Description

TECHNICAL FIELD [0001] The present invention relates to a nozzle test apparatus and a nozzle test apparatus. [0002] The present invention relates to a nozzle test apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a test apparatus for a nozzle and a nozzle count measurement sensor, and more particularly, to an apparatus for testing a state of a spray piping nozzle of a segment used in a performance process.

Generally, the slab of the continuous casting process is firstly cooled in the mold itself, and then the surface is drawn into the segment with the surface coagulated to some extent.

Fig. 1 schematically shows the construction of the segments, in which the upper frame 1, the lower frame 2 and the adjustment cylinder 3 for adjusting the nozzles are connected at the upper and lower sides .

That is, the segment includes a nozzle 5 for spraying cooling water 8 on the surface of the slab so as to cool the slab whose surface has been solidified to some extent through primary cooling in the mold, See FIG.

Further, regarding the above-mentioned conventional segment and spray piping nozzle, refer to Korean Patent Laid-Open Publication No. 2009-0010999 (2009.01.30) (Patent Document 1).

Here, the nozzle 5 injects cooling water between the guide rolls 4 provided on the upper and lower sides, and the gap can be adjusted by the adjusting cylinder 3.

Incidentally, in the construction of the segment as described above, the number and spacing of the guide rolls 4, the specifications of the nozzles, the specifications of the regulating cylinders, and the like may be different for each segment.

In addition, the nozzle 5 mounted on the segment and spraying the cooling water onto the slab surface is removed from the segment and subjected to separate repair and maintenance work during repair work of the segment at the repair shop.

At this time, when the repair of the nozzle 5 is completed, the nozzle 5 is mounted on the segment again, and a predetermined nozzle test process is performed before the actual process is input. 2, the measurement frame 6 is provided, and the measurement pad 6 is provided on the measurement frame 6 to allow the nozzle 5 to contact the cooling water. As shown in FIG. 2, , And the measurement sensor mounted on the measurement pad 6 confirms the quantity of the nozzle.

However, since there is no separate test apparatus due to different specifications and nozzle sizes in the process of measuring the nozzle water quantity as described above, in order to test the nozzles 5 that have been repaired, After measuring the quantity of water through the measurement sensor, it was necessary to repeat the operation of removing and mounting the nozzle until the normal value was obtained through the measurement sensor.

Such mounting and unscrewing operations of the nozzles have to be repeated until the quantity of the nozzles exhibits a good value. In addition, if the nozzle 5 is not accurately tested, the nodal angle of the nozzles in the actual process may be poor, Damage or interference, which directly affects quality defects.

In addition, since there is no separate testing device, workers who had to repeat nozzle mounting and unloading operations from the segment had to invest more time than necessary, and repeated work required the cost of physical damage and additional work did.

In such a nozzle test operation, repeated nozzle mounting and wiping operations cause fatigue of a worker, resulting in reduced work concentration and efficiency, and it is difficult to expect an accurate test result of the nozzle.

And, if the nozzles that have not undergone precise testing are mounted on the segment and put into the actual process, the non-water ability of the unproven nozzle directly affects the casting quality.

Therefore, although the repair work after the repair and the repair of the nozzle are very important factors in the casting process to improve the quality of the product and improve the productivity, there is no proper nozzle test device, And it was forced to repeatedly work out the nozzle and test the repair status of the nozzle.

Further, in order to clarify the gist of the present invention, a description of elements and techniques well known in the prior art will be omitted, and a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

However, the technical features of the present invention are not limited by the embodiments to which the present invention is applied or explained in the following embodiments, and various modifications are possible within the technical scope of the present invention.

Hereinafter, a detailed configuration of a nozzle nozzle rain rate sensor test apparatus according to the present invention will be described with reference to FIGS. 1 to 7B.

3 is a perspective view showing a schematic configuration of a nozzle and nozzle rate sensor test apparatus. FIG. 4 is a front view, and FIGS. 5A and 5B are a left side view.

