일반적으로, 점프 엘리베이터란 대형 건설 현장에서 요구가 늘어가고 있는 신 공법으로서, 해당 건축물의 공정 진행에 따라 골조가 완료된 구간에 엘리베이터를 순차적으로 시공하여 수직 교통 수단으로 제공하는 새로운 설치 공법을 일컫는다.In general, a jump elevator is a new construction method that is increasing in demand at large construction sites, and refers to a new installation method that sequentially constructs an elevator in a section where a frame is completed according to the process progress of the corresponding building and provides it as a vertical transportation method.
이는 일반 호이스트와 대비하여 운송효율이 우수한 엘리베이터를 골조 완료전, 공사용으로 사용하고자 하는 고객들의 요구가 늘어가고 있는 시점에서, 이러한 신 공법은 엘리베이터에 의한 건축 시장 변화를 주도할 것으로 전망되고 있다.This new construction method is expected to lead to a change in the construction market by elevators, as the demand for customers who want to use elevators with high transportation efficiency compared to general hoists for framing construction is increasing.
이러한 점프 엘리베이터 설치 공법은 건물의 골조 완성 후 설치를 시작하는 기존 방식과 달리 공사 초기에 설치해 골조가 상승함에 따라 기계실도 상부로 이동시켜 가는 방식으로, 골조 공정 중에도 엘리베이터를 인력 및 자재 운송용으로 사용할 수 있을 뿐만 아니라 건물 외부에 설치하는 호이스트와 달리 건물 내부에 설치되기 때문에 비, 바람과 같은 외부 환경 영향을 받지 않고 사용할 수 있으며, 건설 공기를 단축할 수 있는 등의 장점이 있다.Unlike the conventional method of starting the installation after the completion of the frame of the building, this jump elevator installation method moves the machine room to the upper part as the frame rises by installing at the beginning of the construction, and the elevator can be used for transportation of personnel and materials even during the framing process. In addition to the hoist installed outside the building, it is installed inside the building and can be used without being affected by external environments such as rain and wind, and has the advantage of shortening construction air.
도 1은 일반적인 점프 엘리베이터 설치 공법을 설명하기 위한 도면이다.1 is a view for explaining a general jump elevator installation method.
도 1에 도시된 바와 같이 건물의 건설 진행 과정에서 건물 내부에 승강로(10)를 설치하게 되는데, 건물의 건설 과정이 완료되기 이전의 승강로 상에 엘리베이터를 설치한다. 먼저, 승강로(10) 내부에 가이드 레일(20)을 수직 방향으로 설치하고, 이동 기계실(50) 및 엘리베이터 카(60)를 설치한다. 가이드 레일(20)은 일반 엘리베이터 설치 방식과 마찬가지로 레일 브래킷(21)을 통해 수직 방향으로 고정 지지된다. 이동 기계실(50)에는 권상기(51)가 구비되며, 엘리베이터 카(60)는 와이어 로프를 통해 권상기(510)에 연결되어 승강 구동된다. 이동 기계실(50)의 상부에는 가이드 레일(20) 등의 설치 작업을 위한 별도의 임시 작업카(30)가 설치된다. As shown in FIG. 1, during the construction process of the building, the hoistway 10 is installed inside the building, and an elevator is installed on the hoistway before the building construction process is completed. First, the guide rail 20 is installed in the hoistway 10 in the vertical direction, and the moving machine room 50 and the elevator car 60 are installed. The guide rail 20 is fixedly supported in the vertical direction through the rail bracket 21 as in the general elevator installation method. The moving machine room 50 is provided with a hoisting machine 51, and the elevator car 60 is connected to the hoisting machine 510 through a wire rope and is driven up and down. A separate temporary work car 30 for installation work such as a guide rail 20 is installed on the upper part of the moving machine room 50.
건물 건설 과정이 진행됨에 따라 승강로(10) 및 가이드 레일(20)이 상측으로 연장 형성되며, 이동 기계실(50)이 상측으로 이동하고, 임시 작업카(30) 또한 상측으로 이동한다. 엘리베이터 카(60), 이동 기계실(50) 및 임시 작업카(30)가 가이드 레일(20)을 따라 이동하게 되므로, 엘리베이터 카(60), 이동 기계실(50) 및 임시 작업카(30)의 외측단부에는 가이드 레일(20)과 접촉하는 가이드 슈(40)가 결합되어 이동 경로가 가이드된다.As the building construction process progresses, the hoistway 10 and the guide rail 20 are formed to extend upward, the moving machine room 50 moves upward, and the temporary work car 30 also moves upward. Since the elevator car 60, the moving machine room 50, and the temporary work car 30 move along the guide rail 20, the elevator car 60, the moving machine room 50, and the outside of the temporary work car 30 At the end, a guide shoe 40 in contact with the guide rail 20 is coupled to guide the movement path.
