이하, 본 발명의 구체적인 실시 예를 첨부 도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

먼저, 본 발명의 일 실시 예에 따른 보일러 하부커버 취외장치의 구성을 도 1 내지 도 5를 통해 살펴보면, 보일러(100)의 하부커버(110)에 형성된 볼트홀(111)에 삽입이 가능하도록 다수의 체결구(11)가 수직방향으로 세워진 상태로 구성되어져 있는 상부플레이트(10)와, 상기 상부플레이트(10)를 높이조절 가능하도록 지지하는 높이조절대(20)와, 상기 높이조절대(20) 하부에 결합되어져 있는 하부받침대(30)와, 상기 하부받침대(30) 하부에 이동이 용이하도록 구비된 이동바퀴(40)로 이루어짐을 확인할 수 있다.1 to 5, a plurality of bolt holes 111 are formed in the lower cover 110 of the boiler 100 so as to be inserted into bolt holes 111 formed in the lower cover 110 of the boiler 100, A height adjuster 20 for supporting the upper plate 10 so as to be adjustable in height and a height adjuster 20 for adjusting the height of the upper plate 10, A lower pedestal 30 coupled to a lower portion of the lower pedestal 30 and a moving wheel 40 provided at a lower portion of the lower pedestal 30 to facilitate movement thereof.

특히, 높이조절대(20)는 상부플레이트(10) 저면에 결합되어져 있는 조절스크류(13)의 삽입이 가능하도록 삽입공(21)이 상부에 형성되어져 있으며, 상기 높이조절대(20) 상부에는 조절스크류(13)와 나사결합되어져 있는 조절손잡이(22)가 안착 구성되어져 있으며, 상기 조절손잡이(22)의 회전을 가이드하기 위한 가이드링(23)이 조절스크류(13)에 끼워져 구비된다.Particularly, the height adjuster 20 is formed on the upper portion of the height adjuster 20 so that the adjusting screw 13 coupled to the bottom of the upper plate 10 can be inserted. And a guide ring 23 for guiding the rotation of the adjustment knob 22 is fitted in the adjustment screw 13. The adjustment knob 22 is screwed with the adjustment screw 13. [

또한, 체결구(11) 하부에는, 체결구(11)의 볼트홀(111) 삽입시 하부커버(110)가 상부플레이트(10)와 일정 높이로 간격 유지가 이루어질 수 있도록 간격유지봉(12)이 구성되어지게 된다.The lower cover 110 may be spaced apart from the upper plate 10 at a predetermined height when the bolt hole 111 of the fastener 11 is inserted into the lower portion of the fastener 11. [ .

한편, 도 6은 본 발명의 응용 예에 따른 구조를 나타낸 것으로서, 높이조절대(20)의 삽입공(21) 내부에는 조절스크류(13)를 일정 탄성력으로 지지하는 탄성스프링(24)이 구성됨이 바람직하다.FIG. 6 shows a structure according to an application example of the present invention. Inside the insertion hole 21 of the height adjuster 20, an elastic spring 24 for supporting the adjusting screw 13 with a predetermined elastic force is formed. desirable.

이와 같은 구성을 이루는 본 발명 취외장치를 이용한 보일러 하부커버의 취외작업과정을 도 7 내지 도 9를 통해 살펴보기로 한다.7 to 9, a description will be given of the operation of the lower cover of the boiler using the present invention.

먼저, 본 발명의 취외장치를 작업이 이루어질 보일러(100)의 하부커버(110) 설치위치 하부로 이동시킨 상태에서 상부플레이트(10)를 상승시켜서 하부커버(110)를 받쳐주도록 하게 된다.First, the upper plate 10 is raised to support the lower cover 110 in a state in which the operating device of the present invention is moved to a lower position of the installation position of the lower cover 110 of the boiler 100 to be operated.

