Description
Technical field
The present invention relates to a kind of filler mechanical property testing auxiliary device, be particularly suited for colliery and metal mine are combined
Close the Mechanics Performance Testing of mechanization solid filling coal mining material.
Background technology
Along with China is with solid material comprehensive mechanizations as filler such as spoil, flyash, loess, building wastes
The maturation day by day of solid material filling coal mining technology, the scale to " three times " pressure coal and metal mine that gradually achieves is opened
Adopt, and achieve the effective filling to goaf, effectively raise the rate of extraction of coal resources, solve China " three
Under " mining pressed coal problem, solve the ground stacking problem of garbage spoil, flyash, metal tailings, comprehensively simultaneously
Mechanization solid material filling coal mining technology has important practical significance and wide application prospect.And filler conduct
The requisite part of filling coal mining, the test to its mechanical characteristic contributes to the apparent physics grasping filler
Mechanical property, provides theoretical direction for strata movement after filling mining and surface subsidence control.
Summary of the invention
Technical problem: it is an object of the invention to provide a kind of safe, reliable, efficient mechanical characteristic auxiliary for filler
Test device.
Technical scheme: the filler mechanical property testing auxiliary device of the present invention, including base, the steel that is located on base
Cylinder, is provided with piston and the hollow dowel steel being connected with piston in steel cylinder, described steel cylinder is connected with base flange, on steel cylinder
Portion is symmetrically arranged on two with two hand-held handles, and described piston is slidably matched with steel cylinder, the center, upper surface of piston be provided with
The annular groove that the fastening of hollow dowel steel is connected.
The gap that described piston and steel cylinder are slidably matched is 1～2mm.
Beneficial effect: owing to have employed technique scheme, present invention can apply to comprehensive mechanization solid filling material power
Learn in characteristic test, when the compactingproperties of filler need to be tested, the material that need to test is put in steel cylinder, by executing
Pressure can test different-grain diameter material mechanical property in the case of different compaction force, substantially increases and is compacted filler
The convenience of performance test and simplification, provide theoretical foundation for strata movement after filling mining and surface subsidence control.Its
Simple in construction, safe and efficient, small investment, easy to operate, there is wide applicability.
Accompanying drawing explanation
Fig. 1 is that assembly of the invention duty faces structure chart.
Fig. 2 is assembly of the invention duty plan structure figure.
In figure: 1-steel cylinder, 2-base, 3-piston, the hollow dowel steel of 4-, 5-attal, 6-bolt, the hand-held handle of 7-,
8-round recessed.
Detailed description of the invention
Below in conjunction with the accompanying drawings one embodiment of the present of invention is further described:
The filler mechanical property testing auxiliary device of the present invention, by steel cylinder 1, base 2, piston 3 and hollow power transmission
Bar 4 forms.Steel cylinder 1 lower end and base 2 are by bolt 6 Flange joint, and during method connects, bolt quantity is 8～12
Individual, steel cylinder 1 lateral symmetry two hand-held handles 7 of distribution；Piston 3 is slidably matched with steel cylinder 1 inwall, is slidably matched it
Between gap be 1～2mm, piston 3 can move up and down within steel cylinder 1；Center, piston 3 upper surface is provided with a round recessed 8,
Hollow dowel steel 4 is fixed on the radius of piston 3 upper surface, hollow dowel steel 4 external diameter and round recessed 8 by round recessed 8
Ratio be 1.01～1.03, its fixed effect is preferable.
During work, within the filler 5 that need to test is placed in steel cylinder 1, after smoothing out with the fingers flat filler 5 upper surface, will live
Plug 3 is placed on filler 5, and then fixed piston 3 and hollow dowel steel 4 are in one, execute to hollow dowel steel 4
Adding external force, external force is acted on piston 3 by hollow dowel steel 4, and then is compacted filler, by test
Under the conditions of different compaction force, the change calculations of different filler height goes out the mechanical characteristic of filler, fills for scene
Fill out and rear strata movement and surface subsidence control offer theoretical foundation are provided.
