Description

안테나 지지장치{Antenna support apparatus}Antenna support apparatus

본 발명은 기지국용 안테나 지지장치에 관한 것으로, 특히 간단한 틸팅 구조에 의해 기지국용 안테나의 전파 지향 경사 각도를 정밀하게 조절하면서도 쉽고 안정적으로 조절할 수 있도록 한 기지국용 안테나 지지장치에 관한 것이다.The present invention relates to an antenna support device for a base station, and more particularly, to an antenna support device for a base station that can easily and stably adjust the radio wave directing inclination angle of an antenna for a base station by a simple tilting structure.

현재 이동통신의 발달이 가속화되어 가고 있는 상황에서 통화가능지역의 확대를 위해서 신속한 기지국 안테나 설치 뿐만 아니라 설치후에도 유지보수 및 전파환경의 최적화작업이 지속적으로 수행 하게 된다.In the current situation where the development of mobile communication is accelerating, in order to expand the callable area, not only the rapid installation of the base station antenna but also the maintenance and optimization of the radio wave environment are continuously performed after installation.

이러한 이동통신 기지국용 안테나는 그 한 예로 등록실용신안 20-0442822(이동통신 기지국용 안테나)에 나타나 있는데, An example of such an antenna for a mobile communication base station is shown in Registered Utility Model 20-0442822 (Antenna for a mobile communication base station),

안테나(10)의 상부 및 하부는 클램프(20)를 매개로 지지대(2)에 설치되며, 이 클램프(20)에는 클램프(20)를 조였다가 풀 수 있는 방위각 조절용 볼트(22)가 설치되고, 상부의 클램프(20)에는 경사각 조절용 볼트(32)로 하여 링크 이동을 가져오는 링크절(30)이 설치되는 구성을 가진다.The upper and lower portions of the antenna 10 are installed on the support 2 through the clamp 20, and the azimuth adjustment bolt 22 that can tighten and loosen the clamp 20 is installed in the clamp 20, The upper clamp 20 has a configuration in which a link section 30 is installed to bring the link movement by using the inclination angle adjustment bolt 32 .

즉, 안테나(10)의 경사각의 조절은 경사각 조절용 볼트(32)를 풀고 링크절(30)을 접었다 폈다하면서 이루어지고, 방위각조절은 지지대(2)로부터 방위각 조절용 볼트(22)를 풀어 원하는 위치로 회전시킨 후 다시 고정하여 이루어진다.That is, the adjustment of the inclination angle of the antenna 10 is made by loosening the inclination angle adjustment bolt 32 and folding and unfolding the link section 30, and the azimuth adjustment is performed by loosening the azimuth adjustment bolt 22 from the support 2 to the desired position. It is rotated and then fixed again.

따라서, 작업자가 방위각 및 경사각 조절용 볼트(22)(32)를 풀고 지상의 원하는 목표지점을 향하여 안테나(10)를 회전시키거나 상하방향으로 이동시켜 각도 조절이 이루어지게 된다.Accordingly, the operator loosens the bolts 22 and 32 for adjusting the azimuth and inclination angles and rotates the antenna 10 toward a desired target point on the ground or moves it up and down to adjust the angle.

그런데, 이러한 종래의 기술에 의하면, 경사각 조절은 링크절(30)의 펼침 정도에 의해 결정되고, 그 펼침 상태를 경사각 조절용 볼트(32)에 의해 고정하게 되는데, 시간이 경과되면서 안테나(10)의 자체 무게에 의해 하측방향으로 기울어지는 하중이 경사각 조절용 볼트(32)에 계속 가해지게 되면, 경사각 조절용 볼트(32)가 헐거워지면서 안테나(10)의 기울임 각도가 매우 커지게 된다.However, according to this conventional technique, the angle of inclination adjustment is determined by the degree of unfolding of the link section 30, and the unfolded state is fixed by the bolt 32 for adjusting the angle of inclination. When the load inclined downward by its own weight is continuously applied to the inclination angle adjustment bolt 32, the inclination angle adjustment bolt 32 loosens and the inclination angle of the antenna 10 becomes very large.

즉, 안테나(10)가 초기 설정된 방향을 지향하지 않고, 하측으로 기울어지면서 원하는 않는 방향을 향하게 됨으로써 자칫 통신 장애 등의 문제점을 가져오게 된다. That is, the antenna 10 does not face an initially set direction, but rather faces an undesired direction while tilting downward, thereby causing problems such as communication failure.

