50330-2013), a series of rule such as " rock soil anchor and concrete spraying support engineering legislation " (GB 50086-2015)
Model has made related request, test of the anchor rod drawing test as evaluation anchor pole bearing capacity, in anchor to the detection of construction quality of anchor pole
Very important effect is played in the evaluation of bar construction quality.In the fundamental test and acceptance test of anchor pole, it is required to anchor pole position
Shifting amount measures, and is one of the important parameter for evaluating anchor bolt construction quality.Common displacement measurement side in anchor rod drawing test
Method is to be fixed on dial gauge on bracket by gauge stand, and dial indicator measuring head directly withstands on the enterprising line position shift measurement of anchor pole head.In
It is found in actual tests, in loading procedure, leaves initial position since anchor pole head deflects, the shape of dial indicator measuring head head space
Condition happens occasionally.Therefore, this method detect at the scene in have biggish limitation, do not meet the development trend of industry.
Therefore, in the test of existing anchor rod drawing common displacement measuring device there are anchor pole head deflect leave it is initial
The shortcomings that position, measurement error is big, and dial indicator measuring head head space causes measuring scale and anchor pole to be detached from.
Utility model content
It is drawn the purpose of the utility model is to provide a kind of anchor pole and dials experiment displacement measuring device, had and reduce measurement
Error prevents dial indicator measuring head head space from causing the characteristics of measuring scale is with anchor pole disengaging.
The technical solution of the utility model includes: a kind of anchor pole, which is drawn, dials experiment displacement measuring device, including measuring scale, measuring scale
One end is successively connect with intermediate plate, sleeve, jack piston, jack and wedge block by anchor pole, the other end and branch of measuring scale
Frame connection；Measuring scale includes main scale, and main scale is placed in auxiliary scale, and main scale is connect by flexural pivot with fixes sleeve B, and auxiliary scale passes through flexural pivot
It is connect with fixes sleeve A.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measuring device, is provided with master calibration on the main scale.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measuring device, is provided with secondary scale in the auxiliary scale.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measuring device, is provided with fixed spiral shell on the fixes sleeve A and fixes sleeve B
Silk.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measuring device, and the wedge block is bonded with the inclined-plane of side slope.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measuring device, the fixes sleeve A and fixes sleeve B respectively with anchor pole and branch
One end of frame connects.
The utility model has the beneficial effects that compared with prior art, the utility model structure is simple, convenient test is installed,
The angle that wedge block is mainly used for adjusting between slope surface and anchor pole axis is subtracted with guaranteeing that axis is overlapped with anchor pole axis
Because of measurement error caused by deflecting in few anchor pole loading procedure.Between measuring scale both ends ruler and sleeve be equipped with flexural pivot, and sleeve with
Anchor pole is connected during the test, this guarantees ruler and termination point of anchor rod without departing from.When measuring scale is longer, anchor pole head it is small
Scale deflection influences very little to measurement accuracy and meets requirement of experiment in conjunction with the precision of vernier caliper.Therefore, which, which draws, dials in fact
The characteristics of testing displacement measuring device, have and reduce measurement error, preventing dial indicator measuring head head space from measuring scale and anchor pole being caused to be detached from.
