이를 보다 구체적으로 설명한다. This will be described in more detail.
콘 관입시험장치(10)는, 해저면에 안착되는 프레임(12)과, 프레임(12)을 해저면에 고정시키는 다수개의 버켓기초(18)와, 프레임(12)에 수직으로 설치되는 서포트(19)와, 프레임(12)의 상면 설치되는 지지체(14A)을 구비한 관입모듈(14)과, 지지체(14A)에 마련되는 구동부재(16)에 의해 서로 맞물리는 방향으로 회전하도록 지지체(14)의 내부에 마련되는 한 쌍의 제1,2 관입 로울러(20A,20B)를 포함하여 구성된다. The cone penetration test apparatus 10 includes a frame 12 seated on the sea floor, a plurality of bucket foundations 18 fixing the frame 12 to the sea floor, and a support installed vertically on the frame 12 ( 19), the penetration module 14 having a support body 14A installed on the upper surface of the frame 12, and the support body 14 so as to rotate in the direction of engagement with each other by the driving member 16 provided on the support body 14A. ) It is configured to include a pair of first and second penetration rollers 20A and 20B provided inside.
관입모듈(14)은, 구동부재(16)의 구동에 의해 제1,2 관입 로울러(20A,20B)가 서로 맞물리는 방향으로 정회전 또는 역회전하면서 콘 프로브가 단부에 결합된 로드(30)를 수직 하향으로 이동시켜 해저지반으로 관입하거나, 수직 상향으로 이동시켜 해저지반으로터 회수하도록 작동된다. 구동부재(16)의 축에는 구동 피니언(16A)이 결합된다. 제1 관입 로울러(20A)의 축과 제2 관입 로울러(20B)의 로울러 축(25)에는 서로 맞물리는 한 쌍의 피동기어(21A,21B)가 결합된다. The penetration module 14 rotates forward or backward in the direction in which the first and second penetration rollers 20A and 20B are engaged with each other by the drive of the driving member 16, and the rod 30 to which the cone probe is coupled to the end It is operated to penetrate the seabed ground by moving it vertically downward or to recover it from the seabed ground by moving it vertically upward.

A pair of driven gears 21A and 21B meshing with each other are coupled to the shaft of the first penetrating roller 20A and the roller shaft 25 of the second penetrating roller 20B.
제1,2 관입 로울러(20A,20B)는, 외주면에 로드(30)의 외주면(31)과 같거나 큰 곡률로 형성되는 오목한 가압면(22A,22B)가 각각 형성된다. 가압면(22A,22B)이 로드(30)의 외주면(31)과 같거나 큰 곡률로 오목하게 형성되는 것은, 가압면(22A,22B)과 로드(30)의 접촉 면적을 확장시켜 밀착 가압력이 향상되도록 하기 위한 것이다. The first and second penetrating rollers 20A and 20B are formed with concave pressing surfaces 22A and 22B having the same or greater curvature as the outer circumferential surface 31 of the rod 30, respectively. The fact that the pressing surfaces 22A and 22B are concavely formed with a curvature equal to or greater than that of the outer circumferential surface 31 of the rod 30 expands the contact area between the pressing surfaces 22A and 22B and the rod 30, thereby increasing the contact pressure. is to improve.
제1,2 관입 로울러(20A,20B)의 각 가압면(22A,22B)에 형성되는 슬립방지돌기(24A,24B)는, 양쪽의 제1,2 관입 로울러(20A,20B)로 로드(30)를 가압하여 상향 또는 하향으로 이동시킬 때 로드(30)의 외주면(31)을 찍힘홈(31A)들을 형성하면서 파고들어 접촉면에서의 슬립을 방지하는 기능을 한다. 그리고, 양쪽의 제1,2 관입 로울러(20A,20B)로 로드(30)를 가압하여 상향 또는 하향으로 이동시킴에 따라 로드(30)의 외주면(31)에 형성되는 찍힘홈(31A)의 깊이를 토대로 가압면(22A,22B)에 형성된 슬립방지돌기(24A,24B)의 마모 여부를 파악하여 제1,2 관입 로울러(20A,20B)의 교체여부를 판단한다. The anti-slip protrusions 24A and 24B formed on the pressing surfaces 22A and 22B of the first and second penetrating rollers 20A and 20B are rods 30 to both first and second penetrating rollers 20A and 20B. ) is pressed and moved upward or downward, it penetrates the outer circumferential surface 31 of the rod 30 while forming grooves 31A to prevent slipping on the contact surface. And, as the rod 30 is moved upward or downward by pressing the rod 30 with the first and second penetrating rollers 20A and 20B on both sides, the depth of the stamped groove 31A formed on the outer circumferential surface 31 of the rod 30 Based on this, it is determined whether the first and second penetrating rollers 20A and 20B are replaced by determining whether the anti-slip protrusions 24A and 24B formed on the pressing surfaces 22A and 22B are worn.
