Abstract
The utility model relates to a high-pressure flexible oil-pressure loading apparatus, comprising a lower part steel plate (1), an upper part ring-shape steel plate (2), a seal ring (3), an oil-resistant rubber cloth (4), screws (5), a transmission steel block (6), an oil inlet (7), and an oil-pressure indicator interface (8), etc. The lower part steel plate (1) and the upper part ring-shape steel plate (2) are closely connected by the screws (5) along the circumference, the seal ring and the oil-resistant rubber cloth are clamped between the two steel plates, the steel plates are pressed by giving oil pressure and making exertion evenly through the rubber cloth, and then the force is transmitted to a loaded test object through the transmission steel block (6), causing the loading boundary of the test object to be stressed evenly. The apparatus is the loading apparatus that the exertion is even and larger, the test object is permitted to have bigger displacement and dislocation on the loading boundary, the uneven deformation can be adapted and the stress centralization does not occur, and the restraint effect of end part is not evident, thereby being able to adapt the test objects with various shapes and sizes.
Description
The utility model relates to the deceleration loading device of a kind of rock mechanics test and physical simulation experiment.
In rock mechanics and physical simulation experiment process in the past, all adopt ordinary jack that the examination body is loaded, make jack with try the body border and be rigidity and contact.At first, be not a pure plane because the examination body loads the border, this makes the place of local minute protrusions stress occur in loading procedure and concentrates, and makes examination body discontinuity, thereby causes testing the serious distortion of gained result.Secondly, for inhomogeneous or comprise the examination body of joint fissure, in loading procedure, because the inhomogeneous deformation of examination body makes the distortion on examination body border also be nonuniformity, and the contact of the rigidity between ordinary jack and the examination body causes being out of shape relative less regional stress and concentrates, and it is obviously less than normal be out of shape the force rate desire load application that bears in bigger zone, makes the test piece end discontinuity, do not reach original boundary load and apply purpose, thereby cause the distortion of test result.The 3rd and since ordinary jack with try to be rigidity between the body and contact, make loading equipemtn fairly obvious, thereby also cause the distortion of test result the end restraint effect of test specimen.Many scholars attempt adding methods such as oiling agent or interpolation multilayer antifriction separation layer between jack and the examination body border and solving this rigidity and contact the end restraint effect of bringing loading.The scholar who also has attempts adopting the influence degree of this end restraint effect of Research on Computer Simulation to test result, then this influence is deducted from test result.But the above-mentioned shortcoming of ordinary jack, rock mechanics worker does not find a kind of satisfied solution always.
The purpose of this utility model provides the deceleration loading device that a kind of flexible contact loads the border, can make the loading border stressed evenly,, the examination end of body do not occur that stress is concentrated and the end restraint effect is not obvious, thereby greatly improves examination body border stress condition and accuracy of experimental results.
For achieving the above object, the doughnut-shaped steel plate that the utility model adopts block plate through scraping and a hollow with screw along combining closely all around, folder one seal ring and oil-proof rubber cloth applies oil pressure and evenly exerts oneself by oil-proof rubber cloth between two block plates, the flexibility that constitutes the uniqueness chamber of exerting oneself; And the power transmission bloom of some independent separate is set on the chamber of exerting oneself, by these power transmission blooms load is uniformly applied on the examination body, thereby forms the flexible border that loads.Change the shape of power transmission bloom, can apply uniform load difform examination body.
Most preferred embodiment of the present utility model is seen accompanying drawing.
Accompanying drawing is the structure erection drawing of the flexible oil pressure deceleration loading device of high pressure.
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in the figure, the flexible oil pressure deceleration loading device of the utility model high pressure is by bottom steel plate (1), upper, annular steel plate (2), seal ring (3), oil-proof rubber cloth (4), screw (5), power transmission bloom (6), oil intake nozzle (7), oil pressure gauge interface compositions such as (8).Bottom steel plate (1) and upper, annular steel plate (2) need be scraped, bottom steel plate (1) is combined closely by screw (5) edge all around with upper, annular steel plate (2), its cooperation place adds a seal ring (3) with leakage proof around oil pocket, folder oil-proof rubber cloth (4) between two steel plates, the two layers of steel plate thickness and the oil-proof rubber cloth number of plies are decided on design load up and down.Circular arc is worn into along need in the inner chamber surrounding of upper, annular steel plate (2), avoids sharp corners damage oil-proof rubber cloth.Bottom steel plate (1) should be than digging 1～2mm all around down at the oil pocket surface of position.Power transmission bloom (6) contacts the wide 7～10cm of a side, forms with " worker " font steel billet that the examination body contacts the wide 7～15cm of a side by a series of thick 1～2cm, high 5～8cm, with oil pocket, power transmission bloom (6) need fill up the whole chamber of exerting oneself.Oil intake nozzle (7) is arranged in an end of oil pocket in the bottom steel plate (1), and oil pressure gauge interface (8) then is arranged in the other end of oil pocket in the bottom steel plate (1).Oil pressure enters oil pocket by oil intake nozzle (7), evenly exert oneself by oil-proof rubber cloth (4), the flexibility that constitutes the uniqueness chamber of exerting oneself, and then by power transmission bloom (6) power transmission to by on the loading examination body, make examination body loading border stressed evenly, can adapt to examination body inhomogeneous deformation and make the examination end of body stress concentration phenomenon not occur, simultaneously because the power transmission bloom is an independent separate, its lateral restraint effect to the examination end of body also can finely be eliminated.This deceleration loading device has solved and has been between ordinary jack and examination body in the past that rigidity contact and the concentrated difficult problem such as fairly obvious of the end restraint effect, the end unbalance stress even end stress that cause, for rock mechanics experiment research provides a cover extremely valuable deceleration loading device, many in the past adopted ordinary jack brand-new result and understanding of being difficult to obtain have been obtained.
The advantage of the gentle attribute oil pressure charger of the utility model high pressure is: the maximum oil pressure that can bear reaches 20MPa, the maximum displacement difference that loads the border can reach 15mm; The width that changes power transmission bloom one end can make This device adapts to the examination body of multiple width, and can adapt to the examination body of various difformities, different size; Whole The height of individual charger is littler, can adapt to the load test in the littler situation of the useful space; This device Simple in structure, easy to maintenance, to exert oneself evenly, the calibration curve linear rule is good; Has higher academic valency Value and application value.
