Embodiment
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing clear
Chu, complete description, to be completely understood by the purpose of the present invention, scheme and effect.It should be noted that in situation about not conflicting
Under, the feature in embodiment and embodiment in the application can be mutually combined.The identical accompanying drawing mark used everywhere in accompanying drawing
Note indicates same or analogous part.
As shown in figure 1, the invention provides a kind of clearance measurement mechanism, for measuring PG values and AG values；Its intermediate gap is surveyed
Measuring mechanism includes organic frame, the device for exerting 2 in the frame and gap measuring apparatus 3, is placed in the device for exerting 2
The pressure-detecting device 4 of lower section, the break-make electric detection means 5 for detecting the power on/off of electric horn 10, the device for exerting 2 includes can
The pressure syringe needle 21 moved up and down, the reading of the gap measuring apparatus 3 is moved up and down and changed with the pressure syringe needle 21.
PG values are measured using the clearance measurement mechanism, that is, measure insulating trip 105 and spring leaf 106 inside electric horn 10
Between clearance distance method, include following steps：
Step 1: electric horn 10 is connected into break-make electric detection means 5, and it is fixed on pressure-detecting device 4, then will pressure
The reading of force checking device 4 is reset；
Step 2: driving pressure syringe needle 21 moves down the ring assembly 100, Ran Hou until initial contact electric horn 10
Keep in the state of initial contact, gap measuring apparatus 3 is reset, or record the reading of now gap measuring apparatus 3；
Moved down Step 3: continuing driving pressure syringe needle 21 until break-make electric detection means 5 detects electric horn 10 and broken
Electricity, now records the reading of gap measuring apparatus 3；Have what is be zeroed out for step 2 intermediate gap measurement apparatus 3, now
Reading is exactly the PG values that measurement is obtained；
Step 4: having reading in the record of step 2 intermediate gap measurement apparatus 3, the reading in step 3 is subtracted into step 2
In reading, can also equally obtain PG values.
Because the scope of PG values under normal circumstances is about that 0.15 between 0.25mm, the scope of AG values is about 0.6 to 0.65
Between, thus in view of measurement accuracy the problem of, the preferred dial gauge of the intermediate gap measurement apparatus 3, naturally it is also possible to select thousand
Divide other test devices such as table.Simultaneously in order that dial gauge reading can follow the moving up and down for pressure syringe needle 21 and
Change, the upper end of pressure syringe needle 21 is provided with contact boss 1, the dial gauge is vertical reverse mounted in frame, connects
Touch boss 1 to be located at directly over the dial indicator measuring head, as the pressure syringe needle 21 is moved up and down, contact boss 1 will extrude hundred
Divide table gauge head.
There are two important states in aforementioned four testing procedure, one is the pressure syringe needle 21 and ring assembly
The state of 100 initial contacts, it is mainly judged by the pressure value shown on the pressure-detecting device 4, when display
Pressure value is when within 50g, it is possible to be considered initial contact state, because under this pressure, insulating trip 105 is in pressure
The distance declined under the extruding of power syringe needle 21 is not over 0.01mm, and 0.01mm is just the minimum division value of dial gauge,
It is exactly the measurement accuracy of dial gauge.Another is exactly the state that electric horn 10 is changed into open circuit from path, and it can be used as insulating trip
The important Warning Mark just contacted between 105 and spring leaf 106, because insulating trip 105 and bullet inside electric horn
When also there is gap between reed 106, upper contact 101 and lower contact 102 contact with each other, thus now with the power on/off
The electric horn 10 that detection means 5 is connected is in channel status；As the pressure syringe needle 21 moves down extruding ring assembly 100, absolutely
Gap between embolium 105 and spring leaf 106 will progressively reduce and up to starting to contact, now upper contact 101 and lower contact 102
It will be automatically separated, and electric horn 10 is changed into open circuit from path.Above-mentioned measuring method is exactly by measuring the pressure syringe needle 21
From first state to the displacement of the second state, PG values are measured indirectly.
Substantially similarly, AG values are measured using the clearance measurement mechanism, that is, measures the static iron core 103 inside electric horn 10
The method of distance, also includes following steps between dynamic iron core 104：
Step 1: electric horn 10 is fixed on pressure-detecting device 4, then the reading of pressure-detecting device 4 is reset；
Step 2: driving pressure syringe needle 21 moves down the ring assembly 100, Ran Hou until initial contact electric horn 10
Keep in the state of initial contact, gap measuring apparatus 3 is reset, or record the reading of now gap measuring apparatus 3；
Moved down Step 3: continuing driving pressure syringe needle 21 until the reading of gap measuring apparatus 3 keeps constant and remembered
Now reading under record.Have what is be zeroed out for step 2 intermediate gap measurement apparatus 3, reading now is exactly to measure obtained AG
Value.
Step 4: the record of step 2 intermediate gap measurement apparatus 3 has reading, the reading in step 3 is subtracted in step 2
Reading, can also equally obtain AG values.
Progress can be repeated several times in the measurement of above AG and PG value, according to mathematical modeling, try to achieve average value, or make phase
The curve answered, improves the accuracy of measurement result.
Pressure value is checked for convenience and operation is zeroed out, and the pressure-detecting device 4 is except including pressure sensing
Also include the pressure display unit 42 with display and Protection Counter Functions outside device 41.Meanwhile, electric horn 10 is fixed for convenience
On pressure-detecting device 4, also include electric horn fixed seat 7, the electric horn fixed seat 7 is arranged on the pressure sensor
41 tops.
Specifically, the break-make electric detection means 5 can be digital display universal meter, and in measurement, digital display universal meter two is touched
Pen is pressed on 10 liang of copper plugs of electric horn respectively, and when electric horn 10 is in channel status, digital display universal meter has certain reading, works as electricity
When loudspeaker 10 are in off state, the omnipotent meter reading of digital display is zero.Certainly according to actual conditions, the break-make electric detection means 5
Can also be from the break-make road indicator lamp being connected in series with electric horn 10.When electric horn 10 is in channel status, indicator lamp point
Bright, when electric horn 10 is in off state, indicator lamp extinguishes.While for the ease of observing and measuring, it is generally the case that will be logical
Breaking indicator lamp is arranged in same operation display station with pressure display unit 42.
The pressure syringe needle 21 is moved up and down for convenience, and the device for exerting 2 also includes the driving pressure syringe needle
The 21 rotation handles 23 moved up and down.
Above is the preferable implementation to the present invention is illustrated, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent variations or replace on the premise of without prejudice to spirit of the invention
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