한편, 슬립방지돌기(24A,24B)들은 도 2 및 도 5에 도시된 바와 같이, 로드(30)의 외주면(31)을 가압할 때 외주면(31)에 파고 들어 찍힘홈(31A)의 단면이 삼각형으로 형성되도록 끝단부(24A-1,24B-1)가 선으로 형성된다. 슬립방지돌기(24A,24B)들의 끝단부(24A-1,24B-1)가 선을 이룸으로써 뾰족하게 형성되며, 슬립방지돌기(24A,24B)들에 의해 형성되는 찍힘홈(31A)은 안쪽에서 외측으로 확장된 삼각형을 이룬다. On the other hand, as shown in FIGS. 2 and 5, the anti-slip protrusions 24A and 24B penetrate into the outer circumferential surface 31 when pressing the outer circumferential surface 31 of the rod 30, so that the cross section of the groove 31A is formed. The end portions 24A-1 and 24B-1 are formed into lines so as to be formed into triangles. The end portions 24A-1 and 24B-1 of the anti-slip protrusions 24A and 24B are formed sharp by forming a line, and the anti-slip protrusions 24A and 24B form a stamped groove 31A on the inside form an outwardly extended triangle.
전술한 바와 같이, 슬립방지돌기(24A,24B)들의 끝단부(24A-1,24B-1)가 선을 이루는 슬립방지돌기(24A,24B)들은 도 2 및 도 5에 도시된 바와 같이, 로드(20)에 대하여 직각으로 교차하는 방향으로 각각 형성된다. 슬립방지돌기(24A,24B)들은 제1,2 관입 로울러(20A,20B)의 회전축과 같은 방향으로 배열되어 로드(20)에 접촉되었을 때 로드(20)과 직각으로 교차하는 방향으로 접촉된다. 가압면(22A,22B)이 외주면(31)의 곡률과 같거나 큰 곡률로 형성되므로 선으로 이루어진 슬립방지돌기(24A,24B)의 끝단부(24A-1,24B-1)가 로드(30)의 길이 방향에 대하여 직각으로 교차되는 방향으로 로드(30)의 외주면(31)을 감싸면서 가압하기 때문에 가압면(22A,22B)과 외주면(31) 사이에서 슬립이 발생되지 않게 되고, 외주면(31)에는 찍힘홈(31A)들이 연이어 형성된다. As described above, the anti-slip protrusions 24A and 24B forming a line at the ends 24A-1 and 24B-1 of the anti-slip protrusions 24A and 24B are rods, as shown in FIGS. (20) are formed in a direction crossing at right angles. The anti-slip protrusions 24A and 24B are arranged in the same direction as the rotational axes of the first and second penetrating rollers 20A and 20B, and are in contact with the rod 20 at right angles when in contact with the rod 20. Since the pressing surfaces 22A and 22B are formed with a curvature equal to or larger than the curvature of the outer circumferential surface 31, the ends 24A-1 and 24B-1 of the anti-slip protrusions 24A and 24B made of lines form a rod 30 Since the outer circumferential surface 31 of the rod 30 is pressed while wrapping in a direction perpendicular to the longitudinal direction of the rod 30, slip does not occur between the pressing surfaces 22A and 22B and the outer circumferential surface 31, and the outer circumferential surface 31 ), the stamped grooves 31A are formed in succession.

As shown in FIG. 6, in another embodiment of the above-described anti-slip protrusions 24A and 24B, when the outer circumferential surface 31 of the rod 30 is pressed, the outer circumferential surface 31 is dug into the cut groove 31A. The end portions 24A-1 and 24B-1 are formed as dots so that they are formed in a conical shape.

가압조절수단(50)은 조절볼트(56)를 조이고 푸는 조작에 의해 제2 관입 로울러(20B)를 로드(30) 쪽으로 가압하거나 가압력을 해제하는 등의 가압력을 조절할 수 있다. 조절볼트(56)들을 조인 상태에서 각 탄성체(58)가 제2 관입 로우러(20B)의 양단을 동시에 로드(30) 쪽으로 가압하므로 제2 관입 로우러(20B)의 슬립방지돌기(24B)들은 탄력적으로 로드(30)의 외주면에 밀착어 슬립이 더욱 방지된다. The pressure adjusting means 50 may adjust the pressing force, such as pressing the second penetrating roller 20B towards the rod 30 or releasing the pressing force by tightening and loosening the adjusting bolt 56. In the state where the adjustment bolts 56 are tightened, each elastic body 58 simultaneously presses both ends of the second penetrating roller 20B toward the rod 30, so the anti-slip protrusions 24B of the second penetrating roller 20B are It elastically adheres to the outer circumferential surface of the rod 30 to further prevent slip.
