본 고안은 유압승강기의 로프설치구조에 관한 것으로, 특히 협소한 승가로에서 발생하는 케이지 하부 구성기구들간의 간섭과 케이지의 편하중을 방지할 수 있도록 한 것이다.The present invention relates to a rope installation structure of the hydraulic elevator, in particular to prevent interference between the cage lower components occurring in the narrow roadway and the load of the cage.

일반적으로 유압승강기를 배치함에 있어서는 포크식(fork type)과 언더 슬링식(unddr sling type)이 있는데 전자는 케이지의 상측에서 실린더에 의해 케이지를 승강시키는 방식으로 1000㎏이하의 경하중에 이용되는 배치방식이고, 후자는 케이지를 옆에서 승강시키는 것으로 1000㎏이상의 중하중용의 승강기에 이용되는 배치방식으로 구분된다.In general, there are fork type and under sling type in arranging hydraulic elevators. The former is used for light load of less than 1000kg by lifting the cage by cylinder from the upper side of the cage. The latter is classified into a batch system used for lifting a heavy load of 1000 kg or more by raising and lowering the cage by the side.

본 고안은 언더 슬링식의 배치구종에 대한 것으로 우선 종래 승강기의 언더 슬링식 배치구조를 보면 제1도 내지 제3도에 도시된 바와같이 케이지(1)가 가이드 레일(2)과 레일 브라켓(3)에 고정되어 있고 케이지(1) 하방의 피트상에는 버퍼와 함께 버퍼스프링(4)이 장착되어 있으며 케이지(1) 일측의 피트상에는 잭 다이(5)가 고정설치되어 있다.The present invention relates to an undersling type arrangement. First, the undersling type arrangement structure of a conventional elevator as shown in Figures 1 to 3, the cage 1 is a guide rail (2) and the rail bracket (3) ) And a buffer spring 4 is mounted on the pit below the cage 1 together with a buffer, and a jack die 5 is fixed on the pit on one side of the cage 1.

또 잭 다이(5)상에 유압실린더(6)가 고정되며 유압실린더(6)의 피스톤 상단에 복수개의 풀리(7)(7a)가 고정되면서 가이드 레일(2)과 레일 브라켓(3)에 고정되어 있고 케이지(1) 하부에는 프레임(9)(10)이 설치 고정되면서 잭 다이(5)의 하부공간과 프레임(10)에 풀리(7b)(7c)(7d)가 연결되어 있으며 로프(11)의 일단이 잭 다이(5)에 고정되고 타단은 풀리(7)(7a)(7b)(7c)(7d)를 거쳐 상방의 빔(12)에 고정되어 있는 것이다.In addition, the hydraulic cylinder 6 is fixed on the jack die 5 and the plurality of pulleys 7 and 7a are fixed to the upper end of the piston of the hydraulic cylinder 6 while being fixed to the guide rail 2 and the rail bracket 3. The frame 9, 10 is fixed to the lower part of the cage (1), and the pulleys 7b, 7c, 7d are connected to the lower space of the jack die 5 and the frame 10, and the rope 11 Is fixed to the jack die 5, and the other end is fixed to the upper beam 12 via pulleys 7, 7a, 7b, 7c, and 7d.

이와같은 종래의 유압승강기의 배치구조는 실린더(6)가 작동하여 그 피스톤에 의해 풀리(7)(7a)가 상승하면 로프(11) 전체가 긴장되면서 풀리(7)(7a)를 통해 피스턴의 상승에 비례한 양만큼의 로프(11)가 풀리(7b)(7c)(7d)를 당겨서 들어오게 되므로써 케이지(1)가 상승하는 것이다.The arrangement of the conventional hydraulic elevator is such that when the cylinder 6 is operated and the pulleys 7 and 7a are raised by the pistons, the entire rope 11 is tensioned and the pistons are pulled through the pulleys 7 and 7a. As the rope 11 is pulled in by pulling the pulleys 7b, 7c and 7d in an amount proportional to the rise, the cage 1 is raised.

