Description
Technical field
The present invention relates to a kind of test bracket, it is especially a kind of suitable for testing coke oven tamping tool tamping briquette when the case that rises
The bracket of power rises case power with soil pressure cell with the use of test coal bin.
Background technique
The case power that rises is a kind of parameter that case structure is often tested, and is the major parameter for reacting box house pressure, is true
Determine the important evidence of tank thickness and box deformation.Coking mixed coal is pressed the size of carbonization chamber by tamping tool, is made firm by ramming into and is slightly less than
Then the briquette made firm by ramming is carried out high-temperature retorting from the side of carbonization chamber push-in carbonization chamber by coal pusher by the briquette of carbonization chamber.
Briquette has to the density made firm by ramming to requiring, and briquette cross-sectional sizes are less than carbonization chamber, otherwise easily cause the coal that collapses, this will
It asks and periodically the case power that rises for making machine-made egg-shaped or honey-comb coal briquets case firm by ramming is detected.The method for testing the case power that rises at present can be divided into according to means of testing difference
Two kinds:
(1) direct method of testing.The case power that rises directly is tested through the method frequently with pre-buried soil pressure cell sensor.Test
Soil pressure cell is mounted on coal bin wall according to certain height and sequence before, then briquette is smash according to making technique firm by ramming
Gu soil pressure cell exports real-time pressure parameter.
(2) indirectly testing method.Indirectly testing method can be using the deformation of test coal bin or survey according to device structure situation difference
The method of examination coal bin supporting point support force carries out indirectly testing and obtains.
But at the scene in test, there are certain drawbacks in both the above method:
(1) data measured using the method that soil pressure cell is directly tested are the most accurate, but tester needs to enter
Box house carries out the installation of soil pressure cell, and very widely used today SCP makes the high 6.5m of all-in-one machine coal bin, wide 50cm firm by ramming, surveys
Examination personnel hardly enter, even if entering reluctantly, in 2 meters of coal bin or more height and position installation pressure cells, there is also very big difficulties.?
When working in coal bin, there is also some potential safety problemss to human respiratory for coal dust.
(2) when the method directly tested using soil pressure cell, after briquette makes molding firm by ramming, soil pressure cell is completely embedded into briquette
It can not take out in the middle.Pressure cell is expensive, and this disposable test will cause the waste of experiment sensor, greatly increases
Testing cost.
(3) signal transmssion line of soil pressure cell is embedded among briquette simultaneously, may cause signal during compacting
Line is damaged, makes signal Transmission or test data inaccuracy.
(4) indirectly testing is carried out according to side outside the enclosure, experimental data can be by patch location, patch quality, cabinet knot
The multifactor impacts such as structure, test data is not accurate enough, repeatable bottom, or even can directly contribute test crash.
Summary of the invention
The present invention is to provide for a kind of coke oven tamping tool and rises case power test bracket, which makes with soil pressure cell cooperation
It is directly tested with to the case power that rises, test data directly, accurately, can take out together bracket and soil pressure cell after test,
Sensor can be recycled, and testing cost has been greatly saved.
To achieve the above object, the case power test bracket the technical scheme is that a kind of coke oven tamping tool rises, including gas
Capsule switch lever, support frame, snap ring, air bag component, cover board, pressure cell locating piece, bottom plate, safety pin lead in support frame as described above
The sliding slot for crossing two sides connects at least one case force test device that rises, and the case force test device that rises is by air bag component, cover board and pressure
Power box locating piece composition is fixedly connected between air bag component and pressure cell locating piece by cover board positioning, and air bag component upper end is logical
The snap ring being mounted in the sliding slot of support frame is crossed to fix;The pressure cell locating piece is provided with soil pressure cell sensor;The pressure
Power box positioning block bottom is fixed by being mounted on the bottom plate of support frame bottom;Air bag switch lever top by safety pin with
The rotating handle of support frame connection, lower part and air bag component connects, and rotating handle connects ball valve by ball valve rod, and ball valve is connected to gas
The high pressure chest and low pressure chamber of capsule component.
Further, the two sides of the air bag component, cover board and pressure cell locating piece are equipped with sliding block, and pass through sliding block and branch
The sliding slot of two sides is cooperatively connected inside support.
Further, the high pressure chest of the air bag component is equipped with air bag inflating port, and low pressure chamber is equipped with flexible sheet, and is equipped with
Air bag gas vent.
Further, when test coal dust make firm by ramming molding coal bin rise case power when, the coke oven tamping tool rises case power test bracket
It is close to coal bin inner wall;Molding coal bin side wall is made firm by ramming when opening coal dust, and the coke oven tamping tool case power test bracket that rises is compacted nothing
When method directly takes out, the air bag switch lever pulls opening ball valve by pulling out safety pin, makes pressure-air by air bag component
High pressure chest enters low pressure chamber, and flexible sheet is heaved, make coke oven tamping tool rise case power test bracket and briquette separation, take out coke oven
Tamping tool rises case power test bracket.
The beneficial effects of the present invention are:
1. soil pressure cell sensor is put into coke oven tamping tool coal bin after being mounted in pressure cell locating piece, can directly survey
The case power that rises is tried, test result is directly, accurately.
2. soil pressure cell sensor and the case power test bracket that rises directly are inserted into coal bin from coke oven tamping tool coal bin top
Portion does not need tester and enters installation soil pressure cell sensor inside coal bin, improves the convenience and safety of installation.
It carries out independent or multiple while installing 3. air bag component, cover board and pressure cell locating piece can be freely combined, test
Freedom degree is high.
4. directly can directly be extracted bracket at the top of coal bin after the completion of test, if briquette compacting is tighter, can open
Air bag switch takes out from coal bin again after releasing bracket.It can be used repeatedly for soil pressure cell sensor and test bracket, greatly
Save testing cost.
5. soil pressure cell signal wire is drawn from internal stent, the contact of not direct and briquette avoids the survey such as signal wire breakage
Try hidden danger.
Therefore, the configuration of the present invention is simple manufacturing cost is low, with soil pressure cell cooperation can rise to coke oven tamping tool case power into
Row directly test, solve the problems, such as before rise case power test in soil pressure cell it is difficult to install and test after can not take out, mention
The high convenience of test, greatly reduces testing cost.
