Description

승강기 견인력 측정장치Elevator Traction Measurement Device
본 발명은 승강기의 견인력 측정장치에 관한 것으로, 더 상세하게는 승강카의 승하강을 견인하는 권상로프의 견인력을 측정하기 위해 권상로프에 직접 부착하여 견인력을 측정하는 장치에 대한 것이다.The present invention relates to an apparatus for measuring a traction force of an elevator, and more particularly, to an apparatus for directly measuring a traction force by measuring a traction force of a hoisting rope that pulls up and down an elevator car.
승객이 원하는 층으로 수직 이동하기 위해 건물 내부에 설치되는 승강기는 통상적으로 사람이 탑승하는 공간인 승강카, 상기 승강카의 하중을 보상하기 위한 균형추, 상기 승강카와 상기 균형추를 연결하는 권상로프 및 상기 권상로프를 회전시켜 승하강시키는 로프풀리를 포함한 권상기로 구성된다.An elevator, which is installed inside a building to vertically move to a desired floor by a passenger, is a lift car, which is a space where a person boards, a balance weight for compensating a load of the lift car, a hoisting rope connecting the lift car and the balance weight, and the It consists of a hoist including a rope pulley for rotating and lifting the hoisting rope.
승강기는 사용 빈도 및 기간이 증가함에 따라 권상로프 및 로프풀리가 노후화되어 승강카의 최대 견인력이 감소하게 된다. 따라서 안전을 위해 주기적으로 승강기의 유지관리 및 보수작업이 필요하다.As the frequency and duration of the elevator increase, the hoisting ropes and rope pulleys age and the maximum pulling power of the elevator car decreases. Therefore, it is necessary to maintain and maintain the elevator periodically for safety.
이를 위해 종래에는 비어있는 승강카에 정격하중에 대응하는 분동을 실어 정상 운행 여부를 확인하였으나, 이와 같은 방법으로는 정확한 견인력을 측정하기 어려울 뿐만 아니라 무거운 분동을 운반해야하므로 작업자의 위험을 초래하고, 측정시간도 오래 걸리는 등의 문제점이 있었다.To this end, in the prior art, a weight corresponding to the rated load was loaded on an empty elevator car to check normal operation.However, in this way, it is not only difficult to measure accurate traction force, but also carries heavy weight, which causes a worker's danger. There was a problem that the measurement takes too long.
이에 무부하 상태의 승강카를 들어올릴 때, 로프풀리와 권상로프 간의 정지마찰계수를 연산하여 권상로프의 견인력을 산출하는 승강기 견인력 측정방법이 제시되었다(특허 제10-1487623호).Therefore, when lifting a hoist car in a no-load state, an elevator traction force measuring method for calculating a traction force of a hoisting rope by calculating a static friction coefficient between a rope pulley and a hoisting rope has been proposed (Patent No. 10-1487623).
그러나 종래 특허는 상기 권상로프의 슬립 직전의 시점에서 로프풀리와 권상로프에 의한 최대정지마찰계수를 연산하여 측정하므로 측정조건이 까다롭고, 구간에 따라 권상로프의 마모정도가 다를 수 있어 오차가 커지는 문제점이 있다.However, the conventional patent is calculated by calculating the maximum stop friction coefficient by the rope pulley and the hoisting rope at the point just before the hoisting rope slip, so the measurement conditions are difficult, and the degree of wear of the hoisting rope may vary depending on the section, resulting in a large error. There is a problem.

상기 승강기 견인력 측정장치(1)는 도 1에 도시된 바와 같이, 승강기의 운행을 정지시킨 상태에서 권상기의 출력축에 결합되는 도르래인 로프풀리(S, sheave)를 승강카(car)가 상승되는 방향으로 회전시켜 권상로프(R)에 발생되는 장력을 견인력으로 측정하는 것으로, 측정 방법에 따라 복수 개의 권상로프(R)를 각각 모두 측정할 수도 있고, 혹은 복수 개의 권상로프(R) 중 견인력이 가장 낮아보이는 것을 측정하여 전체 견인력을 추정하는 방법을 사용할 수 있다. As shown in FIG. 1, the elevator traction force measuring device 1 is a direction in which the elevator car pulls up a pulley rope pulley (S, sheave) coupled to the output shaft of the hoisting machine in a state in which the elevator is stopped. By measuring the tension generated in the hoist rope (R) by the traction force, and depending on the measuring method, it is also possible to measure each of the plural hoist ropes (R), or the traction force of the plurality of hoist ropes (R) A method of estimating overall traction can be used by measuring what looks low.
