곡률반경을 조절 생산할 수 있는 엘리베이터 보정 체인의 제조방법 및 그 방법으로 제조된 엘리베이터 보정 체인Manufacturing method of elevator correction chain which can produce the curvature radius and elevator correction chain manufactured by the method
본 발명은 곡률반경을 조절 생산할 수 있는 엘리베이터 보정 체인의 제조방법에 관한 것으로서, 보다 상세하게는, 체인의 외부면을 폴리에스터사를 이용한 편직 방법으로 피복하되 편직 밀도의 조절을 통해 곡률반경을 조절 생산할 수 있는 엘리베이터 보정 체인의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing an elevator correction chain capable of controlling and producing a curvature radius, and more particularly, the outer surface of the chain is coated with a knitting method using a polyester yarn, but the curvature radius is adjusted by adjusting the knitting density. It relates to a method of manufacturing an elevator correction chain that can be produced.
일반적으로 엘리베이터 보정 체인은 도 1에 도시한 바와 같이 엘리베이터 케이지(cage)의 하측과 카운트 웨이트(count weight)의 하측에 상호 연결되어 엘리베이터 케이지가 최상부 또는 최하부로 이동될 때 그 엘리베이터 케이지 상측과 카운트 웨이트의 상측에 서로 연결되어 있는 와이어 로프의 이동에 따른 무게의 불균형을 보정해 주는 역할을 한다. In general, the elevator calibration chain is interconnected to the lower side of the elevator cage and the lower side of the count weight as shown in FIG. 1 so that the elevator cage upper side and the count weight when the elevator cage is moved to the top or bottom side. The upper side of the role of correcting the weight imbalance due to the movement of the wire rope connected to each other.
이러한 엘리베이터의 보정 체인은 다수의 금속재 고리가 상호 연결된 링크형 체인이 주로 적용되고 있는데, 이는 고리 상호간의 연결부위에서 움직임에 따른 소음 발생의 문제점이 있었고, 체인은 여유를 두고 길게 형성되는 반면 구속력이 없어 불규칙하게 유동되고 이에 체인이 엘리베이터의 승강로의 콘크리트 벽면에 부딪히면 충격에 따른 소음이 발생하는 문제점도 있었다.This elevator compensation chain is mainly applied to the link-type chain in which a plurality of metal rings are interconnected, which has a problem of noise generated by the movement of the link between the rings.,Chain is On the other hand, it is formed long with a margin, but there is a problem that noise is generated due to the impact when the chain hits the concrete wall of the elevator hoistway because there is no restraining force.
상기한 문제점을 해소하기 위하여 선행된 기술로, 1) 마닐라 로프 삽입형 보정 체인과, 2) 합성수지 수축피복형 보정 체인과, 3) 합성수지 침지피복형 보정 체인과, 4) 합성수지 압출피복형 보정체인 등이 사용되고 있다.In order to solve the above problems, 1) Manila rope insertion correction chain, 2) Synthetic resin shrink coating correction chain, 3) Synthetic resin immersion coating correction chain, 4) Synthetic resin extrusion coating correction chain, etc. Is being used.
1) 마닐라 로프 삽입형 보정 체인1) Manila Rope Insertion Correction Chain
마닐라 로프 삽입형 보정 체인은 도 2에 도시한 바와 같이 보정 체인의 고리와 고리사이에 마닐라 로프를 통과시켜서 고리 상호간 서로 부딪히는 현상을 방지하고 그에 따른 소음을 방지하기 위한 것이나, 상기 마닐라로프를 보정 체인의 고리와 고리사이에 통과시키는 작업은 순수 수작업으로 이루어지고 있으므로 공수가 많이 소요되고 작업시 마닐라 로프로부터 미세한 침상의 마닐라가루가 날려 작업자의 건강에 해를 끼칠 뿐 아니라, 마닐라로프를 보정 체인의 고리에 끼우는 작업도중에 보정 체인의 부식방지를 위해 피막처리된 아스팔트층이 상기 마닐라로프와의 마찰로 인해 벗겨지므로써 부식발생의 원인이 되었다. 또한, 마닐라로프 삽입형 보정 체인은 곡률반경이 매우 좁고, 'V'자형으로 꺾이기 때문에 가이드 바 등 구조물에 부딪혀서 제품의 파손 및 심한 소음을 발생시키는 문제점도 있었다. Manila rope insertion type correction chain is to prevent the collision between the rings and the noise between each other by passing the manila rope between the loop and the ring of the correction chain, as shown in Figure 2, but the manila rope of the correction chain The operation between the ring and the ring is made by pure hand work, which requires a lot of air and fine needles from the manila rope Not only does manila powder blow to harm worker's health, but also during the work of inserting manila rope into the ring of the correction chain, the coated asphalt layer is peeled off due to friction with the manila rope during corrosion of the correction chain. It caused the occurrence. In addition, the manila rope insertion type correction chain has a very small radius of curvature, and because it is bent in a 'V' shape, it has a problem of causing damage to the product and severe noise by hitting a structure such as a guide bar.
