It relates to a wheel device.

지하에 매설된 콘크리트 상·하수관의 경우, 노화나 지반의 침하로 인해 관로 상의 연결부위 등에 크랙이 발생 되고, 소정의 크랙이 구멍으로 전이되면서 생활용 상·하수나 산업용 상·하수의 공급 또는 배출시 누수를 일으키게 된다. 이러한 문제점을 해결하기 위한 것으로, 상·하수관 속으로 투입하여 크랙과 같은 흠 부위를 점착성 미가황 고무시트로 보수하는 무인보수기가 널리 이용되고 있다.In the case of concrete water and sewage pipes buried underground, cracks occur in the joints on the pipeline due to aging or subsidence of the ground, and when predetermined cracks are transferred to holes, the supply or discharge of domestic water and sewage, industrial water and sewage It will leak. In order to solve such a problem, an unmanned water dispenser that is used to put into a water and sewage pipe to repair a cracked portion such as a crack with an adhesive unvulcanized rubber sheet is widely used.

예를 들면, 본 발명의 출원인이 이전에 출원한 특허등록출원 제87130호(2005. 9. 16, 이하 '종래기술'이라 함)와 같은 기술을 들 수 있다. 상기한 종래기술은 관로(1) 속에 넣어 보수작업을 수행하는 무인보수기(2)에 관한 것으로, 무인보수기(2)의 양단 중 적어도 일단에 구비된 공압실린더 형태의 구동수단(3)과, 이 구동수단(3)에 연결된 수직 바(3a) 및 수평 바(3b), 그리고 수평 바(3a) 끝단에 구비된 스키 또는 바퀴 형태의 지지수단(4)을 기술적 구성으로 한다.For example, a technology such as Patent Registration Application No. 87130 previously filed by the applicant of the present invention (September 16, 2005, hereinafter referred to as 'prior art') may be mentioned. The prior art relates to an unmanned repair machine (2) for carrying out maintenance work in the pipeline (1), the driving means (3) of the pneumatic cylinder type provided on at least one end of both ends of the unmanned repair machine (2), and The vertical bar (3a) and the horizontal bar (3b) connected to the drive means 3, and the support means (4) in the form of skis or wheels provided at the ends of the horizontal bar (3a) is a technical configuration.

상기한 종래기술은 공압실린더와 같은 구동수단(3)을 이용하여 수직 바(3a)의 높이조절이 가능하므로 보수작업에 걸리는 시간을 단축함으로써, 인건비와 같은 비용을 절감할 수 있는 등의 효과가 있다.Since the height of the vertical bar 3a can be adjusted by using the driving means 3 such as a pneumatic cylinder, the above-mentioned conventional technology can reduce the time such as labor cost by reducing the time required for repair work. have.

그러나 지지수단(4)의 경우, 바퀴 또는 스키와 같은 두 가지 형태로 구비되어 작업환경에 따라 갈아끼워야 하는 문제점이 있다. 즉, 관로(1) 간의 연결부위 등에 상당한 크기의 틈이 형성된 경우, 바퀴 형태의 지지수단(4)은 틈 사이에 빠져 진행 및 후퇴가 어려운 상황이 발생하게 되므로 스키와 같은 지지수단(4)으로 교체해야 하는 문제점이 있다.However, in the case of the support means 4, there are problems to be replaced in accordance with the working environment is provided in two forms, such as wheels or skis. That is, when a gap of a considerable size is formed in the connection portion between the conduits 1, the support means 4 in the form of wheels fall between the gaps, so that it is difficult to proceed and retreat to the support means 4 such as skiing. There is a problem that needs to be replaced.

이때, 지지수단(4)의 교체시간만큼 보수작업에 걸리는 시간이 더 연장될 뿐만 아니라, 스키 형태의 지지수단(4)은 관로(1)에 접하는 면이 미끄러지면서 진행할 때, 노면과의 마찰이 발생하게 되므로 전력 소비효율이 떨어지거나, 작업자가 직접 당길 때에는 인력의 소모가 많아질 수밖에 없는 문제점이 있다.At this time, the time required for the maintenance work by the replacement time of the support means 4 is further extended, and the support means 4 of the ski type has a friction with the road surface when the surface contacting the conduit 1 proceeds while sliding. Since the power consumption efficiency is lowered, or when the worker directly pulls, there is a problem that the consumption of manpower is inevitably increased.