3, the apparatus for testing the nozzle and nozzle count sensor according to the present invention comprises a device frame 10, a supply unit 20, a guide roll 30, and a rotation guide unit 40 (50). ≪ / RTI >

The apparatus frame 10 is configured as shown in Fig. 3, and may be fixed to the floor surface through a coupling means such as a bolt. However, it is revealed that the shape, material, and whether the apparatus frame is fixed to the bottom surface can be modified at any time depending on the use environment.

The supply part 20 may be provided on one side of the upper part of the apparatus frame to mount a nozzle 5 for spraying cooling water and air. The nozzle 5 is a Segment Spray Piping Nozzle used in a steelworks performance repairing process and is used for spraying cooling water on the surface of a slab in a casting process.

At this time, the nozzle (5) is removed from the repair workshop at the repair workshop, and after maintenance work is completed through a certain repair process, the nozzle (5) is attached to the plant and used again. Prior to mounting the repair and maintenance nozzle (5) on the equipment, it is necessary to check the spray nodal angle and the quantity of water beforehand to prevent defective product due to defective nozzle angle error and clogging, It is possible to use the present nozzle and the nozzle non-flow rate measuring sensor test apparatus.

Accordingly, the supply unit 20 is provided so as to mount the nozzle 5 in a state in which the repair and maintenance work are completed in the segment. The nozzle 5 mounted on the supply part 20 may be connected to the cooling water and the air supply means so as to form an environment in which the cooling water is sprayed as in the actual segment, have.

At this time, the reason why the cooling water and the air are supplied together is that the cooling water is injected by using the high pressure. It is obvious to a person skilled in the art that the cooling water is sprayed by the cooling water so as to be effective for cooling the slab.

The supply unit 20 includes a plurality of supply lines 21a and 21b fixed to the upper portion of the apparatus frame 10 so as to be disposed above the plurality of guide rolls 30 to supply cooling water and air . The supply line 21a may be configured to supply cooling water and the other supply line 21b may supply air to the supply lines 21a and 21b, To the nozzle (5) so that cooling water and air passing through the nozzle (5) are supplied to the nozzle (5).

At this time, the supply line 21a, b may be connected to the nozzle 5, and the nozzle mounting unit 22 may be provided in the supply part to fix the nozzle.

As shown in FIG. 4, the nozzle mounting unit 22 includes a mounting beam 23 to which both ends are fixed to the apparatus frame 10. One end of the mounting beam 23 is fixed to one side of the apparatus frame 10 and extends in the longitudinal direction of the guide roll 30 and the other end is fixed to the other side of the apparatus frame 10.

At this time, the mounting beam 23 is installed to move a certain distance in the height direction of the apparatus frame 10, so that the fixing height of the nozzle can be adjusted on the apparatus frame 10 according to the specifications of various nozzles 5 .

That is, grooves 25 are formed on both sides of the apparatus frame 10 in the longitudinal direction of the apparatus frame. A plurality of bolts 26 passing through the mounting beams 23 are inserted into the grooves 25 to fix the mounting beams 23 on the apparatus frame 10.

Accordingly, the user can move the mounting beam 23 for a certain period in the groove 25, and after placing the mounting beam at a proper position according to the length of the nozzle, a plurality of bolts 25 are coupled to the groove So that the mounting beam 23 can be fixed to the apparatus frame 10.

A plurality of manifolds 24 are provided in the longitudinal direction of the mounting beam 23, and one end of the nozzle may be fixed to the manifold 24. That is, the manifold 24 supplies the cooling water and the air from the supply lines 21a and 21b to the nozzle 5 so that the nozzle 5 can inject the cooling water.

Therefore, as shown in FIGS. 5A and 5B, the manifold 24 can be connected to the supply lines 21a and 21b by a flexible hose 27. The flexible hose 27 having a bendable characteristic will be useful in the use environment of the apparatus.

