Description

하수관로용 원격커팅장치의 커팅암 구동구조{cutting arm operational structure of remote controlled cutting device for sewer}Cutting arm operational structure of remote controlled cutting device for sewer

본 발명은 하수관로용 원격커팅장치의 커팅암 구동구조에 관한것으로, 더욱상세하게는, 하수관로 내부에서 원격조정에 의해 작동되어 하수관로 내부의 돌출물을 커팅하는 원격커팅장치에 있어 커팅수단의 커팅암 구동이 복수의 워엄 및 헬리컬기어로 되는 구동부에 의해 안정적으로 지지된 상태에서 보다 확실하게 회전력이 전달될 수 있게 함과 동시에 주축 워엄기어 내부에는 관통공을 형성하여 커팅부의 구동을 위한 각종 케이블이 관통 연결되게 하여 케이블이 외부로 드러나지 않게 되므로 케이블이 꼬이게 되는 작업 방해요인의 해소 및 원격커팅장치의 외관을 미려하게 한 것이다.The present invention relates to a cutting arm driving structure of the remote cutting device for sewage pipe, more specifically, the cutting arm driving of the cutting means in the remote cutting device that is operated by remote control in the sewage pipe to cut the protrusions inside the sewage pipe. In addition, it is possible to more reliably transmit the rotational force in a stably supported state by a drive unit including a plurality of worms and helical gears, and a through hole is formed in the main shaft worm gear to connect various cables for driving the cutting unit. Therefore, the cable is not exposed to the outside, thereby eliminating the work-twisting factor that causes the cable to twist and beautifully appearance of the remote cutting device.

일반적으로 하수관로 내부의 각종 돌출물의 커팅을 위해 하수관로용 원격커팅장치가 사용되고 있는 것인바, 이들 사용되고 있는 원격커팅장치는, 그 대부분의 본체 프레임 일측에 커팅암과 구동모터가 직결방식에 의해 연결되어 작동되도록 하고 있는 것이어서, 선단에 커팅휠이 방향전환 가능하게 설치되는 작동암을 구동모터가 구동시키는 과정에서 구동모터에 부하가 걸려 작동암의 원할한 회전동작이 이루어질 수 없게 될 뿐만 아니라, 작동암의 작동이 아예 멈춰버리게 되는 경우가 발생하는 등 커팅장치의 전체의 수명이 단축되게 되는 문제가 있는 것이었다.In general, the remote cutting device for the sewage pipe is used to cut various protrusions inside the sewage pipe, and these used remote cutting devices operate by directly connecting the cutting arm and the driving motor to one side of the main body frame. Since the driving motor loads the driving motor in the process of driving the operating arm in which the cutting wheel is reversibly installed at the distal end, a smooth rotational motion of the operating arm is not possible, There was a problem that the entire life of the cutting device is shortened, such as when the operation is stopped at all.

또는 상기와 같이 커팅암을 구동모터에 직결되게 연결하지 않고 구동모터와 커팅암을 기어구동에 의해 연결되도록 하는 경우도 있으나, 이는 단수의 워엄기어만을 이용하여 구동모터의 회전력이 주축기어에 전달되도록 하며 커팅암이 임의 회전되도록 한 것으로, 이 역시 구동모터의 구동력이 정확하게 주축기어에 전달되지 않을 뿐만 아니라, 커팅암과 연결된 주축기어와 워엄 사이에 유격이 발생하여 회전력의 손실이 발생하게 되므로 커팅암의 정확한 작동이 불가능하게 되는 문제와 함께 구동부가 정교한 조립상태를 기대할 수 없게 되어 역시 장기간 작동하는 과정에서 쉽게 고장을 일으키게 되므로 원격커팅장치의 전체적인 사용수명이 단축될 수 밖에 없는 등의 문제가 있는 것이었다.Alternatively, as described above, the driving motor and the cutting arm may be connected to each other by gear driving without directly connecting the cutting arm to the driving motor. However, the driving force may be transmitted to the main shaft gear by using only a single worm gear. In addition, the cutting arm is rotated arbitrarily, and this also causes the driving force of the drive motor not to be accurately transmitted to the spindle gear, and the cutting arm is lost due to the play between the spindle gear and the worm that is connected to the cutting arm. In addition to the problem that the precise operation of the drive unit can not expect the precise assembly state, too, it is easy to cause a failure in the process of long-term operation, there is a problem such that the overall service life of the remote cutting device can only be shortened. .