본 발명은 상기한 종래기술의 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 상·하수관의 연결부위 등에 형성된 단차나 이격으로 인한 틈새 등과 같은 주행 상의 장애를 용이하게 극복함으로써, 주행을 계속할 수 있도록 구비된 콘크리트 상·하수관용 차륜장치를 제공하기 위한 것이다.The present invention has been made to solve the above problems of the prior art, an object of the present invention is to easily continue driving by overcoming driving obstacles such as gaps caused by gaps or gaps formed in the connection portion of the water and sewage pipes. It is to provide a wheel device for the concrete water and sewage pipes.

상기한 목적을 달성하기 위한 본 발명의 콘크리트 상·하수관용 차륜장치는 주행 노면의 상태에 따라 미끄럼마찰(sliding friction)과 굴림마찰(rolling friction)을 병행할 수 있도록 이루어진 것에 핵심적인 특징이 있다.Wheel apparatus for concrete water and sewage pipes of the present invention for achieving the above object is a key feature that is made to be able to perform sliding friction and rolling friction in parallel depending on the state of the road surface.

이하, 본 발명의 바람직한 실시형태에 따른 구성을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the configuration according to a preferred embodiment of the present invention will be described in detail.

도 2에서 도시한 바와 같이, 본 발명에 따른 콘크리트 상·하수관용 차륜장치는 몸체(10)와 그 하단부 일측에 구비된 휠 부재(20)로 이루어진다. 상기한 몸체(10)는 볼트 등으로 결합할 수 있는 체결공(11)이 구비된 장방형의 판 형태로, 선단(先端) 및 후단(後端)이 곡면(12)으로 이루어진다.As shown in FIG. 2, the wheel apparatus for a concrete water and sewage pipe according to the present invention includes a body 10 and a wheel member 20 provided at one side of a lower end thereof. The body 10 is in the form of a rectangular plate provided with a fastening hole 11 that can be coupled with a bolt or the like, the front end and the rear end is made of a curved surface (12).

몸체(10) 양단에 형성된 곡면(12)은 상·하수관의 단차로 인한 높이 차이를 극복하기 위한 것으로, 몸체(10) 선후(先後) 양단으로 볼록하게 만곡된 면으로 형성된다. 즉, 몸체(10)의 곡면(12)은 상·하수관의 단차나 돌기와 같은 높이에 따른 장애 발생시, 이를 타고 넘을 수 있는 형태로 이루어진다.Curved surface 12 formed at both ends of the body 10 is to overcome the height difference due to the step of the water and sewage pipe, it is formed as a convex curved surface at both ends of the body (10). That is, the curved surface 12 of the body 10 is formed in the form that can ride over, when a failure occurs according to the height, such as a step or projection of the water and sewage pipe.

본 발명의 휠 부재(20)는 주행 상의 장애가 없는 곳에서 노면과의 마찰저항을 줄임으로써, 전동기를 이용한 견인시 소비전력을 줄이고, 작업자가 직접 견인할 때에도 과도한 인력소모를 방지한다. 구체적으로 휠 부재(20)는 금속재나 합성수지재 또는, 고무재로 이루어진 것으로, 베어링(21)이 포함된 롤러 형태 또는, 베어링(21)과 바퀴살 및 바퀴테가 구비된 형태 등 다양하게 실시할 수 있다. 바람직하게는 금속재질의 베어링(21)이 포함된 롤러를 복수로 구비하여, 몸체(10)의 앞뒤 균형이 잘 유지될 수 있도록 한다. The wheel member 20 of the present invention reduces the frictional resistance with the road surface where there is no obstacle in driving, thereby reducing the power consumption during towing using an electric motor, and prevents excessive manpower consumption even when the operator directly tow. Specifically, the wheel member 20 is made of a metal material, synthetic resin material, or rubber material, it can be carried out in a variety of forms, such as a roller shape with a bearing 21, or a shape provided with a bearing 21 and a spokes and wheel frame have. Preferably, a plurality of rollers including a metal bearing 21 are provided, so that the front and rear balance of the body 10 can be maintained well.