이와 같이, 구성된 교체시기 판단 및 슬립방지 구조를 갖는 콘 관입시험장치용 관입 로울러의 작용을 설명한다. Thus, the operation of the penetration roller for the cone penetration tester having the replacement time determination and the anti-slip structure will be described.
관입모듈(10)를 작동시키기 전에, 조절볼트(56)를 조이거나 풀어 제2 관입 로울러(20B)가 로드(30)를 가압하는 가압력을 조절한다. Before operating the penetration module 10, the second penetration roller 20B adjusts the pressure applied to the rod 30 by tightening or loosening the adjusting bolt 56.
이어서, 관입모듈(10)을 이용하여 콘 프로브가 결합된 로드(30)를 관입시키거나 관입된 로드(30)를 회수할 경우에 구동부재(16)를 정회전 또는 역회전 시킨다.Subsequently, when the penetration module 10 is used to penetrate the rod 30 to which the cone probe is coupled or to recover the penetrated rod 30, the driving member 16 is rotated forward or backward.
예를 들어, 구동부재(16)의 정회선 작동시키면, 로드(30)를 기준으로 양쪽의 제1,2 관입 로울러(20A,20B)가 서로 맞물리는 방향으로 회전한다. For example, when the driving member 16 is operated in a forward rotation, the first and second penetration rollers 20A and 20B on both sides of the rod 30 rotate in a direction in which they are engaged with each other.
전술한 과정으로 서로 맞물리는 방향으로 회전하는 제1,2 관입 로울러(02A,20B)의 오목한 가압면(22A,22B)이 로드(30)의 외주면(31) 양쪽에 밀착되어 가압한다. The concave pressing surfaces 22A and 22B of the first and second penetrating rollers 02A and 20B rotating in the direction of engagement with each other in the above-described process are in close contact with both sides of the outer circumferential surface 31 of the rod 30 and pressurize it.
제1,2 관입 로울러(02A,20B)가 로드(30)의 양쪽에서 외주면(31)을 가압하면, 각 가압면(22A,22B)에 연속하여 형성된 각각의 슬립방지돌기(24A,24B)들이 로드(30)의 외주면(31)을 파고들어 찍히게 된다. When the first and second penetrating rollers 02A and 20B press the outer circumferential surface 31 from both sides of the rod 30, the anti-slip protrusions 24A and 24B formed successively on each of the pressing surfaces 22A and 22B The outer circumferential surface 31 of the rod 30 is dug into and stamped.
이와 같이 제1,2 관입 로울러(02A,20B)가 로드(30)의 양쪽을 가압할 때 각각의 슬립방지돌기(24A,24B)들이 로드(30)의 외주면(31)을 파고들어 찍음으로써 제1,2 관입 로울러(02A,20B)의 가압면(22A,22B)과 로드(30)의 외주면(31) 사이에서 슬립이 발생되지 않는다. In this way, when the first and second penetrating rollers 02A and 20B press both sides of the rod 30, the respective anti-slip protrusions 24A and 24B dig into the outer circumferential surface 31 of the rod 30, thereby removing No slip occurs between the pressing surfaces 22A and 22B of the 1 and 2 penetration rollers 02A and 20B and the outer circumferential surface 31 of the rod 30.
한편, 작업자는 슬립방지돌기(24A,24B)들이 로드(30)의 외주면(31)을 파고듦에 따라 로드(30)의 외주면(31)에 형성된 찍힘홈(31A)의 깊이를 토대로, 슬립방지돌기(24A,24B)들의 마모 상태를 파악한다. On the other hand, as the anti-slip protrusions 24A and 24B dig into the outer circumferential surface 31 of the rod 30, the operator prevents slipping based on the depth of the groove 31A formed on the outer circumferential surface 31 of the rod 30. The wear state of the protrusions 24A and 24B is grasped.
