[Operation and effect of combined cycle tester 100]
As described above, in the combined cycle tester 100, the rotating body 13 is provided between the sample table 11 that holds the sample S and the carriage 12 on which the sample table 11 is placed, and the rotating body 13 is provided below the carriage 12. 14 are provided. The dolly 12 is provided so as to be adjacent to the test tank 1. Therefore, the carriage 12 on which the sample table 11 is placed moves to the vicinity of the test tank 1 on the guide portion R3 by the rotation of the rotating body 14, and is smoothly transported. Further, the sample table 11 holding the sample S is smoothly carried into the test tank 1 from the guide portion R1 through the guide portion R2 by the rotation of the rotating body 13. Therefore, according to the combined cycle tester 100, even if a sample having a large size or a sample having a large weight is placed on the dolly 12 near the test tank 1 by using a crane or a forklift, for example. If it is placed on the prepared sample table 11, the subsequent loading and unloading into the test tank 1 becomes easy. Further, according to the combined cycle tester 100, since the sample S can be installed on the sample table 11 on the carriage 12 outside the test tank 1, the sample S can be accurately placed at a desired position in the test tank 1. Can be installed. Therefore, for example, even for the sample S to which the wiring XB (see FIG. 3) is attached to measure the performance of the sample, it is possible to easily install it while checking the wiring XB portion and the like in detail. As shown in FIG. 3, if the wiring port X is provided on the wall surface of the test tank 1, the wiring XB connected to the sample S can be connected to a measuring instrument or the like provided outside the test tank 1. Further, if the wiring guide XA is provided on the sample table 11 and the wiring XB is arranged along the wiring guide XA, it is possible to prevent the wiring XB from being caught in the guide portion R2. Further, when the sample table 11 on which the sample S is installed is taken out from the test tank 1 in order to confirm the state of the sample S during the test, it can be easily taken out and can be easily installed again. In this way, a large number of samples S, samples with large dimensions, samples with large weight, samples with wiring attached, etc. are carried into a predetermined location in the test tank 1, or from the test tank 1 to a predetermined location. Can be repeatedly carried out more simply and accurately. In particular, in the case where the height 12H1 of the portion of the guide portion R1 facing the test tank 1 and the height 10H1 of the portion of the guide portion R2 facing the carriage 12 are substantially matched, The movement of the sample table 11 from the carriage 12 to the test tank 1 and the movement of the test tank 1 to the carriage 12 can be performed more easily and quickly.

In the present embodiment, the sample table 11 on which the sample S is placed can be placed on the dolly 12 outside the test tank 1, or the sample table 11 can be removed from the dolly 12 outside the test tank 1. Therefore, even if the sample S has a large size, a large weight, or a complicated shape, the work is easy, and the sample S in the test tank 1 is easily processed. The positioning can be performed easily and accurately using the sample table 11 placed on the carriage 12.

In addition, in the present embodiment, as shown in FIG. 4, the rotating bodies 13 and 14 have concave portions 13U and 14U, and the guide portions R1 to R3 are convex portions that engage with the concave portions 13U and 14U. Each had an RT. For this reason, for example, the corrosive liquid used in the spray corrosion test does not accumulate on the guide portions R1 to R3, and the generation of deposits on the guide portions R1 to R3 can be suppressed, which hinders the transportation of the sample table 11 and the carriage 12. Does not mean

Further, in the present embodiment, the lock pin 11R provided so as to be able to lock the sample table 11 and the guide portion R1 or the sample table 11 and the guide portion R2, and the lock pin that locks the carriage 12 and the guide portion R3. 12R and so on. Therefore, the safety of carrying the sample table 11 from the cart 12 to the test tank 1 and the sample table 11 from the test tank 1 to the cart 12 is improved.

In the present embodiment, the sample table 11 is provided with one opening 11K and one shutter 11S that displaces the opening 11K so that the opening 11K can be opened and closed. At this time, it is advantageous to improve the uniformity of the air flow in the test tank 1.

