상기 차량본체(10)는 견인차에 의해서 철도레일(200)상에서 이동되도록 지지프레임(11)의 하측에 차륜(12)이 설치되어 있고, 상기 지지프레임(11) 상부 일측에는 자체 동력 및 유압력이 형성되는 동력발전겸 유압발생부(13)가 형성되며, 이의 반대측에는 작업자가 작업대(70)로 이동될 수 있도록 승강계단(14)이 형성되어 있다.The vehicle body 10 has a wheel 12 is installed on the lower side of the support frame 11 to be moved on the railway rails 200 by a tow truck, and one side of the upper support frame 11 has its own power and hydraulic force. The power generation and the hydraulic generating unit 13 is formed, the lifting side 14 is formed on the opposite side so that the operator can move to the work table 70.

상기 하부프레임(20)은 상기 차량본체(10)의 상부로 일정간격 이격되게 설치된 것으로, 대략 지지프레임(11)의 넓이에 대응된다.The lower frame 20 is installed to be spaced apart a predetermined distance to the upper portion of the vehicle body 10, approximately corresponds to the width of the support frame (11).

상기 지지대(30)는 상기 차량본체(10)의 상부에 하부프레임(20)을 지지하는 것으로, 이중관형태로 이루어져 상하방향으로 슬라이딩 가능하고, 내측관(31)은 상기 하부프레임(20)의 하부에 고정되며, 외측관(32)은 상기 차량본체(10)의 상부에 결합되어진 것으로 복수개가 설치되어 있다.The support 30 is to support the lower frame 20 on the upper portion of the vehicle body 10, it is made of a double tube form and can slide in the vertical direction, the inner tube 31 is the lower portion of the lower frame 20 It is fixed to, the outer tube 32 is coupled to the upper portion of the vehicle body 10 is provided with a plurality.

또한, 상기 지지대(30)의 관형태는 원형, 삼각, 사각, 오각 또는 그 이상의 다각형으로 형성시킬 수 있으나 사각형상이 가장 바람직하고, 갯수도 4개 또는 6개를 설치하는 것이 가장 안정적이다.In addition, the tubular shape of the support 30 may be formed in a polygonal shape of a circle, a triangle, a square, a pentagon or more, but a quadrangular shape is most preferable, and the number is more stable to install four or six.

상기 승하강실린더(40)는 상기 차량본체(10) 및 하부프레임(20) 사이에 설치되어 상기 하부프레임(20)을 승하강시키는 것으로, 로드(41)단부가 상기 하부프레임(20)의 하면에 고정되고, 이의 반대면이 차량본체(10)에 결합되도록 하는 것이다.The elevating cylinder 40 is installed between the vehicle body 10 and the lower frame 20 to elevate the lower frame 20, and the rod 41 end portion of the lower frame 20 is lowered. It is fixed to, to the opposite side is to be coupled to the vehicle body (10).

즉, 상기 승하강실린더(40)가 전진하게 되면 차량본체(10)에서 지지대(30)에 의해 일정높이에 설치된 하부프레임(20)을 상기 지지대(30)의 외측관에서 내측관이 슬라이딩되면서 상방향으로 이동되도록 함으로서, 하부프레임(20)을 일정높이로 상승시키게 된다.(조가선을 작업할 수 있다.(도 2, 도 5참고))That is, when the elevating cylinder 40 is advanced, the inner frame is slid from the outer tube of the support 30 to the lower frame 20 installed at a predetermined height by the support 30 in the vehicle body 10. By moving in the direction, the lower frame 20 is raised to a certain height. (The rough line can be worked. (See FIGS. 2 and 5))

상기 상부프레임(50)은 상기 하부프레임(20)의 상부에 설치되고, 회전지점을 중심으로 상기 차량본체(10)의 폭방향으로 회전되도록 하는 것이다.(도 4, 도 6참고)The upper frame 50 is installed on the upper portion of the lower frame 20, so as to rotate in the width direction of the vehicle body 10 around the rotation point (see Fig. 4, 6).