따라서 본 발명의 목적은 상기와 같이 커팅수단의 커팅암이 구동모터와 직결되거나 불완전한 상태로 기어 구동에 의해 연결되도록 한 종래의 하수관로용 원격커팅장치의 커팅암 구동구조가 지닌 제반 문제점을 해결하기 위하여, 커팅암이 구동모터에 의해 360°회전 가능하게 하되, 커팅암의 연결부는 각각 복수의 헬리컬기어 및 워엄에 의해 회전력을 전달받는 중공의 주축 워엄기어로 되는 구동부에 연결되게 하여, 커팅암이 보다 정교하고 안정적으로 구동모터와 조립 연결된 상태에서 회전작동되게 함으로써 커팅장치에 의한 보다 효과적인 커팅작업이 이루어지게 될 뿐만 아니라 커팅부의 구동을 위한 각종 케이블을 주축 워엄기어 내부로 삽입 관통되게 하는 것에 의해 커팅암의 작동시 케이블의 꼬임을 막고 케이블의 노출을 피할 수 있게 되어 케이블에 의한 원격커팅장치의 작동이 방해받지 않도록 한 하수관로용 원격커팅장치의 커팅암 구동구조를 제공함에 있다.Accordingly, an object of the present invention is to solve the problems of the conventional cutting arm driving structure of the remote cutting device for the sewer pipe that the cutting arm of the cutting means is connected to the driving motor directly or incompletely by the gear drive. The cutting arm is rotatable 360 ° by the drive motor, but the cutting arm connection part is connected to the driving part of the hollow main shaft worm gear that receives the rotational force by a plurality of helical gears and worms, respectively. The cutting arm is not only made more efficient by the cutting device by rotating in precisely and stably assembled with the driving motor, but also by inserting various cables for driving the cutting part into the spindle worm gear. Prevents the cable from being twisted and avoids cable exposure during operation So that the remote operation of the cutting apparatus according to the table is not disturbed by the cutting arm drive structure of the remote device for cutting hasugwanro to provide.

상기한 주축(3)은 일정길이를 갖는 봉체 형태로 되어 그 내부에는 각종 케이블이 관통될 수 있도록 중공부(32)를 형성하고 있으며, 상기 구동기어(2)의 워엄(21)(21)에 대응하는 외면에는 워엄기어(31)가 형성되어 상기 워엄(21)(21)과 치합되도록 설치된다.The main shaft 3 is in the form of a rod having a predetermined length and has a hollow portion 32 formed therein so that various cables can pass therethrough, and the worms 21 and 21 of the drive gear 2 are formed. A worm gear 31 is formed on the corresponding outer surface so as to be engaged with the worms 21 and 21.

이때 상기 주축(3)의 회전축선은 구동기어(2)의 회전축선과 직각으로 교차됨과 동시에 상기 작동기어(1)의 회전축선 위쪽으로 나란한 회전축선을 갖도록 설치된다.At this time, the axis of rotation of the main shaft (3) is installed so as to cross at a right angle with the axis of rotation of the drive gear (2) and at the same time above the axis of rotation of the operating gear (1).

It is installed to be coupled to (12).

상기와 같은 구성으로 되는 본 발명에 의한 하수관로용 원격커팅장치의 커팅암 구동구조의 실시작동상태에 대해 설명한다.The operation of the cutting arm drive structure of the remote cutting device for sewage pipes according to the present invention having the configuration as described above will be described.

