Technical field
The utility model is mechanical rock breaking test platform confining pressure device, the ingredient that belongs to the mechanical rock breaking test platform, it can apply two-way confined pressure to sample when using with the mechanical rock breaking test platform, the face rock mass was subjected to the state of terrestrial stress when the rock mechanical equivalent of light excavation was broken in simulation, both can be used for the excavation research of rock tunnel(ling) machine or other excavation machinery, the rock that can be used under unidirectional (or two-way) confined pressure is invaded experimental study again, belongs to rock test machinery technical field.
Background technology
Since the 1970s and 1980s in last century, full face rock tunnel boring machine is developed on an unprecedented scale, speed of application is fast, working environment is friendly, construction economy waits characteristics safely because having, it more and more is subjected to the attention of domestic and international project circle, obtained widely approval, among subway, railway, highway, municipal administration, the water power Tunnel Engineering that more and more widely is applied to various countries built.
The mechanical rock breaking test is widely used in machinery selection, rock breaking mechanism, Optimization of Mechanical Design, optimization construction and mechanical execution speed and the cost forecasting etc. of underground construction machinery excavation project owing to its strong functions.Because the degree of depth of tunnel excavation is increasing, many tunnels are positioned at the tectonic structure complex area, and tunnel and underground construction machinery excavation run into increasing terrestrial stress problem.External existing similar three testing machines still all can not be simulated the state that the face rock is subjected to terrestrial stress at these testing machines at present.And in the TBM of reality digging process, especially in the digging process of deep tunnel, terrestrial stress has remarkable influence to the excavation of rock tunnel(ling) machine or other machinery.The utility model is primarily aimed at this problem, in test sample is applied two-way (or unidirectional) confined pressure, and direct modeling excavation face rock mass is subjected to the state of terrestrial stress.
The utility model content
The utility model proposes a kind of mechanical rock breaking test platform confined pressure test, device mainly comprises electric-control system, Hydraulic Station and mechanical part.This device and mechanical rock breaking test platform be used can the simulation tunnel development machine or the raise-boring machine practice of construction in the middle of the state of the suffered primary stress of face, by changing sample pressure size, research rock tunnel(ling) machine or other broken rock machinery knives are subjected to excavation research under the initial stress state at rock mass, and test findings has very strong directive significance to actual engineering.
In order to achieve the above object, the utility model has been taked following technical scheme.This device comprises: electric-control system 1, Hydraulic Station 2, sample case 3, sample 4, pressure diffusion backing plate 5, hydraulic jack 6, high-strength pull bar and nut 7, oil cylinder are to top board 8, pressure buffer plate 9, cylinder bracket 10.Wherein: electric-control system 1 is connected to Hydraulic Station 2, and Hydraulic Station 2 is connected to the hydraulic jack of placing in the sample case 36;
Regulation is the outside away from a side of sample 4, approaches a side of sample 4 for inboard.Hydraulic jack 6 triplets are placed on the cylinder bracket 10, have two groups, two adjacent in sample case 3 walls are adjacent to layout, install and fix corresponding two group oil cylinders to top board 8 on other two walls relative with placing two groups of hydraulic jacks 6 in the sample case 3, and oil cylinder is to top board 8 and hydraulic jack 6 concentrics; Every group of hydraulic jack 6 and oil cylinder be to inboard all placement forces diffusion backing plate 5 of top board 8, two diffusion backing plate 5 inboards of top board 8 placed one deck pressure buffer plate 9 again placing oil cylinder in addition, at last at the most inboard placement sample 4 of sample case 3; Sample case 3 two relative walls are reinforced with four high-strength pull bars and nut 7.
The utlity model has following advantage:
The utility model can apply confined pressure respectively to sample at the trial on both direction; The big I of confined pressure is regulated as required; Not needing to apply under the situation of confined pressure, can easily pressue device be taken out; After finishing test, can easily sample be taken out; This device simplicity of design is feasible, strong operability.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in the figure, in the utility model in the mechanical rock breaking test platform confining pressure device: electric-control system 1 is connected to Hydraulic Station 2, Hydraulic Station 2 is connected to the hydraulic jack of placing in the sample case 36 by hydraulic hose, is applied the confined pressure of adjustable size during test by 6 pairs of samples 4 of electric-control system 1 control hydraulic jack;
Regulation is the outside away from a side of sample 4, approaches a side of sample 4 for inboard.Hydraulic jack 6 triplets are placed on the cylinder bracket 10, have two groups, and two adjacent walls are adjacent to layout arbitrarily in sample case 3, and every group of hydraulic jack 6 can apply the pressure of maximum 20MPa to sample.Install and fix corresponding two group oil cylinders to top board 8 with bolt on the other two side relative with placing two groups of hydraulic jacks 6 in the sample case 3, require oil cylinder to top board 8 and hydraulic jack 6 concentrics during installation; Every group of hydraulic jack 6 and oil cylinder be to inboard all placement forces diffusion backing plate 5 of top board 8, is used for pressure with every group of hydraulic jack 6 uniformly to the sample transmission; Two diffusion backing plate 5 inboards of top board 8 are placed one deck pressure buffer plate 9 again placing oil cylinder in addition, when spread to sample with elimination power since pressure to spread the stress that backing plate 5 or sample 4 air spots produce concentrated; At the most inboard placement sample 4 of sample case 3, can place maximum specimen size is 1000 * 1000 * 600mm at last; Sample case 3 two relative walls are reinforced with four high-strength pull bars and nut 7, to bear the reacting force of 6 pairs of sample casees 3 of hydraulic jack in the process of the test.
