Description
Technical field
The present invention relates to a kind of drag-line component cable force measurement device fitting of field of civil engineering, specifically relate to a kind of variable-diameter drag-line clamper and the installation method thereof with enclasping force measurement function.
Background technology
Drag-line component, as the conventional element type in field of civil engineering, is widely used in the rope support systems such as long span stayed-cable bridge, suspension bridge, arch bridge and oblique pull prestressed lattice structure.When the bearing capacity qualification carrying out existing rope supporting structure, need to test the Suo Li of drag-line component.In existing technology, the Cable force test method for existing rope supporting structure mainly contains 3 kinds: Spectrum Method, length variations determination method, magnetic flux method.Spectrum Method utilizes the acceleration transducer be firmly attached on drag-line, the acceleration vibration time-history curves of test drag-line, and solved the vibration frequency of drag-line by software, the recycling vibration frequency of drag-line and the relevance formula of Suo Li try to achieve Cable force value; The method is simple to operate, and testing cost is low, and measuring accuracy can meet engineering test requirement.Length variations determination method measures the length variations amount of Cable section under measurement condition of having demarcated length before test in advance, measurement can utilize the testing element such as displacement meter, fiber-optic grating sensor to realize, utilize length variations gauge to calculate the strain variation value of drag-line, thus obtain the Suo Li changing value of drag-line; The method operation is comparatively simple, and testing cost is lower, and measuring accuracy is higher.Magnetic flux method utilizes drag-line STRESS VARIATION that the principle of its magnetic flux change can be caused to carry out cable tension test, and the method does not need proving installation directly to contact with drag-line, and measuring accuracy is higher, but running program is complicated, and testing cost is high.Spectrum Method in above-mentioned Cable force test method and length variations determination method all need the connection being realized drag-line and testing element by drag-line clamper; therefore the degree of holding with a firm grip (enclasping force) between guarantee drag-line clamper and drag-line is suitable is very important; if enclasping force is inadequate or unstable; then can cause mistake or the comparatively big error of test result; and enclasping force is excessive; then may cause the damage of drag-line corrosion protective covering; or even the damage of drag-line self, thus reduce the serviceable life of drag-line.
At present, the normal drag-line clamper adopted mainly contains flexible elastic cloth belt and rigidity semi-circular cohesion style, no matter but any drag-line clamper does not possess the function that enclasping force is measured, the degree of holding with a firm grip that therefore effectively cannot ensure and be applicable between drag-line; Meanwhile, rigidity semi-circular cohesion style drag-line clamper is generally fixing obvolvent size design, needs, for fc-specific test FC drag-line object customization, not possess versatility, cannot be applicable to the drag-line of different cross section and shape; Flexible elastic cloth belt drag-line clamper is then because strap has relaxation property, and under long-term stretch-draw, its enclasping force meeting continuous decrease, cannot be applicable to the requirement of long-term cable force monitoring.
