion that trailing flank is the conical surface, the chamber being positioned at longitudinal arc protuberance place in casing is filled with plumbous body 5, the base plate of casing is also provided with the longitudinal bolt 6 for being connected with main structure body.
In the present embodiment, described casing is interconnected through connecting bolt 18 respectively by top board 11, base plate 12, left plate 13, right plate 14, front side board 15 and back side panel 16 and forms, described top board is sandwiched between left and right side plate, and top board is covered on forward and backward side plate upper end, described left and right side plate offers respectively allow portable plate end through longitudinal slot 17, the upper end of this longitudinal slot is curved.The both ends of described base plate are respectively arranged with the protuberance 121 of outstanding left plate and right plate, and described longitudinal bolt is laid on protuberance; Described top board is provided with the inverted U groove 111 for matching with the cambered surface on the upside of portable plate, described base plate is provided with the U-shaped groove 122 for matching with the cambered surface on the downside of portable plate, so that portable plate is stressed rear along inverted U groove and the laterally slip of U-shaped groove.
In the present embodiment, described friction plate governor motion comprises and being arranged in casing and the push pedal 41 be positioned on front side of friction plate, some springs 42 that described push pedal is laid in through interval on friction plate leading flank realize being connected with friction plate, some second springs 43 are provided with between the front side board 15 of push pedal 41 and casing 1, the front side board of casing is also provided with some adjusting bolts 44 penetrating casing and push pedal and abut against, to promote friction plate by adjusting bolt to seesaw, and then by making friction plate move forward and backward with the spring that push pedal is connected with friction plate, and then regulate the distance of tapered protrusion never needed for contact friction plate to contact friction plate, thus realize the size of damping adjusting device frictional force, realize damping adjustable, rigidity is adjustable.
When friction plate and longitudinal taper protuberance distance are 0, portable plate moves at the beginning, plumbous body-portable plate and longitudinal taper protuberance-friction plate are started working simultaneously, when this distance for be greater than 0 certain value time, portable plate movement at the beginning can only drive plumbous body running, friction plate does not now work, until when portable plate moves to this distance value, friction plate just starts to participate in work.Because plumbous body-portable plate does not provide rigidity, this longitudinal taper protuberance-friction plate matches and just provides rigidity, so when this distance is not 0, portable plate is in the one section of displacement started, little situation of shaking in corresponding reality, composite buffer does not provide rigidity, when portable plate moves to longitudinal taper protuberance and friction plate contact of incline plane, corresponding to the good situation in reality, composite buffer starts to provide rigidity.
In the present embodiment, fit tightly, and reduce wear for the ease of portable plate in motion process with the friction plate conical surface, the angle 31 of the conical surface of described friction plate is complementary with the taper surface angle of longitudinal taper protuberance, and the angle of the described friction plate conical surface is 150 ° ~ 175 °.
In the present embodiment, for the ease of the lead after the melting of phase case perfusion in vivo, the top board rear lateral portion of described casing is provided with the fill orifice 112 for pouring into plumbous body, and the steam vent 113 of during perfusion lead, the gas in longitudinal arc protuberance place chamber in casing being discharged, described fill orifice and steam vent are also provided with capping 114, steam vent and fill orifice to be sealed after pouring into lead.
In the present embodiment, described plumbous body to be injected in casing through fill orifice by the lead after melting and is formed after cooling, and plumbous body covers port lid after cooling again, so as in portable plate motion process oscillation damping and energy dissipating.
In the present embodiment, in order to reduce manufacture difficulty, described portable plate is laid in the some longitudinal arc protuberance 23 on steel plate trailing flank by steel plate and interval and the longitudinal taper projection 22 be arranged on steel plate leading flank forms through being welded on steel plate.Described friction plate by near push pedal side two pieces of voussoirs and near portable plate side turn plate through being welded to form, turning plate near the surface of portable plate side is the conical surface.
The using method of this damper: during use, this composite buffer is arranged on the position that agent structure can produce relative deformation, portable plate is connected with outer support members.
Operating principle: when agent structure runs into high wind or earthquake, portable plate and casing will produce relative displacement, and then the longitudinal arc protuberance on drive portable plate trailing flank extrudes the plumbous body in casing, plumbous body is made to be subject to certain extruding force, because the elastic deformation of lead is very little, plumbous body enters plasticity power consumption very soon.If frcition damper part is also started working simultaneously, then frcition damper also participates in power consumption.Thus the energy passing to agent structure is reduced, play the object of protection agent structure.
This composite damping implement body has implemented two kinds of situations:
A kind of when being initial longitudinal taper protuberance be contact with friction plate, so can change pre-applied force by adjusting bolt, realize providing different frictional force, damping, rigidity, the situation that graph illustrates wherein two kinds of rigidity as shown in (a) and (b) in Fig. 8, and in the whole moving process of portable plate, curve shape is similar, just size variation.
When another kind is initial, longitudinal taper protuberance does not contact with friction plate, when so portable plate starts mobile, longitudinal taper protuberance not contact friction plate, then longitudinal taper protuberance moves to contact friction plate, this section needs certain distance, be called contact displacement, when the relative displacement of damper is less than contact displacement, its force-displacement curve as shown in Figure 9; When the relative displacement of damper equals contact displacement, as shown in Figure 10, now portable plate-friction plate is about to start to participate in work its force-displacement curve; When the relative displacement of damper is greater than contact displacement, as shown in figure 11, now portable plate-friction plate participates in work to its force-displacement curve, and provides rigidity.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
