로프식 엘리베이터는 최상층에 엘리베이터를 구동시키는 기계실이 마련되며, 기계실의 권상기(traction machine)는 객실(car)과 균형추(balance weight)를 로프로 연결하여 객실을 상하로 이동시킨다. 이러한 기계실은 높이 제한과 같이 몇몇 이유로 건축물에 불리하게 작용할 수가 있다. The rope elevator has a machine room for driving the elevator on the top floor, and a traction machine of the machine room moves the cabin up and down by connecting a car and a balance weight with a rope. Such a machine room may be detrimental to the building for several reasons, such as height limitations.
최근 초고층 건물들의 건설 붐과 함께 고성능 엘리베이터가 등장하여 약 60km/h(1000m/min)이상의 빠른 속도로 움직이는 초고속 엘리베이터가 개발되고 있다. 또한 엘리베이터 2대가 상하로 연결되어 수송능력을 향상시킨 더블데크 엘리베이터도 있으며, 하나의 엘리베이터 통로에 2대의 엘리베이터가 독립적으로 동작하는 트윈 엘리베이터도 있다.Recently, high-performance elevators have emerged along with the construction boom of high-rise buildings, and high-speed elevators moving at a high speed of about 60 km / h (1000 m / min) or more have been developed. There are also double-deck elevators that have two elevators connected up and down to improve their transport capacity, and there are twin elevators that operate two elevators independently in one elevator passage.
초고층 건물들은 수직 동선의 수송을 원활하게 하기 위하여 더욱 더 빠르게 움직이는 엘리베이터를 요구하고 있다. 엘리베이터의 속도를 높이려면 속도의 제곱에 비례하는 장력이 와이어에 가해지며, 고속 엘리베이터일수록 큰 장력을 지탱할 수 있어야 한다. 따라서 로프의 단면적이 더 커지게 되고 로프의 무게도 늘어나게 된다. 게다가 초고층빌딩의 긴 이동거리만큼 로프의 길이도 길어져야 하기 때문에, 속도 외에도 로프 자신의 무게의 증가로 로프는 더욱 굵어져야 한다. 초고층 건물에서는 결국 엘리베이터의 객실보다 로프가 더 무거울 수도 있다.Skyscrapers require faster moving elevators to facilitate vertical copper transportation. To speed up an elevator, tension is applied to the wires that is proportional to the square of the speed, and the higher the elevator, the greater the tension. Therefore, the cross section of the rope becomes larger and the weight of the rope increases. In addition, because the length of the rope must be as long as the long distance of the skyscraper, the rope must be thicker by increasing the weight of the rope itself. In skyscrapers, the rope may be heavier than the elevator cabin.
참고로, 엘리베이터는 45m/min 이하로 이동하는 저속 엘리베이터, 60~105m/min으로 이동하는 중속(normal) 엘리베이터, 약 120~300m/min으로 이동하는 고속 엘리베이터, 및 약 360m/min 이상으로 이동하는 초고속 엘리베이터로 구분될 수 있다.For reference, the elevator is a low-speed elevator moving to less than 45m / min, a normal speed elevator moving to 60 ~ 105m / min, a high-speed elevator moving to about 120 ~ 300m / min, and moving to about 360m / min or more It can be classified as a high speed elevator.
실제로 버즈두바이 빌딩에 설치된 초고속 엘리베이터 중에는 로프 무게만 20톤(t)에 달한다. 게다가 균형추의 중량까지 더해지므로 엘리베이터를 고속으로 가속시키는 데는 의외로 큰 동력을 필요로 하게 된다. 결국 로프로 인해 잔뜩 무거워진 엘리베이터를 초고속으로 가속하여야 하기 때문에, 권상기의 모터 역시 일반 모터보다 현저히 큰 용량으로 제공되어야 한다.In fact, among the high-speed elevators installed in the Buzz Dubai Building, the rope weighs only 20 tons (t). In addition, the weight of the counterweight is added, which requires a great deal of power to accelerate the elevator at high speed. After all, the elevator, which is too heavy due to the rope, must be accelerated at a very high speed, and therefore the motor of the hoist must also be provided with a significantly larger capacity than a general motor.
