Description

A kind of magnetic-type digital display wide range three-dimensional machinery crack gauge
Technical field
The utility model relates to engineering project deformation monitoring technical field, in particular to a kind of magnetic-type digital display wide range three-dimensional machine Tool crack gauge.
Background technique
Build deformation joint and be broadly divided into three classes: expansion joint, subsiding crack and aseismic joint, building is under the action of extraneous factor Be easy to produce deformation, cracking caused even to destroy, deformation joint be in response to this and reserved build joint.However building Safety is always the emphasis of national acceptance, therefore deformation joint is envisioned that the importance of building safety, only carries out change The construction working of shape seam, could preferably protect the safety of building.
Occur various cracks in fact, engineering construction is difficult to avoid that and continue to develop, therefore in order to which the safety of structure needs The developmental state of fracture is wanted to be detected in real time, current existing Crack Monitoring instrument is more, each for monitoring building The crack situation of change of segmentation, seperated, between structure relative deformation or rock mass, achieves good effect, but there are also Defect.
It is opposite frequently with the three-dimensional of monitoring concrete structure crack, parting or rock fracture in Process of Engineering Construction Deformation generallys use Three-direction gap detector in the process to realize this purpose, currently used Three-direction gap detector has as follows Several classes: first is that the Three-direction gap detector set on instrument surface gauge length measured using vernier caliper or electronic digital indicator;Two It is the measurement being set to using vernier caliper tailpin, electronic digital indicator tailpin, mechanical dial gauge, digital display centimeter insertion on instrument The Three-direction gap detector in hole.These two types of Three-direction gap detectors in monitoring process, have the disadvantage in that
(1) Three-direction gap detector set on instrument surface gauge length measured using vernier caliper or electronic digital indicator, In monitoring process, vernier caliper or electronic digital indicator need to be stuck between two measurement punctuates, and need to strictly be stuck in measurement mark The highest point of the round punctuate of point, while two punctuate of clamping need to be held.During actual monitoring, the highest point of this round punctuate It should not find, i.e., the maximum distance between two measurement punctuates should not measure, and the position constraint of vernier caliper is poor in observation process, prison Arbitrariness is also big by survey personnel, and monitoring accuracy is poor, in each monitoring, the placement standard disunity of vernier caliper, monitoring personnel Operating habit it is different, the dynamics of different monitoring personnel's clampings two measurement punctuates are different, influence Monitoring Result accuracy and Precision.And measurement need to be repeated several times in such observed pattern, can just search out the maximum distance of point-to-point transmission, inconvenient, time-consuming consumption Power, monitoring efficiency are low.
(2) Three-direction gap detector set on instrument surface gauge length measured using vernier caliper or electronic digital indicator, After any one measurement direction deforms on tri- directions X, Y, Z, the relative position of remaining each punctuate changes, Actual monitoring result is oblique distance, rather than the true strain of tri- direction rectangular coordinate systems of X, Y, Z, and measurement result is non-real real value.
(3) instrument is set to using vernier caliper tailpin, electronic digital indicator tailpin, mechanical dial gauge, digital display centimeter insertion The activity rod of vernier caliper tailpin or dial gauge need to be inserted by the Three-direction gap detector of the measured hole on device in measurement process Measured hole, vernier caliper or dial gauge push against on the outside of measured hole, and such monitoring method need to monitor the minimum value between two measuring points.? During actual monitoring, because vernier caliper tailpin rigidity is small, measurement pore size is bigger than normal, and vernier caliper tailpin has certain inclination Degree, and during vernier caliper or dial gauge abutting measured hole, need whole process hand-held, the hand-held abutting dynamics of different monitoring personnel is not With can cause large effect to measurement result, measurement need to be repeated several times in such observed pattern, can just be searched out between two measuring points Minimum range distance, measurement accuracy is poor, inconvenient, takes time and effort, monitoring efficiency is low.
(4) existing above-mentioned Three-direction gap detector range is small, generally less than 25mm, during monitoring moderate finite deformation crack, amount Journey is insufficient.
