Description
Technical field
The utility model relates to a kind of broken rock sample creep test device, is particularly useful for the mechanical property test.
Background technology
Broken creep test research has very important practical sense, under fragmentation that coal mining causes, the lasting external force effect of shelly formation in the rock stratum, top, can produce distortion, and its deflection can influence the size that subsidence is out of shape.Material except instantaneous strain is arranged, also has the slow distortion that continues under the dead load effect, this distortion is called creep.Creep test wants seeking time longer generally speaking, and is short then several days for fragmentation, long then several months, in process of the test, requires the loading accuracy that keeps very high and keeps loading reliable and stable and to reduce experimentation cost extremely important.
Summary of the invention
Technical matters: it is simple that the purpose of the utility model provides a kind of compact conformation, broken safely and efficiently creep test device.
Technical scheme: utility model relates to a kind of broken rock sample creep test device, mainly is made up of worm-and-wheel gear, gear mechanism and screw mechanism.Worm-and-wheel gear comprises and loads counterweight, worm screw, handle and worm gear, and handle and be fixed together worm screw loads counterweight and is connected to the loading that realizes on the handle worm screw; Gear mechanism is made up of pinion wheel and gear wheel, and pinion wheel in the gear mechanism and worm gear are installed on the same axis; Screw mechanism comprises coupling arrangement, nut and leading screw; Gear wheel and nut link together through coupling arrangement, and gear wheel rotates and drives the nut rotation, thereby realizes vertically moving down of leading screw; Realize moving of cylinder through bearing pin, and then realize loading the creep pressure cylinder.Analyze the creep test of broken rock sample through pressure transducer, displacement transducer and external data acquisition system, the invention solves broken simple and easy creep test, system architecture is simple, realizes easily.
Beneficial effect: a kind of broken rock sample creep test device of the utility model, be suitable for the test of mechanical property most, have the following advantages: simple in structure, do not need the additionaling power source just can realize; Can utilize pressure, displacement transducer and external data acquisition system to realize real-time image data.
