본 고안은 아파트등과 같은 고층건물의 옥상바닥면에서 이동되게 설치하여 공사시 각종 장비나 입주시 이사짐등을 운반하도록 된 화물용 곤도라의 안전장치에 관한 것으로, 특히 케이지 승하강시 상승제한에 있어서 곤도라의 아암에 케이지가 충돌되는 사고를 방지할 목적으로 안출된 것이다.The present invention relates to a safety device of a cargo gondola, which is installed to move from a rooftop floor of a high-rise building such as an apartment, to carry various equipment during the construction and moving, especially in the case of lifting and falling cages. It is designed to prevent an accident of a cage colliding with the arm of the arm.
먼저 종래의 곤도라의 안전장치를 살펴보면, 도면 제 1 도 및 제 2 도에서와 같이 중심에서 양측으로 상호 방향이 다른 나사홈을 가지는 드럼 (100)의 전방에 횡설되어 드럼의 회전에 따라 벨트(V)로 동력전달 회전하는 가이드축(200)의 양측에는 어느일측의 것에 조작편(202)을 가지는 제 1 안내 활파(201)가 각각 설치되고 그 전방에 횡설된 브라켓(300)양측 각각에는 장공(301)을 횡설한 취부대(302)에 볼트로써 횡행위치 조절되는 상한 리미트 스위치(401)와 하한 리미트 스위치(402)를 부설하여서 된 것으로 그 전방의 제 2 안내활차(500)는 제1안내 활차로 부터의 와이어로프(W)를 안내하여 아암선단의 롤러(600)를 따라 케이지(C)에 연결 고정된 상태이다.First, the safety device of the conventional gondola, as shown in Figs. 1 and 2 of the drawings, from the center to both sides of the drum 100 having a mutually different screw grooves in front of the drum 100 is rolled up in accordance with the rotation of the drum (V) On both sides of the guide shaft 200, which is power-driven and rotated, the first guide glide 201 having the operation piece 202 is provided on either side of each of the guide shafts 200, and each of the brackets 300 rolled in front of the guide shaft 200 is provided with a long hole ( The upper limit switch 401 and the lower limit switch 402 which are adjusted in the transverse position by bolts are attached to the mounting table 302 which has laid the 301. The second guide pulley 500 in front of the first guide pulley The wire rope (W) from the guide is fixed to the cage (C) along the roller 600 of the arm tip.
이렇게 구성된 종래의 안전장치는 케이지(C)승하강에 따른 와이어로프(W)를 제1안내활차(201)가 안내시키며, 드럼(100)과 벨트(V)로 연결된 구동력으로 가이드축(200)을 회전시킴으로써 이와 나사결합되는 안내활차(201)를 횡행 이동되지 하고 이에따라 제1안내활차(201)의 저부에 돌설된 조작편(202)이 상 또는 하한 리미트(401) (402)를 작동시켜 곤도라의 과승하강 작동을 중지시키도록 한 것이다.In the conventional safety device configured as described above, the first guide pulley 201 guides the wire rope W according to the cage C lifting and lowering, and the guide shaft 200 is driven by the drum 100 and the belt V. Rotation of the guide pulley 201 is not transversely moved by screwing the operating piece 202 protruding to the bottom of the first guide pulley 201 according to the operation of the upper or lower limit (401) 402 gondola It is to stop the operation of overshooting.
그러나 이는 와이어로프(W)의 오랜 사용으로 인한 늘어남 등으로 최대높이 및 최저높이 위치가 변경되므로써 그때마다 또는 곤도라의 설치현장마다 작동시 운전시험을 하여 상, 하한 리미트 스위치(401) (402)의 위치조정을 하는 작업을 해야만 하는 불편함이 있으며, 특히 곤도라 사용중 인입전원의 역상 발생 (즉 케이지가 상한 위치에 있는데 하강시키려 할때 역상으로 전원이 입력되어 케이지의 상승발생)및 조작선 자체의 쇼트발생, 운전자의 오조작등의 상황발생시 상기의 안전장치에도 불구하고 동작 차단이 이루어지지 않기 때문에 무용지물의 상황이 발생하여 곤도라의 파손 및 안전사고의 위험을 초래케 하는 것으로 중요하게는 과상승에 의한 곤도라아암(A)과 게이지(C)가 충돌되는 안전사고이다.However, this is because the length of the maximum height and the minimum height is changed due to the long use of the wire rope (W), and the operation test is performed every time or every installation site of the gondola, so that the upper and lower limit switches (401) and (402) It is inconvenient to have to adjust the position, especially when the incoming power is reversed during the use of the gondola (that is, when the cage is in the upper position and the power is reversed when the cage is lowered, the cage rises) and the operation line itself is short. In the event of a situation such as an accident or a misoperation of the driver, the operation is not blocked in spite of the above-mentioned safety devices. Therefore, a situation of useless matter occurs, which causes the risk of damage to the gondola and safety accidents. This is a safety accident in which the gondola arm (A) collides with the gauge (C).
