Description
본발명은 대형 화물차 및 버스용 타이어 탈장착시 이용되는 보조 잭The present invention is an auxiliary jack used when the tires for heavy trucks and buses
에 관한 것으로, 특히 무게가 많이 나가는 타이어를 세운 상태로 타이어 탈장착 위치로 이동시킨다음 타이어를 승하강시켜 타이어 교체를 용이하게한 것에 관한 것이다.In particular, the present invention relates to an easy tire replacement by moving a tire up and down in a state where a heavy tire is placed up and down.
일반적으로 자동차의 타이어를 교체할 때 먼저 차량을 잭으로 들어올린 다음 타이어를 직접 손으로 들어서 나사부에 결합시킨다음 렌치로 너트를 잠거 교체하여 왔다.In general, when replacing a tire of a car, first lift the vehicle with a jack, then manually lift the tire by hand, attach it to the screw, and then lock and replace the nut with a wrench.
그러나 대형 화물차나 버스에 장착되는 타이어는 무게가 많이 나가는 데도 불구하고 작업자가 직접 들어서 타이어를 교체해야하므로 힘도 많이 들고 또한 허리 디스크나 요통과 같은 신체적으로 안전 사고가 발생하는 일이 빈번히 일어날 뿐만 아니라 타이어 교체 시간이 늦어지는 문제점이 있었다.However, tires mounted on large trucks or buses are not only heavy, but also require heavy lifting and replacement of tires. There was a problem that the tire replacement time is late.
상기와 같은 문제점을 해결하기 위한 본발명은 대형 화물차나 버스에 타이어를 탈장착할 때 작업자의 허리 디스크와같은 신체적 사고발생을 방지하고 또한 타이어의 탈장착시 편리하면서도 용이하게할 수 있도록한 데 목적을 둔다.The present invention to solve the above problems is to prevent the occurrence of physical accidents, such as the worker's waist disk when the tire is mounted on a large truck or bus, and also to make it convenient and easy to remove the tire. .
상기의 목적을 달성하기 위한 본 발명의 기술적 과제는, 대형 화물차나 버스의 타이어를 넘어지지 않도록 직립으로 세워 타이어 교체 위치로 간편히 이동시킬 수 있고 또 타이어를 제위치에 결합되도록 승강시킬 수 있게 조정할 수 있는 보조 잭을 제공하므로서 그 목적은 달성된다.The technical problem of the present invention for achieving the above object is to stand upright so as not to fall over the tire of a large truck or bus, can be easily moved to the tire replacement position, and can be adjusted to raise and lower the tire to fit in position The objective is achieved by providing an auxiliary jack.

It is a structure which has the bearing block 9 to which the 8 is fastened.
상기 지지간(3)은 크로스되게하여 그 중심부가 힌지로 체결되고 하단에는 상기 본체(2)의 가이드 홀(7)에서 안내되어지는 가이드봉(6)이 설치되며, 상기 가이드봉(6)의 중앙에는 나사구멍(10)을 형성하여 지지간(3)을 절접되게하는 조절 나사봉(8)이 나사결합되게한 구성이다.The support section (3) is to be cross, the center of which is fastened to the hinge and the guide rod (6) guided in the guide hole (7) of the main body (2) is installed at the lower end of the guide rod (6) In the center, a screw hole 10 is formed so that the adjusting screw rod 8 for cutting the support bar 3 is screwed together.
한편, 상기 가동 플레이트(4)는 상면 중앙부에 길이 방향으로 사각홈(11)을 형성하되 양단부에는 타이어 고정부(5)와 나사결합되어 타이어 고정부(5)를 전후로 이동되게하는 조절 나사봉(8a)이 삽설되는 베어링 블록(9a)이 설치되며, 양측벽에는 상기 지지간(3)의 상단부에 체결된 가이드봉(6a)이 안내되도록 가이드홀(7a)을 형성한 구성이다.On the other hand, the movable plate 4 is formed with a square groove (11) in the longitudinal direction in the center of the upper surface, but screwed with the tire fixing portion (5) at both ends to adjust the screw rod for moving the tire fixing portion (5) back and forth ( The bearing block 9a in which 8a) is inserted is installed, and the guide hole 7a is formed in both side walls so that the guide rod 6a fastened to the upper end of the said support part 3 is guided.