여기서 로프(11)는 실린더측에서 4번 감기고 케이측에서 2번 감긴 것으로 실린더(6)의 피스톤에 10㎜상승하면 케이지(1)는 20㎜상승하는데 이를 2 : 4로핑이라 한다.Here, the rope 11 is wound four times on the cylinder side and wound twice on the cable side. When the cage 1 rises 10 mm on the piston of the cylinder 6, the cage 1 rises 20 mm, which is called 2: 4 rope.

그러나 종래의 승강기 배치구조는,However, the conventional elevator arrangement structure,

1. 실린더측의 승강로가 협소한 경우 실린더측의 레일을 세우기 위하여 실린더를 전방측으로 당겨 설치해야 하므로 편하중이 발생하는 상태를 설치될 수 밖에 없다.1. In the case where the lift path on the cylinder side is narrow, the cylinder must be installed to the front side to raise the rail on the cylinder side.

2. 승강로가 협소하지 않은 경우라도 프레임(10)이 경사설치되므로 케이지(1)의 하부 프레임(10)과 간섭이 발생되고 또한 케이지(1)의 타부 프레임(10)에 설치되는 슬링 웨지(sling wedge), 가이드 슈우(guide shoe)등과도 간섭이 일어나 이 간섭부위를 절단해냄에 따라 장치의 강도가 취약하게 된다.2. Even when the hoistway is not narrow, the frame 10 is inclined so that the interference with the lower frame 10 of the cage 1 is generated and the sling wedge is installed on the other frame 10 of the cage 1. Interference also occurs with wedges, guide shoes, and the like, resulting in weakening the strength of the device as it cuts off these interferences.

3. 케이지 폭이 작은 경우에는 버퍼 스프링(4)이 로프(11) 사이에 들어가게 되므로 버퍼 스프링을 상, 하로 이동하여 설치해야 하나 프레임(10)이 경사설치되어 잇어 설치장소가 마땅하지 않다.3. If the cage width is small, the buffer spring (4) is to enter between the rope 11, so the buffer spring should be moved up and down, but the frame 10 is inclined installation place is not appropriate.

본 고안은 승강로가 협소하더라도 편하중없이 승강기의 배치를 실현하고 아울러 케이지 하부기구들간의 간섭을 방지할 수 있는 유압승강기 배치구조를 제공하려는 것으로 로프 끝단의 고정위치를 변경하고 프레임을 복수개소에 설치하여 프레임간의 거리를 조정할 수 있게 한 것이다.The present invention aims to provide a hydraulic elevator arrangement structure that realizes the arrangement of the elevator without any load even when the elevator track is narrow and prevents the interference between the lower mechanisms of the cage, and changes the fixed position of the rope end and installs the frame in multiple places. The distance between the frames can be adjusted.

이를 첨부도면에 의해 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

케이지(1)를 양측의 가이드 레일(2)과 레일 브라켓(3)에 고정하고 피트의 일측상에 설치한 잭 다이(5)에 실린더(6)를 설치하여 가이드 레일(8)과 레일 브라켓(3)에 고정하며 실린더(6)를 설치하여 가이드 레일(8)과 레일 브라켓(3)에 고정하며 실린더(6)의 피스톤 상단에 풀리(7)(7a)를 고정하면서 잭 다이(5)에는 풀리(7b)를 설치 고정하였다.The cage (1) is fixed to the guide rails (2) and the rail bracket (3) on both sides, and the cylinder (6) is installed on the jack die (5) installed on one side of the pit, so that the guide rail (8) and the rail bracket ( 3) to the guide rail (8) and the rail bracket (3) by installing the cylinder (6) and to the jack die (5) while fixing the pulleys (7) (7a) on the top of the piston of the cylinder (6). The pulley 7b was installed and fixed.

또 케이지(1) 하부에 프레임(9a)(9b)(10)을 설치하고 프레임(9a)(9b)에 풀리(7'c)(7'd)(7''c)(7''d)를 수직으로 설치하며 그 하방의 피트상에는 버퍼 스프링(4)을 고정한다.In addition, the frame 9a, 9b, 10 is installed in the lower part of the cage 1, and the pulleys 7'c, 7'd, 7''c, 7''d are mounted on the frames 9a, 9b. ) Is installed vertically and the buffer spring 4 is fixed on the lower pit.

