In general, steel mills take samples of the molten iron produced in the blast furnace, transfer them to an analysis chamber located at a remote location, and perform component analysis.

In this way, the component analysis is carried out to determine the operation details in the furnace according to the components of the molten iron, to change the proper operation pattern, and to improve the quality of the molten iron by adding an artificial component regulator.

Therefore, rapid charter analysis is a very important technical factor in terms of charter quality control.

A related molten iron sample transfer device is shown in FIG. The molten iron sample transfer device 100 is a place to send the transporter 110, the molten iron sample is contained, and the molten iron sample transfer device 100 of the same structure is installed in each place receiving the transporter 110, the carrier ( 110, each of these molten iron sample transfer device 100 is provided with a space 112 in which the transporter 110 is located therein and a door 114 for closing it, the air inside the space 112 It is equipped with a limit switch 116 for detecting whether the transmitter 110 is located, and if the transmitter 110 is located in the space 112, the pneumatic cylinder for pushing it up to the compressed air injection chamber 120 side of the upper side Equipped with 122.

In addition, the compressed air injection chamber 120 is provided with a compressed air engine 126 for pushing the rear side of the carrier 110 at an air injection pressure of approximately 2.5 kg / cm 2.

However, the conventional molten iron sample transfer device 100 as described above is moving the transporter 110 at the air injection pressure, but such a conventional device 100, the arrival of the transporter 110, the transporter 110 It is a problem that the pneumatic cylinder 122 is frequently broken by not absorbing the impact force applied properly. And the damage of these mechanical parts is introduced into the transfer path 128 of the transporter (110) to prevent the smooth movement of the transporter 120 to prevent the rapid transfer of the molten iron sample, the molten iron sample Interfering with the rapid analysis of the components of the molten iron causes a decrease in the molten iron quality.

In the cylinder tube 10, the shock absorbing portion 20 that effectively absorbs the impact force of the carrier, and the air that is fitted to the outside of the cylinder tube 10 to pressurize the inside of the cylinder tube 10 so as not to leak to the outside The cylinder gate 30 is provided.

The cylinder tube 10 has one end coupled to the conduit 12 having the compressed air supply port 12a as the flanges 14a and 14b and the bolt 15, and the other end to the carrier entrance conduit 16. Is connected to the flange 17a, 17b and the bolt 18, the outer surface is formed with a cutting hole 19 that can be moved in and out of the carrier 110.

In addition, the cylinder tube 10 has a cylindrical structure so that the air provided from the compressed air supply port 12a may flow into the conduit entrance conduit 16.

In addition, the shock absorbing portion 20 is provided with a guide stopper 21 formed in an arcuate shape on the inner side of the cylinder tube 10, biased toward the compressed air supply port 12a in the cylinder tube 10, The spring guide 22 is fitted into the center hole 21a of the guide stopper 21. The spring guide 22 has a hollow structure, and a male screw portion 22a is formed at one side thereof, and at the other end thereof. An enlarged diameter circular step 22b is formed that matches the inner diameter of the cylinder tube 10. Therefore, a long circular hole 22c is formed in the center of the spring guide 22. On the other hand, the male screw portion 22a of the spring guide 22 is provided with a guide nut 24 screwed on the other side of the guide stopper 21, so that the guide stopper 21 has a guide nut 24 and a spring guide ( It is fitted in the annular space (26) between the 22, and at the same time a plurality of disc springs 27 are inserted between the guide stopper 21 and the spring guide 22 in the annular space (26).

The plurality of disc springs 27 has a disc-shaped body 28 formed with a hole 28a into which each spring guide 22 is fitted, as shown in detail in FIG. The outer circumferential edges of the body 28 form inclined surfaces 29 that are bent to one side, respectively, and a plurality of pairs thereof are disposed to face each other in pairs.

In addition, the cylinder gate 30 is fitted to the outside of the cylinder tube 10, the cylinder gate 30 has a cylindrical body 32 structure, the body 32 than the cutting hole 19 It has a long length, the diameter portion 34 that the flange portion 14a, 14b connected to the conduit 12 of the compressed air supply port 12a at one end of the body portion 32 can be fitted therein 34 ) Is formed, and a sealing portion 36 in which the packing 36a is fitted by a plurality of bolts 37 is formed between the cylinder tube 10 and the other end.