엘리베이터 카(60)에는 일반적인 방식의 엘리베이터 카(60)와 마찬가지로 엘리베이터 카(60)의 추락을 방지하는 안전 장치들이 다양하게 마련되는데, 기계적인 안전 장치로서 비상 제동 장치 등이 설치된다. 이동 기계실(50) 또한 안정적으로 고정되어야 하므로, 추락 및 하향 이동을 방지하기 위한 별도의 안전 장치가 설치되어 있다.The elevator car 60 is provided with a variety of safety devices to prevent the fall of the elevator car 60, like the general type of elevator car 60, an emergency braking device or the like is installed as a mechanical safety device. Since the moving machine room 50 must also be stably fixed, a separate safety device is installed to prevent the fall and the downward movement.
그러나, 임시 작업카(30)는 단순히 건설 현장의 크레인을 통해 지지되어 있을 뿐 추락 등을 방지할 수 있는 별도의 안전 장치가 설치되어 있지 않다. 임시 작업카(30)가 추락하게 되면, 이동 기계실(50)과 충돌하게 되어 중대한 안전 사고로 이어질 수 있어 임시 작업카(30)에 대한 안전 장치로서 추락 방지 장치에 대한 개발이 시급한 실정이다.However, the temporary work car 30 is simply supported by a crane at the construction site, and there is no separate safety device that can prevent a fall. When the temporary work car 30 falls, it may collide with the mobile machine room 50 and lead to a serious safety accident, so it is urgent to develop a fall prevention device as a safety device for the temporary work car 30.

본 발명의 일 실시예에 따른 임시 작업카 추락 방지 장치는, 건물의 건설 진행 공정에 따라 엘리베이터 설치 과정을 순차적으로 수행하는 점프 엘리베이터 설치 공법에서, 엘리베이터 카를 승강 구동하는 이동 기계실의 상부에 설치되는 임시 작업카(30)가 추락하는 것을 기계적인 구성을 통해 방지하기 위한 장치로서, 중간 부위가 임시 작업카(30)의 일측에 회동 가능하게 결합되며 기준 위치 상태에서 일단부가 임시 작업카(30)의 외측 방향으로 돌출되게 형성되는 걸림 레버(100)와, 걸림 레버(100)가 기준 위치 상태로 유지되도록 걸림 레버(100)를 탄성 지지하는 탄성 스프링(200)을 포함하여 구성된다.Temporary work car fall prevention device according to an embodiment of the present invention, in a jump elevator installation method that sequentially performs the elevator installation process according to the construction process of the building, the temporary installed on the upper portion of the mobile machine room to drive the elevator car up and down As a device for preventing the work car 30 from falling through a mechanical configuration, the intermediate part is rotatably coupled to one side of the temporary work car 30 and one end of the temporary work car 30 in the reference position state It is configured to include an elastic spring 200 elastically supporting the locking lever 100 so that the locking lever 100 is formed to protrude outwardly and the locking lever 100 is maintained in a reference position.
이때, 걸림 레버(100)는 기준 위치 상태에서 임시 작업카(30)가 하강 이동함에 따라 일단부가 승강로의 가이드 레일을 지지하는 레일 브래킷(21)에 맞물림 지지되도록 형성된다.At this time, the locking lever 100 is formed so that one end is engaged with the rail bracket 21 supporting the guide rail of the hoistway as the temporary work car 30 moves downward in the reference position state.
걸림 레버(100)의 구성을 좀더 구체적으로 살펴보면, 걸림 레버(100)는, 중간 부위에 형성되어 임시 작업카(30)에 결합되는 회전축(110)과, 기준 위치 상태에서 회전축(110) 영역으로부터 임시 작업카(30)의 외측 방향으로 돌출되게 연장되는 걸림 바디부(120)와, 회전축(110) 영역으로부터 걸림 바디부(120)와 교차하는 방향으로 연장되는 회동 바디부(130)를 포함하고, 걸림 바디부(120)가 기준 위치 상태에서 레일 브래킷(21)에 맞물림 지지될 수 있도록 형성된다.Looking at the configuration of the engaging lever 100 in more detail, the engaging lever 100 is formed in an intermediate portion, the rotating shaft 110 coupled to the temporary work car 30 and the rotating shaft 110 from the reference position state It includes a locking body portion 130 extending protruding in the outer direction of the temporary work car 30, and a rotating body portion 130 extending in a direction crossing the locking body portion 120 from the rotation shaft 110 region , The engaging body portion 120 is formed to be engaged with the rail bracket 21 in a reference position state.
