Description
Technical field
What the present invention relates to is a kind of mechanical testing equipment, is specifically related to a kind of rock mechanics experiment device.
Background technology
So far the direct shear apparatus produced both at home and abroad or simple shear apparatus, its vertical load is 5KN or 10KN, and maximum perpendicular stress is 1.6MPa or 3.2MPa, can not meet the needs of rock mechanics experiment research.Again the heavily stressed simple shear apparatus cost that processing one is brand-new is high.Therefore need to improve existing equipment.
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to be to provide a kind of rock mechanics experiment device, have easy to operate, control performance is good, automaticity advantages of higher, improves the acquisition precision of interface friction force data.
To achieve these goals, the present invention realizes by the following technical solutions: rock mechanics experiment device, comprise the first oil cylinder, upper padding plate, lower bolster, support, back up pad, second oil cylinder, pull bar, substrate, upper roller board, load cap, permeable stone, drag reduction plate, down cut box and lower roller board, the below of the first oil cylinder is disposed with upper padding plate, upper roller board, lower bolster and loading cap, load below cap and be disposed with permeable stone, drag reduction plate, substrate is provided with below drag reduction plate, on the left of substrate, below is disposed with down cut box, lower roller board, down cut box is connected with crossbeam by pull bar, pull bar matches with the second oil cylinder, second oil cylinder is arranged on the supporting plate, support is provided with on the left of back up pad.
As preferably, described substrate is concrete shearing substrate.
As preferably, described lower roller board and back up pad are all arranged on pedestal.
Present invention preserves the parts such as upper lower bolster, back up pad of the roller board of the upper and lower shear box of original device, upper shear box.Redesign and machined permeable stone, cushion block, special simple shear box, load cap, the steel of support and special size and concrete shearing substrate.The ingenious mode of drawing the mode of cutting and acting force and reacting force to balance that equipment makes full use of original equipment eliminates heavy counter-force seat.During shear test, Vertical dimension and horizontal direction hydraulic cylinder are servocontrol.All be equipped with between each surface of contact of whole shear and body remainder and cut the rolling body that rubs, between shear box and soil sample and between shear box and substrate, drag reduction plate is all set, thus friction force is greatly reduced, improve the acquisition precision of interface friction force data.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.

It should be noted that described substrate 8 is concrete shearing substrate.
In addition, described lower roller board 14 and back up pad 5 are all arranged on pedestal 15.
The ingenious mode of drawing the mode of cutting and acting force and reacting force to balance that this embodiment equipment makes full use of original equipment eliminates heavy counter-force seat.During shear test, Vertical dimension and horizontal direction hydraulic cylinder are servocontrol.All be equipped with between each surface of contact of whole shear and body remainder and cut the rolling body that rubs, between shear box and soil sample and between shear box and substrate, drag reduction plate is all set, thus friction force is greatly reduced, improve the acquisition precision of interface friction force data.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
