It has a pressure resistance of 7.5 Mpa (40 ° C.). The cylindrical portion 1 is rotated by turning the lid portion 2 around the rotation shaft 22, and the gas cylinder 7 is carried in and out.

  A guide support member 3 for guiding and supporting the gas cylinder 7 is placed inside the cylindrical portion 1. The configuration of the guide support member 3 will be described with reference to FIGS. 4 shows a perspective view of the guide support member 3, FIG. 5 shows a state in which the gas cylinder 7 is placed on the guide support member 3, and FIGS. 6 and 7 show the guide support member 3 on which the gas cylinder 7 is placed. It is the front view inserted in the shape part 1, and side sectional drawing. Reference numeral 72 in the figure denotes a protective cap installed in the gas cylinder 7 where gas has leaked. In this example, the position of the rear end of the guide support member 3 is regulated by the front surface of the weight 16, and the position of the step 12 at the front end of the cylindrical portion 1 and the rear end of the guide support member 3 are regulated. Since the distance from the restriction portion is larger than the length dimension of the guide support member 3, the guide support member 3 can slide back and forth on the inner peripheral surface of the cylindrical portion 1. In addition, the guide support member 3 can be taken out from the inside of the cylindrical portion 1 by lifting upward and pulling it out.

The guide support member 3 is made of a material that is resistant to corrosion, such as stainless steel, and has an outer shape that is generally along the lower half of the inner peripheral surface of the cylindrical portion 1 (half-cylindrical shape).
In the guide support member 3, curved members 33 curved in an arc shape are arranged along the inner peripheral surface of the cylindrical portion 1 at equal intervals along the length direction of the guide support member 3. Between the curved members 33, two rod-shaped rail members 31 and four plate-shaped members 32 are bridged along the inner surface. The two rail members 31 are extended in parallel to the bottom portion of the guide support member 3 via a gap. Two plate-like members 32 are extended in parallel on the left and right sides of the rail member 31. A donut-shaped flat plate is divided in half on the rear side of the guide support member 3, and the circumferential portion is guided by the guide support member 3. A stop plate 34 is provided so as to be in contact with the inner peripheral surface.

  The gas cylinder transport device of the present application is configured to be applicable to a plurality of types of gas cylinders having different lengths, and the stop plate 34 is for restricting the position of the bottom of the longest gas cylinder 7 among the plurality of types of gas cylinders. Is. In this example, the gas cylinder transporting device is configured to be applicable to a 25 kg gas cylinder as a first gas cylinder and a 5 kg gas cylinder as a second gas cylinder, and the 25 kg gas cylinder is provided with a stop plate 34. Therefore, the rear position is restricted. In the following description, the reference numerals 7a and 7b are assigned to the gas cylinder for 25 kg and the gas cylinder for 5 kg, respectively, and the reference numeral “7” is assigned as described above when the gas cylinder is not specified.

A member indicated by reference numeral “4” in FIG. 8 is a constituent member of the gas cylinder transporting device of the present invention. When the 5 kg gas cylinder 7b is stored in the cylindrical portion 1, the regulating member 4 The gas cylinder 7b is attached to the guide support member 3 at a position corresponding to the length dimension.
The restricting member 4 is composed of an arc-shaped member 43 having a plate-like body curved in an arc shape so as to follow the peripheral surface of the 25 kg gas cylinder 7. 42 extends. On the other hand, the locking plate 41 extends downward.

  As shown in FIG. 9, the arc-shaped member 43 is arranged so as to be bridged between the two rail members 31 provided on the guide support member 3, and the locking plate 41 is engaged with the front end portion of the bending member 33. It is stopped and rearward movement is restricted. Therefore, when the gas cylinder 7b for 5 kg is placed on the guide support member 3 and pushed inward, the position of the bottom of the gas cylinder 7b is regulated. That is, the regulating member 4 is detachably provided on the guide support member 3.

  A process for treating a gas cylinder in which gas has leaked using the above-described gas cylinder transporter will be described. When a gas leak occurs in the gas cylinder 7a, an attempt is first made to suppress the gas leak. In many cases, the gas leakage occurs at the valve portion of the gas cylinder 7. In the case of leakage from the valve part, a protective cap 72 is installed so as to close the valve part. After trying to suppress gas leakage, the gas cylinder transporter is moved to the position of the gas cylinder 7 and the wheel 62 is fixed by a wheel stopper, and then the lid 2 is rotated to be fully opened. The lid portion 2 is heavy due to its pressure resistance. The cylindrical portion 1 is arranged eccentrically on the carriage 6 and is configured to maintain the stability of the carriage 6 even when the lid portion 2 is fully opened. However, since the center of gravity moves greatly when the lid 2 is opened and closed, it is carefully opened and closed. After opening the lid 2, the surface of the flange 11 is cleaned.

  In the case of the gas cylinder 7a for 25kg, the gas cylinder 7a is placed horizontally, lifted by the transport belt, and the bottom edge of the two rail members provided on the guide support member 3 inside the cylindrical portion 1 31 is contacted. Next, the gas cylinder 7 a is pushed backward while being guided by the rail member 31, and is gradually placed on the guide support member 3, and the gas cylinder 7 a is pushed in until the bottom hits the stop plate 34. In this way, as shown in FIG. 4, the gas cylinder 7a is placed on the guide support member 3 in a posture in which the gas cylinder 7a is laid so that the protective cap 72 side faces the front side. The two rail members 31 of the guide support member 3 have a role of restricting rolling in order to support the gas cylinder 7 in contact therewith.

