The invention relates to the field of emergency operation, and provides an arm support and an operation machine.The arm support comprises a telescopic arm, a first valve set and an emergency pipeline, and the telescopic arm comprises an inner cavity; the first valve group is used for being connected with an execution element of the stretching arm section group; the emergency pipeline is arranged in the inner cavity, one end of the emergency pipeline is connected with the first valve set, and the other end of the emergency pipeline is suspended. In order to overcome the defect that in the prior art, under the extreme condition of no electricity, arm support recycling cannot be achieved, according to the arm support, an emergency pipeline is connected to a first valve set, the emergency pipeline is arranged in an inner cavity of a telescopic arm, and under the extreme state of no electricity and the like, the emergency pipeline is connected with an emergency hydraulic system, so that recycling of an extension arm section set is achieved; and the reliability of the emergency recovery boom is improved.

    本发明涉及应急作业领域,提供一种臂架及作业机械,其中,臂架,包括:伸缩臂、第一阀组和应急管道,伸缩臂包括内腔;第一阀组用于与伸展臂节组的执行元件连接;应急管道置于内腔中,应急管道的一端与第一阀组连接,应急管道的另一端悬置。用以解决现有技术中无电的极端情况下,无法实现臂架回收的缺陷,本发明提供的臂架,通过在第一阀组上连接应急管道,应急管道置于伸缩臂内腔中,在无电等极端状态下,通过应急管道与应急液压系统连接,实现伸展臂节组的回收,提高应急回收臂架的可靠性。
