Description
Technical field
The present invention relates to oil and gas pipes anti-seismic technology field, particularly a kind of lamination shears the interformational sliding device of case.
Background technology
Earthquake simulation shaking table is one of important tests equipment of earthquake engineering research work, is mainly used in the seismic environment that simulant building thing, structures etc. may meet with in operational phase, to evaluate its resistance to vibration, reliability and integrity.
At present, conventional in shaketalle test native case roughly has three kinds of forms: rigid box, flexible box and shearing case.Shear case to be usually formed by stacking by 10 ~ 20 layers of steelframe, adjacent two layers can relative sliding, is better than rigid box and flexible box, is considered to ideal model casing in the detrusion of the simulation soil body.At present, major part shearing case generally adopts roller, ball two kinds of modes to realize interformational sliding.
But roller need be placed in slot rolling by roller, when sliding, roller easily skids off outside groove, the easy sideslip of interlayer; That ball is placed in chute in ball-type, but at present the manufacturing accuracy of ball and wearing quality all lower.Therefore, in actual use, roller, that ball-type interformational sliding mode shears in case at lamination the reliability used is all not high.
The object of above-mentioned discussion be to provide may with below by background information relevant for the present invention be described and/or advocate and correlation technique, be beneficial to better understand various aspects of the present invention.Therefore, above-mentioned discussion should be read from this angle, instead of admit prior art.
Summary of the invention
The object of this invention is to provide a kind of lamination shear case interformational sliding device layers between carriage, its friction factor is little, not easily sideslip, solves existing roller, ball-type interformational sliding mode shears the not high technical matters of the reliability that uses in case at lamination.
Embodiments provide the interformational sliding device that a kind of lamination shears case, described lamination is sheared case and is comprised superimposed at least two-layer steel framework, and described interformational sliding device comprises: gathering sill, pickup groove, slide assemblies; Described gathering sill is fixed on the bottom of steel framework described in upper strata, and described pickup groove is fixed on the top of steel framework described in lower floor, and described slide assemblies is arranged in described pickup groove, and wherein, when two-layer described steel framework is superimposed, described pickup groove is inserted in described gathering sill; Wherein, described slide assemblies drives steel framework described in upper strata along described gathering sill slippage, to make the Relative sliding of directed level between two-layer described steel framework.
Preferably, described slide assemblies comprises stationary shaft, deep groove ball bearing; The inwall of described pickup groove has axle draw-in groove, described stationary shaft snaps in described axle draw-in groove, and described stationary shaft upper sleeve through has deep groove ball bearing described at least one.
Preferably, between described deep groove ball bearing and described stationary shaft be interference fit.
Preferably, described interformational sliding device comprises the described slide assemblies of many groups, and the described slide assemblies of many groups is arranged in parallel within described pickup groove.
The embodiment of the present invention, by one or more technical scheme, at least realizes following technique effect or advantage:
1, because the embodiment of the present invention have employed gathering sill, pickup groove, slide assemblies composition interformational sliding device, gathering sill is fixed on the bottom of upper strata steel framework, pickup groove is fixed on the top of lower floor's steel framework, slide assemblies is arranged in pickup groove, when two-layer steel framework is superimposed, pickup groove is inserted in gathering sill, can under the drive of slide assemblies, Relative sliding between adjacent two layers steel framework can along the track in gathering sill, thus Relative sliding is directed, level, therefore sideslip is not easy and the friction factor of Relative sliding is little, to solve existing roller, the technical matters that the reliability that ball-type interformational sliding mode uses in lamination shearing case is not high, achieve lamination shearing case safe and reliable, and the technique effect of stable performance.
2, due to interformational sliding device simple structure that the embodiment of the present invention provides, before shaketalle test, steel framework is superimposed together, ensure that pickup groove is positioned at gathering sill simultaneously, just can make the Relative sliding producing directed level between adjacent two layers steel framework, therefore make, install and apply all convenient.