도 4에서 도시된 바와 같이, 승강기 견인력 측정장치(1)에는 제1로프(r1)와 제2로프(r2)가 각각 상부하우징(11) 일측에 형성된 제1로프인출공(111)과 하부하우징(13) 일측에 형성된 제2로프인출공(131)에서 인출되도록 결합된다.As shown in FIG. 4, the elevator traction force measuring apparatus 1 includes a first rope drawing hole 111 and a lower housing each having a first rope r1 and a second rope r2 formed on one side of the upper housing 11, respectively. (13) is coupled to be drawn out from the second rope drawing hole 131 formed on one side.
도 1에서 볼 수 있는 바와 같이, 견인력 측정시 승강기가 정지된 상태에서 상기 제1로프(r1)는 승강카(car)와 균형추를 연결시켜주는 권상로프(R)에 고정된 로프클램프(C, rope clamp)에 결합되고, 제2로프(r2)는 엘리베이터실 천장에 고정되게 설치되는 고정플레이트(P)나 건물 벽체와 같이 움직이지 않는 고정체에 결합된다.As can be seen in Figure 1, the first rope (r1) is a rope clamp (C, fixed to the hoisting rope (R) that connects the lifting car (car) and the balance weight in the state in which the elevator is stopped when the traction force is measured It is coupled to a rope clamp, the second rope (r2) is coupled to a stationary plate (P) which is fixed to the ceiling of the elevator room or a stationary stationary, such as building walls.
이때, 제1로프(r1) 및 제2로프(r2)는 승강기 견인력 측정장치(1)를 권상로프(R) 측으로 최대한 밀착시켜 측정 오차를 줄이기 위해 폭이 넓은 띠 형상의 로프를 사용하며, 이를 위해 제1로프인출공(111) 및 제2로프인출공(131)은 띠 형상의 로프가 수용되도록 상부하우징(11) 및 하부하우징(13)의 폭방향으로 장홈으로 형성하는 것이 바람직하다.At this time, the first rope (r1) and the second rope (r2) uses a wide belt-shaped rope to reduce the measurement error by closely contacting the elevator traction force measuring device (1) to the hoisting rope (R) side, this To this end, the first rope drawing hole 111 and the second rope drawing hole 131 may be formed as long grooves in the width direction of the upper housing 11 and the lower housing 13 to accommodate the rope-shaped rope.
도 3에서 볼 수 있는 바와 같이, 상기 상부하우징(11)의 로드셀수용부(113) 내에는 로드셀(12, load cell)의 상단이 고정되는데, 상기 로드셀(12)의 하단에는 가압에 의해 하중을 측정하는 로드셀센서부(121)가 구비된다.3, the upper end of the load cell 12 is fixed in the load cell accommodating part 113 of the upper housing 11, and a load is applied to the lower end of the load cell 12 by pressurization. The load cell sensor unit 121 to measure is provided.
상기 하부하우징(13) 내에는 상기 로드셀(12)과 대응되는 위치에 고정되어 상단이 상기 로드셀센서부(121)를 가압하는 가압구(133)가 고정 결합된다.In the lower housing 13, a pressure port 133 fixed to a position corresponding to the load cell 12 and pressurizing the load cell sensor unit 121 is fixedly coupled.
상기 가압구(133) 상부는 로드셀센서부(121)와의 접촉면적을 줄여 측정 오차를 최소화하기 위해 원뿔 형상으로 형성하는 것이 바람직하다.The upper portion of the pressure port 133 is preferably formed in a conical shape in order to reduce the contact area with the load cell sensor unit 121 to minimize the measurement error.
상부하우징(11)과 하부하우징(13)의 양측에는 각각 대응되는 위치에 힌지핀결합공(112, 132)이 형성되고, 상기 힌지핀결합공(112, 132)에는 힌지핀(14)이 관통 결합되어 상부하우징(11)과 하부하우징(13)이 힌지핀(14)을 중심으로 회전 가능하게 구성된다.Hinge pin coupling holes 112 and 132 are formed at both sides of the upper housing 11 and the lower housing 13, respectively, and hinge pins 14 penetrate through the hinge pin coupling holes 112 and 132, respectively. Coupled to the upper housing 11 and the lower housing 13 is configured to be rotatable about the hinge pin (14).