내부에 구동부(A)가 수밀상태로 설치된 본체(5)가 프레임(6)에 설치되게 한 원격커팅장치(a)의 커팅암(4)을 회전 구동시키려 하는 경우, 별도의 원격조정수단(도시생략)을 이용하여 본체(5) 일측에 모터케이스(72)에 의해 수밀상태로 부착 설치되는 구동모터(7)를 작동시키게 되면, 그 회전력은 구동축(71)을 거쳐 작동기어(1)에 전달되어 작동기어(1)가 회전하게 된다.In order to drive rotation of the cutting arm 4 of the remote cutting device (a) in which the main body 5 installed in the watertight state with the driving unit A sealed therein is provided with a separate remote control means (not shown). When the driving motor 7 is installed in the watertight state by the motor case 72 on one side of the main body 5, the rotational force is transmitted to the operating gear 1 via the driving shaft 71. The operating gear 1 is rotated.

이렇게 작동기어(1)가 회전하게 되며, 그 회전력은 작동기어(1) 둘레면에 형성된 헬리컬기어부(11) 양측으로 헬리컬워엄(22)(22)이 각각 밀접된 상태로 설치된 구동기어(2)(2)에 전달되어 양 구동기어(2)(2)를 동일 회전수로 회전시키게 된다.The operating gear 1 is rotated as described above, and the rotational force is the driving gear 2 provided with the helical worms 22 and 22 close to both sides of the helical gear part 11 formed on the circumferential surface of the operating gear 1, respectively. 2) to rotate both drive gears (2) (2) at the same speed.

이렇게 구동기어(2)(2)에 전달된 회전력은 다시 구동기어(2)(2) 상부 둘레면에 형성된 워엄(21)(21)에 의해 워엄(21)(21) 사이에 치합된 주축의 워엄기어(31)가 회전되게 됨에 따라 주축(3)이 회전하게 되고 이 주축(3)의 회전력은 주축(3)의 결합구(33) 및 다수의 고정볼트에 의해 부착 연결되는 커팅암(4)의 연결부(41)에 그대로 전달되게 되어 결과적으로 커팅암(4)이 구동모터(7)의 정,역회전에 따라 원하는 방향으로 정,역회전되게 된다.The rotational force transmitted to the drive gears (2) and (2) in this way is driven by the worms (21) and (21) formed on the upper circumferential surface of the drive gears (2) and (2). As the worm gear 31 is rotated, the main shaft 3 rotates, and the rotational force of the main shaft 3 is attached to the cutting arm 4 attached by the coupling holes 33 and the plurality of fixing bolts of the main shaft 3. As it is transmitted to the connection portion 41 of the) as a result, the cutting arm 4 is rotated forward and reverse in the desired direction according to the forward, reverse rotation of the drive motor (7).

상기 구성에 있어서, 작동기어(1)와 구동기어(2)를 도 5에 도시하고 있는 바와 같이 작동기어(1) 둘레면에 헬리컬기어부(11) 대신에 워엄(11-1)을 형성하고 이와 치합되는 구동기어(2)(2) 하부에는 헬리컬워엄(22)(22) 대신에 웜엄기어(22-1)(22-1)를 형성하여 구동모터(7)의 회전력이 워엄(11-1)과 워엄기어(22-1)(22-1)를 거쳐 주축(3)에 전달되게 할 수도 있는 것으로, 실질적으로 구동모터(7)에 의한 회전력이 작동기어(1)와 구동기어(2)(2)를 거쳐 구동기어(2)(2) 상부의 워엄(21)(21)에 전달되게 하여 이 워엄(21)(21)에 치합된 워엄기어(31)를 통해 주축(3)에 그대로 전달되게 하는 것에 의해 주축(3)이 회전 구동되도록 하는 구성이면, 상기 작동기어(1)와 양 구동기어(2)(2)간의 기어결합 형태를 특정기어 형태로 제한하는 것은 아니다.In the above configuration, as shown in Fig. 5, the actuating gear 1 and the actuating gear 2 are formed on the circumferential surface of the actuating gear 1 to form a worm 11-1 instead of the helical gear 11. The worm gears 22-1 and 22-1 are formed in the lower portion of the drive gears 2 and 2 that are engaged with the worm wheels 22 and 22 so that the rotational force of the drive motor 7 is increased. 1) and the worm gear 22-1, 22-1 may be transmitted to the main shaft (3), the rotational force by the drive motor (7) is substantially the operating gear (1) and the drive gear (2) (2) to the worm (21) (21) on the top of the drive gear (2) (2) to the main shaft (3) through the worm gear (31) fitted to the worm (21) (21) If the main shaft 3 is rotated by being transmitted as it is, the form of gear engagement between the operating gear 1 and both drive gears 2 and 2 is not limited to the specific gear shape.