따라서, 본 고안은 곤도라 아암과 케이지가 오조작등에 의해 충돌 파손 내지는 안전사고를 유발하는 문제점을 해결하고자 아암의 하부에 리미트 스위치가 부설되는 브라켓과 그 하부에 고정되는 홀더와 홀더내부에 관통안내되는 와이어로프를 관통안내되게 한 작동바 및 작동바를 관통한 하부의 와아이로프상에 상기 작동바를 승강작동시킬 링을 고정시켜서 된 안전장치로 구성되어 케이지와 곤도라 아암선단 사이의 충돌지점에서 직접작용되는 안전장치를 제공하여 어떠한 경우에도 확실하고 안전한 곤도라의 운전이 이루어지게 한 것이다.Therefore, the present invention is to penetrate the inside of the holder and the holder fixed to the bracket and the lower limit of the bracket is installed on the lower part of the arm to solve the problem that the gondola arm and the cage causes a crash or safety accident due to misoperation, etc. It consists of an operating bar that guides the wire rope through and a safety device that secures a ring for lifting and lowering the operating bar on the lower eye rope through the operating bar, which is operated directly at the point of impact between the cage and the gondola arm tip. The provision of the device ensures that the operation of the gondola is assured and safe in any case.
이하에서 이를 양호한 실시예의 첨부도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings of the preferred embodiment as follows.
와이어로프의 늘어남 및 역상전류의 인입등 오조작으로 인한 케이지와 곤도라의 아암이 충돌 파손되는 것을 방지하기 위한 화물용 곤도라의 안전장치에 있어서, 도면 제 3 도 및 4 도에서와 같이 아암(A)의 말단부 양측에 핀 결합되어 하향설치되는 소정길이의 브라켓(1)에 상승제한 및 전원차단용 리미트 스위치(11)를 "ㄷ"형 브라켓(12)으로 부설하고, 상기 양측 브라켓(1)사이의 하부에는, 소정위치 양측에 돌기(21)가 향성되고 중심에 와이어로프(W)가 관통되는 관통홀(22)을 가지는 리미트 스위치 작동용 작동바(2)가 승하강되게 삽입 설치되는 홀더(3)가 고정설치되고, 상기 홀더의 전후방 또는 양극에는 상기 작동바(2)의 돌기(21)가 삽입돌출되어 승하강 안내될 장공(31)을 가지며, 드럼 및 롤러(600)를 걸쳐 상기 작동바(2)에 관통되어 하부로 케이지(C)와 연결된 와이어로프(W)의 작동바 하부소정위치에 역상전원이 걸리거나 오조작시 이 작동바(2)의 저부를 밀어 상승 작동시킬 터치링(4)이 볼트(41)로 체결되어 와이어로프(W)에 고정된 것으로 상기 홀더(3)내부에는 걸림턱부(32)와 돌기(21)사이에 압축스프링체(S)가 탄설된다.In the safety device of the cargo gondola for preventing the collision of the arm of the cage and the gondola due to the misoperation such as the extension of the wire rope and the drawing of the reverse phase current, the arm A as shown in FIGS. 3 and 4 A limiting switch 11 for raising and limiting the power cut-off is attached to the bracket 1 having a predetermined length, which is pin-coupled to both ends of the distal end of the terminal 1, with a "c" type bracket 12, and between the brackets 1 between the two sides. On the lower part, the holder 3 is provided with a limit switch actuating operation bar 2 having a projection hole 21 directed at both sides of a predetermined position and a through hole 22 through which a wire rope W penetrates at the center thereof. ) Is fixedly installed, and the front and rear or the anode of the holder has a long hole 31 to be inserted and projected by the projection 21 of the operation bar (2), the operation bar across the drum and roller 600 (2) penetrated and connected to the cage (C) at the bottom When the reverse phase power is applied to the lower part of the operation bar of the wire rope (W) or when the operation is wrong, the touch ring (4) to push up the bottom of the operation bar (2) is operated with the bolt (41). It is fixed to the inside of the holder 3, the compression spring body (S) is coalesced between the locking jaw portion 32 and the projection (21).
