Description
Technical field
The utility model relates to the instrument about cable length measurement in a kind of work progress of power transmission sequence installation interval rod, especially relates to a kind of digital measurement instrument replacing manual measurement.
Background technology
At present, in the work progress of more than 500 kilovolts power transmission sequence installation interval rods at home, cable length measuring instrument utilizes spring force to compress cable, but the bad setting of the size of spring, if spring force is too little, does not press tightly cable, road wheel can skid with cable, and measurement data is forbidden; And spring force is too large, the turnover of cable is very inconvenient again, and the cable accessory of more than 500 kilovolts coordinates by many people, wastes time and energy, poor accuracy.
Utility model content
The purpose of this utility model is to provide a kind of novel cable length measuring instrument, time saving and energy saving, intuitive display is accurate, highly sensitive, long service life, cost are low.
For achieving the above object, the utility model provides a kind of digital cable length measuring instrument, it is characterized in that: comprise a cable hold-down mechanism, a cable travel mechanism, cable length measuring mechanism, a display module, cable length measuring mechanism is made up of photoelectric encoder and microprocessor, photoelectric encoder and the run-in synchronism of cable travel mechanism, photoelectric encoder output pulse signal while cable travel mechanism drives cable to rotate, the pulse signal that microprocessor exports with the mode process photoelectric encoder interrupted, is exported by display module.
Cable hold-down mechanism is above cable, arrange two flute profile contact rollers, and flute profile contact roller connects adjustment bolt by the hat bar being fixed on axle two ends, and adjustment bolt compresses flute profile contact roller through the threaded hole on housing end plug.
End cap one end is flexibly connected with housing, and the other end is fixed on housing by lock pin.
Cable travel mechanism is in lower housing portion and arranges a road wheel below cable, and the transmission shaft of installed rows travelling wheel coordinates synchronous axial system with the rotation axis of photoelectric encoder, and road wheel rolls on cable.
Microprocessor adopts 89C52 single-chip microcomputer.
The utility model, by adding two band-slot contact rollers on end cap, is used for increasing the friction between cable and road wheel, skids to prevent road wheel and cable.Cable is placed on after on road wheel, end cap is covered, adjust and attached cable position with adjustment bolt, increase or reduce contact roller to the normal pressure of cable, thus accurately ensure that road wheel rolls on cable, instead of slide, improve measuring accuracy.Synchronously a photoelectric encoder is installed with road wheel, photoelectric encoder output pulse signal while road wheel rotates on cable, the road wheel photoelectric encoder that turns around exports 1000 pulses, 89C52 single-chip microcomputer is with the output signal of the mode process photoelectric encoder interrupted, then 89C52 single-chip microcomputer is exported by display module after carrying out respective handling to the output signal of photoelectric encoder, realize electronic surveying Presentation Function, time saving and energy saving, easy accessibility, be easy to carry, with low cost, measurement range is wide, measure numerical value accurately directly perceived, easy and simple to handle easy to learn, low to operating environment requirements.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the utility model embodiment electronic surveying Presentation Function block diagram.
In Fig. 1: 1 is end cap, 2 is flute profile contact rollers, and 3 is cables, and 4 is left shells, and 5 is bolts, and 6 is hat bars, and 7 is lock pins, and 8 is the right housings, and 9 is photoelectric encoders, and 10 is road wheels, and 11 is transmission shafts.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model comprises a cable hold-down mechanism, a cable travel mechanism, cable length measuring mechanism, a display module, cable hold-down mechanism is the hat bar 6 connected by adjustment bolt 5 on end cap 1 on flute profile contact roller 2, flute profile plays the effect of guiding, end cap 1 one end is flexibly connected with left shell 4, facilitate the turnover of cable, the other end is fixed on right shell body by lock pin 7.Cable travel mechanism arranges a road wheel 10 between left shell and right shell body and below cable, and can roll on cable 3, the transmission shaft 11 of installed rows travelling wheel 10 coordinates synchronous axial system with the rotation axis of photoelectric encoder 9.Cable length measuring mechanism is made up of photoelectric encoder and single-chip microcomputer 89C52, photoelectric encoder and the run-in synchronism of cable travel mechanism, photoelectric encoder output pulse signal while cable travel mechanism drives cable to rotate, the pulse signal that microprocessor exports with the mode process photoelectric encoder interrupted, is exported by display module LCD1602.
The course of work: open end cap, put into cable, opening power, photoelectric encoder output pulse signal while road wheel rotates on cable, the road wheel photoelectric encoder that turns around exports 1000 pulses, 89C52 single-chip microcomputer, with the output signal of the mode process photoelectric encoder interrupted, is exported by display module LCD1602 after then carrying out respective handling to the output signal of photoelectric encoder.
