As preferably, the lining anchor clamps comprise the anchor clamps ring flange at top and the square column type test department of anchor clamps ring flange below, and the lining putting hole penetratingly is located at the middle and lower part of said test department.The lining anchor clamps are parts of fixing lining to be measured, and the anchor clamps ring flange is used and is connected other parts, and the lining to be measured that lining putting hole hole wall is opposite in the lining putting hole provides radial compression with simulation external force.
As preferably, the piston rod end of linear cylinder is provided with the piston rod ring flange, and the anchor clamps ring flange docks with the piston rod ring flange and through bolt together.Adopt the method for attachment of ring flange butt joint, both be connected firmly, can guarantee connected two-part right alignment again, guarantee that power can transmit preferably in the axial direction, avoid on other direction, producing component and cause the power transmission efficiency to reduce.
Height such as as preferably, clamp mount comprises two parallel relative risers, and said axis hole is two, is divided on two risers, and the diaxon hole dimension equates, Kong Xin and being on the same axial line.Between two risers certain distance is arranged; Can hold the test department of lining anchor clamps fills in; Behind each axis hole, lining putting hole and the lining centrally aligned to be measured, run through through the lining bolster, lining anchor clamps and lining to be measured can be by two risers and lining bolster at the vertical and horizontal upper limits; During test lining to be measured stablize stressed, thereby guarantee to test accuracy.
As preferably, linear cylinder is a hydraulic servo cylinder.It is actuating medium that hydraulic servo cylinder adopts liquid, and the pressure variation scope is big, and reliability is high, the complicated and diversified stressing conditions that therefore can simulate.Hydraulic servo cylinder adopts closed loop servo control simultaneously, can carry out high-accuracy motion control at aspects such as thrust, speed, positions, makes that the test condition height is controlled.Carry pressure, displacement transducer on the hydraulic servo cylinder, therefore can detect corresponding test parameters.
As preferably, be connected with monitoring computer on the servo controller of said hydraulic servo cylinder., show and preservation correlation test parameter by the condition work of setting through monitoring computer may command hydraulic servo cylinder, be convenient to obtaining and record of test findings.
As preferably, portal frame and clamp mount all are located on the ground.Portal frame and clamp mount are the main supporting bodies of this device, and it is more firm to be located at ground, help the warranty test precision.
The beneficial effect of the utility model is:
Simulation lining radial force condition, the parameters when recording the lining radial force apace is for assessing radially endurance quality of lining exactly.
