Abstract
Card jack before a kind of intelligence of direct dynamometry, including displacement transducer, oil cylinder, punching set, support tube, preceding card moveable anchor, baffle plate, it is less than the external diameter of oil cylinder positioned at the external diameter of the support tube of front end, preceding card moveable anchor is arranged on jack front end, force cell is installed on the wall of support tube, the force cell sends out the data measured for use in the deformation data after measurement support tube stress.Its advantage is due to use by the real-time digital display elongation value of stretching of displacement transducer, directly measure the stress of jack pair support tube in real time by force cell, so that measuring data accurately, tensioning quality is effectively raised, it is simple in construction, it is easy to use, jack front end external diameter is smaller, solves the prestressed stretch-draw problem for having space to limit, and preceding card moveable anchor is arranged on jack front end, stretching construction prestress wire is saved, it is simple in construction to be easily installed and safeguard.
Description
Technical field
The present invention relates to prestressing stretching technique field, the preceding card jack of intelligence of more particularly to a kind of direct dynamometry.
Background technology
At present, for the tensioning operation of jack, jack is conversed typically by oil cylinder charge oil pressure is measured
Jacking force, by material, structure and relevant parameter that each component of jack assembly is used during fabrication are according to each factory
Family is manufactured by respective design parameter, therefore, the jacking force for the jack that converted by charge oil pressure, error compared with
Greatly, the tensioning quality directly affected.
The content of the invention
It is an object of the invention to provide a kind of accurate measurement tension data, direct dynamometry simple in construction, easy to use
Intelligence before card jack.
The solution of the present invention is such：
Card jack before a kind of intelligence of direct dynamometry, including displacement transducer, oil cylinder, punching set, support tube, preceding card instrument
Anchor, baffle plate, the external diameter of oil cylinder is less than positioned at the external diameter of the support tube of front end, and preceding card moveable anchor is arranged on jack front end,
Force cell is installed on the wall of support tube, the data measured are sent out and supported for use in measurement by the force cell
Deformation data after cylinder stress.
More specifically technical scheme also includes：Protective cover is installed in force cell periphery.
It is an advantage of the invention that：
1st, due to using by the real-time digital display elongation value of stretching of displacement transducer, directly measured in real time by force cell
The stress of jack pair support tube so that measure data accurately, effectively raise tensioning quality, it is simple in construction, it is easy to use；
2nd, jack front end external diameter is smaller, solves the prestressed stretch-draw problem for having space to limit；
3rd, preceding card moveable anchor is arranged on jack front end, saves stretching construction prestress wire；
4th, it is simple in construction to be easily installed and safeguard.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Reference is in figure：1st, displacement transducer, 2, oil cylinder, 3, punching set, 4, seal plug, 5, protective cover, 6, survey
Force snesor, 7, support tube, 8, preceding card moveable anchor, 9, baffle plate.
Embodiment
As shown in figure 1, the present invention includes displacement transducer 1, oil cylinder 2, punching set 3, support tube 7, preceding card moveable anchor 8, gear
Plate 9, the external diameter of oil cylinder is less than positioned at the external diameter of the support tube 7 of front end, and preceding card moveable anchor is arranged on jack front end, in branch
Force cell 6 is installed, the data measured are sent out and supported for use in measurement by the force cell 6 on the wall for supportting cylinder 7
Deformation data after cylinder stress.Protective cover 5 is installed in the periphery of force cell 6, to protect force cell.
