The invention provides an arm support device and a high-altitude operation machine, under the condition that a luffing mechanism is located at a working position, an arm support mechanism is lifted to a preset maximum height relative to a machine base, and the machine base, the arm support mechanism and the luffing mechanism define a first triangular supporting structure; the locking mechanism is installed on the arm support mechanism and can move from the folding state to the unfolding state under the condition that the luffing mechanism rotates to the working position, the luffing mechanism and the locking mechanism in the folding state are arranged in a spaced mode, and the locking mechanism in the unfolding state can relatively lock the arm support mechanism and the luffing mechanism. And the arm support mechanism is supported on the luffing mechanism through the locking mechanism. While smooth operation of the boom mechanism is guaranteed, safety protection is added through the locking mechanism, a protection effect can be achieved when the luffing mechanism breaks down, the situation that the boom mechanism and the luffing mechanism descend drastically is avoided, the situation that operators are casualty due to descending of the boom mechanism can be effectively avoided, and the working efficiency is improved. And the potential safety hazard of the boom device is eliminated.
本发明提供一种臂架装置及高空作业机械,变幅机构位于工作位置的情况下,臂架机构相对机座举升至预设最大高度,且机座、臂架机构和变幅机构围成第一三角支撑结构;锁止机构,安装于臂架机构,锁止机构能在变幅机构旋转至工作位置的情况下自折叠状态运动至展开状态,变幅机构和处于折叠状态的锁止机构间隔设置,处于展开状态的锁止机构能相对锁止臂架机构和变幅机构,并使臂架机构通过锁止机构支撑于变幅机构。本发明在保证臂架机构顺畅运行的同时,通过锁止机构增加了一道安全保护,能在变幅机构发生故障时起到保护作用,避免臂架机构和变幅机构大幅度下降的情况,能有效避免作业人员因臂架机构下降出现伤亡的情况,消除了臂架装置的安全隐患。
