Description

굴삭기용 투스{TOOTH FOR EXCAVATOR} Tooth for excavator {TOOTH FOR EXCAVATOR}

본 발명은 굴삭기용 투스에 관한 것으로서, 더욱 상세하게는 바위나 목재 등과 같은 물체를 집어 올릴 때 집어 올린 물체를 보다 안정적으로 움켜쥘 수 있도록 개선된 구조를 이루는 굴삭기용 투스에 관한 것이다.The present invention relates to a tooth for an excavator, and more specifically, to a tooth for an excavator that has an improved structure to more stably grip the picked object when picking up an object such as a rock or wood.

일반적으로 건설공사 현장에서 사용되는 굴삭기는, 버킷(Bucket)을 이용한 지반의 굴착이나 토사를 적재 및 운반하는 작업, 크러셔(Crusher)를 이용한 건물 파쇄 및 철근 절단 작업, 브레이커(Breaker)를 이용한 암석 및 콘크리트 파괴 작업, 그랩(Grab)을 이용한 고철이나 암석, 목재 등의 중량물 운반 작업 등, 그 용도에 따라 여러 종류의 어태치먼트(Attachment)를 서로 교체하여 다양한 작업을 수행할 수 있다.Excavators generally used at construction sites include excavating the ground using a bucket, loading and transporting earth and sand, crushing buildings and cutting rebar using a crusher, and cutting rocks and other materials using a breaker. Various tasks can be performed by replacing various types of attachments depending on the purpose, such as concrete destruction work or transporting heavy objects such as scrap metal, rocks, or wood using a grab.

이때, 고철이나 암석, 목재 등과 같은 중량물을 운반하고자 할 때에는 굴삭기에 한 쌍의 그랩을 어태치먼트로 장착시켜 사용하는데, 이하에서는 첨부된 도면을 참조하여 한 쌍의 그랩이 장착되는 구조에 대하여 상세히 설명한다.At this time, when transporting heavy objects such as scrap metal, rocks, wood, etc., a pair of grabs are used as attachments on the excavator. Below, the structure in which the pair of grabs are mounted will be described in detail with reference to the attached drawings. .

도 1은 한 쌍의 그랩이 장착된 구조를 도시하는 측면도이고, 도 2는 한 쌍의 그랩이 장착된 구조를 도시하는 사시도이다.Figure 1 is a side view showing a structure equipped with a pair of grabs, and Figure 2 is a perspective view showing a structure equipped with a pair of grabs.

굴삭기로 중량물을 운반하고자 할 때에는 도 1 및 도 2에 도시된 바와 같이 한 쌍의 그랩(10)을 회전 가능한 구조로 장착시켜, 상기 한 쌍의 그랩(10)을 벌리거나 오므리는 동작을 통해 중량물을 움켜쥘 수 있도록 한다. 이때, 상기 그랩(10)이 철근이나 암석 등과 같은 중량물에 직접 접촉되면 상기 그랩(10)이 손상되거나 파손될 수 있는바, 그랩(10)의 끝단에는 본 실시 예에 도시된 바와 같이 다수 개의 투스(20)가 장착된다.When transporting a heavy object with an excavator, a pair of grabs 10 are mounted in a rotatable structure as shown in FIGS. 1 and 2, and the heavy object is moved by opening or closing the pair of grabs 10. So that you can grab it. At this time, if the grab 10 is in direct contact with heavy objects such as reinforcing bars or rocks, the grab 10 may be damaged or broken. As shown in this embodiment, the end of the grab 10 has a plurality of teeth ( 20) is installed.

그러나 종래에 상용화되어 있는 투스(20)는 외측면이 매끈한 평면으로 형성되어 있으므로, 한 쌍의 그랩(10)으로 중량물을 움켜쥐었을 때 상기 그랩(10)의 끝단 즉, 투스(20)가 장착된 부위에 걸린 중량물은 아래로 미끄러져 떨어지는 경우가 발생된다는 단점이 있다. 이와 같이 일부 중량물이 투스(20)에 걸리지 아니하고 아래로 미끄러져 떨어지면, 한 쌍의 그랩(10)으로 한 번에 움켜쥘 수 있는 중량물의 수량이 감소되는바, 중량물 운반작업의 효율이 현저히 저하된다는 문제가 발생된다.However, since the conventionally commercialized tooth 20 has a smooth outer surface, when a heavy object is grasped with a pair of grabs 10, the end of the grab 10, that is, the tooth 20, is attached. The disadvantage is that heavy objects caught in the affected area may slip down and fall. In this way, if some heavy objects do not catch on the teeth (20) and slip down, the number of heavy objects that can be grabbed at one time with a pair of grabs (10) is reduced, and the efficiency of heavy object transport work is significantly reduced. A problem arises.