<2. Application Example of One Embodiment>
FIG. 5 schematically illustrates a schematic configuration example of a combined cycle tester 100A as an application example of the above-described embodiment. The combined cycle tester 100A of the present application example includes a first sample base 11a on which a first sample Sa is mounted and a second sample base 11b on which a second sample Sb is mounted. According to the combined cycle tester 100A, by placing the first sample table 11a and the second sample table 11b on the single trolley 12, the first sample Sa is stored in the test tank 1 and the test tank is tested. The recovery of the first sample Sa from the inside of 1, the accommodation of the second sample Sb in the test tank 1 and the recovery of the second sample Sb from the inside of the test tank 1 can be performed rapidly in sequence. That is, by preparing a predetermined sample table for each sample and placing a predetermined sample on each sample table in advance, the work of exchanging the sample accommodated in the test tank 1 can be promptly performed.

<3. Modification of One Embodiment>
FIG. 6 schematically shows a schematic configuration example of a main part of a combined cycle tester 100B as a modified example of the above embodiment. The present modification is further provided with an adjusting section 19 for adjusting the height and posture of the guide section R3, and a heat capacity adjusting tool 112. The adjusting unit 19 is, for example, a hydraulic damper, and by expanding and contracting by itself, the adjusting unit 19 functions to move the end portion R3B of the guide portion R3, which is far from the test tank 1, toward and away from the floor surface FS in the vertical direction. The heat capacity adjuster 112 has a sample table 11 (here, the first sample table 11A and the second sample table 11B) according to the heat capacity of the sample S (here, the first sample S1 and the second sample S2). Is a member for adjusting the heat capacity of the. Both the first sample stage 11A and the second sample stage 11B have a frame structure including an opening 111. Each of the first sample base 11A and the second sample base 11B is provided with a heat capacity adjuster 112 at the opening 111. For example, one or more heat capacity adjusters 112 selected from a plurality of kinds of heat capacity adjusters 112 made of materials having different heat capacities are attached to the openings 111, or the number of heat capacity adjusters 112 attached to the openings 111 is set. A desired heat capacity can be obtained by adjusting. In the combined cycle tester 100B, the height and posture of the guide portion R3 are adjusted by the adjusting unit 19, so that the height of the carriage 12 and the posture of the carriage 12 with respect to the test tank 1 can be changed as a result. You can do it. For example, when loading the first sample table 11A into the test tank 1, as shown in FIG. 6, the adjusting portion 19 pushes up the end portion R3B of the guide portion R3 that is far from the test tank 1 to perform the test. The guide portion R3 is inclined by making it higher than the end portion R3A near the tank 1. As a result, since the carriage 12 and the guide portion R1 are also inclined like the guide portion R3, even if the first sample stand 11A on which the first sample S1 having a large weight is installed, the first sample stand 11A is mounted on the carriage 12 From the inside to the inside of the test tank 1 easily.

Further, the heat capacity adjusting tool 112 can be attached to the openings 111 of the first sample base 11A and the second sample base 11B, and the heat capacity of the first sample S1 and the heat capacity of the first sample base 11A are combined. It is preferable that the first heat capacity C1 and the second heat capacity C2, which is the sum of the heat capacities of the second sample S2 and the second sample base 11B, are substantially equal. This is because the first heat capacity C1 and the second heat capacity C2 affect the temperature and humidity in the test tank 1. When transitioning to different tests in the combined cycle test, the transition time and the temperature and humidity during the transition also affect the sample. For this reason, it is important to suppress variations in temperature and humidity during the transition with a constant transition time. Therefore, when the first sample S1 in the test tank 1 is replaced with the second sample S2, the total second heat capacity C2 of the second sample S2 and the second sample stage 11B is set to the first sample S1. By making it substantially equal to the total first heat capacity C1 of S1 and the first sample stage 11A, a highly accurate test can be performed.
