본 고안은 콘테이너 야적장의 하역설비인 트랜스퍼크레인의 주행시 트랜스퍼크레인의 요동을 방지하기 위하여 크레인의 주행각도를 고정하는 휠요오크(wheelyoke)에 관한 것으로, 특히 휠요오크의 구조를 간단하게 하므로서 가공시간이 단축되어 작업능률 및 생산성이 향상된 주행각도 고정용 휠요오크에 관한 것이다.The present invention relates to a wheel yoke that fixes the traveling angle of a crane to prevent the transfer crane swinging when the transfer crane, which is an unloading facility of a container yard, travels. In particular, the machining time is shortened by simplifying the structure of the wheel yoke. It relates to a wheel yoke for fixing the driving angle improved working efficiency and productivity.
일반적으로, 트랜스퍼크레인은 자체의 중량외에도 상당한 중량을 갖는 콘테이너를 운반하게 되므로 주행시 바퀴에 상당한 하중이 가해져 요동이 빈번히 발생하게 되어 이러한 요동으로 인한 주행방향의 변경 등을 방지하고 일정한 방향으로서 주행성을 보장하기 위하여 주행각도 고정용 휠요오크가 사용되고 있다. 그러나, 이러한 종래의 주행각도 고정용 휠요오크(1)는, 제1도에 도시한 바와같이, 직진주행시, 제1실린더핀(2)이 직진주행요홈(3)내에 삽입되고 브라켓(4)의 일측면(4a)과 돌출단턱(5)이 접하여 트랜스퍼크레인의 직진주행각도를 고정시키며, 예각회전 주행시, 휠요오크(1)가 P점을 중심으로 θ각도로 회전하여 상기 제1실린더(2)가 예각회전요홈(6)내에 삽입되고 제2실린더(2')가 보조요홈(7)내에 삽입되어 일정각(θ)으로의 회전주행각도를 고정시키며, 직각회전주행시 휠요오크(1)가 P점을 중심으로 90 회전하여 제1실린더핀(2)이 직각 회전요홈(8)내에 삽입되고 브라켓(4)의 타측면(4b)이 돌출단턱(9)에 접하는 상태에서 직각주행 각도를 고정하는 구조이다.In general, the transfer crane carries a container having a considerable weight in addition to its own weight, so that a significant load is applied to the wheels during driving, causing frequent fluctuations, thereby preventing a change in the driving direction due to such shaking, and guaranteeing driving performance as a constant direction. In order to achieve this, a wheel yoke for fixing a driving angle is used. However, in the conventional driving angle fixing wheel yoke 1, as shown in FIG. 1, when traveling straight, the first cylinder pin 2 is inserted into the straight traveling groove 3 and the bracket 4 One side surface 4a and the protruding step 5 are in contact with each other to fix the straight traveling angle of the transfer crane, and when driving at an acute rotation, the wheel yoke 1 rotates at an angle θ about the point P so that the first cylinder 2 is rotated. Is inserted into the acute turning recess 6 and the second cylinder 2 'is inserted into the auxiliary recess 7 to fix the rotational driving angle to a certain angle θ, and the wheel yoke 1 is 90 degrees around the point, the first cylinder pin (2) is inserted into the right angle groove (8) and the other side (4b) of the bracket (4) to fix the right angle driving angle in contact with the protruding step (9) Structure.
따라서, 종래의 휠요오크의 구조는 직진주행요홈, 예각 회전요홈, 보조요홈, 직각회전요홈 및 돌출단턱을 한정된 공간에 형성하여야 하므로 휠요오크의 구조가 복잡하게 되어 가공이 대단히 어려운 구조를 가지므로 제품의 불량율이 대단히 높고 장시간의 가공을 요하므로 생산성이 낮다는 문제점이 있었다.Therefore, the structure of the conventional wheel yoke is to form a straight running groove, an acute turning groove, an auxiliary groove, a right angle turning groove and a protrusion step in a limited space, so that the structure of the wheel yoke is complicated and has a very difficult structure because of the product Since the defective rate of is very high and requires a long time processing, there was a problem that the productivity is low.