The number of the manifolds 24 installed in the longitudinal direction of the mounting beam 23 becomes equal to the number of the nozzles 5 since one nozzle 5 can be fixed to one manifold 24.

The manifold 24 is provided so as to be movable in the longitudinal direction of the mounting beam 23 so that the spacing between the nozzles 5 can be adjusted when a plurality of nozzles 5 are installed.

Therefore, the spacing grooves 25 are formed in the longitudinal direction of the mounting beams 23 and the end portions of the plurality of bolts 25 passing through the manifold 24 can be coupled to the grooves 25 . This allows the user to move the manifold 24 in the groove 25 as necessary and to secure the manifold 24 to the mounting beam 23 by engaging the bolt 25 at the desired position . In this manner, the flexible hose 27 can also be usefully used for the movement of the manifold 24 as well.

One end of the nozzle 5 is contacted and fixed to the nozzle mounting unit 22 constructed as described above. When the mounting beam 23 is moved on the apparatus frame 10, the height of the nozzle can be adjusted, The distance between the nozzles can be adjusted by moving the nozzle 24 on the mounting beam 23. [

A plurality of guide rolls 30 may be installed under the nozzle of the nozzle 5. The guide roll 30 has the same structure as the guide roll 30 mounted on a segment and is a constitution for creating a segment environment in an actual casting process for an effective nozzle 5 test.

5A and 5B, the guide roll 30 is arranged at the lower portion of the nozzle 5 in the actual casting step. Therefore, the guide roll 30 in the present apparatus also , And may be fixedly installed on the apparatus frame 10 so as to be disposed below the nozzle opening of the nozzle 5.

Therefore, the cooling water injected from the nozzle 5 falls down to be brought into contact with the surface of the guide roll 30, and will pass through the guide roll 30. However, in accordance with the specifications of the respective segments, the intervals between the guide rolls may be differently provided. Therefore, in this apparatus, the guide rolls 30 are provided so as to be adjustable in mutual spacing.

Although the method for installing the guide roll 30 in the apparatus frame 10 may be various as described above, the present invention provides an example for effectively fixing the guide roll 30 to the apparatus frame 10 .

3, the apparatus frame 10 includes a plurality of first bracket members (not shown) disposed at both ends of the guide roll 30 and spaced apart from a side surface of the guide roll 30 And a plurality of second bracket members 13 connected to both ends of the guide roll 20 and disposed at positions corresponding to the first bracket members 12, respectively.

As shown in FIGS. 5A and 5B, the second bracket member 13 is connected to the second bracket member 13 through the first bracket member 12, and the second bracket member 13 is moved And a plurality of screw shafts 14 for adjusting the distance of the guide rolls 30.

Therefore, a thread groove corresponding to the thread of the screw shaft 14 should be machined inside the first bracket member 12 and the second bracket member 13 through which the screw shaft 14 passes.

In order to facilitate the rotation of the screw shaft 14, when a lever of a certain standard is connected to the end of the screw shaft 14 located on the first bracket member 12 side, the user rotates the lever The screw shaft 14 can be conveniently rotated.

Then, when the lever is rotated to rotate the screw shaft 14 and the second bracket member 13 is moved away from the first bracket member 12, the gap between the guide rolls 30 will be narrowed, When the second bracket member 13 is brought close to the one bracket member 12, the distance between the guide rolls 30 will be long.

As a result, the spacing of the guide rolls 30, which differ according to each segment specification, can also be made similar to the actual segment, so that the result of measuring the quantity of nozzles 5 will be more reliable.

The above description is only one preferred embodiment according to the present invention, and the method of adjusting the interval of the guide rolls 30 may be variously applied according to the user and the usage environment.

 The measuring unit 50 is disposed below the guide roll 30 in order to test the quantity of the nozzle 5 that has completed the repair and maintenance work and confirm the state of repair of the nozzle. Are also installed in the apparatus frame 10. [

The measuring unit 50 collects the cooling water falling down to the lower portion of the guide roll 30 and rotates on the apparatus frame 10 with the rotation guide unit 40 to measure the quantity of the nozzle 5 .

