The portable dynamic test fixture comprises a base, a bearing platform, clamping plates and padding plates which are mutually adhered and placed on the bearing platform, and pin shafts, wherein the base comprises a bottom plate and lateral plates which are fixedly connected; the bearing platform is placed on the base; the pin shafts are respectively connected with the clamping plates and the lateral plates. The portable dynamic test fixture is simple in structure and convenient to mount, can perform testing in a laboratory, is not influenced by the external environmental factors, does not cause interference and damage to the used laboratory, and can be demounted at the same time, so that the device can be mounted and performs testing without constraint by the field as long as a trough is in the laboratory.
Description
Technical field
The utility model relates to a kind of mechanical device for dynamic test, is specifically related to a kind of portable power test fixture, when the method for using dynamic test is determined the frequency of civil engineering material and elastic modelling quantity, can be test specimen fixed constraint reliably is provided.
Background technology
Use the dynamic test technology, can nondestructively determine the characteristic parameters such as the frequency of civil engineering material and elastic modelling quantity, this performance for the evaluation engineering structure is significant, but when carrying out dynamic test, test specimen is difficult to fix usually, thereby affects the frequency test result.
This be because, if test specimen is built in the laboratory, can affect the normal use in laboratory, and, when removing test specimen, can damage the laboratory.If test specimen is built in outdoor, the need for environment around test specimen is strictly controlled, otherwise can cause serious interference to test, and weather conditions can cause equally and can't test or test specimen is caused damage.
In addition, after off-test, in the process of removing test specimen, must cause test specimen to damage due to the test specimen of building by laying bricks or stones, its various performance parameters all will change.If test specimen also will be proceeded subsequent tests, serious deviation will occur in the result of test.
The utility model content
The shortcoming that exists in order to overcome above-mentioned prior art, the utility model provides a kind of portable dynamic test fixture.All test specimen is built on ground when it not be used in each test, just can be reached the effect of bottom fixed constraint by fixture, with the impact on result of the test of the destruction avoiding laboratory and test specimen itself are caused and extraneous factor.
For this reason, the utility model is by the following technical solutions: a kind of portable power test fixture comprises:
Base, described base comprise base plate and the side plate that is fixedly connected with;
Cushion cap, described cushion cap are placed on described base;
The clamping plate and the backing plate that mutually bond, described clamping plate and backing plate are placed on described cushion cap;
Bearing pin, described bearing pin connect respectively described clamping plate and described side plate.
Further, described base plate is mutually vertical with described side plate, and described base plate is fixed by base hold-down screw and ground.
Further, described bearing pin is fixedly connected with described clamping plate by welding, and described bearing pin is fixedly connected with described side plate by bolt.
Owing to having adopted technique scheme, so the utlity model has following beneficial effect:
1, adopt the utility model, the structural dynamic test can be completed in the laboratory, is not subjected to outdoor environment and inside even from weather.
2, avoid carrying out structural dynamic when test, the use in laboratory is caused interference, and after off-test, laboratory environment is damaged.
When 3, avoiding removing test specimen after dynamic test finishes, to the destruction of test specimen, test specimen can continue to be applied to other test.
4, the utility model detachable laboratory geosyncline when not carrying out dynamic test, do not cause interference to the carrying out of other test of laboratory.
5, the utility model is detachable, as long as in the laboratory, geosyncline is arranged, this device is tested with regard to installing, and not limited by the place.
Description of drawings
Fig. 1 is the front view of the utility model fixture.
Fig. 2 is the top view of the utility model fixture.
Fig. 3 is the left view of the utility model fixture.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described, but should limit protection domain of the present utility model with this.
As Figure 1-3, the utility model fixture mainly comprises base plate 11 and side plate 12 by base 1(), base hold-down screw 2, cushion cap 3, bearing pin 4, bolt 5, clamping plate 6 and backing plate 7 form.Wherein, base is formed by fixedly connecting by a base plate 11 and four blocks of side plates 12, four blocks of side plates 12 are mutually vertical with base plate 11 respectively, cushion cap 3 fixed placement are on base, four clamping plate 6 and four backing plates 7 are mutually bonding with adhesive, they are positioned on cushion cap 3 vertically, eight bearing pins 4 couple together the side plate 11 in clamping plate 6 and base respectively, in the present embodiment, bearing pin 4 is fixedly connected with clamping plate 6 by welding, and be fixedly connected with side plate 12 by bolt 5, can regulate distance between clamping plate 6 and side plate 12 by adjusting bolt 5.Base plate 11 can be fixed by base hold-down screw 2 and the ground geosyncline in laboratory.
Before dynamic test, this experiment new device is assembled, base 1 is connected with the laboratory geosynclinal facies by base hold-down screw 2, clamping plate 6 are connected with backing plate 7 use adhesives, by being weldingly connected, clamping plate 6 are connected with base with bolt 5 by bearing pin 4 with backing plate 7 clamping plate 6 with bearing pin 4.
During dynamic test, test specimen is positioned on cushion cap 3, mobile bearing pin 4 is fixing with clamping plate 6, backing plate 7 and bearing pin 4 with bolt 5 after test specimen is clamped by clamping plate 6 and backing plate 7, then carries out the dynamic test test of artificial excitation or environmental excitation.
After dynamic test, unclamp bearing pin 4, test specimen is taken off for other subsequent experimental, the dynamic test of other test specimen can be dismantled or continue on for to fixture on the spot.
The utility model has been avoided carrying out structural dynamic when test and the laboratory is caused has been disturbed or destroy, and reaches the effect of different size test specimen bottom fixed constraint, the damage of having avoided conventional method that test specimen is caused by regulating distance between clamping plate.The utility model is installed easily easy to assembly, can use in the laboratory, has overcome the impact of external environment factor on the structural dynamic test.
The above is only better embodiment of the present utility model, is not to limit practical range of the present utility model.Have in technical field under any and usually know the knowledgeable, within not breaking away from spirit and scope of the present utility model, when being used for a variety of modifications and variations, therefore protection domain of the present utility model should be as the criterion with claims institutes confining spectrum.
