본 고안은 아파트나 고층건물에 설치하여 화물 및 이삿짐을 승강시키는 곤도라에 관한 것으로, 특히 승강하는 화물의 중량이 규정 용량을 초과하는 경우에나 과부하 발생시 감지장치가 동작하여 곤도라의 운전을 자동적을 중단시키도록 하므로써 사고를 미연에 방지하고 안전운전을 기하도록 한 곤도라의 과부하 방지 장치에 관한 것이다.The present invention relates to a gondola that lifts cargo and moving by installing it in an apartment or a high-rise building, especially when the weight of the lifting cargo exceeds a specified capacity or when an overload occurs, the detection device operates to automatically stop the operation of the gondola. The present invention relates to a gondola overload protection device which prevents accidents and ensures safe driving.
종래의 곤도라 과부하 방지 장치는 과부하 계전기가 과전류를 감지하는 것으로서 도면 제2도에 도시되어 있는것과 같이 적재함(8)에 화물 및 이삿짐을 싣고 모터(4)의 구동에 의해 동력전달이 커플링(3)과 감속기(2)로 전달되어 드럼(1)이 구동함으로써 와이어 로프(10)가 롤러(5,5'),(6,6')와 도르레(9.9')를 통과하여 적재함(8)이 승강될때 조작반함(4')에 내장된 과부하 계진기가 모터(4)에 흐르는 전류를 감지하도록 구성되어 있다.In the conventional gondola overload protection device, the overload relay senses an overcurrent and loads and moves the cargo into the loading box 8 as shown in FIG. 2 and the power transmission is driven by the driving of the motor 4. And the drum 1 is driven so that the wire rope 10 is loaded through the rollers 5, 5 ', 6, 6' and the pulley 9.9 '. It is configured to sense an electric current flowing in the motor 4 by the overload meter built into the control panel 4 'when being elevated.
이러한 종래 곤도라의 작동 상태를 살펴보면 도면 제1도에서와 같이, 곤도라를 아파트나 고층건물의 옥상에 설치하여 조작반함(4')을 운전함에 따라 도면 제2도의 모터(4)가 구동되어 동력이 드럼(1)에 전달되어 회전함으로써 와이어로프(10)가 드럼(1)에 감기거나 풀리면서 화물 및 이삿짐을 실은 적재함(8)이 승강하게 된다.Referring to the operation state of the conventional gondola as shown in FIG. 1, as the gondola is installed on the roof of an apartment or a high-rise building to operate the operation box 4 ', the motor 4 of FIG. As the wire rope 10 is transferred to the drum 1 and rotates, the storage box 8 carrying cargo and moving is lifted while the wire rope 10 is wound or unwound on the drum 1.
이와같이 적재함(8)에 화물 및 이삿짐을 규정 이상의 중량을 싣고 조작반함(4')을 운전하게 되면 모터(4)에 과전류가 흐르게 되고 이 과전류를 조작반함에 내장된 과부하 계전기가 과전류를 감지하여 조작반함의 전원을 차단시켜 곤도라의 운전을 중지시키게 된다.In this way, when the operation box (4 ') is loaded with more than specified weight of cargo and moving in the stacking box (8), overcurrent flows to the motor (4), and the overload relay built in the control panel detects the overcurrent and controls the board. The gondola is stopped by shutting off the power.
그러나 사용자가 곤도라 운전시 작업을 무리하게 하기 위하여 도면 제2도에서 같이 조작반함(4')에 내장된 과부하 계전기의 전류조정 손잡이를 최대로 조정하여 적재함(8)에 규정이상의 중량을 싣고 운전하므로 과부하 계전기가 규정용량 이상의 과전류를 감지 못하게 되어 결국에는 무리한 작업 또는 과부하로 인하여 곤도라에 큰 부하가 발생되어 종종 사고가 발생되는 것이다.However, in order to force the user to operate the gondola, the current adjustment knob of the overload relay built in the operation box 4 'is adjusted to the maximum so as to load the weight more than specified in the loading box 8 as shown in FIG. Overload relays can't detect overcurrents beyond the rated capacity, which in turn leads to heavy loads on the gondola due to excessive work or overload, which often leads to accidents.
따라서 본 고안은 곤도라 운전자가 과부하 계전기를 임의대로 조정함으로써 과부하 계전기의 기능이 상실되어 과부하를 감지 못하는 현상을 해소하기 위한 것으로서 와이어 로프의 장력을 별도의 과부하 감지 장치가 기구적으로 감지하여 규정이상의 화물 및 이삿짐을 싣고 운전시에는 자동적으로 운전을 중지시키게 하는 것을 목적으로 한다.Therefore, the present invention is designed to solve the phenomenon that the gondola driver loses the function of the overload relay by arbitrarily adjusting the overload relay and detects the overload. And aims to automatically stop the operation when driving on the move.