본 고안의 목적은 이러한 문제점을 해결하기 위한 것으로 휠요오크의 구조를 간단히 하므로서 가공시간이 단축되어 작업능률 및 생산성이 향상될 수 있게 하는 것이다.The purpose of the present invention is to solve this problem and to simplify the structure of the wheel yoke, the processing time can be shortened to improve the work efficiency and productivity.
본 고안의 이러한 목적은 휠요오크의 구조를 보다 간단하게 한 본 고안에 따른 주행각도 고정용 휠요오크에 의하여 달성된다.This object of the present invention is achieved by a wheel angle fixing wheel yoke according to the present invention, which makes the structure of the wheel yoke simpler.
이하 본 고안에 따른 트랜스퍼크레인의 주행각도 고정용 휠요오크를 첨부된 도면을 참고로 하여 이하에 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the wheel yoke for fixing the traveling angle of the transfer crane according to the present invention will be described in detail.
본 고안에 따른 휠요오크(10)는 제2도에 도시한 바와같이, 직진주행요홈(11)과, 예각회전요홈(12)과, 직각회전요홈(13)이 형성되어 있다.As shown in FIG. 2, the wheel yoke 10 according to the present invention includes a straight traveling recess 11, an acute turning recess 12, and a right turning recess 13.
상기 직진주행요홈(11)은 그 일측벽(11a)이 실린더핀(2)(2')을 고정하는 브라켓(4)의 일측면(4a)에 접하고 타측벽(11b)은 제1실린더핀(2)에 동시에 접할 수 있는 구조를 가지며, 휠요오크(10)의 예각회전시 상기 예각회전요홈(12)은 그 일측벽(12a)이 제1실린더핀(2)에 접하고 타측벽(12b)이 제2실린더핀(2')에 동시에 접할 수 있는 구조를 가지며, 휠요오크(10)의 직각회전시, 상기 직각회전요홈(13)은 그 일측벽(13a)이 제1실린더(2)에 접하고 타측벽(13b)이 브라켓(4)의 타측면(4b)에 동시에 접할 수 있는 구조를 갖는다.The straight traveling recess 11 has one side wall 11a in contact with one side 4a of the bracket 4 fixing the cylinder pins 2, 2 'and the other side wall 11b has a first cylinder pin ( 2) has a structure that can be in contact with at the same time, the acute rotation groove 12 during the acute rotation of the wheel yoke 10 has one side wall (12a) in contact with the first cylinder pin (2) and the other side wall (12b) It has a structure that can be in contact with the second cylinder pin (2 ') at the same time, when the right angle rotation of the wheel yoke 10, the right side rotation groove 13 has one side wall (13a) in contact with the first cylinder (2) The other side wall 13b has the structure which can contact the other side surface 4b of the bracket 4 simultaneously.
이와같은 구조를 갖는 본 고안에 따른 휠요오크의 구조를 이하에 상세히 설명한다.The structure of the wheel yoke according to the present invention having such a structure will be described in detail below.
직진주행시, 실린더핀(2)은 직진주행요홈(11)의 측벽(11b)에 접촉하여 휠요오크(10)의 반시계방향으로의 타이어(T)의 요동을 방지하고 브라켓(4)의 측면(4a)에 직진주행요홈의 타측벽(11a)이 접촉하여 시계방향으로의 타이어(T)의 요동을 방지하므로서 타이어는 좌우요동없이 직진주행하게 되고 종래의 직진주행요홈보다 실린더핀(2)의 작동이 원활하게 되며 그 구조를 보다 단순하게 하여 작업성을 향상시켰다. 여기서 측벽(11a)는 0도 위치를 유지시키는 역할과 타이어(T)가 시계방향으로 요동하는 힘을 잡아주는 2가지 역할을 수행한다.When driving straight, the cylinder pin (2) is in contact with the side wall (11b) of the straight traveling groove 11 to prevent the tire T from swinging in the counterclockwise direction of the wheel yoke (10) and the side surface of the bracket (4) ( The other side wall 11a of the straight traveling groove is in contact with 4a) to prevent the tire T from swinging in the clockwise direction, so that the tire travels straight without left and right swing, and the cylinder pin 2 is operated more than the conventional straight traveling groove. This is smooth and the structure is simpler to improve workability. Here, the side wall 11a serves to maintain the 0 degree position and serves to hold the force that the tire T swings clockwise.
