A hydraulic working beam support device using a combination of a cylinder and an idle roller.
일반적으로, 도 1과 도 2에 나타낸 바와 같이, 열간압연 가열로의 워킹빔(80)은 연주 슬래브(slab)를 재가열하여 스트립으로 압연하기 위해 고온의 로내에서 슬래브를 입측에서 출측으로 이송시키는 장치로서, 연결된 모터(10), 1차 감속기(20), 구동샤프트(30), 2차 감속기(40), 피니언샤프트(50), 스퍼기어(60) 및 편심휠(70)로 구성된 하부의 기계장치에 의해 구동되는데, 이에 따라 장치의 구성을 위해 넓은 공간이 필요되고, 높이의 제약을 받게 되어 시스템 구성에 어려움이 있으며, 또한 그 적용에 한계가 있고, 다수의 지지점을 형성할 수 없어 중심부에서 하중집중 현상이 발생됨으로써 부품손상에 의한 슬래브 이송중지와 더불어 이에 따른 소재이상에 의한 품질불량이 야기되고 있는 실정이다.In general, as shown in Figs. 1 and 2, the working beam 80 of a hot rolling furnace is an apparatus for transporting the slab from the inlet to the outlet side in a hot furnace for reheating the playing slab and rolling it into a strip. The lower machine consists of a connected motor 10, primary reducer 20, drive shaft 30, secondary reducer 40, pinion shaft 50, spur gear 60 and eccentric wheel 70. It is driven by the device, which requires a large space for the configuration of the device, is restricted by the height, difficult to configure the system, there is also a limitation in the application, and can not form a plurality of support points in the center As load concentration occurs, the slab transfer is stopped due to component damage and quality defects are caused by material abnormalities.
덧붙여, 슬래브를 이송하기 위해 워킹빔은 상승→전진→하강→후진의 사이클 운동을 함에 따라 단계별로 작용하는 힘의 크기와 방향이 다르므로 하나의 장치로 구성하는 것이 어려워 전술한 바와 같이 그 구성이 매우 복잡하였다.In addition, in order to transport the slab, the working beam has a different magnitude and direction of force acting in stages as a cycle of rising → forward → lower → reverse, so that it is difficult to construct a single device. It was very complicated.

상기와 같은 목적을 달성하기 위한 본 발명의 유압을 이용하는 열연 가열로 워킹빔 지지장치는, 열간압연 가열로내에서 슬래브를 이송하는 워킹빔(80) 하부의 지지장치에 있어서, 수직의 유압실린더(140) 상부에 베어링 회전하는 구동휠(110)을 구비시켜 그 상부에 상기 워킹빔(80)을 안착시킴으로써 상하운동과 주행운동이 가능하도록 하고, 상기 유압실린더(140) 주위에 상기 구동휠(110) 부분이 승하강시 가이드되고, 전후진 구동시 수평방향 부하를 견딜 수 있도록 가이드(130)를 구비시켜 구성되는 것을 특징으로 한다.Hot rolling furnace working beam support device using the hydraulic pressure of the present invention for achieving the above object, in the support device of the lower working beam 80 for transporting the slab in the hot rolling furnace, vertical hydraulic cylinder ( 140 is provided with a driving wheel 110 to rotate the bearing on the upper part to allow the vertical movement and traveling movement by mounting the working beam 80 on the upper portion, the driving wheel 110 around the hydraulic cylinder 140 The guide portion is guided during ascending and descending, and is provided with a guide 130 to withstand the horizontal load during the forward and backward driving.
바람직하게, 상기 슬래브를 이동빔에 올려 이송할 때에는 상기 유압실린더(140)의 헤드측으로 고압을 공급하고, 전후진시에는 유압의 공급을 중단하며, 상기 구동휠(110)을 회전구동시켜 상기 슬래브를 이송하고, 상기 슬래브를 고정빔상에 올려 놓는 경우에는 저압의 릴리프압력이 작용하게 하여 작동된다.Preferably, when transporting the slab to the moving beam to supply the high pressure to the head side of the hydraulic cylinder 140, stops the supply of the hydraulic pressure when moving forward and backward, the drive wheel 110 is rotated to drive the slab In the case of conveying and placing the slab on the fixed beam, a low pressure relief pressure is applied to operate the slab.
