본 고안은 산업용차량에 장착되어 사용되는 멀티타인(MULTI TINE)의 흔들림을 방지하기 위한 멀티타인장치에 관한 것이다.The present invention relates to a multi-tine device for preventing the shake of the multi-tine (MULTI TINE) used in the industrial vehicle.
일반적으로 멀티타인은 작업물을 위치이동시켜 상, 하차 및 인양작업을 하는데 사용하는 장비로 제3도에 나타낸 것과 같다.In general, multi-tine is a equipment used to move the work position, lifting, unloading and lifting as shown in Figure 3.
그 고정위치나 방법을 보면 산업용차량의 아암(11) 일단에 핀(111)에 의해 고정된다.In view of the fixing position and method, the pin 111 is fixed to one end of the arm 11 of the industrial vehicle.
따라서, 상기 멀티타인(120)은 굴삭기 아암(110)의 상, 하동작에도 항상 자중에 의한 연직방향의 복원력을 갖게 된다.Accordingly, the multi-tine 120 always has a restoring force in the vertical direction due to its own weight even when the excavator arm 110 moves up and down.
작업중 반복되는 아암(110)의 상, 하 및 회전운동으로 인해 상기 멀티타인(120)은 상기 복원력에 의해 심한 흔들림이 발생하게 된다.Due to the repetitive up, down, and rotational movement of the arm 110 during the operation, the multi-tine 120 is severely shaken by the restoring force.
이러한 멀티타인(120)의 심한 흔들림은 작업물이 이탈할 우려가 있어 작업속도를 지연시키게 되며 정교한 위치 선정작업이 불가능하였다.Severe shaking of the multi-tines 120 may cause the work to be separated, thereby delaying the work speed and making precise positioning work impossible.
또한, 작업물의 이탈로 인한 추락이나 작업물의 심한 요동은 장비는 물론 작업자에게 안전사고에 대한 불안감을 가져왔었다.In addition, the fall caused by the fall of the workpiece or the severe fluctuation of the workpiece has caused anxiety for safety accidents as well as equipment.

본 고안의 구성 및 작용효과를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.The construction and effect of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안이 산업용차량에 장착된 위치를 나타낸 사용상태도를 나타낸 것이다.Figure 1 shows a state diagram showing the position of the subject innovation mounted on the industrial vehicle.
그 구성을 보면 산업용차량의 아암수단의 일단에 링크수단으로 연결되어 멀티타인(MULTI TINE : 20)에서 링크(21)와 차량의 아암(10)의 하부에 소정거리를 두고 유압완충수단(30)이 연결된다.The configuration is connected to one end of the arm means of the industrial vehicle as a link means in the multi-tine (MULTI TINE 20) at a predetermined distance in the lower portion of the link 21 and the arm 10 of the vehicle hydraulic buffer means (30) Is connected.
제2도는 상기 유압완충수단(30)의 구성을 나타낸 것으로 실린더(31)와 피스톤(32) 및 피스톤로드(33)와 상기 프스톤의 운동을 제어하는 유압 제어부를 구성된다.2 is a view showing the configuration of the hydraulic buffer means 30, the cylinder 31, the piston 32 and the piston rod 33 and the hydraulic control unit for controlling the movement of the proston.
상기 유압제어부는 제1유압제어부와 제2유압제어부로 나누어진다.The hydraulic controller is divided into a first hydraulic controller and a second hydraulic controller.
제1유압제어부는 실린더(31)내의 피스톤(32) 전실부에서 후실부로 연결되어 일방향으로만 흐르도록 한 제1유압라인(35)과 상기 제1유압라인(35)과 같은 구성을 갖되 상반된 방향을 갖는 제2유압라인(36)으로 구성된다.The first hydraulic control unit has the same configuration as that of the first hydraulic line 35 and the first hydraulic line 35 connected to the rear chamber from the front chamber of the piston 32 in the cylinder 31 to flow only in one direction. And a second hydraulic line 36 having a direction.
상기 제1, 제2유압라인(35), (36)은 각기 체크밸브를 사용하여 역방향 유체의 흐름을 차단한다.The first and second hydraulic lines 35 and 36 block the flow of reverse fluid by using check valves, respectively.
상기 제2유압제어부는 상기 피스톤(32)의 전실, 후실부의 유체가 유통할 수 있는 소정크기의 통공(32a)으로 형성된다.The second hydraulic controller is formed of a predetermined size through-hole 32a through which the fluid of the front and rear chambers of the piston 32 can flow.