이하, 본 발명의 구체적인 실시 예를 첨부 도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the accompanying drawings.

본 발명의 실시 예는 여러 가지 형태로 변형될 수 있으며, 본 발명의 범위가 아래에서 상세히 설명하는 실시 예로 한정되는 것으로 해석되어서는 안 된다. 본 실시 예는 당 업계에서 평균적인 지식을 가진 자에게 본 발명을 더욱 완전하게 설명하기 위하여 제공되는 것이다.Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This example is provided to more completely explain the present invention to those with average knowledge in the art.

따라서, 도면에서 표현한 구성요소의 형상 등은 더욱 명확한 설명을 강조하기 위해서 과장되어 표현될 수 있다. 각 도면에서 동일한 구성은 동일한 참조부호로 도시한 경우가 있음을 유의하여야 한다. 또한, 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 공지 기술의 기능 및 구성에 관한 상세한 설명은 생략될 수 있다.Accordingly, the shapes of components expressed in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same configuration may be indicated by the same reference numeral in each drawing. Additionally, detailed descriptions of the functions and configurations of known technologies that are judged to unnecessarily obscure the gist of the present invention may be omitted.

먼저, 본 발명의 일 실시 예에 따른 굴삭기용 투스의 구조를 도 3 내지 도 7을 통해 살펴보면 다음과 같다.First, the structure of the excavator tooth according to an embodiment of the present invention is as follows through FIGS. 3 to 7.

본 실시 예에서의 굴삭기용 투스는, 굴삭기 그랩(10)에 일정 간격으로 용접 구성된 다수의 어댑터(30)에 개별적인 삽입 결합이 이루어질 수 있도록 삽입홈(110)이 형성된 투스 본체(100)와, 상기 투스 본체(100)의 후단부에 관통 형성되어 체결핀(300)의 체결이 이루어지는 핀 체결공(120)과, 상기 투스 본체(100)에 돌출 구비된 돌기부(200)와, 상기 삽입홈(110) 내부에 구성되어 어댑터(30)의 위치 지지가 이루어지는 지지볼(130)과, 상기 지지볼(130)을 탄성 지지하는 탄성스프링(140)의 구성을 이룬다.The excavator tooth in this embodiment includes a tooth body 100 in which an insertion groove 110 is formed to allow individual insertion and coupling to a plurality of adapters 30 welded to the excavator grab 10 at regular intervals, and A pin fastening hole 120 formed through the rear end of the tooth body 100 through which the fastening pin 300 is fastened, a protrusion 200 protruding from the tooth body 100, and the insertion groove 110. ) It consists of a support ball 130 that is installed inside to support the position of the adapter 30, and an elastic spring 140 that elastically supports the support ball 130.

이때, 어댑터(30)의 선단부에는 지지볼(130)의 안착이 이루어지는 안착홈(31)이 반구 형상을 이루어 형성되고, 후단부에는 체결핀(300)의 체결을 위한 관통공(32)이 형성됨이 바람직하다.At this time, a seating groove 31 in which the support ball 130 is seated is formed in a hemispherical shape at the front end of the adapter 30, and a through hole 32 for fastening the fastening pin 300 is formed at the rear end. This is desirable.

이와 같은 구성을 이루는 본 발명 투스의 사용에 따른 작용효과를 살펴보기로 한다.Let us look at the effects of using the tooth of the present invention, which has this configuration.

