본 고안은 중장비에 장착되는 무한궤도의 슈우플레이트에 관한 것으로, 특히 중장비의 장시간 운행으로 슈우플레이트에 가로질러 돌출된 슈우의 양쪽측면이 마모되는 것을 보강해주도록 된 무한궤도용 슈우플레이트에 관한 것이다.The present invention relates to a caterpillar shoe plate mounted on heavy equipment, and more particularly to a caterpillar shoe plate to reinforce the wear of both sides of the shoe protruding across the shoe plate by the long run of the heavy equipment.
일반적으로 포크레인과 같은 중장비는 노면상태가 좋지않은 곳, 예컨대 암석지대나 구름지등에서 굴착등과 같은 여러가지 작업을 하는 장비로서, 이러한 중장비의 바디, 붐, 암, 버킷등의 상부구조 물을 지지 또는 이동시키는 무한궤도를 이루는 슈우를 갖춘 슈우플레이트가 불규칙한 노면상태로 인하여 집중하중을 받게 되는데, 이 경우 제3도a에 도시된 바와 같이 슈우플레이트(3)를 가로질러 돌출형성된 슈우(14)의 양쪽 모서리부(14a)에서 부터 마모가 시작되어 조금씩 둥글게 되고, 이와 같이 모서리부(14a)가 조금씩 둥글게 됨에 따라 접지압이 증가되어 마모는 더욱더 가속화 됨으로써 최종적으로 제3도의 b에 도시된 바와 같이 슈우(14) 양쪽 끝모서리(14a)가 둥글게 마모되게 된다.In general, heavy equipment such as fork cranes are equipment that performs various operations such as excavation in bad road conditions, for example, rocky or clouded areas, and supports the superstructures of such heavy equipment such as bodies, booms, arms, and buckets. A shoe plate with a shoe moving in a caterpillar is subjected to a concentrated load due to an irregular road surface state, in which case both sides of the shoe 14 protruding from the shoe plate 3 as shown in FIG. Wear starts from the corner portion 14a and is rounded little by little. As the corner portion 14a is rounded little by little, the ground pressure is increased and wear is further accelerated, so that the shoe 14 is finally accelerated as shown in b of FIG. ) Both end edges 14a are worn roundly.
상기와 같이 슈우(14)의 양쪽 모서리(14a)가 둥글게 마모된 상태에서 중장비를 주행시키게 되면, 무한궤도의 슈우플레이트(3)가 경우에 따라 노면으로 부터 미끄러지게 되어, 중장비의 주행이 원활하게 이루어지지 못하게 됨으로써 슈우플레이트(3)를 자주고체해 주어야 된다는 문제점이 있었다.As described above, when the heavy equipment is driven in a state in which both edges 14a of the shoe 14 are worn round, the track plate 3 of the endless track slides from the road surface in some cases, so that the heavy equipment travels smoothly. There was a problem in that the shoe plate (3) to be frequently solidified by not being made.
이에 본 고안은 상기와 같은 제반 문제점을 해소하기 위해 안출된 것으로서, 중장비의 무한궤도를 이루는 슈우프러레이트를 가로질러 사각막대형태로 돌출형성된 슈우의 양끝에 역사다리꼴 형태의 돌기부를 형성시켜줌으로써, 슈우플레이트에 돌출된 슈우의 양끝부분이 중간부보다 넓게 확장됨에 따라 슈우의 양끝부분이 쉽게 마모되지 않아 슈우플레이트의 적정사용수명을 연장시킬 수 있도록한 무한궤도용 슈우플레이트를 제공함에 그 목적이 있다.Therefore, the present invention was conceived to solve the above problems, by forming an inverted trapezoidal protrusion at both ends of the shoe formed in a rectangular bar shape across the sprue forming the endless track of heavy equipment, As both ends of the shoe protruding from the shoe plate are wider than the middle part, the end of the shoe is not easily worn so that the endless track shoe plate can be extended to extend the proper service life of the shoe plate. .
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 무한궤도용 슈우플레이트는 제1도 내지 제2도에 도시된 바와 같이, 중장비(1)의 무한궤도(2)를 이루도록 장착되는데, 이 슈우플레이트(3)에 양쪽 끝부위에 역사다리꼴형상인 돌기부(5)가 구비된 I자형상의 슈우(4)가 가로질러 돌출형성된 구조로 되어 있다.In the present invention, the track plate for crawling tracks is mounted to form the track 2 of the heavy equipment 1, as shown in FIGS. 1 to 2, and the inverted trapezoidal trapezoid at both ends of the swing plate 3 is shown. The I-shaped shoe 4 provided with the protrusion 5 in shape has a structure in which it protrudes across.