이러한 문제점을 해결하기 위해서 종래의 기술에 의하면 등록특허 10-2025583(안테나 각도조절 장치)에서는 각도조절용 관통구(114)에 각도조절용 핀(140)을 삽입시킴으로써 안테나의 설치각도를 견고하게 유지할 수는 있으나, 제1 회동부재(110)과 제2회동부재(130)에 다수의 핀공을 구비해야 할 뿐만아니라 핀공의 수량이 제한 될 수 밖에 없으므로 각도조절을 세밀하게 할 수 없는 문제점이 있으며, 각도조절 시 상기 등록실용신안 20-0442822(이동통신 기지국용 안테나)에서 처럼 각 링크절마다 볼트를느슨하게 풀어서 각도조절 후에 다시 조이는 작업을 해야 하는 번거러움이 있으며, 더구나 최근 구축되고 있는 5G안테나들은 25kg 이상 무거워서 각도 조절시 한사람의 작업자가 무거운 안테나의 각도를 손으로 유지하고 있는 상태에서 링크절의 볼트를 조작하거나 각도조절용 핀을 삽입하는 작업을 하는 데 문제점이 있다.In order to solve this problem, according to the prior art, registered patent 10-2025583 (antenna angle adjustment device) inserts the angle adjustment pin 140 into the angle adjustment through-hole 114 to firmly maintain the installation angle of the antenna. However, the first rotation member 110 and the second rotation member 130 must be provided with a plurality of pin balls, as well as the number of pin balls is limited, so there is a problem that the angle adjustment cannot be made precisely, and the angle adjustment is not possible. As in the registered utility model 20-0442822 (Antenna for mobile communication base station), there is a hassle of loosening the bolts for each link section and re-tightening them after adjusting the angle. When adjusting, there is a problem in that one operator operates the bolt of the link section or inserts the angle adjustment pin while maintaining the angle of the heavy antenna by hand.

또한, 이와 같은 각도조절작업은 안테나의 상부에 위치하고 있으므로 작업자가 상부에 올라가서 작업을 해야하는데 여러가지 조작에 의한 각도조절 작업은 작업자의 안전을 위협할 수 있는 문제점이 있다.In addition, since such an angle adjustment operation is located on the upper part of the antenna, the operator has to climb to the upper part to work, but the angle adjustment operation by various manipulations has a problem that may threaten the safety of the operator.

본 발명은 상기의 문제점을 해결하기 위하여, 안테나 각도 조절 시 각 링크절의 볼트를 느슨하게 해제하거나 각도고정용 조절핀을 삽입하는 등 여러가지 조작을 하지 않고 간단한 조작으로 안전하게 각도조절을 하면서도 안테나의 각도를 견고하게 유지하도록 하는 안테나 지지장치를 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention securely adjusts the angle of the antenna while safely adjusting the angle with a simple operation without various manipulations such as loosening the bolt of each link joint or inserting an angle fixing adjustment pin when adjusting the angle of the antenna. An object of the present invention is to provide an antenna support device to maintain the

도1은 본 발명에 의한 안테나 지지장치의 구조를 보인 도로서 상하방향으로 세워진 하부 지지대(10)의 상측에 상부고정클램프(300)가 고정되고 상기 상부고정클램프(300)의 전방으로 돌출된 부위에 제2회동체(600)의 일단이 회전가능하게 결합되고 타단은 제1회동체(500)의 일단에 회전가능하게 결합되며, 제1회동체(500)의 타단은 안테나(100)의 후면 상측에 고정된 상부브라켓(120)과 회전가능하게 결합된다. 그리고 안테나(100)의 후면 하측에는 하부브라켓(110)이고정되며 상기 하부브라켓(110)은 지주에 고정되는 하부고정클램프(200)의 전방에 돌출된 부위와 회전가능하게 결합된다.1 is a road showing the structure of an antenna support device according to the present invention, in which an upper fixing clamp 300 is fixed to the upper side of a lower support 10 erected in the vertical direction, and a portion protruding forward of the upper fixing clamp 300 One end of the second rotating body 600 is rotatably coupled to one end and the other end is rotatably coupled to one end of the first rotating body 500 , and the other end of the first rotating body 500 is the rear surface of the antenna 100 . It is rotatably coupled to the upper bracket 120 fixed to the upper side. And the lower bracket 110 is fixed to the lower rear side of the antenna 100, and the lower bracket 110 is rotatably coupled to a portion protruding from the front of the lower fixing clamp 200 fixed to the post.

