験雰囲気におかれる。The most common type of leap tester measures the amount of deformation of a sample by applying a constant load while heating the sample in air. In addition, there are increasing demands to learn creep characteristics in inert gas and vacuum. For this purpose,
Conventionally, as shown in FIG. 1, there are many devices in which a sample 9 and a force transmitting member 14 are housed in an atmosphere cylinder 2, and the force transmitting member 14 and the atmosphere cylinder 2 are sealed from the atmosphere using an O-ring or a bellows. used. In this type of apparatus, when the sample 9 is attached to or removed from the atmosphere tube 2, it is necessary to lower or increase the temperature of the heating furnace 1. If you want to save time by raising and lowering the temperature of the heating furnace 1, it is possible to do so by, for example, pulling out the atmosphere cylinder 2 in the direction of the force application force, but in this case, if you pull it out vertically, the height of the testing machine will be too high. Therefore, if you pull it out horizontally, the floor space will increase. Furthermore, since the lower seal portion 6 is exposed to high temperatures when passing through the heating furnace, there is a drawback that the O-ring and packing used for the seal are easily damaged. During the test, both ends of the sample 9 are connected to the force transmitting member 2 by screws or pins. Generally, one of the force transmitting members on both sides is fixed by a lower pin 11, and the other is fixed by an upper pin 12.
For example, stress is applied to the lever including the fulcrum 13 of the frame 15 by the force generated by the weight of the weight 10. This stress can also be applied in other ways, such as by a spring. The sample is an atmosphere tube 2 and an upper seal 5.
, separated from the external atmosphere by a lower seal 6, and placed in the target test atmosphere.

。The test atmosphere is often achieved by using the gas manifold lower and the gas outlet 8, but it is also possible to achieve the purpose with only one of them. Also, it is possible to attach it to any part of the sample atmosphere tank such as the atmosphere cylinder at these positions. As mentioned above, O-rings and bellows are often used to seal between the atmosphere cylinder and the force transmission member, but since these are made of rubber-based materials, when the sample is heated to a predetermined temperature in a heating furnace, the high temperature There is a risk of damage. In order to avoid this, it is common to keep the seal portion at a low temperature by flowing cooling water through a portion of the 7-/L via the cooling water pipe 3.4 or the like. As mentioned above, if you try to pull out the atmosphere cylinder while keeping the temperature of the heating furnace at the test temperature, you must first drain the cooling water from this seal, and at that time, remove the sealing O-ring, etc. There was a risk of damage. This kind of loading and unloading of samples needs to be done not only at the start and end of the test, but also frequently, especially when multiple samples are connected in series in an atmosphere cylinder and tested at the same time. Lowering the temperature or damaging the sealing part will significantly impair experimental efficiency.The purpose of the present invention is to eliminate the above-mentioned drawbacks and facilitate the loading and unloading of samples when changing samples.

説明した従来のクリープ試験機と同様である。This invention will be explained with reference to the drawings. As shown in FIG. 2, the heating furnace 1 is divided into two parts. The method of the creep test is the same as the conventional one shown in FIG.
The sample 9 is lifted up via the force transmission member 14, and on the other hand is fixed to the lower pin 11 to apply stress to the sample 9.
The method of applying stress is not limited to this method. Atmosphere cylinder 2
, the seal portion 5.6, and the cooling water pipe 3.4 are similar to the conventional creep tester described above.

3を備えたことにある。The device shown in FIG. 2 is characterized by a slide plate 2 which is attached to the framework 15 using a jig 24 and bolts 25 and has a slide hole in which the atmosphere cylinder 2 is placed.
The reason lies in having 3.

The weight of the slide plate 23 is supported by the slide plate 23. During the test, the atmosphere cylinder 2 was lifted by the weight 10 and was in contact with the slide plate 23, but not in contact with it. Since the weight of the atmosphere cylinder 2 and the like is supported by the slide plate 23, the upper pin 12 and the lower pin 11 can be easily removed. Next, the heating furnace 1 divided into two is opened, and the atmosphere cylinder 2, sample 9, etc. supported by the slide plate 23 are taken out of the heating furnace 1 along the groove provided in the slide plate 23. At this time, there is no need to lower the temperature of the heating furnace 1, and the seal portion 5,
6 does not pass through the high temperature section. Cooling water pipe 3 if necessary
.. It is also possible to leave the pipes 4, gas inlet/output lower, 8, etc. connected. The atmosphere cylinder 2, sample 9, etc. taken out of the furnace are cooled in the air and then decomposed, and the sample 9 is taken out. When placing Sample 9 into the testing machine, follow the above procedure in reverse. It is also possible to embed, for example, a bearing 22 on the slide plate 23 to facilitate removal. In the above description, the upper seal flange 5 is used to support the weight by the slide plate 23, but this is not limited to the flange shape. It is also possible to provide the father part seal separately from the flange 5, instead of using it also as the flange 5. Again 7
It is also possible to provide two hinges 5 on the force transmitting member 14.

している。Apart from the method of using the slide plate 23 to take out the sample 9 as described above, it is also possible to consider a sample taking out device with a set of rotary levers as shown in FIG. 3.4, for example. In FIG. 3, a lever 31, a stopper screw 32, and a lever 33 are attached to the frame by a tube 34, and are rotated horizontally around the tube.

る。The tube 34 can be attached to the frame 15 by welding or screwing. In the structure shown in FIG. 3, a lever 31 and a lever 33 are connected by a stopper screw 32. The lever 33 is a pipe, and by inserting the lever 31 into the pipe, the length when assembled can be adjusted. This is because in the case of the structure shown in Figure 3, when attaching to the atmosphere cylinder 2, the tip of the lever cannot be placed under the upper seal 72 5 by simply moving the lever in the direction of rotation, so the combined length must be shortened. This is because it is necessary. On the other hand, in the one shown in FIG. 4, the tip of the lever can be placed under the upper seal flange simply by moving the lever in the rotational direction. The weight of the atmosphere cylinder 2, sample, etc. is controlled by lever 31.
It is supported by the tip of the tube 41, and the lever can be attached and moved rotationally around the tube 34 to take it out from the heating furnace.
上記の試料出し入れ装置を備える事によシ、試料の出し
入れを加熱炉を降温する事なく、又シール部を損傷する
おそれもなく行なう事ができる。By providing the above-mentioned sample loading/unloading device, samples can be loaded/unloaded without lowering the temperature of the heating furnace and without the risk of damaging the seal portion.
又これに必要な時間は、加熱炉の降昇温が不要であるこ

幅に短縮される。Furthermore, since there is no need to lower or raise the temperature of the heating furnace, the time required for this can be significantly shortened from about 2 days to about 3 hours.
