Description
Technical field
The present invention relates to a kind of dragline type guide vane opening measuring devices.
Background technique
In unit maintenance, need to measure 25%, 50%, 75% and 100% guide vane opening, existing measurement method is：Inspection
It repairs personnel to penetrate into slide calliper rule in the gap of two guide vanes, the subtended angle for adjusting slide calliper rule takes out slide calliper rule to after measuring guide vane opening, uses steel
Board foot measures the distance between slide calliper rule measuring point, as guide vane opening.This method the problem is that：Measurement cannot be same with reading
When complete, measure cumbersome, low efficiency, and take out slide calliper rule measured with Steel Ruler when, there are human error, measurement efficiencies
It is low, and in spiral case, environment is darker, and survey crew's line-of-sight problems increase human error, and measurement accuracy is low.
Summary of the invention
It is an object of that present invention to provide a kind of dragline type guide vane opening measuring devices.
In order to solve the above-mentioned technical problem, a kind of technical solution of the invention is a kind of dragline type guide vane opening measurement dress

End is measured, measurement end is tip, and pin shaft A, pin shaft B are respectively arranged in the middle part of left slide calliper rule, right slide calliper rule, and drawstring electronic ruler and pin shaft A are cut with scissors
It connects, the drawstring end of drawstring electronic ruler and pin shaft B are hinged.
Further, left slide calliper rule, right slide calliper rule inner end are hinged by pin shaft C.
Further, left slide calliper rule, right slide calliper rule equal length, length 400mm-800mm.
Further, pin shaft A, pin shaft B are located at left slide calliper rule and right slide calliper rule outer side center position.
Further, drawstring electronic ruler band statistics have shown and store function, precision 0.1mm, stroke 100mm-
1000mm。
Further, drawstring electronic ruler includes rope sensor, microprocessor, memory, display, rope sensor,
Memory, display are electrically connected with microprocessor, and rope sensor, microprocessor, memory are mounted in shell, it draws
The drawstring end of rope sensor is by shell stretching and hinged with pin shaft B, and on the embedded shell of display, shell and pin shaft A are hinged.
Further, the display is displacement display.
Further, the display is liquid crystal display.
Compared with prior art, the invention has the advantages that：Structure is simple, and design is rationally, easy for operation,
Measurement accuracy is high.
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure：
The left slide calliper rule of 1-；2- drawstring electronic ruler；The right slide calliper rule of 3-；4- pin shaft B；5- pin shaft C；6- pin shaft A.
Specific embodiment
As shown in Figure 1, a kind of dragline type guide vane opening measuring device, including left slide calliper rule, right slide calliper rule, drawstring electronic ruler, it is left
Slide calliper rule, right slide calliper rule inner end are hinged, and left slide calliper rule, right slide calliper rule outer end are measurement end, and measurement end is tip, in the middle part of left slide calliper rule, right slide calliper rule
It is respectively arranged with pin shaft A, pin shaft B, drawstring electronic ruler and pin shaft A are hinged, and the drawstring end of drawstring electronic ruler and pin shaft B are hinged.
In the present embodiment, left slide calliper rule, right slide calliper rule inner end are hinged by pin shaft C.
In the present embodiment, left slide calliper rule, right slide calliper rule equal length, length 400mm-800mm.
In the present embodiment, pin shaft A, pin shaft B are located at left slide calliper rule and right slide calliper rule outer side center position.
In the present embodiment, drawstring electronic ruler band statistics have shown and store function, precision 0.1mm, stroke are
100mm-1000mm。
In the present embodiment, drawstring electronic ruler includes rope sensor, microprocessor, memory, display, drawstring sensing
Device, memory, display are electrically connected with microprocessor, and rope sensor, microprocessor, memory are mounted in shell,
The drawstring end of rope sensor is by shell stretching and hinged with pin shaft B, and on the embedded shell of display, shell and pin shaft A are hinged.
In the present embodiment, the display is displacement display.
In the present embodiment, the display is liquid crystal display.
Before starting to carry out guide vane opening measurement, drawstring electronic ruler need to be connected with the mains.When starting measurement, service personnel
Into in the gap between two guide vanes, the line between left slide calliper rule tip and right slide calliper rule tip keeps horizontal, adjusts left slide calliper rule
Drawstring electronics is directly recorded until left slide calliper rule tip and right slide calliper rule tip are contacted respectively on two guide vane walls with the subtended angle of right slide calliper rule
Numerical value on ruler, since the ontology of drawstring electronic ruler and its drawstring end are respectively hinged at the midpoint of left slide calliper rule, right slide calliper rule, root
According to equal proportion principle, the actual value of guide vane opening is twice that drawstring electronic ruler shows numerical value at this time, can be according to according to the method
The secondary remaining guide vane opening of measurement.
The advantage of the invention is that using drawstring electronic ruler as accurate measuring cell, while measuring guide vane opening
Numerical value can be directly recorded on the display screen on drawstring electronic ruler, avoid error in reading when measurement, easy to use, drawstring electricity
Sub- ruler precision is 0.1mm, and measurement accuracy is high, and is not influenced by light and shade environment, and numerical value is accurate.