따라서 승강기의 견인력 측정을 위해 승강카(car)가 상승하도록 로프풀리(S)를 수동으로 회전시켜 권상로프(R)가 상승 이동되면 권상로프(R)가 제1로프(r1)를 당겨 제1로프(r1) 및 제2로프(r2)가 각각 인출되는 상부하우징(11)과 하부하우징(13)의 일측이 서로 벌어지게 된다. Therefore, when the hoisting rope R is moved upward by manually rotating the rope pulley S to lift the hoisting car, the hoisting rope R pulls the first rope r1 to measure the traction force of the elevator. One side of the upper housing 11 and the lower housing 13 from which the rope r1 and the second rope r2 are drawn out are opened.
즉, 상부하우징(11)과 하부하우징(13)의 전방은 힌지핀(14)을 중심으로 간격이 서로 벌어지게 되고, 로드셀(12)과 가압구(133)가 구비된 상부하우징(11)과 하부하우징(13)의 후방은 힌지핀(14)을 중심으로 간격이 서로 오므려지게 되면서 가압구(133)가 로드셀(12)의 로드셀센서부(121)를 가압하여 권상로프(R)의 견인력이 측정된다.That is, the front of the upper housing 11 and the lower housing 13 is spaced apart from each other around the hinge pin 14, the upper housing 11 and the load cell 12 and the pressing port 133 and As the rear of the lower housing 13 is spaced around the hinge pin 14, the pressure port 133 presses the load cell sensor unit 121 of the load cell 12 to pull the lifting rope (R). This is measured.
상기 힌지핀(14)의 위치는 승강기 견인력과 로드셀(12) 용량의 상대적 크기를 고려하여 결정된다.The position of the hinge pin 14 is determined in consideration of the lift traction and the relative size of the load cell 12 capacity.
이때, 제1로프(r) 및 제2로프(r2)가 힌지핀(14)을 중심으로 비대칭으로 결합될 경우, 견인력 작용시 상하로 힘의 분력이 발생하여 승강기 견인력 측정장치(1)가 기울어지게 되므로 측정장치(1) 전방의 견인력이 작용하는 선과 후방의 로드셀(12)과 가압구(131)의 작용선이 평행하지 않게 되어 견인력 측정값에 오차가 발생하는 문제점이 있다.At this time, when the first rope (r) and the second rope (r2) is asymmetrically coupled around the hinge pin (14), when the traction force is applied, the force component of the force is generated up and down, the elevator traction force measuring device (1) is inclined As a result, the line of the traction force in front of the measuring device 1 and the line of action of the load cell 12 and the pressure port 131 in the rear are not parallel to each other, thereby causing an error in the traction force measurement value.
따라서 본 발명에서는 제1로프인출공(111)과 제2로프인출공(131)을 힌지핀(14)을 중심으로 상하 대칭되게 구성하여 제1로프인출공(111)과 제2로프인출공(131)에 각각 결합되는 제1로프(r1) 및 제2로프(r2)가 상하 대칭으로 인출되도록 함으로써 견인력 작용시 측정장치(1)가 기울어지지 않고 수평을 유지하게 되고, 이에 따라 힌지핀(14) 후방에 위치한 로드셀(12)에서 오차 없이 견인력을 측정할 수 있게 된다.Therefore, in the present invention, the first rope drawing hole 111 and the second rope drawing hole 131 are configured to be symmetrically up and down about the hinge pin 14 to form the first rope drawing hole 111 and the second rope drawing hole ( The first rope r1 and the second rope r2 respectively coupled to the 131 are pulled up and down symmetrically so that the measuring device 1 does not tilt when the traction force is applied, thereby maintaining horizontality, and thus the hinge pin 14 In the load cell 12 located at the rear side, the pulling force can be measured without error.

도 4 및 도 5에서 볼 수 있는 바와 같이, 상기 상부하우징(11)은 하부하우징(13) 내에 수납되도록 구비되고, 상기 상부하우징(11)의 힌지핀결합공(112) 전방 쪽 양측 상단에는 하부하우징(13)의 양측 상단에 걸리는 스토퍼부(114)가 양측으로 돌출 형성될 수 있다.As can be seen in Figures 4 and 5, the upper housing 11 is provided to be received in the lower housing 13, the upper end of the hinge pin coupling hole 112 of the upper housing 11, the lower side Stopper portions 114 which are caught on both upper ends of the housing 13 may protrude to both sides.
