도1 및 도2에 도시된 바와 같이, 우선 상기 하우징(10)에 대하여 보다 상세하게 설명하면, 상기 하우징(10)은 엘리베이터 카의 일측 또는 양측 또는 도어를 제외한 세 벽면에 모두 구비될 수 있다. 1 and 2, first, the housing 10 will be described in more detail. The housing 10 may be provided on one or both sides of the elevator car or on all three wall surfaces except for the door.
상기 하우징(10)은, 프레임(131)과, 상기 하우징의 중앙부에 형성되어 상기 레일부(GR2)가 수용되는 레일공간(133)과, 상기 레일공간(133)을 중심으로 좌우 대칭되게 배치되어 상기 하우징 프레임(131)에 구비되는 실린더지지부(13)와, 상기 실린더지지부(13)에 의해 지지되는 실린더(20) 및 클램프(30)를 포함하여, 하나의 클램핑유닛(12)을 구성한다. 그리고, 엘리베이터 카의 도어의 열림 및 닫힘 동작에 연동되어 상기 클램핑유닛(12)의 실린더를 구동하는 별도의 구동장치가 구비되는 유압유닛(11)이 상기 클램핑유닛(12)의 상부에 일체로 결합된다.The housing 10 includes a frame 131 , a rail space 133 formed in the central portion of the housing to accommodate the rail portion GR2 , and a left and right symmetrical arrangement around the rail space 133 , One clamping unit 12 is constituted by including a cylinder support part 13 provided in the housing frame 131 , a cylinder 20 supported by the cylinder support part 13 , and a clamp 30 . In addition, the hydraulic unit 11 provided with a separate driving device for driving the cylinder of the clamping unit 12 by interlocking with the opening and closing operations of the door of the elevator car is integrally coupled to the upper portion of the clamping unit 12 . do.
상기 유압유닛(11)에는, 도1 및 도2에 도시된 바와 같이, 상기 실린더(20)에 유체를 공급하는 펌프(P)와 구동모터(M)가 구비되고, 체크밸브(M1), 압력계(M2), ON/OFF 밸브(M3), 압력스위치(M4), 어큐물레이터(Accumulator)(M5), 릴리프밸브(Relief valve)(M6)가 설치되며, 상기 실린더(20)는 유압실린더(20)로 이루어져, 유압력을 클램프(30)로 전달하게 된다.As shown in FIGS. 1 and 2, the hydraulic unit 11 includes a pump P and a driving motor M for supplying fluid to the cylinder 20, a check valve M1, and a pressure gauge.

상기 실린더(20)는 상기 펌프(P)에 의해 공급되는 유압으로 인하여, 상기 플런저(23)가 강한 힘으로 전진하도록 이루어지는 것으로, 상기 케이싱(21)은 상기 실린더지지부(13)에 견고하게 고정된다. 그리고, 상기 하우징(10)의 일측, 즉 하우징(10)을 구성하는 실린더지지부(13)에는 상기 펌프(P)로부터 공급되는 유체를 상기 실린더(20) 내부로 유입시키기 위해 유체 이송로(PR)와 연결되는 연결부(131a)가 형성된다. 그리고, 상기 케이싱(21)에는 상기 연결부(131a)와 연통되며, 유입된 유체를 상기 플런저(23)가 내장되는 동작부(212)로 공급하는 유입공(211)이 형성된다.The cylinder 20 is configured such that the plunger 23 advances with a strong force due to the hydraulic pressure supplied by the pump P, and the casing 21 is firmly fixed to the cylinder support unit 13 . . And, one side of the housing 10, that is, the cylinder support part 13 constituting the housing 10 has a fluid transfer path PR to introduce the fluid supplied from the pump P into the cylinder 20. A connection portion 131a connected to is formed. In addition, an inlet hole 211 communicating with the connection part 131a and supplying the introduced fluid to the operation part 212 in which the plunger 23 is built is formed in the casing 21 .
상기 클램핑유닛(12)에 결합되는 유압유닛(11)에는 상기 연결부(131a)에 대응하는 위치에 대응연결부가 형성된다.In the hydraulic unit 11 coupled to the clamping unit 12, a corresponding connection portion is formed at a position corresponding to the connection portion 131a.
