The invention relates to the technical field of forklift suspension arm devices, and specifically discloses a forklift suspension arm device with a self-locking positioning function. A mounting insertion hole is formed in the back surface of a base; a lifting oil cylinder is arranged at the front end of the upper surface of the base; the top end of a rotary connecting support at the rear end of the upper surface of the base is rotatably connected with the bottom end of a telescopic arm; the bottom surface of the front end of a cantilever connected with the front end of the telescopic arm is movably connected with a hoisting base; the outer end, connected with a telescopic sleeve, of the side surface of the hoisting base is connected with a plate body; the lower surface of the plate body isrotatably sleeved with a hoisting ring; a sliding plate body is slidably clamped to the top of an inner cavity of the mounting insertion hole; the upper surface of the sliding plate body is vertically and fixedly connected with a connecting base; the telescopic end of a positioning oil cylinder on the front surface of the support is rotatably connected with the connecting base; chutes in slidingclamping connection with the connecting base are formed in the positions, corresponding to the mounting insertion hole, of the upper surface of the base; and a resistance increasing layer is arrangedon the lower surface of the sliding plate body. The problems that a suspension arm for a forklift is complex to assemble and position, and objects of different body types are difficult to hoist are solved.

    本发明涉及叉车吊臂装置技术领域,具体公开了一种具有自锁定位功能的叉车吊臂装置,底座背面设有安装插孔,底座上表面前端设有升降油缸,底座上表面后端转动连接支架的顶端与伸缩臂底端转动连接,伸缩臂前端连接的悬臂前端底面与起吊基座活动连接,起吊基座侧面连接伸缩套筒的外端连接有板体,板体的下表面转动套接有起吊环,滑动板体滑动卡接于安装插孔内腔的顶部,滑动板体的上表面垂直固定连接有连接座,支架正面的定位油缸伸缩端与连接座转动连接,底座的上表面对应安装插孔的位置分别开设有与连接座滑动卡接的滑槽,滑动板体的下表面设置有增阻层;解决了叉车用吊臂组装定位复杂以及难以满足对不同体型物件进行吊装的问题。
