Description
Technical field
The utility model is related to underground engineering anchor bar suspension device field, and particularly a kind of anchor pole with alarm function allows
Pressure device.
Background technology
With the development of China's economic society, underground mine, tunnel, subway, water power chamber etc. build more and more, more
Engineering be in badly matter condition, the support issues faced therewith are also increasingly protruded.During underground engineering support, anchor
Bar is support materials most widely used, that consumption is most.With being continuously increased for mining depth, roadway surrounding rock usually shows large deformation
The characteristics of, but existing conventional anchor elongation percentage is relatively low, it is impossible to adapt to the large deformation feature of roadway surrounding rock.In addition, locate
Rockbolt stress situation inside roadway surrounding rock can not be showed intuitively again, and existing rockbolt stress electronics, hydraulic pressure amount
Examining system because cost is higher and complex operation can not widely use, cause substantial amounts of amateur survey reading personnel, especially cultural
The relatively low common laborer of degree is difficult to the stressing conditions for judging anchor pole, so that the potential danger of anticipation roadway surrounding rock is unable to, and then
The safety hazards of roadway surrounding rock presence can not be investigated.
A kind of increase resistance pressure-relieving achor bar as Chinese patent 201610256081.0 is disclosed by the body of rod and allow pressure component two parts
Composition, presses the socket place of component to be provided with some grades of latches to limit the displacement of the body of rod by the body of rod with allowing.When anchor pole axial tension
When reaching design load, latch can be cut step by step, so that the body of rod is with allowing pressure component can the relative displacement for sliding setting.This hair
Although bright can provide the working resistance increased step by step by increasing the shear resistance of latch to country rock, it can not embody and enclose
The stressing conditions of anchor pole inside rock, latch anchor pole while cutting step by step can be failed to the support action of country rock, and country rock can be produced
Raw Relative sliding, effect of inertia is possible to bring potential safety hazard.
As Chinese patent 201310461586.7 discloses the detection method and its detection prison of a kind of anchor axial force and moment of flexure
Anchor pole is surveyed, the device on detection anchor bar body by being interval with multiple monitoring cross sections for being machined with threading hole, in each detection
Section body of rod surrounding symmetrically pastes four resistance strain gages, and the axle power of anchor pole and the phase of moment of flexure are obtained by stress-strain test instrument
Close data.The data that the detection of the device is obtained are more accurate, but substantial amounts of connecting line causes many to the installation of anchor pole
Inconvenience, when determining the live anchor pole actual loading situation in tunnel, operating process is complex, and cost is higher, limits its big rule
Mould is used.
Therefore, urgently invention one kind can allow pressure at present, can intuitively show internal stress feelings by external measurement device again
The novel anchor rod suspension device of condition.
The content of the invention
The purpose of this utility model is to provide a kind of anchor pole with alarm function by pressure device, to solve existing anchor pole
The elongation percentage bottom of presence, can not intuitively to show internal stressing conditions existing and the problem of do not possess alarm function, so as to effectively control
The stability of roadway surrounding rock, the potential danger of anticipation roadway surrounding rock investigates safety hazards.
To achieve the above object, the utility model is adopted the following technical scheme that.
A kind of anchor pole with alarm function is by pressure device, it is characterised in that：By allowing pressure system and dynamometry caution system structure
