Additionally, a proximity switch (not shown) that limits the forward and backward movement length of the floor 20 can be installed to allow the floor 20 to move between a predetermined front limit point and a rear limit point.

The chamber door and floor moving device of the present invention configured as described above operates as follows.

When placing a high load or large sample into the chamber, the door 10 is first opened. When the drive motor 12 is operated, power is generated in both directions to rotate the transmission shaft 13, and this rotational force is generated by the bevel gear device 14. ) is converted by 90 degrees to rotate the vertically installed screw shaft (15). When the screw 15 rotates, the lifting platform 15a rises by the screw connection relationship.

When the lifting platform (15a) rises, the connection bar (17), guide roller (18b), door (10), and guard (18) connected to it rise together.

At this time, the action of the roller 17a installed on the inside of the connecting base 17 and the rail 17b installed in the vertical direction on the lifting guide 16, and the roller 15b installed at the rear of the lifting base 15a and the installation base 11 ), the elevating platform 15, connecting bar 17, guide roller 18b, door 10, and guard 18 maintain stability and rise due to the action of the rail 15c installed in the vertical direction on the column.

Since the long hole 17c forming the Afterwards, it rises along the vertical guide slot (16a).

Therefore, friction does not occur between the rear of the door 10 and the front of the main body 1, and the lifting and lowering action becomes smooth. Generally, packing is constructed between the rear of the door 10 and the front of the main body 1 to maintain airtightness. During the lifting and lowering process of the door 10, there is friction or friction between the rear of the door 10 and the front of the main body 1. No contact occurs and these packing parts are not damaged.

As described above, with the door 10 raised, the floor operating device is operated to pull the floor 20 forward. For this purpose, when the drive motor 25 is operated, rotational force is generated, and this rotational force is applied to the screw shaft 28 through the transmission shaft 26 and the bevel gear device 27.

When the screw shaft 28 rotates, the floor 20 moves forward along the rail 24 and is pulled out due to a screw engagement relationship with the female thread forming body 28a coupled to the floor 20.

The front support wheel 21 installed in front of the floor 20 is in contact with the ground and exposed to the outside, so there is no need to install a separate rail on the ground.

In this way, a sample is placed on the floor 20 in a state in which the floor 20 is pulled forward. At this time, samples can be placed in front and on both sides of the floor 20 depending on the site situation. Samples can be placed in a variety of ways, including a forklift as well as a hoist.

After placing the sample on the floor 20 pulled out to the outside, the floor 20 is brought into the main body 1. To this end, the drive motor 25 is rotated in the opposite direction to rotate the screw shaft 28 in the opposite direction, Then, the floor 20 moves backward along the rail 24 and returns to the inside of the main body due to the screw engagement relationship with the female thread forming body 28a fixed to the floor 20.

Then, the door 10 is lowered. For this purpose, when the drive motor 12 is rotated in the opposite direction, the vertical screw shaft 15 rotates in the opposite direction and the elevator platform 15a is moved by the screw connection relationship with the elevator platform 15a, which can be moved in the vertical direction. descends downward.

When the lifting platform (15a) is lowered, the connection bar (17), guide roller (18b), guard (18), and door (10) connected to it are lowered. The guide roller (18b) descends in the vertical direction along the guide slot (16a) of the lifting guide (16) and then moves backward along the roll slot (16b) at the lower end and lowers to close the door (10).

Therefore, the door 10 descends smoothly without friction or contact with the front of the main body 1 and does not cause damage to the packing.

The above-mentioned moving device can be operated by an automated system, in which case the operator can perform the door raising and floor withdrawal operations or the floor return and door lowering operations by pressing just one button.

In this way, the door and floor moving device of the chamber of the present invention draws the floor out of the chamber to test a high load or large sample, places the sample on the floor in an atmosphere without any hindrance to sample movement, and then moves the floor and the sample together. Since it can be inserted into the chamber, the sample can be easily and stably placed in the chamber, and the sample installation work time is also greatly shortened.