본 발명의 굴삭기용 투스는 체결핀(300)에 의해 투스 본체(100)가 어댑터(30)에 조립 체결이 이루어짐과 함께 돌기부(200) 구성으로 인해 중량물의 안정적인 파지 상태가 유지될 수 있게 된다.In the excavator tooth of the present invention, the tooth body 100 is assembled and fastened to the adapter 30 by the fastening pin 300, and the structure of the protrusion 200 allows a stable grip of a heavy object to be maintained.

즉, 도 8 및 도 9에서 나타내어지는 바와 같이 투스 본체(100)를 어댑터(30)에 조립시킨 상태에서 체결핀(300)을 핀 체결공(120) 및 관통공(32)에 체결시킴으로써 조립이 신속하게 이루어질 수 있게 된다.That is, as shown in FIGS. 8 and 9, assembly is performed by fastening the fastening pin 300 to the pin fastening hole 120 and the through hole 32 while the tooth body 100 is assembled to the adapter 30. It can be done quickly.

특히, 이때의 조립 과정에서는 삽입홈(110) 내부에 탄성스프링(140)에 의해 탄성 지지되는 지지볼(130)이 구비되어 있기 때문에 어댑터(30)의 체결 위치가 안내됨과 함께 안정적인 체결상태가 유지되어 내부에서 유동 발생이 방지될 수 있게 된다.In particular, in this assembly process, since the support ball 130 is elastically supported by the elastic spring 140 inside the insertion groove 110, the fastening position of the adapter 30 is guided and a stable fastening state is maintained. This prevents flow from occurring inside.

이와 같이 조립이 이루어진 투스는 표면에 돌기부(200)가 돌출 구비되어 있기 때문에 중량물에 대한 파지력이 증대됨과 함께 미끄러짐 현상을 방지할 수 있게 된다.Since the teeth assembled in this way have protruding portions 200 on the surface, the gripping force for heavy objects is increased and slipping can be prevented.

따라서 본 발명의 굴삭기용 투스는, 굴삭기에 장착되는 그랩의 마모 및 손상을 방지할 수 있으며, 상기 그랩이 움켜쥔 중량물이 하향으로 미끄러져 떨어지는 현상을 방지함으로서 중량물 운반효율을 높일 수 있다는 장점이 있다. Therefore, the excavator tooth of the present invention has the advantage of being able to prevent wear and damage of the grab mounted on the excavator, and to increase the efficiency of transporting heavy materials by preventing the heavy objects grasped by the grab from sliding downward. .

또한, 종래의 굴삭기용 투스에 비해 사용수명이 길어 유지비용을 절감시킬 수 있다는 장점이 있다.In addition, it has the advantage of having a longer service life compared to conventional excavator teeth, thereby reducing maintenance costs.

한편, 도 10 및 도 11은 본 발명의 다른 실시 예에 따른 구성을 나타낸 것으로서, 지지볼(130)과 대응되는 어댑터(30) 선단부에 형성되는 안착홈(31)은 다수개로 형성되고, 삽입홈(110)에는 어댑터(30)와의 체결위치 좌우 간격 조절이 가능하도록 간격 조절판(150)이 삽입 가능하되, 상기 삽입홈(110) 내부에는 간격 조절판(150)의 선단돌부(151)가 지지될 수 있는 다수의 조절판 지지홈(160)이 일정 간격으로 형성된다.Meanwhile, Figures 10 and 11 show a configuration according to another embodiment of the present invention, in which a plurality of seating grooves 31 are formed at the tip of the adapter 30 corresponding to the support ball 130, and the insertion groove is A spacing adjusting plate 150 can be inserted into (110) to adjust the left and right spacing of the fastening position with the adapter 30, and the tip protrusion 151 of the spacing adjusting plate 150 can be supported inside the insertion groove 110. A plurality of control plate support grooves 160 are formed at regular intervals.

또한, 간격 조절판(150)에는 어댑터(30)와의 마찰력 증대를 위한 탄소섬유 재질의 마찰브러시(151)가 구성된다.In addition, the spacing adjustment plate 150 is provided with a friction brush 151 made of carbon fiber to increase friction with the adapter 30.