6A to 7B, the measuring unit 50 will be described in detail. The measuring unit 50 includes a collecting tank 51 for collecting cooling water, And a sensor supporting member 52 provided to mount the nozzle non-flow rate measuring sensor 52a and supporting the measuring sensor.

That is, the collecting tank 51 is connected to the apparatus frame 10 on both sides, and has an open top surface disposed below the guide roll 30 to collect cooling water. 6A, a plurality of partition walls 51a are provided in the receiving space S in the longitudinal direction of the guide roll 30, and a receiving space S is provided therein.

The partition wall 51a is provided to grasp the spray area and the quantity of the nozzle 5 by detecting the level of the collected cooling water and is provided to subdivide the cooling water accommodating space S of the collecting tank 51. [

The cooling water 8 injected from the nozzle 5 is dropped and collected in the collecting tank 51 disposed at the lower portion of the guide roll 30 as shown in FIG. When the partitioning wall 51a is provided, the user can check the level of the cooling water 8.

That is, when the plurality of nozzles 5 injects the cooling water, the nozzle 5 injects the cooling water 8 in a form as schematically shown in FIG. 6B. At this time, a large amount of cooling water 8 falls on the partition wall 51a provided at the overlap of the ejection areas, as compared with the other areas.

Therefore, the partition 51a can form a certain level of the cooling water 8 injected from the nozzle 5, and the user who confirms the level of the cooling water can confirm the spray shape and the amount of the nozzle 5 And it is possible to judge whether or not the nozzle repair condition is good.

The collecting tank 51 may be made of a transparent material so that the coolant level can be easily determined by the naked eye. In the present invention, a transparent reinforced acrylic material is presented as an example, but it can be suitably changed depending on the user and the use environment.

If necessary, the collecting tank 51 may be formed of the same material having a completely transparent front surface so that the level of the cooling water collected in the receiving space S can be visually checked easily. However, And this is not also limited by the present invention.

In addition, the level trends derived from the continuous cooling water level measurement using the collecting tank 51 can be used as a sample of a separate sheet, as a sample and other reference data.

A sensor supporting member 52, which is another component of the measuring unit 50, may be provided on the rear surface of the collecting tank 51 in the form as shown in FIG. 6A. That is, the collecting tank 51 and the sensor supporting member 52 are integrally formed and can be easily provided for rotation.

The sensor supporting member 52 is used as shown in FIG. 5B. When the collecting tank 51 rotates 90 degrees on the apparatus frame 10, a measuring sensor mounted on the measuring pad 7 on the upper surface Respectively.

The measurement sensor 52a is a sensor mounted on the measurement pad 7 disposed below the nozzle 5 to measure the quantity of the nozzle 5 on the existing segment, And returns the value so that the quantity of the nozzle 5 can be known.

That is, in the existing segment, after the nozzle having been repaired was mounted on the segment without testing, the measurement frame 6 was installed and the measurement pad 7 was mounted on the upper surface, and the repair status of the nozzle was confirmed based on the value returned by the sensor .

Therefore, if the quantity of the nozzle is checked through the measuring sensor, the nozzle is removed from the segment again and the nozzle is again repaired. Then, the measurement quantity of the nozzle is measured by mounting the measuring frame and the measuring pad on the segment again. The same procedure was repeated until the measurement sensor returned a normal value. In order to prevent such repetition of operation, in the present invention, a sensor supporting member 52 is connected to the rear surface of the collecting tank 51 to be integrally provided.

The measuring unit 50 is provided with the rotation guide unit 40 so as to be easily rotated in the apparatus frame 10 so that the collecting tank 51 and the sensor The positional shift of the support member 51 can be easily realized. The rotation and detailed operation method of the measuring unit 50 will be described later.