상기 통공(32a)은 상기 체크밸브가 동작되는 일정압력 이하에서만 작용하도록 소정 직경으로 적어도 1개이상 형성한다.At least one through-hole 32a is formed to have a predetermined diameter so that the check valve operates only under a predetermined pressure at which the check valve is operated.
제3도와 제4도는 본 고안의 동작관계를 도시한 것으로 그 동작관계를 살펴보면 다음과 같다.3 and 4 illustrate the operation relationship of the present invention. The operation relationship is as follows.
산업용 차량의 아암(10)이 상승하게 되면 그 일단에 메달려 있던 멀티타인(20)은 연직방향으로 복귀하려는 F1의 힘이 작용하게 되고 그 힘은 유압완충수단(30)에 F1'의 힘으로 변화되어 전달된다(제3도(a)참조).When the arm 10 of the industrial vehicle is raised, the multi-tine 20 hanging at one end thereof acts as a force of F1 to return to the vertical direction, and the force is changed by the force of F1 'to the hydraulic buffer means 30. (See Figure 3 (a)).
유압완충수단에 전달된 F1'의 힘은 피스톤(32)을 밀어 유체를 압축시키면서 일정압력이상일때 체크밸브를 열어 제1유압라인(35)을 통해 흐르게 된다(제3도(b) 참조).The force of F1 'transmitted to the hydraulic buffer means is to flow through the first hydraulic line 35 by opening the check valve when a certain pressure or more while pushing the piston 32 to compress the fluid (see Fig. 3 (b)).
이때 제2유압라인(36)은 닫혀 있는 상태를 유체의 흐름이 차단된다.At this time, the flow of the fluid is blocked in the closed state of the second hydraulic line 36.
상기 F1'의 힘이 일정압력 이하일 경우에는 제2유압제어부인 통공(32)을 통해 압유가 흐르도록 한다.When the force of F1 'is below a predetermined pressure, the hydraulic oil flows through the through hole 32, which is the second hydraulic control unit.
상기와 같은 작용으로 상기 멀티타인(20)의 연직방향 복귀력은 상기 유압완충수단(30)을 통해 서서히 완충 지연되면서 흔들림이 방지되는 것이다.The vertical return force of the multi-tines 20 by the above-described action is to prevent the shake while slowly buffering delay through the hydraulic buffer means (30).
제4도는 작업중 산업용차량의 아암(10)이 하강된 경우로 멀티타인(20)과 유압완충수단(30)에 각각 F2와 F2'이 작용하게 된다(제4도(a) 참조).FIG. 4 illustrates the case where the arm 10 of the industrial vehicle is lowered during operation, so that F2 and F2 'act on the multi-tine 20 and the hydraulic shock absorber 30 (see FIG. 4 (a)).
이때 피스톤(32)은 F2'의 힘으로 이완되면서 압류를 제1유압조절부인 제2유압라인(36)을 통해 밀어내게 되고 일정 압력이하에서는 앞서 설명한 바와같은 제2유압조절부인 통공(32)으로 유통시킨다(제4도(b) 참조).At this time, the piston 32 is pushed through the second hydraulic line 36, which is the first hydraulic pressure control unit, while being relaxed by the force of F2 ', and below a predetermined pressure to the second hydraulic pressure control unit hole 32 as described above. Circulation (see FIG. 4 (b)).
이상과 같은 작용으로 본 고안은 멀티타인이 연직방향 복귀되는 힘을 완충지연시킴으로써 멀티타인이 진자운동되는 것을 억제시키게 된다.With the above-described action, the present invention suppresses pendulum movement of the multi-tine by buffering the force in which the multi-tine returns in the vertical direction.
따라서, 본 고안은 작업시간을 단축시킬 수 있음은 물론 정교한 작업을 실현시킬 수 있다.Therefore, the present invention can shorten the working time and can realize sophisticated work.
또한 본 고안은 작업물의 유동이 없어 이탈이나 추락을 방지하게 되므로 작업자의 안전을 도모할 수 있는 이점이 있다.In addition, the present design has the advantage that can be prevented from falling or falling because there is no flow of the workpiece to promote the safety of the worker.
이상과 같은 작용효과를 갖는 본 고안은 연직방향의 복귀력을 갖는 산업장비에 장착 사용되어 같은 효과를 거둘 수 있다.The present invention having the above-described effects can be mounted and used in industrial equipment having a vertical return force to achieve the same effect.