실린더(6)의 풀리(7)(7a) 상방으로는 빔(20)이 설치되어 풀리(21)(21a)를 고정한 것이다.The beam 20 is provided above the pulleys 7 and 7a of the cylinder 6 to fix the pulleys 21 and 21a.

또한 로프(11)은 잭 다이(5)에 일단이 고정되고 타단은 풀리(7)(7b)(7a)(7''d)(7''c)(21a)(21)(7'c)(7'd)를 거쳐 상방의 빔(12)에 고정한 것이다.In addition, one end of the rope 11 is fixed to the jack die 5, and the other end is pulley (7) (7b) (7a) (7''d) (7''c) (21a) (21) (7'c). It is fixed to the beam 12 above via (7'd).

따라서 본 고안은 실린더(6)가 작동하여 피스톤과 함께 풀리(7)(7a)가 상승하면 풀리(7b)(7''d),(7''c)(21a)(21)(7'c)(7'd)로 부터의 로프(11)가 실린더측으로 당겨지므로 케이지(1)가 상승하게 되는 것이며, 이때 로프(11)에 의한 풀리들의 동력전달순서는 풀리(7)(7b)(7a)(7"d)(7''c)(21a)(21)(7'c)(7'd)의 순으로 이루어 진다.Thus, the present invention provides that the pulleys (7) (7''d), (7''c) (21a) (21) (7 ') when the cylinder (6) is operated to raise the pulleys (7) (7a) together with the pistons. c) As the rope 11 from 7'd is pulled to the cylinder side, the cage 1 is raised, and the power transmission sequence of the pulleys by the rope 11 is pulley 7, 7b ( 7a) (7 "d) (7''c) (21a) (21) (7'c) (7'd).

여기서 실린더측과 케이측의 로프가 각각 4번씩 감겨져 있으므로 실린더(6)가 10㎜상승하면 케이지(1)도 10㎜의 높이로 상승하게 되는데 이는 4 : 4로핑이므로 종래의 2 : 4로핑과 같은 속도비율을 얻으려면 4 : 8로핑이 되도록 해야한다.Since the ropes of the cylinder side and the cable side are wound four times, respectively, when the cylinder 6 rises 10 mm, the cage 1 also rises to a height of 10 mm, which is the same as the conventional 2: 4 rope because of the 4: 4 rope. To get the speed ratio, you need to have 4: 8 roping.

제7도 및 제8도는 이러한 4 : 8로핑을 위한 다른 실시예를 나타낸 것이다.7 and 8 show another embodiment for such 4: 8 roping.

이는 실린더(6) 상부에 설치되는 풀리를 4개의 풀리(7)(7a)(7')(7'a)로 하고 잭 다이(5)에 설치되는 풀리는 3개의 풀리(7d)(7'd)(7''d)를 형성하여 로프(11)에 의한 풀리의 동력전달순서가 풀리(7)(7b)(7a)(7'd)(7')(7''b)(7'a)(7''d)(7''c)(21a)(21)(7'c)(7'd)의 순으로 이루어진도록 한다.This is made of four pulleys (7) (7a) (7 ') (7'a), which are installed on the cylinder (6), and three pulleys (7d) (7'd). (7''d) so that the power transmission sequence of the pulley by the rope 11 is the pulley (7) (7b) (7a) (7'd) (7 ') (7''b) (7' a) (7''d) (7''c) (21a) (21) (7'c) (7'd).

이상에서와 같이 본 고안은 프레임이 경사설치되는 일이 없으므로 케이지 하부 구성부품들의 간섭을 방지할 수 있게 되었고 승강로가 협소한 경우에도 로프 끝단의 연결위치를 변경 적용할 수 있으며 케이지 하부에 프레임이 양측으로 설치되므로 편하중이 방지된다.As described above, the present invention can prevent interference of lower components of the cage because the frame is not inclined and can be applied by changing the connection position of the end of the rope even when the hoistway is narrow. Since it is installed as, the load is prevented.

또한 케이지 폭이 적어도 케이지 하부 양측 프레임간의 거리를 조정할 수 있어 버퍼 스프링과 로프간의 간섭을 방지할 수 이게 된 산업상 유용한 고안인 것이다.In addition, the cage width can be adjusted at least the distance between the frame of the lower side of the cage is an industrially useful design that can prevent the interference between the buffer spring and the rope.