이때 본 발명에 의한 커팅암 구동구조를 이루는 구동부(A)는, 구동모터(7)에 의해 회전력을 최초 전달받는 작동기어(1)와 구동모터(7)에 의한 회전력이 최종적으로 커팅암(4)으로 전달되도록 하는 주축(3)을 모두 복수의 구동기어(2)(2)에 의해 그 양측에서 지지되게 하는 형태로 회전력의 전달이 이루어지도록 하고 있으므로 회전력 전달이 확실할 뿐만 아니라 보다 안정적인 설치상태에서 작동되게 된다.At this time, the driving unit (A) constituting the cutting arm drive structure according to the present invention, the rotational force by the operating gear (1) and the drive motor (7) which is initially transmitted to the rotational force by the drive motor 7 finally the cutting arm (4) The rotational force is transmitted in a form in which the main shafts 3 to be transmitted to the main shaft 3 are supported on both sides by the plurality of drive gears 2 and 2 so that the rotational force transmission is assured and a more stable installation state. It will work on.

이상에서와 같이 본 발명은 비록 상기의 실시예에 한하여 설명하였지만 반드시 여기에만 한정되는 것은 아니며 본 발명의 범주와 사상을 벗어나지 않는 범위 내에서 다양한 변형실시가 가능함은 물론이다.As described above, although the present invention has been described with reference to the above embodiments, it is not necessarily limited thereto, and various modifications may be made without departing from the scope and spirit of the present invention.

이상의 설명에서 분명히 알 수 있듯이 본 발명의 하수관로용 원격커팅장치의 커팅암 구동구조에 의하면, 본체 내부에 수밀상태로 설치되는 구동부의 구성이, 구동모터와 연결되는 작동기어 및 작동암과 연결되는 주축을 그 양측에서 구동기어에 의해 회전가능하게 지지되게 함으로써 주축이 보다 확실하고 안정적으로 지지된 상태에서 회전구동되게 되므로 커팅수단에 의한 커팅과정에서 커팅암에 부하가 걸리더라도 주축과 구동기어간에 유격이 발생되지 않게 되므로 항상 구동모터의 회전구동력이 확실하고 정확하게 커팅암에 전달되어 커팅암의 작동효율을 높일 수 있을 뿐만 아니라, 주축 내부를 중공부로 형성하여 각종 케이블이 관통될 수 있도록 하는 것에 의해 케이블의 꼬임이나 케이블 노출로 인한 커팅장치 전체의 미감저하를 막을 수 있게 되는 등의 유용한 효과를 제공한다.As apparent from the above description, according to the cutting arm driving structure of the remote cutting device for sewage pipe according to the present invention, the configuration of the driving unit installed in the watertight state inside the main body is connected to the driving gear and the operating arm connected to the driving motor. The shaft is rotatably supported by the drive gear on both sides thereof, so that the spindle is rotated in a state where the spindle is more reliably and stably supported. Therefore, even if a load is applied to the cutting arm during cutting by the cutting means, there is a play between the spindle and the drive gear. Since the rotational driving force of the driving motor is always transmitted to the cutting arm reliably and accurately, it can not only increase the operating efficiency of the cutting arm, but also form the hollow part in the main shaft so that various cables can be penetrated. This can prevent the overall deterioration of the cutting device due to twisting or cable exposure. It provides a useful effect, such as that.
