DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for storing a probe for sampling a molten material in a melting furnace such as a radioactive waste melting furnace so that it can be appropriately extracted at an unused stage. .

[0002]

2. Description of the Related Art Conventionally, as a means for sampling a melt in a metal melting furnace in an iron making plant or the like, Japanese Patent Publication No.
Japanese Patent Application Laid-Open No. -66615 is known. In this apparatus, a plurality of sampling probes having a cup for collecting the melt are used, and these probes are picked up one by one and immersed in the melt in the melting furnace. . Since the molten portion is taken into the probe by this immersion, sampling of the molten portion can be performed by pulling up the probe from the metal melting furnace.

By the way, in order to efficiently perform the above-described sampling, it is preferable to install a storage case for storing a plurality of unused probes in a standing state in advance. One example is shown in FIG. In the figure, a probe storage case 200 is installed on the ground so as to open upward, and a plurality of probes 202 are stored in the probe storage case 200 in an upright state. Specifically, a plurality of cylindrical guides 2
No. 03 is provided, and each probe 202 is inserted into the inside thereof, so that the probe 202 is held in an upright state.

Each probe 202 has a cylindrical shape, a lower end portion of which is provided with a temperature sensing portion 204 for detecting a temperature of a melt, and an upper end portion 206 of the probe 202 has a holder 20.
8 is press-fittable. The holder 208 has a contact portion 210 on a side surface thereof, and an upper end portion is held by a transfer robot or the like (not shown). When the holder 208 is pressed into the upper end portion 206 of the probe 202 stored in the probe storage case 200 from above, the holder 208 and the temperature sensing portion 25 are electrically connected to each other through the contact portion 210. And the holder 208 and the probe 202 are coupled by frictional force. In this state, the probe 202 can be lifted up from the probe storage case 200 integrally with the holder 208.

[0005]

SUMMARY OF THE INVENTION The holder 208 includes:
Operating near the melting furnace, the hot probe 202
, And is likely to be warped by thermal deformation (see a two-dot chain line in FIG. 12). Even if the holder 208 is simply lowered in the vertical direction while the holder 208 is in the warped state, the holder 208 is moved to the upper end 2 of the probe 202.
06 may not be press-fitted, and even if press-fitted, there is a disadvantage that an eccentric load acts on the probe 202 by the amount of the deformation.

In order to avoid such inconvenience, the holder 208 may be lowered while moving it in the horizontal direction as appropriate in accordance with the warped shape. However, in order to make the holder 208 perform such a complicated movement, However, the control contents of a transfer robot or the like that operates the holder 208 also become very complicated, and the cost cannot be avoided.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a storage device for a sampling probe capable of smoothly pressing a holder into an upper end portion of the probe and removing the holder with a simple and inexpensive configuration. I do.

[0008]

As a means for solving the above-mentioned problems, the present invention relates to a method in which a holder is inserted into a melting furnace while being integrally transferred with the holder in a state where the holder is inserted at an upper end. In a storage device for a sampling probe for storing unused sampling probes in an upright state so that they can be extracted from above, a probe storage device which is opened upward and through which the probe is inserted and withdrawn. A case and case support means for supporting the probe storage case so as to be displaceable in at least one horizontal direction, wherein the probe storage case is held at a fixed reference position in a state where no external force is applied to the probe storage case. It is configured as follows.

According to this configuration, even when the holder is deformed due to the influence of heat or the like, if the holder is lowered from directly above the probe in the housed state, the probe can be changed according to the deformed shape of the holder. Since it is horizontally displaced integrally with the probe storage case, the holder can be inserted into the probe.

Here, when the probe storage case can be displaced only in one horizontal direction, the holder is turned down in advance so that the warp direction matches the displaceable direction, and then the holder is lowered. Can be inserted.
On the other hand, if the case support means is configured to support the probe storage case so as to be displaceable in an arbitrary horizontal direction, a rotation operation or the like on the holder side becomes unnecessary, and the holder is simply lowered. You can insert it.

More specifically, the means for supporting the probe storage case includes a case support portion disposed above the probe storage case, and a vertically extending portion between the case support portion and the probe storage case. A plurality of link members to be connected may be provided, and the probe storage case may be suspended and supported by the case supporting portion via these link members so as to be displaceable in the horizontal direction. According to this configuration, due to the weight of the probe storage case, the case is automatically held at the reference position without receiving any external force.

Further, in this device, the probe housing can be moved in any horizontal direction by connecting the upper end and the lower end of the link member to the probe housing and the case supporting member via universal joints. can do.

In each of the above apparatuses, a support state in which the probe housed in the probe storage case is supported from the radial outside and a separation state in which the probe is radially separated from the probe near the opening of the probe storage case. By providing the probe supporting means which can be switched to the above, the operation of inserting the holder into the probe can be made smoother. That is, in this apparatus, the probe can be inserted into the probe storage case by switching the probe support means to the separated state, while the probe is supported when the probe is removed, that is, when the holder is inserted into the probe. By switching the means to the support state and supporting the probe from the outside in the radial direction, the probe can be prevented from wobbling when the holder is inserted, and the holder can be more reliably inserted.

