Abstract
The utility model relates to a tester for steel cable tension, which is composed of a bridge circuit, an amplifier, a digital to analog converter, a microprocessor, a display device, a printer and power supply. The tester for steel cable tension is characterized in that a force measuring connecting device is arranged between a hydraulic pressure spiral rope regulating device and a connecting plate. The force measuring connecting device is composed of a main pull rod with an eccentric hole, a left side plate, a right side plate, a shaft pin type force transducer and an eccentric pin for regulating the stress situation of the shaft pin type force transducer. The utility model has the advantages of simple structure, convenient installation, low cost, high measuring precision and long service life.
Description
The utility model is a kind of instrument that detects steel wire rope tension, can carry out detection by quantitative to various steel wire rope tensions.
Along with the intensification of mine and the increase of lifting capacity, many countries have adopted the lifting means of many wire rope, and are like this, also more and more high to the tension force detection requirement of every wire rope.China generally adopts labelling method and the tension force of the ripple method mensuration wire rope that shakes at present, and the shortcoming of these methods is that error is too big.China works out mechanical magnetic effect formula tensiometer and barrel-type resistance wire strain French tensiometer in recent years, though very much progress is arranged than labelling method, the ripple method of shaking, but following weak point is arranged: 1, load-sensing unit is serially connected with and promotes in the erecting by overhang, load-sensing unit is stressed for a long time, shorten the serviceable life of sensor, reduced measuring accuracy; 2, troublesome poeration, particularly zeroing difficulty; 3, can only video data, can not print data.
The purpose of this utility model is to design a kind of steel wire rope tension analyzer accurate, easy to operate, long service life of measuring.
The utility model steel wire rope tension analyzer is made up of bridge diagram, amplifier, digital to analog converter, microprocessor, display, printer and power supply, is characterized between hydraulic screw rope regulator and four connecting plates the dynamometry coupling arrangement being installed.
The dynamometry coupling arrangement, by the eccentric orfice main tie, the eccentric pin of left and right side plate, axial pin type force cell and adjusting axial pin type force cell force-bearing situation is formed.During normal the lifting, the protuberance of eccentric pin is in the below, and sensor does not stress; When measuring tension force, eccentric pin Rotate 180 degree, the protuberance of eccentric pin are in the top, make on the eccentric orfice main tie and move, and cause sensor stressed, reach the purpose of measuring tension force.
The axial pin type force cell is a kind of elastic body load-sensing unit, and it has four to shear stress surface, posts a slice becomes 45 degree (or 135 degree) angle with sensor axis electric-resistance strain ga(u)ge on each shear surface, and each sheet is formed full-bridge circuit as an arm of electric bridge.During dynamometry, the electric-resistance strain ga(u)ge stress deformation, resistance change, the electric bridge out of trim, the output unbalanced signal after amplification and digital-to-analog conversion input MICROCOMPUTER PROCESSING, shows, prints required various data.
The utility model and labelling method, the ripple method of shaking relatively have following advantage:
1, replace forked element with the dynamometry coupling arrangement, not only can be used as web member but also can survey tension force, simple in structure, easy for installation, cost is low.
2, owing to adopted sensor element and bridge diagram, institute's data of surveying are accurate, after MICROCOMPUTER PROCESSING, can show intuitively and print every tension force that wire rope is suffered rapidly.
3, owing to adopted eccentric pin, sensor is not stressed when normal the lifting, thereby improve the serviceable life that measuring accuracy prolongs tension measuring device.
4, this tension measuring device not only can be measured in static state, and the situation of change of the METHOD FOR CONTINUOUS DETERMINATION steel wire rope tension that can be in operation, thereby provides foundation for the grooving diameter of turning cylinder.
The utility model steel wire rope tension analyzer, each sensor can bear 120,000 Ns of heavy weights, and be fine through effect on the lifting means of colliery.
