When applying torsion-pulling force compound action, the movable square plate of movement so that test block is located between square plate.With viscous
Knot agent sticks on the termination and rotary shaft of square plate test block, and with cuff banding test block end.Rotary shaft is passed through in square plate
Between roll shaft be fixedly connected with disk, rotary shaft can be rotated by roll shaft.It is wound on disk with a belt and is naturally drooped, in belt
A pallet is hung in free end, counterweight is put on pallet and applies weight.Weight makes belt bear pulling force, and applies disk rotational formation moment of torsion
It is added on test specimen.A support is added on this basis, support is moved on into suitable position and is fixed.Bypassed on support with a belt
Pulley clutch disk center, belt free end is hung a pallet, counterweight is placed on pallet, and pulling force is applied to test block.It is same on two pallets
When place counterweight, to test block apply torsion-pulling force compound action.
When applying the effect of torsion-pressure bonding, it is only necessary to added on the basis of the device under torsion-pulling force compound action
One support, the support has two overhanging cantilevers, by the support toward test block direction move so that two cantilevers just with disk contact.
Belt bypasses pulley Opposite direction connection on the crossbeam with pole bracket, and belt freely terminates pallet, and counterweight is put on pallet.Counterweight weight
After amount makes belt tensioning, cantilever is compressed disk, be applied to pressure effect on test specimen.
Partial devices are only used, the effect of torsion, pulling force, pressure also can be individually applied on test specimen.
Relative to prior art, the present invention has the advantages that：
1st, the device can measure the creep of rock property under torsion-drawing (pressure) compound action；
2nd, various sizes of test block can be tested by mobile support；
3rd, the device is simple to operate, be easy to making.