또한, 로프가 수 백 미터 이상 길어지게 되면 로프가 닳는 정도나 온도변화에 따라 로프의 길이가 달라지므로 정확한 위치에 정지하기 어려워진다. 따라서 와이어로프의 특성이 더욱 까다로워지고 그 제어방법도 복잡하게 된다. In addition, when the rope is lengthened by several hundred meters or more, it becomes difficult to stop at the correct position because the length of the rope varies according to the degree of wear of the rope or the temperature change. Therefore, the characteristics of the wire rope become more difficult and the control method thereof becomes complicated.
종래의 스크류식 엘리베이터는 나사가공을 한 긴 지주를 세우고 너트에 상당하는 슬리브를 객실에 설치하는 구조를 이용하고 있다. 스크류식 엘리베이터에서는 지주가 회전하는 것에 의해 객실을 승강시키기 때문에, 소형의 간이 엘리베이터에 이용되거나 유체의 이동이 어려울 때 사용하고 있다.Conventional screw-type elevators utilize a structure in which a long post that is threaded is erected and a sleeve corresponding to the nut is installed in the cabin. In a screw-type elevator, the cabin is moved up and down by rotating the prop, so that it is used in a small simple elevator or when the fluid is difficult to move.
이미 100층 이상의 초고층 빌딩에서는 기존의 로프식 엘리베이터 대신 로프리스(ropeless) 엘리베이터가 이용될 것이라는 예상도 있으며, 이와 관련하여 미국특허 제5234079호에는 리니어모터를 이용한 엘리베이터가 개시되어 있다. 하지만, 이들 리니어식 엘리베이터는 로프 없이 허공에 뜬 상태로 이동하기 때문에, 안전장치를 3중 4중으로 견고히 하여야 하며, 물리적 접촉이 없어 수평 이동이 가능하다고 하지만 상용화를 위해서는 고객의 인식과 경제성 등 풀어야 할 요소가 적지 않아 매우 극복하기 어렵다. Already, skyscrapers of more than 100 stories are expected to use ropeless elevators instead of conventional rope elevators. US Patent No. 5234079 discloses an elevator using a linear motor. However, since these linear elevators move in the air without a rope, the safety device must be firmly tripled and tripled, and horizontal movement is possible because there is no physical contact. There are not many elements and it is very difficult to overcome.
이와 관련하여, 한국등록특허 제10-1035068호는 "웜기어형 구동부 및 웜기어형 구동부를 이용한 엘리베이터"가 개시되어 있다. 상기 웜기어형 구동부는 웜기어 형상으로 형성된 웜 구동부를 포함하며, 웜 구동부 및 웜 지지부 간의 상호 작용에 의해서 객실부를 상하로 승강시키는 기능을 할 수 있다. In this regard, Korean Patent No. 10-1035068 discloses an "elevator using a worm gear drive and a worm gear drive." The worm gear-type driving unit includes a worm driving unit formed in a worm gear shape, and may function to elevate the cabin part up and down by the interaction between the worm driving unit and the worm supporting unit.
하지만, 상기 웜 구동부는 직경 및 상하 높이가 최소 1m 이상이어야 하므로, 하중이 매우 크고 제작이 쉽지 않다는 문제점이 있다. 또한, 롤러를 사용하여 저저항 접촉을 유지하기 때문에 고속 회전이 있을 경우 원활한 회전을 방해할 수 있는 요소가 일부 존재한다는 문제점도 있다.However, since the worm driving unit should have a diameter and a vertical height of at least 1 m or more, there is a problem that the load is very large and not easy to manufacture. In addition, there is a problem that there is some element that can prevent the smooth rotation when there is a high speed rotation to maintain a low resistance contact using the roller.
본 발명은 웜 구동부를 이용한 로프리스 승강장치를 제공하되, 웜 구동부의 경량화 및 강도 보강을 동시에 구현할 수 있는 승강장치를 제공한다.The present invention provides a ropeless lifting apparatus using a worm driving unit, and provides a lifting apparatus that can simultaneously realize the weight reduction and strength reinforcement of the worm driving unit.
본 발명은 제작이 용이하면서 저렴하고, 내부 부품의 배치를 용이하게 할 수 있는 승강장치를 구현한다. The present invention implements a lifting device that is easy to manufacture and inexpensive and can facilitate the placement of internal components.