이상과 같이 구성된 본 고안의 작동상태를 살펴보면 제 1 도 및 제 2 도에서와 같이 곤도라의 전원입력에 따라 드럼에 와이어로프(W)가 감기거나 풀리면서 종래의 안전장치가 필요없이 즉 삭제된 상태에서 안내활차(500) 및 아암(A)선단부의 롤러(600)를 걸쳐 늘어뜨려진 와이어로프 단이 케이지(C)에 고정된 상태에서 이 케이지(C) 가 승하강된다.Looking at the operating state of the present invention configured as described above as shown in Figs. 1 and 2, the wire rope (W) is wound or unwound on the drum according to the power input of the gondola, without the need for a conventional safety device, i. This cage (C) is raised and lowered in a state where the wire rope ends draped over the guide pulley 500 and the roller (600) of the arm (A) tip are fixed to the cage (C).
이때 본 고안 장치의 작동바(2)를 관통한 와이어로프는 장애없이 관통홀(22)을 따라 케이지(C)를 승하강시킨다.At this time, the wire rope penetrates the operation bar 2 of the device of the present invention to raise and lower the cage C along the through-hole 22 without obstacle.
그리고 이후 케이지(C)의 상승제한 조작시 오조작이나 역상전류등에 인입된 경우, 케이지(C)의 하강조작이 목적이나 오히려 상승되는데, 이때 도면 제 4a 도의 상태에서와 같이 와이어로프(W)에 볼트(41)로 고정된 터치링(4)이 작동바(2)의 저부에 밀집되어 치게 됨에 따라서, 작동바(2)의 돌기 (21)가 압축스프링체(S)를 압축시키면서 홀더(3)의 장공(31)을 따라 상승되므로서 작동바(2)가 상승되는데 이때 압축스프링체(S)에 의해 충돌력에 대한 완충작용을 함과 동시에 상승되는 작동바(2)의 상부가 리미트 스위치(11)를 작동시키므로써(도면 제 4b 도 참조)곤도라의 구동을 정지시켜 케이지(C)의 과강승을 정지케 하는 것이다.Then, when the cage C is introduced into an incorrect operation or reverse phase current during the operation of limiting the rise of the cage C, the falling operation of the cage C is aimed or rather raised, in which case the wire rope W is connected to the wire rope W as shown in FIG. As the touch ring 4 fixed by the bolt 41 is pressed against the bottom of the operating bar 2, the projection 21 of the operating bar 2 compresses the compression spring body S while the holder 3 is pressed. The operating bar (2) is raised as it rises along the long hole (31) of the upper part. At this time, the upper part of the operating bar (2) which is raised at the same time as the buffering force against the collision force by the compression spring body (S) is the limit switch. By activating (11) (see FIG. 4B), the gondola is stopped to stop the cage C from rising and falling.
그리고, 곤도라의 정상 작동시에는 압축되었던 압축스프링체(S)의 복귀력으로 작동바(2)가 하강되어 도면 제 3 도에서와 같이 돌기(21)가 홀더 (3)의 장공(3)하단부에 위치된다.In addition, during normal operation of the gondola, the operating bar 2 is lowered by the return force of the compressed spring body S that has been compressed so that the projection 21 lowers the long hole 3 of the holder 3 as shown in FIG. Is located in.
이상과 같이 구성되고 작용되는 본 고안은 곤도라 제작시 아암(A)선단 하부에 핀결합시켜 설치하므로써 종래의 안전장치에서와 같은 현장설치시 운전을 하여 위치조정하는 작업이 필요없고 작업자의 부주의로 인한 사고밭생의 원인을 근본적으로 방지함 수 있는 실용적 효과가 있는 것이다.The present invention, which is constructed and operated as described above, is installed by pin-coupling at the lower end of the arm (A) when manufacturing the gondola, so it is not necessary to operate and adjust the position during on-site installation as in the conventional safety device. There is a practical effect that can fundamentally prevent the cause of the accident gardener.
