The invention relates to the technical field of engineering mechanical arm supports, and discloses engineering mechanical operation arm support return adjusting equipment which comprises a first cantilever and a second cantilever hinged to one end of the first cantilever, a connecting base is installed at the lower end of the first cantilever, and a stabilizing plate is fixedly installed at the lower end of the connecting base. A supporting bracket is fixedly mounted at the lower end of the stabilizing plate, a stabilizing seat is fixedly mounted at the lower end of the supporting bracket, a sliding rod is mounted at the lower end of the stabilizing plate, a first ball is mounted at the lower end of the sliding rod, a through hole is formed in the supporting bracket, and a connecting rod is slidably mounted in the through hole. The sliding rod makes contact with the connecting rod, the circuit is closed, the indicator light is turned on, accurate positioning of the arm support after returning is facilitated, whether the arm support returns or not can be judged manually only according to the situation whether the indicator light is turned on or not, operation is convenient and fast, and returning accuracy is improved.

    本发明涉及工程机械臂架技术领域,且公开了工程机械作业臂架回位调节设备,包括第一悬臂和铰接在第一悬臂一端的第二悬臂,所述第一悬臂的下端安装有连接座,所述连接座的下端固定安装有稳固板,所述稳固板的下端固定安装有支撑托架,所述支撑托架的下端固定安装有稳固座,所述稳固板的下端安装有滑行杆,所述滑行杆的下端安装有第一球体,所述支撑托架上开设有通孔,所述通孔内滑动安装有连杆,稳固板在旋转的过程中,滑行杆与连杆接触,电路闭合,指示灯亮起,便于对回位后的臂架进行精准定位,人工仅通过指示灯是否亮起的情况来就能判断臂架是否回位,操作较为便捷,提高了回位的精准度。
