Description
본 발명은 유압잭에 관한 것으로, 특히 대형차량의 액슬축 분해작업시 양측의 브레이크드럼에 각각 고정하여 차량을 지지함과 아울러 상하 승강시키기 위한 유압잭에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic jack, and more particularly, to a hydraulic jack for supporting a vehicle by being fixed to brake drums on both sides when disassembling axle shafts of a large vehicle.
일반적으로, 잭(jack)은 주로 차량의 고장으로 인한 수리 또는 점검작업시차량의 중량을 지지하고 적정 높이로 위치시키기 위한 부품이다.In general, the jack (jack) is a part mainly for supporting the weight of the vehicle during the repair or inspection work due to the failure of the vehicle and to position the proper height.
잭의 종류로는 나사의 회전력으로 중량물을 지지하는 기계식 인양잭과, 유압의 힘으로 중량물을 지지하며 승강시키는 유압잭등으로 분류된다.Types of jacks are classified into mechanical lifting jacks that support heavy objects by the rotational force of the screw, and hydraulic jacks that support and lift the heavy objects by the force of hydraulic pressure.
종래의 기계식 인양잭은 본체와, 본체의 상측에 설치되고 상단부에 중량물에 접지되는 접지받침대가 설치되는 링크기구와, 링크기구에 조작력을 제공하는 손잡이부등으로 대별된다.Conventional mechanical lifting jacks are roughly divided into a main body, a link mechanism provided on an upper side of the main body, and a ground support provided on the upper end of the main body, and a handle part for providing an operation force to the link mechanism.
이러한 인양잭은 기존 대형차량의 액슬 분해작업시 액슬의 중앙 하측면에 접지받침대를 위치시킨 후에 손잡이부를 조작하여 링크기구에 지지력을 제공하도록 되어 있다.This lifting jack is designed to provide support to the link mechanism by manipulating the handle after placing the grounding base on the center lower side of the axle when dismantling axles of existing large vehicles.
그런데, 종래 인양잭은 차량의 액슬과 접지받침대의 접지면적이 서로 작아서 작업중 작은 충격에도 전후 좌우로 이탈되어 안전사고가 발생할 우려가 높았다.However, the lifting jack of the related art has a high possibility that a safety accident may occur because the ground areas of the axle and the grounding base of the vehicle are small from each other, and thus they are separated from the front, rear, left, and right sides even during a small impact during operation.
그리고, 초보자일 경우 접지받침대를 정확한 액슬의 하측면에 위치시키는 위치선정작업에 애로점이 있으며, 또 위치를 잘못 선정한 경우 다른 부품에 무리한 무게가 가해져 부품이 파손될 우려가 있었다.And, if you are a beginner, there is a problem in the positioning operation for positioning the grounding base on the lower side of the correct axle, and if the wrong position is selected, there is a risk that the parts are damaged due to excessive weight on other parts.
본 발명은 상기한 제반문제점을 감안하여 안출된 것으로, 그 목적은 간편하면서 정확하게 접지위치를 선정할 수 있으며, 작업중 진동이 발생되더라도 견고하게 지지할 수 있도록 한 유압잭을 제공하는 데 있다.The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a hydraulic jack which can be easily and accurately selected from a ground position and can be firmly supported even when vibration occurs during operation.

본 발명의 유압잭은 브레이크 드럼의 하측면에 밀착된 상태에서 지지 및 승강시키도록 수평지지대와 그 수평지지대를 승강시키는 유압실린더등을 구비함으로써, 견고하게 차량의 양측을 지지 및 승강시킬 수 있으며 충격에 의한 진동에도 이탈되지 않는 장점을 갖는다.The hydraulic jack of the present invention is provided with a horizontal support and a hydraulic cylinder for elevating the horizontal support so as to support and elevate in a state in close contact with the lower side of the brake drum, thereby firmly supporting and elevating both sides of the vehicle, and There is an advantage that does not deviate even by vibration.
이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 유압잭은, 도 1 내지 도 3 참조, 본체(11)와, 본체(11)의 상측에 수직으로 설치되며 상호 대응되는 형상을 갖는 한 조의 수직지지대(12)와, 양측이 승강가능하도록 그 수직지지대(12)의 외주면에 슬라이딩 결합되는 수평지지대(15)와, 상단부의 로드(16a)가 수평지지대(15)에 설치되고 하단부의 몸체가 본체(11)에 설치되는 유압실린더(16)로 구성된다.1 to 3, the hydraulic jack according to the present invention, the main body 11 and a set of vertical support 12 having a shape corresponding to each other and installed vertically on the upper side of the main body 11, both sides can be elevated The horizontal support 15 which is slidably coupled to the outer circumferential surface of the vertical support 12 and the hydraulic cylinder 16 in which the rod 16a of the upper end is installed in the horizontal support 15 and the body of the lower end is installed in the main body 11. It is composed of
더 상세히 설명하면, 본체(11)는 각 테두리에 바퀴(17)가 설치되어 이동가능한 구조를 가지며, 수직지지대(12)는 본체(11)의 상측에 환봉의 형태로 수직 설치되어 있다.In more detail, the main body 11 has a structure in which wheels 17 are installed at each rim and are movable, and the vertical support 12 is vertically installed in the form of a round bar on the upper side of the main body 11.