즉, 이때에는 도 7에서와 같이 하부커버(110) 고정을 위해 결합되어져 있는 다수의 결합볼트(112) 중 취외장치에 구비된 4개의 체결구(11)가 삽입가능하도록 대응되는 위치의 결합볼트(112)를 먼저 분리시킴으로서 도 8에서와 같이 볼트홀(111)이 노출되도록 하게 된다.That is, at this time, as shown in FIG. 7, among the plurality of coupling bolts 112 that are coupled to fix the lower cover 110, four coupling holes 11 provided in the outboard device are inserted, So that the bolt hole 111 is exposed as shown in FIG.

이후, 작업자가 조절손잡이(22)를 일방향으로 돌려서 회전시킴으로서 조절스크류(13)와의 작용에 의해 상부플레이트(10)가 상승되어지게 되면서, 도 9에서와 같이 상기 노출된 볼트홀(111)에 체결구(11)가 삽입되어지게 된다.Thereafter, the operator rotates the adjusting knob 22 in one direction to rotate the upper plate 10 by the action of the adjusting screw 13, so that the upper plate 10 is fastened to the exposed bolt hole 111 as shown in FIG. So that the sphere 11 is inserted.

이때, 하부커버(110)는 간격유지봉(12)에 상부플레이트(10)와 일정 이격간격이 유지됨으로서 하부커버(110)에 연결 구비된 안내파이프(113)와의 간섭 발생이 방지되어질 수 있게 된다.At this time, the lower cover 110 is spaced apart from the upper plate 10 by a predetermined distance from the gap maintaining rods 12, so that interference with the guide pipes 113 connected to the lower cover 110 can be prevented .

또한, 도 6에서와 같이 탄성스프링(24)이 구성된 응용 예의 경우는 탄성스프링(24)의 탄성력에 의해 조절스크류(13)에 상승력이 작용되어짐으로서 보다 안정적인 상부플레이트(10)의 상승 구동이 이루어지게 됨을 알 수 있다.6, in the case of the application example in which the elastic spring 24 is constituted, since the upward force is exerted on the adjusting screw 13 by the elastic force of the elastic spring 24, the upward driving of the upper plate 10 is performed more stably .

이와 같이 체결구(11)에 의해 안정적인 지지가 이루어지는 상태에서 나머지 결합볼트(112)를 분리시키게 되면 하부커버(110)는 보일러(100)와의 결합상태가 완전히 해제되어짐으로서 상부플레이트(10)의 간격유지봉(12)에 의해 받쳐지는 상태를 이루게 된다.When the remaining coupling bolts 112 are separated in a state of being stably supported by the fasteners 11 as described above, the lower cover 110 is completely disengaged from the boiler 100, So that it is supported by the holding rod 12.

이러한 상태에서 작업자가 조절손잡이(22)를 반대방향으로 회전시키게 되면 조절스크류(13)와의 작용에 의해 상부플레이트(10)의 하강 구동이 이루어짐으로서 하부커버(110)가 함께 하강되어짐으로서 안전하고 효율적인 하부커버(110) 취외작업이 이루어지게 됨을 알 수 있다.In this state, when the operator rotates the adjusting knob 22 in the opposite direction, the lower plate 110 is lowered together with the downward movement of the upper plate 10 by the action of the adjusting screw 13, It can be seen that the operation of the lower cover 110 is completed.

그리고, 취외 후 다시 하부커버(110)를 보일러(100)에 장착시키고자 하는 경우에도 본 발명의 취외장치를 이용하여 상기와 반대순서로 작업을 실시함으로서 안전한 작업이 이루어질 수 있게 된다.Also, in the case where the lower cover 110 is to be mounted on the boiler 100 again after being taken out of the boiler 100, it is possible to perform a safe operation by carrying out the operation in the reverse order to the above using the operating device of the present invention.

따라서, 본 발명의 취외장치는 중량물인 하부커버(110)의 취외작업은 물론 설치작업시 1인의 작업자가 보다 효과적이면서 안전하게 작업을 실시할 수 있게 되어 작업효율성 및 안전성을 극대화하는 이점을 나타내게 된다.
Accordingly, the present invention provides an advantage of maximizing work efficiency and safety by allowing a single worker to work more effectively and safely, as well as to work outdoors of the lower cover 110 which is a heavy article.