  Further, when storing a gas cylinder having a short length, for example, a gas cylinder 7b for 5 kg, the regulating member 4 is installed in accordance with the length of the gas cylinder to be stored. First, the guide support member 3 is pulled out from the tubular portion 1 by half while lifting upward. The regulating member 4 is locked to the front end side of the third bending member 33 provided on the guide support member 3, for example, from the front side.

  Similarly to the 25 kg gas cylinder 7a described above, the gas cylinder 7b is laid down so that the bottom portion is on the rear side, and is placed on the front side of the regulating member 4. The gas cylinder 7b is placed on the guide support member 3 so that the bottom of the gas cylinder 7b comes into contact with the regulation plate 42, and the movement to the rear side is regulated. After the gas cylinder 7b is placed on the guide support member 3, as shown in FIGS. 10 and 11, the body and neck of the gas cylinder 7b are fixed by the belt 5 as a fixing tool. The belt 5 for fixing the body portion fixes the gas cylinder 7b to the lower two of the plate-like members 32. On the other hand, after the belt 5 for fixing the neck is wound around the neck, the belt 5 is routed below the gas cylinder 7b and hooked on the rear side of the curved member 33 of the rail member 31 to move the gas cylinder 7b forward. regulate. The gas cylinder 7 b is inserted into the cylindrical portion 1 together with the guide support member 3 after being placed on the guide support member 3. The guide support member 3 is inserted until it hits the front surface of the weight 16, and the front end is hooked on the step 12, so that the back and forth movement is restricted.

  Subsequently, the lid 2 is closed. The lid 2 is turned around the vertical axis about the rotation shaft 22 and moved to a position facing the flange 11. The lid 2 and the flange 11 are arranged with a gap of about 10 mm after the position is adjusted by the guide pin 23. After the gasket 29 is inserted into the gap, the lid 2 and the flange 11 are fixed so that the stopper 24 is inserted into the bolt holes 26 and 27 and a force is evenly applied to the peripheral edge. After fixing the lid portion 2, the presence or absence of gas leakage from the cylindrical portion 1 is confirmed by the value of the pressure gauge 15 or the foaming liquid. After confirming that there is no gas leakage, the gas cylinder transporter is moved to the manufacturer or an appropriate processing facility.

  In the gas cylinder transport device transported to the processing facility, the gas discharge valve 14 is connected to the gas processing device of the processing facility while the lid 2 is closed, and the toxic gas filled inside is discharged. After the internal pressure is reduced, the cylindrical portion 1 is opened by opening the air introduction valve 13. While the concentration of the toxic gas inside the cylindrical portion 1 is gradually lowered by the atmosphere, the toxic gas is sucked from the gas discharge valve 14 side by the vacuum pump and introduced into the gas processing apparatus to be processed.

  The gas cylinder 7 is unloaded from the cylindrical portion 1 after the gas processing is completed. In the case of the gas cylinder 7a, the lid 2 is rotated and opened, and then the gas cylinder 7a is pulled out. At this time, the guide support member 3 is also applied with a force in a direction in which the guide support member 3 is pulled out together with the gas cylinder 7a because of the frictional force due to the weight of the gas cylinder 7a. The guide support member 3 remains in the cylindrical portion 1 because the forward movement is restricted by the step 12 provided in the cylindrical portion 1. Therefore, the gas cylinder 7 a can be slid out on the rail member 31 provided on the guide support member 3.

  On the other hand, when carrying out the 5 kg gas cylinder 7b, the guide support member 3 and the 5 kg gas cylinder 7b fixed to the guide support member 3 are both lifted upward and pulled out. After the guide support member 3 is pulled out about half, the 5 kg gas cylinder 7 b is taken up from the guide support member 3 with the belt 5 fixing the neck and the peripheral body part removed.

  In the embodiment of the present invention, two types of gas cylinders 7 are used as an example. However, even when the gas cylinders 7 are used in three or more types, the restriction member 4 on the guide support member 3 is also changed according to the length of the gas cylinders 7. It can be applied by changing the installation position. The installation position of the regulating member 4 on the guide support member 3 can be changed depending on the installation interval and the number of the bending members 33 on the guide support member 3 and can be applied to gas cylinders 7 of various sizes.

  According to the above-described gas cylinder transporting device, the gas cylinder 7 is guided in the length direction of the cylindrical portion 1 by the guide support member 3 in the cylindrical portion 1, so that it is easy to carry in and out. Further, by providing the guide support member 3 with the restricting member 4 so as to be detachable, when the first gas cylinder 7a having a large length is carried into the cylindrical portion 1, the restricting member 4 is removed and the first gas cylinder 7a having a small length is removed. When the second gas cylinder 7 b is carried into the cylindrical portion 1, a plurality of types of gas cylinders 7 having different length dimensions can be carried into the cylindrical portion 1 by mounting the restriction member 4 on the guide support member 3. And since the gas cylinder 7b with a short length dimension is controlled by the area | region close | similar to a carrying-in / out opening without entering into the back | inner part of the cylindrical part 1, the carrying-out of the gas cylinder 7b is easy.