본 발명은 정전 등과 같이 사고가 발생하여도 승객을 안전하게 보호할 수 있는 승강장치를 제공한다. 웜 기어체를 사용하는 승강장치는 그 자체만으로도 안전하지만, 승객을 보호한다는 차원에서 더욱 개선된 안전을 제공할 수 있다.The present invention provides a lifting device that can safely protect a passenger even in case of an accident such as a power failure. Lifts using worm gear bodies are safe on their own, but can provide improved safety in terms of protecting passengers.
본 발명의 예시적인 일 실시예에 따르면, 승강장치는 승강통로를 따라 이동하는 객실부, 객실부와 함께 이동하며 회전축이 객실부의 이동경로와 나란한 웜 구동부, 객실부의 이동경로를 따라 승강통로 내에 제공되며 웜 구동부의 치 간격을 주기로 웜 구동부의 웜치와 대응하도록 형성된 다수의 지지 치를 포함하는 웜 지지부를 포함하며, 상기 웜치는 내부 공간이 있는 중공형으로 제공되는 것을 특징으로 한다. According to an exemplary embodiment of the present invention, the elevating device moves along the elevating passage, the moving unit moves along with the cabin, and the rotation axis is provided in the elevating passage along the worm drive, parallel to the moving path of the cabin, the cabin. It includes a worm support portion including a plurality of support teeth formed to correspond to the worm tooth of the worm drive unit at intervals of the tooth of the worm drive unit, characterized in that the worm tooth is provided in a hollow form having an internal space.
상기 웜치가 중공형으로 제공되기 때문에 경량으로 제공되며, 알루미늄이나 마그네슘, 또는 그 합금, 고강도 합성수지를 이용하여 형성되어 강도를 충분히 유지할 수 있다. 또한, 웜치 내부를 중공형으로 형성하여 전자석 모듈과 같이 웜치와 웜 지지부를 간에 인력이나 척력을 제공할 수 있는 부가 모듈, 높이 또는 회전 센서 등을 용이하게 장착할 수가 있다. Since the worm is provided in a hollow form, it is provided at a light weight, and is formed using aluminum, magnesium, or an alloy thereof, a high strength synthetic resin, and can sufficiently maintain the strength. In addition, it is possible to easily mount an additional module, a height or a rotation sensor, etc., which are formed in a hollow form and provide an attractive force or repulsive force between the worm and the worm support, like an electromagnet module.
중공형으로 형성된 웜치의 강도를 보강하기 위해서 웜치 내부에 방사상으로 형성된 수직격벽을 형성할 수 있으며, 이를 위해서 다이캐스팅 등의 방법이 사용될 수가 있다. In order to reinforce the strength of the hollow formed worm tooth can be formed radially formed vertical bulkhead inside the worm tooth, for this purpose, a method such as die casting can be used.
웜 구동부는 웜기어(wormgear) 형태의 몸체를 포함하며, 웜 구동부의 몸체는 등간격으로 배치된 웜 지지부(worm supporting parts)의 지지 치와 맞물려 지지되면서 승강을 위한 힘을 제공할 수 있다. 웜 구동부는 그 자체만으로도 승강에 필요한 힘을 충분히 제공할 수 있으며, 웜 지지부의 지지 치가 약 40cm 간격으로 배열되어 있다고 가정할 때 웜 기어체는 약 900rpm의 회전속도로 초고속 엘리베이터에 적합한 약 360m/min의 속도를 충분히 구현할 수 있다. 물론, 600~1500m/min의 초고속도 역시 충분히 구현이 가능하다. The worm drive unit may include a wormgear-shaped body, and the body of the worm drive unit may be engaged with the support teeth of the worm supporting parts arranged at equal intervals to provide a force for lifting. The worm drive unit alone can provide sufficient force for lifting, and assuming that the support values of the worm supports are arranged at intervals of about 40 cm, the worm gear body is about 360 m / min suitable for high speed elevators at a rotation speed of about 900 rpm. Speed can be implemented sufficiently. Of course, the ultra high speed of 600 ~ 1500m / min can also be fully implemented.