수평지지대(15)는 중앙에 브레이크 드럼(50)의 하측면 형상과 대응되는 형상의 안착홈(15a)이 형성되고, 그 안착홈(15a)의 하측에 브레이크 휠너트(55)와 결합되는 고정공(15b)이 복수개 형성되어 있다.The horizontal support 15 has a fixing groove 15a having a shape corresponding to the lower surface shape of the brake drum 50 at the center thereof, and a fixing hole coupled to the brake wheel nut 55 at the lower side of the mounting groove 15a. A plurality of 15b is formed.
즉, 수평지지대(15)는 브레이크 드럼(50)의 하측면에 안착홈(15a)이 밀착되고 고정공(15b)을 통해 휠너트(55)와 볼트(미도시)가 각각 결합되어 지지되는 구조를 갖는다.That is, the horizontal support 15 has a structure in which the seating groove 15a is in close contact with the lower side of the brake drum 50 and the wheel nut 55 and the bolt (not shown) are coupled and supported through the fixing holes 15b, respectively. Have
이를 위해 수평지지대(15)의 고정공(15b)은 휠볼트의 간격과 동일한 간격으로 적정 크기로 형성되어 있다.To this end, the fixing hole 15b of the horizontal support 15 is formed to a proper size at the same interval as the spacing of the wheel bolts.
이러한 구성을 갖는 본 발명의 작용은 다음과 같다.The operation of the present invention having such a configuration is as follows.
먼저 본 발명의 유압잭을 브레이크 드럼(50)에 조립하는 과정을 설명하면, 휠너트(55)를 풀어 타이어를 차량으로부터 이탈시킨 다음에, 브레이크 드럼(50)의 하측면에 안착홈(15a)이 밀착되도록 수평지지대(15)를 승강시켜 위치를 선정한다.First, the process of assembling the hydraulic jack of the present invention to the brake drum 50 will be described. After the wheel nut 55 is released to release the tire from the vehicle, the seating groove 15a is in close contact with the lower side of the brake drum 50. Raise and lower the horizontal support 15 to select a position.
이때, 수평지지대(15)의 고정공(15b)은 휠볼트에 관통되도록 결합시킨 후에 외측에서 휠너트(55)를 조여 체결한다.At this time, the fixing hole 15b of the horizontal support 15 is coupled to penetrate through the wheel bolt, and then tighten the wheel nut 55 from the outside.
이후에 유압실린더(16)에 유압을 제공하면, 로드(16a)가 상승되어 수평지지대(15)를 상승시키게 된다.After the hydraulic pressure is provided to the hydraulic cylinder 16, the rod (16a) is raised to raise the horizontal support (15).
여기서, 본 발명의 유압잭(10)이 차량의 양측 바퀴에 각각 하나씩 결합된 상태로 브레이크 드럼(50)을 상승시키면, 차량의 양측이 모두 지지되어 인양된다.Here, when the hydraulic jack 10 of the present invention raises the brake drum 50 in a state in which the hydraulic jack 10 is coupled to each of the wheels on both sides of the vehicle, both sides of the vehicle are supported and lifted up.
이후에 별도의 보조유압잭을 이용하여 액슬의 분해작업 또는 기타 현가장치등의 중량물을 지지함으로써, 견고하게 차량을 지지 및 승강시킬 수 있게 된다.After that, by supporting a heavy load such as disassembly work of the axle or other suspension using a separate auxiliary hydraulic jack, it is possible to firmly support and lift the vehicle.
또한, 브레이크 휠너트(55)와 볼트가 고정공(15b)을 통해 수평지지대(15)가고정 결합되어 있으므로, 작업중의 전후 및 좌우방향의 충격발생시 전달되는 진동에도 불구하고 견고하게 지지할 수 있게 된다.In addition, since the brake wheel nut 55 and the bolt are fixedly coupled to the horizontal support 15 through the fixing hole 15b, the brake wheel nut 55 and the bolt can be firmly supported in spite of the vibration transmitted when an impact occurs in the front, rear, and left and right directions during the operation. .
이상과 같이 설명한 본 발명은 차량의 양측에 고정 결합되어 작업중에 전달되는 충격에도 견고하게 지지할 수 있도록 한 유압잭에 관한 것인바, 이에 따르면 본 발명은 접지위치의 선정작업이 용이할 뿐만 아니라, 견고하게 지지할 수 있으므로 작업중의 안전사고를 예방할 수 있는 효과를 갖는다.The present invention as described above relates to a hydraulic jack that is fixedly coupled to both sides of the vehicle so that it can be firmly supported even in the impact transmitted during operation, according to the present invention not only easy to select the grounding position, but also firm Since it can be supported, it has the effect of preventing safety accidents during work.
