Description
Technical field
The present invention relates to a kind of drag-line component cable force measurement device fitting of field of civil engineering, one is concretely related to
Plant the variable-diameter drag-line clamper and its installation method that function is measured with enclasping force.
Background technology
Drag-line component is widely used in long span stayed-cable bridge, hanged as the conventional element type in field of civil engineering
In the rope support systems such as cable bridge, arch bridge and oblique pull prestressed lattice structure.Carrying out the carrying of existing rope supporting structure
, it is necessary to test the Suo Li of drag-line component during power identification.In existing technology, for the Cable of existing rope supporting structure
Force test method mainly has 3 kinds：Spectrum Method, length change determination method, magnetic flux method.Spectrum Method is to utilize to be firmly attached to drag-line
On acceleration transducer, test drag-line acceleration vibration time-history curves, pass through software solve drag-line vibration frequency, then profit
Cable force value is tried to achieve with the vibration frequency of drag-line and Suo Li relevance formula；This method is simple to operate, and testing cost is low, surveys
Examination precision can meet engineering test requirement.Length change determination method is that the Cable section for having demarcated length before test in advance is being surveyed
Length change amount under trial work condition is measured, and measurement can be realized using testing elements such as displacement meter, fiber-optic grating sensors, profit
The strain variation value of drag-line is calculated with length change gauge, so as to obtain the Suo Li changing values of drag-line；This method operation is simpler,
Testing cost is relatively low, and measuring accuracy is higher.Magnetic flux method is to cause the principle of its magnetic flux change using drag-line stress variation
Cable tension test is carried out, this method does not need test device directly to be contacted with drag-line, and measuring accuracy is higher, but operation sequence is complicated,
Testing cost is high.Spectrum Method and length change determination method in above-mentioned Cable force test method are required for clamping by drag-line
Device realizes being coupled for drag-line and testing element, therefore ensures the degree of holding with a firm grip between drag-line clamper and drag-line（Enclasping force）Properly
It is very important, if enclasping force is inadequate or unstable, the wrong or larger error of test result can be caused, and enclasping force
It is excessive, then it may cause the damage of the damage of drag-line corrosion protective covering, even drag-line itself, so as to reduce the use longevity of drag-line
Life.
At present, frequently with the main flexible elastic cloth bag type of drag-line clamper and rigid semi-circular cohesion style, however,
Any drag-line clamper does not possess the function of enclasping force measurement, therefore can not effectively ensure that what is be adapted between drag-line holds with a firm grip
Degree；Meanwhile, rigid semi-circular cohesion style drag-line clamper is usually fixed obvolvent size design, it is necessary to be fc-specific test FC drag-line
Object customization, does not possess versatility, it is impossible to suitable for different cross section and the drag-line of shape；And flexible elastic cloth bag type drag-line clamping
Device then has relaxation property due to strap, under long-term tensioning, its enclasping force meeting continuous decrease, it is impossible to supervised suitable for long-term Suo Li
The requirement of survey.
