Description

원목작업용그랩장치{a grab system for wood work}Grab system for wood work {a grab system for wood work}

본 고안은 원목작업용그랩장치에 관한 것으로, 벌목현장에서 베어낸 원목들을 집어올리거나 내리는 그랩(grab)장치로 포크레인 유압붐에 착탈식으로 장치 되어 사용되는 장비이다.The present invention relates to a grappling device for wood work, a grab device for picking up or lowering wood cut at a logging site, and is used as a detachable device on a fork-lane hydraulic boom.

이와같은 장비에서는 포크래인의 상단붐대에 설치된 그랩장치하부는 원목이 놓인 위치에 따라 그랩장치의 집게부의 그랩방향을 선회시킬 필요가 있으며, 그랩장치로 집어올린 상태에서 차량등에 상차하거나, 현장에서 원목들을 일정방향으로 야적하는 경우나, 그랩장치에 중량이 실린체 장시간 사용하는 경우에는 그랩장치를 회전시키는 구성품에 쉽게 마모되어 수명의 단축이나 잦게 부품의 교체등의 문제점이 발생하였다.In such equipment, the lower part of the grab device installed on the upper boom of the fork lane needs to turn the grab direction of the grab part of the grab device according to the position of the wood. When they are piled up in a certain direction, or when the weight of the grab device is used for a long time, the components that rotate the grab device are easily worn, causing problems such as shortening of life and frequent replacement of parts.

특히, 상기 그랩장치를 회전시키는 수단으로 주로 워엄과 웜나사 방식으로 그랩장치 하부를 감속선회시켰는데, 워엄및 웜나사의 치차가 쉽게 마모되어 수명이 짧다는 문제점이 지적되였다. In particular, as the means for rotating the grab device, the lower part of the grab device was slowly decelerated by a worm and a worm screw method, and it was pointed out that the gears of the worm and worm screws were easily worn and short in life.

이에 본 고안장치에서는 상기와 같이 그랩장치에 있어서, 가장 취약점인 그랩장치 하부 회전수단을 내마모성이 향상되도록, 유압모터로부터 직결된 원동기어를 그랩장치 하부 회전축상에 장치한 평기어와 감속운전되게 결합하며, 그랩장치 하부의 그랩장치가 중량이 가해지는 상태에서도 원활한 축회전상태를 제공하도록하는 원목작업용그랩장치를 제공하고자 한다.In the present device, as described above, in the grab device, the vulnerable device of the grab device is coupled with the spur gear installed on the lower axis of rotation of the grab device so that the lower rotation means of the grab device has improved wear resistance. The present invention also provides a grappling device for wood work to provide a smooth shaft rotation even in a state where the grab device under the grab device is subjected to weight.

Assembling the tongs hinge shaft (4a) so that both ends of the frame can be rotated and the bent portion is opposed, the hydraulic cylinder body (6) also assembled to the cylinder hinge shaft (5a) to the left and right sides of the hydraulic cylinder fixing piece (5), The cylinder rod portion is assembled to the cylinder rod shaft 6a horizontally assembled at the curved portion of the arm clip portion 2 and the sharpener portion 3, and the shibel shaft socket 7 fixed to the bottom of the center hole of the clip base 1 Insert the lower shaft (8) into the Shibel shaft socket (9) and insert it with the Shibel shaft socket (9). It is fixed by the Shibel shaft lower stopper tab (10), the tongs base (1) is fixed above the center of the crushed Shibel shaft end jaw (8), and on the Shibel shaft (11) gear box base (protruding disc is formed in the center) 12) is pivotally assembled, the spur gear 13 is fitted, and the spur gear fixing key 13a is fixed to the shibel shaft 11, and then the double row tapered roller 14 is the shibel shaft on the spur gear 13. (11), the gearbox base upper cover (15) formed with a shibel shaft case shaft hole (15a) in the center and a hydraulic motor mounting shaft hole (15b) in one side is assembled to the gearbox base (12) and bolt (15c) Then, the Shibel shaft case shaft hole (15a) is assembled to the bolt 16b, the Shibel shaft case 16 having a bracket (16a) formed at the bottom, and the hydraulic motor 17 is bolted to the hydraulic motor installation shaft hole (15b) 17b) The spline drive gear 17a is axially coupled to the spline hydraulic motor shaft 17c which is assembled and supported by the bearing 17d up and down so as to engage with the spur gear.

도면중 미설명 부호 '18'은 포크레인 연결편이며, '19'는 쉬벨축케이스상단블럭으로 포크레인연결편(18)을 정착하는 블럭이다.In the figure, reference numeral '18' is a fork-lane connecting piece, and '19' is a block for fixing the fork-lane connecting piece 18 as a top block of the Shibel shaft case.

상기와 같이 구성된 본 고안의 일실시 작용으로는 다음과 같다.One embodiment of the present invention configured as described above is as follows.

