Description

Enclosure Leak Test Equipment { Tank Leak Test Equipment }

The present invention relates to an enclosure leak test equipment, and more particularly, to an enclosure leak test equipment capable of testing whether an enclosure is leaked.

An enclosure such as a tank is constructed by welding and bonding high-strength metal plates, and a plurality of through holes are formed in the circumferential portion.

Since these enclosures are manufactured by welding metal plates, after manufacturing and welding are completed, it is necessary to inspect whether water leakage occurs at the welding part.

However, when performing a leak test of such an enclosure, it is common for an operator to visually inspect a welding part with the naked eye, so it is difficult to effectively confirm that leaks occur in the enclosure, and a problem in that the inspection time takes a long time has occurred. .

Therefore, a 'leak inspection device' is posted in Registered Patent No. 10-1998048 that can solve this problem.

However, since this conventional enclosure leak test equipment uses an articulated robot arm designed to put in or take out the enclosure from the water tank, the overall cost of the equipment increases.

In addition, in order to observe the entire circumference of the enclosure, it takes time because the operator must observe while moving around the water tank, and there is a risk of omission because the operator must directly observe whether or not there is water leakage.

In addition, when the upper part of the enclosure is opened, a means (cover) for sealing it is not robust, and when the enclosure is placed in a water tank, there is a problem that water may flow into the enclosure.

It is a side operation process in a state in which the enclosure is immersed in a water tank by the enclosure leak test equipment according to the embodiment, FIG. 4 is a plan view showing a state in which the enclosure is rotated in FIG. 3, and FIG. 5 is a plan view showing the enclosure in FIG. 6 is a side structural diagram of the enclosure leak test equipment according to the modified first embodiment of the present invention.

As shown in FIGS. 1 and 2, the enclosure leak test equipment of the present invention includes a vertical support 10, an elevating member 20, a vertical connector 30, an upper support 40, and a cylinder ( 41), a gripping part 42, a pedestal 50, a water tank 60, an air supply member 65, and the like.

The vertical support 10 is formed long in the vertical direction.

The lifting member 20 is mounted such that one end is coupled to the vertical support 10 so as to be movable in the vertical direction along the vertical support 10 .

The vertical connecting rod 30 is mounted long in the vertical direction at the other end of the elevating member 20 .

The upper support 40 protrudes from the upper end of the vertical connector 30 in the opposite direction of the vertical support 10 .

The cylinder 41 is mounted downward on the upper support 40 and expands in length in the vertical direction.

The gripping part 42 is mounted on the lower end of the cylinder 41 .

The gripping part 42 is moved vertically by the cylinder 41 .

The holding part 42 grips the enclosure 70 loaded on the upper surface of the pedestal 50 to prevent the enclosure 70 from moving.

The pedestal 50 protrudes from the lower end of the vertical connector 30 in the opposite direction of the vertical support 10 .

The pedestal 50 is disposed by loading the enclosure 70 on the upper surface.

A plurality of rollers 52 are mounted on the upper surface of the pedestal 50, and the enclosure 70 is disposed above the rollers 52.

The enclosure 70 can be easily moved in a horizontal direction by the roller 52 .

When the elevating member 20 moves in the vertical direction, the vertical connector 30, the upper support 40, the cylinder 41, the gripper 42, and the pedestal 50 all move in the vertical direction together.

The water tank 60 is disposed in front of the vertical support 10, and water is filled inside the water tank 60.

The air supply member 65 injects air into the enclosure 70 .

The air supply member 65 is made of a pump or the like and is connected to the enclosure 70 through a hose or the like to supply air.

When the lifting member 20 is lowered in a state in which the enclosure 70 is loaded on the upper surface of the pedestal 50 and air is injected into the enclosure 70 by the air supply member 65 The pedestal 50 is immersed in the water tank 60.

Then, the gripper 42 presses the enclosure 70 disposed at the lower side downward to immerse it in water.

In a state where the enclosure 70 is disposed on the upper surface of the pedestal 50, the cylinder 41 lowers the holding part 42 so that the holding part 42 moves the upper part of the pedestal 70 to the pedestal. By pressing in the direction of (50), the flow of the enclosure (70) is blocked.

A rotating member 45 for horizontally rotating the cylinder 41 based on a vertical line is mounted on the upper support 40.

When the cylinder 41 is contracted while the enclosure 70 is immersed in water by the gripper 42, the enclosure 70 is buoyant by the air filled in the enclosure 70. The lower surface of the pedestal is spaced apart from the upper surface of the pedestal 50, and the gripping part 42 as shown in FIG. ) The enclosure 70 disposed at the bottom of the pedestal 50 rotates in a spaced state.