Further, if an engaging portion for engaging with the lower end of the probe is provided at the bottom of the probe housing case and an elastic body is interposed between the engaging portion and the bottom surface of the probe housing case, When the holder is inserted into the probe in a state where the engagement portion and the lower end of the probe are engaged, the insertion force is absorbed by the elastic deformation of the elastic body, and a large load acts on the probe to prevent damage to the probe. This is prevented from occurring.

The ends of the link bars 47 and 48 on the side closer to the air cylinder 44 (the right side in FIGS. 3 and 4) are connected to a common connecting plate 52 extending forward and backward. The connecting plate 52 and all the link bars 47 and 48 are integrally moved in the left and right direction by the expansion and contraction of the telescopic rod 44a, whereby each lever 39 is rotated and driven.
Each probe support claw 42 is opened and closed.

The probe storage device 16 is for storing the probe 12 lifted from the melting furnace 10. Details of the structure are shown in FIGS.

The distal end of a telescopic rod of each air cylinder 130 is connected to both ends of each shutter 12 through a link 136 arranged in a V-shape, and each shutter 12 is simultaneously opened and closed by the telescopic operation of the air cylinder 130. It has become.

Further, on the top wall 141 of the outer case 100, there is provided a probe holding device 140 for holding the upper end of the probe 12 just before being housed. Specifically, an air cylinder 142 is fixed on the top wall 141, and a pair of upper and lower central gripping plates 144 is fixed to a telescopic rod of the air cylinder 142, from both left and right end surfaces of the central gripping plate 144.

One end of each link 156 is rotatably connected to the central gripping plate 148 via a pin 158, and the other end is both ends of the frame-shaped gripping plate 148 via a pin 160. Are connected so as to be relatively rotatable. The two links 156 swing with the expansion and contraction operation of the air cylinder 142, and the central gripping plate 144 and the frame-shaped gripping plate 148 connected to the links 156 slide in directions opposite to each other. , Each probe grip 146 and the probe grip 149 are the probe 1
Holding state of holding the upper end of 2 (state shown by solid line in FIG. 8)
And a release state in which the probe gripper 146 and the probe gripper 149 release the upper end of the probe 12 (a state shown by a two-dot chain line in the same figure).

This probe handling device is equipped with a control device 90 as shown in FIG. This control device 9
0 receives the detection signal input via the holder 33 and the air cylinders 44, 130, 14
The control signal is output to the air control valve and the transfer device 18 corresponding to 2 to control the operation thereof.

Next, the operation of the entire handling apparatus under the control of the controller 90 will be described with reference to the flowchart of FIG.

First, the holder 33 is held by the transfer device 18 (step S1), and on the probe storage device 14 side, each probe support claw 42 is switched to the closed position, thereby being stored in the probe storage device 14. The upper end of the unused probe 12 is supported from the outside in the radial direction (Step S2).

Next, the holder 33 is positioned at a position above the probe 12 to be taken out by the operation of the transfer device 18, and the holder 33 is lowered while being held by the transfer device 18. When the press-fitting position is reached, the descent is stopped (step S3).

At this time, the holder 33 is deformed due to thermal deformation as shown in FIG.
In the case of warping as shown by the two-dot chain line, in the conventional storage device, it is not possible to press-fit well only by lowering the holder 33 directly below, and even if press-fitting is performed, a large eccentric load may act on the probe 12. However, in the storage device of this embodiment, the probe storage case 22 for storing the probe 12 is suspended and supported by the fixed-side support case 20 so as to be displaceable in the horizontal direction.
The whole of the probe storage case 22 is appropriately horizontally moved in accordance with the warp shape of the holder 3, so that the holder 33 can be smoothly pressed. Therefore, no complicated control is required on the side of the transfer device 18, and the probe 12 has a simple and low-cost configuration.
The holder 33 and the probe 12 can be satisfactorily connected without applying a large load to the probe 33.

At the time of this press-fitting, a relatively large downward load is applied to the probe 12, but the temperature sensing portion 25 at the lower end of the probe 12 is fitted into the fitting tube 30, and Since the coil spring 32 for cushion is interposed between the case 12 and the case bottom wall 22a, the load is prevented from being directly applied to the main body of the probe 12 and the temperature sensing part 25, and these protections are appropriately performed. Done.

Moreover, in this apparatus, the probe support claws 4
By supporting the upper end of the probe 12 from the outside in the radial direction at the time of press-fitting the holder by the method 2, there is an advantage that the press-fitting of the holder 33 can be performed in a more stable state.

The press-fitting of the holder 33 causes the holder 33
And the temperature sensing part 25 should be electrically connected via the connector, but if the connection is not confirmed at this point (for example, if the level change of the pull-up voltage is not recognized) (at step S4) NO), the operation is stopped, a warning is issued to the outside, and the confirmation of the failure is prompted (step S5).

When conduction is confirmed (step S4)
YES), the probe support pawl 42 is switched to the open position shown by the two-dot chain line in FIG. 4, and then the holder 33 is pulled up (step S6). At this time, the probe 12 into which the holder 33 is press-fitted also rises integrally, and the probe 12 is picked up from the probe storage case 22.

