크레인 받침대 {Crane Pads}Crane Pads {Crane Pads}

본 발명은 크레인 받침대에 관한 것으로, 좀 더 상세하게 설명하면 크레인차량에서 기중기 작업시 안정성 확보를 위해 사방으로 전개하는 아우트리거의 잭 하부에 깔아 지반침하, 차량전도, 도로파손을 방지하는 크레인 받침대에 관한 것이다.The present invention relates to a crane pedestal, and more specifically, to a crane pedestal that is laid under the jack of the outrigger that is deployed in all directions to secure stability when working with a crane in a crane vehicle to prevent ground subsidence, vehicle overturning, and road damage. it's about

크레인 받침대는 크레인 차량의 잭에 걸리는 하중을 지면에 넓게 분산하여 지반침하, 차량전도, 도로파손을 방지하기 위한 것이다. The crane pedestal is to prevent ground subsidence, vehicle overturning, and road damage by dispersing the load applied to the jack of the crane vehicle widely on the ground.

일반적으로 구하기 쉬운 목재를 사용하는데 쉽게 파손되는 문제점이 있다.In general, there is a problem in that it is easily damaged by using wood that is easy to obtain.

또는 일정두께의 철판을 잘라 사용하는 경우가 있는데 목재보다 강하고 튼튼하지만 무게가 무거워 운반 및 설치가 힘들다. 특히 땅이나 도로 바닥에 깔린 무거운 철판을 철거할 때 지렛대로 들어올릴 틈을 만들기 위해 땅이나 도로의 일부를 파낼 경우가 있어 도로파손을 방지하는 본래 목적에 어긋나게 된다.Alternatively, a certain thickness of steel plate is cut and used. It is stronger and stronger than wood, but it is heavy and difficult to transport and install. In particular, when removing a heavy iron plate laid on the ground or road floor, a part of the ground or road may be dug to make a gap for lifting with a lever, which goes against the original purpose of preventing road damage.

또한 목재나 철판으로 대용한 크레인 받침대는 손잡이가 없으므로 들다가 놓치기 쉬워 사용자의 발이 깔리는 등 사고위험성이 있다.In addition, the crane pedestal substituted with wood or steel plate does not have a handle, so it is easy to miss it while lifting, and there is a risk of accidents such as the user's feet being crushed.

본 발명은 이러한 문제점을 해결하기 위하여, 상하판에 지지판을 설치하여 다수의 중공을 형성함으로써 가벼우면서도 충분한 강도를 가지고, 손잡이가 있어 취급이 용이한 크레인 받침대를 제공하는 것을 목적으로 한다.In order to solve this problem, an object of the present invention is to provide a crane support that is light and has sufficient strength by forming a plurality of hollows by installing support plates on the upper and lower plates, and has a handle and is easy to handle.

본 발명은 지지판(140)으로 다수의 중공을 형성하여 가볍고 튼튼하며, 다양한 규격으로 쉽게 제작할 수 있는 크레인 받침대를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a crane pedestal that is light and strong by forming a plurality of hollows with the support plate 140 and can be easily manufactured in various specifications.

도1과 도2에서 보듯이 본 발명은 알루미늄 등의 금속을 압출하여 일정길이로 자른 두개 이상의 본체(100)를 조인트바(200)로 결합한다. 이렇게 결합한 본체(100)의 전면 및 후면의 중공을 막도록 한쌍의 커버(400)를 구성한다.As shown in FIGS. 1 and 2 , in the present invention, two or more main bodies 100 cut to a predetermined length by extruding metal such as aluminum are combined with a joint bar 200 . A pair of covers 400 are configured to block the hollow of the front and rear surfaces of the combined body 100 .

손잡이(500)의 볼트부(510)를 커버(400)의 손잡이결합공(410)에 삽입하여 너트(520)로 체결한다. 이렇게 손잡이(500)가 결합된 커버(400)를 본체(100)의 전면과 후면에 용접하고, 본체(100)의 하부면에 조인트바(200)와 직각방향으로 다수의 평철(600)을 용접한다. The bolt portion 510 of the handle 500 is inserted into the handle coupling hole 410 of the cover 400 and fastened with a nut 520 . In this way, the cover 400 to which the handle 500 is coupled is welded to the front and rear surfaces of the main body 100 , and a plurality of flat irons 600 are welded to the lower surface of the main body 100 in a direction perpendicular to the joint bar 200 . do.