Through this, the operator can easily determine whether or not the air supplied to the inside of the enclosure 70 through the air supply member 65 leaks at a location in the water.

Hereinafter, the operation process of the present invention composed of the above configuration will be described.

As shown in FIG. 1, the pedestal 50 is raised to the water surface of the water tank 60, and the enclosure 70 is pushed and loaded on the upper surface of the pedestal 50 in the horizontal direction.

At this time, since the roller 52 is mounted on the upper surface of the pedestal 50, the enclosure 70 can be easily moved in a horizontal direction and loaded on the upper surface of the pedestal 50.

Then, as shown in FIG. 3(a), the cylinder 41 is lowered downward so that the gripping part 42 grips the upper portion of the enclosure 70.

At this time, the holding part 42 prevents the enclosure 70 from moving upward and sideways.

Then, the enclosure 70 is fixed between the gripping part 42 and the pedestal 50 .

Then, air is continuously supplied to the inside of the enclosure 70 by connecting the air supply member 65 to the enclosure 70 .

Then, as shown in FIG. 3(b), the elevating member 20 descends.

When the elevating member 20 descends, the pedestal 50, the enclosure 70, and the gripping part 42 all descend together, and the enclosure 70 is immersed in the water of the water tank 60. It becomes.

When the enclosure 70 is completely immersed in water, as shown in FIG. 3(c), the cylinder 41 slightly raises the holding part 42 while contracting its length.

Then, by the buoyancy of the air filled inside the enclosure 70, the enclosure 70 rises while the lower surface of the enclosure 70 is separated from the upper surface of the pedestal 50.

At this time, the upper part of the enclosure 70 is in a state of being continuously gripped by the gripping part 42 .

As shown in FIG. 4 in this state, when the cylinder 41 and the gripping part 42 are rotated by the rotating member 45, the enclosure 70 gripped by the gripping part 42 It rotates naturally while being spaced apart from the pedestal 50.

At this time, in order to prevent the hose connected to the air supply member 65 from being twisted, the rotating member 45 rotates the gripping part 42 in a forward direction and then in a reverse direction.

Therefore, the operator can easily check whether air leaks out from the entire circumference of the rotating enclosure 70 while being located in one place.

After checking whether or not air is leaking from the enclosure 70, the elevating member 20 is raised as shown in FIG. 5(a).

As the elevating member 20 rises, the gripping part 42 and the pedestal 50 also rise. When the gripping part 42 rises above a certain height, the enclosure 70 is moved by its own weight It can no longer rise and floats on the water.

That is, since the gripping part 42 blocks only the movement of the enclosure 70 in the upward and lateral directions, when the lifting member 20 rises, the gripping part 42 rises together. It is spaced apart from the top of the enclosure 70.

In this state, as the pedestal 50 rises, the upper surface of the pedestal 50 comes into contact with the lower part of the enclosure 70 floating on the top, as shown in FIG. 5 (a).

As shown in FIG. 5 (b), as the elevating member 20 further rises, the pedestal 50 rises above the water surface of the water tank 60, and the lower surface of the enclosure 70 is the pedestal ( 50) is exposed on the surface of the water in a state in contact with the upper surface.

At this time, the connection hose of the air supply member 65 is removed.

After that, as shown in FIG. 5(c), the operator pushes and moves the enclosure 70 in the pedestal 50 in the horizontal direction.

As described above, in the present invention, by injecting air into the enclosure 70 and rotating the enclosure 70, the operator can easily determine whether or not the entire enclosure 70 is leaking in one place.

Meanwhile, as shown in FIG. 6 , the present invention may further include a sensor 81 and a controller 82 .

The sensor 81 is mounted on the water tank 60, etc., and when the enclosure 70 is rotated by the rotating member 45, air flows out of the enclosure 70 immersed in the water of the water tank 60. detect whether or not

The controller 82 controls the rotating member 45 .

When air leaking from the enclosure 70 is detected by the sensor 81 , the control unit 82 stops rotation of the rotation member 45 .

As described above, when air is leaked from the enclosure 70 and the rotation of the rotating member 45 is stopped, the operator can easily grasp that there is a leak in the enclosure 70 at the location where the sensor 81 is mounted. can

Furthermore, the present invention may further include a laser device 83.

The laser device 83 irradiates a laser beam into the water of the water tank 60 .

The laser device 83 can change the laser beam irradiation direction.

When air leaking from the enclosure 70 is detected by the sensor 81, the controller 82 operates the laser device 83 to irradiate a laser beam to the air outlet point of the enclosure 70. Let it be.

Through this, the operator can more accurately and easily determine the air outlet point of the enclosure 70 .