이하, 첨부된 도면을 참조로 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 발명에 따른 워킹빔 지지장치를 보여주는 개략도이다.3 is a schematic view showing a working beam support apparatus according to the present invention.
이를 참조하면, 수직의 유압실린더(140) 상부에 베어링 회전하는 구동휠(110)을 구비시키고, 그 상부에 워킹빔(80)이 안착된다.Referring to this, the driving wheel 110 is provided to rotate the bearing on the vertical hydraulic cylinder 140, the working beam 80 is mounted on the upper.
그리고, 승하강시 구동휠(110)부분의 기울어짐이 없고, 전후진 구동시 수평방향 부하를 견딜 수 있도록 유압실린더(140) 주위에 가이드(130)가 부설된다.In addition, there is no inclination of the driving wheel 110 in the ascending and descending, and the guide 130 is installed around the hydraulic cylinder 140 to withstand the horizontal load during the forward and backward driving.
본 발명에 따르면, 상승운동을 할 경우에는 유압실린더(140)의 헤드부로 고압을 공급하여 워킹빔(80)을 들어 올리며, 하강시에는 공급 압력은 그대로 둔 상태에서 자중에 의해 릴리프(relief)되어 워킹빔이 하강되도록 하고, 구동휠(110)의 구동으로 슬래브를 이송시키게 된다.According to the present invention, in the case of the upward movement, the high pressure is supplied to the head of the hydraulic cylinder 140 to lift the working beam 80, and during the lowering, the supply pressure is released by its own weight while being kept intact. The working beam is lowered, and the slab is transferred by the driving of the driving wheel 110.
이상과 같은 구성을 가지는 본 발명의 작용에 대해 설명한다.The operation of the present invention having the above configuration will be described.
워킹빔(80) 하부에 설치하여 슬래브를 이동빔에 올려 이송할 때에는 유압실린더(140)의 헤드측으로 고압을 공급하고, 전후진시에는 유압의 공급을 중단하며, 구동휠(110)을 회전구동시켜 슬래브를 이송하고, 슬래브를 고정빔상에 올려 놓는 경우에는 저압의 릴리프압력이 작용하게 하여 워킹빔(80)이 하강하는데 문제가 없도록 한다.When the slab is installed on the lower portion of the working beam 80 and transferred to the moving beam, high pressure is supplied to the head side of the hydraulic cylinder 140, and when back and forth, the supply of hydraulic pressure is stopped and the driving wheel 110 is rotated. When the slab is transported and the slab is placed on the fixed beam, a low pressure relief pressure is applied to prevent the working beam 80 from descending.
덧붙여, 정비 및 취외가 필요한 경우에는 유압실린더(140)의 헤드측 압력을 탱크(미도시)로 보내어 실린더로드가 실린더튜브안으로 완전히 들어 가게 하여 기준 높이 이하로 내린 후 작업을 하게 된다.In addition, when maintenance and extraction are necessary, the head side pressure of the hydraulic cylinder 140 is sent to a tank (not shown) to allow the cylinder rod to fully enter the cylinder tube, and then work down after the reference height is lowered.
본 발명에 따른 워킹빔 지지장치는 열연 가열로의 워킹빔에만 적용가능한 것이 아니고 고하중, 사이클운동을 하는 개소에는 어느 곳에도 적용 가능함은 물론이다.The working beam supporting apparatus according to the present invention is not only applicable to the working beam of the hot-rolled heating furnace, but also can be applied to any place where high loads and cycle movements are performed.
본 발명에 따르면, 유압식 워킹빔 지지장치를 사용함으로써, 구성이 간단하여 공간에 제약을 받지 않고, 일정 하중이상이 걸리면 즉시 하강되어 구성 부품의 이상을 예방하여, 경제성과 사용상의 효율성이 제고되며, 설비가동 향상에 따른 생산성향상과 조업안정에 따른 품질향상의 효과가 달성될 수 있다.According to the present invention, by using a hydraulic working beam support device, the configuration is simple and is not restricted by space, and if a certain load or more is applied, it immediately descends to prevent abnormalities of components, thereby improving economic efficiency and efficiency in use. Productivity improvement due to improved facility operation and quality improvement due to operational stability can be achieved.
