At this time, the safety work net must be installed before the maintenance work is performed.

종래에는 상기 보호망을 2-3명의 작업자에 의해서 고소지역으로 운반하고 이를 크레인 하부에 설치및 철거하여 왔다.Conventionally, the protection net has been transported to a height area by 2-3 workers, and it has been installed and dismantled under the crane.

그러나, 상기 종래의 설치 및 철거방법에 있어서는 중량의 안전망을 정비점검시 매번 운반해야 하는 불편함과 고소지역으로의 운반및 고소지역에서의 설치작업에 따른 재해발생 및 작업시간과다등의 문제점에 따르게 된다.However, in the conventional installation and dismantling method, it is necessary to avoid the inconvenience of having to carry the safety net of weight every time during maintenance inspection, and the problems such as the occurrence of disaster and excessive working time due to transportation to the aerial area and installation work in the aerial area. do.

따라서, 본 고안은 기존의 천정크레인에 설치되어 크레인자체이동으로 안전망을 설치 및 철거하도록 구성된 천정크레인 안전보호망 설치장치를 제공하므로서 안전망 설치시 재해방지 및 설치시간을 단축하고자하는 것이다.Accordingly, the present invention is to provide a ceiling crane safety protection net installation device is installed in the existing ceiling crane to install and dismantle the safety net by moving the crane itself to reduce the disaster prevention and installation time when installing the safety net.

이하, 본 고안을 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings.

본 고안은, 제1도 및 제2도에 나타난 바와같이, 유지부(10), 롤링부(20) 및 구동장치(30)로 대별되는데, 상기 유지부(10)는 횡행레일(103)상에서 이동되는 천정크레인(100)의 횡행그라브(101)에 고정되어있는 보조서포트(12)및 천정크레인(100)이 이동되는 방향에서 볼때 횡방향으로 핸드레일(102)의 소정위치에서 회전가능하게 유지되는 롤러견인축(11)을 포함한다.The present invention, as shown in Figs. 1 and 2, is roughly divided into a holding portion 10, a rolling portion 20 and a driving device 30, the holding portion 10 on the transverse rail 103 The auxiliary support 12 and the ceiling crane 100 fixed to the transverse grab 101 of the ceiling crane 100 to be moved are rotatably held at a predetermined position of the handrail 102 in the transverse direction when viewed from the moving direction. And a roller towing shaft 11 to be used.

상기 롤러견인축(11)의 양단부는 천정크레인(100)의 핸드레일(102)에 용접등에 의해서 고정된 플레이트(13)에 장착된 링크벨트 베어링(14)에 끼워지고, 양단부중의 한쪽단부에는 롤러견인축(11)의 회전력을 부여하는 구동장치(30)와 구동맞물림되는 스프라켓 또는 기어(15)등이 형성되어있으며, 또한, 롤러견인축(11)의 중앙에서 소정거리를 갖는 위치에 후크(17)를 갖는 두 개의 와이어로프(16)가 롤러 견인축(11)의 회전시 풀리거나 또는 감기도록 고정되어있다.Both ends of the roller towing shaft 11 are fitted to a link belt bearing 14 mounted on a plate 13 fixed to the handrail 102 of the ceiling crane 100 by welding or the like, and on one end of both ends thereof. A sprocket or gear 15 for driving engagement with a drive device 30 for imparting rotational force of the roller towing shaft 11 is formed, and is hooked at a position having a predetermined distance from the center of the roller towing shaft 11. Two wire ropes 16 having 17 are fixed to unwind or wind upon rotation of the roller pull shaft 11.

상기 와이러로프(16)의 후크(17)가 끼워지도록 고정홈(22)이 형성된 플랜지(23)은 양단부에서 갖는 상기 롤링부(20)의 롤러(21)는 축(24)에 볼트등으로 연결된 롤러지지구(25)에 의해서 상기 유지부(10)의 보조서포트(12)에 운동즉, 상, 하 운동가능하게 지지되는데 (제3도의 화살표방향), 상기 보조서포트(12)에 셔클(26)을 끼워 롤러지지구(25)가 소정범위내에서 운동하도록 해주는 것이 바람직하다.The roller 21 of the rolling part 20 has a flange 23 having a fixing groove 22 formed at both ends thereof so that the hook 17 of the wire rope 16 is fitted with a bolt or the like on the shaft 24. It is supported by the roller support 25 connected to the auxiliary support 12 of the holding portion 10, that is, to move up and down (in the direction of the arrow in FIG. 3), the shuffle ( It is preferable that the roller support 25 be inserted into the roller support 25 so as to move within a predetermined range.

또한, 상기 축(24)은 롤로지지구(25)와 일체로 형성시킬수도 있다.In addition, the shaft 24 may be formed integrally with the roll support 25.

