Abstract

PURPOSE: An elevating platform is provided to accurately and safely check a working state and a processing state in a high position by using a lift moving a worker vertically and to enhance the efficiency of work by reducing the operating time of a working machine. CONSTITUTION: An elevating platform comprises: a cabin(10) supported by a lift frame(20); a lifting device moving the cabin up and down; and a controller controlling the cabin and the lift frame. The lifting device moves the cabin up and down with a chain(33) connected to an oil hydraulic cylinder(31). Herein, the oil hydraulic cylinder is fixed to the lift frame. The chain is crossly wound on a movable roller(32) and a fixed roller(34) so that one end of the chain is fixed to the lift frame and the other end is fixed to the rear end of the cabin. Since the chain is crossly wound on each roller, the cabin is vertically moved with the half of a cylinder force.

Description

엘리베이팅 플레트 포옴{elevating patform}Elevating patform

본 발명은 작업자의 작업영역을 기계가공 위치에 맞도록 임의로 이동시켜 작업의 편의성과 작업 효율을 크게 증대시킬 수 있는 엘리베이팅 풀래트 포옴에 관한 것이다.The present invention relates to an elevator full-rate foam that can move the work area of the worker arbitrarily to match the machining position to greatly increase the convenience and work efficiency of the work.

일반적으로 공작기계에서 작업을 하는 작업자들 대부분은 기계가 설치되는 지면에 서 있는 상태에서 작업중에 있는 기계의 작업상태를 확인하고 있다.In general, most of the workers working on machine tools check the working status of the machine in operation while standing on the ground where the machine is installed.

그렇지만 대형 공작기계의 경우 작업자 보다 기계가 높은 위치에 위치하여 작업자는 정상적인 위치에서는 작업 상황을 정확히 확인하는데 어려움이 있다.However, in the case of large machine tools, the machine is located at a higher position than the worker, and thus, the worker has difficulty in accurately checking the working situation at the normal position.

더욱이 기계가 움직이고 있는 상태에서 작업상태를 확인하는 것은 작업자에게는 위험 천만하고, 칩 등의 작업 이물질로부터 작업자를 보호할 수도 없어 안전사고의 염려가 있는 등의 문제점을 안고 있다.Furthermore, checking the working state while the machine is in motion is dangerous to the worker, and there is a problem that there is a risk of a safety accident because the worker cannot be protected from foreign objects such as chips.

상기한 종래의 문제점은 공작기계의 크기에 관계없이 작업자의 위치가 모두 동일하다는데서 비롯되었던 것이다.The above-mentioned conventional problem arises from the fact that the positions of the workers are all the same regardless of the size of the machine tool.

본 발명은 상기한 종래의 문제점을 해소하기 위해서, 작업자의 위치를 상,하로 이동시킬 수 있도록 된 리프트를 이용하여 높은 위치에서 작업하고 있는 기계의 작업상태 및 공작물의 가공 상태 등도 작업자가 정확하고 안전하게 확인할 수 있게함과 아울러 기계 조작시간도 줄여 작업 효율을 크게 증대시킬 수 있는 작업 환경을 조성함에 있는 것이다.The present invention, in order to solve the above-mentioned problems, the operator's working state of the machine working at a high position and the processing state of the workpiece using the lift that can move the position of the operator up and down, and the like, the operator can accurately and safely In addition to being able to check and reduce the operating time of the machine to create a work environment that can greatly increase the work efficiency.

이하, 본 발명을 첨부된 예시 도면에 의거하여 구성 및 작용 효과 등을 보다 상세하게 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in more detail the configuration and operation effects and the like.

도 1은 본 발명에 따른 엘리베이팅 플래트 포옴 전면부의 구성을 나타낸 예시도이고, 도 2와 도 3은 평면과 측면부의 구성을 도시하고 있는 예시도이다.1 is an exemplary view showing a configuration of an elevator platform foam front portion according to the present invention, Figures 2 and 3 are exemplary views showing the configuration of the plane and the side portion.

이에 도시된 바와 같이 리프트 프레임(20)과, 작업자를 보호할 수 있도록 일정한 크기로 구획되는 캐빈(10)과, 상기 캐빈(10)을 임의의 높이로 이동시키는 승강장치(30) 및 이를 제어하는 콘트롤러(40)로 구성되어 있다.As shown therein, the lift frame 20, the cabin 10 partitioned to a certain size so as to protect the operator, and the lifting device 30 for moving the cabin 10 to a certain height and controlling it The controller 40 is comprised.

캐빈(10)은 프레임(20)의 일측에 설치되어 작업자를 임의의 높이로 상승, 하강시키는 리프트의 기능을 가지는 것으로, 상기 캐빈(10)은 리프트 프레임(20)에 형성되는 가이드(22)를 따라 이동하도록 되어 있다.Cabin 10 is installed on one side of the frame 20 has a function of the lift to raise and lower the worker to any height, the cabin 10 is a guide 22 formed in the lift frame 20 To move along.

캐빈(10)은 한쪽면은 오픈되고 나머지 3면은 칸막이로 차폐되는 구성으로 되어 상기 공간내에서는 작업자의 안전을 보장받을 수 있도록 되고, 한쪽면에는 작업자가 출입하는 도어(12)가 부설되어 있다.The cabin 10 has one side open and the other three sides are shielded by partitions so that the safety of the operator can be guaranteed in the space, and the door 12 is provided on one side of the cabin 10. .

