Description

연결장치의 구조{STRUCTURE OF QUICK COUPLER OR QUICK HITCH}Structure of connecting device {STRUCTURE OF QUICK COUPLER OR QUICK HITCH}

본 고안은 토목및 건설공사에서 사용하는 건설기계에 작업장치를 연결, 분리 시킬때 손으로 하지않고 동력을 이용하여 쉽고 빠르게 할수 있는 연결장치의 구조에 관한 것으로서, 보다 상세하게는 하자의 요소를 제거하여 강도를 향상시킴으로연결장치의 파괴를 방지할수 있도록 된 새로운 연결장치의 구조에 관한 것이다.The present invention relates to the structure of the connecting device that can be easily and quickly by using power without connecting the work device to the construction machine used in civil engineering and construction work, more specifically, to remove the defects The present invention relates to a structure of a new connecting device that can prevent the destruction of the connecting device by improving its strength.

일반적으로, 종래의 연결장치의 구조는 도 1에 도시한 바와 같이, 연결장치는 핀(1,2)으로 건설기계에 연결되고 작업장치의 핀(3)에 연결장치의 지지쇠(4)를 위치시키고 건설기계에서 공급되는 유압이 호스(5)를 통하여 실린더(6)를 신장시키면 걸쇠(7)가 작업장치의 타단 핀(8)에 접촉되므로 작업장치를 연결하게 되며, 실린더(6)를 압축시키면 걸쇠(7)가 핀(8)에서 이격되고 핀(3)에서 연결장치의 지지쇠(4)를 이탈시키면 작업장치가 분리되는데, 핀(1,2)을 지지하는 상부판(9)과 지지쇠(4), 실린더(6), 걸쇠(7)을 지지하는 하부판(11) 그리고 상부판(9)과 하부판(11)을 용접으로 결합하는 중간판(10)으로 구성된다.In general, the structure of the conventional connecting device is shown in Figure 1, the connecting device is connected to the construction machine with pins (1, 2) and the support (4) of the connecting device to the pin (3) of the working device When the hydraulic pressure supplied from the construction machine extends the cylinder 6 through the hose 5, the latch 7 contacts the other end pin 8 of the work device, thereby connecting the work device. Compression causes the catch 7 to be spaced apart from the pin 8 and the support device 4 is released from the pin 3 to separate the work tool, the top plate 9 supporting the pins 1 and 2. And the support plate 4, the cylinder 6, the lower plate (11) for supporting the clasp (7) and the upper plate (9) and the lower plate (11) to the intermediate plate (10) by welding.

이때, 연결장치는 건설기계의 힘을 작업장치에 전달하고 작업장치의 작동시 작업장치를 지탱해야 하므로 충분한 강도를 유지하여야 한다.At this time, the connecting device must maintain sufficient strength because it transfers the power of the construction machine to the working device and must support the working device during operation of the working device.

한편, 이 종래의 연결장치는 상부판(9), 중간판(10), 하부판(11)이 겹침으로 용접되어 용접부의 강도가 저하되고, 특히 고 하중을 받는 (가)부위의 강도가 저하되어 용접부가 파괴되는 문제점이 있었다.On the other hand, in the conventional connection device, the upper plate 9, the intermediate plate 10, and the lower plate 11 are welded in an overlapping manner, thereby reducing the strength of the welded portion, and in particular, the strength of the (a) portion that is subjected to high load is reduced. There was a problem that the weld is destroyed.

그리고, 건설기계나 작업장치와의 간섭으로 (가)부위에서 중간판(10)이 앞쪽으로 커질수가 없으므로 상부판(9)과 중간판(10) 사이에 겹침 구석부(12)가 형성되고, 중간판(10)과 하부판(11) 사이에 겹침 구석부(13)가 형성되어 단면적의 급격한 변화와 단면적의 축소로 용접부가 파괴되고 상부판(9)이 파괴되는 문제점이 있었다.In addition, since the intermediate plate 10 may not grow forward in the (a) part due to the interference with the construction machine or the work device, an overlapping corner portion 12 is formed between the upper plate 9 and the intermediate plate 10. The overlapping corner portion 13 is formed between the intermediate plate 10 and the lower plate 11, so that the welding part is destroyed and the upper plate 9 is destroyed due to the sudden change of the cross-sectional area and the reduction of the cross-sectional area.