2) 합성수지 수축피복형 보정 체인2) Synthetic resin shrink coating type correction chain
합성수지 수축피복형 보정 체인은 도 3에 도시한 바와 같이 용융된 합성수지를 보정 체인에 입힌 후 냉각시켜서 보정 체인에 합성수지 피복처리를 한 것으로, 합성수지를 보정 체인에 피복하기 위한 작업공정이 간단하고 원료비가 비교적 저렴한 장점이 있으나, 보정 체인의 잦은 움직임으로 인해 고리와 고리의 연결부위 피복이 쉽게 갈라지거나 벗겨지고, 동절기 기온 변화에 따른 피복손상 과다발생의 문제점이 있었다.Synthetic resin shrink coating type correction chain is made by coating molten synthetic resin on the correction chain and cooling the synthetic chain as shown in Fig. 3, and the synthetic chain is coated on the correction chain. Although there is a relatively inexpensive advantage, due to the frequent movement of the correction chain, the coating of the ring and the connecting portion of the ring is easily cracked or peeled off, there was a problem of excessive damage to the coating due to winter temperature changes.
3) 합성수지 침지피복형 보정 체인 3) Synthetic resin immersion coating correction chain
합성수지 침지피복형 보정 체인은 도 4에 도시한 바와 같이 내부가 중공된 원통 형태의 합성수지 내부에 보정 체인이 내포되도록 형성한 것으로, 견고하고 반영구적인 장점은 있으나, 현재 실정은 고가의 완제품 자체가 전량 수입에 의존되고 있는 상황이다.Synthetic resin immersed coating type correction chain is formed so that the correction chain is contained inside the synthetic resin hollow cylinder as shown in Figure 4, there is a strong and semi-permanent advantage, but the current situation is that the expensive finished product itself The situation depends on income.
또한, 곡률 반경이 크고 엘리베이터 케이지에 고정이 어려울 뿐 아니라 엘리베이터의 운행 시작과 정지 동작에서 케이지의 미세한 진동에도 반동하여 불규칙한 움직임이 발생하고, 그로 인해 주변 구조물에 강한 충격을 주는 등의 문제점이 있었다.In addition, the radius of curvature is large, it is difficult to fix the elevator cage, and also irregular movement occurs due to the reaction of the minute vibration of the cage in the start and stop operation of the elevator, resulting in a strong impact on the surrounding structure.
4) 합성수지 압출피복형 보정 체인4) Synthetic resin extrusion coating correction chain
합성수지 압출피복형 보정 체인은 도 5에 도시한 바와 같이 용융된 합성수지를 보정 체인에 압출 방식으로 피복 후 체인과 피복층의 내부공간을 진공흡착방법으로 밀착시켜서 보정 체인에 합성수지를 피복처리 한 것으로, 합성수지를 보정 체인에 피복하기 위한 압출 작업공정으로 생산속도를 증대시키고 엘리베이터 운행 시 발생하는 소음을 저감시키는 장점이 있으나, 합성수지의 용융 온도차에 따른 피복층의 두께가 일정하지 않을 경우 단위중량과 곡률반경이 불일치해지고, 압출 피복 시에 링크 체인의 상,하,좌,우 유격으로 인하여 편심을 일정하게 생산하기 어려워 비틀림 현상이 발생되며, 진공흡착 불량 시에 피복 내부에 공기층이 형성되어 체인과 합성수지의 밀착도가 떨어지면서 습기에 의한 체인의 부식 또는 그 부위에 피로에 의한 파손이 쉽게 발생할 수 있는 문제점이 있었다.The synthetic resin extrusion coating type correction chain is coated with molten synthetic resin by extrusion method as shown in FIG. 5, and then the synthetic resin is coated on the correction chain by closely contacting the inner space of the chain and the coating layer by a vacuum adsorption method. It is an extrusion process to coat the chain to the correction chain, which increases the production speed and reduces the noise generated when the elevator is running.However, the unit weight and the radius of curvature do not match when the thickness of the coating layer is not constant due to the melting temperature difference of the synthetic resin. When extruded coating, it is difficult to produce eccentricity constantly due to the top, bottom, left and right clearances of the link chain, and a torsion phenomenon occurs. As the chain falls, corrosion of the chain due to moisture or breakage due to fatigue There was a problem that could easily occur.
또한, 엘리베이터 보정 체인에는 승강로의 조건에 따라 서로 다른 곡률반경이 요구된다. 즉, 곡률반경이란 엘리베이터 보정 체인이 굽어지는 부위에 대한 반지름을 말하는 것으로 주로 중저속용(60m/min ~ 105m/min) 엘리베이터의 경우 75mm ~ 200mm의 곡률반경이 요구되며, 고속용(120m/min 이상) 엘리베이터의 경우 201mm ~ 350mm의 곡률반경이 요구된다. In addition, different curvature radii are required for elevator correction chains depending on the conditions of the hoistway. That is, the radius of curvature refers to the radius of the area where the elevator correction chain is bent. In the case of medium and low speed elevators (60 m / min to 105 m / min), a radius of curvature of 75 mm to 200 mm is required. In the case of elevators, the radius of curvature of 201mm ~ 350mm is required.