승강장치(30)는 리프트 프레임(20)에 일측단이 고정되는 유압실린더(31)와, 캐빈(10)을 상,하부측으로 끌어올리고 내리도록 된 체인(33)과, 상기 체인(33)을 안내하는 가동형 롤러(32)와 고정롤러(34)로 구성되어 있다.Lifting device 30 is a hydraulic cylinder 31, one end of which is fixed to the lift frame 20, the chain 33 to raise and lower the cabin 10 to the upper and lower sides, and the chain 33 It consists of the movable roller 32 and the fixed roller 34 which guide.

가동형 롤러(33)는 유압실린더(31)의 끝단에 고정되고, 고정롤러(34)는 리프트 프레임(20)의 상부측에 고정되고, 체인(33)은 한쪽 선단이 리프트 프레임(20)에 고정되고 타측은 각각의 롤러(32,34)에 권취된 후 캐빈(10)의 후단부에 고정되고 있다.The movable roller 33 is fixed to the end of the hydraulic cylinder 31, the fixed roller 34 is fixed to the upper side of the lift frame 20, the chain 33 is one end of the chain to the lift frame 20 The other side is fixed and wound on the rear end of the cabin 10 after being wound on the respective rollers 32 and 34.

콘트롤러(40)는 캐빈(10) 내부에 설치되는 제어판(OPERATOR BOX)과 플렉시블 닥트(FLEXIBLE DUCT) 및 터미널 박스(TERMINAL BOX)를 포함하는 구성으로 되어 있다.The controller 40 is configured to include a control panel (OPERATOR BOX) installed in the cabin 10, a flexible duct (FLEXIBLE DUCT) and a terminal box (TERMINAL BOX).

이와 같이 구성된 본 발명의 작동 관계를 설명하면 다음과 같다.Referring to the operating relationship of the present invention configured as described above is as follows.

작업자가 캐빈(10)에 탑승한 후 출입구(20)를 닫은 다음 콘트롤러(40)를 조작하여 승강장치(30)를 동작시키면 유압실린더(31)와 연결된 체인(33)을 잡아당김에 따라 캐빈(10)은 상부측으로 이동하게 된다.When the operator boards the cabin 10, closes the entrance 20, and then operates the controller 40 to operate the lifting device 30, pulling the chain 33 connected to the hydraulic cylinder 31 and pulling the cabin ( 10) is moved to the upper side.

즉 캐빈(10)이 내려져 있는 상태에서는 유압실린더(31)의 피스톤이 빠져 나와 있는 상태이므로 상기 실린더의 "P" 포트(입구)에 유압유가 유입되면 실린더의 피스톤이 내려오게 되고, 피스톤이 내려오면 이와 연결된 체인을 잡아당기게 되므로 캐빈은 체인에 의해 상부측으로 올라가고, 반대로 "T"포트(출구)로 유압유가 빠지면 실린더의 피스톤이 올라감에 따라 체인을 잡아당기는 인장력이 느슨해짐에 따라 캐빈은 하부측으로 이동하게 된다.In other words, when the cabin 10 is lowered, the piston of the hydraulic cylinder 31 is pulled out, so when hydraulic oil flows into the "P" port (inlet) of the cylinder, the piston of the cylinder is lowered, and the piston is lowered. As the chain is pulled up, the cabin is moved upwards by the chain. On the contrary, when the hydraulic oil is released through the "T" port (outlet), the cabin moves downward as the tension of the chain is loosened as the piston of the cylinder rises. Done.

이때 캐빈(10)을 끌어올리는 체인(33)은 실린더(31)와 리프트 프레이(20)에 각각 고정되는 각각의 롤러(32,34)에 서로 엇갈리게 권취되고 있어 전체 이동 스트로크의 1/2이 되는 실린더 힘만으로 캐빈은 상,하로 이동할 수 있는 것이다.At this time, the chain 33 that pulls up the cabin 10 is wound around each other by rollers 32 and 34 fixed to the cylinder 31 and the lift frame 20, respectively, to be 1/2 of the entire moving stroke. The cabin can move up and down only by the cylinder force.

이처럼 본 발명은 작업자를 기계가 작업하는 위치의 높이 만큼 상,하로 이동시켜주기 때문에 기계작업을 보다 더 가까운 곳에서 정확하고 안전하게 관찰 할 수있고, 작업도 편리하게 이루어질 수 있는 것으로, 특히 보링머신과 같은 대형 공작기계에 유용하게 적용될 수 있는 것이다.As described above, the present invention moves the worker up and down by the height of the machine working position, so that the machine work can be observed accurately and safely at a closer position, and the work can be conveniently performed. It can be usefully applied to the same large machine tools.

이상에서와 같이 본 발명에서와 같은 대형 공작기계에 설치하게 되면높은 위치에서 작업하고 있는 기계의 작업상태 및 공작물의 가공 상태를 작업자가 가까이서 정확하고 안전하게 확인 할 수 있는 이점이 있게 된다.When installed in a large machine tool as in the present invention as described above there is an advantage that the operator can check the working state of the machine working at a high position and the machining state of the workpiece close and accurate and safe.

또한, 작업자는 기계의 작업위치에서 작업상태를 관찰하고 파악할 수 있기 때문에 작업성이 향상됨은 물론 기계 조작에 필요한 시간도 줄일 수 있어 작업 효율 또한 크게 증대를 도모할 수 있는 것이다.In addition, the operator can observe the work state at the working position of the machine and can improve the workability as well as reduce the time required for the operation of the machine, thereby greatly increasing the work efficiency.

그리고 작업자는 안전한 캐빈를 이용하여 작업진행 정도를 살필 수 있어 안전사고를 사전 예방할 수 있는 등의 작용 효과를 가지는데 그 특징이 있다.In addition, the worker can check the progress of the work using a safe cabin has the characteristics of having an effect such as to prevent the safety accident in advance.