상기 유체가 상기 동작부(212)로 공급되면 동작부(212)에 구비되는 플런저(23)의 후단을 상기 유체가 밀어 플런저(23)가 전진하는데, 이 때 플런저(23)의 후단에는 리세스홈(235)이 형성되어, 플런저(23) 후단에 고른 힘으로 가압력을 전달할 수 있도록 한다.When the fluid is supplied to the operation unit 212, the fluid pushes the rear end of the plunger 23 provided in the operation unit 212, and the plunger 23 advances. At this time, the rear end of the plunger 23 has a recess The groove 235 is formed to transmit the pressing force with an even force to the rear end of the plunger 23 .
또한 상기 플런저(23)의 외면에는 상기 케이싱(21)의 내벽면과의 밀폐력을 높이고 유체가 새어나가는 것을 방지하기 위해, 하나 또는 둘 이상의 패킹부재가 더 구비되는 것이 바람직하다.In addition, it is preferable that one or more packing members are further provided on the outer surface of the plunger 23 in order to increase the sealing force with the inner wall surface of the casing 21 and to prevent the fluid from leaking.
상기 실린더(20)의 플런저(23)는 유체의 공급에 의해 전진하게 되고, 이 전진하는 힘에 의해 상기 클램프(30)를 전진시켜, 상기 클램프(30)의 밀착부가 상기 가이드레일(GR)의 레일부(GR2)를 가압할 수 있도록 한다.The plunger 23 of the cylinder 20 is advanced by the supply of the fluid, and the clamp 30 is advanced by this forward force, so that the contact portion of the clamp 30 is the guide rail GR. The rail part GR2 is pressurized.
상기 클램프(30)는 도면에 나타난 바와 같이, 후단에는 상기 플런저(23)의 선단이 인입되는 내삽공간부(31)가 형성되고, 전단은 상기 가이드레일(GR)의 레일부(GR2)에 밀착되기 위한 평탄형의 밀착부가 형성된다.As shown in the drawing, the clamp 30 has an interpolation space 31 into which the tip of the plunger 23 is inserted at the rear end, and the front end is in close contact with the rail portion GR2 of the guide rail GR. A flat-type contact part is formed for becoming.
또한 앞서 언급한 바와 같이, 상기 하나의 클램프에는 두 개의 실린더(20)가 상하로 가압하도록 이루어지는 바, 상기 클램프 후단에는 두 개의 내삽공간부(31)가 상하로 이격되어 구비된다.In addition, as mentioned above, the one clamp is made to press the two cylinders 20 up and down, and the rear end of the clamp is provided with two interpolation space parts 31 spaced up and down.
다시, 플런저(23)와 내삽공간부(31)의 형상에 대하여 보다 상세하게 설명하면, 상기 플런저(23)의 선단은 원통형이 아니라 선단으로 갈수록 점차 직경이 감소하도록 외면에 라운드부(231)가 형성되고,Again, if the shape of the plunger 23 and the interpolation space part 31 is described in more detail, the tip of the plunger 23 is not cylindrical, but a round part 231 on the outer surface so that the diameter gradually decreases toward the tip. formed,
상기 내삽공간부(31)는 상기 라운드부(231)의 형상에 대응하도록 벽면에 곡선부(33)가 형성된다.The interpolation space portion 31 has a curved portion 33 formed on the wall to correspond to the shape of the round portion 231 .
따라서, 상기 플런저(23)의 라운드부(231) 및 이에 대응하는 상기 클램프(30)의 곡선부(33)의 상호 작용에 의해, 상기 플런저(23)의 가압력이 상기 클램프(30)의 내삽공간부의 중심축선을 따라 정확한 방향으로 전달되며, 더 나아가 보다 안정적으로 가압력이 사방으로 전달되어 힘의 분산이 가능해져, 가이드레일(GR)을 고르게 그리고 견고하고 안전하게 고정할 수 있다.Therefore, by the interaction of the round part 231 of the plunger 23 and the curved part 33 of the clamp 30 corresponding thereto, the pressing force of the plunger 23 is the interpolation space of the clamp 30 . It is transmitted in the correct direction along the central axis of the negative, and furthermore, the pressing force is more stably transmitted in all directions, enabling the distribution of the force, so that the guide rail (GR) can be fixed evenly, firmly and safely.
