Abstract
The invention discloses a displacement meter mounting device which is used for measuring axial displacement of a small component. According to the displacement meter mounting device, an upper steel hoop and a lower steel hoop (1,2) are used as main components. The upper steel hoop and the lower steel hoop are respectively provided with a displacement meter box (3) and a base (4). The steel hoops are fixed on a test block by means of bolts. A measurement length is determined by means of three supporting rods (5) at the central part. A displacement meter is fixed in the displacement meter box. The supporting rods are detached before testing. The displacement meter mounting device has beneficial effects of simple manufacture, convenient mounting and effective recyclability. Furthermore the displacement meter mounting device can accurately measure vertical small displacement of the testing block at multiple aspects.
Description
Art
The present invention relates to a kind of apparatus and method being applied to measure vertical displacement, belong to test measurement apparatus field.
Background technology
In process of the test, structure or component displacement under load action are main test contents, especially the axial displacement of test block is measured, owing to its deformation is little, it is usually no more than a millimeter rank, the displacement meter that existing precision is higher, but owing to corollary apparatus or test method are improper, cause bigger measurement error.
Goal of the invention
It is an object of the invention to the vertical displacement of accurate surveying laboratory test block, reduce measurement error.
Summary of the invention
The present invention is mainly characterized by: upper and lower two steel hoops are fixed on test specimen, fixed displacement meter box on steel hoop, then are arranged on by displacement meter in displacement meter box.
The invention have the benefit that making is simple；It is easily installed；Reusable；Can the vertical micro-displacement of multi-faceted accurate measurement test block.
Accompanying drawing explanation
Fig. 1 is elevation before device；Fig. 2 is elevation after device, and Fig. 3 is upper top view, and Fig. 4 is lower top view, and Fig. 5 is steel hoop, and Fig. 6 is cylindrical support bar plane graph.
Detailed description of the invention
Device the first half:
Determining steel hoop internal diameter according to sample dimensions, cut 2 identical steel hoops 1 and 2 with steel plate, its shape is shown in Fig. 5, and with the identical U-steel component of little Plate Welding three as displacement meter box 3, and welding is positioned on the steel hoop 1 above device, sees Fig. 3.
Device the latter half:
The L-type steel plate that three identical is welded on steel hoop 2 as base 4, sees Fig. 4.
Erecting device:
According to measuring distance, determine the length dimension of support bar 5, the latter half of device is placed on test block and to survey deformed region, fix with bolt 7, support bar 5 is installed, fix with also bolt 8, then the first half of erecting device, makes the first half just put at post upper, fixes with also bolt 8, finally with bolt 7 stationary steel bushing hoop 2, install and see Fig. 1 and Fig. 2 completely.
Metering system:
After device all installs, then displacement meter is placed in displacement meter box, and fixes with bolt 6, finally support bar 5 is all pulled down, just can carry out testing and measuring the axial displacement of test block.