또한, 상기 타이어 고정부(5)는 사각홈(11)에 입설되어 하부에는 조절 나사봉(8a)이 나사결합되도록 나사구멍(12)을 가지고 상부 양측으로 나사홈(13)이 형성된 지지판(14)을 가지며 상기 지지판(14)의 상부 나사홈(13)으로 90도로 절곡된 지지로드(15)를 나사결합하되, 상기 지지로드(15)에는 다수의 로울러(16)가 설치된 구성이다.In addition, the tire fixing part 5 is installed in the square groove 11, the lower plate has a screw hole 12 so that the adjustment screw rod (8a) is screwed to the support plate 14 formed with the screw groove 13 on both sides of the upper And screwing the support rod 15 bent by 90 degrees to the upper screw groove 13 of the support plate 14, wherein the support rod 15 has a plurality of rollers 16 installed therein.
상기의 지지판(14)에 결합된 지지 로드(15)는 상하로 회전시켜 좌우로 가변되도록한 구성이다.The support rod 15 coupled to the support plate 14 is configured to be varied vertically by rotating up and down.
또한, 상기 본체(2)에 설치된 지지간(3)의 조절 나사봉(8)과 가동 플레이트(4)에 설치된 타이어 고정부(5)의 조절 나사봉(8)은 일측에 손잡이(8b)가 달린 핸들(8c)이 부착되고, 나사봉의 중앙부를 기점으로 왼나사부와 오른나사부로 형성하여 타이어 고정부(5)가 조절 나사봉(8)의 중앙을 향하여 전후로 이동되도록한 구성이다.In addition, the adjustment screw rod 8 of the support rod 3 installed on the main body 2 and the adjustment screw rod 8 of the tire fixing part 5 installed on the movable plate 4 have a handle 8b on one side thereof. The handle 8c with which it is attached is formed, and it is the structure which made the tire fixation part 5 move back and forth toward the center of the adjustment screw rod 8 by forming the center part of a screw rod from the left screw part and the right screw part.
이와같이 구성된 본발명의 작용 효과를 설명하면 다음과 같다.The effect of the present invention configured as described above is as follows.
도2에 도시된 바와 같이 타이어(100)를 가동 플레이트(4)의 타이어 고정부(5) 사이에 세운다음 조절 나사봉(8a)의 핸들(8c)을 회전시키면 조절 나사봉(8a)을 회전되면서 나사봉(8a)에 나사결합된 타이어 고정부(5)가 타이어쪽을 향하여 이동된다.As shown in Fig. 2, the tire 100 is placed between the tire fixing portions 5 of the movable plate 4, and then the handle 8c of the adjusting screw rod 8a is rotated to rotate the adjusting screw rod 8a. While being fixed, the tire fixing part 5 screwed to the screw rod 8a is moved toward the tire side.
이와같이 이동된 타이어 고정부(5)의 로울러(16)가 타이어(100)에 견착되도록 나사 결합된 지지로드(15)를 회전하여 뚜께를 조절한다.The roller 16 of the tire fixing part 5 moved as described above is rotated to adjust the thickness by rotating the support rod 15 which is screwed to be attached to the tire 100.
이와같이 타이어(100)를 지지시킨 타이어 받침 보조 잭을 버스나 대형 화물차의 바퀴를 장착할 위치로 이동시킨 다음, 본체(2)에 설치된 조절 나사봉(8)을 시계도는 방향으로 회전하면 조절 나사봉(8)에 나사결합된 가이드 봉(6)이 가이드 홀(7)(7a)에 안내되어 중앙부를 향하여 이동되면서 가이드 봉(6)의 양단부에 크로스 결합된 지지간(3)이 수직방향으로 이동되면서 가동 플레이트(4)는 승강된다.In this way, the tire support auxiliary jack supporting the tire 100 is moved to the position where the wheel of a bus or a large truck is to be mounted, and then the adjustment screw rod 8 installed on the main body 2 is rotated clockwise to adjust the adjustment. The guide rods 6 screwed to the four rods 8 are guided to the guide holes 7 and 7a and moved toward the center portion, while the support rods 3 cross-coupled to both ends of the guide rods 6 are vertically moved. The movable plate 4 is elevated while being moved.
이 때 타이어를 탈장착시킬 수 있는 제위치까지 승강되도록 하여 타이어를 에어 공구로 탈장착하면 되는 것이다.At this time, the tire is lifted to a position where the tire can be attached and detached, and the tire can be removed by an air tool.
상기와 같은 본발명은 무게가 무거운 타이어를 탈장착할 때 작업자에게 빈번히 발생하는 허리 디스크와같은 신체적 사고를 미연에 예방하고 또한 타이어의 탈장착을 편리하면서도 용이토록함과 동시에 타이어 교체시간을 단축할 수 있는 효과를 있게한 것이다.As described above, the present invention prevents physical accidents such as a lumbar disc that frequently occurs when an operator removes and replaces a heavy tire, and also makes it easy and convenient to remove and reduce tire replacement time. It made an effect.