기본적으로 웜 구동부와 웜 지지부 간의 상호 작용에 의해서 객실부를 수직하게 이동시킬 수 있으며, 종래와 같은 로프를 사용하지 않는다. 따라서 초고층 건물에서 사용하여도 로프 무게에 따른 비효율성을 극복할 수 있으며, 수십 톤에 달하는 로프를 움직이지 않아도 되기 때문에 에너지를 효율적으로 사용할 수가 있다. Basically, the cabin part can be vertically moved by the interaction between the worm drive unit and the worm support unit, and a rope as in the prior art is not used. Therefore, it can overcome the inefficiency according to the rope weight even when used in a high-rise building, and can use energy efficiently because it does not have to move tens of tons of rope.
웜 구동부와 웜 지지부 간에는 저저항 접촉이 형성되는 것이 바람직하다. 저저항 접촉을 형성하기 위해 다양한 방법이 사용할 수 있다. 예를 들어, 롤러를 이용한 구름 접촉을 이용할 수도 있으며, 영구 자석이나 전자석 등을 이용하여 자기 부상을 형성할 수도 있다. 롤러 또는 자기 부상 모두 복수개의 치면이 웜 지지치 위를 미끄러지듯이 이동하기 때문에 소음이나 진동 없이 객실부를 이동시킬 수 있는 것은 물론 부품 간의 마모를 방지하여 부품의 수명을 증가시킬 수도 있다.Preferably, a low resistance contact is formed between the worm drive and the worm support. Various methods can be used to form low resistance contacts. For example, rolling contact using a roller may be used, and magnetic levitation may be formed using a permanent magnet, an electromagnet or the like. Both the roller or the magnetic levitation slides over the worm support teeth, so that the moving parts can be moved without noise or vibration, and the life of the parts can be increased by preventing wear between the parts.
본 발명의 예시적인 일 실시예에 따르면, 승강장치는 승강통로를 따라 이동하는 객실부, 상기 객실부와 함께 이동하며 회전축이 객실부의 이동경로와 나란한 웜 기어체를 포함하는 웜 구동부, 객실부의 이동경로를 따라 승강통로 내에 제공되며 웜 기어체의 웜치 간격을 주기로 형성된 다수의 지지 치를 포함하는 웜 지지부, 및 웜 기어체의 회전축에 장착되는 디스크와 상기 디스크에 대응하는 브레이크 패드를 포함하는 브레이크 장치를 포함한다. According to an exemplary embodiment of the present invention, the elevating device is a worm driving unit, a worm driving unit that moves along the lifting passage, the worm drive unit moving along with the cabin and the rotation axis includes a worm gear body parallel to the moving path of the cabin part, the moving path of the cabin part. A worm support portion provided in the elevating passageway and including a plurality of support teeth formed at intervals of worm teeth of the worm gear body, and a brake device including a disk mounted on a rotation shaft of the worm gear body and a brake pad corresponding to the disk. do.
상기 브레이크 패드는 디스크를 양면에서 접하도록 제공되며, 웜 엘리베이터 또는 웜 구동부에 전력이 차단된 상태, 즉 브레이크에 전력이 차단된 상태에서 디폴트로 디스크를 가압하도록 할 수 있다.The brake pad may be provided to contact the disk on both sides, and may press the disk by default in a state in which power is cut off in the worm elevator or the worm driving unit, that is, in a state in which power is cut off in the brake.
본 발명의 승강장치에서 웜 구동부는 경량으로 제공되며, 중공으로 제공되어도 강도를 충분히 보강할 수가 있다. 또한, 웜 구동부의 제작이 용이하면서 저렴하면서, 내부 부품의 배치를 용이하게 할 수 있다.In the hoisting apparatus of the present invention, the worm driving unit is provided at a light weight, and even when provided in a hollow, the worm driving unit can sufficiently reinforce strength. In addition, while the production of the worm drive is easy and inexpensive, it is possible to easily arrange the internal parts.
본 발명의 승강장치는 로프나 와이어를 사용하지 않기 때문에, 로프의 거대한 무게에 따른 비효율성을 개선할 수가 있으며, 초고층 빌딩이나 초고속 엘리베이터일수록 더 큰 에너지 절감 효과를 기대할 수가 있다. Since the lifting device of the present invention does not use a rope or a wire, it is possible to improve the inefficiency according to the huge weight of the rope, and a skyscraper or a high-speed elevator can expect a greater energy saving effect.