 The sensor supporting member 52 is coupled to the rear surface of the collecting tank 51. When the collecting tank 51 rotates 90 degrees on the apparatus frame 10, Is disposed at the lower portion of the guide roll 30, that is, the position where the collecting tank 51 was previously located.

When the position is switched to the collecting tank 51, the upper surface on which the drawing unit 60 is disposed faces downwardly of the guide roll 30.

The lead-in unit 60 is a constitution that allows the same measurement sensor to be mounted on the measurement pad 7 of the segment to be easily inserted into the sensor support member 52. [ Accordingly, in the present invention, the drawing unit 60 is provided with a plat- form roller 61 that is easy to prevent friction, but it is also an item that can be appropriately changed depending on the user and the use environment.

The platen roller 61 may be provided with a stopper at an appropriate position in order to set an appropriate position of the measurement sensor 52a and prevent the deviation of the measurement sensor 52a from the sensor support member 52. [

The user can make the bottom surface of the sensor 52a of the segment come into contact with the upper surface of the platen roller 61 provided as the drawing unit 60 on the upper surface of the sensor supporting member 52, The sensor 52a can be pushed into the sensor supporting member 52 from the sensor 52a to the sensor 52a.

5A and 5B, the rotation and rotation guide unit 40 of the measurement unit 50 will be described in detail. The rotation guide unit 40 includes a rotation plate 41, A locking pin 42, and a plurality of second locking pins 43.

The rotating plate 41 may be fixed to both sides of the collecting tank 51 by welding or the like so as to rotate together with the collecting tank 51 when the collecting tank 51 rotates .

And is coupled to the apparatus frame 10 on the apparatus frame 10 so as to have the same rotational axis A as the collecting tank 51. [ Therefore, the collecting bath 51 can be fixed to the apparatus frame 10 by fixing the rotating plate 41 fixed to both sides of the collecting bath 51 to the apparatus frame 10 and fixing them.

Therefore, the rotation axis A becomes the same rotation axis of the rotation plate 41 and the collection tank 51 on the apparatus frame 10. [ 4, in order to couple the rotary plate 41 to the apparatus frame 10 and to form the rotary shaft of the collecting bath 51 and the rotary plate 41, a high-tension bolt and a nut Can be used.

That is, when the head of the high tension bolt is disposed inside the apparatus frame and the end passes through the rotary plate 41 before passing through the apparatus frame 10, a spring washer is inserted to prevent the bolt from loosening After that, the nuts can be joined and fixed.

At this time, in coupling the high tension bolt and the nut, the coupling strength is set such that the rotation plate 41 is fixed on the apparatus frame 10, but the rotation plate 41 is kept to be rotatable on the apparatus frame desirable.

5A and 5B, one side of which is provided with a hole penetrating to form a rotation axis A on the apparatus frame 10, and the other side end Has a through hole (H) which extends in the rotating direction of the collecting tank (51) and into which a first locking pin (42) to be described later can be inserted.

In other words, all of the rotating plates have two through holes. The holes provided at one side of the rotating plate include a hole for engaging with the apparatus frame 10 by inserting a high-tension bolt for forming the above- And the through hole H formed at the other end of the elongated member is inserted into the collecting tank 51 in a state in which the upper surface of the collecting tank 51 is disposed below the guide roll 30 before the collecting tank 51 rotates, 51 to prevent the rotation of the first locking pin 42 from being inserted.

Therefore, when the other end of the through hole H is extended in the rotational direction of the collecting tank 51 after the rotation axis A is formed, the end of the first locking pin 42, which will be described later, The first locking pin 42 should be machined at a position corresponding to the first locking pin 42. [

The rotating plate 41, which is processed as described above, can rotate together in the same direction when the collecting tank 51 is rotated. The rotation of the rotating plate 41 and the collecting tank 51 can be realized by the first locking pin 42 and the second locking pin 43.

5A shows a state before the collecting bath 51 and the rotating plate 41 are rotated. The collecting bath is provided to collect the cooling water sprayed from the nozzle 5 and falling down to the lower side of the guide roll 30 State.

