BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample loading apparatus, and more particularly, to a sample loading apparatus which can be easily fixed or separated so that it can be easily used in a corrosion test environment.

Corrosion assessment tests on materials are generally performed in a variety of environments and conditions. During the various corrosion evaluation tests, outdoor corrosion evaluation tests assess the extent to which the material is corroded under natural conditions by prolonged exposure of the material to the open air. The test equipment used in these tests shall secure the material for a long time and firmly support the material at the angle required by the quality assessment.

Conventionally, a corrosion evaluation test was conducted by fixing a plurality of workpieces to a cradle that is inclined at a certain angle. Four corners of the square plate shaped material were fixed with bolts. Therefore, when a plurality of workpieces are fixed to a cradle, a lot of workforce is put in, and the work of fixing the corner portions of the workpieces to each other for a long time has to be performed.

Further, when the material is separated from the cradle, there is a problem that the bolt is not disassembled due to corrosion or the like. Therefore, the work time may be delayed by performing additional work for separating the work. As a result, the time for exposing the material to the outdoors is increased, the conditions of the corrosion evaluation test may be different from the first, and if the material is forcibly separated from the cradle, the material may be deformed or damaged.

In addition, the cradle is made heavy and heavy. Therefore, in order to adjust the angle of the assembled cradle once, the entire cradle must be disassembled and reassembled, wasting time and manpower. In addition, it is difficult to install while moving the cradle due to its heavy weight, and inevitably, it takes a lot of cost and resources to move the cradle.

At this time, the sample 10 may be an iron plate, and the extent to which the sample 10 is corroded outdoors or outdoors can be evaluated. However, the material and the corrosion evaluation place of the sample 10 are not limited to this and may be various.

The first frame 110 and the second frame 120 are extended in one direction. The first frame 110 may be formed as a rectangular pipe extending in one direction, for example, vertically. The first frame 110 may have a hollow interior. Accordingly, the weight of the first frame 110 can be reduced, and the sample stacking apparatus 100 can be easily transported.

Also, the first frame 110 may be made of at least one of stainless steel and plastic. That is, since the first frame 110 is exposed to the same environment as the environment in which the sample 10 is exposed, if the first frame 110 is used for a long time, the first frame 110 may be corroded. Therefore, in order to prevent or prevent the first frame 110 from being corroded, the first frame 110 can be manufactured using at least one of stainless steel and plastic having excellent corrosion resistance.

The first frame 110 may have a first engaging member 111 at one end thereof. For example, the first engaging member 111 may be provided at an upper end of a side of the first frame 110 facing the second frame 120. The first coupling member 111 is rotatably connected to the rotation unit 150 in a part thereof. However, the shape and material of the first frame 110 are not limited to these, and may be various.

The second frame 120 may be formed in the form of a rectangular pipe extending in one direction, for example, vertically. The second frame 120 may have a hollow interior. Accordingly, the weight of the second frame 120 can be reduced, and it becomes easy to carry the sample stacking apparatus 100.

Also, the second frame 120 may be made of at least one of stainless steel and plastic. That is, since the second frame 120 is exposed to the same environment as the environment in which the sample 10 is exposed, if the second frame 120 is used for a long time, the second frame 120 may be corroded. Therefore, in order to suppress or prevent the corrosion of the second frame 120, the second frame 120 can be manufactured using at least one of stainless steel and plastic having excellent corrosion resistance.

The second frame 120 may have a second coupling member 121 at one end thereof. For example, the second engaging member 121 may be provided at an upper end of a side of the second frame 120 facing the first frame 110. The second coupling member 121 is rotatably connected to the rotation unit 150 in a part thereof. However, the shape and material of the first frame 110 are not limited to these, and may be various.