높아진 운송 효율만큼 건물 내에서 승강통로의 수를 줄이거나 최적으로 유지할 수 있으며, 승강통로의 줄임을 통해 건물의 내부 공간이 더욱 상대적으로 더 넓어지는 반사 이익을 얻을 수 있다. 즉, 본 발명의 승강장치는 수송효율 증가로 승강통로의 개수를 줄일 수 있고, 각 승강통로가 차지하는 자체 면적을 효율적으로 이용할 수 있으므로, 같은 공간 내에서도 주거 또는 생활 공간을 많이 확보할 수 있다. 건물주로서도 동일한 수송량을 유지하면서 분양공간을 더 많이 확보할 수 있으므로 경제적인 효과도 매우 높다고 할 수 있다.By increasing transportation efficiency, the number of hoistway passages in the building can be reduced or optimally maintained, and the reduction of the hoistway passages can result in a reflection benefit that allows the building's interior space to become more spacious. That is, the lifting device of the present invention can reduce the number of lifting passages by increasing the transportation efficiency, and can efficiently use its own area occupied by each lifting passage, thereby securing a lot of living or living space in the same space. As a building owner, it is possible to secure more pre-sale space while maintaining the same amount of transportation, which is why the economic effect is very high.
본 발명의 승강장치는 정전 등과 같이 사고가 발생하여도 승객을 안전하게 보호할 수 있다. 물론, 구동장치로서 웜 기어체를 사용하기 때문에 그 자체만으로도 안전하지만, 승객을 보호한다는 차원에서 더욱 개선된 안전을 제공할 수 있다.The elevator apparatus of the present invention can safely protect passengers even in an accident such as a power failure. Of course, since the worm gear body is used as the driving device, it is safe by itself, but it can provide more improved safety in terms of protecting passengers.

이하 첨부된 도면들을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하지만, 본 발명이 실시예에 의해 제한되거나 한정되는 것은 아니다. 참고로, 본 설명에서 동일한 번호는 실질적으로 동일한 요소를 지칭하며, 이러한 규칙 하에서 다른 도면에 기재된 내용을 인용하여 설명할 수 있고, 당업자에게 자명하다고 판단되거나 반복되는 내용은 생략될 수 있다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments. For reference, in the present description, the same numbers refer to substantially the same elements, and may be described by referring to the contents described in the other drawings under these rules, and the contents determined to be obvious to those skilled in the art or repeated may be omitted.
도 1은 본 발명의 일 실시예에 따른 승강장치를 설명하기 위한 정면도이며, 도 2는 도 1의 웜 구동부를 설명하기 위한 부분 단면도이고, 도 3은 도 1의 웜치 내부 구조를 설명하기 위한 확대 단면도이다.1 is a front view for explaining a lifting device according to an embodiment of the present invention, Figure 2 is a partial cross-sectional view for explaining the worm drive of Figure 1, Figure 3 is an enlarged cross-sectional view for explaining the internal structure of the worm tooth of Figure 1 to be.
도 1 내지 도 3을 참조하면, 승강장치(100)는 객실부(110), 승강 프레임(120), 웜 구동부(130) 및 웜 지지부(170)를 포함하며, 승강장치(100)의 객실부(110)는 웜 구동부(130) 및 웜 지지부(170) 간의 상호 작용에 의해서 건축물 내의 승강통로를 따라 이동할 수 있다. 승강장치(100)는 독립적인 제어부(180), 에어컨디셔너(185) 및 무선 통신 모듈(190) 등을 더 포함할 수 있으며, 승강장치(100)의 원활한 구동 및 제어를 실행할 수가 있다.1 to 3, the lifting device 100 includes a cabin unit 110, a lifting frame 120, a worm driving unit 130, and a worm support unit 170, and a cabin unit of the lifting device 100. 110 may move along the lifting passage in the building by the interaction between the worm drive unit 130 and the worm support unit 170. The lifting device 100 may further include an independent control unit 180, an air conditioner 185, a wireless communication module 190, and the like, and may smoothly drive and control the lifting device 100.
