Abstract

본 발명은 조립 작업성이 양호한 부품 개수가 작은 커터 캐치 롤러를 가지며, 소음이 적은 포크 리프트의 승강장치를 제고한다.The present invention has a cutter catch roller with a small number of parts having good assembly workability, and improves the lift device of the forklift with low noise.

상하 한쌍의 리프트 롤러(141, 142)와, 거터 캐치 롤러(20)를 가지는 리프트브래킷(121, 122)이 승강한다. 거터 캐치 롤러(20)는 마스트 레일(40)을 따라서 전동하는 압축 롤러(20)와, 이 압축 롤러를 지지하는 축부(20) 및 이 축부에 대하여 편심한 축심을 가지는 수나사부(30)를 갖는 편심핀(24)과,리르트 브래킷(121, 122)에 부착하기 위한 고정 너트를 가진다. 수나사부(30)의 나사방향은 편심핀(24)이 편심하여 있음으로써 받는 회전 모멘트에 의하여나사의 풀림이 생기지 않는 방향으로 형성되어 있다.The lift brackets 121 and 122 having the upper and lower pairs of lift rollers 141 and 142 and the gutter catch roller 20 are lifted up and down. The gutter catch roller 20 has a compression roller 20 for rolling along the mast rail 40, a shaft portion 20 for supporting the compression roller, and a male screw portion 30 having an axial center eccentric with respect to the shaft portion. An eccentric pin 24 and a fixing nut for attaching to the reit brackets 121 and 122. The screw direction of the male screw part 30 is formed in the direction which does not loosen a screw by the rotation moment which the eccentric pin 24 receives by being eccentric.