Then, when the measurement of the quantity of the nozzles 5 is completed by completing the collection of the cooling water and the detection of the level of the collected cooling water, the collecting bath and the rotating plate are rotated 90 degrees to test the measuring sensor 52a, The upper surface of the sensor supporting member 52 coupled to the rear surface of the tank 51 is disposed below the guide roll 30 so that the position of the collecting tank 51 and the sensor supporting member 52 is changed .

At this time, the first locking pin 42 and the second locking pin 43 may be used to rotate the collecting tank and the rotating plate.

7A shows a state of engagement of the first locking pin 42 with respect to the rotation plate 41 and the apparatus frame 10, and the second locking pin 43 ) It is constituted by the same principle as that of the first locking pin only in the position where it is installed.

The first locking pin 42 passes through the apparatus frame 10 and the through hole H of the rotating plate 41 at the same time so that the state in which the first locking pin 42 is penetrated before the rotation of the collecting tank 51 , The upper surface of the collecting tank 51 is disposed below the guide roll 30, and the cooling water is being collected.

Also, as shown in FIG. 7A, the lever 42a can be welded to the side surface of the first locking pin 42 so that the user can move the first locking pin. In addition, a pin case (42b) for receiving the first locking pin may be provided outside the first locking pin.

One end of the pin case 42b is fixed to the apparatus frame 10 and a receiving space for the first locking pin 42 is provided inside the pin case 42b. It means proper space.

Also, as shown in Fig. 7B, the pin case 42b has a lever groove 42c on the outside. Thus, when the lever 42a welded to the first locking pin 42 is moved along the lever groove 42c, the first locking pin 42 can be adjusted to move leftward or rightward on the apparatus frame 10 .

In this case, it is preferable that the lever groove 42c is formed in a 'C' shape as shown in FIG. 7B because the intention of the first locking pin 42 due to the unintentional movement of the lever 42a This is to prevent unauthorized movement.

The first locking pin 42 configured as described above is inserted into the through hole H of the rotary plate 41 through the apparatus frame 10. The second locking pin 43 also passes through the apparatus frame 10 so that the side surface of the pin comes into contact with the front surface of the collecting tank 51. In this state, when the first locking pin 42 is inserted into the through hole H, As shown in Fig.

4, the first and second locking pins 42 and 43 are all inserted through the apparatus frame 10 to the inside of the apparatus frame, 51) is taking place.

At this time, the collecting tank 51 is supported by the side surface of the second locking pin 43 inserted into the inside of the apparatus frame 10, thereby preventing the collecting tank 51 from rotating. Accordingly, the second locking pin 43 has the same principle as the first locking pin 42 described above in order to stably support the collecting tank 51. The length of the pin is larger than that of the first locking pin 42 It may be desirable to provide a long time. Accordingly, it is obvious that the pin case 42b is longer than the pin case of the first locking pin 42 as well.

Thereafter, the first and second locking pins 42 and 43 move the lever 42a along the lever groove 42c, thereby moving the first and second locking pins to the left. The first and second locking pins 42 and 43 are disposed on the outer side of the apparatus frame so that the first locking pin 42 comes out of the through hole H of the rotating plate 41, The contact with the front surface of the collecting tank 51 is released.

5B, the collecting bath 51 and the rotary plate 41 will slowly descend and rotate 90 degrees due to the loose coupling of the high tension bolt and the nut of the rotary shaft A.

5B, the through hole H of the rotation plate 41 is exposed to the outside, and the front surface of the collecting tank 51 comes into contact with the stopper 11, which will be described later. Then, the upper surface of the sensor supporting member is disposed so as to face the lower portion of the guide roll 30 while the position of the collecting tank 51 and the sensor supporting member 52 is changed.

