The testing device is mainly composed of a horizontal force load transmission system, a load-bearing system and a test system, wherein the horizontal force load transmission system is composed of an upper connecting device, a rocking bar, a connecting pin, a fixed frame, a connecting rod and a side pressure head; and the load-bearing system is composed of an inner wall, upright columns, sleeves and an outer wall, wherein the test system is composed of springs and pressure boxes, and the pressure boxes are externally connected with a data collecting system for collecting the internal pressure. With the adoption of the testing device, the testing and analyzing for the lateral tamping effect of load transmission system are realized, and the testing for tamping effects of different materials under various horizontal forces can be tested, and the device is simple in structure and easy to realize.
Description
Technical field
The present invention relates to test the test unit of compacting effect, especially a kind of Experimental Study On Mechanical Properties for test fragmented rock body side direction compacting effect.
Background technology
Coal is as the main support energy of China, fast development along with Chinese national economy, the industry such as electric power, iron and steel, railway that is positioned at the coal downstream strengthens year by year to the demand of coal, cause in recent years coal mining speed quickening, along with the prolongation of the pit mining time limit with adopt dark extension, a collection of resource exhaustion mine progressively enters residual adopting the stage, and the part mine enters the decline stage, have in addition closing well change the line of production." aging " phenomenon in colliery has become the common problem of Resources-based Enterprises, also having caused enough attention for the mine that the decline tendency is arranged, has in the face of the problem of " three times " (under buildings, under the railway, under the water body) pressure coal that can't exploit with conventional art in most of mining areas.On the other hand, in the quick industrialized process of China, produced a large amount of solid waste every year, these discarded objects occupy cultivated land, contaminated environment.Therefore consider to utilize solid waste displacement coal to realize green exploitation, this is seminar of China Mining University scientific payoffs in recent years, like this and solved the scale mining problem that " three times " press coal, solve again the storage problem of ground solid waste, really realized green exploitation.When carrying out filling mining, utilize production technique to utilize compaction material to carry out filling the coal extraction and to the goaf, the density of compaction material is very important factor like this, it directly has influence on filling effects such as the rock stratum strides, subsidence.The present invention intends when carrying out filling mining, and the compacting effect of compaction material is carried out the test unit of test analysis.
Summary of the invention
Technical matters: the purpose of this invention is to provide a kind of compact conformation, safely and efficiently side direction compacting pilot system.
Technical scheme: the present invention relates to a kind of compact conformation, test safely and efficiently fragmented rock body side direction compacting pilot system.Fragmented rock body side direction compacting pilot system mainly loads transmission system, bearing system and test macro three parts by horizontal force and consists of.Described horizontal force loading system is made of upper coupling arrangement, rocking bar, connecting pin, fixed frame, connecting rod and horizontal pressure head; Described bearing system is made of inwall, column, sleeve and outer wall; Described measuring system is made of spring and pressure cell, and pressure cell can connecting data handling system carries out data acquisition and analysis in addition.The invention solves test and the analysis of the side direction compacting effect of fragmented rock body, can analyze the compacting effect test of different materials under various horizontal force actions, system architecture is simple, realizes easily.
Beneficial effect: the present invention is used for the test fractured rock and concerns problem between the force and deformation under the side load effect, has solved the test difficulty of side direction compacting, the side direction compacting power in the engineering and the relationship analysis between the distortion.Can test the content of two aspects: the one, the power of testing fragmented rock body inside by pressure cell, the 2nd, be the force and deformation of measuring fractured rock by ruler.The whole system compact and reasonable, easy to operate, safe and efficient, small investment have widely practicality to the material side direction in coal filling mining compacting measure of merit, have reference for other mine engineering.
Description of drawings
Accompanying drawing is the test unit structural representation that the present invention tests fragmented rock body side direction compacting effect.
Among the figure: the upper coupling arrangement of 1-, 2-rocking bar, 3-connecting pin, 4-fixed frame, 5-connecting rod, 6-side pressure head, 7-inwall, 8-sleeve, 9-column, 10-outer wall, the broken rock sample of 11-, 12-spring, 13-pressure cell.
Embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are further described:
As shown in the figure, the present invention is used for the test unit of test fragmented rock body side direction compacting effect, mainly loads transmission system, bearing system and test macro three parts by horizontal force and consists of.Described horizontal force loading system is made of upper coupling arrangement 1, rocking bar 2, connecting pin 3, connecting rod 5 and side pressure 6; Described bearing system is made of inwall 7, column 9, sleeve 8 and outer wall 10, and its inwall 7 is made of the identical prose style free from parallelism of some block sizes; Described measuring system is made of spring 12 and pressure cell 13, and pressure cell 13 can collection and the analysis of external data disposal system to carry out pressure.
During work, start drive system, move down by driving upper coupling arrangement 1, by rocking bar 2, fixed frame 4, connecting pin 3, the connecting rod 5 in left side, vertical driving force is converted to the driving force of side direction, driving side pressure head 6 moves right; Promote broken rock sample 11 and carry out the filling simulation to the right, being become by loose condition (of surface) gradually is closely knit.In side pressure 6 repeats to move right the process of the broken rock sample 11 of tamping filling, should be constantly add broken rock sample 11 toward test unit is inner, the density of guarantee filling improves constantly like this.Be accompanied by stowing operation, the inwall of test unit 7 can produce slowly mobile, thereby the springs 12 in the sleeve 8 can produce Slow Deformations, and column 9 can not move radially it to spring 12 is spacing.In the process of filling, can gather by pressure cell 13 external harvesters the stress of broken rock sample 11 inside, also can analyze its force and deformation by spring 12 deflections of 10 of inwall 7 and outer walls.Carry out like this repeated tests, finally solved the problem of test side direction filling compacting effect.
