[utility model content]
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of wireline environment stress screening oscillation test fixture of slab construction to be provided, improved work efficiency widely, made things convenient for the operation when testing, greatly reducing the anchor clamps cost simultaneously.
The wireline environment stress screening oscillation test fixture that the utility model provides; Comprise test slab, test frame, described test slab is set to the rectangular flat that length and width is respectively 200cm～500cm, and test slab is installed on the test frame; The size of test frame and specification are consistent with the length and width of test slab; Through being connected with corresponding aperture on the test frame at test slab respectively, mounting points is set on the test frame, mounting points is fixed on test frame on the test platform; A plurality of fixed orifices that are used for fixing tested cable are set on the test slab, on test slab, connect sensor.
Said mounting points respectively is provided with one on the four edges of test frame.
Described test slab center is provided with center pit and newel, and newel is connected with test platform, and through being connected of center pit and newel, it is more firm to make that test slab and testing stand combine.
Described test slab is connected through screw with test frame, and mounting points is fixed on test frame on the testing stand through screw.
Described test frame is thick to be 3cm～15cm.
The utility model compared with prior art has the following advantages:
The test slab of the utility model is set to rectangular flat; The mounting points of joining with testing stand is set on the framework; Through being connected of center pit and newel, make the utility model anchor clamps have light weight, simple in structure, rigidity is big, frequency response is wide, the good advantage of little, the dynamic transmission characteristic of resonance amplitude; Big, quick and easy for installation, the raising testing efficiency in operating space when the flat framed structure of the utility model test slab is installed.
[description of drawings]
Fig. 1 is the structural representation of the utility model wireline environment stress screening oscillation test fixture.
[embodiment]
For further setting forth the utility model is to reach technological means and the effect that predetermined purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment; To the wireline environment stress screening oscillation test fixture that proposes according to the utility model; Its embodiment, structure, characteristic and effect thereof, explain as after.
The wireline environment stress screening oscillation test fixture that the utility model provides, as shown in Figure 1, these anchor clamps comprise test slab 1, test frame (figure does not show); Wherein, Test slab 1 is set to the rectangular flat that length and width is respectively 200cm～500cm, and test slab 1 is installed on the test frame, and the size of test frame and specification are consistent with the length and width of test slab 1; Thick is 3cm～15cm, and test frame is installed in the below, position of label 2 correspondences on the test slab 1.Through being connected with corresponding aperture on the test frame at test slab 1 respectively.The mounting points that is connected with testing stand is set on the test frame; Mounting points is fixed on test frame on the test platform; The position of label 3 is corresponding one by one on the position of mounting points and the test slab 1; For whole test slab 1 contacts with the steady of testing stand, mounting points respectively is provided with one on the four edges of test frame in the present embodiment.The design of framework has promptly made things convenient for test slab 1 has been fixed on the testing stand; Realized the conversion requirement of 1 three directions of test slab again; A plurality of fixed orifices (figure does not show) that are used for fixing tested cable are set on the test slab 1, and the connector plug of tested cable and this fixed orifice are pegged graft.Simultaneously, on test slab 1, connect sensor (figure does not show), with the vibration level on control or the monitoring test slab 1.
After test slab 1 is fixed in testing stand through mounting points 3 in the present embodiment; Position 2 all is unsettled with interior zone in the test slab 1; Center pit 4 and newel (figure does not show) are set at test slab 1 center, and newel is connected with test platform, through being connected of center pit 4 and newel; It is more firm to make that test slab 1 and testing stand combine, and the not enough situation of test slab 1 rigidity can not occur.
Described test slab 1 is connected through screw with test frame, and mounting points is fixed on test frame on the testing stand through screw.
The utility model anchor clamps are light weight not only, and are simple in structure and rigidity is big, and it is wide to make it have a frequency response, and the resonance amplitude is little, dynamically the good advantage of transmission characteristic.Through repeatedly actual measurement, the acceleration bandwidth of its horizontal direction be-0.26dB～1.13dB, and vertical direction has only-0.17dB～0.66dB, far below the international standard requirement ± 3dB.The operating space was big, quick and easy for installation when the flat framed structure of the utility model test slab 1 was installed, and improved testing efficiency.