The probe 12 is transported together with the holder 33 to a position above the melting furnace 10, and is lowered from this position, so that it is immersed in the melting part in the melting furnace 10. Thus, the temperature of the melt is measured, and the melt flows into the coagulation chamber in the probe 12 and is sampled (step S7).

When a predetermined time has elapsed after the start of immersion (YES in step S8). The probe 12 is lifted from the melting furnace 10 and transported above the probe storage device 16. In the storage device 16, the shutter 126 is switched to the open position indicated by the two-dot chain line in FIG. 5, and the probe gripping device 140 is switched to the release state indicated by the solid line in FIG. Probe 1
2 is inserted (step S9). The lowering of the probe 12 is stopped before the temperature sensing part 25 of the probe 12 lands, and the probe gripping device 140 is switched to the gripping state (the state shown by the two-dot chain line in FIG. 8).
Is held by both probe holding units 146 and 149 (step S10). By raising the holder 33 in this state (step S11), the holder 33 is removed from the probe 12. After the removal, the probe 12 is completely dropped into the sealed chamber by releasing the gripping by the probe gripping portions 146 and 149 (step S12).

By repeating the above operation for each probe 12, the sampled probes 12 are sequentially sealed one by one in the sealed chamber of the probe storage device 16. Thereafter, after the sampling operation by all the probes 12 is completed, the inner case 104 is moved to the outer case 100.
, All the probes 12 can be collectively collected.

In the above embodiment, the probe storage case 22 can be moved in an arbitrary horizontal direction. However, the present invention is applicable to the case where the probe storage case 22 can be displaced only in one horizontal direction. And excellent effects can be obtained. For example, the link rod 26 and the top wall 20c of the support case 20 and the bottom wall 22a of the probe storage case 20 are rotatably connected by simple pins instead of the universal joints 24A and 24B, so that a horizontal line perpendicular to the pins is provided. The probe housing case 22 may be displaced only in the direction. In this structure, when the warping direction of the holder 33 is different from the displaceable direction of the probe housing case 22, the holder 33 may be rotated until both directions match, and then the insertion operation may be performed. However, if the probe storage case 22 is configured to be displaceable in any horizontal direction as in the above-described embodiment, it is not necessary to rotate the holder 33, and the insertion can be performed by a simple operation of simply lowering. There are advantages.

In the above embodiment, the supporting case 20
Has been shown to suspend the probe storage case 22, but, for example, a large number of balls are spread and the probe storage case 22 is placed thereon, or a rollable caster is provided on the lower surface of the probe storage case 22. After
Even if a holding means (for example, a spring or the like) for holding the probe housing case 22 at a predetermined reference position without receiving an external force is provided, smooth insertion of the holder 33 can be realized. However, if the probe storage case 22 is floated by the suspension support as described above, the moving resistance of the probe storage case 22 can be significantly reduced, and the probe storage case 22 is automatically weighed by its own weight. There is an advantage that the storage case 22 can be held at a predetermined reference position.

[0057]

As described above, according to the present invention, the probe storage case which opens upward is supported so as to be displaceable in at least one horizontal direction, and the probe storage case is kept constant in a state where no external force is applied to the probe storage case. A large eccentric load is applied to the probe by a simple operation of lowering the holder even if the holder is deformed due to heat or the like, since the holder is held at the reference position. Without this, there is an effect that the probe can be taken out by smoothly inserting the holder into the probe.

In particular, if the case support means is configured to support the probe storage case so as to be displaceable in an arbitrary horizontal direction, the insertion can be performed only by lowering the holder regardless of the deformation direction of the holder. Therefore, an operation of rotating the holder in advance is not required, and an effect that the operation of the holder can be simplified can be obtained.

More specifically, the apparatus includes a case supporting portion disposed above the probe housing case, and a plurality of link members for vertically connecting the case supporting portion and the probe housing case. According to the configuration in which the probe storage case is suspended and supported so as to be displaceable in the horizontal direction by the case support portion via the link member, the displacement resistance of the probe storage case in the horizontal direction can be significantly reduced. Moreover, in a state where no external force acts on the probe storage case, an effect is obtained that the case can be automatically held at the reference position by utilizing the own weight of the probe storage case.

Further, by connecting the upper end and the lower end of the link member to the probe storage case and the case supporting member via universal joints, respectively, the probe storage case can be moved in any horizontal direction. .

In each of the above apparatuses, a support state in which the probe housed in the probe storage case is supported from the outside in the radial direction and a separation state in which the probe is radially separated from the probe near the opening of the probe storage case. By providing the probe supporting means which can be switched to the above, an effect that the operation of inserting the holder into the probe can be made smoother can be obtained.

Further, if an engaging portion for engaging with the lower end of the probe is provided at the bottom of the probe housing case and an elastic body is interposed between the engaging portion and the bottom surface of the probe housing case, By inserting the holder into the probe in a state where the engaging portion and the lower end of the probe are engaged with each other, the insertion force is absorbed by the elastic deformation of the elastic body, and the effect of preventing damage to the probe can be obtained. Can be