이와 같은 구성을 이루게 되면, 다수의 안착홈(31) 구조를 통해 투스본체(100)의 좌우 위치 조절에 따라 안착홈(31)에 안착되는 지지볼(130)의 위치 변경이 이루어질 수 있게 되며, 조절판 지지홈(160)의 구조로 인해 간격 조절판(150)의 보다 안정적인 지지가 이루어질 수 있게 된다.When this configuration is achieved, the position of the support ball 130 seated in the seating groove 31 can be changed according to the left and right position adjustment of the tooth body 100 through the structure of the plurality of seating grooves 31, Due to the structure of the adjustment plate support groove 160, the gap adjustment plate 150 can be supported more stably.

또한, 간격 조절판(150)에는 탄소섬유 재질의 마찰브러시(151)가 형성되어 있기 때문에 마찰력 증대에 따른 어댑터(30)와의 마찰 지지력이 안정적으로 유지될 수 있게 됨을 알 수 있다. 탄소섬유는 내열성 및 내충격성이 뛰어난 소재이기 때문에 합성수지 재질의 브러시에 비해 마찰 저항성을 향상시킬 수 있게 된다.In addition, since the friction brush 151 made of carbon fiber is formed on the spacing adjustment plate 150, it can be seen that the frictional support force with the adapter 30 due to the increase in friction force can be stably maintained. Since carbon fiber is a material with excellent heat resistance and impact resistance, friction resistance can be improved compared to brushes made of synthetic resin.

또한, 도 12는 본 발명의 또 다른 실시 예에 따른 구성을 나타낸 것으로서, 삽입홈(110) 내벽면에는 어댑터(30)와의 마찰력 증대를 위한 마찰층(111)이 코팅 형성된다.In addition, Figure 12 shows a configuration according to another embodiment of the present invention, and a friction layer 111 is coated on the inner wall of the insertion groove 110 to increase friction with the adapter 30.

이때, 상기 마찰층(111)은 염화비닐수지 25~45중량%, 폴리불화비닐리덴 15~30중량%, 소듐하이드록사이드 10~30중량%, 우레탄 수지 10~30중량%, 플루오르화가돌리늄 1~15중량%, 디메치콘 1~10중량%의 비율로 혼합 조성을 이룸이 바람직하다.At this time, the friction layer 111 is composed of 25 to 45% by weight of vinyl chloride resin, 15 to 30% by weight of polyvinylidene fluoride, 10 to 30% by weight of sodium hydroxide, 10 to 30% by weight of urethane resin, and 1% dolinium fluoride. It is preferable to form a mixed composition at a ratio of ~15% by weight and 1~10% by weight of dimethicone.

이와 같은 마찰층(111)의 구성을 이루게 되면, 삽입홈(110) 내에서 어댑터(30)의 마찰력이 향상될 수 있게 되어 어댑터(30)에 체결된 상태에서 투스의 유동 및 이탈 발생이 방지될 수 있게 된다.When the friction layer 111 is configured in this way, the frictional force of the adapter 30 within the insertion groove 110 can be improved, thereby preventing the tooth from moving and coming off while fastened to the adapter 30. It becomes possible.

특히, 마찰층(111)에는 폴리불화비닐리덴 및 소듐하이드록사이드 성분이 혼합되어 있기 때문에 내구성을 향상시킴과 함께 어댑터(30)의 마찰로 인한 크랙 발생이 방지되고, 플루오르화가돌리늄은 염화비닐수지의 경화 현상을 방지하여 안정적인 탄력성을 유지시키며, 디메치콘은 마찰층(111)의 밀도 및 접착력을 향상시키는 기능을 수행하게 된다.In particular, since the friction layer 111 contains a mixture of polyvinylidene fluoride and sodium hydroxide components, durability is improved and cracks due to friction of the adapter 30 are prevented, and dolinium fluoride is a vinyl chloride resin. It maintains stable elasticity by preventing hardening, and dimethicone functions to improve the density and adhesion of the friction layer 111.

그리고, 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 굴삭기용 투스 구조가 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다. In addition, although specific embodiments of the present invention have been described and shown above, it is obvious that the tooth structure for an excavator of the present invention can be implemented in various modifications by those skilled in the art.

그러나 이와 같은 변형된 실시 예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.However, such modified embodiments should not be understood individually from the technical spirit or scope of the present invention, and such modified embodiments should be included within the scope of the appended claims of the present invention.