예를 들어, 찍힘홈(31A)의 형상이 슬립방지돌기(24A,24B)의 끝단부(24A-1,24B-1) 형상과 같은 삼각형을 이루고 있다면, 슬립방지돌기(24A,24B)의 마모가 발생하지 않은 상태이고, 찍힘홈(31A)의 형상이 삼각형을 이루지 않고 내부 부분이 예리하지 않고 원호형으로 형성되거나, 긁힌 형상 또는 깊이가 얕은 경우에는 슬립방지돌기(24A,24B)의 끝단부(24A-1,24B-1)가 마모되었음을 의미한다. 따라서, 슬립방지돌기(24A,24B)의 끝단부(24A-1,24B-1)가 마모되었음으로 파악되면, 양쪽의 제1,2 관입 로울러(20A,20B)의 교체여부를 판단할 수 있다. For example, if the shape of the stamped groove 31A forms a triangle like the shape of the ends 24A-1 and 24B-1 of the anti-slip protrusions 24A and 24B, wear of the anti-slip protrusions 24A and 24B is not generated, and the shape of the groove 31A is not triangular, the inner portion is not sharp and is formed in an arc shape, or when the scratched shape or depth is shallow, the ends of the anti-slip protrusions 24A and 24B It means that (24A-1, 24B-1) is worn out. Therefore, when it is determined that the ends 24A-1 and 24B-1 of the anti-slip protrusions 24A and 24B are worn, it can be determined whether the first and second penetrating rollers 20A and 20B are replaced. .
이를 위해서, 찍힘홈(31A)의 형상, 깊이 등을 여러 개로 분류하여 표시한 비교표를 만들 수 있고, 작업자는 로드(30)의 외주면(31)에 형성된 찍힘홈(31A)의 형상이나 깊이 등을 비교표와 비교하여 슬립방지돌기(24A,24B)의 끝단부(24A-1,24B-1) 마모 정도를 파악한 후 제1,2 관입 로울러(20A,20B)의 교체여부를 판단할 수 있다. To this end, it is possible to make a comparison table in which the shape and depth of the stamped groove 31A are classified into several categories, and the operator can determine the shape or depth of the stamped groove 31A formed on the outer circumferential surface 31 of the rod 30. It is possible to determine whether to replace the first and second penetrating rollers 20A and 20B after determining the degree of wear of the ends 24A-1 and 24B-1 of the anti-slip projections 24A and 24B by comparing with the comparison table.
이상에서와 같이 관입모듈(10)의 제1,2 관입 로울러(20A,20B)의 가압면(22A,22B)에 슬립방지돌기(24A,24B)들이 형성됨으로써, 양쪽의 제1,2 관입 로울러(20A,20B)가 회전하면서 로드(30)를 양쪽에서 가압하여 상향 또는 하향으로 이동시킬 때 슬립방지돌기(24A,24B)들이 로드(30)의 외주면(31)에 파고들어 슬립을 방지하게 된다. As described above, the anti-slip protrusions 24A and 24B are formed on the pressing surfaces 22A and 22B of the first and second penetrating rollers 20A and 20B of the penetrating module 10, so that both first and second penetrating rollers When (20A, 20B) rotates and presses the rod (30) from both sides to move it upward or downward, the anti-slip protrusions (24A, 24B) dig into the outer circumferential surface (31) of the rod (30) to prevent slipping. .
관입되었던 로드(30)를 회수하여 로드(30)의 외주면에 형성된 찍힘홈(31A)의 깊이나 형태를 통하여 슬립방지돌기(24A,24B)의 마모를 파악할 수 있음으로써 제1,2 관입 로울러(20A,20B)의 교체시키를 판단할 수 있다. By recovering the rod 30 that has been penetrated and determining the wear of the anti-slip protrusions 24A and 24B through the depth or shape of the stamped groove 31A formed on the outer circumferential surface of the rod 30, the first and second penetrating rollers ( 20A, 20B) can be determined to be replaced.
본 발명에 따른 교체시기 판단 및 슬립방지 구조를 갖는 콘 관입시험장치용 관입 로울러는, 각 관입 로울러의 가압면에 돌기들을 연속 형성하여 로드와의 접촉시 슬립이 방지되도록 하고, 로드의 외주면에 찍히는 홈의 깊이에 따라 관입 로울러의 교체시기를 판단할 수 있도록 구성된 것이다. 관입 로울러에 돌기들이 구비됨으로써 슬립이 방지될 수 있고, 로드에 형성되는 찍히는 홈의 깊이를 토대로 로울러의 교체 시기를 판단할 수 있다. 따라서 본 발명에 따른 교체시기 판단 및 슬립방지 구조를 갖는 콘 관입시험장치용 관입 로울러는 콘 관입시험장치의 성능을 향상시킬 수 있는 것이므로 산업상 이용가능성이 있는 발명이다.