공간의 효율성을 위해 점차 좁아지는 승강로의 조건으로 엘리베이터 기계장치와 승강로 벽면과의 거리는 가까워지고 있으며, 이로 인해 엘리베이터 운행 시 보다 균일한 곡률반경 조건을 지닌 보정 체인이 요구되고 있다.As the space for elevators becomes narrower for space efficiency, the distance between the elevator mechanism and the walls of the elevator tracks is getting closer, which demands a correction chain with a more uniform curvature radius during operation of the elevator.
그러나, 기존의 엘리베이터 보정 체인에서는 이와 같은 다양한 승강로 조건에 대응하는 차별화된 곡률반경을 형성할 수 없기 때문에 승강로 조건에 적합하지 않은 곡률반경을 갖는 보정 체인이 적용되는 사례가 빈번하였고, 이러한 곡률반경이 부적합한 조건의 엘리베이터 보정 체인은 승강로 내부에서 구조물에 부딪혀 제품의 파손 및 심한 소음을 발생시키는 등의 문제점을 야기시켰다.However, in the existing elevator correction chain, it is not possible to form a differentiated curvature radius corresponding to such various hoistway conditions, and thus, a correction chain having a curvature radius not suitable for the hoistway condition is frequently applied. Inadequate elevator compensation chains can cause problems such as product damage and loud noises by hitting structures inside the hoistway.
따라서, 본 발명은 상술한 종래기술의 문제점을 해결하기 위해 안출된 것으로서, 기존의 엘리베이터 보정 체인보다 향상된 성능을 제공하면서도 각기 다른 승강로 조건에 대응하여 구분된 곡률반경으로 맞춤 생산할 수 있는 엘리베이터 보정 체인의 제조방법을 제공하는데 그 목적이 있다. Accordingly, the present invention has been made to solve the above-described problems of the prior art, the elevator compensation chain of the elevator can be customized to produce a different curvature radius corresponding to different elevator conditions while providing improved performance than the existing elevator correction chain The purpose is to provide a manufacturing method.
상술한 목적을 달성하기 위한 기술적 수단으로, 본 발명은 편직장치를 이용하여 엘리베이터 보정 체인의 외부를 편직물로 피복처리하되, 고강도 산업용 폴리에스터사로 편직하여 내구성을 향상시키고, 구분된 편직 조건에 따라 편직 밀도를 조절함으로써 각기 다른 승강로 조건에 대응하여 서로 다른 곡률반경을 갖는 엘리베이터 보정 체인의 제조방법을 제공하도록 한다.As a technical means for achieving the above object, the present invention is to cover the outside of the elevator correction chain with a knitted fabric by using a knitting device, but by knitting with high-strength industrial polyester yarn to improve durability, knitting according to the separate knitting conditions By adjusting the density, it is possible to provide a method for manufacturing an elevator correction chain having different radii of curvature in response to different hoist conditions.
본 발명에 따른 곡률반경을 조절 생산할 수 있는 엘리베이터 보정 체인의 제조방법에 의하면, 보정 체인의 고리와 고리가 부딪혀 발생되는 소음을 방지하고 충격완화 작용 및 안전사고를 예방할 수 있는 엘리베이터 보정 체인을 제공하되, 중저속용(60m/min ~ 105m/min) 및 고속용(120m/min 이상) 엘리베이터에서 요구하는 각각의 곡률반경에 대응하도록 엘리베이터 보정 체인을 맞춤 생산할 수 있는 효과가 있다.According to the manufacturing method of the elevator correction chain capable of adjusting and producing the radius of curvature according to the present invention, to provide an elevator correction chain that can prevent the noise generated by colliding with the ring and the ring of the correction chain, and to prevent the impact relief action and safety accidents. In addition, there is an effect that can be customized to meet the elevator curvature chain to meet the curvature radius required by the low and medium speed (60m / min ~ 105m / min) and high speed (120m / min or more) elevator.
또한, 산업용 고강도 폴리에스터사를 이용한 편직 방법으로 피복된 엘리베이터 보정 체인은 내구성 및 내습성이 강하고, 제조 비용을 감소할 수 있으며, 다양한 색상으로의 편직이 가능하기에 미려한 외관을 형성할 수 있고, 자외선 노출에 대한 색 변질이 적은 효과도 있다.In addition, the elevator correction chain coated by the knitting method using the industrial high-strength polyester yarn is durable and moisture resistance, can reduce the manufacturing cost, can form a beautiful appearance to be knitted in various colors, There is also a small effect of color degradation on UV exposure.
또한, 다수의 보빈이 지그재그 형태로 서로 엇갈려 이동하면서 편직을 하게 되면 사용 중 편직사의 부분적 손상이 발생하더라도 올 풀림 현상이 방지될 수 있어 사용 수명이 연장되는 효과도 있다.In addition, when a plurality of bobbins are staggered and moved in a zigzag form, even if partial damage occurs to the knitting yarn during use, the unwinding phenomenon may be prevented, thereby extending the service life.
