Description
Technical field
This utility model relates to a kind of shaking table model device, is specifically related to one and uniformly hits real shaketalle test ground
The assay device of basic mode type.
Background technology
Shaking table model can simulate structure dynamic response under earthquake motion effect more really, therefore, shakes
Dynamic platform model test is the important method that Study of Seismic is dynamic.Shaking table model belongs to small scaled model, model test to be made
Can truly reflect the form of prototype, model except necessary keep geometric similarity with prototype in addition to, also should make model and each material of prototype
Mechanics parameter meets similar requirement.Foundation soil in model, when material, particle diameter, moisture content, grating one timing, native is closely knit
Degree is the important indicator affecting foundation soil mechanics parameter.
At present, the test method hitting real foundation model in shaking table model mainly divides two classes: one is manually to hit on the spot
Base；Two is to drop hammer to hit base on the spot.Manually hitting base major defect on the spot is that the assay device hitting real foundation model is hitting real mistake every time
Foundation model discontinuity in journey, thus cause foundation model easily to produce uneven sedimentation, affect the examination of vibration table model
The result tested, and hit every time real applied to hit strength unbalanced；Dropping hammer and hitting base major defect on the spot is to control accurately
Hit the freely falling body height of true weight hammer every time, and the quality of weight cannot be changed to reach bigger degree of compaction.
Summary of the invention
For above-mentioned problems of the prior art, the purpose of this utility model is, it is provided that one uniformly hits real shaking
Dynamic bench teat tests the assay device of foundation model, and this device can change the quality of compaction hammer, and ensure that and hit real process every time
Middle foundation model uniform force, can also accurately control the freely falling body height of each compaction hammer simultaneously, is beneficial to more real
Simulate structure dynamic response under earthquake motion effect.
In order to realize above-mentioned task, this utility model by the following technical solutions:
A kind of assay device uniformly hitting real shaketalle test foundation model, including shadoof, compaction hammer, quality adjustment cylinder and
Hitting real base plate, compaction hammer is arranged in the middle part of quality adjustment cylinder, is the formation of a circle between such compaction hammer and quality adjustment cylinder
The groove of annular；Compaction hammer and quality adjustment cylinder are all fixed on and hit on real base plate, and the diameter hitting real base plate is adjusted more than quality
The diameter of joint cylinder；Shadoof is fixing with compaction hammer to be connected.
Further, the end of described shadoof is detachably connected with a cross bar, and cross bar and shadoof constitute T-shaped knot
Structure.
Further, the middle part of described cross bar is provided with a level gauge, and level gauge is positioned on compaction hammer axis.
Further, described cross bar one end connects a Telescopic measuring ruler, the telescopic direction of dip stick and cross bar
Vertically.
Further, described assay device also includes the mass of annular, and mass is removably disposed in described
Groove in.
Further, the described bottom hitting real base plate connects rubber blanket.
This utility model has a techniques below feature:
1. this utility model can change the quality of compaction hammer by the quantity controlling placement annular mass, to reach
Hit the degree of compaction that base on the spot is bigger.
2. this utility model is designed with level gauge, it is possible to foundation model uniform force during ensureing every time to hit in fact.
3. this utility model be designed with the dip stick of formula, can accurately control the freely falling body height of each compaction hammer.

Detailed description of the invention
Defer to technique scheme, as shown in Figure 1 to Figure 3, a kind of test uniformly hitting real shaketalle test foundation model
Device, including shadoof 4, compaction hammer 5, quality adjustment cylinder 7 with hit real base plate 8, compaction hammer 5 is placed in the middle part of quality adjustment cylinder 7, this
The groove 6 of an annular it is the formation of between sample compacting hammer 5 and quality adjustment cylinder 7；Compaction hammer 5 and quality adjustment cylinder 7 are the most solid
Being scheduled on and hit on real base plate 8, and hit the diameter diameter more than quality adjustment cylinder 7 of real base plate 8, beneficially compaction hammer 5 is fallen and is hit reality
Time on ground, hit base uniform force on the spot；Shadoof 4 is fixing with compaction hammer 5 to be connected.
This assay device hitting real foundation model that this programme provides, needs experimenter to be lifted to by this assay device
Unclamping hands after certain altitude again makes this device freely falling body drop to hit on the spot on base, and this device is carried by experimenter for convenience
Rising, this programme devises a detachable cross bar 2 being connected to shadoof 4 end, and cross bar 2 and shadoof 4 constitute T-shaped structure.
In order to enable to hit base uniform force on the spot during hitting in fact every time, this programme is provided with one at the middle part of cross bar 2
Individual level gauge 1, level gauge 1 is positioned on compaction hammer 5 axis.When carrying out compaction test, hold cross bar 2, this device is lifted to
Certain altitude, when level gauge 1 (as the used air level) state that is up to the standard, unclamps cross bar 2, makes device freely falling body fall.
This programme devises a Telescopic measuring ruler 3 and is connected to cross bar 2 one end, the telescopic direction of dip stick 3 and cross bar 2
Vertically, i.e. parallel with shadoof 4；When this device is raised, the height mentioned position with hit base on the spot can be measured by dip stick 3
Degree, thus it is accurately controlled the terrain clearance of whole device, reach to regulate the purpose hitting real degree of compaction.
In order to make the quality scalable of compaction hammer 5, this programme provides the mass 10 of a kind of annular, when cross bar 2
After taking apart with shadoof 4, can mass 10 be put in the groove 6 formed between compaction hammer 5 and quality adjustment cylinder 7 along shadoof 4,
Mass 10 quantity put into by control, can regulate the quality of compaction hammer 5.
More preferably, the bottom hitting real base plate 8 in this programme connects rubber blanket 9, can hit the real end during hitting in fact
Plate 8 and hit and play cushioning effect on the spot between base, also makes the dispersion of impact dynamics more uniform simultaneously.