그리고 휠 부재(20)는 도면에서처럼 볼트와 같은 것에 의해 체결된 형태 내지는 몸체(10) 하단부에 소정의 축(軸)을 형성하고 이에 체결된 형태 등 다양하게 실시될 수 있다. 이때, 휠 부재(20)는 도 3에서 도시한 바와 같이 몸체(10) 하단으로부터 돌출되는 높이 "A"가 휠 부재(20)에 의한 굴림마찰(rolling friction)이 가능한 범위 내에서 최대한 작게 형성함으로써, 상·하수관의 노면에 형성된 홈과 같은 곳에 휠 부재(20)가 빠질 때, 소정 깊이 이상으로 빠지는 것을 방지할 수 있도록 한다. 또, 상기한 장방형의 판은 길이가 짧은 쪽보다는 긴 쪽을 가로로 채택함으로써, 상·하수관의 노면에 형성된 다양한 홈의 길이에 대해 보다 더 폭 넓게 대처할 수 있도록 하는 형태로도 좋다.In addition, the wheel member 20 may be implemented in various ways, such as a form fastened by a bolt or the like to form a predetermined shaft at the lower end of the body 10 and fastened thereto. At this time, the wheel member 20 has a height "A" protruding from the lower end of the body 10 as shown in Figure 3 by forming as small as possible within the range that the rolling friction (rolling friction) by the wheel member 20 When the wheel member 20 falls out, such as a groove formed on the road surface of the water and sewage pipe, it can be prevented from falling out more than a predetermined depth. In addition, the rectangular plate may be formed so as to cope with the length of various grooves formed on the road surface of the water and sewage pipes by adopting the long side horizontally rather than the short side.

몸체(10)의 외측 하단부 즉, 휠 부재(20)가 체결되는 해당부위에는 소정 깊이로 함몰된 홈 형태의 휠 하우징(13)이 구비되어, 휠 부재(20)가 몸체(10)의 휠 하우징(13)에 의해 소정의 깊이만큼 함몰된 형태로 이루어진 것이 좋다. 이러한 휠 하우징(13)은 장착시 몸체(10) 외측으로 휠 부재(20)가 돌출되는 정도를 최소화함으로써, 주행시 상·하수관의 내벽이나 다른 돌출물과의 충돌 가능성을 줄이고, 휠 부재(20)를 보호할 수 있게 된다.The outer lower end of the body 10, that is, the corresponding portion to which the wheel member 20 is fastened is provided with a wheel housing 13 having a groove shape recessed to a predetermined depth, and the wheel member 20 is a wheel housing of the body 10. It is preferable to have a shape recessed by a predetermined depth by (13). The wheel housing 13 minimizes the extent to which the wheel member 20 protrudes out of the body 10 when mounted, thereby reducing the possibility of collision with the inner wall of the water and sewage pipes or other protrusions while driving the wheel member 20. You can protect it.

나아가, 볼트 및 너트를 이용하여 휠 부재(20)를 체결하는 경우, 휠 하우징(13) 내에 구비된 통공의 내주면 상에는 소정의 나사산을 형성함으로써, 너트의 풀림에 관계없이 나사산에 의해 볼트의 체결상태가 유지될 수 있도록 하는 것이 좋다. 특히, 통공 내주면의 나사산은 볼트의 체결상태를 견고하게 함으로써, 작동시 휠 부재(20)의 울렁거림과 같은 유동을 방지하는 역할을 하게 된다.Furthermore, when the wheel member 20 is fastened using a bolt and a nut, a predetermined thread is formed on the inner circumferential surface of the through hole provided in the wheel housing 13, so that the bolt is fastened by the thread regardless of the loosening of the nut. It is good to ensure that is maintained. In particular, the thread of the inner circumferential surface of the through hole solidifies the fastening state of the bolt, thereby preventing the flow, such as the rumbling of the wheel member 20 during operation.

상기와 같이 구성된 본 발명의 바람직한 실시형태에 따른 작동관계를 첨부된 도면을 참조하여 설명하면 다음과 같다.Referring to the accompanying drawings, the operation of the preferred embodiment of the present invention configured as described above is as follows.