만약, 상기 클램프의 후단이 평탄하고 상기 플런저(23)의 선단(전방)이 평탄하다면, 플런저(23)가 전진함에 따라 상기 클램프가 점진적으로 천천히 가압되는 것은 본 발명의 라운드부(231)를 구비한 플런저(23) 및 이에 대응하는 곡선부(33)를 구비한 클램프(30)의 동작과 동일하지만, 본 발명과는 다르게 상기 플런저(23)와 밀착되는 부분에만 직선방향으로 가압력이 전달되어 가이드레일(GR)의 면에 고르게 힘이 전달되지 않으며, 플런저(23)가 전진 작동을 할 때에 클램프(30) 또는 플런저(23)의 위치에 약간의 오차가 발생되는 문제도 있다.If the rear end of the clamp is flat and the front end (front) of the plunger 23 is flat, the clamp is gradually and slowly pressed as the plunger 23 advances with the round part 231 of the present invention. It is the same as the operation of the clamp 30 having one plunger 23 and the corresponding curved portion 33, but unlike the present invention, the pressing force is transmitted in a straight direction only to the portion in close contact with the plunger 23 to guide the guide There is also a problem in that the force is not evenly transmitted to the surface of the rail GR, and a slight error occurs in the position of the clamp 30 or the plunger 23 when the plunger 23 moves forward.
또한 상기 플런저(23)가 원통형으로 이루어지고 상기 내삽공간부(31) 또한 이에 대응하여 원통형으로 이루지면, 플런저(23)가 클램프(30) 후단의 정확한 위치를 가압할 수는 있으나, 앞서 언급한 바와 같이 힘이 상기 내삽공간부(31)의 중심축선 을 따라 직선으로만 전달됨에 따라 가압력이 집중되는 한계가 발생한다.In addition, if the plunger 23 is formed in a cylindrical shape and the interpolation space portion 31 is also formed in a cylindrical shape corresponding thereto, the plunger 23 may press the exact position of the rear end of the clamp 30, but the aforementioned As shown, as the force is transmitted only in a straight line along the central axis of the interpolation space 31, a limit in which the pressing force is concentrated occurs.
이와 달리, 본 발명에서 플런저(23)의 선단에 라운드부(231)가 형성되고 상기 내삽공간부(31)에 곡선부(33)가 형성되면, 플런저(23)에서 가해지는 힘은 상기 곡선부(33)를 통해서도 전달됨에 따라 클램프(30)에 고르게 힘이 전달되어 가이드레일(GR)의 일면에 힘이 분산되어 전해짐으로서 가압력이 보다 향상될 수 있다.On the other hand, in the present invention, when the round part 231 is formed at the tip of the plunger 23 and the curved part 33 is formed in the interpolation space part 31, the force applied by the plunger 23 is the curved part. As it is also transmitted through (33), the force is evenly transmitted to the clamp 30, so that the force is distributed and transmitted to one surface of the guide rail (GR), so that the pressing force can be further improved.
아울러, 상기 플런저(23)에는 탄성체내장부(232)가 더 구비되고, 이 탄성체내장부(232)에 탄성부재(37)가 더 구비되어, 상기 플런저(23)와 상기 클램프 사이에 탄성력을 더 부여할 수 있도록 이루어지며, 이 때 이 탄성부재(37)가 지지력을 받을 수 있도록 상기 내삽공간부(31)에서 상기 곡선부(33) 전방에는 평탄형의 평탄지지부(35)가 형성되고, 상기 탄성체내장부(232)에는 후단지지부(234)가 형성되어, 상기 탄성부재(37)의 양단이 평탄지지부(35) 및 후단지지부(234)에 밀착되어 지지력을 받을 수 있도록 한다.In addition, the plunger 23 is further provided with an elastic internal part 232, and an elastic member 37 is further provided on the elastic internal part 232, so that an elastic force is further provided between the plunger 23 and the clamp. In this case, a flat support part 35 of a flat type is formed in front of the curved part 33 in the interpolation space part 31 so that the elastic member 37 can receive a supporting force, and the A rear end support portion 234 is formed in the elastic body embedded portion 232 so that both ends of the elastic member 37 are in close contact with the flat support portion 35 and the rear end support portion 234 to receive support.
