콘 크러셔의 마모도 감시장치{CONE CRUSHER WITH WEAR MONITORING DEVICE}CONE CRUSHER WITH WEAR MONITORING DEVICE}

본 발명은 콘 크러셔(Cone Crusher)의 마모부품의 마모상태를 감시하는 장치에 관한 것이며, 더욱 상세하게는 마모부품인 콘 크러셔의 맨틀(Mantle)과 콘 케이브(Conecave)의 마모도를 단계별로 감시하는 콘 크러셔의 마모도 감시장치에 관한 것이다.The present invention relates to a device for monitoring the wear state of the wear parts of the cone crusher (Cone Crusher), and more specifically to the step of monitoring the wear of the mantle and the cone of the cone crusher of the wear parts The wear of the cone crusher also relates to a monitoring device.

일반적으로 콘크러셔는 죠 크러셔 등에서 1차 파쇄된 골재를 더 작은 크기로 분쇄시키는데 사용하고 있으며, 통상적인 콘 크러셔는 도 1에 도시된 바와 같이, 원통형상의 메인 프레임(1)과, 그 메인 프레임(1)의 내부에서 편심 회전운동을 하는 회전축(2)과, 그 회전축(2)의 상단에 결합된 원추형의 맨틀 코어(3) 및 맨틀(4)과, 그 메인 프레임의 상부에 안착 설치되는 탑 프레임(5)과, 탑 프레임(5)에 나사결합되어 맨틀(4)과 적정거리 이격된 콘 케이브(6)가 설치된 탑셀(7)로 대별된다. 그 외에도, 탑 프레임(5)과 메인 프레임(1) 사이에는 수직부하와 진동을 흡수하는 릴리즈 스프링(8)이 설치되어 있고 또한 메인 프레임(1)의 일측에는 수직 회전축(2)에 구동력을 전달하기 위한 베벨 기어 세트와 수평 구동축(9)과 별도의 동력원으로부터 구동력을 전달받는 풀리(10)로 구성된다. In general, the cone crusher is used to crush the primary crushed aggregate to a smaller size in the jaw crusher, and the conventional cone crusher, as shown in Figure 1, the cylindrical main frame (1), and the main frame ( 1) a rotary shaft 2 for eccentric rotation in the interior, a conical mantle core 3 and a mantle 4 coupled to the upper end of the rotary shaft 2, and a tower mounted on the upper part of the main frame. The top shell 7 is roughly divided into the frame 5 and the top frame 5, and the cone cage 6 spaced apart from the mantle 4 by an appropriate distance is provided. In addition, a release spring 8 for absorbing vertical loads and vibrations is installed between the top frame 5 and the main frame 1, and one side of the main frame 1 transmits a driving force to the vertical rotation shaft 2. Bevel gear set and a horizontal drive shaft (9) and a pulley (10) receiving the driving force from a separate power source.

이러한 구조를 갖는 종래의 콘 크러셔는 통상적으로 골재가 호퍼(11)를 통해 파쇄실(A)로 투입되면, 회전축(2)의 편심회전에 따라 맨틀(4)과 콘 케이브(6) 간극이 가변되고, 골재가 그 간극 변화에 의해 더욱 분쇄되어 파쇄실의 하측(B)으로 낙하 배출되어 분급기에서 분류된 후에 컨베이어 벨트 등에 의해 다음 공정으로 이송된다.In the conventional cone crusher having such a structure, when the aggregate is introduced into the crushing chamber A through the hopper 11, the gap between the mantle 4 and the cone cave 6 is variable according to the eccentric rotation of the rotating shaft 2. The aggregate is further pulverized by the gap change, dropped into the lower side B of the crushing chamber, sorted by a classifier, and then transferred to the next step by a conveyor belt or the like.

그러나 콘 크러셔는 운전가동시간이 경과함에 따라서 맨틀(4)과 콘 케이브(6)등과 같은 마모부품이 점점 마모되어가기 때문에 적절한 시기에 마모부품을 교환해주어야 한다. 그러나 마모부품을 교환하는 일은 통상 많은 작업시간과 상당한 비용이 소요되고 있으며, 또한 적절한 교환시점을 놓치면 탑 프레임(5)이나 맨틀 코어(3)와 같은 설비본체의 파손을 가져올 수 있다. 그리고 고가인 마모 부품을 최대한 허용한도까지 사용하기 위해서나 설비를 안전하게 보호하기 위해서는 그 적절한 교환시점을 파악하는 것은 매우 중요하다.However, the cone crusher needs to be replaced at an appropriate time because wear parts such as the mantle 4 and the cone cave 6 are gradually worn out as the operation time increases. However, replacing worn parts usually takes a lot of work time and considerable costs, and missing the proper time of replacement can result in damage to the installation body, such as top frame 5 or mantle core 3. In addition, it is very important to know the time of proper replacement of expensive wear parts to the maximum allowable limit or to protect the equipment safely.