The rotating unit 150 is rotatably connected to one end of the first frame 110 and one end of the second frame 120. That is, one side of the rotation unit 150 is rotatably connected to one end of the first frame 110, and the other side of the rotation unit 150 is rotatably connected with one end of the second frame 120. For example, the rotating unit 150 may be formed in the form of a connecting pin extending along the periphery of the rectangle. One side of the rotation unit 150 is connected to the first coupling member 111 of the first frame 110 and the other side of the rotation unit 150 is connected to the second coupling member 121 of the second frame 120. [ Respectively. Accordingly, the first frame 110 and the second frame 120 are disposed to face each other.

When the upper end of the first frame 110 or the upper end of the second frame 120 is rotated up and down with respect to the rotation unit 150, the inclination of the first frame 110 or the inclination of the second frame 120 Can be adjusted. Therefore, the supporting angle of the sample 10 can be adjusted. However, the structure and shape of the rotation unit 150 are not limited to this, and may vary.

The plurality of support units 130 are installed on the first frame 110 and the second frame 120 and are movable along the extending direction of the first frame 110 or the second frame 120 And are arranged in a line along the extension direction of the first frame 110 or the second frame 120 so as to support the sample 10. [ That is, a plurality of support units 130 are installed in the first frame 110 and the second frame 120, respectively, to fix or support the sample 10.

The support unit 130 may be formed in a rectangular ring shape and protrude outwardly of the first frame 110 or the second frame 120. Thus, the sample 10 can be seated on the support unit 130. For example, the plurality of support units 130 are installed in a line in the first frame 110 or the second frame 120 in the vertical direction, and the sample 10 is stacked between the plurality of support units 130 . That is, the lower support unit 130 supports the lower end of the sample 10 with respect to one sample 10, and the upper support unit 130 supports the upper end of the sample 10.

In addition, an insertion groove 131 into which the sample 10 is inserted may be formed on at least one of upper and lower portions of the support unit 130 to stably support the sample 10. For example, the insertion groove 131 may be formed along the upper or lower shape of the sample 10 so that the upper or lower portion of the sample 10 can be inserted. The sample 10 is sandwiched between the insertion grooves 131 of the upper support unit 130 and the insertion grooves 131 of the lower support unit 130 and can be stably fixed and the sample 10 is slid .

According to the embodiment of the present invention, four support units 130 may be provided for each of the frames 110 and 120, and the first support unit 130a, the second support unit 130b, A third support unit 130c, and a fourth support unit 130d.

Since the sample 10 is not placed on the upper portion of the first support unit 130a disposed on the uppermost side of the plurality of support units 130, the uppermost support unit 130a has the insertion groove 131 formed only at the lower portion thereof . Since the sample 10 is not supported under the fourth support unit 130d disposed at the lowermost side among the plurality of support units 130, the fourth support unit 130d has the insertion groove 131 formed only at the upper portion thereof . In the case of the second supporting unit 130b and the third supporting unit 130c disposed between the first supporting unit 130a and the fourth supporting unit 130d among the plurality of supporting units 130, Grooves 131 may be formed to stably support the sample 10.

In addition, the plurality of support units 130 can move up and down along the extension direction of the first frame 110 or the second frame 120. The distance between the upper support unit 130 and the lower support unit 130 is adjusted to the height of the sample 10 so that the sample 10 can be detached from the sample 10. [ . ≪ / RTI >

When the plurality of samples 10 are fixed to the supporting unit 130, the lower part of the lower sample 10 is fixed by the lower supporting unit 130 and the upper part of the lower sample 10 is fixed to the upper supporting unit 130 130 by the weight of the upper sample 10 seated on the upper side. That is, the sample 10 can be stably supported by the upper supporting unit 130 and the lower supporting unit 130 by the force or the weight pressing the lower side of the upper sample 10. Therefore, the sample 10 can be stably supported using the weight of the sample 10.

At this time, a fixing member 135a for fixing the position of the plurality of support units 130 to the support unit 130 closest to the rotation unit 150, that is, the first support unit 130a disposed on the uppermost side, Respectively. In the case of the first supporting unit 130a, since the sample 10 is not seated on the upper part, the sample 10 may not be stably fixed because there is no force for pressing down the sample 10 connected to the lower part. Therefore, after inserting the upper portion of the sample 10 into the insertion groove 131 of the first supporting unit 130a, the position of the first supporting unit 130a can be fixed by using the fixing member 135a .

