The creep test device for broken rock samples is characterized in that the worm and gear mechanism comprises a loading weight, a worm, a handle and a worm gear, wherein the handle is installed on the worm; the loading weight is connected to the handle to load the worm; the gear mechanism comprises a small gear and a large gear, wherein the small gear and the worm in the gear mechanism are installed on the same shaft; the screw mechanism comprises a connecting device, a nut and a screw, wherein the large gear and the nut are connected by the connecting device; the nut is driven to rotate by the large gear so as to realize the vertical downward movement of the screw; and the movement of a cylinder is realized by a hinge pin so as to load a creep pressure cylinder. The creep test of the broken rock samples is analyzed by a pressure sensor, a displacement sensor and an external data acquisition system. According to the creep test device disclosed by the utility model, the simple creep test to the broken rock is realized, and the creep test device for broken rock samples has the advantage of simple system structure and is easy to realize.

Description

A kind of broken rock sample creep test device
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.
Description of drawings
Fig. 1 is a kind of broken rock sample creep test device structural representation of the utility model.
Among the figure: the 1-frame, the 2-displacement transducer, the 3-pinion wheel, 4-loads counterweight, 5-worm screw, 6-handle, 7-worm gear, 8-gear wheel, 9-coupling arrangement, 10-nut, 11-leading screw, 12-bearing pin, 13-cylinder, 14-pressure transducer, 15-creep pressure cylinder.
Embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are done further to describe:
Shown in Figure 1, the 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 loading counterweight 4, worm screw 5, handle 6 and worm gear 7; Gear mechanism is made up of pinion wheel 3 and gear wheel 8, and the pinion wheel 3 in the gear mechanism is installed on the same axis with worm gear 7; Screw mechanism comprises coupling arrangement 9, nut 10 and leading screw 11; System also comprises displacement transducer 2, pressure transducer 14 and the external broken creep test of data acquisition system (DAS) analysis.
During work, calculate the weight that loads counterweight 4, be connected to loading counterweight 4 on the handle 6 according to the size of required load; Realization is to the loading of worm screw 5; Power is delivered to worm gear 7 via worm screw 5, and worm gear 7 is coaxial with pinion wheel 3, and power just is delivered to pinion wheel 3 through worm screw 5 like this.Pinion wheel 3 cooperates with gear wheel 8; Gear wheel 8 links together through coupling arrangement 9 with nut 10; Power is delivered to nut 10 in screw mechanism by the worm-and-wheel gear transmission from one channel to another by gear mechanism through the cooperation between above-mentioned parts; Nut 10 cooperates the formation screw mechanism with leading screw 11, and leading screw 11 links together through bearing pin 12 and cylinder 13, limits its rotation for cylinder 13 in the test unit.In the screw mechanism that nut 10, leading screw 11 form, nut 10 relatively rotates with leading screw 11, and nut 10 can only horizontally rotate; Nut 10 rotating band movable wire thick sticks 11 vertically move down like this; And then realize loading to creep pressure cylinder 15, and analyze broken creep test through pressure transducer 14, displacement transducer 2 and external data acquisition system, the invention solves broken simple and easy creep test test; System architecture is simple, realizes easily.
