본 고안은 중장비 등의 무한궤도식 주행장치인 슈에 관한 것으로, 특히 굽힘강성이 훨등히 뛰어나 슈가 강한 하중에 의해 휘어지는 것을 방지할 수 있을 뿐만 아니라 습지같은 곳에서 미끄러지는 것을 방지할 수 있도록 된 무한궤도용 슈에 관한 것이다.The present invention relates to a shoe which is an endless track type traveling device such as heavy equipment. In particular, the bending stiffness is much superior, which prevents the shoe from being bent under a strong load, and also prevents sliding in wetlands. It is about a dragon shoe.
건설중장비나 농업기계, 특수수송기계에 채용되고 있는 무한궤도에서는 트랙슈가 여러개의 슈(shoe)들이 연속적으로 열결된 구조로 되어, 작업환경이나 차량의 중량에 따른 각종 피로나 충격 인장 및 마모하중 등에 견딜수 있도록 만들어지면서 일정한 요철을 갖춘 슈가 장착되고 있으나, 이는 포장도로와 같이 지반이 단단한 곳에서의 작업과 주행시에 슈의 요철부가 지면을 파고 들도록 되어 있기 때문에 보도블럭이나 포장도로가 파손된다고 하는 결점이 있었다.In the endless track used in construction equipment, agricultural machinery, and special transportation equipment, the track shoe has a structure in which several shoes are continuously connected, and various fatigue, impact tension, and abrasion loads according to the working environment or the weight of the vehicle Although it is made to withstand and is equipped with a shoe having a certain unevenness, this is a defect that the sidewalk block or the pavement is damaged because the uneven part of the shoe is to be dug into the ground during work and driving in a hard ground such as a pavement. there was.
한편 이와 같은 결점을 해소하기 이해 종래에도 무한궤도에 장착되는 슈를 순수한 폴리우레탄 재질로 만든 무한궤도용 평면형 슈가 제안되어 있기도 한 바, 즉 제4도는 제5도에 도시되어 있는 바와 같이, 슈(M)의 저면(11)쪽에 제1보강판(12)이, 상면(13)쪽에는 보울트구멍 (14)에 단턱(15)이 형성되도록 제2보강핀(16)이 각각 매립되고, 상면(13)과 저면(11)사이의 측면이 경사면(17, 18)을 이루면서, 그중 경사면(17) 이 제1경사면(19)과 제2경사면(20) 및 제3경사면(21)으로 이루어지는 한편, 경사면(18)에는 보강돌기(22)가 돌출형성시켜진 구조로 되어 있다.On the other hand, in order to solve such drawbacks, conventionally, an orbital flat shoe made of pure polyurethane material has been proposed, that is, as shown in FIG. The second reinforcing pins 16 are embedded in the bottom surface 11 of M) so that the first reinforcing plate 12 is formed, and the upper surface 13 is formed with the stepped holes 15 in the bolt hole 14, respectively. 13, and the side surface between the bottom surface 11 forms the inclined surfaces (17, 18), wherein the inclined surface (17) consists of the first inclined surface 19, the second inclined surface 20 and the third inclined surface (21), The inclined surface 18 has a structure in which the reinforcement protrusions 22 protrude.
따라서 슈(M)의 저면(11)을 무한궤도위에 올려놓고 슈(M)의 보울트구멍(14)과 무한궤도에 뚫려진 보울트구멍이 일치되도록 하여 보울트체결하게 되면, 상면(13)쪽에 위치한 제2보강판(16)이 와셔역할을 하게 되므로써, 중장비가 장시간 사용되어도 보울트구멍(14)이 보호될 수 있는 한편, 굴곡이 심하거나 불규칙한 지형때문에 슈(M)가 어느정도 휘어지게되더라도 제1및 제2보강판(12, 16)의 탄성에 의해 즉시 복원되게 됨으로써 파손이 방지될 수 있게 된다.Accordingly, when the bottom 11 of the shoe M is placed on the endless track and the bolt hole 14 of the shoe M coincides with the bolt hole drilled in the endless track, the bolt is fastened, and the first side of the shoe M is located on the upper surface 13 side. Since the reinforcing plate 16 acts as a washer, the bolt hole 14 can be protected even when heavy equipment is used for a long time, while the shoe M may be bent to some extent due to severe bent or irregular terrain. By being immediately restored by the elasticity of the two reinforcing plates (12, 16) it is possible to prevent breakage.
그러나 이상과 같은 종래의 슈에 있어서는 제1및 제2보강판(12, 16)이 서로 독립적으로 설치되게 됨으로써, 슈(M)가 길이방향으로 휘지않도록 하는 굽힘강성이 약할 뿐만 아니라, 저면과 접촉되는 면이 평면으로 되어있어서 습지같은 곳에서는 쉽게 미끄러지게 되는 결점이 있었다.However, in the conventional shoe as described above, since the first and second reinforcing plates 12 and 16 are installed independently of each other, not only the bending rigidity that the shoe M is not bent in the longitudinal direction is weak, but also the bottom surface is in contact with the bottom surface. The flanks were flat, which made it easy to slide in wetlands.