웜 구동부(130)는 웜기어(wormgear) 형상의 웜기어체(140)를 포함하며, 웜기어체(140)의 외면에는 웜치(teeth)(142)가 형성된다. 웜기어체(140)는 승강장치(100)에 진행 방향과 나란하게 배열된 회전축을 포함하며, 상기 회전축을 중심으로 회전 가능하게 장착된다. 웜기어체(140)의 웜치(142)에 대응하여 승강통로에는 웜 지지부(170)가 제공되며, 본 실시예에서 웜 기어체(140)의 웜치(142) 및 웜 지지부(170)에는 전자석 모듈이 제공되어 상호 척력 또는 인력을 제공할 수 있다. The worm driving unit 130 includes a worm gear body 140 having a wormgear shape. A worm tooth 142 is formed on an outer surface of the worm gear body 140. The worm gear body 140 includes a rotating shaft arranged in parallel with the traveling direction on the elevating device 100 and rotatably mounted about the rotating shaft. The worm support part 170 is provided in the lifting passage corresponding to the worm gear 142 of the worm gear body 140. In the present embodiment, the worm gear 142 and the worm support part 170 of the worm gear body 140 have an electromagnet module. Can be provided to provide mutual repulsion or attraction.
본 실시예에서는 웜치(142)의 저면을 따라 복수의 전자석 모듈이 제공되며, 지지 치(172)의 상면에 역시 척력을 공급하는 전자석 모듈을 제공한다. 하지만, 경우에 따라서는 웜치의 상면에 전자석 모듈을 배치하고 지지 치의 저면에 전자석 모듈을 배치하여 인력으로 저저항 접촉을 형성할 수도 있고, 웜치를 중심으로 상면에서 인력을 제공하고 저면에서 척력을 제공하여 저저항 접촉을 형성하도록 할 수가 있다. In the present embodiment, a plurality of electromagnet modules are provided along the bottom of the worm tooth 142, and an electromagnet module for supplying repulsive force to the top surface of the support tooth 172 is also provided. However, in some cases, the electromagnet module may be disposed on the upper surface of the worm tooth and the electromagnet module may be formed on the bottom surface of the support tooth to form a low resistance contact by the attraction force. To form a low resistance contact.
도시된 바와 같이, 웜 구동부(130)는 승강장치에서 웜기어체(140)를 회전시키며, 웜기어체(140)의 웜치(142)는 웜 지지부(170)와의 척력에 의해서 서로 밀착되지 않고 부상할 수 있는 힘을 받을 수 있다. 웜기어체(140)의 회전에 따라 웜 지지부(170) 상에서 부상된 상태에서 객실부(110)와 함께 미끄러지듯이 상승 또는 하강할 수 있다. As shown, the worm drive unit 130 rotates the worm gear body 140 in the lifting device, the worm gear 142 of the worm gear body 140 may rise without being in close contact with each other by the repulsive force with the worm support unit 170. You can receive the strength that you have. According to the rotation of the worm gear body 140, it may rise or fall as if it slides together with the cabin part 110 in the injured state on the worm support part 170.
객실부(110)는 웜 구동부(130)를 이용하여 승강할 수 있기 때문에, 종래의 로프나 와이어를 사용하지 않으며, 최상층에 권상기나 기계실을 설치할 필요가 없다. 즉, 각 객실부(110)에 상부 또는 하부에 설치되는 웜 구동부(130)를 사용하며, 로프에 의존하지 않고 웜 구동부(130)의 회전을 객실부(110)의 상하 이동으로 전환할 수 있다. Since the cabin 110 can be elevated using the worm drive 130, it does not use a conventional rope or wire, and there is no need to install a hoist or a machine room on the top floor. That is, using the worm driving unit 130 is installed in the upper or lower portion of each compartment 110, it is possible to switch the rotation of the worm drive 130 to the vertical movement of the compartment 110 without depending on the rope. .
따라서, 승강장치(100)의 구동 계통이 간소화되며, 로프를 생략함으로써 초고층 빌딩에 적용되었을 때 거대한 로프의 무게에 대한 부담을 제거할 수가 있다. 또한, 구조적으로도 로프의 원활한 이동 및 균형추 가설에 대한 부담도 제거할 수가 있다. Therefore, the drive system of the elevating device 100 is simplified, and by eliminating the rope, it is possible to eliminate the burden on the weight of the huge rope when applied to the skyscraper. In addition, the structure can also remove the burden on the smooth movement of the rope and counterweight hypothesis.