상기와 같이 구성된 본 고안에 따른 슈우플레이트(3)를 갖춘 중장비(1)가 주행할 때에 노면으로 부터 제4도 a에 도시된 바와 같이 압축력(F1)과 전단력(F2, F3)이 슈우(4)와 돌기부(5)에 각각 작용하게 되는데, 이 경우 본 고안에 따른 슈우(4)의 폭(W)과 길이(ℓ)가 제4도 b 에 도시된 바와 같이, 종래 1자형 슈우(14)의 폭(W1)과 깊이(ℓ1)와 각각 같은 동시에 동일한 제질로 형성된다고 가정하면, 슈우(4)의 길이방향에 따른 단면적(A)은 종래 슈우(14)의 단면적(A1)보다 크게 되고, 본 고안의 슈우(4)와 종래 슈우(14)에 동일한 압축력(F1)이 작용한다고 가정하면, 압축응력(σ)은 작용력에 비례하는 반면에 단면적에 반비례하게 되므로, 본 고안에 따른 슈우(4)의 압축응력(σ:σ=F1/A)은 상대적으로 종래 슈우(14)의 압축응력(σ1: σ1=F1/A1)보다 작아지게되며, 또한 동일한 전단력(F2, F3)이 각각 슈우(4, 14)에 작용한다고 가정하면, 본 고안에 따른 슈우(4)의 전단응력(τ : τ=F2/A또는 F3/A) 또한 종래 슈우(14)의 전단응력(τ1: τ1=F2/A1또는 F3/A)보다 상대적으로 낮아져, 슈우(4)의 내마모성과 내구서이 향상되게 됨으로써 슈우(4)의 양쪽 모서리부분이 빨리 마모되는 것이 방지되게 된다.When the heavy equipment 1 equipped with the shoe plate 3 according to the present invention configured as described above travels, the compressive force F 1 and the shear force F 2 and F 3 are reduced from the road surface as shown in FIG. It acts on the shoe 4 and the projection 5, in this case, the width (W) and the length (L) of the shoe 4 according to the present invention, as shown in Figure 4 b, the conventional single-shaped shoe Assuming that the width W 1 and the depth L 1 of the 14 are each formed at the same time and the same material, the cross-sectional area A along the longitudinal direction of the shoe 4 is the cross-sectional area A of the conventional shoe 14. 1 ), and assuming that the same compressive force F 1 acts on the shoe 4 and the conventional shoe 14 of the present invention, the compressive stress σ is inversely proportional to the cross-sectional area while proportional to the acting force. The compressive stress (σ: σ = F 1 / A) of the shoe 4 according to the present invention is relatively smaller than the compressive stress (σ 1 : σ 1 = F 1 / A 1 ) of the conventional shoe 14, Also Assuming that the same shear forces (F 2 , F 3 ) act on the shoes 4, 14, respectively, the shear stress (τ: τ = F 2 / A or F 3 / A) of the shoe 4 according to the present invention is also It is relatively lower than the shear stress (τ 1 : τ 1 = F 2 / A 1 or F 3 / A) of the conventional shoe 14, thereby improving the wear resistance and durability of the shoe 4, thereby improving both edges of the shoe 4 The part will be prevented from wearing out quickly.
이상에서 설명한 바와 같이 본 고안의 무한궤도(2)를 이루는 슈우플레이트(3)에 역사다리꼴 형태의 돌기부(5)를 갖는 슈우(4)가 가로질러 돌출형성됨으로써, 무한궤도(2)가 미끄러지지 않고 정속주행하게 할 수 있을 뿐만 아니라 슈우(4)의 양끝이 가운데 보다 빨리 마모되는 것을 방지하게 되는 효과가 있다.As described above, the shoe 4 having the inverted trapezoidal protrusion 5 is formed to protrude across the shoe plate 3 forming the caterpillar 2 of the present invention, so that the caterpillar 2 does not slip. Not only can it drive at constant speed, but both ends of the shoe 4 are prevented from being worn out faster than the center.
