Specifically, the specimen 21 is inserted from the insertion port 51b of the carrying jig 50, and the conical surface 23 of the specimen 21 is fitted into the fitting holes 33a, 34a of the first and second fitting plates 33, 34. Fix it together. At the same time, both sides of the conical end portion 24 of the specimen 21 are fixed from the outside by a pair of fixing arms 52 provided on the carrying jig 50.

  In this case, the arm member 54 of the fixed arm 52 is manually pushed outward against the elasticity of the urging member 57, and the conical end 24 of the cylindrical main body 22 of the specimen 21 is sandwiched between the conical end portions. The specimen 21 is fixed by engaging the claw end portion 56 of the claw portion 55 with the rear portion of the claw 24. In other words, the claw end 56 of the claw 55 of the arm member 54 of the fixed arm 52 is engaged with the conical end 24 of the carrying jig 50 by using the elastic force of the urging member 57 to carry it. The specimen 21 is mounted inside the jig 50 for use. In this case, the arm member 54 of the fixed arm 52 is pushed outward by a human hand against the elasticity of the urging member 57, but actually, as the transport jig 50 is lowered, The arm member 54 of the fixed arm 52 is pushed outward by the contact between the conical surface 23 of the specimen 21 and the claw portion 55 of the arm member 54.

Next, as shown in FIG.
(3) The carrying jig 50 on which the specimen 21 is mounted is raised to a predetermined height. In this case, the lifting direction of the carrying jig 50 is the vertical direction. That is, as shown in the figure, with the specimen 21 mounted in the carrying jig 50, the first raising / lowering wire 75 and the second raising / lowering wire 76 are raised, so that the carrying jig 50 is Lift to a predetermined height.

  In this case, the lifting and lowering (elevating operation) of the carrying jig 50 can use an elevating device that can elevate a heavy object such as a crane. Specifically, the first elevating wire 75 and the second elevating wire 76 attached to the support portion 38 and the support stay 37 of the carrying jig 50 are simultaneously lifted using a crane.

Next, as shown in FIG.
(4) Remove one lifting / lowering wire (first lifting / lowering wire 75) out of the two first lifting / lowering wires 75 and 76 connected to the carrying jig 50. Specifically, an attachment hook (not shown) of the first lifting wire 75 is removed from the attachment hole 38 a of the support portion 38.

  FIG. 15 shows a state in which the carrying jig 50 is lifted and stopped by only one lifting wire (second lifting wire 76). As shown in the figure, the transport jig 50 has an attachment position (support stay 37) when the second lift wire 76 is the only lift wire that lifts the transport jig 50. ) As a fulcrum and can be stopped in a horizontal state (horizontal direction).

  That is, as shown in FIG. 15, the attachment position of the support stay 37 fixed on the upper surface of the carrying jig 50 is when the carrying jig 50 is lifted by the second lifting wire 76 and stopped laterally. This is the fulcrum position that holds the position of the center of gravity of the carrying jig 50. Thereby, the transportation jig 50 to which the specimen 21 is mounted can be stopped in a stable state at a position in the horizontal direction (sideways state) that is a position to be fixed to the specimen fixing base 10.

And finally, as shown in FIG.
(6) The transport jig 50 to which the specimen 21 is attached is translated to the position where the specimen fixing base 10 is disposed while being lifted by the second lifting wire 76. Specifically, as shown in the figure, the transport jig 50 is transported to the specimen fixing base 10 which is a predetermined transport position in a state where the transport jig 50 is lifted as a horizontal position by the second lifting wire 76.

  In this case, as shown in FIG. 16, the specimen 21 mounted on the transporting jig 50 transported to the position where the specimen fixing base 10 is arranged is fixed to the fixing protrusion of the fixing jig 11 of the specimen fixing base 10. The circular recess 25 formed in the conical end portion 24 is fixed to the portion 12 by fitting.

  As described above, in the method of transporting the specimen 21 using the transportation jig 50, the first and second lifting wires 75 and 76 are connected in a state where the transportation jig 50 equipped with the specimen 21 is lifted in the vertical direction. Only by removing one of the lifting wires, the transporting jig 50 stopped at the vertical position can be set to the horizontal lateral stop position.

  In addition, the transport jig 50 and the specimen 21 that are set to the horizontal lateral stop positions are safely transported to the specimen fixing base 10 at a predetermined position by the parallel movement of the specimen 21. be able to.