그리고 상기 제1회동체(500)에는 측방향으로 형성된 홀에 제1힌지구(510)가 회전가능하게 결합되며, 상기 제2회동체(600)에는 측방향으로 형성된 홀에 제2힌지구(610)이 회전가능하게 결합되며, 상기 제1힌지구(510)와 제2힌지구(610)에는 각각 관통홀이 형성되어 장볼트 형태의 간격 조절구(700)가 상기 제1힌지구(510)과 제2힌지구(610)을 관통하여 회전가능하게 결합된다.And a first hinge member 510 is rotatably coupled to the hole formed in the lateral direction in the first rotating body 500, and the second hinge member (510) in the hole formed in the lateral direction in the second rotating body 600 610 is rotatably coupled, and the first hinge 510 and the second hinge 610 have through-holes formed therein, so that the long bolt-shaped gap adjusting sphere 700 is connected to the first hinge 510 . ) and the second hinge portion 610 is rotatably coupled through.

이때, 상기 제2힌지구(610)에는 나사산이 형성되어 장볼트 형태로 나사산이 형성된 간격조절구(700)가 상기 제2힌지구(610)를 관통시에 나사산에 의해 걸리는 상태가 되고 회전하는 만큼 관통되면서 회전하지 않으면 관통되지 않는 구조로 형성된다. 상기 제2힌지구(610)를 관통한 간격조절구(700)는 상기 제1힌지구(510)를 관통한 끝단에 상기 제1힌지구(510)의 전.후에 걸림턱이 형성되어 상기 간격조절구(700)가 제1힌지구(510)의 내측에서 회전하가능한 상태에서 전후로 관통되지 않고 고정되도록 형성된다.At this time, a screw thread is formed in the second hinge member 610, and the gap adjusting member 700 having a screw thread in the form of a long bolt enters a state of being caught by a screw thread when passing through the second hinge member 610 and rotates. It is formed in a structure that does not penetrate if it does not rotate while being penetrated as much as possible. The gap adjusting member 700 passing through the second hinge member 610 is formed with a locking protrusion before and after the first hinge member 510 at the end passing through the first hinge member 510 to form the gap. The adjustment member 700 is formed so as to be fixed without being penetrated back and forth in a rotatable state inside the first hinge member 510 .

따라서, 상기 간격조절구(700)를 스페너 또는 임팩 등의 공구를 이용하여 회전시키면 제1힌지구(510)와 제2힌지구(610)간의 간격이 조절되어 상기 제1회동체(500)와 제2회동체(600)가 펼쳐지거나 접혀지면서 안테나(100)의 경사각도가 조절되는 것이다.Therefore, when the spacing adjusting member 700 is rotated using a tool such as a spanner or an impactor, the interval between the first hinge member 510 and the second hinge member 610 is adjusted, and the first rotating body 500 and As the second rotating body 600 is unfolded or folded, the inclination angle of the antenna 100 is adjusted.

이와 같이 간격조절구(700)를 회전시키기만 하면 안테나(100)의 경사각이 조절되는 구조로서, 상부브라켓(120)과 제1회동체(500), 제2회동체(600) 그리고 상부고정클램프(300)가 순차적으로 연결되는 부위가 회전가능하게 결합되면서 다수 형성되는 링크절들은 안테나(100)를 흔들림 없이 견고하게 고정시키기 위해서 평상시에 링크절들을 볼트와 너트로 강하게 압박하여 고정시켜 놓은 상태인데, 전파지향각의 수정을 위한 안테나의 각도조절시 이러한 링크절들의 압박력을 해제하지 않아도, 스페너 및 임팩 등의 공구를 활용해서 간격조절구(700)을 쉽게 회전시켜서 안테나(100)의 경사각도를 쉽고 안전하게 조절할 수 있는 것이다. In this way, the inclination angle of the antenna 100 is adjusted only by rotating the spacing adjusting member 700 , and the upper bracket 120 , the first rotating body 500 , the second rotating body 600 , and the upper fixing clamp are used. (300) The sequentially connected parts are rotatably coupled to form a plurality of link nodes in order to firmly fix the antenna 100 without shaking. , when adjusting the angle of the antenna for the correction of the radio wave direction, without releasing the pressing force of these link sections, the inclination angle of the antenna 100 can be adjusted by easily rotating the spacing adjusting tool 700 using a tool such as a spanner and an impactor. It is easy and safe to control.