The fixing member 135a may be formed in the form of a TiVo and may be installed through one side of the uppermost support unit 130a. Thus, if the fixing member 135a is loosened, the supporting unit 130 can move up and down. If the fixing member 135a is tightened, the uppermost supporting unit 130a may not move up and down. However, the method of fixing the shape of the fixing member 135a and the position of the uppermost support unit 130a is not limited to this and may be various.

On the other hand, the movement of the fourth support unit 130d may be restricted to prevent the fourth support unit 130d from being separated from the first frame 110 or the second frame 120. [ That is, when the fourth support unit 130d is released to the lower portion of the first frame 110 or the second frame 120, the upper support units 130a, 130b, 130c and the sample 10 can be separated . Therefore, it is necessary to prevent the fourth support unit 130d from being disengaged. For example, the adjustment unit 140 connected to the lower end of the first frame 110 and the lower end of the second frame 120 can be prevented from moving to the lower side of the fourth support unit 130d. That is, it is possible to prevent the fourth support unit 130d from being caught by the adjustment unit 140 and being released to the lower portion of the first frame 110 or the lower portion of the second frame 120. [

Alternatively, a separation preventing jaw (not shown) may be formed on the lower portion of the first frame 110 or the lower portion of the second frame 120 to prevent the fourth supporting unit 130d from being separated. Alternatively, the fourth support unit 130d may be fixed to the lower portion of the first frame 110 or the lower portion of the second frame 120 so that the fourth support unit 130d can not move. However, the method of preventing the fourth support unit 130d from being released is not limited to this and may be various.

Further, the support unit 130 may be made of at least one of stainless steel and plastic. That is, when the support unit 130 is used for a long time, the support unit 130 may be corroded because the support unit 130 is exposed to the same environment as the environment in which the sample 10 is exposed. Therefore, in order to suppress or prevent the corrosion of the support unit 130, the support unit 130 can be manufactured using at least one of stainless steel and plastic excellent in corrosion resistance. Thus, the problem of separation of the sample 10 due to the corrosion of the support unit 130 can be prevented, and maintenance of the support unit 130 can be facilitated. However, the structure, shape, number, and materials of the support unit 130 are not limited to these, and may be various.

The control unit 140 is connected to the other end of the first frame 110 and the other end of the second frame 120 and connects the other end of the first frame 110 and the other end of the second frame 120 You can adjust the separation distance. That is, the adjustment unit 140 adjusts the distance between the lower end of the first frame 110 and the lower end of the second frame 120 to adjust the inclination angle of the first frame 110 and the second frame 120 . The adjusting unit 140 includes a bolt 141 passing through the other end of the first frame 110 and the other end of the second frame 120, a nut 142 fastened to one end of the bolt 141, And an elastic member 143 disposed between the other end of the first frame 110 and the other end of the second frame 120 and providing elastic force in a direction of extension of the bolt 141.

The bolt 141 extends in the left-right direction and passes through the first through-hole 112 formed at the lower end of the first frame 110 and the second through-hole 122 formed at the lower end of the second frame 120. The head portion of the bolt 141 is engaged with the first through hole 112 and the nut 142 is fastened to the portion of the bolt 141 that penetrates the second through hole 122. The bolt 141 is provided with an elastic member 143 extending in the left and right direction and disposed between the lower end of the first frame 110 and the lower end of the second frame 120. For example, the elastic member 143 may be a spring.