The present invention relates to a jig 100 mounted on an enclosure 160 to test whether the enclosure 160 leaks.

The enclosure sealing jig 100 using the enclosure leak test of the present invention, as shown in FIGS. A pressure member 140 is included.

In this embodiment, the enclosure 160 has an open top or a hole formed thereon.

The cover part 110 is formed in a flat plate shape and covers the top of the enclosure 160 with an open top.

A gasket 111 made of an elastic material is attached to the lower surface of the cover part 110 .

The support plate 120 is disposed spaced apart from the top of the cover part 110 .

The side coupling member 130 has an upper end coupled to the support plate 120 and a lower end protruding downward to be coupled to the side surface of the enclosure 160 .

In this embodiment, an installation hole 131 is formed through the lower portion of the side coupling member 130 .

A bolt 132 is inserted into the installation hole 131 and coupled to the side surface of the enclosure 160 .

The upper and lower pressing member 140 is movably mounted on the support plate 120 in the vertical direction, and the lower end is in contact with the upper surface of the cover part 110 .

In this embodiment, the up and down pressing member 140 includes a lifting shaft 141, a rotation knob 142, and a pressing plate 143.

The lifting shaft 141 is screwed while penetrating the support plate 120 .

The rotation handle 142 is coupled to an upper end of the elevating shaft 141 .

The pressing plate 143 is coupled to the lower end of the lifting shaft 141 and comes into contact with the upper surface of the cover part 110 .

Therefore, when the operator holds the rotation knob 142 and rotates it, the up and down pressing member 140 moves upward or downward with respect to the support plate 120 .

In a state where the cover part 110 covers the upper part of the enclosure 160 , the lower end of the side coupling member 130 is fixedly coupled to the side surface of the enclosure 160 .

Due to the relative descent of the upper and lower pressing members 140 with respect to the support plate 120, the lower surface of the cover part 110 adheres to the upper part of the enclosure 160, and the support plate 120 rises upward. .

At this time, since the side coupling member 130 coupled to the support plate 120 is fixedly coupled to the side surface of the enclosure 160, the support plate 120 is prevented from rising, and as a result, the vertical pressing member 140 ) pushes the cover part 110 downward so that it is more closely adhered to the upper part of the enclosure 160.

Through this, when the open top of the enclosure 160 is tightly closed and air is injected into the enclosure 160, the air is discharged to the outside through the open top of the enclosure 160. It can be prevented.

On the other hand, the upper end of the side coupling member 130 of the present invention may be slidably mounted on the support plate 120 in a horizontal direction.

As described above, by sliding the upper end of the side coupling member 130 in the horizontal direction to the support plate 120, by adjusting the position of the side coupling member 130 according to the size of the enclosure 160, one The upper part of the enclosure 160 of various sizes can be tightly covered and closed using the jig 100 of the.

Since the upper end of the side coupling member 130 is slidably mounted on the support plate 120 in a horizontal direction, it is sufficient to use various sliding structures known in the related art, so a detailed description thereof will be omitted.

In addition, as shown in FIG. 10, the present invention may further include a load cell 150, a display (not shown), a lamp 153, and a control unit 154.

The load cell 150 is composed of a plurality and is mounted along a portion of the cover part 110 in contact with the upper part of the enclosure 160.

The display externally displays the measured value of the load cell 150.

When the upper and lower pressing member 140 presses the cover part 110 to the top of the enclosure 160, each of the load cells 150 measures the load at each part, and the load cell 150 measures the load Values are displayed externally through the display.

Through this, it is possible to easily determine which part of the cover part 110 is pressurized less or more, and take a follow-up measure, that is, adjust the amount of rotation of the upper and lower pressing member 140. Through this, the cover part 110 may pressurize the entire upper portion of the enclosure 160 uniformly.

The lamps 153 are formed in plural numbers, and are mounted on the upper surface of the cover part 110 where the load cell 150 is disposed.

The controller 154 controls on/off of the lamp 153.

If the value measured by the load cell 150 is less than a preset value, the control unit 154 turns on the lamp 153 mounted on the part where the corresponding load cell 150 is placed.

This makes it easier for the operator to visually determine which areas are less pressurized or more pressurized.

As described above, the present invention can effectively seal the inside of the enclosure 160 by covering the top of the enclosure 160 with the top open.

After air is injected into the enclosure equipped with the jig of the present invention through the enclosure leak test equipment of Example 1, it is checked whether air leaks.
That is, in Embodiment 1, the inside of the enclosure placed on the pedestal is already sealed before the gripper descends to grip the enclosure.

The enclosure leak test equipment of the present invention is not limited to the above-described embodiment, and may be variously modified and implemented within the scope of the technical idea of the present invention.