본 고안에 따른 장착운전은 포크레인의 유압붐에 본 장치의 포크레인연결편(18)에 축결합하도록 하는것으로, 포크레인으로부터 제공되는 유압입출력라인은 쉬벨축케이스(16)측편과 쉬벨축소켓(7)좌우편에 배관되도록 한 것으로 쉬벨축케이스(16)측편으로 유압이 유입되어, 집게부가 장착된 집게베이스(1)의 회동각도에 상관없이,쉬벨축소켓(7)을 통해 집게부의 유압실린더몸체부(6)에 유압을 공급단속하도록 하는것으로, 종전에 있어서 거추장스럽게 외부로 돌출되는 유압라인을 내재시킬수 있도록 한 것이다.Mounting operation according to the present invention is to be coupled to the hydraulic boom of the fork to the fork-lane connecting piece (18) of the device, the hydraulic I / O line provided from the fork-lane side of the Shibel shaft case (16) and the left and right of the Shibel shaft socket (7) The hydraulic fluid flows into the side of the Shibel shaft case 16 so that the hydraulic cylinder flows into the hydraulic cylinder body 6 through the Shibel shaft socket 7 irrespective of the rotation angle of the forceps base 1 on which the forceps are mounted. In order to control the supply of hydraulic pressure to), it is possible to embed the hydraulic line that protrudes outwardly in the past.

한편, 포크레인 상단붐에 장착된 본 장치의 포크레인연결편(18)과 쉬벨축케이스(16)와 기어박스베이스상커버(15)는 포크레인 상단붐과 고정되여 있으나, 집게베이스(1)하방에 장착된 본 고안의 암집게부(2)와 숫집게부(3)는 쉬벨축(11)을 기준축으로 회동되는 구조이다.On the other hand, the fork-lane connecting piece 18, the shibel shaft case 16, and the gearbox base cover 15 of the device mounted on the fork-lane upper boom are fixed to the fork-lane upper boom, but are mounted below the tongs base (1). The arm clamp part 2 and the sharpener part 3 of the present invention have a structure in which the Shibel axis 11 is rotated about a reference axis.

상기에서 쉬벨베이스(1)를 회동시키는 동작은 기어박스상커버(15)상에 장착된 유압모터(17)의 정역조작에 의해 스플라인유압모터축(17c)에 축결합된 스플라인원동기어(17a)가 평기어(13)를 회전시키므로서, 쉬벨축(11) 하단축이 쉬벨축하부키(9)로 고정된 집게베이스(1)를 회동시키게 되어, 암집게부(2)와 숫집게부(3)가 장착된 집게베이스(1)가 자재로이 회동되는 것이다.In the above operation, the operation of rotating the shibel base 1 is performed by the spline hydraulic motor shaft 17c axially coupled to the spline hydraulic motor shaft 17c by the forward and reverse operation of the hydraulic motor 17 mounted on the gear box upper cover 15. While rotating the spur gears 13, the lower end shaft of the shibel shaft 11 rotates the tong base 1 fixed with the lower shibel shaft key 9, and the female clamp portion 2 and the sharpener portion 3 Clamp base (1) equipped with is rotated freely.

이와 같은 방식은 종전에 워엄과 웜나사로 쉬벨축을 회동시키는 방식으로 인해 원목 하중이 실린 집게부를 회동하는 동작에 의해 워엄나사부의 잦은 마모를 방지토록 한 것이다.Such a method prevents frequent wear of the worm screw by rotating the tongs loaded with a wooden load due to the method of rotating the shibel shaft with a worm and a worm screw.

이상과 같은 본 고안은 그동안 원목장업용그랩장치에 있어서, 가장 취약점인 그랩장치 하부의 쉬벨축의 회전수단이였던 워엄 및 워엄나사방식에서 탈피하여, 워엄나사의 내마모성을 향상되도록, 기어박스상커버(15)상에 장착된 유압모터(17)의 정역조작에 의해 스플라인유압모터축(17c)에 축결합된 스플라인원동기어(17a)가 평기어(13)를 회전시키므로서, 쉬벨축(11) 하단축이 쉬벨축하부키(9)와 더불어 고정된 집게베이스(1)가 일체로 회동되는 방식이다.The present invention as described above has been removed from the worm and worm screw method, which was the rotation means of the shibel shaft of the lower grab device, which is the most vulnerable for grabbing devices in the wood industry, so as to improve the wear resistance of the worm screw, the gear box upper cover ( The spline drive gear 17a, which is axially coupled to the spline hydraulic motor shaft 17c by the forward and reverse operation of the hydraulic motor 17 mounted on the top 15, rotates the spur gear 13, so that The short axis is a method in which the fixed tong base 1 together with the Shibel shaft lower key 9 are integrally rotated.

이와같이 암집게부(2)와 숫집게부(3)가 장착된 집게베이스(1)가 자재로이 회동시키는 방식은 종전에 워엄과 웜나사로 쉬벨축을 회동시키는 방식으로 인해 원목 하중이 실린 집게부를 회동하는 동작에 의해 워엄나사부의 잦은 마모가 발생하는 문제점을 해결토록한 유용한 고안인 것이다.In this way, the tongs base (1) equipped with the tongs (2) and the tongs (3) is rotated freely. It is a useful design to solve the problem of frequent wear of the worm screw by the operation.