상기 회전수단(60)은 상기 하부프레임(20)과 상부프레임(50) 사이에 설치되어 상기 상부프레임(50)을 회전시키는 것으로, 상기 하부프레임(20) 상에 설치되고, 외주면에 기어부(61a)가 형성되어진 링 형태의 회전링베어링(slewing ring bearing)(61)의 내경에 상부프레임(50)에서 돌출된 회전축(51)을 결합하고, 유압모터(62)의 구동력을 전달받는 감속기(reducer)(63)의 단부에 형성된 피니언(63a)을 상기 회전링베어링(61)의 기어부(61a)에 이맞물림시켜 회전되도록 하는 것이다.The rotating means 60 is installed between the lower frame 20 and the upper frame 50 to rotate the upper frame 50, is installed on the lower frame 20, the gear portion (on the outer peripheral surface ( Gear reducer (61a) is coupled to the rotating shaft 51 protruding from the upper frame 50 to the inner diameter of the ring-shaped slewing ring bearing 61 is formed, and receives the driving force of the hydraulic motor 62 ( The pinion 63a formed at the end of the reducer 63 is engaged with the gear portion 61a of the rotary ring bearing 61 to rotate.

즉, 상기 회전수단(60)에 의해 하부프레임(20)에서 상부프레임(50)이 차량본체(10)의 폭방향으로 회전시켜 철도레일(200)에 일정간격 이격되어져 설치된 전신주(210)의 각종 지지물 등을 설치 및 보수할 수 있는 것이다.(도 7)That is, the upper frame 50 is rotated in the width direction of the vehicle body 10 from the lower frame 20 by the rotating means 60, various kinds of telegraph poles 210 spaced apart at regular intervals on the railway rails 200. The support can be installed and repaired. (FIG. 7)

상기 작업대(70)는 상기 상부프레임(50)의 상부에 설치되고, 승강수단(80)에 의해 일정높이로 상승되어지는 것으로, 발판형태로 이루어지고, 둘레에는 스케어 파이프 등을 이용하여 안전난간(71)을 설치하게 된다.The work table 70 is installed on the upper portion of the upper frame 50, is raised to a predetermined height by the elevating means 80, made in the form of scaffolding, the safety railing using a scare pipe or the like ( 71).

또한, 상기 승강수단(80)은 다수의 링크로 이루어진 펜더그라프부(81)를 유압실린더(82)로 절첩가능하게 설치한 것으로, 상기 펜더그라프부(81)는 중간힌지점(a)을 중심으로 절첩가능한 제1엑스바(81a) 및 제2엑스바(81b)의 결합되는 단부에 힌지핀(b)으로 연결하도록 하는 것이다.In addition, the elevating means 80 is to be installed to fold the fender graph portion 81 consisting of a plurality of links to the hydraulic cylinder 82, the fender graph portion 81 is centered on the intermediate hinge point (a) It is to be connected by the hinge pin (b) to the coupled end of the first X bar 81a and the second X bar 81b, which are collapsible.

즉, 상기 펜더그라프부(81)의 엑스바는 복수개 설치하여 작업대(70)의 높이를 임의로 조절할 수 있으나 전신주 등을 감안할 때 제1엑스바(81a)와 제2엑스바(81b)를 결합시켜 펼쳐진 높이만으로도 작업할 수 있는 높이는 충분할 것이다.(도 8, 도 9참고)That is, the height of the worktable 70 can be arbitrarily adjusted by installing a plurality of x bars of the fender graph unit 81, but considering the telegraph pole, the first x bar 81a and the second x bar 81b are coupled to each other. The height to work with the unfolded height will be sufficient (see Figs. 8 and 9).

본 발명에 따른 작용을 상세히 설명하면 다음과 같다.Referring to the operation according to the invention in detail as follows.

견인차에 의해 작업장소로 본 발명에 따른 전철보수용 고소작업차(100)를 이동시킨 상태에서 전차선 등의 가설, 전신주의 각종 지지물을 설치 및 교환 등의 보수작업을 수행하게 된다.In the state of moving the train repair aerial work vehicle 100 according to the present invention to a work place by a tow truck is to perform repair work such as installation and replacement of various supports, such as tram lines, telegraph poles.