When the nut 142 is tightened, the elastic member 143 contracts and the distance between the lower end of the first frame 110 and the lower end of the second frame 120 decreases. Accordingly, the angle between the first frame 110 and the second frame 120 can be reduced as the first frame 110 and the second frame 120, which have been inclined, are erected upright. The elastic member 143 urges the lower end of the first frame 110 and the lower end of the second frame 120 by the resilient force so that the lower end of the first frame 110 and the lower end of the second frame 120, The separation distance between the lower ends of the upper surface 120 increases. Accordingly, the degree of inclination of the first frame 110 and the second frame 120 can be increased.

The bolt 141 is provided with a scale indicating the inclined angle of the first frame 110 and the second frame 120 according to the distance between the lower end of the first frame 110 and the lower end of the second frame 120 Not shown) may be formed. Accordingly, when the nut 142 is moved according to the position of the scale, the tilted angle of the first frame 110 and the second frame 120 can be easily adjusted to a desired angle. Thus, the tilted angle of the sample 10 can be easily adjusted according to the test requirements for the sample 10. However, the structure and shape of the adjustment unit 140 and the method of adjusting the tilted angle of the sample 10 are not limited to these and may vary.

3, the first frame 110, the second frame 120, and the rotation unit 150 are arranged in a line in a direction intersecting with the one direction, for example, in a longitudinal direction crossing the up and down direction . That is, the first frame 110, the second frame 120, and the rotation unit 150 can be supported to support a large amount of the sample 10 in order to simultaneously perform a corrosion test for a large amount of the sample 10, Can be arranged in a line.

 At this time, the connection unit 160 can connect the plurality of rotation units 150. For example, the connection unit 160 may be a coupling capable of being detachably coupled. The connection unit 160 includes a first body 161 connected to one end of the rotation unit 150 and formed with a groove and a second body 161 connected to the other end of the rotation unit 150, And a second body 162, which is shown in Fig.

A second body 162 connected to one rotation unit 150 of the plurality of rotation units 150 is coupled to a first body connected to the other rotation unit 150. That is, one side of the first body 161 is connected to the front rotary unit 150 of the plurality of rotary units 150, and the other side is formed with a groove. One end of the second body 162 is inserted into the groove of the first body 161 and is connected to the rear rotation unit 150 of the plurality of rotation units 150. When the second body 162 is connected to the first body 161, the front rotation unit 150 and the rear rotation unit 150 are connected to each other.

Also, the first body 161 and the second body 162 can be coupled to and separated from each other. Therefore, when the sample-and-hold device 100 is moved, the first body 161 and the second body 162 can be separated to move the parts of the sample-and-hold device 100 individually. Therefore, the mobility of the sample stacking apparatus 100 can be improved since the lightweight portions are moved as compared with the case of moving the heavy one sample stacking apparatus.

In addition, the first body 161 and the second body 162 may be rotatably coupled to each other. Therefore, the first frame 110 and the second frame 120 in front can be individually inclined to the rear first frame 110 and the second frame. That is, even if the inclination of the first frame 110 and the second frame 120 at the front is adjusted, the first body 161 rotates to affect the first frame 110 and the second frame 120 It can suppress or prevent giving. Since the tilted angles of the first frame 110 and the second frame 120 can be individually adjusted to adjust the tilted angles of the samples 10, It is possible to reduce the waste of time and manpower in comparison with the conventional method of disassembling and reassembling the entire sample rack to adjust the angle.

 As described above, it is easy for the sample-and-hold unit 100 to hold or separate the sample 10 by supporting the sample 10 in a laminated manner. Therefore, since the sample 10 is easily detached and adhered to perform the corrosion test, it is possible to save time used for performing the corrosion test. In addition, it is possible to prevent the support unit 130 supporting the sample 10 from being corroded. Therefore, the sample can be securely fixed or separated to the supporting unit 130. [

Further, since the sample mounting apparatus 100 can be separated into a plurality of units, it is easier to carry than one sample mounting apparatus 100 when it is carried. Therefore, the sample stacking apparatus 100 can be transported quickly, and the preparation time for the corrosion test can be shortened. In addition, the adjustment unit 140 can be used to easily adjust the tilted angle of the samples 10. Therefore, the reliability of the test can be improved by adjusting the tilted angle of the sample 10 in accordance with the test requirements.