본 발명에서는 조인트바(200)로 결합된 부분이 잭(20)의 수직압력에 상대적으로 취약하므로, 커버(400)와 평철(600)을 조인트바(200)와 직각으로 교차하도록 구성하여 이러한 구조적 취약점을 해소한다.In the present invention, since the portion coupled to the joint bar 200 is relatively vulnerable to the vertical pressure of the jack 20, the cover 400 and the flat iron 600 are configured to intersect the joint bar 200 at a right angle to this structural eliminate vulnerabilities.

도3을 참조하여 본체(100), 조인트바(200), 미끄럼방지고무(300)의 구조와 결합방법에 대해 자세히 설명한다.The structure and coupling method of the main body 100, the joint bar 200, and the non-slip rubber 300 will be described in detail with reference to FIG. 3 .

본체(100)를 정면에서 보면 상판(110), 하판(120), 측판(130), 지지판(140)으로 이루어진 장방형의 구조이다. 이러한 구조대로 알루미늄 등의 금속을 압출하여 본체(100)를 전후방향으로 길게 성형해서 필요한 길이만큼 잘라 크레인 받침대(10)를 제작한다.When the main body 100 is viewed from the front, it has a rectangular structure consisting of an upper plate 110 , a lower plate 120 , a side plate 130 , and a support plate 140 . By extruding metal such as aluminum according to this structure, the main body 100 is molded long in the front-rear direction, and cut to the required length to manufacture the crane pedestal 10 .

다수의 지지판(140)은 본체(100) 내부의 공간을 구획하여 다수의 중공을 형성한다. 지지판(140)의 주된 역할은 중공을 형성하여 본체(100)를 경량화하면서도, 본체(100)가 크레인 차량의 무게에 찌그러지지 않고 잘 견디며, 잭(20)에 집중된 힘을 지면에 효과적으로 분산하여 지반침하를 방지하는 것이다.The plurality of support plates 140 divide the space inside the body 100 to form a plurality of hollows. The main role of the support plate 140 is to form a hollow to lighten the body 100, while the body 100 withstands the weight of the crane vehicle well without being crushed, and effectively dispersing the force concentrated on the jack 20 to the ground to prevent subsidence.

본체(100)의 전후길이는 압출성형으로 얼마든지 길게 성형할 수 있으나, 좌우길이를 늘리는 것은 금형의 크기 때문에 한계가 있다. The front and rear length of the body 100 can be molded as long as possible by extrusion molding, but increasing the left and right length is limited due to the size of the mold.

따라서 본 발명은 조인트바(200)로 다수의 본체(100)를 체결하여 좌우길이의 한계를 극복함으로써 다양한 규격의 크레인 받침대(10)를 쉽게 제작하는 것이 특징이다.Therefore, the present invention is characterized in that the crane pedestal 10 of various standards can be easily manufactured by overcoming the limit of the left and right lengths by fastening a plurality of the main bodies 100 with the joint bar 200 .

크레인 받침대(10)를 눈이나 비가 오는 날 다소 비탈진 지면에서 사용할 경우 상판(110)에 닿은 잭(20)이 미끄러져 사고로 이어질 가능성이 있다.When the crane pedestal 10 is used on a slightly sloping ground on a snowy or rainy day, the jack 20 in contact with the top plate 110 may slip and lead to an accident.

따라서 잭(20)이 쉽게 미끄러지지 않도록 상판(110)에 돌출부(112)를 형성한다. 또한 마찰력을 더욱 증대하기 위해 요철부(310)가 형성된 미끄럼방지고무(300)를 결합하면 미끄러짐을 확실히 방지하므로 안전성이 향상된다. 만일 미끄럼방지고무(300)가 노후화되어 찢어지거나 벗겨져도 돌출부(112)가 노출되어 미끄럼방지기능을 지속적으로 수행할 수 있다.Accordingly, the protrusion 112 is formed on the upper plate 110 so that the jack 20 does not easily slide. In addition, when the anti-slip rubber 300 with the uneven portion 310 is combined to further increase the frictional force, the slipping is definitely prevented, and thus the safety is improved. If the non-slip rubber 300 is torn or peeled off due to aging, the protrusion 112 is exposed to continuously perform the anti-slip function.