또, 상부판(9)에 중간판(10)을 점선과 같이 확대시켜 겹침으로 용접되므로 상부판(9) 자체의 강성은 약간 향상되나, 건설기계의 작동시 상부판(9)의 흔들림은 충분히 방지하지 못하여 용접 접합부가 파괴되는 문제점이 있었다.In addition, since the intermediate plate 10 is welded by overlapping the middle plate 10 to the upper plate 9 as a dotted line, the stiffness of the upper plate 9 itself is slightly improved, but the shaking of the upper plate 9 during operation of the construction machine is sufficient. There was a problem that the weld joint is broken due to failure to prevent.

본 고안은 상기의 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 구조를 변경하여 강도를 향상시켜서 파괴가 발생되지 않도록 된 새로운 연결장치의 구조를 제공하는 것이다.The present invention is to solve the above problems, it is an object of the present invention to provide a structure of a new connection device to change the structure to improve the strength so that no breakage occurs.

본 고안에 따르면, 연결장치의 구조에 있어서 상부판(39)과 하부판(41) 사이에 중간판(40)을 수평으로 개재시키고, 중간판(40)을 건설기계나 작업장치에 간섭되지 않는 위치로 (나)부위와 같이 굽힘으로 형성하여 앞쪽으로 확대시키고 상부판(39)과 하부판(41)도 중간판(40)에 적절히 맞도록 앞쪽으로 확대되게 형성시키며, 상부판(39)과 중간판(40)이 보강판(42)으로 용접 결합된 것을 특징으로 하는 연결장치의 구조가 제공된다.According to the present invention, the intermediate plate 40 is horizontally interposed between the upper plate 39 and the lower plate 41 in the structure of the connecting device, the position of the intermediate plate 40 does not interfere with the construction machine or work equipment It is formed by bending as in the (b) part and enlarged to the front, and the upper plate 39 and the lower plate 41 are also formed to be extended to the front to properly fit the middle plate 40, the upper plate 39 and the middle plate A structure of a connecting device is provided, characterized in that 40 is welded to the reinforcing plate 42.

이하, 본 고안의 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도 2는 본 고안에 따른 연결장치의 구조를 예시한 것이다.2 illustrates the structure of a connection device according to the present invention.

도 2에서 연결장치는 핀(31,32)으로 건설기계에 연결되고 작업장치의 핀(33)에 연결장치의 지지쇠(34)를 위치시키고 건설기계에서 공급되는 유압이 호스(35)를 통하여 실린더(36)를 신장시키면 걸쇠(37)가 작업장치의 타단 핀(38)에 접촉되므로 작업장치를 연결하게 되고, 실린더(36)를 압축시키면 걸쇠(37)가 핀(38)에서 이격되고 핀(33)에서 연결장치의 지지쇠(34)를 이탈시키면 작업장치가 분리된다.In FIG. 2, the connecting device is connected to the construction machine by pins 31 and 32, and the supporting device 34 of the connecting device is placed on the pin 33 of the working device, and the hydraulic pressure supplied from the construction machine is supplied through the hose 35. When the cylinder 36 is extended, the clasp 37 contacts the other end pin 38 of the working device, thereby connecting the working device. When the cylinder 36 is compressed, the clasp 37 is spaced apart from the pin 38 and the pin Detaching the support bracket 34 of the connecting device at 33 separates the working device.