도 8은 본 발명의 일 실시예에 따른 승강장치를 설명하기 위한 정면도이며, 도 9는 도 8의 브레이크 장치를 설명하기 위한 단면도이고, 도 10은 도 8의 웜 구동부를 설명하기 위한 부분 단면도이다.FIG. 8 is a front view illustrating a lifting device according to an embodiment of the present invention, FIG. 9 is a cross-sectional view for describing the brake device of FIG. 8, and FIG. 10 is a partial cross-sectional view for explaining the worm driving unit of FIG. 8.
도 8 내지 도 10을 참조하면, 승강장치는 전술한 객실부(110), 승강 프레임(120), 웜 구동부(130) 및 웜 지지부(170) 외에도 브레이크 장치(300)를 더 포함한다. 승강장치는 독립적인 제어부(180), 에어컨디셔너(185) 및 무선 통신 모듈(190) 등을 더 포함할 수 있다.8 to 10, the lifting device further includes a brake device 300 in addition to the cabin unit 110, the lifting frame 120, the worm driving unit 130, and the worm supporting unit 170. The lifting device may further include an independent controller 180, an air conditioner 185, a wireless communication module 190, and the like.
웜기어체(140)의 상부 및 하부에 각각 브레이크 장치(300)가 제공된다. 브레이크 장치(300)는 웜기어체(140)의 회전축에서 상부 또는 하부에 제공되는 디스크(310) 및 브레이크 하우징(305) 내부에 장착된 브레이크 패드(320)를 포함한다. 브레이크 패드(320)는 디스크(310)의 양면에 제공되며, 브레이크 패드(320)가 서로 접근하여 디스크(310)의 양면을 가압함으로써 웜기어체(140)의 회전을 정지시킬 수 있다. The brake device 300 is provided on the upper and lower portions of the worm gear body 140, respectively. The brake device 300 includes a disk 310 provided above or below the rotation shaft of the worm gear body 140 and a brake pad 320 mounted inside the brake housing 305. The brake pads 320 may be provided on both surfaces of the disk 310, and the brake pads 320 may approach each other to stop the rotation of the worm gear body 140 by pressing both surfaces of the disk 310.
브레이크 장치(300)는 디스크(310) 및 브레이크 패드(320) 외에도 탄성 가압부(330) 및 솔레노이드와 같이 작동하는 이격부(340)를 포함할 수 있다. 탄성 가압부(330)는 디폴트로 브레이크 패드(320)를 디스크(310)에 밀착시키는 힘을 제공하며, 이격부(340)는 반대로 브레이크 패드(320)을 상호 벌려 디스크(310)로부터 브레이크 패드(320)를 떨어지게 하는 기능을 한다. In addition to the disk 310 and the brake pad 320, the brake device 300 may include an elastic pressing unit 330 and a spacer 340 that works together with the solenoid. The elastic pressing portion 330 provides a force for closely contacting the brake pad 320 to the disk 310 by default, and the spacer 340 conversely spreads the brake pad 320 from each other to separate the brake pad 320 from the disk 310. 320) to fall off.
따라서, 브레이크 장치(300), 즉 이격부(340)에 전원이 인가되면 이격부(340)의 힘이 탄성 가압부(330)를 능가하여 디스크(310)로부터 브레이크 패드(320)를 분리시키며, 전원이 차단되면 탄성 가압부(330)만 작동하여 디스크(310)에 브레이크 패드(320)를 밀착시킬 수 있다. 다시 말하면, 승강장치의 이동을 위해 전원이 인가되면 이격부(340)가 작동하여 브레이크 장치(300)가 웜기어체(140)의 회전을 방해하지 않도록 하지만, 정전이나 사고가 발생하여 전원이 차단되면 탄성 가압부(330)만 작동하여 브레이크 장치(300)가 기본적으로 웜기어체(140)의 회전을 정지시킬 수 있다.Accordingly, when power is applied to the brake device 300, that is, the spacer 340, the force of the spacer 340 exceeds the elastic pressing unit 330 to separate the brake pad 320 from the disk 310. When the power is cut off, only the elastic pressing unit 330 may operate to bring the brake pad 320 into close contact with the disk 310. In other words, when power is applied for the movement of the lifting device, the spacer 340 operates so that the brake device 300 does not interfere with the rotation of the worm gear body 140, but when the power is cut off due to a power failure or an accident, By operating only the pressing unit 330, the brake device 300 may basically stop the rotation of the worm gear body 140.