참고로 본 발명은 크레인 받침대(10)의 바닥면이 지면과 접촉할 때 흙에 밀리지 않도록 본체(100)의 하부면에 평철(600)을 다수 부설하여 요철을 형성하므로 미끄럼방지기능이 추가되어 더욱 안전하다.For reference, in the present invention, when the bottom surface of the crane pedestal 10 is in contact with the ground, a plurality of flat irons 600 are laid on the lower surface of the main body 100 to form irregularities so as not to be pushed by the soil. safe.

도4에서 보듯이 조인트바(200)의 돌기결합부(210)를 본체(100)의 요홈결합부(131)에 삽입하고, 미끄럼방지고무(300)에 형성된 고무돌기부(320)를 상판(110)의 고무결합홈(111)에 삽입하여 결합한다. As shown in FIG. 4 , the protrusion coupling part 210 of the joint bar 200 is inserted into the groove coupling part 131 of the main body 100 , and the rubber protrusion part 320 formed in the non-slip rubber 300 is applied to the top plate 110 . ) by inserting it into the rubber coupling groove (111).

여기에 손잡이(500)가 달린 커버(400)와 평철(600)을 용접하여 크레인 받침대(10)를 완성한 후, 도5와 같이 잭(20) 밑에 설치하여 사용한다. Here, after completing the crane pedestal 10 by welding the cover 400 with the handle 500 and the flat iron 600 , it is installed and used under the jack 20 as shown in FIG. 5 .

도6과 도7은 본 발명의 다른 실시예로서, 상판(110)과 하판(120)을 사선으로 연결하도록 지지판(140)을 구성하여 직각으로 연결할 때보다 지지판(140) 숫자를 최소화하면서 잭(20)의 압력을 충분히 견디고, 측판(130)에 형성된 요홈결합부(131) 숫자를 변경하여 크레인 받침대(10)의 두께를 다르게 제작하는 것이다.6 and 7 are another embodiment of the present invention, the support plate 140 is configured to connect the upper plate 110 and the lower plate 120 in an oblique line, and the number of the support plate 140 is minimized while minimizing the number of jacks ( 20) to sufficiently withstand the pressure, and to vary the thickness of the crane pedestal 10 by changing the number of the groove coupling portion 131 formed on the side plate 130.

도8은 본 발명의 또다른 실시예로서, 본체(100)의 중공에 스티로폼 등의 발포폼(150)을 채워 넣고 지지판(140)의 두께를 줄인 것이다. 8 is another embodiment of the present invention, the thickness of the support plate 140 is reduced by filling the hollow of the body 100 with foam 150 such as Styrofoam.

발포폼(150)은 한 점에 집중된 힘에는 쉽게 손상되지만 넓은 면적에 가해지는 힘과 압력에는 매우 강한 특성을 가지고 있어 충격흡수재나 포장재로 널리 쓰인다. 따라서 금속으로 된 지지판(140)의 두께를 줄이고 금속보다 가벼운 발포폼(150)을 채워 넣으면 더욱 가볍고 튼튼한 구조로 만들 수 있다.The foam 150 is easily damaged by the force concentrated on one point, but has a very strong characteristic to the force and pressure applied to a large area, so it is widely used as a shock absorber or packaging material. Therefore, if the thickness of the metal support plate 140 is reduced and the foam 150 lighter than the metal is filled, it can be made into a lighter and stronger structure.

이로써 본 발명은 가볍고 견고한 구조를 가지며 전후좌우길이 및 두께가 다른 다양한 규격의 크레인 받침대(10)를 제공한다.Accordingly, the present invention provides a crane pedestal 10 of various standards having a light and strong structure and having different lengths and thicknesses in front and rear.
