Description

  The present invention relates to a measuring device auxiliary device, and more particularly to a measuring device auxiliary device for performing measurement by bringing a measuring device close to or in contact with an object to be measured in a building.

  There are many types of measuring instruments, and their shapes, weights, etc. vary depending on the application. For example, in nuclear power plants, research laboratories, hospitals, etc., radiation measuring devices for measuring radiation are used. Among them, a neutron survey meter for measuring neutron beams measures a neutron dose equivalent rate in a leaky neutron field such as a nuclear facility or an accelerator, and is a necessary device for safety management and the like. With regard to this type of measuring equipment, the penetration rate has improved remarkably, and it is easy and easy to confirm whether the calibration constants attached to the neutron survey meter can be used continuously without the need for special facilities such as radiation shielding rooms. A verification calibrator that can perform this is provided (Patent Document 1).

  FIG. 6 is a schematic perspective view for explaining the usage of the neutron survey meter. The neutron survey meter 30 has a shoulder belt 30c attached to a main body 30a, and an operator hangs the neutron survey meter 30 from his / her shoulder so that a part of the main body 30a abuts on an object to be measured, for example, a pipe 40. The neutron beam emitted from the pipe 40 is measured. In addition to the case where the measurement is performed in contact, neutron beams in the atmosphere may be measured. In that case, a neutron survey meter is installed in the atmosphere. The measured result is displayed on the display unit 30b. The neutron beam is measured by a proportional counter built in the main body 30a, and the measurable range is determined by the accuracy of the built-in proportional counter.

The stick-shaped moving body 14 is inserted into the cylindrical body portion 12a and configured to reciprocate up and down. ing. Therefore, a rack portion 14a for adjusting the amount of protrusion from the cylindrical body portion 12a is formed in the vertical direction (longitudinal direction) of the stick-like moving body 14. In addition, a groove portion 14b is also formed in the longitudinal direction of the stick-like moving body 14 so that it can move up and down smoothly in the cylindrical body portion 12a. Correspondingly, a projection (not shown) that is loosely inserted into the groove 14b is formed in the cylindrical body 12a in the longitudinal direction thereof, and the smooth movement of the stick-like moving body 14 is thereby achieved. Reciprocating movement is realized. A mounting table 16 described later is attached and fixed to the upper end portion of the stick-like moving body 14.

  The moving mechanism portion 18 is provided at the upper end of the cylindrical body portion 12a, and adjusts the amount of protrusion of the stick-shaped moving body 14 from the cylindrical body portion 12, that is, the height of the mounting table 16, and a predetermined height position. It is for fixing with. The moving mechanism 18 includes an adjustment handle 18a, a positioning stopper 18b, and a lock mechanism 18c. The adjustment handle 18a is configured to rotate in conjunction with a pinion gear portion (not shown) that meshes with the rack portion 14a formed in the longitudinal direction of the stick-shaped moving body 14 described above. When rotating in the direction indicated by the arrow A, the pinion gear portion rotates, and the stick-like moving body 14 having the rack portion 14a is moved up and down by the rotation of the pinion gear portion.