이때, 탄성 스프링(200)은 일단이 걸림 레버(100)의 회동 바디부(130)에 결합되고 타단이 임시 작업카(30)의 일측에 결합되며, 탄성 스프링(200)의 탄성 복원력에 의해 걸림 레버(100)를 기준 위치 상태로 회동 복원시키도록 구성된다.At this time, the elastic spring 200 is one end is coupled to the pivoting body portion 130 of the locking lever 100, the other end is coupled to one side of the temporary work car 30, and is caught by the elastic restoring force of the elastic spring 200 It is configured to restore the lever 100 to the reference position state.
즉, 걸림 레버(100)는 중간 부위의 회전축(110)을 중심으로 회동 가능하게 결합되는데, 도 3에 도시된 바와 같이 걸림 바디부(120)가 임시 작업카(30)의 외측 방향으로 돌출된 상태인 기준 위치 상태로 유지되도록 탄성 스프링(200)의 탄성력에 의해 탄성 회전 지지된다.That is, the engaging lever 100 is rotatably coupled around the rotation shaft 110 of the middle portion, as shown in Figure 3, the engaging body portion 120 protrudes in the outward direction of the temporary work car 30 It is elastically supported by the elastic force of the elastic spring 200 so as to be maintained in the state of the reference position.
이때, 걸림 레버(100)의 회동 바디부(130)의 끝단에는 탄성 스프링(200)에 의한 걸림 레버(100)의 일방향 탄성 회동을 기준 위치 상태로 제한할 수 있도록 스토퍼 로드(140)가 결합될 수 있다. 따라서, 걸림 레버(100)는 탄성 스프링(200)의 탄성력에 의해 도 3에 도시된 방향을 기준으로 반시계 방향으로 탄성 회전하게 되는데, 이 과정에서 스토퍼 로드(140)가 임시 작업카(30)에 맞물림되어 탄성 회전을 구속하게 되므로, 이러한 일방향 회전 구속 상태가 기준 위치 상태가 된다.At this time, the stopper rod 140 is coupled to the end of the rotating body portion 130 of the locking lever 100 to limit the one-way elastic rotation of the locking lever 100 by the elastic spring 200 to a reference position state. Can. Therefore, the engaging lever 100 is elastically rotated in the counterclockwise direction based on the direction shown in FIG. 3 by the elastic force of the elastic spring 200. In this process, the stopper rod 140 temporarily moves the car 30. Since the elastic rotation is constrained by being engaged with, the one-way rotation restraint state becomes a reference position state.
이러한 기준 위치 상태에서 걸림 레버(100)는 걸림 바디부(120)가 임시 작업카(30)의 외측 방향으로 돌출되므로, 임시 작업카(30)가 하향 이동하게 되면, 걸림 바디부(120)가 레일 브래킷(21)에 맞물림 지지되므로, 더이상의 하향 이동이 방지된다. 즉, 추락이 방지된다.In this reference position state, the locking lever 100 has the locking body portion 120 protruding outward from the temporary working car 30, and thus, when the temporary working car 30 moves downward, the locking body 120 Since it is engaged with the rail bracket 21, further downward movement is prevented. That is, fall is prevented.
임시 작업카(30)는 도 2에 도시된 바와 같이 복수개의 프레임들로 이루어지는데, 기둥 역할을 하는 포스트 빔(31)이 양측면에 설치되고, 이러한 포스트 빔(31)을 연결하는 가로 빔(32)들을 통해 직육면체 형태로 이루어질 수 있다.The temporary work car 30 is made of a plurality of frames, as shown in FIG. 2, a post beam 31 serving as a pillar is installed on both sides, and a horizontal beam 32 connecting these post beams 31 ) Can be made in the form of a cuboid.
걸림 레버(100)는 임시 작업카(30)의 기둥 역할을 하는 포스트 빔(31)에 설치되는 것이 바람직한데, 이때, 도 4에 도시된 바와 같이 걸림 레버(100)가 2개 구비되어 포스트 빔(31) 양측면에 각각 서로 대응되게 결합되며, 스토퍼 로드(140)가 2개의 걸림 레버(100)에 동시에 관통 결합되어 2개의 걸림 레버(100)가 동시에 일체로 회동하도록 구성될 수 있다.The locking lever 100 is preferably installed on the post beam 31 serving as a pillar of the temporary work car 30. At this time, as shown in FIG. 4, two locking levers 100 are provided to post the beam. (31) Each of the two sides is coupled to correspond to each other, the stopper rod 140 is coupled to the two engaging levers 100 at the same time can be configured to rotate the two engaging levers 100 at the same time integrally.
이때, 스토퍼 로드(140)는 임시 작업카(30)의 포스트 빔(31)에 맞물림되어 걸림 레버(100)의 일방향 회동을 구속하게 된다.At this time, the stopper rod 140 is engaged with the post beam 31 of the temporary work car 30 to restrain one-way rotation of the locking lever 100.
