The size adjustment of track switch gap 300, scale 1 can guarantee the hook on scale 1 under the pulling force effect power of adaptive spring in the process
Tongue 11 blocks always to be placed on the edge of track switch gap 300, is realized automatic adjusument, is avoided and adjusted track switch gap 300 every time
After re-start measurement caused by human error.In maintenance before, operating personnel can not carry out the spacious amount of indication rod 100
Measurement, carrying out blindness adjustment to track switch gap 300 now, can be with people using track switch gap measuring device provided in this embodiment
To act indication rod 100, maximum value and minimum value are measured, spacious momentum can be calculated, whether judgement complies with standard.
There is lines groove (oblique) on column 200 due to checking, to avoid probe 21 from falling into lines groove, optionally, visits
The front end of needle 21 is line style contact structures (transverse direction).The tip designs of probe 21 are line style rather than cusp, spy when avoiding measuring
Needle 21 causes data inaccurate into groove.It is optional to prevent 21 card resistance of probe under the limitting casing for checking column 200 in gap
Ground, the front end of probe 21 are provided with spacer pin 211, and spacer pin 211 is used to prevent 21 card resistance of probe in the limitting casing for checking column 200
In lower gap.
For convenience of operation, optionally, the rear end of scale 1 is symmetrical arranged there are two mounting base 12 (as shown in Figure 4 and Figure 5),
Seperated handle 3 (as shown in Figure 8 and Figure 9) is removably connected in mounting base 12.In use, the hand-held seperated handle 3 of operator,
Can will the track switch gap measuring device it is endways insertion track switch gap 300 at smaller operating space in.Track switch gap measurement
Device uses separate structure, and using different assembling structures, when measurement is not influenced by 300 warning device of track switch gap, Neng Gouzhi
It connects to be placed on indication rod 100 and accurately measure.
Spring catch (not shown), seperated hand are optionally provided in mounting base 12 for convenience of seperated handle 3 is operated
Handle 3 is rotatably dispose in mounting base 12 by spring catch.In the present embodiment, it is provided in mounting base 12 for accommodating seperated hand
First mounting groove 121 of the turning end 31 of handle 3, spring catch are inserted by the mounting hole 122 in mounting base 12, and through seperated hand
Hole at the turning end 31 of handle 3, mounting base 12 are additionally provided with the second mounting groove 123, and for placing U-shaped spring leaf, spring catch is worn
On U-shaped spring leaf.Since seperated handle 3 is rotatably set in mounting base 12, erected by the track switch gap measuring device
Insertion track switch gap 300 at smaller operating space in when, it is easy to operate.Seperated handle 3 is operated for convenience of operator, it can
Selection of land, seperated handle 3 are installed in detachable screwdriver handle (not shown).The installation end 32 of seperated handle 3 is ligule, just
In in removably insertable screwdriver handle, it is convenient for carrying.
To avoid maloperation of the operator in measurement process, optionally, from being provided with concealed type in displacement measurement module
Button, concealed type button is for preventing maloperation.To check the size value measured, optionally, displacement measurement convenient for operator
LCD digital display screen is provided in module, LCD digital display screen can show data in time, adjust track switch gap 300 in time for scene
Size provides convenient.To save electricity, improve service life, displacement measurement module has automatic shut-off function.
Track switch gap measuring device provided in this embodiment mainly comprises the steps that dynamic ruler 2 adaptive in measurement
Under answering spring to act on, until maximum stretch out position；Before measurement, make scale 1 and the opposite sliding of dynamic ruler 2, makes the front end of probe 21 and hook tongue
11 aligned inside verification measurement dead-center position value；When measurement, the probe 21 on dynamic ruler 2 is resisted against and is checked on column 200, then will
Scale 1 drops into the hook tongue 11 on scale 1 in track switch gap 300, stops operation, in adaptive bullet to the sliding of column 200 is checked
The hook tongue 11 that spring acts on lower scale 1 is tightly attached on the edge of track switch gap 300, and the probe 21 on dynamic ruler 2 is resisted against inspection column
On 200, and change adjust automatically with track switch gap 300, is measured by displacement measurement module (such as linear type capacitor grid transducer)
The displacement of scale 1 obtains the size value of track switch gap 300；When needing to adjust the size of track switch gap 300, scale 1 is adaptive
Under the pulling force effect power for answering spring, it can guarantee that the hook tongue 11 on scale 1 blocks always and be placed on the edge of track switch gap 300, realize
Automatic adjusument avoids human error caused by re-starting measurement after having adjusted track switch gap 300 every time.
Track switch gap measuring device provided in this embodiment, overall length 120mm, wide 38mm, thickness 14mm, measurement range 0.7
~25mm.Measurement is convenient, flexibly small and exquisite, adopts a split structure, and convenient for measuring in stenosis, measurement accuracy is high, measurement accuracy
Up to 0.01mm.Number display easy access personnel reading greatly reduces task difficulty, while mentioning for standardized equipment maintenance
Reliable guarantee is supplied.It is not influenced by 300 warning device of track switch gap when measurement, it is accurate to be placed directly on indication rod 100
Measurement.In maintenance before, operating personnel can not measure the spacious amount of indication rod 100, carry out to track switch gap 300 blind
Mesh adjustment, now, using track switch gap measuring device provided in this embodiment, bar 100 can be shown taking human as action schedule, measures maximum
Value and minimum value can calculate spacious momentum, whether judgement complies with standard.Track switch gap measuring device provided in this embodiment can be done
It to 300 state of track switch gap is efficiently and accurately measured, scents a hidden danger in time, prevents accident, guarantee driving safety improves electricity business dimension
The labor intensity and technological progress for repairing personnel have meaning of crucial importance, compensate for the deficiency of 300 manual measurement of track switch gap, mention
The standard value precision of high Gap monitoring, it is comprehensive to improve track switch maintenance quality.
Note that the above is only a better embodiment of the present invention and the applied technical principle.It will be appreciated by those skilled in the art that
The present invention is not limited to specific embodiments here, be able to carry out for a person skilled in the art it is various it is apparent variation, again