미국특허 6,129,297에는 콘 크러셔 마모부품의 마모진행을 감시하는 방법을 개시하고 있다. 이 발명에 의하면, 콘 크러셔의 마모부품의 이면(裏面)에 마모가 허용되는 최대 깊이에 우묵한 구멍(Reccess)을 형성하고, 이 우묵한 구멍에 색 조성물(Color Composition) 등의 재료로 채운다. 마모 부품의 침식이 이 우묵한 구멍까지 진행하면 색 조성물이 콘 크러셔의 마모부품의 표면에 퍼지고, 이것에 의해 운전자가 마모상태를 감시할 수 있게 한 것이다. 그러나 이 방법은 콘 크러셔의 동작시에는 정보를 얻을 수 없고, 검사를 위해서는 콘 크러셔를 정지시켜야 하기 때문에 생산능력이 저하되고, 또한 운전자가 콘 크러셔에 가까이 접근하여 상시 육안 으로 감시해야 하기 때문에 운전자의 안전성에도 위험이 따른다.US Pat. No. 6,129,297 discloses a method for monitoring the wear progress of a cone crusher wear part. According to this invention, recesses are formed in the back surface of the wear part of the cone crusher at the maximum depth to which wear is allowed, and the recesses are filled with a material such as a color composition. As the erosion of the wear part progresses to this hollow hole, the color composition spreads on the surface of the wear part of the cone crusher, thereby allowing the operator to monitor the wear state. However, this method cannot obtain information during the operation of the cone crusher, and because the cone crusher must be stopped for inspection, the production capacity is reduced, and the driver must approach the cone crusher and monitor it visually at all times. Safety also poses a risk.

본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위한 것으로, 콘 크러셔를 정지시키지 않고 운전중에도 원격에서 온라인 상으로 마모부품이 일정한 마모도에 이르면 경보나 경고신호를 발하여 운전자가 적절한 대처를 할 수 있는 콘 크러셔 마모감시 장치를 제공하는데 그 목적이 있다.The present invention is to solve the problems of the prior art as described above, when the wear parts reach a certain degree of wear from remote to online even during operation without stopping the cone crusher can alert the driver or the appropriate response Its purpose is to provide a cone crusher wear monitoring device.

상기와 같은 목적을 달성하기 위해, 본 발명은, 콘 크러셔의 마모부품인 콘 케이브와 맨틀의 마모면 이면에 마모도를 검지하는 센서를 매립하여, 마모가 진행되어 소정의 마모허용한도에 도달하면 매립한 센서 끝 부분이 단계적으로 파열되어 전기적인 단락신호나 또는 특정 가스를 분출하게 하고 분출된 특정가스를 검출하여 그 전기적인 신호를 온라인상으로 운전실에 제공하여 경보나 경고수단을 동작시켜 운전자가 조치를 할 수 있게 한 것을 특징으로 한다.In order to achieve the above object, the present invention, by embedding a sensor for detecting the wear level on the back surface of the wear surface of the cone cave and the mantle of the wear parts of the cone crusher, when the wear progresses to reach a predetermined wear tolerance The end of a sensor is ruptured in stages, causing an electrical short signal or a specific gas to be ejected, detecting the ejected specific gas, and providing the electrical signal to the cab online to activate an alarm or warning means. Characterized in that it can be.

온라인 마모도 신호에 근거하여 운전자는 상시 마모부픔의 상태를 원격으로 파악할 수 있어, 설비가 파손되기 전에 계획적으로 마모부품을 교환할 수 있어 설비운전의 효율성이 향상되고. 더구나 이 마모도 신호에 근거하여 고가인 마모부품을 최대한 사용할 수 있어서 원가절감 등의 효과가 있다.Based on the online wear level signal, the operator can remotely identify the state of wear and tear at any time, and can replace the wear parts intentionally before the equipment is damaged, improving the efficiency of the equipment operation. In addition, expensive wear parts can be used as much as possible based on the wear signal, thereby reducing costs.