이하에서 이를 첨부 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, this will be described in detail with reference to the accompanying drawings.
도면 제3도와 같이 양쪽의 아암(7,7')에 롤러(11,11')를 고정 취부하여 "A"부의 상세 구성도인 도면 제4도에서 처럼 와이어 로프(10)를 롤러(6)의 안쪽에서 롤러(19)의 바깥쪽으로 통과하게 하여 롤러(11)의 안쪽으로 통과하도록 구성되어 있고 사각파이프(12)를 아암(7)에 고정하고 사각파이프(12)내부에는 장력을 감지하는 강력스프링(17)이 축(14)에 끼워지도록 구성되고 스프링(17)자체의 인장력에 의해 축(14)이 빠지는 것을 방지하기 위해 축(14)에 브라켓트(18)를 용접 취부하여 고정하도록 구성되어 있다. 또한 와이어 로프(10)의 장력이 전달될수 있도록 롤러(19)와 축(14)을 고정시키도록 구성하고, 스프링(17) 자체 인장력을 조정할수 있도록 축(14)의 끝부분에 너트(13)를 끼워서 조정할수 있도록 구성하고 사각파이프(12)에 브라켓트(16)를 취부하여 과부하를 감지하도록 리미트스의치(15)를 고정하도록 구성되어 있다.As shown in FIG. 3, the rollers 11 and 11 'are fixedly mounted to the arms 7 and 7' on both sides, so that the wire rope 10 is rolled as shown in FIG. It is configured to pass from the inside of the roller 19 to the outside of the roller 11 to pass through the inside of the roller 11 and to secure the square pipe 12 to the arm (7) and to sense the tension inside the square pipe (12) The spring 17 is configured to be fitted to the shaft 14 and the bracket 18 is welded and fixed to the shaft 14 to prevent the shaft 14 from being pulled out by the tension force of the spring 17 itself. have. It is also configured to fix the roller 19 and the shaft 14 so that the tension of the wire rope 10 can be transmitted, and the nut 13 at the end of the shaft 14 to adjust the tension force of the spring 17 itself It is configured to be adjusted by inserting the bracket 16 to the square pipe 12 is configured to fix the limit denture 15 to detect the overload.
이상과 같이 구성된 본 고안의 작동상태를 살펴보면, 도면 제4도에서와 같이 와이어 로프(10)가 롤러(6,19,11)를 통과하게 되어 있어 곤도라의 적재함(8)에 규정된 중량을 싣고 운전시에는 사각파이프(12)내부에 있는 강력스프링(17)의 인장력에 의해 롤러(19)에 고정된 축(14)이 밀리지 않으므로 정상적인 운전을 계속할수 있으나 규정이상의 중량을 싣고 운전시에는 와이어 로프(10)에 강력한 발생되어 이 장력에 의해 롤러(19)에 고정된 축(14)에 장력이 전달되어 결국에는 축(14)에 고정된 브라켓트(18)가 스프링(17)을 압축시키게 되어 축(14)의 끝부분이 리미트스위치(15)를 동작시키게 되고, 이 리미트스위치(15)의 동작에 의해 조작반함(4')의 전원을 차단시킴으로써 과부하 발생시 곤도라의 운전을 중지시킬수 있게 된다.Looking at the operating state of the present invention configured as described above, as shown in Figure 4 the wire rope 10 is to pass through the rollers (6, 19, 11) to carry the weight prescribed in the loading box (8) of the gondola In operation, the shaft 14 fixed to the roller 19 is not pushed by the tension force of the strong spring 17 in the square pipe 12, so that normal operation can be continued. The force is transmitted to the shaft 14 fixed to the roller 19 by the strong force generated in this 10, and eventually the bracket 18 fixed to the shaft 14 compresses the spring 17 so that the shaft 17 The end portion of (14) operates the limit switch 15, and the operation of the limit switch 15 cuts off the power supply of the operation box 4 'so that the operation of the gondola can be stopped when an overload occurs.
이상과 같이 구성되고 작용되는 본 고안의 롤러의 추가 설치와 이 롤러에 지나는 와이어로프의 장력을 감지하는 감지장치에 의해 과부하시의 곤도라의 운전을 정지시킴으로써 과부하에 의한 곤도라 적재함의 추락등의 안전사고를 일소시킴으로써 아파트 곤도라에 대한 고신뢰성을 보장하는 매우 유용한 고안인 것이다.Safety accidents such as falling of the gondola loading box due to overloading by stopping the operation of the gondola in the event of overload by the additional installation of the roller of the present invention constructed and operated as described above and a sensing device for sensing the tension of the wire rope passing through the roller. It is a very useful design that guarantees high reliability for the apartment gondola by sweeping the.