이에 본 고안은 상기와 같은 결점을 해소하기 위해 안출된 것으로, I형 보강제가 슈의 내부에 매립설치되는 한편, 지면과의 접촉면에는 보울트체결부위까지 길이 방향홈이 형성됨으로써, 굽힘강성이 월등이 뛰어날 뿐만아니라, 습지같은 곳에서도 미끄러지지 않도록된 무한궤도용 슈를 제공함에 목적이 있다.The present invention has been devised to solve the above-mentioned drawbacks, while the type I reinforcement is embedded in the shoe, while the longitudinal contact grooves are formed on the contact surface with the ground, so that the bending rigidity is excellent. Not only is it excellent, but it also aims to provide a caterpillar shoe that does not slip in wetlands.
상기와 같은 목적을 달성하기 위한 본 고안은, 트랙의 링크에 조립하기 위한 보울트구멍이 중앙부에 형성된 무한궤도용 폴리우레탄 슈에 있어서, 내부에 I형보강재가 매립되어 형성되면서 상부면중앙에는 양쪽 끝에서 보울트구멍 앞까지 길이 방향홈이 형성된 구조로 되어 있다.The present invention for achieving the above object, in the endurance polyurethane shoe formed in the center of the bolt hole for assembling the link of the track, I-shaped reinforcement is formed inside the both ends at the top surface It has a structure in which a longitudinal groove is formed from the bolt hole to the front of the bolt hole.
이하 본 고안을 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안이 적용된 중장비의 개략도이고, 제2도는 본 고안 무한궤도용 슈의 사시도로써, 무한궤도의 트랙슈는 같은 구조의 슈(1)가 다수개 연결된 구조로 되어 있는바, 즉 제2도에 도시된 바와같이 폴리우레판 재질로 된 슈(1)의 내부에 I형보강재(2)가 매립되어서 중앙부에는 중장비의 무한궤도링크에 체결하기 위한 보울트구멍(3)이 형성되어 있다. 또 슈(1)가 지면과 접촉하는 상부면(4)에는 양쪽 끝에서 중앙쪽으로 보울트구멍(3)부근까지 길이방향홈(5)이 형성되어 있다.1 is a schematic view of the heavy equipment to which the present invention is applied, and FIG. 2 is a perspective view of the shoe for the caterpillar track of the present invention, wherein the track shoe of the caterpillar has a structure in which a plurality of shoes 1 of the same structure are connected to each other. As shown in FIG. 2, the I-shaped reinforcement 2 is embedded in the shoe 1 made of polyurethane, and a bolt hole 3 for fastening to the caterpillar link of heavy equipment is formed in the center portion. Moreover, the longitudinal groove 5 is formed in the upper surface 4 in which the shoe 1 contacts the ground from the both ends to the vicinity of the bolt hole 3.
이와 같이 구성된 본 고안은 무한궤도용 슈는, 무한궤도의 링크에 장착하는 경우 그에 형성된 보울트구멍(3)을 통해 체결보울트와 너트를 가지고 체결시켜 장착하게 되는데, 이 경우 슈(1)의 내부에 I형 보강재(2)가 매립되어져 있어서 단단히 조여질 수 있게 될 뿐만 아니라, 굽힘강성이 월등하기 때문에 하중에 의해 길이방향으로 휘어지는 것이 유효하게 방지될수 있게 된다.According to the present invention configured as described above, the caterpillar shoe is fastened to the caterpillar through a bolt hole (3) formed therein to be mounted by fastening a bolt and a nut. Since the I type reinforcement 2 is buried, not only can it be tightened firmly, but also the bending rigidity is excellent, and it can effectively prevent bending in the longitudinal direction by the load.
여기서 상기 I형보강재(2)의 재질로서는 일반 강철이나 섬유강화플라스틱인 고분자계 복합재료가 쓰여지는 한편, 슈(1)의 재질로서는 폴리우레탄이나 기타 적당한 강도를 갖는 고무재를 사용하게 된다.As the material of the type I reinforcing material 2, a polymer-based composite material of ordinary steel or fiber-reinforced plastic is used, while the material of the shoe 1 is made of polyurethane or other rubber material having suitable strength.
한편 슈(1)의 지면과 접촉되는 상부면(4)에는 양쪽 끝에서 중앙으로 보울트구멍(3)부근까지 길이방향홈(5)이 형성되어 있어서 습지등에서 작업을 할 경우 미끄러짐에 따른 작업효율저하가 방지될 수 있게 된다.On the other hand, the upper surface (4) in contact with the ground of the shoe (1) is formed with a longitudinal groove (5) from both ends to the vicinity of the bolt hole (3) in the center to reduce the work efficiency due to slip when working in wetlands, etc. Can be prevented.