상기 롤러(21)의 양단부에 형성된 플랜지(23)사이에는 롤러(21)가 천정크레인(100)의 횡행레일(103)상에서 운동하는 경우 풀리거나 또는 감기도록 안전망(27)의 일단이 상기 축(24)방향으로 고정되어있으며 상기 안전망(27)의 타단은 안전망(7)설치시 천정크레인(100)의 크레인새들사이드(104)상부에 부착된 걸림고리(28)에 끼워지게 된다.Between the flanges 23 formed at both ends of the roller 21, one end of the safety net 27 is unwound or wound when the roller 21 moves on the transverse rail 103 of the ceiling crane 100. The other end of the safety net 27 is fitted in the hook 28 attached to the crane saddle side 104 of the ceiling crane 100 when the safety net 7 is installed.

한편, 상기 구동장치(30)는, 제2도 및 제3도에 나타난 바와같이, 역회전가능한 유압모터(31), 유압모터(32) 및 구동스프라켓 또는 기어(33)등을 포함하고 이 구동스프라켓(33)은 체인(34)에 의해서 상기롤러견인축(11)의 스프라켓(15)과 구동연결되고, 상기 구동기어(33)을 사용하는 경우에는 구동기어(33)가 룰러견인축(11)의 기어(15)와 구동맞물림되므로서, 롤러견인축(11)에 구동력을 부여하게 된다.On the other hand, the drive device 30 includes a hydraulic motor 31, a hydraulic motor 32, a drive sprocket or a gear 33, and the like, which can be reversely rotated, as shown in FIGS. 2 and 3. The sprocket 33 is connected to the sprocket 15 of the roller towing shaft 11 by a chain 34, and in the case of using the drive gear 33, the drive gear 33 is the ruler towing shaft 11. By driving engagement with the gear 15 of the (), the driving force is applied to the roller towing shaft (11).

또한, 천정크레인(100)의 핸드레일(102)에는 리미트스위치(35)가 부착되어 롤러(21)가 제3도에 나타난 상부위치(실선부분)로 복귀되는 경우 구동스프라켓 또는 구동기어(33)에 연결된 전원을 차단하여 롤러견인축(11)의 회전을 정지시키게 된다.In addition, when the roller 21 is returned to the upper position (solid line part) shown in FIG. 3 by the limit switch 35 attached to the handrail 102 of the ceiling crane 100, the driving sprocket or the driving gear 33 The power is connected to stop the rotation of the roller towing shaft (11).

상기 롤러견인축(11)의 회전력을 부여하는 또다른 수단으로는 제1도 및 제2도에 나타난 바와같이, 롤러 견인축(11)에 핸들(19)을 구비하여 이 핸들(19)을 회전시켜주므로써 안전망설치작업을 수행할 수 있는데, 이때에는 상기 롤러견인축(11)에는 스프라켓 또는 기어(15)등을 형성하고 핸드레일(102)에는 스토퍼키이(18)를 설치하여 상기 스프로켓 또는 기어(15)에 스토퍼키이(18)를 걸어주므로서 롤러견인축(11)의 회전을 제어하게 된다.As another means for imparting the rotational force of the roller towing shaft 11, as shown in FIGS. 1 and 2, the handle 19 is provided on the roller traction shaft 11 to rotate the handle 19. By doing so, the safety net can be installed. At this time, the sprocket or gear 15 is formed on the roller towing shaft 11 and the stopper key 18 is installed on the handrail 102 to install the sprocket or gear. Rotation of the roller towing shaft 11 is controlled by applying the stopper key 18 to 15.

상기와 같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다. 제1도및 제3도에 나타나 바와같이, 천정크레인 (100)를 우측으로 이동시킨 다음 유압모터(31)를 구동시켜 롤러견인축(11)을 회전시켜주므로서 롤러견인축(11)에 고정된 와이어로프(16)가 풀리게 되어 롤러(1)가 횡행레일(103)상부에 안착된 다음 안전망(27)의 타단을 크레인(100)의 새들사이드(104)에 형성된 걸림고리(28)에 연결한후 천정크레인(100)을 좌측으로 이동시킴으로서 안전망(27)의 설치작업이 완료된다.Referring to the operation and effects of the present invention configured as described above are as follows. As shown in FIGS. 1 and 3, the ceiling crane 100 is moved to the right, and then the hydraulic motor 31 is driven to rotate the roller towing shaft 11 to fix the roller towing shaft 11. The wire rope 16 is released and the roller 1 rests on the transverse rail 103 and then connects the other end of the safety net 27 to the hook 28 formed on the saddleside 104 of the crane 100. After the ceiling crane 100 is moved to the left, the installation work of the safety net 27 is completed.

물론, 안전망 철거작업을 상기 설치작업의 역순으로 행하면 된다.Of course, the safety net removal work may be performed in the reverse order of the installation work.

상기한 바와같이, 본 고안은 별도의 인력이 필요없이 신속하게 안전망을 설치 및 철거할 뿐만 아니라 고소작업의 안전재해를 방지하며 정비시간단축으로 생산성향상을 높일 수 있는 현저한 효과가 있는 것이다.As described above, the present invention has a remarkable effect of quickly installing and dismantling a safety net without the need for a separate manpower, as well as preventing safety accidents at height work and improving productivity by reducing maintenance time.