이때, 연결장치의 상부판(39)과 하부판(41) 사이에 중간판(40)을 수평으로 개재시켜 상부판(39)과 중간판(40) 그리고 중간판(40)과 하부판(14)이 면 접촉으로 용접 결합되어 용접부의 강도가 크게 향상되는 구조로 구성된다. 여기서, 중간판(40)과 실린더(36)의 간섭은 실린더(36)가 연결장치의 중간에 위치하므로 중간판(40)의 중간부에서 실린더(36)와 간섭되는 부분(43)을 도려낸다.At this time, the upper plate 39 and the intermediate plate 40 and the intermediate plate 40 and the lower plate 14 are interposed between the upper plate 39 and the lower plate 41 of the connecting device horizontally. It is composed of a structure that is welded by the surface contact, the strength of the weld is greatly improved. Here, the interference between the intermediate plate 40 and the cylinder 36 cuts out the portion 43 that interferes with the cylinder 36 at the middle of the intermediate plate 40 because the cylinder 36 is located in the middle of the connecting device. .

또, (나)부위와 같이 건설기계나 작업장치에 간섭되지 않는 위치로 중간판(40)을 굽힘으로 하여 앞쪽으로 확대시키고, 상부판(39)과 하부판(41)을 중간판(40)에 적절히 맞도록 앞쪽으로 확대시켜, 고 하중을 받는 (나)부위의 단면적의 변화를 감소시키고 단면적을 증대 시키며 중간판(40)의 강성도 높이는 구조로 구성된다.In addition, (b) the intermediate plate 40 is bent to a position where it does not interfere with the construction machine or work equipment as shown in the section, and the upper plate 39 and the lower plate 41 are extended to the intermediate plate 40. It is composed of a structure that reduces the cross-sectional area of the heavily loaded (b) area, increases the cross-sectional area, and increases the stiffness of the intermediate plate (40) by expanding forward to fit properly.

또한, 상부판(39)과 중간판(40)에 건설기계에 간섭되지 않도록 굽힘으로 된 보강판(42)을 용접으로 결합시켜 상부판(39)의 강성이 향상되고, 건설기계의 작동시 상부판(39)이 흔들리지 않는 구조로 구성된다. 여기서, 호스(35)와 보강판(42)의 간섭은 호스(35)가 연결장치의 중간부를 통과하므로 보강판(42)의 중간부에서 호스(35)와 간섭되는 부분(44)을 도려낸다.In addition, by combining the upper plate 39 and the intermediate plate 40 by bending the reinforcement plate 42 of the bending so as not to interfere with the construction machine, the rigidity of the upper plate 39 is improved, the upper portion during operation of the construction machine The plate 39 is composed of a structure that is not shaken. Here, the interference between the hose 35 and the reinforcing plate 42 cuts out the portion 44 that interferes with the hose 35 at the middle of the reinforcing plate 42 because the hose 35 passes through the middle of the connecting device. .

이상에서와 같이 본 고안에 의하면, 상부판(39)과 하부판(41)이 중간판(40)에 면 접촉으로 용접 결합되므로 용접 강도가 향상되고, 중간판(40)을 굽힘으로 하여 앞쪽으로 확대하고 상부판(39)과 하부판(41)을 중간판(40)에 맞추어 앞쪽으로 확대하여 (나)부위의 단면적의 변화를 감소시키고 단면적이 증대되어 고 하중을 충분히 지탱할수 있으며, 상부판(39)과 중간판(40)이 보강판(42)으로 용접 결합 되므로 상부판(39)의 강성이 향상되고 건설기계 작동시 상부판(39)의 흔들림이 방지되므로 용접 결합부가 보호되도록 구성하므로써, 건설기계의 힘을 작업장치에 전달하고 작업장치의 작동시 작업장치를 지탱하는 충분한 강도를 갖춘 새로운 연결장치의 구조를 제공한다.According to the present invention as described above, because the upper plate 39 and the lower plate 41 is welded to the intermediate plate 40 by surface contact, the welding strength is improved, and the intermediate plate 40 is bent to enlarge the front. The upper plate 39 and the lower plate 41 are enlarged in front of the intermediate plate 40 to reduce the change in the cross-sectional area of the part (b) and the cross-sectional area is increased to sufficiently support the high load. ) And the intermediate plate 40 is welded to the reinforcing plate 42, so that the rigidity of the upper plate 39 is improved and the weld plate is protected to prevent the shaking of the upper plate 39 during construction machine operation. It provides a new linkage structure with sufficient strength to transfer the power of the machine to the work tool and to support the work tool in the operation of the work tool.