The measurement sensor 52a can be attached to the sensor support member 52 by pulling the measurement sensor 52a along the platform roller 61 provided on the upper surface of the sensor support member 52. [

Here, the user already knows the information such as the quantity and non-water area of the nozzle 5 mounted on the apparatus, the spray distribution, etc. by collecting the cooling water in the collecting tank 51 and measuring the cooling water level.

Therefore, if it is determined that the coolant level is within the normal range, and the coolant level of the nozzle 5 is determined to be good, the measurement sensor 52a can be verified based on a good coolant level value.

That is, the measurement sensor 52a mounted on the sensor support member 52 confirms whether or not a good nozzle water quantity measurement value equal to or similar to the good cooling water level value detected through the collection tank 51 is returned It is possible to test whether the state of the measurement sensor 52a is good or not.

If it is confirmed that the measurement sensor 52a is also within a preferable range, the measurement sensor 52a and the nozzle 5 mounted on the apparatus are removed and mounted in the segment, so that the measurement sensor 52a can be used in the casting process and used .

Meanwhile, the stopper 11, which is in contact with the front surface of the collecting tank 51, determines the lowering position of the collecting tank 51, as shown in FIGS. The first and second locking pins prevent the rotation of the collecting tank 51 and support the collecting tank 51 after the collecting tank 51 is lowered.

However, the lowering speed of the collecting tank 51, which gradually decreases and rotates with respect to the rotating shaft A after the fixing and support by the first and second locking pins 42 and 43 is released, May be determined by the degree of engagement of the high tension bolt and nut to be engaged.

In the present invention, the pins are used as the first and second locking pins 42 and 43 in order to implement the above-described operation of the collecting tank 51 and the sensor supporting member 52. However, , Clamps, and so on.

On the other hand, as the high tension bolts and nuts that are coupled to the rotating shaft A are strongly coupled, the lowering speed of the collecting tub 51 will be slower and the lowering speed of the collecting tub 51 will be accelerated faster.

Therefore, when the high tension bolt and the nut are loosely engaged and the collecting tank 51 descends simultaneously with the rotation prevention release of the first and second locking pins 42 and 43 to come in contact with the stopper 11, 51 may be somewhat impacted. Therefore, in the present invention, a buffer member 11a is provided on the upper surface of the stopper 11 in contact with the front surface of the collecting tank.

The cushioning member 11a is used for the purpose of alleviating an impact that may be applied when the collecting tank 51 is rotated 90 degrees while being brought into contact with the stopper 11. The material of the cushioning member is rubber, Can be used, and the present invention is not limited thereto.

After the test of the nozzle 5 and the nozzle rain rate measurement sensor 52a is completed by the switching of the positions of the collecting tank 51 and the sensor supporting member 52 as described above, If you want to set this device, you can do as follows.

First, the measurement sensor 52a mounted on the upper surface of the sensor supporting member 52 is separated from the sensor supporting member 52. Then, the collecting tank 51 is pushed up again in the direction opposite to the direction in which the collecting tank 51 has rotated 90 degrees while descending.

The upper surface of the collecting tank is arranged to face the lower portion of the guide roll 30 while the collecting tank 51 and the sensor supporting member 52 are again switched in position, And is located on the rear surface of the collecting tank.

Then, the first and second locking pins 42 and 43 can be respectively moved. At this time, the movement of the first and second locking pins is not limited to the order, and the operation methods of the first and second locking pins are the same.

7A, when the lever 42a is moved along the lever groove 42c to move to the position shown in FIG. 7A, the first locking pin 42 is moved Is inserted into the through hole (H) of the rotation support member (41).

The side surface of the second locking pin 43 is in contact with the front surface of the collecting tank 51 so that the collected toner is collected So as to prevent the tank 51 from descending and rotating.

When the above setting is completed, the user can mount the nozzle 5 as described above, and perform cooling water collection work while supplying cooling water and air.

As described above, the constituent elements of the nozzle and nozzle non-flow rate sensor test apparatus according to the present invention can be used alone or in a part of the constituent elements, It should be noted that the combination can be appropriately determined by the working environment and the user.