Hereinafter, a method of fixing the sample 10 to the sample mounting apparatus 100 according to the embodiment of the present invention will be described.

First, the sample mounting apparatus 100 can be installed at a place where the test is to be performed, for example, in the outdoors. The first frame 110 and the second frame 120 of the sample-and-hold device 100 are then subjected to the test conditions before fixing the sample 10 to the sample mounting device 100, Adjust the tilt angle.

The sample 10 can be fixed to the sample-and-hold device 100 in the same order as in Fig. 4 (a). For example, when four support units 130 are installed in the first frame 110 or the second frame 120, the first support unit 130a and the second support unit 130b , A third support unit 130c, and a fourth support unit 130d.

First, the lowermost fourth support unit 130d is moved to the lowermost end of the first frame 110 or the second frame 120, and the other support units 130 are moved upward. Then, the sample 10 is fitted into the insertion groove 131 of the fourth supporting unit 130d and the third supporting unit 130c is moved downward to move the upper part of the sample 10 to the third supporting unit 130c.

Next, the next sample 10 is put on the upper insertion groove 131 of the third support unit 130c and the second support unit 130b is moved downward to move the upper part of the sample 10 to the second support Into the lower insertion groove 131 of the unit 130b. At this time, the third supporting unit 130c is given a force to move downward by the weight of the sample 10 placed on the third supporting unit 130c. Therefore, the sample 10 under the third support unit 130c can be stably supported by being sandwiched between the fourth support unit 130d and the third support unit 130c.

Next, the next sample 10 is put on the upper insertion groove 131 of the second support unit 130b and the first support unit 130a is moved downward to move the upper part of the sample 10 to the first support Into the lower insertion groove 131 of the unit 130a. At this time, the second support unit 130b is given a force to move downward by the weight of the sample 10 placed on the second support unit 130b. Therefore, the sample 10 under the second supporting unit 130b can be stably sandwiched between the third supporting unit 130c and the second supporting unit 130b.

Then, the fixing member 135a is tightened to fix the position of the first supporting unit 130a. Thus, the sample 10 can be stably supported by being sandwiched between the second supporting unit 130b and the first supporting unit 130a. If the sample 10 is fixed in the reverse order, the support units 130b, 130c, and 130d other than the first support unit 130a are not fixed properly, and the sample 10 can not be stably supported. Accordingly, after fixing the positions of the second, third, and fourth supporting units 130d by using the weight of the samples 10 in the above-described order, the position of the first supporting unit 130a is fixed to the fixing member 135a The sample 10 can be stably fixed.

Conversely, the sample 10 can be separated from the sample-and-hold device 100 in the same order as in FIG. 4 (b). First, the fixing member 135a is released so that the state of the first supporting unit 130a becomes movable. The first supporting unit 130a is moved upward to separate the sample 10 from the sample.

The sample 10 inserted into the upper insertion groove 131 of the second supporting unit 130b is then separated and the second supporting unit 130b is moved upward to move the sample 10). The sample 10 inserted into the upper insertion groove 131 of the third supporting unit 130c is then separated and the third supporting unit 130c is moved upward to move the sample 10). Then, the sample 10 inserted into the upper insertion groove 131 of the fourth supporting unit 130d is separated. However, the number of the support units 130 is not limited to this, and may vary.

As described above, it is easy for the sample-and-hold unit 100 to hold or separate the sample 10 by supporting the sample 10 in a laminated manner. Therefore, since the sample 10 is easily detached and adhered to perform the corrosion test, it is possible to save time used for performing the corrosion test.

In the above description, the sample is placed on the sample rack to perform the corrosion evaluation test on the sample. However, the present invention is not limited to this, and the present invention can be applied to apparatuses for stacking samples in various environments.

Although the present invention has been described in detail with reference to the specific embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be defined by the appended claims, as well as the appended claims.
