Description
Technical field
The present invention relates to bituminous coal testing equipment fields, and in particular to a kind of automatic percussion device of bituminous coal sub- dilatometer difficult to understand.
Background technique
The sub- dilation of Austria of bituminous coal is a performance parameter important in bituminous coal coal analysis, and the dilation of coal is used extensively
In the mechanism of coke form ation of Study on Coal, coal quality identification and grade of coal, instruct coking coal and prediction of coke strength etc..GB5450-
Record in 85 " bituminous coal sub- dilatometer tests difficult to understand ", when carrying out sub- dilatometric analysis difficult to understand to bituminous coal, it is most important that first make shaped coal
Pen, the preparation process of coal pen are as follows: the sample 4g prepared weighed, is placed in Chinese pan, it is fast with 0.4ml water lubrication sample
Speed mixes, and prevents with the presence of bubble, then that small-bore one end of mould is downward, is placed on mould pad, and by funnel set
On major part.Under being dialled sample along the side of funnel with ox horn spoon, until filling mould, remaining sample is scraped back in ware.It will
Strike guide plate level is pressed on funnel, is vertically compacted sample (prevent sample spluttering or block strike bar) with strike bar.
Then a whole set of shaping mould is placed under beating device, first under long strike bar strike 4, then adds sample, then hit under 4；According to
Secondary to use three kinds of beating devices of long, medium and short each 2 times, 4 is lower 24 times total every time.
When operating using molding beating device, the top of hammer block is tied up to a rope, the rope other end passes through fixed pulley,
It hand-pulls rope and is pulled to highest point for block is hammered into shape, then loose one's grip, allow and hammer block free-falling into shape, hammering is on strike bar；Then again will
Hammer block is pulled to highest point, carries out next strike, under every strike bar strike 4, then by rope on fixed pulley around several circles, fasten
It is fixed, do not allow hammer block to fall；Second, third root strike bar are changed after sample is added again, under repetition aforesaid operations respectively hit 4,
First rope is unlocked from pulley before changing strike bar strike, hammer block is pulled to highest point, then looses one's grip and is hit, need to repeat 24 altogether
Secondary operation.Based on coal dilatometer experimental standard (GB5450-85) difficult to understand sub-, if beating number of blows not enough or forming the hammer of beating device
The height that block is not stretched to 505mm is fallen, and can all be had an impact to experimental data；And repeatedly will during the test
Hammer block is pulled to highest point, and tie-down, release by rope on pulley repeatedly, this operation are loaded down with trivial details, it has not been convenient to, it is also easy to produce simultaneously