한편, 걸림 레버(100)의 걸림 바디부(120) 끝단에는 걸림 레버(100)가 레일 브래킷(21)에 맞물림 지지된 상태에서 레일 브래킷(21)의 끝단을 감싸며 맞물림될 수 있도록 별도의 후크 돌기(121)가 하향 돌출 형성될 수 있으며, 이를 통해 걸림 레버(100)의 레일 브래킷(21)에 대한 맞물림 상태가 더욱 안정적으로 유지될 수 있다.On the other hand, at the end of the locking body portion 120 of the locking lever 100, a separate hook projection is provided so that the locking lever 100 is wrapped around the end of the rail bracket 21 in a state where the locking lever 100 is engaged with the rail bracket 21. 121 may be formed to protrude downward, through which the engagement state of the engaging lever 100 with respect to the rail bracket 21 can be more stably maintained.
이와 같이 구성된 임시 작업카 추락 방지 장치의 작동 상태를 살펴보면, 도 5의 (a) 및 (b)에 도시된 바와 같이 걸림 레버(100)는 탄성 스프링(200)의 탄성력에 의해 기준 위치 상태로 유지되고, 이 상태에서 임시 작업카가 하향 이동하는 경우, 걸림 레버(100)가 레일 브래킷(21)에 맞물림 지지되므로, 임시 작업카의 추락을 방지할 수 있다. 특히, 임시 작업카(30)가 특정 위치에 고정 설치된 상태에서 걸림 레버(100)가 레일 브래킷(21)에 맞물림되지 않고 이격된 상태에 있을 수 있는데, 레일 브래킷(21)은 가이드 레일을 지지하기 위해 일정 간격마다 설치되므로, 임시 작업카(30)가 추락하는 경우, 추락 과정에서 걸림 레버(100)가 하부에 가장 근접한 레일 브래킷(21)에 맞물림 지지되므로, 그 이상 추락하는 것을 방지한다.Looking at the operating state of the temporary work car fall prevention device configured as described above, as shown in (a) and (b) of Figure 5, the locking lever 100 is maintained in the reference position state by the elastic force of the elastic spring 200 When the temporary work car moves downward in this state, since the engaging lever 100 is engaged with the rail bracket 21, the fall of the temporary work car can be prevented. In particular, while the temporary work car 30 is fixedly installed in a specific position, the locking lever 100 may be in a spaced state without being engaged with the rail bracket 21, and the rail bracket 21 supports the guide rail Since it is installed at regular intervals, if the temporary work car 30 falls, the locking lever 100 is engaged with the rail bracket 21 closest to the lower part in the fall process, thereby preventing further fall.
한편, 임시 작업카(30)는 전술한 바와 같이 이동 기계실과 함께 건물의 진행 공정에 따라 상승 이동하게 되는데, 이러한 상승 이동 과정에서는 도 5의 (b),(c),(d)에 도시된 바와 같이 걸림 레버(100)가 레일 브래킷(21)에 가압 접촉됨에 따라 회전축(110)을 중심으로 시계 방향으로 회전하며 레일 브래킷(21)과의 간섭을 회피하게 된다. 이때, 탄성 스프링(200)의 탄성력이 계속 작용하게 되므로, 임시 작업카(30)의 상승 이동 과정에서 걸림 레버(100)가 레일 브래킷(21)에 의한 가압 접촉 상태가 해제되면, 도 5의 (e)에 도시된 바와 같이 탄성 스프링(200)의 탄성력에 의해 다시 기준 위치 상태로 회동 복원된다.On the other hand, the temporary work car 30 is moved upwards according to the progress of the building together with the moving machine room as described above, in this upward movement process shown in (b), (c), (d) of Figure 5 As the locking lever 100 is pressed into contact with the rail bracket 21, it rotates clockwise around the rotation shaft 110 and avoids interference with the rail bracket 21. At this time, since the elastic force of the elastic spring 200 continues to act, when the engaging lever 100 is released from the pressure contact state by the rail bracket 21 in the process of moving the temporary work car 30, the ( As shown in e), the rotation is restored to the reference position state again by the elastic force of the elastic spring 200.
즉, 걸림 레버(100)는 임시 작업카(30)의 하향 이동시에는 레일 브래킷(21)에 맞물림 지지되어 임시 작업카(30)의 추락을 방지하지만, 임시 작업카(30)의 상향 이동시에는 회전축(110)을 중심으로 회동하여 레일 브래킷(21)과의 간섭을 회피하게 되며, 탄성 스프링(200)의 탄성력에 의해 다시 기준 위치 상태로 회동 복원된다.That is, the locking lever 100 is engaged with the rail bracket 21 when the temporary work car 30 moves downward, thereby preventing the temporary work car 30 from falling, but the rotating shaft when the temporary work car 30 moves upward By rotating around (110) to avoid interference with the rail bracket (21), it is rotated back to the reference position by the elastic force of the elastic spring (200).