예각회전주행시, 실린더핀(2)이 후퇴하여 직진주행요홈(11)에서 이탈하고 회전실린더(14)가 전진하면 휠요오크(10)는 P점을 중심으로 정해진 일정각(θ)으로 회동하고 제1실린더핀(2)이 예각회전요홈(12)의 일측벽(12a)에 접하여 시계방향으로의 타이어(T)의 요동을 방지하고 제2실린더핀(2')의 타측벽(12b)에 접하게 되어 반시계방향으로의 타이어의 요동을 방지하므로 타이어(T)는 좌우요동없이 θ각도로 예각회전주행하게 된다.When driving at an acute angle, the cylinder pin (2) retreats to move away from the straight traveling groove (11), and when the rotating cylinder (14) moves forward, the wheel yoke (10) rotates at a predetermined angle (θ) around the point P and The first cylinder pin 2 is in contact with one side wall 12a of the acute turning recess 12 to prevent the tire T from swinging in the clockwise direction and the other side wall 12b of the second cylinder pin 2 'is in contact with the cylinder pin 2. Since the tire is prevented from shaking in the counterclockwise direction, the tire T is acutely rotated at θ angle without the left and right swing.
여기서 예각회전요홈(12)의 측벽(12b)은 θ각도만큼 위치에서 정지시키는 역할과 타이어(T)의 반시계방향으로 요동하려는 힘을 잡아주는 두가지 역할을 한다.Here, the side wall 12b of the acute rotation groove 12 serves to stop at the position by the angle θ and serves to hold the force to swing in the counterclockwise direction of the tire (T).
직각 회전주행시, 실린더핀(2)(2')에 예각회전요홈(12)에서 이탈하고 회전실린더(14)가 전진하며 휠요오크(10)는 P점을 중심으로 90회전하고 실린더핀(2)이 전진하여 직각회전요홈(13)의 일측벽(13a)에 접하여 시계방향으로의 타이어(T)의 요동을 방지하고 브라켓(4)의 타측면(4b)이 직각회전요홈(13)의 타측벽(13b)에 접하여 반시계방향으로의 타이어(T)의 요동을 방지하고 있으므로 90도 회전된 상태에서 구동을 하더라도 좌우요동없이 주행할 수 있다. 여기서 직각회전요홈(13)의 측벽(13b)은 90회전상태에서 위치를 정지시키는 역할과 타이어가 반시계 방향으로 요동하려는 힘을 잡아주는 두가지 역할을 한다.At right angles of rotation, the cylinder pins (2) (2 ') are separated from the acute turning groove (12), the rotating cylinder (14) is advanced, and the wheel yoke (10) rotates about 90 points and the cylinder pin (2) This advance is in contact with one side wall (13a) of the right angle rotation groove 13 to prevent the tire (T) swing in the clockwise direction and the other side (4b) of the bracket (4) is the other side wall of the right angle rotation groove (13) Since the tire T is prevented from swinging in the counterclockwise direction in contact with 13b, even when driving in a state rotated 90 degrees, the vehicle can travel without left and right swing. Here, the side wall 13b of the perpendicular turning recess 13 serves to stop the position in the 90-rotation state and serves to hold the force of the tire to swing in the counterclockwise direction.
이상과 같이 본 고안에 따른 트랜스퍼크레인의 주행각도 고정용 휠요오크는 돌출단턱부나 보조요홈이 없이 직진주행요홈, 예각회전주행 요홈, 및 직각회전요홈만으로 트랜스퍼크레인의 주행각도 고정을 수행하므로서 휠요오크의 구조가 대단히 간단하게 되어 가공시간이 단축되어 작업 능률 및 생산성이 향상되며 원활한 작동을 할 수 있다는 우수한 장점이 있다.As described above, the wheel yoke for fixing the traveling angle of the transfer crane according to the present invention is fixed to the driving angle of the transfer crane only by the straight traveling groove, the acute turning driving groove, and the right turning groove without the protruding step portion or the auxiliary groove. The extremely simple structure reduces machining time, improving work efficiency and productivity and providing smooth operation.