따라서 상기 탄성부재(37)의 탄성력에 의해 가이드레일(GR) 양측에 구비되는 총 4개의 실린더가 동시에 가압력을 전달받아 클램프(30)가 동시에 가이드레일(GR)의 양측을 가압하여 고정할 수 있도록 이루어진다.Therefore, a total of four cylinders provided on both sides of the guide rail GR by the elastic force of the elastic member 37 receive pressing force at the same time so that the clamp 30 simultaneously presses both sides of the guide rail GR to fix it. is done
구체적으로는 클램프(30) 중 어느 한 쪽이 가이드레일(GR)에 선 접촉 되더라도, 탄성부재의 탄성력에 의해 가압력은 전달되지 않으며, 실린더(20)에 유체가 공급되어 전진하게 되면 이 탄성부재(37)가 완전히 압축된 이후에 가압력이 전달되도록 이루어짐에 따라 클램프(30)가 가이드레일(GR)의 양측을 동시에 가압할 수 있게 된다.Specifically, even if one of the clamps 30 is in line contact with the guide rail GR, the pressing force is not transmitted by the elastic force of the elastic member, and when the fluid is supplied to the cylinder 20 and moves forward, the elastic member ( As the pressing force is transmitted after the 37) is completely compressed, the clamp 30 can simultaneously press both sides of the guide rail GR.
더 나아가 후술하는 복귀스프링에 의하여 2중으로 탄성력이 부여됨에 따라 실린더(20)의 힘이 완벽하게 동시에 전달되는 효과가 있다.Furthermore, there is an effect that the force of the cylinder 20 is perfectly and simultaneously transmitted as the elastic force is given double by the return spring to be described later.
나아가 본 발명은 상기 실린더(20)에 공급되는 유압이 해제되는 경우, 상기 실린더(20)의 플런저(23)를 원위치 시킬 필요가 있으며, 이를 위하여 복귀유닛(40)을 더 구비하고 있다.Furthermore, in the present invention, when the hydraulic pressure supplied to the cylinder 20 is released, it is necessary to return the plunger 23 of the cylinder 20 to its original position, and for this purpose, a return unit 40 is further provided.
상기 복귀유닛(40)은 상기 하우징(10) 일측에 돌출되도록 구비되되 상기 하우징(10)를 관통하여 상기 클램프와 고정되는 복귀부재(43)와, 상기 하우징(10) 일측에 복귀부재(43)의 일부에 외삽되어 상기 하우징(10)의 외면과 복귀부재(43)의 단부 사이를 지지하는 복귀유도스프링(41)을 포함하여 이루어진다.The return unit 40 is provided to protrude from one side of the housing 10 , a return member 43 penetrating through the housing 10 and fixed to the clamp, and a return member 43 on one side of the housing 10 . A return induction spring 41 is extrapolated to a portion of the housing 10 to support between the outer surface of the housing 10 and the end of the return member 43 .
즉, 유압회로 내에 압축되어 있던 작동유가 방출되면, 상기 압축된 복귀유도스프링(41)의 복원력에 의해 클램프가 복귀부재(43) 및 이에 연결되는 클램프가 후퇴하게 되며, 상기 클램프가 후퇴함으로서 상기 실린더(20)의 플런저(23) 또한 원위치되게 된다.That is, when the hydraulic oil compressed in the hydraulic circuit is released, the clamp return member 43 and the clamp connected thereto are retracted by the restoring force of the compressed return induction spring 41, and as the clamp retracts, the cylinder The plunger 23 of (20) is also brought to the original position.
이 때 상기 탄성부재(37)가 또 다른 역할을 하게 되는데, 보다 상세하게는 상기 플런저(23)가 후퇴하기 위해서는 상기 케이싱(21) 내부에 인입된 유체가 배출되어야 하며, 복귀유도스프링(41)의 복원속도와 유체의 배출 속도는 차이가 날 수 밖에 없기 때문에 상기 탄성부재(37)가 압축되면서 이 속도를 맞추어 안정적으로 복원될 수 있게 된다.At this time, the elastic member 37 plays another role, and more specifically, in order for the plunger 23 to retreat, the fluid introduced into the casing 21 must be discharged, and the return induction spring 41 . Since there is inevitably a difference between the recovery speed and the discharge speed of the fluid, the elastic member 37 is compressed and can be stably restored by matching this speed.