상기 상부하우징(11)은 양측이 하부하우징(13) 내측에 밀착되도록 하부하우징(13) 내에 수납되며, 상부하우징(11) 전방 양측 상단에는 스토퍼부(114)가 돌출 형성되는데, 도 5의 (a)에 도시된 바와 같이 상기 스토퍼부(114)는 권상로프(R) 상승에 의한 견인력 측정 전 상태에서 하부하우징(13)의 상단에 걸리도록 구성되어 승강기 견인력 측정장치(1)의 초기 위치를 고정하게 된다.The upper housing 11 is accommodated in the lower housing 13 so that both sides are in close contact with the inside of the lower housing 13, and the stopper portion 114 protrudes from both upper ends of the front housing 11 and is formed to protrude. As shown in a), the stopper part 114 is configured to be caught by the upper end of the lower housing 13 in the state before the pulling force measurement by the lifting rope R, and thus the initial position of the elevator pulling force measuring device 1 is determined. It will be fixed.
상기 스토퍼부(114)는 상부하우징(11)의 힌지핀결합공(112) 후방 측까지 연장 형성되되, 스토퍼부(114)의 후방 측은 하부하우징(13)의 양측 상단과 일정 간격 이격되도록 형성될 수 있다.The stopper part 114 extends to the rear side of the hinge pin coupling hole 112 of the upper housing 11, and the rear side of the stopper part 114 may be formed to be spaced apart from the upper end of both sides of the lower housing 13 by a predetermined interval. Can be.
도 5의 (a)에 도시된 바와 같이, 상기 상부하우징(11) 후방까지 연장 형성된 스토퍼부(114)는 견인력 측정 전 상태에서 하부하우징(13)의 상단과 일정 간격 이격된 상태를 유지하게 된다.As shown in (a) of FIG. 5, the stopper part 114 extending to the rear of the upper housing 11 maintains a state spaced apart from the upper end of the lower housing 13 at a predetermined distance before the measurement of the traction force. .
그러다가 권상로프(R) 상승에 의해 견인력 작용시 도 5의 (b)에 도시된 바와 같이, 승강기 견인력 측정장치(1)의 전방은 벌어지게 되고 후방은 오므려지게 된다.Then, as shown in Figure 5 (b) when the traction force by the lifting of the lifting rope (R), the front of the elevator traction force measuring device 1 is opened and the rear is closed.
이때, 상기 승강기 견인력 측정장치(1)의 후방이 일정 길이 오므려지게 되면 상기 스토퍼부(114)의 후방이 하부하우징(13)의 상단에 걸려 더 이상 오므려지지 않게 된다.At this time, when the rear of the elevator traction force measuring device 1 is retracted for a certain length, the rear of the stopper 114 is caught on the upper end of the lower housing 13 so that it is no longer retracted.
따라서 권상로프(R)의 과도한 상승으로 인해 상부하우징(11)과 하부하우징(13)이 서로 허용 범위 이상으로 회전되어 로드셀(12)이 손상되는 것을 방지할 수 있다.Therefore, the upper housing 11 and the lower housing 13 may be rotated beyond the allowable range due to excessive lifting of the hoisting rope R, thereby preventing the load cell 12 from being damaged.
도 4에 도시된 바와 같이, 상기 제1로프인출공(111) 및 제2로프인출공(131)은 각각 상부하우징(11)과 하부하우징(13)의 전방 일측에 형성될 수 있다.As shown in FIG. 4, the first rope drawing hole 111 and the second rope drawing hole 131 may be formed at one front side of the upper housing 11 and the lower housing 13, respectively.
견인력 측정치의 정확도를 높이기 위해서는 승강기 견인력 측정장치(1)가 권상로프(R)에 밀착되어 권상로프(R)의 운동방향과 제1로프(r1) 및 제2로프(r2)의 운동방향이 일치하도록 하는 것이 바람직하다.In order to increase the accuracy of the traction force measurement, the elevator traction force measuring device 1 is in close contact with the hoisting rope R so that the movement direction of the hoisting rope R coincides with the movement direction of the first rope r1 and the second rope r2.
